ABSTRACT

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.

ABSTRACT

OBJECTIVE: The objective of this clinical study is to evaluate possible interactions between antiplatelet agents, anticoagulants, thyroid hormone replacement therapy and a formulation of curcumin (Meriva®) that resulted effective for the complementary treatment of osteoarthritis. PATIENTS AND METHODS: Interaction between antiplatelet agents and Meriva® was evaluated by measuring anti-platelet activity with the in-vivo bleeding-time (BT) in patients assuming acetylsalicylic acid or ticlopidine or clopidogrel from at least 2 years. The BT was evaluated before and after 10 days of supplementation with Meriva®. The interaction between anticoagulants and Meriva® was evaluated in patients using warfarin or dabigatran for previous venous thrombosis. The INR level was evaluated before and after 10 days of supplementation with the curcumin formulation. Thyroid function tests in hypothyroid patients using LT4 replacement therapy (Eutirox®) were evaluated before and after 15 days of supplementation with Meriva®. Similarly, levels of glycemia and glycated hemoglobin were evaluated in diabetic patients in treatment with metformin, before and after 10 days of supplementation with the studied product. RESULTS: After 10 days of supplementation with Meriva® the average BT value was not significantly different for patients assuming acetylsalicylic acid, ticlopidine or clopidogrel at standard dosages. Similarly, after 10 days of Meriva® treatment, the INR level in the two groups of patients assuming warfarin or dabigatran was not statistically different from that observed at baseline. In the analyzed patients assuming LT4 or metformin, no interactions between the therapy and Meriva® were observed. CONCLUSIONS: Results from this non-interaction clinical study suggest that Meriva® does not interfere with the antiplatelet activity of the most common antiplatelet agents nor alters the INR values in stable patients assuming warfarin or dabigatran. Similarly, dosages of LT4 or metformin do not need to be adjusted in case of complementary treatment with Meriva®.

ABSTRACT

OBJECTIVE: Supplementation with Mirtogenol® improves the retinal microcirculation and reduces intraocular pressure (IOP) in ocular hypertension, when administrated either alone or in association with an ophthalmic solution (latanoprost). In this study, microcirculatory parameters (perfusion of the circle of Zinn-Haller and retinal circulation) and oxidative stress were tested to assess the effects of Mirtogenol® plus traditional antihypertensive drugs in patients with elevated IOP. PATIENTS AND METHODS: 88 otherwise healthy patients with increased IOP were followed-up in a supplement registry for 12 weeks. Three groups received; (a) dorzolamide-timolol plus Mirtogenol®; (b) latanoprost drops plus Mirtogenol® or (c) latanoprost only. Oral supplementation consisted of two tablets/day of Mirtogenol® (80 mg of bilberry extract, Mirtoselect® plus 40 mg of Pycnogenol®). IOP, retinal blood flow, perfusion of the circle of Zinn-Haller, and oxidative stress were measured during the registry period. RESULTS: The three study groups were comparable; IOP and ocular blood flow velocity at inclusion were also comparable. Over the study period the decrease in IOP and the improvements in retinal microcirculation were statistically significant for all management groups, with a marginally more evident benefit in Mirtogenol®+latanosprost-treated patients. At 12 weeks, the altered perfusion at the circle of Zinn-Haller was improved in all groups; patients using Mirtogenol® showed a better perfusional pattern compared with subjects using only latanoprost. A reduction in oxidative stress was observed in supplemented subjects at the end of the study period; no significant change was seen in non-supplemented patients. All managements were well-tolerated without side effects. CONCLUSIONS: Supplementation with Mirtogenol®, in addition to local ophthalmic treatments, is safe and may contribute as a supplementary management to reach a normal IOP and ocular microcirculatory parameters.

