HLA and MuSK-positive myasthenia gravis: A systemic review and meta-analysis.

Objectives: Myasthenia gravis (MG) represents a spectrum of clinical subtypes with differences in disease mechanisms and treatment response. MG with muscle-specific tyrosine kinase (MuSK) antibodies accounts for 1%-10% of all MG patients. We conducted a meta-analysis to evaluate the association between HLA genes and MuSK-MG susceptibility.

Myasthenia gravis and infectious disease.

Background And Purpose: Myasthenia gravis (MG) is an autoimmune disease with muscular weakness as the only symptom, and often with immunosuppressive treatment. All these aspects could have relevance for the risk of infections as well as their prophylactic and curative treatment.

Methods: This is a review article, where Web of Science has been searched for relevant key words and key word combinations.

Pathophysiology and immunological profile of myasthenia gravis and its subgroups.

Myasthenia gravis (MG) is an autoimmune antibody-mediated disease characterized by muscle weakness and fatigability. It is believed that the initial steps triggering humoral immunity in MG take place inside thymic tissue and thymoma. The immune response against one or several epitopes expressed on thymic tissue cells spills over to neuromuscular junction components sharing the same epitope causing humoral autoimmunity and antibody production.

Multiple antibody detection in 'seronegative' myasthenia gravis patients.

Background And Purpose: Myasthenia gravis (MG) is an autoimmune disease caused by antibody mediated impairment in the neuromuscular junction. Seronegative MG (SNMG) without antibodies against acetylcholine receptor (AChR) and muscle-specific kinase (MuSK) by routine assays accounts for about 20% of all MG patients.

Methods: Plasma from 81 Chinese MG patients previously found to be seronegative was tested by routine assays for AChR and MuSK antibodies.
