RESUMO
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.

RESUMO
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.

AIM: Based on the results of the soluble antioxidants test (SAT), we have produced a combination of oral antioxidants aimed at increasing the antioxidant power of saliva. Several antioxidants are included in this product (Vit E, beta-carotene, Vit A, Vit C, polyphenols, cathechins, ellagic acid, anthocyanins, coenzyme Q10 and pyridoxine in association with Se, Zn, L-cysteine). The aim of this registry study was to evaluate the efficacy of these antioxidants in saliva, plasma and urines. METHODS: MF Odontovis, an antioxidant complex, was administered to healthy subjects in the evening for one week with a final administration in the morning. RESULTS: Plasma, urine and saliva showed an increase in antioxidant power following both the evening administration and the final morning administration. The antioxidant action appeared to be present even at night when salival secretion is lower. Plasma SAT levels (SATs) in the morning following evening treatment were increased by 21% in comparison with controls. Morning administration increased levels up to 34% when measured 4 hours after treatment. Comparable increases were observed in saliva (SATs and morning values were +44 %; +58% two hours after morning administration and +28 % after 4 hours). In urine the evening administration caused an increase in antioxidant power (+6%). CONCLUSION: This study indicated that antioxidant levels can be increased with specific nutritional supplement. The clinical value of an increased antioxidant power in biological fluids, particularly in saliva, may be relevant for future trials of prevention and treatment.

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.

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.

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.

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.

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 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 study was to evaluate the prevention of edema during long-haul flights with an oral, anti-edema and antithrombotic agent (Pycnogenol, Horphag, Research Management SA, Geneva, Switzerland) in asymptomatic subjects. The assessment of edema was performed by evaluating an analogue scale, the rate of ankle swelling by strain-gauge derived rate of ankle swelling (RAS), and by assessing the ankle circumference variation. The study included 211 subjects; 169 completed the study (88 in the control group and 81 in the Pycnogenol group). There were no important differences between the two groups (comparable for age, gender, weight, body mass index, and pattern distribution). The edema score, the RAS, and the circumference at inclusion were also comparable. After the flight in those treated with Pycnogenol, the edema score was increased only by 17.9% (vs. an increase of 58.3% in the control group) (p<0.05). The RAS, evaluated in 22 subjects in the Pycnogenol group (age 44.5; SD 8) and in 23 in the control group (age 45; SD 9) was increased on average by 91% in the control group and 36% in the Pycnogenol group (p<0.05). The variation on circumference at the ankle was 6% in the Pycnogenol group (11% in the control group; p<0.05). These results indicate a positive effect of Pycnogenol on edema during long flights when considering subjective and objective data. No unwanted effects were observed.

The aim of this study was to evaluate the occurrence of deep venous thrombosis (DVT) and superficial vein thrombosis (SVT) and its prophylaxis with an oral anti-edema and antithrombotic agent (Pycnogenol, Horphag, Research Management SA, Geneva, Switzerland) in long-haul flights, in subjects at moderate to high-risk of DVT and SVT. The study pre-included 244 pre-selected subjects; 211 were included (33 were excluded for several reasons due to logistic problems) and 198 completed the study; 13 subjects were lost for follow-up at the end of the flight, all for non-medical problems (i.e., for difficult connections). All subjects were scanned within 90 minutes before the flight and within 2 hours after disembarking. Subjects were supplemented with 100 mg Pycnogenol per capsule. Treatment subjects received two capsules between 2 and 3 hours before flights with 250 mL of water; two capsules were taken 6 hours later with 250 mL of water and one capsule the next day. The control group received comparable placebo at the same intervals. The flight duration was on average 8 hours and 15 minutes (SD 55 min) (range, 7.45-12.33). In the control group there were five thrombotic events (one DVT and four superficial thromboses) while only nonthrombotic, localized phlebitis was observed in the Pycnogenol group (5.15% vs. no events; p<0.025). The ITT (intention to treat) analysis detects 13 failures in the control group (eight lost to follow up + five thrombotic events) of 105 subjects (12.4%) vs. five failures (4.7%; all lost, no thrombotic events) in the treatment group (p<0.025). No unwanted effects were observed. In conclusion, this study indicates that Pycnogenol treatment was effective in decreasing the number of thrombotic events (DVT and SVT) in moderate-to-high risk subjects, during long-haul flights.

