RÉSUMÉ

BACKGROUND: Chronic venous insufficiency (CVI) is the consequence of venous valve reflux and/or venous flow obstruction and resulting venous hypertension in the lower extremities. The aim of this prospective supplement registry study was to evaluate the efficacy of compression stockings or Pycnogenol® in controlling symptoms and edema in CVI and their efficacy on microcirculatory parameters. METHODS: Two comparable groups of 30 subjects with CVI were observed for 4 months. RESULTS: Elastic compression was less tolerated than Pycnogenol® with 12 subjects being unable to follow the compression routine. No side effects due to supplementation were observed; tolerability of the supplementation was optimal. Ambulatory venous pressure (AVP) and refilling time (RT) at inclusion indicated a significant increase in venous pressure and reflux (refilling time <16 seconds). AVP and RT did not change after 4 months. Microcirculatory and clinical measurements were comparable at inclusion between the 2 groups. After 4 months, skin resting flux (RF) and skin PO2-PCO2 were significantly improved with Pycnogenol® compared to compression (P<0.05). The significant increase in skin PO2 and the decrease in PCO2 after Pycnogenol® intake were ascribed to the decrease in the abnormally high skin resting flux, a sign of better perfusion and skin nutritional supply. Pycnogenol® reduced leg volume, on average by 18.3% in the evening compared to 4.4% of reduction with compression (P<0.05) showing an important effect on edema. The venous Clinical Severity Score (VCSS) and the composite symptom score (CSS) decreased significantly in the Pycnogenol® group compared to compression, indicating a better improvement in microcirculatory perfusion and nutritional supply produced by the supplementation of Pycnogenol® in comparison with compression. Pycnogenol® significantly improved microcirculation and clinical symptoms in comparison with compression. The decrease in local oxidative stress (OS) at the distal perimalleolar region with Pycnogenol® was significant in comparison with compression (P<0.05). A lower local OS is an important metabolic indication of a better capillary perfusion with better nutritional exchanges. At the end of the registry study, four small ulcerations and skin breaks in four limbs (between 3 and 5 mm of maximum diameters) were observed in the compression group. No ulcerations or skin breaks were observed in the Pycnogenol® group. CONCLUSIONS: Pycnogenol® relieved edema, improved microcirculation in CVI patients and reduced stationary, interstitial fluid in comparison with compression. Most symptoms of CVI are associated with interstitial water retention; the presence of extra fluid in limb tissues alters perfusion and nutrient supply. Pycnogenol® supplementation reduced water and fluid accumulation in CVI limbs and improved microcirculation and local oxidative stress thus showing important anti-edema effects.

RÉSUMÉ

BACKGROUND: The aim of this study was to evaluate the effects of Robuvit® in preventing the progression of chronic hepatitis (CH) in non-alcoholic fatty liver disease (NAFLD) which encompasses the entire spectrum of fatty liver disease, from isolated steatosis to non-alcoholic steatohepatitis (NASH). METHODS: One group of patients followed the Standard management (SM) and were assigned as controls while the supplementation group followed the SM and additionally took 2 Robuvit® capsules daily for 3 months (200 mg/day). RESULTS: 34 subjects with NAFLD were included in the study. The two groups completing 90 days were comparable at baseline with 18 being supplemented with Robuvit® and 16 in the control group. The tolerability was very good, and no side effects were observed with the supplement. Fasting glucose levels were significantly lower after 3 months with Robuvit® (P<0.05) compared to controls. The increased serum aspartate aminotransferase levels (AST), considered the key metabolic value in these patients, decreased significantly with Robuvit® (P<0.05) compared to controls. Serum alanine aminotransferase levels (ALT) also decreased significantly with the supplement compared to controls (P<0.05). Platelet count and albumin levels improved significantly with Robuvit® (P<0.05) in comparison to standard management. No other significant changes were observed. The APRI score (the AST/platelet ratio index) was also decreased with the supplementation compared to controls (P<0.05). A high APRI score provides an estimate of the possibility of the liver to develop fibrosis and eventually cirrhosis. After Robuvit® supplementation, the ultrasound characterization showed a significant decrease in the size of the liver in association with a lower echogenicity, which represents less fibrotic changes due to collagen accumulation. CONCLUSIONS: Robuvit® improved liver function in NAFLD and prevented progression to liver fibrosis by improving hepatic metabolism in a relatively short period of time. Numerous people are affected by NAFLD, many of them with subclinical symptoms. But to date, there are no specific, definite treatment options. Prolonged evaluations of Robuvit® in a larger group of subjects is suggested.

