Pharmacotherapy of chronic venous diseases. What do we know about horse chestnut extract? | Bogachev V.Yu., Boldin B.V., Kuznetsov M.R., Rodionov S.V.

The article is devoted to the pharmacotherapy of chronic diseases of the veins of the lower extremities. The effectiveness of horse chestnut extract is considered.

Chronic venous disease (CVD) of the lower extremities is the most common cardiovascular pathology, occurring in more than half of the adult population of industrialized countries. Vein-specific symptoms and syndromes significantly reduce the social activity of patients with CVD and their quality of life. Phlebotropic drugs, along with lifestyle modification and compression therapy, are currently considered as a mandatory component of the complex treatment and rehabilitation of patients with CVD.

Horse chestnut seed extract and pharmacological preparations from it have been successfully used in clinical practice for more than two centuries to treat chronic hemorrhoids, post-traumatic and post-operative edema, as well as CVD of the lower extremities. In the latter case, horse chestnut seed extract showed the best therapeutic results, thanks to which it was included in the line of modern phleboprotectors.

In the Russian Federation, the combined drug Aescusan is registered, which includes a purified extract of horse chestnut seeds and thiamine hydrochloride – vitamin B 1 .

Purified horse chestnut seed extract ( Aesculus hippocastanum ) contains a mixture of pharmacologically active substances: saponins, bioflavonoids, antioxidants and coumarins. Saponins, in particular beta-aescin (syn.: escin), determines the main phleboprotective effect of Aescusan, which is potentiated by bioflavonoids – quercetin, kaempferol and their derivatives. Proanthocyanidin A2 acts as an antihypoxant, and coumarins (esculin, fraxin) have a moderate hypocoagulant effect [1, 2].

Another component that is part of Aescusan is thiamine hydrochloride (vitamin B 1 ). The daily requirement of an adult for thiamine is 1. 5-2 mg, but may vary depending on various factors. It should be noted that thiamine is rapidly destroyed by heating, therefore, when preparing dishes from foods containing vitamin B 1 , most of its beneficial properties are lost. Thiamine plays an important role in carbohydrate, protein and fat metabolism, as well as in the processes of nerve excitation in synapses. In relation to CVD, vitamin B 1 protects cell membranes from the toxic effects of peroxidation products, slows down the aging process, maintains the tone of the smooth muscles of the vascular wall and cardiomyocytes. Vitamin B deficiency 1 is manifested by increased fatigue, weakness and pain in the calf muscles, as well as a tendency to peripheral edema [3].

Due to the combined composition, Aescusan has anti-edematous, anti-inflammatory and phlebotonizing effects, which are realized through various molecular and cellular mechanisms, some of which have already been well studied. In particular, an increase in the tone and contractile activity of the venous wall is associated with an improvement in the selective permeability of slow calcium channels in myocytes, which, as a clinical outcome, is manifested by a decrease in vein-specific symptoms and edema [4].

The additional anti-edematous effect of Aescusan is associated with the stabilization of the vascular wall and the suppression of endothelial dysfunction. The latter occurs as a result of endothelial hypoxia against the background of venous stasis. Endothelial hypoxia is currently considered as one of the key pathogenetic mechanisms for the development and progression of diseases of the cardiovascular system in general and CVD in particular.

Hypoxia of the venous endothelium leads to a deterioration in mitochondrial “respiration” with a decrease in the production of adenosine triphosphate (ATP), a universal energy source for various biochemical processes inside the cell. ATP deficiency reorients intracellular metabolism to the hypoxic pathway, which results in the release of prostaglandins and platelet-activating factor.

In response to chronic hypoxia, the endothelium expresses cell adhesion molecules, leading to the activation of neutrophils and macrophages, which become additional factors for damage to the walls of venous capillaries with increased interstitial edema. The biologically active substances that make up Aescusan prevent the development of intracellular hypoxia, maintain the physiological levels of ATP and phospholipase A2, which is responsible for the release of pro-inflammatory messengers, and also prevent the activation and adhesion of neutrophils, protecting the wall of venous capillaries from leukocyte aggression and normalizing its permeability [5] .

