Extrahepatic immunological manifestations of hepatitis C virus (HCV) are well described. In addition, antiglutamic acid decarboxylase (GAD) antibody-associated cerebellar ataxia is well-established entity. However, there have been no reports in the literature of anti-GAD antibody-associated ataxia as an extrahepatic manifestation of HCV infection. We report the case of a young woman with chroni...

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...

The cause of downbeat nystagmus (DBN) remains undiagnosed in about 40% of patients. This paper reports the presence of antiglutamic acid decarboxylase antibodies (GAD-Ab) in a patient with DBN. Antibodies against GABAergic neurons located in the vestibular complex may induce chemical denervation of the floccular neurons, which normally suppress the peripheral imbalance between vertical semicirc...

Answer: B A 45-year-old man developed recurrent partial seizures with secondary generalisation. Four years earlier, he had fi rst presented with diplopia from left abducens palsy and right hemiparesthesia, followed by left hemiparesis 1 month later. His magnetic resonance imaging (MRI) brain scan done then is shown in Figure 1. His MRI cervical spine with contrast was unremarkable for any cord ...

We examined the histological changes of the pancreas in a 75-year-old diabetic woman who was treated with sulphonylurea for 10 years and required insulin treatment for the subsequant 10 years. She was positive for antiglutamic acid decarboxylase antibody (GAD Ab) 20 years after the diagnosis of diabetes. Her autopsied pancreas revealed disfigured islets and no beta cells. These changes were ind...

Recognizing stiff person syndrome is clinically important. It is uncommon, characterized by body stiffness associated with painful muscle spasms, and varies in location and severity. It is subdivided into stiff trunk versus stiff limb presentation, and as a progressive encephalomyelitis. Stiff person-type syndrome also reflects a paraneoplastic picture. Most patients demonstrate exaggerated lum...

antibodies directed against the enzyme glutamic acid decarboxylase (gad) are believed to be the main cause of destruction of pancreatic islet cells in type i (insulin dependent) diabetes mellitus. the enzyme was found both in the brain and pancreatic beta cells. although similarities in identity of gad in human and rat brain have been demonstrated, little is known about the interaction between ...

PURPOSE This study investigated the prevalence of islet autoantibodies in children and adults with T1DM according to their age and the duration of disease. METHODS We measured the levels of islet autoantibodies, including antiglutamic acid decarboxylase antibody (anti-GAD Ab), and combined these with anthropometric measurements and laboratory tests of 137 patients newly diagnosed with T1DM du...

Background: a metabolic condition characterized by failure in the metabolism of proteins, lipids, and carbohydrates that is brought on problems with insulin production. When multiple autoantibodies, such as those against glutamic acid decarboxylase, are present different antigens, type 1 diabetes present. Objective: To estimate Glutamic Acid Decarboxylase Autoantibodies assessment HbA1c DM. Met...
