This study was conducted to investigate the prevalence of clinical fatigue reported by gay/bisexual men at all HIV illness stages, and whether fatigue, while associated with depression, independently contributes to limitations in physical function and disability. HIV- men, HIV+ men with CD4 counts >500, HIV+ men with CD4 counts 200 to 500, and men with AIDS were compared on prevalence of clinical fatigue, as defined by a standardized instrument. Among HIV+ men, the relationships among fatigue, depressed mood, major depressive disorder, HIV illness markers (including CD4 count and HIV RNA viral load), physical limitations, and disability were assessed at baseline and after 1 year. The prevalence of clinical fatigue in men with CD4 counts 500. However, fatigue was not directly correlated with CD4 count or HIV RNA. Fatigue was a chronic symptom that was associated with depressed mood, major depressive disorder, physical limitations, and disability. After 1 year, an increase in depressive symptoms predicted a small amount of variance in fatigue; however, depressive symptoms were not associated with physical limitations or disability after controlling for fatigue. Fatigue is a chronic symptom that is more prevalent in advanced HIV illness, and which, although associated with depression, does not seem to be merely a symptom of depression. Because fatigue contributes independently to physical limitations and disability, it should be assessed and treated.

Persistent cognitive, medical and psychiatric complaints have been extensively described after recovery from acute SARS-CoV-2 infection. To describe neuropsychological, medical, psychiatric, and functional correlates of cognitive complaints experienced after recovery from acute COVID-19 infection. Sixty participants underwent neuropsychological, psychiatric, medical, functional, and quality-of-life assessments 6–8 months after acute COVID-19. Those seeking care for cognitive complaints in a post-COVID-19 clinical program for post-acute symptoms of COVID-19 (clinical group, N = 32) were compared with those recruited from the community who were not seeking care (nonclinical, N = 28). A subset of participants underwent serological testing for proinflammatory cytokines C-reactive protein, interleukin-6, and tumor necrosis factor-α to explore correlations with neuropsychological, psychiatric, and medical variables. For the entire sample, 16 (27%) had extremely low test scores (less than second percentile on at least 1 neuropsychological test). The clinical group with cognitive complaints scored lower than age-adjusted population norms in tests of attention, processing speed, memory, and executive function and scored significantly more in the extremely low range than the nonclinical group (38% vs. 14%, P < 0.04). The clinical group also reported higher levels of depression, anxiety, fatigue, posttraumatic stress disorder, and functional difficulties and lower quality of life. In logistic regression analysis, scoring in the extremely low range was predicted by acute COVID-19 symptoms, current depression score, number of medical comorbidities, and subjective cognitive complaints in the areas of memory, language, and executive functions. Interleukin-6 correlated with acute COVID symptoms, number of medical comorbidities, fatigue, and inversely with measures of executive function. C-reactive protein correlated with current COVID symptoms and depression score but inversely with quality of life. Results suggest the existence of extremely low neuropsychological test performance experienced by some individuals months after acute COVID-19 infection, affecting multiple neurocognitive domains. This extremely low neuropsychological test performance is associated with worse acute COVID-19 symptoms, depression, medical comorbidities, functional complaints, and subjective cognitive complaints. Exploratory correlations with proinflammatory cytokines support further research into inflammatory mechanisms and viable treatments.
