Do Child-Turcotte-Pugh and nutritional assessments predict survival in cirrhosis: A longitudinal study

Cirrhotic patients face heightened energy demands, leading to rapid glycogen depletion, protein degradation, oxidative stress, and inflammation, which drive disease progression and complications. These disruptions cause cellular damage and parenchymal changes, resulting in vascular alterations, portal hypertension, and liver dysfunction, significantly affecting patient prognosis.

To analyze the association between Child-Turcotte-Pugh (CTP) scores and different nutritional indicators with survival in a 15-year follow-up cohort.

This was a retrospective cohort study with 129 cirrhotic patients of both sexes aged > 18 years. Diagnosis of cirrhosis was made by liver biopsy. The first year of data collection was 2007, and data regarding outcomes were collected in 2023. Data were gathered from medical records, and grouped by different methods, including CTP, handgrip strength, and triceps skinfold cutoffs. The prognostic values for mortality were assessed using Kaplan-Meier curves and multivariate binary logistic regression models.

The coefficient for CTP was the only statistically significant variable (Wald = 5.193, P = 0.023). This suggests that with a negative change in CTP classification score, the odds of survival decrease 52.6%. The other evaluated variables did not significantly predict survival outcomes in the model. Kaplan-Meier survival curves also indicated that CTP classification was the only significant predictor.

Although different classifications showed specific differences in stratification, only CTP showed significant predictive potential. CTP score remains a simple and effective predictive tool for cirrhotic patients even after longer follow-up.
