Could a drug calm the immune storm in severe abdominal infections?

This study tests whether ulinastatin, a drug that reduces inflammation, can help patients with severe abdominal infections. The infection often causes the immune system to overreact, leading to organ failure and high risk of death. Researchers will give patients either a low or high dose of ulinastatin or a placebo for five days, alongside standard care, and measure changes in immune and inflammatory markers. The goal is to see if ulinastatin can restore immune balance and improve outcomes.
