Dyspnea and Pulmonary Function Among Participants in the Multicenter AIDS Cohort Study Using Protease Inhibitors: A Cross-Sectional Study.

People living with HIV (PLWH) have a higher prevalence of respiratory symptoms than people without human immunodeficiency virus (HIV). Antiretroviral therapy has been associated with worsened airflow limitation. This cross-sectional study assessed respiratory health impairment among PLWH and its association with protease inhibitor use using data from Multicenter AIDS Cohort Study visits between April 1, 2017 and March 31, 2018.

Brief Report: HIV Is Associated With Impaired Pulmonary Diffusing Capacity Independent of Emphysema.

Background: HIV is associated with accelerated decline in lung function and increased risk for chronic obstructive pulmonary disease (COPD). Recently, there has been growing attention toward the impairment in the diffusing capacity of the lungs for carbon monoxide (DLCO), a marker of pulmonary gas exchange, observed among persons living with HIV. Although increased emphysema can contribute to the DLCO impairment observed, other factors may drive this association.

Association of Lung Function With HIV-Related Quality of Life and Health Care Utilization in a High-Risk Cohort.

Background: Chronic respiratory disease represents an important comorbidity for persons living with HIV (PLWH). HIV itself is associated with greater impairment in lung function. We aimed to determine the association between declining lung function and both quality of life (QOL) and health care utilization for PLWH.

Diverse fates of uracilated HIV-1 DNA during infection of myeloid lineage cells.

We report that a major subpopulation of monocyte-derived macrophages (MDMs) contains high levels of dUTP, which is incorporated into HIV-1 DNA during reverse transcription (U/A pairs), resulting in pre-integration restriction and post-integration mutagenesis. After entering the nucleus, uracilated viral DNA products are degraded by the uracil base excision repair (UBER) machinery with less than 1% of the uracilated DNA successfully integrating. Although uracilated proviral DNA showed few mutations, the viral genomic RNA was highly mutated, suggesting that errors occur during transcription.

The effect of HIV infection on longitudinal lung function decline among IDUs: a prospective cohort.

Objective: As survival with HIV infection improves, HIV-infected individuals appear to be susceptible to development of chronic diseases, including restrictive and obstructive lung diseases. We sought to determine the independent association of HIV infection on lung function decline.

Design: Longitudinal analysis of the AIDS Linked to the Intravenous Experience study, an observational cohort of current and former IDUs.
