[Clinical profile of patients with chronic urticaria in a tertiary care hospital of the social security system in Costa Ricas].

Abstract

Objective: To describe the medical and laboratory profile of the patients who have been diagnosed with chronic urticaria in the outpatient clinic of a tertiary care hospital of the social security system in Costa Rica.

Methods: All patients over 13 years of age who had been diagnosed with chronic urticaria between January 1st, 2014, and December 31st, 2018 were included. Variables of medical and laboratory data were statistically analyzed, and the treatment of the patients between their first and last medical consultation was compared.

Results: This was about 160 patients who had been diagnosed with chronic urticaria; 129 of them were women, 45.7 % between the ages of 30-49 years; in 17.5 % of them (28 patients), inducible urticaria was associated; 54.8 % (46/84) had positive antithyroperoxidase antibodies; 16.9 % (27 patients) maintained a single dose of second-generation anti-H1 antihistamines in the last consultation; 16.3 % (26 patients) no longer required antihistamine treatment in the last consultation. Cyclosporine was used in 8.8 % (14 patients), and omalizumab was used in 2.5 % (four patients).

Conclusion: Since this is a real-life study in a geographic region with limited publications on this pathology, we trust that the provided information will contribute to the scientific community in order to improve the quality of life of patients with chronic urticaria through a timely diagnosis and an effective and efficient treatment.
