Abstract Objective To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection. Methods A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (n=78) and breast milk HCMV negative (n=57). According to the median breast milk HCMV-DNA load, the infants in the breast milk HCMV positive group were further divided into two subgroups: high viral load and low viral load (n=39 each). Related indicators were compared between the breast milk positive and negative HCMV groups and between the breast milk high viral load and low viral load subgroups, including the percentages of peripheral blood lymphocyte subsets (CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells), CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load. Results There were no significant differences in the percentages of CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells, CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load between the breast milk HCMV positive and HCMV negative groups, as well as between the breast milk high viral load and low viral load subgroups (P>0.05). Conclusions Breastfeeding with HCMV does not affect the immune function of infants with HCMV infection.
