Abstract

Background: The presence of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies in dermatomyositis (DM) is associated with an increased risk of developing rapidly progressive interstitial lung disease (RP-ILD) and a poor prognosis.

Objectives: We aimed to explore whether tofacitinib could improve the prognosis of Anti-MDA5 antibody positive DM-interstitial lung disease (ILD).

Design: Systematic review and meta-analysis.

Data Sources And Methods: Studies were included if they compared mortality rate and infection events in patients with anti-MDA5 antibody positive DM-associated ILD who were treated with or without tofacitinib.

Results: The systematic review and meta-analysis included a total of 148 patients from four cohort studies. Fifty-eight patients with anti-MDA5 antibody positive DM-ILD who received combined treatment-containing tofacitinib were enrolled in the experimental group. Additionally, 90 DM-ILD patients who did not receive tofacitinib-based therapy were included in the control group. The pooled risk ratio (RR) for all-cause mortality was 0.61 (95% CI, 0.41-0.91,  = 0.02) with  = 0 indicating no heterogeneity among the included studies. For virus infection risk, the pooled RR was 1.92 (95% CI, 0.90-4.10,  = 0.09), while bacterial and fungal infection-associated RRs were found to be 1.29 (95% CI, 0.65-2.55,  = 0.47) and 1.15 (95% CI, 0.46-2.89,  = 0.77), respectively. There was no statistically significant difference in infection risk between the two groups, and no heterogeneity was observed.

Conclusion: Our findings suggest that tofacitinib may reduce the risk of all-cause mortality in patients with anti-MDA5 antibody-positive DM-ILD without an increased risk of additional infections.
