The aim of this review was to summarize recent advances in the understanding of
the clinical and autoantibody phenotypes, their associated outcomes and the
pathogenesis of the juvenile idiopathic inflammatory myopathies (JIIMs). The
major clinical and autoantibody phenotypes in children have many features similar
to those in adults, and each has distinct demographic and clinical features and
associated outcomes. The most common myositis autoantibodies in JIIM patients are
anti-p155/140, anti-MJ and anti-MDA5. Higher mortality has been associated with
overlap myositis as well as with the presence of anti-synthetase and anti-MDA5
autoantibodies; a chronic illness course and lipodystrophy have been associated
with anti-p155/140 autoantibodies; and calcinosis has been associated with
anti-MJ autoantibodies. Histologic abnormalities of JIIMs detectable on muscle
biopsy have also been correlated with myositis-specific autoantibodies; for
example, patients with anti-MDA5 show low levels of inflammatory infiltrate and
muscle damage on biopsy. The first genome-wide association study of adult and
juvenile dermatomyositis revealed three novel genetic associations, BLK, PLCL1
and CCL21 and confirmed that the human leucocyte antigen region is the primary
risk region for juvenile dermatomyositis. Here, we review the well-established
pathogenic processes in JIIMs, including the type 1 interferon and endoplasmic
reticulum stress pathways. Several novel JIIM-associated inflammatory mediators,
such as the innate immune system proteins, myeloid-related peptide 8/14, galectin
9 and eotaxin, have emerged as promising biomarkers of disease. Advances in our
understanding of the phenotypes and pathophysiology of the JIIMs are leading to
better tools to help clinicians stratify and treat these heterogeneous disorders.
