Cutaneous ulceration in dermatomyositis: association with anti-melanoma differentiation-associated gene 5 antibodies and interstitial lung disease. Arthritis Care Res (Hoboken) 2015; 67:667-72. [PMID: 25331610 DOI: 10.1002/acr.22498] [Citation(s) in RCA: 113] [Impact Index Per Article: 12.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Revised: 09/29/2014] [Accepted: 10/07/2014] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To identify clinical and serologic correlates of cutaneous ulcers in dermatomyositis (DM). METHODS We retrospectively examined a cohort of 152 DM patients. We compared the features of patients with ulcers to those without ulcers using chi-square or Fisher's exact tests and used univariate and multivariate logistic regression models to assess the association between ulcers and clinical features such as malignancy, interstitial lung disease (ILD), and amyopathic disease. RESULTS Forty-three patients (28%) had cutaneous ulcers. Nearly half the patients had ulcers present in more than 1 location: 24 (56%) had ulcers over the extensor surfaces of joints, 18 (42%) at the digital pulp or periungual areas, and 25 (58%) had ulcers located elsewhere. In univariate analysis ulcers were associated with Asian race, but not with other clinical and demographic features, including malignancy or ILD. In multivariate analysis ulcers were significantly associated with anti-melanoma differentiation gene 5 (anti-MDA5) antibodies (odds ratio 10.14, 95% confidence interval 1.95-52.78; P = 0.0059) and this was greatest for ulcers located at the digital pulp. In patients with cutaneous ulcers, ILD risk was specifically increased only in patients with anti-MDA5-positive antibodies. CONCLUSION We confirmed the strong association between anti-MDA5 antibodies and cutaneous ulcers, with the novel finding that the association of cutaneous ulcers with ILD depends upon the presence of anti-MDA5 antibodies. DM patients who display this cutaneous phenotype should undergo appropriate evaluation for ILD.

Abstract
To study the clinical features and associated risk factors of interstitial lung disease (ILD) in clinically amyopathic dermatomyositis (CADM) in Chinese patients. Forty-one Chinese Han patients with a diagnosis of CADM in West China Hospital from August 2008 to 2011 were retrospectively analyzed. The prevalence of ILD in CADM patients is 60.98 %, in which 26.83 % for acute/subacute interstitial pneumonia (A/SIP) and 34.15 % for chronic interstitial pneumonia (CIP). Mortality of A/SIP is 63.64 %, with a 6-month survival rate of 54.50 %. Levels of erythrocyte sedimentation rate, serum ferritin, alanine aminotransferase, aspartate aminotransferase, creatine kinase, lactate dehydrogenase, hydroxybutyric dehydrogenase, and immunoglobulin A (IgA) are higher in CADM-ILD patients than CADM patients without ILD. Levels of serum ALB and lymphocyte count in peripheral blood are significant lower in A/SIP than in CIP group. Sign of ground glass opacities in high-resolution computed tomography (HRCT) images is more common in A/SIP group, and diffusion function is worse in these patients compared with CIP group. The prevalence of ILD in Chinese CADM patients is strikingly high, and A/SIP is a major cause of death in CADM patients. Laboratory findings combined with HRCT examination and pulmonary function tests can provide valuable predictive information of ILD or A/SIP in CADM patients.

Abstract
Before the use of corticosteroids, the prognosis for polymyositis/dermatomyositis (PM/DM) was extremely poor. To date, although overall prognosis appears to be better, PM and DM are still considered to be associated with increased morbidity, primarily related to severe muscle weakness and visceral involvement. Recent series underline that only 20% to 40% of treated patients will achieve PM/DM remission, whereas 60% to 80% will experience a polycyclic or chronic, continuous course of the disease. PM/DM further continues to have a great impact on life in medium- and long-term follow-up, as up to 80% of treated patients are still disabled (using Health Assessment Questionnaire scores). The overall mortality ratio in PM/DM patients also remains threefold higher compared with the general population, with cancer, lung, and cardiac complications and infections being the most common causes of deaths. Predictive factors for a poor prognosis in PM/DM patients are older age, involvement of lung and cardiac systems, dysphagia, cancer, and serum myositis-specific antibodies (including coexistent presence of anti-Ro52 and anti-Jo1 antibodies, anti-signal recognition particle antibody, anti-155/140, and anti-CADM-140 antibodies).

