The role of orthotopic liver transplantation in the treatment of ornithine transcarbamylase deficiency.

The purpose of this study was to combine our clinical experience with a review of the literature to determine the value of orthotopic liver transplantation in the treatment of both boys and girls with ornithine transcarbamylase deficiency. Three boys younger than 1 year of age with symptomatic ornithine transcarbamylase deficiency (median age, 116 days; range, 40 to 223 days) underwent orthotopic liver transplantation. The patients' growth, developmental progress, ammonia levels, and amino acid levels were analyzed pre- and post-liver transplantation. The clinical courses of the respective patients and the treatment modalities used were compared with published reports from 1978 through 1997. The median follow-up period in these 3 patients was 3.2 years (range, 9 months to 5.2 years). Orthotopic liver transplantation restored normal urea production and stabilized ammonia levels within 24 hours of surgery (median serum ammonia level 24 hours post-liver replacement, 43 micromol/L; range, 30 to 66 micromol/L). After liver replacement, arginine synthesis was normalized; however, plasma citrulline levels remained less than normal in all patients. Linear growth was evaluated in all 3 patients at the time of the most recent follow-up; median z scores for patient height and weight were -2.16 and -1.16, respectively. Standardized intelligence tests showed that 2 of the 3 patients continue to perform at age-appropriate levels. The third child was developmentally delayed pretransplantation at 4 months of age on presentation and continues to perform in a below-average fashion. Orthotopic liver transplantation results in the restoration of normal urea production and serum ammonia levels in the boy suffering from symptomatic ornithine transcarbamylase deficiency. Serum arginine, but not citrulline, levels are normalized, probably because of the persistent intestinal mucosa defect. Patient growth is similar to that in infants undergoing liver transplantation for other causes. When liver transplantation is performed before cognitive impairment occurs, intellectual development is normal, because the risk of additional episodes of hyperammonemia is elevated.

Adult liver transplantation for metabolic liver disease.

Liver replacement provides an effective method of replacing a failing liver, and corrects the underlying defect in many metabolic conditions. Results of liver transplantation for metabolic diseases have been encouraging, with the exception of hereditary hemochromatosis, in which infectious and for which cardiac complications appear to increase posttransplant mortality. An improved understanding of the underlying genetic and molecular defect will lead to advances in medical therapy and perhaps will decrease the need for liver replacement. The prospects of gene therapy are being pursued for many metabolic disorders, however until this research leads to direct clinical application, liver transplantation remains the only effective option for many patients with metabolic liver disease.

Reduction of hepatic ischemia/reperfusion injury by a soluble P-selectin glycoprotein ligand-1.

