Objectives:1)To study level of serum highdensity lipoprotein (HDL) level in subclinical
hypothyroidism andeuthyroid patients 2) To study association between serum HDL and
serum TSH in subclinical hypothyroidism.
Materials and Methods:The study was hospital based observational study which
included15 patients of subclinical hypothyroidism and 15 patient’s euthyroid after
diagnosis based on theirserum thyroid stimulating hormone (TSH), freeT3 and freeT4
level done during their regular visit to outpatient medicine department.Bloodsample
was collected of all the participants after an overnight (12hours) fasting and serum high
density lipoprotein levels was estimated. Statisticalanalysis was done on collected data.
Results: Participants with euthyroidism and subclinical hypothyroidism showed no
significant difference in serum high density lipoprotein levels and a negative correlation
was found between serum TSH and serum HDL level in subclinical hypothyroidism
Conclusions:Thyroid hormones have various effects on lipid metabolism.The
effects of subclinical hypothyroidism on serum HDL level were not statistically
significantand a negative correlation between serum TSH and serum HDL which was
suggestive of linear decrease in serum HDL with increase in serum TSH levels.

Introduction: The levels of thyroid hormone & thyroid binding proteins are altered in patients of
chronic liver disease. Our aim was to assess the serum freeT3 and serum free T4 levels, in alcohol
related liver disease and to find the correlation between thyroid hormone levels and severity of
alcohol related liver disease.
Methods: A cross sectional study, with a sample size of 50, was done to assess the serum free T3
andserum free T4 levels of thyroid function andto correlate them with prognostic factors of alcohol
related liver disease, i.e.MELD-Na - which is derived by adding serum sodium to the original Model
for End-Stage Liver Disease (MELD) score and Maddrey’sDiscriminant Function (DF).Statistical
analysis was done with - Chi-Square test, p value <0.001 was considered as statistically significant.
Results: Of the 50 patients, low serum free T3 levels were found in 29 patients, among them15
patients had DF<32; 14 patients had DF>32(p value <0.001), and 14 patients had MELD-Na<24.50;
15 patients had MELD-Na >24.50(p value <0.006). Low serum freeT4 levels were found in 12
patients, among them 4 patients had DF<32;8 patients had DF >32 (p value <0.001), and 8 patients
had MELD <24.50; 4 patients had MELD >24.50(p value <0.825).
Conclusion: Significant decrease in the serum free T3 levels was found in patients of alcohol related
liver disease with Maddrey’sDiscriminant Function >32 and MELD-Na >24.50 (both prognostic
markers of more severe liver disease). Hence, low serum free T3 level can be used as a prognostic
indicator of severity of alcohol related liver disease.
