Health-related quality of life in parents and partners of people with type 1 diabetes: Development and validation of type 1 diabetes and life (T1DAL) measures.

Introduction: Despite the significant impact of type 1 diabetes (T1D) on family, few instruments are available to assess health-related quality of life (HRQOL) among family members of people with T1D. This study aimed to develop and evaluate the psychometric properties of new measures of diabetes-specific HRQOL for parents and partners of people with T1D. We report on the multistep development and validation process for the self-report Type 1 Diabetes and Life (T1DAL) measures, with versions for parents of youth age <8, 8-11, 12-17, and 18-25 years, and for partners of people age ≥18 years with T1D.

Design and psychometrics for new measures of health-related quality of life in adults with type 1 diabetes: Type 1 Diabetes and Life (T1DAL).

Aims: To use a three-phase process to develop and validate new self-report measures of diabetes-specific health-related quality of life (HRQOL) for adults with type 1 diabetes. We report on four versions of the Type 1 Diabetes and Life (T1DAL) measure for people age 18-25, 26-45, 46-60, and over 60 years.

Methods: We first conducted qualitative interviews to guide measure creation, then piloted the draft measures.

Assessing Health-Related Quality of Life in Children and Adolescents with Diabetes: Development and Psychometrics of the Type 1 Diabetes and Life (T1DAL) Measures.

Objective: To develop and validate new measures of diabetes-specific health-related quality of life (HRQOL) for people with type 1 diabetes (T1D) that are brief, developmentally appropriate, and usable in clinical research and care. Here we report on the phases of developing and validating the self-report Type 1 Diabetes and Life (T1DAL) measures for children (age 8-11) and adolescents (age 12-17).

Methods: Measure development included qualitative interviews with youth and parents (n = 16 dyads) followed by piloting draft measures and conducting cognitive debriefing with youth (n = 9) to refine the measures.

Improved medical-alert ID ownership and utilization in youth with congenital adrenal hyperplasia following a parent educational intervention.

Background: Classical congenital adrenal hyperplasia (CAH) is a potentially life-threatening condition, and adrenal crisis is a major cause of morbidity and mortality in affected children. Medical-alert identification (ID) could prevent complications of adrenal crisis by identifying the need for time-sensitive, critical treatment. Our objectives were to evaluate usage of medical-alert IDs by CAH youth, ownership and awareness of IDs amongst their parents, and the effect of an in-clinic educational intervention on ID utilization.

Alefacept provides sustained clinical and immunological effects in new-onset type 1 diabetes patients.

Background: Type 1 diabetes (T1D) results from destruction of pancreatic β cells by autoreactive effector T cells. We hypothesized that the immunomodulatory drug alefacept would result in targeted quantitative and qualitative changes in effector T cells and prolonged preservation of endogenous insulin secretion by the remaining β cells in patients with newly diagnosed T1D.

Methods: In a multicenter, randomized, double-blind, placebo-controlled trial, we compared alefacept (two 12-week courses of 15 mg/wk i.

Effects of vitamin D repletion on glycemic control and inflammatory cytokines in adolescents with type 1 diabetes.

Objective: Little is known about the relationship between vitamin D deficiency and adolescents with type 1 diabetes. On the basis of adult studies showing that vitamin D improves insulin sensitivity and decreases inflammatory cytokines linked to microvascular complications, we hypothesized that treating vitamin D deficiency in adolescents with type 1 diabetes would improve glycemia and reduce inflammatory markers.

Research Design And Methods: This was a randomized, prospective, crossover study of 25 adolescents with type 1 diabetes for at least a year (aged: 13-21 yr; 62% female; 62% Hispanic) and vitamin D deficiency (25-OH vitamin D ≤30 ng/mL).

Targeting of memory T cells with alefacept in new-onset type 1 diabetes (T1DAL study): 12 month results of a randomised, double-blind, placebo-controlled phase 2 trial.

