Cím:	Reduced flow-mediated vasodilation as a marker for cardiovascular complications in lupus patients / Kiss E., Soltesz P., Der H., Kocsis Z., Tarr T., Bhattoa H., Shoenfeld Y., Szegedi G.
Dátum:	2006
Megjegyzések:	Systemic lupus erythematosus is associated with accelerated atherosclerosis and increased cardiovascular morbidity and mortality. Objectives were to determine endothelial dysfunction with a non-invasive method in lupus patients and to analyse correlation with risk factors and atherosclerotic complications. Sixty-one SLE patients and 26 healthy age- and sex-matched control subjects were entered into the study. The diameters of brachial artery at rest, during reactive hyperaemia, and after glyceril trinitrate administration, as well as the intima-media thickness of the common carotid artery were measured using high-resolution B-mode ultrasonography. Demographic characteristics, lipid profile, paraoxonase activity, concentration of anti-phospholipid antibodies and anti-oxLDL were assessed together with atherosclerotic complications. The endothelium dependent vasodilation (FMD) was significantly impaired in SLE patients as compared to controls. The absolute difference of vessel diameter (Deltad) was 0.25+/-0.15 mm vs. 0.38+/-0.16 mm (p=0.001), and Deltad as in percent of the rest diameter was 7.31+/-5.2% vs. 9.86+/-3.87% (p=0.013) in lupus patients and controls, respectively. Nitrate mediated dilation (NMD) did not differ. FMD negatively correlated with age, systolic and diastolic blood pressure in SLE, but did not show significant correlation with the other examined parameters. However, FMD significantly differed between SLE patients with (5.54+/-4.36%) and without (8.81+/-5.28%) cardiovascular complications (p=0.01). The determination of flow-mediated vasodilation is a useful method to detect endothelial dysfunction in lupus patients, as reduced capacity of brachial artery may distinguish between SLE patients and healthy subjects, as well as lupus patients with and without atherosclerotic vascular complications.

Cím:	Tumor-associated antigens in systemic sclerosis and systemic lupus erythematosus : associations with organ manifestations, immunolaboratory markers and disease activity indices / Éva Szekanecz, Gabriella Szűcs, Zoltán Szekanecz, Tünde Tarr, Péter Antal-Szalmás, Szilvia Szamosi, János Szántó, Emese Kiss
Dátum:	2008
Megjegyzések:	Some tumor-associated antigens (TAAs) are expressed on inflammatory cells. We previously detected increased production of CA15-3, CA19-9 and CA125 in rheumatoid arthritis (RA). The production of some TAAs may also be increased in patients with systemic sclerosis (SSc), systemic lupus erythematosus (SLE) and other connective tissue diseases. Some of these TAAs contain sialylated carbohydrate motifs and they are involved in tumor-associated cell adhesion and metastasis. OBJECTIVES: We assessed levels of TAAs in the sera of SSc, SLE patients, patients with infectious diseases and healthy subjects. Serum TAA levels were correlated with each other, as well as with disease activity markers and organ involvement. METHODS: TAAs including CEA, CA15-3, CA72-4, CA125 and CA19-9 were assessed by immunoassay in the sera of 92 patients with SSc, 40 patients with SLE, 50 age- and sex-matched healthy controls, as well as with 40 patients with current bacterial or viral infections. Normal upper limits for these TAAs were 3.4 mg/l, 25 kU/l, 6.9 kU/l, 35 kU/l and 34 kU/l, respectively. RESULTS: There were significantly more SSc patients showing abnormally high levels of CA19-9 (8.8% vs 2.0%), CA125 (11.0% vs 6.0%) and CA15-3 (28.4% vs 14.0%) in comparison to controls (p < 0.05). In SLE, significantly more patients had elevated levels of CEA (32.5% vs 20.0%), CA19-9 (7.5% vs 2.0%), CA125 (15.0% vs 6.0%) and CA72-4 (15.0% vs 8.0%) than did controls (p < 0.05). The mean absolute serum levels of CEA (6.6+/-1.7 vs 1.8+/-1.4 mg/l) and CA15-3 (22.9 +/- 1.8 vs 18.6 +/- 2.2 kU/l) were also significantly higher in SSc compared to controls (p < 0.05). We found numerous correlations between the serum levels of different TAAs within the SSc and SLE population. Among SSc patients, serum CEA (R = 0.290; p = 0.005), CA15-3 (R = 0.260; p = 0.020) and CA19-9 (R = 0.257; p = 0.013) correlated with renal involvement. Serum CA15-3 also correlated with joint involvement (R = 0.329; p = 0.003), ANA positivity (R = 0.288; p = 0.010) and CRP levels (R = 0.407; p < 0.001). Within the SLE population, serum CA72-4 correlated with central nervous involvement (R = 0.624; p = 0.004) and CA125 correlated with the SLEDAI composite activity index (R = 0.666; p = 0.002). Patients with infections exerted serum TAA patterns similar to healthy controls. CONCLUSION: The concentration of some TAAs may be elevated in the sera of patients with SSc or SLE in comparison to healthy subjects. Pathogenically, most of these TAAs contain carbohydrate motifs and thus they may be involved in inflammation-associated adhesive events. Furthermore, the production of some TAAs may correlate with organ involvement or disease activity in scleroderma or lupus.
