Background And Aim:
Bacterial infections are among the main causes of death in patients with cirrhosis. While there are unquestionable benefits of using albumin in patients with spontaneous bacterial peritonitis, the benefits of albumin are controversial for those with extraperitoneal infections. The aim was to compare the use of albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections.
Methods:
A systematic review was performed using MEDLINE and Embase databases. Randomized controlled trials comparing albumin associated to antibiotics and antibiotics alone in cirrhotic patients with extraperitoneal infections were considered eligible, as long as at least one of the following outcomes was evaluated: mortality and renal dysfunction. Meta-analysis was performed using the random effects model, through the Mantel-Haenszel method. The study protocol was registered at PROSPERO platform (CRD42018107191).
Results:
The literature search yielded 812 references. Three randomized controlled trials fulfilled the selection criteria and were included in this meta-analysis. There was no evidence of significant difference between the groups regarding mortality in 30 days (risk ratio [RR] = 1.62, 95% confidence interval [CI]: 0.92-2.84, P = 0.09, I2 = 0%) or in 90 days (RR = 1.27, 95% CI: 0.89-1.83, P = 0.19, I2 = 0%). Regarding renal dysfunction, there was also no evidence of significant difference between the groups (RR = 0.55, 95% CI: 0.25-1.19, P = 0.13, I2 = 0%).
Conclusion:
There is no evidence of significant benefits of using albumin for cirrhotic patients with extraperitoneal infections regarding mortality or renal dysfunction.
Insights
Albumin combined with antibiotics does not improve survival or kidney function in cirrhotic patients with extraperitoneal infections. This meta-analysis found no significant benefits for albumin in treating these specific bacterial infections.
Area of Science:
- Hepatology and Infectious Diseases
- Clinical Pharmacology
- Evidence-Based Medicine
Background:
- Bacterial infections are a leading cause of mortality in cirrhosis patients.
- Albumin's benefit is established for spontaneous bacterial peritonitis but debated for extraperitoneal infections.
Purpose of the Study:
- To compare the efficacy of albumin plus antibiotics versus antibiotics alone in cirrhotic patients with extraperitoneal infections.
- To evaluate the impact on mortality and renal dysfunction.
Main Methods:
- Systematic review of randomized controlled trials from MEDLINE and Embase.
- Meta-analysis using a random effects model (Mantel-Haenszel method).
- Inclusion criteria: cirrhotic patients with extraperitoneal infections, comparing albumin + antibiotics vs. antibiotics alone, assessing mortality or renal dysfunction.
Main Results:
- Three randomized controlled trials were included.
- No significant difference in 30-day or 90-day mortality between groups.
- No significant difference in renal dysfunction between groups.
Conclusions:
- Current evidence does not support the use of albumin for cirrhotic patients with extraperitoneal infections.
- Albumin offers no significant benefit regarding mortality or renal dysfunction in this patient population.
