ABSTRACT

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.

ABSTRACT

OBJECTIVE: Several experimental studies and clinical trials support the potential of bilberry (Vaccinium myrtillus L) extracts in promoting eye health and circulation. Many active ingredients have been isolated from the berries and leaves of the bilberry plant. However, anthocyanins represent the most widely studied bioactive compounds in this plant. PATIENTS AND METHODS: The aim of this registry, supplement study was to evaluate the effects of Mirtoselect® (standardized in 36% anthocyanins and obtained by an industrial extraction process that preserves the full range of the non-anthocyanin components, mainly natural sugars and polyphenols) in different types of retinal vasculopathies. In total, 140 patients with different types of retinopathy spontaneously decided to join one of the following groups: standard management (SM) only (n=38); SM associated with Mirtoselect® supplementation (n=47); SM associated with a generic bilberry extract supplementation (n=55). Retinal circulatory parameters and flow measurements of the retinal vessels were evaluated at the inclusion and after 6-months supplementation. RESULTS: Overall, significant improvements in several retinal circulatory parameters such as retinal blood flow velocity, with respect to the values at inclusion, were observed in both supplementation groups, especially in Mirtoselect® supplementation group. However, at 6 months, inter-group comparison revealed a statistical advantage in all tested parameters for Mirtoselect® supplementation groups. No side effects or tolerability concerns were reported. CONCLUSIONS: Our registry study suggests that Mirtoselect® supplementation could represent an effective and safe integrated approach for the treatment of different retinopathies.

ABSTRACT

OBJECTIVE: Curcumin is known to interrupt pro-inflammatory signalling and increases anti-oxidant protection, thus inhibiting the expression of inflammatory cytokines and the expression and function of inducible inflammatory enzymes. Together, these effects contribute to limit the onset and the progression of sarcopenia, due to the major role played by inflammation in the pathophysiology of this disease. This registry study evaluates the effects of Meriva® supplementation in otherwise healthy elderly subjects. PATIENTS AND METHODS: This was a registry, supplement study, conducted in healthy subjects > 65 years with apparent loss of strength and tiredness who freely decided to start one of the following interventions: (1) standard management (exercise, balanced diet including proteins) (n = 33); (2) standard management + Meriva® one tablet/day (n = 31); (3) standard management + Meriva® one tablet/day + other supplementation (n = 22). A number of functional and biochemical parameters were evaluated at baseline and after three months (hand grip, weight lifting, time/distance before feeling tired after cycling, walking and climbing stairs; general fitness, proteinuria, oxidative stress, Karnofsky scale; left ventricular ejection fraction). RESULTS: Significant improvements in all parameters, with respect to baseline values, were observed in the two supplementation groups (p < 0.05 for all comparisons). On the other hand, no improvement was observed in the standard management-only group. At three months, inter-group comparison revealed a statistical advantage in all parameters for both supplementation groups compared with the standard management-only group (p < 0.05 for all comparisons). CONCLUSIONS: Our registry study shows that the addition of Meriva® - either or not combined with other nutritional supplements - to standardized diet and exercise plan contributes to improve strength and physical performance in elderly subjects, potentially preventing the onset of sarcopenia.

