Improved graft survival is accompanied by complications which interfere with the long-term function of the allograft. Recurrence of the primary renal disease in the graft is well recognized and is found in 10 to 20% of all recipients; however, graft loss due to recurrent disease is reported in less than 5% of all cases. The most frequent cause of recurrence is glomerulonephritis: Membrano-proliferative GN type II, IgA nephritis and focal sclerosis are frequently observed. Among metabolic disorders linked to graft disease, diabetic nephropathy has to be mentioned first. Primary oxalosis is a rare disorder, but it is related to a very high risk of recurrent disease in the transplant. Combined kidney-liver transplantation seems to offer a valuable alternative for these patients. The high risk of recurrence of certain diseases, i.e. membrano-proliferative GN type II, focal-segmental glomerulosclerosis, primary oxalosis, should prevent living donation. In addition, there are some reports suggesting that living-related donation might increase the recurrence rate of hemolytic-uremic syndrome, membranous GN and Schönlein-Henoch purpura. Recurrent disease might not only affect the outcome of the transplant, but can provide insight into the nature and pathogenesis of the primary disease. Currently there are no conclusive reports indicating that chronic immunosuppression, especially cyclosporin-A treatment, reduces recurrence rates; however the clinical course might be ameliorated.
Expression of fibronectin and vitronectin receptors was studied in normal human kidney tissues and renal tissue biopsies from patients with several types of glomerulonephritis. Immunofluorescent staining of the normal kidneys showed that fibronectin receptor was present along the glomerular capillary walls, and that vitronectin receptor was present in the vessel walls, but was almost absent from the glomerulus. In kidney tissues biopsied from patients with various renal diseases, expression of fibronectin and vitronectin receptors was correlated with increase in the mesangial expansion. Expression of these receptors was decreased in the sclerosed area and hyalinized glomeruli compared with normal tissues. Fibronectin and vitronectin receptors were occasionally colocalized in the glomeruli with fibronectin and vitronectin, respectively. In situ hybridization showed that fibronectin receptor mRNA and vitronectin receptor mRNA were expressed in the diseased glomeruli. These findings indicate that expression of fibronectin and vitronectin receptors was altered in human glomerulonephritis, and that integrin expression may be important in cell-matrix interaction in the diseased glomeruli.
