From the Guidelines

Ulinastatin 100,000 units should not be used as a first-line treatment for Kawasaki disease due to its unproven effectiveness and the need for additional experience with this agent. The use of Ulinastatin in clinical practice is primarily based on its properties as a human trypsin inhibitor, which has been utilized in Japan as an adjunctive therapy for acute Kawasaki disease 1. However, its effectiveness in this context is unproven, and it is not generally recommended for patients with Kawasaki disease who are refractory to IVIG.

Some key points to consider when evaluating the use of Ulinastatin include:

  • Its mechanism of action involves inhibiting neutrophil elastase as well as prostaglandin H2 synthase at the messenger RNA level 1
  • The evidence level for its use in Kawasaki disease is C, indicating a lack of strong evidence to support its effectiveness 1
  • Other treatments, such as plasma exchange, have also been reported to be effective in patients who are refractory to IVIG, but these treatments also carry risks and are not generally recommended without further evidence 1

In terms of its use in other clinical contexts, Ulinastatin 100,000 units may be considered for the treatment of acute pancreatitis and systemic inflammatory response syndrome (SIRS), although the typical dosage regimen and administration guidelines may vary. The decision to use Ulinastatin should be based on a careful evaluation of the patient's condition and the potential benefits and risks of treatment, taking into account the latest available evidence and clinical guidelines.

From the Research

Appropriate Use of Injection Ulinastatin

The appropriate use of Injection Ulinastatin (100,000 units) in clinical practice can be understood through its application in various medical conditions, particularly in the treatment of acute pancreatitis.

  • Treatment of Acute Pancreatitis: Ulinastatin has been shown to be effective in the treatment of acute pancreatitis, especially in severe cases. A study published in 2013 2 demonstrated that ulinastatin prevents new organ dysfunction and reduces mortality in subjects with severe pancreatitis.
  • Dosage and Administration: The dosage of ulinastatin can vary, but a common dosage is 200,000 IU administered intravenously every 12 hours for 5 days, as seen in the 2013 study 2. However, the safety and tolerability of high-dose ulinastatin (up to 80×10^5 U) have also been evaluated in healthy volunteers, indicating its potential for use at higher doses 3.
  • Prevention of Post-ERCP Pancreatitis: Ulinastatin has also been used to prevent pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). A randomized, controlled trial in 2005 4 found that prophylactic short-term administration of ulinastatin decreases the incidence of pancreatitis and hyperenzymemia after ERCP.
  • Clinical Value in Moderately Severe or Severe Acute Pancreatitis: The early use of ulinastatin in patients with moderately severe or severe acute pancreatitis has been shown to down-regulate the levels of inflammatory factors, reduce the inflammatory response, decrease intra-abdominal pressure, and shorten abdominal pain time 5.
  • Safety and Tolerability: Ulinastatin has been found to be well-tolerated in healthy subjects, with adverse events being mild and not serious 3. In patients with severe acute pancreatitis, ulinastatin treatment was associated with improved outcomes and reduced adverse events compared to the placebo group 2, 6.

Key Considerations

  • The use of ulinastatin should be guided by clinical judgment and the specific needs of the patient.
  • Monitoring for adverse events and adjusting the dosage as necessary is crucial.
  • Further research may be needed to fully understand the potential benefits and risks of ulinastatin in different clinical contexts.
