ABSTRACT
OBJECTIVES:
Anti-glutathione S transferase T1 (GSTT1) antibodies, a type of non-HLA antibody, have been associated with chronic hepatic graft rejection. Despite the presence of this enzyme in the kidney, there are not enough studies on the development of anti-GSTT1 antibodies and their impact on renal grafts. Our objective was to evaluate the presence of anti-GSTT1 antibodies after renal transplant and their impact on graft outcomes. MATERIALS ANDMETHODS:
We conducted an ambispective cohort study. We performed real-time polymerase chain reaction to screen for GSTT1 alleles in 293 recipients and their donors. In null GSTT1 (GSTT1*0) genotype recipients of GSTT1-positive donors, the presence of anti-GSTT1 antibodies was evaluated using indirect immunofluorescence and Luminex assays, and their effects on graft function were evaluated. The median follow-up period was 54.3 months.RESULTS:
Of the 293 patients studied, 42 recipients (14.4%) with GSTT1-positive donors did not have the GSTT1 allele (GSTT1-positive donor/GSTT1*0 recipient). Using Luminex assay, we detected antibodies in 16 patients (38.1%), 12 of which were already present at the time of transplant. Of these cases, 37.5% with antibodies had undergone a previous renal transplant. Using indirect immunofluorescence, we found that only 12 patients tested positive, 4 at the time of transplant. Antibody presence did not effect graft glomerular filtration rates or graft loss at 1 year, at 2 years, or end of follow-up.CONCLUSIONS:
The presence of anti-GSTT1 antibodies is frequent in renal transplant GSTT1*0 recipients of GSTT1-positive donors but has no effects on graft outcome.
