Despite the recent rollout of Isoniazid Preventive Therapy (IPT) to prevent TB in people living with HIV in South Africa, adherence and completion rates are low. To explore barriers to IPT completion in rural KwaZulu-Natal, South Africa, we conducted individual semi-structured interviews among 30 HIV patients who had completed or defaulted IPT. Interview transcripts were analyzed according to the framework method of qualitative analysis. Facilitators of IPT completion included knowledge of TB and IPT, accepting one’s HIV diagnosis, viewing IPT as similar to antiretroviral therapy, having social support in the community and the clinic, trust in the healthcare system, and desire for health preservation. Barriers included misunderstanding of IPT’s preventive role in the absence of symptoms, inefficient health service delivery, ineffective communication with healthcare workers, financial burden of transport to clinic and lost wages, and competing priorities. HIV-related stigma was not identified as a significant barrier to IPT completion, and participants felt confident in their ability to manage stigma, for example by pretending their medications were for unrelated conditions. Completers were more comfortable communicating with health care workers than were defaulters. Efforts to facilitate successful IPT completion must include appropriate counseling and education for individual patients and addressing inefficiencies within the health care system in order to minimize patients’ financial and logistical burden. These patient-level and structural changes are necessary for IPT to successfully reduce TB incidence in this resource-limited setting.
Key Points Question Does COVID-19 convalescent plasma (CCP), compared with placebo, improve the clinical status of hospitalized patients with COVID-19 requiring noninvasive supplemental oxygen? Findings In this randomized clinical trial including 941 patients, based on the World Health Organization 11-point Ordinal Scale for Clinical Improvement, CCP did not benefit 468 participants randomized to CCP compared with 473 randomized to placebo from April 2020 to March 2021. However, in exploratory analyses, CCP appeared to benefit those enrolled from April to June 2020, the period when most participants received high-titer CCP and were not receiving remdesivir and corticosteroids at randomization. Meaning In this trial, CCP did not meet prespecified outcomes for efficacy, but high-titer CCP may have benefited hospitalized patients with COVID-19 early in the pandemic when other treatments were not in use, suggesting a heterogenous treatment effect over time.
Unrecognized transmission is a major contributor to ongoing TB epidemics in high-burden, resource-constrained settings. Limitations in diagnosis, treatment, and infection control in health-care and community settings allow for continued transmission of drug-sensitive and drug-resistant TB, particularly in regions of high HIV prevalence. Health-care facilities are common sites of TB transmission. Improved implementation of infection control practices appropriate for the local setting and in combination, has been associated with reduced transmission. Community settings account for the majority of TB transmission and deserve increased focus. Strengthening and intensifying existing high-yield strategies, including household contact tracing, can reduce onward TB transmission. Recent studies documenting high transmission risk community sites and strategies for community-based intensive case finding hold promise for feasible, effective transmission reduction. Infection control in community settings has been neglected and requires urgent attention. Developing and implementing improved strategies for decreasing transmission to children, within prisons and of drug-resistant TB are needed.
With a 19.2% HIV prevalence, South Africa has the largest HIV/AIDS epidemic worldwide. Despite a recent scale-up of public sector HIV resources, including community-based programs to expand HIV care, suboptimal rates of antiretroviral therapy (ART) initiation and adherence persist. As community stakeholders with basic healthcare training, community health workers (CHWs) are uniquely positioned to provide healthcare and insight into potential strategies to improve HIV treatment outcomes. The study goal was to qualitatively explore the self-perceived role of the CHW, unmet CHW needs, and strategies to improve HIV care in rural KwaZulu-Natal, South Africa. Focus groups were conducted in May-August 2014, with 21 CHWs working in Msinga subdistrict. Interviews were audio-recorded, transcribed, and translated from Zulu into English. A hybrid deductive and inductive analytical method borrowed from grounded theory was applied to identify emergent themes. CHWs felt they substantially contributed to HIV care provision but were inadequately supported by the healthcare system. CHWs' recommendations included: (1) sufficiently equipping CHWs to provide education, counseling, social support, routine antiretroviral medication, and basic emergency care, (2) modifying clinical practice to provide less stigmatizing, more patient-centered care, (3) collaborating with traditional healers and church leaders to reduce competition with ART and provide more holistic care, and (4) offsetting socioeconomic barriers to HIV care. In conclusion, CHWs can serve as resources when designing and implementing interventions to improve HIV care. As HIV/AIDS policy and practice evolves in South Africa, it will be important to recognize and formally expand CHWs' roles supporting the healthcare system.