ABSTRACT

OBJECTIVE: Knee Osteoarthritis (OA) is a chronic disease caused by the deterioration of cartilage in joints, which results in activation of the inflammatory response, pain, and impaired movement. Complementary therapies, particularly supplementation, in the management of moderate/severe knee OA have been gaining attention. This registry study aimed at evaluating the synergistic effect of Movardol®, a supplementation containing active ingredients with recognized anti-inflammatory activities on symptoms and levels of circulating biomarkers of knee OA. PATIENTS AND METHODS: 54 subjects with symptomatic, moderate knee OA freely decided to follow either a standard management (SM) (n = 26) or SM plus oral supplementation with Movardol® (n = 28). Movardol® supplementation containing N-acetyl-D-glucosamine, ginger, and Boswellia Serrata extract was taken at the following dosage: 3 tablets/day for one week and then 2 tablets/day. Several parameters were assessed at inclusion and after 1, 3 and 6 months: functional impairment by the Karnofsky Performance Scale Index; pain, stiffness, physical, social and emotional functions by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC); total and pain-free walking distance; circulating biomarkers of inflammation and oxidative stress. RESULTS: Significant improvements in the functional outcomes and pain-free walking distance were observed after 1, 3 and 6 months in OA patients supplemented with Movardol®. Moreover, all the signs/symptoms of disease assessed by the WOMAC tended to regress over a 6-month period in patients following SM+supplementation. Inflammatory markers and plasmatic content of reactive oxygen species decreased over 6 months, in supplemented patients. Movardol® supplementation resulted to be safe and well tolerated, also showing the beneficial effect in term of a decrease in pharmacological and non-pharmacological treatments and, consequently, reduction in management costs. CONCLUSIONS: These preliminary results indicate the efficacy and safety of Movardol® supplementation in the management of moderate knee OA.

ABSTRACT

The aim of this supplement, registry study was to evaluate the effects of the use of standardized, oral supplement (Phyto-Relief CC, Alchem). Phyto-Relief CC includes anti-inflammatory, anti-oxidant and anti- edema natural compounds. Increased salivation produced by ginger is useful in the prevention of cold episodes and on signs and symptoms associated to the episodes by increasing saliva and its content (i.e. lysozyme). Main targets of the study were the evaluation of the occurrence of episodes and the reduction of signs/symptoms, the reduction of days of disease, the reduction in the use of other treatments and the control of cold-related complications. RESULTS: The two resulting registry groups were comparable. There were 5 full episodes (lasting at least 3 days) of cold in 61 registry subjects (8.1%) in comparison with 17 cases in 63 subjects (26.98%) in controls. Phyto-Relief CC subjects - even in this time-limited and small study population registry - had 30.1% of the episodes of the control group with a reduction of 69.88% of the cold episodes (p<0.0221). Also in the following, continuation, third week only 3 episodes of cold were recorded in the Phyto- Relief CC group vs 6 (50% reduction) observed in controls. All the other chosen parameters were better in the supplement group (p<0.05). Affected days (2.9;1.1 vs 4.6; 1.2 in controls), lost working days (0.58;0.5 vs 1.02;0.43 in controls. The use of any other OTC product, nasal drops, aspirin, Vit C, antihistamines, aerosols, the number of complications after 4 days were better in the Phyto-Relief CC group. Disease 'extension' (to >4 days), particularly tracheal and bronchial extension were significantly less frequent (p<0.05) with the supplement. No safety or tolerability problem was observed. In conclusion this preliminary study shows that Phyto-Relief CC may help the evolution of cold if used early, when initial symptoms could be identified. More specific evaluations and larger prevention studies are needed.

ABSTRACT

The aim of this registry was to evaluate the management of initial symptoms of benign prostatic hyperthrophy (BPH) in otherwise healthy subjects, using Prostaquil® (Alchem) in a 8-week registry. Prostaquil was used at the dosage of 200 mg/day. The product includes Pygeum extract (100 mg) and Saw palmetto oil (35 mg). The two resulting groups standard management and supplement) were comparable. RESULTS: No side effects or comparability problems were observed and compliance was optimal with more than 95% of the capsules correctly used. Empting, frequency, intermittency, urgency, weak flow, straining, nocturia were all significantly improved with Prostaquil (p<0.05) and the improvement - globally and evaluating any single item - was significantly superior to the one observed in controls (p<0.05). Quality of life with the supplement was also significantly better in comparison with controls (p<0.05). The residual vescical volume was 94.7;5,8 ml in the supplement group at inclusion and decreased to 39.3;5 ml (p<0.05) at 8 weeks. This decrease was equivalent to a reduction of 58.5%(vs a decrease of 27.9% in controls)(p<0.05; ANOVA). In conclusion, the most common symptoms of BPH are controlled by Prostaquil a new standardized supplement including Pygeum.

