Pitesa R, Yuen WYR, Hill AG. Flavonoids and post haemorrhoidectomy recovery: a systematic review and meta-analysis. ANZ J Surg 2024; 94:1480-1490. [PMID: 38847122 DOI: 10.1111/ans.19116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 05/14/2024] [Accepted: 05/27/2024] [Indexed: 09/25/2024]
Abstract
BACKGROUND Haemorrhoidectomy is the gold standard for definitive treatment of high-grade symptomatic haemorrhoids but is often associated with substantial pain. This systematic review aims to explore the potential of flavonoids in alleviating the postoperative symptom burden following excisional haemorrhoidectomy. METHODS A systematic review of the literature was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO CRD42023472711). Randomized controlled trials (RCTs) published PubMed, MEDLINE, Embase, and Scopus from inception to 1st December 2023 were retrieved. The primary outcome investigated was post-operative pain. Meta-analysis was performed using Review Manager version 5.4.1. RESULTS Ten articles with 775 patients were included. The meta-analysis identified statistically significant decreases in post-operative pain in favour of the flavonoid groups (Standardized Mean Difference -0.66 [95% confidence intervals (CI) -0.82, -0.52]; P < 0.00001), and bleeding (Odds Ratio 0.13 [95% CI 0.09, 0.19]; P < 0.00001). CONCLUSION Flavonoids show promise as a means of reducing pain associated with excisional haemorrhoidectomy. Further research is required to investigate topical routes of administration and standardize regimes.

Abstract
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous adverse reaction which exhibits a diverse range of presentations. We described a 48-year-old man diagnosed with acute generalized exanthematous pustulosis (AGEP)-like DRESS following the administration of diosmin and hesperidin. To our knowledge, diosmin and hesperidin-induced DRESS are exceptionally rare. This aims to raise awareness of potential severe cutaneous side effects in patients taking these agents.

Abstract
Pulmonary embolus (PE) carries a significant impending morbidity and mortality, especially in intermediate and high-risk patients, and the choice of initial anticoagulation that allows for therapeutic adjustment or manipulation is important. The preferred choice of anticoagulation management includes direct oral anticoagulants. Vitamin K antagonists and low-molecular-weight heparin are preferred in special populations or selected patients such as breastfeeding mothers, those with end-stage renal disease, or obese patients, among others. This article reviews the primary and longer-term considerations for anticoagulation management in patients with PE and highlights special patient populations and risk factor considerations.

Abstract
Peripheral venous hypertension has emerged as a prominent characteristic of venous disease (VD). This disease causes lower limb edema due to impaired blood transport in the veins. The phlebotonic drugs in use showed moderate evidence for reducing edema slightly in the lower legs and little or no difference in the quality of life. To enhance the probability of favorable experimental results, a virtual screening procedure was employed to identify molecules with potential therapeutic activity in VD. Compounds obtained from multiple databases, namely AC Discovery, NuBBE, BIOFACQUIM, and InflamNat, were compared with reference compounds. The examination of structural similarity, targets, and signaling pathways in venous diseases allows for the identification of compounds with potential usefulness in VD. The computational tools employed were rcdk and chemminer from R-Studio and Cytoscape. An extended fingerprint analysis allowed us to obtain 1846 from 41,655 compounds compiled. Only 229 compounds showed pharmacological targets in the PubChem server, of which 84 molecules interacted with the VD network. Because of their descriptors and multi-target capacity, only 18 molecules of 84 were identified as potential candidates for experimental evaluation. We opted to evaluate the berberine compound because of its affordability, and extensive literature support. The experiment showed the proposed activity in an acute venous hypertension model.

