Background: The prevalence of anti-Neutrophil Cytoplasmic Antibodies (ANCAs) and anti-Cardiolipin Antibodies (anti-CL Ab) in Behcet’s Disease (BD) and also their roles in vascular involvement is controversial. Objective: To assess the prevalence of ANCAs and anti-CL Ab as well as their correlations with clinical manifestations in Iranian patients with BD. Methods: In this case/control study, the sera from 88 patients with BD and 88 healthy controls were evaluated. The levels of ANCAs and anti-CL Ab were measured using indirect ELISA method. Results: The levels of anti-CL, anti-PR3 and anti-MPO (Myeloperoxidase) IgG autoantibodies between BD patients and healthy controls were not statistically different (p=0.21, p=0.28 and p=0.74, respectively). In addition, there were no significant deferences between BD patients with and without vascular involvement in the levels of anti-CL (1.42 ± 1.24 GPLU/ml and 1.58 ± 1.18 GPLU/ml, respectively; p=0.71), anti-PR3 (0.0 ± 0.0 U/ml and 0.08 ± 0.27 U/ml, respectively; p=0.10) and anti MPO (0.48 ± 0.23 U/ml and 0.52 ± 0.22 U/ml, respectively; p=0.41) IgG autoantibodies. Nevertheless, mean titer of anti-CL IgG was higher in male patients with skin rash than those without skin rash (2.2 ± 0.88 GPLU/ml and 1.11 ± 1.22 GPLU/ml, respectively; p=0.017). Conclusion: While anti-CL, anti- PR3 and anti-MPO IgG autoantibodies do not play a major role in susceptibility to BD or pathogenesis of vascular involvement in our patients, anti-CL Ab might be involved in skin lesion development in Iranian male BD patients. However, the results should be confirmed in other studies.

Background: The clinical significance of antiphospholipid antibodies in patients with chronic hepatitis C virus (HCV) and some other viral infections is controversial. Objective: To study the prevalence of anticardiolipin antibody (ACLA) and antibeta2glycoproteinI antibody (antibeta2GPI antibody) in HCV and hepatitis B virus (HBV) infected patients and its association with liver clinical parameters. Methods: Serum levels of ACLA, antibeta2GPI antibody as well as platelet count, ALT (alanine transaminase), PT (prothrombine time), disease duration and liver histologic findings of 38 patients with HBV and 15 patients with HCV infections were compared with those of 58 healthy controls. Results: Serum titres of ACLA in HCV and HBV patients (13.4 ±7.1 GPL units/ml), and in each of the HCV (15.18±9.91 GPL units/ml) and HBV (12.7 ± 5.7 GPL units/ml) patients were significantly higher than that of the control group (3.4±2.3GPL units/ml). However, there was no significant difference in serum levels of antibeta2GPI antibody from patients with HCV and HBV (3.3 ± 1.3 GPL units/ml) or HCV alone (2.79 ± 1.01 GPL units/ml) or HBV alone (3.4±1.3GPL units/ml) and that of the control group (3.3±1.1GPL units/ml). Conclusion: The findings suggest that the presence of ACLA has no pathologic significance in patients with HBV and HCV infections.
