PHILADELPHIA – The association between vitamin D insufficiency and multiple sclerosis (MS) outcome in children with acquired demyelinating syndromes (ADS) partly relates to skin pigmentation, according to research described at the annual meeting of the American Academy of Neurology. Future research will be required to understand the interactions between dietary vitamin D ingestion, sun exposure, pigmentation of sun-exposed skin, seasonal vitamin D concentrations, and the genetic influences of vitamin D pathways with MS risk.

Race, vitamin D status, HLA-DRB1*15 genotype, and place of residence during childhood all affect the risk of MS. The place of residence also can affect exposure to ultraviolet radiation and, thus, dermal pigmentation.

Candice Dunn, a clinical research coordinator at the Children’s Hospital of Philadelphia, and colleagues conducted a prospective study to determine whether HLA-DRB1*15 status, 25-hydroxyvitamin D (25[OH]D) levels measured at baseline, and skin tone are associated with MS outcome in children with ADS. They enrolled 259 children with incident ADS in a multisite study in Toronto and Philadelphia (latitudes 43° to 51°). The investigators measured non–sun-exposed upper inner arm melanin content using the DSM II ColorMeter device. They measured 25(OH)D concentrations in serum obtained within 60 days of symptom onset and compared them with laboratory-reported normative values. Vitamin D insufficiency was defined as 25(OH)D less than 75 nmol/L. Ms. Dunn and colleagues quantified HLA-DRB1*15 alleles using allele-specific polymerase chain reaction amplification. Statistical analysis was performed using Spearman correlation models and Wilcoxon or Kruskal-Wallis tests as appropriate.

In all, 68 children were diagnosed with MS, 191 remained monophasic (monoADS). Approximately 46% of children with MS were HLA-DRB1*15-positive, compared with 29.9% of monoADS children. In addition, children with MS had significantly lower 25(OH)D levels (mean, 45.4 nmol/L) than monoADS children (mean, 61.9 nmol/L) at baseline. Non–sun-exposed skin tone measured in the upper inner arm did not differ between children diagnosed with MS (mean melanin index, 46.4) and monoADS (mean melanin index, 43.5). Furthermore, 25(OH)D levels correlated with upper inner arm melanin index in the MS group, but not in children with monoADS.

Ms. Dunn had nothing to disclose, but various coauthors have received compensation from companies such as Novartis, Merck, Teva, Celgene, and Genentech.

The Food and Drug Administration has approved tafamidis meglumine (Vyndaqel) and tafamidis (Vyndamax) for the treatment of heart disease caused by transthyretin-mediated amyloidosis.

The disease is caused by the buildup of abnormal deposits of amyloid in the body’s organs and tissues, interfering with normal function, and most often occurs in the heart and nervous system. Symptoms associated with amyloid buildup in the heart include shortness of breath, fatigue, heart failure, loss of consciousness, abnormal heart rhythms, and death.

FDA approval of both drugs was based on results of a clinical trial in which 441 patients with transthyretin-mediated amyloidosis received either tafamidis meglumine or placebo. After a mean of 30 months, patients who received tafamidis meglumine had a higher survival rate and a lower number of cardiovascular-related hospitalizations than did patients in the placebo group.

No drug-associated side effects have yet been identified; however, tafamidis can cause fetal harm when administered to a pregnant woman.

“Transthyretin-mediated amyloidosis is a rare, debilitating, and often fatal disease. The treatments we’re approving today are an important advancement in the treatment of the cardiomyopathy caused by transthyretin-mediated amyloidosis,” said Norman Stockbridge, MD, PhD, director of the Division of Cardiovascular and Renal Drugs in the FDA’s Center for Drug Evaluation and Research.

Many veterans of the Gulf War are experiencing deployment-related chronic illness, known as Gulf War illness (GWI). Symptoms of GWI include cognitive impairments (mood and memory), chronic fatigue, musculoskeletal pain, gastrointestinal (GI) disorders, respiratory problems, and skin rashes.^1-4 Three survey studies of the physical and mental health of a large cohort of Gulf War and Gulf era veterans, conducted by the US Department of Veterans Affairs (VA) Office of Public Health, established the increased prevalence of GWI in the decades that followed the end of the conflict.^5-7 Thus, GWI has become the signature adverse health-related outcome of the Gulf War. Quality improvement (QI) within the Veterans Health Administration (VHA) is needed in the diagnosis and treatment of GWI.

Background

GWI was first termed chronic multisymptom illness (CMI) by the Centers for Disease Control and Prevention (CDC). According to the CDC-10 case definition, CMI in veterans of the 1990-1991 Gulf War is defined as having ≥ 1 symptoms lasting ≥ 6 months in at least 2 of 3 categories: fatigue, depressed mood and altered cognition, and musculoskeletal pain.³ The Kansas case definition of GWI is more specific and is defined as having moderate-to-severe symptoms that are unexplained by any other diagnosis, in at least 3 of 6 categories: fatigue/sleep, somatic pain, neurologic/cognition/mood, GI, respiratory, and skin.⁴ Although chronic unexplained symptoms have occurred after other modern conflicts, the prevalence of GWI among Gulf War veterans has proven higher than those of prior conflicts.⁸

The Persian Gulf War Veterans Act of 1998 and the Veterans Programs Enhancement Act of 1998 mandated studies by the Institute of Medicine (IOM) on the biologic and chemical exposures that may have contributed to illness in the Kuwaiti theater of operations.⁹ However, elucidating the etiology and underlying pathophysiology of GWI has been a major research challenge. In the absence of objective diagnostic measures, an understanding of the fundamental pathophysiology, evidence-based treatments, a single case definition, and definitive guidelines for health care providers (HCPs) for the diagnosis and management of GWI has not been produced. As a result, veterans with GWI have struggled for nearly 3 decades to find a consistent diagnosis of and an effective treatment for their condition.

According to a report by the Government Accountability Office (GAO), the VA approved only 17% of claims for compensation for veterans with GWI from 2011 to 2015, about one-third the level of approval for all other claimed disabilities.¹⁰ Although the VA applied GAO recommendations to improve the compensation process, many veterans consider that their illness is treated as psychosomatic in clinical practice, despite emerging evidence of GWI-associated biomarkers.¹¹ Others think they have been forgotten due to their short 1-year period of service in the Gulf War.¹² To realign research, guidelines, clinical care, and the health care experience of veterans with GWI, focused QI within VHA is urgently needed.

Veterans of Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND) are experiencing similar CMI symptoms. A study of US Army Reserve OEF/OIF veterans found that > 60% met the CDC-10 case definition for GWI 1-year postdeployment.¹³ Thus, CMI is emerging as a serious health problem for post-9/11 veterans. The evidence of postdeployment CMI among veterans of recent conflicts underscores the need to increase efforts at a national level, beginning with the VHA. This report includes a summary of Gulf War veterans’ experiences at the Minneapolis VA Health Care System (MVAHCS) and a proposal for QI of MVAHCS processes focused on HCP education and clinical care.

Methods

To determine areas of GWI health care that needed QI at the MVAHCS, veterans with GWI were contacted for a telephone survey. These veterans had participated in the Gulf War Illness Inflammation Reduction Trial (ClinicalTrials.gov. Identifier: NCT02506192). Therefore, all met the Kansas case definition for GWI.⁴ The aim of the survey was to characterize veterans’ experiences seeking health care for chronic postdeployment symptoms.

Sixty Gulf War veterans were contacted by telephone and invited to participate in a 15-minute survey about their experience seeking diagnosis and treatment for GWI. They were informed that the survey was voluntary and confidential, that it was not part of the research trial in which they had been enrolled, and that their participation would not affect compensation received from VA. Verbal consent was requested, and 30 veterans agreed to participate in the survey.

The survey included questions about the course of illness, disability and service connection status, HCPs seen, and suggestions for improvement in their care (Table 1). 

Results

Of the 30 veterans who participated in the survey, most were male with only 2 female veterans. This proportion of female veterans (7%) is similar to the overall percentage of female veterans (6.7%) of the first Gulf War.² Ages ranged from 46 to 66 years with a mean age of 53. Mean duration of illness, defined as time elapsed since perceived onset of chronic systemic symptoms during or after deployment, was 22.8 years, with a range of 4 to 27 years. Most respondents reported symptom onset within a few years after the end of the conflict, while a few reported the onset within weeks of arriving in the Kuwaiti theater of operations. A little more than half the respondents considered themselves disabled due to their symptoms, while one-third reported losing the ability to work due to symptoms. Respondents described needing to reduce hours, retire early, or stop working altogether because of their symptoms.

Respondents attributed several common chronic symptoms to deployment in the Gulf Wars (Table 2). 

