Abstract

Renal biopsy (RBx) informs about kidney transplantation (KTx) prognosis. In our observational study the prevalence of histological anomalies and the prognostic role of CD45, vimentin (VIM) and periostin (POSTN) in KTx-RBx have been evaluated. One hundred forty-six KTx-RBx (2009-2012) were analysed for general histology and in immunohistochemistry for CD45, VIM and POSTN. Clinical data of the 146-KTx patients were collected at the RBx time (T0), 6 and 12 months before and after RBx. Follow-up time was 21 ± 14 months. Glomerulosclerosis was 20% glomeruli/biopsy. Tubular atrophy (TA), Interstitial infiltrate (I-Inf) and interstitial fibrosis (IF) were slight in 21–18% and 25%, moderate in 22–30% and 26% and severe in 30–18% and 28% of patients. Fifty-eight percent of patients had lesions compatible with IF-TA. CD45, VIM and POSTN correlated to each-other and to TA, I-Inf and IF. VIM and POSTN correlated to GS. CD45 and VIM correlated directly to renal function (RF) and 25(OH)VitD, while POSTN inversely to 25(OH)VitD. Thirty patients restarted dialysis (HD+). HD+ had lower T0-eGFR, and higher CD45, VIM and POSTN than HD−. POSTN resulted the strongest in discriminate for HD+ . CD45, VIM and POSTN correlate to each-other and predict graft outcome. POSTN was the strongest in discriminate for HD+. 25(OH)VitD might influence inflammation and fibrosis in KTx.