ABSTRACT

OBJECTIVE: Oncological treatments are associated with toxicities that may decrease compliance to treatment in most genitourinary cancer patients. Supplementation with pharmaceutical-standardized supplement may be a supplementary method to control the side effects after chemo- and radiotherapy and the increased oxidative stress associated to treatments. This registry study evaluated a natural combination of supplements containing curcumin, cordyceps, and astaxanthin (Oncotris™) used as supplementary management in genitourinary cancer patients who had undergone oncological therapy. PATIENTS AND METHODS: Patients with genitourinary cancers (prostate or bladder malignancies) who had undergone and completed cancer treatments (radiotherapy, chemotherapy or intravesical immunotherapy with increased oxidative stress and residual symptoms) were recruited in this registry, supplement study. Registry subjects (n = 61) freely decided to follow either a standard management (SM) (control group = 35) or SM plus oral daily supplementation (supplement group = 26). Evaluation of severity of treatment-related residual side effects, blood count test, prostate-specific antigen (PSA) test and plasma free radicals (oxidative stress) were performed at inclusion and at the end of the observational period (6 weeks). RESULTS: Two patients dropped out during the registry. Therefore, the analysis included 59 participants: 26 individuals in the supplementation group and 33 in the control group. In the supplement group, the intensity of signs and symptoms (treatment-related) and residual side effects significantly decreased at 6 weeks: minimal changes were observed in controls. Supplementation with Oncotris™ was associated with a significant improvement in blood cell count and with a decreased level of plasmatic PSA and oxidative stress. CONCLUSIONS: Naturally-derived supplements, specifically Oncotris™ (patent pending), could support the body to overcome the treatment-related toxicities - and the relative oxidative stress in cancer patients.

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: Impairment of the peripheral microcirculation in diabetic patients often leads to severe complications in the lower extremities, such as foot infections and ulcerations. In this study, a novel aescin-based formulation has been evaluated as a potential approach to prevent skin breaks and ulcerations by improving the peripheral microcirculation and skin hydration. PATIENTS AND METHODS: In this registry study, 63 patients with moderate diabetic microangiopathy were recruited. Informed participants freely decided to follow either a standard management (SM) to prevent diabetic foot diseases (n = 31) or SM associated with topical application of the aescin-based cream (n = 32). Peripheral microcirculatory parameters such as resting skin flux, venoarteriolar response and transcutaneous gas tension were evaluated at inclusion and after 8 weeks. In addition, several skin parameters of the foot area, such as integrity (as number of skin breaks/patients), hydration and content of dead cells were assessed at the defined observational study periods. RESULTS: Improvements in cutaneous peripheral microcirculation parameters were observed at 8 weeks in both groups; however, a remarkable and significant beneficial effect resulted to be exerted by the aescin-based cream treatment. In fact, the microcirculatory parameters evaluated significantly improved in the standard management + aescin-based cream group, compared with baseline and with the standard management group. Similar findings were reported for skin parameters of the foot area. CONCLUSIONS: The topical formulation containing aescin could represent a valid approach to manage skin wounds and prevent skin ulcerations in patients affected by moderate diabetic microangiopathy.

