Joint Hypermobility, Autonomic Dysfunction, Gastrointestinal Dysfunction and Autoimmune markers (JAG-A): Clinical Associations and Response to Intravenous Immunoglobulin Therapy.

INTRODUCTION: We examined autoimmunity markers (AIM) and autonomic dysfunction in patients with chronic neurogastroenterological symptoms and their relationship to joint hypermobility/hypermobility spectrum disorder (JH/HSD). METHODS: AIM positivity was defined as a diagnosis of known autoimmune/autoinflammatory disorder (AIDX) with at least one positive seromarker of autoimmunity or at least two positive seromarkers by themselves. Three cohorts were studied: (a) Retrospective (n = 300); (b) Prospective validation cohort (n =133); and (c) Treatment cohort (n=40), administered open-label intravenous immunoglobulin (IVIG). RESULTS: AIM positivity was found in 40% and 29% of the retrospective and prospective cohorts, the majority of whom (71% and 69%, respectively) had AIDX. Significantly more patients with AIM had elevations of C-reactive protein (31% versus 15%, p<0.001) along with an increased proportion of cardiovascular autonomic dysfunction (48% versus 29%; p<.001), small fiber neuropathy (20% versus 9%; p=.002).8) and HLADQ8 positivity (24% versus 13%, p=.01). JH/HSD patients were more likely to have AIM (43% versus 15%, p=.001) along with more severe autonomic and gastrointestinal symptom scores. IVIG treatment was associated with robust improvement in pain, gastrointestinal and autonomic symptoms but adverse events were experienced by 62% patients. CONCLUSIONS: Autoimmune markers and autonomic dysfunction are common in patients with unexplained gastrointestinal symptoms, especially in those with JH/HSD. Many patients seem to respond to IVIG treatment but this needs to be confirmed by controlled trials. These results highlight the need for vigilance for autoimmune and autonomic factors and JH/HSD in patients with neurogastroenterological disorders. Clinicaltrials.gov, NCT04859829.

Homocysteine modifies the association of coronary stenosis and HIV infection in an inner city African American population.

BACKGROUND AND AIMS: People with HIV (PWH) whose disease is controlled on anti-retroviral regimens remain at an increased risk for coronary artery disease (CAD). Traditional cardiovascular risk factors do not fully explain the residual risk in PWH suggesting contributions from nontraditional factors. Homocysteine (Hcy) may be one of these as prior work in adults without HIV demonstrate that Hcy may impair endothelial function by decreasing the availability of nitric oxide, promoting the development of atherosclerosis. In addition, plasma Hcy levels are higher in PWH than in individuals living without HIV. The aim of this study was to investigate whether Hcy levels influence the association between HIV and coronary stenosis in an inner city African American population. METHODS: African Americans from the Heart Study in Baltimore, with and without HIV, recruited from inner-city Baltimore between June 2004 and February 2015, were included in this analysis. Participants underwent coronary CT angiography to evaluate the presence of coronary stenosis, defined as luminal stenosis >10%. Hcy was measured from stored serum samples. RESULTS: In this analysis, the median [IQR] age of the 664 participants was 56 [50-66] years; 68.1% were living with HIV and 43.1% were women. Elevated Hcy (>15 µmol/L) was more prevalent in those with coronary stenosis (23.3%, 95% CI: 18.4%-28.2%) than in those without coronary stenosis (13.1%, 95% CI: 9.7%-16.5%) (p = 0.0007), and HIV was associated with coronary stenosis in those participants with an elevated Hcy (Prevalence Ratio: 1.94, 95% CI: 1.04-3.64, p = 0.0038) and not in those with a Hcy ≤15 µmol/L (Prevalence Ratio: 1.02, 95% CI: 0.83-1.25, p = 0.87). CONCLUSIONS: Our data suggest an association between elevated Hcy levels (>15 µmol/L) and the prevalence of coronary stenosis in PWH from this inner city African American population.

Elevated homocysteine levels may moderate and mediate the association between HIV and cognitive impairment among middle-aged and older adults in an underserved population in Baltimore, Maryland.

