Abstract:
:To examine immune activation rate of interstitial and glomeruli infiltrating MNC in different conditions of human renal allograft function deterioration, 33 renal transplant biopsies were performed 1-30 months after transplantations. Forty-one patients observed were on immunosuppressives: Pr, Aza, CsA following renal transplantation from a living-related donor parent. The patients were divided according to their histologic diagnosis into the following groups: 1, 15 pts in acute rejection attack (AR); 2, 10 pts with cyclosporine nephrotoxicity (CsN); 3, 10 pts with chronic vascular rejecting kidney (ChR). A conventional histologic investigation and immunohistochemical analyses of CD3 and CD25 molecules were performed in groups 1-3. Spontaneous blastogenesis (SB) of peripheral lymphocytes was simultaneously determined and compared with the controls (C)-30 healthy people, and with patients with stable renal allograft function (S)-8 pts. The highest IL-2R expression on diffuse or focal dense MNC infiltrates in interstitium was observed during AR, without IL-2R+ MNC in glomeruli. Low to moderate focal interstitial infiltrates in damaged areas of renal parenchyma due to CsN, were IL-2R negative. In ChR, moderate IL-2R expression was observed on interstitial spare mild or focal dense MNC infiltrates with IL-2R expression present on glomeruli infiltrating MNC. Significant increases of SB values were recorded during the first week after transplantation and AR in comparison to C. The highest SB values were in ChR group. Values of SB in CsN and S were on the C and before transplantation levels.(ABSTRACT TRUNCATED AT 250 WORDS)
