RESUMEN
BACKGROUND: Depression has been reported in 8-45% of patients with posttreatment Lyme symptoms (PTLS), but little is known about suicidal ideation in these patients. METHOD: Depression and suicidal ideation were assessed using the Beck Depression Inventory (BDI-II). Scores from the PTLS group (n = 81) were compared to those from 2 other groups: HIV+ patients being treated for fatigue (n = 70), and a nonpatient comparison group (NPCG; n = 44). ANOVA and t-tests were used to compare groups; logistic regression was used to identify the strongest correlates of suicidal ideation. RESULTS: Mean BDI-II scores fell in the mildly depressed range for PTLS and HIV+ patients, with both groups having higher depression scores than the NPCG. Suicidal ideation was reported by 19.8% of the PTLS patients and 27.1% of the HIV+ patients, a nonsignificant difference. Among those with mild or no depression, suicidal ideation was uncommon (6.5% PTLS and 11.9% HIV+). Among the patients with moderate-to-severe depression, suicidal ideation was more common (63.2% of 19 PTLS and 50% of 28 HIV+); among these, 2 with PTLS and 1 with HIV+ expressed suicidal intent. Further, 4.5% (n = 2) of the NPCG had suicidal ideation, each had scores in the moderate-to-severe depression range. Higher scores on the cognitive symptoms subscale of the BDI-II predicted greater likelihood of suicidal ideation across patient groups. CONCLUSION: As expected, suicidal ideation is increased among patients who are depressed. The fact that 1 in 5 patients with PTLS reported suicidal ideation highlights the importance of screening for depression and suicidality to optimize patient care.

BACKGROUND: Depression and fatigue are common in chronic hepatitis C (CHC). OBJECTIVE: We report clinical predictors of these conditions in patients seen in a university clinic. METHODS: A total of 167 CHC patients completed the Patient Health Questionnaire-9 (PHQ-9) and Fatigue Severity Scale (FSS). Major depressive disorder (MDD) suggested by PHQ-9 was confirmed by clinical interview. FSS scores ≥41 were considered clinically significant fatigue. Logistic and multiple regression models were employed for analysis. RESULTS: Thirty-three percent of patients had MDD and 52% had clinically significant fatigue. Sixty-one percent were HIV-infected, among whom both MDD and clinically significant fatigue were significantly less prevalent (OR = 0.47 and 0.46, respectively). MDD was least common in patients without a history of IV drug use (OR = 0.28), and highest in methadone users (OR = 3.57). Compared with methadone users, patients with no history of IV drug use and former IV drug users had less severe fatigue (coefficients = -31.0, -34.0, respectively). Lack of a history of hepatitis treatment was also associated with less severe fatigue (coefficient= -7.6). CONCLUSION: Our study confirms high prevalence of fatigue and depression in CHC. HIV-positivity was associated with lower rates of MDD and clinically significant fatigue, arguably due to support systems for people living with HIV. Higher rates of depression in methadone users might be due to intrinsically higher rates of psychopathology in this group. Being on hepatitis treatment was associated with higher rates of fatigue, probably due to the adverse effects of interferon. Our findings emphasize the importance of routine screening and evaluation of depression and fatigue in CHC populations.

BACKGROUND: Dihydroepiandrosterone (DHEA) has been investigated for its potential role in improving cognition in a number of patient populations. Treatment options are limited for HIV-associated neurocognitive disorders. OBJECTIVE: The authors tested the effect of DHEA administration on the cognitive functioning of HIV-positive subjects with non-major depression. METHOD: The neuropsychological testing data for 60 HIV-positive patients enrolled in a clinical trial for non-major depression were analyzed to determine if DHEA-treated patients demonstrated improved cognitive functioning versus placebo. RESULTS: At baseline, 80% of the sample met criteria for asymptomatic cognitive impairment. No benefit in cognitive performance was found on 16 of 17 neuropsychological measures evaluated. One measure showed a modest benefit for placebo-treated patients over DHEA. CONCLUSION: DHEA treatment was not associated with improved cognitive performance in HIV-positive patients with non-major depression.

