Frequency of Smear Positive Pulmonary Tuberculosis in Prisoners of Central Prison of Hamadan in 1999

All factors that produce active tuberculosis are present in prisoners. The over crowded condition of most prisons coupled with HIV infection, malnutrition and IV drug abusing among prisoners may lead to a substantial tuberculosis epidemic in the prison system . Between January and March 1999 we carried out an active case finding survey in Hamadan central prison, Iran, through the WHO tuberculosis control program. We interviewed prisoners and those with cough of at least 3 weeksʹ duration were screened by sputum-smear microscopy. If sputum smear was negative after 10 days antibiotic administration and after three consecutive negative smear , prisoner underwent chest radiography. 106 of 1 115 prisoners were screened; (all men , mean age 33.2years). 79 prisoners (74.5%) had addiction to opium. The most common route of opium were inhalation (70 cases), oral (20 cases), inhalation-oral (15 cases) and parentral (4 cases). Two screened prisoners (1.88%) had pulmonary tuberculosis with positive smear and were not taking anti tuberculosis drugs and had addiction to heroin. 67 (53.7%) of 106 screened prisoners underwent chest radiography. In 2 prisoners the chest radiograph suggested active tuberculosis, in 2 prisoners hilar lymph node calcification was seen due to old tuberculosis and in 2 prisoners suggested calcification and scar of old tuberculosis in pulmonary apices. As a result, the frequency of smear positive pulmonary tuberculosis in central prison of Hamadan was significant and must pay attention to it.
