Safety of statin drugs in patients with dyslipidemia and stable systemic autoimmune myopathies.

Rheumatol Int 2018 Dec 5. Epub 2018 Dec 5.

Division of Rheumatology, Faculdade de Medicina FMUSP, Universidade de Sao Paulo, Sao Paulo, SP, Brazil.

Recent studies have shown a high prevalence of dyslipidemia in patients with systemic autoimmune myopathies (SAM). However, little is known about the safety of the use of statins in these patients, and this gap in research motivated the accomplishment of the present study. In a retrospective cohort study conducted from 2004 to 2018, 250 patients with SAM were evaluated, and 24 patients had stable forms of SAM (16 dermatomyositis, 1 polymyositis and 7 antisynthetase syndrome) but had dyslipidemia and had received statins.

Two cases of glutaric aciduria type II: how to differentiate from inflammatory myopathies?

Acta Clin Belg 2018 Nov 19:1-5. Epub 2018 Nov 19.

b Faculty of Medicine, Department of Rheumatology , Hacettepe University , Ankara , Turkey.

Muscle weakness is a nonspecific finding of myopathy of any etiology that include iatrogenic, toxic, endocrinological, infectious, immunologic, and metabolic disorders. Among the metabolic myopathies glutaric aciduria type II (GAII) is an autosomal recessively inherited rare disorder of fatty acid and amino acid metabolisms. The late onset form is heterogeneous in terms of symptomatology and severity and for the cases that chronic manifestations of lipid storage myopathy are the only clues for the disease, differential diagnosis can be challenging.

Induction of Osmolyte Pathways in Skeletal Muscle Inflammation: Novel Biomarkers for Myositis.

Front Neurol 2018 11;9:846. Epub 2018 Oct 11.

Department of Neurology and Neuromuscular Reference Center, Ghent University Hospital, Ghent, Belgium.

We recently identified osmolyte accumulators as novel biomarkers for chronic skeletal muscle inflammation and weakness, but their precise involvement in inflammatory myopathies remains elusive. In the current study, we demonstrate that, in myoblasts and myotubes exposed to pro-inflammatory cytokines or increased salt concentration, mRNA levels of the osmolyte carriers SLC5A3, SLC6A6, SLC6A12, and AKR1B1 enzyme can be upregulated. Induction of SLC6A12 and AKR1B1 was confirmed at the protein level using immunofluorescence and Western blotting. Read More

Assessment of renal function in patients with myositis and treated with subcutaneous immunoglobulin: a series of 24 cases.

Ther Adv Musculoskelet Dis 2018 Oct 7;10(10):201-207. Epub 2018 Oct 7.

Octapharma France, Boulogne-Billancourt, France.

Immunoglobulin (Ig) therapy is used to treat a wide range of immunodeficiencies and autoimmune diseases; While, its clinical benefit has been demonstrated in several studies, Ig therapy is associated with a risk of systemic adverse effects. As such, Onset of renal impairment, including acute renal failure, osmotic nephrosis and renal insufficiency, after immunoglobulin administration is rare, but is one of the most significant concerns related to intravenous Ig use at immunomodulatory doses. However, only few studies have investigated the safety of subcutaneous Ig (SCIg) in relation to these rare conditions. Read More

We attempted to clarify whether anti-MDA5-Ab is associated with long-term outcomes in patients with DM-ILD.

Methods: Thirty-six patients with DM-ILD were retrospectively analyzed for their serum anti-MDA5-Ab by using an enzyme-linked immunosorbent assay. Read More

Targeted capture sequencing identifies novel genetic variations in Chinese patients with idiopathic inflammatory myopathies.

Int J Rheum Dis 2018 Aug;21(8):1619-1626

Department of Rheumatology, Beijing Key Lab for Immune-Mediated Inflammatory Diseases, China-Japan Friendship Hospital, Beijing, China.

Objectives: Previous association studies have identified genetic variants in the human leukocyte antigen (HLA) complex as substantial risk factors for idiopathic inflammatory myopathies (IIMs). However, a great number of genes are located in the HLA region, and thus fine mapping is quite necessary.

Methods: Targeted capture sequencing were performed on the whole HLA region in 42 IIM patients and 24 healthy controls. Read More

Myositis autoantibody profiles and their clinical associations in Greek patients with inflammatory myopathies.

Clin Rheumatol 2018 Aug 25. Epub 2018 Aug 25.

Institute for Systemic Autoimmune and Neurological Diseases, Athens, Greece.

Myositis-specific (MSAs) or-associated autoantibodies (MAAs) have been linked to particular clinical phenotypes of idiopathic inflammatory myopathies (IIM) and appear to aid diagnosis. The objective of this study was to analyze the prevalence of MSAs and MAAs and their possible clinical associations in Greek IIM patients. This study comprised 95 IIM patients classified based on the 2017 EULAR/ACR classification criteria. Read More

STROBE: The correlation of Cyr61, CTGF, and VEGF with polymyositis/dermatomyositis.

Medicine (Baltimore) 2018 Aug;97(34):e11775

Department of Rheumatism and Immunology, Affiliated Hospital of Qinghai University, Xining.

This study aims to explore the roles of cysteine-rich protein 61 (Cyr61/CCN1), connective tissue growth factor (CTGF/CCN2) and vascular endothelial growth factor (VEGF) in the vascular process of polymyositis (PM)/dermatomyositis (DM).Real-time quantitative polymerase chain reaction was used to determine the mRNA expression of Cyr61, CTGF, and VEGF in muscle tissues of initially treated PM/DM patients and controls. Enzyme-linked immunosorbent assay (ELISA) was used to determine the serum levels of Cyr61, CTGF, and VEGF of initially treated PM/DM patients before and after treatment. Read More
