A Study of Thyroid Profile and Lipid Profile in Patients with Chronic Kidney Disease with or without Hemodialysis in a Tertiary Care Hospital.

BACKGROUND Chronic kidney disease (CKD), due to increasing frequency and prevalence, has become one of the leading public health issues. The Kidney Disease Outcome Quality Initiative (KDOQI) defines CKD as kidney injury or a reduction in the glomerular filtration rate (GFR) to <60 mL/minute/1.73 m2 for at least 3 months. This study aims to compare the effects of decreased renal function on thyroid profile and lipid profile in CKD patients. MATERIALS AND METHODS This is a prospective cross-sectional observational study conducted among the patients attending Outpatient Department/Inpatient Department (OPD/IPD) at the School of Medical Sciences & Research, Sharda Hospital, Greater Noida, Uttar Pradesh, India, in known cases of CKD, irrespective of the treatment/stage of CKD. All patients of >18 years of age with CKD were included in the study. RESULT A total of 200 patients who met the inclusion criteria were included after obtaining detailed informed consent, of which 100 were cases and 100 were controls. The mean age of patients in the study was 47.74 years, with the mean age in patients with CKD 52 years, and the control was 43 years. The mean level of triglycerides (TGs) was significantly higher among the cases, and the high-density lipoprotein (HDL) was significantly lower among cases compared to controls (p < 0.05). Pearson's correlation between thyroid-stimulating hormone (TSH) with creatinine showed a weak albeit significant positive association (r = 0.200; p < 0.05). CONCLUSION Our study shows a higher incidence of alteration in thyroid profile and dyslipidemia among the patients with CKD compared to controls. There is a necessary need to screen routinely for hypothyroidism and dyslipidemia among patients with CKD. Importantly, thyroid hormone levels and their effects on the progression of CKD have not been studied exhaustively.
