Cancer-free survival following alemtuzumab induction in heart transplantation.

BACKGROUND: The malignancy rate after alemtuzumab (C-1H) induction in cardiac transplantation is unknown. METHODS: A retrospective analysis from a single center for all patients that underwent cardiac transplantation from January 2000 to January 2011 and that had no history of malignancy before transplantation was performed. Patients induced with alemtuzumab were compared with a group of patients receiving thymoglobulin or no induction and assessed for 4-year cancer-free post-heart transplantation survival. RESULTS: Of 402 patients included, 185 (46.0%) received alemtuzumab, 56 (13.9%) thymoglobulin, and 161 (40.0%) no induction. Baseline characteristics did not differ between groups: mean age 54.0 years, male 77.1%, white 88.6%, ischemic cardiomyopathy 49.0%. The calcineurin inhibitor was tacrolimus in 98.9% of alemtuzumab patients, 98.2% of thymoglobulin patients, and 87.0% of the noninduced (P < .001). The secondary agent was mycophenolate mofetil in all but 16 noninduced patients (9.9%), who received azathioprine. The 4-year cancer-free survival did not differ between groups: 88.1% alemtuzumab, 87.5% thymoglobulin, 88.2% noninduction; P = .088. The 4-year nonskin cancer-free survival was 96.8% for the alemtuzumab group, 96.4% for the thymoglobulin group, and 95.7% for the noninduced; P = .899. CONCLUSIONS: Neither the 4-year cancer-free survival nor the 4-year nonskin cancer-free survival differed between the alemtuzumab, thymoglobulin, and noninduced groups.

Alemtuzumab induction prior to cardiac transplantation with lower intensity maintenance immunosuppression: one-year outcomes.

Induction therapy with alemtuzumab (C-1H) prior to cardiac transplantation (CTX) may allow for lower intensity maintenance immunosuppression. This is a retrospective study of patients who underwent CTX at a single institution from January 2001 until April 2009 and received no induction versus induction with C-1H on a background of tacrolimus and mycophenolate. Those with C-1H received dose-reduced calcineurin inhibitor and no steroids. A total of 220 patients were included, 110 received C-1H and 110 received no induction. Recipient baseline characteristics, donor age and gender were not different between the two groups. Mean tacrolimus levels (ng/mL) for C-1H versus no induction: months 1-3 (8.5 vs. 12.9), month 4-6 (10.2 vs. 13.0), month 7-9 (10.2 vs. 11.9) and month 10-12 (9.9 vs. 11.3) were all significantly lower for the C-1H group, p < 0.001. There were no differences between the C-1H and no induction groups at 12 months for overall survival 85.1% versus 93.6% p = 0.09, but freedom from significant rejection was significantly higher for the C-1H group, 84.5% versus 51.6%, p < 0.0001. In conclusion, induction therapy after CTX with C-1H results in a similar 12 month survival, but a greater freedom from rejection despite lower calcineurin levels and without the use of steroids.

Relapsing bacteremia in patients with ventricular assist device: an emergent complication of extended circulatory support.

BACKGROUND: Ventricular assist devices (VAD) are currently approved for use as a bridge for transplantation. Although reports have suggested acceptable rates of survival of patients with VAD, there is little information regarding the mechanism and etiology of bacteremia in these patients. METHODS: We prospectively followed patients who underwent VAD implantation and developed bacteremia during VAD support at the University of Pittsburgh Medical Center. Relapsing bacteremia was defined as at least two episodes of positive blood cultures with a genetically related organism on 2 different days. Species identification and susceptibility testing were performed on all isolates. Pulse field gel electrophoresis was performed on selected blood and VAD isolates. RESULTS: Between January 1998 and August 1999, 3 patients with VAD developed relapsing bacteremia, which was treated with full courses of antibiotic agents, 2 of whom also developed VAD endocarditis. All 3 patients had documented driveline or device pocket infections with these isolates. Consecutive blood and VAD isolates were found to be genetically related within each patient. CONCLUSIONS: These patients with bacteremia after VAD implantation had relapse due to the same strain, which may have originated from indolent driveline infection. Endovascular infection in this setting is difficult to eradicate with antibiotic agents and carries a high mortality. These patients should be considered to have priority for orthotopic heart transplantation.