Most veterans surveyed were service connected for individual chronic symptoms. Some were service connected for systemic conditions such as fibromyalgia (FM), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS) (5 veterans were connected for each condition). Three of the 30 veterans had been diagnosed with GWI—2 by past VA physicians and 1 by a physician at a GWI research center in another state. Of those 3, only 1 was service connected for the condition. Three respondents were not service connected at all.

The most common VA HCPs seen were in primary care and neurology followed by psychiatry and psychology. Of non-VA HCPs, most respondents saw primary care providers (PCPs) followed by chiropractors (Table 4).

Before taking the Gulf War survey, a broad subjective question was posed. Respondents were asked whether VA HCPs were “supportive as you sought care for chronic postdeployment symptoms.” A majority of veterans reported that their VA HCPs were supportive. Reasons veterans gave for VA HCPs lack of support included feeling that HCPs did not believe them or trust their reported symptoms; did not care about their symptoms; refused to attribute their symptoms to Gulf War deployment; attributed symptoms to mental health issues; focused on doing things a certain way; or did not have the tools or information necessary to help.

Most non-VA HCPs were supportive. Reasons community HCPs were not supportive included “not looking at the whole picture,” not knowing veteran issues, not feeling comfortable with GWI, or not having much they could do.

Veterans were then asked whether they felt their HCPs were knowledgeable about GWI, and 13 respondents reported that their HCP was knowledgeable. Reasons respondents felt VA HCPs were not knowledgeable included denying that GWI exists, attributing symptoms to other conditions, not being aware of or familiar with GWI, needing education from the veteran, avoiding discussion about GWI or not caring to learn, or not knowing the latest research evidence to talk about GWI with authority. Compared with VA HCPs, veterans found community HCPs about half as likely to be knowledgeable about GWI. Many reported that community HCPs had not heard of GWI or had no knowledge about it.

Respondents also were asked what types of treatments they tried in order to typify the care received. The most common responses were pain medications, symptom-specific treatments, or “just putting up with it” (no treatment). Many patients were also self-medicating, trying lifestyle changes, or seeking alternative therapies.

Finally, respondents were asked on a scale of 0 (very unsatisfied) to 5 (very satisfied), how satisfied they were with their overall care at the VA. The majority were satisfied with their overall care, with two-thirds very satisfied (5 of 5) or pretty satisfied (4 of 5). Only 3 (10%) were unsatisfied or very unsatisfied. Respondents had the following comments about their care: “They treat me like I am important;” “I am very thankful even though they cannot figure it out;” “They are doing the best they can with no answers and not enough help;” “[I know] it is still a work in progress.” A number of respondents were satisfied with some HCPs or care for some but not all of their symptoms. Reasons respondents were less satisfied included desiring answers, feeling they were not respected, or feeling that their concerns were not addressed.

When asked for suggestions for improvement of GWI care, the most common response was providing up-to-date HCP education (Table 5).

Discussion

The veterans participating in this QI survey had similar demographics, symptomology, and exposures as did those in other studies.^1-7 Therefore, improvements based on their responses are likely applicable to the health care of veterans experiencing GWI-associated symptoms at other VA health care systems as well.

Veterans with GWI can lose significant functional capacity and productivity due to their symptoms. The symptoms are chronic and have afflicted many Gulf War veterans for nearly 3 decades. Furthermore, the prevalence of GWI in Gulf War veterans continues to increase.^5-7 These facts testify to the enormous health-related quality-of-life impact of GWI.

Veterans who meet the Kansas case definition for GWI were not diagnosed or service connected in a uniform manner. Only 3 of the 30 veterans in this study were given a unifying diagnosis that connected their chronic illness to Gulf War deployment. Under current guidelines, Gulf War veterans are able to receive compensation for chronic symptoms in 3 ways: (1) compensation for chronic unexplained symptoms existing for ≥ 6 months that appeared during active duty in the Southwest Asia theater or by December 31, 2021, and are ≥ 10% disabling; (2) the 1995 Persian Gulf War Veterans’ Act recognizes 3 multisymptom illnesses for which veterans can be service connected: FM, CFS, and functional GI disorders, including IBS; and (3) expansion to include any CMI of unknown etiology is underway. A uniform diagnostic protocol based on biomarkers and updated understanding of disease pathology would be helpful.

Respondents shared experiences that demonstrated perceived gaps in HCP support or knowledge. Overall, more respondents found their HCPs supportive. Many of the reasons respondents found HCPs unsupportive related to acknowledgment of symptoms. Also, more respondents found that both VA and non-VA HCPs lacked knowledge about GWI symptoms. These findings further highlight the need for HCP education within the VA and in community-based care.

The treatments tried by respondents also highlight potential areas for improvement. Most of the treatments were for pain; therefore, more involvement with pain clinics and specialists could be helpful. Symptom-specific medications also are appropriate, although only one-third of patients reported use. While medications are not necessarily markers of quality care, the fact that many patients self-medicate or go without treatment suggests that access to care could be improved. In 2014, the VA and the US Department of Defense (DoD) released the “VA/DoD Clinical Practice Guideline for the Management of Chronic Multisymptom Illness,” which recommended treatments for the global disease and specific symptoms.¹⁵

Since then, GWI research points to inflammatory and metabolic disease mechanisms.^11-14,16 As the underlying pathophysiology is further elucidated, practice guidelines will need to be updated to include anti-inflammatory and antioxidant treatments used in practice for GWI and similar chronic systemic illnesses (eg, CFS, FM, and IBS).^17-19

Randomized control trials are needed to determine the efficacy of such medications for the treatment of GWI. As new results emerge, disseminating and updating evidence-based guidelines in a coordinated manner will be required for veterans to receive appropriate treatment. Veterans also seek alternative or nonpharmaceutical interventions, such as physical therapy and diet changes. Improving access to integrative medicine, physical therapy, nutritionists, and other practitioners also could optimize veterans’ health and function.

HCP Education

The Gulf War veteran respondents who participated in the survey noted HCP education, research progress, and veteran inclusion as areas for improvement. Respondents requested dissemination of information on diagnosis and treatment of GWI for HCPs and updates on research and other actions. They suggested ways research could be more effective (such as subgrouping by exposure, which researchers have been doing) and could extend to veterans experiencing CMI from other conflicts as well.²⁰ Respondents also recommended team approaches or centers of excellence in order to receive more comprehensive care.

An asset of VHA is the culture of QI and education. The VA Employee Education System previously produced “Caring for Gulf War I Veterans,” a systemwide training module.²¹ In 2014, updated clinical practice guidelines for GWI were provided by the VA and the DoD, including evidence for each recommendation. In 2016, the VA in collaboration with the IOM produced a report summarizing conclusions and recommendations regarding associations between health concerns and Gulf War deployment.²² A concise guide for HCPs caring for veterans with GWI, updated in 2018, is available.²³ Updated treatment guidelines, based on evolving understanding of GWI pathophysiology, and continuing efforts to disseminate information will be essential.

Respondents most often presented to primary care, both within and outside of MVAHCS. Therefore, VA and community PCPs who see veterans should be equipped to recognize and diagnose GWI as well as be familiar with basic disease management and specialists whom they could refer their patients. Neurology was the second most common specialty seen by respondents. The most prominent symptoms of GWI are related to nervous system function in addition to evidence of underlying neuroinflammation.²⁰ Veterans may present to a neurologist with a variety of concerns, such as cognitive issues, sleep problems, migraines and headaches, and pain. Neurologists could best manage treatments targeting common neurologic GWI symptoms and neuroinflammation, especially as new treatments are discovered.

The next 2 most common specialty services seen were psychiatry and psychology (7 responses for each). Five respondents reported mental health issues as part of their chronic postdeployment symptoms. Population-based studies have indicated that rates of PTSD in Gulf War veterans is 3% to 6%, much lower than the prevalence of GWI.^8,20 The 2010 IOM study concluded that GWI symptoms cannot be ascribed to any known psychiatric disorder. Unfortunately, several surveyed veterans made it clear that they had been denied care due to HCPs attributing their symptoms solely to mental health issues. Therefore, psychiatrists and psychologists must be educated about GWI, mental health issues occurring in Gulf War veterans, and physiologic symptoms of GWI that may mimic or coincide with mental health issues. These HCPs also would be important to include in an interdisciplinary clinic for veterans with GWI.

Finally, respondents sought care from numerous other specialties, including gastroenterology, physical therapy, pulmonology, dermatology, and surgical subspecialties, such as orthopedics and otolaryngology. This wide range of specialists seen emphasizes the need for medical education, beginning in medical school. If provided education on GWI, these specialists would be able to treat veterans with GWI, know to look for updates on GWI management, or know to look for other common symptoms, such as chronic sinusitis in otolaryngology or recurring rashes in dermatology. We also recommend identifying HCPs in these specialties who could be part of an interdisciplinary clinic or be referrals for symptom management.

