This study is for those people with difficult to treat hives. We are investigating whether or not a different medication, hydroxychloroquine, works to treat a certain type of hives. Hydrochloroquine is currently approved by the Food and Drug Administration (FDA), for treating arthritis, therefore it is considered investigational in this study.
Hypothesis: Hydroxychloroquine will prove to have an efficacious response in terms of Urticarial Symptoms, on patients with chronic urticaria.
Our research question is: Is hydroxychloroquine an efficacious medicine to use in patients with chronic urticaria? Answering this question should help allergists treat chronic urticaria with a more evidence based approach. To date there has one been one prospective trial evaluating hydroxychloroquine in hives, and although it showed a trend towards efficacy (0.05
We plan to ascertain the efficacy of hydroxychloroquine by completing a randomized double blinded placebo controlled study of treatment in patients with chronic urticaria. We will be measuring an Urticarial Score to evaluate hive symptoms. We will be measuring them at baseline, and at the end of the study to note change in drug vs placebo.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment
