Black holes are associated with impaired cognition in MS

Article Type

Tue, 07/30/2019 - 14:29

In patients with multiple sclerosis (MS), black holes are associated with worse cognitive function, including processing speed and visuospatial memory, according to an investigation presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. Black holes are not associated with physical function, however. Evaluating black holes as part of routine clinical practice could be a quick method for screening people with MS for referral to a comprehensive cognitive assessment, said the authors.

Black holes (also known as T1-hypointense lesions) can be used as a marker of axonal loss and neuronal tissue destruction in patients with MS. Loss of axons and destruction of neuronal tissue contribute to cognitive and physical disability, but the literature contains few data about whether black holes correlate with cognitive and physical outcomes in MS.

Serkan Özakbas, MD, professor of neurology at Dokuz Eylül University in Izmir, Turkey, and colleagues examined 226 patients with MS to investigate this potential correlation. The population’s median Expanded Disability Status Scale score was 1.5. The researchers categorized participants into two groups according whether they had at least one black hole or not. They assessed patients’ cognitive function by administering the Brief International Cognitive Assessment for MS (BICAMS), which comprises the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test II (CVLT-II), and the Brief Visuospatial Memory Test–Revised (BVMTR). They evaluated participants’ physical function using the Timed 25-Foot Walk (T25FW), Nine-Hole Peg Test (9HPT), 6-Minute Walk Test (6MWT), Timed Up and Go (TUG), and 12-Item MS Walking Scale (MSWS-12).

In all, 116 (43.6%) participants had at least one black hole, and 150 (56.4%) had no black hole. Dr. Özakbas and colleagues found no significant difference between patients with and without black holes on the T25FW, 9HPT, 6MWT, TUG, MSWS-12, and CVLT-II. Patients without a black hole, however, had significantly higher SDMT (49.0 vs 42.9) and BVMTR (26.3 vs 23.3) scores, compared with those with at least one black hole.

“This study suggests that presence of black holes is related to cognitive function, but not to physical function,” the researchers concluded.

The investigators had no disclosures and conducted their study without financial support.

Functional GI disorders are common in MS

Article Type

Tue, 07/30/2019 - 14:34

 

Among patients with multiple sclerosis (MS), functional gastrointestinal (GI) disorders are prevalent and associated with health-related quality of life, according to research presented at the annual meeting of the Consortium of Multiple Sclerosis Centers. Managing patients’ psychiatric comorbidities could effectively reduce the burden of functional GI disorders, the researchers said.

Knowledge about the prevalence of functional GI disorders in the population of patients with MS is limited. For the most part, previous studies in this population have focused on irritable bowel syndrome (IBS). A 2013 study by Levinthal et al. (Mult Scler Int. 2013. doi: 10.1155/2013/319201) investigated the prevalence of other functional GI disorders in MS, but the literature contains little information about the clinical and demographic characteristics associated with these disorders. In addition, the extent to which comorbid functional GI disorders influence health-related quality of life in MS is also unknown.

Ruth Ann Marrie, MD, PhD, professor of neurology at the University of Manitoba in Winnipeg, and colleagues sought to determine the prevalence of functional bowel disorders, the demographic and clinical characteristics associated with functional bowel disorders, and the effects of these disorders on health-related quality of life in a large, diverse population of persons with MS. In 2014, the investigators used the Rome III questionnaire to survey participants in the North American Research Committee on MS (NARCOMS) registry about functional bowel disorders. Participants also provided information about their sociodemographic characteristics, their disability status (using Patient-Determined Disease Steps), and any comorbid depression or anxiety, their health behaviors, and their health-related quality of life (using the RAND-12).

Dr. Marrie and colleagues used these data to determine the prevalence of IBS, functional bloating, functional constipation, functional diarrhea, and functional dyspepsia. They used multivariable logistic regression models to examine the factors associated with any functional GI disorder, and they used linear regression to analyze the association between functional GI disorders and health-related quality of life using linear regression.

Dr. Marrie and colleagues identified 6,312 eligible respondents. Approximately 77% of the population was female, and the sample’s mean age was 58.3 years. In all, 2,647 respondents (42%) had a functional GI disorder. The most common was IBS, which affected 28.2% of participants. The prevalence of all functional GI disorders increased with increasing disability. Depression and anxiety were associated with increased odds of IBS and functional dyspepsia. After adjustment for sociodemographic and clinical characteristics, functional GI disorders were associated with lower physical and mental health-related quality of life.

The research was not supported by outside funding. Dr. Marrie had no disclosures, but other researchers had financial relationships with pharmaceutical companies, such as Merck, Novartis, Roche, Sanofi-Aventis, and Teva.

Neutrophils may decline in patients on fingolimod

Neutrophil levels may decline in patients with relapsing multiple sclerosis (MS) who have been on fingolimod for 2 or more years, according to an interim analysis of phase 4 study data.

Bruce Cree, MD, PhD, professor of neurology at UCSF Weill Institute for Neurosciences, University of California, San Francisco
Dr. Bruce Cree

A decrease in neutrophils over 6 months in a cohort of fingolimod treatment–experienced patients “was a surprise, at least to me,” said study investigator Bruce Cree, MD, PhD, professor of neurology at UCSF Weill Institute for Neurosciences, University of California, San Francisco. Why levels of these innate immune cells decreased in patients who had been on the drug for years “remains to be understood,” Dr. Cree said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “This is something that deserves further investigation ... to understand if that neutrophil count will continue to drop down over time or whether it ultimately plateaus.”