Protocol Implementation

HCP education and clinical care protocol implementation should be the initial focus of improving GWI management. A team of stakeholders within the different areas of MVAHCS, including education, HCPs, and administrative staff, will need to be developed. Reaching out to VA HCPs who have seen veterans with GWI will be an essential first step to equip them with updated education about the diagnosis and management of CMI. Providing integrated widespread education to current HCPs who are likely to encounter veterans with deployment-related CMI from the Gulf War, OND/OEF/OIF, or other deployments also will be necessary. Finally, educating medical trainees, including residents and medical students, will ensure continuous care for future veterans, post-9/11 veterans.

GWI presentations at medical grand rounds or at other medical community educational events could provide educational outlets. These events create face-to-face opportunities to discuss GWI/CMI education with HCPs, giving them the opportunity to offer feedback about their experiences and create relationships with other HCPs who have seen patients with GWI/CMI. At an educational event, a short postevent feedback form that indicates whether HCPs would like more information or get involved in a clinic for veterans with CMI could be included. This information would help identify key HCPs and areas within the local VA needing further improvements, such as creating a clinic for veterans with GWI.

Since 1946, the VA has worked with academic institutions to provide state-of-the-art health care to US veterans and train new HCPs to meet the health care needs of the nation. Every year, > 40,000 residents and 20,000 medical students receive medical training at VA facilities, making VA the largest single provider of medical education in the country. Therefore, providing detailed GWI/CMI education to medical students and residents as a standard part of the VA Talent Management System would be of value for all VA professionals.

GWI Clinics

Access to comprehensive care can be accomplished by organizing a clinic for veterans with GWI. The most likely effective location would be in primary care. PCPs who have seen veterans with GWI and/or expressed interest in learning more about GWI will be the initial point of contact. As the primary care service has connections to ancillary services, such as pharmacists, dieticians, psychologists, and social workers, organizing 1 day each week to see patients with GWI would improve care.

As the need for specialty care arises, the team also would need to identify specialists willing to receive referrals from HCPs of veterans with GWI. These specialists could be identified via feedback forms from educational events, surveys after an online educational training, or through relationships among VA physicians. As the clinic becomes established, it may be effective to have certain commonly seen specialists available in person, most likely neurology, psychiatry, gastroenterology, pulmonology, and dermatology. Also, relationships with a pain clinic, sleep medicine, and integrative medicine services should be established.

Measures of improvement in the veteran health care experience could include veterans’ perceptions of the supportiveness and knowledge of physicians about GWI as well as overall satisfaction. A follow-up survey on these measures of veterans involved in a GWI clinic and those not involved would be a way to determine whether these clinics better meet veterans’ needs and what additional QI is needed.

Conclusion

A significant number of Gulf War veterans experience chronic postdeployment symptoms that need to be better addressed. Physicians need to be equipped to recognize and manage GWI and similar postdeployment CMI among veterans of OEF/OIF/OND. We recommend creating an educational initiative about GWI among VA physicians and trainees, connecting physicians who see veterans with GWI, and establishing an interdisciplinary clinic with a referral system as the next steps to improve care for veterans. An additional goal would be to reach out to veteran networks to update them on GWI research, education, and available health care, as veterans are the essential stakeholders in the QI process.

Many veterans of the Gulf War are experiencing deployment-related chronic illness, known as Gulf War illness (GWI). Symptoms of GWI include cognitive impairments (mood and memory), chronic fatigue, musculoskeletal pain, gastrointestinal (GI) disorders, respiratory problems, and skin rashes.^1-4 Three survey studies of the physical and mental health of a large cohort of Gulf War and Gulf era veterans, conducted by the US Department of Veterans Affairs (VA) Office of Public Health, established the increased prevalence of GWI in the decades that followed the end of the conflict.^5-7 Thus, GWI has become the signature adverse health-related outcome of the Gulf War.

To determine areas of GWI health care that needed QI at the MVAHCS, veterans with GWI were contacted for a telephone survey. These veterans had participated in the Gulf War Illness Inflammation Reduction Trial (ClinicalTrials.gov. Identifier: NCT02506192). Therefore, all met the Kansas case definition for GWI.⁴ The aim of the survey was to characterize veterans’ experiences seeking health care for chronic postdeployment symptoms.

Sixty Gulf War veterans were contacted by telephone and invited to participate in a 15-minute survey about their experience seeking diagnosis and treatment for GWI. They were informed that the survey was voluntary and confidential, that it was not part of the research trial in which they had been enrolled, and that their participation would not affect compensation received from VA. Verbal consent was requested, and 30 veterans agreed to participate in the survey.

The survey included questions about the course of illness, disability and service connection status, HCPs seen, and suggestions for improvement in their care (Table 1). 

Results

Of the 30 veterans who participated in the survey, most were male with only 2 female veterans. This proportion of female veterans (7%) is similar to the overall percentage of female veterans (6.7%) of the first Gulf War.² Ages ranged from 46 to 66 years with a mean age of 53. Mean duration of illness, defined as time elapsed since perceived onset of chronic systemic symptoms during or after deployment, was 22.8 years, with a range of 4 to 27 years. Most respondents reported symptom onset within a few years after the end of the conflict, while a few reported the onset within weeks of arriving in the Kuwaiti theater of operations. A little more than half the respondents considered themselves disabled due to their symptoms, while one-third reported losing the ability to work due to symptoms. Respondents described needing to reduce hours, retire early, or stop working altogether because of their symptoms.

Respondents attributed several common chronic symptoms to deployment in the Gulf Wars (Table 2). 

Most veterans surveyed were service connected for individual chronic symptoms. Some were service connected for systemic conditions such as fibromyalgia (FM), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS) (5 veterans were connected for each condition). Three of the 30 veterans had been diagnosed with GWI—2 by past VA physicians and 1 by a physician at a GWI research center in another state. Of those 3, only 1 was service connected for the condition. Three respondents were not service connected at all.

The most common VA HCPs seen were in primary care and neurology followed by psychiatry and psychology. Of non-VA HCPs, most respondents saw primary care providers (PCPs) followed by chiropractors (Table 4).

Before taking the Gulf War survey, a broad subjective question was posed. Respondents were asked whether VA HCPs were “supportive as you sought care for chronic postdeployment symptoms.” A majority of veterans reported that their VA HCPs were supportive. Reasons veterans gave for VA HCPs lack of support included feeling that HCPs did not believe them or trust their reported symptoms; did not care about their symptoms; refused to attribute their symptoms to Gulf War deployment; attributed symptoms to mental health issues; focused on doing things a certain way; or did not have the tools or information necessary to help.

Most non-VA HCPs were supportive. Reasons community HCPs were not supportive included “not looking at the whole picture,” not knowing veteran issues, not feeling comfortable with GWI, or not having much they could do.

Veterans were then asked whether they felt their HCPs were knowledgeable about GWI, and 13 respondents reported that their HCP was knowledgeable. Reasons respondents felt VA HCPs were not knowledgeable included denying that GWI exists, attributing symptoms to other conditions, not being aware of or familiar with GWI, needing education from the veteran, avoiding discussion about GWI or not caring to learn, or not knowing the latest research evidence to talk about GWI with authority. Compared with VA HCPs, veterans found community HCPs about half as likely to be knowledgeable about GWI. Many reported that community HCPs had not heard of GWI or had no knowledge about it.

Respondents also were asked what types of treatments they tried in order to typify the care received. The most common responses were pain medications, symptom-specific treatments, or “just putting up with it” (no treatment). Many patients were also self-medicating, trying lifestyle changes, or seeking alternative therapies.

Finally, respondents were asked on a scale of 0 (very unsatisfied) to 5 (very satisfied), how satisfied they were with their overall care at the VA. The majority were satisfied with their overall care, with two-thirds very satisfied (5 of 5) or pretty satisfied (4 of 5). Only 3 (10%) were unsatisfied or very unsatisfied. Respondents had the following comments about their care: “They treat me like I am important;” “I am very thankful even though they cannot figure it out;” “They are doing the best they can with no answers and not enough help;” “[I know] it is still a work in progress.” A number of respondents were satisfied with some HCPs or care for some but not all of their symptoms. Reasons respondents were less satisfied included desiring answers, feeling they were not respected, or feeling that their concerns were not addressed.

When asked for suggestions for improvement of GWI care, the most common response was providing up-to-date HCP education (Table 5).

Discussion

The veterans participating in this QI survey had similar demographics, symptomology, and exposures as did those in other studies.^1-7 Therefore, improvements based on their responses are likely applicable to the health care of veterans experiencing GWI-associated symptoms at other VA health care systems as well.

