Abstract


Background: Tuberculosis has even been a grave public health problem in Madagascar, one of the main causes responsible for death at the hospital for active and productive people.

Methods: It was a descriptive and analytical retrospective study of patient records admitted for the research of acid-fast bacillus (AFB) pulmonary and extra pulmonary from January 2003 to December 2014 at the microbiology laboratory of the University Hospital Joseph Ravoahangy Andrianavalona (HU-JRA) Antananarivo, Madagascar. We did this study in order to describe the epidemiology of pulmonary and extra pulmonary tuberculosis at the laboratory. All of the requests about researching AFB for bacterial analysis have been received. Incomplete folders have been rejected. Age, sex, clinic information and the results of AFB research have been analyzed.

Results: During 12 years, 1060 requests have been received to research AFB with 89 cases (8.39%) of positivity. Patients were between 9 months and 93 years old. The middle patient age was 41.7 years. Sex-ratio of infected patients was 1.36. There was a significant difference between gender and positive cases (p=0,001). 82 positive cases (93.77%) were pulmonary localization and 7 cases of extra pulmonary (6.23%).

Conclusions: Despite the lack of screening, the high rate of bacillary pulmonary tuberculosis found was one of the great epidemiological importances because of their contagiousness. It is obvious that only health actions cannot solve the problem of tuberculosis.