ABSTRACT

This case report (supplement registry study) evaluated subjects with painful 'stress' arthritis of the hand mainly localized at the joints. The patients received a suggestion to follow a rehabilitation plan (standard management; SM). A second group also used the same SM in association with the oral, pharma-standard supplement FlexiQule (Alchem) a new standardized, phytosomal preparation manufactured from the Boswellia plant, which can be used for self-management in inflammatory conditions (150 mg / 3 times daily). The two resulting registry groups included 12 subjects using SM+Flexiqule and and 11 controls (SM only). The groups were comparable. Serology showed no significant alterations: only ESR was slightly elevated (minimal elevation). After 2 weeks, the ESR was normal in the supplement group and mildly elevated in controls (p<0.05%). The decrease in hypertermic areas was greater/faster (p<0.05) in the supplement group. The identification of a working stress and the localization to the dominant hand was comparable in both groups. At 2 weeks, the decrease in pain was significantly faster and more important with the supplement (p<0.05). The hand became more usable in time and the score was better with the supplement (p<0.05). No supplemented patient had to use other drugs, while in the control group 3 subjects eventually used NSAIDs to control pain and stiffness and one used corticosteroids. In conclusion, the natural extract Flexiqule was effective in controlling work-related stress arthritis (without inflammaìtory signs) over a 2 weeks period, better than only Standard Management. More prolonged and larger studies are needed.

ABSTRACT

AIM: The aim of this study was to use Pycnogenol® to reduce the recurrence of retinal vein thrombosis (RVT) after a first episode. Pycnogenol® is an anti-inflammatory, anti-edema and an antiplatelet agent with a "mild" antithrombotic activity. The registry, using Pycnogenol® was aimed at reducing the number of repeated episodes of RVT. METHODS: Possible management options--chosen by patients--were: standard management; standard management + oral Aspirin® 100 mg once/day (if there were no tolerability problems before admission); standard management + Pycnogenol® two 50 mg capsules per day (for a total of 100 mg/day). Number of subjects, age, sex, distribution, percentage of smokers, and vision were comparable. RESULTS: Recurrent RVT was seen in 17.39% of controls and in 3.56% of subjects supplemented with Pycnogenol® (P<0.05 vs. controls). There was RVT in 15.38% of the subjects using Aspirin®. The incidence of RVT was 4.88 times higher with standard management in comparison with the supplement group and 4.32 lower with Pycnogenol® supplementation in comparison with Aspirin®. Vision level was better with Pycnogenol® (20/25 at nine months; P<0.05). With Pycnogenol®, edema at the retinal level was also significantly reduced compared to the other groups. Pycnogenol® has a very good safety profile. In the Aspirin® group 26 completed 9 months and 6 subjects dropped out for tolerability problems. In the Aspirin® group, 2 minor, subclinical, retinal, hemorrhagic episodes during the follow-up were observed (2 subjects out of 26, equivalent to 7.69%). This pilot registry indicates that Pycnogenol® seems to reduce the recurrence of RVT without side effects. It does not induce new hemorrhagic episodes that may be theoretically linked to the use of Aspirin® (or other antiplatelets). CONCLUSION: Larger studies should be planned involving a wider range of conditions, diseases and risk factors associated to RVT and to its recurrence.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

