Abstract

Mortality from human immunodeficiency virus (HIV)–associated tuberculosis (TB) is high, particularly among hospitalized patients. In 433 people with HIV hospitalized with symptoms of TB, we investigated plasma matrix metalloproteinases (MMP) and matrix-derived biomarkers in relation to TB diagnosis, mortality, and Mycobacterium tuberculosis (Mtb) bloodstream infection (BSI). Compared to other diagnoses, MMP-8 was elevated in confirmed TB and in Mtb-BSI, positively correlating with extracellular matrix breakdown products. Baseline MMP-3, -7, -8, -10, and PIIINP were associated with Mtb-BSI and 12-week mortality. These findings implicate MMP dysregulation in pathophysiology of advanced HIV-TB and support MMP inhibition as a host-directed therapeutic strategy for HIV-TB.
