Abstract
Background The purpose of this study was to test the efficacy and safety of daclizumab (DZM) versus anti-thymocyte globulin (ATG) as a component of induction therapy in heart transplant recipients. Methods Thirty heart transplant patients were randomized to receive either ATG or DZM during induction therapy. Patients in the DZM group received an initial dose of 2 mg/kg intravenous (IV) at the time of transplant and 1 mg/kg IV on postoperative day 4. Discussion Recipient, donor, and intraoperative variables did not differ significantly between groups. The cost of induction therapy, total drug cost, and hospital ward costs were significantly less for the DZM group. Average absolute lymphocyte and platelet counts were significantly higher in the DZM group. There were no significant differences in the incidence of rejection, infection, malignancy, or steroid-induced diabetes. One year survival was excellent in both groups (87%, P = 0.1). Daclizumab is a safe component of induction therapy in heart transplantation.

Abstract
OBJECTIVES Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents. METHODS Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline. CONCLUSIONS It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

Abstract
Purpose To determine whether topical tacrolimus might prove effective in the treatment of refractory anterior segment inflammatory diseases, and to evaluate its efficacy in eyes with ocular graft versus host disease (GVHD), and vernal keratoconjunctivitis (VKC). Methods Twenty-eight eyes of 14 patients with anterior segment inflammation refractory to steroid treatment were treated with 0.03% tacrolimus ointment at the Samsung Medical Center, Seoul, Korea from March 2008 through August 2009. Seven patients had ocular GVHD and seven had VKC. We evaluated the conjunctival and corneal inflammatory change at one, two, four, and eight weeks after treatment with a scoring system. Time to initial response of treatment and therapeutic effect between GVHD and VKC was also analyzed. After the eight-week treatment period, patients were divided into two groups (maintenance group and discontinuance group). Eight patients maintained the treatment for an additional four months, and six patients discontinued the treatments. Therapeutic effect was also compared between the groups at eight weeks and six months after treatment. Results The mean conjunctival and corneal inflammation score was reduced significantly at eight weeks after treatment (p < 0.0001). The therapeutic effect in conjunctival inflammation was first noted at week two after the initial treatment (p = 0.002); reduction in corneal inflammation was first noted at one week (p = 0.0009). When compared according to diagnosis, no therapeutic difference was detected between the groups (p > 0.05). Six months after treatment, we noted no therapeutic differences between the maintenance group and discontinuance group (p > 0.05). Conclusions 0.03% tacrolimus ointment was safe and effective for use in anterior segment inflammatory disease refractory to steroid.

Abstract
Immunosuppression after organ transplantation is complex and ever evolving. Over the past two decades, newer immunosuppressive agents have been introduced with an aim to provide better patient and graft survival. Improved therapeutic strategies have been developed offering the option to use combinations of drugs with non-overlapping toxicities. There are, however, only a few clinical studies with robust data to rationalize the use of these agents in children. This review will discuss the newer immunosuppressive agents used for solid organ transplant, their current status in post-transplant management and prevention of allograft rejection.

Abstract
PURPOSE To investigate the impact of tacrolimus on vascular endothelial growth factor (VEGF) in experimental corneal neovascularization (NV) immunohistochemically. MATERIAL AND METHODS Five groups of seven Wistar albino rats were formed. A silver nitrate cauterization technique was used to induce corneal NV in the study groups, excluding Group 1 (Control Group). Rats in group 1 did not receive any treatment. Rats in group 2 (sham 1) were administered 1 ml of saline intraperitoneally once a day and those in group 3 (sham 2) received one drop of saline four times a day. Rats in group 4 were administered 0.3 mg/kg tacrolimus intraperitoneally once a day. For group 5, 0.3 mg/ml tacrolimus was installed four times a day. Digital photography for each cornea was performed and the percentage area of the NV on the total corneal surface was calculated. The intensity of VEGF immunostaining in the epithelial, the stromal, and endothelial layers was performed in a semi quantitative fashion. RESULTS The mean percentages of the neovascularized areas of intraperitoneally and topically tacrolimus-treated groups were lesser than those of the sham groups (p = 0.002, p = 0.038, respectively). The mean intensity of the epithelial VEGF immunostaining of the intraperitoneally tacrolimus-treated group was less than that of its sham group (p = 0.002), while the mean intensity of the stromal VEGF staining of the topically tacrolimus-treated group was lesser than that of its sham group (p = 0.042). The intensities of the endothelial VEGF immunostaining of the intraperitoneally and topically tacrolimus-treated groups were less than those of the sham groups (p = 0.038, p = 0.032). CONCLUSION Systemic and topical administration of tacrolimus may be beneficial in the prevention of corneal NV because of its effect on VEGF.

