AbstractPituitary stalk interruption syndrome (PSIS) is a rare disease associated with either isolated growth hormone deficiency (GHD) or combined pituitary hormone deficiency (CPHD). In older children and adults, most patients experience short stature or hypogonadism. Neonatal PSIS is extremely rare and is difficult to recognize due to absence of dwarfism. However, when this condition occurs in newborns, it is often life-threatening. Here, we collected patients with neonatal PSIS to clarify its characteristics to improve its early diagnosis.The patients included in this study were treated at the pediatric endocrine department of Shandong Provincial Hospital from January 2017 to July 2020. We obtained the clinical characteristics, endocrine hormone levels, pituitary magnetic resonance imaging (MRI) and further genetic data for all the patients. Hormone therapy was first given at the time of diagnosis, and the patients received regular follow-up.Three neonatal patients were identified in our clinic. The characteristics of these patients included hypoglycemia and jaundice, as well as CPHD, which included features such as micropenis and hypothyroidism. Genetic etiology was still hard to discover. All the patients responded well to alternative therapy, and the longest follow-up period was 3 years. Regular replacement ensures good prognosis.Sustained hypoglycemia and jaundice in newborns, indicate the presentation of PSIS. Early recognition is of great importance to avoid a life-threatening crisis.Copyright © 2021 the Author(s). Published by Wolters Kluwer Health, Inc.
