A new study from Orange County, California, shows how Candida auris, an emerging pathogen, was successfully identified and contained in long-term acute care hospitals (LTACHs) and ventilator-capable skilled-nursing facilities (vSNFs).

Lead author Ellora Karmarkar, MD, MSc, formerly an epidemic intelligence service officer with the Centers for Disease Control and Prevention and currently with the California Department of Public Health, said in an interview that the prospective surveillance of urine cultures for C. auris was prompted by “seeing what was happening in New York, New Jersey, and Illinois [being] pretty alarming for a lot of the health officials in California, [who] know that LTACHs are high-risk facilities because they take care of really sick people. Some of those people are there for a very long time.”

Therefore, the study authors decided to focus their investigations there, rather than in acute care hospitals, which were believed to be at lower risk for C. auris outbreaks.

The Orange County Health Department, working with the California Department of Health and the CDC, asked labs to prospectively identify all Candida isolates in urines from LTACHs between September 2018 and February 2019. Normally, labs do not speciate Candida from nonsterile body sites.

Dan Diekema, MD, an epidemiologist and clinical microbiologist at the University of Iowa, Iowa City, who was not involved in the study, told this news organization, “Acute care hospitals really ought to be moving toward doing species identification of Candida from nonsterile sites if they really want to have a better chance of detecting this early.”

The OCHD also screened LTACH and vSNF patients with composite cultures from the axilla-groin or nasal swabs. Screening was undertaken because 5%-10% of colonized patients later develop invasive infections, and 30%-60% die.

The first bloodstream infection was detected in May 2019. Per the report, published online Sept. 7 in Annals of Internal Medicine, “As of 1 January 2020, of 182 patients, 22 (12%) died within 30 days of C. auris identification; 47 (26%) died within 90 days. One of 47 deaths was attributed to C. auris.” Whole-genome sequencing showed that the isolates were all closely related in clade III.

Experts conducted extensive education in infection control at the LTACHs, and communication among the LTACHs and between the long-term facilities and acute care hospitals was improved. As a result, receiving facilities accepting transfers began culturing their newly admitted patients and quickly identified 4 of 99 patients with C. auris who had no known history of colonization. By October 2019, the outbreak was contained in two facilities, down from the nine where C. auris was initially found.

Dr. Diekema noted, “The challenge, of course, for a new emerging MDRO [multidrug-resistant organism] like Candida auris, is that the initial approach, in general, has to be almost passive, when you have not seen the organism. ... Passive surveillance means that you just carefully monitor your clinical cultures, and the first time you detect the MDRO of concern, then you begin doing the point prevalence surveys. ... This [prospective] kind of approach is really good for how we should move forward with both initial detection and containment of MDRO spread.”

Many outbreak studies are confined to a particular institution. Authors of an accompanying editorial commented that this study “underlines the importance of proactive protocols for outbreak investigations and containment measures across the entirety of the health care network serving at-risk patients.”

In her research, Dr. Karmarkar observed that, “some of these facilities don’t have the same infrastructure and infection prevention and control that an acute care hospital might.”

She said in an interview that, “one of the challenges was that people were so focused on COVID that they forgot about the MDROs. ... Some of the things that we recommend to help control Candida auris are also excellent practices for every other organism including COVID care. ... What I appreciated about this investigation is that every facility that we went to was so open to learning, so happy to have us there. They’re very interested in learning about Candida auris and understanding what they could do to control it.”

While recent attention has been on the frightening levels of multidrug resistance in C. auris, Dr. Karmarkar concluded that the “central message in our investigation is that with the right effort, the right approach, and the right team this is an intervenable issue. It’s not inevitable if the attention is focused on it to pick it up early and then try to contain it.”

Dr. Karmarkar reports no relevant financial relationships. Dr. Diekema reports research funding from bioMerieux and consulting fees from Opgen.

The CDC has reported two clusters of Candida auris infections resistant to all antifungal medications in long-term care facilities in 2021. Because these panresistant infections occurred without any exposure to antifungal drugs, the cases are even more worrisome. These clusters are the first time such nosocomial transmission has been detected.

