The correlation of immunologic derangement and juvenile recurrent parotitis: an investigation of the laboratory immunological observation.

BACKGROUND

Juvenile recurrent parotitis (JRP) is defined as recurrent parotid inflammation, generally associated with nonobstructive sialectasis of the parotid gland. In addition, the etiology remains unclear, probably immunologically mediated.

AIM: The purposes of the present study were to report the relationship between JRP and immune function from the measurement of the JRP patients' immunoglobulins and T-lymphocyte subset.

METHODS

Immunologic assay from 2014 to 2017 of 100 children diagnosed with JRP at Shanghai Ninth Hospital compared with the 100 normal children by age.

RESULTS

The CD4 level of JRP children aged >6 years was significant lower than the one of JRP preschool children (p < .05), while the IgG level was significant higher than the one of the JRP preschool children (p < .05). In comparison with the normal children, the value of CD8 T cells, immunoglobulin G (IgG), immunoglobulin E (IgE), immunoglobulin A (IgA) and C3 (p < .01) of JRP children was significant higher, while the value of CD4 T cells was lower (p < .01) in spite of age. What is more, the value of CD8 T cells of JRP preschool children was much significant higher than the one of the normal preschool children (p < .01).

CONCLUSION

The immune function of JRP patients may become disorder: the suppression cellular immune function and inadequate humoral immune expression.
