[Food sensitization in children with Opisthorchis felineus invasion]
Aim:
To determine the mechanism of food sensitization in children with chronic Opisthorchis felineus invasion.
Patients And Methods:
During the epidemiological study the groups of patients (7-10 years) with chronic opisthorchiasis (n = 237) and children without chronic opisthorchiasis (n = 496) were formed. The investigation included interviewing of parents/guardians, measurement of total IgE, specific IgE to food allergens and component-resolved diagnostic, real-time PCR in stool samples.
Results:
The chronic opisthorchiasis invasion in children is associated with reduced risk of food sensitization, compared with non-infected group (9.7 vs 16.94%, OR = 0.53; 95% CI 0.31-0.88; p = 0.01). Opisthorchiasis of high intensity negatively correlated with increased level of specific IgE to food allergens in serum (OR = 0.46; 95% CI 0.24-0.91; p = 0.023). The association between level of total IgE and intensity of opisthorchiasis combinated with food sensitization was found. The sensitization to allergens class I (cyp c1, cor a11, gal d2, pru p3) is more prevalent in patients with opisthorchiasis, in uninfected children the sensitization to bet v1-homologues (mal d1, pru p1, cor a1, ara h8) is most common.
Conclusions:
The epidemiological data on the effect of the Opisthorchis felineus invasion on mechanisms of food sensitization in children were obtained.