In the District of Columbia, three panresistant isolates were discovered through screening for skin colonization with resistant organisms at a long-term acute care facility (LTAC) that cares for patients who are seriously ill, often on mechanical ventilation.

In Texas, the resistant organisms were found both by screening and in specimens from ill patients at an LTAC and a short-term acute care hospital that share patients. Two were panresistant, and five others were resistant to fluconazole and echinocandins.

These clusters occurred simultaneously and independently of each other; there were no links between the two institutions.

Colonization of skin with C. auris can lead to invasive infections in 5%-10% of affected patients. Routine skin surveillance cultures are not commonly done for Candida, although perirectal cultures for vancomycin-resistant enterococci and nasal swabs for MRSA have been done for years. Some areas, like Los Angeles, have recommended screening for C. auris in high-risk patients – defined as those who were on a ventilator or had a tracheostomy admitted from an LTAC or skilled nursing facility in Los Angeles County, New York, New Jersey, or Illinois.

In the past, about 85% of C. auris isolates in the United States have been resistant to azoles (for example, fluconazole), 33% to amphotericin B, and 1% to echinocandins. Because of generally strong susceptibility, an echinocandin such as micafungin or caspofungin has been the drug of choice for an invasive Candida infection.

C. auris is particularly difficult to deal with for several reasons. First, it can continue to live in the environment, on both dry or moist surfaces, for up to 2 weeks. Outbreaks have occurred both from hand (person-to-person) transmission or via inanimate surfaces that have become contaminated. Equally troublesome is that people become colonized with the yeast indefinitely.

Meghan Lyman, MD, of the fungal diseases branch of the CDC’s National Center for Emerging and Zoonotic Infectious Diseases, said in an interview that facilities might be slow in recognizing the problem and in identifying the organism. “We encounter problems in noninvasive specimens, especially urine,” Dr. Lyman added.

“Sometimes ... they consider Candida [to represent] colonization so they will often not speciate it.” She emphasized the need for facilities that care for ventilated patients to consider screening. “Higher priority ... are places in areas where there’s a lot of C. auris transmission or in nearby areas that are likely to get introductions.” Even those that do speciate may have difficulty identifying C. auris.

Further, Dr. Lyman stressed “the importance of antifungal susceptibility testing and testing for resistance. Because that’s also something that’s not widely available at all hospitals and clinical labs ... you can send it to the [CDC’s] antimicrobial resistance lab network” for testing.

COVID-19 has brought particular challenges. Rodney E. Rohde, PhD, MS, professor and chair, clinical lab science program, Texas State University, San Marcos, said in an interview that he is worried about all the steroids and broad-spectrum antibiotics patients receive.

They’re “being given medical interventions, whether it’s ventilators or [extracorporeal membrane oxygenation] or IVs or central lines or catheters for UTIs and you’re creating highways, right for something that may be right there,” said Dr. Rohde, who was not involved in the CDC study. “It’s a perfect storm, not just for C. auris, but I worry about bacterial resistance agents, too, like MRSA and so forth, having kind of a spike in those types of infections with COVID. So, it’s kind of a doubly dangerous time, I think.”

Multiresistant bacteria are a major health problem, causing illnesses in 2.8 million people annually in the United States, and causing about 35,000 deaths.

Dr. Rohde raised another, rarely mentioned concern. “We’re in crisis mode. People are leaving our field more than they ever had before. The medical laboratory is being decimated because people have burned out after these past 14 months. And so I worry just about competent medical laboratory professionals that are on board to deal with these types of other crises that are popping up within hospitals and long-term care facilities. It kind of keeps me awake.”

Dr. Rohde and Dr. Lyman shared their concern that COVID caused a decrease in screening for other infections and drug-resistant organisms. Bare-bones staffing and shortages of personal protective equipment have likely fueled the spread of these infections as well.

