Partial Clinical Remission Of Type 1 Diabetes Mellitus In Children: Clinical Applications And Challenges With Its Definitions, Benjamin U. Nwosu Mar 2019

Partial Clinical Remission Of Type 1 Diabetes Mellitus In Children: Clinical Applications And Challenges With Its Definitions, Benjamin U. Nwosu

Benjamin U. Nwosu

The honeymoon phase, or partial clinical remission (PCR) phase, of Type 1 diabetes mellitus (T1DM) is a transitory period that is marked by endogenous insulin production by surviving β cells following a diabetes diagnosis and the introduction of insulin therapy. It is a critical window in the course of the disease that has short and long-term implications for the patient, such as a significant reduction in the risk of long-term complications of T1DM. To promote long-term cardiovascular health in children with newly diagnosed T1DM, three key steps are necessary: the generation of a predictive model for non-remission, the adoption of …

Inclusion criteria: GHST using arginine and clonidine. Exclusion criteria: hypopituitarism, abnormal pituitary magnetic resonance imaging scan, syndromic obesity, or syndromic short stature. Data were expressed as mean ± SD. Results: The over-weight/obese children with peak GH of <10 μg/L had significantly lower value for natural log (ln) peak GH (1.45 ± 0.09 vs. 1.83 ± 0.35, p = 0.022), but similar values for GV SDS, insulin-like growth factor-I, insulin-like growth factor binding protein-3, bone age, BA − CA, MPTH, and child height SDS minus MPTH SDS compared to normal-weight peers with GHD. After adjusting for covariates, the over-weight/obese children (BMI ≥ 85th percentile) were >7 times more likely than normal-weight subjects (BMI < 85th percentile) to have a peak GH of <10 μg/L, and 23 times more likely to have a peak GH of <7 μg/L (OR = 23.3, p = 0.021). There was a significant inverse …

Benjamin U. Nwosu

Background: The associations of 25-hydroxyvitamin D [25(OH)D], non-high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL), and related markers of early cardiovascular disease (CVD) are unclear in prepubertal children.

Objective: To investigate the association of 25(OH)D with markers of CVD. The hypothesis was that 25(OH)D would vary inversely with non-HDL-C.

Subjects and methods: A prospective cross-sectional study of children (n=45; 26 males, 19 females) of mean age 8.3 ± 2.5 years to investigate the relationships between 25(OH)D and glucose, insulin, high-sensitivity C-reactive protein, and lipids. Vitamin D deficiency was defined as 25(OH)D/mL; overweight as body mass index (BMI) ≥ 85 th but …

The Relationship Between Adiposity And Stature In Prepubertal Children With Celiac Disease, Benjamin U. Nwosu, Rachel I. Snook, Louise S. Maranda

Benjamin U. Nwosu

Background and Aim: The pathogenesis of short stature in celiac disease (CD) is unknown. Obese children are generally taller than their non-obese peers; however, the role of adiposity on stature in CD is unclear. Our aim was to determine the association between adiposity and stature in CD.

Subjects and methods: We compared the anthropometric characteristics of prepubertal children of ages 3-12 years, with biopsy-proven CD (n=40) and who were not on gluten-free diet, to same aged, prepubertal non-CD children (n=50). Body mass index (BMI) was calculated using the formula weight/height2. Sex-adjusted midparental target height (MPTH) standard deviation score (SDS) was …

Double Diabetes: The Evolving Treatment Paradigm In Children And Adolescents, Benjamin U. Nwosu

Benjamin U. Nwosu

The global pandemic of obesity in children and adolescents has resulted in a new expression of diabetes mellitus designated as double diabetes. The entity encompasses the autoimmune load of Type 1 Diabetes and the metabolic load of Type 2 Diabetes. There is no consensus on the best therapeutic modality for this new expression of diabetes mellitus. Optimal therapeutic options must address the coexistence of both metabolic and autoimmune components of diabetes mellitus in the patient. There have also been calls to revise the current classification of diabetes mellitus to take into account the surging prevalence of double diabetes in children …

Serum 25-Hydroxyvitamin D Levels Do Not Correlate With Asthma Severity In A Case-Controlled Study Of Children And Adolescents, Jennifer Menon, Louise Maranda, Benjamin U. Nwosu

Benjamin U. Nwosu

Background: There is no consensus on the association between vitamin D and asthma.

Objective: To determine the relationship between 25-hydroxyvitamin D [25(OH)D] levels and asthma symptom severity in children and adolescents.

Methods: A retrospective, case-control study of 263 subjects of ages 2–19 years with asthma who were compared to 284 non-asthmatic controls of similar ages. Subjects were excluded if they had diseases of calcium or vitamin D metabolism or were receiving calcium or vitamin D supplementation. Serum 25(OH)D was measured in all subjects. Asthma symptom severity, usually stratified into 6 steps, was stratified into five steps [1–5] based on the …
