Pubertad precoz y pubertad rápidamente progresiva durante el confinamiento por la pandemia por COVID-19 / Rapidly progressive precocious puberty during the COVID-19 lockdown

RESUMEN

Introducción. Durante la pandemia por COVID-19, observamos un aumento de consultas por pubertad precoz (PP). Nuestro objetivo fue determinar la frecuencia de PP y su progresión antes y durante la pandemia. Métodos. Estudio retrospectivo, observacional y analítico. Se evaluaron las historias clínicas de los pacientes que consultaron en Endocrinología Infantil entre abril de 2018 y marzo de 2021. Se analizaron las consultas por sospecha de PP durante la pandemia (período 3) y se compararon con 2 años previos (períodos 1 y 2). Se recolectaron datos clínicos y estudios complementarios de la evaluación inicial y su progresión. Resultados. Se analizaron 5151 consultas. Se observó un aumento de consultas por sospecha de PP durante el período 3 (21 % vs.10 % y 11 %, p <0,001). Los pacientes que consultaron por sospecha de PP durante el período 3 aumentaron 2,3 veces (80 vs. 29 y 31, p <0,001). El 95 % fueron niñas; esa población fue analizada. Se incluyeron 132 pacientes que fueron similares en edad, peso, talla, edad ósea y determinaciones hormonales en los 3 períodos. En el período 3, se observó un menor índice de masa corporal, mayor porcentaje de estadio mamario Tanner 3-4 y mayor longitud uterina. Se indicó tratamiento al diagnóstico en el 26 % de los casos. En el resto, se controló su evolución. Durante el seguimiento, se observó una evolución rápidamente progresiva con mayor frecuencia durante el período 3 (47 % vs. 8 % vs. 13 %; p 0,02). Conclusiones. Evidenciamos un aumento de la PP y una evolución rápidamente progresiva en niñas durante la pandemia.

ABSTRACT

Introduction. During the COVID-19 pandemic, an increase in consultations for precocious puberty (PP) was observed. Our objective was to determine the frequency of PP and its progression before and during the pandemic. Methods. Retrospective, observational, analytical study. The medical records of patients who consulted with the Department of Pediatric Endocrinology between April 2018 and March 2021 were assessed. Consultations for suspected PP during the pandemic (period 3) were analyzed and compared to the 2 previous years (periods 1 and 2). Clinical data and ancillary tests done in the initial assessment and PP progression information were collected. Results. Data from 5151 consultations were analyzed. An increase in consultations for suspected PP was observed during period 3 (21% versus 10% and 11%, p < 0.001). Patients who consulted for suspected PP during period 3 increased 2.3-fold (80 versus 29 and 31, p < 0.001). In total, 95% were female; this was the population analyzed. We included 132 patients with similar age, weight, height, bone age, and hormonal characteristics in the 3 periods. During period 3, a lower body mass index, a higher percentage of Tanner breast stage 3­4, and a greater uterine length were observed. Treatment was indicated upon diagnosis in 26% of the cases. In the rest, their evolution was monitored. During follow-up, a rapidly progressive course was observed more frequently in period 3 (47% versus 8% versus 13%, p 0.02). Conclusions. We observed an increase in PP and a rapidly progressive evolution in girls during the pandemic.
