HMGCR antibodies-associated NAM is recognized myopathic disease with challenging therapeutic strategies. Patients with this disorder require aggressive immunosuppressive treatment. Some case series explored various immunosuppressive agents, with NAM symptoms generally being less receptive to immunotherapy than the inflammatory myopathies.

This is a phase 2, pilot, randomized, placebo-controlled trial of Gamunex-C IVIG as mono-therapy for HMGCoA reductase auto-antibody positive (HMGCR) necrotizing myopathy. The trial will test the feasibility and initial efficacy of Gamunex-C IVIG mono-therapy in HMGCR necrotizing myopathy. 2016-10-01 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 red yeast rice, which is statin rich. The pathophysiology of anti-HMGCR IMNM has a clear autoimmune basis and requires long-term immunosuppressive therapy and differs from statin-induced myopathy which typically resolves on withdrawal of the statin [ 9 ].
Muscle biopsy remains the gold standard for diagnosis. These disorders are potentially treatable with proper diagnosis and initiation of therapy. Goals of treatment Oct 22, 2020 X-linked myotubular myopathy, otherwise known as XLMTM, is a rare genetic disorder that primarily causes muscle weakness. The protein Jun 2, 2020 In this condition, the heart muscle becomes abnormally thick, which makes it harder for the heart to pump blood. Learn the causes and av P Mohassel · 2019 · Citerat av 19 — After confirmation of anti-HMGCR myopathy, all patients (n = 6) were treated with IV immunoglobulins (IVIg) and seen in follow-up at the NIH. Steroids (methylprednisolone, 750 mg every 3 weeks) were added to P6's regimen after 4 months of IVIg therapy. av N Chrestian · 2020 — P.297 A case of juvenile HMGCR antibody myositis presenting as limb HMGCR antibody myositis with great improvement on IVIG treatment.

In contrast, anti-HMGCR myopathy is often associated with statin exposure and intravenous immunoglobulin treatment may be an effective treatment, even as monotherapy. Both anti-SRP and anti-HMGCR myopathy tend to be most severe in younger patients. The general consensus is that best treatment involves withdrawing the statin and giving immunosuppressive and immunomodulatory treatment.
anti-HMGCR myopathy in older patients, some individuals develop this condition without a known statin exposure2,3. To date, effective treatment strategies have not been estab-lished in clinical trials. Nonetheless, many patients with anti-HMGCR myopathy improve with immunosuppressive therapy, and current expert opinion guidelines recommend

Our objective was to assess efficacy of rituximab (RTX) in anti-HMGCR immune-mediated necrotizing myopathy. While corticosteroid-free treatment of anti-HMGCR myopathy is now a safe option in selected cases, initial triple steroid/IVIG/SSI was very efficacious in induction. Delays in treatment initiation and, as a corollary, delays in achieving remission decrease the odds of achieving successful maintenance with an SSI alone.

After the discovery of anti-HMGCR autoantibodies, several international groups identified and characterized more patients, expanding the phenotypic spectrum of this disease to include pediatric patients and young adults without statin … Objective: A pathogenic role of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies has been proposed.
