Immune-mediated Necrotizing Myopathy With Increased Creatine Phosphokinase and Positive Signal Recognition Particle: A Case Report
Background: Knowledge about Immune-Mediated Necrotizing Myopathy (IMNM) has received significantly attention in recent years. In this study, we report a rare case of IMNM with increased Creatine Phosphokinase (CPK) and positive Signal Recognition Particle (SRP). Clinical Presentation and Intervention: The case was a 67-year-old male patient referred to Firozgar hospital affiliated to the Iran ...
متن کاملImmune-Mediated Necrotizing Myopathy, Associated With Antibodies to Signal Recognition Particle, Together With Lupus Nephritis: Case Presentation and Management
A male patient with limb weakness, myalgia and edema was subsequently found to have an immune-mediated necrotizing myopathy (IMNM) on biopsy. Targeted myopathic antibody analysis revealed antibodies to signal recognition particle (SRP). Anti-SRP-associated necrotizing myopathy was diagnosed. This case was complicated by the concurrent development of class III lupus nephritis. We discuss an inte...
متن کاملStatin-Induced Necrotizing Autoimmune Myopathy
A 76-year-old man with a history of two prior strokes complicated by residual mild cognitive impairment, atrial fibrillation, coronary artery disease, diabetes mellitus type 2, congestive heart failure, dyslipidemia, and stage 3 chronic kidney disease was admitted for failure to thrive and functional decline. Two months prior, he had been briefly hospitalized for fatigue and inability to walk. ...
متن کاملAscending paresis as presentation of an unusual association between necrotizing autoimmune myopathy and systemic lupus erythematosus.
A 45 year-old man went to the emergency room due to disease duration of 15 days of insidious onset and progressive course. It began with symmetrical weakness and pain in feet and ankles that extends upward to the knees. Later, this progressed to paraparesis with Creatine phosphokinase levels of 44,270 U/L and respiratory failure that required mechanical ventilation. Electromyography and muscle ...
متن کاملIdentifying statin-associated autoimmune necrotizing myopathy.
Statins up-regulate expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), the rate-limiting enzyme in cholesterol synthesis and the major target of autoantibodies in statin-associated immune-mediated necrotizing myopathy. As muscle cells regenerate, they express high levels of HMGCR, which may sustain the immune response even after statin therapy is stopped. Awareness of this e...
