Objective  To assess the effectiveness and safety of ulinastatin in the treatment of patients with acute pancreatitis.
Methods  A systematic review of randomized controlled trials (RCT) of ulinastatin for acute pancreatitis was performed. Trials were identified by searching The Cochrane Library (issue 3, 2004), MEDLINE, EMBASE (1984-2004) and Chinese Biological Medicine Database (1978-2004), handsearching, and personal contact with pharmaceutical companies. All RCTs comparing ulinastatin with other interventions were included. Two reviewers assessed the quality of each studiy, and extracted data independently. Statisticsal analysis was performed by using RevMan 4.2.
Results  Seventeen trials involving 1 199 patients were included. Most included trials were of poor quality. Only two trials reported death at the end of follow-up. Meta-analysis of 6 RCTs showed that the clinical effective rate of Ulinastatin plus basic treatment group was 93.12% (176/189), and was 73.33% in basic treatment group. A statistic significant difference was found between the two groups (Peto OR 4.29, 95%CI 2.49 to 7.37, P<0.000 01). Compared with basic treatment group, Ulinastatin plus basic treatment group significantly reduced the mean hospitalization (WMD -4.93, 95%CI -7.76 to -2.09, P<0.000 7). Meta-analysis of 2 RCTs showed that the clinical effective rate of Ulinastatin plus basic treatment group was 86.75% (131/151), and was 80.49% (99/123) in other drugs plus basic treatment group. No statistic significant difference was found between the two groups (Peto OR 1.46, 95%CI 1.76 to 2.80, P<0.26). One trial found that comparing with control group (23.5±7.5 days), Ulinastatin group (34.0±6.4 days) significantly reduced the mean hospitalization (P<0.05).The reported severe adverse events of ulinastatin appeared to be rare (7/488, 1.43%).
Conclusion  Ulinastatin appears to be a modality of safe and effective treatment with a favorable trend, but there is no enough evidence to support this conclusion at present as the published trials with poor quality. More trials with enough sample size and scientifically sound methodology are required.
