PurposeWe determined the prevalence of risk factors for the development of acute respiratory distress syndrome (ARDS), outcomes of critical illness, and the impact of highly active antiretroviral therapy in HIV-1-infected patients. We hypothesized that in an urban county hospital, HIV-1-infected patients with ARDS would have a higher mortality than their HIV-1-uninfected counterparts.Materials And MethodsSubjects were enrolled between 2006 and 2012. Baseline patient demographics, comorbidities, illness severity, causes of ARDS, and clinical outcomes were obtained. The primary end point was hospital mortality.ResultsA total of 178 subjects with ARDS were enrolled in the study; 40 (22%) were infected with HIV-1. The median CD4 count was 75 (15.3-198.3), and 25% were on highly active antiretroviral therapy. HIV-1-infected subjects were significantly younger (44 vs 52 years; P < .01) and had higher rates of asthma, chronic obstructive pulmonary disease, pneumonia, history of hospital-acquired infections, and prior sepsis. HIV-1-infected subjects had greater illness severity by Acute Physiology and Chronic Health Evaluation II scores (29 [24-31] vs 24 [22-25]; P < .01). Hospital mortality was not higher among HIV-1-infected subjects compared with HIV-1-uninfected subjects (50.0% vs 38.4%; P = .19).ConclusionsIn patients with ARDS, HIV-1 infection was associated with greater illness severity but was not associated with higher mortality in ARDS. Future studies need to be done to evaluate the factors that contribute to high morbidity and mortality in medically vulnerable populations who develop ARDS.Copyright © 2014 Elsevier Inc.
