Comparison of different severity scores in correlating hemoglobin levels with the severity of hepatic decompensation: An observational study.

BACKGROUND

Chronic liver disease is a growing global health problem, leading to hepatic decompensation characterized by an array of clinical and biochemical complications. Several scoring systems have been introduced in assessing the severity of hepatic decompensation with the most frequent ones are Child-Pugh score, model of end-stage liver disease (MELD) score, and MELD-Na score. Anemia is frequently observed in cirrhotic patients and is linked to worsened clinical outcomes. Although studies have explored anemia in liver disease, few have investigated the correlation of hemoglobin level with the severity of hepatic decompensation.

AIM

To determine the relationship between hemoglobin levels and the severity of decompensated liver disease and comparing the strength of this correlation using the Child-Pugh, MELD, and MELD-Na scores.

METHODS

This cross-sectional study was conducted at a tertiary care hospital with 652 decompensated liver disease patients enrolled in the study. Data was collected on demographics, clinical history, and laboratory findings, including hemoglobin levels, bilirubin, albumin, prothrombin time (international normalized ratio), sodium, and creatinine. The Child-Pugh, MELD, and MELD-Na scores were calculated. Statistical analysis was performed using Statistical Package for the Social Sciences version 26, and correlations between hemoglobin levels and severity scores were assessed using Spearman's correlation coefficient.

RESULTS

The study included 405 males (62.1%) and 247 females (37.9%) with an average age of 58.8 years. Significant inverse correlations were found between hemoglobin levels and Child-Pugh, MELD, and MELD-Na scores ( < 0.01), with the MELD scoring system being the strongest correlator among all. One-way analysis of variance revealed significant differences in hemoglobin levels across the severity groups of each scoring system ( = 0.001). Tukey's post hoc analysis confirmed significant internal differences among each severity group.

CONCLUSION

Understanding the correlation between hemoglobin and liver disease severity can improve patient management by offering insights into prognosis and guiding treatment decisions.
