[Varicosis-Current treatment concepts]

Varicosis is a chronic progressive disease characterized by varicose veins of the lower extremities. Pain, swelling and heaviness of the legs are typical symptoms. These symptoms are caused by a pathological venous reflux, arising from a weakness of the vein wall and progressive venous insufficiency. The indications for invasive surgery are the symptomatic clinical, etiological, anatomical, pathophysiological (CEAP) stages C2s-C6. Compression therapy and venoactive drugs can be recommended for conservative therapy. When it comes to surgical treatment conventional open vein surgery is associated with the best long-term results. Endovenous thermal ablation is associated with few postoperative complications and favors earlier mobilization of the patient. Sclerotherapy has become established with good clinical results for the ablation of reticular and telangiectatic veins, for recurrences and complicated vein anatomy.

The 2023 Society for Vascular Surgery, American Venous Forum, and American Vein and Lymphatic Society clinical practice guidelines for the management of varicose veins of the lower extremities. Part II: Endorsed by the Society of Interventional Radiology and the Society for Vascular Medicine

The Society for Vascular Surgery, the American Venous Forum, and the American Vein and Lymphatic Society recently published Part I of the 2022 clinical practice guidelines on varicose veins. Recommendations were based on the latest scientific evidence researched following an independent systematic review and meta-analysis of five critical issues affecting the management of patients with lower extremity varicose veins, using the patients, interventions, comparators, and outcome system to answer critical questions. Part I discussed the role of duplex ultrasound scanning in the evaluation of varicose veins and treatment of superficial truncal reflux. Part II focuses on evidence supporting the prevention and management of varicose vein patients with compression, on treatment with drugs and nutritional supplements, on evaluation and treatment of varicose tributaries, on superficial venous aneurysms, and on the management of complications of varicose veins and their treatment. All guidelines were based on systematic reviews, and they were graded according to the level of evidence and the strength of recommendations, using the GRADE method. All ungraded Consensus Statements were supported by an extensive literature review and the unanimous agreement of an expert, multidisciplinary panel. Ungraded Good Practice Statements are recommendations that are supported only by indirect evidence. The topic, however, is usually noncontroversial and agreed upon by most stakeholders. The Implementation Remarks contain technical information that supports the implementation of specific recommendations. This comprehensive document includes a list of all recommendations (Parts I-II), ungraded consensus statements, implementation remarks, and best practice statements to aid practitioners with appropriate, up-to-date management of patients with lower extremity varicose veins.

Improving venous symptoms in C0s-C1s patients after multicomponent diosmin-based preparation: Initial experience

The use of drug therapies in patients with chronic venous disease (CVD) remains a topic of debate regarding safety, compliance, and effectiveness. Although the beneficial effects of molecules like diosmin have been established in patients with chronic venous insufficiency (CVI) of C3-C6 classes, the evidence for its use in C0-C1 patients is not well documented. This report aims to describe and analyze the positive impact of a new diosmin-based drug therapy on a population of C0-C1 patients in terms of relief of venous symptoms.

Micronized Purified Flavonoid Fraction in Hemorrhoid Disease: A Systematic Review and Meta-Analysis

Introduction

Hemorrhoidal disease (HD) is a common and recurrent problem for many adults worldwide. Venoactive drugs, such as micronized purified flavonoid fraction (MPFF; Daflon^®), have been used to treat HD and their clinical benefits have been demonstrated in previous meta-analyses of clinical trials. The aim of this study was to evaluate the efficacy of MPFF across the broader spectrum of signs and symptoms following treatment of patients with HD.

Methods

We performed a systematic review of the literature to identify randomized clinical trials in which MPFF treatment was compared to placebo or no treatment for acute HD or for relief of symptoms after patients had undergone medical management or a surgical procedure to remove hemorrhoids. The main endpoints investigated were bleeding, pain, pruritus, discharge or leakage, and overall improvement. There was no limit on treatment duration.

Results

From 351 unique records retrieved, 11 studies reported in 13 articles were included. On the basis of findings from qualitative analysis, MPFF was reported in most studies to be beneficial in treating bleeding, pain, pruritus, anal discharge/leakage, and tenesmus, and in overall improvement. Quantitative meta-analysis of four studies indicated that MPFF treatment provided significant benefits for bleeding (odds ratio [OR] 0.082, 95% confidence interval [CI] 0.027–0.250; P < 0.001), discharge/leakage (OR 0.12, 95% CI 0.04–0.42; P < 0.001), and overall improvement according to patients (OR 5.25, 95% CI 2.58–10.68; P < 0.001) and investigators (OR 5.51, 95% CI 2.76–11.0; P < 0.001). MPFF also tended to decrease pain (OR 0.11, 95% CI 0.01–1.11; P = 0.06).

Conclusion

Taken together, these results suggest that MPFF treatment can improve the most important signs and symptoms of HD.

Early Stages of Chronic Venous Disease: Medical Treatment Alone or in Addition to Endovenous Treatments

Chronic venous disease (CVD) is one of the most prevalent diseases worldwide. The health condition of most patients with early stage CVD will worsen over time, and this progression increases the burden as well as the costs of treatment and reduces patient quality of life (QoL). This highlights the importance and the likely cost-effectiveness of treatment of patients with early stage CVD. Options for managing the early stages of CVD include lifestyle changes together with venoactive drugs (VAD); VADs may be used alone or in conjunction with interventional treatment of varices such as sclerotherapy, surgery, or endovenous treatments. Micronized purified flavonoid fraction (MPFF; Daflon^®) is a well-studied VAD which has anti-inflammatory activities, reduces endothelial activation and leukocyte adhesion, and increases capillary resistance and integrity, to eventually improve venous tone, CVD symptoms and QoL. This article is based on previously conducted studies and does not contain any studies with human participants or animals performed by the author.

