Hypoparathyroidism (HypoPT) is a rare disease characterized by low calcium and inappropriately low circulating parathormone levels. We present the case of a 25-year-old high-performance athlete male, with history of HypoPT after total thyroidectomy for papillary thyroid carcinoma (T3 N1b M0) two years before, who was referred to our clinic for symptomatic hypocalcemia. The patient reported serum calcium average levels of 7mg%, presented symptoms of hypocalcemia at rest and had multiple hospital admissions. First, standard treatment was optimized by calcium supplementation up to 12g/d and active vitamin D, not showing clinical or biochemical improvement. Malabsorption and complications of chronic HypoPT were ruled out. The 36-Item Short Form Health Survey (SF-36) demonstrated an impaired quality of life (QoL). Full-length recombinant human parathyroid hormone [rhPTH(1-84)] therapy was started with 50μg/d subcutaneous, and later adjusted to 75μg/d and the oral treatment gradually decreased. Currently, he is asymptomatic, with serum calcium levels above 9mg%, without receiving oral medication. He performs sports activity and shows marked improvement in quality of life according to SF-36 questionnaire.
