  • Title: [TREATMENT OF REFRACTORY RHINOSINUSITIS IN PATIENTS WITH IGE-DEFICIENCY].
    Author: Tsaryk VV.
    Journal: Lik Sprava; 2014 Dec; (12):3-10. PubMed ID: 26638461.
    Abstract:
    The most significant:clinical manifestation of isolated IgE-deficiency is chronic and recurrent sinopulmonary diseases. A few papers about treatment of IgE-deficiency, which shows the effect of intravenous immunoglobulin (IVIG) at a dose of 300-400 mg/kg was found. The results of such studies has level of evidence D. In our study we included IgE-deficient patients with refractory rhinosinusitis, which confirmed the diagnosis on the basis of at least two-fold examination with an interval of 1 month in the absence of obvious causes of secondary immunosuppression. In the study group included 82 patients (49 female, 34 male) aged 18 to 61, with the refractory rhinosinusitis combined with deficient IgE, total--33 (group 1) and partial--4 patients (group 2). In 22 patients (26.8%) immunoglobulin E deficiency combined with decreased serum concentrations of IgG sub-classes and other classes. The control group are 33 patients with refractory rhinosinusitis who refused IVIG. Immunoglobulinl intramuscularly administered at a dose of 0.3-0.4 ml/kg body weight for 3 days in a row 2-3 courses at intervals of 2-3 weeks. In the absence of clinical effect of said treatment for 2-3 months, we used IVIG at a dose of 200-400 mg/kg 1 month 1-3 courses with the consent of the patient. The clinical ohserved in 49 patients (87%), which was to reduce the number, severity and duration of exacerhations course rhinosinusitis. After IVIG were marked with significantly higher serum concentrations of total IgE in patients with total and partial deficiency compared with the results of intramuscular immunoglobulin. During treatment significantly increased serum concentration not only IgE (from 3.05 IU/ml ± 1.21 IU/ml to 12.5/IU/ml ± 1.86 IU/ml in total deficit; P < 0.01; 7.23 IU/ml ± 1.37 IU/ml to 15.66 IU/ml ± 1.66 IU/ml at partial dcficiency), but significantly increased serum concentrations of total IgG and subclasses IgG1, IgG2. So we found clinical and immunological effect of the intramuscularly and ivig in patients with refractory rhinosinusitis deficient IgE. This clinical and immunological effects we regarded as the influence of small doses of immunoglobulin to Fc-receptors on B lymphocytes mediated by regulatory mechanism of antibody production (Bayry J. et al).
