OBJECTIVE: : to evaluate the benefit of parathyroidectomy in patients on hemodialysis, regarding nutritional and biochemical statuses, body composition and the health-related quality of life. METHODS: : this is a longitudinal study involving 28 hemodialysis adult patients with severe secondary hyperparathyroidism evaluated before and one year after surgery. Inclusion criteria: parathyroid hormone levels exceeding ten times the upper normal range and end-stage renal disease in hemodialysis program. We used the body mass index to classify the nutritional status and the biodynamics analyzer to evaluate the body composition. Biochemical analysis included markers of lipid and bone metabolism. We assessed quality of life with the SF36 (Short Form Health Survey) questionnaire. All individuals underwent total parathyroidectomy with a forearm implant. RESULTS: : there were significant gains in body weight (61.7 vs 66.0 kg, p<0.001), body cell mass (22.0 vs 24.5 kg/m2, p=0.05) and quality of life (p=0.001) after surgery. With respect to bone metabolism, intact PTH, calcium, phosphorus and alkaline phosphatase all stabilized and there were improvements in biochemical parameters such as albumin and hemoglobin. CONCLUSION: : parathyroidectomy improves hemodialysis patient survival and is associated with weight and bone cell mass gain and improvement in health-related quality of life.
