Abstract

No standardised and universal treatment is available for antisynthetase syndrome. In particular, there is an unmet need for a single efficient treatment acting on its various manifestations, including interstitial lung disease, myositis and polyarthritis.We describe the cases of two patients with multiple and severe manifestations, including joint, muscular and lung involvement, both refractory to various treatments, including rituximab, who demonstrated significant improvement of all their manifestations, including joint, muscular and lung diseases on tocilizumab. The response was also long-lasting, with both patients still being in full remission after >10 years of treatment.Our experience shows that interleukin-6 inhibition could be a very effective treatment option in antisynthetase syndrome, with efficacy on a wide spectrum of manifestations.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