Abstract
OBJECTIVE To analyze clinical characteristics, survival, causes of death, and risk factors associated with mortality in patients with adult-onset idiopathic inflammatory myopathies (IIM) in Japan. METHODS We retrospectively investigated 197 patients diagnosed with adult-onset IIM at our hospital from 1984 to 2009 according to Bohan and Peter criteria for polymyositis (PM)/dermatomyositis (DM) and modified Sontheimer's criteria for clinically amyopathic DM (ADM). RESULTS Survival in the whole group at 1, 5, and 10 years was 85%, 75%, and 67%, respectively. Mortality in cancer-associated myositis was the worst (25% at 5 yrs), followed by clinically ADM (61% at 5 yrs) and primary DM (77% at 5 yrs). Primary DM had significantly low survival compared to primary PM (91% at 5 yrs; p = 0.0427). Among the 53 patients who died were 6 patients with ADM (11%) and 20 patients with primary DM (38%). Interstitial lung disease (ILD) was the main cause of death in clinically ADM (71%) and primary DM (60%), most of which occurred within the first few months. Fewer patients died in primary PM (9%) and overlap myositis (13%). Independent risk factors for death were older age (HR 1.031; 95% CI 1.009-1.053) and skin ulcers (HR 3.018; 95% CI 1.340-6.796) in the whole group and ILD with mild serum creatine kinase levels (< 500 IU/l; HR 3.537; 95% CI 1.260-9.928) in primary DM. CONCLUSION Survival of clinically ADM and primary DM was low, mainly due to fatal ILD, compared to primary PM. Establishing therapeutic strategy for ILD may improve the survival in our patient population.

The mucocutaneous and systemic phenotype of dermatomyositis patients with antibodies to MDA5 (CADM-140): a retrospective study. J Am Acad Dermatol 2011; 65:25-34.

Abstract
BACKGROUND Dermatomyositis (DM) is a multisystem autoimmune disease, in which serologic evidence of immune responses to disease-specific antigenic targets is found in approximately 50% to 70% of patients. Recently, melanoma differentiation-associated gene 5 (MDA5) has been identified as a DM-specific autoantigen that appears to be targeted in patients with DM and mild or absent muscle inflammation and with an increased risk of interstitial lung disease. OBJECTIVE We wished to understand the role of MDA5 in DM skin inflammation by testing it to determine if a specific cutaneous phenotype is associated with MDA5 reactivity. METHODS We retrospectively screened plasma from 77 patients with DM in the outpatient clinics at the Stanford University Department of Dermatology in California. RESULTS We found that 10 (13%) patients had circulating anti-MDA5 antibodies, and had a characteristic cutaneous phenotype consisting of skin ulceration, tender palmar papules, or both. Typical areas of skin ulceration included the lateral nailfolds, Gottron papules, and elbows. Biopsy specimens of the palmar papules showed a vasculopathy characterized by vascular fibrin deposition with variable perivascular inflammation. Patients with anti-MDA5 antibodies also had an increased risk of oral pain and/or ulceration, hand swelling, arthritis/arthralgia, and diffuse hair loss. Consistent with previous reports, these patients had little or no myositis and had increased risk of interstitial lung disease. LIMITATIONS This study was conducted at a tertiary referral center. Multiple associations with MDA5 antibodies were tested retrospectively on a relatively small cohort of 10 anti-MDA5-positive patients. CONCLUSION We suggest that MDA5 reactivity in DM characterizes a patient population with severe vasculopathy.

