[Associations between the renal tubular acidosis of primary Sjogren syndrome and the infection of Epstein-Barr virus: a preliminary study].
To explore the possible etiological associations between the infection of Epstein-Barr Virus (EBV) and the occurrence of renal tubular acidosis (RTA) of primary Sjogren's syndrome (SS), renal biopsies from both primary SS with clinical or subclinical RTA and controls were detected by using a monoclonal antibody against EBV early antigen P138 and a 32P-labelled EBV Bam W probe. As a result, cytoplasmic fluorescence staining of epithelial cells with the monoclonal antibody as described above was noted in all the seven renal biopsies from primary SS, and one out of two renal samples among them contained EBV DNA detectable by dot blot hybridization with Bam W probe. Whereas five control renal biopsies were all negative on the same methods of detection. Our study suggested that EBV has been of a lytic fate leading to active replication in the kidneys of patients with RTA of primary SS. Therefore, EBV may play an important role in the renal damage, especially resulting in RTA, of primary SS.