Aescin and essential phospholipids (AEPL) in a gel was used in a microcirculatory model to assess the effects on skin perfusion in chronic venous insufficiency and severe venous hypertension. The aim of this efficacy study was to evaluate the efficacy of an AEPL gel on the microcirculation measuring transcutaneous skin PO(2) and PCO(2) in subjects with chronic venous insufficiency, venous hypertension (CVH), and venous microangiopathy. Transcutaneous PO(2) and PCO(2) were measured at the internal perimalleolar region. After 2 weeks of treatment with AEPL, all TcPO(2) individual values were increased and all PCO(2) values were decreased (p < 0.05). Average values were significantly changed toward normal. Therefore, considering skin PO(2) and PCO(2) variations, local treatment with AEPL in areas of venous microangiopathy is very effective in improving skin perfusion and nutrition and, possibly, in preventing venous ulcerations.

The aim of this study was the evaluation of the effects of Aescin + essential phospholipids (AEPL) gel on plasma free radicals (PFRs). In this study, ten patients with venous hypertension, no ulcerations or infections, venous microangiopathy, and varicose veins were treated with topical AEPL applied in a standard protocol. AEPL was applied for 2 weeks, three times daily at the same skin region (perimalleolar internal region at defined distance from the medial malleolus and from the anterior edge of the tibia). In subjects with venous hypertension, PFR values were higher than 420 Carr units. After treatment, the values of PRF decreased to almost normal as an effect of the massage with AEPL gel. The decrease in value was observed in all treatment subjects. A ranking system indicates that the AEPL preparation is active in all subjects who have venous microangiopathy. The decrease in PFR value was greater than 30% in all treatment subjects (p < 0.05). The decrease in PFR can be considered an important indication of an improvement in skin perfusion, which protects the skin from deterioration and eventually from venous ulcerations. The evaluation of PFR is an important new physiologic parameter that can be associated with other noninvasive tests to study the microcirculation and its evolution and improvement with systemic or topical medical treatment.

The aim of this study was to evaluate the development of edema, and superficial and deep vein thrombosis (DVT) prophylaxis with an oral profibrinolytic agent (Flite Tabs, 150 mg pinokinase, Aidan, Tempe, AZ, USA) in long-haul flights (7-8 hours), in high-risk subjects. A group of 300 subjects was included; 76 were excluded for several problems including concomitant treatments; 204 were randomized into 2 groups (active treatment or placebo) to evaluate the effects of prophylaxis with Flite Tabs. An exercise program was used in both groups. The femoral, popliteal, tibial, and superficial veins were scanned with ultrasound before and within 90 minutes after flights. Of the included subjects, 92 of 103 controls and 94 of 101 treated subjects completed the study. Dropouts were due to connection problems. Age, gender, and risk distribution were comparable in the groups. In the treatment group, no DVT was observed. In the control group, 5 subjects (5.4%) had a DVT and there were 2 superficial thromboses (7 events in 92 subjects; 7.6%). At inclusion, edema was comparable in the 2 groups. After flights there was an increase in score in controls (+12%) in comparison with a decrease (-15%) in the Flite Tabs group (the difference in variation was statistically significant). Intention-to-treat analysis for thrombotic events shows 18 failures in controls (11 lost to follow-up + 7 thrombotic events) of 92 subjects (19.6%) in comparison with 7 failures (of 94 subjects, equivalent to 7.4%) in the treatment group (p < 0.05). Events were asymptomatic. In conclusion, Flite Tabs were effective in reducing thrombotic events and in controlling edema in high-risk subjects in long flights.

The aim of this study was to evaluate deep venous thrombosis (DVT) prophylaxis with specific elastic stockings in long-haul flights (11-13 hours), in high-risk subjects. A group of 300 subjects was included; 76 were excluded for several problems including concomitant treatments; 224 were randomized into two groups (stockings vs. controls) to evaluate prophylaxis with below-knee stockings. An exercise program was used in both groups. Scholl (UK) Flight Socks (14-17 mmHg of pressure at the ankle) were used. DVT was diagnosed with ultrasound scanning. The femoral, popliteal, and tibia] veins were scanned before and within 90 minutes after the flights. Of the 205 included subjects, 102 controls and 103 treated subjects completed the study. Drop-outs were due to flight connection problems. Age, gender, and risk distributions were comparable in the two groups. In the treatment group (103 subjects; mean age, 42; SD 9; M:F, 55:48), one limited, distal DVT was observed (0.97%). In the control group (102 subjects; mean age, 42.1; SD 10.3; M:F, 56:46), six subjects (5.8%) had a DVT. There were no superficial thromboses. The difference in DVT incidence is significant (p<0.0025; six times greater in the control group). Intention-to-treat analysis counts 18 failures in the control group (12 lost to follow-up + six thromboses) of 112 subjects (15.8%) versus eight failures (7.3%) in the treatment group (p<0.05). The tolerability of the stockings was very good and there were no complaints or side effects. All events were asymptomatic. Considering these observations, Scholl Flight Socks are effective in reducing the incidence of DVT in high-risk subjects.

The aims of the study were to evaluate the short-term effects of a new thermosensitive, vitamin E (V-E) mousse on local free radicals (FR) and skin flux in diabetic microangiopathy. A group of 40 patients with diabetic microangiopathy was included. The variation in measurements of skin FR was evaluated by the D-Rom test. Subjects were between 45 and 65 years with type II diabetes and good metabolic control. E-mousse, a thermoactive preparation of acetate vitamin E (20%), was applied twice daily on the whole surface of the leg (below knee) and foot for 3 weeks. The contralateral leg was untreated acting as control. Subjects with age between 45 and 65 years with type II diabetes (diagnosed at least 5 years before) and good metabolic control (blood sugar < 180 mg/dL) were included after informed consent. Patients with uncontrolled diabetes, peripheral vascular disease, and severe lower limbs infections were excluded. Local free radicals (FR) and laser Doppler flux including the venoarteriolar response (VAR) were evaluated. The tolerability was evaluated by a semiquantitative score. Of the 40 included patients 34 completed the study. The 2 groups were comparable. At 3 weeks there was no decrease in FR in controls; the decrease in the treatment group was 45.3% (p < 0.05). Also in the treatment group RF decreased (p < 0.05) and the VARveno improved from an average of 21% to an average of 38% (p < 0.05). No significant variations were observed in the control group. The variation in symptomatic score was from a total value of 8 to 5 in the control group and from 8 to 1 in the treatment group (p < 0.02). Their tolerability was good. In conclusion local treatment with E-mousse for 3 weeks in diabetic microangiopathy improves skin microcirculation and the metabolic condition as shown by the decrease in FR.

In 20 patients with chronic venous insufficiency and venous hypertension associated with ulcerations, the effects of a new compound, applied onto the skin (Crystacide) were assessed in a randomized, controlled study. Duplex scanning was used to assess the presence of venous obstruction and incompetence, and microcirculatory methods were used to assess and quantify venous microangiopathy and to follow up subjects after local treatment with Crystacide. Laser Doppler flowmetry (LDF) was used to assess skin perfusion in association with transcutaneous (tc) partial pressure of oxygen (PO2) measurements. Local plasma free radicals (PFR) were evaluated in the area surrounding the venous ulcer, with the D-Rom test. Crystacide was applied around and on the ulcer for 10 days. Crystacide was more effective than the control treatment: PO2 was increased, PFR and LDF were decreased (flux increase is associated with venous hypertension), and the ulcer area was significantly smaller at 10 days in the Crystacide group in comparison with the placebo group (p<0.05). In conclusion, in venous ulcerations, local treatment with Crystacide (10 days) improves the microcirculation and decreases skin free radicals improving healing.

The study compared, by a prospective, randomized method, 6 treatment options: A: Sclerotherapy; B: High-dose sclerotherapy; C: Multiple ligations; D: Stab avulsion; E: Foam-sclerotherapy; F: Surgery (ligation) followed by sclerotherapy. Results were analyzed 10 years after inclusion and initial treatment. Endpoints of the study were variations in ambulatory venous pressure (AVP), refilling time (RT), presence of duplex-reflux, and number of recurrent or new incompetent venous sites. The number of patients, limbs, and treated venous segments were comparable in the 6 treatment groups, also comparable for age and sex distribution. The occurrence of new varicose veins at 5 years varied from 34% for group F (surgery + sclero) and ligation (C) to 44% for the foam + sclero group (E) and 48% for group A (dose 1 sclero). At 10 years the occurrence of new veins varied from 37% in F to 56% in A. At inclusion AVP was comparable in the different groups. At 10 years the decrease in AVP and the increase in RT (indicating decrease in reflux), was generally comparable in the different groups. Also at 10 years the number of new points of major incompetence was comparable in all treatment groups. These results indicate that, when correctly performed, all treatments may be similarly effective. "Standard," low-dose sclerotherapy appears to be less effective than high-dose sclero and foam-sclerotherapy which may obtain, in selected subjects, results comparable to surgery.
