Tuberculosis (TB) cases in 1991 showed a higher incidence of extrapulmonary involvement and in-hospital mortality among Human Immunodeficiency Virus-positive (HIV+) patients. This highlights the critical impact of HIV on TB presentation and outcomes.

Area of Science:

  • Clinical Epidemiology
  • Infectious Diseases
  • Public Health

Context:

  • Retrospective study of 53 tuberculosis cases diagnosed in 1991.
  • Observed incidence rate of 4.4 per 1,000 clinical histories.
  • Identified specific patient demographics including Human Immunodeficiency Virus-positive (HIV+) individuals and marginalized illegal immigrants.

Purpose:

  • To analyze the clinical and epidemiological characteristics of tuberculosis cases in a specific center during 1991.
  • To investigate the correlation between HIV status and extrapulmonary involvement in tuberculosis patients.
  • To assess the in-hospital mortality rates in relation to HIV status among tuberculosis patients.

Summary:

  • Fifteen patients (28.3%) were HIV-positive, and five (9.4%) were marginalized illegal immigrants.

  • Extrapulmonary tuberculosis involvement was significantly higher in HIV-positive patients (73%) compared to HIV-negative patients (42%).
  • In-hospital mortality was substantially greater in HIV-positive tuberculosis patients (20%) than in HIV-negative patients (2.6%).
  • Impact:

    • Demonstrates a significant association between HIV infection and increased severity of tuberculosis, evidenced by higher rates of extrapulmonary disease.
    • Highlights the disproportionately high mortality rate among HIV-positive tuberculosis patients, underscoring the need for integrated care.
    • Provides epidemiological data relevant to public health strategies for tuberculosis control, particularly in vulnerable populations.