Veterans with GWI can lose significant functional capacity and productivity due to their symptoms. The symptoms are chronic and have afflicted many Gulf War veterans for nearly 3 decades. Furthermore, the prevalence of GWI in Gulf War veterans continues to increase.^5-7 These facts testify to the enormous health-related quality-of-life impact of GWI.

Veterans who meet the Kansas case definition for GWI were not diagnosed or service connected in a uniform manner. Only 3 of the 30 veterans in this study were given a unifying diagnosis that connected their chronic illness to Gulf War deployment. Under current guidelines, Gulf War veterans are able to receive compensation for chronic symptoms in 3 ways: (1) compensation for chronic unexplained symptoms existing for ≥ 6 months that appeared during active duty in the Southwest Asia theater or by December 31, 2021, and are ≥ 10% disabling; (2) the 1995 Persian Gulf War Veterans’ Act recognizes 3 multisymptom illnesses for which veterans can be service connected: FM, CFS, and functional GI disorders, including IBS; and (3) expansion to include any CMI of unknown etiology is underway. A uniform diagnostic protocol based on biomarkers and updated understanding of disease pathology would be helpful.

Respondents shared experiences that demonstrated perceived gaps in HCP support or knowledge. Overall, more respondents found their HCPs supportive. Many of the reasons respondents found HCPs unsupportive related to acknowledgment of symptoms. Also, more respondents found that both VA and non-VA HCPs lacked knowledge about GWI symptoms. These findings further highlight the need for HCP education within the VA and in community-based care.

The treatments tried by respondents also highlight potential areas for improvement. Most of the treatments were for pain; therefore, more involvement with pain clinics and specialists could be helpful. Symptom-specific medications also are appropriate, although only one-third of patients reported use. While medications are not necessarily markers of quality care, the fact that many patients self-medicate or go without treatment suggests that access to care could be improved. In 2014, the VA and the US Department of Defense (DoD) released the “VA/DoD Clinical Practice Guideline for the Management of Chronic Multisymptom Illness,” which recommended treatments for the global disease and specific symptoms.¹⁵

Since then, GWI research points to inflammatory and metabolic disease mechanisms.^11-14,16 As the underlying pathophysiology is further elucidated, practice guidelines will need to be updated to include anti-inflammatory and antioxidant treatments used in practice for GWI and similar chronic systemic illnesses (eg, CFS, FM, and IBS).^17-19

Randomized control trials are needed to determine the efficacy of such medications for the treatment of GWI. As new results emerge, disseminating and updating evidence-based guidelines in a coordinated manner will be required for veterans to receive appropriate treatment. Veterans also seek alternative or nonpharmaceutical interventions, such as physical therapy and diet changes. Improving access to integrative medicine, physical therapy, nutritionists, and other practitioners also could optimize veterans’ health and function.

HCP Education

The Gulf War veteran respondents who participated in the survey noted HCP education, research progress, and veteran inclusion as areas for improvement. Respondents requested dissemination of information on diagnosis and treatment of GWI for HCPs and updates on research and other actions. They suggested ways research could be more effective (such as subgrouping by exposure, which researchers have been doing) and could extend to veterans experiencing CMI from other conflicts as well.²⁰ Respondents also recommended team approaches or centers of excellence in order to receive more comprehensive care.

An asset of VHA is the culture of QI and education. The VA Employee Education System previously produced “Caring for Gulf War I Veterans,” a systemwide training module.²¹ In 2014, updated clinical practice guidelines for GWI were provided by the VA and the DoD, including evidence for each recommendation. In 2016, the VA in collaboration with the IOM produced a report summarizing conclusions and recommendations regarding associations between health concerns and Gulf War deployment.²² A concise guide for HCPs caring for veterans with GWI, updated in 2018, is available.²³ Updated treatment guidelines, based on evolving understanding of GWI pathophysiology, and continuing efforts to disseminate information will be essential.

Respondents most often presented to primary care, both within and outside of MVAHCS. Therefore, VA and community PCPs who see veterans should be equipped to recognize and diagnose GWI as well as be familiar with basic disease management and specialists whom they could refer their patients. Neurology was the second most common specialty seen by respondents. The most prominent symptoms of GWI are related to nervous system function in addition to evidence of underlying neuroinflammation.²⁰ Veterans may present to a neurologist with a variety of concerns, such as cognitive issues, sleep problems, migraines and headaches, and pain. Neurologists could best manage treatments targeting common neurologic GWI symptoms and neuroinflammation, especially as new treatments are discovered.

The next 2 most common specialty services seen were psychiatry and psychology (7 responses for each). Five respondents reported mental health issues as part of their chronic postdeployment symptoms. Population-based studies have indicated that rates of PTSD in Gulf War veterans is 3% to 6%, much lower than the prevalence of GWI.^8,20 The 2010 IOM study concluded that GWI symptoms cannot be ascribed to any known psychiatric disorder. Unfortunately, several surveyed veterans made it clear that they had been denied care due to HCPs attributing their symptoms solely to mental health issues. Therefore, psychiatrists and psychologists must be educated about GWI, mental health issues occurring in Gulf War veterans, and physiologic symptoms of GWI that may mimic or coincide with mental health issues. These HCPs also would be important to include in an interdisciplinary clinic for veterans with GWI.

Finally, respondents sought care from numerous other specialties, including gastroenterology, physical therapy, pulmonology, dermatology, and surgical subspecialties, such as orthopedics and otolaryngology. This wide range of specialists seen emphasizes the need for medical education, beginning in medical school. If provided education on GWI, these specialists would be able to treat veterans with GWI, know to look for updates on GWI management, or know to look for other common symptoms, such as chronic sinusitis in otolaryngology or recurring rashes in dermatology. We also recommend identifying HCPs in these specialties who could be part of an interdisciplinary clinic or be referrals for symptom management.

Protocol Implementation

HCP education and clinical care protocol implementation should be the initial focus of improving GWI management. A team of stakeholders within the different areas of MVAHCS, including education, HCPs, and administrative staff, will need to be developed. Reaching out to VA HCPs who have seen veterans with GWI will be an essential first step to equip them with updated education about the diagnosis and management of CMI. Providing integrated widespread education to current HCPs who are likely to encounter veterans with deployment-related CMI from the Gulf War, OND/OEF/OIF, or other deployments also will be necessary. Finally, educating medical trainees, including residents and medical students, will ensure continuous care for future veterans, post-9/11 veterans.

GWI presentations at medical grand rounds or at other medical community educational events could provide educational outlets. These events create face-to-face opportunities to discuss GWI/CMI education with HCPs, giving them the opportunity to offer feedback about their experiences and create relationships with other HCPs who have seen patients with GWI/CMI. At an educational event, a short postevent feedback form that indicates whether HCPs would like more information or get involved in a clinic for veterans with CMI could be included. This information would help identify key HCPs and areas within the local VA needing further improvements, such as creating a clinic for veterans with GWI.

Since 1946, the VA has worked with academic institutions to provide state-of-the-art health care to US veterans and train new HCPs to meet the health care needs of the nation. Every year, > 40,000 residents and 20,000 medical students receive medical training at VA facilities, making VA the largest single provider of medical education in the country. Therefore, providing detailed GWI/CMI education to medical students and residents as a standard part of the VA Talent Management System would be of value for all VA professionals.

GWI Clinics

Access to comprehensive care can be accomplished by organizing a clinic for veterans with GWI. The most likely effective location would be in primary care. PCPs who have seen veterans with GWI and/or expressed interest in learning more about GWI will be the initial point of contact. As the primary care service has connections to ancillary services, such as pharmacists, dieticians, psychologists, and social workers, organizing 1 day each week to see patients with GWI would improve care.

As the need for specialty care arises, the team also would need to identify specialists willing to receive referrals from HCPs of veterans with GWI. These specialists could be identified via feedback forms from educational events, surveys after an online educational training, or through relationships among VA physicians. As the clinic becomes established, it may be effective to have certain commonly seen specialists available in person, most likely neurology, psychiatry, gastroenterology, pulmonology, and dermatology. Also, relationships with a pain clinic, sleep medicine, and integrative medicine services should be established.

Measures of improvement in the veteran health care experience could include veterans’ perceptions of the supportiveness and knowledge of physicians about GWI as well as overall satisfaction. A follow-up survey on these measures of veterans involved in a GWI clinic and those not involved would be a way to determine whether these clinics better meet veterans’ needs and what additional QI is needed.

Conclusion

A significant number of Gulf War veterans experience chronic postdeployment symptoms that need to be better addressed. Physicians need to be equipped to recognize and manage GWI and similar postdeployment CMI among veterans of OEF/OIF/OND. We recommend creating an educational initiative about GWI among VA physicians and trainees, connecting physicians who see veterans with GWI, and establishing an interdisciplinary clinic with a referral system as the next steps to improve care for veterans. An additional goal would be to reach out to veteran networks to update them on GWI research, education, and available health care, as veterans are the essential stakeholders in the QI process.

