Antibodies directed against the 65-kd isoform of GAD (GAD65) are seen in a variety of autoimmune neurologic disorders including stiff-man (Moersch-Woltman) syndrome, autoimmune cerebellitis, brain stem encephalitis, seizure disorders, neuromyelitis optica and other myelopathies, myasthenia gravis, Lambert-Eaton syndrome, and dysautonomia. GAD65 antibody is also the major pancreatic islet antibody and an important serological marker of predisposition to type 1 diabetes. Chloroquine and zambia When plaquenil doesn t work Decoration ideas for posters about chloroquine for school Hydroxychloroquine sulfate 200 mg dosage We report the case of a 42-year-old woman who presented with vertigo and migraine and rapidly developed cognitive decline and seizures. Both serum and cerebro-spinal fluid samples showed high titer of anti-glutamic acid decarboxylase anti-GAD65 antibodies 998,881 IU/ml and 54,687 IU/ml respectively. Glutamic acid decarboxylase GAD is present in highest concentration in brain and pancreatic beta cells. Antibodies specific for the 65 kDa isoform of glutamic acid decarboxylase GAD65 comprise the majority of pancreatic islet cell autoantibodies. They appear years before the onset of clinical diabetes. Objective Antibodies against glutamic acid decarboxylase 65 anti-GAD65 are associated with a number of neurologic syndromes. However, their pathogenic role is controversial. Our objective was to describe clinical and paraclinical characteristics of anti-GAD65 patients and analyze their response to immunotherapy. Methods Retrospectively, we studied patients n = 56 with positive anti-GAD65. GAD65 antibodies are found in the serum of approximately 8% of healthy subjects older than age 50, usually in low titer, but often accompanied by related "thyrogastric" autoantibodies. GAD65 autoantibody also serves as a marker of predisposition to other autoimmune disease that occur with type 1 diabetes, including thyroid disease (eg, thyrotoxicosis, Grave disease, Hashimoto thyroiditis, hypothyroidism), pernicious anemia, premature ovarian failure, Addison disease, (idiopathic adrenocortical failure) and vitiligo.

Treating a GAD65 antibody-associated limbic encephalitis with basiliximab a case study. Background Antibodies ABs against the 65-kDa isoform of the intracellular enzyme glutamate decarboxylase GAD65 have been found in limbic encephalitis LE and other neurological conditions. Unlike other immune-mediated epilepsies, antiglutamic acid decarboxylase 65 GAD65 antibody-mediated epilepsy is often poorly responsive to antiepileptic drugs AEDs and only moderately responsive to immune therapy with steroids, intravenous immunoglobulin IVIG, or plasma exchange PLEX. Jul 13, 2018 GAD-epilepsy patients can also develop diabetes or other neurological GAD65 antibody associated syndromes although this was not observed in our patients. Even in non-diabetic patients, the GAD65 antibody positivity is strongly associated with thyroid disease which was also present in 50% of our patients. Patient 1 had low titer antibodies against the VGKC complex but tested negative for Caspr2 and LGI1.
