ObjectivesTo describe the implementation of screening for cryptococcal antigenaemia by point-of-care (POC) serum cryptococcal antigen (CrAg) lateral flow assay, measure the prevalence and factors associated with serum cryptococcal antigenaemia in the routine programmatic setting.DesignCross-sectional study.SettingSeventeen publicly funded antiretroviral therapy (ART) centres in Mumbai, India.ParticipantsSerum CrAg screening was offered to all adolescents (>10 years of age) and adults with advanced HIV disease (AHD) (CD4 <200 cells/mm3or with WHO clinical stage III/IV) regardless of symptoms of cryptococcal meningitis.Primary and secondary outcome measuresThe primary outcome was to describe the implementation of serum CrAg screening and secondary outcome was to measure the prevalence of serum cryptococcal antigenaemia and its risk factors.ResultsA total of 2715 patients with AHD were tested for serum CrAg by POC assay. Of these, 25 (0.9%) had a CrAg positive result. Among CrAg-positive patients, only one had symptoms. Serum CrAg positivity was 3.6% (6/169) and 1.6% (6/520) among those presenting with CD4 <100 cells/mm3in the treatment naïve and treatment experienced group, respectively. On multivariable analysis, CD4 count <100 cells/mm3(OR: 2.3, 95% CI 1.01 to 5.3; p=0.05) and people living with HIV who were treatment naïve (OR: 2.5, 95% CI 1.04 to 6.0; p=0.04) were significantly associated with a positive serum CrAg result. Lumbar puncture was obtained in 20/25 patients within 4 days (range: 1–4 days) of positive serum CrAg result and one person was confirmed to have meningitis. All serum CrAg-positive patients who had a negative cerebrospinal fluid CrAg were offered pre-emptive therapy.ConclusionsImplementation of a POC CrAg assay was possible with existing ART centre staff. Initiation of pre-emptive therapy and management of cryptococcal antigenaemia are operationally feasible at ART centres. The Indian National AIDS Control Programme may consider reflexive CrAg screening of all AHD patients with CD4 <100 cells/mm3.

Background It is important to understand the current internet-related sexual behaviours of high-risk groups such as men who have sex with men (MSM). We designed the present study to understand the types of online/mobile apps used by MSM and male-to-female transgendered people/hijras [TGH] in Mumbai, India. We also compared the internet-related ‘partner seeking’ and ‘sexual behaviours’ in MSM and TGH in Mumbai, India. Methods This is a cross-sectional analysis of secondary data collected (April to June 2020) from 8582 MSM and 4163 TGH from five targeted intervention programmes each in Mumbai, Maharashtra, India. Data on demographics, years of association with the intervention, number and type of online/mobile apps used, sexual behaviours including partners from virtual space and non-virtual (physical) space, group sex, attending parties, mobility for sexual partners, and HIV status were collected. Results MSM were more likely to have mobile phone (88% vs 51%, p < 0.001) and internet access over the phone (78% vs 27%; p < 0.001) compared with TGH. The common apps used by MSM were Grindr (48%), Facebook (42%), and Blued (36%). MSM were more likely to have partners from virtual space (91% vs 67%; p < 0.001). A higher proportion of MSM had attended parties (28% vs 2%; p < 0.001), had group sex (16% vs 6%; p < 0.001), and were mobile for sex (25% vs 4%). MSM and TGH who had partners from virtual space were significantly more likely to report ‘missed a condom at least once during penetrative sex in the past one week’ (17% vs 12%; p<0.001). In HIV positive MSM, group sex, parties, and mobility for sex, were only in those who reported partners from the virtual space. Conclusions Internet-based interventions for MSM should be incorporated in the existing targeted intervention programme and outreach workers should be trained in virtual outreach services. Among TGH, given the low reach and use of smartphones and apps, internet-based interventions may not be such a useful option, and the existing physical targeted intervention programmes should be strengthened.
