Setting: Süreyyapaşa Centre for Chest Diseases and Thoracic Surgery, Istanbul, Turkey.
Objective: To report the frequency of treatment side effects in cases of multidrug-resistant (MDR-TB) tuberculosis.
Design: A retrospective review of the medical records of 263 patients who received individualised treatment for MDR-TB between April 1992 and June 2004.
Results: One or more side effects developed in 182 cases (69.2%). These effects led the clinicians to withdraw one or more drugs from the treatment regimen in 146 cases (55.5%). Side effects observed most frequently included: ototoxicity (41.8%), psychiatric disorders (21.3%), gastrointestinal disturbance (14.0%), arthralgia (11.4%), epileptic seizures (9.9%), hepatitis (4.5%), and dermatological effects (4.5%). At the time of analysis, treatment was successful in 204 (77.6%) cases. Fifty-nine patients (22.4%) had poor outcomes.
Conclusion: Timely and aggressive management of drug side effects means that high side effect rates in MDR-TB treatment need not compromise success rates.
