Abstract:

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.

ANTI CARDIOLIPIN ANTIBODIES IN PATIENTS WITH ISCHEMIC EVENTS

To determine the presence of anticardiolipin (aCL) antibodies in patients with ischemic events, we designed a case-control study. We studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. Plasma samples were assessed for IgG anticardiolipin antibodies by enzyme-linked immunosorbent assay (ELI...

Atypical, cytoplasmic and perinuclear anti-neutrophil cytoplasmic antibodies in patients with inflammatory bowel disease.

Atypical, cytoplasmic and perinuclear anti-neutrophil cytoplasmic antibodies (x-, c- and pANCA, respectively) are associated with a variety of inflammatory diseases, including inflammatory bowel disease (IBD). Anti-neutrophil cytoplasmic antibodies are more common in patients with ulcerative colitis (UC) than in patients with Crohn's disease (CD). Most publications only refer to p- and cANCA in...

[Anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitides].

The anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitides are a group of uncommon diseases characterised by inflammatory cell infiltration and necrosis of blood vessel walls. ANCA there has been considerable progress towards understanding their pathogenesis. This results in endothelial activation with increased transmigration and adherence of neutrophils to vessel walls. Specific ...
