مستخلص: | Aim: The primary aim of the study was detection of subclinical acute rejection and borderline changes in protocol biopsies at 3 months after transplantation, and assessment of possible clinical and laboratory associations. Methods: Biopsy was carried out in 194 patients with stabilized graft function. Patients were treated with immunosuppressive regimen based on cyclosporine A (n = 34), tacrolimus (n = 152), or sirolimus/everolimus (n = 10). Samples were processed by standard paraffine technique, and stained according to laboratory protocol. All samples were tested by immunofluorescence or immunohistochemical procedures for C4d presence as a sign of humoral rejection. Results: Of 192 representative samples, subclinical acute rejection and borderline changes were found in 24 samples (12.5%). In patients with this finding, the mean serum creatinine was significantly higher (185.2 +/- 2.2 micromol/L), than in patients with normal finding (128.2 +/- 28.3 micromol/L) p < 0.001. Using the ROC curve analysis of serum creatinine, the cut-off point 170 micromol/L was found to discriminate normal findings from subclinical rejection and borderline changes. A significant correlation between acute rejections before protocol biopsy and subclinical acute rejections together with borderline changes in protocol biopsy was found. C4d positivity was found in 6 samples. Immunosuppressive therapy (cyclosporine versus tacrolimus) did not have any impact on subclinical acute rejections and borderline changes prevalence. Conclusions: The main conclusion of this study is a finding, that acute rejection early after renal transplantation and serum creatinine > or = 170 micromol/l at three months after transplantation are risks for development of subclinical acute rejection, even of humoral type, or borderline changes. |
