Increased Risk For Vitamin D Deficiency In Obese Children With Both Celiac Disease And Type 1 Diabetes, Nithya Setty-Shah, Louise S. Maranda, Benjamin U. Nwosu Dec 2014

Increased Risk For Vitamin D Deficiency In Obese Children With Both Celiac Disease And Type 1 Diabetes, Nithya Setty-Shah, Louise S. Maranda, Benjamin U. Nwosu

Benjamin U. Nwosu

Background. It is unknown whether the coexistence of type 1 diabetes (T1D) and celiac disease (CD) increases the risk for vitamin D deficiency.

Aims. To determine the vitamin D status and the risk for vitamin D deficiency in prepubertal children with both T1D and CD compared to controls, TID, and CD.

Subjects and Methods. Characteristics of 62 prepubertal children of age 2–13 y with either CD + T1D (� = 22, 9.9 ± 3.1 y), CD only (� = 18, 8.9 ± 3.3 y), or T1D only (� = 22, 10.1 ± 2.8 y) were compared to 49 controls of …


Hepatic Dysfunction Is Associated With Vitamin D Deficiency And Poor Glycemic Control In Diabetes Mellitus, Benjamin Nwosu, Zheni Stavre, Louise Maranda, Karen Cullen, Mary Lee Sep 2014

Hepatic Dysfunction Is Associated With Vitamin D Deficiency And Poor Glycemic Control In Diabetes Mellitus, Benjamin Nwosu, Zheni Stavre, Louise Maranda, Karen Cullen, Mary Lee

Mary M. Lee

Background/Aims: The effect of the rising prevalence of nonalcoholic fatty liver disease on the 25-hydroxylation of pre-vitamin D in the liver, and consequent glycemic control in children with diabetes mellitus is not known. Our aim was to determine whether mild hepatic dysfunction was associated with impaired 25-hydroxylation of pre-vitamin D, and if this vitamin D deficiency was associated with impaired glycemic control in children and adolescents with type 1 diabetes (TIDM) and type 2 diabetes (T2DM).

Methods: We analyzed simultaneously measured HbA1c, ALT, AST, and 25OHD levels and clinical parameters in 121 children and adolescents with T1DM (n=81) and T2DM …


Data From: The Effects Of Vitamin D Supplementation On Hepatic Dysfunction, Vitamin D Status, And Glycemic Control In Children And Adolescents With Vitamin D Deficiency And Either Type 1 Or Type 2 Diabetes Mellitus, Benjamin U. Nwosu, Louise S. Maranda Jun 2014

Data From: The Effects Of Vitamin D Supplementation On Hepatic Dysfunction, Vitamin D Status, And Glycemic Control In Children And Adolescents With Vitamin D Deficiency And Either Type 1 Or Type 2 Diabetes Mellitus, Benjamin U. Nwosu, Louise S. Maranda

Benjamin U. Nwosu

Background: The effects of vitamin D supplementation on mild hepatic dysfunction and glycemic control are unclear in children and adolescents with either type 1 (T1D) or type 2 diabetes (T2D). Hypothesis: Vitamin D supplementation will improve hepatic dysfunction and glycemic control. Aim: To determine the effect of vitamin D supplementation on alanine transaminase (ALT), hemoglobin A1c (HbA1c), and serum 25-hydroxyvitamin D [25(OH)D] concentration. Subjects and Methods: A retrospective study of 131 subjects with either T1D (n=88: 46 females, 42 males), or T2D ( n=43: 26 females, 17 males) of ages 3-18 years between 2007-2013. All subjects had (1) a diagnosis …

Is Vitamin D Deficiency A Feature Of Pediatric Celiac Disease?, Jeffrey Villanueva, Louise Maranda, Benjamin U. Nwosu Jun 2012

Is Vitamin D Deficiency A Feature Of Pediatric Celiac Disease?, Jeffrey Villanueva, Louise Maranda, Benjamin U. Nwosu

Benjamin U. Nwosu

Background: Celiac disease (CD) is an autoimmune enteropathy characterized by villus atrophy and malabsorption of essential nutrients. Vitamin D deficiency has been described in autoimmune diseases, but its status in prepubertal children with CD has not been adequately studied.

Objective: To determine the vitamin D status of prepubertal children with CD.

Study design: A retrospective study of prepubertal children aged 3–12 years with CD (n=24) who were compared to prepubertal, non-CD children of the same age (n=50). Children were included in the study if they had a diagnosis of CD by intestinal biopsy, and were not on a gluten-free diet …


Does Hepatic Dysfunction Worsen Glucose Homeostasis By Impairing Vitamin D Metabolism?, Benjamin U. Nwosu Apr 2012

Does Hepatic Dysfunction Worsen Glucose Homeostasis By Impairing Vitamin D Metabolism?, Benjamin U. Nwosu

Benjamin U. Nwosu

The Management of diabetes mellitus (DM) remains an enigma even though the symptoms of the disease had been described more than 3000 years ago. This is because the central therapeutic goal of DM therapy, euglycemia, is influenced by complex physiologic and pathologic processes, some of which are clearly understood, while others are less clear. Suboptimal glycemic control is a recognized risk factor for acute and chronic complications of diabetes including microvascular and macrovascular diseases. The central question for this editorial is whether mild hepatic dysfunction could impair vitamin D metabolism and secondarily lead to sub-optimal glycemic control.
