“…11 Autoantibodies to seven other, less frequently targeted, aminoacyl tRNA synthetases have also been described in patients with polymyositis and interstitial lung disease (TABLE 1). 11,12 In addition, an autoantibody to a 48-kDa transfer RNA-related protein (Wa) has been described. 13 These non-Jo-1 antisynthetase antibodies are detected in only about 3% of myositis patients.…”

“…Raros relatos de casos sugerem um padrão de necrose difusa em biópsias musculares em pacientes com autoanticorpos Anti-ARS positivos (KASHIF et al, 2017;PRAYSON et al, 2017;MEHDIRATTA et al, 2012;MEYER et al, 2014). Portanto um padrão histopatológico bem definido para categorizar um paciente com SAS é de suma importância, pois a presença isolada de um autoanticorpo Anti-ARS pode ser um epifenômeno (ANCUTA et al, 2011) ou mesmo estar relacionado a uma MAS não SAS (ANDRADE et al, 2021). Definir os critérios de inclusão e exclusão desses pacientes é de extrema importância, a fim de atenuar o viés de seleção, aumentar a homogeneidade da amostra e enriquecer a literatura para novos estudos e futuras revisões da literatura.…”
