Since 1983 when patients with type B gastritis were found to be infected by a hitherto unknown type of bacteria showing a certain similarity to Campylobacter, the prognosis of this disease has changed considerably with the availability of highly effective antibiotics. The Gram-negative bacterium was identified as Helicobacter pylori, which causes most cases of gastritis and of peptic and duoden...

In the last few decades, increasing understanding of the pathomechanisms involved in chronic urticaria has highlighted the heterogeneity of different subtypes, and chronic urticaria is now classified as chronic spontaneous urticaria and inducible urticaria. Although many factors are thought to be involved in chronic urticaria, the etiology is yet to be clarified. The purpose of this study was t...

OBJECTIVE To describe a case of chronic urticaria in a female adolescent associated with Helicobacter pylori infection, confirmed in two different occasions, with improvement of urticaria after the antibacterial treatment. CASE DESCRIPTION A 13-year-old female patient sought medical care with chronic urticaria and epigastric pain unresponsive to medical treatment. Laboratorial tests for furth...

Chronic urticaria (CU) in children often is caused by physical triggers. It also can be associated with autoimmune disease, especially thyroid autoimmunity. Functional autoantibodies against FcepsilonRIalpha have been reported in children with CU but have not been studied in a systematic fashion. The autologous serum skin test has been proposed as a surrogate test to define the presence of thes...

Results Serology for hepatitis B was found to be positive in 8 patients (3.38%) in the acute spontaneous urticaria group, in 9 patients (5.35%) in the chronic spontaneous urticaria group and in 5 subjects (2.27%) in the control group. Antibodies to HCV were identified in 3 patients (1.27%) with acute spontaneous urticaria, in 4 patients with chronic spontaneous urticaria (2.38%) and in one subj...

Urticaria is a group of diseases that share a distinct skin reaction pattern. Triggering of urticaria by infections has been discussed for many years but the exact role and pathogenesis of mast cell activation by infectious processes is unclear. In spontaneous acute urticaria there is no doubt for a causal relationship to infections and all chronic urticaria must have started as acute. Whereas ...
