Aim: The aim of this pilot, single-blinded study was to evaluate the efficacy of a proprietary, dietary supplement Lady Prelox® for supporting and improving sexual function in generally healthy, post-menopausal women., Methods: The Lady Prelox® and placebo control groups were comparable at inclusion with regard to the total Female Sexual Function Index (FSFI) score, as well as for the six individual FSFI domains, with 40 women (50.1 ± 3.1 years) and 43 women (51.2 ± 2.3 years), respectively., Results: At baseline the women in the verum group presented with a mean total FSFI score of 44.6 ± 24.1 which increased significantly already after four weeks treatment with Lady Prelox® to 70.9 ± 18.5 and further increased to 71.7 ± 23.9 after completion of the eight-week trial period. In the control group the mean total FSFI was 44.1 ± 22.8 at inclusion and non-significantly increased to 45 ± 21.4 after four weeks and 47.4 ± 21.8 after eight weeks, respectively. The treatment with Lady Prelox® was comparatively significantly more effective than placebo after both four and eight weeks of treatment (P<0.05). The individual six FSFI domains related to desire, arousal, lubrication, orgasm, satisfaction and pain did all respond favourably to treatment with Lady Prelox®; however, with only marginable higher scores in the placebo group. Four women in each group dropped out because of inabilities to attend scheduled check-ups. No adverse effects were reported., Conclusion: This study opens an interesting perspective for women experiencing moderate sexual function impairment and suggests a promising new treatment option. Further studies with larger numbers of women, including also premenopausal and perimenopausal women are warranted.

The aim of this study was to evaluate the efficacy of colostrum (ARD Colostrum) in association with the immunomodulator Bifivir in the prevention of flu episodes compared with anti-flu vaccination. The registry groups included no prevention, vaccination, vaccination+immunomodulators, and immunomodulators only. Groups were comparable for age and sex distribution. In the group without prevention there were 8 major episodes and 12 minor episodes out of 34 subjects (8-12/34); in the vaccination group the respective figures were 8-13/38; in the group treated with a combination of vaccination and immunomodulators (ARD Colostrum + Bifivir) the figures were 4-9/33; and in the group treated with immunomodulators only there were 11 viral episodes (3-8) in 36 subjects. The episodes in the vaccination+immunomodulators and immunomodulators only groups were significantly lower compared with the other two groups (P<0.05). The number of episodes registered with the immunnomodulators was significantly lower than those observed in patients using vaccination or no prevention (P<0.05). The number of days of disease was higher in untreated controls compared to the groups treated with immunomodulators (P<0.05) and 2 times higher in the vaccination group compared to the same groups (P<0.05). The average relative costs were significantly lower (2.3 times) in the immunomodulators groups in comparison with the other groups (P<0.05). No problems concerning tolerability or side effects were observed during the study. Compliance was very good. In conclusion, the administration of immunomodulators is very cost effective and appears to be more effective than vaccination to prevent flu.

The aim of this study was to evaluate the clinical efficacy of standardized French maritime pine bark extract Pycnogenol in patients with severe chronic venous insufficiency (CVI). 98 subjects with symptomatic CVI and edema were randomly assigned to one group treated with 150 mg Pycnogenol a day only, another group with stockings only and a third group with both Pycnogenol and elastic stockings. The average ambulatory venous pressure (AVP) at inclusion was 58+/-7 mm Hg (range 48-60 mm Hg) with a refilling time (RT)<12 s (average 7+/-2 s). The duration of the disease was on average 6.0+/-3.1 years. There were no differences in AVP or RT among the 3 groups at inclusion and microcirculatory and clinical evaluations were comparable. After 8 weeks treatment there was a significant decrease of rate of ankle swelling, resting flux, transcutaneous pO(2) and clinical symptom scores in all groups with significantly better results for the combination treatment. Pycnogenol alone was more effective than compression alone for all parameters (p<0.05). No side-effects were observed; compliance and tolerability were very good. This study corroborates a significant clinical role for Pycnogenol in the management, treatment and control of CVI also in combination with compression., (Copyright 2010 Elsevier GmbH.

