Background: Classic congenital adrenal hyperplasia, primarily due to 21-hydroxylase deficiency, leads to impaired cortisol and aldosterone production and excess adrenal androgens. Lifelong glucocorticoid therapy is required, often necessitating supraphysiological doses in youth to manage androgen excess and growth acceleration. These patients experience higher obesity rates, hypertension, and glucose metabolism issues, complicating long-term health management.

Objective: The reason for center differences in metabolic control of childhood diabetes is still unknown. We sought to determine to what extent the targets, expectations, and goals that diabetes care professionals have for their patients is a determinant of center differences in metabolic outcomes.

Research Design And Methods: Children, under the age of 11 with type 1 diabetes and their parents treated at the study centers participated.

Article Synopsis
  • This study investigates the effects of antithymocyte globulin (ATG) in preserving beta cell function in new-onset type 1 diabetes over a two-year period.
  • A randomized, double-blind trial involved 58 participants, with a treatment of 6.5 mg/kg ATG or placebo, focusing on safety and immunological responses.
  • Results showed that while overall endpoints were not met, older patients receiving ATG exhibited better C-peptide levels compared to those on placebo, but both groups experienced a high number of adverse events.

Background: Type 1 diabetes results from T-cell-mediated destruction of β cells. Findings from preclinical studies and pilot clinical trials suggest that antithymocyte globulin (ATG) might be effective for reducing this autoimmune response. We assessed the safety and efficacy of rabbit ATG in preserving islet function in participants with recent-onset type 1 diabetes, and report here our 12-month results.

Unlabelled: Growth hormone 1 (GH1) gene deletions occur in approximately 10-15% of patients with severe isolated, GH deficiency (GHD). The standard treatment for GHD is GH replacement. Individuals with GH gene defects, however, may form GH antibodies that interfere with the efficacy of exogenous recombinant GH (rhGH) therapy.

The differential diagnosis of vomiting and dehydration in the first month of life includes congenital adrenal hyperplasia (CAH) and pyloric stenosis (PS). Each diagnosis may mask the presence of the other, requiring careful evaluation and follow-up. We document the occurrence of CAH and PS in two Hispanic siblings.

Continuous subcutaneous insulin infusion (CSII) was first introduced as a mode of treatment for persons with type 1 diabetes mellitus (T1DM) in the late 1970s. Since that time, there have been many reports and reviews of this modality of treatment in adults and adolescents with diabetes and several reports of the use of this technology in the treatment of children with T1DM. Conflicting data have accumulated on the consistency of improvement in hemoglobin A1c (HbA1c) and in the frequency of complications, most significantly that of hypoglycemia.
