PG - e616-e621 LID - 10.1097/RHU.0000000000001418 [doi] AB - INTRODUCTION: Inflammatory myopathies are treated with glucocorticoids and other immunosuppressive medications. Intravenous immunoglobulin (IVIG) is increasingly used for refractory or severe cases; however, the evidence for their effectiveness is limited. We assessed effectiveness and safety of IVIG when used with other immunomodulatory agents in the treatment of inflammatory myopathies. METHODS: This study reviewed records of patients diagnosed with dermatomyositis or polymyositis and treated with IVIG, from 2009 through 2016 in 1 tertiary medical center. Mixed-effects general linear regression models were applied to determine effectiveness of treatment on muscle strength, creatinine phosphokinase levels, and steroid dosage. RESULTS: Twenty-three patients with dermatomyositis/polymyositis treated with IVIG were followed up for a mean of 31 (SD, +/-25) months. During this period, a significant improvement in muscle strength was demonstrated, with a mean increase of 0.92 Medical Research Council scale points (beta = 0.14; confidence interval [CI], 0.136-0.149; p < 0.0001), a significant reduction of creatinine phosphokinase levels and steroid dosage with a mean decrease of 1140 IU/L (beta = -0.274; CI, -0.354 to -0.195; p < 0.0001), and 36 mg/d (beta = -0.008; CI, -0.011 to -0.006; p < 0.0001), respectively. Overall, remission was observed in 10 patients (43.5%), and partial remission in 6 patients (26%), whereas 1 patient (17%) remained refractory to treatment, and 6 patients (27%) were lost to follow-up. CONCLUSIONS: The majority of patients with inflammatory myopathies experienced a clinical and laboratory improvement during IVIG treatment. In addition, a steroid-sparing effect was noticed in most patients. These results encourage the use of IVIG as an alternative treatment option for patients with limited responsiveness to conventional methods. CI - Copyright (c) 2020 Wolters Kluwer Health, Inc.
