Background: After heart transplantation, 1-year and 5-year survival rates are 79% and 63%, respectively, with rejection, infection, and allograft coronary artery disease accounting for the majority of deaths. Mycophenolate mofetil (MMF), an inhibitor of the de novo pathway for purine biosynthesis, decreases rejection in animals and in human renal transplantation.
Methods: In a double-blind, active-controlled trial, 28 centers randomized 650 patients undergoing their first heart transplant to receive MMF (3000 mg/day) or azathioprine (1.
Background: Cutaneous malignancies are frequent in organ transplant recipients. We retrospectively reviewed a large series of heart transplant recipients and report on the prevalence and risk factors for development of cutaneous squamous and basal cell carcinoma.

Objective And Methods: A retrospective chart review was performed on all patients undergoing orthotopic cardiac allograft transplant at Oregon Health Sciences University. Our purpose was to evaluate the incidence of gastrointestinal complications in these patients, and to assess the effect of immunosuppression.
Results: From December, 1985, to June, 1994, 240 recipients underwent 250 orthotopic cardiac allograft transplants at Oregon Health Sciences University with a 30 day mortality of 15 patients (6.
To determine if cardiac allograft outcome is improved among patients with fewer HLA-DR mismatches with their donors, we studied 132 recipients of a primary cardiac allograft who were transplanted between December 1985 and December 1991. These recipients and their donors all had high-confidence-level serological HLA-DR typing, previously shown to correlate highly with DNA DR typing. Patients were divided in two groups based on the HLA-DR mismatch with their donors.

A significant proportion of potential transplant recipients have undergone previous cardiac procedures and may be subject to an increased risk because of technical and other factors inherent in a reoperation. Between December 1985 and June 1991, 155 orthotopic heart transplantations were carried out in 146 patients. Eighty-five transplantations (54.

From December 1985 to June 1992, 188 cardiac grafts were orthotopically transplanted into 178 recipients. Of these grafts, 38.

However, the specificity of otherwise normal qualitative coronary angiography for excluding cardiac allograft vasculopathy has not been prospectively studied. Accordingly, 28 patients who underwent transplantation from June 23, 1989 to July 9, 1990 underwent coronary angiography within 3 weeks (predischarge) after transplantation and at 1 year.

Limited clinical experience concerning heart transplantation across ABO blood group barriers suggests a high incidence of hyperacute rejection and poor patient outcome. Reported is a case of the short-term survival of an ABO-mismatched cardiac graft without evident adverse immunologic effects. A 41-year-old man with blood type O underwent heart transplantation receiving a blood type A2 donor organ.

Of the 328 cardiac allograft recipients, 11 (3.4%) had an IgG positive crossmatch.

Of 142 cardiac allograft recipients who underwent transplantation from December 1985 to January 1991, four women and seven men (mean age, 41 +/- 14 years) required multiple (10.5 +/- 3.3) courses of antirejection treatment over a total follow-up period of 30 +/- 15 months.

The difficulties in interpreting these studies include the variety of methods used for the diagnosis of cytomegalovirus infection and variable criteria for the diagnosis of cardiac allograft vasculopathy. To determine whether specific aspects of cytomegalovirus infection are risk factors for cardiac allograft vasculopathy, the patient population of the Oregon Cardiac Transplant Program was analyzed for the following variables: cytomegalovirus infection, primary cytomegalovirus infection, and persistent cytomegalovirus infection for 4 or 6 months documented by either blood or urine cultures and persistent cytomegalovirus viremia for 4 months.

We undertook a controlled trial to evaluate the prophylactic administration of ganciclovir to prevent CMV-induced disease after heart transplantation.
Methods: This randomized, double-blind, placebo-controlled trial was conducted at four centers.
Potent prophylactic immunosuppressive protocols promote the safe withdrawal of corticosteroid maintenance. The benefits of corticosteroid-free maintenance immunosuppression include the absence of the cushingoid habitus, fewer infections, less obesity, and lower serum cholesterol. The incidence of allograft coronary artery disease is not increased by corticosteroid-free maintenance.
View Article and Find Full Text PDFAlthough the etiology of allograft coronary artery disease, a major limiting factor in long-term survival after cardiac transplantation, is poorly understood, it is undoubtedly in part immune mediated and not detected by routine endomyocardial biopsy. Therefore it is possible that withdrawal of maintenance corticosteroids, although providing other short- and long-term benefits, could increase the prevalence of allograft coronary artery disease by permitting undetected immune-mediated vascular injury to occur. To assess whether corticosteroid-free maintenance immunosuppression increased the prevalence of allograft coronary artery disease, we reviewed serial angiograms of 102 patients (49% not receiving corticosteroid maintenance therapy) who underwent heart transplantation after March 7, 1985.
