Immunophenotyping of mononuclear cell infiltrates associated with renal disease.

Twenty-eight frozen renal biopsy specimens with a marked mononuclear cell interstitial infiltrate (MCI) were analyzed with monoclonal antibodies and a biotin-avidin peroxidase technique to define the surface phenotype distribution of the infiltrating cells. Twelve cases were diagnosed as tubulointerstitial nephritis of acute and chronic presentation, of unknown cause in 5 cases or secondary to multiple myeloma or drug reactions. Sixteen cases occurred in primary and secondary glomerulonephritis, 3 cases being associated with lymphoproliferative disorders. The results showed a remarkable heterogeneity of the MCI composition, even in cases with similar clinical and pathological findings. Namely, the T cells accounted for the majority of the infiltrating cells in most cases but a variable predominance of the T cell subsets Leu3 and Leu2 was observed. B cells and monocytes were also prominent in some cases. Such differences in the MCI composition may indicate the activation of different mechanisms of tissue damage, or a different phase of the renal disease. In the three cases of glomerulonephritis associated with lymphoproliferative disorders, the malignant origin of the MCI was demonstrated in one case, while in the remaining cases it was excluded.

Influence of technical factors and different immunosuppressive regimens on kidney graft survival. Retrospective analysis on 300 kidney transplants.

300 patients underwent kidney transplantation. Uretero-neocystostomy was performed by means of the Politano-Leadbetter technique in the first 185 patients and direct ureterovesical anastomosis in the other 115 patients. Immunosuppression included conventional therapy (steroids, antilymphocyte globulins, azathioprine) and the association cyclosporine A and steroids. Retrospective analysis on these 300 patients indicates that the improved 1 year graft survival rate (85% vs 64%) we observed in the latest years has depended to the same extent, on improved surgical technique and on advent of cyclosporine A in our therapeutic protocols. Cyclosporine A at low starting doses immediately adjusted on whole blood trough levels (200-400 ng/ml) proved to be superior to other therapeutic schedules reported in this study (1-year graft survival rate: 94% vs 84%-73%). Direct ureterovesical anastomosis was characterized by a net reduction of urologic complications (2.5% vs 9.7%).

Thromboendarterectomy (TEA) in the recipient as a major risk of arterial complication after kidney transplantation.

The authors analyze a series of 383 kidney transplantation pointing out the role of recipient's vessels atherosclerosis in the determination of vascular complication of the kidney graft. Three groups were considered. The first included 55 patients which required TEA for severe atherosclerotic lesion of the anastomosed vessels. The second group included 305 patients who didn't required TEA; the third group was of 20 patients who received a graft with multiple arteries which required more than one anastomosis. A significative higher rate of arterial complications was evident in the first group (p less than 0.001). Within this group the end to end arterial anastomosis was more frequently associated to thrombosis or stenosis than the end to side one (p less than 0.05). Kidney with multiple vessels also presented with an higher rate of complications (p less than 0.05).
