Effects of sublingual immunotherapy for Dermatophagoides farinae on Th17 cells and CD4(+) CD25(+) regulatory T cells in peripheral blood of children with allergic asthma.

Background: Sublingual immunotherapy is becoming a more common treatment for allergic diseases, particularly in pediatric clinics. This type of treatment is highly effective for Dermatophagoides farinae allergy, but the mechanisms resulting in immune tolerance have not been investigated. We explored the effects of sublingual immunotherapy with D.

[Long-term efficacy of sublingual immunotherapy with Dermatophagoides Farianae Drops in children with allergic asthma sensitized to dust mites].

Objective: To observe the efficacy of sublingual immunotherapy (SLIT) in children with allergic asthma during the treatment and 1 year after the treatment.

Method: This is an open and retrospective study; 80 children with mild-moderate allergic asthma between 4 and 14 years of age were chosen from the Department of Respiratory Medicine, Nanjing Children's Hospital Affiliated to Nanjing Medical University from May to August, 2009. All children were sensitized to Dermatophagoides Farianae and/or Dermatophagoides Pteronyssinus and have received anti-asthma drug therapy for 3 months (baseline).

Correlation between serum H2S and pulmonary function in children with bronchial asthma.

Endogenous hydrogen sulfide (H2S) has generated recent research interest because of its potential function as an inflammatory mediator. Despite its apparent functions in vascular smooth muscle, an important player in airway remodeling in asthma, little research has been done to assess the role of H2S in the pathogenesis of asthma. To determine whether serum H2S concentration is correlated with pulmonary function in children with asthma, we measured serum H2S concentration and pulmonary function indices (FVC, FEV1, PEF, FEF25-75, MEF50 and MEF25) in 64 children with asthma and 60 healthy children.
