background : type 1 diabetes mellitus (t1dm) is an autoimmune disease characterized by selective destruction of pancreatic beta cells.   methods: the study included 80 children, 20 of them have t1dm, 40 children were selected from first degree relatives to the same child and 20 healthy children serve as control. body mass index (bmi) was calculated, random blood glucose and glycosylated hemoglo...

In this study, the characterization of insulin (auto)antibodies has been described, mainly in terms of concentration (q), affinity (Ka) and Ig (sub)isotypes by Surface Plasmon Resonance (SPR) in two particular clinical cases of individuals with severe episodes of impaired glycemia. Subject 1 suffers from brittle diabetes associated with circulating insulin antibodies (IA) due to insulin treatme...

OBJECTIVE Immune intervention trials in recent-onset type 1 diabetes would benefit from biomarkers associated with good therapeutic response. In the previously reported randomized placebo-controlled anti-CD3 study (otelixizumab; GlaxoSmithKline), we tested the hypothesis that specific diabetes autoantibodies might serve this purpose. RESEARCH DESIGN AND METHODS In the included patients (n = 4...

BACKGROUND Insulin autoantibodies (IAA), antibodies against endogenous insulin, may be detected in type 1 diabetic children before the start of insulin treatment. OBJECTIVE To relate IAA to islet antibodies (i.e., islet cell antibodies [ICA], and antibodies against two ICA-related islet antigens, glutamic acid decarboxylase 65 [GADA] and protein tyrosine phosphatase IA-2 [IA-2 A]) at diagnosi...

To clarify whether glutamic acid decarboxylase65 antibodies (GAD65 Ab) and insulin autoantibodies (IAA) are good predictive markers for insulin-dependency in NIDDM, we studied GAD65 Ab and IAA in NIDDM patients treated with diet alone or in combination with oral hypoglycemic agents. GAD65 Ab were found in 12 of 229 (5.2%, P=0.079 vs. control) NIDDM patients and IAA in 8 of 229 (3.5%). The frequ...

INTRODUCTION The aim of this study was to evaluate beta-cell function and insulin resistance in relation to the occurrence of anti-islet antibodies in first degree relatives of patients with type 1 diabetes (T1D). MATERIAL AND METHODS The group studied consisted of 90 relatives and 60 healthy individuals without a family history of diabetes. An intravenous glucose tolerance test (IVGTT) was p...

The objective was to evaluate the prevalence and association of several markers (islet cell antibodies: ICA, insulin autoantibodies: IAA, glutamic acid decarboxylase antibodies: GADA and ICA512 antibodies: ICA512A) along with HLA DQB1 genotype in type 1 diabetes mellitus of recent onset, including siblings and individuals without any history of this disease, in an Argentine population. A total ...

Background: Type 1 Diabetes mellitus (T1DM) results from a cellular-mediated autoimmune destruction of the β-cells of the pancreas. We designed this study to determine the prevalence of autoantibodies among Saudis patients with T1DM. Methods: Glutamic acid decarboxylase antibodies (GADA), antibodies to Islet cell (ICA) and Insulin (IAA) were measured in 171 Saudis patients with T1DM. Results: T...

Family history of type 1 diabetes and autoantibodies to the islet antigens insulin (IAA), glutamate decarboxylase (GADA), and the protein tyrosine phosphatase-like protein IA-2 (IA-2A) are strong predictors of type 1 diabetes, but the rate of progression to diabetes in multiple islet autoantibody-positive relatives varies widely. We asked whether detailed characterization of islet autoantibodie...
