HR, 0-(beta-hydroxyethyl)-rutosides, in comparison with diosmin+hesperidin in chronic venous insufficiency and venous microangiopathy: an independent, prospective, comparative registry study.
The aim of this independent study was to investigate differences in efficacy between HR, (0-[beta-hydroxyethyl]-rutosides) and D+H (500 mg, diosmin+hesperidin) in patients with chronic venous insufficiency (CVI). A first group of 90 patients with severe venous hypertension (CVI, ankle swelling) were randomized into an HR or a D+H group. The HR group received oral HR (2 g/day, 8 weeks); the D+H group received a 500 mg tablet 3 times daily for 8 weeks. A second group of comparable patients was included in a registry following the same study format. Patients were openly included; the 2 treatments were administered with the same methods and procedures. Clinical conditions were comparable to those described in the randomized study. Patients treated for at least 8 weeks were included in the registry. A number of physicians (specialists or general practitioners) included patients when they considered that clinical conditions were compatible with using 1 of the 2 treatments on the basis of their personal evaluation and experience. When cases were compatible with the registry, the prescribing physician communicated the case. Patients were evaluated without interfering with the treatment. Main targets of evaluation were skin flux at rest (RF), strain-gauge-derived rate of ankle swelling (RAS), and analogue symptoms score (ASLS). Ninety subjects completed the study in the first group; 122 in the second, registry group (total of 212 patients). The first and second (registry) groups and the 2 treatment groups were comparable for age and sex distribution. The pooled mean age was 42 years (SD +/-5.5) in the HR group (46+62 patients) and 41.5 (SD +/-6) in the D+H group (44+60 patients). Considering pooled data there were no differences in microcirculatory parameters between the pooled treatment groups at inclusion. A significant decrease (p<0.05) in RF and RAS was observed in the HR group at 8 weeks. The decrease in resting skin flux and in capillary filtration was associated with a significant improvement in signs/symptoms (analogue scale line) from an average of 9.4 (range 3-10) to 3.3 (4-6) (p<0.05). Significantly smaller variations were observed in the D+H group. The decrease in RF was 47.6% in the HR group vs 15.7% in the D+H group. The decrease in RAS was 40.9% in the HR group vs 12.8% in the D+H group. The decrease in ASLS was 64.8% in the HR group vs 12.9% in the comparative group. In conclusion venous microangiopathy and edema were improved by the treatment with HR both in the randomized study and in the pooled analysis. The comparison with D+H indicates that HR is comparatively more effective both on microcirculatory parameters and on signs/symptoms of CVI.

HR, 0-(beta-hydroxyethyl)-rutosides; (Venoruton): rapid relief of signs/symptoms in chronic venous insufficiency and microangiopathy: a prospective, controlled study.
The aim of this independent study was to demonstrate the rapidity of the clinical action of HR 0-(beta-hydroxyethyl)-rutosides, Venoruton (Novartis Consumer Health) in patients with chronic venous insufficiency (CVI). Two groups of patients with venous hypertension and microangiopathy were treated with HR (1 or 2 g/day, for 8 weeks). Twelve patients (age 56.4; range 44-66; M:F = 6:6) were included in group 1 (1 g/day) (moderate CVI and microangiopathy); 10 patients (age 57.4; range 42-67; M:F = 5:5) in group 2 (2 g/day) with more severe CVI and microangiopathy. Average ambulatory venous pressure (AVP) was 58.6 (range 50-65) with a refilling time (RT) shorter than 10 seconds. There were no significant differences in AVP and RT between the 2 groups, but the duration of the disease was longer in group 2: 3.5 years (SD 2.0) in group 1 and 6.4 years (SD 3.3) in group 2. All included subjects completed the study and no dropouts were observed. In both dose groups there was a progressive decrease in laser Doppler resting flux (RF), indicating improvement in microangiopathy and a significant decrease in capillary filtration (RAS) associated with a significant improvement in analogue scale line score (ASLS) and edema. Although the effect in the 2 g dose group was more rapid on the microcirculatory parameters with a significant effect on RF and RAS after 4 days (effect of 1 g per day after 8 days and 6 days, respectively), there was no difference in the time to onset of a significant clinical improvement (ie, the ASLS and the edema score): 4 days in both groups. Venous microangiopathy and edema were improved by the treatment with HR within a few days. The effects were visible with both dosages, in both severity groups.

