Why the study?
Obesity and insulin resistance in metabolic syndrome are linked to alterations in thyroid hormones and decreased uric acid excretion, prompting investigation into the association of metabolic syndrome with hypothyroidism and hyperuricemia.
Is Metabolic Syndrome associated with an increased prevalence of hypothyroidism and hyperuricemia in adult outpatients?
Is Metabolic Syndrome associated with an increased prevalence of hypothyroidism and hyperuricemia in adult outpatients?
Metabolic syndrome is significantly associated with an increased prevalence of hyperuricemia and hypothyroidism, suggesting a potential need for routine screening of these conditions in MetS patients.
Background: Metabolic Syndrome (MetS) (Syndrome X, insulin resistance syndrome, MetS) consists of a constellation of metabolic abnormalities which include central obesity, hyperglycemia, insulin resistance, high triglycerides, low high-density lipoprotein (HDL) cholesterol, and hypertension. Obesity is a critical component of MetS. It causes alteration in the thyroid hormones and hyperuricemia. Furthermore, insulin resistance seen in MetS causes decreased uric acid excretion. Aims and Objectives: To study the association of MetS with hypothyroidism and hyperuricemia. Materials and Methods: A cross-sectional study was conducted among patients from the outpatient department of General Medicine, IPGME and R, Kolkata from January 2012 to June 2013. A total of 112 patients, consisting of 53 patients with MetS and 59 patients without MetS were selected. Patients’ history, clinical and laboratory findings were recorded and data were analyzed. Results: Majority (66%) of the patients with MetS were female and the rest were male. The mean Body mass index of patients with MetS was 33.31±4.36 (Mean±SD) kg/m2 and without MetS was 25.21±2.62 (Mean±SD) kg/m2. A significant association was observed between weight, height, waist circumference, fasting blood sugar, HDL value, and MetS (P<0.05). About 39.6% of the patients with MetS had hyperuricemia. The association between MetS and hyperuricemia was found to be significant. Similarly, 45.3% of the patients with MetS had hypothyroidism. This association was also found to be significant. Serum thyroid-stimulating hormone had a minimal correlation with serum uric acid in patients with MetS (correlation coefficient r=0.344), while no correlation was observed between fT3, fT4 with serum uric acid. Conclusion: Increased prevalence of hyperuricemia and hypothyroidism was seen among patients with MetS. More extensive population-based research is needed to support this finding.
