Hematological malignancies in connective tissue diseases.

Hematological malignancies in connective tissue diseases. Lupus. 2020 Jan 14;:961203319899986 Authors: Noureldine HA, Nour-Eldine W, Hodroj MH, Noureldine MHA, Taher A, Uthman I Abstract Chronic inflammation has profound tumor-promoting effects. Inflammatory cells are the key players in immunosurveillance against tumors, and immunosuppression is known to increase the risk of tumors. Autoimmune diseases, which manifest as loss of self-tolerance and chronic immune dysregulation, provide a perfect environment for tumor development. Aside from managing the direct inflammatory consequences of autoimmune pathogenesis, cancer risk profiles should be considered as a part of a patient's treatment. In this review, we describe the various associations of malignancies with autoimmune diseases, specifically systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, and Sjögren's syndrome, as well as discuss the mechanisms contributing to the pathogenesis of both disorders.

te; N Abstract The management of patients undergoing immunosuppressive agents is really challenging. Based on precaution principle, it seems mandatory to stop immunosuppressive (or immunomodulating) agents during radiation. Yet, it is impossible in grafted patients. It is possible in patients with autoimmune disease, but in this case, the autoimmune disease might modify patient's radio-sensitivity. We provide a short review about the safety of radiotherapy in grafted/auto-immune patients. The literature is limited with data coming from outdated case-report or case-control studies. It seems that radiotherapy is fea...

In this study, we analyzed the metabolic profiling of fecal samples from SLE patients and healthy controls based on ultra-high-performance liquid chromatography equipped with mass spectrometry for exploring the potential biomarkers of SLE. The results showed that 23 differential metabolites and 5 perturbed pathways were identified between the two groups, including aminoacyl-tRNA biosynthesis, thiamine metabolism, nitrogen metabolism, tryptophan metabolism, and cyanoamino acid metabolism. In addition, logistic regression and ROC analysis were used to establish a diagnostic model for distinguishing SLE patients from healthy ...

Conclusions The clinical trials discussed here, which include several trials investigating novel therapeutic targets, demonstrate that translational research in pemphigus and pemphigoid is a fast-growing field. We thus expect that several novel treatments will be shortly available for the treatment of pemphigus and pemphigoid patients. Given the high, and thus far unmet, medical need in this field (110), this is highly encouraging and will hopefully improve the quality of life of the affected patients. In addition to the compounds and targets described here, several new targets have been recently identified in preclinical...

Conclusion: Our data indicate reduced P2X7R expression and function in SLE patients compared with HC and, conversely, increased IL-6 signaling. The possible consequences of reduced P2X7R, mainly on cytokines network deregulation and lymphocyte proliferation, will be further investigated as well as the role of IL-6 as a possible therapeutic target especially in lupus serositis. Introduction With the first reports of Burnstock in 1970s, adenosine triphosphate (ATP) has passed from a simple molecule devoted to energy reserve, to a relevant extracellular signaling molecule able to mediate numerous physiological and pat...

Conclusions In recent years, there have been many advances in the understanding of the molecular basis for vascular involvement in APS, but many areas need to be further investigated, in particular the association between altered genetic/epigenetic profiles, autoantibodies and clinical manifestations, and the effectiveness of new therapeutic strategies. It would be interesting to apply next generation sequencing technologies like RNA-Seq along with GWAS to screen both, the gene profile and the whole transcriptome of large cohorts of primary APS patients, in order to reveal the mutations/polymorphisms, post-transcriptiona...

Abstract Comprehensive identification of antigens in immune complexes (IC-antigens) is beneficial to provide insights into pathophysiology and could form the basis for novel diagnostic and treatment strategies for many immune-related diseases. Immune complexome analysis is a method for comprehensively identifying and profiling IC-antigens in biological fluids (such as serum and cerebrospinal fluid). We applied this strategy to the analysis of circulating ICs in autoimmune diseases (rheumatoid arthritis, Sjögren's syndrome, systemic scleroderma, and systemic lupus erythematosus), infectious diseases, and cance...

Rationale: Aromatase inhibitors (AIs) are a class of drugs widely used in the treatment of estrogen sensitive breast and ovarian cancer which convert testosterone to estradiol and androstenedione to estrogen. The AIs of third generation, including anastrazole, letrozole and exemestane, have actually become the standard of care of estrogen-receptor-positive breast cancer in menopausal women and are recommended as adjuvant treatment after surgery in place of/or following tamoxifen. Their main side-effects include reduction in bone mineral density, occurrence of menopausal manifestations and development of musculoskeletal s...

Systemic sclerosis (SSc) is an immune-mediated autoimmune disease characterized by fibrosis and vascular abnormalities. The cellular and molecular mechanisms remain unclear, and current therapies are limited. Cell metabolism has been shown to play an essential role in cancer survival and tumour invasion as well as in rheumatic diseases such as systemic lupus erythematosus, rheumatoid arthritis and osteoarthritis. Although little is known about SSc, cell metabolism may provide new clues for understanding its pathogenesis.
