Abstract
Purpose of Review: Chronic urticaria is a common and often frustrating condition that physicians encounter in the outpatient setting. Its management continues to be a challenge, and an exogenous cause for chronic urticaria is only found rarely. Helicobacter pylori has been implicated as a factor for many disorders and proposed as an etiologic factor for chronic urticaria. We aim to provide a comprehensive review of the data on H. pylori eradication for treatment of chronic urticaria by utilizing the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to analyze and determine the quality of evidence for this proposed therapy. Recent findings: Although H. pylori eradication has been recommended as part of routine chronic urticaria management by multiple authors, the trials of H. pylori eradication in the treatment of chronic urticaria have yielded conflicting results and suffer from substantial methodological limitations. Summary: Our critical appraisal of the 10 trials showing the benefit of H. pylori eradication in patients with chronic urticaria leads to an overall very low grade for this intervention. Appraisal of nine studies in which H. pylori eradication showed no benefit in the course of chronic urticaria also leads to an overall very low grade. The evidence that H. pylori eradication leads to improvement of chronic urticaria outcomes is weak and conflicting; this leads to a weak recommendation for routine H. pylori eradication for patients with chronic urticaria. For this reason, a decision to proceed with this management should be considered carefully in the context of relative harms/burdens and benefits, as well as patient values and preferences.
