초록

Background: Intrapleural fibrinolytic therapy (IPFT) has been used as an effective agent since 1949 for managing complicated pleural effusion and empyema. Several agents, such as streptokinase, urokinase (UK), and recombinant tissue plasminogen activator (rt-PA), have been found to be effective with variable effectiveness. However, a head-tohead controlled trial comparing the efficacy of the most frequently used agents, i.e., UK and rt-PA (alteplase) for managing complicated pleural effusion has rarely been reported. Methods: A total of 50 patients were randomized in two intervention groups, i.e., UK and rt-PA. The dose of rt-PA was 10 mg, and that of UK was 1.0 lac units. UK was given thrice daily for 2 days, followed by clamping to allow the retainment of drugs in the pleural space for 2 hours. rt-PA was instilled into the pleural space twice daily for 2 days, and intercostal drainage was clamped for 1 hour. Results: A total of 50 patients were enrolled into the study, of which 84% (n=42) were males and 16% (n=8) were females. Among them, 30 (60%) patients received UK, and 20 (40%) patients received alteplase as IPFT agents. The percentage of mean±standard deviation changes in pleural opacity was -33.0%±9.9% in the UK group and -41.0%±14.9% in the alteplase group, respectively (p=0.014). Pain was the most common adverse side effect, occurring in 60% (n=18) of the patients in the UK group and in 40% (n=8) of the patients in the alteplase group (p=0.24), while fever was the second most common side effect. Patients who reported early (within 6 weeks of onset of symptoms) showed a greater response than those who reported late for the intervention. Conclusion: IPFT is a safe and effective option for managing complicated pleural effusion or empyema, and newer agents, such as alteplase, have greater efficacy and a similar adverse effect profile when compared with conventional agents, such as UK.
