Prevalence and global trends of polypharmacy among people living with HIV: a systematic review and meta-analysis

Background: There has been a rising prevalence of polypharmacy among people living with HIV (PLWH). Uncertainty however remains regarding the exact estimates of polypharmacy among these cohorts of patients. Methods: We conducted a systematic search of PubMed; EMBASE, CROI, Cochrane Database of Systematic Reviews; Science Citation Index and Database of Abstracts of Reviews of Effects for studies between 1 January 2000 and 30 June 2021 that reported on the prevalence of polypharmacy (ingestion of > 5 non-ART medications) among PLWH on antiretroviral therapy regimen (ART). Prevalence of polypharmacy among HIV-positive patients on ART with Clopper–Pearson 95% confidence intervals were presented. The heterogeneity between studies was evaluated using (Formula presented.) and (Formula presented.) statistics. Results: One hundred ninety-seven studies were initially identified, 23 met the inclusion criteria enrolling 55,988 PLWH, of which 76.7% [95% confidence interval (CI): 76.4–77.1] were male. The overall pooled prevalence of polypharmacy among PLWH was 33% (95% CI: 25–42%) (I2 = 100%, τ2 = 0.9170, p < 0.0001). Prevalence of polypharmacy is higher in the Americas (44%, 95% CI: 27–63%) (I2 = 100%, τ2 = 1.0886, p < 0.01) than Europe (29%, 95% CI: 20–40%) (I2 = 100%, τ2 = 0.7944, p < 0.01). Conclusion: The pooled prevalence estimates from this synthesis established that polypharmacy is a significant and rising problem among PLWH. The exact interventions that are likely to significantly mitigate its effect remain uncertain and will need exploration by future prospective and systematic studies. Registration: PROSPERO: CRD42020170071 Plain Language Summary: Background: In people living with HIV (PLWH), what is the prevalence of polypharmacy and is this influenced by sociodemographic factors? Methods and Results: In this systematic review and meta-analysis of 23 studies comprising 55,988 participants, we have for the first time found an estimated polypharmacy pooled prevalence of 33% among PLWH. There was a relatively higher pooled prevalence of polypharmacy among the America’s compared with European cohorts of PLWH. Conclusion: Polypharmacy among PLWH is a rising morbidity that needs urgent intervention both at policy and patient levels of care.This research was supported by the Qatar National Library

Analysis of Hepatitis B virus (HBV) mutations in patients from Western Saudi Arabia with chronic disease

Introduction: Extensive research has provided a link between HBV variants and the clinical complications of liver diseases. This study was performed to further investigate the relationship between HBV variants in preS, S and BCP/PC regions and disease progression in chronic hepatitis B (CHB) cases in Jeddah, Saudi Arabia. Methodology: 182 CHB patients were recruited for this study. HBV DNA was amplified by PCR in the PreS, S, and BCP/PC regions. Sequences were generated from 31 and 26 treated cases in PreS and S regions respectively and from 72 cases in the BCP/PC region. Results: The majority of cases (86.7%) were genotype D. Mutations at preS1-A2922C, X-A1624C and PC-G1887A were detected only in cases with either a high fibrosis score or hepatocellular carcinoma (HCC), while mutations at positions PC-C1982A, PC-G1951T, X-C1628T and X-A1630G were detected more frequently in HCC cases, without reaching statistical significance. Seven deletions were detected in the PreS-region. No deletions were detected in the CCAAT box. The accumulation of mutations per sample in the preS1-2 and S regions were associated with elevated ALT (p < 0.001, 0.001 and 0.001; respectively) and increased fibrosis (p = 0.018, 0.02 and 0.013; respectively). The accumulation of mutations per sample in the BCP/PC region is associated with high viral load. Occult hepatitis B infection (OBI) was identified in 5 samples. Conclusion: Our results add to the knowledge about HBV genotype-D variants. The accumulation of mutations per sample and OBI seem to play a role in the progression of HBV infection. G1896A was associated with the HBeAg negativity. The preS deletions did not play a role in liver disease progression

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P &lt; 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
