Abstract
While tacrolimus (FK506) is currently used as immunosuppression therapy in transplant recipient, the immunological mechanism remains unknown. Herein, the immunoregulatory effects of FK506 were investigated in the physiological status and allogeneic skin transplantation. FK506 cannot significantly alter the functions of innate immune cells (macrophages and neutrophils) and adaptive immune cells (T cells) in the physiological status. However, it can effectively delay allogeneic skin-graft rejection through ameliorating the T cell responses, but not myeloid-derived innate immune cell responses. Importantly, it did not affect the allograft recipient macrophage innate immune defence capacity to bacteria. In clinics, FK506 treatment can significantly control the cytokine production in T cells, but not non-T cells. This study shows targeting calcineurin signalling, FK506, to be essential in inducing allograft tolerance, but not to damage the innate defence capacity, validating the immune cell phenotypes as a potential marker in transplantation following FK506 treatment.

Abstract
Critical illness has consequences for the nervous system. Patients experiencing critical illness are at risk for common global neurologic disturbances, such as delirium, long-term cognitive dysfunction, ICU-acquired weakness, sleep disturbances, recurrent seizures, and coma. In addition, complications related to specific organ dysfunction may be anticipated. Cardiovascular disease presents the possibility for CNS injury after cardiac arrest, sequelae of endocarditis, aberrancies of blood flow autoregulation, and malperfusion. Respiratory disease is known to cause short-term effects of hypoxia and long-term effects after ARDS. Sepsis encephalopathy and sickness behavior syndrome are early signs of infection in patients. In addition, commonly encountered organ dysfunction including uremia, hepatic failure, endocrine, and metabolic disturbances present with neurologic findings which may manifest in the critically ill patient as well.

Abstract
BACKGROUND Increased risk of cardiovascular and cerebrovascular disease in liver transplant recipients results in particular from the side effects of calcineurin inhibitor-based immunosuppressive therapy. Several studies have demonstrated a more favourable outcome for patients receiving tacrolimus (TAC) as compared with ciclosporin (CS). AIM To investigate the effects of conversion from CS to TAC on cardiovascular risk factors and renal function in liver transplant recipients. METHODS In a prospective study, all except two patients had chronic kidney disease stages 2-4 (n = 80), according to estimated glomerular filtration rate using the abbreviated Modification of Diet in Renal Disease equation. RESULTS Conversion was accompanied with a mean decrease of total cholesterol from 194.6 +/- 54.0 mg/dL to 175.8 +/- 44.2 mg/dL (P < 0.001), low density lipoprotein cholesterol from 106.7 +/- 39.2 mg/dL to 90.9 +/- 28.6 mg/dL (P < 0.001) and mean arterial blood pressure values from 102.2 +/- 13.2 mm Hg to 95.9 +/- 11.7 mm Hg (P < 0.001). Renal function remained stable. No cases of de novo diabetes mellitus were identified. The Framingham risk score was significantly reduced from 5.2 +/- 4.4 at baseline to 4.4 +/- 5.3 after 12 months (P = 0.006). CONCLUSIONS Conversion from CS to TAC has been shown to improve the cardiovascular risk profile and may retard further decline of renal function after liver transplantation.

Abstract
Various factors determine the graft- and patient survival after transplantation. HLA-matching and immunological factors are of importance for the short- and long-term survival. Apart from these obvious determinants, nonimmunological factors play an important role in defining the baseline organ quality as well as the recipients' status. The influence of these parameters on graft- and patient survival is still underestimated and is a topic of debate. On account of the increasing acceptance of marginal-donor organs these events are of increasing importance for graft survival and long-term function. We review nonimmunological causes for deteriorated graft function and graft loss after solid organ transplantation.

