Abstract

People with HIV (PWHIV) are likely to need therapies for comorbidities as they age. We assessed risk of drug-drug interactions (DDIs) in PWHIV. The Climate-HIV electronic recording system was used to cross-sectionally analyse records from PWHIV aged ≥ 18 years attending four UK HIV units with a current antiretroviral (ARV) prescription in February 2018. Antiretroviral and non-ARV medications were categorized by clinical significance of DDIs (University of Liverpool DDI tool). Potential DDIs were predicted using treatment guidelines for commonly recorded comorbidities. Among 4630 PWHIV (44% female), 41% were ≥ 50 years old. The average number of non-ARV comedications increased from < 1 for patients aged ≤ 24 years to > 5 for patients aged ≥ 75 years; 65% were taking one or more non-ARV comedications. The median (interquartile range) number of non-ARVs was 1 (0-2) and 2 (1-5) for those aged < 50 and ≥ 50 years, respectively. Common comorbidities/concurrent health conditions occurred more frequently in patients aged ≥ 50 years vs. < 50 (53% vs. 34%). Boosted protease inhibitors were associated with the highest proportion of contraindicated comedications; dolutegravir and raltegravir had the fewest. For non-ARVs, sildenafil and que...Continue Reading
