The Epidemiological Aspects of Tuberculosis Patients in a Tertiary Care Medical College Hospital of Bangladesh

Background and Aims: To assess the clinical and socio-demographic characteristics of tuberculosis patients in a tertiary care medical college hospital of Bangladesh. Methods: An observational study was conducted over a period of one year from September 2015 to August 2016 in the Outpatient Department of Jahurul Islam Medical College Hospital and Department of Pathology, Jahurul Islam Medical College, Kishoregonj, The inclusion criteria of the study were pulmonary and extra pulmonary tuberculosis cases receiving antitubercular drugs therapy. Primary data from each patient was included in tuberculosis patient profile form such as age, gender, educational level, annual income in taka, occupational status and selected social habits like smoking, alcohol. Results: Out of 112 patients studied, 50 (44.6%) were male and 62 (55.4%) were female. The majority of patients 69 (61.7%) were in the age group of 15-34 years. Annual family income of 78 (69.6%) patients ranged between 36,000- 1,50,000 taka. In total 112 patients 43 (38.4%) were illiterate and 36 patients (32.2%) were unemployed. 50% of the patients were smoker. The most common sites involved in extrapulmonary tuberculosis were the lymph nodes (38.2%) followed by the pleura (36.4%). The most common symptoms observed in pulmonary tuberculosis patients were cough with expectoration (96.5%) followed by weight loss (80.7%), fever (73.7%) and loss of appetite (54.4%). Conclusion: Prevalence of infection was noticed between PTB and EPTB with age and it was more common in younger age. However, based on our results TB control programme might usefully target young middle age populations for early diagnosis of TB to decrease TB morbidity and mortality.
