ABSTRACT
Objective@#The aim of this study is to investigate the effect of sublingual immunotherapy with Dermatophagoides Farinae on the expression of specific IgG4(sIgG4) in patients with allergic rhinitis (AR) in Hainan area.@*Method@#Seventy-two patients with dust-mite allergic rhinitis, all three generations of whom were local islanders in Hainan, were randomly divided into control group(36 cases) and SLIT group(36 cases). sIgG4 and sIgE expression levels were detected before treatment, 6 months after treatment, 12 months after treatment, and 18 months after treatment. The patient's symptom score, medication score, VAS score and adverse reactions was also assessed. Finally, through statistical analysis of the relevant data collected at 4 time points in the two groups of patients, the efficacy, safety and changes of sIgG4 antibody expression level in patients with allergic rhinitis receiving sublingual specific immunotherapy in Hainan were observed. @*Result@#Symptoms scores, medication scores and VAS scores were significantly improved in the SLIT group after treatment compared with before treatment(P<0.05), and serum sIgG4 increased significantly(P<0.01), serum sIgE showed no significant change(P>0.05). In the control group, symptom scores, medication scores and VAS scores were also significantly improved compared with before treatment(P<0.05), while serum sIgG4 and sIgE showed no significant change(P>0.05). When comparing the two groups, Symptoms scores, medication scores and VAS scores of the SLIT group were significantly lower than those of the control group at 12 months and 18 months after treatment(P<0.05). sIgG4 expression levels in the SLIT group were significantly higher than those in the control group after 6, 12 and 18 months of treatment(P<0.01). There was no significant difference in sIgE expression level between the two groups(P>0.05). No severe systemic adverse reactions occurred in the two groups, and 3 patients showed mild adverse reactions in the SLIT group. @*Conclusion@#Sublingual immunotherapy of Dermatophagoides Farinae was effective and could increase the expression of sIgG4 in patients with Dermatophagoides farinae AR, sIgG4 is expected to be an immunological marker for the objective evaluation of the clinical efficacy of Hapten.
