Anti-HMGCR myopathy: a first case report from North Africa and literature insights.
Review in Frontiers in immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) myopathy is a rare idiopathic inflammatory myopathy characterized by severe muscle damage and minimal extra-muscular involvement. This report presents the first documented case of severe, treatment-resistant HMGCR-myopathy in a Tunisian and North African patient. A 43-year-old man with no significant medical history experienced progressive muscle weakness over one year, leading to difficulty walking. Examination revealed pronounced proximal muscle weakness, particularly in the lower limbs, with significant quadriceps atrophy. Laboratory results indicated elevated Creatine Kinase (CK) levels at 10000 UI/l and Lactate dehydrogenase (LDH) at 400 UI/l. Electromyography confirmed myogenic damage, and muscle biopsy revealed extensive muscle necrosis and regeneration with moderate inflammatory infiltrates. Screening for anti-HMGCR antibodies was positive. Initial treatment with high-dose prednisone showed a good response but led to flares upon tapering. Subsequent treatment with methotrexate, azathioprine, and rituximab resulted in partial clinical and biological improvement. This case underscores the challenges in diagnosing and managing anti-HMGCR myopathy due to limited awareness and access to testing.