HeartMate II left ventricular assist system: from concept to first clinical use.

The HeartMate II left ventricular assist device (LVAD) (ThermoCardiosystems, Inc, Woburn, MA) has evolved from 1991 when a partnership was struck between the McGowan Center of the University of Pittsburgh and Nimbus Company. Early iterations were conceptually based on axial-flow mini-pumps (Hemopump) and began with purge bearings. As the project developed, so did the understanding of new bearings, computational fluid design and flow visualization, and speed control algorithms. The acquisition of Nimbus by ThermoCardiosystems, Inc (TCI) sped developments of cannulas, controller, and power/monitor units. The system has been successfully tested in more than 40 calves since 1997 and the first human implant occurred in July 2000. Multicenter safety and feasibility trials are planned for Europe and soon thereafter a trial will be started in the United States to test 6-month survival in end-stage heart failure.

Database: relevant or not.

Progress in the field of ventricular assist devices requires a more rigorous and systematic method of collecting outcomes data. A worldwide registry of device implants and results is proposed. With widespread participation, data from this registry would improve the identification of risk factors and complications, and allow for the creation of predictive models that would enhance patient selection. Professional societies should lead the development of a registry in close partnership with government and industry. Data collection using the Web, with rigorous security measures to protect patient privacy, would offer numerous advantages in efficiency and immediacy of communication for all participants.

Cardiac transplantation in survivors of lymphoma: a multi-institutional survey.

BACKGROUND: Cardiac transplantation has been successfully performed in patients with a history of presumably cured Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). Though the risk of recurrence is a major concern, the long-term influence of prior cancer and cancer therapy on posttransplant outcome has not been previously investigated. METHODS: Questionnaires were sent to 130 cardiac transplant centers in the United States registered with the United Network for Organ Sharing. Data collected included patient demographics; type, stage, and timing of HD/NHL; treatment for HD/NHL; posttransplant immunosuppressive regimen, rejection history, and outcomes; and Epstein-Barr virus status. RESULTS: Thirty-four cardiac transplant recipients with a previous history of HD (n=16) or NHL (n=18) were identified. HD patients averaged 41+/-15 years of age, with a mean disease-free interval of 15+/-9 years at the time of transplantation. NHL patients averaged 42+/-17 years of age with a mean disease-free interval of 10+/-9 years at the time of transplantation. The mean follow-up for the entire group was 50 months (range, 2 days to 136 months), and mean follow-up for the survivors was 67 months (range, 23-136 months). The 1-, 3-, 5-, 7-, and 10-year actuarial survival estimates for the entire group are 77%, 64%, 64%, 64%, and 50%, respectively. Actuarial survival was lower in HD patients (P=0.04) and in patients who had previously undergone splenectomy (P=0.008). Cox regression analysis identified only prior splenectomy (P=0.02) as an independent risk factor for mortality after cardiac transplantation with an adjusted relative risk of 6.2 (1.7-21.9, 95% confidence intervals). CONCLUSIONS: Although the numbers are small, these data strongly suggest that there is an increased mortality risk for cardiac transplant recipients with prior HD who have undergone splenectomy.

Effects of donor bone marrow infusion in clinical lung transplantation.

BACKGROUND: We have demonstrated that donor cell chimerism is associated with a lower incidence of obliterative bronchiolitis (OB) in lung recipients, and that donor chimerism is augmented by the infusion of donor bone marrow (BM). We herein report the intermediate results of a trial combining the infusion of donor BM and lung transplantation. METHODS: Clinical and in vitro data of 26 lung recipients receiving concurrent infusion of donor bone marrow (3.0 to 6.0 x 10(8) cells/kg) were compared with those of 13 patients receiving lung transplant alone. RESULTS: Patient survival and freedom from acute rejection were similar between groups. Of the patients whose graft survived greater than 4 months, 5% (1 of 22) of BM and 33% (4 of 12) of control patients, developed histologic evidence of OB (p = 0.04). A higher proportion (but not statistically significant) of BM recipients (7 of 10, 70%) exhibited donor-specific hyporeactivity by mixed lymphocyte reaction assays as compared with the controls (2 of 7, 28%). CONCLUSIONS: Infusion of donor BM at the time of lung transplantation is safe, and is associated with recipients' immune modulation and a lower rate of obliterative bronchiolitis.

