Pulmonary-Limited Granulomatosis with Polyangiitis Coexisting with Mixed Connective Tissue Disease.
In conclusion, we should recognize that GPA may develop during the disease course of MCTD even after prolonged disease remission. To prevent progression to an irreversible state, physicians should consider a surgical lung biopsy for the diagnosis in patients suspected of having pulmonary-limited GPA.

Antiribonuclease H2 antibodies are an immune biomarker for systemic lupus erythematosus.
Authors: Nozawa K, Doe K, Uomori K, Sekigawa I, Takasaki Y, Yamaji K, Tamura N Abstract We previously reported that autoantibodies against the proliferating cell nuclear antigen protein (PCNA)-binding protein chromatin assembly factor-1 (CAF-1) are specifically found in patients with systemic lupus erythematosus (SLE). PCNA and its complex constituents elicit autoimmune responses in patients with SLE, suggesting that autoantibody diversification likely occurs owing to epitope spreading. Therefore, we sought to clarify whether patients with SLE exhibit an autoimmune response to Ribonuclease H2 (RNase H2), another PC...

Idiopathic inflammatory myositis
1206Objectives: Idiopathic inflammatory myositis (IIM) is a group of connective tissue diseases characterized by proximal muscle weakness. IIM is frequently accompanied with interstitial lung disease (ILD) and malignancy. 18F-FDG PET/CT, a standard tool for diagnosing malignancies, can also be used to detect inflammatory lesions. However, about its usefulness in clinical course from diagnosis to treatment evaluation of IIM has not been well established. The aim of this study is to investigate the significance of PET/CT in the detection of malignancy and evaluation of muscular and pulmonary involvement in patients with IIM....

["Therapy-resistant polymyositis" - is the diagnosis correct?]
We report the case of a 32-year-old woman with severely elevated serum creatine kinase (CK; 80,000 U/l) and progressive proximal pareses. As muscular biopsy showed inflammatory infiltrates, polymyositis was suspected and immunosuppressive treatment was initiated. However, clinical improvement could not be achieved. Gene sequencing of the DYSF-gene showed a previously unreported homozygous mutation. In summary, elevated serum CK and inflammatory infiltrates in the muscle biopsy are not specific for polymyositis, but may also occur in degenerative diseases (muscular dystrophy), such as dysferlinopathy. ...

Mitochondrial Skeletal and Cardiac Myopathy Responsive to Aggressive Immunosuppression in Rapidly Progressing Systemic Sclerosis (P5.077)
Conclusions:Perivascular epimysial inflammation is rarely seen in any disease. Mitochondrial myopathy without myositis has not been reported in systemic sclerosis. We propose that ischemia caused by vasculopathy and fibrosis in systemic sclerosis, together with subclinical mitochondrial pathology, severely affected skeletal and cardiac muscle due to their high metabolic demands. An unusual presentation of myopathy in autoimmune disease suggests an underlying latent pathology, such as mitochondrial myopathy. Rapidly progressing autoimmune disease necessitates aggressive immunosuppression.Disclosure: Dr. Yeo has nothing to d...

401 Cancer risk in clinically amyopathic dermatomyositis: A retrospective cohort study at four tertiary care centers
Clinically amyopathic dermatomyositis (CADM), characterized by pathognomonic cutaneous findings without muscle weakness, is an important subset and accounts for 20% of patients with dermatomyositis (DM). In patients with CADM, limited literature exists regarding the associated risk of malignancy as most studies have focused on classic DM or polymyositis. Therefore, we investigated the association between CADM and cancer at 4 tertiary care centers. Using the Partners Healthcare and New York University medical record systems, we reviewed the medical records of all patients with CADM treated between 2000 and 2016. (Source: Jo...

Immune ‐Array Analysis in Sporadic Inclusion Body Myositis Reveals HLA–DRB1 Amino Acid Heterogeneity Across the Myositis Spectrum
ConclusionThis is the largest, most comprehensive genetic association study to date in IBM. The data confirm that HLA is the most strongly associated region and identifies novel amino acid associations that may explain the risk in this locus. These amino acid associations differentiate IBM from polymyositis and dermatomyositis and may determine properties of the peptide‐binding groove, allowing it to preferentially bind autoantigenic peptides. A novel suggestive association within the chromosome 3 p21.31 region suggests a role for CCR5. (Source: Arthritis and Rheumatism)

Thigh muscle MRI in immune-mediated necrotising myopathy: extensive oedema, early muscle damage and role of anti-SRP autoantibodies as a marker of severity
Objectives The aims of this study were to define the pattern of muscle involvement in patients with immune-mediated necrotising myopathy (IMNM) relative to those with other inflammatory myopathies and to compare patients with IMNM with different autoantibodies. Methods All Johns Hopkins Myositis Longitudinal Cohort subjects with a thigh MRI (tMRI) who fulfilled criteria for IMNM, dermatomyositis (DM), polymyositis (PM), inclusion body myositis (IBM) or clinically amyopathic DM (CADM) were included in the study. Muscles were assessed for intramuscular and fascial oedema, atrophy and fatty replacement. Disease subgroups wer...

Increased risk of comorbid rheumatic disorders in vitiligo patients: A nationwide population ‐based study
Abstract Vitiligo is a common acquired depigmentation disorder. Previous studies have shown that vitiligo is associated with a variety of autoimmune disorders. However, a large‐scale epidemiological study focused on comorbid rheumatic disorders has not been undertaken. To clarify the associations between vitiligo and various rheumatic disorders, we performed a cross‐sectional study using data from the Korean National Health Insurance claims database. Between 2009 and 2013, totals of 86 210 patients with vitiligo and 172 420 age‐ and sex‐matched controls without vitiligo were enrolled in this study. Vitiligo patient...