In an outbreak of C. auris in a Florida hospital’s COVID unit in 2020, 35 of 67 patients became colonized, and 6 became ill. The epidemiologists investigating thought that contaminated gowns or gloves, computers, and other equipment were likely sources of transmission.

Low pay, especially in nursing homes, is another problem Dr. Rohde mentioned. It’s an additional problem in both acute and long-term care that “some of the lowest-paid people are the environmental services people, and so the turnover is crazy.” Yet, we rely on them to keep everyone safe. He added that, in addition to pay, he “tries to give them the appreciation and the recognition that they really deserve.”

There are a few specific measures that can be taken to protect patients. Dr. Lyman concluded. “The best way is identifying cases and really ensuring good infection control to prevent the spread.” It’s back to basics – limiting broad-spectrum antibiotics and invasive medical devices, and especially good handwashing and thorough cleaning.

Dr. Lyman and Dr. Rohde have disclosed no relevant financial relationships.

Life-threatening fungal bloodstream infections associated with probiotic supplements have been reported in the journal Emerging Infectious Diseases by a group of researchers in Finland. While individuals consume these mixtures of bacteria and yeast in the hopes of “balancing” their microbiome or preventing diarrhea from antibiotic use, some died or developed yeast infections requiring prolonged antifungal treatment.

In a retrospective registry study at five university hospitals in Finland, the researchers found 46 patients between 2009 and 2018 with Saccharomyces sp. of yeast in their blood associated with ingesting probiotics. At least 20 (43%) had been using S. cerevisiae var. boulardii as a probiotic, with the organism then causing a bloodstream infection. Overall, 37% of the fungemic patients died.

Juha Rannikko, MD, lead author and infectious disease faculty member at Tampere University Hospital, Finland, said in an interview that there were an additional 1,153 nonblood isolates of Saccharomyces. He expressed surprise at the large number of nonblood isolates, saying: “If extrapolated ... it is about 10 nonblood Saccharomyces boulardii–associated findings for each Saccharomyces boulardii–associated fungemia.”

Most of the yeast infections (59%) occurred in patients with underlying gastrointestinal disease. Prior studies suggested that patients receiving enteral nutrition might become ill from translocation of the yeast from the inflamed GI tract.

If there were positive cultures for yeast from sites other than blood, physicians changed the antibiotics in 38% of patients.

Conventional wisdom has been that patients receiving broad-spectrum antibiotics should also receive an S. cerevisiae var. boulardii probiotic to prevent Clostridioides difficile infections. Dr. Rannikko and coauthors questioned this, noting results of such studies of prophylaxis were equivocal. “There is not enough evidence that clinicians should use Saccharomyces (probiotics) alongside antibiotics,” Dr. Rannikko concluded.

Laila Woc-Colburn, MD, associate professor at the Emory University School of Medicine, Atlanta, told this news organization that although the study was well done and was published in Emerging Infectious Diseases, the findings do not represent an “emerging” infectious disease. “We have known this for a while – since the 1990s,” she said. Warnings about probiotics are part of the standard advice Dr. Woc-Colburn gives transplant, chemotherapy, or immunosuppressed patients. “Don’t do these probiotics, because this is what’s going to happen,” she tells them. And she told this news organization, “If I see this in the blood, the first question I’m going to ask my patients is ... what probiotic were you drinking?”

Dr. Woc-Colburn said the Finnish researchers “did their due diligence” when conducting the study. “They were clear on their limitations. And they came out to the same conclusion as the 2005 Muñoz paper: That if we have some GI disruption, we should not be taking probiotics.”

She acknowledged that the Emerging Infectious Diseases study adds a substantial number of cases to those previously reported in the literature and confirms previous findings and recommendations to avoid probiotics if immunosuppressed or acutely ill.

Dr. Rannikko and Dr. Woc-Coburn have reported no relevant financial relationships. Dr. Rannikko has received a lecture fee from Novo Nordisk and a virtual congress attendance fee from Roche.

