Serum angiostatin levels in patients with Behçet's disease: does angiogenesis play a role in the pathogenesis of Behçet's disease?

Angiogenesis plays an important role in the pathogenesis of inflammatory diseases, but the possible role of angiogenesis in Behçet's disease (BD) has not yet been studied. The aim of this study was to determine angiostatin levels in patients with BD and the role of angiogenesis in the pathogenesis of the disease. Thirty-seven patients with BD (mean age: 28·6±5·4 years, mean disease duration: 9·3±3·7 years) and 18 healthy controls were enrolled to the study. Twenty-four patients were in active and 13 patients were in inactive stage of the disease. The mean serum angiostatin level of patients with BD was 113·9±53·2 and 60·7±20·1 ng/ml in healthy controls. The mean serum angiostatin level was 142·7±43·1 ng/ml in active and 86·9±15·5 ng/ml in inactive patients with BD. Serum angiostatin levels were significantly high in patients with BD compared with healthy controls (P<0·001) and it was significantly high in active patients compared with inactive patients with BD (P<0·001). In inactive patients with BD, serum angiostatin concentrations were found to be higher compared with healthy controls (P<0·01). In active BD patients, the mean serum angiostatin level was correlated with the deep vein thrombosis (r = 0·482, P = 0·05), uveitis (r = 0·582, P = 0·01), and arthritis (r = 0·492, P = 0·05). According to these results; elevated serum angiostatin levels in patients with BD suggest the possible role of angiogenesis in the pathogenesis of the disease and its high levels in inactive Behçet's patients is related with the continuous activation of the disease even in the subclinical period.

Prevalence of the metabolic syndrome in a Turkish adult population.

AIM: The aim of the present study was to determine the prevalence of the metabolic syndrome using Adult Treatment Panel III (ATP III) criteria in Adana, a southern province of Turkey. METHODS: The randomly selected study population included 1637 adults who were 20-79 yr of age. The presence of > or = 3 of components like hypertension (defined as blood pressure > or = 130/> or = 85 mmHg on two separate examinations, or usage of antihypertensive agents), visceral obesity (waist circumference >88 cm in females and >102 cm in men), low HDL cholesterol level (<1.04 mmol/l in men and <1.29 mmol/l in females), high triglyceride level (a fasting triglyceride level > or = 1.7 mmol/l), fasting glucose level > or = 6.1 mmol/l, or usage of antihyperglycaemic drugs, indicated the metabolic syndrome. RESULTS: The prevalence of the metabolic syndrome was 33.4% and more common in women than in men (39.1 vs 23.7%; p<0.0001). Both women and men with the metabolic syndrome were older than subjects without. In men, frequencies of the metabolic syndrome in urban and rural areas were similar (23.1 vs 24.3%; p>0.05), but were markedly higher among women in rural than urban areas (44.5 vs 31.2%; p<0.0001). CONCLUSIONS: Developing countries like Turkey also need to start action to prevent and treat the components of the metabolic syndrome. Prevention of the modifiable risk factors, such as obesity and physical inactivity, and blood pressure control should be the key strategy for avoiding mortality and financial costs of the healthcare system, especially in view of limited resources.
