Serum concentrations of the derivatives of reactive oxygen metabolites (d-ROMs) in dogs with leishmaniosis.
Leishmania infantum interferes with the oxidative metabolism of phagocytes. In order to assess whether derivatives of reactive oxygen metabolites (d-ROMs) decrease due to infection or increase due to inflammation, d-ROMs were measured in serum collected from control dogs (Group 1; n = 12), from dogs seropositive for Leishmania either symptomatic (Group 2; n = 27) or not (Group 3; n = 14), and from dogs with other diseases (Group 4; n = 16). The concentrations of d-ROMs in the four groups, expressed in Carratelli Units (U CARR) were, respectively, 75.4 ± 39.5 (median, 81.6), 108.2 ± 96.3 (73.4), 73.5 ± 62.2 (62.0), 127.7 ± 97.3 (94.3). There were no significant differences between groups, but dogs with values higher than the reference interval were found, mostly in Groups 2 and 4 (which had serum C-reactive protein levels consistent with inflammation), whilst low values were occasionally found in Groups 2 and 3. Inflammation may mask decreases in d-ROMs induced by Leishmania infection.