The decline in neutrophils in this cohort of patients continuously treated for at least 2 years was “only about 9%,” from an average of 3,698.56 cells per microliter at study baseline to 3,336.13 cells per microliter at 6 months.

Among fingolimod-naive patients who initiated treatment during the study, neutrophils decreased from 4,058.48 cells per microliter at baseline to 3,475.09 cells per microliter at 6 months, about 14%.

In the treatment-experienced patients, other immune cell subsets remained relatively stable over the 6-month period.

“If we are trying to understand the impact of fingolimod ultimately on propensity for development of opportunistic infection, of course we are focused almost exclusively on adaptive immunity,” Dr. Cree said. “But perhaps we are forgetting that innate immunity might be also extremely important for protecting ourselves against infection.”
 

The FLUENT study

Dr. Cree presented interim, 6-month data from the ongoing, open-label FLUENT study, which is a 12-month, prospective, multicenter, nonrandomized study to assess changes in the immune cell profiles of patients with relapsing MS who receive fingolimod. The study includes a cohort of treatment-experienced patients and a cohort of treatment-naive patients.

Fingolimod is a once-daily oral sphingosine 1–phosphate receptor modulator that prevents egress of lymphocytes from lymph nodes. Since its FDA approval in 2010, rare opportunistic infections, including progressive multifocal leukoencephalopathy (PML), have been reported in patients taking fingolimod.

Investigators did not assess changes in innate and adaptive components of the immune system during fingolimod treatment in the pivotal clinical trials, and the relationship between anti-JCV antibody index and immune cell subsets during fingolimod treatment is not known. Immunologic profiling may help gauge patients’ treatment response and risk of infection.

The FLUENT study’s primary outcome is change from baseline to month 6 in peripheral blood cellular components of the innate and adaptive immune system. Secondary endpoints include change in the immune cell subtype profile at months 3 and 12; anti-JCV antibody status at months 3, 6, and 12; change in anti-JCV antibody index at months 3, 6, and 12; and clinical variables. In addition, the investigators plan to examine changes in serum neurofilament light chain (NfL) levels at months 3, 6, and 12.

FLUENT includes a cohort of fingolimod-naive patients and a cohort of patients who have received continuous, commercially available fingolimod 0.5 mg/day for at least 2 years and plan to continue the drug during the 1-year study. The interim analysis included data from 166 fingolimod-naive patients (median age, 41 years; 77.7% female) and 216 fingolimod-experienced patients (median age, 50 years; 73.1% female). About 70% of patients in the fingolimod-naive cohort had had a relapse in the past 2 years, compared with about 22% of patients in the treatment-experienced cohort. Investigators began enrolling patients in September 2017.
 

 

 

Immune cell subsets

In the fingolimod-naive cohort, changes in immune cell subsets were expected and characteristic. Overall CD4+ count declined from baseline to month 6, and the decrease was “driven primarily by a decline in CD4+ naive T cells and CD4+ central memory T cells.” CD4+ effector memory cells, CD4+ Th1 cells, CD4+ Th2 cells, and CD4+ Th17 cells were less affected. “The effector cells do not have an expression of CCR7 [C-C chemokine receptor type 7] so they tend not to hone to the lymph nodes anyway,” Dr. Cree said.

CD8+ cells followed a similar pattern. “The overall count goes down, but perhaps not as much as with the CD4+ cells. The central memory and naive cells are affected a little bit more than the effector memory cells,” Dr. Cree said. “Then we see a comparable pattern with B cells. The absolute CD19+ counts go down. They’re driven by a decline in the naive cells. ... with less of a decline in memory cells and almost no decline in regulatory cells.”

Among innate immune cells, monocytes increased slightly, neutrophils declined, as expected, and natural killer cells declined slightly.

“When you turn your attention to ... those patients who have been on fingolimod, you do not see these changes for the lymphocytes,” Dr. Cree said. “Those lymphocytes are already sequestered, and we are really not seeing much of a change over time at all.”
 

A measure of CNS injury

In the treatment-naive cohort, serum neurofilament light chain (NfL) declined, but this measure did not change by much in the treatment-experienced cohort.

Among patients already on fingolimod, the serum NfL reduction “that would be anticipated as a therapeutic benefit from fingolimod is already being realized,” he said.

The serum NfL levels in the treatment-naive cohort at 6 months were similar to those of the treatment-experienced cohort at baseline, which indicates that “the impact of fingolimod in reducing circulating neurofilament – a marker of central nervous system injury – is seen within 6 months of treatment and likely persists as patients continue on fingolimod therapy,” Dr. Cree said.

Baseline anti-JCV antibody index was about the same for the treatment-naive and treatment-experienced cohorts (1.28 vs. 1.39, respectively), and this measure did not meaningfully change over 6 months in either cohort.
 

Adverse events

No new adverse events were identified in this interim analysis. Most common adverse events occurred more frequently in the treatment-naive cohort than in the treatment-experienced cohort, including headache (7.2% vs. 1.9%), upper respiratory tract infection (4.2% vs. 1.9%), pain in extremity (4.2% vs. 1.4%), lymphopenia (4.8% vs. 0.5%), anxiety (3.6% vs. 1.4%), fatigue (3.6% vs. 1.4%), nausea (3.0% vs. 0.9%), dizziness (3.0% vs. 0.5%), hypoesthesia (3.0% vs. 0.5%), and tremor (3.0% vs. 0%). An exception was falls, which occurred in 3.0% of the treatment-naive cohort and 4.6% of the treatment-experienced cohort.