ABSTRACT

Mild, temporary hepatic failure (MTHF) after chemotherapy is a common clinical problem; in case of repeated episodes MTHF may cause chronic impairment. This registry has evaluated post- chemotherapy (PC)-MTHF in subjects using Liverubin (standardized Silymarin) for 8 weeks (3 capsules/day). METHODS: PC-MTHF was evaluated in a registry study. Hepatitis markers were negative at inclusion and at end-registry. In the final registry there were results concerning 18 Liverubin-supplemented patients and 19 controls completing the 8-week period. Signs/symptoms. The distribution of the most common symptoms and signs with ultrasound scans were comparable. Symptoms were mostly minimal or subclinical. Most symptoms observed at inclusion were completely disappeared or greatly attenuated after 8 weeks. The improvement produced by Liverubin induced a better and faster disappearance of symptoms. The results of the blood tests (at inclusion and at 8 weeks showed the increase in albumin, significantly (P<0.05) faster with the final values higher in the supplement group. Total bilirubin was reduced with the supplement better than in controls (P<0.05). Direct bilirubin values improved more in the supplement (P<0.05) group. The decrease in SGPT and AST-ASAT was more evident with the supplement (P<0.05). Improvement in controls was more limited. Alkaline phosphatase was significantly lower (than in controls) with Liverubin at 8 weeks (p<0.05). Gamma GT also decreased more and faster with the supplement. The ESR (erythrocytes sedimentation rate) was decreased in both groups, more in the Liverubin group (P<0.05). There was a more limited decrease in controls with persisting higher values at 8 weeks. The white cell count was also better at 3 months (with a larger decrease with the supplement; P<0.05). Oxidative stress. Plasma free radicals (PFR) were elevated in both groups at inclusion. A more significant decrease in the supplement group was observed at 8 weeks. Persisting elevation in values was seen in controls (P<0.05). Platelets values improved better with Liverubin (P<0.05). Safety and tolerability were optimal (no side effect was registered). In conclusion, results from this pilot registry indicate a significant activity of Liverubin associated with a very good safety profile, in patients with post-chemotherapy hepatic failure. The recovery of hepatic function is faster and more effective with Liverubin in comparison with the best "standard" management.

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

The aim of this registry study was the evaluation of possible benefits of a supplement including CoenzymeQ10 and a grape seed combination (MiraQule C, Alchem) in stable, moderate, heart failure patients. RESULTS: The mean age of the 18 supplemented patients was 60.1;2 years (the age of the 22 controls was 61.1;2.2). The two groups were comparable. There were no dropouts in the two groups. In the 8 weeks of the registry, all supplemented patients remained in the NYHA class while 7 out of 22 in controls increased the level of heart failure passing into Class III. Systolic- diastolic pressure, heart rate, respiratory rate were minimally (non significantly lowered) with the supplement without differences controls. Ultrasound-derived ejection fraction was increased by supplementation (median of 2.7%) in the CoQ10 group (p<0.05) while there were minimal, non- significant differences in controls. Walking distance on treadmill was also significantly increased with the supplement (p<0.05) and only marginally in controls. The microcirculation (laser Doppler parameters and transcutaneous PO2, PCO2) improved significantly in the MQ-C group (p<0.05) and only marginally in controls. Oxidative stress was significantly decreased (p<0.05) with the CoQ10 preparation while there were minimal. Non-significant changes were observed in in controls. Tolerability and compliance were optimal (with more than 95% of the capsules correctly used). In conclusion in this supplement registry Miraqule-C seem to help patients with moderate heart failure and should be considered for larger studies.

ABSTRACT

Mild, temporary hepatic failure (MTHF) is a common clinical problem; in case of repeated episodes MTHF may cause chronic liver impairment. This registry has evaluated MTHF in subjects using Liverubin (standardized Silymarin) for 8 weeks. METHODS: MTHF was evaluated in a registry study. In all subjects viral hepatitis markers were negative at inclusion. Different possible causes of MTHF had been considered. In these subjects alcohol was not a main factor. The registry included MTHF patients with decreased albumin levels, increased total bilirubin, altered hepatic function enzymes, increased oxidative stress. Two management groups were created: a standard management (SM) group and a SM+Liverubin group; 32 Liverubin patients and 33 SM subjects completed the registry. Liverubin was used at the dosage of two tablets (each equivalent to 140 mg) daily. RESULTS: Distribution of symptoms, blood test values and ultrasound results were comparable. Symptoms observed at inclusion disappeared at 3 months in both groups. The increase in albumin levels was significantly (P<0.05 at 4 weeks) faster and the final blood tests improved more with Liverubin. Total bilirubin was reduced with the supplement (better than in controls; P<0.05). Direct bilirubin values improved more in the supplement group at 3 months (P<0.05). The decrease of SGPT and AST- ASAT was more evident in the supplement group (P<0.05). Alkaline phosphatase value was normalized at in Liverubin patients; values decreased less in controls (P<0.05). Gamma GT decreased more with Liverubin. ESR was decreased in both groups (significantly more with Liverubin: P<0.05). There was a less important decrease in controls at 3 months. The white cell count was also better with the supplement group; P<0.05). Plasma free radicals - significantly elevated in both groups at inclusion - decreased more with the supplement at 3 months. All other blood tests (including hematocrit, renal function tests) were within the normal range at inclusion and at 3 months in both groups. Hepatitis markers were negative at inclusion and at end-registry. 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 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

