Abstract
BACKGROUND
The massive resection of the small intestine leading to short bowel syndrome (SBS) deprives an organism of many immunocompetent cells concentrated in gut-associated lymphoid tissue, the largest immune organ in humans. We have aimed to access the influence of bowel resection on adaptive immunity in children, based on peripheral lymphocyte subsets and serum immunoglobulins.
METHODS
15 children who underwent bowel resection in the first months of their life and required further home parenteral nutrition were enrolled into the study. Based on flow cytometry, the following subsets of lymphocytes were evaluated: T, B, NK, CD4+, C8+, and activated T cells.
RESULTS
Statistically significant differences were found for the rates of lymphocytes B, T, CD8+, and NK cells. The absolute count of NK cells was lower in the SBS group than in the control group. Absolute counts of lymphocytes, lymphocytes B, T, CD4+, and percentages of lymphocytes CD4+, and activated T cells inversely correlated with age in SBS group.
CONCLUSIONS
Children with SBS do not present with clinical signs of immunodeficiency as well as deficits in peripheral lymphocyte subsets and serum immunoglobulins. The tendency of the lymphocyte subpopulations to decrease over time points out the necessity for longer follow- up.
