Tryptase and myeloperoxidase respectively represent 2 specific markers of activated mast cells or neutrophils. Therefore, establishing the levels of these enzymes may be useful to quantify the cell involvement in the tissues or fluids of different origins and in different pathologies. The aim of this study was to analyse the levels of these 2 markers in both the sera and blister fluids of patients affected with bullous pemphigoid. These levels were then correlated to the concentrations of 19 cytokines and 2 soluble adhesion molecules determined in the same samples and also with the log (anti-basement membrane zone antibody) titres, evaluated in the patients' sera. For these purposes, 15 patients with bullous pemphigoid (10 males and 5 females; median age: 84 years, range 66-87; median disease duration: 0 years, range 0-3: median number of skin lesions: 17, range 14-30; median anti-basement membrane zone antibody titre: 1:320, range 0.0-1:2560) and 15 normal subjects (11 males and 4 females, median age: 81 years, range 59-86) were analysed by means of commercially available kits. Results showed that blister fluid myeloperoxidase and tryptase levels were increased as compared with the respective sera (P |
