Cyclosporine sparing with mycophenolate mofetil, daclizumab and corticosteroids in renal allograft recipients: the CAESAR Study.

Although the calcineurin inhibitors (CNI) cyclosporine (CsA) and tacrolimus are highly effective immunosuppressants, they are associated with serious side effects. There is great interest in immunosuppressive regimens that permit reduction or elimination of CNIs, while maintaining adequate immunosuppression and acceptable acute rejection rates. Patients (n = 536) receiving their first renal allograft were randomized to one of three immunosuppressant regimens: daclizumab, mycophenolate mofetil (MMF), corticosteroids (CS) and low-dose CsA (target trough levels of 50-100 ng/mL), weaned from month 4 and withdrawn by month 6; daclizumab, MMF, CS and low-dose CsA; or MMF, CS and standard-dose CsA. Mean GFR 12 months after transplantation (primary end point) was not statistically different in the CsA withdrawal and low-dose CsA groups (both 50.9 mL/min/1.73 m(2)) vs. the standard-dose CsA group (48.6 mL/min/1.73 m(2)). At 12 months, the incidence of biopsy-proven acute rejection was significantly higher in the CsA withdrawal group (38%) vs. the low- or standard-dose CsA groups (25.4% and 27.5%, respectively; p < 0.05). In summary, a regimen of continuous low-dose CsA with MMF, CS and daclizumab induction is a clinically safe and effective immunosuppressive regimen in renal transplant recipients.

[Skin tumors in organ-transplant recipients].

Skin cancers are a significant medical problem for organ-transplant recipients. Squamous cell carcinoma and basal cell carcinoma are most common tumors. An increasing incidence of melanoma, Kaposi sarcoma, Merkel cell carcinoma, as well as uncommon skin malignancies, is also seen. Predisposing factors include cumulative sun exposure, cumulative immunosuppression, age, gender, skin type, virus detection and genetic alterations. Skin tumors grow rapidly and their number continues to increase in the years following transplantation. Large numbers of tumors, aggressive courses and appearance in young patients are other characteristics of these skin tumors. More general awareness of the need for preventive measures and regular dermatological examinations is desirable. In addition standardized registries are needed to assure the comparability of data, to better correlate immunosuppression with skin tumors and to plan therapeutic studies.

Conversion to enteric-coated mycophenolate sodium from various doses of mycophenolate mofetil: results of a prospective international multicenter trial in maintenance renal transplant patients receiving cyclosporine.

Conversion from mycophenolate mofetil (MMF, CellCept) to enteric-coated mycophenolate sodium (EC-MPS, myfortic) is safe and effective in renal transplant patients treated with the standard dose of 2 g MMF. In this 6-month, international, multicenter, open-label, single-arm trial, a large cohort of maintenance renal transplant patients receiving different doses of MMF were converted under normal clinical conditions to equimolar doses of EC-MPS. Mean calculated creatinine clearance remained stable from the time of study entry (59.6 +/- 19.7 mL/min) to the end of the study (58.3 +/- 19.8 mL/min). Adverse events were reported by 152 patients (67%), with gastrointestinal complications being observed in 45 patients (20%). Thirty-three patients (15%) experienced adverse events or infections with a suspected relation to EC-MPS, including one case of anemia and two cases of leukopenia. Eleven patients (4.9%) required a reduction in EC-MPS dose and seven patients (3.1%) permanently discontinued EC-MPS owing to adverse events. At month 6 after conversion, five patients (2.2%) experienced biopsy-proven acute rejection. There were no graft losses or deaths. These data support earlier findings that stable maintenance renal transplant patients receiving MMF with cyclosporine with or without corticosteroids can be converted to EC-MPS with no compromise in efficacy and tolerability, and no adverse effect on renal function.

MDR1 C3435T polymorphisms correlate with cyclosporine levels in de novo renal recipients.