RÉSUMÉ

This open pilot registry study aimed to evaluate and compare the prophylactic effects of Pycnogenol® or cranberry extract in subjects with previous, recurrent urinary tract infections (UTI) or interstitial cystitis (IC). Methods. Inclusion criteria were recurrent UTI or IC. One subject group was supplemented with 150 mg/day Pycnogenol®, another with 400 mg/day cranberry extract, and a group served as a control in a 2-month open follow-up. Results. 64 subjects with recurrent UTI/IC completed the study. The 3 groups of subjects were comparable at baseline. All subjects had significant symptoms (minor pain, stranguria, repeated need for urination, and lower, anterior abdominal pain) at inclusion. In the course of the study, the subjects reported no tolerability problems or side effects. The incidence of UTI symptoms, in comparison with the period before inclusion in the standard management (SM) group, decreased significantly; there was a more pronounced decrease in the rate of recurrent infections in the Pycnogenol® group (p < 0.05). The improvement in patients supplemented with Pycnogenol® was significantly superior to the effects of cranberry. At the end of the study, all subjects in the Pycnogenol® group were infection-free (p < 0.05vs. cranberry). Significantly, more subjects were completely symptom-free after 2 months of management with Pycnogenol® (20/22) than with SM (18/22) and cranberry (16/20). Conclusions. This pilot registry suggests that 60 days of Pycnogenol® supplementation possibly decrease the occurrence of UTIs and IC without side effects and with an efficacy superior to cranberry.

RÉSUMÉ

BACKGROUND: The aim of this pilot study was the evaluation of primary, idiopathic mucosal dryness (xerostomia or dry mouth) in subjects without cancer. METHODS: A group of non-diabetic subjects and a group of diabetics were managed with standard management (SM) or with SM+Pycnogenol® (150 mg/day) for 2 weeks. RESULTS: In total, 48 subjects were included in the study; 24 diabetics and 24 non-diabetics. 12 diabetics and 12 non-diabetics took Pycnogenol® and 12 diabetics and 12 non-diabetics were followed up with standard management only and served as controls. No side effects and no tolerability problems were observed with Pycnogenol®. The registry groups were comparable for characteristics and symptoms at baseline. All otherwise healthy subjects had a BMI<26 kg/m2. In 2 weeks, salivary flow and oxidative stress improved significantly in both groups of subjects (non-diabetics and diabetics) with 150 mg/day Pycnogenol® (P<0.05), while minimal improvements in salivary flow were seen with SM. The subjective score and the number of mucosal breaks and ulcerations, all minimal (<1 mm in length or diameter), were significantly decreased with Pycnogenol® supplementation (P<0.05) with minimal variations in the SM controls. Finally, the mean lysozyme level in parotid saliva samples was significantly increased in the Pycnogenol® group (P<0.05) both in diabetics and non-diabetics. CONCLUSIONS: Based on these preliminary results, Pycnogenol® could be a new, valid option for the treatment of xerostomia.

RÉSUMÉ

BACKGROUND: This retrospective registry study evaluated different managements on the development of post-thrombotic syndrome (PTS) and recurrent deep venous thrombosis (R-DVT). The effects of aspirin (100 mg/day), added to the "standard management" (SM) (IUA consensus), were observed in patients after a proximal DVT. METHODS: The study started after the anticoagulant period. Comparable groups used the mild-antithrombotic agent Pycnogenol® (200 mg/day), ticlopidine (250 mg/day) or sulodexide (500 ULS/day). RESULTS: The groups were comparable for sex and age distribution and clinical pictures. In the SM group, 222 patients completed the follow-up (72 months). With SM, the percentage of patients with R-DVT (requiring anticoagulants) was 17.2%; 19.8% of SM patients had a PTS. In the aspirin group (202 subjects), R-DVT was observed in 14.8% of patients; 17.32% had a PTS. The reduction in R-DVT and PTS with aspirin was significant (P<0.05) vs. the SM. There was no tolerability problem in subjects using Pycnogenol® (137 patients); they had a much lower incidence of R-DVT (5.8%) and PTS (6.5%) vs. SM and aspirin (P<0.05). Ticlopidine (121 patients) reduced the incidence of R-DVT (12.4%) and PTS (19.8% of patients) (P<0.05 vs. SM). With sulodexide the incidence of R-DVT was 6.7% (P<0.05 vs. SM); the incidence of PTS was 16.6% (P<0.05 vs. SM). The combined R-DVT+PT syndrome was observed in 14.9% of subjects using SM and in 12.9% of subjects using aspirin (P<0.05 vs. SM), in 3.6% of subjects managed with Pycnogenol® (<0.05% vs. aspirin and all other managements). The incidence was 10.74% with ticlopidine and 6.7% with sulodexide (both significantly lower than SM). CONCLUSIONS: Interaction between PTS and R-DVT are complex; recurrences cause more PTSs, and a post-thrombotic limb is prone to R-DVT. Aspirin, for patients that can tolerate it, reduces the occurrence of PTS and R-DVT. In addition, ticlopidine and sulodexide are effective. Pycnogenol® is the most effective and safe for R-DVT and particularly PTS. Its full range of anti-thrombotic activity is now under evaluation.

