Increasing age has been reported to be a poor prognostic factor for survival after bone marrow transplantation. We evaluated causes of death and frequency and type of complications after marrow grafting in 24 syngeneic and 39 allogeneic recipients who were 45 to 68 years old at the time of transplant. Most patients were in an advanced stage of hematologic malignancy. Among patients given syngeneic transplants, actuarial disease-free survival at 7 years is 20%. The major causes of death were relapse of leukemia and idiopathic interstitial pneumonia. Among allogeneic recipients, 9 (23%) are currently alive, and actuarial disease-free survival at 7 years is 11%. Cytomegalovirus pneumonia and septicemia were the most frequent causes of death. Patients over 50 years of age had the poorest survival rate (1/13), but many of these were transplanted in an advanced stage of their disease. However, among 12 patients transplanted while in remission or at an early stage of their disease, 5 are surviving 65 to 1,160 days after transplantation, with an actuarial survival rate of 22% at 3 years. This is in contrast to those who received their transplant in relapse: 2 out of 20 patients (10%) became long-term survivors, with a probability of survival of 15% at 3 years. The actuarial incidence of grade II through IV acute graft-v-host disease (GVHD) was 30% for allogeneic recipients 45 to 50 years of age. This was not significantly different from the incidence in younger patients. In patients 51 to 62 years of age, the actuarial incidence of acute GVHD was 79%; however, this group included three partially HLA-mismatched transplants. Ten of 15 patients surviving at least 3 months developed chronic GVHD. These results suggest that marrow transplantation is feasible and should be considered in patients over 45 years, especially if recipients are in good clinical condition and are at an early stage of their disease, such as the chronic phase of chronic myelogenous leukemia and preleukemia. For patients more than 50 years of age, allogeneic marrow grafting cannot presently be considered first-line therapy.

One hundred twelve patients with hematologic malignancies underwent marrow transplantation from HLA-matched sibling donors and were randomized to receive either prophylactic granulocyte transfusions (PG, 67 patients) or prophylactic systemic antibiotics (PSA, 45 patients) as prophylaxis against nosocomial infections. Patients were treated in conventional hospital rooms and studied until day 100 post-transplant. For the entire study period, 26 patients (39%) in the PG group developed septicemia compared to 15 patients (33%) in the PSA group. Twenty-eight patients (42%) in the PG group developed local major infections compared to 19 patients (42%) in the PSA group. Ten patients (15%) in the PG group developed viral interstitial pneumonitis compared to 6 patients (13%) in the PSA group. None of these differences were statistically significant. There was no difference in the incidence of bacterial or fungal infections or viral interstitial pneumonitis between the two groups during the granulocytopenic or post-engraftment period. There was no difference in the incidence and severity of graft-versus-host-disease (GVHD). Inability to carry out the prophylaxis was frequent in the PG group, with complications necessitating discontinuance of transfusion in 24% of the recipients and 13% of the donors. The use of PG as an infection prophylaxis modality in marrow transplantation is not supported by this study, as it is difficult to carry out and because PG did not show any advantage over the use of PSA in preventing nosocomial infections.

Sixty-five children with acute lymphoblastic leukemia (ALL) underwent allogenic bone marrow transplantation (BMT) from an HLA identical donor, following cytoreduction with cyclophosphamide and total body irradiation (TBI): 15 were transplanted in 1st remission, 43 in 2nd and 7 in 3rd or in 4th. The Kaplan Meier estimate of surviving disease free at 4 years post BMT was 49.9% and the probability of continued remission at 4 years was 63.3%. Fourteen patients relapsed between 90 and 690 days (mean: 240 +/- 88) post BMT. The other causes of BMP failure included: graft versus host disease, veno-occlusive disease and sepsis. No interstitial pneumonitis has been reported. Patients who had a relapse while on chemotherapy had a higher probability of relapse than those who had a relapse while off therapy (p less than 0.01). We conclude that allogeneic BMT is the treatment of choice for children with ALL in second hematologic remission, the interval between diagnosis and first relapse being the most significant prognostic factor. Patients with poor prognosis might benefit from a more intensive chemotherapy/total body irradiation schedule or a BMT earlier in the course of their disease.