OBJECTIVE: The authors' goal was to determine the effects of specific binding and blockade of P- and E-selectins by a soluble P-selectin glycoprotein ligand-1 (PSGL-1) in rat models of hepatic in vivo warm ischemia and ex vivo cold ischemia. The authors also sought to determine the effect of selectin blockade on isograft survival in a syngeneic rat orthotopic liver transplant model. SUMMARY BACKGROUND DATA: Ischemia/reperfusion (I/R) injury is a major factor in poor graft function after liver transplantation, which may profoundly influence early graft function and late changes. It is hypothesized that I/R injury leads to the upregulation of P-selectin, which is then rapidly translocated to endothelial cell surfaces within 5 minutes of reperfusion of the liver, initiating steps leading to tethering of polymorphonuclear neutrophil leukocytes to the vascular intima. Local production by leukocytes of interleukin-1, tumor necrosis factor-alpha, or both induces P-selectin expression on the endothelium and continues the cascade of events, which increases cell adherence and infiltration of the organ. METHODS: To examine directly the effects of selectins in a warm hepatic I/R injury model, 100 microg of PSGL-1 or saline was given through the portal vein at the time of total hepatic inflow occlusion. The effects of PSGL-1 in cold ischemia were assessed using an isolated perfused rat liver after 6 hours of 4 degrees C storage in University of Wisconsin (UW) solution, with or without the instillation of PSGL-1 before the storage. To evaluate the effect of selectin blockade on liver transplant survival, syngeneic orthotopic liver transplants were performed between inbred male Sprague-Dawley rats after 24 hours of cold ischemic storage in UW solution. A separate group of animals received two doses of 100 microg of PSGL-1 through the portal vein before storage and before reperfusion of the transplanted liver. Recipient survival was assessed at 7 days, and the Kaplan-Meier product limit estimate method was used for univariate calculations of time-dependent recipient survival events. RESULTS: In an in vivo warm rat liver ischemia model, perfusion with PSGL-1 afforded considerable protection from I/R injury, as demonstrated by decreased transaminase release, reduced histologic hepatocyte damage, and suppressed neutrophil infiltration, versus controls (p < 0.05). When cold stored livers were reperfused, PSGL-1 reduced the degree of hepatocyte transaminase release, reduced neutrophil infiltration, and decreased histologic hepatocyte damage (p < 0.05 vs. UW-only controls). On reperfusion, livers treated with PSGL-1 demonstrated increased portal vein blood flow and bile production (p < 0.05 vs. UW-only controls). In addition, 90% of the rats receiving liver isografts stored in UW solution supplemented with PSGL-1 survived 7 days versus 50% of those whose transplanted syngeneic livers had been stored in UW alone (p < 0.05). CONCLUSIONS: Selectins play an important role in I/R injury of the liver. Early modulation of the interaction between P-selectin and its ligand decreases hepatocyte injury, neutrophil adhesion, and subsequent migration in both warm and cold rat liver ischemia models. In addition, the use of PSGL-1 before ischemic storage and before transplantation prevents hepatic injury, as documented by a significant increase in liver isograft survival. These findings have important clinical ramifications: early inhibition of alloantigen-independent mechanisms during the I/R damage may influence both short- and long-term survival of liver allografts.

Long-term results of pediatric liver transplantation: an analysis of 569 transplants.

OBJECTIVE: To analyze a single center's 13-year experience with 569 pediatric orthotopic liver transplants for end-stage liver disease. SUMMARY BACKGROUND DATA: Despite advances in medical therapy, liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease. Innovative surgical techniques and improved immunosuppression have broadened the application of liver replacement for affected children. However, liver transplantation in the child remains challenging because of the scarcity of donor organs, complex surgical technical demands, and the necessity to prevent long-term complications. METHODS: The medical records of 440 consecutive patients younger than 18 years of age undergoing orthotopic liver transplantation for end-stage liver disease from March 20, 1984, to November 15, 1997, were reviewed. Results were analyzed using Cox multivariate regression analysis to determine the statistical strength of independent associations between pretransplant covariates and patient and graft survival. Actuarial patient and graft survival rates were determined at 1, 3, 5, and 10 years. The type and incidence of posttransplant complications were determined, as was the quality of long-term allograft function. The median follow-up period was 4.1 years. RESULTS: Biliary atresia was the most common cause (50.4%) of endstage liver disease in this patient population. The median recipient age was 2.4 years; 239 patients (54%) were younger than 3 years of age and 1 11 patients (25%) were younger than 1 year of age. There were 471 whole organs, 29 were ex vivo reduced size, 33 were living-related donor, and 36 were in situ split-liver allografts. Three hundred forty-three (78%) patients underwent a single allograft, whereas 97 patients required retransplantation; hepatic artery thrombosis was the most common indication for retransplantation (55 patients). The 1-, 3-, 5-, and 10-year actuarial patient survival rates were 82%, 80%, 78%, and 76%, respectively; allograft survival rates were 68%, 63%, 60%, and 54%. Long-term liver function remains excellent: current median follow-up values for total bilirubin and aspartate aminotransferase were 0.5 mg/dl and 54 IU/L, respectively. Cox multivariate regression analysis demonstrated that pretransplant patient age, the era of transplantation, and the number of allografts performed significantly and independently predicted patient survival rates, whereas allograft type and pretransplant diagnosis did not. CONCLUSIONS: Liver transplantation in the pediatric patient is a durable procedure that provides excellent long-term survival. Although there have been overall improvements in patient outcome with increased experience, the effect is most pronounced for patients younger than 1 year of age. Retransplantation, although effective in a meaningful number of patients, continues to carry a progressive decrement in survival with the number of allografts performed. Use of living-related and in situ split-liver allografts has dramatically reduced waiting times for small children and has improved patient survival.

