A Cross-Sectional Study of Thyroid Dysfunction in Patients Suffering from Liver Cirrhosis in a Tertiary Care Hospital in Bengaluru, India
BACKGROUND Thyroid abnormalities are seen in most of the patients suffering from liver cirrhosis. Cirrhosis of the liver is the major cause of morbidity and mortality worldwide. Cirrhosis plays a vital role in the thyroid hormone metabolism and thyroid hormone circulation by producing thyroid binding globulin. Hence, it is seen that the thyroid dysfunction is associated with the severity of liver disease. We wanted to study the changes in the levels of thyroid hormones in patients suffering from alcoholic liver cirrhosis. METHODS In this cross-sectional study, 50 patients who were admitted to the IP department and ICU of General Medicine Department of Akash Hospital, Devanahalli, for symptoms of cirrhosis of liver were evaluated for their thyroid profile along with other relevant investigations. RESULTS Among the 50 patients studied, 43 were male and 7 were female. 17 patients had an increase in their thyroid stimulating hormone (TSH). These patients also had a significant association with various LFT parameters such as indirect bilirubin, AST, ALT, APS, and GGT. These 17 patients who had increase in TSH also had associated hepatic complications such as - jaundice (41 %), hepatic encephalopathy (35.29 %), bleeding varices (29.4 %), and portal hypertension (82.35 %). CONCLUSIONS Thyroid abnormalities are not uncommon in patients with cirrhosis. Hypothyroidism is the most common abnormality that was detected. Rate of complications is also high in patients with elevated levels of TSH. A fair amount of suspicion is required for detecting thyroid abnormalities in patients suffering from cirrhosis.