Serious adverse events were about equal between the two groups (4.2% of the treatment-naive group and 5.1% of the treatment-experienced group), and adverse events leading to treatment discontinuation were more common in the fingolimod-naive cohort (10.2% vs. 5.6%).

Novartis funded the study, and four of the authors are Novartis employees. Dr. Cree disclosed consulting fees from Novartis and other pharmaceutical companies. His coauthors disclosed consulting fees, speaking fees, research support, and serving on advisory boards for pharmaceutical companies, including Novartis.

Most common adverse events occurred more frequently in the treatment-naive cohort than in the treatment-experienced cohort, including headache (7.2% vs. 1.9%), upper respiratory tract infection (4.2% vs. 1.9%), pain in extremity (4.2% vs. 1.4%), lymphopenia (4.8% vs. 0.5%), anxiety (3.6% vs. 1.4%), fatigue (3.6% vs. 1.4%), nausea (3.0% vs. 0.9%), dizziness (3.0% vs. 0.5%), hypoesthesia (3.0% vs. 0.5%), and tremor (3.0% vs. 0%). An exception was falls, which occurred in 3.0% of the treatment-naive cohort and 4.6% of the treatment-experienced cohort.

Serious adverse events were about equal between the two groups (4.2% of the treatment-naive group and 5.1% of the treatment-experienced group), and adverse events leading to treatment discontinuation were more common in the fingolimod-naive cohort (10.2% vs. 5.6%).

Neutrophil levels may decline in patients with relapsing multiple sclerosis (MS) who have been on fingolimod for 2 or more years, according to an interim analysis of phase 4 study data.

A decrease in neutrophils over 6 months in a cohort of fingolimod treatment–experienced patients “was a surprise, at least to me,” said study investigator Bruce Cree, MD, PhD, professor of neurology at UCSF Weill Institute for Neurosciences, University of California, San Francisco. Why levels of these innate immune cells decreased in patients who had been on the drug for years “remains to be understood,” Dr. Cree said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “This is something that deserves further investigation ... to understand if that neutrophil count will continue to drop down over time or whether it ultimately plateaus.”

The decline in neutrophils in this cohort of patients continuously treated for at least 2 years was “only about 9%,” from an average of 3,698.56 cells per microliter at study baseline to 3,336.13 cells per microliter at 6 months.

Among fingolimod-naive patients who initiated treatment during the study, neutrophils decreased from 4,058.48 cells per microliter at baseline to 3,475.09 cells per microliter at 6 months, about 14%.

In the treatment-experienced patients, other immune cell subsets remained relatively stable over the 6-month period.

“If we are trying to understand the impact of fingolimod ultimately on propensity for development of opportunistic infection, of course we are focused almost exclusively on adaptive immunity,” Dr. Cree said. “But perhaps we are forgetting that innate immunity might be also extremely important for protecting ourselves against infection.”
 

The FLUENT study

Dr. Cree presented interim, 6-month data from the ongoing, open-label FLUENT study, which is a 12-month, prospective, multicenter, nonrandomized study to assess changes in the immune cell profiles of patients with relapsing MS who receive fingolimod. The study includes a cohort of treatment-experienced patients and a cohort of treatment-naive patients.

Fingolimod is a once-daily oral sphingosine 1–phosphate receptor modulator that prevents egress of lymphocytes from lymph nodes. Since its FDA approval in 2010, rare opportunistic infections, including progressive multifocal leukoencephalopathy (PML), have been reported in patients taking fingolimod.

Investigators did not assess changes in innate and adaptive components of the immune system during fingolimod treatment in the pivotal clinical trials, and the relationship between anti-JCV antibody index and immune cell subsets during fingolimod treatment is not known. Immunologic profiling may help gauge patients’ treatment response and risk of infection.

The FLUENT study’s primary outcome is change from baseline to month 6 in peripheral blood cellular components of the innate and adaptive immune system. Secondary endpoints include change in the immune cell subtype profile at months 3 and 12; anti-JCV antibody status at months 3, 6, and 12; change in anti-JCV antibody index at months 3, 6, and 12; and clinical variables. In addition, the investigators plan to examine changes in serum neurofilament light chain (NfL) levels at months 3, 6, and 12.

FLUENT includes a cohort of fingolimod-naive patients and a cohort of patients who have received continuous, commercially available fingolimod 0.5 mg/day for at least 2 years and plan to continue the drug during the 1-year study. The interim analysis included data from 166 fingolimod-naive patients (median age, 41 years; 77.7% female) and 216 fingolimod-experienced patients (median age, 50 years; 73.1% female). About 70% of patients in the fingolimod-naive cohort had had a relapse in the past 2 years, compared with about 22% of patients in the treatment-experienced cohort. Investigators began enrolling patients in September 2017.
 

 

 

Immune cell subsets

In the fingolimod-naive cohort, changes in immune cell subsets were expected and characteristic. Overall CD4+ count declined from baseline to month 6, and the decrease was “driven primarily by a decline in CD4+ naive T cells and CD4+ central memory T cells.” CD4+ effector memory cells, CD4+ Th1 cells, CD4+ Th2 cells, and CD4+ Th17 cells were less affected. “The effector cells do not have an expression of CCR7 [C-C chemokine receptor type 7] so they tend not to hone to the lymph nodes anyway,” Dr. Cree said.