BACKGROUND: Single nucleotide polymorphisms (SNPs) in the multidrug resistance (MDR1) gene correlate with the intestinal function of P-glycoprotein (PGP). PGP serves as a hydrophobic export pump that extrudes cyclosporine (CsA) across the luminal membrane thus preventing CsA absorption. These genetic variants may predict CsA exposure levels in the early posttransplantation period. METHODS: CsA absorption profiles were established in 75 renal transplant patients using total daily dose and body weight adjusted 4-hour area under the time-concentration curve, AUC(0-4)/mg dose/kg body weight, on posttransplant day 3. These patients were subsequently genotyped for C3435T and G2677T polymorphisms using real-time polymerase chain reaction. An analysis was conducted to assess the independent impact of C3435T and G2677T SNPs on CsA bioavailability. RESULTS: C3435T polymorphisms were found to be an independent predictor of CsA AUC(0-4)/mg dose/kg levels on postoperative day 3. An inverse correlation was found between the number of T alleles and AUC values such that every T allele was associated with an approximate 15% decrement in AUC(0-4)/mg dose/kg (P = .034). A similar nonsignificant trend was observed for G2677T polymorphisms. CONCLUSIONS: MDR1 SNPs are correlated with CsA exposure in the early post-transplant period. Polymorphisms, in conjunction with other criteria, may become a useful tool to optimize initial drug dosing in renal transplantation.

FTY720 versus MMF with cyclosporine in de novo renal transplantation: a 1-year, randomized controlled trial in Europe and Australasia.

FTY720 is a novel immunomodulator investigated in de novo renal transplantation and other therapeutic areas including multiple sclerosis. This 1-year multicenter, randomized, phase III study in 668 de novo renal transplant patients compared FTY720 2.5 mg plus full-dose cyclosporine (FDC) or FTY720 5.0 mg plus reduced-dose cyclosporine (RDC), with mycophenolate mofetil (MMF) plus FDC. The primary efficacy endpoint was the composite incidence of first treated biopsy-proven acute rejection (BPAR), graft loss, death or premature study discontinuation at month 12. Primary efficacy with FTY720 2.5 mg and MMF (32.4% and 30.2%; p = NS), plus mortality and BPAR incidence, were comparable. Patients receiving FTY720 5.0 mg plus RDC were discontinued from treatment due to increased risk of acute rejection (primary endpoint incidence 47.3%). FTY720 was associated with lower creatinine clearance (month 12: 53.1, 56.0 vs. 65.1 mL/min; p < 0.001) and more macular edema cases (2.2% and 1.3% vs. 0%), whereas cytomegalovirus infections were higher with MMF (6.2% and 10.6% vs. 18.1% p < 0.0001 and p = 0.0139, respectively). FTY720 2.5 mg provided comparable rejection prophylaxis over 12 months versus MMF; however, FTY720 5.0 mg did not support a 50% reduction in cyclosporine exposure. The cause of macular edema cases and lower creatinine clearance with FTY720 in de novo transplantation needs further investigation.

Conversion from mycophenolate mofetil to enteric-coated mycophenolate sodium in maintenance renal transplant patients: preliminary results from the myfortic prospective multicenter study.

Mycophenolate mofetil (MMF), in combination with cyclosporine and corticosteroids, improves long-term graft survival in renal transplant recipients. However, optimal MMF therapy may be limited by gastrointestinal (GI) intolerance, which may result in the need for MMF dose reduction, interruption, or discontinuation, leading to increased risk of acute rejection. Enteric-coated mycophenolate sodium (EC-MPS) is a new formulation delivering mycophenolic acid developed with the aim of improving upper GI tolerability. A large prospective, open-label, multicenter program (myPROMS: myfortic PROspective Multicenter Study) is underway to determine the efficacy and safety of EC-MPS, in combination with cyclosporine microemulsion (CsA; Neoral) in a large population of de novo and maintenance renal transplant recipients. myPROMS consists of one global protocol with 14 subprotocols. Each subprotocol is designed to address further specific objectives, such as specific patient populations, steroid regimens, and various CsA C2 targets. The preliminary data summarized here are from two subprotocols, which investigated the benefits of converting maintenance renal transplant patients receiving MMF to EC-MPS. The 3-month interim analyses suggest that the conversion from MMF to EC-MPS is well tolerated in maintenance renal transplant recipients.

Update on liver transplantation using cyclosporine.

