  • Dust Mite Sublingual Immunotherapy for Allergic Rhinitis: A Meta-Analysis

    Objective To assess the effectiveness of dust mite sublingual immunotherapy (SLIT) for treating allergic rhinitis. Methods The randomized controlled trials (RCTs) about SLIT treating allergic rhinitis were collected in MEDLINE, EMbase, The Cochrane library (Issue 10, 2012), CNKI, VIP, WanFang Data and CBM from inception to October, 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was performed by using RevMan 5.1 software. Results A total of 8 RCTs involving 788 patients were included. The results of meta-analysis showed that, compared with the control group, SLIT showed no obvious difference in the total effective rate (RR=1.15, 95%CI 0.88 to 1.50, P=0.29), but it was superior in decreasing the scores of both nasal symptom (SMD= −1.13, 95%CI −2.07 to −0.20, P=0.02) and drug intake (SMD= −0.60, 95%CI −1.06 to −0.15, P=0.009). Conclusion SLIT can improve the symptoms of patients with allergic rhinitis, and it can also decrease the using frequency of antihistamine, beta-blocker and nasal spray steroids.

  • Efficacy of Specific Immunotherapy Combined with Budesonide Formoterol Dry Powder Inhaler for Treatment of Moderate to Severe Asthma

    Objective To evaluate the efficacy of specific immunotherapy in combination with budesonide formoterol dry powder inhaler ( BUD/FM) in the treatment of moderate to severe bronchial asthma. Methods The data of 93 patients with moderate to severe asthma from September 2006 to September 2008 were analyzed. 46 cases who received BUD/FM therapy were recorded as a BUD/FM treatment group, and 47 cases who received BUD/FMand dustmite specific immunotherapy were recorded asa combination treatment group. After 6, 12, 18, and 24 months, asthma symptom scores, pulmonary function,effective rate, and scores of Asthma Quality of Life Questionnaire ( AQLQ) were compared in the two treatment groups. Results Compared with the BUD/FMtreatment group, the effective rate was significantlyhigher ( 83. 0% vs. 65. 2% , P lt;0. 05) , the lung function improvements in FEV1% pred and expiratory peak flow were more significant in the latter period of treatment, and AQLQ scores improved more significantly after 24 months’treatment in the combination treatment group. Conclusion For patients with moderate tosevere asthma, specific immunotherapy in combination with BUD/FMcan improve asthma symptoms and lung function with good compliance and long lasting efficacy.

  • Effects of Lactic Acid Bacteria on Dust Mite Induced Allergic Inflammation in Mice Involving the Regulation of MAPK Signaling

    Objective To investigate the effects and mechanisms of lactic acid bacteria on MAPK signaling in immune response of dust mite sensitized mice. Methods Forty C57BL/6 mice in Group M, P and L, were sensitized and challenged with mite extract while then the animals in Group N were treated with saline as control. The mice in Group L and P were fed with Lactococcus lactis or Lactobacillus respectively.Three days after the last challenge, all mice were sacrificed for lung pathological examination. IL-10 level in culture supernatant of splenocytes stimulated with mite extract was detected by ELISA. The expression of IL-4/ IFN-γon CD3 +CD4 + cells was detected by flow cytometry. Western blot were performed for detection of MAPK signaling ( P38, ERK, and JNK) from mice’s spleen cells stimulated with mite extract. Results The mice fed with Lactococcus lactis ( Group L) had lower rate of eosinophilic airway inflammation and higher level of IL-10 in the culture supernatant of splenocytes than Group P. Meanwhile, the number of CD4 + T cell with IL-4 expression was decreased revealed by the analysis of flow cytometry. P38 signaling inspleen cells was activated in the mice of Group M, similarly in the mice of Group P, but not of Group L.Conclusion Oral treatment of Lactococcus lactis can induce an immune tolerance in response to mite by up-regulating the level of Tr cells secreting IL-10, thus inhibiting activation of P38 signaling.