CD8+ cells followed a similar pattern. “The overall count goes down, but perhaps not as much as with the CD4+ cells. The central memory and naive cells are affected a little bit more than the effector memory cells,” Dr. Cree said. “Then we see a comparable pattern with B cells. The absolute CD19+ counts go down. They’re driven by a decline in the naive cells. ... with less of a decline in memory cells and almost no decline in regulatory cells.”

Among innate immune cells, monocytes increased slightly, neutrophils declined, as expected, and natural killer cells declined slightly.

“When you turn your attention to ... those patients who have been on fingolimod, you do not see these changes for the lymphocytes,” Dr. Cree said. “Those lymphocytes are already sequestered, and we are really not seeing much of a change over time at all.”
 

A measure of CNS injury

In the treatment-naive cohort, serum neurofilament light chain (NfL) declined, but this measure did not change by much in the treatment-experienced cohort.

Among patients already on fingolimod, the serum NfL reduction “that would be anticipated as a therapeutic benefit from fingolimod is already being realized,” he said.

The serum NfL levels in the treatment-naive cohort at 6 months were similar to those of the treatment-experienced cohort at baseline, which indicates that “the impact of fingolimod in reducing circulating neurofilament – a marker of central nervous system injury – is seen within 6 months of treatment and likely persists as patients continue on fingolimod therapy,” Dr. Cree said.

Baseline anti-JCV antibody index was about the same for the treatment-naive and treatment-experienced cohorts (1.28 vs. 1.39, respectively), and this measure did not meaningfully change over 6 months in either cohort.
 

Adverse events

No new adverse events were identified in this interim analysis. Most common adverse events occurred more frequently in the treatment-naive cohort than in the treatment-experienced cohort, including headache (7.2% vs. 1.9%), upper respiratory tract infection (4.2% vs. 1.9%), pain in extremity (4.2% vs. 1.4%), lymphopenia (4.8% vs. 0.5%), anxiety (3.6% vs. 1.4%), fatigue (3.6% vs. 1.4%), nausea (3.0% vs. 0.9%), dizziness (3.0% vs. 0.5%), hypoesthesia (3.0% vs. 0.5%), and tremor (3.0% vs. 0%). An exception was falls, which occurred in 3.0% of the treatment-naive cohort and 4.6% of the treatment-experienced cohort.

Serious adverse events were about equal between the two groups (4.2% of the treatment-naive group and 5.1% of the treatment-experienced group), and adverse events leading to treatment discontinuation were more common in the fingolimod-naive cohort (10.2% vs. 5.6%).

Treatment with 3.5 mg/kg of cladribine tablets effectively reduces relapse rate and the number of MRI lesions in patients with relapsing-remitting multiple sclerosis (MS), regardless of age. In addition, age does not affect the likelihood that a patient who receives cladribine will achieve no evidence of disease activity (NEDA), according to a study presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.

In the phase 3 CLARITY study, a cumulative dose of 3.5 mg/kg of cladribine over 2 years was associated with significantly reduced relapse rate and disability progression and improved MRI outcomes, compared with placebo. The drug’s efficacy persisted in patients who were switched to placebo in a 96-week extension study.
 

A post hoc analysis

A 2017 study by Weideman et al. suggested that disease-modifying treatment (DMT) is less effective in older patients. For this reason, Gavin Giovannoni, MBBCh, PhD, professor of neurology at Queen Mary University of London, and colleagues decided to investigate the effect of age on the efficacy of treatment with 3.5 mg/kg of cladribine. The investigators performed a post hoc analysis of the CLARITY and CLARITY extension studies of patients with relapsing-remitting MS. They categorized patients as older than 45 years or age 45 years or younger.

Patients enrolled in CLARITY were between ages 18 years and 65 years. They underwent MRI at pretrial assessment and at weeks 24, 48, and 96 or early termination. The investigators defined a qualifying relapse as one associated with changes in Kurtzke Functional Systems score and other specified clinical parameters. Qualifying relapses were confirmed by an independent evaluating physician who was blinded to treatment assignment.

In the CLARITY extension study, 98 participants who had received cladribine tablets 3.5 mg/kg in CLARITY were randomized to placebo for 2 additional years. Participants who continued on placebo in the CLARITY extension were evaluated according to age at entry into CLARITY.

Dr. Giovannoni and colleagues performed efficacy analyses for qualifying relapses; all relapses; and mean and cumulative numbers of new T1 gadolinium-enhancing lesions, active T2 lesions, and combined unique lesions. They defined NEDA as freedom from qualifying relapses, 6-month confirmed disability progression (as measured by the Expanded Disability Status Scale [EDSS] score), T1 gadolinium-enhancing lesions, and active T2 lesions. The investigators performed equivalent analyses for patients who received placebo in the CLARITY extension.
 

Age did not influence efficacy

Within each age group, participants in both treatment arms had similar baseline demographic and disease characteristics. In CLARITY, 221 patients were older than 45 years, and 649 were age 45 years or younger. In the CLARITY extension, 22 patients were older than 45 years, and 76 were age 45 years or younger. In CLARITY, but not the extension, the proportion of women was higher in the older group than in the younger group (77.7% vs. 66.1%). In CLARITY, patients aged 45 years or younger had a higher number of T1 gadolinium-enhancing lesions at baseline, compared with older patients.