Many veterans of the Gulf War are experiencing deployment-related chronic illness, known as Gulf War illness (GWI). Symptoms of GWI include cognitive impairments (mood and memory), chronic fatigue, musculoskeletal pain, gastrointestinal (GI) disorders, respiratory problems, and skin rashes.^1-4 Three survey studies of the physical and mental health of a large cohort of Gulf War and Gulf era veterans, conducted by the US Department of Veterans Affairs (VA) Office of Public Health, established the increased prevalence of GWI in the decades that followed the end of the conflict.^5-7 Thus, GWI has become the signature adverse health-related outcome of the Gulf War. Quality improvement (QI) within the Veterans Health Administration (VHA) is needed in the diagnosis and treatment of GWI.

Background

GWI was first termed chronic multisymptom illness (CMI) by the Centers for Disease Control and Prevention (CDC). According to the CDC-10 case definition, CMI in veterans of the 1990-1991 Gulf War is defined as having ≥ 1 symptoms lasting ≥ 6 months in at least 2 of 3 categories: fatigue, depressed mood and altered cognition, and musculoskeletal pain.³ The Kansas case definition of GWI is more specific and is defined as having moderate-to-severe symptoms that are unexplained by any other diagnosis, in at least 3 of 6 categories: fatigue/sleep, somatic pain, neurologic/cognition/mood, GI, respiratory, and skin.⁴ Although chronic unexplained symptoms have occurred after other modern conflicts, the prevalence of GWI among Gulf War veterans has proven higher than those of prior conflicts.⁸

The Persian Gulf War Veterans Act of 1998 and the Veterans Programs Enhancement Act of 1998 mandated studies by the Institute of Medicine (IOM) on the biologic and chemical exposures that may have contributed to illness in the Kuwaiti theater of operations.⁹ However, elucidating the etiology and underlying pathophysiology of GWI has been a major research challenge. In the absence of objective diagnostic measures, an understanding of the fundamental pathophysiology, evidence-based treatments, a single case definition, and definitive guidelines for health care providers (HCPs) for the diagnosis and management of GWI has not been produced. As a result, veterans with GWI have struggled for nearly 3 decades to find a consistent diagnosis of and an effective treatment for their condition.

According to a report by the Government Accountability Office (GAO), the VA approved only 17% of claims for compensation for veterans with GWI from 2011 to 2015, about one-third the level of approval for all other claimed disabilities.¹⁰ Although the VA applied GAO recommendations to improve the compensation process, many veterans consider that their illness is treated as psychosomatic in clinical practice, despite emerging evidence of GWI-associated biomarkers.¹¹ Others think they have been forgotten due to their short 1-year period of service in the Gulf War.¹² To realign research, guidelines, clinical care, and the health care experience of veterans with GWI, focused QI within VHA is urgently needed.

Veterans of Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND) are experiencing similar CMI symptoms. A study of US Army Reserve OEF/OIF veterans found that > 60% met the CDC-10 case definition for GWI 1-year postdeployment.¹³ Thus, CMI is emerging as a serious health problem for post-9/11 veterans. The evidence of postdeployment CMI among veterans of recent conflicts underscores the need to increase efforts at a national level, beginning with the VHA. This report includes a summary of Gulf War veterans’ experiences at the Minneapolis VA Health Care System (MVAHCS) and a proposal for QI of MVAHCS processes focused on HCP education and clinical care.

Methods

To determine areas of GWI health care that needed QI at the MVAHCS, veterans with GWI were contacted for a telephone survey. These veterans had participated in the Gulf War Illness Inflammation Reduction Trial (ClinicalTrials.gov. Identifier: NCT02506192). Therefore, all met the Kansas case definition for GWI.⁴ The aim of the survey was to characterize veterans’ experiences seeking health care for chronic postdeployment symptoms.

Sixty Gulf War veterans were contacted by telephone and invited to participate in a 15-minute survey about their experience seeking diagnosis and treatment for GWI.

Verbal consent was requested, and 30 veterans agreed to participate in the survey.

MILWAUKEE – Individuals with chronic pain frequently have disrupted sleep and also may be at risk for opioid use disorder. However, even with advanced monitoring, it’s not clear how sleep modulates pain and opioid cravings.

Sleep has an impact on positive and negative affect, but new research shows that the link between sleep and mood states that may contribute to opioid use disorder is not straightforward. At the scientific meeting of the American Pain Society, Patrick Finan, PhD, of Johns Hopkins University, Baltimore, discussed how sleep and mood affect cravings for opioids among those in treatment for opioid use disorder (OUD).

Affective function, mesolimbic system function, and pain modulation are all adversely affected by poor sleep, said Dr. Finan, who told attendees that one key question he and his colleagues were seeking to answer was whether those with OUD and chronic pain had more disturbed sleep than those with OUD alone. Also, the researchers wanted to know whether the ups and downs of sleep on a day-to-day basis were reflected in pain scores among those with OUD, as would be predicted by prevailing models.

Finally, two “proximal indicators” of relapse risk, affect and heroin craving, might be affected by both sleep and pain, and Dr. Finan and collaborators sought to explore that association.

The work was part of a larger study looking at the natural history of OUD and OUD with comorbid chronic pain. To participate in this parent study, adults with OUD had to be seeking treatment or currently enrolled in methadone or buprenorphine maintenance treatment, and without current major depressive disorder. Also, patients could not have a history of significant mental illness, cognitive impairment, or a medical condition that would interfere with study participation. A total of 56 patients participated, and 20 of these individuals also had chronic pain.

Those with OUD and chronic pain qualified if they had pain (not related to opioid withdrawal) averaging above 3 on a 0-10 pain rating scale over the past week; additional criteria included pain for at least the past 3 months, with 10 or more days per month of pain.

Pain ratings were captured via a smartphone app that prompted participants to enter a pain rating at three random times during each day. Each evening, patients also completed a sleep diary giving information about bedtime, sleep onset latency, waking after sleep onset, and wake time for the preceding day.

A self-applied ambulatory electroencephalogram applied to the forehead was used for up to 7 consecutive nights to capture sleep continuity estimates; the device has been validated against polysomnography data in other work. Participants were given incentives to use the device, and this “yielded strong adherence,” with an average of 5 nights of use per participant, Dr. Finan said.

Patients were an average age of about 49 years, and were 75% male. African American participants made up just over half of the cohort, and 43% were white. Participants were roughly evenly divided in the type of maintenance therapy they were taking. Overall, 39% of participants had a positive urine toxicology screen.

For patients with chronic pain, 45% of all momentary pain reports had a pain score over zero, with a mean of 32 days of pain. Looking at the data another way, 58% of all patient-days had at least one momentary report of pain greater than zero, said Dr. Finan. On average, participants recorded a pain score of 2.27.

Brief Pain Inventory scores at baseline showed a mean severity of 5, and a pain interference score of 5.07.

Participants with OUD and chronic pain did not differ across any EEG-recorded sleep measures, compared with those with OUD alone. However, subjective reports of sleep were actually better overall for those with chronic pain than the objective EEG reports. The EEG recordings captured an average of 9.11 minutes more of waking after sleep onset (P less than .001). Also, total sleep time was 10.37 minutes shorter as recorded by the EEG than by self-report (P less than .001). Overall sleep efficiency was also worse by 5.96 minutes according to the EEG, compared with self-report (P less than .001).

“Sleep is objectively poor but subjectively ‘normal’ and variable in opioid use disorder patients,” Dr. Finan said. In aggregate, however, neither diary-based subjective nor EEG-based objective sleep measures differed between those with and without chronic pain in the research cohort. This phenomenon of sleep efficiency being self-reported as higher than objective measures capture sleep has also been seen in those newly abstinent from cocaine, Dr. Finan said, adding that it’s possible individuals with substance use disorder who are new to treatment simply feel better than they have in some time along many dimensions, with sleep being one such domain.

Pain on a given day didn’t predict poor sleep on that night, except that sleep onset took slightly longer (P = .01), said Dr. Finan. He noted that “there was no substantive effect on other sleep continuity parameters.”

Looking at how negative affect mediated craving for heroin, Dr. Finan and colleagues found that negative affect–related craving was significantly greater for those with chronic pain (P less than .001). Unlike findings in patients without OUD, having disrupted sleep continuity was more associated with increased daily negative affect, rather than decreased positive affect. And this increased negative affect was associated with heroin cravings, said Dr. Finan. “In the past few years, we’ve seen quite a few studies that have found some abnormalities in the reward system in patients with chronic pain.” Whether poor sleep is a mediator of these abnormalities deserves further study.

The study was supported by the National Institutes of Health. Dr. Finan reported no outside sources of funding.

