The clinical relevance of systemic inflammatory response syndrome in patients with cirrhosis and hepatic encephalopathy is still unknown, despite the fact that SIRS is linked to the advancement of cirrhosis. HE presenting with mental disorders is a common and sometimes lethal symptom among individuals with decompensated cirrhosis. Thus, this study aimed to report the prevalence of SIRS in cirrhotic patients with HE and explore how SIRS affects prognosis in this patient group.
A total of 161 hospitalized patients with cirrhosis and HE had their clinical data examined. Among the patients of this study, 40 (24.8%) passed away while in the hospital, and 60 (37.3%) acquired SIRS. The following were risk variables for hospitalization-related deaths based on univariate Cox analysis: SIRS, WBC, neutrophils, neutrophil/lymphocyte ratios (NLR), alanine aminotransferase (ALT), serum total bilirubin (TBIL), aspartate aminotransferase (AST), international normalized ratio, creatinine (Cr), and a MELD score > 18.
The significant independent risk variables were SIRS and a MELD score more than 18 (hazard ratio 4.758, 2.539; 95% CI 2.115–10.703, 1.210–5.331; P < 0.001, P < 0.05, respectively). For SIRS scores of 0, 1, 2, 3, and 4, the corresponding 28-day survival rates were 95.8%, 89.6%, 61.1%, 37.5%, and 12.5% (P < 0.001).
The death rate for patients with a MELD score of < 18 was 30% for those with SIRS and 7% for those without. Mortality was 62% in individuals with SIRS and 16% in patients without SIRS when a MELD score was greater than 18 (P < 0.001). Mortality among uninfected individuals was 43% for those with SIRS and 4% for those without. The death rate among infected patients was 53% among those who satisfied SIRS diagnostic criteria and 19% among those who did not (P < 0.001).
Overall, this research discovered that SIRS is a prevalent, independent risk factor for mortality among hospitalized LC patients with HE, whether or not there is an infection. These findings highlight the significance of HE as an early risk indicator for LC patients' in-hospital HE-related deaths.
