RESUMO
Chronic sinusitis is frequently associated with allergy and asthma. Previous studies have shown that serum immunoglobulin E (IgE) levels correlate with allergy and asthma in adults. Because the role of allergic inflammation in the severity of chronic sinusitis remains controversial in children, we set out to determine whether a correlation exists between serum levels of total and specific IgE and the severity of chronic sinusitis in children. Forty-four children with chronic sinusitis were enrolled in the study. Computed tomographic scans were reviewed and scored for the severity of sinusitis. All children were mite-sensitive. Serum samples were assayed for total IgE and specific IgE antibodies to mite allergen using a fluoroimmunoassay. Fourteen subjects had extensive sinus disease. There was no significant difference in the average of total and specific IgE between the subjects with extensive and limited disease (p = 0.562 and 0.755, respectively). Thirty-four subjects were diagnosed with asthma. The subjects with extensive sinus disease had a higher prevalence of moderate to severe asthma than the subjects with limited disease (p = 0.006), but there was no significant difference in the average of total and specific IgE between the subjects with different severities of asthma. (p = 0.833 and 0.425, respectively). The data suggests that levels of total or specific IgE do not correlate with severity of chronic sinusitis in children. Nonetheless, the severity of chronic sinusitis and asthma correlate well with each other irrespective of total and specific IgE.

Sera of 31 patients infected with Clonorchis sinensis were examined using fraction 1 antigen by ELISA during a one-year observation. The results of ELISA with Igs, IgG and IgA demonstrated high sensitivity (100%, 100% and 90%) and specificity (100%, 100% and 87%). Sera specific Igs and IgG were significantly decreased in the 3rd month after treatment with praziquantel (25mg/kg body weight in one dose), and IgA was significantly decreased in the 1st month (paired t-test, p < 0.05). No eggs were found in the stool after treatment. Detection of sera specific Igs, IgG and IgA by ELISA was combined with stool examination to evaluate the effect of praziquantel and the completeness of the cure.