 

 

At week 96 in CLARITY, the annual rate of qualifying relapses among patients older than 45 years was 0.14 for cladribine and 0.28 for placebo. Among patients aged 45 or younger, the annual rate of qualifying relapses was 0.15 for cladribine and 0.37 for placebo. For patients older than 45 years, the annual rate of all relapses was 0.28 for cladribine and 0.55 for placebo. For patients aged 45 years or younger, the annual rate of all relapses was 0.26 for cladribine and 0.65 for placebo. The treatment effect of cladribine, compared with placebo, on qualifying relapses and all relapses was similar for both age groups. In the CLARITY extension, the annualized relapse rate (ARR) was 0.17 in patients aged 45 years or younger and 0.05 in patients older than 45 years.

The mean number of new T1 gadolinium-enhancing lesions and cumulative new T1 gadolinium-enhancing lesions was reduced with cladribine, compared with placebo, in both age groups at week 96 in CLARITY. The mean number of active T2 lesions per patient per scan also was significantly reduced with cladribine, compared with placebo, in both age groups. The reduction was 0.167 in patients older than 45 years and 0.667 in patients aged 45 years and younger. In addition, the mean number of combined unique lesions per patient per scan also was significantly reduced with cladribine, compared with placebo, in both age groups. The reduction was 0.333 in patients older than 45 years and 0.667 in patients aged 45 years or younger.

The proportion of participants who achieved NEDA in CLARITY was 55.6% among patients older than 45 years who received cladribine, 39.6% among patients aged 45 years or younger who received cladribine, 28.2% among patients older than 45 years who received placebo, and 9.5% of patients aged 45 years or younger who received placebo. The odds ratio for achieving NEDA was significantly more favorable for the cladribine group, compared with the placebo group, in both age groups (3.19 for patients older than 45 years and 6.23 for patients aged 45 years or younger). In the CLARITY extension, the proportion of participants who achieved NEDA was 40.9% among patients older than 45 years and 28.2% among patients aged 45 years or younger.

“These data are consistent with previous analyses from CLARITY using a different age cutoff and with results from the overall study population,” said Dr. Giovannoni and colleagues.

Merck KGaA, which manufactures and markets cladribine, supported the study. Dr. Giovannoni and several of his coinvestigators have received speaker honoraria, consulting fees, or other funding from companies including Merck KGaA.

Patient registry sheds light on the economic impact of MS

Article Type

Fri, 06/11/2021 - 10:41

Preliminary findings from a registry questionnaire reveal that 77% of patients with multiple sclerosis (MS) are employed either full or part time, with the rest being unemployed.

“MS seems to prevent people with MS from realizing their full potential at work or home,” said study coauthor Kottil Rammohan, MD, who summarized the study results in a video interview. Dr. Rammohan is professor of clinical neurology, director of the MS center of excellence, and chief of the multiple sclerosis division at the University of Miami. The study findings were presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.

The North American Registry for Care and Research in Multiple Sclerosis (NARCRMS) prospectively collects information about the health care economics of patients with MS and its effects on daily life. In 2017, NARCRMS established the health care economics outcomes research (HEOR) advisory group. NARCRMS developed a Health-Related Productivity Questionnaire and Health Resource Utilization Questionnaire. The questionnaires were incorporated into the existing case report forms that are completed by patients at enrollment, annual, and exacerbation visits.

This analysis was based on 480 patients who had completed HEOR case report forms. Among those, 77% are employed either full or part time; however, of those 15% were underemployed, meaning they wanted to work more than their current work levels. About 13% are on disability.


“What we found was there was a significant impact at home as well,” said Dr. Rammohan. Patients reported that MS kept them from completing household chores. “MS is a disease that seems to impact not only the work environment, but also the home environment.”

When polled to determine the main reason why these MS patients are not able to function, “what we found was that it was not because of gait or immobility, it was difficulty related to fatigue,” Dr. Rammohan said. The second most common impairment was related to cognition.

“These are what we call the silent or the transparent symptoms of MS.”

Dr. Rammohan disclosed consulting fees from EMD Serono, Biogen, Sanofi-Aventis, Genzyme, Novartis, Teva Neurosciences, Acorda, and Roche/Genentech.

“MS seems to prevent people with MS from realizing their full potential at work or home,” said study coauthor Kottil Rammohan, MD, who summarized the study results in a video interview. Dr. Rammohan is professor of clinical neurology, director of the MS center of excellence, and chief of the multiple sclerosis division at the University of Miami. The study findings were presented at the annual meeting of the Consortium of Multiple Sclerosis Centers.

The North American Registry for Care and Research in Multiple Sclerosis (NARCRMS) prospectively collects information about the health care economics of patients with MS and its effects on daily life. In 2017, NARCRMS established the health care economics outcomes research (HEOR) advisory group. NARCRMS developed a Health-Related Productivity Questionnaire and Health Resource Utilization Questionnaire. The questionnaires were incorporated into the existing case report forms that are completed by patients at enrollment, annual, and exacerbation visits.

This analysis was based on 480 patients who had completed HEOR case report forms. Among those, 77% are employed either full or part time; however, of those 15% were underemployed, meaning they wanted to work more than their current work levels. About 13% are on disability.


“What we found was there was a significant impact at home as well,” said Dr. Rammohan. Patients reported that MS kept them from completing household chores. “MS is a disease that seems to impact not only the work environment, but also the home environment.”

