Cardiovascular disease is one of the major causes of mortality in anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV). Metabolic syndrome (MetS) is associated with increased cardiovascular risk in the normal population. However, MetS in AAV has not been adequately investigated. We aimed to determine MetS prevalence and associated factors in AAV patients.
Methods
Thirty-seven AAV patients and 42 healthy controls were enrolled. MetS was determined by International Diabetes Federation (IDF) and National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) criteria. The relationship between clinical features of AAV and MetS was also investigated.
Results
MetS was significantly higher in AAV patients than controls by NCEP-ATPIII (51.4% vs. 26.2%, p 0.022) and IDF (62.2% vs. 35.7%, p 0.020). When AAV patients with MetS were compared to those without, there were significant differences in age, CRP, GFR and NT-pro-BNP. Age [58 (13) vs. 50 (8) years p: 0.028], CRP [4.0 (3.6) vs. 3.2 (1.0) mg/l, p 0.021] and NT-pro-BNP [173.5 (343.7) vs. 106.0 (103.0) pg/ml, p 0.013] were significantly higher in AAV patients with MetS than those without; GFR was significantly lower [38 (46) vs. 83 (51) ml/min/1.73 m2, p 0.004]. ROC curve analysis showed NT-pro-BNP?>?58.0 ng/ml predicted MetS with 87.1% sensitivity and 46.7% specificity (Area under curve: 0.71, CI 0.536–0.902, p 0.041). Multivariate analysis revealed age [OR (95% CI): 1.180 (1.010–1.370), p 0.039] and NT-pro-BNP?>?58 pg/ml [OR (95% CI): 5.5 (1.02–30.1) p 0.047] were independent predictors of MetS in AAV patients.
Conclusion
MetS is significantly higher in AAV patients than controls and is associated with age and NT-pro-BNP. Screening and treating MetS may improve prognosis in AAV patients.
AIM: To evaluate the effects of chronic smoking on color vision in young subjects.
METHODS: This study included 91 smokers and 88 non-smokers (a total of 179 volunteers) without any ophthalmologic and systemical disorders. The subjects were between 18-40 years of age with a best corrected visual acuity (BCVA) of 20/20, normal anterior and posterior segment examinations and normal intraocular pressure. The color vision of the subjects were evaluated with Farnsworth-Munsell 100 Hue test (FMHT). The total error scores and axis calculation were performed for each subject and the results correlated.
RESULTS: Mean age and the standard deviation was 28±5y in the smokers group, and 26.7±5.5y in the control group (P=0.101). Sex distribution was similar in the two groups (P=0.365). There was no significant correlation between age and FMHT total error scores (P=0.069). Median of FMHT total error scores of smokers and non-smokers were 65 and 50.50, respectively. FMHT total error scores was found significantly higher in smokers than non-smokers (P=0.004). There was no statisticaly significant difference between smoker and non-smoker groups with respect to axis ratio calculation (P=0.611). There was no significant correlation with FMHT total error scores with neither smoking duration nor number of cigarettes smoked per day (P=0.405, P=0.454, respectively).
CONCLUSION: This study suggested that chronic smoking affects the color vision of young smokers but this may not be sector selective. 相似文献
AIM: To compare the effects of intravitreal anti-vascular endothelial growth factor (VEGF) and dexamethasone in an experimental rabbit model of posterior penetrating ocular injury.
METHODS: Thirty white New Zealand rabbits were included in the study. A posterior penetrating ocular injury was performed at the superotemporal quadrant. They were randomly divided into three groups. The rabbits in group 1 received intravitreal dexamethasone, in group 2 they received intravitreal bevacizumab and those in group 3 received intravitreal physiological saline solution in both eyes. All eyes were examined ophthalmologically on the 1st, 3rd, 7th, 14th and 28th days following the injury and the clinical findings were scored. On the day 28, the eyes were enucleated, evaluated and scored macroscopically, histopathologically and scanning electron microscopically.
RESULTS: The median clinical score on the 14th and 28th days and the median macroscopic score of the dexamethasone group was significantly better than that of control (P=0.004, 0.018). Dexamethasone group was also better than that of bevacizumab group but the differences did not reach statistical significance. Retinal detachment rate was 8.3%, 16.6% and 12.5% in the dexamethasone group, bevacizumab group and control group, respectively (P=0.476). More extensive fibrocelluler proliferations were observed in controls compared with dexamethasone and bevacizumab groups. But these differences did not reach the statistical significance (P=0.538). In scanning electron microscopy all groups showed fibreous stalk and dense collagen fibrils in vitreous.
CONCLUSION: This study shows that intravitreal injection of both dexamethasone and bevacizumab may reduce the intraocular fibrous proliferation after an experimental posterior penetrating ocular injury in rabbits. 相似文献
To evaluate ovarian reserve in women with familial Mediterranean fever (FMF).
Study design
Thirty women with FMF (20–29 years) and thirty healthy controls (20–29 years) were admitted to this study. Basal serum levels of follicle-stimulating hormone (FSH), oestradiol (E2), luteinizing hormone (LH) and inhibin B were measured on cycle day 3. All participants underwent transvaginal ultrasonographic examination on the third day of their menstrual cycle for the determination of ovarian volume (OV) and total antral follicle count (AFC).
Results
Women with FMF had significantly higher concentrations of FSH, LH and E2 than healthy controls. Total AFC was significantly lower in women with FMF than in healthy controls. OV was also lower in the FMF group but there was no statistically significant difference in OV between the groups. Age was negatively associated with FSH and LH. Inhibin B was found to be negatively correlated with LH and OV.
Conclusions
In this preliminary study, the first in FMF patients, we found that ovarian reserve was reduced in women with FMF compared with healthy controls. FMF may affect the ovarian reserve but the mechanism of this effect is unclear. 相似文献
