Intranasal steroids vs antihistamines: Which is better for seasonal allergies and conjunctivitis?
EVIDENCE-BASED ANSWER

INTRANASAL STEROIDS PROVIDE BETTER RELIEF for adult sufferers, according to nonstandardized, nonclinically validated scales. Steroids reduce subjective total nasal symptom scores (TNSS)—representing sneezing, itching, congestion, and rhinorrhea—by about 25% more than placebo, whereas oral antihistamines decrease TNSS by 5% to 10% (strength of recommendation [SOR]: B, systematic review of randomized controlled trials [RCTs], most without clinically validated or standardized outcome measures).

Intranasal steroids improve subjective eye symptom scores as well as (or better than) oral antihistamines in adults who also have allergic conjunctivitis (SOR: A, systematic review, RCTs).

 

Evidence summary

The most commonly measured outcomes in allergic rhinitis and conjunctivitis trials are symptom scales, which are neither standardized nor clinically validated. Almost all the studies discussed here calculated outcomes as a percentage change from baseline symptom scores but didn’t provide absolute values, so it isn’t clear whether statistical differences are clinically relevant.

Steroids provide more relief of nasal symptoms
A meta-analysis of 21 randomized placebo-controlled trials (total 2821 patients, average age mid-30s) that compared changes in TNSS with intranasal steroids and oral antihistamines among adults with seasonal allergic rhinitis found that steroids reduced TNSS more than antihistamines.1 Most of the patients had had moderate to severe symptoms for several years.

Investigators calculated percent changes from baseline in mean TNSS, which typically included sneezing, itching, congestion, and rhinorrhea, each usually scored on a scale of 0 to 3.1 Individual RCTs compared one of 3 intranasal steroids (fluticasone, triamcinolone, or budesonide) and one of 3 oral antihistamines (cetirizine, loratadine, or fexofenadine) with placebo; no studies compared medications within classes against each other.1

On individual symptom scores, intranasal steroids reduced sneezing, itching, congestion, and rhinorrhea more than placebo by more than 20%. Both intranasal steroids and oral antihistamines decreased itching and rhinorrhea a similar amount, but antihistamines reduced congestion by only 5% to 10% more than placebo.1

This meta-analysis included only studies reporting TNSS as an outcome, and individual studies used varying TNSS scales. Investigators attributed heterogeneity in the studies to intraclass differences between medications.1

Two drug company-sponsored RCTs (1616 patients combined, average age 30s, moderate to severe allergic rhinitis) published before the meta-analysis also demonstrated that the intranasal steroid fluticasone propionate modestly reduced TNSS compared with the oral antihistamine fexofenadine (1 point vs 1.3 on a scale of 0 to 12).2 TABLE 1 summarizes the results of studies comparing intranasal steroids and oral antihistamines to reduce nasal symptoms.

Results for eye symptoms are mixed
A meta-analysis of 11 RCTs (1317 patients, average age 32) showed no significant difference in relief of eye symptoms between oral antihistamines (dexchlorpheniramine, terfenadine, and loratadine) and intranasal steroids (budesonide, beclomethasone, fluticasone, and triamcinolone) in patients with seasonal allergies, as measured by various symptom scores.3

 

 

 

Three other studies indicated that intranasal steroids (triamcinolone, fluticasone) relieved eye symptoms more effectively than oral antihistamines (loratadine, fexofenadine) based on mean reductions in TNSS, Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and Total Ocular Symptom Score (TOSS).4-6 Of these scoring systems, only the RQLQ has been clinically validated.7

One additional study (including 2 RCTs) showed conflicting results.2 TABLE 2 summarizes the results of studies comparing intranasal steroids and oral antihistamines to relieve eye symptoms.

Antihistamines cost less than steroids and are available OTC
Oral antihistamines are less expensive than intranasal steroids and are available over the counter. The cost of antihistamines ranges from $5.70 to $21.99 for a month of treatment, whereas the cost of intranasal steroids for the same period varies from $60.99 to $149.99.8

In the studies reviewed here, the 2 interventions showed similar harms, including sore throat, epistaxis, and headache.2,4-6

Recommendations

The American Academy of Allergy, Asthma and Immunology’s 2010 guidelines conclude that intranasal steroids are first-line treatment for allergic rhinitis. If the patient prefers, use oral antihistamines.9

The Joint Task Force on Practice Parameters for Allergy and Immunology also recommends intranasal steroids as the most effective medication class for treating allergic rhinitis; no drug within the class is preferable to another. Daily administration is more effective than administration as needed, although the latter is an option. For treating ocular symptoms, intranasal corticosteroids and oral antihistamines work equally well.10

Oral antihistamines are less expensive than intranasal steroids and are available over the counter. The cost of antihistamines ranges from $5.70 to $21.99 for a month of treatment, whereas the cost of intranasal steroids for the same period varies from $60.99 to $149.99.8

In the studies reviewed here, the 2 interventions showed similar harms, including sore throat, epistaxis, and headache.2,4-6

Recommendations

The American Academy of Allergy, Asthma and Immunology’s 2010 guidelines conclude that intranasal steroids are first-line treatment for allergic rhinitis. If the patient prefers, use oral antihistamines.9

The Joint Task Force on Practice Parameters for Allergy and Immunology also recommends intranasal steroids as the most effective medication class for treating allergic rhinitis; no drug within the class is preferable to another. Daily administration is more effective than administration as needed, although the latter is an option. For treating ocular symptoms, intranasal corticosteroids and oral antihistamines work equally well.10

Postcholecystectomy diarrhea: What relieves it?
EVIDENCE-BASED ANSWER

A TRIAL OF A BILE ACID BINDER such as cholestyramine or colestipol may benefit patients with postcholecystectomy diarrhea (strength of recommendation [SOR]: C, case series).

Although postcholecystectomy diarrhea is uncommon and rarely severe, it can be debilitating (SOR: B, prospective case-control study).

 

Evidence summary

A prospective study compared the bowel function of 106 adults (85 women) who underwent laparoscopic cholecystectomy with bowel function of 37 women who had laparoscopic sterilization (and served as controls).1 The investigators gave bowel function questionnaires to both groups before surgery and 2 to 6 months afterward. They found no significant differences in bowel function between the groups.

Of the 6 women in the cholecystectomy group who reported diarrhea, only one had new-onset diarrhea, and it was “mild.” No men reported bowel function changes.1

Case studies suggest benefit from bile acid binders
When postcholecystectomy diarrhea does occur, the best treatment is unclear in the absence of randomized controlled trials. Case reports and case series support using bile acid binders based on the hypothesis that bile acid malabsorption causes the diarrhea.

The largest case series followed 26 postcholecystectomy patients with chronic diarrhea, defined as more than 3 liquid stools in 24 hours for an average of 3.9 years (range, 3 months to 13 years). Twenty-five of the 26 (96%) had severe bile acid malabsorption.

