Key result
No viral RNA, bacterial DNA, or increased antibody titers to putative infectious agents were detected in children with active juvenile dermatomyositis or controls.
Why the study?
Are enteroviral RNA or bacterial DNA detectable in MRI-directed muscle biopsies from children with active untreated juvenile dermatomyositis?
Case-Control
Are enteroviral RNA or bacterial DNA detectable in MRI-directed muscle biopsies from children with active untreated juvenile dermatomyositis?
The study found no evidence of enteroviral RNA or bacterial DNA in muscle biopsies of children with active juvenile dermatomyositis, suggesting other triggers or mechanisms.
No takes yet. Share an insight, caveat, or question.
No evidence of these pathogens in JDM biopsies does not support infectious workup; leaves open non-microbial triggers for prospective study.
Pachman et al. (1995) conducted a case-control in Juvenile dermatomyositis. Putative infectious agents vs. Age-matched children with neurologic disease was evaluated on Presence of increased titers of circulating antibody to putative infectious agents and detectable viral RNA or bacterial DNA. No viral RNA, bacterial DNA, or increased antibody titers to putative infectious agents were detected in children with active juvenile dermatomyositis or controls.
