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

Nutrition in fetal and postnatal life can influence the development of several biological systems, with permanent effects in adult life. The aim of this work was to investigate in dairy sheep whether diets rich in starch or fiber during intrauterine life (75 d before lambing) and postnatal life (from weaning to first pregnancy; growth phase) program glucose and insulin metabolism in the female offspring during their first pregnancy. Starting from intrauterine life, 20 nulliparous Sarda ewes were exposed to 4 dietary regimens (n = 5 per group) based on different dietary carbohydrates during their intrauterine life and their subsequent growth phase: (1) the fiber (FI) diet during both intrauterine and growth life, (2) the starch (ST) diet during both intrauterine and growth life, (3) the FI diet in intrauterine life followed by the ST diet in the growth phase, and (4) the ST diet in intrauterine life followed by the FI diet in the growth phase. After the end of the growth phase, all growing ewes were fed the same diet and naturally mated. When ewes were pregnant, on average at 124 ± 2 d of gestation they were challenged with an intravenous glucose tolerance test, and peripheral concentrations of glucose and insulin were determined. Basal insulin concentrations were higher in ewes exposed to the ST diet (0.97 µg/L) than in ewes exposed to the FI diet (0.52 µg/L) in intrauterine life. After glucose infusion, glucose and insulin concentrations were not affected by intrauterine diet. Insulin resistance, determined by the homeostasis model assessment, was affected by the intrauterine × growth phases interaction. Insulin sensitivity, assessed by the quantitative insulin check index, was lower in ewes exposed to the ST diet than in those exposed to the FI diet in intrauterine life (ST = 0.28; FI = 0.30). Diet in growth life had no effect on glucose and insulin metabolism. In conclusion, starchy diets offered during intrauterine life but not during postnatal life increased basal insulin level and lowered insulin sensitivity during the first pregnancy. Nutritional strategies of metabolic programming should consider that exposure to starchy diets in late fetal life might favor the programming of dietary nutrient partitioning toward organs with high requirements, such as the gravid uterus or the mammary gland.

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

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.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: Bacterial infections are the leading causes of morbidity and mortality in haematologic patients with chemotherapy-induced neutropenia. The only strategy shown to be effective in reducing febrile neutropenia incidence is fluoroquinolone prophylaxis, but the safety of this class of drugs in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD-), the most common human enzyme defect, is still controversial because of the claimed association with acute haemolytic anaemia. METHODS: We retrospectively analysed 242 patients treated with 628 intensive chemotherapy courses. Of these, 59 patients were with G6PD-. All patients underwent fluoroquinolone prophylaxis and were transfused according to our single-unit transfusion policy. The principal endpoint was the incidence of acute haemolytic anaemia. Secondary endpoints included the incidence of febrile neutropenia, microbiologically and clinically documented infection (MDI and CDI) and the incidence of Gram-positive or Gram-negative infections. RESULTS AND DISCUSSIONS: No episode of acute haemolytic anaemia was observed in the entire cohort. The incidence of MDI and CDI was similar, but the incidence of invasive fungal disease (IFD; P<.0001, HR 11.4, 95%CI 3.5-37.05) and Candida sepsis (P=.008, HR 37, 95%CI 2.01-680.9) was higher in patients with G6PD-. Interestingly, we observed a reduced incidence of febrile neutropenia in patients with G6PD- (P=.01, HR 0.46, 95%CI 0.25-0.8). WHAT IS NEW AND CONCLUSIONS: Our data suggest that fluoroquinolone prophylaxis in patients with G6PD-, treated with intensive chemotherapy, is feasible and safe. Our findings on the incidence of IFD and febrile neutropenia suggest that G6PD may be important in susceptibility to opportunistic pathogens and host response in neutropenic patients.

RESUMO

OBJECTIVE: Several studies have investigated the role of cranberry extract in the prevention of recurrent urinary tract infections (UTIs), on different selected subpopulations at increased risk of UTI. In this registry, we tested the prophylactic effects of an oral supplementation containing a highly standardized cranberry extract (Anthocran®) in young subjects with a previous history of recurrent UTIs, over a 2-months follow-up. PATIENTS AND METHODS: 36 otherwise healthy subjects in juvenile age (between 12 and 18 years of age) suffering by recurrent UTIs were enrolled. Participants received either a standard management (SM) (control group, n=17) or SM associated with an oral daily supplementation (supplementation group, n=19). Oral supplementation consisted in one capsule containing 120 mg of cranberry extract (Anthocran®), standardized to 36 mg proanthocyanidins, for 60 days. The effectiveness in the prevention of UTIs was determined by: the number of UTIs evaluated two months before the inclusion in the registry and during the supplementation period; the number of symptom-free subjects during the registry period. Safety considerations and measurement of adherence to treatment were also performed. RESULTS: The two groups were comparable for age, gender distribution, the days of follow-up and also for the number of UTIs before inclusion. The mean number of UTIs observed during the registry in the supplemented group (0.31±0.2) was significantly lower compared to the control group (2.3±1.3) and to the mean number of UTIs assessed before inclusion (1.74±1.1) (p-value = 0.0001 for both). Moreover, 63.1% of supplemented subjects was symptom-free during the registry period, whereas 23.5% subjects were asymptomatic in the control group (p-value <0.05). CONCLUSIONS: This registry supplement study provides compelling evidence on the efficacy of an oral supplementation, based on a highly standardized cranberry extract (Anthocran®), as prophylaxis in young healthy subjects suffering by recurrent UTIs.

