et al. New classification criteria by the European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) for adult and juvenile idiopathic inflammatory myopathies were recently published that included one MSA – anti-Jo1 antibody [16]. Interstitial lung disease (ILD) accompanied by anti-melanoma differentiation-associated gene 5 (MDA5) positive dermatomyositis (DM) is often rapidly progressive and associated with poor prognosis. RP-ILD is defined as progressive interstitial lung disease (ILD) within 3 months of the onset of respiratory symptoms [5]. Other autoantibodies studied including anti-Scl-70, anti-Jo-1, anti-double stranded DNA and anti-cyclic citrullinated peptide were negative. because of heliotrope rash, Gottron’s sign and papules, shawl sign, periungueal teleangectasias, mechanic’s hands and subcutaneous calcinosis appeared 2 months before. A recent study by Xu et al. 2009;60(7):2193–200. AR, BP, FL and CS wrote the case reports and helped drafting the manuscript; PP conceived the study, coordinated it and drafted the manuscript.

Article  CS corticosteroids (methilprednisolone, prednisone); CyA cyclosporine A; IVIg immunoglobulins; HyQ hydroxychloroquine. Arthritis Rheum. Eur Respir Rev. Owing to high mortality, treatment for anti-MDA5 antibody-positive JDM should be individualized as early intensification of therapy in those with a poor response may be vital. This book was a result of an extended coordinated collaboration of one-hundred and fifty-four distinguished scientists from thirty-one countries around the globe. The Guest Editors have assembled international experts in rheumatology to present an update to pediatricians. This seems to be slightly above the percentages found in American studies (6 and 7 %, respectively) [36, 37]. The hallmarks are palmar papules, cutaneous ulceration, a high risk of severe interstitial lung disease (ILD), a low risk of myositis, and a low risk of malignancy. This new edition of Muscle Disease: Pathology and Genetics will be a very valuable resource for clinicians, pathologists, geneticists and basic neuroscientists involved in diagnosis, research, treatment and management of patients with ... CADM complicated with malignancy occurs less frequently than similarly complicated dermatomyositis and, to the best of our knowledge, this is the first case of CADM complicated with two cancers. Terms and Conditions, She had no muscle weakness. 2010;11:997–1004. Semin Arthritis Rheum. Google Scholar. In addition to heliotrope rash, Gottron and shawl sign, skin (and mucosa) involvement actually covers a wide spectrum of manifestations, including papules (frequently tender on palm), plaques, nodules and ulcerations. Kumakura S, Murakawa Y. 2018;37(7):1983–9. Her lack of initial treatment response and the rapid development of PNM was concerning, especially because literature has reported significantly higher mortality in adult anti-MDA5 antibody-positive dermatomyositis patients with PNM [7]. The authors declare that they have no competing interests.

Serum interferon-α is a useful biomarker in patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis. As a fact, no extensive study comparing the efficiency of the different methods to detect anti-MDA5 has been produced so far. Polymyositis and dermatomyosits. Formal written consent for publication was obtained from the patient and her mother and is available on request. The p155 recognized by anti-TIF-1ɣ and the small ubiquitin like modifier activating enzyme heterodimer eliciting anti-SAE have been related to malignancy in adults and severe course of DM, respectively [1, 25, 27]. PubMed  2014;233:258–68. PubMed Google Scholar. INTRODUCTION Dermatomyositis (DM) is an idiopathic inflamma- Rheumatology (Oxford). Two doses of oral methotrexate (MTX) were given but discontinued due to new elevation of ALT up to 400 U/L. Also, spontaneous pneumomediastinum (PNM) is an important complication to be aware of as there is evidence that it leads to a higher mortality [7].

