s-5682 and Edema

The author characterizes the edema as an important quantitative objective measure of severity for chronic venous diseases in both early and advanced stages. The problems of edema assessment methods and the importance of its management in clinical practice are discussed. The results of studies on the use of micronized purified flavonoid fraction (MPFF, Detralex) for edema syndrome coping are presented.

Inflammation activates leukocytes causing the release of agents that disrupt the endothelial barrier to such an extent that retention of plasma protein is impaired. This phenomenon can be observed using microvascular methods in which ischemia-reperfusion-induced inflammation-like condition are analyzed in terms of the increased adherence of leukocytes to the venular endothelium. Pretreatment with Daflon 500 mg, a purified, micronized, flavonoid fraction consisting of 90% diosmin and 10% hesperidin, prior to the induction of 4 h of tourniquet ischemia significantly lowers the number of adherent leukocytes. This observation is linked to the protective effect of flavonoids in the treatment of edema, as decreased activation is also associated with a decreased platelet and complement system activation, leading to a lowered release of histamine and decreased leukocyte-dependent endothelial damage. It is proposed that attenuation of leukocyte adherence during ischemia-reperfusion is evidence of the protective endothelial effect of Daflon 500 mg and its ability to control edema in clinical situation.

Sclerotherapy is a common technique for the removal of intradermal veins. This study examined the rationale for prescribing micronized purified flavonoid fraction (MPFF) in clinical, etiological, anatomic, pathophysiologic (CEAP) class C1 patients with dilated intradermal veins scheduled for sclerotherapy.. In a national, multicenter, observational program, physicians recruited CEAP C1s patients scheduled for sclerotherapy. The decision to prescribe adjuvant MPFF (1000 mg/day for 6 weeks beginning 2 weeks before sclerotherapy) was made according to usual practice. Disease severity and treatment outcomes were assessed at baseline and 4 weeks post-sclerotherapy using a visual analog scale (VAS) as well as quality-of-life (CIVIQ-14) and patient satisfaction (Darvall) questionnaires.. A total of 70 physicians recruited 1150 patients: 1071 (93%) women, 79 (7%) men. Mean age (± SD) was 40.7 ± 10.7 years (range 18-74) and mean body mass index was 23.6 ± 3.3 kg/m. Resolution of venous symptoms post-sclerotherapy was greater in patients treated with MPFF compared with those undergoing sclerotherapy alone, supporting the rationale for use of MPFF in patients undergoing sclerotherapy..

In both adjuvant arthritis and rheumatoid arthritis, edema and inflammation appear in synovial joints. Edema or effusion reflects an imbalance in lymph dynamics. Purified micronized flavonoid fraction is mainly used in the treatment of chronic venous insufficiency. This compound improves lymphatic drainage with a signicant increase in lymphatic flow and lymphatic pulsality. It is suggested that the beneficial effect of purified micronized flavonoid fraction may be involved in the treatment of adjuvant arthritis in rats.. To evaluate the effect of Detralex on methotrexate prophylactic treatment of adjuvant arthritis in rats.. Groups of rats with adjuvant arthritis were treated with methotrexate (0.6 mg/kg/week), Detralex (20 mg/kg/day) and their combination for 50 days from adjuvant application. Hind paw swelling, arthrogram scores, serum albumin level, serum nitrite/nitrate concentrations and whole body mineral density were evaluated as markers of inflammation and destructive changes associated with arthritis.. Long-term prophylactic treatment with low dose methotrexate significantly inhibited the markers of both inflammation and arthritis. Detralex administered alone slightly decreased both the hind paw swelling and the arthritic score. Other inflammatory and arthritic markers were not significantly influenced. However, Detralex combined with methotrexate markedly potentiated the beneficial effects of methotrexate, which resulted in a more significant reduction in hind paw swelling, arthritic scores, and serum concentrations of nitrite/nitrate. Interestingly, the arthritis-induced decrease of BMD in AA rats was significantly lower only in the group treated with the combination of Detralex+methotrexate.. Detralex increased the therapeutic efficacy of methotrexate basal treatment in AA. We suggest that this may be related to the beneficial effect of Detralex on microcirculation, especially on venules and lymphatic vessels.

Some pharmacologic activities of a micronized flavonoid complex consisting of 90% diosmin + 10% hesperidin (Daflon 500 mg*) have been investigated by use of various experimental models: (1) interference with mechanisms of edema (synthesis of arachidonic acid derivatives, microvascular hyperpermeability induced by bradykinin, ischemia, or streptozotocin), (2) interference with lymphatic drainage (thoracic duct fistula in the dog).. Daflon 500 mg inhibited prostaglandin E2 (PGE2) and thromboxane A2 (TxA2) synthesis during a one-month oral daily treatment (100 mg.kg-1.day-1) in the rat, after induction of chronic inflammation by subcutaneous implantation of sponge fragments. Microvascular hyperpermeability induced by bradykinin or ischemia in the rat cremaster muscle was reduced after an oral treatment with Daflon 500 mg (100 mg.kg-1 twice daily). Microvascular hyperpermeability of the streptozotocin-induced diabetic rat was antagonized when Daflon 500 mg (300 mg.kg-1 once daily) was given orally as a preventive treatment. In the anesthetized dog, an increase in lymphatic flow, correlated with administered doses, was observed after IV injection of Daflon 500 mg. Lymphatic flow was maximal twenty minutes after injection of the drug (12.5 mg.kg-1) and was three times higher than the basal flow.. The protective effect of Daflon 500 mg against the formation of perivascular edema and its therapeutic value in the treatment of venous stasis could be explained by its inhibitory activity on the inflammatory process or ischemia-induced hyperpermeability and by its stimulatory effect on the pulsatile activity of lymphatic vessels.
