Assessment of semaphorin 3A and semaphorin 7A levels in primary Sjogren's syndrome.
Sjogren's syndrome (SS) is a chronic autoimmune connective tissue disease. Varying rates of system involvements may be seen in the course of the disease. Semaphorins has multifunctions in several physiological and pathological processes such as immune system regulation. The association of Semaphorin 3A (Sema3A) and Semaphorin 7A (Sema7A), which are immune semaphorins, with autoimmune diseases is interesting for researchers. We aimed to compare serum Sema3A and Sema7A levels between primary SS and control subjects, and investigated Sema3A and Sema7A levels in disease subgroups and associated system involvements. 50 consecutive primary SS patients and 40 healthy subjects followed in the Rheumatology clinic of Cumhuriyet University Medical Faculty between 2017 and 2018 were included in the study. Inclusion criteria of patients were diagnosis of primary SS according to the 2016 ACR/EULAR classification criteria. Serum Sema3A and Sema7A levels were measured by commercial ELISA kit. Both groups were similar in terms of age, gender, and body mass index. Serum Sema3A and Sema7A levels were significantly lower in SS than in the controls (p = 0.001 and p = 0.005, respectively). Serum Sema3A levels were significantly lower in patients with renal involvement than in patients without (p = 0.03). Sema3A and Sema7A may play a role in the etiopathogenesis of SS and may be a potential serological marker for the diagnosis of SS and may be a target for treatment.Emre Urhan, Ayse Camci Urhan, Halef Okan Dogan, Ali Sahin

Urinary semaphorin 3A as an early biomarker to predict contrast-induced acute kidney injury in patients undergoing percutaneous coronary intervention.
Contrast-induced acute kidney injury (CI-AKI) is a serious complication of diagnostic coronary angiograph and percutaneous coronary intervention (PCI). However, the exact pathophysiological mechanisms underlying CI-AKI development are largely unknown. The present study examined whether urinary semaphorin 3A levels predict the development of CI-AKI in patients undergoing PCI. This study enrolled 168 patients with stable angina undergoing elective PCI. Serial urine samples, obtained at baseline and 2, 6, 12, 24, 36, and 48 h post-PCI were analyzed by semaphorin 3A and neutrophil gelatinase-associated lipocalin (NGAL) ELISA kit. AKI was defined as an increase in serum creatinine beyond 50% according to the RIFLE classification system. Receiver operator characteristic (ROC) curve analyses identified optimal semaphorin 3A and NGAL values for diagnosing CI-AKI. CI-AKI occurred in 20 of 168 patients. There were no significant differences in the baseline clinical characteristics and angiographic findings between non-AKI patients group and AKI patients group. Both urinary semaphorin 3A and NGAL levels significantly increased at 2 and 6 h post-PCI. ROC analysis showed that the cut-off value of 389.5 pg/mg semaphorin 3A at 2 h post-PCI corresponds to 94% sensitivity and 75% specificity and the cut-off value of 94.4 ng/mg NGAL at 2 h post-PCI corresponds to 74% sensitivity and 82% specificity. Logistic regression showed that semaphorin 3A levels at 2 and 6 h post-PCI were the significant predictors of AKI in our cohort. Urinary semaphorin 3A may be a promising early biomarker for predicting CI-AKI in patients undergoing PCI.Li Ning, Zhiguo Li, Dianjun Wei, Haiyan Chen, Chao Yang, Dawei Wu, Yanchun Wang, Jingwei Zhang

Inhibition of pathological retinal neovascularization by semaphorin 3A.
Pathological retinal angiogenesis is a major cause of vision loss. Semaphorin 3A (Sema3A), a chemorepellent guidance protein, plays crucial roles in neural and vascular patterning. To identify its role in retinal neovascularization, we investigated its antiangiogenic effects.Wenzhen Yu, Yujing Bai, Na Han, Fei Wang, Min Zhao, Lvzhen Huang, Xiaoxin Li