In situ splitting of the cadaveric liver for transplantation.

BACKGROUND: The shortage of cadaveric donor livers is the rate-limiting step in clinical liver transplantation. Split liver transplantation provides a means to expand the cadaveric donor pool. However, this concept has not reached its full potential because of inferior patient and graft survival and high complication rates when traditional ex vivo split techniques are used. Therefore we sought to evaluate the safety, applicability, and effectiveness of a new technique for split liver transplantation. METHODS: This study consists of 15 in situ split liver procurements, which resulted in 28 liver transplants. In situ splitting of selected livers from hemodynamically stable cadaveric donors was performed at the donor hospital without any additional work-up or equipment being needed. In situ liver splitting is accomplished in a manner identical to the living-donor procurement. This technique for liver splitting results in a left lateral segment graft (segments 2 and 3) and a right trisegmental graft (segments 1 and 4-8). This procedure required the use of the donor hospital operating room for an additional 1.5-2.5 hr and did not interfere with the procurement of 30 kidneys, 12 hearts, 7 lungs, and 9 pancreata from these same donors. RESULTS: The 6-month and 1-year actuarial patient survival rates were 92% and 92%, respectively, while the 6-month and 1-year actuarial graft survival rates were 86% and 86%, respectively. The 6-month and 1-year actuarial patient survival rate of patients who received a left lateral segment graft was 100% and 100%, respectively, while those who received a right trisegmental graft had 6-month and 1-year rates of 86% and 86%, respectively. The actuarial death-censored graft survival rates at 6 months and 1 year were 80% and 80%, respectively, for the left lateral segment grafts, and 93% and 93%, respectively, for the right trisegmental grafts. Alograft and patient survival was independent of United Network for Organ Sharing status at the time of liver transplantation. No patient developed a biliary stricture, required re-exploration for intra-abdominal hemorrhage, or suffered from portal vein, hepatic vein, or hepatic artery thrombosis CONCLUSIONS: In situ split liver transplantation can be accomplished without complications and provides results that are superior to those obtained previously with ex vivo methods. It abolishes ex vivo benching and prolonged ischemia times and provides two optimal grafts with hemostasis accomplished. This technique decreases pediatric waiting time and allows adult recipients to receive right-sided grafts safely. In situ splitting is the method of choice for expanding the cadaveric liver donor pool.

Lower extremity paralysis after use of the supraceliac aorta for hepatic arterial reconstruction of the transplanted liver.

Use of the supraceliac aorta for hepatic arterial reconstruction of the transplanted liver in the setting of inadequate recipient celiac and hepatic arterial inflow has been advocated and has resulted in a decreased hepatic artery thrombosis rate in both the adult and pediatric populations. Over the past 6 years, we have utilized the supraceliac aorta in more than 200 patients without complication. However, in this communication, we report a major neurologic complication that resulted in anterior spinal artery syndrome.

Aplastic anemia complicating orthotopic liver transplantation.