OBJECTIVE: Cranberry extracts have been tested as a nutritional supplementation in the prevention of recurrent lower-urinary tract infections (R-UTIs), with mixed results. This pilot, registry study evaluates the prophylactic effects of oral supplementation with a new well-standardized cranberry extract in patients with R-UTI, over a 2-month follow-up. PATIENTS AND METHODS: All subjects were suggested to take one capsule containing a cranberry extract (Anthocran™) for 60 days and were also given lifestyle advice. Clinical outcomes were compared between patients on cranberry extracts and those who don't take this supplementation. RESULTS: In total, 22 subjects completed the study in each of the two groups. In the cranberry group, the reduction in the frequency of UTI episodes during the study period compared with the two months before the inclusion was 73.3% (p < 0.05). This figure was 15.4% in the control group (p < 0.05; p = 0.012 vs cranberry group). Seven (31.8%) subjects in the cranberry group were symptom-free; no patient was symptom-free in the control group (p < 0.05). The mean duration of UTI episodes was 2.5 ± 1.3 days in the cranberry group, compared with 3.6 ± 1.7 days in subjects not on cranberry (p < 0.05). Three subjects (13.6%) in the cranberry group and 8 (36.3%) in the control group required medical consultation for UTI symptoms (p < 0.05). Urine evaluation was completely negative in 20/22 subjects in the Cranberry group (90.9%) and in 11 control subjects (50.0%; p < 0.005). No adverse events were observed. CONCLUSIONS: These preliminary results, obtained in a field-practice setting, indicates the effectiveness and safety of a well-standardized cranberry extract in the prevention of R-UTI.

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 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

OBJECTIVE: This study evaluates the efficacy of Beanblock®, a standardized extract of Phaseolus vulgaris L., on weight control in healthy overweight subjects on a weight management plan that combined lifestyle and dietary advice. PATIENTS AND METHODS: Sixty overweight (BMI 25-30 kg/m2) healthy subjects were enroled. All subjects were instructed to follow a weight management plan, accompanied by dietary advice. Thirty subjects used Beanblock® for at least 12 weeks (50 mg tablets, two times daily). The remaining 30 subjects did not receive any supplementation (management-only). The main endpoints were changes in body weight and waist circumference, with plasmatic oxidative stress, satiey and appetite being also evaluated. RESULTS: At week 12, the supplementation with Beanblock® was associated with a reduction in body weight (from 82.8 ± 9.1 kg to 78.8 ± 8.9 kg; p < 0.0001) and a decrease of waist circumference from 94.4 ± 10.3 cm to 88.2 ± 10.0 cm (p < 0.0001). Conversely, only marginal changes were observed in the control group. Oxidative stress was also significantly decreased with Beanblock® (from 380.4 ± 14.8 to 340.7 ± 14.8 Carr Units; p < 0.0001). Satiety and appetite improved in the supplement group. No side effects were observed and compliance was optimal. CONCLUSIONS: Beanblock®, in association with a health management plan, was useful for weight control in mildly overweight healthy subjects.

