Common and rare forms of vasculitis associated with Sjögren's syndrome

Purpose of review Although uncommon, systemic vasculitis is one of the most severe extraglandular manifestations of primary Sjögren's syndrome (pSS) accounting for the increased morbidity and mortality of the disease. This review aims to describe major previous and recent reports regarding the clinical presentation, prognosis and treatment of systemic vasculitis associated with pSS. Recent findings Both older and recent pSS cohort studies performed over the past several and recent years, have clearly shown that cryoglobulinaemic vasculitis is the most frequent type of systemic vasculitis accompanying pSS. Antineutrophil cytoplasmic antibody-associated, large and medium vessel vasculitis are described only in sporadic cases. In addition to the overt clinical manifestations of cryoglobulinaemic vasculitis, type II cryoglobulinaemia, glomerulonephritis and purpura have been correlated with increased risk for B-cell non-Hodgkin lymphoma (NHL) in pSS. Summary pSS is characterized by autoreactive B and T-cell infiltrates around the epithelial structures of the affected organs, as well as, B-cell hyperreactivity. The latter, is attested by the increased production of autoantibodies, directed against many different organ and nonorgan self-antigens. Vasculitis is a significant and potentially life-threatening complication of the disease depending on the size, localization, histologic type and the pathogenetic mechanisms of the inflammatory process. The potentially irrever...

In conclusion, we show a novel mouse model of coronary stenosis induced by LCWE that is characterized by coronary stenosis with severe coronary vasculitis and elastin degradation. In addition, VSMC proliferation plays an important role in the formation of coronary stenosis. This model is an appropriate model of KD coronary stenosis.

To investigate the clinical implications of SF3B1 and ring sideroblasts in myelodysplastic syndrome-refractory cytopenia with multilineage dysplasia (MDS-RCMD), 238 consecutive MDS-RCMD patients were included in this study. Our results showed that SF3B1 mutation in MDS- RCMD patients identifies a homogenous phenotype characterized by homogeneous hematologic features including a high prevalence of erythroid dysplasia and a high proportion of ring sideroblasts, prolonged survival and reduced leukemic transformation.

The anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) are a group of life-threatening multi-system diseases characterized by necrotising inflammation of small blood vessels and crescentic glomerulonephritis. ANCA are thought to play a direct pathogenic role. Previous studies have shown that spleen tyrosine kinase (SYK) is phosphorylated during ANCA-induced neutrophil activation in vitro. However, the role of SKY in vivo is unknown. Here, we studied its role in the pathogenesis of experimental autoimmune vasculitis, a pre-clinical model of myeloperoxidase-ANCA-induced pauci-immune systemic vasculitis i...

AbstractObinutuzumab is a glycoengineered tumor-targeting anti-CD20 mAb with a modified crystallizable fragment (Fc) domain designed to increase the affinity for the Fc γRIIIA/CD16 receptor, which was recently approved for clinical use in CLL and follicular lymphoma. Here we extend our previous observation that, in human NK cells, the sustained CD16 ligation by obinutuzumab-opsonized targets leads to a markedly enhanced IFN-γ production upon a subsequent cytokine re-stimulation. The increased IFN-γ competence in response to IL-2 or IL-15 is attributable to post-transcriptional regulation, as it does not c...

Hepatitis C virus (HCV) infection is associated with tremendous morbidity and mortality due to liver complications. HCV infection is also associated with many extrahepatic manifestations including cardiovascular diseases, glucose metabolism impairment, cryoglobulinemia vasculitis, B cell non-Hodgkin lymphoma and chronic kidney disease (CKD). Many studies have shown a strong association between HCV and CKD, by reporting (i) an increased prevalence of HCV infection in patients on haemodialysis, (ii) an increased incidence of CKD and proteinuria in HCV-infected patients, and (iii) the development of membranoproliferative glom...

Abstract Cryoglobulinemic vasculitis (CV) is a small-to-medium-vessel vasculitis that appears in 10–15 % of patients chronically infected with hepatitis C virus (HCV). The classic symptom triad of CV, purpura/asthenia/arthralgia, is accompanied by clinical features that include glomerulonephritis, neuropathy, interstitial pneumonitis, and cardiomyopathy, ranging in their severity from mild to life threatening. The risk of developing non-Hodgkin lymphoma is also higher. The cumulative 10-year survival rate of CV patients is significantly lower than in the age- and sex-matched general population, with dea...