The anti-edematous effect of horse chestnut extract is confirmed by various randomized clinical trials (RCTs). One of them, with the imposition of a pneumatic cuff on the thigh in patients with CVD to further increase venous pressure, demonstrated a decrease in capillary filtration by 22% in patients receiving the drug, while interstitial edema increased in the placebo group [4].

As noted above, the main phleboprotective effect has beta-aescin, which is part of Aescusan, which can suppress the activity of elastase and hyaluronidase. Elastase and hyaluronidase are enzymes actively involved in the destruction of proteoglycans, which are important structural components of the endothelium and extracellular matrix. It has been experimentally proven that aescin shifts the metabolism of proteoglycans towards synthesis and thereby strengthens the capillary wall and prevents extravasation of the liquid part of the plasma [6].

The anti-inflammatory mechanism of horse chestnut seed extract is not well understood. At the same time, its antipyretic and analgesic clinical effect is known. A relatively small amount of experimental data, the most interesting of which are the involution of the inflammatory granuloma and the dose-dependent decrease in the number of leukocytes in the exudate from the trophic ulcer, suggests that Aescusan suppresses the cellular phase of inflammation. This statement confirms the suppression of the synthesis of pro-inflammatory mediators leading to the activation of leukocytes and their transendothelial migration against the background of the use of aescin [7].

In experiments, aescin significantly increased and prolonged the sensitivity of isolated varicose veins, as well as their contractility under the action of norepinephrine. It is important that an increase in the contractile capacity of the venous wall by 10–20% was observed at sufficiently low concentrations of aescin, which can be easily and safely achieved by prescribing preparations based on horse chestnut seed extract per os [8, 9].

As a rule, modern drugs derived from horse chestnut seed extract, including Aescusan, are well tolerated. Previous reports of seed poisoning Aesculus hippocastanum concerned the artisanal production of an extract from them, which included the toxic substance esculoside.

Aescusan, even with long-term use, does not adversely affect reproductive function and fertility in men and women, and does not provoke any adverse effects in offspring.

Indications for use in patients with various forms of CVD and their complications of Aescusan are based on its venotonic, anti-inflammatory, capillary-protective and anti-edematous effects due to a complex, not fully understood molecular and cellular mechanism [10-14].

The main indications for prescribing drugs based on horse chestnut extract, including Aescusan, are complaints associated with CVD, as well as chronic venous edema.

The efficacy of vein-specific symptoms such as pain, itching, sensation of swelling, and edema proper with horse chestnut extract was analyzed in 10 placebo-controlled RCTs included in a Cochrane systematic review.

In 7 RCTs, the main criterion was the dynamics of pain in the calf muscles against the background of CVD. Six of these RCTs demonstrated significant reductions in pain scores in patients treated with horse chestnut extract compared with placebo. Another 1 RCT reported a significant reduction in calf pain from baseline. The NNT score for venous pain was 5.1, with a high level of evidence (grade A). The effectiveness of horse chestnut extract on pruritus was studied in 8 RCTs, 4 of which showed a statistically significant reduction in this highly unpleasant symptom with horse chestnut seed extract compared with placebo (NNT 6.1), and another 2 RCTs showed a statistically significant reduction initial level. The level of evidence is high (class A). Edema was assessed in 6 RCTs. Four studies reported a statistically significant reduction in lower leg swelling in patients treated with horse chestnut seed extract compared with placebo. Another 1 RCT documented a significant reduction in baseline edema. The NNT for horse chestnut seed extract in the treatment of edema in CVD was 4.0, with a high level of evidence (grade A). Measurement of leg volume with a water immersion volumemeter was used in 7 placebo-controlled RCTs on horse chestnut extract. A meta-analysis of 6 of them found a clear advantage of the drug over placebo. The level of evidence is high (class A) [15].

Eight RCTs studied various doses and regimens of preparations based on horse chestnut seed extract, it was shown that taking 100-150 mg of aescin 2 times a day for 2-8 weeks. enough to significantly reduce the volume of the lower leg and the severity of vein-specific symptoms with a casuistically rare frequency of adverse reactions that does not differ from placebo [16–18].