A clinical trial combining donor bone marrow infusion and heart transplantation: intermediate-term results.

BACKGROUND: Donor chimerism (the presence of donor cells of bone marrow origin) is present for years after transplantation in recipients of solid organs. In lung recipients, chimerism is associated with a lower incidence of chronic rejection. To augment donor chimerism with the aim to enhance graft acceptance and to reduce immunosuppression, we initiated a trial combining infusion of donor bone marrow with heart transplantation. Reported herein are the intermediate-term results of this ongoing trial. METHODS: Between September 1993 and August 1998, 28 patients received concurrent heart transplantation and infusion of donor bone marrow at 3.0 x 10(8) cells/kg (study group). Twenty-four contemporaneous heart recipients who did not receive bone marrow served as controls. All patients received an immunosuppressive regimen consisting of tacrolimus and steroids. RESULTS: Patient survival was similar between the study and control groups (86% and 87% at 3 years, respectively). However, the proportion of patients free from grade 3A rejection was higher in the study group (64% at 6 months) than in the control group (40%; P =.03). The prevalence of coronary artery disease was similar between the two groups (freedom from disease at 3 years was 78% in study patients and 69% in controls). Similar proportions of study (18%) and control (15%) patients exhibited in vitro evidence of donor-specific hyporesponsiveness. CONCLUSIONS: The infusion of donor bone marrow reduces the rate of acute rejection in heart recipients. Donor bone marrow may play an important role in strategies aiming to enhance the graft acceptance.

Development of the Nimbus/University of Pittsburgh innovative ventricular assist system.

BACKGROUND: Nimbus Inc, and the University of Pittsburgh's McGowan Center for Artificial Organ Development have been collaborators on rotary blood pump technology initiatives since 1992. Currently, a major focus is an innovative ventricular assist system (IVAS) that features an implantable, electrically powered axial flow blood pump. In addition to the blood pump, a major development item is the electronic controller and the control algorithm for modulating pump speed in response to varying physical demand. METHODS: Methods used in developing the IVAS include computational fluid dynamic modeling of the pump's interior flow field, flow visualization of the flow field using laser-based imaging, computer simulation of blood pump-physiological interactions, vibroaccoustic monitoring, and an extensive in vivo test program. RESULTS: Results to date, which are presented below, include successful in vivo tests of blood pumps with blood-immersed bearings, and feasibility demonstration of vibroacoustic monitoring in this application. CONCLUSIONS: This unique blend of industrial experience and technologies with the University-based Research and Development Center has greatly enhanced the progress made on this IVAS project.

Evaluation of the potential role of color-coded tissue Doppler echocardiography in the detection of allograft rejection in heart transplant recipients.

BACKGROUND: Color-coded tissue Doppler (TD) echocardiography can noninvasively quantify alterations in left ventricular (LV) systolic and diastolic function. The objective of this study was to test the hypothesis that TD may play a role in the detection of LV dysfunction associated with allograft rejection in heart transplant recipients. METHODS AND RESULTS: Seventy-eight consecutive transplant recipients underwent 89 TD studies of posterior wall myocardial velocity gradient and mitral annular velocity within 1 hour of endomyocardial biopsy. Color TD echocardiographic images were digitized for semiautomated computer analysis. Histologic analysis revealed no significant rejection in 75 biopsies and significant rejection in 14. TD posterior wall peak systolic and diastolic velocity gradients were reduced significantly with rejection: 3.9 +/- 2.0 s(-1) versus 2.6 +/- 0.9 s(-1) and 5.4 +/- 2. 4 s(-1) versus 3.5 +/- 1.6 s(-1), respectively (P <.05 vs the nonrejecting group). Peak systolic and diastolic mitral annular velocities by TD were also reduced with rejection: 63 +/- 14 mm/s versus 49 +/- 12.4 mm/s and 90 +/- 23 mm/s versus 60 +/- 21 mm/s, respectively (P <.001 vs the nonrejecting group). A TD peak-to-peak mitral annular velocity >135 mm/s had 93% sensitivity, 71% specificity, and 98% negative predictive value for detecting rejection. Although TD was unable to discriminate between rejection and other causes of low velocity values, high TD velocity values were supportive of excluding rejection. CONCLUSIONS: These data suggest that color-coded TD may play a potential role as a screening test to exclude rejection in heart transplant recipients. Although this method has the potential to decrease the number of biopsies, further testing in a larger series of transplant recipients with rejection is warranted.

