The effect of hyperimmune globulin for the prevention of cytomegalovirus (CMV) infections following bone marrow transplantation (BMT) was evaluated in 21 children with various diseases and compared to a historical group of 23 children without prophylaxis. A higher incidence of interstitial pneumonia (19%) as well as CMV-associated infections with or without pneumonitis (29%) could be demonstrated in patients with CMV-prophylaxis as against the rate of interstitial pneumonia (4%) and CMV-infections (8%) in children without prophylaxis. This surprising observation was very likely due to selection of patients with high risk features and higher incidence of GVHD in the prophylaxis group. The analysis of patients with prophylaxis failure shows a low CMV-infection rate in initially seronegative marrow recipients and a high risk for CMV-infections in seropositive patients. Therefore, even though CMV-infections could not be completely abrogated, hyperimmune globulin administration might have reduced CMV-complications in seronegative patients. In CMV-seropositive marrow recipients, however, this type of prophylaxis remains unsatisfactory in preventing severe CMV-infections caused by virus reactivation.

Twenty-three children with haematological malignancies and a poor prognosis underwent bone-marrow transplantation. Thirteen children had acute lymphoblastic leukaemia, eight had acute nonlymphoblastic leukaemia, one had chronic myeloid leukaemia and one had malignant histiocytosis. One child was in relapse at the time of transplant and 22 were in first or subsequent remission. Before transplantation all patients received cyclophosphamide (60 mg/kg) on two consecutive days followed by total body irradiation given as a single dose of 10 Gy at 0.18 Gy/min (one patient) or 0.07 Gy/min (three patients), or as a fractionated dose of 10-12 Gy at 0.07-0.1 Gy/min (19 patients). One child with malignant histiocytosis also received two doses of etoposide (5 mg/kg). Methotrexate was given after transplantation to prevent or modify graft-versus-host disease (GVHD). One patient who received a transplant in relapse died early from overwhelming bacterial sepsis. Twenty-two patients engrafted, and of these 11 developed acute GVHD; five developed chronic GVHD; seven developed interstitial pneumonitis, with four deaths; and five relapsed between three and 12 months after transplantation, with three deaths. Fifty-nine per cent (13/22) of patients who received a transplant during remission remain in continuous complete remission and 68% (15/22) have survived for a median of 18 months (range, four to 73 months). Bone-marrow transplantation that is undertaken during remission of disease offers a prolonged disease-free survival in selected childhood malignancies.

Ten children between the ages of five and fifteen years old with leukemia (two with acute nonlymphocytic leukemia in first remission, four with acute lymphocytic leukemia in first or second remission, one with acute lymphocytic leukemia in relapse, and one with chronic myelocytic leukemia in chronic phase), malignant lymphoma (one) or severe aplastic anemia (one) were given transplants from HLA-matched or mismatched family members between March, 1982 and April, 1984. Two patients died of leukemia relapses on days 107 and 257 following transplantation. One patient died of cardiac failure on day 157. One patient who received HLA-mismatched marrow from his father died of pulmonary edema and acute graft versus host disease on day 32. Six are alive 268-843 days post transplantation. None of the ten patients developed interstitial pneumonia due to cytomegalovirus which is one of the major causes of death reported in other published studies.

In an attempt to reduce the incidence of lethal cytomegalovirus (CMV) interstitial pneumonitis after allogenic bone marrow transplantation 49 patients were randomized in a multicenter controlled study to receive either CMV-hyperimmune globulin or a control immune globulin with low anticytomegalovirus titer. Immune globulin was administered intravenously 6 times with 20 days interval, starting on day 7 before transplantation. Patients receiving CMV hyperimmune globulin or control immune globulin were comparable with regard to age, diagnosis, pretransplant anti-CMV titer, incidence of graft-versus-host disease and transfusions. In each group, the incidence of histologically proven CMV interstitial pneumonitis during the first 110 days post BMT was recorded. Six of 23 patients in the control group versus 1 of 26 in the CMV hyperimmune globulin group died of CMV interstitial pneumonitis (p less than 0.05). No significant effect on idiopathic pneumonitis or survival was observed.

Interstitial pneumonia is a major determinant of early and late morbidity and mortality following bone marrow transplantation. Among 952 patients receiving allogeneic marrow grafts in Seattle, 35% developed interstitial pneumonia within 100 days of transplant. Development of early cytomegalovirus (CMV) or idiopathic interstitial pneumonia was infrequent in patients with aplastic anemia prepared only with cyclophosphamide. Use of total body irradiation (TBI) in the transplant preparation, increasing patient age, pretransplant seropositivity for CMV antibody and post-transplant development of graft-versus-host disease (GVHD) all increased the risk of CMV pneumonia. Late interstitial pneumonia was studied in patients with chronic GVHD. Among 198 patients with extensive chronic GVHD, 31 episodes of interstitial pneumonia (seven idiopathic, six CMV, six pneumocystis, five miscellaneous and four unknown causes, and three varicella-zoster) were observed 3-24 months after transplant. In untreated patients with chronic GVHD, 15% developed late interstitial pneumonia. Patients with chronic GVHD who received prednisone +/- azathioprine as immunosuppressive therapy and trimethoprim sulfamethoxazole for infection prophylaxis had an 8% incidence of interstitial pneumonia. Patients with chronic GVHD given immunosuppressive treatment without trimethoprim sulfamethoxazole prophylaxis had a 28% incidence of interstitial pneumonia. Trimethoprim sulfamethoxazole significantly reduced the incidence of late interstitial pneumonia in patients with chronic GVHD (p = 0.001).