The clinical characteristics and outcome of posttransplantation aplastic anemia (AA) were determined in 12 of 1,736 patients (0.007%) undergoing orthotopic liver transplantation (OLT) that were afflicted with AA. None of the affected patients had a history of hematologic disease. Median patient age was 53 years (range, 2-61 years); 10 of the affected patients were men, and 2 were women. The etiologies of AA included non-A, non-B, non-C fulminant hepatic failure (FHF) (3 patients), graft-versus-host disease (4 patients), Parvovirus-induced (1 patient), and idiopathic (4 patients). The median duration between OLT and the onset of AA was 12 days (range, 11-14 days) in the 3 patients undergoing OLT for FHF; in contrast, AA developed in the other 9 patients at 37 days (range, 27-51 days) after OLT. Eleven patients were treated with reduction of their cyclosporine or tacrolimus dosage, granulocyte colony-stimulating factor, anti-thymocyte globulin, and Solumedrol. Two of the 3 patients developing AA following OLT for FHF achieved hematologic recovery 21 and 92 days after diagnosis. In contrast, all 9 non-FHF patients developing AA after OLT died, 5 due to infectious complications and 4 following intracranial bleeding. AA is an unusual complication of OLT. In the setting of FHF, it affects young males in the early posttransplantation period, and, when infectious complications can be avoided, remission and stable allograft function can be anticipated. However, in the non-FHF patient, AA occurs in older individuals later in the posttransplantation period and has a uniformly poor outcome.

The impact of microsurgical hepatic arterial reconstruction on the outcome of liver transplantation for congenital biliary atresia.

BACKGROUND: Hepatic artery thrombosis (HAT) after liver transplantation for biliary atresia (BA) is a serious complication that most often leads to retransplantation (re-OLT). The purpose of the present study was: (1) to identify risk factors associated with HAT and (2) to analyze the impact of recently introduced microsurgical hepatic arterial reconstruction (MHR) on the incidence of HAT, subsequent need for re-OLT, and patient survival. METHODS: A retrospective review of 194 patients transplanted for BA was performed. One hundred and sixty-six patients (group 1) underwent conventional arterial reconstruction and 28 (group 2) had MHR. RESULTS: Actuarial survival for patients with HAT was significantly worse than for patients without HAT at 1, 2, and 5 years (71%, 61%, and 57% versus 85%, 85%, and 85%, P = 0.0007). Stepwise logistic regression analysis revealed that the risk of HAT correlated best with the type of arterial reconstruction (P = 0.007) followed by pretransplant bilirubin concentration (P = 0.04) and the number of acute rejection episodes (P = 0.03). In group 1, 32 patients developed HAT (19%), and of these, 18 underwent re-OLT for HAT. No patient in group 2 developed HAT (P = 0.006 versus group 1). One-year actuarial patient survival was 81% in group 1 and 100% in group 2 (P = 0.02). CONCLUSIONS: In OLT for BA, (1) the predominant risk factor for HAT is the technique of arterial reconstruction, and (2) MHR markedly reduces the incidence of HAT and the need for re-OLT while improving patient survival.

Orthotopic liver transplantation for primary sclerosing cholangitis. A 12-year single center experience.

