The purpose of this study was to evaluate frequency of contact allergy in patients with chronic venous leg ulcers (CVLU) and to estimate possible relationships between allergic contact reactions and characteristics of both chronic venous insufficiency (CVI) and CVLU. We performed patch tests with the European standard series, antibiotics, glucocorticosteroids and ointment vehicles in 50 patients with CVLU. Patients underwent detailed CVI diagnostics using colour flow duplex ultrasound examination, ankle brachial pressure index determination and leg ulcers area measurement. Positive patch tests results were found in 80% and polyvalent allergy in 56% of patients. Statistically significant correlations were recorded between CVI and CVLU duration, CVLU duration and CVLU area and between CVI duration and polyvalent allergy frequency. Statistically significant differences were observed between coexistence of superficial and deep system insufficiency and CVLU duration, characteristics of contact allergic reactions and CVI duration, frequency of allergic contact reaction and presence or absence of long saphenous vein insufficiency, incidences of vein thrombosis and characteristics of contact allergic reactions as well as between characteristics of contact allergic reactions and both CVLU duration and area. Complex pathophysiological processes, including inflammatory reactions, in course of CVI may influence development of allergic contact reaction in CVLU patients.