In a study of the outcome of marrow transplantation in patients with advanced thalassemia, 40 patients with homozygous beta-thalassemia who were 8 to 15 years of age (median, 10) received HLA-identical allogeneic marrow after treatment with busulfan and cyclophosphamide. Twenty-eight of the 40 patients were alive and free of disease 260 to 939 days after transplantation, and 2 patients were alive with thalassemia 372 and 1133 days after transplantation. The actuarial probabilities of survival and of disease-free survival at two years were 75 percent and 69 percent, respectively. Ten patients (25 percent) died. Three died of cardiac failure, interstitial pneumonitis, or septicemia within 14 days of transplantation. Three died of infectious complications associated with acute graft-versus-host disease at 46 to 97 days, and two died of infectious complications of chronic graft-versus-host disease at 249 and 290 days. Two patients had transplant rejection and died with marrow aplasia 115 and 192 days after transplantation. One patient had rejection after four months and while the marrow was aplastic underwent a successful second transplantation; the patient was alive without thalassemia 624 days after the first transplantation. The actuarial probability of grade 2 or higher acute graft-versus-host disease in the 32 patients with initial sustained engraftment was 35 percent. Three patients had chronic graft-versus-host disease, which was fatal in two and still active on day 710 in the third. We conclude that bone marrow transplantation can potentially save patients with advanced thalassemia from an otherwise inexorable progression to death from the complications of blood transfusions. The ultimate outcome in this group of patients must await a longer follow-up.

Isoimmunisation to platelet and lymphocyte antigens occurred during a woman's seven pregnancies and resulted in congenital thrombocytopenia and lymphocytopenia in the last two offspring. The youngest baby died aged 16 days of severe combined immunodeficiency (SCID) with maternal graft-versus-host disease. The other affected child, however, recovered fully from thrombocytopenia and lymphocytopenia after exchange transfusion for presumed sepsis. The clinical courses indicated that an isoimmune process had caused both the thrombocytopenia and the lymphocytopenia. In accord with this conclusion, maternal titres of IgG antibodies against paternal platelets fell continuously in serial blood samples taken after the last pregnancy. Cytotoxicity studies of the maternal serum towards lymphocytes from the other siblings and from unrelated donors showed that the paternal antigen involved was a non-HLA determinant. It is postulated that isoimmune lymphocytopenia with subsequent immunological suppression is a potential mechanism for SCID and intrauterine engraftment of maternal lymphocytes.

Three patients from two families with complete hereditary deficiency of the fourth component of complement (C4) and systemic lupus erythematosus are described. The syndrome presented by these patients is characterized by early onset in life; exquisite sensitivity to sunlight and to cold exposure, the latter resulting Raynaud's phenomenon; and skin lesions involving not only exposed areas of the body but also palms and soles and presenting as butterfly rashes, maculopapular eruptions, and lesions similar to those of chronic discoid lupus erythematosus, with marked scaling, atrophy, and scarring. Lupus erythematosus (LE) cell tests were negative and antinuclear antibody (ANA) titers low or negative. The male patient of our series died at the age of 31/2 years from septicemia, whereas the two girls, aged 18 and 11 years, respectively, were alive at the time of writing. The C4-deficient gene is associated with HLA-Aw32, Bw38, and Bf S in one family and with HLA-A30, B18, DR7, and Bf S1 in the other family; the latter is the second family in which this HLA haplotype has been found to be associated with hereditary C4 deficiency.

Eleven adults have been transplanted for various reasons between July 1979 and July 1982: 2 with aplastic anemia (AA), 1 with paroxysmal nocturnal hemoglobinuria (PNH), 8 with acute leukemia (AL). Four patients suffered from acute lymphocytic leukemia (ALL) and four from acute non-lymphocytic leukemia (ANLL). Two of them were transplanted in relapse, 1 in a partial remission, and 5 in complete remission. All patients were in their late stage of disease. The PNH-patient had an identical twin, 8 patients had an HLA- and MLC compatible sib, 1 an unrelated donor, and 1 was transplanted from his father. Four patients are alive, 2 more than 3 years: 1 with AA and 1 with ALL who was transplanted in relapse. Six patients died of infectious complications (4 of interstitial pneumonia, 1 of a candida sepsis, 1 of acute toxoplasmosis). Patients living more than 3 weeks had a take. Acute graft-versus-host (GvH) disease did not present a major problem. All patients received methotrexate for GvH-prophylaxis, in three instances the marrow was additionally pre-incubated with anti-T-cell globulin.

