Altered reticuloendothelial function in long-term renal allograft recipients

G. Drivas, L. Pulman, P. R. Uldall and N. Wardle

Using the clearance of microaggregated iodinated human serum albumin reticuloendothialial system (RES) phagocytic function was tested in 48 long-term renal allograft recipients and was found to be defective at the time of testing in 70%. Depression of RES phagocytosis could be related to total steroid dosage in the previous year and to the patients liability to bacterial infections. Evidence from this test does not suggest an immunosuppressive effect of cytomegalovirus. However, three patients are discussed who have developed chronic active hepatitis that is not due to type B virus.