Patients (with venous or arterial disease) are particularly affected by even minor sprains as edema, swelling are more disabling and cause a more severe clinical picture. In such vulnerable population, it is imperative to rehabilitate the patient in shortest possible time to regain the functionality of the injured joint and thus assure ambulation. The aim of the present study was to compare the efficacy of locally applied and orally administered ketoprofen in a group of 41 patients with vascular diseases of lower limbs with accidental grade I ankle sprain. Forty one patients were included in this study and divided into in three treatment groups: ketoprofen 10% spray gel* (360 mg/die), oral ketoprofen (tablets, 25 mg t.i.d. and control group (no pharmacological treatment). The duration of treatment was one week. The three groups of patients were comparable for age and sex distribution and for the clinical characteristics at inclusion. After seven days of treatment all patients experienced reduction of symptoms (pain at rest and on active movement, swelling) which was significant only in patients treated by topical, local application of ketoprofen. The effects of oral treatment were not significantly different from those observed in untreated controls. The minimal effort treadmill testing showed significant increase in pain-free walking distance in patients who applied the medication locally in comparison to the other groups. The tolerability of locally applied ketoprofen was good and no side effects were noted. The observed clinical outcomes of the patients included in this small, pilot study indicated that locally applied ketoprofen 10% spray gel is effective in relieving the pain and other symptoms of ankle sprain in vascular patients.

Ankle sprains mainly caused by accidents or strenuous sport activities can often be quite painful and impair motility. If not treated immediately and correctly, sprains may lead to severe complications. The aim of the present study was to compare the efficacy and safety of topically applied ketoprofen versus orally administered ketoprofen in 20 patients with grade I ankle sprain and 34 patients with grade II sprain. The patients were divide into in two treatment groups and received either topically applied ketoprofen treatment (ketoprofen 10% spray-gel; Prontoflex; 360 mg/die) or orally administered ketoprofen treatment (ketoprofen tablets; 3x50 mg/die). Treatment duration was one week. After 3 and 7 days of treatment, reduction of spontaneous pain and pain on active movement in the Prontoflex group was significantly bigger greater in the oral treatment group, irrespective of sprain severity. Regarding secondary parameters as mobility impairment and ankle swelling topically applied ketoprofen treatment turned out to be significantly superior to orally administered ketoprofen treatment. Additionally, Prontoflex was well tolerated, whereas ketoprofen tablets caused gastrointestinal side effects in some patients. The good efficacy in pain reduction and absence of side effects in the present study distinguished the topically applied ketoprofen as a favorable treatment for patients with accidental or sport soft tissue injuries.

The aim of this independent study was to demonstrate the rapidity of the efficacy of an oral venotropic compound (Linfavenix, including natural elements) in patients with chronic venous insufficiency (CVI). Two groups of patients with chronic venous insufficiency (CVI) ankle swelling) were treated with Linfavenix or with below-knee elastic compression. The average ambulatory venous pressure (AVP) at inclusion (both groups)was 56.2 (range 48-55) with a refilling time (RT) shorter than 10 seconds. These parameters indicated a severe level of venous hypertension. There were no significant differences in AVP and RT between the two groups. The two groups of subjects with CVI were comparable; in the Linfavenix group there were 14 patients (age 44.5; sd 4; range 34-55; 7 females); in the elastic compression group there were 12 patients (45.4;5; range 36-56; 7 females). The clinical picture and microcirculatory parameters at inclusion were comparable. RF was comparable at inclusion in the two groups. At two weeks, the differences in RF (between goups) were not significant (the flux decreased in both groups, indicating improvement) while at 4 weeks the difference was larger (but non significant between the two groups) with a significant decrease in RF in the Linfavenix group. The RAS was also comparable at inclusion. Both groups had a significant decrease at 2 and 4 weeks. The decrease produced by Linfavenix after 4 weeks in RF was larger and significant (p<0.05) in comparison with the elastic compression group. Also the differences observed in ASLS were significant in both groups with an important, significant difference in favour of Linfavenix at 4 weeks (op<0.05) visibile as edema reduction. The decrease in edema was relevant in both groups at 2 (p<0.05) and 4 weeks (p<0.05) with a minimal but significant difference (p<0.05) between the Linfavenix and the elastic compression group. These variations in microcirculatory parameters indicate that the treatment with Linfavenix is, in its microcirculatory efficacy, at least comparable than elastic compression with is considered a standard therapeutic option in these patients. A significant level of improvement was reached with Linfavenix, in most patients (10/14) at 2 weeks for RF, at 7 days for the RAS and also at 2 weeks in almost all patients (13/14) considering ASLS and edema. No side effects due to treatment were observed. Compliance and tolerability were very good (no patient had to stop treatment; there were no drop-outs). In conclusion venous microangiopathy and edema were improved by the treatment with Linfavenix (better in comparison with compression) in a few days.