PHILADELPHIA – Approaches to managing tics in patients with Tourette syndrome or chronic tic disorders “should be individualized, and the choice should be the result of a collaborative decision among patient, caregiver, and clinician, during which the benefits and harms of individual treatments as well as the presence of comorbid disorders are considered,” according to Tamara Pringsheim, MD, lead author of a practice guideline published May 6, 2019, by the American Academy of Neurology, and her collaborators.

The panel of nine physicians, two psychologists, and two patient representatives developed the recommendations based on a comprehensive systematic literature review. They concluded that treatments may decrease the frequency and severity of tics but rarely eliminate them.

The guideline was endorsed by the Child Neurology Society and the European Academy of Neurology and is the first such guideline for American neurologists, said Dr. Pringsheim of the University of Calgary (Alta.). Like recent Canadian and European guidelines, it strongly supports the Comprehensive Behavioral Intervention for Tics (CBIT) as a treatment option for tics.

After examining which medical, behavioral, and neurostimulation interventions, compared with placebo or other active interventions, improve tic severity and tic-related impairment in children and adults with Tourette syndrome or a chronic tic disorder, the guideline writers recommended that the evidence was strongest for CBIT as a first-line treatment, relative to other behavioral treatments and medications.

If symptoms affect a patient’s daily life, doctors should consider CBIT, said guideline author John Piacentini, PhD, of the University of California, Los Angeles, at the annual meeting of the American Academy of Neurology. “This treatment combines habit-reversal training, which teaches patients how to control their urges to tic, with other behavioral strategies to reduce stress and other factors that often make tics worse.”

Patients typically see results from CBIT in 8-12 weeks. More CBIT providers are needed, however, to make the treatment readily available to all patients, he said.

The guideline panel members said that there was moderate confidence in the evidence for reduced tic severity for the following therapeutic approaches, compared with placebo: haloperidol, risperidone, aripiprazole (children only), tiapride (children only), clonidine, onabotulinumtoxinA injections, ningdong granule (as formulated by Zhao), (children only), and ling granule (children only). There was low or very low confidence in the evidence for all other therapies for reducing tic severity.
 

Comorbid conditions

Many people with tic disorders have neurodevelopmental or psychiatric conditions such as ADHD, obsessive-compulsive disorder, and mood and anxiety disorders. The guideline recommends that people with tics be evaluated for these conditions.

Alpha2-adrenergic agonists may improve symptoms of tic disorders and ADHD, the authors said. There was moderate confidence in the evidence for reduced tic severity for people with a comorbid diagnosis of ADHD with clonidine plus methylphenidate (children only) and methylphenidate alone (children only), compared with placebo.

Adults with severe Tourette syndrome who are resistant to medical and behavioral therapy may benefit from deep brain stimulation (DBS), the guideline states. There was moderate confidence in the evidence for reduced tic severity for DBS of the globus pallidus, compared with sham DBS, as an option for adults with severe tics who have failed CBIT and drugs. These patients first must be screened by a mental health professional and continue to be monitored throughout DBS treatment.

Adults with Tourette syndrome who self-treat their tics with cannabis in states where cannabis is legal should see a doctor who can monitor the use of cannabis for efficacy and adverse effects, the guideline says.

Adverse effects of therapy

The panel also examined the risks of harm, including weight gain, elevated prolactin levels, sedation, drug-induced movement disorders, hypotension, bradycardia, and ECG changes with medical treatments, compared with placebo or other active interventions. In regard to weight gain, the panel concluded with moderate confidence that people with tics receiving risperidone or aripiprazole (children only) are probably more likely to gain weight than people receiving placebo. There was low confidence for associations between specific therapies and elevated prolactin levels.

Compared with people receiving placebo, there was moderate confidence that tiapride is probably associated with higher rates of physical tiredness and sleep disturbances (children only), that clonidine is probably associated with sedation, and that guanfacine is probably associated with drowsiness (children only). There was moderate evidence that pimozide is probably associated with extrapyramidal symptoms. There was low confidence that any specific treatment led to hypotension, bradycardia, or ECG changes.

Additional guideline specifics

The guideline’s practice recommendations include explaining the natural history of tic disorders to patients and caregivers and evaluating patients for functional impairment. Watchful waiting is an acceptable approach in people who do not experience functional impairment, and patients receiving medications for tics must have periodic reevaluations for the need for ongoing medical treatment. People with Tourette syndrome should be referred to resources for psychoeducation for teachers and peers, such as the Tourette Association of America.

Comorbid ADHD occurs in 30%-50% of patients with tics. If screening for ADHD is positive, the burden of ADHD symptoms should be assessed and those with functionally impairing ADHD should be treated for the disorder. Similarly, obsessive-compulsive behaviors occur in 10%-50% of those with Tourette syndrome. If an assessment finds comorbid obsessive-compulsive disorder, it should be treated.

Other psychiatric comorbidities with Tourette syndrome include anxiety disorders, oppositional defiant disorder, and mood disorders. When screening for these conditions, one must inquire about suicidal thoughts and suicide attempts and refer to appropriate resources if present, according to the guidelines.

Individuals with tics and comorbid ADHD should be advised that alpha2-adrenergic agonists may provide benefit for both conditions. Alpha2-adrenergic agonists should be prescribed for the treatment of tics when the benefits of treatment outweigh the risks and patients must be counseled regarding common side effects of alpha2-adrenergic agonists, including sedation. Heart rate and blood pressure must be monitored in patients with tics treated with alpha2-adrenergic agonists. If prescribing extended-release guanfacine, one must monitor the QTc interval in patients with a history of cardiac conditions, patients taking other QT-prolonging agents, or patients with a family history of long QT syndrome. If discontinuing alpha2-adrenergic agonists, they must gradually be tapered to avoid rebound hypertension.

If considering antipsychotic therapies, patients must be counseled on the relative risk for extrapyramidal, hormonal, and metabolic adverse effects to inform decision making on which antipsychotic should be prescribed. Before prescribing antipsychotics for tics, ECGs must be performed. The QTc interval must be measured before and after starting pimozide or ziprasidone, or if antipsychotics are coadministered with other drugs that can prolong the QT interval. The lowest effective dose should be prescribed to decrease the risk of adverse effects, and patients should be monitored for drug-induced movement disorders and for metabolic and hormonal adverse effects of antipsychotics. When attempting to discontinue antipsychotics for tics, the medications should be gradually tapered over weeks to months to avoid withdrawal dyskinesias.

If topiramate is prescribed, patients must be counseled regarding common adverse effects, including cognitive and language problems, somnolence, weight loss, and an increased risk of renal stones.

Some patients with Tourette syndrome use cannabis as a self-medication for tics and comorbidities. Because of the risks associated with cannabis use and widespread self-medication with cannabis for tics, where regional legislation and resources allow, physicians must offer to direct patients to appropriate medical supervision when cannabis is used as self-medication for tics. Appropriate medical supervision would entail education and monitoring for efficacy and adverse effects, according to the guidelines.

Where regional legislation allows, physicians prescribing cannabis-based medication must prescribe the lowest effective dose to decrease the risk of adverse effects. Physicians prescribing cannabis-based medication must inform patients that medication may impair driving ability. Physicians prescribing cannabis-based medication to patients with Tourette syndrome must periodically reevaluate the need for ongoing treatment.

A multidisciplinary evaluation is needed to establish when the benefits of treatment outweigh the risks for prescribing DBS for medication-resistant motor and phonic tics. The DSM-5 diagnosis of Tourette syndrome must be confirmed and exclude secondary and functional tic-like movements when considering DBS for medication-resistant tics. A mental health professional must screen patients preoperatively and follow patients postoperatively for psychiatric disorders that may impede the long-term success of the therapy. Physicians must confirm that multiple classes of medication (antipsychotics, dopamine depleters, alpha1 agonists) and behavioral therapy have been administered (or are contraindicated) before prescribing DBS for tics.

The practice guideline was developed with financial support from AAN. Dr. Pringsheim reported no disclosures. Dr. Piacentini reported receiving funding for travel and speaking from foundations and universities and has received royalties from publishers. In addition, he has performed behavior therapy for tics for approximately 50% of his clinical time and has received financial or material support from Pfizer, the National Institute of Mental Health, and foundations.

Like recent Canadian and European guidelines, it strongly supports the Comprehensive Behavioral Intervention for Tics (CBIT) as a treatment option for tics.

After examining which medical, behavioral, and neurostimulation interventions, compared with placebo or other active interventions, improve tic severity and tic-related impairment in children and adults with Tourette syndrome or a chronic tic disorder, the guideline writers recommended that the evidence was strongest for CBIT as a first-line treatment, relative to other behavioral treatments and medications.