While individuals consume these mixtures of bacteria and yeast in the hopes of “balancing” their microbiome or preventing diarrhea from antibiotic use, some died or developed yeast infections requiring prolonged antifungal treatment.

In a retrospective registry study at five university hospitals in Finland, the researchers found 46 patients between 2009 and 2018 with Saccharomyces sp. of yeast in their blood associated with ingesting probiotics. At least 20 (43%) had been using S. cerevisiae var. boulardii as a probiotic, with the organism then causing a bloodstream infection. Overall, 37% of the fungemic patients died.

Juha Rannikko, MD, lead author and infectious disease faculty member at Tampere University Hospital, Finland, said in an interview that there were an additional 1,153 nonblood isolates of Saccharomyces. He expressed surprise at the large number of nonblood isolates, saying: “If extrapolated ... it is about 10 nonblood Saccharomyces boulardii–associated findings for each Saccharomyces boulardii–associated fungemia.”

Most of the yeast infections (59%) occurred in patients with underlying gastrointestinal disease. Prior studies suggested that patients receiving enteral nutrition might become ill from translocation of the yeast from the inflamed GI tract.

If there were positive cultures for yeast from sites other than blood, physicians changed the antibiotics in 38% of patients.

Conventional wisdom has been that patients receiving broad-spectrum antibiotics should also receive an S. cerevisiae var. boulardii probiotic to prevent Clostridioides difficile infections. Dr. Rannikko and coauthors questioned this, noting results of such studies of prophylaxis were equivocal. “There is not enough evidence that clinicians should use Saccharomyces (probiotics) alongside antibiotics,” Dr. Rannikko concluded.

Laila Woc-Colburn, MD, associate professor at the Emory University School of Medicine, Atlanta, told this news organization that although the study was well done and was published in Emerging Infectious Diseases, the findings do not represent an “emerging” infectious disease. “We have known this for a while – since the 1990s,” she said. Warnings about probiotics are part of the standard advice Dr. Woc-Colburn gives transplant, chemotherapy, or immunosuppressed patients. “Don’t do these probiotics, because this is what’s going to happen,” she tells them. And she told this news organization, “If I see this in the blood, the first question I’m going to ask my patients is ... what probiotic were you drinking?”

Dr. Woc-Colburn said the Finnish researchers “did their due diligence” when conducting the study. “They were clear on their limitations. And they came out to the same conclusion as the 2005 Muñoz paper: That if we have some GI disruption, we should not be taking probiotics.”

She acknowledged that the Emerging Infectious Diseases study adds a substantial number of cases to those previously reported in the literature and confirms previous findings and recommendations to avoid probiotics if immunosuppressed or acutely ill.

Dr. Rannikko and Dr. Woc-Coburn have reported no relevant financial relationships. Dr. Rannikko has received a lecture fee from Novo Nordisk and a virtual congress attendance fee from Roche.

The Food and Drug Administration has approved ibrexafungerp tablets (Brexafemme) as a 1-day oral therapy for vaginal yeast infections.

Ibrexafungerp is the first drug approved in a new antifungal class for vulvovaginal candidiasis (VVC) in more than 20 years, the drug’s manufacturer Scynexis said in a press release. It becomes the first and only nonazole treatment for vaginal yeast infections.

The biotechnology company said approval came after positive results from two phase 3 studies in which oral ibrexafungerp demonstrated efficacy and tolerability. The most common reactions observed in clinical trials were diarrhea, nausea, abdominal pain, dizziness, and vomiting.

There are few other treatments for vaginal yeast infections, which is the second most common cause of vaginitis. Those previously approved agents include several topical azole antifungals and oral fluconazole (Diflucan), which, Scynexis said, is the only other orally administered antifungal approved for the treatment of VVC in the United States and has  accounted for over more than 90% of prescriptions written for the condition each year.

However, the company noted, oral fluconazole reports a 55% therapeutic cure rate on its label, which now also includes warnings of potential fetal harm, demonstrating the need for new oral options.

The new drug may not fill that need for pregnant women, however, as the company noted that ibrexafungerp should not be used during pregnancy, and administration during pregnancy “may cause fetal harm based on animal studies.”