Abstract
INTRODUCTION VEIN STEP was conducted to collect international data on the management of chronic venous disease (CVD) and to assess the effectiveness of conservative treatments for the relief of CVD signs and symptoms. METHODS This international, observational, prospective, longitudinal, cohort study recruited adult outpatients consulting for symptomatic CVD. The primary objective was the effectiveness of conservative treatments on symptoms, signs and quality of life in a real-life setting assessed using a range of patient-reported outcome measures: 10-cm Visual Analog and Patient Global Impression of Change scales for symptoms; Venous Clinical Severity Score for physician assessment of signs; and 14-item ChronIc Venous Insufficiency Questionnaire (CIVIQ-14) for quality of life. At inclusion, patients were prescribed conservative treatment according to the physicians' usual practice. Follow-up visits took place at weeks 2 and 4, with an optional week 8 visit. RESULTS The analysis set comprised 6084 subjects (78% female) from nine countries with a mean age of 50.6 ± 13.8 years and BMI of 28.0 ± 4.9 kg/m2. The most common CEAP classifications were C1 (23.0%), C2 (31.6%), and C3 (30.7%). Conservative therapy consisted of oral venoactive drugs (VADs; 95.8% of subjects) including micronized purified flavonoid fraction (MPFF 75.5%) and diosmin (18.8%), compression (52.0%), and topicals (31.5%). Conservative therapy led to global symptom improvement in 89% of patients after 2 weeks and 96% at 4 weeks. Pain, leg heaviness, cramps, and sensation of swelling were improved in 82%, 71%, 45.5%, and 46% of patients, respectively. Conservative therapy was associated with a decrease over time in patient-assessed global symptom intensity: - 2.37 ± 1.73 (P < 0.001) and physician-assessed disease severity - 1.83 ± 2.82 (P < 0.001). Among the VADs, MPFF-based conservative therapy was associated with the greatest reduction in symptom and sign intensity. Improvements in CIVIQ-14 were observed with all treatments but were greatest for MPFF. CONCLUSION In this prospective study conducted in the real-world setting, treatment with conservative therapy, in particular MPFF, was associated with meaningful improvements in the clinical signs and symptoms of disease as well as in quality of life in patients with CVD. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT04574375.

Abstract
Diosmin is used to relieve chronic venous disease (CVD) symptoms. This study aimed to investigate the anti-inflammatory and antioxidant effects of diosmetin-3-O-β-d-glucuronide, the major metabolite of diosmin, using human skin explants. The explants were exposed to substance P (inflammation model) or UVB irradiation (oxidative model) and to five diosmetin-3-O-β-d-glucuronide concentrations. Inflammation was evaluated through interleukin-8 (IL-8) secretion measurements and capillary dilation observation, and oxidation was evaluated by measuring the hydrogen peroxide levels and observing cyclobutane pyrimidine dimers (CPDs). In substance-P-exposed explants, diosmetin-3-O-β-d-glucuronide induced a significant decrease in IL-8 secretions, with a maximal effect at 2700 pg/mL (-49.6%), and it reduced the proportion of dilated capillaries and the mean luminal cross-sectional area (p < 0.0001 at all tested concentrations), indicating a vasoconstrictive effect. In UVB-irradiated fragments, diosmetin-3-O-β-d-glucuronide induced a significant decrease in hydrogen peroxide production and in the number of CPD-positive cells, reaching a maximal effect at the concentration of 2700 pg/mL (-48.6% and -52.0%, respectively). Diosmetin-3-O-β-d-glucuronide induced anti-inflammatory and antioxidant responses, with the maximal effect being reached at 2700 pg/mL and corresponding to the peak plasma concentration estimated after the oral intake of 600 mg of diosmin, the daily dose usually recommended for the treatment of CVD. These ex vivo findings suggest a protective role of diosmetin-3-O-β-d-glucuronide against inflammatory and oxidative stress affecting the vascular system in CVD pathophysiology.

Abstract
Pelvic venous insufficiency (PVI) is frequently associated with symptoms of abdominal pain or discomfort that is overlooked or under-diagnosed in women. Despite the fact that pelvic venous insufficiency in men is very well documented, its occurrence in women needs to be further studied. Patients with pelvic varicose veins undergo a long and inconclusive diagnostic work-up before the exact cause of the symptoms is identified. Gonadal venous insufficiency (GVI) is a condition that can present acutely, leading to diagnostic challenges. We present a case report of a 47-year-old female with acute abdominal pain and GVI, where endovascular embolization was used for successful treatment. The patient was diagnosed with GVI based on imaging findings of an enlarged left ovarian vein with retrograde flow and dilated pelvic veins seen on magnetic resonance imaging (MRI) with contrast material. Due to the severity of her symptoms and imaging findings, endovascular embolization was chosen as the treatment modality. The embolization was successful, and the patient's symptoms resolved completely. This case highlights the challenge of diagnosing GVI with acute clinical expression and the potential benefits of endovascular embolization as a treatment option. Further studies are needed to determine the optimal management strategies for acute GVI, but endovascular embolization should be considered a safe and effective option. At the same time, we present a short review of the recent literature data related to this topic.