Objective: To identify occupational risk factors for ALS using well-characterized participants with ALS (P-ALS), sibling controls (S-controls), and matched population controls (P-controls) within the National ALS Registry. We also compared oxidative stress (OS) biomarkers between groups. Methods: P-ALS were recruited over 4 years. Demographic, socioeconomic, and medical data were ascertained from medical records and structured interviews. P-ALS were followed prospectively for 2 years or until death, whichever came sooner. S-controls and age-, sex-, race/ethnicity-, and residential location-matched P-controls were recruited over 3 years. Occupational exposure to lead and agricultural chemicals (ACs) were assigned by an occupational hygienist, blinded to case status. OS biomarkers in urine were measured. Results: P-ALS (mean age 62.8 years; 63% males) resided across the United States. Demographic and socioeconomic variables did not differ among P-ALS, S-controls, and P-controls. P-ALS were more likely to report occupations with exposure to lead (adjusted OR (aOR)=2.3, 95% CI 1.1, 4.6) and ACs (aOR = 2.4, 95% CI 1.2, 4.6) compared to pooled controls. Among those with occupations with exposure to both lead and ACs, aOR was 7.2 (95% CI 2.0, 26.1). Urinary 8-oxo-dG was significantly elevated among P-ALS (11.07 ± 5.42 ng/mL) compared to S-controls, P-controls, or pooled controls (pooled 7.43 ± 5.42 ng/mL; p < 0.0001) but was not associated with occupational exposure to either lead or ACs. Conclusions: Findings reveal increased risk of ALS diagnosis among those with occupational exposure to lead and ACs and increased OS biomarkers among cases compared to controls. OS may be an important pathogenic mechanism in ALS.

OBJECTIVE: To evaluate the efficacy and safety of armodafinil in the treatment of fatigue in HIV+ patients, and to assess its effect on depressive symptoms and behavior once fatigue remitted. METHOD: HIV+ patients with clinically significant fatigue were treated in a placebo-controlled randomized double-blind trial for 4 weeks. Armodafinil responders and placebo non-responders or relapsers were treated openly for a total of 16 weeks with armodafinil. The primary outcome measure for fatigue and depression was the Clinical Global Impressions-Improvement Scale, supplemented by the Fatigue Severity Scale, the Hamilton Depression Rating Scale, and the Beck Depression Inventory. Safety was assessed with assays of CD4 cell count and HIV RNA viral load and the SAFTEE side effects rating scale. Maximum trial dose of armodafinil was 250 mg/d. RESULTS: Seventy patients were enrolled. Attrition was 9%. In intention-to-treat analyses, fatigue response rate to armodafinil was 75% and to placebo, 26%. Armodafinil did not reduce depressive symptoms in the absence of improved energy, but of those patients with an Axis I depressive disorder at study entry whose energy improved, 82% experienced improved mood as well. Markers of immunologic suppression did not change during treatment. At 6 months, those still taking armodafinil had more energy and fewer depressive symptoms than those who were no longer taking it. CONCLUSIONS: As we found in our RCT of modafinil, armodafinil appears effective and well tolerated in treating fatigue in HIV+ patients. Side effects were minimal and most patients reported substantially improved energy and mood.

BACKGROUND: Despite improved health and during a strong job market (pre-COVID-19), a substantial proportion of HIV+ adults remained unemployed. This study sought to provide time-limited counseling to promote employment goals. OBJECTIVE: To determine whether behavioral activation (BA) or supportive counseling (SC), would be more effective in promoting vocational goals (full or part-time, paid or volunteer). METHODS: The study included two groups: those with clinically significant fatigue, who were first treated with armodafinil. Once their fatigue diminished, they were enrolled in the counseling program. Those without fatigue were enrolled directly. Both BA and SC interventions were manualized, consisting of eight individual sessions plus a follow-up. RESULTS: 116 participants entered counseling, including 87 assigned to BA and 29 to SC. Of these, 79 completed counseling or found a job by session eight. By follow-up, 51%of BA versus 41%of SC participants had found jobs, a non-significant difference either clinically or statistically. CONCLUSIONS: Multiple issues contributed to difficulty in employment, including gaps in resumes, loss of contact with former colleagues, and uncertainty about career direction. Ongoing barriers included substance use, housing instability, ambivalence about forfeiting government benefits, as well as inadequately treated depression. Success in employment for about half of participants is, in this context, a reasonable outcome.