Abstract
Lung transplantation is now considered a valid option in the management of end-stage respiratory failure. The postoperative period remains a key stage that will influence the average long-term prognosis of the patients. Primary graft failure, postoperative bleeding, infection, acute rejection and complications linked to the surgery, and to vascular or bronchial anastomoses, are risk factors for mortality and morbidity. These must be taken care of quickly via collaboration with the surgical team. The immunosuppressive treatment essential for tolerance induction with regard to the transplanted organ will be introduced during the intraoperative period and continued for life. The combination of a calcineurin inhibitor, an antiproliferative agent and corticosteroids remains the conventional procedure. The role of new molecules as mTor inhibitors remains to be determined.

Abstract
The optimal maintenance therapy after lung transplantation remains to be established. The aim of this study was to analyse the impact of tacrolimus and mycophenolate mofetil (MMF) as first line immunosuppression on long-term survival and Bronchiolitis Obliterans Syndrome (BOS). From January 1996 through December 2006, all 155 recipients receiving tacrolimus and MMF as maintenance immunosuppression were included in this study. Tacrolimus and MMF was discontinued in 36 patients (23.2%). The overall survival rates were 91.6% at 6 months, 86.4% at 1 year, 74.9% at 3 years, 60.3% at 5 years and 32.4% at 10 years. The overall freedom from acute rejection was 74.6%, 63.2% and 59.4% at 1, 3, and 5 years respectively. The overall BOS-free survival was 95.6% at 1 year, 88.4% at 3 years, 69.5% at 5 years and 30.5% at 10 years. The development of BOS > or = 1 was associated with a significantly increased risk of death and reduced long-term survival. The combination of tacrolimus and MMF offers safe and reliable maintenance immunosuppression after lung transplantation. However, substantial improvements of long-term survival and freedom from BOS might only be achieved by a change in organ allocation policies and patient management beyond differential immunosuppressive protocols.

Abstract
BACKGROUND Progress in composite tissue allotransplantation could provide a new treatment for patients with severe facial disfigurements. We did a partial facial allotransplantation in 2006, and report here the 2 year follow-up of the patient. METHODS The recipient, a 30-year-old man from China, had his face severely injured by a bear in October, 2004. Allograft composite tissue transplantation was done in April, 2006, after careful systemic preparation. The surgery included anastomosis of the right mandibular artery and anterior facial vein, whole repair of total nose, upper lip, parotid gland, front wall of the maxillary sinus, part of the infraorbital wall, and zygomatic bone. Facial nerve anastomosis was done during the surgery. Quadruple immunomodulatory therapy was used, containing tacrolimus, mycophenolate mofetil, corticosteroids, and humanised IL-2 receptor monoclonal antibody. Follow-up included T lymphocyte subgroups in peripheral blood, pathological and immunohistochemical examinations, functional progress, and psychological support. FINDINGS Composite tissue flap survived well. There were three acute rejection episodes at 3, 5, and 17 months after transplantation, but these were controlled by adjustment of the tacrolimus dose or the application of methylprednisolone pulse therapy. Hepatic and renal functions were normal, and there was no infection. The patient developed hyperglycaemia on day 3 after transplantation, which was controlled by medication. INTERPRETATION Facial transplantation could be successful in the short term, but the procedure was not without complications. However, promising results could mean that this procedure might be an option for long-term restoration of severe facial disfigurement.

