Myopathy associated with anti-HMGCR antibodies showed mild limb weakness and favorable response to immunotherapy. All 8 patients exhibited increased signal intensities on short T1 inversion

Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin such as

Centronuclear (CNM) and X-linked Myotubular Myopathies (XLMTM) are rare genetic disorders (also known as orphan diseases ). GNE myopathy is a very rare genetic condition that causes muscles in the arms and legs to become increasingly weak. It is also known by several other names This is a list of some of the most commonly encountered disorders.

Objective. A pathogenic role of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies has been proposed. Our objective was to assess efficacy of rituximab (RTX) in anti-HMGCR immune-mediated necrotizing myopathy. Methods. All patients who had been treated with RTX were retrospectively reviewed to assess features and outcome.
