Factors determining the mortality in cirrhosis patients with invasive candidiasis: A systematic review and meta-analysis.

Unlabelled: The impact of invasive candidiasis (IC) on the outcomes in the non-conventional high-risk cirrhosis population is poorly characterized. Therefore, we reviewed the outcomes and their influencing factors in cirrhosis patients with IC. PubMed, Embase, Ovid, CINHAL, and Web of Science were searched for full-text observational studies describing mortality due to IC in cirrhosis. We did a systematic review and random-effects meta-analysis to pool the point-estimate and comparative-odds of mortality. The estimate's heterogeneity was explored on sub-groups, outliers-test, and meta-regression. We evaluated the asymmetry in estimates on funnel plot and Eggers regression. Quality of studies was assessed on the New-Castle Ottawa scale. Of 3143 articles, 13 studies (611 patients) were included (good/fair quality: 6/7). IC patients were sick with a high model for end-stage liver disease (MELD: 27.0) and long hospital stay (33.2 days). The pooled-mortality was 54.7% (95% CI: 41.3--67.5), I2: 80%, P < 0.01. Intensive care unit (ICU) admission (P < 0.001), site of infection; viz. peritonitis and candidemia (P = 0.014) and high MELD of cases (P = 0.029) were predictors of high mortality. The odds of mortality due to IC was 4.4 times higher than controls and was 8.5 and 3.3 times higher than non-infected, and bacterially-infected controls. Studies in ICU-admitted (OR: 5.0) or acute-on-chronic liver failure (ACLF, OR: 6.3) patients had numerically higher odds of mortality than all-hospitalized cirrhosis patients (OR: 4.0). In conclusion, substantially high mortality is reported in cirrhosis patients with IC. ICU admission, ACLF, high MELD, peritonitis, and candidemia are key factors determining high mortality in cirrhosis patients with IC.

Lay Summary: We report a high mortality rate of 55% in patients with liver cirrhosis and invasive candidiasis. Higher odds (4.4 times) of death, especially in patients with ACLF (6.3 times) or ICU admission (5.0 times) were seen. Candida peritonitis and candidemia are associated with high mortality in cirrhosis.