Because of possible teratogenic effects, the company advised clinicians to verify pregnancy status in females of reproductive potential before prescribing ibrexafungerp and advises effective contraception during treatment.

VVC can come with substantial morbidity, including genital pain, itching and burning, reduced sexual pleasure, and psychological distress.

David Angulo, MD, chief medical officer for Scynexis, said in a statement the tablets brings new benefits.

Dr. Angulo said the drug “has a differentiated fungicidal mechanism of action that kills a broad range of Candida species, including azole-resistant strains. We are working on completing our CANDLE study investigating ibrexafungerp for the prevention of recurrent VVC and expect we will be submitting a supplemental NDA [new drug application] in the first half of 2022.”

Scynexis said it partnered with Amplity Health, a Pennsylvania-based pharmaceutical company, to support U.S. marketing of the drug. The commercial launch will follow the approval.

Ibrexafungerp was granted approval through both the FDA’s Qualified Infectious Disease Product and Fast Track designations. It is expected to be marketed exclusively in the United States for 10 years.

One consequence of the ongoing opioid epidemic in the United States may be an increase in the number of hemorrhagic strokes caused by infective endocarditis, research suggests.

Intravenous drug use (IVDU) can cause this bacterial infection of the heart. In a single-center study, infective endocarditis was associated with an increase in the risk for hemorrhagic stroke as well as an increase in health care use and costs.

“Patients who are known IV drug users who have endocarditis should be more carefully screened for symptoms of cardiovascular disease,” Shahid M. Nimjee, MD, PhD, associate professor of neurosurgery and surgical director of the Comprehensive Stroke Center at the Ohio State University Wexner Medical Center, Columbus, said in a press release.

The findings were presented at the International Stroke Conference sponsored by the American Heart Association.

In the United States, 47,000 patients are treated in the hospital for endocarditis each year. Endocarditis increases the risk for stroke, which can entail significant morbidity and mortality, the authors noted.

IVDU is a risk factor for endocarditis. In the context of the opioid epidemic, Dr. Nimjee and colleagues sought to compare the risk for stroke among patients with endocarditis from IVDU with the risk among patients with endocarditis from other causes.

They retrospectively studied patients who had undergone treatment for infective endocarditis at Wexner Medical Center between Jan. 1, 2014, and July 1, 2018. They examined patients’ concomitant intravenous drug abuse and evaluated demographics, risk factors, and associated costs.
 

Dramatic increase

In all, 351 patients met the study’s inclusion criteria, and 170 (48%) had a history of IVDU-associated endocarditis. The incidence of patients with IVDU-associated endocarditis increased 630% from 2014 to 2018.

The prevalence of overall intracranial hemorrhage was increased among patients with IVDU, compared with those without (25.9% vs. 13.9%; P = .005).

This increase in prevalence included increases in intraparenchymal hemorrhage (12.4% vs. 5.1%; P = .012), subarachnoid hemorrhage (17.6% vs. 4.4%; P = .0001), and cerebral microbleeds (14.1% vs. 7.2%; P = .022).

IVDU also was associated with an increase in prevalence of infectious intracranial aneurysm (10.6% vs. 1.8%; P = .0001) and brain abscess (4.7% vs. 1.1%; P = .025).

Compared with patients with endocarditis from other causes, significantly higher numbers of patients with IVDU-associated endocarditis were homeless (5.9% vs. 1.1%; P = .014), uninsured (10.0% vs. 2.8%; P = .005), and unemployed (75.9% vs. 31.7%; P = .0001).

Medical costs were more than twice as high among patients with endocarditis from IVDU than among those with endocarditis from other causes. The difference in health care costs during admission per patient was more than $100,000.

“The wider societal impact of the opioid epidemic is not well understood,” Dr. Nimjee said in the press release. “Our research suggests that the impact of the opioid epidemic is far-reaching and contributes to increased costs in the criminal justice, health care systems, and the workplace. The increased costs can be particularly substantial for stroke care.”
 

