THE EFFECT OF POLYIMMUNE GAMMA-GLOBULIN FOR PROPHYLAXIS AGAINST REACTIVATION CYTOMEGALOVIRUS-INFECTION IN KIDNEY AND KIDNEY PANCREAS TRANSPLANT RECIPIENTS

Cytomegalovirus (CMV) remains the most important infection in the renal transplant recipient. Few data are available that provide guidance for approaches that seek to reduce the reactivation of latent disease after transplantation. To test the efficacy of polyimmune gammaglobulin in kidney and kidney/pancreas transplantation, consenting recipients with serologic evidence of previous CMV disease were randomized to receive i.v. polyimmune gammaglobulin (500 mg/kg) within 3 days of transplant with 250 mg/kg at weeks 1, 2, 4, and 6 or no prophylaxis. Both groups received identical induction and rejection immunosuppressive therapy. Polyimmune gammaglobulin prophylaxis reduced CMV reactivation infections. The incidence of reactivation infections was half in patients receiving Nashville/rabbit antithymocyte serum (N/R-ATS) compared with those receiving monoclonal anti-CD-3 therapy. Patients receiving polyimmune gammaglobulin along with N/R-ATS had an incidence of infection ot only 10%. Reactivation infections were twice as common in patients who had primary nonfunction and nearly three times as common in patients with acute rejection. Both risk factors were associated with longer anti-T-cell therapy. Polyimmune gammaglobulin prophylaxis should be considered in transplant patients with previous CMV exposure who will be receiving prolonged anti-T-cell therapy because of acute rejection or primary nonfunction.
