Background Intrapleural fibrinolytic therapy (IPFT) with streptokinase (STK), urokinase (UK), and alteplase remains a common practice for managing loculated pleural effusions (LPEs). However, very limited data are available on the comparative efficacy of these agents. Methodology We compared the efficacy and safety of intrapleural streptokinase (n = 28) and urokinase (n = 38) in 66 patients with loculated effusions. IPFT was initiated if effusion remained undrained despite the placement of intercostal chest drainage or pigtail catheter. The dose of STK and UK were 250,000 IU twice daily and 100,000 IU once daily, respectively. The volume of fluid drained after IPFT, radiologic response, clinical response, and adverse events were compared between the two groups. Results The mean volume of fluid drained post-IPFT was 1,379 mL in the STK arm and 1,110 mL in the UK arm (p = 0.251). Of the 66 patients, 53 (80.3%) had good clinical response, and 28 (43.7%) had75% resolution of effusion on chest radiographs. The clinical (79% vs. 82%; p = 0.765) and radiologic response rates (39.3% vs. 44.6%; p = 0.568) were similar in both STK and UK arms. Pain was the most common adverse event in both groups. Significantly more patients in the STK arm developed fever (14% vs. 0%, p = 0.030). Treatment-limiting adverse events occurred in five patients. Conclusions IPFT is a safe and effective method for managing patients with LPEs. Although the clinical and radiologic response rates were similar with STK and UK, the latter may be the preferred choice because of its better safety profile and ease of administration (once-daily dose). |
