The ability of superantigens to activate large numbers of T cells suggests that they may play a role in the course of autoimmune disorders. Data from several animal models of autoimmune disorders including experimental allergic encephalomyelitis and collagen induced arthritis supports this hypothesis. Administration of bacterial superantigens can induce an exacerbation of the autoimmune process...

multiple sclerosis (ms) is a complex, demyelinating disease of the central nervous system (cns) with variable phenotypic presentations, while guillain-barre syndrome (gbs) is the prototypic acute inflammatory disorder that affects the peripheral nervous system. myasthenia gravis (mg) is a t cell dependent and antibody mediated autoimmune disease. although it has been shown that complement plays...

Autoimmune neutropenia (AIN), resulting from granulocyte-specific autoantibodies, is much less frequent than other autoimmune hematologic disorders including autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP). These autoimmune disorders may precede, synchronize, or follow collagen disorders, viral infections, and lymphoid neoplasms. Herein we present the first case of AIN in a...

OBJECTIVE Autoimmune hepatitis and primary sclerosing cholangitis are chronic inflammatory disorders of unknown aetiology, frequently associated with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCAs) directed against an unknown antigen of myeloid cells. METHODS AND RESULTS Here, it is reported that p-ANCAs in autoimmune liver disorders react with beta-tubulin isotype...

High cortisol level in endogenous Cushing’s syndrome suppresses the immune system and after treatment there may be an over activity of immune reaction leading to autoimmune diseases mostly thyroid and rheumatologic disorders. This is the second reported case of multiple sclerosis developing after treatment of Cushing’s syndrome. A 42-year old man is reported who presented with bone fracture and...