Abstract
BACKGROUND In end-stage cardiomyopathy where concomitant chronic renal failure is a contraindication for cardiac transplantation (HTx), simultaneous heart and kidney transplantation (HKTx) may be the only feasible therapeutic option. Due to the increased donor shortage, the clinical outcome of combined HKTx patients on tacrolimus-based immunosuppression was assessed and compared with a group of HTx patients. METHODS Three hundred forty-nine HTxs, including 13 (4%) combined HKTxs, were performed since 1995. Two hundred twenty-one HTx and all HKTx recipients received tacrolimus-based immunosuppression. Acute rejection episodes (AREs), infections, renal function and clinical outcome were evaluated. Pre-operative renal diagnoses for HKTx patients included cystic nephropathy (n = 4), glomerulonephritis (n = 4), cytostatica-induced nephropathy (n = 1), chronic rejection after renal transplant (n = 1), reflux nephropathy (n = 2) and chronic calcineurin-inhibitor -induced nephropathy after HTx (n = 1). Twelve patients (92%) were on hemodialysis pre-operatively, 1 underwent implantation of a left ventricular assist device (LVAD) before HKTx. RESULTS After 4.7 +/- 2 years, 92% of HKTx compared with 85% of HTx patients had survived (p = 0.42). Acute cardiac rejection episodes were more frequent in HTx than in HKTx patients (0.04 +/- 0.09 vs 0.02 +/- 0.04 ARE/100 patient-days; p = 0.07). Incidence of infection was comparable (0.3 +/- 0.2 vs 0.5 +/- 0.4 infection/100 patient-days). Freedom from transplant vasculopathy was 100% in the HKTx group compared with 71% in the HTx group after 4 years (p = 0.04). CONCLUSIONS Tacrolimus-based immunosuppression yields promising long-term results in HKTx and HTx. The incidence of transplant vasculopathy seems to be lower after HKTx than after HTx. If these results are secondary to a protective effect of tacrolimus-induced tolerance or of tolerance-associated co-transplantation they will need to be investigated in prospective multicenter trials.

Abstract
The effects of the calcineurin inhibitors tacrolimus (FK506) and cyclosporine (Neoral) on graft survival, function, and metabolic profile were evaluated in 69 patients receiving Neoral (group 1) and 54 patients receiving FK506 (group 2) for maintenance immunosuppression following kidney transplantation. Recipient and donor demographics and induction therapy were comparable, except for a higher number of sensitized patients in group 2 (n = 13). Acute rejection timing, severity, and infection rates and types were similar in both groups. During hospitalization, at 6 months, and at 1 year following transplantation, no significant differences were noted between groups in fasting glucose, serum cholesterol levels, triglyceride levels, or need for insulin or antihypertensive therapy. Mean serum creatinine levels on discharge (1.42 mg/dL +/- 0.14 vs 1.68 mg/dL +/- 0.3), at 1 month (1.45 mg/dL +/- 0.1 vs 1.39 mg/dL +/- 0.11), 3 months (1.46 mg/dL +/- 0.09 vs 1.32 mg/dL +/- 0.14), and 1 year (1.29 mg/dL +/- 0.08 vs 1.19 mg/dL +/- 0.09), but not at 6 months (1.42 +/- 0.37 vs 1.10 +/- 0.07; P = .001), were comparable between groups. The 1-year patient and graft survival rates were 98.3% for group 1 and 94.5% for group 2. When evaluated for acute rejection, infection, and metabolic differences, we conclude that both tacrolimus and cyclosporine are effective and safe calcineurin inhibitors for short-term use in kidney transplantation. A similar study is proposed to evaluate the long-term effects of both agents.

Abstract
A retrospective chart review of 1065 consecutive liver allograft recipients in 11 centers from January 1997 to September 1998 was performed. Patients were followed for 3 years or until graft loss. Patients received either tacrolimus (n = 594), cyclosporine (n = 450) or no calcineurin inhibitor (n = 21). Model for end-stage liver disease (MELD) scores at time of transplant were similar between the two groups. During follow-up, more patients switched from cyclosporine to tacrolimus (26.7%) than from tacrolimus to cyclosporine (12.8%; p < 0.0001). Patient and graft survival were equivalent. Corticosteroid use was more common in cyclosporine-treated patients (p < 0.00001). Patients receiving tacrolimus experienced lower serum creatinine levels at months 3 through 36 (p < 0.0001). Systolic blood pressure was lower in patients receiving tacrolimus (p < 0.001) despite a reduced requirement for anti-hypertensive agents (p < 0.0001). In addition, tacrolimus was associated with lower total cholesterol and triglyceride levels for months 3 through 24 and 3 through 12, respectively (p < 0.01), despite a reduced requirement for anti-hyperlipidemic agents. The incidence of new-onset diabetes mellitus was similar in both groups. While both calcineurin inhibitors were associated with excellent patient and graft survival, renal function, blood pressure and serum lipid levels were significantly better with tacrolimus treatment.