OBJECTIVE: The purpose of this study was to analyze a single center's 12-year experience with 127 orthotopic liver transplantations (OLT) for primary sclerosing cholangitis (PSC). SUMMARY BACKGROUND DATA: Primary sclerosing cholangitis is a chronic cholestatic liver disease of unknown origin that occurs most commonly in young men and is associated frequently (70-80%) with inflammatory bowel disease (IBD). Patients with PSC also are at risk for the development of cholangiocarcinoma (CCA) and those with IBD for colon carcinoma. Although the course of PSC is variable, it frequently is progressive, leading to cirrhosis and requirement for OLT. METHODS: The medical records of 127 consecutive patients undergoing OLT for PSC from July 1, 1984, to May 30, 1996, were reviewed. Actuarial patient and graft survival was determined at 1,2, and 5 years. The incidence and outcome of patients with CCA, recurrent sclerosing cholangitis, and post-transplant colon carcinoma was determined. Results were analyzed by way of stepwise Cox regression to determine the statistical strength of independent associations between pretransplant covariates and patient survival. The median follow-up period was 3.01 years. Incidental cholangiocarcinoma (ICCA) was defined as a tumor < 1 cm in size that was discovered at the time of pathologic sectioning of the explanted liver. RESULTS: Ninety-two patients (72%) had associated IBD. Seventy-nine (62%) had undergone previous biliary tract surgery. One hundred seven patients (84%) received a single graft, whereas 20 patients (16%) required 22 retransplants. Patients received either cyclosporine- (n = 76) or tacrolimus- (n = 51) based immunosuppression. The 1-, 2-, and 5-year actuarial patient survivals were 90%, 86%, and 85%, respectively, whereas graft survival was 82%, 77%, and 72%, respectively. The presence of previous biliary surgery had no effect on patient survival. Ten patients (8%) had ICCA and their survival was not significantly different from patients without ICCA (100%, 83%, and 83% at 1, 2, and 5 years, respectively). Four patients were known to have CCA at the time of OLT, all recurred within 6 months, and had a significantly worse outcome (p < 0.0001). Recurrent sclerosing cholangitis developed in 11 patients (8.6%). The patient and graft survival in this group was not different from those in whom recurrence did not develop (patient; 100%, 90%, and 90%; graft: 80%, 70%, and 52%). Thirty patients (23%) underwent colectomy after liver transplantation for dysplasia-carcinoma or symptomatic colitis. Of the nine covariates entered into the Cox multivariate regression analysis, only common bile duct frozen section biopsy specimen showing CCA was predictive of a survival disadvantage. CONCLUSIONS: Liver transplantation provides excellent patient and graft survival rates for patients affected with PSC independent of pretransplant biliary tract surgery. Incidental cholangiocarcinoma does not affect patient survival significantly. However, known CCA or common duct frozen section biopsy specimen or both showing CCA are associated with poor recipient survival, and OLT should be proscribed in these cases. Recurrent PSC occurs in approximately 9% of cases but does not affect patient survival. Post-transplant colectomy does not affect patient survival adversely.

A prospective study on the reliability and cost effectiveness of preoperative ultrasound screening of the "marginal" liver donor.

With the growing shortage of available liver donors, many donors with risk factors that would have traditionally precluded liver procurement are now being considered. In this prospective study, we evaluated 50 "marginal" liver donors with pre-procurement abdominal ultrasounds and correlated results with findings at procurement and with subsequent allograft function. The results show that the ultrasounds have a specificity of 96% and a sensitivity of 68% in predicting abnormalities in donor livers that precluded transplantation. In addition, using ultrasound to screen marginal donors would result in significant savings in manpower and hospital resource utilization without "missing" any normal liver organs. Our results also show that, when properly selected, livers from donors with one or more high-risk factors function well with acceptable primary nonfunction rates.

Successful transfer of immune unresponsiveness to concordant rat islet xenografts.

Indefinite survival of concordant xenogeneic Wistar Furth (WF) rat islet survival was obtained by intrahepatic transplants of cultured WF islets and a single injection of antilymphocyte sera in C57BL/6 mice. Adoptive transfer of splenocytes from mice with established WF islet xenografts produced a marked prolongation of survival of WF islets transplanted under the kidney capsule of diabetic irradiated (600 rads), naive C57BL/6 recipients (mean survival time = 48.9 +/- 17.1 days), and three of the recipients were still normoglycemic at 100 days after transplantation. Adoptive transfer of an equal mixture (3 x 10(7) cells each) of these splenocytes with normal splenocytes also prolonged survival of the kidney capsule islet xenografts (mean survival time = 26.5 +/- 7.8 days vs. 15.2 +/- 5.3 days for controls). In vitro studies on lymphocyte proliferation demonstrated a low rate of proliferation of splenocytes from established islet xenografts in the presence of irradiated WF splenocytes (stimulation index = 1.6 vs. 16.2 for naive C57Bl/6 mice), and mixing the cells with control splenocytes also decreased the proliferation of splenocytes as compared with controls (stimulation index = 5.4 vs. 16.2 in controls). The inhibitory effect was not species specific, since splenocytes from mice with established islet xenografts also produced a 42% inhibition of proliferation in the presence of irradiated Lewis splenocytes. These findings demonstrate that concordant, islet xenograft, immune unresponsiveness can be adoptively transferred by splencotyes from mice with established islet xenografts.