AIM: The aim of this supplement study was to evaluate French oak wood extract (Robuvit®, Horphag Research Ltd) used as a supplement in association with a defined management plan for chronic fatigue syndrome (CFS) in healthy subjects with CFS, a condition that has, so far, no specific treatment or management standards. METHODS: Robuvit® is a new proprietary and exclusive extract of oak wood with important antoxidant actions. The dosage of the supplementation was 200 mg/day for at least 6 months. The CFS questionnaire and the Brief Mood Introspection Scale (BMIS) questionnaire were used to evaluate mood variations associated with CFS patients. The CFS form includes an analogue scale to record the variations of single symptoms with a score range of 0-10. At inclusion into the registry study, at least 5 symptoms were present. All subjects (age range 35-44; BMI range 24-26) with CFS were tested for oxidative stress: 61 out of 91 subjects had an increased value of oxidative stress. The BMIS scale evaluating mood changes in time was also used. The evaluation was repeated at 3 and 6 months. RESULTS: Out of 91 eligible subjects with CFS, 48 subjects (31 with increased oxidative stress) were accepted as part of the supplement registry study using Robuvit; 43 (30 with increased oxidative stress) were accepted as controls using only the management plan. In the Robuvit® group there were 3 drop outs; also 3 controls were lost. Oxidative stress was increased in 64.58% of subjects that used Robuvit and in 69.7% of controls. The average values of oxidative stress were expressed for the whole group. The average follow up was 199.3;9.2 days in the Robuvit group and 202.2;5.5 in the control group with a minimum of 6 months. Considering variations in oxidative stress, there was no significant average change in controls, but a significant decrease from the initial values was observed in Robuvit subjects after 3 and 6 months. The CFS questionnaire variations in score indicated that there was a significant improvement for most symptoms after 3 and 6 months in the Robuvit group. Positive variations were also present in controls, indicating the positive effect of an increased attention to CFS. The improvement in signs/symptoms was significantly more valuable in subjects using the oak wood extract considering the main 8 symptoms and the accessory symptoms. Considering the BMIS variations, the totals for positive and negative items were significantly more favourable for Robuvit subjects. Overall mood evaluation in the oak wood extract group improved from an inclusion average of -6.93;2.1 to +4.32;2.6 at 6 months; in contrast it changed from -6.5;2.5 to -3.4;1.5 in controls. No side effects were observed during the supplementation with Robuvit. The compliance was optimal with 93% of the capsules correctly used. CONCLUSION: This promising pilot supplement registry study indicates a new opportunity of management for these difficult and often neglected patients. Correlation between oxidative stress and CFS have to be better explored.

ABSTRACT

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.

ABSTRACT

AIM: Mild, temporary hepatic failure (MTHF) may be completely asymptomatic or cause minimal signs and symptoms. This common clinical problem is very diffuse and, in case of repeated episodes may cause a chronic impairment in liver function. The aim of this registry was to evaluate the evolution of MTHF in subjects using Liverubin (a new standardized Silymarin preparation) over a 4-week period. METHODS: Patients with MTHF were observed in a registry study. In all subjects viral hepatitis markers were negative at inclusion. Different possible causes of MTHF had been considered, documented or excluded. The role of alcohol was mainly as a "facilitator" and not definitely determinant as a single factor in causing the MTHF episode. The registry included patients with MTHF characterized by: decreased albumin levels; increased total bilirubin; altered hepatic functions enzymes; increased oxidative stress. Two management groups were created: a. standard management (SM) only; b: SM and Liverubin; 25 Liverubin patients and 23 SM subjects completed the registry. The average follow-up period was 32.2;1.3 days in the supplement group and 32.1;2 days in controls. RESULTS: The distribution of symptoms and ultrasound results were comparable. Most symptoms observed at inclusion were disappeared or attenuated at 4 weeks in both groups. At inclusion, the values in the two groups were comparable. The increase in albumin levels was significantly (P<0.05 at 4 weeks) faster and the final values were higher in the Liverubin group. Total bilirubin was reduced in the supplement group better than in controls (P<0.05). Direct bilirubin values improved more in the supplement group at 4 weeks (P<0.05). The decrease of ALT-SGPT and AST-ASAT was more evident in the supplement group (P<0.05). Improvement in controls was more limited. Alkaline phosphatase value was normalized at 4 weeks in Liverubin patients; values decreased less in controls (P<0.05). Gamma GT decreased and were normal at 4 weeks with Liverubin. ESR was decreased in both groups (significantly more in the Liverubin group: P<0.05). There was a less important decrease in controls without normalization at 4 weeks. The white cell count was also better at 4 weeks in the supplement group; P<0.05). Plasma free radicals were significantly elevated in both groups at inclusion. A more significant decrease in the supplement group was observed at 4 weeks. Persisting, elevated values were seen in controls (P<0.05 in comparison with normal range). Platelets values improved in the Liverubin group (P<0.05) better than in controls. All other blood tests values (including hematocrit, renal function tests) were within the normal range at inclusion and at 4 weeks in both groups. Hepatitis markers were negative at inclusion and at 4 weeks. Compliance. Ninety-six percent of the Liverubin capsules were correctly used. Safety and tolerability were optimal (no side effect was registered). CONCLUSION: In conclusion, data from this pilot, registry study indicate a significant activity of Liverubin associated with a very good safety profile, in patients with temporary hepatic failure. The recovery of hepatic function is faster and more effective with Liverubin compared to the best "standard" management.

