Summary: | Abstract Introduction: Some authors advise in favor of delayed sampling of intraoperative parathormone testing (ioPTH) during parathyroidectomy in dialysis and kidney-transplanted patients. The aim of the present study was to evaluate the intensity and the role of delayed sampling in the interpretation of ioPTH during parathyroidectomy in dialysis patients (2HPT) and successful kidney-transplanted patients (3HPT) compared to those in single parathyroid adenoma patients (1HPT). Methods: This was a retrospective study of ioPTH profiles in patients with 1HPT, 2HPT, and 3HPT operated on in a single institution. Samples were taken at baseline ioPTH (sampling at the beginning of the operation), ioPTH-10 min (10 minutes after excision of the parathyroid glands), and ioPTH-15 min (15 minutes after excision of the parathyroid glands). The values were compared to baseline. Results: Median percentage values of ioPTH compared to baseline (100%) were as follows: 1HPT, ioPTH-10 min = 20% and ioPTH-15 min = 16%; 2HPT, ioPTH-10 min = 14% and ioPTH-15 min = 12%; 3HPT, ioPTH-10 min = 18% and ioPTH-15 min = 15%. Discussion: The reduction was equally effective at 10 minutes in all groups. In successful cases, ioPTH decreases satisfactorily 10 minutes after parathyroid glands excision in dialysis and transplanted patients, despite significant differences in kidney function. The postponed sampling of ioPTH appears to be unnecessary.
Resumo Introdução: Alguns autores aconselham a favor de se fazer uma amostragem tardia de teste de paratormônio intraoperatório (PTHIO) durante paratireoidectomia em pacientes transplantados renais e em diálise. O objetivo do presente estudo foi avaliar a intensidade e o papel da amostragem tardia na interpretação do PTHIO durante paratireoidectomia em pacientes em diálise (2HPT) e pacientes com transplante renal bem sucedido (3HPT) em comparação com aqueles em pacientes com adenoma único de paratireoide (1HPT). Métodos: Este foi um estudo retrospectivo dos perfis de PTHIO em pacientes com 1HPT, 2HPT, e 3HPT operados em uma única instituição. Foram coletadas amostras de PTHIO basal (amostragem no início da operação), PTHIO-10 min (10 minutos após a excisão das glândulas paratireoides), e PTHIO-15 min (15 minutos após a excisão das glândulas paratireoides). Os valores foram comparados aos resultados basais. Resultados: Os valores percentuais medianos do PTHIO em comparação aos basais (100%) foram os seguintes: 1HPT, PTHIO-10 min = 20% e PTHIO-15 min |