Orthotopic liver transplantation for congenital biliary atresia. An 11-year, single-center experience.

OBJECTIVE: The authors analyze a single center's 11-year experience with 190 orthotopic liver transplants for congenital biliary atresia. SUMMARY BACKGROUND DATA: Hepatic portoenterostomy generally is the initial treatment for children with congenital biliary atresia. Despite multiple modifications of the hepatic portoenterostomy, two thirds of treated patients still develop recurrent cholestasis, portal hypertension, cholangitis, and cirrhosis. Therefore, the only hope of long-term survival in the majority of children with congenital biliary atresia is definitive correction with orthotopic liver transplantation. METHODS: The medical records of 190 consecutive patients undergoing orthotopic liver transplantation for congenital biliary atresia from July 1, 1984 to February 29, 1996 were reviewed. Results were analyzed via Cox multivariate regression analysis to determine the statistical strength of independent associations between pretransplant covariates and patient and graft survival. Actuarial patient and graft survival was determined at 1, 2, and 5 years. The type and incidence of post-transplant complications were determined, as was the quality of long-term graft function. The median follow-up period was 3.21 years. RESULTS: The liver grafts were comprised on 155 whole-organ, 24 reduced-size, and 11 living donor organs. Median pretransplant values for recipient age, weight, and total bilirubin were 1.4 years, 12.3 kg, and 13.8 mg/dL, respectively. One hundred sixty-four patients (86%) had undergone prior hepatic portoenterostomy. Eighty-seven patients (46%) were United Network for Organ Sharing (UNOS) status 1 or 2 at the time of liver transplantation. The majority (15/24, 62%) of reduced-size graft recipients were UNOS status I at the time of transplantation. One hundred fifty-nine patients (84%) received a single graft, whereas 31 patients required 37 retransplants. The 1, 2, and 5 year actuarial patient survival rates were 83%, 80% and 78% respectively, whereas graft survival rates were 81%, 77%, and 76%, respectively. Cox multivariate regression analysis demonstrated that pretransplant total bilirubin, UNOS status, and graft type significantly predicted patient survival, whereas recipient age, weight, and previous hepatic portoenterostomy did not. Current median follow-up values for total bilirubin and aspartate aminotransferase levels in the 154 surviving patients were 0.5 mg/dL and 34 international units/L, respectively. CONCLUSION: Long-term patient survival after orthotopic liver transplantation for congenital biliary atresia is excellent and is independent of recipient age, weight, or previous hepatic portoenterostomy. Optimal results are obtained in this patient population when liver transplantation is performed before marked hyperbilirubinemia, and when possible, using a living-donor graft.

Induction of allogeneic islet survival by intrahepatic islet preimmunization and transient immunosuppression.

Induction of tolerance to fully major histocompatibility complex (MHC)-mismatched rat islet allografts implanted at two different islet transplant sites (liver and kidney capsule [KC]) was examined. Streptozotocin-induced diabetic Lewis (RT1(1)) rats remained hyperglycemic (> 200 mg/dl) after intrahepatic preimmunization by injection of 200 low-temperature cultured (24 degrees C for 7 days) Wistar-Furth (WF, RT1u) rat islets into the portal vein with one injection (1 ml) of rat antilymphocyte serum intraperitoneally. Three weeks later, 1,200 WF islets that had been cultured to remove passenger lymphoid cells were transplanted into the liver via the portal vein or under the KC. The intrahepatic transplants survived 60.2 +/- 11.9 days, and all six of the KC transplants maintained normoglycemia for > 100 days after the preimmunization regimen. In contrast, survival of fresh islet transplants was not significantly improved by this preimmunization protocol at either transplantation site. This study demonstrates that indefinite islet allograft survival can be achieved across a full MHC mismatch by intrahepatic preimmunization with a small number of cultured donor islets and a brief period of immunosuppression followed by transplantation of low-temperature cultured donor islets.

