Altered gut microbiota is associated with different immunologic responses to antiretroviral therapy in HIV‐infected men who have sex with men

The association between gut microbiota and immunologic nonresponse among people living with HIV (PLHIV) on antiretroviral therapy (ART) is not well documented. This study aimed to characterize gut microbiota among HIV‐infected men who have sex with men (MSM) with different immunologic responses. We recruited HIV‐infected MSM and HIV‐uninfected MSM (healthy controls, HC) in Guangzhou, June–October 2021. HIV‐infected MSM were grouped into good immunological responders (GIR) (CD4 + T cell count ≥ 350 cells/μL) and poor immunological responders (PIR) (