Background: Type 1 diabetes results from autoimmune targeting of the pancreatic β cells, likely mediated by effector memory T (Tem) cells. CD2, a T cell surface protein highly expressed on Tem cells, is targeted by the fusion protein alefacept, depleting Tem cells and central memory T (Tcm) cells. We postulated that alefacept would arrest autoimmunity and preserve residual β cells in patients newly diagnosed with type 1 diabetes.

Costimulation modulation with abatacept in patients with recent-onset type 1 diabetes: follow-up 1 year after cessation of treatment.

OBJECTIVE We previously reported that 2 years of costimulation modulation with abatacept slowed decline of β-cell function in recent-onset type 1 diabetes (T1D). Subsequently, abatacept was discontinued and subjects were followed to determine whether there was persistence of effect. RESEARCH DESIGN AND METHODS Of 112 subjects (ages 6-36 years) with T1D, 77 received abatacept and 35 received placebo infusions intravenously for 27 infusions over 2 years.

Co-stimulation modulation with abatacept in patients with recent-onset type 1 diabetes: a randomised, double-blind, placebo-controlled trial.

Background: The immunopathogenesis of type 1 diabetes mellitus is associated with T-cell autoimmunity. To be fully active, immune T cells need a co-stimulatory signal in addition to the main antigen-driven signal. Abatacept modulates co-stimulation and prevents full T-cell activation.

Antigen-based therapy with glutamic acid decarboxylase (GAD) vaccine in patients with recent-onset type 1 diabetes: a randomised double-blind trial.

Background: Glutamic acid decarboxylase (GAD) is a major target of the autoimmune response that occurs in type 1 diabetes mellitus. In animal models of autoimmunity, treatment with a target antigen can modulate aggressive autoimmunity. We aimed to assess whether immunisation with GAD formulated with aluminum hydroxide (GAD-alum) would preserve insulin production in recent-onset type 1 diabetes.

Improvement in risk factors for metabolic syndrome and insulin resistance in overweight youth who are treated with lifestyle intervention.

Objective: To evaluate the prevalence of risk factors that are associated with the metabolic syndrome and insulin resistance in overweight youth and to determine the effect of a short-term, family-centered, lifestyle intervention on various associated anthropometric and metabolic measures.

Methods: Overweight youth who were between 8 and 16 years of age participated in a 12-week, family-centered, lifestyle intervention program. Anthropometric and metabolic measures were assessed before the program in all participants (n = 109) and after the program in a subset of the participants (n = 43).

Prader-Willi syndrome and mosaic Turner's syndrome.

We present a female with both Prader-Willi syndrome and Turner's syndrome, a combination not previously reported. We review her clinical presentation and discuss her growth pattern, mental development, and puberty, in relation to her mosaic Turner and Prader-Willi syndromes.

Rathke's cleft cyst in two girls with precocious puberty.

Rathke's cleft cysts arise from remnants of Rathke's pouch and are usually found incidentally on MRI or autopsy. In childhood, the most common presenting symptoms of Rathke's cleft cysts are endocrine abnormalities, such as reduced growth hormone secretion, hyperprolactinemia, or diabetes insipidus. Non-specific symptoms, such as headache and visual disturbance, may also occur.

Hypertension in hypophosphatemic rickets--role of secondary hyperparathyroidism.

Hypertension has been anecdotally reported in children with familial hypophosphatemic rickets (XLH). To better identify and characterize the clinical and laboratory features of hypertensive XLH children, we reviewed the medical records of 41 XLH children, all treated with phosphate and vitamin D analogues. Eight children, who were originally normotensive, developed hypertension during the 2nd decade of life.

IGFs and IGFBPs: role in health and disease.

The insulin-like growth factors (IGFs), IGF-binding proteins (IGFBPs), and IGFBP proteases are the main regulators of somatic growth and cellular proliferation. IGFs are involved in growth pre-natally and post-natally. Dysregulation of the IGF axis can lead to growth disorders such as growth hormone deficiency and acromegaly.