The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of 100 mg Pycnogenol daily (oral capsules) in a 3 month study in patients with osteoarthritis (OA). OA symptoms were evaluated by WOMAC scores, mobility by recording their walking performance (treadmill). Treatment (77 patients) and placebo group (79) were comparable for age, sex distribution, WOMAC scores, walking distances and use of antiinflammatory drugs. The global WOMAC score decreased by 56% (p < 0.05) in the treatment group versus 9.6% in the placebo group. Walking distance in the treadmill test was prolonged from 68 m at the start to 198 m after 3 months treatment (p < 0.05), under placebo, from 65 m to 88 m (NS). The use of drugs decreased by 58% in the treatment group (p < 0.05) versus 1% under placebo. Gastrointestinal complications decreased by 63% in the treatment group, but only 3% under placebo. Overall, treatment costs were reduced significantly compared with placebo. Foot edema was present in 76% of the patients of the treatment group at inclusion and in 79% of the controls. After 3 months edema decreased in 79% of Pycnogenol patients (p < 0.05) vs 1% in controls. In conclusion, Pycnogenol offers an option for reduction of treatment costs and side effects by sparing antiinflammatory drugs., ((c) 2008 John Wiley & Sons, Ltd.)

In a previous, double-blind, placebo-controlled study we evaluated the efficacy of a 3-month treatment with Pycnogenol for 156 patients with osteoarthritis of the knee. Pycnogenol significantly decreased joint pain and improved joint function as evaluated using the WOMAC score and walking performance of patients on a treadmill. In this study, we further investigated the anti-inflammatory and antioxidant activity of Pycnogenol in a subset of the osteoarthritis patients presenting with elevated C-reactive protein (CRP) and plasma-free radicals. Elevated CRP levels have been suggested to be associated with disease progression in osteoarthritis. In our study, 29 subjects of the Pycnogenol group and 26 patients in the placebo group showed CRP levels higher than 3 mg/l at baseline. Comparison of blood specimens drawn at baseline and after 3-month treatment showed that Pycnogenol significantly decreased plasma free radicals to 70.1% of baseline values. Plasma CRP levels decreased from baseline 3.9 mg/l to 1.1 mg/l in the Pycnogenol group whereas the control group had initial values of 3.9 mg/l which decreased to 3.6 mg/l. The CRP decrease in the Pycnogenol was statistical significant as compared to the control group (P < 0.05). Fibrinogen levels were found to be lowered to 62.8% of initial values (P < 0.05) in response to Pycnogenol. No significant changes for plasma free radicals, CRP and fibrinogen were found in the placebo-treated group. The decrease of systemic inflammatory markers suggests that Pycnogenol may exert anti-inflammatory activity in osteoarthritic joints and patients did not present with other ailments or infections. The nature of the anti-inflammatory effects of Pycnogenol with regard to CRP warrants further investigation.

In 32 patients with chronic venous insufficiency and venous hypertension associated with ulcerations, the effects of the local application of a hydrogen peroxide cream (Crystacide) applied onto the skin was evaluated using a complex, proportional, microcirculatory model to assess and quantify venous microangiopathy after local treatment. A comparative group treated without Crystacide was included. Laser Doppler flowmetry was used to assess skin perfusion (flux and venoarteriolar response) in association with transcutaneous PO2 and PCO2 measurements. Local plasma free radicals were evaluated in the area surrounding the venous ulcer using the D-Roms test. Crystacide was applied around and on the ulcer for 10 days. Crystacide was more effective than the control treatments. PO2 was increased (improved, P < .05), and plasma free radicals, PCO2, and laser Doppler flowmetry were decreased (improving toward normal values, P < .05). Also, the ulcerated area was significantly smaller at 10 days in the Crystacide group in comparison with controls (P < .05). In the proportional microcirculatory model, all parameters indicated an important level of improvement significantly larger than in controls. In conclusion, in chronic venous insufficiency and venous ulcerations, local treatment with Crystacide (10 days) improves the microcirculation and decreases skin free radicals, thus improving healing.