RÉSUMÉ

OBJECTIVE: In this study, we evaluated a novel delivery form of boswellic acids (Casperome®) in the management of signs and symptoms associated with ankle sprain grade II due to sport trauma. PATIENTS AND METHODS: In this supplement registry study, 72 otherwise healthy subjects with grade II ankle sprain induced by sport activities were advised to either follow a standard management (SM, 37 subjects) for the condition or the SM with the additional daily intake of 1 tablet containing 250 mg Casperome® (35 subjects). Subjects were allowed to use rescue medications (ketoprofen tablets, 25 mg/tablet), and their intake was measured at the end of the management period of 7 days. Each individual was subjected to several non-invasive examinations (self-reported pain at rest and under moderate exercise, range of active and passive movement, presence of local hematomas by ultrasonography) at the following time periods: at inclusion, to evaluate the basal conditions of the subject before the beginning of the study, at day 3 and at the end of the week to evaluate the response differences between the two groups. Additionally, a blood sample from the Casperome® treated subjects (34 out of 35 subjects) was taken at day 7 and analyzed for the systemic concentration of boswellic acids. RESULTS: The 72 individuals recruited in this study spontaneously decided which management to follow, either SM (n=37) or SM+Casperome® (n=35). Supplementation with Casperome® 250 mg/day showed beneficial effects in the reduction of signs and symptoms of ankle sprains evaluated at day 3 and day 7, and was shown to induce measurable plasma level of boswellic acids. Moreover, the supplementary use of Casperome® was well-tolerated and devoid of side effects. CONCLUSIONS: Our pilot registry study showed the effectiveness of Casperome® supplementation in improving recovery after ankle sprain of mild severity (grade II), suggesting a potentially beneficial role in relieving the trauma associated with sport activities and in decreasing the use of rescue drugs.

RÉSUMÉ

The aim of this registry study was to compare products used to control symptoms of CVI. Endpoints of the study were microcirculation, effects on volume changes, and symptoms (analogue scale). Pycnogenol, venoruton, troxerutin, the complex diosmin-hesperidin, Antistax, Mirtoselect (bilberry), escin, and the combination Venoruton-Pycnogenol (VE-PY) were compared with compressions. No safety or tolerability problems were observed. At inclusion, measurements in the groups were comparable: 1,051 patients completed the registry. Best performers : Venoruton, Pycnogenol, and the combination VE-PY produced the best effects on skin flux. These products and the combination VE-PY better improved PO 2 and PCO 2 . The edema score was decreased more effectively with the combination and with Pycnogenol. Venoruton; Antistax also had good results. Considering volumetry, the best performers were the combination PY-VE and the two single products Venoruton and Pycnogenol. Antistax results for edema were also good. The best improvement in symptoms score were obtained with Pycnogenol and compression. A larger decrease in oxidative stress was observed with Pycnogenol, Venoruton, and with the VE-PY combination. Good effects of Antistax were also observed. Parestesias were lower with Pycnogenol and with Antistax. Considering the need for interventions, the best performers were Pycnogenol, VE-PY, and compression. The efficacy of Pycnogenol and the combination are competitive with stockings that do not have the same tolerability in warmer climates. A larger and more prolonged evaluation is suggested to evaluate cost-efficacy (and non-interference with drugs) of these products in the management of CVI. The registry is in progress; other products are in evaluation.