When polled to determine the main reason why these MS patients are not able to function, “what we found was that it was not because of gait or immobility, it was difficulty related to fatigue,” Dr. Rammohan said. The second most common impairment was related to cognition.

“These are what we call the silent or the transparent symptoms of MS.”

In MS, the challenges for women are unique

The one constant in multiple sclerosis (MS) is its lack of constancy. “As our lives are dynamic and change over time, MS is also dynamic and changes over time.” This is especially the case in women, noted Mitzi Joi Williams, MD.

About three in four people with MS are female – about 750,000 in the United States. And the risk and incidence may be highest in African American women.

In a presentation about the unique needs of women with MS, Dr. Williams, an assistant professor of internal medicine at the Morehouse School of Medicine in Atlanta, offered these tips at the annual meeting of the Consortium of Multiple Sclerosis Centers.

Pay attention to sexual dysfunction

Patients with MS often are ashamed to talk about sexual dysfunction, Dr. Williams said, but it is on many minds. “If I have a program on intimacy in MS, people are out the door.”

She urged colleagues to understand that MS can affect sexuality through three routes: primary, secondary, and tertiary dysfunction.

In primary sexual dysfunction, brain and spinal lesions directly related to MS can cause problems such as lack of sensation or abnormal sensations, decreased libido, vaginal dryness, and difficult orgasm.

Secondary sexual dysfunction refers to problems caused by symptoms of MS such as fatigue, which can worsen as the day progresses and affect nighttime intimacy, she said. Bladder dysfunction is another sensitive area in sexuality, with patients – especially women – “concerned that they will lose control of their bladder or they have already lost control.”

Cognitive dysfunction also can disrupt sexual function. “It is important to focus, and certain things cannot happen if you do not. If you are not able to focus and concentrate, it can affect interest,” Dr. Williams said.

Additionally, medications can improve some symptoms while making others worse. For example, a drug may relieve spasticity but boost fatigue. “We have to walk this tightrope,” she said. “But if we are not asking our patients, they may not volunteer this information.”

Finally, she said, MS can spark tertiary sexual dysfunction – poor body image, depression, anxiety, and disruptive changes in familial roles. For example, one partner may become a caregiver, and “it is hard to go from caregiving to sexy time.”

“It is something we have to acknowledge and find ways to deal with,” Dr. Williams said.

To address these issues, she pointed to strategies for symptomatic relief and disease-modifying therapy (DMT) and pinpointed several treatment options.

  • Fatigue – stimulants, diet, exercise.
  • Spasticity – muscle relaxants, exercise.
  • Bladder dysfunction – fluid restriction, medication.
  • Paresthesia – antidepressants, anticonvulsants.
  • Numbness – vibrators, devices to increase stimulation.

Sexual therapy, couples therapy, and pelvic floor physical therapy also can be helpful.

Be aware of special needs during prepregnancy and pregnancy

“MS itself does not have a lot of effects on fertility, pregnancy, or pregnancy outcomes,” Dr. Williams said. However, “medications cause concern about how we manage pregnancy and fertility.”

In vitro fertilization may increase the risk of relapse, she added, and patients on dimethyl fumarate who experience vomiting or diarrhea may not be able to properly absorb oral contraceptives.

Women with MS may not need to go off DMT when they are trying to conceive, she said. “If patients have very aggressive disease, they may need to be on DMT through conception, through the first trimester, and even the entire pregnancy to prevent long-term disability.”

What about pregnancy itself? “An MS diagnosis alone does not mean that a pregnancy is high risk,” she said. “There are not necessarily additional tests and ultrasounds that are recommended for our patients based on MS diagnosis alone.”

Treatment discontinuation may be warranted during pregnancy, when MS generally improves. However, some MS symptoms – fatigue, bladder dysfunction, and balance – may increase. Corticosteroids can be appropriate if relapses occur during pregnancy.

Menopause and MS symptoms may overlap

Symptoms such as hot flashes, mood changes, sleep disturbance, bladder dysfunction, and decreased energy may be signs of MS, or they could indicate menopause, Dr. Williams said. “Sometimes patients come in and they are getting worse, and we look into it and discover they are premenopausal.”

A decline in estrogen during menopause may worsen MS symptoms, she added, and hormone therapy may be appropriate. A phase 2 study found a benefit in menopausal patients with MS for estriol in conjunction with a DMT, but more studies are needed.

Dr. Williams reported no relevant financial disclosures.

In MS, children aren’t just little adults

– Multiple sclerosis (MS) presents quite differently in children than adults, a neurologist told colleagues, but many treatments are the same. The key is to remember the unique needs of pediatric MS patients, their specific challenges, and the difference that can be made through therapy.

“We need to treat them when they’re young, perhaps, to prevent disability later on,” said Jennifer Graves, MD, PhD, director of neuroimmunology research at the University of California, San Diego, and director of the Rady Children’s Pediatric MS Clinic.

Fortunately, “they tend to respond to any DMT [disease-modifying therapy] you give them,” said Dr. Graves, who spoke at the annual meeting of the Consortium of Multiple Sclerosis Centers.

Unlike the adult version, pediatric MS is almost never progressive, she said, and the relapsing form affects 85%-99% of those with the condition.

And children with MS suffer from high relapse rates. “In some of the more recent studies, the annual relapse rates have been two to even five to six times higher than in adults,” she related.

For acute relapses, Dr. Graves recommends IV methylprednisolone as a first-line treatment. High-dose oral steroids can be appropriate in teenagers, and plasma exchange is a second-line option.

