Impact of autoimmune gastritis on chronic urticaria in paediatric patients - pathophysiological point of views.

Unlabelled: We would like to provide an updated comprehensive perspective and identify the components linked to chronic spontaneous urticaria (CSU) without specific triggers in autoimmune atrophic gastritis (AAG). AAG is an organ-specific autoimmune disease that affects the corpus-fundus gastric mucosa. Although we lack a unified explanation of the underlying pathways, when considering all paediatric patients reported in the literature, alterations result in gastric neuroendocrine enterochromaffin-like (ECL) cell proliferation and paracrine release of histamine.

Recombinant human C1 esterase inhibitor treatment for hereditary angioedema attacks in children.

Background: Attacks of hereditary angioedema (HAE) due to C1 esterase inhibitor deficiency (C1-INH-HAE) usually begin during childhood or adolescence. However, limited data are available regarding indications and modalities of treatment of children. This study evaluated recombinant human C1-INH (rhC1-INH) for HAE attacks in children.

The Clinical Relevance of Various Hypersensitivity Tests in Patients with Atopic Dermatitis as Assessed by Their History, SCORAD Changes, and Number of Days with Need of Anti-Inflammatory Treatment.

Immediate and delayed hypersensitivity reactions can play a role in the pathogenesis of atopic dermatitis (AD). We tested 71 patients (median age 5 years) with AD for hypersensitivity to grass and birch pollen, , and using atopy patch test (APT), skin prick test (SPT), and specific IgE measurement. The sensitivity (SE) and specificity (SP) of the tests were calculated on the basis of personal history of AD exacerbation, clinical AD score (SCORAD) changes, and the number of days with need for topical anti-inflammatory treatment (AITD) in relation to exposure to the allergens being tested.

[Detection of Babesia canis (Piroplasmida) DNA in the blood samples and lysates of the ticks Dermacentor reticulatus (Ixodidae) collected in the Tula and Moscow Regions].

Chimeric primers, the sensitivity and specificity of which allow them to be used in both the clinical setting and the epizootological assessment of tick infection by a real-time polymerase chain reaction (RT-PCR) assay, have been designed against Babesia canis infection. The findings suggest that a large number of Babesia DNA copies are detectable in the blood in acute babesiosis. Some animals that had experienced babesiosis developed blood B.