RÉSUMÉ

This open registry aimed to evaluate the clinical evolution of postpartum varicose veins (VVs), in healthy women after the second pregnancy, how these veins regain shape and competence, and possible treatments. The registry included two groups of women: (1) those who used elastic compression stockings, and (2) who used an oral venotonic agent (Pycnogenol, 100 mg/d). A total of 12 evaluation targets were established. Minor symptoms were scored in an analogue scale line. A visual analogue scale line evaluated the overall satisfaction relative to elastic compression or Pycnogenol. Overall 133 women completed the registry evaluation with at least 3 months of follow-up. The resulting two registry groups were comparable. At 3 and 6 months in the Pycnogenol group the number of veins and incompetent sites were lower. At 6 months there were 13.3% of patients with edema in controls versus 3.2% in the Pycnogenol group. Spider veins decreased in Pycnogenol patients. Cramps and other minor symptoms were less common in the Pycnogenol group. In both groups there was a significant improvement at 6 months with better results in the Pycnogenol group. The need for treatment was limited with a decreased need for sclerotherapy, surgery, and conservative treatments in the Pycnogenol group. The overall satisfaction was higher among Pycnogenol patients, and compliance was optimal. Re-evaluation at 12 months indicated that the variations in VVs and spider vein clusters and the associated symptoms did not change. Most remodeling appeared to happen within 6 months after the pregnancy. It was concluded that the use of Pycnogenol improves signs/symptoms of postpartum VVs, and venous function and shape seem to return faster to prepartum, physiological pattern with its use.

RÉSUMÉ

AIM: The aim of this registry study was to evaluate the effects of supplementation with Robuvit® (French Quercus robur extract) capsules in subjects with Chronic Fatigue Syndrome (CFS) associated with an increased oxidative stress. Robuvit is a wood extract from Quercus robur (Horphag Research) used to improve liver dysfunction and chronic fatigue. After excluding any disease, subjects observed a defined management plan to improve CFS. Signs/symptoms had been present for more than 6 months in association with an increase in oxidative stress (measured as plasma free radicals). Blood tests were within normal values. METHODS: The registry study included 38 CFS subjects and 42 comparable controls. There were no dropouts in the 4 weeks of follow-up; the subjects were evaluated for a further period of 6 months. The management plan included: improved/increased sleep; reduction/abolition in smoking and alcohol or any other agent that may have affected them; control of diet, increase in dietary proteins; good hydration; rest (1/2-1 h/day) and exercise (at least 30 min/day); planned relaxation time; increased time in open spaces. In the Robuvit® supplementation group 300 mg/day of Robuvit® was used. RESULTS: Symptoms improved in both groups with a significantly more important improvement in the supplement group (P<0.05). The single items in the Multidimensional Assessment of Fatigue (MAF) questionnaire were statistically better improved (P<0.05) in the supplement group. A parallel improvement in oxidative stress was observed in the supplemented subjects. In the follow up, at 6 months no organic disease was discovered or disease markers found. CONCLUSION: This preliminary registry indicates that supplementation with Robuvit® improves CFS in otherwise healthy subjects with no presence of clinical disease or risk conditions. The effects of Robuvit® in CFS may be partially mediated by a clear reduction of plasma free radicals and oxidative stress.

RÉSUMÉ

AIM: The aim of the study was to evaluate the effect of the nutritional supplements Pycnogenol® and total triterpenic fraction of Centella asiatica (TTFCA) on atherosclerosis progression in low-risk asymptomatic subjects with carotid or femoral stenosing plaques. METHODS: This was an observational pilot, substudy of the San Valentino epidemiological cardiovascular study. The study included 824 subjects aged 45-60 without any conventional risk factors who had a stenosing atherosclerotic plaque (>50-60%) in at least one carotid or common femoral bifurcation, allocated into 6 groups: Group 1 (Controls): management was based on education, exercise, diet and lifestyle changes. This same management plan was used in all other groups; group 2: Pycnogenol® 50 mg/day; group 3: Pycnogenol® 100 mg/day; group 4: Aspirin® 100 mg/day or ticlopidine 250 mg/day if intolerant to aspirin; group 5: Aspirin® 100 mg/day and Pycnogenol® 100 mg/day; group 6: Pycnogenol® 100 mg/day plus TTFCA 100 mg/day. The follow-up lasted 42 months. Plaque progression was assessed using the ultrasonic arterial score based on the arterial wall morphology and the number of plaques that progressed and on the number of subjects that had cardiovascular events. A secondary endpoint was to evaluate the changes in oxidative stress at baseline and at 42 months. RESULTS: The ultrasonic score increased significantly in groups 1, 2, and 4 (>1%) but not in groups 3, 5 and 6 (<1%) suggesting a beneficial effect of Pycnogenol® 100 mg. Considering the percent of patients that progressed from class V (asymptomatic) to VI (symptomatic) there was a progression of plaques in 48.09% of controls. In the Pycnogenol® 100 (group 3, 10.4%) and in the Aspirin®+ Pycnogenol® (group 5, 10.68%) progression was half of what observed with antiplatelet agent (group 4, 20.93%); in the TTFCA+ Pycnogenol®group (group 6) progression was 7.4 times lower than in controls; 3.22 times lower than in the antiplatelet agents group (4). Events (hospital admission, specialized care) were observed in 16.03% of controls; there were 8.83% of subjects with events with Pycnogenol® 50 mg and 8% in group 3 (Pycnogenol® 100 mg). In group 4 (antiplatelets), 8.52% of subjects had events; in group 5, 6.87% of subjects had events and in group 6 (TTFCA+ Pycnogenol®) only 4.41% had events (this was the lowest event rate; P<0.05). All treatment groups had a significantly lower event rate (P<0.05) in comparison with controls. Considering treatments groups 2, 3, 5, 6 had a lower number (P<0.05) of subjects in need of cardiovascular management in comparison with controls. The need for risk factor management was higher in controls and lower in group 6 (P<0.05). In groups 2 to 6 the need for risk factor management was lower than in controls (P<0.05). Including all events (hospital admission, need for treatment or for risk management) 51.9% of controls were involved. In the other groups there was a reduction (from a -9.28% reduction in group 2 to a -26% in group 6) (P<0.002). The most important reduction (higher that in all groups; P<0.05) was in group 6. At 42 months, oxidative stress in all the Pycnogenol® groups was less than in the control group. In the combined group of Pycnogenol® and TTFCA the oxidative stress was less than with Pycnogenol® alone (P<0.001). CONCLUSION: Pycnogenol® and the combination of Pycnogenol® +TTFCA appear to reduce the progression of subclinical arterial plaques and the progression to clinical stages. The reduction in plaque and clinical progression was associated with a reduction in oxidative stress. The results justify a large, randomized, controlled study to demonstrate the efficacy of the combined Pycnogenol® and TTFCA prophylactic therapy in preclinical atherosclerosis.

