High Sensitive C-Reactive Protein and Lipid Profile Alteration In Subclinical Hypothyroidism for Cardiovascular Risk Assessment

Background: The purpose of this study was to investigate the association of subclinical hypothyroidism with High sensitive C-reactive protein and lipid profile which can predispose to development of Cardiovascular disease.

Methods: This hospital-based comparative cross-sectional study was conducted for a period of six months. A total of 71 patients with subclinical hypothyroidism and 37 healthy control subjects were enrolled for the study. Thyroid hormones, lipid profile, hs- CRP were measured and lipid variables were used to calculate lipid indices. Student t-test were used to compare means and Spearmans correlation was done to determine the association between variables. ROC curve analysis was used to determine the diagnostic value of tests.

Results: Out of 71 cases and 37 control, majority had female preponderance (71.8% in case and 83.8% in control). The mean values between case and control groups for High sensitive C-Reactive Protein, Atherogenic index of plasma, Lipoprotein combined index and non-High Density Lipoprotein cholesterol were statistically significant. There was positive correlation between Thyroid Stimulating Hormone and High sensitive C-Reactive Protein r=0.492, p 0.001, Atherogenic index of plasma and Thyroid Stimulating Hormone r=0.430, p 0.001, Lipoprotein combined index and Thyroid Stimulating Hormone (r=0.269, p =0.005), Thyroid Stimulating Hormone and non-High Density Lipoprotein cholesterol (r=0.308, p=0.001) and Atherogenic Index and Low Density Lipoprotein r= 0.712, p 0.001 with weak correlation with statistical significance as per Spearmans correlation. Area under ROC curve for High sensitive C-Reactive Protein indicated it as a positive biomarker for cardiovascular risk assessment.

Conclusions: Our findings shows that sch patients are more at risk of cvd and hs-crp contributes as a significant marker, thus requiring timely intervention. Lipid indices and AIP must be determined even in patients with a normal lipid profile to improve atherogenic risk.
