Invasive fungal infections pose a severe threat in unconventional immunocompromised hosts such as cirrhosis. Herein we review the impact of invasive aspergillosis (IA) on the prognosis of cirrhosis patients. An electronic search for full-text articles describing IA in cirrhosis was conducted and the disease outcomes and mortality (point-estimate and comparative risk) were pooled on random-effects meta-analysis. Of 4127 articles, 11 studies (9 with good/fair and 2 with poor quality) were included. IA was associated with high disease severity and multi-organ failures in cirrhosis. The pooled-mortality of IA was 81.8% (95%CI: 64.3-91.8, I2 = 59%, p<0.01). Estimate's-heterogeneity (I2) was explored through sub-groups, meta-regression, and influential diagnostics. Mortality estimates were higher among subgroups of acute-on-chronic liver failure (ACLF, 86.4%) and intensive care unit (ICU)-admitted patients (84.0%). The odds of mortality related to IA were 8.9 times higher than controls and much higher in ACLF (OR: 22.5) and ICU-admitted patients (OR: 36.4). The odds of mortality in IA were 4.1, 12.9, and 48.6 times higher than bacterial, no-fungal infections, and no-infection controls. There was no asymmetry in mortality-estimates or odds ratios and mortality in IA was high irrespective of country of origin, site of infection, proven or probable category, and quality of study. Thus, IA is associated with very high mortality in cirrhosis patients, especially in ACLF and ICU-admitted patients. Intensive research is needed for the rapid diagnosis and treatment of IA in cirrhosis.
