摘要:
The influence of total-body irradiation (TBI) and autologous or allogeneic bone marrow transplantation on serum immunoglobulin subclasses was determined in a dog model. Only IgG1, levels decreased after low-dose (± 4.5 Gy) TBI, but levels of all immunoglobulin classes fell after high-dose TBI (8.5 Gyx1 or 2x6.0 Gy). After autologous bone marrow transplantation IgM levels were the first and IgE levels were the last to return to normal. After successful allogeneic bone marrow transplantation prolonged low IgM and IgE levels were found but IgA levels increased rapidly to over 150% of pretreatment values. A comparison of dogs with or without clinical signs or graft-versus-host disease (GVHD), revealed no differences in IgM levels. Dogs with GVHD had higher IgA but lower IgE levels. Dogs that rejected their allogeneic bone marrow cells showed significant early rises in IgE and IgA levels in comparison with dogs with GVHD. These results differ from the observations made on Ig levels inhuman bone marrow transplant patients. No significant differences in phytohemagglutinin stimulation tests were found between dogs with or without GVHD or dogs receiving an autologous transplant for the first four months after TBI and transplantation. An early primary or secondary involvement of humoral immunity in GVHD and graft rejection in dogs is postulated.

摘要:
Patients undergoing orthotopic hepatic transplantation were studied with routinely available liver function studies and serial hepatic biopsies. Rejection was diagnosed only if confirmed histologically. Cyclosporine and a rapidly decreasing dose of corticosteroids were used for immunosuppression. Hepatic dysfunction suggesting rejection was seen in 22 instances, but acute rejection was diagnosed histologically in only 6 patients. The liver function studies used in these patients did not accurately distinguish rejection from other causes of hepatic dysfunction. We conclude that liver biopsy as performed in these patients is an accurate and safe means of assessing the adequacy of immunosuppression and minimizing the use of high dose corticosteroids.

摘要:
Four pediatric patients with diseases potentially curable by bone marrow transplantation (BMT)3—i.e., common variable immune deficiency, Wiskott-Aldrich Syndrome (WAS), mucopolysaccharidosis type VI, and mucopolysaccharidosis type I received a conditioning regimen consisting of busulfan and cyclophosphamide prior to BMT from HLA-identical, mixed leukocyte culture (MLC)-unreactive siblings. Only one of the four patients achieved full engraftment. Of the remaining three patients, one experienced failure of engraftment, and two had persistent mixed chimerism. Although no serious complications were directly related to the preparative therapy, the doses of busulfan and cyclophosphamide previously described to be adequate for conditioning children with WAS were completely effective in only one of three pediatric patients in this series. Despite a higher dose of busulfan (16 mg/kg), mixed chimerism was observed in a subsequent patient. Of 13 evaluable patients in the literature in whom busulfan and cyclophosphamide had been used as preconditioning regimens for a variety of nonmalignant conditions, eight demonstrated lack of complete and sustained engraftment. On the other hand, clinical improvement has accompanied partial engraftment in some cases. We conclude that additional immunosuppressive and/or myeloablative conditioning is necessary if complete engraftment is attempted in histocompatible allogeneic BMT for many of the nonmalignant disorders.

摘要:
Two hundred fifty-five patients received chemoradiotherapy and a marrow graft for treatment of malignancy. Fifty-three developed venocclusive disease (VOD) of the liver. The clinical presentation was characterized by jaundice, fluid retention, ascites, upper abdominal pain, and encephalopathy. Insidious weight gain was the first sign of VOD, occurring a mean of 6.2±5.2 days after transplantation, followed shortly by jaundice. Twenty-four patients (45%) had a serious, progressive liver disease, but the others recovered a mean of 21.6 days after the onset of jaundice. Analysis of pretransplant factors did not disclose a significant association with serious VOD. Patients with serious VOD had significantly higher maximal values for bilirubin and SGOT, gained more weight, and were more likely to have encephalopathy. Supportive treatment did not appear to influence the outcome.

摘要:
HLA-DR matching has been shown in a retrospective study of 72 renal transplant patients to significantly enhance graft survival at 12 months. HLA-A and -B antigen matching also increased the graft survival rate significantly. Analysis of combined HLA-A, -B and -DR matching suggested an improvement in graft survival rate with better matching, but this did not attain statistical significance. It is now our policy to use HLA-DR matching prospectively and to ensure that all recipients receive a kidney with a maximum of 1 HLA-DR incompatibility and a minimum of 2 HLA-A and -B antigens shared.