Background: In the antiretroviral therapy (ART) era, HIV-associated neurocognitive disorders (HAND) remain a considerable challenge for people with HIV, yet not all such disorders can be attributed to HIV alone. This study aimed to: (1) identify factors influencing neurocognitive impairment (NCI) utilizing the NIH Toolbox Cognition Battery (NIHTB-CB) as per the revised research criteria for HAND; (2) ascertain the moderating role of high homocysteine levels in the association between NCI and HIV; and (3) assess the mediating effect of elevated homocysteine levels on this association.Methods: We analyzed data from 788 adults (≥45 years) participating in a study on HIV-related comorbidities in underserved Baltimore communities, using NIHTB-CB to gauge neurocognitive performance. Special attention was given to results from the Dimensional Change Card Sort (DCCS) test within the executive function domain during causal mediation analysis.Results: Overall, HIV was not associated with NCI presence. However, HIV was associated with NCI among individuals with homocysteine >14 µmol/L. Furthermore, HIV was both directly and indirectly associated with NCI in DCCS test scores. Notably, the mediating role of elevated homocysteine in DCCS scores was only observable among individuals who had never used cocaine or had used it for ≤ 10 years, suggesting that extended cocaine use may have a substantial influence on cognitive performance.Conclusions: The findings from this study suggest elevated homocysteine levels may moderate and mediate the association between HIV and neurocognitive impairment.

Cocaine Use May Moderate the Associations of HIV and Female Sex with Neurocognitive Impairment in a Predominantly African American Population Disproportionately Impacted by HIV and Substance Use.

HIV-associated neurocognitive disorders (HAND) remain a major challenge for people with HIV in the antiretroviral therapy era. Cocaine use may trigger/exacerbate HAND among African American (AA) adults, especially women. Between 2018 and 2019, 922 adults, predominantly AAs, with/without HIV and with/without cocaine use in Baltimore, Maryland, were enrolled in a study investigating the association of HIV and cocaine use with neurocognitive impairment (NCI). Neurocognitive performance was assessed with the NIH Toolbox Cognition Battery (NIHTB-CB). NCI was considered to be present if the fully adjusted standard score for at least two cognitive domains was 1.0 standard deviation below the mean. Although the overall analysis showed HIV and female sex were associated with NCI, the associations were dependent on cocaine use. Neither HIV [adj prevalence ratio (PR): 1.12, confidence interval (95% CI): 0.77-1.64] nor female sex (adj PR: 1.07, 95% CI: 0.71-1.61) was associated with NCI among cocaine nonusers, while both HIV (adj PR: 1.39, 95% CI: 1.06-1.81) and female sex (adj PR: 1.53, 95% CI: 1.18-1.98) were associated with NCI in cocaine users. HIV was associated with two NIHTB-CB measures overall. In addition, HIV was associated with a lower dimensional change card sort score (an executive function measure) in cocaine users and not in nonusers. Cognitive performance was poorer in female than in male cocaine users. The adverse effect of HIV on cognitive performance predominantly affected cocaine users. However, cocaine use may moderate the impact of HIV and female sex on cognitive performance, highlighting the importance of reducing cocaine use in NCI prevention among the AA population.

High-risk Coronary Plaque Regression in Cash-based Contingency Management Intervention Among Cocaine Users With HIV-associated Subclinical Coronary Atherosclerosis.

BACKGROUND: Cocaine use exacerbates human immunodeficiency virus (HIV)-associated subclinical coronary atherosclerosis. We investigated whether cocaine abstinence or reduced use achieved with contingency management (CM) intervention would retard high-risk coronary plaque progression among cocaine users with HIV and subclinical coronary atherosclerosis. METHODS: Between March 2014 and August 2017, 76 cocaine users with HIV and coronary plaques were enrolled in a study designed to decrease cocaine use and determine whether doing so impacted progression of subclinical coronary atherosclerosis as measured by coronary artery computed tomography examinations. Of the 76, 7 did not complete the study, resulting in 69 participants. A 12-month cash-based CM intervention was implemented to promote cocaine abstinence or reduced cocaine use. Generalized estimating equation approach was used to perform longitudinal data analyses. FINDINGS: During the 12-month CM, all 69 participants reduced cocaine use, and of these, 25 (36%; 95% confidence interval, 25%-49%) achieved cocaine abstinence. After adjusting for potential confounding factors, generalized estimating equation analyses showed that (1) endothelin-1 (ET-1) levels, a proinflammatory biomarker for endothelial dysfunction, at the 6-month and 12-month visits were significantly lower compared with baseline ET-1 ( P = 0.001 and P < 0.001, respectively), and (2) low-attenuation noncalcified coronary plaque volume, a predictor for myocardial infarction, at 12-month visit was significantly lower compared with baseline low-attenuation noncalcified coronary plaque volume ( P < 0.05). CONCLUSIONS: The findings of this study have not only demonstrated that CM is effective in achieving a sustained reduction in cocaine use, but also provided compelling evidence that reduction in cocaine use leads to quantifiable cardiovascular health benefits, including concurrent decrease in high-risk plaque burden and ET-1, among cocaine users with HIV-associated coronary atherosclerosis.