RÉSUMÉ

AIM: This registry study aimed to evaluate the effects of supplementation with pycnogenol on altered endothelial function (EF) in borderline hypertensive, hyperlipidemic and hyperglycemic subjects without atherosclerotic changes in their main arteries and no coronary artery disease. METHODS: Flow mediated dilatation (FMD) and endothelium-independent (EID) dilatation were measured with brachial ultrasound after occlusion. Also, after occlusion, laser Doppler (LDF) flux and distal straingauge flow were measured. Oxidative stress (oxstress) was evaluated at 8 and 12 weeks. 93 subjects with borderline symptoms were enrolled into the study: 32 hypertensives, 31 hyperlipidemics, 30 hyperglycemics. All participants were instructed to follow the best available management to control their symptoms. In addition to best management, half of the subjects in each group used 150 mg/day Pycnogenol(®). 31 normal subjects were included as control. RESULTS: After 12 weeks metabolic values and blood pressure were back to normal in all subjects. Values were slightly better under Pycnogenol(®). FMD increased after 8 weeks from an average 5.3;3.4% to 8.2;2.2% with a further increase to 8.8;3.1% (P<0.05) at 12 weeks. No effects were found in controls and normal subjects. EID of normal subjects was consistently higher with 26%. LDF skin flux increased with Pycnogenol(®) at 8 weeks and 12 weeks. The final flux increase was not different from normal values. In controls flux after occlusion was not improved at 8 weeks; there was a significant but minor increase at 12 weeks. Flux increases were superior in all Pycnogenol(®) subjects. In Pycnogenol(®) subjects, limb flow after occlusion increased at 8 weeks with a further increase at 12 weeks. In controls inclusion flow after occlusion was comparable at 8 and 12 weeks. Oxidative stress was significantly decreased in Pycnogenol(®) subjects at 8 and 12 weeks. Minor differences were observed in controls. CONCLUSION: This open registry study indicates that Pycnogenol(®) improves EF in preclinical, borderline subjects in a macro-microcirculatory model. This observation may suggest an important preventive possibility for borderline hypertensive, hyperglycemic and hyperlipidemic subjects.

RÉSUMÉ

PURPOSE: To present the use of intravenous prostaglandin E1 (PGE1), a powerful vasodilator of the microcirculation, in the treatment of an ischemic diabetic eye. METHODS: A 27-year-old diabetic man with ischemic diabetic retinopathy and glaucoma had a decreased visual acuity of no light perception in his right eye and hand motions in his left eye. He was started on intravenous PGE1 and has been treated for over 4.5 years. RESULTS: The visual acuity in his right eye remained unchanged and in his left eye improved gradually to 1.5/30. He has been stable for 4.5 years. CONCLUSION: Intravenous PGE1 may be useful in ischemic diabetic eyes to improve the ocular blood flow and visual acuity. It is safe and tolerated well.