Venous ulcers: microcirculatory improvement and faster healing with local use of Pycnogenol.
Chronic venous insufficiency (CVI) causes a well-defined microangiopathy described as venous hypertensive microangiopathy (VHM) leading to venous ulcerations. VHM is mainly observed in the distal part of the leg, in the perimalleolar region. In VHM edema is the consequence of increased capillary pressure and reduced local clearance, and this affects local perfusion. The healing of venous ulcers is usually very slow. Many treatments are available, but there is still no standard. Oral Pycnogenol is effective in venous disease and particularly in controlling edema. The aim of this study was the evaluation of the local effects of Pycnogenol on ulcers healing associated with venous hypertension. The study lasted 6 weeks including 18 patients (16 completed the study) with venous ulcerations. The oral treatment with Pycnogenol was compared with a combination treatment including oral and local treatment. In subjects treated with the combination treatment (oral and local), venous ulcers healed better (there was a faster reduction in ulcerated area) in comparison with oral treatment only. According to this pilot study Pycnogenol appears to have an important role in local treatment of venous ulcers improving healing and signs/symptoms.

A plaster combining diclofenac and heparin: microcirculatory evaluation in 2 models of high-perfusion microangiopathy.
A medicated plaster containing diclofenac epolamine (DHEP) and heparin has been recently proposed for the treatment of local trauma (ie, ankle sprains) accompanied by a clinically significant edema and/or hematoma formation, based on the combined antiinflammatory, hemorheologic, and antiedema properties of diclofenac and heparin. The aim of this study was therefore to compare the effects of a combined DHEP/heparin and DHEP alone in 2 clinical experimental models of microangiopathy, in order to provide a pharmacologic rationale for association of diclofenac and heparin. The microcirculation was evaluated by measuring cutaneous blood flow (laser Doppler) and transcutaneous oxygen and carbon dioxide pressures (TcPO(2) and TcPCO(2)) in 10 healthy volunteers before and after producing 2 microcirculatory models of microangiopathy: the models were based on reactive hyperemia (RH) and on local histamine injection, which both produce a significant increase in skin flux and alterations of TcPO(2) and TcPCO(2). The area of the study was the distal medial leg, treated with placebo, DHEP alone (Flector Tissugel), and DHEP/heparin (Flector Tissugel Heparin). The plasters were applied before producing the microcirculatory models to evaluate the efficacy of DHEP and DHEP/heparin in controlling and limiting vasodilatation and development of microangiopathy. A significant increase in cutaneous flux was obtained with both models. The application of DHEP partially limited the increase in flux and in TcPCO(2), as well as the decrease in TcPO(2) (which were considered signs of microangiopathy), but the combination DHEP/heparin was significantly more effective than DHEP alone. The inclusion of heparin in the plaster thus improved the control of the microcirculation achieved with diclofenac alone, when an experimental model of venous/arterial hyperemia and microangiopathy was used. In conclusion, DHEP in association with heparin modulates microcirculatory changes better than DHEP alone. It should be interesting to investigate the product in comparable clinical conditions in which it may be useful to act pharmacologically both on inflammation and microcirculatory disturbances that delay the recovery of patients.

Venoruton vs Daflon: evaluation of effects on quality of life in chronic venous insufficiency.
The aim of this independent study was to investigate differences in efficacy between oxerutins (Venoruton) and 500 mg micronized diosmin + hesperidin (D+H) (Daflon) in patients with chronic venous insufficiency (CVI), evaluating venous-related quality of life (Ve-QOL). A first group of 90 patients with severe venous hypertension (CVI, ankle swelling) was randomized to treatment with oxerutins or D+H. The oxerutins group received oral oxerutins (2 g/day); the D+H group received 3 (500 mg) tablets daily every 8 hours for 8 weeks. A second group of 122 comparable patients was included in a registry following the same study format. The 2 treatments were administered with the same methods and procedures. Clinical conditions were comparable. All patients completing 8 weeks of treatment were included in a registry. Specialists or general practitioners included patients when they considered that clinical conditions were compatible with treatment indications using 1 of the 2 treatments on the basis of their evaluation and experience. When cases were compatible with the registry, the prescribing physician communicated the case to our monitoring center. Patients were evaluated without interfering with their treatment. The main target of evaluation for this study was the change in Ve-QOL (range, 0-100) induced by treatment. A specific Ve-QOL questionnaire was used for this study. Ve-QOL score is a specific expression of the changes in QOL induced by CVI in patients between 35 and 75 years old (defined in our population studies) in which no other significant clinical disease is present (as a confounding factor affecting QOL). Two hundred twelve patients completed the 2 parts of the study. The 2 treatment groups were comparable for age and gender distribution. The mean age was 42 years (SD +/-5.5) in the oxerutins group and 41.5 (SD +/-6) in the D+H group. There were no differences in the severity of CVI between the treatment groups at inclusion. A significant decrease (46.8%, p <0.05) in Ve-QOL score; that is, improvement, was observed in the oxerutins group. The change in Ve-QOL was significantly less in the D+H group (15.5%). In conclusion, CVI, venous microangiopathy, and edema were significantly improved by the treatment with oxerutins; the improvement in QOL was significantly greater in the oxerutins group. The comparison with D+H indicates that oxerutins is comparatively more effective on Ve-QOL and on signs/symptoms of CVI.