Abstract
Purpose Venoactive drugs are widely used to improve the symptoms and signs of chronic venous disease. This study aimed to analyze the rate of adverse events after venoactive drug prescription and subsequent compliance and switching rates. Methods Using the National Health Insurance Service database, individuals with at least one chronic venous disease code between January 2009 and December 2019 were identified, and 30% (2,216,780 individuals) of these were sampled. Finally, 1,551,212 patients were included, and we analyzed adverse events, compliance, and switching rates with 8 venoactive drugs, including Vitis vinifera extract, naftazone, micronized purified flavonoid fraction, Vitis vinifera leaf extract, diosmin, diobsilate calcium, bilberry fruit dried extract, and sulodexide. Results The most commonly prescribed venoactive drug was Vitis vinifera extract (72.2%), followed by sulodexide (9.3%), and Vitis vinifera leaf dry extract (8.2%). Adverse event rates were significantly lower in the naftazone and diosmin groups (P = 0.001 and P = 0.002, respectively) and significantly higher in the Vitis vinifera leaf dry extract group (P = 0.009). Drug adherence to sulodexide was the highest throughout the study period, followed by billberry extract and dobesilate (all P < 0.001). For most drugs, the drug switching rate was low (<5.0%). Conclusion Vitis vinifera extract was the most commonly prescribed venoactive drug in Korea, and drug adherence to sulodexide was the highest among all venoactive drugs. The adverse event rates were significantly lower in the naftazone and diosmin groups.

Abstract
Inflammation is the primary response to infection and injury. Its beneficial effect is an immediate resolution of the pathophysiological event. However, sustained production of inflammatory mediators such as reactive oxygen species and cytokines may cause alterations in DNA integrity and lead to malignant cell transformation and cancer. More attention has recently been paid to pyroptosis, which is an inflammatory necrosis that activates inflammasomes and the secretion of cytokines. Taking into consideration that phenolic compounds are widely available in diet and medicinal plants, their role in the prevention and support of the treatment of chronic diseases is apparent. Recently, much attention has been paid to explaining the significance of isolated compounds in the molecular pathways related to inflammation. Therefore, this review aimed to screen reports concerning the molecular mode of action assigned to phenolic compounds. The most representative compounds from the classes of flavonoids, tannins, phenolic acids, and phenolic glycosides were selected for this review. Our attention was focused mainly on nuclear factor-κB (NF-κB), nuclear factor erythroid 2-related factor 2 (Nrf2), and mitogen-activated protein kinase (MAPK) signaling pathways. Literature searching was performed using Scopus, PubMed, and Medline databases. In conclusion, based on the available literature, phenolic compounds regulate NF-κB, Nrf2, and MAPK signaling, which supports their potential role in chronic inflammatory disorders, including osteoarthritis, neurodegenerative diseases, cardiovascular, and pulmonary disorders.

Abstract
The World Health Organization declared monkeypox a global public health emergency on 23 July 2022. This disease was caused by the monkeypox virus (MPXV), which was first identified in 1958 in Denmark. The MPXV is a member of the Poxviridae family, the Chordopoxvirinae subfamily, and the genus Orthopoxvirus, which share high similarities with the vaccinia virus (the virus used to produce the smallpox vaccine). For the initial stage of infection, the MPXV needs to attach to the human cell surface glycosaminoglycan (GAG) adhesion molecules using its E8 protein. However, up until now, neither a structure for the MPXV E8 protein nor a specific cure for the MPXV exists. This study aimed to search for small molecules that inhibit the MPXV E8 protein, using computational approaches. In this study, a high-quality three-dimensional structure of the MPXV E8 protein was retrieved by homology modeling using the AlphaFold deep learning server. Subsequent molecular docking and molecular dynamics simulations (MDs) for a cumulative duration of 2.1 microseconds revealed that ZINC003977803 (Diosmin) and ZINC008215434 (Flavin adenine dinucleotide-FAD) could be potential inhibitors against the E8 protein with the MM/GBSA binding free energies of −38.19 ± 9.69 and −35.59 ± 7.65 kcal·mol−1, respectively.

Abstract
Because of their medicinal characteristics, effectiveness, and importance, plant-derived flavonoids have been a possible subject of research for many years, particularly in the last decade. Plants contain a huge number of flavonoids, and Diosmin, a flavone glycoside, is one of them. Numerous in-vitro and in-vivo studies have validated Diosmin's extensive range of biological capabilities which present antioxidative, antihyperglycemic, anti-inflammatory, antimutagenic, and antiulcer properties. We have presented this review work because of the greater biological properties and influences of Diosmin. We have provided a brief overview of Diosmin, its pharmacology, major biological properties, such as anti-cancer, anti-diabetic, antibacterial, anticardiovascular, liver protection, and neuroprotection, therapeutic approach, potential Diosmin targets, and pathways that are known to be associated with it.
