[A study on the relationship between respiratory tract viruses antigen in peripheral blood mononuclear cells and their antibody from children with steroid-sensitive and simple nephrotic syndrome].

Objective: To explore whether respiratory tract viruses infection was involved in the pathogenesis of sterioid-senstive and simple nephrotic syndrome(SSSNS).

Methods: Using APAAP and ELISA, the authors assayed the expression of respiratory tract viruses antigen in peripheral blood mononuclear cells (PBMC) and the production of viruses antibody in serum from 20 cases of children with steroid-sensitive and simple nephrotic syndrome.

Results: The positive rate of viruses in the active stage group of SSSNS children increased (P < 0.05), compared with that in the remission group and the healthy control group. The positive rate of virus detection in SSSNS children was closely related with the quantity of urinary protein(P < 0.05). The positive rate of virus detection in the group with urinary protein > or = 50 mg/(kg.d) was higher than that in the group with urinary protein < 50 mg/(kg.d).

Conclusion: The onset of SSSNS may be related to the infection of respiratory tract viruses.