Abstract
Cutaneous ulcers associated with vasculitis are rarely reported in adult-onset dermatomyositis (DM), and are often resistant to treatment, resulting in a poor prognosis. There is no general treatment strategy and the effects of various treatments have never been confirmed histopathologically. A 43-year old man with DM developed refractory multiple cutaneous ulcers which were revealed as vasculitis by skin biopsy. Repeated intravenous cyclophosphamide pulse therapy (IV-CY) without high-dose corticosteroid therapy resulted in complete resolution of the ulcers without adverse effects or severe complications. A repeat biopsy confirmed complete remission of vasculitis. Repeated IV-CY is a useful treatment for induction of clinical remission of DM with cutaneous vasculitis.

Abstract
Lipomembranous changes are histological findings without specific clinical correlations, and are thought to be related to vascular impairment in fatty tissue. We describe a case of systemic lupus erythematosus (SLE) in which subcutaneous induration of the lower leg showed lipomembranous changes and calcification. This patient showed thrombophilia with thrombosis of the femoral and iliac veins, and cerebellar and myocardial infarction. A biopsy specimen from the subcutaneous tissue surrounding the multiple leg ulcers revealed degeneration of fat cells, lipomembranous changes in the fatty tissues, and calcification. Another biopsy specimen from the outer edges of the ulcers showed microthrombi and fibrinoid changes in the vessel walls, and mononuclear cell infiltrates in the dermis. Lipomembranous changes have been seen in connective tissue disorders such as lupus profundus, morphoea, systemic sclerosis, and panniculitis associated with dermatomyositis, but rarely associated with SLE. We speculate that ischaemic changes due to the vascular disturbance of the lower legs may have induced lipomembranous changes and calcification in the subcutaneous tissues in the present case.

Abstract
UNLABELLED The second part of our review of panniculitis summarizes the clinicopathologic features of the mostly lobular panniculitides. Erythema induratum of Bazin (nodular vasculitis) represents the most common variant of lobular panniculitis with vasculitis, although controversy persists about the nature of the involved vessels. Mostly lobular panniculitides without vasculitis comprise a series of disparate disorders. These include sclerosing panniculitis that results from chronic venous insufficiency of the lower extremities; panniculitis with calcification of the vessel walls such as calciphylaxis and oxalosis; and inflammatory diseases with crystals within the adipocytes such as sclerema neonatorum, subcutaneous fat necrosis of the newborn, and poststeroid panniculitis. Connective tissue diseases, such as systemic lupus erythematosus and dermatomyositis, pancreatic diseases, and alpha(1)-antitrypsin deficiency may also show a mostly lobular panniculitis with characteristic histopathologic features. Lobular panniculitis may also be an expression of infections, trauma, or factitial causes involving the subcutaneous fat. Lipoatrophy refers to a loss of subcutaneous fat due to a previous inflammatory process involving the subcutis, and it may be the late-stage lesion of several types of panniculitis. In contrast, lipodystrophy means an absence of subcutaneous fat with no evidence of inflammation and often the process is associated with endocrinologic, metabolic, or autoimmune diseases. Finally, cytophagic histiocytic panniculitis is the term that has been used to describe two different processes: one is inflammatory, a lobular panniculitis, and the other one is neoplastic, a subcutaneous T-cell lymphoma. The only common feature of these two different processes is the presence of cytophagocytosis in the lesions. (J Am Acad Dermatol 2001;45:325-61.) LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with the pathogenesis, clinical manifestations, histopathologic findings, and treatment options for the most frequent variants of the lobular panniculitides.

Abstract
Unusual histopathologic structures were observed in lobular panniculitis of a patient with Behçet's disease. These were polyp-like in shape and protruded into cavities made of lysed fat cells. Various stages of development were observed. To determine the origin of cells making up these structures, we applied various histochemical and immunohistochemical techniques and found the cells to be histiocytes (macrophages) engaged in phagocytizing degenerated fat cells and cell membranes which had formed into membranocystic lesions.