Cholestyramine, in doses of 2 to 12 g/d “normalized bowel movements” in 23 of the 25 patients with malabsorption (92%). When treatment was suspended, diarrhea recurred in 9 of the 23 (39%); bowel habits remained regular in 14 (61%).2

A smaller case series studied 8 patients who had postcholecystectomy diarrhea, defined as more than 4 loose stools in a 24-hour period for 1 to 20 years. Six of the 8 had elevated stool bile acids and stool weight greater than 200 g/24 hours. All 6 had less frequent bowel movements within 72 hours of starting oral cholestyramine at 4 to 16 g/d (adjusting the dose to maintain 1 bowel movement daily). Diarrhea recurred in all of the patients after they stopped cholestyramine.3

A single case report of a 71-year-old man who had 4 to 6 loose stools a day for 4 years after cholecystectomy noted improvement to 2 to 3 stools daily when he was treated with either colestipol or psyllium hydrophilic mucilloid.4

Recommendations

We found no consensus statements regarding treatment of postcholecystectomy diarrhea. A gastroenterology textbook notes that diarrhea occurs in as many as 20% of patients.5 The authors recommend nightly bile acid binders and, in refractory cases, opiate antidiarrheals.

An internal medicine textbook states that postcholecystectomy diarrhea—defined as 3 or more watery bowel movements per day—occurs in 5% to 10% of patients.6 The authors recommend treatment with cholestyramine or colestipol.

What’s the best way to relieve mastitis in breastfeeding mothers?
EVIDENCE-BASED ANSWER

FREQUENT BREAST EMPTYING helps both infectious and noninfectious mastitis (strength of recommendation [SOR]: A, 1 randomized controlled trial [RCT]).

Antibiotics may be useful for women with positive milk cultures (SOR: A, 2 RCTs), but their utility for treating undifferentiated mastitis is unknown (SOR: A, 1 systematic review).

Consider prescribing antibiotics for women whose mastitis symptoms don’t improve after 12 to 24 hours of frequent breast emptying (SOR: C, consensus guideline).

 

Evidence summary

An RCT compared breast emptying every 6 hours with no treatment for inflammatory breast symptoms in 213 women with 339 inflamed breasts.1 Investigators classified symptoms into 3 groups based on milk leukocyte counts (MLC) and cultures from expressed milk (MC): infectious mastitis (MLC >106/mL, MC >103 bacteria/mL; n=165 breasts), noninfectious mastitis (MLC >106/mL, MC <103 bacteria/mL; n=48 breasts), and milk stasis, or inspissated milk (MLC <106/mL, MC <103 bacteria/mL; n=126 breasts).

Breast emptying reduced the mean duration of symptoms in women with infectious mastitis (4.2 vs 6.7 days with no treatment; P<.001) and noninfectious mastitis (3.2 vs 7.9 days with no treatment; P<.001). However, it didn’t shorten mean symptom duration in women with milk stasis (2.1 vs 2.3 days with no treatment; P not significant).1

Moreover, breast emptying allowed more women with infectious and noninfectious mastitis to return to normal lactation within 2 weeks. Rates of return to lactation for women with infectious mastitis were 51% with breast emptying compared with 15% with no treatment (number needed to treat [NNT]=2; 95% confidence interval [CI], 2-5). For women with noninfectious mastitis, the rates of return to lactation within 2 weeks were 96% with breast emptying compared with 21% with no treatment (NNT=1; 95% CI, 1-2).1

Antibiotics plus breast emptying work better than emptying alone
The investigators further randomized a subgroup of women (165 involved breasts) with culture-positive mastitis into 3 treatment groups, each with 55 women: culture-directed antibiotics for 6 days plus breast emptying every 6 hours, breast emptying alone, and no treatment.

Antibiotics improved the rate of return to normal lactation over breast emptying alone (96% vs 51% normal lactation at 2 weeks; NNT=3; 95% CI, 2-3) and no treatment (96% vs 15% normal lactation at 2 weeks, NNT=1; 95% CI, 1-2). They also reduced the mean duration of symptoms (2.1 days with antibiotics vs 4.2 days with breast emptying alone and 6.7 days with no treatment; P<.001 for each).1

Amoxicillin and cephradine produce similar results
A smaller RCT (N=25) compared oral amoxicillin with oral cephradine for women with a clinical diagnosis of mastitis based on oral temperature above 37.6°C, breast tenderness, and erythema.2 Investigators prescribed 7 days of amoxicillin (500 mg every 8 h; n=13) or cephradine (500 mg every 6 h; n=12) and instructed women to continue breastfeeding and apply warm, moist compresses to the involved breast every 4 to 6 hours. They also performed milk cultures on all women. The cultures grew penicillin-resistant staphylococci (15 women; 7 treated with amoxicillin and 8 with cephradine) and penicillin-sensitive streptococci (6 women).

After 7 days, the investigators found no significant differences in fever, breast tenderness, or erythema between the 2 groups (relative risk=0.85; 95% CI, 0.65-1.12, favoring cephradine).2,3 Two treatment failures occurred in the amoxicillin-treated group, both in women who had positive cultures for Staphylococcus aureus.2

A Cochrane systematic review of the 2 RCTs described here concluded that insufficient evidence exists to support or refute antibiotic therapy for treating lactational mastitis.3

Recommendations

The World Health Organization (WHO) recommends continued breastfeeding and improving breastfeeding technique for women with mastitis. WHO advises ensuring proper infant attachment, frequent breastfeeding, and expression of breast milk by hand or pump, if necessary. They urge clinicians to promote continued breastfeeding by providing encouragement and reassurance about its value.4

The Academy of Breastfeeding Medicine (ABM) recommends anti-inflammatory medications for analgesia to allow women with mastitis to continue to breastfeed. Hot packs or a hot shower also may alleviate symptoms.5

WHO and ABM both recommend prescribing a 14-day course of antibiotics effective against S aureus for women whose symptoms don’t improve after breast emptying for 12 to 24 hours.4,5

Antibiotics improved the rate of return to normal lactation over breast emptying alone (96% vs 51% normal lactation at 2 weeks; NNT=3; 95% CI, 2-3) and no treatment (96% vs 15% normal lactation at 2 weeks, NNT=1; 95% CI, 1-2). They also reduced the mean duration of symptoms (2.1 days with antibiotics vs 4.2 days with breast emptying alone and 6.7 days with no treatment; P<.001 for each).1

Amoxicillin and cephradine produce similar results
A smaller RCT (N=25) compared oral amoxicillin with oral cephradine for women with a clinical diagnosis of mastitis based on oral temperature above 37.6°C, breast tenderness, and erythema.2 Investigators prescribed 7 days of amoxicillin (500 mg every 8 h; n=13) or cephradine (500 mg every 6 h; n=12) and instructed women to continue breastfeeding and apply warm, moist compresses to the involved breast every 4 to 6 hours. They also performed milk cultures on all women. The cultures grew penicillin-resistant staphylococci (15 women; 7 treated with amoxicillin and 8 with cephradine) and penicillin-sensitive streptococci (6 women).

