Purpose of Review: The aim of this report is to summarize the conclusions of the II Regional Meeting on Histoplasmosis in the Americas held in Manaus, Brazil, on March 22–24, 2019. Recent Findings: Persons living with advanced HIV are at high risk for developing histoplasmosis. Clinical signs and symptoms of this disease are often non-specific, making it difficult to establish a diagnosis. Although with the recent technological advances, in vitro diagnostics and medicines for histoplasmosis are often not available in many regions around the world. In addition, histoplasmosis is often not included in HIV care and treatment programs, resulting in inadequate health system planning and missed opportunities to save lives. Summary: The II Regional Meeting on Histoplasmosis in the Americas gathered a multidisciplinary audience. Developed recommendations to be included in the WHO guidelines for diagnosis and treatment of histoplasmosis in advanced HIV were the product of this meeting, and guidelines are aimed to be published in early 2020. © 2019, This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply.

Background: Cryptococcal meningitis is a leading cause of death amongst people living with HIV. However, routine cryptococcal antigen (CrAg) screening was not in the national guidelines in Eswatini. Objectives: A cross-sectional study was conducted between August 2014 and March 2015 to examine CrAg prevalence at Mbabane Government Hospital in Eswatini. Methods: We collected urine and whole blood from antiretroviral-therapy-naïve patients with HIV and a cluster of differentiation 4 (CD4) counts < 200 cells/mm3 for plasma and urine CrAg lateral flow assay (LFA) screening at the national HIV reference laboratory. Two CD4 cut-off points were used to estimate CrAg prevalence: CD4 < 100 and < 200 cells/mm3. Sensitivity and specificity of urine CrAg LFA was compared to plasma CrAg LFA. Results: Plasma CrAg prevalence was 4% (8/182, 95% confidence interval [CI]: 2–8) amongst patients with CD4 counts of < 200 cells/mm3, and 8% (8/102, 95% CI: 3–15) amongst patients with CD4 counts of < 100 cells/mm3. Urine CrAg LFA had a sensitivity of 100% (95% CI: 59–100) and a specificity of 80% (95% CI: 72–86) compared with plasma CrAg LFA tests for patients with CD4 < 200 cells/mm3. Forty-three per cent of 99 patients with CD4 < 100 were at World Health Organization clinical stages I or II. Conclusion: The prevalence of CrAg in Eswatini was higher than the current global estimate of 6% amongst HIV-positive people with CD4 < 100 cell/mm3, indicating the importance of initiating a national screening programme. Mechanisms for CrAg testing, training, reporting, and drug and commodity supply issues are important considerations before national implementation.
