Abstract
INTRODUCTION: Pakistan ranks 4th among 22 multidrug resistant tuberculosis (MDR-TB) high burden countries. The increasing rate of MDR-TB in Pakistan underscores the importance of effective treatment programs of drug-resistant TB. Clinical management of MDR-TB requires prolonged multidrug regimens that often cause adverse events (AEs). MATERIALS AND METHODS: This retrospective case series study include all patients who were enrolled for MDR-TB treatment during January 2014 till April 2015 at Programmatic Management of Drug Resistant TB (PMDT) unit at tertiary care hospital, Lady Reading Hospital (LRH) Peshawar Pakistan. In this study we sought to ascertain the occurrence of treatment related adverse events and factors associated with these events. Here we also examined the frequency of and reasons for changing drug regimens. We further sought to determine whether the occurrence of adverse events negatively impacts the treatment outcome and management of adverse effects without requiring the discontinuation of MDR-TB therapy. RESULT: At the time of analysis final outcomes of all 200 enrolled patients exist. Among these 52.5% were females and (81.5%) were aged ≤ 44 years. Among study cases 155 (77.2%) experienced at least one adverse event during treatment. The most commonly reported events were psychiatric issues (70%) whereas the less common was skin rashes (7.5%). A change in drug dose due to adverse events occurred in 16.5% cases, while 13.5% cases had at least one drug discontinued temporarily. Younger age and lung cavities at baseline were positive association with occurrence of adverse events. Association was also found between adverse events and treatment outcomes (OR 0.480, 0.236-0.978, p= 0.041). CONCLUSIONS: Adverse events were prevalent among MDR-TB patients treated at PMDT-LRH Peshawar. All patients who were younger aged and cavitory lungs should be closely monitored for occurrence of adverse events.