Our objective was to determine the prevalence and predictors of cognitive impairment in ALS, measure differences in survival among impaired and unimpaired patients, and assess changes in neuropsychological test performance over time. Fifty patients were enrolled in a prospective cohort study of neuropsychological performance. ANOVA and chi(2) tests assessed differences in clinical characteristics and neuropsychologic test results; general estimating equations assessed change in test performance; multiple regression determined which variables contributed to cognitive status; and Cox models compared survival. Thirty-six patients were categorized as cognitively normal, and 14 were impaired. Impaired patients were older at testing (p = 0.024), but no more likely to have bulbar signs. Predicators of impairment were symptom duration (p < 0.001), motor function (p < 0.001), and rate of ALS progression (p < 0.001). The Benton recognition (p < 0.001), Boston naming (p = 0.001), Wisconsin Card Sort (p = 0.001) and word generation (p = 0.001) tests contributed most strongly to cognitive status. Survival was worse in impaired patients (p = 0.027). Over time, only animal word generation declined (p = 0.016). In conclusion, 28% percent of patients were cognitively impaired. Older age and more severe ALS were associated with impairment. The strongest neuropsychological predictors of cognitive status were measures of executive, episodic memory and language function. Cognitively impaired patients had shorter survival time.

Our objective was to assess the impact of personal, situational and patient characteristics on mood, and changes over time, among ALS caregivers. Seventy-one patient-caregiver pairs were interviewed once and 51 (72%) monthly until endpoints of death or tracheostomy for long-term mechanical ventilation (LTMV). Depressive symptoms and DSM-IV disorders, coping strategies, caregiver burden, satisfaction with care-giving, and patient disease severity were assessed. At baseline, 13% of caregivers had major depression, and 10% had minor depression. Rates declined at last visit before death or LTMV (median interval three months), as did depressive symptoms. Correlates of caregiver depression included reliance on avoidance, perceived burden, fatigue, and feeling that the patient was critical and unappreciative. Half of the 14 caregivers of patients who planned LTMV were depressed at baseline, declining to 8% at endpoint, versus 16% (9/57) among caregivers of patients who died, declining non-significantly to 11%. While few personal or situational factors were correlated with caregiver distress, patients' plans and degree of supportiveness influenced caregiver mood. Verbal comments of caregivers clarified the distinction between sadness and psychiatric depression. The high baseline rate of depression among caregivers of patients who planned tracheostomy decreased as caregivers instituted major changes in patient care or personal counseling.

OBJECTIVES: To determine whether new-onset clinical depression emerges over time, and whether positive and negative mood levels change among patients with terminal cancer. METHODS: In this two-site study, 58 cancer patients seen at least twice were interviewed monthly until death or study termination. Major measures included the Patient Health Questionnaire-9, Holland System of Beliefs Inventory, and Positive and Negative Affect Schedule. RESULTS: At study entry, 7% of patients had major depressive disorder; another 9% had depressive symptoms but no Axis I diagnosis. Twenty-two percent were taking antidepressants. During visits ranging from 2 to 21 per patient, 76% of patients never had a depression diagnosis, 3% were always depressed, and 14% became depressed for the first time, almost exclusively at their final visit before death. Scores on positive mood were equivalent to or higher than scores on negative mood and did not change over time. Cancer site, hospice, spiritual beliefs, income, and caregiver mood were unrelated to depression. Spiritual beliefs were, however, associated with positive mood, hope, and better quality of life. CONCLUSIONS: In this exploratory study, terminally ill patients approaching death experienced positive as well as negative mood although a significant minority met criteria for major depression at the last visit before death. The findings suggest that major depression is not an inevitable part of the dying process in patients with terminal cancer. Further, the appropriateness of classifying sadness, loss of interest and thoughts that one would be better off dead in the last days of life as psychopathology should be reconsidered.