RÉSUMÉ

AIM: This registry study aimed to evaluate the use of Pycnogenol® (pine bark extract), an anti-inflammatory, anti-oxidant and anti-edema natural compound, on symptoms of common cold. Main targets were the evaluation in otherwise healthy subjects of signs/symptoms, the reduction in days of disease, and the prevention of complications. METHODS: All subjects used the "best management" for colds and one group added Pycnogenol® capsules (50 mg, bid/die) from day zero. The resulting registry groups were comparable. A total of 70 subjects used Pycnogenol® and 76 acted as controls. RESULTS: The number of days with a perceived cold affecting the patients was reduced in the supplement group (3.1;0.4 days) in comparison with controls (4.2;0.2). Lost working days were significantly decreased in the supplement group (0.55;0.3 versus 0.67;0.3 in controls). The need to use any other compound (on demand basis; OTC products) to manage symptoms and the occurrence of any clinically significant complications were significantly lower in the Pycnogenol® group. The most frequent complications were the extension of the cold to a period longer than 4 days, a tracheal extension and a bronchial involvement. Pycnogenol® was significantly effective in reducing the number of complications. The daily evolution of the "pillar cold signs" indicates a significantly faster resolution in the supplement group. With supplementation the decrease in symptom scores appears to be significantly more important. Pycnogenol® supplementation appears to make regression faster for all symptoms in comparison with controls. CONCLUSION: In this pilot registry, Pycnogenol® appears to decrease symptoms of cold and shorten its course also preventing some complications.

RÉSUMÉ

AIM: The aim of this open, observational registry was to evaluate the effects of antithrombotic treatment on the development of postthrombotic syndrome (PTS): the effects of "standard management" (SM; according to International Union of Angiology guidelines) were compared to SM in association with sulodexide or aspirin. METHODS: Postthrombotic syndrome occurrence was observed in 3 nonparallel groups after deep venous thrombosis (DVT); the registry started after the end of the anticoagulation period. The target was to observe the occurrence of PTS in 5 years. Three possible options were suggested to the patients, and the patients and their caregivers defined the type of management. A group of 167 patients was involved in the SM with reevaluation every 6 months; the sulodexide group included 124 patients and the aspirin group included 48 patients. RESULTS: The 3 groups were clinically similar and comparable for age and sex distribution. Of the 167 patients in the SM group, 154 patients completed 60 months of follow-up. The percentage of patients with PTS in the SM group ranged from 14.9% (1 year after the end of anticoagulation) to 19.5% (60 months). In the nonparallel group using sulodexide (124 comparable patients at inclusion; 115 at 60 months), the percentage of PTS was variable from 8.8% (1 year after anticoagulants) to 12.17% at 60 months. These percentages are significantly lower than those observed with SM. In the nonparallel aspirin group (48 patients at inclusion and 34 at 54 months), there was a PTS incidence of 23.5% at 54 months (vs 12.17% in the sulodexide group and 18.23% in the SM group). The incidence of PTS was significantly higher in comparison with the other 2 groups. The incidence of PTS was lower in the sulodexide group in comparison with the 2 other groups. CONCLUSIONS: Sulodexide administration after DVT appears to be effective in preventing PTS in association with recommended management and a number of recurrent DVTs. Modalities of treatment, dosages, and timing of administration should be explored in more comprehensive and complete studies.

RÉSUMÉ

AIM: The aim of the study was the evaluation of supplementation with Pycnogenol®, French maritime pine bark extract (registered trademark of Horphag Research Ltd.) to improve the effects of the management of psoriasis and reduce the need for treatments. METHODS: Patients (age range 30-45) with moderate/severe plaque psoriasis were included in a 12-week registry study that did not interfere with 'standard management'. The minimum Psoriasis Area Severity Index (PASI) score at inclusion was 10. Subjects with 10-29% (grade 2) and 30-49% (grade 3) of involved area were included. Oxidative stress (plasma free radicals) was measured. Patient-reported measures included the Dermatology Life Quality Index (DLQI). The supplement was used at a dosage of 150 mg/day (50 mg three times daily). RESULTS: The two registry groups (standard management and standard management+supplementation) were comparable. Dropouts were due to logistical problems. Single PASI items were evaluated: a decrease in the affected body area in boths groups was observed. The decrease in affected areas was more pronounced in the Pycnogenol group in all body regions. The severity score (erythema, induration, desquamation) improved more significantly with Pycnogenol. Considering the water content of skin in all areas, the increase was higher with Pycnogenol. The quantity of exfoliating cells (score from -5 to +5) was significantly reduced in both groups, with a better action using Pycnogenol. Skin moisture improved with treatment in all subjects, with better effects using Pycnogenol. Using a modified (12 items) DLQI indicating how much psoriasis had affected the patient's life in the previous week, Pycnogenol-supplemented subjects performed better for each single parameter in comparison with standard management. Improvement in the treatment time (-32% in comparison with standard management) and costs (decreased on average 36.4% in comparison with standard management) were observed in the supplement group. A decrease in consumption of other drugs was observed with the supplement. Oxidative stress was significantly lower in the supplement group at 12 weeks. CONCLUSION: These results indicate the efficacy of Pycnogenol supplementation in improving control of the most common clinical aspects of psoriasis and in reducing oxidative stress. Further studies may indicate the possible systemic or local use of Pycnogenol and its role in controlling side effects and costs of standard management.

