Auxological, Clinical, and MRI Abnormalities in Pediatric Patients With Isolated Growth Hormone Deficiency.

OBJECTIVE:  This study aimed to assess the auxological, clinical, and MRI features of pediatric patients with isolated growth hormone deficiency (GHD) by analyzing the demographic and clinical characteristics of the study cohort. METHODS: A cohort of 115 pediatric patients diagnosed with isolated GHD was included. The patients were evaluated at a tertiary center in Jeddah, Saudi Arabia. Collected data included demographic information and auxological evaluations, such as height standard deviation (SD), height centile, weight SD, weight centile, and bone age SD. Neuroradiological assessments, particularly magnetic resonance imaging (MRI) of the hypothalamic-pituitary region, were collected to identify any structural abnormalities contributing to GHD. RESULTS: A total of 67 (SD 58.3) were males. The mean age was 9.55 years (SD 3.45). The mean bone age was 7.37 years (SD 3.24), indicating delayed bone development. Height measurements reflected a significant growth impairment, with a mean height SD of -2.45 (SD 1.12). Out of the 115 pediatric patients in the study cohort, 84 (73%) underwent neuroradiological assessments using brain MRI. Among these, 12% were found to have MRI abnormalities. The prevalence of MRI abnormality in the subgroup with severe growth hormone deficiency was higher, reaching 21%. The peak growth hormone (GH) in the growth hormone stimulation test was 6.38 ng/mL (SD 3.24). There was a significant difference in the peak GH levels between the subgroup of patients with normal MRI findings (mean 6.02 ng/mL, SD 2.47) and those with abnormal MRI findings (mean 3.2 ng/mL, SD 2.8) (p=0.01). CONCLUSION: Children with isolated GHD exhibited significant growth impairment and clinical characteristics consistent with the disorder. Neuroradiological abnormalities are common among patients with severe growth hormone deficiency; therefore, radiological assessment including MRI of the pituitary gland is recommended in patients with severe isolated growth hormone deficiency.

Indices of insulin resistance and adiposity can detect obesity-related morbidity in pediatrics.

OBJECTIVES: To evaluated obesity-related morbidity prevalence among overweight/obese children and adolescents in Saudi Arabia, adiposity indicators and insulin resistance as obesity-related morbidity predictors. METHODS: We enrolled 318 overweight/obese children attending a Pediatric Endocrinology Clinic at King Abdulaziz University Hospital, Saudi Arabia, aged 2-20 years in this retrospective cross-sectional study from September 2019 to March 2021. All children had nutritional obesity, and their body mass index (BMI) standard deviation score was higher than one standard deviation score above the mean for their age and gender. Clinical adiposity indices including BMI, waist circumference (WC), waist-hip ratio (WHR), and bioimpedance analysis (BIA) of body composition were assessed. Biochemical testing of insulin resistance through homeostasis model assessment for insulin resistance and fasting insulin was performed, along with receiver operating curve analysis to obtain optimal cut-off points for obesity-related morbidity. RESULTS: Obesity related morbidity was found in 61.9%, whereas insulin resistance was detected among 64.7% of the patients. Body mass index standard deviation score, WC, BAI of body composition-derived body fat, homeostasis model assessment for insulin resistance, and fasting insulin are significant obesity-related morbidity predictors, and the cut-off points were established. CONCLUSION: Obesity-related morbidity is widely prevalent among obese children and insulin resistance is a key factor in its prediction. Clinical adiposity indices, given their accuracy and practicability, are important predictors of obesity-related morbidity.

The Impact of Diabetes Distress on the Glycemic Control Among Adolescents and Youth With Type 1 Diabetes in Two Tertiary Centers, Jeddah, Saudi Arabia.

Introduction Adolescents with type 1 diabetes (T1D) experience multiple symptoms of diabetes distress including fear of acute complications such as severe hypoglycemia which may lead to permanent brain damage or death. They also experience fear of acute hyperglycemia that can lead to diabetic ketoacidosis as well as chronic complication including diabetic nephropathy and retinopathy. No previous research was conducted in Saudi Arabia to assess diabetes distress among adolescents and youth with T1D. This study aimed to assess diabetes distress in adolescents and youth with T1D and its relation to clinical characteristics, glycemic control and diabetes co-morbidities. Methodology A cross-sectional study was conducted on 158 patients at King Abdulaziz University Hospital and Dr. Erfan and Bagedo General Hospital, Jeddah, Saudi Arabia. Data about participants' characters, episodes of DKA, last HbA1c level, diabetes co-morbidities were collected. Diabetes distress (DD) was assessed by the Problem Areas in Diabetes (PAID) and Diabetes Distress Scale (DDS) scores. Results The prevalence of diabetes distress among our population of adolescents with T1D was 24.1%. The mean scores of PAID and DDS were 43.56 ± 13.84 and 2.22 ± 1.05, respectively. Patients with suboptimal HbA1c had significantly higher mean PAID and DDS scores. There is also a significant positive correlation between HbA1c level and number of ketoacidosis episodes. A highly significant positive correlation was found between PAID and DDS scores. Conclusion This study found that participants with uncontrolled HbA1c had significantly higher mean PAID and DDS scores with a significant positive correlation between the last HbA1c measured level and number of ketoacidosis attacks and PAID and DDS scores. Future studies on larger samples are needed to implement interventions to minimize the burden of diabetes distress among adolescents with T1D.
