ABSTRACT BACKGROUND: The primary role of infections in chronic urticaria (CU) is controversial. We hypothesised that streptococcal tonsillitis (ST) could be a primary cause of CU or acute recurrent urticaria (ARU). METHODS: Retrospective study of 14 outpatients observed between January 2000 and December 2009, with CU/ARU and clinical and/or laboratorial suspicion of an aetiopathogenic link with ST. Clinical history, objective examination and laboratorial study were looked for. Three groups were defined: spontaneous resolution of urticaria, resolution after tonsillectomy, and still symptomatic. RESULTS: In these patients, a causal relationship between ST and urticaria is supported by: markers of streptococcal infection, the perception of a clinical relationship between tonsillitis and urticaria, the decrease of urticaria severity with early antibiotherapy to tonsillitis and urticaria resolution after tonsillectomy. CONCLUSIONS: Our study encourages the investigation of tonsillitis in these otherwise idiopathic patients, especially until young adulthood and even in the absence of any symptoms.

  • Article: First attack of acute urticaria in pediatric emergency department.
    [show abstract] [hide abstract]
    ABSTRACT: Management of a first attack of acute urticaria in children is dependent on the etiology of the disease. Knowledge of the various etiologies of urticaria will help primary physicians to perform appropriate clinical assessments. In this study, we analyzed the etiologies and their prevalence in first-attack acute urticaria in infants, children and adolescents in central Taiwan. This was a retrospective study of 953 children who were admitted to the emergency department (ED) with a first attack of acute urticaria from January 2000 to December 2006. All patients were followed in the ED or outpatient department until their symptoms subsided. Patient demographics and detailed etiologies of the first attack of acute urticaria were analyzed. Furthermore, the prevalence of various etiologies in different age groups, as well as the etiologic trends of acute urticaria in children during the previous 7 years, was determined. The most common etiologies of a first attack of acute urticaria in children were various infections (48.4%), foods (23.5%), idiopathic causes (13.2%), and medications (11.5%). Among the three major etiologies above, upper respiratory tract infections (nasopharyngitis), seafood (shrimp) and nonsteroidal anti-inflammatory drugs (ibuprofen) were the most frequent causes. Moreover, the etiologies differed significantly with patient age (p < 0.001). Overall, infections were the major cause in infants (56.5%), whereas food (36.6%) and medications (26.8%) were the most common etiologies in adolescents. The prevalence of various infections dropped as the age of the children increased (56.5% in infants, 51.2% in preschool-aged children, 42.1% in school-aged children and 17.1% in adolescents). The etiologies of foods and medications were more prevalent in adolescents than in younger children. Detailed etiologies of first-attack urticaria in children in central Taiwan were analyzed. Most importantly, we found that there was a decrease in the prevalence of various infections as causative factors as the age of the children increased. The etiologies of foods and medications were more prevalent in adolescents than in younger children.

  • Article: Chronic urticaria and infections.
    [show abstract] [hide abstract]
    ABSTRACT: The pathogenesis of chronic urticaria is multifactorial and a specific treatment is lacking. In acute urticaria there is no doubt of a causal relationship with infections and all chronic urticaria must start as the acute form. However, in the chronic form a primary role for infection is controversial, although it is undeniable that concurrent infections exacerbate the condition. This is the first English language review based on a detailed analysis of current peer-reviewed publications dealing with infections and chronic urticaria. In chronic urticaria there is a lot of evidence for different infections, but randomized controlled trials are missing. The prevalence of infections is not increased but in susceptible patients the immune response may lead to the development of chronic urticaria. Interestingly, there is evidence for an infection-associated autoreactive response at least in the subgroup with a positive autologous serum skin test. A variety of mechanisms have been invoked to explain these observations, including molecular mimicry. Actually the arguments for an important role of underlying causal infections in chronic urticaria are weak, from an evidence-based viewpoint, but there are data suggesting a link. Moreover, an association with underlying or precipitating infectious causes is difficult to establish because there is no possibility for challenge and the number of other urticarial triggers is vast. For the future it will be necessary to reveal the link between urticaria, autoreactivity, non-immunoglobulin E-mediated hypersensitivity reactions and infections to find attractive and specific therapeutic interventions for urticarial symptomatology.

  • Article: Helicobacter pylori infection in patients with chronic urticaria: correlation with pathologic findings in gastric biopsies.
    [show abstract] [hide abstract]
    ABSTRACT: Chronic urticaria is a persistent urticaria lasting longer than 6 weeks, affecting 20% of the general population. Various infectious agents have been reported as causes of urticaria, including Helicobacter pylori, which is a common worldwide bacterial infection. Its role in inducing allergic conditions, such as chronic urticaria, has been suggested in some reports and ignored in others. To assess the prevalence of H. pylori infection in patients with chronic urticaria and to explore the possible etiopathogenetic link between them. Thirty-five patients suffering from chronic urticaria and 10 normal control individuals were subjected to upper endoscopic gastric biopsies to assess and semiquantify H. pylori infection and to address other pathologic abnormalities, using routine hematoxylin and eosin staining and Giemsa staining. Forty percent of control subjects and 57% of patients were positive for H. pylori infection, but the difference did not reach statistically significant levels (P = 0.47). The severity of urticarial symptoms was greater in the H. pylori-positive than in the H. pylori-negative group (P = 0.019). Heavy bacterial colonization (P = 0.008) and intense gastric inflammation (P < 0.0001) were associated significantly with severe clinical manifestations. Eighty percent of the H. pylori-positive urticaria group experienced complete remission after receiving eradication therapy for H. pylori. Helicobacter pylori may have a role in the exacerbation of urticarial symptoms, even though it is not involved directly in its etiology, and its eradication may lead to symptom improvement in a considerable number of infected urticaria patients. The severity of symptoms is dependent on the density of bacterial infection and the intensity of inflammatory infiltrate in the gastric biopsy.
