ABSTRACT
BACKGROUND:
Mycobacterium tuberculosis (M.TB) causes a wide spectrum of clinical diseases. The prevalence of TB is different in various parts of Iran and throughout the world. The present study aimed to determine the clinical epidemiology and paraclinical findings of TB.METHODS:
A cross-sectional study was conducted from 2008 to 2013. Patient demographic, clinical, and radiologic characteristics, picked up from the TB patient's files, were collected using a standard questionnaire format. Data was entered and analyzed using the SPSS version 16 statistical software and P value < 0.05 was considered statistically significant.RESULTS:
Out of 212 patients enrolled in this study 62% were male and the mean age was about 50 years old. 98.6% were Iranian, and 46.2% were rural. Prevalence of smear-positive TB was 66.4%. Prevalence of positive PPD was 50.7% with no significant difference between HIV-positive and -negative patients (P = 0.8). Prevalence of diabetes mellitus was 17%. 36% of the patients had history of smoking and about 29.3% were addicted to narcotics. Cough was the most common symptom (94.5%) and 84% had sputum. 15 cases (7%) had extrapulmonary TB. The mean time between the onset of symptoms and admission was 46.5 days. The delay for admission between urban and rural populations was not significantly different (P = 0.68); but for those who were in prison, the delay was significant (P = 0.02). About 46% of the patients had cavitary lesions in CXRs.CONCLUSION:
Timely diagnosis of TB especially in prisoners by understanding its most important epidemiologic characteristics and clinical features can help to make an early treatment and prevent spread of mycobacteria and their complications.