Abstract
Liver transplantation allows to treat patients with end-stage cirrhosis as well as some liver malignancies (small size hepatocellular carcinoma) with a life expectancy exceeding 70 and 60 % at 5 years, respectively. Current immunosuppressive agents make it possible to prevent chronic rejection in more than 90 % of the patients and to preserve an excellent quality of life in most cases. The principal limiting factor for liver transplantation is represented by the scarcity of brain-dead donors. Indeed, despite the selection of those candidates who have the best chance of surviving after transplantation, several months are usually necessary for obtaining a graft and the mortality on the waiting list may reach 10 to 15 %. Organ shortage incited to develop alternatives to conventional transplantation, the most important of which are living donor transplantation and split liver transplantation. Living donor transplantation can be applied to about 20 to 30 % of candidates. Thought initially smaller, the partial graft regenerates and its volume is restored within a few weeks. The results of living donor transplantation in terms of survival are comparable to those of cadaveric transplantation. The risk for the donor has to be lower than 1 % which makes that selection must be especially cautious. Donors must be direct relatives or spouses. Split liver transplantation technique, based on the separation of a cadaveric graft into two functional parts transplanted in two distinct recipients, although attractive, is applicable to less than 25 % of the donors. Education for organ donation in the general population still remains a priority.

Abstract
BACKGROUND It is vital that after, renal transplantation, immunosuppression is efficacious and causes few complications. It is especially important that hyperlipidaemia, hypertension and toxic influences should be avoided because these conditions can reduce patient and transplant survival. Many studies have demonstrated beneficial effects of tacrolimus in comparison with cyclosporine with regard to these conditions. These results have suggested that a conversion to tacrolimus from cyclosporine is advantageous. Our study investigated whether patients with deteriorating renal functions can profit from this conversion. METHODS Thirty patients with a renal transplant were studied retrospectively, using data recorded from 3 years before to 3 years after conversion from cyclosporine to tacrolimus. RESULTS While renal function (glomerular filtration rate [GFR]) deteriorated progressively under cyclosporine, it stabilised and even improved under tacrolimus (creatinine: Delta(Cyc)=+1.4 mg/d; Delta(Tac=)-0.7 mg/dl; GFR: Delta(Cyc)=-35 ml/min; Delta(Tac)=14 ml/min). In addition, uric acid level (7.0 vs. 6.4 mg/dl, p<0.05) and cholesterol level (258 vs. 225 mg/dl, p<0.05) were both significantly lower under tacrolimus. CONCLUSION Conversion from cyclosporine to tacrolimus is recommended for patients with a kidney transplant, in which there has been a progressive fall in renal function. It leads to stabilisation or even improvement of transplant function and a reduction in cardiovascular risk factors.

Abstract
BACKGROUND Focal segmental glomerulosclerosis (FSGS) commonly presents with nephrotic syndrome (NS), and spontaneous remission is rare. NS is a poor prognostic marker for renal survival, and has serious extra-renal complications. Rapid remission using drugs with minimal side effects is desirable. Tacrolimus (Tac) has a more potent immunosuppressive effect and may be less toxic at therapeutic doses than ciclosporin (CsA). Although CsA has a role in the treatment of FSGS, there are limited data regarding the use of Tac monotherapy in this setting, and this is limited to experience in children. METHODS We prospectively report the outcome for six adult patients with FSGS treated with Tac from first presentation with NS, and for a further five adult patients in remission on CsA converted to Tac in an attempt to arrest a progressive decline in renal function on CsA. RESULTS All six patients treated with Tac from presentation with NS achieved remission after 6.5 +/- 5.9 months. The serum albumin for the group increased from 26.8 +/- 4.6 to 37.7 +/- 1.9 g/l (P = 0.003), and there was a significant reduction in the mean 24 h urinary protein excretion from 11.0 +/- 4.5 to 2.8 +/- 2.5 g (P = 0.003). All remissions were partial with a mean reduction in 24 h urinary protein of 75.2 +/- 16.8%. There was a non-significant reduction in MDRD GFR from 71.7 +/- 22.4 to 55.9 +/- 9.7 ml/min/1.73 m(2) (P = 0.07), which manifest within the first 3 months of Tac treatment but renal function was subsequently stable. The mean follow-up for the group was 12.8+/-5.5 months. Two of the five patients converted from CsA to Tac maintained complete remission, and the remaining three patients in partial remission had further reductions in proteinuria. There was an improvement in renal function concomitant with conversion to Tac in each case, with an overall improvement in MDRD GFR for the group of +1.9+/-1.1 ml/min/1.73 m(2)/month. CONCLUSIONS Tac rapidly and effectively induced remission of NS in FSGS. Conversion from CsA to Tac indicates that Tac might be a more potent agent with less nephrotoxicity in this setting.

