Abstract
- Background: Dermatitis herpetiformis (DH) is a subepidermal bullous disease characterized by a neutrophilic and eosinophilic infiltrate, together with activated lymphocytes that show preferential polarization towards the Th2-like phenotype. To date, the role of neither soluble mediators, such as cytokines, nor serum levels of myeloperoxidase (MPO), eosinophil cationic protein (ECP) and tryptase (TRY) have been studied in the peripheral blood of DH. In this study we investigated 40 DH subjects for possible alterations in MPO, ECP, TRY, eotaxin, interleukin (IL) 4 and IL-5 concentrations to evaluate the role of neutrophils, eosinophils and mast cells in the induction of skin lesions. Sera from 20 healthy subjects were tested as controls.<br />Methods: Eotaxin, IL-4 and IL-5 serum contents were determined by a solid-phase enzyme-linked immunosorbent assay. A double antibody radioimmunoassay was used to measure serum levels of MPO, ECP and TRY.<br />Results: Normal levels of eotaxin and IL-4 were found in all DH subjects; increased IL-5 levels were found only in 1 subject. The MPO levels were significantly higher in DH subjects than in healthy controls (p < 0.01). There was also a significant difference between the serum ECP levels of DH and healthy controls (p < 0.05). TRY was not revealed in the serum of DH subjects.<br />Conclusions: The determination of Th2-like cytokines and TRY serum levels is not important in quantifying the involvement of activated lymphocytes and mast cells in DH; however, the finding of high MPO and ECP serum levels seems to confirm that these products are good markers of the presence of activated neutrophils and eosinophils.<br /> (Copyright 2002 S.
