Tuberculosis in Visceral Leishmaniasis-Human Immunodeficiency Virus Coinfection: An Evidence Gap in Improving Patient Outcomes?

Visceral leishmaniasis (VL)-human immunodeficiency virus (HIV) coinfection remains a major problem in Ethiopia, India, and Brazil. Tuberculosis (TB), a treatable factor, could contribute to high mortality (up to 25%) in VL-HIV coinfection. However, the current evidence on the prevalence and clinical impact of TB in VL-HIV coinfection is very limited. In previous reports on routine care, TB prevalence ranged from 5.7% to 29.7%, but information on how and when TB was diagnosed was lacking.
