title: [Tertiary hyperparathyroidism during chronic kidney failure under dialysis treatment. Apropos a clinical case].
abstract: The authors describes a case of tertiary hyperparathyroidism (HPTH) in a uremic patient on intermittent dialysis treatment: the term refers to an adenoma with ensuing uncontrolled parathormone (PTH) secretion rate arising on the ground of hyperstimulated hypertrophied parathyroid glands. The syndrome was heralded clinically by bone pain, psychiatric disorder and biochemically by increased levels of calcium and alkaline phosphatase (AP), while parathormone (PTH), did not change from basal very high levels as commonly found in uraemic patients. As hypercalcemia in the hemodialyzed is an infrequent finding the only alternative explanation could have been hypercalcemic secondary HPTH related to hyperplastic autonomous parathyroids. For no clinical and laboratory findings as well as US findings and double scintigraphy (99mTc and 201mTl) may suggest differential diagnosis the patient underwent total parathyroidectomy which actually revealed an adenoma of the left superior parathyroid gland. Bone pain and psychiatric disturbances disappeared and now get well on chronic dialysis treatment and 1.25-OH Vit D3 supplement.