Diet-Related and Gut-Derived Metabolites and Health Outcomes: A Scoping Review.

We conducted a scoping review to map available evidence about the health impact of gut microbiota-derived metabolites. We searched PubMed and Embase for studies that assessed the health impact of ten metabolites on any health condition: deoxycholate or deoxycholic acid (DCA), lithocholate or lithocholic acid (LCA), glycolithocholate or glycolithocholic acid, glycodeoxycholate or glycodeoxycholic acid, tryptamine, putrescine, d-alanine, urolithins, N-acetylmannosamine, and phenylacetylglutamine. We identified 352 eligible studies with 168,072 participants. Most (326, 92.6%) were case-control studies, followed by cohort studies (14, 4.0%), clinical trials (8, 2.3%), and cross-sectional studies (6, 1.7%). Most studies assessed the following associations: DCA on hepatobiliary disorders (64 studies, 7976 participants), colorectal cancer (19 studies, 7461 participants), and other digestive disorders (27 studies, 2463 participants); LCA on hepatobiliary disorders (34 studies, 4297 participants), colorectal cancers (14 studies, 4955 participants), and other digestive disorders (26 studies, 2117 participants); putrescine on colorectal cancers (16 studies, 94,399 participants) and cancers excluding colorectal and hepatobiliary cancers (42 studies, 4250 participants). There is a need to conduct more prospective studies, including clinical trials. Moreover, we identified metabolites and conditions for which systemic reviews are warranted to characterize the direction and magnitude of metabolite-disease associations.

Should Physicians Disclose Their Own Health Challenges? Perspectives of Patients With Chronic Pain.

This study explores how patients with chronic pain view the impact of physician self-disclosure on the patient-physician relationship. We conducted mixed-methods analyses of a cross-sectional survey eliciting experiences and attitudes regarding physician self-disclosure among 934 adults with self-reported chronic pain. Patients with chronic pain commonly recalled experiences of physician self-disclosure, most often "small talk" or physicians' disclosure of their own chronic pain. Patients generally rated these experiences to be beneficial. Patients frequently said they would benefit from seeing a physician who has had chronic pain, or that they would want their physician to self-disclose their own chronic pain. Those who had never experienced self-disclosure were more likely to want their physician to self-disclose their own chronic pain. Nonetheless, patients held varying perspectives toward the advantages and disadvantages of physician self-disclosure, believing that self-disclosure could either positively or negatively impact the patient-physician relationship and care and communication.

Pancreatic Pain-Knowledge Gaps and Research Opportunities in Children and Adults: Summary of a National Institute of Diabetes and Digestive and Kidney Diseases Workshop.

ABSTRACT: A workshop was sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases to focus on research gaps and opportunities in pancreatic pain. The event was held on July 21, 2021, and structured into 4 sessions: (1) pathophysiology; (2) biomarkers, mediators, and pharmacology of pain; (3) pain assessment; and (4) pain treatment challenges and opportunities. The current state of knowledge was reviewed; many knowledge gaps and research needs were identified that require further investigation. Common themes included the need to better understand the underlying mechanisms of pain in pancreatic diseases, the relationship of visceral neural pathways and central pain centers, the role of behavioral factors and disorders on the perception of pain, and differences in pain perception and processes in children when compared with adults. In addition, the role of genetic risk factors for pain and the mechanisms and role of placebos in pain treatment were discussed. Methods of pain assessment including quantitative sensory testing were examined, as well as the process of central sensitization of pain. Finally, newer approaches to pain management including cognitive behavioral therapy, nerve stimulation, experimental (nonopioid) drugs, and cannabinoid compounds were covered.

Inflammation and Risk of Depression in HIV: Prospective Findings From the Multicenter AIDS Cohort Study.

