The aim of our study was cytokine and chemokine spectrum analysis of breast milk and determination of differences in their concentrations between the groups of mothers with and without history of allergic diseases.
Methods: Breast milk from 55 mothers was collected 4 days after the delivery and in the 1st, 3rd, 6th and 12th month of child’s age. 16 mothers with history of allergic disease and 39 mothers without any history of allergic disease were enrolled in this study. 23 cytokines and chemokines were detected semiquantitatively using protein microarray and certain cytokines, chemokines and growth factors (IL-4, IL-5, IL-6, IL-10, IL-13, IFN-gamma, MCP1, TGF-beta1, TGF-beta2 and EGF) were quantified by ELISA.
Results: We detected
high levels of the following cytokines in breast milk from non-allergic
mothers: GRO, IL-8, MCP-1, MCP-2, TGF-beta2, EGF and in breast milk from
allergic mothers: IFN-gamma, GRO, IL-8, MCP-1, TGF-beta2 and EGF. Comparing
the two groups, we observed statistically significant difference in
concentration of IFN-gamma in breast milk at 3 months of age (p=0.016),
which was higher in breast milk from allergic mothers.
Conclusion: Cytokine and chemokine spectrum of breast milk from allergic and non-allergic mothers is different. However, their biological role in breast milk often remains unknown. Protein microarray analysis and ELISA method seem to be suitable for cytokine and chemokine screening of breast milk. We plan to monitor babies of these mothers in future and we hope to find eventual predictive factors for later development of allergic disease.