OBJECTIVES: To evaluate the efficacy of modafinil combined with cognitive behavioral therapy (CBT) for treatment of methamphetamine (MA) dependence among HIV+ gay men. METHODS: In a single blind trial, modafinil was administered for 12 weeks, followed by a 4-week placebo phase. CBT was conducted for 18 sessions over the 16-week study. Primary outcome measures were self-reported use of days per week plus urine toxicology assays. Additional measures included the Beck Depression Inventory, Cravings Scale, and O/C Crystal Use Scale. Response was defined as > 50% decline in days used per week. Thirteen patients were enrolled over an 18-month period. RESULTS: Ten patients (77%) completed the trial, although two discontinued modafinil due to side effects. Six of the ten study completers reduced their MA use by > 50%. CONCLUSIONS: These preliminary results suggest good retention using combined medication and psychotherapy, and support further examination of modafinil and CBT in double-blind placebo controlled trials.

BACKGROUND: Employment rates for people with HIV/AIDS are low, compared to the general population. One widespread barrier is fatigue, accompanied by daytime sleepiness and a lack of stamina. Previous pharmacological studies have demonstrated improvement of fatigue-related symptoms without affecting work-related goal attainmentOBJECTIVE:In this pilot study, we sought to determine whether a pharmacologic-behavioral two-phase combined approach could facilitate returning to work. METHODS: HIV+ participants with fatigue were treated with armodafinil. If energy improved, 8 sessions of biweekly manualized Behavioral Activation (BA) counseling were added to medication maintenance. Outcome was assessed on a 3-point scale along with clinician and self-ratings. RESULTS: Of the 46 participants enrolled in BA, 15 (33%) did not complete all 8 sessions: 6 got jobs so they no longer needed counseling; 4 did not like BA, and 5 dropped out for reasons such as moving away or substance use relapse. Of the 46, 29 (63%) attained their vocational goal and showed significant changes on self-report scales. CONCLUSIONS: Our integrated treatment including armodafinil plus BA counseling significantly increased the success of achieving work-related goals. The two-phase medication plus counseling program was well-tolerated by participants and the manualized BA counseling was readily applied by counselors without advanced mental health training, making the method potentially feasible in community settings.

Since the earliest days of the AIDS epidemic, clinicians have been concerned about the prevalence of depression among their patients. Epidemiologists, psychiatrists, psychologists, sociologists, and a broad array of other specialists have studied this topic, trying to determine the prevalence of depressive disorders and depressive symptoms as well as antecedents, correlates, and consequences. This review addresses the methodologic difficulties in determining depression prevalence, major findings regarding rates of disorder and correlates among different segments of the HIV community, effects of depression on HIV illness progression, psychopharmacologic and psychotherapeutic treatment findings, and behavioral effects of depression, such as its impact on medication adherence, employment, and risk behavior. Finally, the article summarizes international studies of depression prevalence in developing countries and the challenges regarding cross-national diagnostic definitions and measures.

