Whatís New in Hives (urticaria)

Hives causes a high degree of itching where patients frequently cannot obtain a decent nightís sleep. It is relatively common in both children and adults. Treatment is complicated since identifying the trigger is often difficult and patients frequently cannot tolerate the stronger prescriptions available due sleepiness (sedation). The largest improvement is obtained with systemic steroids (either administered as an injection or as pills), but this is not a good long term solution. Thus, patients often ask how long they will be afflicted with the condition. Before, I didnít have good data with which to answer this question but recently a study was performed which provided an answer at least for children. A study of 92 children found that hives resolved after a median duration of 4.3 years. Of course, some resolved sooner (18.5% at 1 year) and some resolved later (67.7% at 5 years). Unfortunately, most of the parents of my patients come in hoping the hives will resolve after a few days and are not excited to hear the average of ~4 years.

While I hope one day for a cure for hives (or at least a highly effective treatment with few/no side effects), at least this gives some of my patients (and parents of those patients) some answers. If you or your child suffers from hives, or have other questions, I look forward to seeing you. Please make an appointment for a dermatology consultation at (626) 331-6411.