After 7 days, the investigators found no significant differences in fever, breast tenderness, or erythema between the 2 groups (relative risk=0.85; 95% CI, 0.65-1.12, favoring cephradine).2,3 Two treatment failures occurred in the amoxicillin-treated group, both in women who had positive cultures for Staphylococcus aureus.2

A Cochrane systematic review of the 2 RCTs described here concluded that insufficient evidence exists to support or refute antibiotic therapy for treating lactational mastitis.3

Recommendations

The World Health Organization (WHO) recommends continued breastfeeding and improving breastfeeding technique for women with mastitis. WHO advises ensuring proper infant attachment, frequent breastfeeding, and expression of breast milk by hand or pump, if necessary. They urge clinicians to promote continued breastfeeding by providing encouragement and reassurance about its value.4

The Academy of Breastfeeding Medicine (ABM) recommends anti-inflammatory medications for analgesia to allow women with mastitis to continue to breastfeed. Hot packs or a hot shower also may alleviate symptoms.5

WHO and ABM both recommend prescribing a 14-day course of antibiotics effective against S aureus for women whose symptoms don’t improve after breast emptying for 12 to 24 hours.4,5

EVIDENCE-BASED ANSWER

FREQUENT BREAST EMPTYING helps both infectious and noninfectious mastitis (strength of recommendation [SOR]: A, 1 randomized controlled trial [RCT]).

Antibiotics may be useful for women with positive milk cultures (SOR: A, 2 RCTs), but their utility for treating undifferentiated mastitis is unknown (SOR: A, 1 systematic review).

Consider prescribing antibiotics for women whose mastitis symptoms don’t improve after 12 to 24 hours of frequent breast emptying (SOR: C, consensus guideline).

 

Evidence summary

An RCT compared breast emptying every 6 hours with no treatment for inflammatory breast symptoms in 213 women with 339 inflamed breasts.1 Investigators classified symptoms into 3 groups based on milk leukocyte counts (MLC) and cultures from expressed milk (MC): infectious mastitis (MLC >106/mL, MC >103 bacteria/mL; n=165 breasts), noninfectious mastitis (MLC >106/mL, MC <103 bacteria/mL; n=48 breasts), and milk stasis, or inspissated milk (MLC <106/mL, MC <103 bacteria/mL; n=126 breasts).

Breast emptying reduced the mean duration of symptoms in women with infectious mastitis (4.2 vs 6.7 days with no treatment; P<.001) and noninfectious mastitis (3.2 vs 7.9 days with no treatment; P<.001). However, it didn’t shorten mean symptom duration in women with milk stasis (2.1 vs 2.3 days with no treatment; P not significant).1

Moreover, breast emptying allowed more women with infectious and noninfectious mastitis to return to normal lactation within 2 weeks. Rates of return to lactation for women with infectious mastitis were 51% with breast emptying compared with 15% with no treatment (number needed to treat [NNT]=2; 95% confidence interval [CI], 2-5). For women with noninfectious mastitis, the rates of return to lactation within 2 weeks were 96% with breast emptying compared with 21% with no treatment (NNT=1; 95% CI, 1-2).1

What is the prognosis for patients with chronic urticaria?
EVIDENCE-BASED ANSWER

THE PROGNOSIS FOR CHRONIC URTICARIA IN PRIMARY CARE IS UNKNOWN; studies in dermatology clinics in multiple countries report complete resolution in approximately one-third of patients with idiopathic chronic urticaria over 1 to 5 years and partial improvement in another third. Patients younger than 30 years with more severe symptoms, or symptoms with physical causes, fared less well (strength of recommendation: B, cohort studies).

 

Evidence summary

A prospective cohort study of 220 patients from an outpatient dermatology center in Amsterdam investigated the natural course of chronic urticaria and angioedema.1 Researchers categorized patients according to subtypes: idiopathic urticaria-angioedema, idiopathic urticaria, idiopathic angioedema, physical and idiopathic urticaria, and physical urticaria only.

The duration of symptoms at enrollment wasn’t reported. Therapy wasn’t controlled and was composed of oral antihistamines, steroids, and other drugs.

One year after enrollment, 35% of patients had complete resolution of symptoms. Resolution rates ranged from a high of 59.6% in patients with idiopathic urticaria-angioedema to a low of 16.4% in patients who had urticaria with a physical cause.

A study finds 1-year control or improvement in chronic urticaria
Another prospective cohort study from an outpatient dermatology center in Brazil evaluated 125 patients with chronic urticaria-angioedema.2 Participants were predominantly adults 20 to 40 years of age, with a mean duration of symptoms of 45 months.

Most patients had idiopathic disease (78%), but some had parasitic and skin infections, medication sensitivities, thyroid disease, and other problems that could contribute to skin hyperreactivity. Therapeutic interventions for underlying conditions or angioedema-urticaria weren’t controlled or reported.

One year after presentation, 58.4% of patients had symptoms “under control,” 31.7% were improved, and 8.9% were unchanged. One patient’s symptoms worsened.

Urticaria is less severe in patients older than 30 years
A prospective cohort study followed 62 patients with urticaria caused by cold from a tertiary referral center in Greece.3 The mean age at presentation was 42 years and the mean duration of symptoms was 10 years. The study followed patients for a mean of 9 years. Therapeutic interventions weren’t controlled or reported

Overall, 29% of patients experienced resolution of symptoms, 41.9% noted improvement, and 29% experienced worsening of symptoms. The mean time to resolution was 5.6 years. The study also found that chronic urticaria was less severe if patients developed the condition after 30 years of age.

Worst prognosis found in patients with cold-related urticaria
A retrospective cohort study identified 544 cases of chronic urticaria and angioedema in 22 years of records from a tertiary referral center in the Netherlands.4 The mean age at presentation was 35 years; patients had been symptomatic an average of 5 years. All patients were sent a questionnaire to fill out; 372 questionnaires were returned.

At 5 years after presentation, symptoms resolved in 29% of patients; at 10 years, the number of resolved cases increased to 44%. Patients with cold-related urticaria had the worst prognosis.

Zafirlukast has no effect
An RCT with a study group of 137 patients (mean age 41 years) compared the effectiveness of zafirlukast vs placebo for treating chronic urticaria symptoms. Zafirlukast showed no significant benefit over placebo; symptoms resolved or improved in 41.3% of all patients after 12 weeks.5

Recommendations

Habif’s Clinical Dermatology states that chronic urticaria:

  • may last for months or years
  • may be subject to lengthy and often un-rewarding evaluation
  • resolves spontaneously in most cases.6

Is cinnamon safe and effective for treating lipid disorders?

