Aims: Polypharmacy increase the risk of drug–drug interactions (DDIs) in the elderly population living with human immunodeficiency virus (HIV). Several expert databases can be used to evaluate DDIs. The aim of the study was to describe actual DDIs between antiretroviral drugs and comedications in an elderly population and to compare grading of the DDIs in 3 databases. Methods: All treatments of HIV‐infected subjects aged 65 years and older were collected in 6 French HIV centres. Summary of Product Characteristic (SPC), French DDI Thesaurus (THES), and Liverpool HIV DDI website (LIV) were used to define each DDI and specific grade. DDIs were classified in yellow flag interaction (undefined grade in SPC and THES or potential weak interaction in LIV), amber flag interaction (to be considered/precaution of use in SPC and THES and potential interaction in LIV) and red flag interaction (not recommended/contraindication in SPC and THES and do not administer/contraindication in LIV). Results: Among 239 subjects included, 60 (25.1%) had at least 1 DDI for a total of 126 DDIs: 23/126 red flag DDIs were identified in 17 patients. All these 23 DDIs were identified in LIV. THES and SPC missed 6 and 1 red flag DDIs, respectively. Seven of 23 red flag DDIs were identified in the 3 databases concomitantly. Conclusion: Polypharmacy is frequent in this elderly HIV population leading to DDI in a quarter of the subjects. The discrepancies between databases can be explained by differences in analysis methods. A consensus between databases would be helpful for clinicians. [ABSTRACT FROM AUTHOR] more...

Introduction Sleep disturbances are frequently reported in HIV-infected patients but there is a lack of large studies on prevalence and risk factors, particularly in the context of current improved immuno-clinical status and use of the newest antiretrovirals (ARV). Method Cross-sectional study to evaluate the prevalence and factors associated with sleep disturbance in adult HIV-infected patients in six French centres of the region 'Pays de la Loire'. Patients filled a self-administered questionnaire on their health behaviour, sleep attitudes (Pittsburgh Sleep Quality Index PSQI), quality of life (WHO QOL HIV BREF questionnaire) and depression (Beck depression Inventory (BDI)-II questionnaire). Socio-demographic and immunovirologic data, medical history, ARVs were collected. Results From November 2012 to May 2013, 1354 consecutive non-selected patients were enrolled. Patients' characteristics were: 73.5% male, median age 47 years, active employment 56.7%, France-native 83% and Africa-native 14.7%, CDC stage C 21%, hepatitis co-infection 13%, lipodystrophy 11.8%, dyslipidemia 20%, high BP 15.1%, diabetes 3%, tobacco smokers 39%, marijuana and cocaine users, 11.7% and 1.7% respectively, and excessive alcohol drinkers 9%. Median (med) duration of HIV infection was 12.4 years, med CD4 count was 604/mm3; 94% of Patients were on ARVs, 87% had undetectable viral load. Median sleeping time was 7 hours. Sleep disturbances (defined as PSQI score >5) were observed in 47% of the patients, more frequently in female (56.4%) than in male (43.9%) (p<0.05) and moderate to serious depressive symptoms (BDI score>19) in 19.7% of the patients. In multivariate analysis, factors associated with sleep disturbances (p<0.05) were depression (odds ratio [OR] 4.6; 95% confidence interval [CI] 3.2-6.8), male gender (OR 0.7; CI 0.5-0.9), active employment (OR 0.7; CI 0.5-0.9), living single (OR 1.5; CI 1.2-2.0), tobacco-smoking (OR 1.3; CI 1.0-1.8), duration of HIV infection (>10 vs. <10 y.) (OR 1.5; CI 1.1-2.0), ARV regimen containing nevirapine (OR 0.7; CI 0.5-0.9) or efavirenz (OR 0.5; CI 0.3-0.7). Conclusions Prevalence of sleep disturbances is high in this HIV population and roughly similar to the French population. Associated factors are rather related to social and psychological status than HIV infection. Depression is frequent and should be taken in care to improve sleep quality. [ABSTRACT FROM AUTHOR] more...
