Cím:	Malignancies and soluble tumor antigens in rheumatic diseases / Szekanecz E., András C., Sándor Z., Antal-Szalmás P., Szántó J., Tamási L., Kiss E., Szekanecz Z.
Dátum:	2006

Megjegyzések:	Paraneoplastic symptoms, caused by a malignancy, but not directly related to invasion by the tumor or its metastases are the result of a wide variety of tumor-derived biologic mediators like hormones, peptides, antibodies, cytotoxic lymphocytes, autocrine and paracrine mediators. Recognition of paraneoplastic syndromes is important, as it may lead to an early diagnosis of cancer. There is some evidence that systemic inflammatory diseases, such as rheumatoid arthritis (RA), lupus, scleroderma or dermatomyositis may increase the risk for the development of malignancies, predominantly lymphoproliferative disorders. However, reports are somewhat controversial. Immunosuppressive and cytotoxic drugs used in antirheumatic therapy, such as methotrexate, cyclophosphamide, azathioprine or anti-TNF biologicals may also lead to the development of such tumors. Tumor-associated antigens may be produced by inflammatory cells and their production may be increased in RA and other autoimmune diseases.

Cím:	Increased production of the soluble tumor-associated antigens CA19-9, CA125, and CA15-3 in rheumatoid arthritis : potential adhesion molecules in synovial inflammation? / Szekanecz E., Sándor Z., Antal-Szalmás P., Soós L., Lakos G., Besenyei T., Szentpétery A., Simkovics E., Szántó J., Kiss E., Koch A.

Megjegyzések:	Some tumor-associated antigens (TAAs) are expressed on inflammatory cells. We previously detected carcinoembryonic antigen (CEA; CD66) in the rheumatoid (RA) synovium. The production of CEA, CA19-9, CA125, and CA15.3, may be increased in patients with RA, scleroderma, lupus, and Sjogren's syndrome (SS). Some of these TAAs contain sialylated carbohydrate motifs and they are involved in tumor-associated cell adhesion and metastasis. We assessed levels of TAAs in the sera of RA patients and healthy subjects. Serum TAA levels were correlated with disease markers including serum rheumatoid factor (RF), C-reactive protein (CRP), and anti-CCP antibody levels, DAS28, age disease duration. TAAs including CEA, CA15-3, CA72-4, CA125, and CA19-9, and neuron-specific enolase (NSE) were assessed by immunoassay in the sera of 75 patients with RA and 50 age- and sex-matched healthy controls. Normal upper limits for these TAAs were 3.4 microg/L, 25 kU/L, 6.9 kU/L, 35 kU/L, 34 kU/L, and 16.3 microg/L, respectively. There were significantly more RA patients showing abnormally high levels of CA125 (10.8% versus 7.1%), CA19-9 (8.1% versus 0%), and CA15-3 (17.6% versus 14.3%) in comparison to controls (P < 0.05). The mean absolute serum levels of CA125 (23.9 +/- 1.8 versus 16.8 +/- 2.2 kU/L) and CA19-9 (14.2 +/- 1.2 versus 10.5 +/- 1.6 kU/L) were also significantly higher in RA compared to controls (P < 0.05). Among RA patients, serum CEA showed significant correlation with RF (r = 0.270; P < 0.05). None of the assessed TAAs showed any correlation with CRP, anti-CCP, DAS28, age or disease duration. The concentration of some TAAs may be elevated in the sera of patients with established RA in comparison to healthy subjects. CEA, CA19-9, CA125, and CA15-3 contain carbohydrate motifs and thus they may be involved in synovitis-associated adhesive events. Furthermore, some TAAs, such as CEA, may also correlate with prognostic factors, such as serum RF levels.
