Actualización en el tratamiento del hipoparatiroidismo posquirúrgico / Update on management of postoperative hypoparathyroidism

Introducción y objetivo: El hipoparatiroidismo posquirúrgico es una complicación frecuente de la cirugía tiroidea y paratiroidea, con consecuencias significativas sobre la salud y calidad de vida. El objetivo de esta revisión es proporcionar una visión actualizada de su prevención, detección precoz y tratamiento.Síntesis: Tras la tiroidectomía y paratiroidectomía puede aparecer hipoparatiroidismo de forma aguda, especialmente en algunos pacientes de alto riesgo. La determinación de la hormona paratiroidea intacta (PTHi) en el postoperatorio temprano es una herramienta útil en el manejo del paciente. Un nivel de PTHi postoperatoria <10-15 pg/ml, combinado con los niveles de calcemia 24 horas después de la cirugía, ofrece el mejor valor predictivo para hipocalcemia aguda. El hipoparatiroidismo permanente se asocia con morbilidad y deterioro de calidad de vida a largo plazo y debería prevenirse cuando sea posible. El tratamiento convencional incluye calcio oral y metabolitos activos de vitamina D. En caso de hipocalcemia severa o sintomática se precisa calcio intravenoso. El tratamiento debe monitorizarse e incluir educación sanitaria del paciente, para evitar amplias desviaciones de la calcemia. Sin embargo, con la terapia convencional mantener un adecuado control puede representar un desafío. (AU)

Introduction and objective: Surgical hypoparathyroidism is a common complication following thyroid and parathyroid surgery. It has significant consequences for health and quality of life. The objective of this review is to provide an overview of its prevention, early detection, and treatment. Synthesis: Acute hypoparathyroidism can occur after thyroidectomy and parathyroidectomy, especially in high-risk patients. Measurement of early postoperative intact parathyroid hormone (PTHi) can help guide patient management. A postoperative PTHi < 10-15 pg/ml combined with serum calcium assay testing 24 hours after surgery yielded the highest diagnostic accuracy for predicting acute hypocalcemia. Permanent hypoparathyroidism is associated with long-term morbidity and poor quality of life, and should be prevented whenever possible. Conventional treatment consist of oral calcium and active vitamin D analogs. For more severe or symptomatic hypocalcemia it is necessary intravenous calcium. Treatment require monitoring and patient education to avoid wide swings in serum calcium. However, with standard therapy, maintaining an adequate control often presents a therapeutic challenge. Recombinant human parathyroid hormone (rhPTH) replacement can lower the doses of calcium and active vitamin D analogs required, while maintaining serum calcium and phosphate levels within the recommended therapeutic ranges. It may improve bone metabo-lism and quality of life on the long term. Additional data on safety and efficacy are needed. Conclusions: Postoperative hypoparathyroidism is common. It requires early diagnosis, pharmacologic intervention and patient education to achieve optimal control and lower the risk of long-term complications. rhPTH seems to be an effective option for those patients who do not stably mantein their calcium in the target range.

Effect of the type of specialized nutrition support on the course of the patient with amyotrophic lateral sclerosis (ALS). Interhospital registry SCLEDyN.

INTRODUCTION: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease in which specialized nutritional support is essential. The objectives of our study were to describe nutritional support at the beginning of follow-up and its impact on anthropometry and survival. METHODS: An interhospital registry was created for the hospitals of Castilla-León through a web platform designed for this purpose. An anamnesis was carried out on the evolution and nutritional history of the disease; and classical anthropometry was determined. The prescribed nutritional treatment was recorded. The parameters were measured at the beginning, at six and twelve months of nutritional follow-up. RESULTS: A total of 93 patients [49 (52.7%) spinal; 44 (47.3%) bulbar)] were analyzed. The nutritional support route at the beginning was oral diet in 36 (38.7%) patients; oral nutritional supplementation (SON) in 46 (49.5%) patients; and in 11 (11.8%) patients percutaneous endoscopic gastrostomy (PEG). A decrease in the body mass index (BMI) was observed between the first and second visit [Start: 24.18 (3.29) kg/m2; 6 months: 23.69 (4.12) kg/m2; P < .05]. Less weight loss was observed at 6 months compared to the start of nutritional follow-up [Start: 8.09 (8.72)%; 6 months: 1.4 (6.29)%; P < .01]. 36 (38.7%) patients died but with no differences according to when nutritional support was started. Survival from the onset of symptoms was higher in the group of patients with artificial nutrition, although without reaching statistical significance [Oral: 28 (20.25) months; SON: 30 (16.75-48.25) months; PEG: 39 (27-52) months; P = .90]. CONCLUSIONS: Patients with ALS present a severe deterioration in nutritional status before the start of nutritional support. After the nutritional intervention, a slowdown in weight loss and nutritional deterioration was observed.