Follow up chest CT after 2 months showed interval resolution of consolidative changes with replacement by fibrosis (Fig. Prescription of tacrolimus was stopped to avoid over-immunosuppression. Malignancies in classic DM included lung (3 patients), colon (2 patients) and bladder, lymphoma, breast, oropharynx, external auditory canal and unknown (1 patient each) while CADM included colon (1 patient). By using this website, you agree to our As a fact, European patients with circulating anti-MDA5 autoantibodies may be clinically inhomogeneous and exhibit different rates of severity. In the early nineties classification criteria of CADM were proposed but never validated [33] and association with cancer and ILD was found. 2013;4:319. Fiorentino D, Chung L, Zwerner J, Rosen A, Casciola-Rosen L. The mucocutaneous and systemic phenotype of dermatomyositis patients with antibodies to MDA5 (CADM-140): a retrospective study. 2013;9:e1003222. Pulmonary function test showed reduced diffusing capacity for carbon monoxide (DLCO) to 59% of the predicted value. There was hyperpigmentation over the dorsal surface of interphalangeal joints, but no definite Gottron’s papules. From the prognostic standpoint, knowing that a patient is anti-MDA5 antibody positive is valuable because adult studies have demonstrated these patients are at risk for development of RP-ILD which is the major cause of the high mortality. 3). Poddighe D, Cavagna L, Brazzelli V, Bruni P, Marseglia GL. Niewold TB. Physical examination revealed arthritis of fingers and wrists, ulcers and palmar papules over fingers, hyperpigmentation of interphalangeal joints, and rash over the neck. In the pediatric population, Sabbagh et al. 2015;9(Suppl 1):9–17. Paola Parronchi. This likely remodels organelle membranes and activates the expression of several anti-viral defense factors including Interferons (IFNs). Mod Rheumatol. Ann Rheum Dis. Yamaguchi K, Yamaguchi A, Itai M, Kashiwagi C, Takehara K, Aoki S, et al. 2019;78(7):988–95. The use of rituximab in RP-ILD with positive anti-MDA5 antibody appeared promising in an adult case series [23], however there are few reports on its use in pediatric patients with the antibody. Background/Purpose: Anti-CADM-140/ Melanoma Differentiation-Associated Gene 5 (MDA5) antibody is found specifically in patients with dermatomyositis (DM). She was treated according to adult guidelines with steroid and calcineurin inhibitor. J Pathol. https://doi.org/10.1007/s10067-018-4122-2. Other than these features, the interphalangeal joint hyperpigmentation should alert one to dermatomyositis. Anti-melanoma differentiation-associated gene 5–positive dermatomyositis (MDA5 + DM) is a rare autoimmune disease predominantly reported in East Asia. Videofluoroscopic swallowing study showed mild pharyngeal dysphagia. 2010;49:433–40. She also complained of painful swelling of fingers for 3 weeks. Electromyography showed mild myopathic signs. Dermatomyositis with positive anti-MDA5 antibody has a distinct phenotype in terms of skin, joint, muscle, and lung involvement in both children and adults. Sato S, Kuwana M, Fujita T, Suzuki Y. Anti-CADM-140/MDA5 autoantibody titer correlates with disease activity and predicts disease outcome in patients with dermatomyositis and rapidly progressive interstitial lung disease. Anti-transcriptional intermediary factor 1y antibodies (TIF-1y, anti 155/140) are strongly associated with malignancy-related dermatomyositis in the elderly. Competing interests The authors declare that they have no competing interests. Genome-wide association scan in women with systemic lupus erythematosus identifies susceptibility variants in ITGAM, PXK, KIAA1542 and other loci. This book is a collection of case-based questions, directed towards and meticulously selected to cover the most common and important aspects of pediatric autoimmune disorders. between anti-MDA5 DM and SJS. Aimed at the diagnostic pathologist and neurologist, this text is organized by disease, with introductory chapters on morphology, immunology, pathogenesis and biopsy technique. Severe involvement of eyelids at the admission into the Dept. in 2019 reported the use of tofacitinib, a JAK inhibitor, leading to clinical improvement within 6 months in two anti-MDA5 antibody-positive