Background and Aims: Insulin pump therapy may o"er superior glycemic control compared to multiple daily injections (MDI) in specific populations. Closed-loop insulin delivery systems show promise but have limited data in the Saudi pediatric and young adult populations. This study aimed to evaluate the e#cacy of insulin pump therapy in children with type 1 diabetes previously treated with multiple daily injections.Methods:</s...

Background: Pancreatic agenesis has been reported as a cause of neonatal diabetes. Most commonly it was associated with severe neurodevelopmental problems caused by homozygous mutations in the transcription factor PTF1A. Isolated pancreatic agenesis was related to biallelic mutations in an enhancer located near PTF1A gene, which suggests that the enhancer is tissue specific to the pancreas. PDX1 is another transcription factor gene in which biallelic mutation ...

Introduction:• Adrenal insufficiency is a rare, but potentially fatal medical condition 1.• In children, the cause is most commonly congenital adrenal hyperplasia (CAH) but in recent years a growing number of causative gene mutations have been identified resulting in syndromes that share primary adrenal insufficiency (PAI) characteristics.<p cl...

Background: Congenital hypothyroidism (CH) characterized by a deficient secretion of thyroid hormone in newborn. It is the most common endocrine disease in the children with an incidence rate about 1: 3000 live births in Saudi Arabia. Thyroid dysgenesis and dyshormonogenesis are the most common causes. Thyroid dyshormonogensis commonly inherited as autosomal recessive disorders. Although Thyroglobulin followed by TSHR mutations are the most common genetic defe...

Background: Hereditary Vitamin D-Resistant Rickets (HVDRR) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) resulting in end organ resistant to 1a,25-dihydroxyvitamin D, [1,25(OH)2D]. Majority of HVDRR has Elevated 1, 25(OH)2D which is a hallmark for diagnosis of this disease. High doses of vitamin D, oral calcium and most importantly IV calcium infusion are the mode of therapy in HVDRR.A...

Background: Vitamin-D deficiency becomes a worldwide issue, and major cause of rickets in younger age groups. Multiple causes lead to vitamin-D deficiency in which nutritional causes contribute the major factor. The synthesis of bioactive vitamin-D requires hydroxylation at 1α and 25 positions by cytochrome-P450 in the kidney and liver, respectively. Recently, human CYP2R1 has been reported as a major factor for 25-hydroxylation, in which it contributes for the inherited ...

Background: Neonatal severe primary hyperparathyroidism (NSHPT, MIM 23900) is a potentially lethal autosomal recessive disorder characterized by severe hypercalcemia, markedly elevated serum PTH levels and skeletal abnormalities that include multiple fractures, demineralization and erosions. It is secondary to biallelic loss of function mutation in the CASR gene that encodes the calcium sensing receptor.Case presentation: We identified a 10-day old baby ...

Background: X-chromosome monosomy is the most common sex abnormality in females, with a higher prevalence of cancer than the general population. Virilizing adrenocortical tumors are rarely seen in patients with Turner’s Syndrome. There have been 2 reported cases of simultaneous TP53 mutations (Li Fraumeni’s syndrome) and Turner’s syndrome. Here we report first case with this rare association from Kuwait.Clinical...

Background: Most children with short stature (SS) remain without a clear diagnosis despite extensive workup and are thus classified as idiopathic short stature (ISS). Whole exome sequencing (WES) in particular, has become a revolutionary approach in identifying monogenic causes of growth disorders. Therefore, this study aims to determine the diagnostic yield of WES in identifying the genetic etiology in children with ISS.Methods:...

Background: Traditionally patients with X-linked Hypophosphatemic Rickets (XLH) have been treated with conventional therapy, however, in 2018, the FDA approved Burosumab use in XLH patients.Objective: To investigate Burosumab effectiveness on pediatric patients with XLH by observing an improvement in serum phosphorus concentration and total rickets severity score (RSS) within 12 months period.<stro...