Topical effects of heparins on the skin need deeper investigations. The lack of evidence is mainly due to the lack of large investments in this field. Three main local actions of heparin on the skin can be defined: (a) the anticoagulant action, (b) the microcirculatory-modulatory action determining important control of the microcirculation in case of excessive vasoconstriction or vasodilatation, and (c) the 'facilitatory action' on skin permeability allowing other drugs to diffuse better and faster into the skin (producing a therapeutic effect). These aspects have to be evaluated more extensively in both experimental and clinical conditions. Recent experimental studies demonstrate these effects of locally applied heparin. Therefore, key questions on local heparin administration such as skin penetration and the action on the local thrombi have promising answers. These observations suggest important clinical applications for local liposomal heparin. Both the potentials of local applications of heparin, particularly with new formulations, and some new aspects in the management of superficial vein thrombosis (SVT) can focus on locally applied heparin. SVT is an important clinical condition considering its frequency and the potentially heavy use of local heparin in this clinical problem. Results from new studies and observations presented in this issue of Angiology could be a window for suggesting new significant clinical applications and therapeutic solutions.

Local, topical effects of heparins on the skin still need deeper investigations. The lack of evidence is mainly due to the lack of large investments in this field. Three main local actions of heparin on the skin can be defined: (1) the anticoagulant action, (2) the microcirculatory-modulatory action determining important control of the microcirculation in case of excessive vasoconstriction or vasodilatation, and (3) the "facilitatory action" on skin permeability, allowing other drugs to diffuse better and faster into the skin (producing a therapeutic effect). These aspects have to be evaluated more extensively both in experimental and in clinical conditions as they may be clinically very important. Recent experimental studies indicate these effects of locally applied heparin. Therefore, key questions on local heparin administration such as skin penetration and the action on the local thrombi have a promising answer. These observations suggest important clinical applications for local liposomal heparin. Both the potentials of local applications of heparin, particularly with new formulations, and some new aspects in the management of superficial vein thrombosis can focus on locally applied heparin. Superficial vein thrombosis is an important clinical condition considering its frequency and the potentially large use of local heparin in this clinical problem. Results from new studies and observations presented in this issue of Angiology could be a window for suggesting new significant clinical applications and therapeutic solutions.

Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb, Lipohep, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.

The efficacy of a 2-month treatment with oral colostrum in the prevention of flu episodes compared with antiinfluenza vaccination was evaluated. Groups included healthy subjects without prophylaxis and those receiving both vaccination and colostrum. After 3 months of follow-up, the number of days with flu was 3 times higher in the non-colostrum subjects. The colostrum group had 13 episodes versus 14 in the colostrum + vaccination group, 41 in the group without prophylaxis, and 57 in nontreated subjects. Part 2 of the study had a similar protocol with 65 very high-risk cardiovascular subjects, all of whom had prophylaxis. The incidence of complications and hospital admission was higher in the group that received only a vaccination compared with the colostrum groups. Colostrum, both in healthy subjects and high-risk cardiovascular patients, is at least 3 times more effective than vaccination to prevent flu and is very cost-effective.

The presence of edema in different phases and stages of essential hypertension may be due to antihypertensive treatment. Some drugs may cause edema by inducing vasodilatation, increasing the capillary exchange surface and capillary filtration. Pycnogenol has an important anti-edema effect in diabetic microangiopathy and chronic venous insufficiency. This 8-week study evaluated capillary filtration in 2 comparable treatment groups with hypertension treated with a calcium antagonist (nifedipine) or angiotensin-converting enzyme inhibitor to define its efficacy in preventing edema caused by antihypertensives. A significant decrease in filtration was observed in the Pycnogenol groups. Pycnogenol controls this type of edema, it helps to prevent and limit long-term damage in the microcirculation in hypertensive patients, and allows the dose of anti-hypertensive drugs to be reduced in most patients.

The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd, United Kingdom) in patients with diabetic microangiopathy. Patients without a history of diabetic ulcerations were treated with Pycnogenol. Patients received oral Pycnogenol (50 mg capsules, 3 times daily for a total of 150 mg daily for 4 weeks). A group of 30 patients was included (severe microangiopathy); 30 comparable patients were observed as controls (no treatment during the observation period). All patients (age, 59 years; range, 55-68 years; male:female = 18:12) included in the treatment group completed the 4-week study. Also, all controls completed the follow-up period. There were no drop-outs. All included subjects had signs and symptoms of diabetic microangiopathy. The duration of diabetes-from the first signs/symptoms--was on average 7.5 years (SD = 3). After 4 weeks, microcirculatory and clinical evaluations showed a progressive decrease in skin flux at rest in the foot (indicating an improvement in the level of microangiopathy), a significant decrease in capillary filtration, and a significant improvement in the venoarteriolar response in all treated subjects. There were no visible effects in controls except a slight reduction in skin flux at rest in the foot. Treatment was well tolerated in both groups. In conclusion, this study confirms the clinical efficacy of Pycnogenol in patients with diabetic microangiopathy. The study indicates the clinical role of Pycnogenol in the management, treatment, and control of this common clinical problem. The treatment may be also useful to prevent diabetic ulcerations by controlling the level of microangiopathy.