The effects of high doses of polyvalent intravenous immune globulin given for prophylaxis of cytomegalovirus infection and interstitial pneumonia in recipients of allogeneic marrow transplants were evaluated in a randomized controlled trial. Both symptomatic cytomegalovirus infection (21% compared with 46%, p = 0.03) and interstitial pneumonia (18% compared with 46%, p = 0.02) occurred less frequently in the recipients of intravenous immune globulin than in control patients. Prophylactic intravenous immune globulin was also associated with a lower incidence of graft-versus-host disease (34% in recipients compared with 65% in controls, p = 0.01), but its reduction in rates of interstitial pneumonia was independent of graft-versus-host disease and occurred in both patients with and without graft-versus-host disease. The high doses of immune globulin were well tolerated. Prophylactic intravenous immune globulin can modify the severity of cytomegalovirus infection and prevent interstitial pneumonia and possibly graft-versus-host disease in patients having allogeneic marrow transplantation.

Pulmonary interstitial infiltrates developed in a 22-year-old female after bone marrow transplantation (BMT) for acute lymphoblastic leukemia (ALL) in second remission. She was receiving prednisone for graft versus host disease (GvH). There was some evidence of cardiac failure, but the primary diagnosis was that of cytomegalovirus (CMV) pneumonia, which resolved. Recurrent infiltrates were associated with the appearance of fat emboli in the pulmonary capillaries. There was little histological evidence of CMV pneumonitis, although other tests confirmed persistent infection. The patient recovered after further treatment directed at CMV infection and cardiac failure with a modest reduction in steroid dose. Most previous descriptions of pulmonary fat embolization (PFE) in immunocompromised patients have been derived from autopsy studies, and the majority of patients have received steroid therapy. The present case illustrates that PFE may complicate or contribute to the picture of interstitial pneumonitis (IPN) in the BMT recipient and that this syndrome may be reversible.

Fifteen patients with high-risk leukaemia were given T-cell depleted marrow transplants from HLA non-identical related donors. They were treated with a combination of total body irradiation (TBI), high-dose cytosine arabinoside (Ara-C) and high-dose melphalan in an attempt to prevent a host-versus-graft reaction. Antilymphocyte globulins were given prior to transplantation for additional immunosuppression to 13 patients and in-vivo monoclonal antibody anti-human LFA1 to two. Engraftment and chimaerism assessed by HLA typing were achieved in 14 patients. Seven developed acute graft-versus-host disease (two fatal), one failed to engraft. Six patients died in complete remission from cytomegalovirus (CMV) interstitial pneumonitis and three remain alive in complete remission 2, 3 and 13 months after transplant. We conclude that aggressive immunosuppression allows for sustained engraftment of T-cell depleted HLA non-identical marrow. The incidence and severity of GVHD are acceptable and CMV pneumonitis remains the major problem.

The probability of long term survival for allogeneic graft patients was 63% for ALL, 60% for ANL and 47% for CML in the 1st remission or 1st chronic phase of each leukemia. The major causes of death were interstitial pneumonia, relapse of leukemia and infections. On relationship of GVHD and the long term survival, the probability of 5 years survival was 38%, 47% and 25% in grade 0, I and II-IV of acute GVHD respectively. The difference might be due to that of relapse rate of leukemia. And the relationship between the relapse rate and GVHD, the patients with both of acute and chronic GVHD showed the lowest relapse rate 15.9%, the patients without GVHD showed the highest relapse rate 37.8% and the patients with either of GVHD showed the rate of between those of two groups. This may suggest that GVHD both acute and chronic might have an ability that can suppress the relapse of leukemia, i.e. GVL reaction. Interstitial pneumonia occurred in 32% of allograft patients and was often lethal complication (53%). Among many of prophylaxis tested, the followings were effective, a lower dose rate of total body irradiation, the selection of CMV-seronegative platelets donor, and the prophylactic administration of anti-CMV high titer globulin. Colony stimulating factor of human urine was also effective for shortening the granulopenic period after transplantation to prevent severe infections.

The present report summarizes our experience in applying a new approach in bone marrow transplantation for the treatment of beta-thalassemia major. Ex-vivo pretransplant T-lymphocyte depletion with CAMPATH-1 was used for prevention of acute and chronic graft versus host disease and total lymphoid irradiation was added for the conditioning regimen for abrogation of potential rejection of T-cell depleted marrow allografts. Ten patients with homozygous beta-thalassemia major were 9-48 months of age (median 18.5 months) and received HLA-identical allogeneic T-cell depleted marrow after treatment with total lymphoid irradiation, busulfan and cyclophosphamide. Seven patients are alive and free of disease, 3-46 months post-transplantation. The actuarial probability of survival and of disease-free survival at two years was 70%. Three patients died: one of intracranial hemorrhage post-transplantation, one from busulfan interstitial pneumonitis, and one who rejected the first graft and developed fatal chronic graft versus host disease after a second transplant. Seven patients are alive and well with follow-up of 3-45 months, with no signs of acute or chronic GVHD. We conclude that T-cell depleted bone marrow transplantation is indicated for homozygous transfusion dependent young patients with beta-thalassemia who are minimally transfused, particularly in areas where optimal conventional therapy is not feasible.
