A study on CABI score in correlation with comorbidity, microbiological profile and early mortality among pulmonary TB patients with bacterial co-infection

Tuberculosis (TB)-related deaths are preventable, yet research on co-infections primarily focuses on human immunodeficiency virus (HIV)-positive patients, leaving a gap for HIV-negative individuals. Early clinical monitoring is vital for reducing mortality, but research lacks clear links between mortality scoring, microbiological data, and prognostic factors. Despite early mortality being absent among our participants, we found prognostic markers such as comorbidity, smear-negative TB, high bacterial load, and bacterial co-infection correlated with elevated CABI scores.