Diabetic microangiopathy leads to lower limb ulcers that are very slow to heal. Pycnogenol was evaluated on diabetic ulcers in a controlled trial. Ulcer medications were used in 4 groups (30 patients): (1) systemic Pycnogenol and local application; (2) local Pycnogenol only; (3) oral Pycnogenol; and (4) medications only (control group). Ulcerated areas and symptom scores were more reduced with the combined oral and local treatment (P < .05). Oral and local treatment were less effective, but still improved compared with the controls. Combined treatment produced 89% complete healing at 6 weeks versus 84% with local treatment and 85% with oral treatment; healing in controls was 61%. The combined treatment group and oral only group had better microcirculation after the combined treatment. Combined local and systemic application of Pycnogenol may offer a new treatment of diabetic ulcers. Local treatment also speeds ulcer healing.

The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd., UK) in patients with severe chronic venous insufficiency (CVI) in comparison to the combination of diosmin and hesperidin (Daflon, Servier, France). A group of 86 patients with severe chronic venous insufficiency (CVI), venous hypertension, ankle swelling) and previous history of venous ulcerations received either oral Pycnogenol (capsules) 150 mg or 300 mg daily for 8 weeks or Daflon, 1,000 mg/day. All patients completed the study without dropouts. At the end of the study, microcirculatory results indicated: a progressive decrease of skin flux at rest (RF); a significant decrease in capillary filtration (RAS); an improvement in the symptomatic venous score (ASLS); a reduction in edema; a significant improvement (increase) in pO(2) and a decrease in pCO(2) in the Pycnogenol group. A significant level of improvement was reached after 4 weeks of treatment in most patients (p < .05) of the Pycnogenol group while clinical improvement was significant only in 6 subjects in the Daflon group. The positive effects of treatment with Pycnogenol after 8 weeks were significantly larger in comparison with the Daflon group. In conclusion, this study confirms the fast clinical efficacy of Pycnogenol in patients with chronic venous insufficiency and venous microangiopathy and its superiority-considering the evaluated parameters-to the combination of diosmin and hesperidin.

Damage to endothelial cells is common in vascular disorders and in reactions associated with transplantation. An elevated number of circulating endothelial cells indicates the extent of endothelial damage in a variety of disorders. In chronic venous insufficiency (CVI), the number of endothelial cells is abnormally increased, and this can be considered an important indication of endothelial damage. A group of 23 subjects with two levels of CVI (severe and very severe with previous ulcerations) with an increased endothelial cell count (seen by microscopy) was studied and treated for 4 weeks with oral Venoruton (0-[beta-hydroxyethyl]-rutosides) (1 g/day) to evaluate the effects of treatment on the circulating endothelial cells in blood taken from a peripheral leg vein. The controls comprised two groups with comparable age and sex distribution, one of healthy individuals and one of CVI subjects. After 4 weeks, a significant decrease was noted in endothelial cells both in subjects with CVI and in those with very severe CVI with previous ulcerations. This study suggests that endothelial cells may play a significant role in venous disease, being both an indication of severe disease and a further problem in itself. The use of Venoruton appears to decrease the number of circulating endothelial cells. This suggests an important role of this compound in protecting the endothelium and offers new potentially important therapeutic options that are not limited only to venous disease.