Cramps and muscular pain: prevention with pycnogenol in normal subjects, venous patients, athletes, claudicants and in diabetic microangiopathy.
The aim of this study was to assess the preventive action of Pycnogenol (Horphag Research Ltd, UK) on cramps and muscular pain in different groups of subjects and patients. The study included a 5-week observation period (4 weeks treatment and one follow-up week after the suspension of treatment) to evaluate the efficacy of Pycnogenol after its withdrawal. Four 50 mg capsules (total dose 200 mg/day) were prescribed with suggestion to drink at least 1.5 liters of water every day. In the first part of the study 66 healthy subjects completed a 5-week follow-up period. The difference between number of cramps attacks recorded within the 2 weeks before inclusion and the number of episodes during the fourth (p <0.05) and fifth (p <0.05) week were statistically significant. In normal subjects the average number of episodes was reduced from 4.8 (1.2) events per week to 1.3 (1.1) at 4 weeks (p <0.05). In venous patients the decrease in events was from 6.3 (1.1) to 2.6 (0.4) per week (p <0.05). In athletes the number of episodes decreased from 8.6 (2) to 2.4 (0.5) (p <0.05). The decrease was still present at 5 weeks in the 3 groups, to levels significantly lower than inclusion values (p <0.05). In the second part of the study, patients with intermittent claudication and diabetic microangiopathy were evaluated and treated (4 weeks). The groups treated with Pycnogenol and the control, placebo groups were comparable. There was a significant decrease in the number of cramps episodes (p <0.05) and in the score concerning muscular pain (p <0.05) in claudicants and diabetics. No significant effects were observed in the placebo groups. In conclusion, cramps and muscular pain, common in these 2 types of patients, were decreased by the use of Pycnogenol. Globally, these results suggest that the use of Pycnogenol prevents cramps, muscular pain at rest, and pain after/during exercise in normals, in athletes prone to cramps, in patients with venous disease, in claudicants, and in diabetics with microangiopathy. The difference is statistically significant considering objective observations (cramps episodes) and evaluating more subjective aspects (score). This indicates that Pycnogenol is effective in reducing pain and cramps during retraining and rehabilitation increasing its efficiency. In starting any physical rehabilitation program, particularly in vascular subjects, the limitation in mobility associated with muscular pain and with cramps tends to be relevant, and controlling these symptoms is useful to speed up the retraining process.

Improvement of diabetic microangiopathy with pycnogenol: A prospective, controlled study.
The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd, United Kingdom) in patients with diabetic microangiopathy. Patients without a history of diabetic ulcerations were treated with Pycnogenol. Patients received oral Pycnogenol (50 mg capsules, 3 times daily for a total of 150 mg daily for 4 weeks). A group of 30 patients was included (severe microangiopathy); 30 comparable patients were observed as controls (no treatment during the observation period). All patients (age, 59 years; range, 55-68 years; male:female = 18:12) included in the treatment group completed the 4-week study. Also, all controls completed the follow-up period. There were no drop-outs. All included subjects had signs and symptoms of diabetic microangiopathy. The duration of diabetes-from the first signs/symptoms--was on average 7.5 years (SD = 3). After 4 weeks, microcirculatory and clinical evaluations showed a progressive decrease in skin flux at rest in the foot (indicating an improvement in the level of microangiopathy), a significant decrease in capillary filtration, and a significant improvement in the venoarteriolar response in all treated subjects. There were no visible effects in controls except a slight reduction in skin flux at rest in the foot. Treatment was well tolerated in both groups. In conclusion, this study confirms the clinical efficacy of Pycnogenol in patients with diabetic microangiopathy. The study indicates the clinical role of Pycnogenol in the management, treatment, and control of this common clinical problem. The treatment may be also useful to prevent diabetic ulcerations by controlling the level of microangiopathy.