DMT does work in children. “They’re just so inflammatory, having so much activity, that they tend to respond to anything,” she noted.

With few exceptions, DMTs have been tested in children, she said. But the trials in children have tended to be small, and only fingolimod (Gilenya) is Food and Drug Administration–approved for pediatric patients (aged 10-18 years).

What’s the best DMT for kids? “There is evidence that the higher-potency drugs may work better in some patients,” Dr. Graves said. “I diagnosed a 4 year old with MS. With an annual relapse rate of 6, I had no hesitancy about jumping to the highest-potency agent I had available.”

She cautioned, however, that there may never be deep insight into the best choices because of it is not feasible to study all the available DMTs in children.

Dr. Graves offered these tips about treating children with MS:

  • Be prepared to spend long periods educating children and their parents. “You think you spend a long time with your adult patients? Double it,” she said. “Most new patient appointments will be 90 minutes at least. Negotiate that time for the patients in your clinic who are very young.”
  • Don’t separate kids from parents. “I discourage parents from asking their children to leave the room. Everyone should know what the choices are as much as possible and having the children on the same page can help with compliance,” Dr. Graves said.
  • Consider unique safety considerations. “Children are less likely to be JC [John Cunningham] virus antibody-positive than adults, and we can feel more confident with agents that cause PML [progressive multifocal leukoencephalopathy],” she said. “But they’re more likely to convert on our watch.”
  • Consider mentioning sexual function to teens. As adolescents, “they’re unsure of sexual function to begin with, and they often don’t know if they’re normal in terms of sexual function.” Don’t forget that contraceptives may be appropriate because some MS drugs are teratogenic. “Have a lengthy and realistic conversation about birth control,” Dr. Graves said, “and maybe ask the parents to leave the room.”

Dr. Graves disclosed receiving speaking honoraria from Novartis and Sanofi Genzyme, and grants from Biogen and Genentech.

Balancing privacy, protection in at-risk MS patients

Article Type
Changed
Mon, 07/01/2019 - 11:26

Finding a balance between maintaining patient privacy and preventing self-harm is crucial in multiple sclerosis patients at risk for suicide.

“There are some situations where concern for a patient’s safety overrides [confidentiality],” Lauren Sankary, an attorney and neuroethics fellow at the Cleveland Clinic, said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “I want to empower you to feel confident to break confidentiality when it makes sense based on your professional judgment.”

It’s not clear whether suicide is more common in patients with MS. A systematic review from 2012 found that most studies reviewed documented a higher rate of suicide in patients with MS, compared with the general population (J Psychosom Res. 2012 Dec;73(6):411-7) while a report from 2017 noted that rates of suicidal intent were elevated in MS (Mult Scler. 2017 Jun;23(7):923-927). Conversely, a French study from 2017 found that excess suicide risk may not be true for MS patients (Mult Scler. 2017 May;23(6):864-871).

When considering breaking confidentiality to seek help for a patient, Ms. Sankary said, “the ethical tension is that on the one hand, disclosing protected health information may protect patient safety. But on the other hand, it may threaten the therapeutic relationship. It’s a true ethical dilemma, and part of what’s difficult is figuring out in which situations are we willing to accept these tradeoffs.”

Consider professional ethical guidelines, federal and local laws, and clinical protocols in the decision making process, she advised.

On the federal level, HIPAA allows the breaking of confidentiality when it “is necessary to prevent or lessen a serious and imminent threat to the health or safety of a person or the public.”

The U.S. Department of Health & Human Services’ Office of Civil Rights notes that “HIPAA permits a covered health care provider to notify a patient’s family members of a serious and imminent threat to the health or safety of the patient or others if those family members are in a position to lessen or avert the threat. Thus, to the extent that a provider determines that there is a serious and imminent threat of a patient physically harming self or others, HIPAA would permit the provider to warn the appropriate person(s) of the threat, consistent with his or her professional ethical obligations and State law requirements.”

Confidential information cannot be disclosed to just anyone, however. HIPAA notes that it must be disclosed only to “a person or persons reasonably able to prevent or lessen the threat, including the target of the threat.”

HIPAA doesn’t require medical professionals to report suicide risk, Ms. Sankary said, but some states require certain professionals to do so. And some states require certain professionals to alert parents if children are suicidal.

The laws mainly affect mental health professionals but may extend to physicians and nurses, according to the National Conference of State Legislators. For example, New Jersey professionals in several fields have a duty to warn in certain situations, including the risk of self-harm.

The American Medical Association’s Code of Medical Ethics suggests physicians must “inform the patient when there has been a significant infringement on privacy of which the patient would otherwise not be aware,” Ms. Sankary said.

Ms. Sankary reported no relevant disclosures.

“There are some situations where concern for a patient’s safety overrides [confidentiality],” Lauren Sankary, an attorney and neuroethics fellow at the Cleveland Clinic, said at the annual meeting of the Consortium of Multiple Sclerosis Centers. “I want to empower you to feel confident to break confidentiality when it makes sense based on your professional judgment.”

It’s not clear whether suicide is more common in patients with MS. A systematic review from 2012 found that most studies reviewed documented a higher rate of suicide in patients with MS, compared with the general population (J Psychosom Res. 2012 Dec;73(6):411-7) while a report from 2017 noted that rates of suicidal intent were elevated in MS (Mult Scler. 2017 Jun;23(7):923-927). Conversely, a French study from 2017 found that excess suicide risk may not be true for MS patients (Mult Scler. 2017 May;23(6):864-871).

