The Social, Behavioral, and Ethical Modalities of COVID-19 on HIV Care in South Africa: A Systematic Review.

The profound public health impact of the novel outbreak of the SARS-CoV-2 virus in 2019 has been unparalleled in the last century. Rapid spread of the disease and a high death toll fueled the development and global rollout of effective vaccines regardless of the massive inequitable access. However, some public health measures intended to control COVID-19 have had collateral effects on the control of other infectious diseases. In this systematic review, we analyze the impact of the COVID-19 pandemic on efforts to control HIV in South Africa, emphasizing the social, ethical, and behavioral ramifications. The SCOPUS, PubMed, Ovid, PsychINFO, and Cochrane Library databases were searched for publications between March 2020 and January 2022. Of the 854 articles identified, 245 were found duplicated, and 609 were screened, 241 of which were potentially eligible, and 15 of which were ultimately included. Although no studies on the ethical implications were eligible for our study criteria due to insufficient primary data to perform an analysis on, we explored this topic in the Discussion section of this paper. We confirm declines in ART, PrEP, and HIV testing during the initial lockdown period, with slight variations across the South African provinces. Protecting routine services and reducing the disease burden on high-risk nations such as South Africa is imperative moving forward with the pandemic.

Incidence of venous thrombotic events and events of special interest in a retrospective cohort of commercially insured US patients.

OBJECTIVE: To estimate the US incidence of thrombotic events and related rare diagnoses. DESIGN: Claims-based retrospective cohort study of incidence. SETTING: US commercial health insurance administrative claims database. PARTICIPANTS: Adults 25-64 years of age between 2015 and 2019 with a minimum of 12 consecutive thrombosis-free months of continuous enrolment beginning 2014 were selected. MAIN OUTCOMES: Age (10-year intervals) and sex stratum-specific incidence rates per 100 000 person-years were determined for venous thromboembolism (VTE), cerebral venous thrombosis (CVT) and other major venous thrombotic events, and events of special interest, including immune thrombocytopenic purpura (ITP), haemolytic-uremic syndrome (HUS) and heparin-induced thrombocytopenia (HIT). RESULTS: Of 13 249 229 enrollees (half female/male), incidence of venous thromboembolic events (deep vein thrombosis (DVT), pulmonary embolism (PE), CVT or other major venous thrombotic conditions) was 247.89 per 100 000 person-years (95% CI: 245.96 to 249.84). Incidence of VTE was 213.79 with ICD codes alone (95% CI: 211.99 to 215.59) and 129.34 (95% CI: 127.95 to 130.75) when also requiring a filled anticoagulation prescription or an inferior vena cava (IVC) filter. Incidence was 6.37 for CVT (95% CI: 6.07 to 6.69), 26.06 for ITP (95% CI: 25.44 to 26.78), 0.94 for HUS (95% CI: 0.82 to 1.06) and 4.82 for HIT (95% CI: 4.56 to 5.10). The co-occurrence of CVT with either ITP or HIT (diagnoses within 14 days of one another) was 0.090 (95% CI: 0.06 to 0.13). Incidence tended to increase with age and was higher for women under 55. Incidence for CVT, HUS and CVT with ITP or HIT was higher for women in all age groups. Incidence of PE and CVT increased significantly over the 5-year period, while DVT rates decreased. CONCLUSIONS: These results are the first US estimates for the incidence of thrombotic and rare events of interest in a large, commercially insured US population. Findings provide a critically important reference for determining excess morbidity associated with COVID-19 and more generally for vaccine pharmacovigilance.
