RESUMO

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.

RESUMO

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®.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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

RESUMO

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.

RESUMO

AIM: Post-thrombotic syndrome is a common complication following deep vein thrombosis. The aim of this twelve month registry study was to compare the efficacy of compression stockings and per oral administration of Pycnogenol® standardized pine bark extract on the severity and incidence of post thrombotic syndrome signs and symptoms. METHODS: One hundred fifty-six patients with a single, major episode of proximal deep vein thrombosis (DVT) were assigned to one of three groups receiving treatment with either compression stockings (group 1), Pycnogenol® (group 2) or the combination of both (group 3) over an investigational period of one year. The study evaluated treatment on edema using a scoring system, the ankle circumference, and the limb volume as ratio to the healthy contralateral limb. RESULTS: Two new incidents of DVT occurred in the group of 55 patients wearing compression stockings between the third and sixth months, whereas no DVT cases occurred in the two other groups which took Pycnogenol®. The edema symptom score was gradually decreased in all three groups during the one year treatment period. Pycnogenol® was significantly more effective from six months onwards than compression stockings for relieving edema symptoms (P<0.05). Symptoms were more effectively reduced with the combination of Pycnogenol® and compression stockings than with the individual regimen alone (P<0.05). Limb volume and ankle circumference were likewise more effectively reduced with Pycnogenol® plus stockings than with compression stockings alone after six months. Ambulatory venous pressure progressively decreased in all three groups after twelve months treatment as compared to baseline. Compression stockings and Pycnogenol® were of comparable efficacy, there were no significant differences of ambulatory venous pressure between groups following twelve months treatment. Laser Doppler flowmetry at the dorsum of feet showed improved micro-circulation which was further demonstrated by increased pO2 and decreased pCO2. Importantly, none of the patients developed ulcerations during the observational period. CONCLUSION: This study suggests that Pycnogenol® may have significant long-term protective efficacy for individuals following a thrombotic event. Moreover, Pycnogenol® appears to be at least as effective for post-thrombosis management as compression stockings, while the combination of both is superior. An important aspect is the patient compliance which was found to be much better in the Pycnogenol® group with two drop-outs due to non-medical reasons, whereas in the compression stockings group eighteen patients were lost to follow-up because wearing stockings at higher temperatures is bothersome.

RESUMO

AIM: The aim of the present study was to evaluate the improvement of diabetic microangiopathy in patients suffering from this condition since at least five years, and whose disease was managed without insulin. METHODS: Curcumin, the orange pigment of turmeric, has recently received increasing attention because of its antioxidant properties, mediated by both direct oxygen radical quenching and by induction of anti-oxidant responses via Nrf2 activation. This aspect, combined with the beneficial effects on endothelial function and on tissue and plasma inflammatory status, makes curcumin potentially useful for the management of diabetic microangiopathy. To further evaluate this, Meriva, a lecithinized formulation of curcumin, was administered at the dosage of two tablets/day (1 g Meriva/day) to 25 diabetic patients for four weeks. A comparable group of subjects followed the best possible management for this type of patients. RESULTS: All subjects in the treatment and control group completed the follow-up period; there were no dropouts. In the treatment group, at four weeks, microcirculatory and clinical evaluations indicated a decrease in skin flux (P<0.05) at the surface of the foot, a finding diagnostic of an improvement in microangiopathy, the flux being generally increased in patients affected by diabetic microangiopathy. Also, a significant decrease in the edema score (P<0.05) and a corresponding improvement in the venoarteriolar response (P<0.05) were observed. The PO2 increased at four weeks (P<0.05), as expected from a better oxygen diffusion into the skin due to the decreased edema. These findings were present in all subjects using Meriva, while no clinical or microcirculatory effects were observed in the control group. CONCLUSION: Meriva was, in general, well tolerated, and these preliminary findings suggest the usefulness of this curcumin formulation for the management of diabetic microangiopathy, opening a window of opportunities to be evaluated in more prolonged and larger studies. The molecular mechanisms involved in the beneficial effects of curcumin on microcirculation and edema are also worth investigation.

RESUMO

AIM: The aim of this study was to evaluate the efficacy of Pycnogenol® standardized pine bark extract for alleviation of signs and symptoms associated with menopausal transition. METHODS: Pycnogenol® was used by 38 women as daily supplement in a dosage of 100 mg over an eight week period and menopausal symptoms were evaluated by means of a scoring system, based on a total number of 33 common signs and symptoms. A parallel control group of 32 comparable women was also followed up for the same period. Pycnogenol® was well tolerated, no side effects were reported and the compliance was very good with 98.6% of tablets used as prescribed. A range of 33 menopausal symptoms were evaluated using a scoring system with values ranging from zero (absent) to maximum 4 (very serious). RESULTS: A subset of six most common symptoms comprising hot flushes, night sweats, mood swings, irregular periods, loss of libido and vaginal dryness showed a decrease from average 2.67/4 to 1.45/4 after 8 weeks supplementation with Pycnogenol®. The control group of women showed no change from initial average 2.72/4 to 2.73/4 after eight weeks. The improvement of symptoms was statistical significant compared to the control group. Further symptoms related to fatigue, sleeping disorders, concentration and memory problems, dizziness, depression and irritability all improved significantly with Pycnogenol® compared to baseline values but did not reach statistical significance compared to the control group of women. The sensation of pain related to headaches, breast pain, the feeling of "electric shocks", tingling extremities, burning tongue and itchy skin all improved significantly after intake of Pycnogenol® for eight weeks compared to baseline. Specifically the sensation of "electric shocks" and digestive problems improved significantly with Pycnogenol® as compared to women in the control group. The presence of elevated oxidative stress in women was investigated measuring capillary blood plasma free radicals. Oxidative stress was significantly lowered after four weeks (P<0.05) and eight weeks (P<0.022) in the Pycnogenol® group while no significant changes were observed in the control group at any time. CONCLUSION: Pycnogenol® significantly contributed to reduce signs and symptoms associated with menopausal transitions in women investigated in this study. Furthermore, Pycnogenol® improved the quality of life of most women and these benefits may be at least in part attributed to decreased oxidative stress levels.
