An Irish Regional Study of Paediatric Growth Hormone Deficiency (CO-GHD): Classification of Causes and Factors Associated with Persistent GHD at Transition

Grace Mariana , Joyce Caroline , Morissey Rose , Moore Michael , O'Connell Susan

Childhood-onset growth hormone deficiency (CO-GHD) is topical at present due to the increasing understanding of underlying genetic aetiologies, influence on childhood growth, and future effects on adolescence and adult health. There is no previous Irish data of this group of children.Methods: A retrospective cohort study over 2 years (2013-2015) including all children diagnosed with GHD who received recombinant growth hormone treatment (rGH). Predictors ...

Compound Heterozygosity for Two Novel POU1F1 Mutations in Siblings with Isolated Childhood Onset Growth Hormone Deficiency (CO-GHD)

Grace Mariana , Nagel Mato , Joyce Caroline , Morissey Rose , O'Connell Susan

Background: CO-GHD can be caused by a variety of aetiologies, including pituitary or brain structural abnormalities, and increasingly recognised genetic mutations of pituitary transcription factors. Idiopathic GHD is a diagnosis of exclusion. POU1FI is a late pituitary transcription factor. Mutations of POU1F1 have autosomal recessive (AR) inheritance, and phenotypically present with a normal or small anterior pituitary gland on magnetic resonance imaging (MRI), they are assoc...

Primary Polydipsia in a Family with Mutation in the AVP Gene and Proven Central Diabetes Insipidus

Casey Ruth , Hannon Anne Marie , Joyce Caroline , O'Halloran Domhnall , O'Connell Susan

Background: Diabetes insipidus (DI) is characterised clinically by the inappropriate production of large volumes of dilute urine even in the presence of clinical dehydration or deprivation of water. DI occurs either due to a deficiency or insufficiency of arginine vasopressin (AVP) hormone production. Hereditary DI accounts for <10% of the DI cases. As hyponatraemic seizures secondary to inappropriate use of desmopressin can occur, caution is required before a diagnosis of...
