Background. Obesity and lipohypertrophy are common in treated human immunodeficiency virus (HIV) infection and contribute to morbidity and mortality among HIV-infected adults on antiretroviral ...therapy (ART). Methods. We present a consensus opinion on the diagnosis, clinical consequences, and treatment of excess adiposity in adults with treated HIV infection. Results. Obesity and lipohypertrophy commonly occur among HIV-infected adults on ART and may have overlapping pathophysiologies and/or synergistic metabolic consequences. Traditional, HIV-specific, and ART-specific risk factors all contribute. The metabolic and inflammatory consequences of excess adiposity are critical drivers of non-AIDS events in this population. Although promising treatment strategies exist, further research is needed to better understand the pathophysiology and optimal treatment of obesity and lipohypertrophy in the modern ART era. Conclusions. Both generalized obesity and lipohypertrophy are prevalent among HIV-infected persons on ART. Aggressive diagnosis and management are key to the prevention and treatment of end-organ disease in this population and critical to the present and future health of HIV-infected persons.
Background. Low 25-hydroxyvitamin D (25(OH)D) has been associated with inflammation, human immunodeficiency virus (HIV) disease progression, and death. We aimed to identify the prognostic value of ...25(OH) D for AIDS, non-AIDS-defining events and death, and its association with immunological/inflammatory markers. Methods. Prospective 1-1 case-control study nested within the EuroSIDA cohort. Matched cases and controls for AIDS (n = 50 matched pairs), non-AIDS-defining (n = 63) events and death (n = 41), with plasma samples during follow-up were selected. Conditional logistic regression models investigated associations between 25(OH)D levels and annual 25(OH)D change and the probability of events. Mixed models investigated relationships between 25(OH) D levels and immunological/inflammatory markers. Results. In sum, 250 patients were included. Median time between first and last sample and last sample and event was 44.6(interquartile range IQR: 22.7-72.3) and 3.1(IQR: 1.4-6.4) months. Odds of death decreased by 46.0%(95% confidence interval CI, 2.0-70.0, P= .04) for a 2-fold increase in latest 25(OH) D level. There was no association between 25(OH) D and the occurrence of AIDS or non-AIDS-defining events (P >.05). In patients with current 25(OH) D < 10 ng/mL, hsIL-6 concentration increased by 4.7%(95% CI, .2,9.4, P =.04) annually after adjustment for immunological/inflammatory markers, and no change in hsCRP rate was observed (P =.76). Conclusions. Low Vitamin D predicts short term mortality in HIV-positive persons. Effectiveness of vitamin D supplementation on inflammation and patient outcomes should be investigated.