Abstract
PURPOSE To evaluate the long-term efficacy and side effects of off-label topical tacrolimus 0.03% ointment (Protopic; Fujisawa Health, Deerfield, IL) as a sole second-line immunosuppressive agent in the management of high-risk corneal grafts. METHODS Four consecutive patients underwent high-risk penetrating keratoplasty (4 grafts) with a prior diagnosis of corneal scar secondary to herpetic keratitis, keratoconus, acanthamoeba keratitis, and Fuchs endothelial dystrophy, respectively. All 4 patients developed steroid-induced glaucoma and failed traditional immunosuppressant therapy. Patients were started on topical tacrolimus ointment 0.03%, twice daily, which was tapered to the lowest possible therapeutic dose that maintained its antirejection efficacy. Patients were monitored for adverse treatment effects. The mean follow-up was 33 months (range, 26-48 months), and the mean treatment duration was 22.6 months (range, 13-32 months). RESULTS All 4 high-risk corneal transplant patients experienced episodes of acute rejection that was successfully reversed with topical tacrolimus treatment. During tacrolimus treatment, there were no further episodes of graft rejection and no incidents of herpes simplex virus infection or reactivation, with the longest follow-up being 4 years. Two patients have been successfully tapered off tacrolimus, and 2 patients are currently on once-daily dosing. No adverse effects were observed. CONCLUSIONS Topical tacrolimus 0.03% ointment seems to be a promising second-line immunosuppressant in management of high-risk grafts.

Abstract
BACKGROUND Rejection remains a significant cause of morbidity and mortality after lung transplantation. The purpose of this study was to test the efficacy and safety of daclizumab (DZM) vs anti-thymocyte globulin (ATG) as a component of induction therapy. METHODS Fifty adults undergoing lung transplantation were randomized to receive either ATG or DZM during induction therapy. Patients were followed for 1 year after transplant. RESULTS Although there was no significant difference in the number of acute or chronic rejections between groups, there was a trend toward a delay in time to first acute rejection with DZM induction. Average absolute lymphocytes and average platelet count were significantly higher in the DZM group. Cytomegalovirus (CMV) serology mismatch was higher in the DZM group (7 vs 1, p = 0.05). The DZM group had a greater number of infections (83 vs 47, p = 0.02); however, the number of CMV infections was also significantly greater (18 vs 6, p = 0.03), corresponding to a higher incidence of CMV mismatch. A cost analysis revealed no difference between total drug costs, intensive-care unit (ICU) costs and total hospital costs. One-year survival was 96% in the DZM group and 88% in the ATG group. CONCLUSIONS DZM is a safe component of induction therapy in lung transplantation. In addition, DZM may prolong freedom from acute rejection. Significant infections were more frequent in the DZM group, but this was likely due to a higher incidence of CMV mismatch. Both methods of induction therapy worked well, with excellent 1-year survival.

Abstract
The lung is an anatomically complex vital organ whose normal physiology depends on actively regulated ventilation and perfusion, and maintenance of a delicate blood-air barrier over a huge surface area in direct contact with a potentially hostile environment. Despite significant progress over the past 25 years, both short- and long-term outcomes remain significantly inferior for lung recipients relative to other "solid" organs. This review summarizes the current status of lung transplantation so as to frame the principle challenges currently facing end-stage lung-failure patients and the practitioners who care for them.