ABSTRACT

AIM: The aim of this registry study was to evaluate the effects of Pycnogenol® (French pine bark extract) on improving physical fitness (PF) in normal individuals using the Army Physical Fitness Test (APFT). The study evaluated the efficacy of Pycnogenol, used as a supplement, in improving training, exercise, recovery and oxidative stress. METHODS: The study was divided into 2 parts. In PART 1 (Pycnogenol 100 mg/day), the APFT was used to assess an improvement in PF during an 8-week preparation and training program. In PART 2 (Pycnogenol 150 mg/day), the study evaluated the effects of Pycnogenol supplementation in athletes in training for a triathlon. RESULTS: PART 1. There was a significant improvement in both males and females in the 2-mile running time within both groups, but the group using Pycnogenol (74 subjects) performed statistically better than controls (73 subjects). The number of push-ups was improved, with Pycnogenol subjects performing better. Sit-ups also improved in the Pycnogenol group. Oxidative stress decreased with exercise in all subjects; in Pycnogenol subjects the results were significantly better. PART 2. In the Pycnogenol group 32 males (37.9; SD 4.4 years) were compliant with the training plan at 4 weeks. In controls there were 22 subjects (37.2;3.5) completing the training plans. The swimming, biking and running scores in both groups improved with training. The Pycnogenol group had more benefits in comparison with controls. The total triathlon time was 89 min 44 s in Pycnogenol subjects versus 96 min 5 s in controls. Controls improved their performing time on average 4.6 minutes in comparison with an improvement of 10.8 minutes in Pycnogenol subjects. A significant decrease in cramps and running and post-running pain was seen in the Pycnogenol group; there were no significant differences in controls. There was an important, significant post-triathlon decrease of PFR one hour after the end of the triathlon with an average of -26.7, whereas PFR in controls increased. In Pycnogenol subjects there was a lower increase on oxidative stress with a faster recovery to almost normal levels (<330 for these subjects). These variations in PFR values were interpreted as a faster metabolic recovery in subjects using Pycnogenol. CONCLUSION: This study opens an interesting new application of the natural supplementation with Pycnogenol that, with proper hydration, good training and nutritional attention may improve training and performances both in normal subjects and in semi-professional athletes performing at high levels in difficult, high-stress sports such as the triathlon.