Nationwide data desirable

“Past publications from the U.S. have shown an increase in incidence of IVDU-related endocarditis, and the current publication emphasizes this worrying trend,” Manuel Bolognese, MD, head of the stroke center at the Lucerne (Switzerland) Cantonal Hospital, said in an interview. “The higher degree of hemorrhagic strokes and brain abscesses as further complications is alarming as well and shows that IVDU-related endocarditis is becoming a more and more relevant medical problem in the U.S., with high morbidity and mortality.”

The study period is long enough to show a clear trend of increasing incidence of IVDU-related endocarditis, Dr. Bolognese said. The study’s biggest weaknesses are its retrospective design and restriction to a single center.

“Without knowing the prevalence of drug abuse and the socioeconomical situation in Columbus, it is difficult to generalize these findings to other regions in the U.S.A. or even abroad,” he said.

Also, the abstract does not provide some essential information, said Dr. Bolognese. It would be important to know which valve was affected in each patient, which bacteria were identified, whether patients also used nonopioid drugs, and what each patient’s immune status was.

A lack of sterile material such as syringes could explain the apparent association between IVDU-associated endocarditis and low socioeconomic status, said Dr. Bolognese. Delayed presentation to medical institutions because of a lack of insurance could have led to a more complicated course.

“It would be interesting to see numbers from a broader spectrum in a nationwide registry,” said Dr. Bolognese. “It might be worth studying interventions to improve the hygienic aspects (like supply of sterile material, especially in the most vulnerable groups, like homeless people) or to provide easier access to emergency health care despite lack of insurance, which could decrease the incidence of IVDU.”

Dr. Nimjee and Dr. Bolognese disclosed no relevant financial relationships.

Targeted prophylaxis with posaconazole was more effective than fluconazole in children with acute lymphoblastic leukemia who were undergoing induction chemotherapy in order to prevent invasive fungal infection, according to a study by Tian Zhang of Xidian University, Xi’an, China, and colleagues.

The researchers performed a single-center, retrospective cohort study of 155 patients with newly diagnosed acute lymphoblastic leukemia, comparing invasive fungal infections in those who received no prophylaxis (60 patients), posaconazole prophylaxis (70), or fluconazole prophylaxis (55) during induction therapy, according to a report published in the Journal of Microbiology, Immunology and Infection.

Proven and probable invasive fungal infections occurred during the induction phase in 45% in the no-prophylaxis group, in 18% of the posaconazole group and in 72% of the fluconazole group. Posaconazole prophylaxis reduced the odds of invasive fungal infections by greater than 60%, prolonged infection-free survival significantly, and did not increase the risk of hepatotoxicity.

In addition, the researchers found that the combination of age at diagnosis, clinically documented bacterial infection in the first 15 days of induction therapy, and absolute neutrophil count curve enabled significant prediction of the susceptibility to infections after receiving posaconazole prophylaxis.

“In general, these findings may serve as a basis for developing screening protocols to identify children who are at high risk for infection despite posaconazole prophylaxis so that early intervention can be initiated to mitigate fungal infections,” the researchers concluded.

The authors reported that they had no conflicts of interest.

Posaconazole prophylaxis reduced the odds of invasive fungal infections by greater than 60%, prolonged infection-free survival significantly, and did not increase the risk of hepatotoxicity.

In addition, the researchers found that the combination of age at diagnosis, clinically documented bacterial infection in the first 15 days of induction therapy, and absolute neutrophil count curve enabled significant prediction of the susceptibility to infections after receiving posaconazole prophylaxis.

“In general, these findings may serve as a basis for developing screening protocols to identify children who are at high risk for infection despite posaconazole prophylaxis so that early intervention can be initiated to mitigate fungal infections,” the researchers concluded.

The authors reported that they had no conflicts of interest.

Clinicians managing patients who have Candida bloodstream infection should consider an infectious disease (ID) consultation, findings from a large retrospective study suggest.