When considering breaking confidentiality to seek help for a patient, Ms. Sankary said, “the ethical tension is that on the one hand, disclosing protected health information may protect patient safety. But on the other hand, it may threaten the therapeutic relationship. It’s a true ethical dilemma, and part of what’s difficult is figuring out in which situations are we willing to accept these tradeoffs.”

Consider professional ethical guidelines, federal and local laws, and clinical protocols in the decision making process, she advised.

On the federal level, HIPAA allows the breaking of confidentiality when it “is necessary to prevent or lessen a serious and imminent threat to the health or safety of a person or the public.”

The U.S. Department of Health & Human Services’ Office of Civil Rights notes that “HIPAA permits a covered health care provider to notify a patient’s family members of a serious and imminent threat to the health or safety of the patient or others if those family members are in a position to lessen or avert the threat. Thus, to the extent that a provider determines that there is a serious and imminent threat of a patient physically harming self or others, HIPAA would permit the provider to warn the appropriate person(s) of the threat, consistent with his or her professional ethical obligations and State law requirements.”

Confidential information cannot be disclosed to just anyone, however. HIPAA notes that it must be disclosed only to “a person or persons reasonably able to prevent or lessen the threat, including the target of the threat.”

HIPAA doesn’t require medical professionals to report suicide risk, Ms. Sankary said, but some states require certain professionals to do so. And some states require certain professionals to alert parents if children are suicidal.

The laws mainly affect mental health professionals but may extend to physicians and nurses, according to the National Conference of State Legislators. For example, New Jersey professionals in several fields have a duty to warn in certain situations, including the risk of self-harm.

The American Medical Association’s Code of Medical Ethics suggests physicians must “inform the patient when there has been a significant infringement on privacy of which the patient would otherwise not be aware,” Ms. Sankary said.

Ms. Sankary reported no relevant disclosures.

Pediatric MS often goes untreated in the year after diagnosis

About 65% of patients with pediatric multiple sclerosis (MS) do not receive disease-modifying therapy (DMT) within 1 year of diagnosis, according to an analysis of insurance claims data. Females may be more likely than males to receive DMT during this time, said Chinmay Deshpande, PhD, at the annual meeting of the Consortium of Multiple Sclerosis Centers.

Pediatric onset of MS occurs in 3-5% of patients with the disease, and the median age of pediatric onset is 15 years. This population tends to have a high relapse rate and may develop disability at a younger age, said Dr. Deshpande, associate director of health economics and outcomes research at Novartis. “There have been very few studies done on this population, especially in the clinical trial setting. ... Physicians face considerable uncertainty in how to treat these patients.”
 

Observational data

To assess the proportion of patients with pediatric MS who receive DMT in the year after diagnosis, Dr. Deshpande and colleagues analyzed retrospective observational data from the Truven Health Marketscan Commercial and Encounters administrative claims databases. They studied patients who received an MS diagnosis between Jan. 1, 2010, and Dec. 31, 2016. In addition, they examined which DMTs were used as first-line therapies, whether prescribing patterns changed between 2010 and 2017, and time to treatment discontinuation or switch.

The databases included data from more than 182,000 patients with two or more claims of MS diagnosis. After including only patients age 17 years or younger at the index diagnosis date who had insurance during the 6 months prior to the index date and 12 months after the index date and who did not use DMT during the 6 months prior to the index date, 288 patients remained in the analysis. Patients had an average age of about 14 years.

The primary outcome was the proportion of patients who started DMT in the year after MS diagnosis. “The proportion of untreated patients within their first year of diagnosis was around 65%,” said Dr. Deshpande. On average, treated patients were slightly older than untreated patients (15.0 years vs. 13.3 years). Among treated patients, 75% were female, and 25% were male. Overall, however, 61% were female and 39% were male. The difference in treatment by gender was surprising and the reason for it is not understood, Dr. Deshpande said. One possibility is that the difference relates to earlier maturation in females, but that is only a hypothesis, he said.

Glatiramer acetate and interferon beta-1a were first-line DMTs for 48% and 30.6% of the treated patients, respectively. Dimethyl fumarate (7.1%), natalizumab (5.1%), fingolimod (4.1%), interferon beta-1b (4.1%), and peginterferon beta-1a (1%) also were used as first-line therapy.

Twenty percent of patients who received DMT switched to another medication during the follow-up period. The median time of switching was within 6 months of starting first-line therapy. Most patients who discontinued DMT – that is, they did not have any DMT for 60 days after stopping their first DMT – did so within 10 months of diagnosis.
 

Use of newer medications

Overall, the use of glatiramer acetate and interferons has decreased over time, and while the use of newer DMTs has increased, the trend is not consistent. “With the growing uptake of newer oral and infusible DMTs over the recent years, there is a need to increase treatment awareness in the pediatric MS population and to inform currently approved treatment options to the prescribers,” Dr. Deshpande and colleagues said.

The claims database is generalizable and nationally representative, but it does not include clinical or MRI data. “It’s hard to understand the reasoning why they discontinued or why they are switching,” Dr. Deshpande said. In addition, the sample size was relatively small, and the results should be interpreted accordingly, he said.

Novartis funded the study, and Dr. Deshpande and a coauthor are employees of Novartis. Other coauthors reported consulting fees from Novartis, as well as consulting fees and grant funding from other pharmaceutical companies.