ABSTRACT

AIM: The aim of this supplement registry was to evaluate the efficacy of the Pycnogenol® in improving cochlear flow and symptoms in a 6-month follow-up for patients with Meniere's disease (MD), tinnitus and cochlear hypoperfusion. METHODS: Main signs/symptoms were considered: Spontaneous vertigo, positional vertigo, hearing loss, tinnitus, pressure in the ear, unsteady gait, associated clinical problems, alterations in daily life. All subjects were managed with the best available management (BM); one group used the supplement Pycnogenol (150 mg/day). Cochlear flow and tinnitus were also evaluated. Out of 120 patients incuded in the registry, 55 used Pycnogenol and 52 (controls) were managed only with BM. RESULTS: There was a more significant improvement in all registry items at 3 and 6 months in the Pycnogenol group (P<0.05). The number of lost working days was lower in the Pycnogenol group. At 3 months, 45.4% of subjects using Pycnogenol were completely asymptomatic in comparison with 23.07% of controls. At 6 months 87.3% of the Pycnogenol subjects were asymptomatic compared with 34.6% of controls. Cochlear flow velocity was significantly better (higher flow, higher diastolic component) in the Pycnogenol group (P<0.05). The subjective tinnitus scale decreased in both groups (P<0.05); the decrease was more significant in Pycnogenol subjects (P<0.05) at 3 and 6 months. CONCLUSION: Symptoms of Meniere's disease, flow at cochlear level and tinnitus improved in Pycnogenol subjects in comparison with best management.

ABSTRACT

This study evaluated the stretching and dilatation of venous segments ex vivo in subjects with primary varicose veins in comparison with comparable segments from subjects that used the supplement Pycnogenol (150 mg/d) for 3 months before surgery. Subjects with varicose veins and chronic venous insufficiency voluntarily used Pycnogenol for a period of at least 3 months. The segments of veins removed with surgery (in 30 subjects that had used Pycnogenol and in 10 comparable control subjects that had not used the supplement) were compared with normal, unused vein segments harvested for bypass grafting. The segments were suspended and a weight was attached to the distal part of the veins for 3 minutes and dilated with pressurized water. Digital images were recorded; the veins were measured before and after stretching to evaluate elongation. The manipulation of the vein segment was minimal. Tests were completed within 20 minutes after harvesting the veins. All segments were 4 cm long. The stretching test indicated a significantly higher level of passive elongation in control, varicose segments (2.29; 0.65 mm) in comparison with 1.39; 0.2 mm in vein segments from Pycnogenol-using patients. The dilation test showed an average higher dilation (2.19; 0.3 mm) in control varicose veins in comparison with varicose veins from Pycnogenol-using patients (1.32; 0.7 mm) (p < 0.05). Stretching and dilatation were lower in veins from Pycnogenol-using subjects (p < 0.05). The measurement of destretching and the recovery after dilatation indicated a better tone and recovery of the original size/shape in varicose segments from patients using Pycnogenol. Varicose segments had a more significant persistent dilatation and elongation in comparison with normal vein segments. Pycnogenol seems to decrease passive dilatation and stretching and gives vein walls a greater tonic recovery and elasticity that allows the vein to recover its original shape after dynamic stresses.

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

OBJECTIVE: Osteoarthritis (OA) is a major cause of physical disability and impaired quality of life. Non-steroidal anti-inflammatory drugs are the most used treatment for OA, but they are frequently associated to adverse events. Alternative therapies are under investigation for the treatment of OA. Meriva® is a lecithin delivery form of curcumin, a powerful promoter of anti-oxidant response studied in a number of conditions related to chronic inflammation and pain. PATIENTS AND METHODS: This 4-month observational study, conducted in a 'real-life' scenario, compares the association of Meriva and glucosamine (n=63) with chondroitin sulphate+glucosamine (n=61) in 124 patients with grade 1-2 OA of the knee. RESULTS: Patients treated with Meriva+glucosamine had significantly higher Karnofsky Index and WOMAC score (both in the physical and emotional domains), compared to those in the chondroitin+glucosamine group. Noteworthy, the walking distance at the treadmill test after 1 month was also significantly higher in the meriva+glucosamine group; this advantage was sustained until the end of the study. Although the need for concomitant drugs and medical attention decreased in both groups, this reduction was more evident for patients treated with Meriva+glucosamine. CONCLUSIONS: Taken together, the results of this study shows that the 4-month administration of the association of Meriva and glucosamine can result in a faster onset of action and improved outcomes than the administration of an association of chondroitin sulphate and glucosamine in patients with OA.

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.