INTRODUCTION: Our goal was to assess the long-term impact of AIDS activism of ACT UP/New York on the current adjustment of those who were members during its peak years (1987-1992), including assessment of trauma sequelae as well as posttraumatic growth. METHODS: A 90-minute semistructured interview and 6 validated self-report scales were administered. We relied on purposive and snowball sampling to recruit potential participants. Areas covered include demographics, ACT UP participation, and psychiatric problems. Self-report scales provided approximate diagnoses of PTSD and depression, as well as coping, optimism, and related concepts. RESULTS: Participants included 102 men (40% HIV-positive) and 23 women. Seventeen percent reported current symptoms suggesting PTSD, slightly above the range in general population studies. Symptoms consistent with depression were reported by 8% overall, with higher rates for HIV+ men. Enhanced sense of self, belief in change, and empowerment were reported by 93% of respondents, independent of concurrent PTSD or depression. CONCLUSIONS: Twenty-eight years later, ACT UP study participants recall their activist days during the AIDS epidemic as the peak experience of their lives. While some continue to have symptoms of stress and depression, most found that their activism has enriched their subsequent lives.
RESUMEN
Amyotrophic lateral sclerosis (ALS) is a devastating terminal neurodegenerative disease with a highly predictable clinical course such that palliative care should begin at or soon after diagnosis. The outcome is certain in most cases. The only medication approved for treatment in the United States, riluzole, extends life by about 2 months. Virtually all skeletal muscles eventually are affected. Multiple problems require a multidisciplinary approach including aggressive symptomatic management, rehabilitation to maintain motor function, nutritional and respiratory support, augmentative communication devices, and psychological support for both patients and families because family members so often play a central role in management and care. Social, bioethical, and financial issues as well as advance directives should be addressed long before enteral feeding or assistive ventilatory support might be considered. Goals of care should be assessed on an ongoing basis. Presenting the unusual case of a patient with ALS who is also a prominent neurologist specializing in ALS, we enumerate issues in management and palliative care applicable to ALS but also to other fatal, progressive neurologic diseases such as Huntington's chorea and late-stage Parkinson disease.

RESUMEN
Dehydroepiandrosterone (DHEA) is commonly used by HIV-infected men, but its endocrine effects in this population are not well defined. We conducted an 8-week randomized, placebo-controlled trial to determine the effects of escalating doses (100-400 mg/d) of DHEA on the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes, and on a number of metabolic parameters in 69 HIV-positive men (31 in DHEA-treated group, 38 in placebo group). High-dose (250 microg) corticotropin and luteinizing hormone-releasing hormone stimulation tests were carried out in all subjects. Fifty-four subjects (26 in the DHEA-treated group and 28 in the placebo group) also underwent optional corticotropin-releasing hormone test, and 67 subjects (31 in DHEA-treated group and 36 in placebo group) underwent optional low-dose (1 microg) corticotropin stimulation test. All tests were performed at baseline and at the end of week 8. Repeated-measures analysis of variance was used to analyze the data. We observed significant increases in circulating levels of DHEA, DHEA-sulfate, free testosterone, dihydrotestosterone, androstenedione, and estrone, and a decline in the serum concentration of sex hormone-binding globulin in the DHEA-treated group but not in the placebo group (P < .001). There were no differences between the groups in other endocrine or metabolic parameters or in the results of the stimulation tests. In conclusion, oral DHEA therapy in HIV-positive men significantly increases circulating levels of DHEA and DHEA-sulfate, free testosterone, dihydrotestosterone, androstenedione, and estrone and suppresses circulating concentration of sex hormone-binding globulin. Long-term studies are needed to assess the clinical significance of these hormonal changes in subjects with HIV infection receiving oral DHEA therapy.

OBJECTIVE: To evaluate relationships among cognitive, behavioral, and psychiatric/psychosocial measures assessed in a multicenter cohort of patients with amyotrophic lateral sclerosis (ALS). METHODS: Recently diagnosed patients with definite or probable ALS diagnosis were administered 7 standardized psychiatric/psychosocial measures, including the Patient Health Questionnaire for diagnosis of depression and elicitation of wish to die. The Cognitive Behavioral Screen was used to classify both cognitive and behavioral impairment (emotional-interpersonal function). An ALS version of the Frontal Behavioral Inventory and Mini-Mental State Examination were also administered. RESULTS: Of 247 patients included, 79 patients (32%) had neither cognitive nor behavioral impairment, 100 (40%) had cognitive impairment, 23 (9%) had behavioral impairment, and 45 (18%) had comorbid cognitive and behavioral decline. Cognitive impairment, when present, was in the mild range for 90% and severe for 10%. Thirty-one patients (12%) had a major or minor depressive disorder (DSM-IV criteria). Cognitive impairment was unrelated to all psychiatric/psychosocial measures. In contrast, patients with behavioral impairment reported more depressive symptoms, greater hopelessness, negative mood, and more negative feedback from spouse or caregiver. A wish to die was unrelated to either cognitive or behavioral impairment. CONCLUSIONS: While we found no association between cognitive impairment and depression or any measure of distress, behavioral impairment was strongly associated with depressive symptoms and diagnoses although seldom addressed by clinicians. Thoughts about ending life were unrelated to either cognitive or behavioral changes, a finding useful to consider in the context of policy debate about physician-assisted death.