Is cinnamon safe and effective for treating lipid disorders?
EVIDENCE-BASED ANSWER

IT’S PROBABLY SAFE, BUT ITS EFFECTIVENESS IS UNCERTAIN. Insufficient evidence exists to determine whether cinnamon improves outcomes in patients with lipid disorders. In healthy patients without hyperlipidemia, cinnamon doesn’t change lipid levels but does cause mild gastrointestinal symptoms. In patients with diabetes, the bulk of the available evidence suggests cinnamon supplementation neither improves serum lipid levels nor causes significant harm (strength of recommendation [SOR]: B, extrapolated from small randomized controlled trials [RCTs] with heterogeneous results).

 

Evidence summary

No large trials with patient-oriented outcomes have evaluated cinnamon as a treatment for hyperlipidemia. One small RCT compared cinnamon with turmeric in 11 healthy individuals, ages 21 to 38 years, without diabetes or hyperlipidemia.

Investigators administered 3 g cinnamon or 2.8 g turmeric daily for 4 weeks; they found no significant change in fasting lipid values. Baseline lipid levels were 155 mg/dL for total cholesterol and 139 mg/dL for triglycerides. Clinical side effects of cinnamon included transient eructation (burping or reflux), headache, and a “burning stomach” sensation.1

RCT with diabetes patients shows some positive results
Four small RCTs whose primary purpose was to investigate the effects of cinnamon supplements on blood glucose control in patients with diabetes also assessed blood lipid levels.

The first RCT studied 30 men and 30 women with type 2 diabetes, mean age 52 years. Patients had had diabetes (controlled with a sulfonylurea) for a mean of 7 years, but had no other medical conditions. Investigators randomized them into 6 groups of 10 subjects, each taking 1, 3, or 6 g of cinnamon or an equal number of placebo capsules daily for 40 days, followed by a 20-day washout period.

At 40 days, cinnamon at 3- and 6-g doses significantly reduced total cholesterol (12%-26% reduction; P<.05), low-density lipoprotein (LDL) (7%-27% reduction; P<.05), and triglycerides (23%-30% reduction; P<.05), but did not change high-density lipoprotein (HDL) levels. Cinnamon at the 1-g dose also reduced triglycerides and total cholesterol.2 Investigators didn’t mention adverse effects.

Other studies find no change in lipids, but no harm either
However, 3 subsequent RCTs with a total of 181 patients found that cinnamon didn’t improve fasting lipid profiles in patients with type 2 diabetes.

In the first study, investigators randomized 25 postmenopausal women (mean age 63 years) with type 2 diabetes (controlled on any of 3 classes of oral medication) to receive either 1.5 g cinnamon or placebo daily for 6 weeks. Mean baseline lipid levels (total cholesterol=190 mg/dL; HDL=50 mg/dL; LDL=116 mg/dL; and triglycerides=113 mg/dL) did not change significantly. Investigators didn’t mention adverse effects.3

The second RCT, involving 79 patients (mean age 63 years) with type 2 diabetes on oral therapy, also found that 3 g cinnamon daily didn’t change lipid profiles over 4 months. Baseline lipid levels were: total cholesterol=209 mg/dL; HDL=56 mg/dL; LDL=135 mg/dL; and triglycerides=170 mg/dL. Investigators reported no adverse effects.4

The third RCT evaluated the effects of cinnamon supplementation compared with placebo on lipid levels and glycosylated hemoglobin (HbA1c) for 77 individuals with type 2 diabetes. Investigators recruited subjects of any age with diabetes controlled on a stable dose of oral agents and randomized them to receive either 500 mg cinnamon or placebo twice daily.

Subjects’ mean baseline cholesterol levels were: total cholesterol=170 mg/dL; HDL= 44 mg/dL; LDL=102 mg/dL; and triglycerides=132 mg/dL. There was no difference from baseline in fasting glucose, cholesterol levels (total, HDL, or LDL), or triglycerides at monthly intervals over 3 months, nor was there any change in HbA1c from baseline to 3 months.5

Recommendations

The American Diabetes Association states that cinnamon produces no benefit for people with diabetes.6 The Mayo Clinic states that there is little evidence that cinnamon reduces cholesterol levels, and does not recommend cinnamon as a treatment for high cholesterol.7

EVIDENCE-BASED ANSWER

IT’S PROBABLY SAFE, BUT ITS EFFECTIVENESS IS UNCERTAIN. Insufficient evidence exists to determine whether cinnamon improves outcomes in patients with lipid disorders. In healthy patients without hyperlipidemia, cinnamon doesn’t change lipid levels but does cause mild gastrointestinal symptoms. In patients with diabetes, the bulk of the available evidence suggests cinnamon supplementation neither improves serum lipid levels nor causes significant harm (strength of recommendation [SOR]: B, extrapolated from small randomized controlled trials [RCTs] with heterogeneous results).

 

Evidence summary

No large trials with patient-oriented outcomes have evaluated cinnamon as a treatment for hyperlipidemia. One small RCT compared cinnamon with turmeric in 11 healthy individuals, ages 21 to 38 years, without diabetes or hyperlipidemia.

Investigators administered 3 g cinnamon or 2.8 g turmeric daily for 4 weeks; they found no significant change in fasting lipid values. Baseline lipid levels were 155 mg/dL for total cholesterol and 139 mg/dL for triglycerides. Clinical side effects of cinnamon included transient eructation (burping or reflux), headache, and a “burning stomach” sensation.1

RCT with diabetes patients shows some positive results
Four small RCTs whose primary purpose was to investigate the effects of cinnamon supplements on blood glucose control in patients with diabetes also assessed blood lipid levels.

The first RCT studied 30 men and 30 women with type 2 diabetes, mean age 52 years. Patients had had diabetes (controlled with a sulfonylurea) for a mean of 7 years, but had no other medical conditions. Investigators randomized them into 6 groups of 10 subjects, each taking 1, 3, or 6 g of cinnamon or an equal number of placebo capsules daily for 40 days, followed by a 20-day washout period.

At 40 days, cinnamon at 3- and 6-g doses significantly reduced total cholesterol (12%-26% reduction; P<.05), low-density lipoprotein (LDL) (7%-27% reduction; P<.05), and triglycerides (23%-30% reduction; P<.05), but did not change high-density lipoprotein (HDL) levels. Cinnamon at the 1-g dose also reduced triglycerides and total cholesterol.2 Investigators didn’t mention adverse effects.

Other studies find no change in lipids, but no harm either
However, 3 subsequent RCTs with a total of 181 patients found that cinnamon didn’t improve fasting lipid profiles in patients with type 2 diabetes.

