Aim:
Our aim was to evaluate the effect of ulinastatin on 28-day mortality in patients who developed multiple organ failure (MOF) related to their acute illness and were admitted to the intensive care unit (ICU).
Methods:
We carried out a retrospective observational study of MOF patients in a general ICU of a tertiary care hospital in Japan from January 2009 to December 2012. The primary outcome was 28-day all-cause mortality. Secondary outcomes were ventilator-free days, ICU-free days, and vasopressor-free days at day 28. We investigated the association between ulinastatin treatment and outcomes using multivariable regression analysis.
Results:
A total of 212 MOF patients were included, 79 (37%) of whom received ulinastatin. The median age was 70 years (interquartile range, 60-77) and median APACHE II score was 25 (interquartile range, 19-29). Overall 28-day mortality was 20%. There were no significant differences between the ulinastatin group and the control group in age, gender, or APACHE II score. The ulinastatin group had higher prevalence of sepsis (44% versus 22%, P = 0.001). Multivariable logistic regression analysis showed that ulinastatin was not associated with 28-day mortality (odds ratio = 1.22; 95% confidence interval, 0.54-2.79). Moreover, ulinastatin did not reduce the mortality in patients with sepsis (odds ratio = 1.92; 95% confidence interval, 0.52-7.13). However, ICU-free days and ventilator-free days was significantly fewer in the ulinastatin group than control group.
Conclusions:
In this retrospective observational study, ulinastatin was not associated with mortality in elderly patients with established MOF, although it might be related to patient's utility.
Insights
Ulinastatin did not reduce 28-day mortality in intensive care unit (ICU) patients with multiple organ failure (MOF). This study found no survival benefit, with fewer ICU-free days in the ulinastatin group.
Area of Science:
- Critical Care Medicine
- Pharmacology
- Organ Failure Research
Background:
- Multiple organ failure (MOF) is a critical condition in intensive care units (ICUs).
- Ulinastatin, a protease inhibitor, is used in some regions for critical illnesses.
- The efficacy of ulinastatin in MOF patients remains under investigation.
Purpose of the Study:
- To evaluate the effect of ulinastatin on 28-day mortality in ICU patients with MOF.
- To assess secondary outcomes including ventilator-free and ICU-free days.
- To investigate ulinastatin's association with mortality in sepsis-related MOF.
Main Methods:
- Retrospective observational study of 212 MOF patients in a Japanese tertiary care hospital (2009-2012).
- Primary outcome: 28-day all-cause mortality.
- Multivariable regression analysis to assess the association between ulinastatin treatment and outcomes.
Main Results:
- Ulinastatin was administered to 37% of patients; no significant baseline differences between groups.
- The ulinastatin group had a higher prevalence of sepsis (44% vs. 22%).
- Ulinastatin was not associated with 28-day mortality (OR 1.22) or sepsis-related mortality (OR 1.92), but was linked to fewer ICU-free and ventilator-free days.
Conclusions:
- Ulinastatin showed no association with reduced mortality in elderly MOF patients.
- The drug was associated with fewer ICU-free and ventilator-free days.
- Further research may be needed to clarify ulinastatin's role and potential utility in specific patient subgroups.
