Underdiagnosis of iron deficiency anaemia in HIV-infected individuals: a pilot study using soluble transferrin receptors and intensive bone marrow iron stores to improve the diagnosis.

AIM: We compared soluble transferrin receptors (sTfR), serum ferritin, mean cell volume (MCV) of red cells and the sTfR-ferritin index with the intensive method bone marrow trephine (BMT) iron stores in the diagnosis of iron deficiency anaemia (IDA) in Human Immunodeficiency Virus (HIV)-positive hospitalised participants. METHODS: In this cross-sectional study, we recruited hospitalised HIV-positive and coronavirus of 2019 (COVID-19)-negative adults with anaemia who required a bone marrow examination as part of their diagnostic workup. We measured the full blood count, ferritin, sTfR and assessed iron using the intensive method in Haemotoxylin and Eosin (H&E)-stained BMT core biopsies of consenting participants. RESULTS: Of the 60 enrolled participants, 57 were evaluable. Thirteen (22.80%) had IDA on H&E BMT iron stores assessment, and 44 (77.19%) had anaemia of chronic diseases (ACD). The sTfR and the sTfR-ferritin index had sensitivities of 61.54% and 53.85%, respectively, for IDA diagnosis. The sensitivity and specificity of ferritin was 7.69% and 92.31%, respectively. The sTfR and sTfR-ferritin index's diagnostic specificity was relatively low at 46.15% and 38.46%, respectively. CONCLUSION: In this pilot study in HIV-positive participants, the prevalence of iron deficiency using the BMT assessment was low. Both the sTfR and the sTfR-ferritin index had a better quantitative correlation to bone marrow iron stores when compared with the MCV and ferritin and, may be more accurate surrogate markers of IDA.

The HIV Cascade of Care and Service Utilisation at Sex Work Programmes Among Female Sex Workers in South Africa.

Female sex workers (FSWs) in South Africa experience a uniquely high prevalence of HIV. We describe the HIV cascade of care (CoC) in FSWs in South Africa, and explored service utilisation at sex work programmes. A cross-sectional, study enrolled FSWs across 12 sites in South Africa. Participants were recruited using chain-referral method. Inclusion criteria: ≥ 18 years, cis-gender female, sold/transacted in sex, HIV positive. 1862 HIV positive FSWs were enrolled. 92% were known positive, 87% were on antiretroviral treatment (ART). Of those on ART, 74% were virally suppressed. Younger FSWs were significantly less likely to be on ART or virally suppressed. Female sex workers using HIV services from specialised programs were 1.4 times more likely to be virally suppressed than non-program users. The pre-COVID-19 pandemic HIV CoC amongst FSWs in South Africa shows striking improvement from previous estimates, and approaches achievement of 90:90:90 goals.

Sexual Risk Behaviors Among Youth in Soweto, South Africa During the COVID-19 National Lockdown.

BACKGROUND: Assessment of sexual risk behavior among youths is crucial for HIV prevention strategies. However, the literature on sexual behavior in youth during the COVID-19 pandemic is sparse. AIM: This study surveyed sexual risk behavior among youth in Soweto, South Africa during the COVID-19 pandemic national lockdown in 2020. METHODS: We conducted a cross-sectional telephonic survey on socio-demographics and HIV risk behaviors among youth aged 18-24 years during level 3 of the lockdown. Frequencies and their respective percentages were determined for categorical variables and stratified by biological sex. Chi-square analysis was used to compare categorical variables. All data were analyzed using SAS software. OUTCOMES: A risk assessment for HIV questionnaire was used to assess sexual risk behaviors. Also, substance use was assessed through a developed yes/no questionnaire. RESULTS: Of the 129 participants, 83.0% (n = 107) had a sexual partner; 52% of those who had a sexual partner were females, 60.7% (65/107) had one current sexual partner and 39.2% (42/107) had more than 1 sexual partner. Most reported sex within 1 week (54.2%, n = 58/107) and 30.8% within a month (30.8%, n = 33/107). Sex was with a dating partner (86.0%, n = 92/107) and 63% used a condom during last sexual contact. Males were more likely than females to have one-night stand sexual partners (23.5% vs 7.1%; P = .0176), make weekly changes in partners (17.7% vs 5.4%; P = .0442) and used condoms with their partners (92.2% vs 53.6%; P < .0001) during last sexual contact. The majority reported alcohol use (69.0%, n = 89/129). Males were more likely than females to use alcohol on a weekly basis (21.4% vs 6.4%; P = .0380). About 55.9% had penetrative sex under the influence of substances. CLINICAL TRANSLATION: This study gives an insight to the sexual risk behaviors among young people which is crucial for HIV prevention interventions. STRENGTH & LIMITATIONS: This was the first study investigating sexual behavior in youth during the COVID-19 pandemic. The main limitations of this study relate to the sample size and sampling strategy. As the sample was not representative of the population of young people in Soweto and South Africa, the results cannot be generalized. However, the findings have relevance for future research in HIV prevention for young people in other settings in South Africa. CONCLUSIONS: Interventions on promoting sexual health and reducing HIV risk behavior such as sex following alcohol consumption in young people are needed, especially during a pandemic such as COVID-19.