After the introduction of cyclosporine into liver transplantation in 1983, 1-year patient survival more than doubled. Later, with the improved microemulsified formulation of cyclosporine (Neoral) more stable pharmacokinetics were achieved. Today, C(2) monitoring of cyclosporine blood levels allows a more accurate estimation of the area under the concentration-versus-time curve as the single best indicator of cyclosporine exposure. As a consequence, with better control of side effects as well as desired effects the results of cyclosporine in liver transplantation have been further improved. The introduction of mycophenolate mofetil and basiliximab/daclizumab combination therapy has provided new options for the prevention of allograft rejection. The safety profile of individual immunosuppressive regimens comes more into focus since acute allograft rejection may be controlled successfully with competing strategies. As the focus in liver transplantation is shifting toward greatly improved long-term results, late posttransplant mortality with a functioning graft is a major concern. Prevention of long-term complications associated with highly effective immunosuppressants--posttransplant lymphoproliferative disease, cytomegalovirus infection, diabetes, hypertension, and hyperlipidemia-gains importance. Technical advances in living-related and cadaveric split-liver transplantation have lead to increasing use of segmental liver transplantation with the need to consider the effects of immunosuppression on liver regeneration and metabolism. The individualized orchestration of immunosuppression taking into account the underlying liver disease as well as other individual predispositions remains a future challenge.

Severe exacerbation of chronic hepatitis B after emergence of lamivudine resistance in a cirrhotic patient: immediate switch to adefovir dipivoxil appears to be indicated.

INTRODUCTION: Lamivudine is a treatment option for the therapy of chronic hepatitis B with an excellent safety profile. Unfortunately, viral resistance to lamivudine is common in the course of therapy. The lamivudine resistant mutants are usually less pathogenic than the wild type, but development of viral resistance can also lead to acute exacerbation of the underlying hepatitis. The recently FDA approved nucleoside analogue adefovir dipivoxil has potent antiviral activity against lamivudine-resistant mutants and can prevent viral replication effectively. CASE REPORT: A 31-year-old man with pre-existing compensated liver cirrhosis developed resistance to lamivudine therapy leading to subacute liver failure. After referral adefovir dipivoxil 10 mg daily was initiated within an early access protocol. Since initiating therapy with adefovir dipivoxil progression of the subacute liver failure was delayed accompanied by a rapid decrease of ALT and decline of HBV viral load. Even so, the clinical course was not reverted but showed slower deterioration. This enabled the patient to undergo living-related liver transplantation. Adefovir dipivoxil was well tolerated in the acute phase of the disease and did not cause nephrotoxicity or favour the development of hepatorenal syndrome. CONCLUSION: Adefovir dipivoxil resulted in a delay of hepatic decompensation and enabled liver transplantation as final treatment option for this patient. Earlier initiation might even have prevented the need of liver transplantation. Thus, in patients with pre-existing liver cirrhosis an early switch to adefovir dipivoxil appears indicated after emergence of lamivudine resistance.

[Living kidney transplantation. A comparison of Scandinavian countries and Germany].

The discussion of compensating for shortages of cadaveric donation with increased living donation often reveals differences between the Scandinavian countries and Germany. Possible adoption of Scandinavian structures to improve the rate of living donations in Germany warrants analysis of the actual differences between these two regions. Close examination reveals that significantly higher rates of living donation are achieved only in Sweden and Norway. In Norway, a frequently postulated negative effect on cadaveric donation due to very high rates of living donation could not be confirmed. In contrast to Germany and as a consequence of Norwegian geography, kidney transplantation has been regarded in Norway as the first-line therapy for endstage renal disease for more than 35 years. Living donation has since been actively pursued and is traditionally the transplantation of first choice. In Germany, living donation is still regarded as the second choice after cadaveric donation, due to legal regulations. Significant improvements in living donation frequencies could be achieved there by adopting the active Norwegian approach to living donor identification.

[Surgical treatment for hilar cholangiocarcinoma (Klatskin's tumor)].