The Benefits of Micronized Purified Flavonoid Fraction (MPFF) Throughout the Progression of Chronic Venous Disease

At the 2019 European Venous Forum in Zurich Switzerland, a symposium entitled "State of the art: benefits of MPFF throughout CVD progression" was held to discuss the developing treatment strategies for patients at all stages of chronic venous disease (CVD). At the early stages of CVD, management should be focused on preventing disease progression through lifestyle changes and conservative treatment; treatment can also include venoactive drugs (VAD) such as micronized purified flavonoid fraction (MPFF; Daflon®), which is the most well-known and most widely prescribed VAD in Europe. As the disease progresses, patients who require interventional procedures (e.g., endovenous procedure or sclerotherapy) can also benefit from MPFF treatment in the recovery period after the procedure, as MPFF has been shown to reduce periprocedural pain and bleeding (hematoma), and to improve CVD symptoms during this period. Management of CVD in patients with venous leg ulcers (VLU) is the most challenging; in these patients, recommended adjunct therapies to be combined with standard compression therapy include VAD (MPFF) and non-VAD drugs (pentoxifylline and sulodexide) which have been shown to speed VLU healing in comparison with compression therapy alone.

The Most Severe Stage of Chronic Venous Disease: An Update on the Management of Patients with Venous Leg Ulcers

Venous leg ulcers (VLUs) are the most severe manifestation of chronic venous disease (CVD). Due to their chronic nature, high recurrence rate and slow healing time, VLUs account for 80% of all leg ulcers seen in patients with CVD. VLUs impose a heavy burden on patients that reduces their quality of life; VLUs also represent a major socioeconomic impact due to the cost and duration of care. The primary medical approach to treating VLUs is local compression therapy in combination with venoactive drug (VAD) pharmacotherapy to promote the reduction of the inflammatory reaction initiated by venous hypertension. Micronized purified flavonoid fraction (MPFF; Daflon^®) is the most widely prescribed VAD. MPFF counteracts the pathophysiologic mechanisms of CVD and ulceration and has proven to be an effective adjunct to compression therapy in patients with large and chronic VLUs. Two other non-VAD drugs, pentoxifylline and sulodexide, have also been shown to improve VLU healing and are also recommended in addition to compression therapy. However, MPFF is the only VAD with the highest strength of recommendations in the 2018 guidelines for the healing of VLUs.

Micronized Purified Flavonoid Fraction (MPFF) for Patients Suffering from Chronic Venous Disease: A Review of New Evidence

Chronic venous disease (CVD) is both prevalent and unavoidable in many people as a result of persistent or unalterable risk factors, the most important of which are advanced age, excess body weight, and family history. Given this inevitability, medical treatment is required to alleviate symptoms and slow disease progression. Venoactive drug therapy is emerging as a valuable treatment option for many CVD patients and micronized purified flavonoid fraction (MPFF) is the most widely prescribed and well-studied venoactive drug available. Recent evidence from animal models of venous hypertension and from clinical trials, as well as from systematic reviews, shows that MPFF is effective at alleviating many of the most common symptoms of CVD including leg pain, leg heaviness, sensations of swelling, cramps, and functional discomfort. In addition, MPFF improves the clinical signs of redness, skin changes, and edema, and improves quality of life. Collectively, these findings support the strong recommendation for MPFF treatment found in the 2018 international guidelines for the management of CVD.Funding: Servier.

Burden and Suffering in Chronic Venous Disease

Chronic venous disease (CVD) is widespread, underdiagnosed, and can progress to chronic venous insufficiency and venous ulcers, which can require extensive treatment and hospitalization. These conditions negatively impact patient quality of life and place substantial burdens on healthcare resources. The two main risk factors for CVD are age and obesity. Thus, with the growing prevalence of obesity and the increasing longevity of the population, the burden of CVD is expected to increase dramatically in the coming decades. Appropriate lifestyle changes and care, which may include treatment with venoactive drugs, can slow disease progression, improve quality of life, and are likely to reduce healthcare costs. Physicians should be aware of this growing problem and of the effective treatments available for CVD. We recommend the accompanying short summaries from a symposium held at the recent European Venous Forum as a means for our colleagues to learn more about the burden and suffering associated with CVD.

The Seriousness of Chronic Venous Disease: A Review of Real-World Evidence

Chronic venous disease (CVD) is a prevalent condition that tends to worsen with age. Patients initially seek treatment to relieve symptoms of leg pain, discomfort, heaviness and swelling, all of which impact their quality of life. As the disease increases in severity to include varicose veins, skin changes, and venous ulcer, the demand for treatment increases while the quality of life further diminishes. The prevalence of CVD is highest in Western countries where it already consumes up to 2% of healthcare budgets. With the aging of the global population, the prevalences of CVD and severe CVD are projected to increase substantially, foretelling unsustainably large increases in the healthcare resources and costs needed to treat CVD patients in the coming decades. Effective venoactive drug treatments and ablation procedures are available that provide symptom relief, improve quality of life, slow disease progression, and promote ulcer healing. In addition, venoactive drug treatments may be highly cost-effective. However, there is evidence that physician awareness of CVD is suboptimal and that many patients with CVD are not being treated or referred to specialists according to established guidelines. To decrease this treatment gap and prevent unnecessary disease progression, international guidelines are available to help physicians consider CVD treatment options and refer patients when warranted. Improved disease awareness and appropriate early treatment may help reduce the coming burden of CVD.Funding: Servier.
