简介:AbstractSystemic sclerosis (SSc) is characterized by immune dysfunction, vasculopathy, chronic fibrosis of skin and internal organs with complex etiology. With the rapid development and the application in biomedicine of epigenetics, accumulating evidence has shown that epigenetics plays an important role in the pathogenesis of SSc. Environmental factors via epigenetics are needed to trigger and maintain for the disease in the subjects with genetic predisposition to SSc. The role of epigenetics in the pathogenesis of SSc includes hypermethylation of the promoter region of nitric oxide synthase and bone morphogenetic protein receptors II, up-regulation of histone deacetylases 4 and 5 expression, and down-regulation of miR-193b and miR-152 in endothelial cells inducing vascular dysfunction; DNA hypermethylation and hypoacetylation of histone H3 and H4 in Friend leukemia virus integration 1 and Kruppel-like factor 5 genes, and the abnormal expression of miR-29, miR-129-5p and miR-135b in fibroblasts causing excessive fibrosis; DNA hypomethylation in the promoter regions of CD11a and CD70 genes in CD4+T cells resulting in immune dysfunction. Studies on the role of epigenetics in SSc are of great significance for better understanding the pathogenic machanism of SSc, which is helpful to find new molecular targets for treating SSc, and consequently, improve the prognosis of SSc.

简介:AbstractSystemic lupus erythematosus (SLE) is an autoimmune disease with extreme heterogeneity and potentially involvement of any organ or system. Numerous unanswered questions and challenges in SLE always prompt further exploration. In 2019, great progress in various aspects of SLE emerged. Both the classification criteria and management recommendation for SLE were updated. New promising medications have been widely developed and tested, although subsequent clinical studies are warranted. As an emerging number of most notable studies in SLE were published in both clinical area and basic research in 2019, we aim to summarize the highest quality data on SLE regarding novel insights of pathogenesis, updated recommendations, hot-spot issues on clinical manifestations, new understanding of disease prognosis, and most importantly, the therapeutic advances in SLE in this review.

简介:AbstractIntroduction:Primary systemic amyloidosis is characterized by clonal plasma cell disorder, and its signs and symptoms are various and complex, damage to the skin and mucous membrane is often more likely to attract attention.Here we reported a case of a 61-year-old male patient who presented with topical mucocutaneous lesion, as well unusual skin vegetations.Case presentation:A 61-year-old man was hospitalized due to repeated burning sensation on his back, multiple ecchymosis, and skin vegetations. Through a series of examinations (mainly including skin histopathology, bone marrow cytology, bone marrow flow cytometry, immunofixation electrophoresis), Primary systemic amyloidosis was diagnosed, but multiple myeloma could not be diagnosed. Subsequently, he received chemotherapy. In the half-year follow-up, there was no significant change in his symptoms and signs.Discussion:In this case, in addition to the typical skin damage of primary amyloidosis, the multiple skin vegetations in the buttocks, abdomen, and arms are particularly noteworthy. According to the histopathology and Immunohistochemistry of the skin vegetation, we infer that the formation mechanism of these skin vegetation is lymphatic obstruction caused by amyloid, which leads to lymphatic dilatation, lymph leakage, and dermal edema.Conclusion:Primary systemic amyloidosis is a rare disease, which is often difficult to diagnose. We should be alert to those atypical skin features so as not to delay diagnosis.