Surgical treatment of hilar bile duct carcinoma remains difficult, which is due to the inadequate possibilities in assessing tumor extent during the preoperative diagnostic procedure as well as intraoperatively. Radical resection with negative histologic margins offers the best chance for long-term survival. The decision regarding the appropriate surgical approach is challenging due to the complexity of tumor localization and neighboring vascular structures. Aggressive resection demands extended liver resection, which is associated with the risk of postoperative liver failure. However, even limited surgery such as hilar resection can be curative and leads to long-term survival in individual cases. The principles of surgical oncology have led to more aggressive procedures, including the combination of liver transplantation and multivisceral resection, and can be performed with calculable morbidity and mortality. Nevertheless, the high risk of tumor recurrence under long-term immunosuppression, the limited availability of donor organs and the excellent results of liver transplantation in non-malignant diseases do not justify this procedure at present. Neoadjuvant radiochemotherapy has failed to demonstrate major benefit. In patients with irresectable tumor or distant metastases palliative measures are aimed at restoring an unobstructed bile flow with endoscopic placement of metal stents. Palliative treatment with additional radio- or photodynamic therapy may be considered in individual cases.

Successful outcome of acute graft-versus-host disease in a liver allograft recipient by withdrawal of immunosuppression.

BACKGROUND: Graft-versus-host disease (GVHD) after liver transplantation is uncommon, and the outcome is almost always fatal. Since 1987, about 30 cases have been described, and patient survival is mostly exceptional. METHODS: A 29-year-old man underwent retransplantation due to chronic cholestatic syndrome, 5 years after his first liver transplantation. Indication for the first liver transplantation was acute liver failure caused by exsiccosis. After the second transplantation, the patient had an initially uneventful course, developing thrombocytopenia at day 21 followed by skin rash and septic complications. Diagnosis of acute GVHD was made by using serological techniques for HLA-A and HLA-DRB and subsequently by fluorogenic sequence-specific primed polymerase chain reaction. In addition, donor lymphocytes were marked by immunohistochemical methods via biopsies of the skin. Immunosuppressive therapy was withdrawn to allow the patient's own immune system to eliminate donor cells. RESULTS: By withdrawing the immunosuppressive therapy, clinical and morphological signs of GVHD vanished. The patient is doing well without recurrence 13 months after transplantation. CONCLUSION: Withdrawal of immunosuppressive therapy is a promising approach in the treatment of acute GVHD to allow the patient's immune system to reconstitute itself, reject offending lymphocytes, and avoid lethal septic complications.

Clinical and subclinical acute rejection early after liver transplantation: contributing factors and relevance for the long-term course.

Routine transplant aspiration cytology (TAC) after liver transplantation gives detailed information that concerns immunologic events in the graft. TAC can be helpful for diagnosis of acute rejection, but it also detects morphological signs of rejection without clinical correlate ("subclinical rejection"). The aim of this study was to systematically evaluate factors that influence the development of early clinical and subclinical rejection and to analyze the relevance of these early immunologic processes for the long-term course. The study includes the course of 340 patients after liver transplantation between 1988 and 1995 in whom TAC was performed routinely and who were followed for a minimum of 3 years. TAC findings were correlated with the following various clinical parameters: (1) Overall early clinical rejection occurred in 17.4%, subclinical rejection in 59.1%, and no immune activation was seen in 23.5% of patients. (2) Incidence of early clinical and subclinical rejection was markedly influenced by type of immunosuppression. (3) Basic disease and extent of preservation injury had only a minor influence; there was a trend towards lower early rejection associated with more severe preservation damage, increased patient age, and early retransplantation. (4) Presence of early clinical or subclinical rejection was not associated with a higher incidence of chronic dysfunction. (5) Falsely indicated antirejection treatment was associated with inferior graft survival. Subclinical rejection is very frequent early after liver transplantation, requires no treatment, and has no long-term adverse effect. Incidence of early clinical rejection is mainly determined by initial immunosuppression; its occurrence has no negative long-term effects and may even be associated with a lower risk for later immunological complications. Thus, the incidence of early acute rejection is no adequate parameter for evaluating the quality of an immunosuppressive treatment protocol.

Results of 3-year phase III clinical trials with daclizumab prophylaxis for prevention of acute rejection after renal transplantation.

