The impact of age, body mass index, and pubertal stage on C-peptide at type 1 diabetes diagnosis

Ayça Cimbek Emine , Ercüment Beyhun Nazım , Karagüzel Gülay

Background: Assessment of beta-cell function in type 1 diabetes (T1D) has important implications in both clinical and research settings. Studies are limited by the lack of adjustments demonstrating the extent to which puberty influences C-peptide levels. The aim of this study was to evaluate the influence of pubertal stage as well as age and body mass index (BMI) on multiple C-peptide measures at T1D diagnosis.Methods: T...

Residual C-peptide secretion and glycemic control in pediatric patients with Diabetes Mellitus type 1

João Gaia Maria , Pedrosa Inês , Adriana Rangel Maria , Arménia Campos Rosa , Luísa Leite Ana

Introduction: Residual C-peptide secretion has been associated with less hypoglycemic events and lower glycemic variability in patients with Diabetes Mellitus type 1 (DM1), primarily in adults. The authors sought to evaluate the association between residual C-peptide secretion in pediatric patients with DM1 and glycemic control variables.Methods: Cross-sectional study conducted in a level II hospital, in DM1 patients you...

Introduction: Non-communicable diseases are recognized as a major cause of morbidity in low and middle-income countries (LMICs). There are 21 francophone countries (>100 million speak French) in Sub-Saharan Africa (FSSA). We identified only 19 pediatric endocrinologists in FSSA (37% in Cameroon and Senegal) mostly trained in France or through the successful anglophone “Paediatric Endocrine Training Centers for (West) Africa” (PETC[W]A) offered i...

Objective: Hysterosalpingography (HSG) to assess patency of the Fallopian tubes with the use of iodinated (oil- or water-based) contrast media is a standard test during fertility work-up. An observational study found an increased risk of congenital hypothyroidism in neonates whose mothers were exposed to high amounts of oil-based contrast during HSG. Oil-based contrast contains more iodine (480mg Iodine/ml) than water-based contrast (250mg Iodine/ml). We inves...

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Background: C-peptide, an indicator of own insulin production, is usually very low in patients with type 1 diabetes (T1D).Objective and hypotheses: The aim of the study was to evaluate C-peptide levels in children and adolescents and young adults with T1D and to correlate them with glycemic control.Method: Fasting C-peptide levels were measured with RIA, in 118 children, adolescents and young adults (60 females, mean age 13.3 <smal...

Factors Affecting the Preservation of C-Peptide Secretion in Egyptian Children with Type 1 Diabetes

El-hawary Amany , Aboelenin Hadil , El-Helaly Rania , El-Gwad Ahmed Abd

Background: type I diabetes is associated with progressive destruction of pancreatic β-cells with gradual decline of insulin secretion. C-peptide is considered the best indicator of endogenous insulin secretion in patients with diabetes.Aim of the Work: evaluate the effect of different variables associated with preserved pancreatic beta cell function at one year after diagnosis of children with type I DM.<p c...

A Novel Human CYP19A1 Deletion-Insertion Mutation Reveals that the C-terminus of the Aromatase Protein is Crucial for its Activity

Ladjouze Asmahane , Sauter Kay-Sarah , Ouarezki Yasmine , Kedji Leila , Laraba Abdenour , Pandey Amit V , Fluck Christa E

Background: The steroidogenic enzyme aromatase is encoded by the CYP19A1 gene. Aromatase activity is required for estrogen biosynthesis from androgen precursors in the ovary and several extragonadal tissues. The role of aromatase and thus estrogens for human biology is best illustrated by disease states, both deficiency and excess which might be caused by genetic disorders.Aim: A novel deletion-insertion mutation spanning from intron 10 to the 3...

Introduction: To achieve glycemic control goals in patients with type 1 diabetes (T1D), they are instructed in three fundamental principles: diet, insulin therapy and physical activity. Physical activity recommendations for children and adolescents with T1D are the same as for the general population. Following the physical activity recommendations helps mitigate the increased cardiovascular risk inherent to DM. We set out to explore the degree of glycemic cont...