In the first study, investigators randomized 25 postmenopausal women (mean age 63 years) with type 2 diabetes (controlled on any of 3 classes of oral medication) to receive either 1.5 g cinnamon or placebo daily for 6 weeks. Mean baseline lipid levels (total cholesterol=190 mg/dL; HDL=50 mg/dL; LDL=116 mg/dL; and triglycerides=113 mg/dL) did not change significantly. Investigators didn’t mention adverse effects.3

The second RCT, involving 79 patients (mean age 63 years) with type 2 diabetes on oral therapy, also found that 3 g cinnamon daily didn’t change lipid profiles over 4 months. Baseline lipid levels were: total cholesterol=209 mg/dL; HDL=56 mg/dL; LDL=135 mg/dL; and triglycerides=170 mg/dL. Investigators reported no adverse effects.4

The third RCT evaluated the effects of cinnamon supplementation compared with placebo on lipid levels and glycosylated hemoglobin (HbA1c) for 77 individuals with type 2 diabetes. Investigators recruited subjects of any age with diabetes controlled on a stable dose of oral agents and randomized them to receive either 500 mg cinnamon or placebo twice daily.

Subjects’ mean baseline cholesterol levels were: total cholesterol=170 mg/dL; HDL= 44 mg/dL; LDL=102 mg/dL; and triglycerides=132 mg/dL. There was no difference from baseline in fasting glucose, cholesterol levels (total, HDL, or LDL), or triglycerides at monthly intervals over 3 months, nor was there any change in HbA1c from baseline to 3 months.5

Recommendations

The American Diabetes Association states that cinnamon produces no benefit for people with diabetes.6 The Mayo Clinic states that there is little evidence that cinnamon reduces cholesterol levels, and does not recommend cinnamon as a treatment for high cholesterol.7

How should we monitor men receiving testosterone replacement therapy?
EVIDENCE-BASED ANSWER

MONITOR HEMATOCRIT AND BONE MINERAL DENSITY (BMD) (strength of recommendation [SOR]: B, meta-analysis of non–patient-oriented outcomes). Monitoring prostate-specific antigen (PSA), performing prostate digital rectal examination, and observing symptom response to testosterone are also recommended, although direct evidence is lacking (SOR: C, consensus opinion).

Monitoring lipid levels is unnecessary (SOR: A, based on several meta-analyses), as is monitoring testosterone levels (SOR C, consensus opinion). Unless the patient is taking oral testosterone, no evidence exists for or against monitoring liver function (SOR: C, consensus opinion).

 

Evidence summary

A hematocrit >50% is the most frequent testosterone-related adverse event in clinical trials. In a meta-analysis of 19 randomized controlled trials (RCTs)—with a total of 1084 subjects, 651 on testosterone, 433 on placebo—testosterone-treated men were nearly 4 times as likely as placebo-treated men to have a hematocrit >50% (odds ratio [OR]=3.67; 95% confidence interval [CI], 1.82-7.51; number needed to harm [NNH]=14).1 The clinical significance of the increase is unclear.

Increased BMD at lumbar spine
A meta-analysis of 5 RCTs with a total of 264 subjects (135 on testosterone, 129 on placebo) demonstrated a 3.7% (95% CI, 1.0%-6.4%) absolute increase over baseline in lumbar spine BMD after ?12 to 36 months of treatment.2 However, pooled effects on lumbar spine BMD across all studies failed to reach statistical significance because of differences in baseline bone density among subjects (BMD increase=0.03 g/cm2; 95% CI, 0-0.07).

No studies in this meta-analysis showed statistically significant improvement in BMD at the femoral neck. We found no studies that demonstrated reduced fracture risk in patients taking testosterone replacement.

No correlation between testosterone therapy and cancer

Although testosterone can stimulate the growth of locally advanced and metastatic prostate cancer,3 at least 16 longitudinal studies have failed to show any correlation between testosterone replacement and the development of malignancy.4 In the previously mentioned meta-analysis of 19 RCTs, rates of prostate cancer, PSA >4 ng/mL, increase in International Prostate Symptom Score (IPSS) >4, and prostate biopsies were all numerically higher in testosterone-treated men, but the differences between the testosterone and placebo groups weren’t statistically significant.1 Moreover, the average serum PSA level in the testosterone-treated men increased only 0.3 ng/mL from a baseline of 1.3 ng/mL.

 

 

 

Testosterone lowers total cholesterol
A meta-analysis of 30 RCTs (1642 men, 808 on testosterone therapy, 834 on placebo) that assessed testosterone’s effect on lipid levels found that testosterone reduced total cholesterol levels by 16 mg/dL (95% CI, 6-26 mg/dL); effects on all other lipid fractions weren’t significant.5

A second meta-analysis of 16 RCTs (578 men, 320 on testosterone therapy, 258 on placebo) similarly showed that testosterone lowered total cholesterol levels by 8 mg/dL (95% CI, 4-14 mg/dL) and that its effects on other lipid fractions weren’t significant.2 The previously mentioned meta-analyses of 19 and 30 RCTs found no significant difference in cardiovascular events between testosterone- and placebo-treated groups.1,5

Optimal testosterone level is unknown
Data are inadequate to determine the optimal serum level of testosterone for efficacy and safety.3 Expert opinion suggests that because therapy is empiric, monitoring clinical response may help guide treatment more than testosterone level.6

What about the liver?
Oral testosterone can be associated with hepatotoxicity; it is seldom used in the United States. Liver monitoring is unnecessary for patients receiving testosterone by injection, patch, or transbuccal tablet.7,8

Recommendations

Consensus guidelines for monitoring men on testosterone therapy overlap considerably with regard to monitoring clinical effectiveness, prostate measures, hematocrit, and BMD (TABLE).3,6,9,10 Assessing testosterone level is recommended, with the aim of achieving levels in the mid-normal range.10

Do intra-articular steroid injections affect glycemic control in patients with diabetes?
EVIDENCE-BASED ANSWER

YES, BUT THE CLINICAL IMPORTANCE IS MINIMAL. A single intra-articular steroid injection into the knee produces acute hyperglycemia for 2 or 3 days in patients with diabetes who otherwise have good glucose control (strength of recommendation [SOR]: B, small cohort studies).

Intra-articular steroid injections into the shoulder may briefly raise postprandial (but not mean) glucose levels with larger and repeated doses (SOR: C, extrapolated from heterogenous and mixed cohort studies).

 

Evidence summary

Two prospective cohort studies evaluated the effect on glycemic control of a single glucocorticoid injection into the knee of patients with controlled type 2 diabetes (glycosylated hemoglobin A1c <7.0%). The first enrolled 9 patients with symptomatic osteoarthritis of the knee unresponsive to 3 months of nonsteroidal anti-inflammatory drugs (NSAIDs).1 All received a 50-mg injection of methylprednisolone acetate after maximal aspiration of any joint fluid. No changes were made to the diabetes care regimen, including medication, diet, or exercise prescriptions.

With self-monitoring 6 times a day during the week after the injection, 7 patients showed an increase over baseline blood glucose levels of more than 2 standard deviations; values typically rose above 300 mg/dL. Peak blood sugar elevation occurred 5 to 84 hours after injection; the hyperglycemic effect lasted for 2 or 3 days.

