Behcet's disease (BD) is a chronic inflammatory disorder of unknown aetiology, and recognised as a multi-system vasculitis. It has been postulated that an imbalance of the oxidant and antioxidant systems related to the disease are important in its pathogenesis. Previous publications have reported increased levels of enzymatic antioxidant defence systems in patients with BD. The non-enzymatic antioxidant systems, including vitamin C and uric acid, were looked for in the present study. For this aim, the serum malondialdehyde (MDA), an end product of lipid peroxidation, and vitamin C and uric acid, as endogenous antioxidants, were determined in 20 patients with BD (11 in active and 9 in inactive periods) and 20 healthy subjects. The MDA level was significantly higher in both the active and inactive period patients compared with the control group (p < 0.001, p < 0.05, respectively). The MDA level was also significantly higher in the active period patients compared with the inactive period patients (p < 0.05). The vitamin C levels were significantly lower in both the active and inactive period patients compared with the control group (p < 0.001, p < 0.05, respectively). There was no significant difference in the vitamin C level between the active and inactive period patients (p > 0.05). There was also no significant difference in uric acid levels between the groups (p > 0.05). In the patients group, a negative correlation was found between the levels of serum MDA and vitamin C (r=-0.517; p < 0.05). Our results indicate that decreased vitamin C and increased MDA levels reflect the increased levels of oxidative stress in BD patients, and this situation may be important in relation with its pathogenesis.

OBJECTIVE: We aimed to assess the association between cord blood brain-derived neurotrophic factor (BDNF) concentration and maternal depression during pregnancy. METHODS: A total of 48 pregnant women, admitted for elective caesarean section to Department of Obstetrics and Gynecology, The Konya Research and Training Hospital and Konya Necmettin Erbakan University Meram Medical Faculty, were included in this study. The study group included 23 women diagnosed as having depression during pregnancy and the control group included 25 pregnant women who did not experience depression during pregnancy. RESULTS: The groups had similar sociodemographic characteristics. Cord blood BDNF concentration was significantly lower in babies born to mothers with major depression as compared with those in the control group. We didn't find any correlation between the umbilical cord blood BDNF levels and BDI scores. CONCLUSION: The results suggest that the existence of major depression in pregnant women may negatively affect fetal circulating BDNF levels.
