Abstract
Objective
To perform a meta-analysis evaluating thiamine’s efficacy for sepsis and septic shock to support its clinical use.
Methods
The meta-analysis of randomized controlled studies on patients with sepsis and septic shock evaluated the efficacy of intravenous thiamine. Articles were retrieved from online databases. Qualities of included studies were assessed.
Results
Nine studies enrolling 520 patients were included. Regarding bias risk assessment of studies, two articles were classified as low risk, three were categorized as raising some concerns, and four were identified as high risk. Patients in the thiamine group were significantly associated with decreased proportion of Renal Replacement Therapy (RRT, Odds Ratio [OR = 0.26], p = 0.0007), decreased 24 h lactate level (Mean Difference [MD = -0.35], p = 0.004), and larger 24 h SOFA score change (MD = 1.15, p < 0.00001). No statistical significance was detected in short-time mortality (OR = 0.78, p = 0.18) and 24 h lactate change (MD = 0.09, p = 0.36) between the two groups. In the thiamine-deficient subgroup (2 studies, 51 patients), exploratory analysis indicated a potential short-term mortality reduction with thiamine (OR = 0.18, p = 0.01), though limited by the small sample size.
Conclusion
This meta-analysis preliminarily suggested that thiamine may exert a potential role in improving organ dysfunction among patients with sepsis and septic shock. No significant benefit of thiamine in reducing short-term mortality was observed. It is important to note that the total number of patients included in this meta-analysis is relatively small, which limits the statistical power and external validity of the results.