RÉSUMÉ

AIM: The aim of this registry study was to evaluate the efficacy of Pycnogenol® (Horphag Research Ltd.), a standardized extract from the French maritime pine bark, to control signs/symptoms and prevent complications associated with hemorrhoids in the months after delivery in healthy women. METHODS: Women with hemorrhoids after their second pregnancy were included within the third month after pregnancy. Pycnogenol dosage was 150 mg/day for 6 months. Symptoms for 4th and 3rd degree hemorrhoids were evaluated. RESULTS: The registry groups were comparable. For 4th degree hemorrhoids, main symptoms were reduced after 6 months in all patients, but the group using Pycnogenol in addition to standard best management showed more improvement. In patients with 3rd degree hemorrhoids, symptoms were reduced in both management groups at 6 months; with Pycnogenol the reduction in symptoms scores was significantly better. At 6 months 18/24 subjects (75%) in the Pycnogenol group were symptom-free in comparison with 14/25 (56%) in controls. In the 4th degree hemorrhoid group, 7/10 patients (70%) in the Pycnogenol group were symptom-free at 6 months in comparison with 4/11 subjects (36%) in the best management group. No significant side effects were observed. CONCLUSION: Pycnogenol appears to positively affect hemorrhoid signs and symptoms in the months after pregnancy.

RÉSUMÉ

AIM: The aim of this registry study was to evaluate the evolution of moderate functional hepatic failure (MTHF) using a proprietary new oak wood supplement (Robuvit®) extracted from Quercus Robur. Recent studies have indicated the protective effect of oak wood extracts on liver injury. Quercus wood extracts have shown hepatoprotective effect on initial induced liver-injury. METHODS: This registry included a total of 75 patients with MTHF characterized by: decreased albumin levels; increased total bilirubin, altered hepatic functions enzymes, increased oxidative stress, negative viral hepatitis markers. RESULTS: The two groups (best management in comparison with best management+ Robuvit®) were comparable: 32 Robuvit® patients and 29 comparable controls) completed the 12-week registry. At inclusion, the blood parameter values in the two groups were comparable. At the end of the supplementation period, the increase in albumin levels was significantly (P<0.05 at 12 weeks) faster and higher in the Robuvit® group. The decrease in ALT-SGPT and AST-ASAT was significant in the supplement group (P<0.05 at 4 and 12 weeks); the tests were normalized at 4 and 12 weeks. Controls remained out of the normal range for more than 12 weeks. Alkaline phosphatase was normalized at 4 and 12 weeks in Robuvit® patients; they were decreased, but not normalized in controls at 4 weeks (Robuvit® group's values were significantly better; P<0.05). Values were normalized in controls (significantly higher in comparison with Robuvit®; P<0.05) at 12 weeks. Total bilirubin was normalized in Robuvit® subjects at 4 and 12 weeks. Results were significantly better in comparison with controls (P<0.05). Direct bilirubin values increased more in the Robuvit® group at 4 and 12 weeks (P<0.05). Gamma GT values were normalized at 4 and 12 weeks in the Robuvit® group. There was a less important decrease in controls (P<0.05) without normalization at 12 weeks. Plasma free radicals increased at inclusion showed a significant decrease in Robuvit® subject (at 4 and 12 weeks) with normalization at 12 weeks. Persisting, elevated values in controls were observed even at 12 weeks (P<0.05). ESR and CRP decreased in both groups with a more important decrease in the Robuvit® group (P<0.05). Hepatitis markers were negative when repeated at 4 and 12 weeks. CONCLUSION: Data from this pilot, supplement registry study indicate a significant protective activity of Robuvit®, associated with a very good safety profile, in patients with temporary hepatic failure. The activity of Robuvit® seems to be mediated by its anti-inflammatory activity.

