ABSTRACT
El hipoparatiroidismo postquirúrgico se caracteriza por hipocalcemia, hiperfosfatemia, e hipercalciuria, secundarios a concentraciones bajas de la hormona paratiroidea. La prevalencia en Estados Unidos es 23-37 casos/100.000 años-persona. Tras la cirugía de cuello ocurre como complicación en 78% de los casos; 75% resuelve espontáneamente en los primeros 6 meses y en el 25% restante es permanente. El tratamiento requiere administrar calcio oral y análogos de vitamina D (calcitriol y alfacalcidol) de forma crónica; en casos complicados se puede emplear calcio intravenoso en el postquirúrgico inmediato y mediato; algunos pacientes no responden a la terapia estándar. Objetivo: describir las características clínicas y la respuesta al tratamiento médico en pacientes con hipoparatiroidismo postquirúrgico permanente. Material y métodos: estudio descriptivo, transversal, con componente analítico mediante revisión de expedientes clínicos de pacientes que asistieron a la consulta externa del Servicio de Endocrinología del Centro Médico Nacional 20 de Noviembre; universo 88 expedientes, muestra por conveniencia 55 expedientes. Resultados: 35(63.6%) pacientes alcanzaron control óptimo de tratamiento a dosis de calcio elemental de 5.7-9.79g/24h (p= 0.0001 chi cuadrado), mostrando calcio sérico promedio 8.36ï± 0.55 mg/dl y calcitriol con mediana de 0.5µg/24 h. 15(27.2%) pacientes presentaron efectos secundarios al uso de calcio oral, 3 de ellos requirieron manejo con Hormona Paratiroidea Recombinante Humana para alcanzar control óptimo. Conclusión: el calcio elemental por vía oral continúa siendo la piedra angular en el tratamiento del hipoparatiroidismo post quirúrgico permanente, con pocos efectos adversos. Se recomiendan más estudios aleatorizados para identificar las características de los pacientes candidatos al manejo con Hormona Paratiroidea Recombinante Humana...(AU)

BACKGROUND AND OBJECTIVE: The current guidelines on hypoparathyroidism offer a model for treating patients but do not cover real-world situations or patient diversity. Given the lack of data regarding hypoparathyroidism, a Delphi panel was convened in Spain to establish consensus in defining the characteristics of patients with chronic hypoparathyroidism not adequately controlled with conventional treatment, as well as to investigate patterns of management. MATERIAL AND METHODS: A presentation matrix provided a framework for characterizing inadequately controlled chronic hypoparathyroidism, based on four predefined patient groups: group 1 (normal biochemical levels and the patient feeling well); group 2 (abnormal biochemical levels and the patient feeling well); group 3 (normal biochemical levels and the patient feeling unwell); and group 4 (abnormal biochemical levels and the patient feeling unwell). Based on Likert scales (scored 1-9), the experts were asked to state their agreement/disagreement with the characteristics of patients with chronic hypoparathyroidism, including demographic data, family history, comorbidities, biochemical values, symptoms and quality of life. Consensus was achieved when ≥66% of the respondents were in agreement. RESULTS: Consensus was achieved on the importance of assessing demographic data and comorbidities (e.g., renal complications) in groups 2, 3 and 4; family medical history in groups 2 and 3; biochemical parameters (e.g., calcemia/urinary calcium excretion) in groups 2 and 4; and clinical symptoms and quality of life in groups 3 and 4. Consensus was also reached regarding the maintenance of several biochemical parameters and the need for personalized treatment and training in symptoms and complications. CONCLUSIONS: The Spanish expert panel reached consensus defining key disease parameters and factors of importance for characterizing and treating patients with inadequately controlled chronic hypoparathyroidism.
