Latex hypersensitivity manifests itself most commonly with contact urticaria. In this study, we investigated the frequency of latex hypersensitivity as a possible aetiological factor in patients with chronic urticaria (CU) and compared latex hypersensitivity of CU patients (n = 50) with that of rubber factory workers (n = 50) and healthy controls (n = 50). Prick test with latex and fruit extracts and determination of latex-specific immunoglobulin E (IgE) were performed. As a risk factor, contact dermatitis due to rubber additives was tested by patch test. Latex hypersensitivity was detected in 14% of CU patients, 12% of rubber factory workers and 12% of healthy controls (P > 0.05). Positive patch test with rubber additives was detected in 6% of CU and 4% of rubber factory workers. 3 of 7 CU patients had sensitivity to fruits in addition to latex hypersensitivity. In 1 patient with CU, the clinical complaints were found to be related to latex hypersensitivity. These findings suggest that the frequency of latex hypersensitivity in CU patients is no higher than that in healthy individuals. However, CU patients should be carefully asked about latex allergy, as we demonstrated that 1 of the CU patients had undiagnosed symptomatic latex allergy.