Mortality attributable to Candida bloodstream infection ranges between 15% and 47%, and delay in initiation of appropriate treatment has been associated with increased mortality. Previous small studies showed that ID consultation has conferred benefits to patients with Candida bloodstream infections. Carlos Mejia-Chew, MD, and colleagues from Washington University, St. Louis, sought to explore this further by performing a retrospective, single-center cohort study of 1,691 patients aged 18 years or older with Candida bloodstream infection from 2002 to 2015. They analyzed demographics, comorbidities, predisposing factors, all-cause mortality, antifungal use, central-line removal, and ophthalmological and echocardiographic evaluation in order to compare 90-day all-cause mortality between individuals with and without an ID consultation.

They found that those patients who received an ID consult for a Candida bloodstream infection had a significantly lower 90-day mortality rate than did those who did not (29% vs. 51%).

With a model using inverse weighting by the propensity score, they found that ID consultation was associated with a hazard ratio of 0.81 for mortality (95% confidence interval, 0.73-0.91; P less than .0001). In the ID consultation group, the median duration of antifungal therapy was significantly longer (18 vs. 14 days; P less than .0001); central-line removal was significantly more common (76% vs. 59%; P less than .0001); echocardiography use was more frequent (57% vs. 33%; P less than .0001); and ophthalmological examinations were performed more often (53% vs. 17%; P less than .0001). Importantly, fewer patients in the ID consultation group were untreated (2% vs. 14%; P less than .0001).

In an accompanying commentary, Katrien Lagrou, MD, and Eric Van Wijngaerden, MD, of the department of microbiology, immunology and transplantation, University Hospitals Leuven (Belgium) stated: “We think that the high proportion of patients (14%) with a Candida bloodstream infection who did not receive any antifungal treatment and did not have an infectious disease consultation is a particularly alarming finding. ... Ninety-day mortality in these untreated patients was high (67%).”

“We believe every hospital should have an expert management strategy addressing all individual cases of candidaemia. The need for such expert management should be incorporated in all future candidaemia management guidelines,” they concluded.

The study was funded by the Astellas Global Development Pharma, the Washington University Institute of Clinical and Translational Sciences, and the Agency for Healthcare Research and Quality. Several of the authors had financial connections to Astellas Global Development or other pharmaceutical companies. Dr. Lagrou and Dr. Van Wijngaerden both reported receiving personal fees and nonfinancial support from a number of pharmaceutical companies, but all outside the scope of the study.

MILAN – Skin manifestations of the vasculitides can point the way to an accurate diagnosis and provide clues about disease severity, Robert Micheletti, MD, said at the World Congress of Dermatology.

In granulomatous vasculitis, histiocytes and giant cells can play a significant role, explained Dr. Micheletti, director of the cutaneous vasculitis clinic at the University of Pennsylvania, Philadelphia. The condition may be secondary to an autoimmune disease such as lupus erythematosus or RA; a granulomatous disease such as Crohn’s disease or sarcoidosis; infections such as tuberculosis, a fungal disease, or herpes or zoster viruses, or lymphoma, Dr. Micheletti said.

However, a primary systemic vasculitis such as granulomatosis with polyangiitis (GPA; formerly known as Wegener’s polyangiitis) or eosinophilic granulomatosis with polyangiitis (EGPA; also known as Churg-Strauss vasculitis), giant cell arteritis, or Takayasu arteritis may also be responsible, he said. Occasionally, the culprit can also be a drug-induced vasculitis.

The physical examination gives clues to the size of involved vessels, which in turn helps to classify the vasculitis, Dr. Micheletti said.

When vasculitis affects small vessels, the skin findings will be palpable purpura, urticarial papules, vesicles, and petechiae, he said, adding that “The small vessel involvement accounts for the small size of the lesions, and complement cascade and inflammation account for the palpability of the lesions and the symptomatology.” As red blood cells extravasate from the affected vessels, nonblanching purpura develop, and gravity’s effect on the deposition of immune complex material dictates how lesions are distributed.

