New World Leishmania spp. infection in people living with HIV: concerns about relapses and secondary prophylaxis

This study investigated patients with HIV/ATL and HIV/VL to describe the outcome of leishmaniasis in patients assisted at a referral hospital of Brazilian midwestern region. Patients with HIV/ATL (n = 21) mainly presented cutaneous diseases (76.2%) with an overall relapse rate of 28.57% after treatment, whereas HIV/VL (n = 28) patients accounted for 17.5% of the cases. The counts of CD4+ T cells and CD8+ T cells and the CD4+/CD8+ cell ratios at diagnosis or relapses were not significantly different between relapsing and non-relapsing patients. Patients with HIV/ATL or HIV/VL showed high levels of activation markers in CD4+ and CD8+ T cells. The regular use of highly active antiretroviral therapy (HAART) and viral load at the time of diagnosis did not influence the relapse rates. Relapses occurred in 36.4% (4/11) of the patients with HIV/VL receiving secondary prophylaxis and in 5.9% (1/17) of the patients who did not receive secondary prophylaxis (p = 0.06). These data are relevant for the therapeutic management of the patients coinfected with HIV/Leishmania.PMID:34562423 | DOI:10.1016/j.actatropica.2021.106146
