Pregnant women (n = 859) in rural Cameroonian prenatal clinics were screened by two rapid human immunodeficiency virus (HIV) antibody tests (rapid tests [RT]) (Determine and Hema-Strip) using either whole blood or plasma. One additional RT (Capillus, HIV-CHEK, or Sero-Card) was used to resolve discordant results. RT results were compared with HIV-1 enzyme immunoassay (EIA) and Western blot (WB) results of matched dried blood spots (DBS) to assess the accuracy of HIV RTs. DBS EIA/WB identified 83 HIV antibody-reactive, 763 HIV antibody-nonreactive, and 13 indeterminate specimens. RT results were evaluated in serial (two consecutive tests) or parallel (two simultaneous tests) testing algorithms. A serial algorithm using Determine and Hema-Strip yielded sensitivity and specificity results of 97.6% and 99.7%, respectively, whereas a parallel RT algorithm using Determine plus a second RT produced a sensitivity and specificity of 100% and 99.7%, respectively. HIV RTs provide excellent alternatives for identifying HIV infection, and their field performance could be monitored using DBS testing strategies.

Background: Hereditary angioedema (HAE) is a rare, autosomal dominant disorder causing swelling attacks in various parts of the body, resulting in impacts on health-related quality of life (HRQoL). The symptoms of HAE and its impacts on HRQoL have been well-documented in adults; however, relatively little is known about the experiences of adolescents with HAE. The objective of this study was to use qualitative interviews to investigate how adolescents experience HAE symptoms and how HAE impacts their HRQoL.

Background: HIV-related stigma remains a key barrier to the attainment of the UNAIDS global goal of ending AIDS by 2030. Due to the social and contextual nature of HIV-related stigma, community-based interventions may be more effective in addressing it. In this review, we synthesized evidence on the effectiveness and features of community-based interventions against HIV-related stigma in Sub-Saharan Africa.

Background: Blood and oral fluid-based HIV self-tests are important for reaching the undiagnosed living with HIV. The study objectives were to evaluate the oral fluid-based OraQuick® HIV Self-Test (HIV-ST) performance in comparison to laboratory reference testing; determine if laypersons can correctly perform the HIV-ST; document if intended users can successfully interpret pre-made contrived positive, negative, and invalid results; and document if intended users can understand the key messages in the product labeling.
Methods: This prospective study enrolled consenting adult intended users of HIV self-testing from six community health centres in four Canadian provinces between June 2022 and January 2024.

Human challenge experiments could accelerate tuberculosis vaccine development. This requires a safe Mycobacterium tuberculosis (Mtb) strain that can both replicate in the host and be reliably cleared. Here we genetically engineered Mtb strains encoding up to three kill switches: two mycobacteriophage lysin operons negatively regulated by tetracycline and a degron domain-NadE fusion, which induces ClpC1-dependent degradation of the essential enzyme NadE, negatively regulated by trimethoprim.

We describe a rare case of spontaneous remission of Pneumocystis jirovecii pneumonia (PCP) in a 42-year-old patient with human immunodeficiency virus (HIV) infection, followed by severe pulmonary nocardiosis. To our knowledge, this is the first report of spontaneous remission of PCP in a completely untreated patient with HIV infection. The patient, a bisexual Japanese man, presented with fever and anorexia and had a history of non-compliance with antiretroviral therapy (ART) for 13 years.
