The correlation between rheumatic diseases and liver diseases is complex and often not given sufficient attention. There are, however, consequences for diagnosis and therapy. Rheumatic diseases can present with hepatic symptoms while liver diseases can exhibit rheumatic symptoms. Examples of liver diseases as a cause of rheumatic symptoms are viral hepatitis B and C, autoimmune hepatitis and hemochromatosis. As a result of rheumatic diseases, such as adult onset Still’s disease and systemic lupus erythematosus, liver dysfunction can occur. Autoimmune hepatitis, primary biliary cirrhosis and primary sclerosing cholangitis are directly associated with rheumatic diseases and have to be distinguished by way of differential diagnosis. During antirheumatic therapy, serious hepatotoxic side effects have to be expected. 相似文献

OBJECTIVES--To investigate the influence of the Th1 and Th2 lymphokines interleukins (IL)-4 and IL-13, interferon gamma (IFN gamma), and several monokines on the adhesion of mononuclear cells to synovial fibroblasts and intercellular adhesion molecule-1 (ICAM-1) expression and cytokine production of synovial fibroblasts in patients with osteoarthritis. METHODS--Synovial fibroblasts were isolated from patients with osteoarthritis and stimulated with IL-1 beta, IL-4, IL-6, IL-10, IL-12, IL-13, tumour necrosis factor alpha (TNF alpha), and IFN gamma. Subsequently, we determined the production of IL-1 alpha, IL-1 beta, IL-6, IL-10, IL-12, IFN alpha and TNF alpha, and the expression of ICAM-1 lymphocyte function associated antigen 3 (LFA-3), BB7, and major histocompatibility complex class II molecules on these cells. Furthermore, the adhesion of freshly isolated mononuclear cells from the peripheral blood was tested using a colourimetric cell-cell adhesion assay. RESULTS--Only production of IL-6 and the expression of ICAM-1 were observed. IL-1 beta and TNF alpha were the most potent stimulatory mediators of both cytokine production and ICAM-1 expression. IL-4 and IL-13 had differential effects as they upregulated cytokine production but downregulated IFN gamma induced ICAM-1 expression. In functional adhesion assays, TNF alpha, IL-1 alpha and, to a lesser extent, IFN gamma led to increased adhesion of mononuclear cells, whereas IL-4 and IL-13 had no effect. CONCLUSIONS--Our data indicate that Th1 and Th2 lymphokines can modulate the function (cytokine production and expression of adhesion molecules) of synovial fibroblasts. 相似文献