摘要:
To establish the impact of transplantation on the course of chronic hepatitis B liver disease we performed a prospective study of the clinical and pathological sequelae of hepatitis B disease in all 22 patients who had renal allografts that functioned for more than 1 year and who were hepatitis B surface antigen (HB Ag)-positive following transplantation. No patient converted to HB Ag-negative. During a mean follow-up of 83 months serial liver biopsies were performed in 20 patients and 1 liver biopsy was available in the remaining 2 patients. Eleven patients died of liver disease, 5 of whom died of hepatic failure, 3 with hepatoma, 2 of gastrointestinal hemorrhage, and 1 of ascites with pleuroperitoneal fistula. Aggressive liver disease was observed in the vast majority of patients: 12 ultimately developed cirrhosis, (mean follow-up 81 months), 6 chronic active hepatitis (mean follow-up 93 months), 3 chronic persistent hepatitis (mean follow-up 93 months), 3 chronic persistent hepatitis (mean follow-up 89 months), and in 1 patient the presence of HB virus in hepatocytes was the sole morphologic alteration (follow-up 42 months). There was a marked tendency to progression in that 82% of patients with virus only, reactive hepatitis, or chronic persistent hepatitis on initial biopsy subsequently developed chronic active hepatitis of cirrhosis.For comparison, 10 HB Ag-positive patients whose renal failure had been treated by hemodialysis were also studied over a comparable period. Four patients converted to the negative state. Biochemical evidence of persistent liver dysfunction occurred in only 1 patient and no patient has died from complications of liver disease.We conclude that in the immunosuppressed renal transplant patient HB infection often results in the development of cirrhosis, leading to death from hepatoma and hepatic failure. This course is worse than that in dialysis patients. Renal transplantation of HB Ag-positive patients with end-stage renal failure may be inadvisable.

摘要:
Our experience over the last 4 years with HLA-identical, donor-specific transfusion (DST), and Imuran (IM)+DST living-donor transplants in 206 patients is presented. Transplants from 8 completely incompatible sibling donors, 4 distantly related donors, and 7 unrelated donors are included. Except for a slightly higher average serum creatinine, and a markedly reduced rate of donor-specific sensitization in the IM+DST group when compared with the DST group (14% vs. 31%,p< .005), the results of transplantation using these 3 protocols have been equivalent. Actuarial one-year survival was 97% for patients and 93% for grafts for the combined group of 206 patients. Of the 44 patients who entered the DST or IM+DST protocols but were not transplanted, 31 patients (70%) have subsequently been transplanted, and all 5 recipients of living-donor kidneys and 20 of 26 recipients of cadaveric kidneys (77%) have functioning grafts.Because it optimizes the availability of transplantable living-donor kidneys, gives results equivalent to those obtained with HLA-identical donors and the DST protocol, and is not associated with clinically apparent adverse effects, we now use the IM+DST protocol for all living-donor transplants except those between HLA-identical donor-recipient pairs.

摘要:
We prospectively studied 41 marrow transplant patients to evaluate the possible association of hypomagnesemia with cyclosporine immunosuppressive therapy. During the 3 months posttransplant the mean nadir serum magnesium level was 1.06±0.16 mEq/L in 24 patients treated with cyclosporine and 1.33±0.13 in 14 patients treated with methotrexate (P<0.0001). Eleven of 24 patients receiving cyclosporine versus 1 of 14 patients receiving methotrexate had magnesium levelsP<0.02). Agents known to be associated with hypomagnesemia, aminoglycosides and amphotericin B, were given in both lesser quantity and frequency to cyclosporine-treated patients than to methotrexate-treated patients. Hypomagnesemic patients treated with cyclosporine had inappropriately elevated urine magnesium excretion. Renal magnesium wasting may be added to the spectrum of nephrotoxicity resulting from cyclosporine. Several adverse reactions previously attributed to cyclosporine may be secondary to magnesium deficiency.

摘要:
During treatment of heart-grafted rats with cyclosporine, an unusual large lymphocyte appears in the blood. These cells constitute up to 40% of the peripheral blood leukocyte population and carry both the T helper/DTH and T cytotoxic/suppressor differentiation antigens. They require both the allograft and CsA for their generation and are not recently thymus-derived. They gradually disappear after stopping CsA treatment, although the treated rats remain tolerant of the graft.