Studies suggest that inflammation might be involved in the pathogenesis of depression. Individuals with human immunodeficiency virus (HIV) have a higher risk of depression and elevated inflammatory profiles. Despite this, research on the link between inflammation and depression among this high-risk population is limited. We examined a sample of men who have sex with men from the Multicenter AIDS Cohort Study in prospective analyses of the association between inflammation and clinically relevant depression symptoms, defined as scores >20 on Center for Epidemiological Studies Depression Scale. We included 1,727 participants who contributed 9,287 person-visits from 1984 to 2010 (8,218 with HIV (HIV+) and 1,069 without (HIV-)). Exploratory factor analysis (EFA) was used to characterize underlying inflammatory processes from 19 immune markers. Logistic regression with generalized estimating equations was used to evaluate associations between inflammatory processes and depressive symptoms stratified by HIV serostatus. Three EFA-identified inflammatory processes (EIPs) were identified. EIP-1 scores-described by soluble tumor necrosis factor receptor 2 (sTNF-R2), soluble interleukin-2 receptor α (sIL-2Rα), sCD27, B-cell activating factor, interferon γ-induced protein 10 (IP-10), soluble interleukin-6 receptor (sIL-6R), sCD14, and sGP130-were significantly associated with 9% higher odds of depressive symptoms in HIV+ participants (odds ratio = 1.09; 95% confidence interval: 1.03, 1.16) and 33% higher odds in HIV- participants (odds ratio = 1.33; 95% confidence interval: 1.09, 1.61). Findings suggest that immune activation might be involved in depression risk among both HIV+ and HIV- men who have sex with men.

Engagement in treatment for depression among people who inject drugs in Baltimore, Maryland.

INTRODUCTION: Mental health care may mitigate negative consequences related to substance use and bolster engagement in care for drug dependence. Despite the increased risk of depression among people who inject drugs (PWID), the longitudinal relationship of depression symptoms with depression and drug treatment utilization in this population remains uncharacterized. METHODS: Data on depressive symptoms and depression treatment from current and former PWID in the ALIVE (AIDS Linked to the IntraVenous Experience) community-based cohort who had ≥3 study visits from July 2005 to June 2016 were included. We used logistic regression analysis with generalized estimating equations to examine factors associated with depression treatment in the 12 months following reported major depressive symptoms (CES-D ≥ 23) in the absence of treatment. We further examined the association between depression, depression treatment, and subsequent engagement in drug treatment among those with active substance use or alcohol dependence. RESULTS: Of the 1544 participants, 34% were female, the median age was 51 years, and 91% were African-American. PWID reported major depressive symptoms at 22% of study visits. In adjusted analysis, acute emergency care, suicidal ideation, and recent alcohol or drug treatment were positively associated with initiating depression treatment. Depression was positively associated with subsequent treatment for substance dependence among those actively using (aOR = 1.30, 95% CI: 1.10-1.53). CONCLUSIONS: PWID experience a high burden of depressive symptoms with significant unmet need of treatment for depression. Our findings suggest that mental health providers should bolster connections to chronic disease and alcohol and drug treatment providers.

Optimal metrics for identifying long term patterns of depression in older HIV-infected and HIV-uninfected men who have sex with men.

OBJECTIVES: Center of Epidemiologic Studies-Depression Scale (CES-D) provides a snapshot of symptom severity at a single point in time. However, the best way of using CES-D to classify long-term depression is unclear. METHOD: To identify long-term depression among HIV-infected and HIV-uninfected 50+ year-old men who have sex with men (MSM) with at least 5 years of follow-up, we compared sensitivities and specificities of CES-D-based metrics (baseline CES-D; four consecutive CES-Ds; group-based trajectory models) thresholded at 16 and 20 to a clinician's evaluation of depression phenotype based on all available data including CES-D history, depression treatment history, drug use history, HIV disease factors, and demographic characteristics. RESULTS: A positive depressive phenotype prevalence was common among HIV-infected (prevalence = 33.1%) and HIV-uninfected MSM (prevalence = 23.2%). Compared to the depressive phenotype, trajectory models of CES-D≥20 provided highest specificities among HIV-infected (specificity = 99.9%, 95% Confidence Interval [CI]:99.4%-100.0%) and HIV-uninfected MSM (specificity = 99.0%, 95% CI:97.4%-99.7%). Highest sensitivities resulted from classifying baseline CES-D ≥ 16 among HIV-infected MSM (sensitivity = 75.0%, 95% CI:67.3%-81.7%) and four consecutive CES-Ds ≥ 16 among HIV-uninfected MSM (sensitivity = 81.0%, 95% CI:73.7%-87.0%). CONCLUSION: Choice of method should vary, depending on importance of false positive or negative rate for long-term depression in HIV-infected and HIV-uninfected MSM.

