Potentially inappropriate medications in older adults living with HIV

OBJECTIVES

We assessed the prevalence of potentially inappropriate medication (PIM) among older (≥ 65 years) people living with HIV (O-PLWH) in the region of Madrid.

METHODS

We analysed the dispensation registry of community and hospital pharmacies from the Madrid Regional Health Service (SERMAS) for the period between 1 January and 30 June 2017, looking specifically at PIMs according to the 2019 Beers criteria. Co-medications were classified according to the Anatomical Therapeutic Chemical (ATC) classification system.

RESULTS

A total of 6 636 451 individuals received medications. Of these individuals, 22 945 received antiretrovirals (ARVs), and of these 1292 were O-PLWH. Overall, 1135 (87.8%) O-PLWH were taking at least one co-medication, and polypharmacy (at least five co-medications) was observed in 852 individuals (65.9%). A PIM was identified in 482 (37.3%) O-PLWH. Factors independently associated with PIM were polypharmacy [adjusted odds ratio (aOR) 7.08; 95% confidence interval (CI) 5.16-9.72] and female sex (aOR 1.75; 95% CI 1.30-2.35). The distribution of PIMs according to ATC drug class were nervous system drugs (n = 369; 28.6%), musculoskeletal system drugs (n = 140; 10.8%), gastrointestinal and metabolism drugs (n = 72; 5.6%), cardiovascular drugs (n = 61; 4.7%), respiratory system drugs (n = 13; 1.0%), antineoplastic and immunomodulating drugs (n = 10; 0.8%), and systemic anti-infectives (n = 2; 0.2%). Five drugs accounted for 84.8% of the 482O PLWH with PIMs: lorazepam (38.2%), ibuprofen (18.0%), diazepam (10.2%), metoclopramide (9.9%), and zolpidem (8.5%).

CONCLUSIONS

Prescription of PIMs is highly prevalent in O-PLWH. Consistent with data in uninfected elderly people, the most frequently observed PIMs were benzodiazepines and nonsteroidal anti-inflammatory drugs . Targeted interventions are warranted to reduce inappropriate prescribing and polypharmacy in this vulnerable population.

Bacterial translocation and clinical progression of HCV-related cirrhosis in HIV-infected patients

The aim of the study was to evaluate whether bacterial translocation (BT) predicts the clinical outcome in HIV/HCV-coinfected patients with compensated cirrhosis. A cohort of 282 HIV/HCV-coinfected patients with cirrhosis and no previous liver decompensation (LD) was recruited. Serum levels of the DNA sequences encoding the well-conserved 16S rRNA subunit (16S rDNA), the lipopolysaccharide (LPS) and soluble CD14 (sCD14) at diagnosis of cirrhosis were measured. Primary endpoint was the emergence of the first LD and/or death of any cause. Secondary endpoints were LD, liver-related death (LRD) and death of any cause. After a median (Q1-Q3) follow-up of 51 (27-72) months, 67 patients (24%; 95% CI: 19-29) developed their first LD or died during follow-up. Baseline levels of 16S rDNA, LPS and sCD14 were not associated with the probability of developing the primary endpoint of the study. The mean (SD) survival time free of LD and/or death according to levels of 16S rDNA (<83, 83-196, 197-355, >355 [copies/μL]) was 78 (5), 72 (5), 81 (4) and 82 (4) months, respectively (P = .5). The corresponding figures for LPS (<0.1, 0.1-0.6, 0.6-1.5, > 1.5 [IU/mL]) were 76 (5), 71 (5), 77 (5) and 81 (4) months, respectively (P = .4). Baseline levels of BT serum markers were not associated with any of the secondary endpoints analysed in the study. Thus, BT does not seem to be a relevant predictor of clinical outcome in HIV/HCV-coinfected patients with compensated cirrhosis.