The aim of this independent study was to investigate differences in efficacy between oxerutins (Venoruton) and 500 mg micronized diosmin + hesperidin (D+H) (Daflon) in patients with chronic venous insufficiency (CVI), evaluating venous-related quality of life (Ve-QOL). A first group of 90 patients with severe venous hypertension (CVI, ankle swelling) was randomized to treatment with oxerutins or D+H. The oxerutins group received oral oxerutins (2 g/day); the D+H group received 3 (500 mg) tablets daily every 8 hours for 8 weeks. A second group of 122 comparable patients was included in a registry following the same study format. The 2 treatments were administered with the same methods and procedures. Clinical conditions were comparable. All patients completing 8 weeks of treatment were included in a registry. Specialists or general practitioners included patients when they considered that clinical conditions were compatible with treatment indications using 1 of the 2 treatments on the basis of their evaluation and experience. When cases were compatible with the registry, the prescribing physician communicated the case to our monitoring center. Patients were evaluated without interfering with their treatment. The main target of evaluation for this study was the change in Ve-QOL (range, 0-100) induced by treatment. A specific Ve-QOL questionnaire was used for this study. Ve-QOL score is a specific expression of the changes in QOL induced by CVI in patients between 35 and 75 years old (defined in our population studies) in which no other significant clinical disease is present (as a confounding factor affecting QOL). Two hundred twelve patients completed the 2 parts of the study. The 2 treatment groups were comparable for age and gender distribution. The mean age was 42 years (SD +/-5.5) in the oxerutins group and 41.5 (SD +/-6) in the D+H group. There were no differences in the severity of CVI between the treatment groups at inclusion. A significant decrease (46.8%, p <0.05) in Ve-QOL score; that is, improvement, was observed in the oxerutins group. The change in Ve-QOL was significantly less in the D+H group (15.5%). In conclusion, CVI, venous microangiopathy, and edema were significantly improved by the treatment with oxerutins; the improvement in QOL was significantly greater in the oxerutins group. The comparison with D+H indicates that oxerutins is comparatively more effective on Ve-QOL and on signs/symptoms of CVI.

Chronic venous insufficiency (CVI) causes a well-defined microangiopathy described as venous hypertensive microangiopathy (VHM) leading to venous ulcerations. VHM is mainly observed in the distal part of the leg, in the perimalleolar region. In VHM edema is the consequence of increased capillary pressure and reduced local clearance, and this affects local perfusion. The healing of venous ulcers is usually very slow. Many treatments are available, but there is still no standard. Oral Pycnogenol is effective in venous disease and particularly in controlling edema. The aim of this study was the evaluation of the local effects of Pycnogenol on ulcers healing associated with venous hypertension. The study lasted 6 weeks including 18 patients (16 completed the study) with venous ulcerations. The oral treatment with Pycnogenol was compared with a combination treatment including oral and local treatment. In subjects treated with the combination treatment (oral and local), venous ulcers healed better (there was a faster reduction in ulcerated area) in comparison with oral treatment only. According to this pilot study Pycnogenol appears to have an important role in local treatment of venous ulcers improving healing and signs/symptoms.

The aim of this independent study was to investigate differences in efficacy between HR, (0-[beta-hydroxyethyl]-rutosides) and D+H (500 mg, diosmin+hesperidin) in patients with chronic venous insufficiency (CVI). A first group of 90 patients with severe venous hypertension (CVI, ankle swelling) were randomized into an HR or a D+H group. The HR group received oral HR (2 g/day, 8 weeks); the D+H group received a 500 mg tablet 3 times daily for 8 weeks. A second group of comparable patients was included in a registry following the same study format. Patients were openly included; the 2 treatments were administered with the same methods and procedures. Clinical conditions were comparable to those described in the randomized study. Patients treated for at least 8 weeks were included in the registry. A number of physicians (specialists or general practitioners) included patients when they considered that clinical conditions were compatible with using 1 of the 2 treatments on the basis of their personal evaluation and experience. When cases were compatible with the registry, the prescribing physician communicated the case. Patients were evaluated without interfering with the treatment. Main targets of evaluation were skin flux at rest (RF), strain-gauge-derived rate of ankle swelling (RAS), and analogue symptoms score (ASLS). Ninety subjects completed the study in the first group; 122 in the second, registry group (total of 212 patients). The first and second (registry) groups and the 2 treatment groups were comparable for age and sex distribution. The pooled mean age was 42 years (SD +/-5.5) in the HR group (46+62 patients) and 41.5 (SD +/-6) in the D+H group (44+60 patients). Considering pooled data there were no differences in microcirculatory parameters between the pooled treatment groups at inclusion. A significant decrease (p<0.05) in RF and RAS was observed in the HR group at 8 weeks. The decrease in resting skin flux and in capillary filtration was associated with a significant improvement in signs/symptoms (analogue scale line) from an average of 9.4 (range 3-10) to 3.3 (4-6) (p<0.05). Significantly smaller variations were observed in the D+H group. The decrease in RF was 47.6% in the HR group vs 15.7% in the D+H group. The decrease in RAS was 40.9% in the HR group vs 12.8% in the D+H group. The decrease in ASLS was 64.8% in the HR group vs 12.9% in the comparative group. In conclusion venous microangiopathy and edema were improved by the treatment with HR both in the randomized study and in the pooled analysis. The comparison with D+H indicates that HR is comparatively more effective both on microcirculatory parameters and on signs/symptoms of CVI.
