Introduction: Because thyroid hormones and liver hormones are so closely linked, thyroid hormone abnormalities can be found in people with liver disorders. Aim: To determine the prevalence of thyroid dysfunction in liver cirrhosis patients. Materials and Methods: This case-control study was carried out in a group of randomly selected liver cirrhosis patients in the Department of Medicine at Rajendra Institute of Medical Sciences (R.I.M.S), Ranchi, Jharkhand (India) between September 2017 to August 2018. The equal number of age (__ampersandsigngt;18 years) and sex-matched cases __ampersandsignamp;controls were included in this study. Radioimmunoassays were used to evaluate early morning fasting blood thyroid-stimulating hormone (TSH), serum total free thyroxine (FT4), and free triiodothyronine (FT3) in 100 index patients with liver cirrhosis who had no history of thyroid disorders. Results: In the cases that were studied, which consisted of cirrhotic patients, males (80%) outnumbered females (20%). The mean age of cases was 47.9 years, and the maximum numbers of the patient were between 41-55 years of age group (47%). Among the cirrhotic patients, the commonest etiology was alcoholic liver disease which contributed to 78% of the total cases studied. The rest of the cases included cirrhotics from other etiologies, which included NAFLD (22%), HBsAg positive individuals (07%), and other cases of cryptogenic origin. The mean FT3, FT4, and TSH values in cases were 2.29__ampersandsignplusmn;0.83; 1.20__ampersandsignplusmn;0.55 __ampersandsignamp; 3.76__ampersandsignplusmn;2.43 respectively __ampersandsignamp; the mean FT3, FT4, and TSH of the control group were 2.95__ampersandsignplusmn;0.52; 1.40__ampersandsignplusmn;0.25 __ampersandsignamp; 2.70__ampersandsignplusmn;0.94 respectively. From these data, we can say that there is significant derangement of thyroid function in liver cirrhosis in favor of hypothyroidism (p__ampersandsignlt;0.05). Conclusion: Hypothyroidism, or abnormalities in circulating thyroid hormone concentrations, is seen in people with alcohol-related liver cirrhosis and is linked to more severe liver disease.
