[The clinical significance of albuminuria in renal transplantation].
Urinary excretion of albumin was measured after renal transplantation in 37 patients who received cyclosporine quadrotherapy (cyclosporine A, azathioprine, prednisolone and antilymphocytoglobulin). In 26 patients with a favorable clinical course, daily urinary albumin level increased significantly on the first operative day. Subsequently, it decreased gradually, and remained at about 40mg/day after 3 weeks. In these patients, the urinary albumin level did not correlate with blood pressure, whole blood cyclosporine level, serum creatinine level nor urinary enzyme level, i.e. beta 2-microglobulin, NAG, gamma-GTP. As for correlation between the urinary albumin level and biopsy findings in 21 patients who underwent renal graft biopsy, the urinary albumin level was significantly increased in 5 patients with high degree of lymphocyte infiltration in the renal graft as compared with 16 patients with low degree of infiltration. However, there was no significant correlation between the urinary albumin level and the degree of tubular damage. In 4 patients of allograft rejection, a clinical course was reflected better in the albumin level than in the urinary enzyme level, these results show that the measurement of urinary albumin is a useful clinical examination to evaluate the allograft rejection of renal transplantation in cyclosporine era.