Early post-transplant medical compliance and mental health predict physical morbidity and mortality one to three years after heart transplantation.

BACKGROUND: Poor medical compliance has been held responsible for a large proportion of deaths occurring subsequent to initial postoperative recovery. However, beyond clinical reports, there has been little empirical examination of this issue, or of the extent to which major psychiatric disorder and failure to adjust to the transplant predict long-term physical morbidity and mortality. We prospectively examined whether a full range of compliance behaviors and psychiatric outcomes during the first year post-transplant predicted subsequent mortality and physical morbidity through 3 years post-transplant. METHODS: A total of 145 heart recipients who had received detailed compliance and mental health assessments during the first year post-transplant were followed up at 3 years post-transplant. Interview data and corroborative information from family members were used to determine compliance in multiple domains, psychiatric diagnoses, and psychiatric symptomatology during the first year post-surgery. Medical record reviews were performed to abstract data on acute graft rejection episodes, incident cardiac allograft disease (CAD) and mortality from 1 to 3 years post-transplant. RESULTS: After controlling for known transplant-related predictors of outcome, multivariate analyses yielded the following significant (p < 0.05) results: (a) risk of acute graft rejection was 4.17 times greater among recipients who were not compliant with medications; (b) risk of incident CAD was elevated by persistent depression (Odds Ratio, OR = 4.67), persistent anger-hostility (OR = 8.00), medication noncompliance (OR = 6.91), and obesity (OR = 9.92); and (c) risk of mortality was increased if recipients met criteria for Post-Traumatic Stress Disorder related to the transplant (OR = 13.74). CONCLUSIONS: The findings, plus data we have previously reported that showed which patients are most likely to have compliance and psychiatric problems early post-transplant, suggest that interventions focused on maximizing patients' psychosocial status in these areas may further improve long-term physical health outcomes in this population.

Traumatic aortic rupture: diagnosis and management.

BACKGROUND: Traumatic aortic rupture is a relatively uncommon lesion that presents the cardiothoracic surgeon with unique challenges in diagnosis and management. To address controversial aspects of this disease, we reviewed our experience. METHODS: The study was performed by retrospective chart review. RESULTS: Forty-two patients with traumatic thoracic aortic ruptures were managed between January 1988 and June 1997. Nine arrived without vital signs and died in the emergency department. Admission chest radiographs were normal in 3 patients (12%) and caused significant delays in diagnosis. Four of 30 patients admitted with vital signs had rupture before thoracotomy and died. Twenty-six underwent aortic repair. In 1 patient repair was performed with simple aortic cross-clamping, whereas a second was managed with a Gott shunt. The remaining 24 patients had repair with partial left heart bypass. In 1 patient hypothermic circulatory arrest was required. Two patients (7.7%) died. There were no cases of new postoperative paraplegia in the bypass group. There was no morbidity directly attributable to the administration of heparin for cardiopulmonary bypass. CONCLUSIONS: In a discrete group of patients with traumatic rupture of the aorta, the rupture will become complete during the first few hours of hospital admission; aggressive medical treatment with beta-blockade and vasodilators in the interval before the operation is an essential aspect of management. Active distal circulatory support with partial left-heart bypass provides the optimal means of preventing spinal cord ischemia during repair of acute traumatic aortic rupture.

Predicting short-term outcome in severely ill heart failure patients: implications regarding listing for urgent cardiac transplantation and patient selection for temporary ventricular assist device support.