During the 4-year period from June 1977 to May 1981, a total of 108 patients with polycystic kidney disease and 2440 nonpolycystic patients received cadaver renal allografts in the Southeastern Organ Procurement Foundation (SEOPF) Prospective Study. There were no significant differences between the groups with and without polycystic disease in terms of recipient blood group, history of splenectomy, or preformed antibody status. As a group, transplanted polycystic patients underwent native nephrectomy more often, had a better HLA match, received less antilymphocyte serum (ALS), and were slightly older than nonpolycystic patients. Although proportionately fewer polycystic patients received pretransplant transfusions than nonpolycystic patients (P = .002), transfusion was associated with a significant increase in graft survival in the polycystic group (P less than .05), as well as in the nonpolycystic group (P less than .0001). Gene frequency analysis showed no HLA-A, or -B antigen linkage with polycystic disease. No significant differences existed between the polycystic and nonpolycystic groups in terms of overall graft and patient survival. However, transplanted polycystic patients died more frequently from bacterial sepsis (P less than .05), especially from gram-positive organisms (P = .01). Pretransplant bilateral nephrectomy did not affect the incidence of sepsis. However, following graft failure, patients with bilateral native nephrectomy had a greater incidence of severe anemia (50% versus 39%) and death (58% versus 25%; P less than .05) than those with unilateral nephrectomy or no nephrectomy. Treatment with ALS did not significantly improve graft survival in those with polycystic disease. A strong positive correlation was found between patient death and treatment with ALS only in the polycystic group (P less than .01). These findings indicate that the use of pretransplant bilateral native nephrectomy and posttransplant ALS should be judicious in the polycystic patient because they may be associated with increased morbidity and mortality.

One hundred sixty-five high-risk patients who were either 50 years of age or older or had diabetes mellitus, or both underwent primary renal transplantation. One hundred eight had splenectomy and 57 did not. Graft and patient survival were analyzed in regard to whether splenectomy had been performed at all and whether it had been performed 30 days or more before transplantation, less than 30 days before, or at the time of transplantation. Also, the influence of age, diabetes, blood transfusions, blood type, donor type, HLA mismatch, pretransplantation dialysis, and percentage of performed antibodies were analyzed, as were complications and causes of death. Differences in patient survival were not significant in any one of these categories, although survival in the splenectomized group was generally better. The incidence of infection and sepsis was comparable in both groups and was responsible for death in 34 percent of the patients who underwent splenectomy compared with 22 percent of those who did not (no significant difference). Splenectomy improved cadaver donor renal allograft survival (p = 0.001) in the diabetic patients (p = 0.015) and in those 50 years of age or older (p = 0.026) but it did not improve survival in those who received living related donor kidneys. No significant differences were detectable in regard to the timing of splenectomy. The effect of splenectomy was significant in the patients who had not received transfusions (p = 0.003). It also improved survival in the transfused patients. Splenectomy in high-risk diabetic patients and patients 50 years of age or older does not seem to be associated with increased mortality.

Bone marrow transplants were carried out in 18 patients with chronic myelogenous leukemia (CML) in the chronic phase (CP). 12 (67%) are still alive, 11 without evidence of leukemia after a mean observation period of 24 (3-44) months, 1 relapsed and 6 died. The most frequent cause of death was GvHD and interstitial pneumonia (5). 1 patient died of septicemia. 2 grafts were performed in patients with CML in the accelerated phase (AP); both died, one from leukemic relapse and one from GvHD. The authors also participated in an international study in which 117 patients were evaluated. In CP there was a survival plateau at 63%, in AP at 36% and in blastic crisis at 12%. In CP mortality was primarily age-dependent and relapses occurred in only 7%. It is concluded that bone marrow transplantation (BMT) is a highly successful treatment for CML, with the CP the optimum moment for grafting. Longlasting cytogenetic and clinical remissions with potential for cure are possible in a high percentage of patients. The incidence of transplant-related mortality is acceptable. The incidence of leukemic relapse is low in CP. Patients under age 40 with HLA-identical siblings should be transplanted in CP. At present BMT is the only treatment with curative potential for CML.