RATIONALE: No studies to date have directly compared the tolerability and efficacy of smoked marijuana and oral dronabinol in HIV(+) marijuana smokers. OBJECTIVES: The aim of this study was to compare dronabinol (0, 10, 20, 30 mg p.o.) and marijuana [0.0, 1.8, 2.8, 3.9% Delta(9)-tetrahydrocannabinol (THC)] in two samples of HIV(+) marijuana smokers: those with (n=15) and those without (n=15) a clinically significant loss of muscle mass (<90% body cell mass/height), which is one component of AIDS wasting. METHODS: Mood, physical symptoms, self-selected food intake, cardiovascular data, and cognitive task performance were measured before and repeatedly after dronabinol and marijuana administration in eight 7-h sessions. Marijuana and dronabinol were administered in randomized order using a within-subject, staggered, double-dummy design. RESULTS: As compared to placebo, (1) marijuana (1.8, 2.8, 3.9% THC) and the lower dronabinol doses (10, 20 mg) were well tolerated (e.g., few physical symptoms, significant increases in ratings of "good drug effect") in both groups of participants; the highest dose of dronabinol (30 mg) was poorly tolerated in a subset of participants; (2) marijuana and dronabinol significantly increased caloric intake in the low bioelectrical impedance analysis (BIA) group but not in the normal BIA group; and (3) drug effects on cognitive performance were minor. CONCLUSIONS: These data suggest that for experienced marijuana smokers with clinically significant muscle mass loss, both dronabinol (at acute doses at least four to eight times the current recommendation) and marijuana produce substantial and comparable increases in food intake without producing adverse effects.

With the advent of potent combination antiretroviral therapy (ART), there has been a reduction in the incidence of wasting. However, few studies have investigated specific body composition changes associated with these treatments. This study aimed to investigate longitudinally the association of increasingly potent ART with changes in body cell mass and wasting utilizing bioelectric impedance analysis (BIA). In this longitudinal cohort study, 159 HIV-positive men were assessed semiannually from 1995 to 1997 for body composition utilizing BIA, CD4 lymphocyte count, HIV viral load, medical and depressive symptoms. Wasting was defined as body cell mass/height below the 90th percentile based on HIV positive norms. ART potency at each visit was scored utilizing published clinical guidelines, ranging from 1 (0-1 antiretrovirals) to 5 (3 or more antiretrovirals including a potent protease inhibitor). Viral resistance testing was not used. The mixed-effects model and the generalized estimating equations approaches were used to determine longitudinal correlates of body cell mass and of wasting, respectively. Over the 2 years of follow-up, potent combination ART use increased from 6% to 79%. Concurrently, a significant increase in mean body cell mass and a reduction in prevalence of wasting were seen, while total body weight, fat mass, and total body water did not change. Increasingly potent ART was associated with significant increases in body cell mass and reduction in wasting. Other significant correlates of increased body cell mass included higher CD4 count and decreased severity of HIV-related symptoms, fatigue and depression. The current study found that higher potency ART taken for relatively short term (2 years) was associated with an increase in body cell mass and a reduction in wasting and that these changes were associated with both medical (CD4, HIV symptoms) and behavioral (fatigue, depression) improvements. One caveat is this study did not distinguish among types of potent ART regimens. Given only some antiretrovirals appear linked to many body composition changes, regardless of their effect on viral load, it may be the type of regimen used that accounted for the relationship seen between viral load and body composition changes.
