Abstract Background Systemic sclerosis and dermatomyositis are autoimmune connective tissue diseases affecting the skin and various internal organs. Systemic sclerosis is characterized by fibrotic arteriosclerosis of peripheral and visceral vasculature. Objective Analysis of video dermatoscopic picture of systemic sclerosis and dermatomyositis patients and find a characteristic feature for both. Assess serum vascular endothelial growth factor (VEGF) in these patients using enzyme linked immunosorbent assay (ELISA) kits. Perform a statistical analysis of the results to find a relation between video dermatoscopic Picture of systemic sclerosis and dermatomyositis patients and their serum VEGF to help in diagnosis, grading, prognosis and management. Patients and Methods Our case control study included 25 patients with SSc or DM (2555 years) recruited from Ain Shams University Hospitals and 25 apparent healthy controls with matched age and sex. After the study had been approved by Ain shams University of Medical Sciences Research Ethics Committee, all the subjects signed an informed consent before inclusion in the study. Results Serum VEGF level was highly significant in patients than in controls. This may be explained by the excessive release of VEGF in patients due to hypoxia caused by microvascular occlusion that not present in healthy controls. Conclusion Microvascular abnormalities are the earliest features of SSc and DM with elevation of serum VEGF level indicating its role in disease pathogenesis and disturbance of microvessls. Videodermoscopy and measurement of serum VEGF are effective tools in diagnosis, prognosis and grading of autoimmune connective tissue diseases as SSc and DM.

Background: The β-Thalassemia syndromes are the most common hereditary chronic hemolytic anemia due to impaired globin chain synthesis.  Vascular endothelial growth factor (VEGF) plays several roles in angiogenesis which is a crucial process in the pathogenesis of several inflammatory, autoimmune and malignant diseases .Endothelial damage and inflammation make a significant contribution to the pathophysiology of β-thalassemia. Purpose: The aim of the study was to assess serum VEGF level in children with beta-thalassemia major as a marker of angiogenesis. Methods: Blood samples were collected from 40 patients with thalassemia major and 10 healthy controls and assayed for VEGF by enzyme-linked immunosorbent assay. Results: VEGF level was significantly higher in patients with β-Thalassemia major than healthy controls (p=0.001).In addition, VEGF level was higher in splenectomised thalassemic patients than non splenectomised ones (p=0.001) .However, there were a positive correlation between VEGF and chelation starting age (p=0.008) and a negative correlation between VEGF and frequency of blood transfusion (p=0.002). Conclusion: thalassemia patients, especially splenectomized, have elevated serum levels of VEGF. Early chelation and regular blood transfusion help to decrease serum VEGF and the risk of angiogenesis.

Introduction: Since female sexual dysfunction in systemic sclerosis women is multifactorial, we can assume that vascular damage may play a role in pathogenesis. The aim of the study was to evaluate the clitoral blood flow, by Echo color Doppler, and to correlate it whit serum levels of vascular endothelial growth factor and endostatin. Methods: A total of 15 systemic sclerosis women and 10 healthy controls matched for sex and age were enrolled in this study. Serum VEGF165 and endostatin levels were determined in systemic sclerosis patients by commercial enzyme-linked immunosorbent assay kit. Clitoral blood flow was measured by Doppler indices of clitoral artery: pulsatile index, resistive index, and systolic/diastolic ratio were measured. Sexual dysfunction was assessed by Female Sexual Function Index. Results: Vascular endothelial growth factor (pg/mL) and endostatin (ng/mL) median values were significantly higher in systemic sclerosis women than healthy controls. Resistive index and systolic/diastolic ratio median values were significantly higher in systemic sclerosis women than healthy controls. Negative correlation exists between serum levels of vascular endothelial growth factor and resistive index (r = −0.55, p < 0.05). Positive correlation was observed between serum levels of endostatin and resistive index (r = 0.70, p < 0.01) and systolic/diastolic ratio (r = 0.77, p < 0.01). Discussion: We can suppose that clitoral blood flow in systemic sclerosis women is reduced not only for macro- and microvascular damage but also for impaired angiogenesis.