RESUMO

OBJECTIVE: Several experimental studies and clinical trials support the potential of Boswellia serrata extracts (BSE) for the treatment of various inflammatory diseases. The aim of this registry study was to assess the safety and the efficacy of a novel lecithin-based delivery form of Boswellia serrata extract (Casperome®) in the supportive management of osteo-muscular pain. PATIENTS AND METHODS: 52 healthy young rugby players with acute knee pain and inflammation were recruited. Informed participants freely decided to follow either a standard management (SM) to control joint pain (control group = 27) or SM associated with oral daily supplementation with Casperome® (supplement group =25). Parameters associated with osteo-muscular pain and inflammation, and measurements of joint health and functions were assessed at the inclusion and after a 4-week supplementation. RESULTS: A significant beneficial effect of Casperome® vs SM alone was observed for all the parameters evaluated, namely: local pain on effort; pain-free walking distance (treadmill test); minimal joint effusion; structural damage (joint, tendons, muscles) and intramuscular hematomas; thermal imaging of the anterior knee; Visual Analog Scale for Pain (VAS Pain); need for concomitant drugs and medical attention; measurement of inflammatory biomarkers. CONCLUSIONS: Our registry study suggests that Casperome® supplementation could represent an effective and safe, integrated approach for the treatment of osteo-muscular pain and inflammation.

RESUMO

OBJECTIVE: Recently, cranberry extracts have been tested as a nutritional supplementation in the prevention of lower urinary tract symptoms (LUTS) as well as recurrent urinary tract infections (UTIs) in subjects at risk, with mixed results. However, evidence of efficacy should be considered only for well-characterized and standardized products in a more selected study population. Moreover, the efficacy of these interventions in elderly must be further investigated. The aim of this pilot, registry study was to evaluate the prophylactic effects of an oral supplementation containing a highly concentrated and standardized cranberry extract reproducing the natural total profile of cranberry fruits, in elderly men with benign prostatic hyperplasia (BPH), suffering from recurrent UTIs, over a 2-months follow-up. PATIENTS AND METHODS: 43 men (age > 65 years) enrolled in this study freely decided to receive either a standard management (SM) only (n = 21) or SM associated with an oral supplementation (n = 23). Supplementation consisted in a daily administration of one capsule containing cranberry extract (Anthocran®) for 60 consecutive days. The clinical effectiveness in the prevention of UTIs was determined by the number of UTIs in the two months before the inclusion in the registry and during the supplementation period, and the number of symptom-free subjects during the registry period. Safety considerations were also performed. RESULTS: In the supplemented group, the mean number of UTI episodes reported during the registry (0.8 ± 0.5) significantly decreased compared with inclusion time (3.2 ± 1.3), p-value = 0.0001. No significant changes were observed in control, SM-only group. Importantly, the cranberry oral supplementation was superior over SM at reducing the mean number of UTIs (p-value = 0.0062). CONCLUSIONS: These results suggest that cranberry supplementation could be an effective and safe approach, within an SM program, for the prevention of recurrent UTIs in elderly men suffering from BPH avoiding some antibiotic treatments.

RESUMO

This registry study assessed the pharma-standard supplement FlexiQule (Boswellia extract in capsules) in the management of symptoms associated to osteoarthritis (OA) also managed with the 'standard management' (SM) in comparison with a group of patients managed only with SM. The 12- week registry included patients with symptomatic knee arthrosis. They were able to walk on a treadmill for a walking test and to complete the WOMAC questionnaire. RESULTS: 32 patients used the supplement and 34 acted as controls (SM). No safety problems were observed. At 12 weeks, the Karnofsky scale was significantly improved in both groups: the variation was higher (p<0.05) in the supplement group. 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). For social and emotional functions the decrease in score was also more evident in the supplement group (p<0.05). Both groups improved in pain-free and total walking distance at 12 weeks. Pain-free walking distance (treadmill) was higher (p<0.05) with the supplement (from 93.4;11.6 m to 271.3;19.3 m) than in controls (from 90.5;13.5 m to 158.3;22.3)(p<0.05). The improvement in total walking distance was also higher in the supplement group (p<0.05) (from 164.3;23.2 to 322.3;22.3 m) in comparison with the SM- only group ( from 158.3;18,4 to 240.2;19.3 m). The need for concomitant drugs and medical attention during the registry was reduced more in the supplement group (p<0.05). In conclusion the difference between SM and the Flexiqule+SM was in favor of the management with the supplement for all target measurements. The product is safe and well tolerated.

RESUMO

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.

RESUMO

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.

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: 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.

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

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

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.
