J Coll Physicians Surg Pak Jan ;19(3):162-4.

Objective: To determine the frequency of common risk factors for multi-drug resistant tuberculosis in patients presented at a tertiary care hospital, Peshawar. Study Design: Cross-sectional, observational study. Place and Duration of Study: Pulmonology Department, Khyber Teaching Hospital, Peshawar, from December 2006 to October 2007. Methodology: Patients with positive AFB culture and sensitivity results and found resistant to both rifampicin and isoniazid with or with resistance to other first line anti-tuberculosis drugs, were recruited from both Pulmonology Ward and Outpatient Department (OPD). Informed verbal consent was taken and a questionnaire administered to all participants of the study. Information regarding demographics, education status, occupation, monthly household income, AFB C/S, details of past history of tuberculosis and family history of TB or Multi-Drug Resistant (MDR-TB) was recorded. Data was analyzed on SPSS version 11. Results: A total of 30 patients of MDR-TB were interviewed. Male (n=17) and female (n=13) ratio was 1.3:1. Mean age was 34.2±15.3 years. Ninety-two percent female and 52.9% male were uneducated. In 56.7%, monthly income was less than 5000 rupees and in 40% between 5000-10,000 rupees. All patients had previous history of Antituberculous Treatment (ATT), in which 20% had undertaken ATT course once, 53.3% twice and 26.7% thrice in the past. In the study group, 13 (43.3%) patients had not completed their first ATT course and 11 of them were receiving ATT from a general practitioner (GP) at that time. Seven (23.3%) patients had family history of TB but no one had documented MDR-TB in the family. Resistance to RH was present in all patients; moreover, 56.7% had resistance to RHEZ+S. Conclusion: The most common factors in the study group were previous history of tuberculosis, repeated courses of ATT, prescribed by different clinicians and unsupervised treatment by a GP during the initial course of ATT.
