Background: The hallmark of congenital hyperinsulinism (CHI) is the demonstration of detectable plasma insulin during hypoglycaemia. Insulin can be undetectable in a significant proportion of patients with CHI. Plasma samples for insulin requires rapid and careful handling for reliable results. There is little published data on the value of C-peptide in the diagnosis of CHI.Objective and hypotheses: To assess the usefulness of C-peptide in the diagnosis ...

Introduction: Autoimmune thyroid diseases are multifactorial diseases with a genetic susceptibility and environmental factors. A potential role of the Fas apoptotic inhibitory molecule 2 (FAIM2) gene, the high-affinity alpha subunit (CD25) of the interleukin-2 receptor (IL-2RA) gene, the cytotoxic T cell antigen 4 (CTLA-4) gene polymorphisms on autoimmune thyroid diseases (AITDs) in children has not been established equivocally yet.Objective: To estimate...

Background: C-peptide secretion is the most accurate measurement of residual β-cell function in type 1 diabetes (T1D) and even residual levels seem to positively correlate with a lower probability of complications.Objective and hypotheses: Identify key determinants to the evolution of the β pancreatic cell function, measured by fasting C-peptide (FCP).Method: Prospective study of patients diagnosed with T1D, with evaluati...

Background: Some IGFALS variants have been reported in more than one ALS-deficient family raising the question whether they originated from a single common ancestor allele (founder effect) or alternatively, as independent mutational events (hot spot). Since c.103dupG (p.E35Gfs*17) is located in a stretch of five consecutive guanine residues, where both G-duplication and deletion have been described in several families, we speculate that this region could be a hot spot...

Introduction: Since the 1980s, long-acting gonadotropin-releasing hormone analogues (GnRHa) have been the standard treatment for central precocious puberty (CPP).Aims: To evaluate the short-term response (at 6 and 12 months) of treatment with GnRHa in female children diagnosed with CPP, regarding growth, bone maturation (Greulich and Pyle method), predicted adult height (PAH) and pubertal development (Tanner stages)....

Background and aims: A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted attention as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus (T2DM). MOTS-c profiles have not yet been reported in human obesity and T2DM. We aimed to determine circulating MOTS-c levels in obesity and explore the association between MOTS-c levels and various metabolic parameters. Methods: In this case-control study, 40 obese chil...

Background and Aims: A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted interests as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus in mice. MOTS-c profiles have not yet been reported in type 1 diabetes (T1DM). We aimed to determine circulating MOTS-c levels in T1DM and explore the association between MOTS-c levels and various metabolic parameters.Metho...

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...

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...

Background: Type 1 pseudohypoaldosteronism (PHA1) is a rare syndrome characterized by unresponsiveness to aldosterone. Diagnosis is established by high levels of aldosterone and plasma renin activity, associated with findings of hypoaldosteronism (hyponatremia, hyperkalemia and metabolic acidosis). When the inheritance pattern is autosomal recessive it expresses as a severe systemic disease and the mortality rate is high, especially in the neonatal period....