Clinical solutions to chronic pain and the opiate epidemic.

The current opiate epidemic has caused tens of thousands of deaths annually and hundreds of billions in economic losses. From 1979 to 2015, accidental opiate-related deaths increased by 4250%. Despite its magnitude, the driving forces remain poorly understood. A narrow understanding by physicians, administrators and policy makers has resulted in a clinical approach to chronic pain treatment misguided by expediency, shortsighted cost reduction, pharmaceutical profit, and patient satisfaction. Until the broken elements are well understood, effective policy solutions will remain elusive. In this review, we describe the first comprehensive timeline of significant contributing factors between 1979 and the present. To address the complexity of treating patients with chronic pain and its contribution to opiate overuse, we outline an alternative clinical and health systems approach to chronic pain therapy. Addressing the underlying drivers will require empowering physicians to use clinical judgment over guidelines and algorithms to provide holistic, high-quality healthcare to individual victims of the opiate epidemic.

Cocaine use may induce telomere shortening in individuals with HIV infection.

BACKGROUND: Although cocaine use may induce/accelerate HIV-associated comorbidities in HIV-infected individuals on antiretroviral therapy (ART), and that HIV itself may accelerate aging, the issue of whether cocaine use plays a role in HIV-associated aging in HIV-infected cocaine users has not been reported. The goals of this study were (1) to explore factor(s) associated with peripheral blood leukocyte telomere length, a marker of cellular replicative history, and telomere shortening in HIV-infected individuals, and (2) to assess whether cocaine use plays a role in accelerating telomere shortening in cocaine users with HIV infection. METHODS: Between June 2010 and December 2016, 147 HIV-infected participants in Baltimore, Maryland, were enrolled in a cross-sectional study investigating factor(s) associated with telomere length. Of these 147, 93 participated in a follow-up study to examine factor(s) associated with telomere shortening. Robust regression model was used to analyze cross-sectional data and the generalized estimating equation approach was used to analyze follow-up data. RESULTS: Cross-sectional analyses demonstrated that (1) both daily alcohol consumption and use of non-nucleoside reverse transcriptase inhibitors (NNRTIs) were independently associated with telomere length, and cocaine use modified the associations of daily alcohol use and NNRTI use with telomere length. Longitudinal analyses suggested that both daily alcohol consumption and duration of NNRTI use were independently associated with telomere shortening, and (2) cocaine use induced/accelerated telomere shortening in HIV-infected individuals. CONCLUSIONS: Our findings suggest that cocaine use may promote premature aging in HIV-infected individuals who are on ART. Our results emphasize the importance of cocaine abstinence/reduced use, which may retard HIV-associated premature aging.

2017 HIV Medicine Association of Infectious Diseases Society of America Clinical Practice Guideline for the Management of Chronic Pain in Patients Living With Human Immunodeficiency Virus.

Pain has always been an important part of human immunodeficiency virus (HIV) disease and its experience for patients. In this guideline, we review the types of chronic pain commonly seen among persons living with HIV (PLWH) and review the limited evidence base for treatment of chronic noncancer pain in this population. We also review the management of chronic pain in special populations of PLWH, including persons with substance use and mental health disorders. Finally, a general review of possible pharmacokinetic interactions is included to assist the HIV clinician in the treatment of chronic pain in this population.It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. The Infectious Diseases Society of American considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.

Cocaine use may modify HIV/ART-associated myocardial steatosis and hepatic steatosis.