BACKGROUND: The purpose of this study was to determine which patients on a cardiac transplantation list required a ventricular assist device. METHODS AND RESULTS: In a preliminary study, 26 patients with decompensated severe New York Heart Association class IV chronic heart failure were studied. Blood levels for sodium, hemoglobin, cytokines, neurohormones, and hemodynamics were obtained. During short-term follow-up of 40 days, 12 patients had undergone emergent implantation of a ventricular assist device (range 1-27 days, mean 5 days), 4 died (range 14-38 days, mean 26 days), and 5 were alive and receiving only medical therapy while waiting for a transplantation. In addition, five patients had undergone transplantation (range 5-29 days, mean 18 days, excluded from further analysis). Survival curves were constructed by comparing the incidence of death and the implantation of an emergent ventricular assist device in patients with values of a variable above or below the mean value (or median for nonnormally distributed data). There was a significantly greater incidence of death or need for a ventricular assist device in patients with higher levels of tumor necrosis factor-alpha (P = .008), lower levels of serum sodium and hemoglobin (P = .02 and P = .03, respectively), higher heart rates (P = .03), and higher plasma norepinephrine levels (P = .01). The Cox proportional hazards model demonstrated that only serum sodium (P = .03) independently predicted those patients who died or who required emergent left ventricular assist device. CONCLUSION: Numerous variables, particularly serum sodium, need to be considered when evaluating which patients on the transplant list require early assist device implantation or urgent transplantation. These preliminary observations merit confirmation in a larger patient population.

Fine trabecularized carbon: ideal material and texture for percutaneous device system of permanent left ventricular assist device.

The development of a percutaneous artificial internal organ system requires a reliable biocompatible connection between the external environment and the inside of the human body. Such is necessary for the success of a permanent left ventricular assist device. However, the search for a satisfactory interface at the epidermal level has proven to be difficult. Carbon has been proposed for this application, but its texture does not typically promote ingrowth from surrounding tissue. We have therefore employed a new processing method to produce a fine trabecularized carbon implant. The method for preparing the implant involves infiltrating low temperature pyrolytic carbon into the surface of a carbon core which is wrapped with carbon fabric. This results in a tightly woven porous structure of carbon (carbon fiber diameter: 35-50 microm, maximal pore size >200 microm) with gradually increasing porosity from 15-75%. We implanted test samples percutaneously in a calf for in vivo histological evaluation. Thirty days after implantation epidermal downgrowth was minimal. Microscopic analysis revealed that a thin fibrous capsule surrounded the implant, and mature connective tissue with accompanying blood vessels filled the pores of the fine trabecularized carbon layer. From these results we suggest that fine trabecularized carbon is ideally suited for a percutaneous device system in a permanent left ventricular assist device.

Monocyte tissue factor expression and ongoing complement generation in ventricular assist device patients.

BACKGROUND: Ongoing complement activation in patients with a ventricular assist device may contribute to observed hemostatic abnormalities and cellular aggregation by mediating leukocyte and platelet activation, formation of leukocyte-platelet conjugates, and the tissue factor pathway of coagulation. METHODS: Blood from 30 patients was collected before ventricular assist device implantation and during the implantation period. Plasma levels of thrombin-antithrombin III complexes, C3a, and SC5b-9 were measured by commercial enzyme-linked immunosorbent assay. Flow cytometry was used to measure circulating monocyte tissue factor expression and circulating monocyteplatelet and granulocyte-platelet conjugates. RESULTS: Thrombin-antithrombin III complex level and monocyte tissue factor expression peaked in the early postoperative period, with maxima occurring on postoperative days 5 and 3, respectively. Levels of C3a and SC5b-9 remained dramatically elevated over normal values for the duration of the study (6 and 5 times upper normal, respectively). Levels of monocyte-platelet conjugates were normal before implantation, decreased during the first 4 postoperative days, and then increased and remained elevated. Levels of granulocyte-platelet conjugates were elevated over the normal range before implantation and remained elevated from postoperative days 3 to 21. A positive correlation was found between levels of SC5b-9 and granulocyte-platelet conjugates (Spearman R=0.66; p < 0.001), and between levels of C3a and thrombin-antithrombin III complex (Spearman R=0.13; p=0.021). CONCLUSIONS: The data suggest a model in which complement mediates formation of leukocyte-platelet aggregates and may indirectly contribute to thrombin generation through monocyte tissue factor expression.

Abciximab and excessive bleeding in patients undergoing emergency cardiac operations.

