Poor Glycemic Control Is Associated With Impaired Bone Accrual in the Year Following a Diagnosis of Type 1 Diabetes.

Context: Type 1 diabetes (T1D) is associated with an increased fracture risk across the life course. The effects on bone accrual early in the disease are unknown.

Objective: To characterize changes in bone density and structure over the year following diagnosis of T1D and to identify contributors to impaired bone accrual.

Effects of genetic severity on glucose homeostasis in Friedreich ataxia.

Introduction: Friedreich ataxia (FRDA) leads to increased risk of diabetes. Less is known regarding the dynamics of glucose homeostasis in FRDA, the influence of disease features, and the utility of oral-based metrics for capturing metabolic dysfunction.

Methods: To examine these dynamics, we analyzed oral and intravenous glucose tolerance test data in 42 non-diabetic patients with FRDA.

A0001 in Friedreich ataxia: biochemical characterization and effects in a clinical trial.

This study tested the ability of A0001 (α-tocopheryl quinone; EPI-A0001), a potent antioxidant, to improve in vitro measures, glucose metabolism, and neurological function in Friedreich ataxia. We used an in vitro study of protection from cell toxicity followed by a double-blind, randomized, placebo-controlled trial of 2 doses of A0001 in 31 adults with Friedreich ataxia. The primary clinical trial outcome was the Disposition Index, a measure of diabetic tendency, from a frequently sampled intravenous glucose tolerance test, evaluated 4 weeks into therapy.
