Multidrug-resistant tuberculosis (MDR-TB) has surged in New York, complicating the AIDS and TB epidemics. Urgent action is needed for faster diagnosis, new treatments, and improved patient care environments.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Epidemiology

Background:

  • Tuberculosis (TB) remains a significant global health challenge.
  • The rise of multidrug-resistant tuberculosis (MDR-TB) presents a critical threat to public health efforts.
  • Co-epidemics of Acquired Immunodeficiency Syndrome (AIDS) and TB have been observed.

Purpose of the Study:

  • To investigate the increasing prevalence of multidrug-resistant tuberculosis (MDR-TB) at Bellevue Hospital Center.
  • To identify demographic and clinical characteristics of patients with drug-resistant TB.
  • To highlight the complex interplay between TB, AIDS, and MDR-TB epidemics.

Main Methods:

  • Retrospective review of laboratory susceptibility test results for 4,681 TB cases over 20 years (1971-1991).

  • Analysis of combined resistance to isoniazid and rifampin.
  • Review of medical records for 100 patients diagnosed with drug-resistant TB.

    • Main Results:

    • A significant increase in MDR-TB was observed, with combined isoniazid and rifampin resistance rising from 2.5% in 1971 to 16% in 1991.
    • Drug-resistant TB patients were predominantly young (under 40), minority, male, jobless, undomiciled, with high rates of drug abuse and HIV infection.
    • Higher rates of resistance were noted for individual anti-TB drugs.

    Conclusions:

    • The epidemics of AIDS and TB are compounded by a third epidemic of MDR-TB.
    • Urgent attention is required for rapid MDR-TB diagnosis and development of novel therapeutic regimens.
    • Addressing the social and hospital care environments is crucial for managing MDR-TB patients.
