Lower Mortality Rates from Cryptococcosis in Women and Whites with Human Immunodeficiency Virus in the United States.

Cryptococcosis is an opportunistic mycotic infection often found in pigeon droppings and other bird excrement. This serious disease is often fatal and, not unexpectedly, far more common in patients with immune deficiency, including those with human immunodeficiency virus (HIV). It has been hypothesized that women with cryptococcosis and HIV have a more favorable mortality experience than men. In addition, the availability of highly active anti-retroviral therapy (ART) for HIV in the United States (US) has been associated with greater racial disparities in mortality. The US Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (WONDER) database afforded a unique opportunity to explore mortality rates due to cryptococcosis by gender and race in the US among patients with HIV from 1999 to 2016. Mortality rate ratios from cryptococcosis were significantly lower in women and whites with HIV. These descriptive data lead to the formulation of hypotheses requiring testing in analytic studies designed a priori to do so and pose clinical and public health challenges in reducing mortality from cryptococcosis in patients with HIV.