Abstract
We investigated the relationship between cyclosporine exposure and the presence of cyclosporine-related side effects and assessed the advantage of the cyclosporine concentration 2 h post-dose (C(2)) over pre-dose concentration (C(0)) monitoring. Cyclosporine area-under-the-concentration-time curves were measured during the absorption phase (AUC(0-4 h)) in 49 liver, 28 heart and 26 kidney transplant recipients (time since transplantation >6 years) with or without cyclosporine-related side effects on maintenance therapy. The cyclosporine C(0) correlated well with AUC(0-4) (r=0.77), whereas C(2) levels correlated strongly with AUC(0-4) (r=0.92). Although we observed a trend towards higher CsA concentrations in transplant recipients with side effects than in patients without CsA toxicity, the large majority of those differences were not statistically significant. Thus, as cyclosporine exposure was not clearly related to the presence of side effects, and C(0) correlated fairly with AUC(0-4), the advantage of monitoring cyclosporine treatment using C(2) rather than C(0), may be limited for patients on cyclosporine maintenance therapy.

Abstract
BACKGROUND Tacrolimus (Tac) has immunosuppressant properties similar to those of cyclosporine A (CsA), but it is more potent. At present, however, its immunosuppressive activity in renal transplant recipients with ongoing chronic rejection has not been clarified. METHODS We studied changes in kidney function, mixed lymphocyte culture, cell-mediated lympholysis, cytotoxic antibodies, lymphocyte population, and cytokine response before and after the conversion from CsA to Tac in 14 pediatric renal transplant recipients with chronic rejection. CsA (5.9+/-0.2 mg/kg/d) was replaced by Tac (0.1+/-0.004 mg/kg/d). RESULTS Serum creatinine decreased (2.3+/-0.2-1.9+/-0.2 mg/dL, P <0.005), creatinine clearance increased (36.8+/-2.5-46.1+/-4.4 mL/min/1.73 m, P <0.005), and urinary protein excretion decreased (0.4+/-0.01-0.2+/-0.04 g/24 hr, P <0.03) after 6 months, and these values were maintained after 2 years with Tac treatment. During Tac therapy, anti-donor and anti-control mixed lymphocyte culture decreased 38% and 31% (P <0.05), respectively. Cell-mediated lympholysis did not change. CD3 decreased from 87%+/-2% to 80%+/-2% (P <0.005), and CD8 decreased from 34%+/-3% to 27%+/-2% (P <0.005). The switch to Tac decreased the interferon-gamma production in vitro (P <0.05) and increased tumor necrosis factor-alpha levels (P <0.05). The release of interleukin-10 was strikingly augmented with CsA or Tac therapy (P <0.01), but transforming growth factor-beta secretion was similar. CONCLUSIONS Our data indicate that conversion from CsA to Tac therapy leads to an improvement in renal function without altering key elements of the immunosuppression in children with ongoing chronic rejection.

Abstract
UNLABELLED Extensive clinical use has confirmed that tacrolimus (Prograf) is a key option for immunosuppression after transplantation. In large, prospective, randomised, multicentre trials in adults and children receiving solid organ transplants, tacrolimus was at least as effective or provided better efficacy than cyclosporin microemulsion in terms of patient and graft survival, treatment failure rates and the incidence of biopsy-proven acute and corticosteroid-resistant rejection episodes. Notably, the lower incidence of rejection episodes after renal transplantation in tacrolimus recipients was reflected in improved cost effectiveness. In bone marrow transplant (BMT) recipients, the incidence of tacrolimus grade II-IV graft-versus-host disease was significantly lower with tacrolimus than cyclosporin treatment. Efficacy was maintained in renal and liver transplant recipients after total withdrawal of corticosteroid therapy from tacrolimus-based immunosuppression, with the incidence of acute rejection episodes at up to 2 years' follow-up being similar with or without corticosteroids. Tacrolimus provided effective rescue therapy in transplant recipients with persistent acute or chronic allograft rejection or drug-related toxicity associated with cyclosporin treatment. Typically, conversion to tacrolimus reversed rejection episodes and/or improved the tolerability profile, particularly in terms of reduced hyperlipidaemia. In lung transplant recipients with obliterative bronchiolitis, conversion to tacrolimus reduced the decline in and/or improved lung function in terms of forced expiratory volume in 1 second. Tolerability issues may be a factor when choosing a calcineurin inhibitor. Cyclosporin tends to be associated with a higher incidence of significant hypertension, hyperlipidaemia, hirsutism, gingivitis and gum hyperplasia, whereas the incidence of some types of neurotoxicity, disturbances in glucose metabolism, diarrhoea, pruritus and alopecia may be higher with tacrolimus treatment. Renal function, as assessed by serum creatinine levels and glomerular filtration rates, was better in tacrolimus than cyclosporin recipients at up to 5 years' follow-up. CONCLUSION Recent well designed trials have consolidated the place of tacrolimus as an important choice for primary immunosuppression in solid organ transplantation and in BMT. Notably, in adults and children receiving transplants, tacrolimus-based primary immunosuppression was at least as effective or provided better efficacy than cyclosporin microemulsion treatment in terms of patient and graft survival, treatment failure and the incidence of acute and corticosteroid-resistant rejection episodes. The reduced incidence of rejection episodes in renal transplant recipients receiving tacrolimus translated into a better cost effectiveness relative to cyclosporin microemulsion treatment. The optimal immunosuppression regimen is ultimately dependent on balancing such factors as the efficacy of the individual drugs, their tolerability, potential for drug interactions and pharmacoeconomic issues.