“Manifestations more typical of medium vessel vasculitis include subcutaneous nodules, livedo reticularis, retiform purpura, larger hemorrhagic bullae, and more significant ulceration and necrosis,” he said. “If such lesions are seen, suspect medium-vessel vasculitis or vasculitis overlapping small and medium vessels.” Cutaneous or systemic polyarteritis nodosa, antineutrophilic cytoplasmic autoantibody (ANCA)–associated vasculitis, and cryoglobulinemic vasculitis are examples, he added.

The particularities of renal manifestations of vasculitis also offer clues to the vessels involved. When a vasculitis patient has glomerulonephritis, suspect small-vessel involvement, Dr. Micheletti said. However, vasculitis affecting medium-sized vessels will cause renovascular hypertension and, potentially renal arterial aneurysms.

Nerves are typically spared in small-vessel vasculitis, while wrist or foot drop can be seen in mononeuritis multiplex.

Recently, the Diagnostic and Classification Criteria in Vasculitis Study (DCVAS) looked at more than 6,800 patients at over 130 sites around the world, proposing new classification criteria for ANCA-associated vasculitis (AAV) and large-vessel vasculitis. The study found that skin findings are common in AAV, with 30%-50% of cases presenting initially with skin lesions. Petechiae and/or purpura are the most common of the skin manifestations, he said. By contrast, for EGPA, allergic and nonspecific findings were the most common findings.

Although skin biopsy can confirm the diagnosis in up to 94% of AAV cases, it’s underutilized and performed in less than half (24%-44%) of cases, Dr. Micheletti said. The study’s findings “demonstrate the importance of a good skin exam, as well as its utility for diagnosis” of vasculitis, he said.

An additional finding form the DCVAS study was that skin lesions can give clues to severity of vasculitis: “Among 1,184 patients with ANCA-associated vasculitis, those with cutaneous involvement were more likely to have systemic manifestations of disease, more likely to have such severe manifestations as glomerulonephritis, alveolar hemorrhage, and mononeuritis,” said Dr. Micheletti, with a hazard ratio of 2.0 among those individuals who had EGPA or GPA.

“Skin findings have diagnostic and, potentially, prognostic importance,” he said. “Use the physician exam and your clinical acumen to your advantage,” but always confirm vasculitis with a biopsy. “Clinicopathologic correlation is key.” A simple urinalysis will screen for renal involvement, and is of “paramount importance,” he added.

Dr. Micheletti reported that he had no relevant disclosures.

WAIKOLOA, HAWAII – The work up of a case of onychomycosis doesn’t end with the detection of fungal hyphae.

Trichophyton rubrum remains the most common cause of toenail fungus in the United States, but nondermatophyte molds – Scopulariopsis, Fusarium, and others – are on the rise, so it’s important to speciate, especially when patients have atypical presentations or fail to respond to the T. rubrum go-to treatment, terbinafine, according to Nathaniel Jellinek, MD, of the department of dermatology, Brown University, Providence, R.I.

Standard in-office potassium hydroxide (KOH) testing can’t distinguish one species of fungus from another, nor can pathology with Gomori methenamine silver (GMS) or Periodic acid-Schiff (PAS) staining. Both culture and polymerase chain reaction (PCR), however, do.

Since few hospitals are equipped to run those tests, Dr. Jellinek uses the Case Western Center for Medical Mycology, in Cleveland, for testing.

In an interview at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation, Dr. Jellinek explained how to speciate, and the importance of doing so.

He also shared his tips on getting good nail clippings and good scrapings for debris for testing, and explained when KOH testing is enough – and when to opt for more advanced diagnostic methods, including PCR, which he said trumps all previous methods.

Terbinafine is still the best option for T. rubrum, but new topicals are better for nondermatophyte molds. There’s also a clever new dosing regimen for terbinafine, one that should put patients at ease about liver toxicity and other concerns. “If you tell them they’re getting 1 month off in the middle, it seems to go over a little easier,” Dr. Jellinek said.
