Abstract
The present review considers current data on the structure, functions and role of interleukin-13 in the pathogenesis of vascular wall varicose transformation in terms of proteolysis and inflammatory response. It is known that interleukin-13 is able to interact with transforming growth factor-1 in diseases associated with fibrosis. The latter activates fibroblasts and excessive formation of the extracellular matrix, thereby inducing fibrosis of the vascular wall, which is one of the links in the pathogenesis of varicose veins. Also, to date, there is evidence of the interleukin-13 participation in the induction of certain proteolytic enzymes synthesis, such as matrix metalloproteinases. For the latter, participation in the transformation of the venous wall has been proven to date. The remodeling of the venous wall itself can lead to an increase in the expression of proteinases, providing a proteolytic mechanism for changing the structural organization of the venous wall in varicose veins of the lower extremities. At the same time, the involvement of lysosomal cysteine proteinases remains poorly understood. The expression and production of individual cathepsins are regulated by biologically active molecules: interleukin-1, interleukin-6, tumor necrosis factor , which are directly involved in inflammatory reactions in the wall of varicose veins. In particular, venous pathology develops in a vicious circle of inflammation with the formation of abnormal venous blood flow, chronic venous hypertension and dilation, and the recruitment of leukocytes. This leads to a further, deeper, remodeling of the walls and valves of the veins, an increase in blood pressure and the release of pro-inflammatory mediators chemokines and cytokines. In connection with the above, in order to understand the mechanisms of proteolysis in the vascular wall in varicose veins of the lower extremities, it is important to have an idea about the possible interactions of interleukin-13 with transforming growth factor-1, inflammatory cytokines, and cathepsins.

Ann Vasc Surg 2023; 96:365-373. [PMID: 37003361 DOI: 10.1016/j.avsg.2023.03.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 02/28/2023] [Accepted: 03/08/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND Chronic venous insufficiency (CVI) is characterized by progressive inflammatory changes. Inflammatory damage occurs in the veins, adjacent tissues, and can lead to structural changes in the arteries. The aim of this study is to analyze whether the degree of CVI is associated with arterial stiffness. METHODS Cross-sectional study including patients with CVI classified by clinical, etiological, anatomical, and pathophysiological classification (CEAP) 1 to 6. We performed correlation between the degree of CVI, central and peripheral arterial pressure, and arterial stiffness measured by brachial artery oscillometry. RESULTS We evaluated 70 patients, 53 of whom were women with a mean age of 54.7 years. Patients with advanced degrees of venous insufficiency CEAP 4,5,6, had higher levels of systolic, diastolic, central, and peripheral arterial pressures compared to those with early stages (CEAP 1,2,3). The CEAP 4,5,6 group had higher arterial stiffness indices than the CEAP 1,2,3 group: pulse wave velocity (PWV) 9.3 m/s vs. 7.0 m/s, P < 0.001; augmentation pressure (AP) 8.0 mm Hg vs. 6.3 mm Hg; P = 0.04. There was a positive correlation between the degree of venous insufficiency measured by the venous clinical severity score, villalta score and CEAP classification, and the arterial stiffness indices (Spearman's coefficient = 0.62 for PWV and CEAP, P < 0.01). The factors influencing PWV were age, peripheral systolic arterial pressure (SAPp), and AP. CONCLUSIONS There is a correlation between the degree of venous disease and arterial structural changes characterized by arterial pressure and stiffness indices. Degenerative changes secondary to venous insufficiency are associated with impairment of the arterial system, which has implications for the development of cardiovascular disease.

Abstract
The purpose of this study was to identify the inflammatory cytokines that were associated with pachychoroid neovasculopathy (PNV). Seventy-five eyes of 75 patients with PNV, 145 eyes of 145 patients with neovascular age-related macular degeneration without pachyvessels, and 150 eyes of 150 normal subjects were examined for the levels of intraocular cytokines. In eyes with PNV, the levels of IL-1α, IL-1β, IL-2, IL-4, IL-10, and VEGF were significantly higher than that of the controls. Logistic regression analysis showed that the highest association with the pachyvessels was found for IL-4, IL-2, and IL-1α. In eyes with PNV, the levels of IL-4, IL-2, IL-5, IL-13, IL-1α, and IL-1β were significantly higher in eyes with both increased choroidal thickness and choroidal vessel diameter. The strongest correlation with the choroidal thickness and vessel diameter was observed for IL-4. In PNV eyes with polypoidal lesions, the levels of IL-4, IL-17, and TNFβ were significantly correlated with the number of polypoidal lesions. Of these cytokines, IL-4 was especially associated with the thickness of the choroidal vessels and the formation of polypoidal lesions. We conclude that IL-4 is most likely involved in establishing the clinical characteristics of PNV and polypoidal vascular remodeling.

