Successful treatment with tofacitinib for anti-melanoma differentiation-associated gene 5 antibody-positive juvenile dermatomyositis: case reports and review of the literature. Immunol Med 2024; 47:110-117. [PMID: 38557269 DOI: 10.1080/25785826.2024.2336687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 03/26/2024] [Indexed: 04/04/2024] Open
Abstract
Although the clinical efficacy of tofacitinib has been reported in adult patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive (Ab+) dermatomyositis, data on its use in refractory juvenile dermatomyositis (JDM) are scarce. We describe two female Japanese patients with anti-MDA5 Ab + JDM and rapidly progressive interstitial lung disease who achieved remission by adding tofacitinib to existing immunosuppressive drugs and present a literature review. While both patients received various immunosuppressive or anti-inflammatory treatments for induction therapy, remission could not be achieved. Subsequently, tofacitinib was administered to reduce the Krebs von den Lungen-6 level 5 months after diagnosis in one patient; the other patient received tofacitinib 4 months after diagnosis to reduce ferritin levels and skin manifestations. Subsequently, both patients achieved remission, and prednisolone was withdrawn. Tofacitinib reduced the interferon signature associated with dermatomyositis/JDM disease progression and exerted a therapeutic effect on dermatomyositis/JDM. We found six published cases from five articles of tofacitinib for refractory anti-MDA5 Ab + JDM. Except for one case of herpes simplex meningitis, the other cases, including ours, had improved disease activity without severe adverse events, and steroids and immunosuppressive medicines could be tapered. Tofacitinib could be considered an available therapy for refractory anti-MDA5 Ab + JDM.

Abstract
INTRODUCTION Connective tissue diseases (CTDs) are a category of conditions that affect tissues that support and provide structure to the body. These diseases include rheumatoid arthritis, systemic lupus erythematosus, dermatomyositis, and sclerosing diseases. CTDs can be caused by dysregulation of inflammatory pathways, specifically an upregulation of interferons and JAK/STAT pathway activation. AREAS COVERED While CTDs have historically been treated with broadly immunosuppressant medications such as corticosteroids and disease-modifying antirheumatic drugs (DMARDS), newer and more targeted immunomodulating medications called Janus kinase inhibitors (JAKi), have emerged as potential treatments. EXPERT OPINION While most studies regarding JAKi for CTDs have focused on adult populations, pediatric patients with CTDs may also benefit from JAKi therapy. Moreover, the JAK/STAT inhibitor tofacitinib has been approved by the FDA for the treatment of active polyarticular course juvenile idiopathic arthritis. In this review, we have summarized what has been published on the use of JAKi for various pediatric CTDs.

High-Emergency Lung Transplantation for Interstitial Lung Disease Associated With Anti-MDA5 Dermatomyositis: A Case Report. Transplant Proc 2021; 53:2613-2615. [PMID: 34511249 DOI: 10.1016/j.transproceed.2021.08.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 08/07/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Rapidly progressive interstitial lung disease (RPILD) associated with the anti-melanoma differentiation-associated gene 5 antibody-positive (anti-MDA5ab+) dermatomyositis (DM) is a rare but life-threatening condition despite immunosuppressive treatment. We report the case of a 44-year-old woman who was diagnosed with severe RPILD associated with anti-MDA5ab+ DM 1 week before her admission in the intensive care unit. The patient underwent a successful double-lung transplant after she failed treatment with immunosuppressive therapy, including tofacitinib. At 1-year follow-up, she had experienced no relapse of the disease. CASE REPORT This case includes a patient recently diagnosed with RPILD for whom no treatment showed efficacy, including glucocorticoids, cyclophosphamide, plasma exchanges, tofacitinib, and tacrolimus. She was placed under mechanical ventilation and venovenous extracorporeal membrane oxygenation 2 weeks after diagnosis in a bridge-to-transplant process. She was successfully transplanted 20 days later after having been registered on the French National Lung Transplant Waiting List with high priority. One year after surgery, her pulmonary function tests were good, and she showed no sign of relapse of anti-MDA5ab+ DM. CONCLUSIONS Lung transplantation can be a life-saving procedure in RPILD related to anti-MDA5ab+ DM. High-emergency allocation priority on the transplant list reduced the time between diagnosis and surgery. Patients without comorbidities should be promptly referred to specialized centers to rapidly assess the feasibility of transplantation in this context.

Abstract
Juvenile dermatomyositis (JDM) is an extremely heterogeneous orphan disease with limited amount of dedicated research on the subject matter. Recent research suggests that JDM may not just be the classic antibody driven complements mediated microangiopathy as was thought to be in the past. The etiopathogenesis of JDM also involves inappropriate stimulation of innate immune system followed by dysregulation of the adaptive immune response through dendritic cells. Many variable immune factors such as genetics, major histocompatibility complex expressions, immunohistochemical variabilities, and diversity in specific and associated autoantibodies may make individual IIM and JDM cases unique. The diversity in IIM and JDM also explains individual variability in response to specific therapies. Classifying and matching the right patients to the right treatment is crucial to the successful treatment of these patients with better outcomes. Sub-type specific biologic therapy may be the best current treatment that can match the patient to the best treatment options. A PubMed search was performed to find all the available cases of refractory myositis patients treated with biologics up to July 2020. Using this search this article reviews all the current biologic treatment options and experiences for both adults and children in the context of recent basic science to assist pediatric rheumatologists in choosing the optimal biologic therapy for a child with recalcitrant JDM.