Abstract
OBJECTIVES Acute and chronic rejection remain unresolved problems after lung transplantation, despite heavy multidrug immunosuppression. In turn, the strong immunosuppression has been responsible for mortality and pervasive morbidity. It also has been postulated to interdict potential mechanisms of alloengraftment. METHODS In 48 lung recipients we applied 2 therapeutic principles: (1) recipient pretreatment with antilymphoid antibody preparations (Thymoglobulin [SangStat, Fremont, Calif] or Campath [alemtuzumab; manufactured by ILEX Pharmaceuticals, LP, San Antonio, Tex; distributed by Berlex Laboratories, Richmond, Calif]) and (2) minimal posttransplant immunosuppression with tacrolimus monotherapy or near-monotherapy. Our principal analysis was of the events during the critical first 6 posttransplant months of highest immunologic and infectious disease risk. Results were compared with those of 28 historical lung recipients treated with daclizumab induction and triple immunosuppression (tacrolimus-prednisone-azathioprine). RESULTS Recipient pretreatment with both antilymphoid preparations allowed the use of postoperative tacrolimus monotherapy with prevention or control of acute rejection. Freedom from rejection was significantly greater with Campath than with Thymoglobulin (P = .03) or daclizumab (P = .05). After lymphoid depletion with Thymoglobulin or Campath, patient and graft survival at 6 months was 90% or greater. Patient and graft survival after 9 to 24 months is 84.2% in the Thymoglobulin cohort, and after 10 to 12 months, it is 90% in the Campath cohort. There has been a subjective improvement in quality of life relative to our historical experience. CONCLUSION Our results suggest that improvements in lung transplantation can be accomplished by altering the timing, dosage, and approach to immunosuppression in ways that might allow natural mechanisms of alloengraftment and diminish the magnitude of required maintenance immunosuppression.

Abstract
PURPOSE To report 4 cases of patients treated with topical tacrolimus ointment 0.03% for ocular inflammatory conditions refractory to traditional treatment. METHODS Four patients were treated topically with tacrolimus 0.03% ointment twice daily: 2 patients with blepharokeratoconjunctivitis, 1 patient with severe atopic keratoconjunctivitis, and 1 patient with chronic follicular conjunctivitis. RESULTS Three patients had a dramatic improvement of their ocular condition as early as 2 weeks after starting tacrolimus ointment. One patient developed a herpes simplex virus dendrite after 1 week of tacrolimus use. CONCLUSION Tacrolimus ointment appears to be an effective alternative for certain ocular inflammatory conditions refractory to traditional treatments. There may be an increased risk of herpes simplex virus keratitis associated with topical use. Our results support previous literature of patients benefiting from topical tacrolimus use.

Abstract
BACKGROUND Sparse published data exist on outcomes in daclizumab-treated cardiac transplant patients. One trial observed an increased mortality risk 6 and 12 months posttransplant in patients receiving daclizumab plus mycophenolate mofetil (MMF), cyclosporine, and steroids. This study further investigates the safety profile of daclizumab with this same immunosuppressive regimen from a large registry. METHODS Data obtained at hospital discharge on all adult cardiac transplants performed in the USA between January 1998 and October 2003 for patients receiving MMF plus cyclosporine and steroids were accessed from the Scientific Registry of Transplant Recipients. Patients were selected based on induction treatment: daclizumab (n = 684) or no induction (n = 2525). Outcomes were evaluated at 6 months, 12 months, and 3 years posttransplant. Univariate Kaplan-Meier and multivariate Cox models were used to evaluate the effect of treatment on outcomes. Patient survival and infectious death were the primary endpoints. Secondary endpoints included rejection within the first year posttransplant (acute rejection; AR) and total rejection episodes over time. The two treatment groups shared similar demographics and transplant procedure details. RESULTS Daclizumab (vs no induction) patients had no increased risk of patient death nor infectious death. Daclizumab patients had a lower incidence of AR at 6 months (P = .005) and 12 months (P < .001); the adjusted risk for AR at 12 months (hazards ratio [HR] = 0.77; P = .89) and over 3 years (HR 0.83, P = .006) was also lower in daclizumab-treated patients. CONCLUSIONS In cardiac transplant patients, daclizumab (vs no induction) does not result in increased mortality or infectious death, and is associated with a lower incidence of AR.

Abstract
Much progress has been made in heart and lung transplantation over recent decades. The immune mechanisms that result in allograft rejection are now better understood, and the development of immunosuppressant therapies has decreased recipient mortality among transplant recipients. During the 1980s, immunosuppressant therapy primarily involved the use of corticosteroids and cyclosporine. However, while survival rates increased among transplant recipients, many patients experienced primary graft failures, acute and chronic rejection, as well as death. Until the introduction of tacrolimus in the early 1990s, all patients received the same immunosuppressant regimen, regardless of its effectiveness. Tacrolimus therapy has contributed much to the success rates of both heart and lung transplantation, and by 2001, it had become the preeminent immunosuppressant agent used in lung transplantation.
