THE CLINICAL USE OF ANTILYMPHOCYTE GLOBULIN IN RENAL HOMOTRANSPLANTATION' Department of Surgery, University of Colorado School of Medicine SUMMARY Twenty patients were treated with antilymphocyte globulin (ALG) which was prepared from the serum of immunized horses. The ALG was used as an adjuvant to azathioprine and prednisone and its use limited to 4 months. The surviving patients are now 1 to 7 months post- operative. There was 1 death, the consequence of a technical accident. The function in the remaining 19 patients is excellent, despite reduced doses of azathioprine and especially prednisone. Biopsies were obtained in the first 8 consecutive cases from 108 to 145 days after operation. There was no evidence in the specimens of either Masugi-like or se- rum sickness nephritis. Since June 1966, all patients receiving renal homotransplantation at  the Colorado General and Denver Veterans Administration Hospitals have been treated with heterologous immune globulin, prepared from the serum of horses which had been immunized with human spleens, thymuses, and lymph nodes. The steps which led to the clinical use of antilymphocyte globulin (ALG) were based on the pioneering studies in rodents by Waksman (16), Woodruff (13), Gray (3)  , Monaco (8 ) ,  Jeejeebhoy (6) , and Levey and Medawar (7) and upon our own previously reported investigations in dogs (4,5,10). The postoperative follow-up of the first 20 cases in this test series is of course too brief to allow conclusions about the influence that treatment with ALG will have upon the ultimate course of these patients. Evidence has been ob- tained, however, that such foreign protein therapy is of at  least short term value, and that i t  can be given without prohibitive toxicity for a period of several months as will be summarized in the present report. A far more detailed analysis of these cases has been published elsewhere, as well as an account of ALG therapy in patients with late failing homografts (11). METHODS ALG administration was planned within guidelines established from animal studies which included the following considerations: (I) ALG when used alone does not prevent or even delay rejection of all canine homografts (1, 10) ; (2) 'Aided by Grants AM 06283, AM 06344, H E  07735, AM 07772, A1 04152, FR 00051 and F R  00069 from the United States Public Health Service, and by a grant from the Medical Research Council of Great Britain.

Because of the above information, ALG was used only as an  adjuvant agent, in combination u ~ i t h  azathioprine and prednisone. I n  the usual case, daily in- jections were started 5 days before operation, continued each day for 10 to 17 days afterwards, then every other day for 2 weeks, twice a week for 2 ~nonths  and once a week for 1 inonth (Fig. 1 ) .  Two patients who had anaphylactic reactions had therapy stopped prematurely. The ALG had a leukoagglutinin titer of 1:4096 to 1:32, 768, and a protein concentration of 4.6 to  9.3 gn1/100 ml. Individual intramuscular injections were 1 to 5 1nl. The weekly protein dose per kg was 14-50 mg a t  the beginning and 2-6 ing a t  the end of therapy. -160 - 140 -120 - 60 - 40 Ccr (ml/min) ' 2 5  (mgmlday)  loo TIME IN DAYS FIGURE 1. Course of a patient who received ALG therapy before and after renal homotransplantation. The homograft was provided by a brother. There has never been rejection. The prednisone therapy was started after 40 days because of the increases in hemagglutinin and precipitin titers. Note the subsequent fall in these measures despite continuation of globulin injections. Henlagglutinin titers against sheep red blood cells and precipitin titers were nionitored as indices of antibody formation against the foreign protein. The first 8 patients had open homograft biopsies from 108 to 145 days after trans- plantation. Azathiopririe and prednisoiie were given as described in detail elsewhere ( l l ) ,  in a schedule wliich called for the niaxirnum doses of the former drug which were possible without producing leukopenia, and the smallest steroid doscs which were compatible with stable renal function. The effcctiveness of therapy was judged by analyses of tlle death rate, the quality of honiograft excretion, and the quantities of standard in~nlunosuppressive agents necessary t o  retain this function. Morta lz ty .  The 20 patients have hecri followed for 1 to  7 months. The oper- ations were 5% to 7 months ago in the first 8 cases, 2 t o  4 months in the next 8, and 4 to 6 weeks in the last 4. Thcre has only been 1 death (Fig. 2) ,  the four- teenth patient in the group, from complications stemming directly from a tech- nical accident. Nineteen of the recipients were donated kidneys hy blood relatives on essen- tially random selection basis; parents in 5 instances, siblings in 13, and a iliatcrnal uncle in the other. The twentieth patient received a cadaveric homo- graft from a donor who was shown by the teams of van Rood, Amos, and Tera- saki, wlio were working in Denver a t  the tinic, to  have a higli degree of antigen incompatibility with the recipient. Because of the preponderance of related cases, the mortality was coiriparccl to that  with 3 sequential past series of con- sanguineous tra~~splantatioris a t our iristitutions (Fig. 2 ) .