Rapid relief of signs/symptoms in chronic venous microangiopathy with pycnogenol: a prospective, controlled study.
The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd, UK) in patients with severe chronic venous insufficiency. Patients with severe venous hypertension (chronic venous insufficiency, ankle swelling) and history of venous ulcerations were treated with Pycnogenol. Patients received oral Pycnogenol (50 mg capsules, 3 times daily for a total of 150 mg daily) for 8 weeks. A group of 21 patients was included in the treatment group and 18 equivalent patients were observed as controls (no treatment during the observation period). All 21 patients (age 53 years; range, 42-60 years; M:F=11:10) in the treatment group completed the 8-week study. Also the 18 controls completed the follow-up period. There were no drop-outs. The average ambulatory venous pressure was 59.3 (SD 7.2; range 50-68) with a refilling time shorter than 10 seconds (average 7.6; SD 3). There were no differences in ambulatory venous pressure or refilling time between the treatment and control patients. The duration of the disease-from the first signs/symptoms-was on average 5.7 years (SD 2.1). At 4 and 8 weeks, in all Pycnogenol-treated subjects, microcirculatory and clinical evaluations indicated a progressive decrease in skin flux, indicating an improvement in the level of microangiopathy; a significant decrease in capillary filtration; a significant improvement in the symptomatic score; and a reduction in edema. There were no visible effects in controls. In conclusion, this study confirms the fast clinical efficacy of Pycnogenol in patients with chronic venous insufficiency and venous microangiopathy. The study indicates the significant clinical role of Pycnogenol in the management, treatment and control of this common clinical problem. The treatment may be also useful to prevent ulcerations by controlling the level of venous microangiopathy.

Serological and molecular studies of HLA in Sardinian patients with Graves' disease.
HLA Class I and Class II antigens were studied in 103 unrelated Sardinian patients with Graves' disease (GD), 71 of whom had ophthalmopathy, and in 220 healthy controls. Molecular typing of the DQB1 allelic variants was carried out on 34 GD patients and 35 healthy controls, selected for the HLA-DR2-DQw1 phenotype. The results of the serological typing showed a positive association with the DR2 and the DQw1 antigens and a negative association with DR3 and DQw2 antigens. These associations were stronger in the GD patients with ophthalmopathy. The DQB1 molecular analysis in patients with the HLA-DR2-DQw1 phenotype revealed the presence of the DQB1*0502 allele in 91.1 per cent of the patients and in 82.2 per cent of the controls. In the Sardinian population GD seems to present a different HLA association than that observed in other Caucasian populations (DR3-Dw24). The DR2 and DQw1 positive associations may be explained by the high frequency of the DQB1*0502 allelic variant (37.7 per cent) which is rare in the other Caucasian populations. The absence of an association between DR3 and GD in Sardinia can be attributed to the very low frequency of the HLA-B8-DR3 (Dw24) haplotype. In fact, in the Sardinian population, DR3 is associated with the allelic variant Dw25 carried by the HLA-B18-DR3 haplotype.

Unrelated bone marrow transplantation in a Wiskott-Aldrich syndrome patient sharing two HLA-extended haplotypes with the donor.
We report a case of BMT from an unrelated donor (MUD) in a patient affected by Wiskott- Aldrich syndrome (WAS). The donor-recipient pair was completely identical for two HLA-extended haplotypes. The conditioning regimen consisted of Bu 14 mg/kg followed by CY 200 mg/kg. GVHD prophylaxis was carried out with CsA plus short-term MTX. Allogeneic engraftment was obtained without any signs of acute or chronic GVHD. At fifteen months from the transplant the patient was in an excellent clinical condition. This case confirms the role of BMT from MUD in WAS, and suggests that complete donor-recipient identity for two entire HLA-extended haplotypes is a particularly favorable immunogenetical condition in this type of transplant.
