Juvenile dermatomyositis/polymyositis and lymphoma
The objective of this literature review was to assess for any association between, and disease profile of, JDM/PM and lymphoma in childhood. Risk determinants of the possible development of lymphoma in the pediatric population with JDM/PM appear to be the degree and duration of inflammatory activity with chronic B-cell activation and/or antigen stimulation; a paraneoplastic relationship is unlikely.

Identification of Palmitoleic Acid Controlled by mTOR Signaling as a Biomarker of Polymyositis.
In this study, we aim to figure out the role of mTOR signaling in the development of polymyositis and identify novel biomarkers for the detection and therapy of polymyositis. After screening and validation, we found that palmitoleic acid, a monounsaturated fatty acid, is highly regulated by mTOR signaling. Inhibition of mTORC1 activity decreases palmitoleic acid level. Moreover, mTORC1 regulates the level of palmitoleic acid by controlling its de novo synthesis. Importantly, increased palmitoleic acid has been proven to be a marker of polymyositis. Our work identifies palmitoleic acid in peripheral blood mononuclear cells ...

Predictive factors for long-term outcome in polymyositis/dermatomyositis-associated interstitial lung diseases
Conclusions Patients with PM/DM/CADM-ILD are at risk for chronic respiratory failure due to the deterioration of ILD during long-term follow-up. The presence of anti-PL-7 antibody and a lower %FVC at initial diagnosis may predict long-term deterioration in patients with PM/DM/CADM-ILD. (Source: Respiratory Investigation)

A study of acute muscle dysfunction with particular reference to dengue myopathy
Conclusion: Dengue infection and hypokalemia due to various causes are the most common causes of acute myopathy and are associated with rapid and complete recovery within 1 month. Shorter duration of illness, higher MRC sum score, better disability status at presentation, lower serum CK correlate with better outcome. Biopsy was decisive in <20% cases; hence, it is not primary investigation in acute myopathy. (Source: Annals of Indian Academy of Neurology)

Association between rheumatic diseases and cancer: results from a clinical practice cohort study
AbstractThe association between cancer and immune-mediated rheumatic conditions is controversial, especially as far as polymyalgia rheumatica (PMR) is concerned. Furthermore, no clinical feature has been shown to be suggestive of a paraneoplastic rheumatic syndrome. With the present study, we aim to address both these issues. The study population comprisedN = 1750 patients, includingN = 100 with PMR, who attended our tertiary immuno-rheumatology clinic between January 1, 2005 and November 30, 2012. A rheumatic disease was deemed paraneoplastic if cancer had been diagnosed in the 2 years preceding or following its onse...

Direct suppression of autoaggressive CD8+ T cells with CD80/86 blockade in CD8+ T cell-mediated polymyositis models of mice.
CONCLUSIONS: The CD80/86 blockade was effective in PM models of mice. Amelioration of CPIM indicates direct suppression of CD8+ T cells by the CD80/86 blockade. CTLA4-Ig should be a potential therapeutic agent of PM and other CD8+T cell-mediated diseases by suppressing both autoantigen-specific CD4+ and CD8+ T cells.

Use of intravenous immunoglobulin therapy for myositis: an audit in South Australian patients
In South Australia, between 2000 and 2014, 57 patients with idiopathic inflammatory myositis (IIM) were treated with intravenous immunoglobulin (IVIg). We reviewed disease characteristics to determine predictors of response to therapy and IVIg dosing and duration to identify opportunities to rationalise IVIg use. Patients with dermatomyositis/polymyositis had a response rate of 77% and were more likely than inclusion body myositis to respond to therapy. Consideration should be given to the use of the lowest possible dose of IVIg and to the undertaking of trials of cessation of IVIg in patients with stable IIM. (Source: Int...

Serum level of DNase1l3 in patients with dermatomyositis/polymyositis, systemic lupus erythematosus and rheumatoid arthritis, and its association with disease activity
AbstractDNase1l3 is an endonuclease to degrade the chromatin of apoptotic or necrotic cells. Serum DNase1l3 may fulfill the function of clearance of chromatin released into the circulation by dying cells, which can trigger autoimmune responses. To date, it remains unclear whether serum DNase1l3 level associates with the pathogenesis of autoimmune diseases. Sixty-eight patients with dermatomyositis/polymyositis (DM/PM,n = 30), systemic lupus erythematosus (SLE,n = 20) and rheumatoid arthritis (RA,n = 18), as well as 26 healthy blood donors were enrolled in the present study. Serum levels of DNase1l3 were quantified by...

Rituximab in the treatment of inflammatory myopathies: a review
Several uncontrolled studies have encouraged the use of rituximab (RTX) in patients with myositis. Unfortunately, the first placebo-phase trial to assess the efficacy of RTX in refractory myositis did not show a significant difference between the two treatment groups, and doubts have been expressed about its study design. In this review we present an up-to-date overview of the reported experiences of RTX therapy in myositis. A PubMed search was performed to find all the available cases of refractory myositis patients treated with RTX up to July 2015. The following terms were assessed: inflammatory myopathies OR anti-synthe...

The host defense peptide LL-37 a possible inducer of the type I interferon system in patients with polymyositis and dermatomyositis.
In conclusion, the present study supports our hypothesis that LL-37 may activate type I IFNs, which could initiate and perpetuate an inflammatory process. The prolonged exposure of the immune system to type I IFNs may eventually break tolerance and lead to autoimmune myositis.

SPARC Interacts with Actin in Skeletal Muscle in Vitro and in Vivo.
We report that these mice develop normal skeletal muscle with retained ability to regenerate. However, when we subject muscle from SPARC-deficient mice to an in vitro fatigue stimulation protocol, we find a defective force recovery. Therefore, SPARC appears to be an important modulator of the actin cytoskeleton, implicating maintenance of muscular function. This direct interaction with actin suggests a new role of SPARC during tissue remodeling. PMID: 27908613 [PubMed - as supplied by publisher] (Source: Am J Pathol)

The sphingosine-1-phosphate receptor: A novel therapeutic target for multiple sclerosis and other autoimmune diseases.
Abstract Multiple sclerosis (MS) is a prototype autoimmune disease of the central nervous system (CNS). Currently, there is no drug that provides a cure for MS. To date, all immunotherapeutic drugs target relapsing remitting MS (RR-MS); it remains a daunting medical challenge in MS to develop therapy for secondary progressive MS (SP-MS). Since the approval of the non-selective sphingosine-1-phosphate (S1P) receptor modulator FTY720 (fingolimod [Gilenya®]). for RR-MS in 2010, there have been many emerging studies with various selective S1P receptor modulators in other autoimmune conditions.

We aimed to examine the frequency, nature and outcome of malignant neoplasms in a group of patients with IPF or collagen vascular disease-associated interstitial lung disease (CVD-ILD).Of 343 patients referred to the Pulmonology Department, Ege University Hospital with IPF or CVD-ILD, 30 developed a malignant neoplasm. Fifteen had IPF, 14 CVD-ILD (3 Sjögren's syndrome, 3 progressive systemic sclerosis, 3 polymyositis, 5 undifferentiated-CVD), and 1 Behcet's disease. 23 ...