BACKGROUND: Daclizumab (Zenapax, Roche Pharmaceuticals), a humanized monoclonal antibody directed against the alpha chain of the interleukin 2 receptor, has been shown to reduce the incidence of acute rejection at 6 months after renal transplantation in two phase III clinical trials. This report presents the combined 1- and 3-year outcomes of kidney transplant recipients who participated in these two phase III clinical trials. METHODS: Data from two multicenter, randomized, placebo-controlled trials were evaluated with regard to graft survival, patient survival, incidence of malignancies (including lymphoma), renal function (serum creatinine and glomerular filtration rate [GFR]), and current maintenance immunosuppressive regimen. In addition, the impact of acute rejection and acute rejection requiring treatment with antilymphocyte therapy upon 3-year graft survival was evaluated. Daclizumab was compared to placebo on a background of cyclosporine (CsA), azathioprine, and corticosteroids (triple therapy, TT) or CsA and corticosteroids (double therapy, DT). RESULTS: Treatment with daclizumab in the pooled analysis demonstrated a significant reduction in the incidence of biopsy-proven acute rejection episodes at 12 months posttransplant (43% vs. 28%, P<0.001). The 3-year graft survival was not significantly different between placebo and daclizumab-treated patients in the TT trial (83% vs. 84%) or in the DT trial (78% vs. 82%). Pooled patient survival was excellent in both placebo- (91%) and daclizumab- (93%) treated patients. The incidence of malignancies or posttransplant lymphoproliferative disorder (PTLD) in placebo- versus daclizumab-treated groups was comparable in both clinical trials. Renal function was similar between placebo- and daclizumab-treated groups in both the TT and DT trials. The occurrence of delayed graft function, acute rejection requiring antilymphocyte therapy at 6 months, and acute rejection at 12 months posttransplant were associated with decreased graft survival rates at 3 years posttransplant. CONCLUSIONS: The beneficial effect of daclizumab prophylaxis upon the incidence of acute rejection after renal transplant with TT or with DT was not associated with adverse clinical sequelae, including the development of PTLD, at 3 years posttransplant. There was no beneficial effect of daclizumab on graft survival at 3 years, but the trial was inadequately powered to detect this. Both studies showed excellent graft and patient survival at 3 years.

Multicenter trial exploring calcineurin inhibitors avoidance in renal transplantation.

BACKGROUND: The adoption of calcineurin inhibitors (CNI) as the mainstay of immunosuppression has resuited in a significant decrease of acute rejection and improvement of short-term graft survival. However, because of the irreversible nephrotoxicity associated with the chronic use of the CNI, the magnitude of the improvement of long-term graft survival has been more modest. Therefore, an effective immunosuppression regimen that does not rely on CNI may result in improvement of long-term outcome and simplification of the management of transplant recipients. METHODS: Ninety-eight patients of primary cadaver or living donor kidneys at low immunologic risk were enrolled in a CNI avoidance study. The immunosuppression regimen consisted of daclizumab, a humanized monoclonal antibody that binds to the alpha chain of the interleukin-2 receptor (IL-2Ralpha), administered for a total of five doses at biweekly intervals; 3 gm/day mycophenolate mofetil for the first 6 month and 2 gm thereafter; and conventional corticosteroid therapy. Patients who underwent rejection episodes could be started on CNI. The primary efficacy end-point was biopsy-proven rejection during the first 6 months posttransplant. RESULTS: Biopsy-proven rejection was diagnosed in 48% of patients during the first 6 months after transplantation. The majority of rejection episodes were Banff grade I and IIA and were fully reversed with corticosteroid therapy. The median time to the first biopsy-proven rejection among patients who experienced this event during the first 6 months was 39 days. In 22 patients with delayed graft function, the proportion of patients with biopsy-proven rejection was 50% at 6 months. However in the first 2 weeks posttransplant, only 1 of 22 patients with delayed graft function developed biopsy-proven rejection. At 1 year, patient survival was 97% and graft survival was 96%. Only two grafts were lost secondary to rejection. At 1-year posttransplant, 62% of patients had received CNI for more than 7 days. At 1-year posttransplant, the mean serum creatinine in the nonrejectors with no CNI use was 113 micromol/L (95%, confidence interval [CI], 100.7 to 125.3 micromol/L) and in the rejectors or patients with CNI use (more than 7 days) was 154 micromol/L (95% CI, 135.0 to 173.0 micromol/L). In selected patients with rejection, analysis of circulating and intragraft lymphocytes revealed complete IL-2Ralpha saturation. CONCLUSIONS: This CNI avoidance study in immunologic low-risk patients, while only partially successful in preventing acute rejection, provided benefits to a sizable minority of patients who have not required chronic CNI therapy. However, wide acceptance of a CNI-sparing immunosuppression regimen may require a lower rate of acute rejection, possibly through the addition of a non-nephrotoxic dose of CNI. However, because complete IL-2Ralpha blockade was present during rejection, it can be assumed that alternative pathways, such as IL-15, may be responsible for the rejection; thus, the incorporation of non-nephrotoxic immunosuppressive agents, such as sirolimus, may provide a more strategic approach.

