The flow cytometry crossmatch in kidney transplantation.

1. Positive FCXM reactions were associated with sensitization in transplants with negative cytotoxic crossmatches. Recipients of regrafts, females, particularly those with previous pregnancies, and recipients with historical cytotoxic antibody reactivity were more likely to have FCXM detectable antibodies. 2. Primary nonfunction grafts were associated with a positive FCXM, but predominantly in those transplants involving female, older, or nontrauma donors. Nearly 40% of the FCXM positive transplants of these organs did not function during the first month posttransplant 3. Low 3-month graft survival rates were associated with a positive FCXM reaction, but once again this was seen with female, older, and nontrauma donor transplants. In addition, approximately 40% of FCXM positive transplants involving older or nontrauma donors that did survive had poor graft function at 3 months.

The Los Angeles Transplant Society.

For some 20 years a coordinated arrangement for sharing cadaver organs has been in place in Southern California. It's 11 transplant centers have performed 4,947 kidney transplants from 7,480 referred donors. There were 430 transplants done in 1985. The policy has been to keep one kidney and share the other within the pool. This has resulted in a better than average level of matching for HLA, and an overall better than average graft survival. The graft survival rates at the centers have been increasing yearly. Much of the improvement in graft survival resulted from the introduction of cyclosporine, but a summation of many factors contributed to a steady yearly increase. There are some 600 patients waiting for transplantation. With greater efforts in procurement of cadaver kidneys, especially from minorities, and continued collaboration between the transplant centers, it should become possible to transplant all those who are in need of a kidney.

Mediation of the antiproliferative effect of cyclosporine on human lymphocytes by blockade of interleukin 2 biosynthesis.

Normal human peripheral blood mononuclear cells (PBMC) were cultured with phytohemagglutinin-P (PHAP) and cyclosporine (CsA) to investigate the mode of action of CsA on cellular proliferation. CsA at 1 microgram/ml exerted a marked inhibitory effect on PBMC responsiveness to PHAP. An antiproliferative effect of CsA was observed at the inductive phase of the cell cycle, but the drug was ineffective when it was added to cultures 24 hr after stimulation. In parallel with this inhibitory effect interleukin 2 (IL-2) production was inhibited. In contrast, IL-2 receptor was expressed on the CsA-treated cells, and the antiproliferative influence of the drug was completely reversed by addition of highly purified human IL-2 to the CsA-treated cells. Exogenous IL-2, however, did not restore cellular capacity to produce IL-2. This study suggests that CsA acts by inhibiting IL-2 production (via blockade of IL-2 gene expression) rather than by preventing the expression of the IL-2 receptor.

Renal transplantation update.

Various factors affect the outcome of renal transplants in humans. Matching for HLA-A, -B, and -DR histocompatibility antigens improves survival rates for renal allografts from first cadaver donors. Zero-HLA-A- and -B-antigen-mismatched grafts and two-HLA-DR-antigen-matched grafts do better, although results differ depending on the recipient's primary renal disease. Pretransplant third-party blood transfusions significantly improve survival rates of cadaver donor allografts. The mechanism of this beneficial effect has not been identified; however, blood transfusions probably do not "select out" high responders among potential recipients by stimulating the production of lymphocytotoxic antibodies. Cyclosporine has been heralded as a potent, nonspecific immunosuppressive agent that will significantly improve renal allograft survival rates. The selectivity of cyclosporine's effect on T lymphocytes is advantageous; however, its side effects, especially nephrotoxicity, may limit its usefulness. Attention to the potential surgical complications of renal transplantation can significantly reduce morbidity and mortality.

Nonoliguric acute renal failure.

The course of nonoliguric acute renal failure (ARF) in 11 patients was analyzed. The possible etiology of the renal failure was multiple in all cases and did not differ from that seen in oliguric acute tubular necrosis (ATN). Other than the urine volume, which ranged from 510 to 2,325 ml/day, there was no major clinical or biochemical difference between these cases of nonliguric ARF and those described for oliguric ATN. Creatinine clearance, however, was higher than anticipated in oliguric ATN and ranged from 2.8 to 15.0 ml/min. There was a direct relationship between creatinine clearance and daily urine volume. The essential difference between oliguric and nonoliguric renal failure appears to be the lesser degree of renal damage in the nonoliguric form.