JDM refractory to multiple agents including rituximab [26]. Anti-MDA5 autoantibodies mark a subtype of DM of high severity in Asians whereas a highly variable clinical presentation is seen in the Caucasian population. Further, gain-of-function mutations of MDA5 were identified in the monogenic interferonopathy Aicardi-Goutières Syndrome (AGS) and neuro-inflammatory phenotypes characterized by an IFN-alfa signature. PubMed  The interplay between CADM and interstitial lung disease is more intriguing. A recent retrospective study partially confirms these findings as ulcers did not significantly associate with myopathy or other classical clinical features of DM (dysphagia, Raynaud’s or joint pain) but more commonly affected Asian patients. The diagnostic utility of anti-melanoma differentiation-associated gene 5 antibody testing for predicting the prognosis of Japanese patients with DM. complicated with malignancy occurs less frequently than similarly complicated dermatomyositis and, to the best of our knowledge, this is the first case of CADM complicated with two cancers. Unterholzner L. The interferon response to intracellular DNA: why so many receptors? Google Scholar. The V proteins of paramyxoviruses bind the IFN-inducible RNA helicase, mda-5, and inhibit its activation of the IFN-beta promoter. Found insideUnique in its attention to the pathophysiology, clinical diagnosis, and management of these disorders, this book is illustrated with many tables, illustrative figures and clinical color photographs. It has a bimodal age of presentation depending on the variant: 1. juvenile dermatomyositis (JDM): affects children and tends to be more severe 2. adult dermatomyositis (ADM): typically affects adults around the age of 50 1. interstitial lung disease 2: typically gives a patchy and subpleural consolidation with parenchymal bands 2. DM is a rare autoimmune disease characterized by skin involvement, striate muscle inflammation which may include the upper oesophagus and possible damage of internal organs frequently marked by the presence of autoantibodies [23]. N Engl J Med. Tansley SL, Betteridge ZE, McHugh NJ. Melanoma differentiation-associated gene 5 (MDA5) is an autoantigen target that has been described in individuals with dermatomyositis (DM). Anti-MDA5 antibody was detected in the myositis-specific antibody (MSA) panel, but quantitative test for the antibody was not available. Her chest radiograph showed left perihilar opacity. In retrospect, she already had interstitial lung disease at first presentation manifested as cough and opacity on chest radiograph, which was later confirmed with chest computed tomography. Unterholzner L, Keating SE, Baran M, Horan KA, Jensen SB, Sharma S, Sirois CM, Jin T, Latz E, Xiao TS, Fitzgerald KA, Paludan SR, Bowie AG. It could also be attributed to the lack of ILD grading parameters to guide further studies. However, the decision to intensify treatment is based solely on clinician’s opinion. These results suggest that DM patients with anti-CADM-140/ MDA5 antibody might have a low risk of malignancy. Similarly to RIG-I, MDA5 consists in two N-terminal caspase recruitment domains (CARDs), two DExD/H-box helicase domains and a C-terminal domain (CTD). Heliotrope rash rapidly improved and facial oedema reduced as well (Fig. Natural Autoantibodies provides an in-depth analysis of all aspects of natural antibodies. The book examines the advantages and pitfalls of every type of technique that is widely used for detecting autoantibodies. In: Hollander JL, McCarty DJ, editors. Ladislau et al. 2012;64(10):1602–10.

Dermatomyositis and polymyositis: clinical presentation, autoantibodies, and pathogenesis. Chest computed tomography (CT) showed multiple subpleural and peripherally located consolidations in both lungs (Fig. If additional examples are reported, a more clear association may be appreciated. 2006;54:597–613. Recognition of foreign or host DNA indeed induces IFN-alfa production via Toll-like receptor (TLR) 9 and/or cytosolic DExD/H-box helicase-containing sensors, but these latter do not include RLRs. She was given empirical low flow oxygen supplement. However, the association of malignancy and anti-CADM-140/ MDA5 antibody had not been examined in detail. Google Scholar.