BACKGROUND: Abciximab (ReoPro; Eli Lilly and Co, Indianapolis, IN) is a monoclonal antibody that binds to the platelet glycoprotein IIb/IIIa receptor and produces powerful inhibition of platelet function. Clinical trials of abciximab in patients undergoing coronary angioplasty have demonstrated a reduction in thrombotic complications and have encouraged the widespread use of this agent. We have observed a substantial incidence of excessive bleeding among patients who receive abciximab and subsequently require emergency cardiac operations. METHODS: The records of 11 consecutive patients who required emergency cardiac operations after administration of abciximab and failed angioplasty or stent placement were reviewed. RESULTS: The interval from the cessation of abciximab administration to operation was critical in determining the degree of coagulopathy after cardiopulmonary bypass. The median values for postoperative chest drainage (1,300 versus 400 mL; p < 0.01), packed red blood cells transfused (6 versus 0 U; p = 0.02), platelets transfused (20 versus 0 packs; p = 0.02), and maximum activated clotting time (800 versus 528 seconds; p = 0.01) all were significantly greater in the early group (cardiac operation < 12 hours after abciximab administration; n = 6) compared with the late (cardiac operation >12 hours after abciximab administration; n = 5) group. CONCLUSIONS: This report suggests that the antiplatelet agent abciximab is associated with substantial bleeding when it is administered within 12 hours of operation.

The CardioWest total artificial heart bridge to transplantation: 1993 to 1996 national trial.

BACKGROUND: We performed a controlled study of a total artificial heart in bridge to transplantation. We hypothesized that the CardioWest total artificial heart used in a selected population of decompensating cardiac transplantation candidates would result in improved survival compared with matched controls. METHODS: The CardioWest trial started in 1993 in six United States institutions under an investigational device exemption from the Food and Drug Administration. Four centers contributed 27 implant and 18 matched retrospective control patients. RESULTS: Of the implant patients, 25 (93%) received a transplant, 24 (89% of the total, 96% of those transplanted) were discharged and are currently surviving. In the control group, 10 patients died awaiting transplantation, 8 received a transplant, and 7 were discharged with 6 surviving (p = 0.00001). All adverse events were documented with respect to time. Thirteen serious adverse events occurred, 11 of which occurred in the 2 patients that died during implant. CONCLUSIONS: In a selected group of patients with endstage heart disease, use of the CardioWest total artificial heart is lifesaving. When compared with the series of matched retrospective controls, a significant improvement in survival was found in the CardioWest implant group.

Cardiac operations in solid-organ transplant recipients.

BACKGROUND: The success of solid organ transplantation has resulted in an increasing pool of patients that subsequently require cardiac surgical procedures, yet the perioperative management of these patients is not well documented. We report a single institutional experience with the management techniques used and the outcomes of the cardiac surgical procedures performed in solid organ transplant recipients with functioning allografts. METHODS: Sixty-four patients underwent 66 cardiac procedures broken down as follows: coronary artery bypass grafting, 30; single or combined valve replacement-repair, 24; combined coronary artery bypass grafting and valve repair, 3; aortic repair, 4; pericardiectomy, 3; transmyocardial laser revascularization, 1; and native cardiectomy, 1. Patients consisted of 40 kidney, 16 liver, 5 heart, 2 lung, and 1 liver and kidney transplant recipients. The mean interval from the time of transplantation to the cardiac operation was 53 months (range, 1 day to 220 months). Forty-six male and 18 female patients in New York Heart Association functional class III or IV had a mean age of 53 years (range, 19 to 77 years); 50% (32/64) were diabetic, and 97% (62/64) were hypertensive. Immunosuppressive therapy, cardiopulmonary bypass, and medical management were similar in all patients. RESULTS: There were two (3%) perioperative deaths, one of which was caused by an arrhythmia-induced cardiac arrest, and there were seven (11%) late deaths from non-cardiac-related causes. Major complications included 12 infections (19%), ten mediastinal reexplorations for the control of bleeding (16%), and nine others (15%). Sixteen of the 64 (25%) transplant recipients had chronic renal failure (serum creatinine levels, > 3 mg/dL), including 13 of 40 (33%) kidney transplant patients. Acute renal failure developed postoperatively in 7 (54%) of these 13 patients; the grafts failed permanently in 3 (23%). Three patients (5%), 2 kidney transplant recipients and 1 lung transplant recipient, experienced transient acute rejection. Fifty of the 55 surviving patients are alive and well (New York Heart Association functional class I or II) without recurrent cardiac disease at a mean follow-up period of 22 months. CONCLUSIONS: Although the short-term morbidity was significant, the low mortality and low incidence of permanent graft dysfunction indicate that solid organ transplant recipients can safely and effectively undergo subsequent cardiac surgical procedures.
