Evaluation of copeptin in children after stimulation with clonidine or L-Dopa.
Objectives: Arginine-stimulated serum copeptin has been proposed as a new method to diagnose arginine vasopressin (AVP) deficiency in children and adolescents. Herein we investigated the secretagogic potential of clonidine or L-Dopa on the copeptin serum levels in children.
Methods: Eight stimulation tests (4 with clonidine and 4 with L-Dopa) were performed in eight children (5 boys and 3 girls) with a median age of 6.5 years-old, evaluated for short stature due to possible growth hormone deficiency. Serum copeptin levels were measured at 30, 60, 90, and 120 min after administration of clonidine or L-Dopa.
Results: Copeptin levels in serum did not show any significant change in either test (clonidine or L-Dopa). The values of copeptin levels compared to the baseline value did not deviate more than 5 % in the clonidine arm (p=0.60) or 8 % in the L-Dopa arm (p=0.75) respectively.
Conclusions: Data do not support the use of L-Dopa or clonidine as stimulants for evaluating AVP relating disorders in clinical pediatric practice.
期刊介绍：
The aim of the Journal of Pediatric Endocrinology and Metabolism (JPEM) is to diffuse speedily new medical information by publishing clinical investigations in pediatric endocrinology and basic research from all over the world. JPEM is the only international journal dedicated exclusively to endocrinology in the neonatal, pediatric and adolescent age groups. JPEM is a high-quality journal dedicated to pediatric endocrinology in its broadest sense, which is needed at this time of rapid expansion of the field of endocrinology. JPEM publishes Reviews, Original Research, Case Reports, Short Communications and Letters to the Editor (including comments on published papers),. JPEM publishes supplements of proceedings and abstracts of pediatric endocrinology and diabetes society meetings.
