A descriptive study design was deployed. A total of 56 health workers and four service user participants responded to a structured questionnaire (n = 50) or took part in key informant interviews (n = 10) in five high HIV-prevalence provinces. Most participants did not disclose if they were living with HIV, except for four participants who responded to the questionnaire and were selected for being open about living with HIV. Semi-structured interviews were carried out with health workers in key government health facility positions. The questions were standardized and used a Likert scale. Descriptive statistical and thematic analyses were applied to the data. Results show that antiretroviral treatment (ART) has an impact on stigma reduction. Almost half the participants agreed that treatment is reducing levels of HIV stigma. However, fears of exposure of HIV status and labelling and judgemental attitudes persist. No comprehensive stigma reduction policies and guidelines in healthcare facilities were mentioned. Informal flexible systems to deliver HIV services were in place for health workers living with HIV, illustrating how stigma can be quietly navigated. Lack of confidentiality in healthcare facilities plays a role in fuelling disclosure issues and hampering access to testing and treatment. Stigma reduction training needs standardization. Further, codes of conduct for ‘stigma-free healthcare settings’ should be developed.","PeriodicalId":17328,"journal":{"name":"Journal of the International Association of Providers of AIDS Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43071969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given its global impact, it led to a great deal of concern among the approximately 38 million people living with HIV (PWH). Although many governments worked hard to sustain HIV services, often in collaboration with community partners, it soon became clear that PWH faced multiple barriers and challenges to remain engaged in the HIV care continuum. Containment of the global COVID-19 pandemic required that governments implemented multiple strategies, including requirements to shelter-in-place, distancing, and placing restrictions on travel, which may serve as barriers to accessing non-COVID-related healthcare. OnMarch 25, 2020, the government of India announced an initial “lockdown,” due to the global COVID-19 pandemic, which restricted movement, social gatherings and economic activity until May 31. This resulted in many citizens returning to their native homes to shelter with their extended families. It is unknown what impact the lockdowns may have had on the ability of PWH to visit ART clinics, obtain prescription refills or adhere to their regimens. Since successfulmanagement of HIV requires excellent adherence and timely prescription refills to avoid treatment interruptions, real or perceived challenges, including HIV stigma and worries about coronavirus infection may have interfered with this effort.","PeriodicalId":17328,"journal":{"name":"Journal of the International Association of Providers of AIDS Care","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44256306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corticosteroids are the cornerstone of autoimmune diseases treatment, but their use is associated with an increased risk of infections. It is unclear how HIV status affects the risk of infection associated with corticosteroids use. Methods: We conducted a retrospective cohort study from 1991 to 2011, using a medico-administrative database from Quebec. Medical billing codes were used to identify PLWH, and we matched them on age, sex, and index date with up to 4 HIV-negative controls. The exposure of interest was the use of corticosteroids, defined as a systemic corticosteroid dispensation lasting at least 20 days. The outcome of interest was hospitalization for severe infection. Crude and adjusted incidence rates ratios of infection were obtained using a random effect Poisson model, and results were stratified by HIV status. Results: In total, 4798 PLWH were matched to 17 644 HIV-negative controls, among which 1083 (22.6%) PLWH and 1854 (10.5%) HIV-negative controls received at least one course of corticosteroid. The mean duration of corticosteroids use was 4 ± 4.4 months in PLWH and 1.6 ± 5.5 months in HIV-negative controls. The incidence rate ratio (IRR) for infections associated with corticosteroids use was 2.49[1.71–3.60] in PLWH and 1.32[0.71–2.47] in HIV-negative controls (P value for interaction 0.18). The most frequent infections were pulmonary infections (50.4%), followed by urinary tract infections (26%) and opportunistic infections (10.5%). Conclusion: Although our interaction term did not reach significance, the increased risk of infection associated with corticosteroids use was more pronounced in PLWH.
