Immunopathological features of myopathy associated with small-to-medium-sized vessel vasculitis and differences from autoimmune myositis
CONCLUSIONS: Patients with vasculitis demonstrated mild myofiber damage based on the lower involvement of CD56/NCAM-expressing myofibers compared to those with AIM. Complement component deposits on the vessel walls and hypervascularity in the endomysium areas may be immunopathological features of vasculitic myopathy.PMID:37706291 | DOI:10.55563/clinexprheumatol/hpoapl

Pyomyositis Secondary to Localized Cellulitis in a Dermatomyositis Patient: A Case Report and Review of Infectious Complications in Dermatomyositis
Clin Cosmet Investig Dermatol. 2023 Aug 11;16:2201-2209. doi: 10.2147/CCID.S417772. eCollection 2023.ABSTRACTDermatomyositis (DM) is an autoimmune disorder characterized by proximal muscle weakness and distinct cutaneous features. Unfortunately, infection is a frequent and potentially life-threatening complication in patients with DM. Here, we present a case of pyomyositis in a patient with DM resulting from localized cellulitis. The patient also presented with subcutaneous calcification nodules and dermatomyositis-associated lipodermatosclerosis nodules. To our knowledge, there have been no reports of pyomyositis in patie...

Differences in muscle magnetic resonance imaging findings between anti-signal recognition particle antibody-positive myopathy and anti-aminoacyl-tRNA synthetase antibody-positive myositis
CONCLUSIONS: A comparison of thigh MRI between anti-SRP myopathy and anti-ARS myositis showed different findings and lesion sites reflecting the different pathophysiology that may contribute to their diagnosis.PMID:37497714 | DOI:10.55563/clinexprheumatol/fjfkfs
