Knowledge of human T cells derives chiefly from studies of peripheral blood, whereas their distribution and function in tissues remains largely unknown. Here, we present a unique analysis of human T cells in lymphoid and mucosal tissues obtained from individual organ donors, revealing tissue-intrinsic compartmentalization of naive, effector, and memory(More)
Intestinal transplantation has been established as a treatment option for patients that suffer from intestinal failure with complications from total parenteral nutrition. It is still rapidly evolving and just reached a landmark of 1,000 cases worldwide. Intestinal allografts can be transplanted as isolated, combined with the liver or as a part of a(More)
BACKGROUND Intrahepatic biliary strictures (IHBS) without hepatic artery thrombosis (HAT) is a serious complication and known to increase the risk of graft failure after liver transplantation. This manuscript describes the incidence, risk factors, clinical pictures, management, and outcomes. METHODS Between 1994 and 2002, 1,113 liver transplantations were(More)
We investigated the role of donor bone marrow cell (DBMC) infusions in immunosuppression withdrawal in adult liver transplantation. Patients enrolled were at least 3 years post-transplantation, with stable graft function. Forty-five (study group: G1) received DBMC, and 59 (control group: G2) did not. Immunosuppression was reduced by one third upon(More)
BACKGROUND The aim of this study was to evaluate the efficacy of lamivudine (LAM) monoprophylaxis for patients with non-replicating hepatitis B virus (HBV) infection at orthotopic liver transplantation (OLT). METHODS Among 128 liver recipients with HBV infection between 1994 and 2004 transplanted at our institution, 60 had non-replicating HBV infection at(More)
BACKGROUND/PURPOSE Severe gastrointestinal dysmotility (GID) impairs patients' quality of life and is almost uniformly fatal after complications of parenteral nutrition. Intestinal and multivisceral transplants have been used as alternative treatment of these disorders. We studied patients with GID treated with transplantation in our center, and reviewed(More)
BACKGROUND The increasing demand for transplantation has resulted in a trend toward using virologically compromised donors. We reviewed our experience with liver grafts from hepatitis-B surface antigen (HBsAg)(-), antibody to core antigen (anti-HBc)(+) donors. METHODS Sixty-two liver transplants using HBsAg(-), anti-HBc(+) donors were studied. The(More)
BACKGROUND Due to the known high recurrence rate of hepatitis C virus (HCV) among orthotopic liver transplant (OLT) recipients who receive tacrolimus+corticosteroid maintenance, use of steroid-free induction was considered. METHODS OLT recipients with HCV were randomized to receive tacrolimus+daclizumab (steroid-free) vs. tacrolimus+corticosteroids during(More)
Mechanisms for human memory T cell differentiation and maintenance have largely been inferred from studies of peripheral blood, though the majority of T cells are found in lymphoid and mucosal sites. We present here a multidimensional, quantitative analysis of human T cell compartmentalization and maintenance over six decades of life in blood, lymphoid, and(More)
BACKGROUND The administration of alemtuzumab (Campath-1H [C1H]; Berlex Laboratories, Montville, NJ) at transplantation prevents a vigorous immune response and is believed to allow a gradual engagement of the host immune system. We report our preliminary experience with C1H and tacrolimus (Tac) immunosuppression in adult liver transplantation. METHODS We(More)