ABSTRACT

This open, controlled study evaluated the effects of 6 month supplementation with Pycnogenol® maritime pine bark extract on health risk factors in subjects with metabolic syndrome. Pycnogenol® was used with the aim of improving risk factors associated with metabolic syndrome, central obesity, elevated triglycerides (TG), low HDL cholesterol, high blood pressure and fasting blood glucose. Sixty-four subjects (range 45-55 years) presenting with all five risk factors of metabolic syndrome were included, and Pycnogenol® was administered for 6 months. A group of 66 equivalent subjects were followed up as controls. In the 6-month study Pycnogenol® supplementation 150 mg/day decreased waist circumference, TG levels, blood pressure and increased the HDL cholesterol levels in subjects. Pycnogenol lowered fasting glucose from baseline 123 ± 8.6 mg/dl to 106.4 ± 5.3 after 3 months and to 105.3 ± 2.5 at the end of the study (p < 0.05 vs controls). Men's waist circumference decreased with Pycnogenol from 106.2 ± 2.2 cm to 98.8 ± 2.3 cm and to 98.3 ± 2.1 after 3 and 6 months. Women's waist decreased from 90.9 ± 1.6 cm to 84.6 ± 2.1 cm and to 83.6 ± 2.2 cm after 3 and 6 months. Both genders waist circumference reduction was significant as compared to controls at both time points. In addition, plasma free radicals decrease in the Pycnogenol group was more effective than in the control group (-34.6%; p < 0.05). In conclusion, this study indicates a role for Pycnogenol® for improving health risk factors in subjects with metabolic syndrome.

ABSTRACT

BACKGROUND: In the present study, the improvement of diabetic microangiopathy and retinopathy was evaluated in 38 diabetic patients treated with a novel curcumin phospholipids delivery form (Meriva®). METHODS: Diabetes was diagnosed at least 5 years before inclusion and all patients had signs of retinal oedema and of peripheral microangiopathy. Meriva® was administered at the dosage of 2 tablets/day (each tablet containing 500 mg Meriva® corresponding to 100 mg curcumin) for a period of at least 4 weeks in addition to the standard management plan, while a comparable group of subjects (n = 39) followed the standard management plan alone. RESULTS: All subjects (treatment and controls) completed the follow-up period, there were no dropouts and Meriva® showed an optimal tolerability. At 4 weeks, microcirculatory and clinical evaluations indicated an improvement of microangiopathy. In terms of peripheral microangiopathy, in the Meriva® group, there was a significant improvement in the venoarteriolar response (p<0.05) and a decrease in the score of peripheral oedema (p<0.05), a sign typically associated with the failure of the venoarteriolar response. At the retinal level, high-resolution, duplex scanning, used to measure retinal flow, showed improvements in the Meriva® treated patients. The evaluation of retinal oedema (Steigerwalt's scale) showed an improvement associated with improved visual acuity (Snellen scale). There were no clinical or microcirculatory effects in controls. CONCLUSION: These preliminary observations, indicate the value of curcumin, when administered in a bioavailable form as with Meriva®, in the management of diabetic microangiopathy and retinopathy.

ABSTRACT

AIM: Intermittent claudication (IC) in peripheral vascular disease is characterized by lower limb pain appearing on effort. Treatment with PGE1 has been successfully used to manage IC patients. This registry has evaluated safety and costs of PGE1 in the management of IC. METHODS: In this study a long-term treatment protocol (LTP), a short-term protocol (STP) and an outpatient (OP), "on-demand" treatment have been compared. A treadmill effort test has been used to evaluate walking distance. The follow up for these three protocols was 40 weeks. PGE1 treatment was associated to a risk reduction plan and to an exercise program. RESULTS: The final analysis has included 252 LTP patients, 223 STP patients and 284 OP patients (total 659 valid cases). A group of 171 comparable patients not treated with PGE1 was used for a parallel comparison. Cardiovascular mortality and morbidity has been evaluated in 731 PGE1 patients completing 24 months of follow up. All protocols have been well tolerated. No side effects were observed. The lower cost has been observed for OP patients. In the long term, mortality and morbidity were lower in patients treated with PGE1 in comparison with patients not treated with PGE1. CONCLUSION: Considering costs and results (increase in walking distance) and improvement in Karnofsky scale the STP plan appears to be better than LTP for IC patients. The OP, "on-demand" treatment offers further improvements. This last treatment plan is simpler; the plan allows better timing for exercise. The treatment can be used even in non-specialized centers.
