Variable presentation and outcomes of primary hyperparathyroidism in children and adolescents.

Abstract

Primary hyperparathyroidism (PHPT) in paediatric and adolescent age group presents with some unique challenges for clinicians. While the disease in the adult counterparts presents with symptoms which are described quite extensively in literature, children/adolescents have manifestations which are quite different and severe compared to the former. The present case series aimed to highlight the peculiarities of presentation of PHPT in children and adolescents. In this case series, we present experience of 5 cases of PHPT in children and adolescents from our centre. We compared our data with the data already available in literature. We have also described salient presenting features of PHPT in individuals less than 19 years old previously reported in literature and pointed out the specificities of this disease at this age group. PHPT in children and adolescents should be considered as a separate entity compared to that in adults, given its unique features, such as rachitic features, and severity of different presenting phenotypes. Persistence of rachitic features despite vitamin D correction, pancreatitis, bilateral nephrolithiasis and otherwise unexplained psychiatric abnormalities of insidious onset require greater clinical vigilance and serum/urine calcium testing to rule out this uncommon yet possible entity.