If symptoms affect a patient’s daily life, doctors should consider CBIT, said guideline author John Piacentini, PhD, of the University of California, Los Angeles, at the annual meeting of the American Academy of Neurology. “This treatment combines habit-reversal training, which teaches patients how to control their urges to tic, with other behavioral strategies to reduce stress and other factors that often make tics worse.”

Patients typically see results from CBIT in 8-12 weeks. More CBIT providers are needed, however, to make the treatment readily available to all patients, he said.

The guideline panel members said that there was moderate confidence in the evidence for reduced tic severity for the following therapeutic approaches, compared with placebo: haloperidol, risperidone, aripiprazole (children only), tiapride (children only), clonidine, onabotulinumtoxinA injections, ningdong granule (as formulated by Zhao), (children only), and ling granule (children only). There was low or very low confidence in the evidence for all other therapies for reducing tic severity.
 

Comorbid conditions

Many people with tic disorders have neurodevelopmental or psychiatric conditions such as ADHD, obsessive-compulsive disorder, and mood and anxiety disorders. The guideline recommends that people with tics be evaluated for these conditions.

Alpha2-adrenergic agonists may improve symptoms of tic disorders and ADHD, the authors said. There was moderate confidence in the evidence for reduced tic severity for people with a comorbid diagnosis of ADHD with clonidine plus methylphenidate (children only) and methylphenidate alone (children only), compared with placebo.

Adults with severe Tourette syndrome who are resistant to medical and behavioral therapy may benefit from deep brain stimulation (DBS), the guideline states. There was moderate confidence in the evidence for reduced tic severity for DBS of the globus pallidus, compared with sham DBS, as an option for adults with severe tics who have failed CBIT and drugs. These patients first must be screened by a mental health professional and continue to be monitored throughout DBS treatment.

Adults with Tourette syndrome who self-treat their tics with cannabis in states where cannabis is legal should see a doctor who can monitor the use of cannabis for efficacy and adverse effects, the guideline says.

Adverse effects of therapy

The panel also examined the risks of harm, including weight gain, elevated prolactin levels, sedation, drug-induced movement disorders, hypotension, bradycardia, and ECG changes with medical treatments, compared with placebo or other active interventions. In regard to weight gain, the panel concluded with moderate confidence that people with tics receiving risperidone or aripiprazole (children only) are probably more likely to gain weight than people receiving placebo. There was low confidence for associations between specific therapies and elevated prolactin levels.

Compared with people receiving placebo, there was moderate confidence that tiapride is probably associated with higher rates of physical tiredness and sleep disturbances (children only), that clonidine is probably associated with sedation, and that guanfacine is probably associated with drowsiness (children only). There was moderate evidence that pimozide is probably associated with extrapyramidal symptoms. There was low confidence that any specific treatment led to hypotension, bradycardia, or ECG changes.

Additional guideline specifics

The guideline’s practice recommendations include explaining the natural history of tic disorders to patients and caregivers and evaluating patients for functional impairment. Watchful waiting is an acceptable approach in people who do not experience functional impairment, and patients receiving medications for tics must have periodic reevaluations for the need for ongoing medical treatment. People with Tourette syndrome should be referred to resources for psychoeducation for teachers and peers, such as the Tourette Association of America.

Comorbid ADHD occurs in 30%-50% of patients with tics. If screening for ADHD is positive, the burden of ADHD symptoms should be assessed and those with functionally impairing ADHD should be treated for the disorder. Similarly, obsessive-compulsive behaviors occur in 10%-50% of those with Tourette syndrome. If an assessment finds comorbid obsessive-compulsive disorder, it should be treated.

Other psychiatric comorbidities with Tourette syndrome include anxiety disorders, oppositional defiant disorder, and mood disorders. When screening for these conditions, one must inquire about suicidal thoughts and suicide attempts and refer to appropriate resources if present, according to the guidelines.

Individuals with tics and comorbid ADHD should be advised that alpha2-adrenergic agonists may provide benefit for both conditions. Alpha2-adrenergic agonists should be prescribed for the treatment of tics when the benefits of treatment outweigh the risks and patients must be counseled regarding common side effects of alpha2-adrenergic agonists, including sedation. Heart rate and blood pressure must be monitored in patients with tics treated with alpha2-adrenergic agonists. If prescribing extended-release guanfacine, one must monitor the QTc interval in patients with a history of cardiac conditions, patients taking other QT-prolonging agents, or patients with a family history of long QT syndrome. If discontinuing alpha2-adrenergic agonists, they must gradually be tapered to avoid rebound hypertension.

If considering antipsychotic therapies, patients must be counseled on the relative risk for extrapyramidal, hormonal, and metabolic adverse effects to inform decision making on which antipsychotic should be prescribed. Before prescribing antipsychotics for tics, ECGs must be performed. The QTc interval must be measured before and after starting pimozide or ziprasidone, or if antipsychotics are coadministered with other drugs that can prolong the QT interval. The lowest effective dose should be prescribed to decrease the risk of adverse effects, and patients should be monitored for drug-induced movement disorders and for metabolic and hormonal adverse effects of antipsychotics. When attempting to discontinue antipsychotics for tics, the medications should be gradually tapered over weeks to months to avoid withdrawal dyskinesias.

If topiramate is prescribed, patients must be counseled regarding common adverse effects, including cognitive and language problems, somnolence, weight loss, and an increased risk of renal stones.

Some patients with Tourette syndrome use cannabis as a self-medication for tics and comorbidities. Because of the risks associated with cannabis use and widespread self-medication with cannabis for tics, where regional legislation and resources allow, physicians must offer to direct patients to appropriate medical supervision when cannabis is used as self-medication for tics. Appropriate medical supervision would entail education and monitoring for efficacy and adverse effects, according to the guidelines.

Where regional legislation allows, physicians prescribing cannabis-based medication must prescribe the lowest effective dose to decrease the risk of adverse effects. Physicians prescribing cannabis-based medication must inform patients that medication may impair driving ability. Physicians prescribing cannabis-based medication to patients with Tourette syndrome must periodically reevaluate the need for ongoing treatment.

A multidisciplinary evaluation is needed to establish when the benefits of treatment outweigh the risks for prescribing DBS for medication-resistant motor and phonic tics. The DSM-5 diagnosis of Tourette syndrome must be confirmed and exclude secondary and functional tic-like movements when considering DBS for medication-resistant tics. A mental health professional must screen patients preoperatively and follow patients postoperatively for psychiatric disorders that may impede the long-term success of the therapy. Physicians must confirm that multiple classes of medication (antipsychotics, dopamine depleters, alpha1 agonists) and behavioral therapy have been administered (or are contraindicated) before prescribing DBS for tics.

The practice guideline was developed with financial support from AAN. Dr. Pringsheim reported no disclosures. Dr. Piacentini reported receiving funding for travel and speaking from foundations and universities and has received royalties from publishers. In addition, he has performed behavior therapy for tics for approximately 50% of his clinical time and has received financial or material support from Pfizer, the National Institute of Mental Health, and foundations.

A single oral dose of aspirin did not improve the sensitivity of the fecal immunochemical test to identify advanced colorectal neoplasms in a randomized trial of 2,134 adults.

The study was inspired by an observational study in which the sensitivity of the fecal immunochemical test (FIT) was enhanced in adults taking aspirin for cardiovascular disease prevention.

It was surmised that “aspirin predisposes to subclinical bleeding and, hence, increased detection of advanced adenomas by FIT. This suggests that administration of aspirin prior to fecal sampling might be a practical intervention to increase FIT sensitivity,” wrote Hermann Brenner, MD, of the German Cancer Research Center, Heidelberg, and colleagues.

In a study published in JAMA, the researchers analyzed 2,134 adults aged 40-80 years who were scheduled for colonoscopy. The study participants, who had no recent use of aspirin or other drugs with antithrombotic effects, were randomized to a 300-mg aspirin tablet or a placebo tablet 2 days before stool samples were obtained. The average age of the participants was 60 years, and 78% of the colonoscopies were for primary screening.

Overall, 224 of the study participants had advanced neoplasms, including 216 individuals with advanced adenoma and 8 with colorectal cancer.

Sensitivity was not significantly different between the aspirin and placebo groups at either of two predefined cutoffs of 10.2-mcg Hb/g stool (40.2% and 30.4%, respectively) and 17-mcg Hb/g stool (28.6% and 22.5%, respectively).

Two serious adverse events occurred in the aspirin group but were not considered related to aspirin. No serious adverse events were reported in the placebo group.

Although the results do not support the findings from previous observational studies, they suggest the need for more research of the potential impact of aspirin on FIT sensitivity, the researchers said.

