Abstract
Background:
In India, cirrhosis is becoming a growing concern, leading to an unmet need for new non-invasive markers to assess the severity of liver disease. Serum prolactin is one such marker.
Aim:
To determine the association between serum prolactin, the severity of liver cirrhosis, and its complications such as ascites, hepatic encephalopathy, and esophageal varices.
Methods:
This cross-sectional study involved 117 patients with liver cirrhosis. They were evaluated for some complications such as ascites, esophageal varices, and hepatic encephalopathy, as well as for severity by using the Child-Turcotte-Pugh (CTP) score. Serum prolactin levels were measured, and their relationship with both the severity and complications of liver cirrhosis was determined. A P value of < 0.05 was considered significant.
Results:
The mean age of the patients was 48.3 ± 12.08 years, and the majority (80.3%) were males. Seventy-one percent of the patients had elevated serum prolactin levels (>19.40 ng/mL). Elevated serum prolactin was found in approximately 95.0% and 86.8% of patients with hepatic encephalopathy and ascites, respectively. The median serum prolactin levels were significantly associated with esophageal varices grades (P = 0.043) and hepatic encephalopathy (P < 0.001). The sensitivity and specificity of serum prolactin for predicting severe CTP scores were 81.6% and 91.2%, respectively, with a diagnostic accuracy of 87.2%. On multivariate regression analysis, ascites (AOR = 3.8, 95%CI = 1.29–10.98, P = 0.015), hepatic encephalopathy (AOR = 6.1, 95%CI = 0.68–53.78, P = 0.012), CTP class B (AOR = 5.9, 95%CI = 1.39–24.68, P = 0.016), and CTP class C (AOR = 13.4, 95%CI = 2.25–82.21, P = 0.004) were significantly associated with elevated serum prolactin levels.
Conclusion:
There was a significant association between serum prolactin levels and CTP classes, esophageal varices, ascites, and hepatic encephalopathy in patients with liver cirrhosis.
