The treatment outcomes and dose de-escalation of desloratadine up-dosing in chronic spontaneous urticaria

Abstract

Background

An increase in dosages up to fourfold of second generation antihistamines is recommended for recalcitrant chronic spontaneous urticaria (CSU). No regimen guidelines about dose de-escalation, however, are mentioned once the disease is controlled.

Objective

To demonstrate the treatment outcomes and dose reduction in desloratadine assessed using the urticarial activity score over 7 consecutive days.

Methods

Medical records of all patients with CSU treated with desloratadine were collected retrospectively during a period from January 2010 to December 2013.

Results

Sixty-seven (94.4%) patients had remission of the disease with variable doses of desloratadine. The patients who had CSU concomitant with antithyroid antibodies or high erythrocyte sedimentation rates had a greater tendency not to respond to the standard dose. Once the disease was completely controlled, 67 patients finished the treatment, but 63 (94%) patients had recurrent symptoms. Sixty-three patients took the same dose that induced the response for a further 4 weeks before stopping or reducing the dose, 41/63 (65.1%), however developed urticaria again. Forty-one patients took the same dose for a further 8 weeks; only 2/41 (4.9%) patients developed the rash again. The mean follow-up period after the disease was controlled was 7.5 months.

Conclusion

Most patients need higher than the standard doses to obtain remission. Once the disease is completely controlled, however, maintenance of the same dosage for at least 8 weeks before dose reduction is suggested in order to avoid recurrence of the symptoms.
