Objective To investigate the expression and clonality of TCR V? subfamily T cell in 11 patients undergoing chronic hemodialysis before and after renal transplantation.Methods The CDR3 of TCR V? 24 subfamily genes were amplified in samples of peripheral blood mononuclear cells which were drawn before hemodialysis and at 20th day post-operatively. To observe the usage of TCR V? repertoire, the RT-PCR products were further labeled with fluorescent and analyzed by genescan technique for CDR3 size.Results (1) One patient was attacked by acute cellular rejection (ACR) and one suffered from delayed graft function (DGF) diagnosed by renal transplant biopsy. (2) 1-10 TCR V? subfamilies T cells could be identified before transplantation, and most of TCR V? subfamily T cells expressed as polyclonality. The most frequent expression of TCR V? genes was V?3. (3) Only 1-5 TCR V? subfamilies T cells could be detected post-operatively, most of them expressed as oligoclonality. The TCR V?3 subfamilies still were the most frequently expressed (in 9 cases). (4) There were no TCR V? subfamilies T cells before pulse of methylprednisolone, and were 5 subfamilies during pulse of methylprednisolone expressed as oligoclonality or biclonality, 2 subfamilies after ACR expressed as polyclonality. In DGF patient, there were 4 TCR V? subfamilies during DGF, and 5 following DGF.Conclusion (1) The significantly skew distribution of TCR V? subfamily T cells could be found in all patients with chronic renal failure and chronic hemodialysis. (2) Furthermore, the skewing distributions of TCR V? genes came to more significant at 20th day post-transplantation than before. (3) ACR might be closely associated with some special clones of TCR V? subfamily T cells, which subsided immediately after ACR. (4) The expression as polyclonality after ACR and DGF may indicate that the immune function partially was inclined to normalization even though immunosuppressed.

Objective Recurrence of local segmental glomerulosclerosis (FSGS) in 2 patients with renal allograft was reported.Methods A male child aged 15 years and a male adult aged 25 years with primary FSGS, who were subjected to cadaveric kidney transplantation, had a recurrent nephritic syndrome showing massive proteinuria, hyperlipidemia and hypertension respectively in 2 weeks and 18 months postoperatively, that was suspected a recurrent FSGS. The child immediately was treated with Benazepril hydrochloride, 30?mg /day plus high dosage of Prednisolone ( 1?mg /kg every day) for 6 weeks, but proteinuria did not to be ameliorated. The adult was treated with high dosage of Prednisolone ( 1?mg /kg every) and Tripterygium wifordii for 12 weeks, but the syndrome was not improved. Results Two patients had recurrent FSGS according to renal biopsy revealing characterized by similar features: diffuse effacement of foot processes on electron microscope, segmental or focal sclerosis under light microscope and IgM, IgG, C3 deposits. The therapy of plasmapheresis as well as high dosage of Benazepril hydrochloride was added to institute respectively for continuous 3 sessions with removal of 1.5 volume plasma ( 1 200?ml of plasma) in the child and successive 6 sessions with removal of same volume ( 3 000?ml of plasma). The child's proteinuria had a significant reduction from 8.29?g /day to 4.52?g /day after a week post pheresis, that kept 4.52 ~ 5.56 ?g/day with stable creatitine (180~200??mol/L) following 18 months. The adult's proteinaria obvious decreased from 4.68?g /day to 1.50?g /day after plasma exchange a week and keeping decline to 1.06?g /day with normal renal function following 12 months. Conclusion FSGS may immediately be recurrence in pediatric renal transplants. The mechanism of recurrent FSGS may be associated with excessive glomerular filtration, circulating factor altering glomerular permeability, injection of anti thymocyte and lymphocyte immunoglobulin, and hyperlipidemia. Plasmapheresis in combined with ACE inhibitor can reduce proteinuria significantly rather than a single ACE inhibitor.