BACKGROUND: It has been recognized that myocardial and hepatic steatosis may be more prevalent in HIV-infected individuals on antiretroviral therapy (ART); however, factors associated with these conditions have not been thoroughly investigated. The goals of this study were (1) to identify the risk factors for myocardial and hepatic steatosis in HIV-infected African Americans (AAs) and explore whether ART use is independently associated with myocardial and hepatic steatosis, and (2) to examine whether and how cocaine use influences any associations of ART use with myocardial and hepatic steatosis. METHODS: Between June 2010 and December 2013, 220 HIV-infected AAs in Baltimore, Maryland, were enrolled in a study investigating HIV/ART-associated myocardial and hepatic damage. Proton magnetic resonance spectroscopy was performed to quantify myocardial and hepatic triglyceride contents. Sociodemographic, medical and laboratory data were also obtained. Robust regression model was employed to perform primary statistical analysis. RESULTS: Robust regression analyses showed that (1) duration of protease inhibitor (PI) use was independently associated with myocardial and hepatic triglyceride contents, (2) duration of PI use was independently associated with myocardial triglyceride in cocaine users (p=0.025), but not in cocaine never-users (p=0.84), and (3) duration of PI use was independently associated with hepatic triglyceride in cocaine users, but not in cocaine never-users (p=0.52). CONCLUSIONS: Cocaine use may trigger/exacerbate the toxicity of PI in ART-associated myocardial and hepatic steatosis, suggesting that cocaine abstinence/reduced use may retard these ART-associated comorbidities. Clinical trials should be conducted to examine whether reduced cocaine use improves HIV/AIDS-associated myocardial and hepatic steatosis.

Association of long-term patterns of depressive symptoms and attention/executive function among older men with and without human immunodeficiency virus.

Older HIV-infected men are at higher risk for both depression and cognitive impairments, compared to HIV-uninfected men. We evaluated the association between longitudinal patterns of depressive symptoms and attention/executive function in HIV-infected and HIV-uninfected men aged 50+ years to understand whether HIV infection influenced the long-term effect of depression on attention/executive function. Responses to the Center for Epidemiologic Studies-Depression scale and attention/executive function tests (Trail Making Test Part B and Symbol Digit Modalities Test) were collected semiannually from May 1986 to April 2015 in 1611 men. Group-based trajectory models, stratified by HIV status, were used to identify latent patterns of depressive symptoms and attention/executive function across 12 years of follow-up. We identified three depression patterns for HIV-infected and HIV-uninfected men (rare/never 50.0 vs. 60.6%, periodically depressed 29.6 vs. 24.5%, chronic high 20.5 vs.15.0%, respectively) and three patterns of attention/executive function for HIV-infected and HIV-uninfected men (worst-performing 47.4 vs. 45.1%; average 41.9 vs. 47.0%; best-performing 10.7 vs. 8.0%, respectively). Multivariable logistic regression models were used to assess associations between depression patterns and worst-performing attention/executive function. Among HIV-uninfected men, those in the periodically depressed and chronic high depressed groups had higher odds of membership in the worst-performing attention/executive function group (adjusted odds ratio [AOR] = 1.45, 95% CI 1.04, 2.03; AOR = 2.25, 95% CI 1.49, 3.39, respectively). Among HIV-infected men, patterns of depression symptoms were not associated with patterns of attention/executive function. Results suggest that HIV-uninfected, but not HIV-infected, men with chronic high depression are more likely to experience a long-term pattern of attention/executive dysfunction.

Neuropsychiatric Effects of HIV Antiviral Medications.

The development of antiretroviral therapy (ART) has dramatically increased the lifespan of HIV patients but treatment is complicated by numerous adverse effects and toxicities. ART complications include neuropsychiatric, metabolic, gastrointestinal, cardiac, and numerous other toxicities, and clinicians often have to choose one toxicity over another to offer the best medication regimen for a patient. Some antiviral drugs cause significant neuropsychiatric complications, including depression, cognitive impairment, and sleep disturbance. Even in careful studies, it may be difficult to determine which effects are related to the virus, the immune system, or the treatment. Of the six currently marketed classes of antiviral drugs, the nucleoside reverse transcriptase inhibitors and the non-nucleoside reverse transcriptase inhibitors have been most commonly associated with neuropsychiatric complications. Within these classes, certain drugs are more likely to cause difficulty than others. We review the contention regarding the central nervous system (CNS) complications of efavirenz, as well as debate about the role of CNS penetration in drug effectiveness and toxicity. A thorough working knowledge of the neuropsychiatric consequences of ART allows clinicians to tailor treatment more successfully to individual patients as well as to identify ART more quickly as the source of a problem or symptom.
