Background: Chronic urticaria patients who demonstrate autoantibodies against the high-
affinity receptor of IgE (FceRI) or IgE itself tend to have a high itch and wheal score, and
systemic symptoms may have a significant bearing on their management in terms of super
pharmacologic doses of antihistamines needed or use of immunomodulators. Most studies
have used histamine release assays rather than autologous serum skin tests (ASSTs) for
correlating urticaria severity and histamine releasing activity. Methods: An ASST was …

Abstract Background: The Helicobacter pylori infection is linked to chronic urticaria in nearly
60% of patients. We studied clinicoepidemiologic features in patients with chronic urticaria
with and without H. pylori infection. Methods: Endoscopic antral biopsy for the rapid urease
test (RUT) and histopathology, and serum IgG ELISA for H. pylori infection were performed
in 150 patients (male: female ratio 1: 2.4) of chronic urticaria aged 18-68 years.
Clinicoepidemiologic features including age, gender, age of onset and duration, frequency …