Abstract
BACKGROUND Vein-specific inflammation leads to vascular smooth muscle cells proliferation and extracellular matrix degradation of vein wall. This process is known as remodeling and is promoted by "trapped" leukocytes. Monocyte chemoattractant protein 1 (MCP-1) is a chemokine responsible for trafficking of leukocytes from blood to vein wall. The aim of this study was to measure the MCP-1 concentration in varicose veins blood before and after venoactive drug therapy and to compare it with a concentration of blood from varicose veins of subjects who did not receive drug treatment. METHODS Non-randomized comparative study was conducted on 30 patients with primary varicose veins. 20 patients of the study group received diosmin 900 mg/hesperidin 100 mg once daily. 10 controls received no treatment. MCP-1 level was measured (pg/mL) in the blood from varicose veins twice, at the day of inclusion and after 60 days. Legs discomfort related to chronic venous disease (CVD) symptoms was measured with 10-cm Visual Analogue Scale (VAS) at inclusion and at completion of the study. RESULTS Median (interquartile range, IQR) MCP-1 concentrations in treatment and control groups at inclusion were 171.9 (124.4-216.0) and 157.0 (120.1-163.1), resp., P=0.285. After 60 days of treatment MCP-1 level decreased, but non-significantly to 152.3 (124.1-178.3). In patients who did not receive treatment chemokine level slightly increased to 163.0 (134.0-172.9). Median changes over time were -6.6 (-30.9-7.4) and 10.6 (-3.7-19.2) in the study and control groups, resp. (P=0.048). After 60 days in 12 of 19 and 2 of 9 patients of treatments and control groups MCP-1 decreased (P=0.103). Odds ratio for MCP-1 decreasing was 9.5 (95% CI 1.1-81.5, P=0.043) for those who received venoactive drug. Mean (± standard deviation [SD]) legs discomfort significantly dropped in the study group from 5.7 (±2.5) to 1.9 (±2.2) (P=0.0003), while in controls no changes were registered: 3.4 (±1.3) and 3.5 (± 1.4), resp., P=0.28). Mean difference of VAS at baseline and at follow-up was -3.5 (±2.6) and 0.9 (±2.1), resp. (P<0.0001). CONCLUSIONS Plasma concentration of MCP-1 in varicose veins blood demonstrates a tendency to decrease under two months treatment with a venoactive drug. Future studies are needed to reveal a possible role of MCP-1 as a target considering its role in varicose veins pathogenesis.

Abstract
Venous leg ulcers (VLUs) are the most common type of leg ulcers with a significant socioeconomic burden due to slow healing. Cytokines may be involved in the pathogenesis of VLUs. In this systematic review, our objective was to investigate the association between cytokine levels, including growth factors, with the healing of VLUs. PubMed, Embase, Web of Science and Cochrane Library were searched from their inception to August 2021. We retrieved 28 articles investigating 38 different cytokines in 790 patients. Cytokines were most commonly investigated in wound fluid and less frequently in biopsies and serum. The studies were judged as having a moderate to high risk of bias, and the results were often inconsistent and sometimes conflicting. A meta-analysis was not performed due to clinical and methodological heterogeneities. We found weak evidence for elevated IL-1α, IL-6, IL-8, TNF-α and VEGF levels in non-healing VLUs, an elevation that declined with healing. TGF-β1 levels tended to increase with VLU healing. Other cytokines warranting further investigations include EGF, FGF-2, GM-CSF, IL-1β, IL-1Ra and PDGF-AA/PDGF-BB. We conclude that non-healing VLUs may be associated with an elevation of a palette of pro-inflammatory cytokines, possibly reflecting activated innate immunity in these wounds. There is a paucity of reliable longitudinal studies monitoring the dynamic changes in cytokine levels during wound healing.

Abstract
OBJECTIVES The study evaluates the potential morphological changes that may occur in the venous wall in the case of the patients with chronic venous disease which associates treatment with statins for at least 2 years. METHODS Operated patients with chronic venous disease in the CEAP C2-C3 stage were included in the study. 215 venous fragments, collected from 50 patients within the study group and 179 venous fragments collected from 52 patients within the control group were microscopically analysed, evaluating a series of morpho-anatomical parameters. RESULTS In the study group, it was found that, venous reflux predominantly affects small veins, and also, a significant increase in collagen deposits in the adventitia and media tunics, proportional to the thickening of the venous wall. CONCLUSION Our results indicate possible effects of statins upon the venous morphology. Further studies are needed to determine the impact of these results on daily practice.

Abstract
Despite its increased application in pancreatic ductal adenocarcinoma (PDAC), complete response to neoadjuvant therapy (NAT) is rare. Given the critical role of host immunity in regulating cancer, we sought to correlate baseline inflammatory profiles to significant response to NAT. PDAC patients receiving NAT were classified as responders (R) or nonresponders (NR) by carbohydrate antigen 19-9 response, pathologic tumor size, and lymph node status in the resected specimen. Baseline (treatment-naive) plasma was analyzed to determine levels of 27 inflammatory mediators. Logistic regression was used to correlate individual mediators with response. Network analysis and Pearson correlation maps were derived to determine baseline inflammatory mediator profiles. Forty patients (20R and 20NR) met study criteria. The R showed significantly higher overall survival (59.4 vs. 21.25 mo, P=0.002) and disease-free survival (50.97 vs. 10.60 mo, P=0.005), compared with NR. soluble interleukin-2 receptor alpha was a significant predictor of no response to NAT (P=0.045). Analysis of inflammatory profiles using the Pearson heat map analysis followed by network analysis depicted increased inflammatory network complexity in NR compared with R (1.69 vs. 1), signifying a more robust baseline inflammatory status of NR. A panel of inflammatory mediators identified by logistic regression and Fischer score analysis was used to create a potential decision tree to predict NAT response. We demonstrate that baseline inflammatory profiles are associated with response to NAT in PDAC, and that an upregulated inflammatory status is associated with a poor response to NAT. Further analysis into the role of inflammatory mediators as predictors of chemotherapy response is warranted.

Abstract
Objective: Growing evidence indicates that depressive disorders (DDs) are an important risk factor for atherosclerosis. The aim of this study was to evaluate the presence of common carotid artery (CCA) intima-media thickness (IMT) and circulation inflammation markers in patients with DD. Methods: A cross-sectional prospective study was undertaken comparing 40 patients with DD to 40 individuals free of depression, matched for age and gender. The Beck Depression Inventory questionnaire, serum total cholesterol, triglycerides, high-sensitivity C-reactive protein, interleukin-6, tumor necrosis factor α, P-selectin, and E-selectin levels were measured. The CCA-IMT was assessed with duplex sonography. Results: Patients with DD were more likely to smoke (65% vs 40%; P = .03) and have higher levels of serum total cholesterol (211 mg/dL vs 181 mg/dL; P = .010), triglycerides (138 mg/dL vs 97 mg/dL; P = .005), and P-selectin (0.87 ng/mL vs 0.61 ng/mL; P = .05) and lower levels of interleukin 6 (4.4 ± 2.1 pg/mL vs 10.3 ± 1.1 pg/mL; P = .002). The CCA-IMT was similar in both groups (0.07 ± 0.02 cm vs 0.06 ± 0.01 cm; P = .31). Among those with CCA-IMT in the upper quartile, subjects in the DD group had lower levels of interleukin 6 ( P = .05) and triglycerides ( P = .01) and higher levels of soluble P-selectin ( P = .03). Conclusion: Patients with DD do not present with higher CCA-IMT than a control group, although smoking and a higher level of serum lipids are present. Inflammatory biomarkers seem to be higher in patients with DD.

Chemokines and Growth Factors Produced by Lymphocytes in the Incompetent Great Saphenous Vein. Mediators Inflamm 2019; 2019:7057303.

Abstract
The role of cytokines in the pathogenesis of chronic venous disease (CVD) remains obscure. It has been postulated that oscillatory flow present in incompetent veins causes proinflammatory changes. Our earlier study confirmed this hypothesis. This study is aimed at assessing chemokines and growth factors (GFs) released by lymphocytes in patients with great saphenous vein (GSV) incompetence. In 34 patients exhibiting reflux in GSV, blood was derived from the cubital vein and from the incompetent saphenofemoral junction. In 12 healthy controls, blood was derived from the cubital vein. Lymphocyte culture with and without stimulation by phytohemagglutinin (PHA) was performed. Eotaxin, interleukin 8 (IL-8), macrophage inflammatory protein 1 A and 1B (MIP-1A and MIP-1B), interferon gamma-induced protein (IP-10), monocyte chemoattractant protein-1 (MCP-1), interleukin 5 (IL-5), fibroblast growth factor (FGF), granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), platelet-derived growth factor-BB (PDGF-BB), and vascular endothelial growth factor (VEGF) were assessed in culture supernatants by a Bio-Plex assay. Higher concentrations of eotaxin and G-CSF were revealed in the incompetent GSV, compared with the concentrations in the patients' upper limbs. The concentrations of MIP-1A and MIP-1B were higher in the CVD group while the concentration of VEGF was lower. In the stimulated cultures, the concentration of G-CSF proved higher in the incompetent GSV, as compared with the patients' upper limbs. Between the groups, the concentration of eotaxin was higher in the CVD group, while the IL-5 and MCP-1 concentrations were lower. IL-8, IP-10, FGF, GM-CSF, and PDGF-BB did not reveal any significant differences in concentrations between the samples. These observations suggest that the concentrations of chemokines and GFs are different in the blood of CVD patients. The oscillatory flow present in incompetent veins may play a role in these changes. However, the role of cytokines in CVD requires further study.