Purpose. To study the change of concentrations of vascular endothelial growth factor (VEGF) in vitreous cavity after vitrectomy in eyes with proliferative diabetic retinopathy (PDR). Methods. In this retrospective study, intravitreal fluid samples were taken at baseline (beginning of the vitrectomy) and postoperatively (several days later after vitrectomy) at the time of prophylactic injection of bevacizumab in forty-eight eyes of forty-eight patients with PDR. Postvitrectomy fluid samples were divided into four groups according to the time interval between the vitrectomy and the injection (group 1, 3–5 days; group 2, 6–10 days; group 3, 11–15 days; group 4, 16–21 days; twelve eyes in each group). Postvitrectomy fluid sample was paired with baseline sample for each eye. VEGF concentrations in the samples were determined by enzyme-linked immunosorbent assay. Recurrent vitreous hemorrhage and neovascular glaucoma within six months postvitrectomy were also analyzed. Results. Overall, the intravitreal VEGF level after vitrectomy (median, 36.95 pg/ml; range, 3.2–1,299.4 pg/ml) was significantly less than the VEGF level at baseline (median, 704.5 pg/ml; range, 30.6–1,981.1 pg/ml). Postoperative and baseline VEGF levels were significantly correlated (r = 0.499, p<0.01). Both the absolute value of postoperative VEGF concentrations and the postop/baseline VEGF ratios declined with time and dramatically decreased in groups 3 and 4. In only two eyes, the postoperative VEGF level was even higher than the baseline VEGF level (postop/baseline VEGF ratio >1), and recurrent vitreous hemorrhage developed within six months in these two eyes. Conclusions. After vitrectomy for PDR, intravitreal VEGF levels decreased substantially in the majority of patients, while persistent high-VEGF level occurred in a few individuals. Postoperative VEGF levels and postop/baseline VEGF ratio declined with time. The postop/preop VEGF ratio may serve as a predictor for late complications.

Airway remodeling describes the structural changes that occur in the asthmatic airway that include airway smooth muscle hyperplasia, increases in vascularity due to angiogenesis, and thickening of the basement membrane. Our aim in this study was to examine the effect of transforming growth factor-β on the release of connective tissue growth factor and vascular endothelial growth factor from human airway smooth muscle cells derived from asthmatic and nonasthmatic patients. In addition we studied the immunohistochemical localization of these cytokines in the extracellular matrix after stimulating bronchial rings with transforming growth factor-β. Connective tissue growth factor and vascular endothelial growth factor were released from both cell types and colocalized in the surrounding extracellular matrix. Prostaglandin E2 inhibited the increase in connective tissue growth factor mRNA but augmented the release of vascular endothelial growth factor. Matrix metalloproteinase-2 decreased the amount of connective tissue growth factor and vascular endothelial growth factor, but not fibronectin deposited in the extracellular matrix. This report provides the first evidence that connective tissue growth factor may anchor vascular endothelial growth factor to the extracellular matrix and that this deposition is decreased by matrix metalloproteinase-2 and prostaglandin E2. This relationship has the potential to contribute to the changes that constitute airway remodeling, therefore providing a novel focus for therapeutic intervention in asthma.

Congenital Lymphoedema

Objective To investigate whether lymphoedema in a Chinese family showed the hereditary and clinical characteristics of Milroy disease, an autosomal dominant form of congenital lymphoedema, typically characterized by chronic lower limb tissue swelling due to abnormal lymphatic vasculature development, and to perform mutational analyses of vascular endothelial growth factor receptor ( VEGFR)3. Methods Individuals from a three-generation family affected by congenital lymphoedema were clinically assessed for Milroy disease. Mutation analysis of VEGFR3 was performed using DNA from family members and healthy controls. Results Out of 20 family members, eight were diagnosed with hereditary lymphoedema. Mutation analyses revealed a novel mutation site for c.3163 G>A, resulting in a p.1055D>N mutation in the second tyrosine kinase domain of VEGFR3, which was present in affected individuals only (absent in all unaffected family members and 130 healthy controls). Computed functional analyses showed the mutation may lead to structural alterations with a probability of 0.99999 of being disease causing. Conclusion A novel mutation associated with Milroy disease was identified in a Chinese family, expanding our knowledge of VEGFR3 gene function and providing a potential molecular target for treating hereditary lymphoedema.

PURPOSE The prognostic value of vascular endothelial growth factor (VEGF) protein, known to stimulate endothelial growth and angiogenesis, was evaluated in node-negative breast carcinoma (NNBC) and compared with established prognostic factors. PATIENTS AND METHODS In 525 consecutive patients with primary invasive NNBC (T1-2N0M0; tumor, node, metastasis stage), of whom 500 patients did not receive any systemic therapy, the cytosolic levels of VEGF165 were measured by using a quantitative enzyme-linked immunosorbent assay. The median follow-up was 46 months. Univariate and multivariate analyses were performed. RESULTS VEGF level was significantly inversely correlated with estrogen receptor (ER) positivity but positively associated with tumor size and histologic grade. Patients with VEGF levels above the median value (2.40 pg/microg of DNA) showed a significantly shorter survival time (P=.0012) than patients with levels less than the median value, also when analyzed as a continuous variable (P=.0277). Tumor size, grade, and ER expression were all statistically significant for overall survival in univariate analyses (P=.0069, P=.014, and P < .001, respectively). Multivariate analysis showed that VEGF level was the strongest predictor of overall survival (P=.0199). Histologic grade was also an independent predictor of survival (P=.0477). Among the 381 patients with ER-positive tumors, a group in general considered to have a good prognosis, we found a significant reduction in survival for those with levels of VEGF greater than the median value (P=.0009). CONCLUSION The results suggest that the level of VEGF165 protein is an independent, strong prognostic factor for survival in patients with NNBC, especially in the subgroup of patients with ER positivity. Thus, cytosolic VEGF165 might be useful to select patients for adjuvant systemic therapy.