RÉSUMÉ

AIM: The aim of the study was to evaluate the effect of the nutritional supplements Pycnogenol and TECA (total triterpenic fraction of Centella Asiatica) on atherosclerosis progression in low-risk asymptomatic subjects with carotid or femoral non-stenosing plaques. METHODS: This was an observational pilot substudy of the San Valentino epidemiological cardiovascular study. The study included 1363 subjects aged 45-60 without any conventional risk factors who had non stenosing atherosclerotic plaques (<50%) in at least one carotid or common femoral bifurcation, allocated into 6 groups: Group 1 (CONTROLS): management was based on education, exercise, diet and lifestyle changes. This same management plan was used in all groups; Group 2 Pycnogenol 50 mg/day; Group 3 Pycnogenol 100 mg/day; Group 4 Aspirin 100 mg/day or Ticlopidine 250 mg/day if intolerant to aspirin; Group 5 Aspirin 100 mg/day and Pycnogenol 100 mg/day; Group 6 Pycnogenol 100 mg/day plus TECA (total triterpenic fraction of Centella Asiatica) 100 mg/day. There was a six monthly follow-up up to 30 months. Plaque progression was assessed using the ultrasonic arterial score based on the arterial wall morphology and the number of plaques that progressed from the non-stenotic to the stenotic group. A secondary endpoint was to evaluate the changes in oxidative stress at baseline and at 30 months. RESULTS: The ultrasonic score increased significantly in groups 1, 2 and 4 but not in groups 3, 5 and 6 suggesting a beneficial effect of Pycnogenol 100 mg. The percentage of plaques that progressed from class IV to class V was 8.4% in group 2, 5.3% in group 3, 4% in group 5 and 1.1% in group 6 (P<0.0001) compared with 16.6% in group 4 (aspirin) and 21.3% in the control group suggesting a beneficial effect of Pycnogenol. The lowest rate of progression was in group 6 (Pycnogenol plus TECA). At 30 months, the oxidative stress in all the Pycnogenol groups was less than in the control group. The oxidative stress was lower in the Pycnogenol 100 mg group than the Pycnogenol 50 mg group (P<0.0001). In the combined group of Pycnogenol and TECA the oxidative stress was less than the Pycnogenol alone (P<0.001). CONCLUSION: Pycnogenol and the combination of Pycnogenol+TECA appear to reduce the progression of subclinical arterial lesions in low-risk asymptomatic subjects. The reduction in plaque progression was associated with a reduction in oxidative stress. The results justify a large randomized controlled study to demonstrate the efficacy of the combined Pycnogenol and TECA prophylactic therapy in subclinical atherosclerosis.

RÉSUMÉ

UNLABELLED: The aim of the present pilot, registry study was an assessment in a supplement study of FlexiQule (standardized Boswellia extract) capsules in the supplementary management of patients with symptomatic knee osteoarthritis (OA) also treated with the "standard management" (SM) in comparison with a group of patients only managed with SM. METHODS: This 4-week study included patients with symptomatic knee arthrosis (X-ray). Registry subjects were able to perform a treadmill walking test and to understand questions from the WOMAC questionnaire. Exclusion criteria were conditions requiring drug treatment, Body Mass Index >25, metabolic disorders, surgery within three months prior to inclusion, oncological condition or inability to walk. RESULTS: Twenty-seven registry subjects using the supplement+SM and 28 using only SM completed the registry; at inclusion, the two groups were comparable including Karnofsky scale, WOMAC Score and the Treadmill Test. Of the subjects completing the registry 24 preferred to use the combination SM and the supplement. Safety evaluation: no problems - indicating the suspension of the supplementation ­ were observed. Routine blood tests were normal at inclusion and did not significantly vary at 4 weeks. The Karnofski Scale at 4 weeks was improved in both groups: from 74.3;3.1 to 88.9;5.3 (P<0.05) in the Boswellia group in comparison with a variation from 75.3;5.2 to 79.4;3.3 (P<0.05) in the SM. The effects of the supplement were significantly higher (P<0.05). The WOMAC Score was decreased significantly more in the supplement+SM group in comparison with controls considering pain, stiffness and physical functions (P<0.05). Social/emotional functions improved better with the supplement (P<0.05). Both groups improved their walking distance at 4 weeks. The improvement was higher (P<0.05) in the Boswellia group. The need for other drugs or tests during the registry period was reduced more in the supplement group (P<0.05). CONCLUSION: The difference between SM and the supplementation associated to SM was significant) in favor of the supplementation with Boswellia for all target measurements evaluated in the registry at 4 weeks.