Replacement of calcineurin inhibitors with mycophenolate mofetil in liver-transplant patients with renal dysfunction: a randomised controlled study.

BACKGROUND: Renal dysfunction is a major complication of long-term immunosuppressive therapy with calcineurin inhibitors (CNI) in liver-transplant recipients. We undertook a randomised study to assess the safety and efficacy of CNI withdrawal and replacement by mycophenolate mofetil. METHODS: 28 people who had had renal dysfunction attributable to suspected CNI toxicity after liver transplantation participated in the study. We replaced CNI with mycophenolate mofetil in a stepwise pattern in half the group (study patients); the other half (controls) stayed on CNI immunosuppression. Renal function, blood pressure, uric acid, and blood lipids were measured before and 6 months after study entry. Side-effects of medication and graft function were recorded throughout the study. FINDINGS: At the end of the study, mean (SD) serum creatinine had fallen by 44.4 (48.7) micromol/L in study patients compared with 3.1 (14.3) micromol/L in controls; a mean difference of 41.3 micromol/L (95% CI 12.4-70.2). Moreover, systolic and diastolic blood pressure, and serum uric acid decreased significantly in the study group but not in the control group (mean [95% CI] between group differences 10.8 mm Hg [3.0-18.6], 5.0 mm Hg [0.9-9.2], and 83.1 micromol/L [12.7-153.6], respectively). There were no changes in cholesterol or triglyceride concentrations in either group. Side-effects were reported by eight of the study patients. Three reversible episodes of acute graft rejection occurred in study patients during mycophenolate mofetil monotherapy, whereas none occurred in the control group. INTERPRETATION: Substitution of CNI by mycophenolate mofetil can improve renal function, blood pressure, and uric acid concentration of liver-transplant patients, but there is an increased rejection risk with mycophenolate mofetil monotherapy.

A population pharmacokinetic screen to identify demographic-clinical covariates of basiliximab in liver transplantation.

BACKGROUND: Basiliximab is a high-affinity interleukin-2 receptor (CD25) chimeric monoclonal antibody used for immunoprophylaxis in organ transplantation. It was assessed in a randomized, double-blind, placebo-controlled efficacy trial in de novo liver allograft recipients who received 40 mg of basiliximab (20 mg on days 0 and 4) in addition to baseline immunosuppression with cyclosporine (INN, ciclosporin) microemulsion and corticosteroids. METHODS: Serial blood samples (8.3 +/- 1.4 per patient) were collected during 12 weeks after transplantation from 184 basiliximab-treated patients, and empirical Bayes estimates of each patient's disposition parameters were derived. Demographic-clinical covariates were explored with regression methods. RESULTS: Basiliximab clearance was 55 +/- 26 mL/h, the distribution volume was 9.7 +/- 4.2 L, and the half-life was 8.7 +/- 6.7 days. Patient weight, age, sex, ethnicity, history of alcoholism, hepatitis C seropositivity, and notable postoperative bleeding had no clinically relevant influences on basiliximab disposition; however, the cumulative volume of drained ascites fluid in the first week was positively correlated with clearance. Receptor-saturating basiliximab concentrations (> or =0.1 microg/mL) were maintained for 38 +/- 16 days, and this was negatively correlated with the cumulative volume of drained ascites fluid in week 1. Patients who experienced an acute rejection episode did not clear basiliximab at a faster rate than their rejection-free peers nor did they maintain CD25-saturating concentrations for a shorter period. CONCLUSIONS: Although the standard dose regimen of 20 mg of basiliximab on days 0 and 4 after transplantation appears to be appropriate for the majority of patients with liver transplants, a supplemental dose at the end of the first week may be considered for those with substantial (>10 L) postoperative ascites fluid drainage.