In a second cohort study, 6 patients received a knee injection of 1 mL Celestone Chronodose (3 mg betamethasone acetate and 3 mg betamethasone sodium phosphate, comparable in anti-inflammatory and glucocorticoid potency to 32 mg methylprednisolone acetate).2 Patients monitored their blood glucose 6 times a day for 1 week; investigators measured fructosamine levels (a measure of intermediate-term glucose control) at baseline and again 2 weeks after injection.

The injection produced hyperglycemia in all participants, with peak blood glucose levels ranging from 251 to 430 mg/dL and time to peak glucose usually less than 6 hours. Fructosamine levels didn’t change significantly.

No change in glucose after a single shoulder injection
Two studies evaluated the effect of a single shoulder injection. One prospective cohort study included 18 patients with diabetes (type not specified, mean A1c=7.6%).3 All had shoulder pain unresponsive to NSAIDs for more than a month, had not changed diabetes medications within the preceding 2 weeks, and had not had steroid therapy within the preceding 3 months.

All patients received a single injection containing 35 mg methylprednisolone acetate into the anterior glenohumeral joint. They monitored their blood glucose levels 6 times a day for 1 week and had a fructosamine level drawn before injection and 2 weeks afterward. The injection produced no significant change in mean blood glucose or fructosamine levels.

But repeated shoulder injections raise postprandial glucose
In contrast, another prospective cohort study followed 11 patients (8 with diabetes) who received 3 injections of 3.75 mg cortivazol (comparable to 50 mg methylprednisolone acetate) at 3-day intervals into 1 shoulder joint.4 Investigators checked fasting and postprandial glucose levels before the first injection and on post-treatment days 1, 7, and 21.

The shoulder injections elevated post-prandial glucose levels (from 170±60 mg/dL at baseline to 258±100 mg/dL on day 1 and 252±87 mg/dL on day 7; P<.05 for both comparisons). Mean fasting glucose levels didn’t change, however.

Recommendations

The American Academy of Orthopedic Surgeons treatment guidelines for osteoarthritis of the knee don’t discuss possible adverse effects from steroid injections.5 The American Diabetes Association makes no recommendations regarding steroid injections in patients with diabetes.

Does chocolate have cardiovascular benefits?

Does chocolate have cardiovascular benefits?
EVIDENCE-BASED ANSWER

YES, EATING CHOCOLATE REDUCES BLOOD PRESSURE in the short term (strength of recommendation [SOR]: B, a meta-analysis and individual randomized controlled trials [RCTs]). No studies, however, have evaluated the long-term cardiovascular effects of chocolate.

Chocolate contains high levels of flavonol; a diet rich in flavonoids is associated with reduced death rates from coronary heart disease (SOR: B, prospective observational studies, which didn’t evaluate chocolate intake specifically).

 

Evidence summary

A meta-analysis and 3 subsequent single-blinded RCTs showed a short-term decrease in blood pressure with daily consumption of chocolate. The meta-analysis was comprised of 5 randomized controlled parallel-group or crossover studies with a total of 173 adult patients, both normotensive and hypertensive. Patients ate dark chocolate, high-flavonol milk chocolate, white chocolate, or chocolate without flavonol daily for 14 to 15 days. Four studies used 100 to 105 g (approximately 3 oz) of chocolate (480 calories, 500 mg polyphenols, including flavonol), and 1 used 46 g (240 calories, 213 mg flavonol). Investigators didn’t report the percent of cocoa in the chocolate used.1

Dark chocolate and high-flavonol milk chocolate significantly reduced both systolic blood pressure (–4.7 mm Hg; 95% confidence interval [CI], –7.6 to –1.8 mm Hg; P=.002) and diastolic pressure (–2.8 mm Hg; 95% CI, –4.8 to –0.8 mm Hg; P=.006). The study using the 46-g dose found no difference in blood pressure. Removing this outlier from the analysis didn’t alter the mean blood pressure changes.1

From hypertensive to prehypertensive with help from chocolate
An RCT evaluated 44 adults, 56 to 73 years of age, with untreated upper-range prehypertension or stage 1 hypertension without concomitant risk factors. Subjects consumed either 6.3 g (30 kcal) per day of dark chocolate (50% cocoa) or polyphenol-free (hence flavonol-free) white chocolate for 18 weeks.2 Dark chocolate significantly reduced systolic and diastolic blood pressures (systolic: –2.9±1.6 mm Hg; P<.001; diastolic: –1.9±1.0 mm Hg; P<.001) compared with white chocolate.

Four patients who ate dark chocolate (18%) were reclassified from “hypertensive” to “prehypertensive.” None achieved lower-range prehypertension (<130/85) or optimal blood pressure, however. To place this finding in clinical perspective, the authors cite data from the Framingham Heart Study indicating that a 3-mm Hg reduction in systolic blood pressure should reduce the relative risk of stroke mortality by 8%, of mortality from coronary artery disease by 5%, and of all-cause mortality by 4%.2

 

 

 

More evidence of benefit of dark chocolate
A crossover RCT evaluated 19 hypertensive patients with glucose intolerance, but not overt diabetes, who ate either 100 g of flavonol-rich dark chocolate (50% cocoa) or 100 g of flavonol-free white chocolate for 15 days. Dark chocolate significantly reduced both 24-hour ambulatory systolic blood pressure (–4.52±3.94 mm Hg; P<.0001) and diastolic pressure (–4.17±3.29 mm Hg; P<.0001) compared with white chocolate. It also significantly decreased clinical blood pressure readings (systolic: –3.82±2.40 mm Hg; P<.0001; diastolic: –3.92±1.98 mm Hg; P<.0001).3

Another RCT evaluated blood pressure in 45 healthy adults given a 74-g dark chocolate bar (30% cocoa) or a 74-g placebo bar. Blood pressure decreased significantly 2 hours afterwards: –3.2±5.8 mm Hg systolic (P<.001) and –1.4±3.9 mm Hg diastolic (P<.001).4

Sugarless, but not sugared, cocoa shows effects on blood pressure
One week later, investigators compared 2 cups of cocoa (22 g cocoa powder) with 2 cups of sugarless cocoa and placebo. They found significant blood pressure reduction only with the sugarless drink. This study was the only one that reported sponsorship by a chocolate manufacturer.4

Long-term high-flavonoid consumption linked to lower heart disease mortality
A systematic review evaluated the long-term effects of a high-flavonoid diet over a period of 5 to 26 years. The review didn’t measure chocolate intake specifically, although the authors report that both milk and dark chocolate (percent cocoa not specified) are high in flavonoids, containing about 3 to 5 times as much as a comparable amount of black tea or red wine. Eleven prospective observational studies (N=190,000) met the criteria for this review.

