Results of heart transplantation in recipients with active infection.

Although active infection in the recipient is generally considered to be an absolute contraindication for heart transplantation, seven of our first 104 transplant patients (6.7%) had active severe infection within the week before transplantation. Because of unstable clinical condition of these recipients, heart transplantation was performed when an adequate donor was offered, in spite of infection. Patients were managed with cyclosporine as the only immunosuppressive therapy during the first week after transplantation. Mortality rate and incidence of acute rejection were not different for these seven patients than for the remaining 97 patients.

A randomized study comparing deflazacort and prednisone in heart transplant patients.

Prednisone is widely used by most heart transplantation units despite its frequent side effects. Deflazacort, an oral synthetic steroid with fewer side effects, has been successfully used in patients after heart transplantation, but a prospective study comparing deflazacort and prednisone in transplant patients is lacking. We have carried out, in the last year, a prospective trial of deflazacort versus prednisone involving 35 consecutive heart transplant patients. Two of these patients died perioperatively (surgical mortality, 5.7%), and another two were excluded from the protocol because of diabetes mellitus in one patient and active infection before transplantation in the other patient. Thus 31 patients were enrolled in the 3-month study. All of them were treated with antithymocyte globulin, 10 mg/kg/day for 3 days after transplantation, azathioprine, and cyclosporine; patients were randomly assigned groups: 15 patients to receive deflazacort therapy, 1.5 mg/kg/day, and 16 patients to receive prednisone therapy, 1 mg/kg/day, starting the first day after transplantation. Steroids were rapidly tapered, reaching the maintenance dose at 2 to 3 weeks after transplantation (prednisone, 0.15 mg/kg/day; deflazacort, 0.25 mg/kg/day). Both groups were similar in terms of age, gender, ABO identity, serum cyclosporine levels, azathioprine dosage, and pretransplantation serum glucose and lipids levels. Seven endomyocardial biopsies were performed on each patient, at 1, 2, 3, 5, 7, 10, and 13 weeks after transplantation. Incidence of acute rejection was similar between prednisone and deflazacort groups; 33% of patients receiving prednisone therapy and 42% of patients receiving deflazacort therapy had one episode of 3A or higher rejection (not significant).(ABSTRACT TRUNCATED AT 250 WORDS)

Influence of heart transplantation on the natural history of patients with severe congestive heart failure.

In an attempt to study the influence of heart transplantation on the natural history of patients with severe congestive heart failure, we have reviewed our experience with 240 consecutive patients who were New York Heart Association class IV or III/IV, who had left ventricular ejection fraction less than 35%, who were younger than 65 years of age, and who were assessed for heart transplantation in our hospital since May 1986. Mean age was 47 +/- 12 years. Left ventricular ejection fraction was 20% +/- 6%. Eighty-seven percent were male. New York Heart Association class was IV in 88% and III/IV in 12%. The cause was ischemic heart disease in 35% of patients, valvular heart disease in 13% of patients, and primary dilated cardiomyopathy in 52% of patients. At initial assessment, heart transplantation was considered to be not indicated in 30% of patients, indicated in 51% of patients, and contraindicated in 19% of patients. During a follow-up of 13 +/- 13 months (2 to 64 months), 110 patients underwent transplantation (46%). Posttransplantation actuarial probability of survival was 70% at 3 years. Three-year probability of survival free from transplantation was significantly lower for patients older than 55 years of age (p < 0.05), for those with left ventricular ejection fraction less than 20% (p < 0.05), ischemic causes (p < 0.05), New York Heart Association class IV (p < 0.001), and indication/contraindication for transplantation (p < 0.001); no difference was noted for gender.(ABSTRACT TRUNCATED AT 250 WORDS)

Actuarial Analysis↗

Preliminary experience with deflazacort, a new synthetic steroid with fewer undesirable side effects, in heart transplant patients.

Prednisone is widely used by most heart transplant units, despite its frequent side effects. Deflazacort, a new oral synthetic steroid with fewer side effects, has not been studied in heart transplant patients. Our initial experience with 26 heart transplant patients in whom prednisone was replaced by deflazacort at 11 +/- 11 months after transplantation is reported. After the switch to deflazacort, a significant decreased was noted in glycemia, total cholesterol, and LDL-cholesterol (p < 0.001). No difference was noted in severity or frequency of rejection and infection between patients being treated with deflazacort and another 26 patients who continued to be treated with prednisone over a comparable period of time after transplantation.