“This trial was designed to detect a 24% absolute increase in sensitivity and was not adequately powered to detect small differences that may nevertheless be clinically meaningful given the low morbidity observed, the low cost of a single dose of aspirin, and the ease of implementation of this intervention across health systems,” they explained.

Additional limitations of the study included lack of adjustment for multiple testing in secondary analyses, inability to analyze subtypes of advanced neoplasms, and the inclusion of only one round of screening. FIT programs usually include multiple rounds, the researchers said. Therefore, “potential effects on detection of advanced neoplasms and reduction of CRC incidence and mortality in the long run are yet to be determined.”

PHILADELPHIA – Applying a criterion of three lesions with central vein signs distinguishes between multiple sclerosis and its mimics with high specificity and moderate sensitivity, according to research presented at the annual meeting of the American Academy of Neurology. Using this criterion in clinical practice is feasible, the researchers added.

Several years ago, researchers proposed the central vein sign as a specific and sensitive imaging biomarker for distinguishing between multiple sclerosis (MS) and its imaging mimics. Recent studies have proposed criteria for this distinction that are based on the proportion of lesions with the central vein sign. Criteria that are based on the absolute numbers of lesions with the central vein sign, however, may be more applicable in clinical practice, said Tim Sinnecker, MD, research associate at the University of Basel (Switzerland).


Dr. Sinnecker and colleagues conducted a multicenter study to evaluate the sensitivity and specificity of criteria that are based on the absolute numbers of lesions with the central vein sign (CVS) in distinguishing MS from non-MS conditions on clinical 3T brain MRI. They analyzed 606 participants with clinically isolated syndrome (CIS; n = 117), relapsing remitting MS (RRMS; n = 236, of whom 108 had a disease duration shorter than 5 years), aquaporin 4 antibody–positive neuromyelitis optica spectrum disorder (n = 32), systemic lupus erythematosus (n = 25), migraine (n = 29), cluster headache (n = 5), diabetes mellitus (n = 20), or other types of small-vessel disease (n = 142). Raters blinded to clinical data and lesion distribution determined the occurrence of CVS on 3T T2*-weighted or susceptibility-weighted imaging. The researchers assessed the sensitivity and specificity of different CVS lesion criteria that were defined according to the absolute numbers of lesions with CVS.


In total, Dr. Sinnecker and colleagues analyzed 4,447 lesions. The “two-CVS-lesions criterion” (two or more lesions with CVS) had a sensitivity and specificity of 76.2% and 79.3%, respectively, in distinguishing between RRMS/CIS and non-MS. The “three-CVS-lesions criterion” (three or more lesions with CVS) had a sensitivity and specificity of 61.9% and 89.0%, respectively. The observed sensitivity and specificity values were consistent across all disease subgroups examined in the study, including CIS and early RRMS. These results indicate that positive criteria based on CVS could be used to support the diagnosis of MS, Dr. Sinnecker said.

Dr. Sinnecker reported receiving personal compensation for consulting, serving on a scientific advisory board, speaking, or other activities with Actelion.

PHILADELPHIA – Applying a criterion of three lesions with central vein signs distinguishes between multiple sclerosis and its mimics with high specificity and moderate sensitivity, according to research presented at the annual meeting of the American Academy of Neurology. Using this criterion in clinical practice is feasible, the researchers added.

Several years ago, researchers proposed the central vein sign as a specific and sensitive imaging biomarker for distinguishing between multiple sclerosis (MS) and its imaging mimics. Recent studies have proposed criteria for this distinction that are based on the proportion of lesions with the central vein sign. Criteria that are based on the absolute numbers of lesions with the central vein sign, however, may be more applicable in clinical practice, said Tim Sinnecker, MD, research associate at the University of Basel (Switzerland).


Dr. Sinnecker and colleagues conducted a multicenter study to evaluate the sensitivity and specificity of criteria that are based on the absolute numbers of lesions with the central vein sign (CVS) in distinguishing MS from non-MS conditions on clinical 3T brain MRI. They analyzed 606 participants with clinically isolated syndrome (CIS; n = 117), relapsing remitting MS (RRMS; n = 236, of whom 108 had a disease duration shorter than 5 years), aquaporin 4 antibody–positive neuromyelitis optica spectrum disorder (n = 32), systemic lupus erythematosus (n = 25), migraine (n = 29), cluster headache (n = 5), diabetes mellitus (n = 20), or other types of small-vessel disease (n = 142). Raters blinded to clinical data and lesion distribution determined the occurrence of CVS on 3T T2*-weighted or susceptibility-weighted imaging. The researchers assessed the sensitivity and specificity of different CVS lesion criteria that were defined according to the absolute numbers of lesions with CVS.


In total, Dr. Sinnecker and colleagues analyzed 4,447 lesions. The “two-CVS-lesions criterion” (two or more lesions with CVS) had a sensitivity and specificity of 76.2% and 79.3%, respectively, in distinguishing between RRMS/CIS and non-MS. The “three-CVS-lesions criterion” (three or more lesions with CVS) had a sensitivity and specificity of 61.9% and 89.0%, respectively. The observed sensitivity and specificity values were consistent across all disease subgroups examined in the study, including CIS and early RRMS. These results indicate that positive criteria based on CVS could be used to support the diagnosis of MS, Dr. Sinnecker said.

It might be the ultimate medical innovation – an artificial heart – and generations of physicians have pursued it, a story told in “Ticker: The Quest to Create an Artificial Heart.”

Author Mimi Swartz feared this history was being forgotten. “The larger-than-life personalities – Dr. Michael DeBakey and Dr. Denton Cooley – were such dominant figures for more than 50 years; I couldn’t stand for that history to be lost,” she said. “Also, so many innovations happened in Houston, including the implantation of the first artificial heart and the development of the Left Ventricular Assist Device – I couldn’t stand for that information to be lost too.”

Writing this book taught her a lot about innovation in medicine, the trade-offs involved in medical progress, even who benefits most.

“One of the most important things to think about is how many of these high-tech devices we need, and who will get them – who will be able to afford them,” she said.

“Medical innovation over the last 50 years is a global, billion dollar business, fraught with pitfalls: legal, governmental, ethical, financial, and, finally, personal,” Ms. Swartz said. “A great invention that could save millions of lives can end up on the junk heap because a hedge fund lost interest, while another great invention moves forward, but was stolen from the lab of another researcher. The persistence required to bring a medical device to market is daunting. One inventor told me, ‘If I’d known what was going to happen, I never would have even started.’ ”

PHILADELPHIA – Laquinimod appears not to improve motor function or clinical outcomes in patients with Huntington’s disease, according to a study presented at the annual meeting of the American Academy of Neurology. However, the drug reduced brain volume loss in the caudate and other regions.

Laquinimod is an investigational immunomodulatory drug that prevents inflammation and neurodegeneration in the CNS. The treatment was studied as a therapy for multiple sclerosis (MS), but development for this indication has been stopped. Researchers have observed that laquinimod modulates inflammatory pathways that are involved in Huntington’s disease pathology.

Ralf Reilmann, MD, PhD, founder of the George Huntington Institute and chair of the Huntington unit at the University of Münster (Germany), and colleagues conducted the phase 2 LEGATO-HD study at 48 sites in 10 countries to examine the efficacy and safety of laquinimod in patients with early Huntington’s disease. Participants were randomized in double-blind fashion to daily placebo or 0.5-mg, 1.0-mg, or 1.5-mg doses of laquinimod for 52 weeks. After the initiation of this trial, studies of the drug in MS indicated that the 1.5-mg dose was associated with cardiovascular risks, and Dr. Reilmann and his colleagues discontinued the 1.5-mg arm of their trial as a precaution.

The primary endpoint of LEGATO-HD was the change from baseline in the Unified Huntington’s Disease Rating Scale (UHDRS)–Total Motor Score (TMS). The secondary endpoint was the percent change in caudate volume at week 52 for the 1.0-mg dose group, compared with controls. The investigators also examined exploratory endpoints such as changes in MRI volume measures and Quantitative Motor, Clinician Interview-Based Impression of Change plus caregiver input, UHDRS–Total Functional Capacity and UHDRS–Functional Assessment scores. Adverse event reporting and clinical and laboratory examinations constituted the safety measures.

Dr. Reilmann and colleagues found no difference between the treated patients and controls in UHDRS-TMS. However, they did observe less caudate volume loss in the laquinimod group, compared with controls. All MRI exploratory measures also favored laquinimod. The researchers found no treatment effects of laquinimod in rater-dependent clinical outcome measures. Laquinimod was well tolerated, and the study yielded no new safety findings.

Dr. Reilmann has received research support from Teva, which supported the LEGATO-HD trial and in 2018 sold development and commercial rights for laquinimod to Active Biotech. He has received research support from a variety of other pharmaceutical companies and organizations, including the CHDI Foundation and the European Huntington Disease Network.
