Observation on serum prolactin in hepatic cirrhosis.
Serum prolactin assays in patients of hepatic cirrhosis were analysed. Patients with cirrhosis had higher values of serum prolactin (27.2 +/- 5.1 ng/ml in males and 38.4 +/- 4.1 ng/ml in females) as compared to control subjects (p less than 0.05). Majority of patients of cirrhosis with suspected portal-systemic encephalopathy had significantly higher serum prolactin than those without encephalopathy (p less than 0.05). Significantly higher values of serum prolactin on admission had positive correlation with mortality (p less than 0.01). Clinico-biochemical severity of hepatic dysfunction was directly correlated with level of serum prolactin. The present study reveals the possibility of diagnostic and prognostic values of serum prolactin in cirrhosis, specially in clinical/sub-clinical subsets of portal-systemic encephalopathy.