Investigators compared occurrence and mortality rates for coronary heart disease and myocardial infarction among participants in the highest and lowest tertiles of flavonoid consumption. Participants in the highest tertile had significantly lower mortality from coronary heart disease than the lowest tertile, with a relative risk of 0.81 (95% CI, 0.71-0.92; no number needed to treat was available).5

Recommendations

We couldn’t find recommendations from major medical organizations. A Natural Medicines Comprehensive Database monograph states that consuming dark chocolate may modestly reduce blood pressure, but not enough evidence exists to rate chocolate’s effectiveness for cardiovascular disease, hypercholesterolemia, or isolated systolic hypertension.6

The US Food and Drug Administration warned one candy manufacturer against claiming that its chocolate-containing candy bars were “heart healthy,” noting that the candy bars also contained high levels of saturated fats.7

An RCT evaluated 44 adults, 56 to 73 years of age, with untreated upper-range prehypertension or stage 1 hypertension without concomitant risk factors. Subjects consumed either 6.3 g (30 kcal) per day of dark chocolate (50% cocoa) or polyphenol-free (hence flavonol-free) white chocolate for 18 weeks.2 Dark chocolate significantly reduced systolic and diastolic blood pressures (systolic: –2.9±1.6 mm Hg; P<.001; diastolic: –1.9±1.0 mm Hg; P<.001) compared with white chocolate.

Four patients who ate dark chocolate (18%) were reclassified from “hypertensive” to “prehypertensive.” None achieved lower-range prehypertension (<130/85) or optimal blood pressure, however. To place this finding in clinical perspective, the authors cite data from the Framingham Heart Study indicating that a 3-mm Hg reduction in systolic blood pressure should reduce the relative risk of stroke mortality by 8%, of mortality from coronary artery disease by 5%, and of all-cause mortality by 4%.2

 

 

 

More evidence of benefit of dark chocolate
A crossover RCT evaluated 19 hypertensive patients with glucose intolerance, but not overt diabetes, who ate either 100 g of flavonol-rich dark chocolate (50% cocoa) or 100 g of flavonol-free white chocolate for 15 days. Dark chocolate significantly reduced both 24-hour ambulatory systolic blood pressure (–4.52±3.94 mm Hg; P<.0001) and diastolic pressure (–4.17±3.29 mm Hg; P<.0001) compared with white chocolate. It also significantly decreased clinical blood pressure readings (systolic: –3.82±2.40 mm Hg; P<.0001; diastolic: –3.92±1.98 mm Hg; P<.0001).3

Another RCT evaluated blood pressure in 45 healthy adults given a 74-g dark chocolate bar (30% cocoa) or a 74-g placebo bar. Blood pressure decreased significantly 2 hours afterwards: –3.2±5.8 mm Hg systolic (P<.001) and –1.4±3.9 mm Hg diastolic (P<.001).4

Sugarless, but not sugared, cocoa shows effects on blood pressure
One week later, investigators compared 2 cups of cocoa (22 g cocoa powder) with 2 cups of sugarless cocoa and placebo. They found significant blood pressure reduction only with the sugarless drink. This study was the only one that reported sponsorship by a chocolate manufacturer.4

Long-term high-flavonoid consumption linked to lower heart disease mortality
A systematic review evaluated the long-term effects of a high-flavonoid diet over a period of 5 to 26 years. The review didn’t measure chocolate intake specifically, although the authors report that both milk and dark chocolate (percent cocoa not specified) are high in flavonoids, containing about 3 to 5 times as much as a comparable amount of black tea or red wine. Eleven prospective observational studies (N=190,000) met the criteria for this review.

Investigators compared occurrence and mortality rates for coronary heart disease and myocardial infarction among participants in the highest and lowest tertiles of flavonoid consumption. Participants in the highest tertile had significantly lower mortality from coronary heart disease than the lowest tertile, with a relative risk of 0.81 (95% CI, 0.71-0.92; no number needed to treat was available).5

Recommendations

We couldn’t find recommendations from major medical organizations. A Natural Medicines Comprehensive Database monograph states that consuming dark chocolate may modestly reduce blood pressure, but not enough evidence exists to rate chocolate’s effectiveness for cardiovascular disease, hypercholesterolemia, or isolated systolic hypertension.6

The US Food and Drug Administration warned one candy manufacturer against claiming that its chocolate-containing candy bars were “heart healthy,” noting that the candy bars also contained high levels of saturated fats.7

EVIDENCE-BASED ANSWER

YES, EATING CHOCOLATE REDUCES BLOOD PRESSURE in the short term (strength of recommendation [SOR]: B, a meta-analysis and individual randomized controlled trials [RCTs]). No studies, however, have evaluated the long-term cardiovascular effects of chocolate.

Chocolate contains high levels of flavonol; a diet rich in flavonoids is associated with reduced death rates from coronary heart disease (SOR: B, prospective observational studies, which didn’t evaluate chocolate intake specifically).

 

Evidence summary

A meta-analysis and 3 subsequent single-blinded RCTs showed a short-term decrease in blood pressure with daily consumption of chocolate. The meta-analysis was comprised of 5 randomized controlled parallel-group or crossover studies with a total of 173 adult patients, both normotensive and hypertensive. Patients ate dark chocolate, high-flavonol milk chocolate, white chocolate, or chocolate without flavonol daily for 14 to 15 days. Four studies used 100 to 105 g (approximately 3 oz) of chocolate (480 calories, 500 mg polyphenols, including flavonol), and 1 used 46 g (240 calories, 213 mg flavonol). Investigators didn’t report the percent of cocoa in the chocolate used.1

Dark chocolate and high-flavonol milk chocolate significantly reduced both systolic blood pressure (–4.7 mm Hg; 95% confidence interval [CI], –7.6 to –1.8 mm Hg; P=.002) and diastolic pressure (–2.8 mm Hg; 95% CI, –4.8 to –0.8 mm Hg; P=.006). The study using the 46-g dose found no difference in blood pressure. Removing this outlier from the analysis didn’t alter the mean blood pressure changes.1

How does pentoxifylline affect survival of patients with alcoholic hepatitis?
EVIDENCE-BASED ANSWER

Pentoxifylline improves short-term survival in patients admitted to the hospital with severe alcoholic hepatitis (strength of recommendation [SOR]: B, a single published randomized controlled trial [RCT]). Pentoxifylline does not improve survival when it is substituted for steroids in hospitalized patients who aren’t responding to steroids (SOR: C, case series).

 

Evidence summary

Patients with severe acute alcoholic hepatitis have elevated levels of serum tumor necrosis factor (TNF), suggesting that TNF release may play a role in liver inflammation.1 Because pentoxifylline inhibits TNF synthesis, it has been evaluated as a potential therapy for alcoholic hepatitis.