Successful treatment of intraoperative malignant hyperthermia during renal transplantation.

Malignant hyperthermia is a complication of general anesthesia that is especially problematic if it occurs during renal transplantation because myoglobinemia, shock, and ischemia play a role in injuring the transplanted kidney. In this report, we describe a case of malignant hyperthermia, its clinical course, and the measures taken to successfully treat it and preserve the function of a kidney allograft.

Donor-specific transfusions have long-term beneficial effects for human renal allografts.

From April, 1980 to November, 1988, 163 one or two haplotype-mismatch living related (LR) or living unrelated (LUR) potential renal transplant recipients received three 200 ml aliquots of donor specific transfusion (DST) at biweekly intervals with concomitant azathioprine (2 mg/kg/day). Following transplantation, only prednisone and azathioprine were given for immunosuppression. The results for the DST group are compared with those for HLA identical living recipients (57 patients) transplanted during this same interval (1980-1988). Comparison is also made with a group of one or two haplotype-mismatched living donor recipients (54 patients) not treated with DST but with triple drug therapy (prednisone, azathioprine, cyclosporine) and antithymocyte globulin (ATG) or OKT-3 induction. Permanent T cell crossmatch sensitization occurred in 11 of 163 patients (7%). Successful DST donor transplants were performed between 121 one HLA haplotype-mismatched, 14 two HLA haplotype-mismatched LR, and 7 two haplotype-mismatched LUR pairs. Actual one- and five-year graft survivals were 94%, 100%, 100%, and 72%, 85%, and 71%, respectively, for these three subgroups of DST treated patients. The graft survival for all DST pretreated recipients at one, five, and ten years was comparable to the HLA-identical group (94%, 79%, 64% vs. 91%, 80% and 77%). At a mean follow-up of 10 1/2 years, 54% (80 patients) of the entire group of 147 patients transplanted after DST have functioning transplants with a mean serum creatinine of 1.7 mg/dl. Fifteen percent of DST patients (21 patients) died with a functioning graft 2 to 132 months after transplantation, 26% (37 patients) rejected the DST graft after 1 to 128 months, and 6% (9 patients) were lost for nonimmunological reasons. No lymphoproliferative disease developed in the DST group and the incidence of cytomegalovirus sepsis was only 2% (3 patients). The long-term beneficial effects of DST on renal allograft survival and function and the lower incidence of the complications of nonspecific immunosuppression should encourage increased utilization of DST in renal transplantation.

Renal transplantation one week after conception.

A successful 38-week pregnancy is reported following renal transplantation approximately 1 week after conception. The patient was treated with quadruple sequential induction therapy, maintenance immunosuppression, and routine posttransplantation care, including ganciclovir treatment for a symptomatic cytomegalovirus infection during the pregnancy and 3 months after delivery. No decline in renal function was noted. The mother and child remain healthy at 18 months. This case demonstrates the ability of renal transplant patients to maintain renal function throughout pregnancy and the lack of deleterious effects upon the child during gestation and at up to 18 months after birth, despite significant immunosuppression, including antithymocyte globulin induction therapy, and infectious complications of the mother's renal transplantation.

Common variable immunodeficiency in a renal transplant patient with severe recurrent bacterial infection: a case report and review of the literature.

The second reported case of common variable immunodeficiency (acquired agammaglobulinemia) after renal transplantation is presented. Agammaglobulinemia presumably resulted from long-standing immunosuppression. This case and our review of the literature indicate that agammaglobulinemia is a rare event after transplantation but can be treated successfully with intravenous immunoglobulin. Additionally, hypogammaglobulinemia occurs frequently after transplantation and should be monitored and treated in appropriate clinical situations. The treatment of our patient with intravenous immunoglobulin also suggests that patients with common variable immunodeficiency can undergo renal transplantation.
