Objective. To investigate whether hypersensitivity is more common in Complex Regional Pain Syndrome type 1 (CRPS1) patients than in the general population. In a recent study, the level of tryptase, a specific marker for mast cells, was significantly higher in blister fluid from the involved extremity of CRPS1 patients. This suggested that mast cells may play a role in the pathophysiology of CRPS1. Mast cells are major effectors in allergic reactions, and are also involved in a variety of noninfectious inflammatory diseases. Patients. Sixty-six Dutch patients with CRPS1 in one extremity were included. Outcome Measures. Allergy information was obtained from the medical history and a modified questionnaire based on the Europees Luchtweg Onderzoek Nederland 1 study. Total IgE and allergen-specific IgE were measured from blood samples. Also tryptase, as a marker for mast cells, was measured. The data from the questionnaire were compared with that of the general Dutch population, and the plasma levels were compared with reference values and data in the literature. Results. The medical history did not differ from information provided in the questionnaire by the CRPS1 group. There was no significant difference between the answers to the questionnaire between the CRPS1 patients and the general population. The total IgE levels were elevated in 30% of the CRPS1 patients compared with 15 - 24% of the general population, and allergen-specific IgE and tryptase levels were comparable with the reference values. Conclusions. Based on the medical history, an allergy questionnaire, and objective laboratory findings we conclude that IgE-mediated hypersensitivity is not more common in CRPS1 patients than in the general population.
