Extrapulmonary tuberculosis in Oklahoma, 1965 to 1973
The American Review of Respiratory Disease
|May 11, 1975
Summary
Extrapulmonary tuberculosis cases in Oklahoma did not decrease from 1965-1973. Recent cases showed more bacteriologic confirmation and disproportionately affected nonwhites, particularly with tuberculous meningitis.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Extrapulmonary tuberculosis (EPTB) represents a significant global health challenge.
- Understanding trends in EPTB is crucial for effective public health interventions.
- Previous studies have indicated declining tuberculosis rates, but EPTB trends require specific investigation.
Purpose of the Study:
- To analyze the trends and characteristics of extrapulmonary tuberculosis cases reported in Oklahoma between 1965 and 1973.
- To identify demographic and diagnostic patterns within EPTB cases over the study period.
Main Methods:
- Retrospective analysis of 370 reported cases of extrapulmonary tuberculosis.
- Data collected from the Oklahoma State Department of Health records.
- Comparison of EPTB case distribution with overall tuberculosis diagnoses in the population.
Main Results:
- The annual incidence of reported EPTB cases showed no significant decrease during the 1965-1973 period.
- A higher proportion of EPTB cases in recent years (within the study period) had bacteriologic confirmation.
- Nonwhite populations were disproportionately represented in newly diagnosed EPTB cases, especially for tuberculous meningitis, lymphadenitis, and miliary tuberculosis.
Conclusions:
- The persistent incidence of EPTB suggests a need for further investigation into contributing factors.
- Increased bacteriologic confirmation in later years may indicate improved diagnostic practices.
- The higher burden of EPTB in nonwhite populations highlights potential disparities in healthcare access or disease susceptibility.
