Implementation of type 1 diabetes genetic risk screening in children in diverse communities: the Virginia PrIMeD project.

Background: Population screening for risk of type 1 diabetes (T1D) has been proposed to identify those with islet autoimmunity (presence of islet autoantibodies). As islet autoantibodies can be transient, screening with a genetic risk score has been proposed as an entry into autoantibody testing.

Methods: Children were recruited from eight general pediatric and specialty clinics across Virginia with diverse community settings.

Precision Medicine in Type 1 Diabetes.

Type 1 diabetes is a complex, chronic disease in which the insulin-producing beta cells in the pancreas are sufficiently altered or impaired to result in requirement of exogenous insulin for survival. The development of type 1 diabetes is thought to be an autoimmune process, in which an environmental (unknown) trigger initiates a T cell-mediated immune response in genetically susceptible individuals. The presence of islet autoantibodies in the blood are signs of type 1 diabetes development, and risk of progressing to clinical type 1 diabetes is correlated with the presence of multiple islet autoantibodies.

No central adrenal insufficiency found in patients with Prader-Willi syndrome with an overnight metyrapone test.

Background Individuals with Prader-Willi syndrome (PWS) have hypothalamic dysfunction and may have central adrenal insufficiency (CAI). The prevalence of CAI in PWS remains unknown. Methods Twenty-one subjects with PWS aged 4-53 years underwent a low dose adrenocorticotropic hormone (ACTH) stimulation test (LDAST) (1 μg/m2, maximum 1 μg) followed by an overnight metyrapone test (OMT).

Medication-induced diabetes mellitus.

Epidemiological studies and case reports have demonstrated an increased rate of development of diabetes mellitus consequent to taking diverse types of medication. This review explores this evidence linking these medications and development of diabetes and presents postulated mechanisms by which the medications might cause diabetes. Some medications are associated with a reduction in insulin production, some with reduction in insulin sensitivity, and some appear to be associated with both reduction in insulin production and insulin sensitivity.