Abstract
BACKGROUND The role of interleukin-2 receptor antibodies as rescue therapy in steroid-resistant rejection (SRR) has not been studied. We evaluated the safety and efficacy of an interleukin-2 receptor antibody, basiliximab (Simulect, Novartis, East Hanover, NJ), in treating SRR in pediatric liver transplant recipients. METHODS This was a prospective study of seven pediatric liver transplant recipients with biopsy-proven SRR who would have otherwise received OKT3 or antithymocyte globulin. The primary immunosuppression consisted of cyclosporine (Neoral, Novartis), azathioprine, and prednisolone in four patients and tacrolimus and prednisolone in three patients who had undergone retransplantation for chronic rejection (n=2) and hyperacute rejection (n=1). Four patients had received two cycles of high-dose steroids, and three patients had received a single cycle; all had been converted to tacrolimus, followed by the addition of mycophenolate mofetil. RESULTS The median time from transplant to SRR was 30 days (range, 8 days-23 months). Five children received two doses of basiliximab (10 mg, 3-7 days apart), and two children received a single dose. Aspartate aminotransferase levels normalized in three children 12, 21, and 30 days after basiliximab treatment. Aspartate aminotransferase levels decreased without normalizing in two children, but there was no further evidence of cellular rejection on repeat biopsies. All five children are rejection-free with a median follow-up of 22 months (range, 5-32 months). Biochemical abnormalities persisted in the remaining two children, and both developed chronic rejection. There were no immediate side effects associated with basiliximab. Two patients were treated empirically for possible cytomegalovirus infection 21 and 57 days after basiliximab treatment, with no evidence of cytomegalovirus disease. CONCLUSION Five of seven pediatric liver transplant recipients with SRR experienced successful outcomes with basiliximab treatment without major side effects, indicating that it is a safe alternative to OKT3 and other antilymphocyte antibodies.

Abstract
Prevention and control of graft rejection remain essential in the investigation of peripheral nerve allotransplantation. Although use of cyclosporin A (CsA) has been shown to suppress successfully the rejection of nerve allografts, limited information exists concerning use of this drug to arrest rejection in progress, and thereby effect salvage of these grafts. The aim of this study was to determine the efficacy of CsA in the treatment of ongoing acute rejection of peripheral nerve allografts. Buffalo rats received posterior tibial nerve grafts from either Lewis or Buffalo donor animals and were divided into five groups: group 1 received isografts and no CsA treatment (n = 8), group 2 received allografts with continuous CsA therapy (n = 10), group 3 received allografts with no treatment (n = 7), group 4 received allografts with initiation of CsA therapy delayed until 3 weeks after the procedure (n = 11), and group 5 received allografts with an interrupted course of CsA (n = 15). All grafts were harvested at 10 weeks. Histomorphometric analysis demonstrated comparable nerve regeneration in groups 1 and 2 and good regeneration in group 3 animals, despite cellular infiltrate suggestive of rejection. At 3 weeks after surgery, group 4 animals showed early rejection and significantly less neuroregeneration than positive controls at 10 weeks after delayed initiation of CsA therapy. Finally, group 5 animals showed early regeneration at 3 weeks but significantly lesser regeneration by 10 weeks after interruption of therapy. In this experimental protocol, CsA was ineffective in rescuing histologically proven rejection in progress.
