Background:
Tuberculosis is one of the most common causes of hospitalisation in patients with HIV. Despite this, hospital outcomes of patients with this co-infection have rarely been described since antiretroviral therapy became widely available.
Methods:
Prospective cohort study of HIV-infected adult patients hospitalised with TB in six referral hospitals in Medellin, Colombia, from August 2014 to July 2015.
Results:
Among 128 HIV-infected patients hospitalised with tuberculosis, the mean age was 38.4 years; 79.7% were men. HIV was diagnosed on admission in 28.9% of patients. The median CD4 + T-cell count was 125 (±158 SD) cells/µL. Only 47.3% of patients with a known diagnosis of HIV upon admission were on antiretroviral therapy, and only 11.1% had a tuberculin skin test in the previous year. Drug toxicity due to tuberculosis medications occurred in 11.7% of patients. Mean length of stay was 23.2 days, and 10.7% of patients were readmitted. Mortality was 5.5%.
Conclusions:
Hospital mortality attributable to tuberculosis in patients with HIV is low in reference hospitals in Colombia. Cases of tuberculosis in HIV-infected patients occur mainly in patients with advanced HIV, or not on antiretroviral therapy, despite a known diagnosis of HIV. Only one of every 10 patients in this cohort had active screening for latent tuberculosis, possibly reflecting missed treatment opportunities.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
