Concentraciones persistentemente elevadas de hormona paratiroidea tras resección quirúrgica curativa de hiperparatiroidismo primario: prevalencia y posibles marcadores predictivos.

Abstract

Introducción: El hiperparatiroidismo primario es una enfermedad frecuente en Endocrinología, caracterizada por una producción autónoma excesiva de hormona paratiroidea (PTH). Su causa más frecuente es un adenoma único (80-90%) y tratamiento curativo es la resección quirúrgica. A pesar de la normalización de la calcemia tras la intervención un porcentaje de pacientes presenta concentraciones persistentemente elevadas de PTH. Este estudio busca determinar la prevalencia de esta condición y evaluar posibles factores predictivos. Material y método: Estudio observacional, descriptivo y retrospectivo en pacientes intervenidos de HPTP por adenoma único en el Hospital General Universitario de Elche entre 2019 y 2023. Se han incluido 39 pacientes con criterios de curación postquirúrgica. Se han analizado variables clínicas y bioquímicas pre y postoperatorias a los 3 y 12 meses de la cirugía, evaluando su relación con la persistencia de PTH elevada. Resultados: A los 3 meses de la cirugía, el 61,5% de los pacientes presentaban niveles elevados de PTH, mientras que a los 12 meses, el 54,8% mantenían esta alteración. Se encontró que los pacientes con niveles preoperatorios de PTH superiores a 84 pg/mL tenían una mayor tendencia a mantener valores elevados postcirugía (p=0,001). Además, niveles elevados de calcio en orina de 24 horas prequirúrgicos se asociaron con una mayor probabilidad de normalización de la PTH tras la cirugía (p=0,007). Conclusión: El 54,8% de los pacientes intervenidos de HPTP por adenoma único en este estudio presentaron persistencia de PTH elevada tras la cirugía. Las concentraciones de PTH prequirúrgicas altas y la hipercalciuria preoperatoria fueron factores relevantes en la evolución postquirúrgica. Se necesitan estudios de seguimiento para evaluar las implicaciones clínicas a largo plazo de esta condición.

Introduction: Primary hyperparathyroidism is a common endocrinological disease characterized by excessive autonomous production of parathyroid hormone (PTH). Its most frequent cause is a single adenoma (80-90%), and the curative treatment is surgical resection. Despite the normalization of calcium levels after surgery, a percentage of patients present persistently elevated PTH concentrations. This study aims to determine the prevalence of this condition and evaluate possible predictive factors. Materials and Methods: This is an observational, descriptive, and retrospective study conducted on patients who underwent surgery for primary hyperparathyroidism due to a single adenoma at the General University Hospital of Elche between 2019 and 2023. A total of 39 patients meeting post-surgical cure criteria were included. Clinical and biochemical variables were analyzed preoperatively and at 3 and 12 months postoperatively to assess their relationship with persistent elevated PTH levels. Results: At 3 months post-surgery, 61.5% of patients had elevated PTH levels, while at 12 months, 54.8% still presented this alteration. It was found that patients with preoperative PTH levels above 84 pg/mL had a greater tendency to maintain elevated levels post-surgery (p=0.001). Additionally, higher preoperative 24-hour urinary calcium levels were associated with a greater probability of PTH normalization after surgery (p=0.007). Conclusion: In this study, 54.8% of patients who underwent surgery for primary hyperparathyroidism due to a single adenoma had persistently elevated PTH levels postoperatively. High preoperative PTH concentrations and hypercalciuria were relevant factors in post-surgical outcomes. Follow-up studies are needed to assess the long-term clinical implications of this condition.
