Parathyroid Disorders and Treatments

Background Primary hyperparathyroidism ( PHPT ) is associated with high cardiovascular morbidity. The aim of the present study was to explore the relationship of leptin and adiponectin levels with cardiovascular risk factors and anthropometric parameters in patients with PHTP with and without metabolic syndrome ( MS ). Methods A total of 62 patients with PHPT were enrolled. Weight, blood pressure, basal glucose, insulin, total cholesterol, low‐density lipoprotein cholesterol, high‐density lipoprotein cholesterol, triglycerides, insulin, HOMA‐R , intact parathormone, vitamin D , calcium, leptin, and adiponectin levels were measured in fasting condition. Results Prevalence of MS with ATP III definition was 32.3% (20 patients; 15 females (75%) and 5 males (25%)) and 67.7% patients without MS ( n = 42 patients; 35 females (83.3%) and 7 males (16.7%)). In the analysis with leptin as dependent variable, the weight and HOMA‐R levels remained in the model ( F = 9.2; P < 0.05), with an increase of 1.31 ( CI 95%: 0.24–2.31) ng/ml with each one unit of HOMA‐R and an increase of 0.4 ( CI 95%: 0.01–0.84) ng/ml with each 1 kg of weight. In a second model with adiponectin as dependent variable, the HOMA‐R and HDL ‐cholesterol levels remained in the model ( F = 7.37; P < 0.05), with a decrease of −0.62 ( CI 95%: 0.01–1.1) ng/ml with each one point of HOMA‐R and an increase of 0.18 ( CI 95%: 0.04–0.38) ng/ml with each 1 mg/dl of HDL ‐cholesterol. In the multivariate, PTH I was not associated with other variables. Conclusion There was a high prevalence of MS —32.3% of patients with PHPT presented an MS . Serum levels of leptin and adiponectin are not related with PTH I, vitamin D , and calcium levels in patients with PHPT . J. Clin. Lab. Anal. 26:398‐402, 2012. © 2012 Wiley Periodicals, Inc.