Decreases in mortality and hepatorenal syndrome

In a hospital-based clinical trial, 101 patients admitted with severe alcoholic hepatitis (mean age 42 years, 74% men) were randomized to oral pentoxifylline 400 mg twice a day or placebo (vitamin B12 tablets) for 4 weeks.1 The main outcome measures were short-term survival and progression to hepatorenal syndrome. Severe alcoholic hepatitis was defined as a Maddrey discriminant factor (DF) >32, jaundice, and at least one of the following: tender hepatomegaly, fever, leukocytosis, hepatic encephalopathy, or hepatic systolic bruit. The DF is calculated as follows: 4.6 × [prothrombin time in seconds – control time] + bilirubin (mg/dL). Medical management was “individualized according to each patient’s condition.”

Pentoxifylline therapy was associated with decreased mortality during the index hospitalization (relative risk [RR]=0.59; 95% confidence interval [CI], 0.35-0.97; number needed to treat [NNT]=5). Hepatorenal syndrome also decreased (RR=0.29; 95% CI, 0.13-0.65; NNT=4). Patients in the pentoxifylline group tended to have more headaches and gastrointestinal side effects, but no other serious health hazards were observed.

 

 

In a recently published abstract, 50 patients with severe alcoholic hepatitis (defined as DF >32) were enrolled in a randomized, double-blind, placebo-controlled trial of oral pentoxifylline, 400 mg twice a day or placebo for 4 weeks.2 Short-term survival and changes in laboratory values (TNF, creatinine, and DF) were the primary outcome measures.

Survival was 76% in the pentoxifylline group compared with 60% in the placebo group (P not given). In the sub-group of patients who died, however, hepatorenal syndrome was the cause of death in 83% of the pentoxifylline group and 60% of the placebo group (P not given).

In a 1991 pilot study, also published only in abstract form, 22 patients admitted to the hospital with severe alcoholic hepatitis were randomized to receive oral pentoxifylline (1200 mg daily) or placebo for 10 days. Serum creatinine dropped 0.3 mg/dL in the treatment group and rose 2.1 mg/dL in the control group (P<.05). At 30 days, 3 patients in the control group had died compared with 1 in the treatment group (P=not significant).3

 

It’s not effective for patients who don’t respond to steroids

A cohort study evaluated the effect of switching to pentoxifylline in hospitalized patients with severe alcoholic hepatitis who didn’t respond to initial therapy with steroids. Researchers identified 121 patients who were treated initially with 40 mg oral prednisolone daily. The 36 patients who failed to show a drop in bilirubin levels within 7 days were switched to oral pentoxifylline, 400 mg twice a day.

In the pentoxifylline group, 69% of patients died within 2 months, 27.6% of whom had some form of renal insufficiency. This outcome wasn’t statistically different from that of 58 matched historical controls with severe alcoholic hepatitis who were maintained on oral prednisolone despite failure to respond within the first week of therapy (65% mortality, 20% with renal insufficiency).4

Recommendations

The American College of Gastroenterology doesn’t recommend giving pentoxifylline to patients with severe alcoholic hepatitis, citing lack of evidence for improvement of patient-oriented outcomes.5 However, a group of French hepatologists consider pentoxifylline a reasonable alternative to corticosteroids for severe acute alcoholic hepatitis based on the studies cited here.6

More than 80% of women with a first-trimester spontaneous abortion have complete natural passage of tissue within 2 to 6 weeks with no higher complication rate than that from surgical intervention (strength of recommendation [SOR]: A, based on multiple randomized controlled trials [RCTs] and cohort studies). Expectant management is successful within 2 to 6 weeks without increased complications in 80% to 90% of women with first-trimester incomplete spontaneous abortion and 65% to 75% of women with first-trimester missed abortion or anembryonic gestation (presenting with spotting or bleeding and ultrasound evidence of fetal demise) (SOR: B, based on multiple cohort studies). There is no difference in short-term psychological outcomes between expectant and surgical management (SOR: B, based on RCT). Women experiencing spontaneous abortion with unstable vital signs, uncontrolled bleeding, or evidence of infection should be considered for surgical evacuation (SOR: C, expert opinion).

A spontaneous abortion can be a very distressing event for a woman and her family; and helping a patient through the complex medical and emotional issues that arise due to the miscarriage stretches the skills of a compassionate clinician. Fortunately, family physicians are ideally positioned to empathize with families, explain treatment options, and expedite medical procedures. This evidence summary gives clear information on outcomes that physicians can share with their patients; however, most women quickly know what they want regarding retained products of conception. Adoption of a wait-and-see approach is common, but a substantial minority wants closure and presses for surgical therapy. Now both groups can be reassured that their choices are equally safe, and physicians can comfortably comply with their patients’ wishes.

 

Evidence summary

A systematic review of 18 studies, including 3 RCTs, compared outcomes for expectant management (545 women) vs surgical evacuation (1408 women) for first-trimester spontaneous abortion.1 A successful first-trimester spontaneous abortion was defined as vaginal bleeding for 3 weeks or less, fully expelled products of conception by 14 days, and no complications (infection, transfusion, uterine perforation, hospitalization, or death). Expectant management was successful in 93% overall, and 80% using only the data from RCTs.

An observational study evaluated 1096 consecutive patients with suspected first-trimester abortion, classified by ultrasound as complete, incomplete, missed, or anembryonic.2 In the latter 3 categories, patients chose expectant management (478) or immediate surgical evacuation (208). Those choosing expectant management were monitored weekly and offered surgical evacuation if their abortion was incomplete after 1 month (TABLE). Complications arose in 6 of 451 patients (1%) managed expectantly for up to 46 days, and in 5 of 208 patients (2%) managed surgically (not statistically significant). One patient in the expectant group had emergency surgery and blood transfusion.2

A smaller observational study evaluated 108 women with first-trimester missed abortions or anembryonic pregnancies who chose either expectant (85 women) or surgical management. They were followed with weekly ultrasound (including color Doppler imaging) and serum β-hCG for up to 1 month. Fifty-three (62%) completed a spontaneous abortion at 14 days and 71 (84%) at 28 days. There were no significant differences in the rate of complications.3

A prospective trial compared psychological morbidity for 86 women with ultrasound-confirmed first-trimester missed abortions, randomized to expectant or surgical management. At 2 weeks, a self-administered questionnaire about the experience of pregnancy loss found no significant difference in psychological reactions. No increase was seen in anxiety or depression symptoms between women who had miscarried and healthy nonpregnant working women aged 19 to 39 years.4

Expert opinion recommends that women with spontaneous abortion beyond 13 weeks, a temperature >100.4° F, unstable blood pressure, uncontrolled vaginal bleeding, or evidence of endometritis or pelvic inflammatory disease should have surgical evacuation.2

Recommendations from others

UpToDate recommends expectant management for stable women who do not want any medical or surgical intervention, and are willing to wait for expulsion to occur. Surgical evacuation is recommended for women who are not stable because of bleeding or infection or for those who want immediate, definitive treatment of the nonviable pregnancy.5