Of great clinical interest are the very ambiguous results of RCT, during which patients with chronic venous edema for 12 weeks. received either horse chestnut extract or compression therapy (stockings class 2 RAL standard) or placebo. Patients assigned to the compression therapy group received a diuretic for 7 days at the stage of selecting compression stockings. The primary endpoint for assessing the effectiveness of treatment options was the logarithmic measure of lower extremity volume measured after 12 weeks. treatment. As a result, the average volume of the legs in the group of patients treated with horse chestnut seed extract and compression therapy decreased by 43. 8±11.4 ml and 46.7±8.2 ml, respectively. In the placebo group, edema increased by 9.8±15.0 ml. Based on the results of this RCT, the authors made the very bold conclusion that the therapeutic efficacy of horse chestnut extract and compression therapy for chronic venous edema is comparable and significantly better than placebo. In continuation of the development of this topic, a proposal was made to prescribe phlebotropic drugs to patients with low adherence to regular wearing of compression stockings [19].

To select the pharmacological regimen for the treatment of CVD, RCTs are relevant, in which a comparative assessment of the horse chestnut seed extract with other widely used phlebotropic drugs is carried out. There are 4 RCTs that compared aescin (50-75 mg 2 times a day) and hydroxyethyl rutoside (HER) in a daily dose of 500 to 2000 mg. Both groups achieved good clinical results without significant statistical differences [20].

Since CVD is 3–4 times more common in women, a gender assessment of the results of phlebotropic therapy becomes clinically important. So, in a double-blind RCT with the inclusion of 137 postmenopausal women divided into 2 groups, 2 regimens for the use of GER 1000 mg / day were compared for the entire treatment period: 1000 mg / day for 4 weeks, then 500 mg / day for another 8 weeks . with the intake of aescin 50 mg 2 r./day. The treatment period was preceded by a 2-week placebo wash-out period followed by a 6-week no-medication follow-up. The diagnosis of CVD and associated edema was confirmed by ultrasound in all patients. The dynamics of the main clinical indicator, edema, was assessed by measuring the volume of displaced water at each visit after 4, 8, and 12 weeks. against the background of ongoing treatment, as well as after 15 and 18 weeks. during the observation period. Horse chestnut extract showed similar efficacy to GER, despite a small, non-significantly larger decrease in volume with the latter. At the same time, patients who received horse chestnut extract noted better dynamics of subjective vein-specific symptoms and drug tolerance [21].

In 1996, a large observational study was conducted in Germany, in which 800 general practitioners took part, evaluating the effect of horse chestnut seed extract on vein-specific symptoms in 5429 patients with various forms of CVD and their complications. The vast majority of patients received the drug at a dose of 75 mg 2 times a day for 4-10 weeks. Positive dynamics in terms of CVD symptoms was noted as early as the 1st week. treatment and gradually increased throughout the period of therapy. Treatment adherence approached 95%, and good or excellent therapeutic efficacy of horse chestnut seed extract was recorded in 94% of patients [22].

The data presented above strongly suggest that CVD-associated symptoms and edema can be effectively controlled with drugs based on horse chestnut extract.

With regard to safety, according to the results of known RCTs, the frequency of unwanted side effects that occur while taking drugs derived from horse chestnut seed extract does not exceed 3% and was comparable to that of placebo. In most cases, undesirable side effects were manifested in the form of dyspepsia, dizziness, headache and pruritus. Isolated cases of severe toxic-allergic reactions have been described [22].

Preparations derived from horse chestnut extract are indicated in current recommendations for the treatment of CVD. In particular, in the guidelines of the American Venous Forum, updated in 2017, aescin, among other phlebotropic drugs, is proposed to be used in addition to compression therapy in the presence of various vein-specific symptoms [23]. In the European clinical guidelines (2018), horse chestnut extract with evidence level A is considered as the drug of choice for pain and edema associated with CVD [24].

In conclusion, it should be noted that modern phlebotropic therapy is an important and integral component of the conservative treatment of CVD and its complications. At the same time, despite the large number of drugs used for this purpose, only some of them have been tested by time and studied in a variety of experimental and clinical studies.