P~ozction. The 19 surviving patients all have good rcnal function. A weck by week vicw of the average creatinine clearance of the first 8 consecutive cases for the first 5 months is shown in Figure 3. Function for the first 2 months was adequate, but after this, the cleararlces further improved. At the time of their biopsies from 108 to 145 days post-transplantation the various measures of rcnal function%were blood urea nitrogen 26.7 * 5.5 (S.D.) mg/100 ml, plasma creatiiliile 0.92 2 0.2 (S.D.) mg/100 ml, creatinine clearance 97.4 * 21 (S.D.) ml/min, inulin clearance 61 * 12.6 (S.D.) ml/min and PAH clearance 349 + 66 (S.D.) ml/min. The filtration fraction was 17.9% * 3.3% (S.D.). Urine protein concentration was 5.4 * 3.6 (S.D.) mg/100 ml. The clearances were performed by Dr. David A. Ogden who also studied all 8 donors a t  the same time. The average function in the donors was not significantly different from that in the recipients. 1104 TRANSPLANTATION Vol. 5, il'o. 4 For comparison, the average creatinine clearances are shown (Fig. 3) for those patients who lived for a t  least 5 months in each of the 3  preceding series of consanguineous transplantations; the elimination of early dcaths in the ret- rospective control series created a bias since only data from the best cases were retained. Nevcrthcless, the mean clearances from the third nionth onward were greater in the globulin treated group. Immunosuppression. The quantities of azathioprine per kg were less than in any of the previously treated series (11). However, the most striking de- clines were in the steroid doses, which were approximately half of those in the 3  previous groups of patients who were selected as controls by virtue of their ability to survivc for a t  least 5 months (Fig. 3 ) .  These data,  together with those from the preceding section, suggest that  the reduction in the stringency of therapy with standard immunosuppressive drugs was not paid for by an  increased injury to the homograft. Ejfect of lymphocytes. There was no statistically significant difference in the degree of postoperative lyinphopenia in the globulin-treated as opposed to the 3 retrospective control series. Toxicity. Pain and tenderness a t  the injection sites and fever were observed in virtually every case. Four of the 20 patients have had anaphylactic re- actions whicli lasted for only a few minutes; in 2 of these cases, injections were continued for an additional month or longer. Increases in precipitin titers and antishcep red cell titers eventually occurred in every patient, but tended to  regress either spontaneously or with the addition of steroids. The homograft biopsies from the first 8 cases are fully described elsewhere (11). None were completely normal, but there was evidence of permanent damage in only one case where narrowing of several interlobular arteries was found. A portion of each of the biopsies was examined by Drs. Beatrice C. Seegal and Konrad C. Hsu of Columbia University, New York, and by Dr. Giuseppe A. Andres of the University of Rome, Italy, using fluorescein-labeled and fer- ]-itin-conjugated antihorse protein antibodies to detect the presence or absence of equine protein in these kidneys. None was found. DISCUSSION Experience with these cases has been distinctly encouraging in 2 respects. First, the early course after human renal hon~otransplantation seems to  have been improved by the addition of ALG to the therapeutic protocol. There has only been 1 death in the 20 cases, and tha t  fatality followed a serious technical accident. Renal function has been as good as in any comparable group of pa- tients previously treated in Denver, and in the cases with the longest follow-up i t  is distinctly better. These results have been obtained with smaller quantities of standard immunosuppressive agents, particularly of prednisone. Secondly, the use of ALG has been possible without prohibitive morbidity. Anaphylactic reactions were seen in 20% of the patients but these were rela- tively minor, and in 2 of the 4 cases a number of subsequent injections were J~ t ly ,  1967 STARZL ET AL. 1105 given. Two other fearcd iminunologic reactions, each with a distinctive immu- nologic mechanism, would have been detectable in the homograft biopsies since both cause intrarenal deposits of heterologous protein which can be iden- tified for many months afterwards with specific labeled-antibody techniques (2 ,  9). However, there was no evidence either that the ALG antibodies had reacted directly with the renal tissue (Masugi nephritis) or that these kidneys were the passive receptacles of soluble antigen-antibody complexes (serum sickness nephritis).
