Extracorporeal Photopheresis With Low-Dose Immunosuppression in High-Risk Heart Transplant Patients-A Pilot Study. Transpl Int 2022; 35:10320.

Abstract
In severely ill patients undergoing urgent heart transplant (HTX), immunosuppression carries high risks of infection, malignancy, and death. Low-dose immunosuppressive protocols have higher rejection rates. We combined extracorporeal photopheresis (ECP), an established therapy for acute rejection, with reduced-intensity immunosuppression. Twenty-eight high-risk patients (13 with high risk of infection due to infection at the time of transplant, 7 bridging to transplant via extracorporeal membrane oxygenation, 8 with high risk of malignancy) were treated, without induction therapy. Prophylactic ECP for 6 months (24 procedures) was initiated immediately postoperatively. Immunosuppression consisted of low-dose tacrolimus (8–10 ng/ml, months 1–6; 5–8 ng/ml, >6 months) with delayed start; mycophenolate mofetil (MMF); and low maintenance steroid with delayed start (POD 7) and tapering in the first year. One-year survival was 88.5%. Three patients died from infection (POD 12, 51, 351), and one from recurrence of cancer (POD 400). Incidence of severe infection was 17.9% (n = 5, respiratory tract). Within the first year, antibody-mediated rejection was detected in one patient (3.6%) and acute cellular rejection in four (14.3%). ECP with reduced-intensity immunosuppression is safe and effective in avoiding allograft rejection in HTX recipients with risk of severe infection or cancer recurrence.

Indications for and outcomes of therapeutic plasma exchange after cardiac transplantation: A single center retrospective study. J Clin Apher 2018; 33:469-479. [PMID: 29524240 PMCID: PMC6105382 DOI: 10.1002/jca.21622] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 01/19/2018] [Accepted: 02/24/2018] [Indexed: 02/01/2023]
Abstract
INTRODUCTION Limited data are available describing indications for and outcomes of therapeutic plasma exchange (TPE) in cardiac transplantation. METHODS In a retrospective study of patients who underwent cardiac transplantation at Duke University Medical Center from 2010 to 2014, we reviewed 3 TPE treatment patterns: a Single TPE procedure within 24 h of transplant; Multiple TPE procedures initiated within 24 h of transplant; and 1 or more TPE procedures beginning >24 h post-transplant. Primary and secondary outcomes were overall survival (OS) and TPE survival (TS), respectively. RESULTS Of 313 patients meeting study criteria, 109 (35%) underwent TPE. TPE was initiated in 82 patients within 24 h, 40 (37%) receiving a single procedure (Single TPE), and 42 (38%) multiple procedures (Multiple TPE). Twenty-seven (25%) began TPE >24 h after transplant (Delayed TPE). The most common TPE indication was elevated/positive panel reactive or human leukocyte antigen antibodies (32%). With a median follow-up of 49 months, the non-TPE treated and Single TPE cohorts had similar OS (HR 1.08 [CI, 0.54, 2.14], P = .84), while the Multiple and Delayed TPE cohorts had worse OS (HR 2.62 [CI, 1.53, 4.49] and HR 1.98 [CI, 1.02, 3.83], respectively). The Multiple and Delayed TPE cohorts also had worse TS (HR 2.59 [CI, 1.31, 5.14] and HR 3.18 [CI, 1.56, 6.50], respectively). Infection rates did not differ between groups but was independently associated with OS (HR 2.31 [CI, 1.50, 3.54]). CONCLUSIONS TPE is an important therapeutic modality in cardiac transplant patients. Prospective studies are needed to better define TPE's different roles in this patient population.

Abstract
The aim of this study was to identify metabolite biomarkers associated with acute rejection after heart transplantation in rats using a LC-MS-based metabolomics approach. A model of heterotopic cardiac xenotransplantation was established in rats, with Wistar rats as donors and SD rats as recipients. Blood and cardiac samples were collected from blank control rats (Group A), rats 5 (Group B) and 7 days (Group C) after heart transplantation, and pretreated rats 5 (Group D) and 7 days (Group E) post-transplantation for pathological and metabolomics analyses. We assessed International Society for Heart and Lung Transplantation (ISHLT) grades 0, 3B, 4, 1 and 1 rejection in groups A to E. There were 15 differential metabolites between groups A and B, 14 differential metabolites between groups A and C, and 10 differential metabolites between groups B and C. In addition, four common differential metabolites, including D-tagatose, choline, C16 sphinganine and D-glutamine, were identified between on days 5 and 7 post-transplantation. Our findings demonstrate that the panel of D-tagatose, choline, C16 sphinganine and D-glutamine exhibits a high sensitivity and specificity for the early diagnosis of acute rejection after heart transplantation, and LC-MS-based metabolomics approach has a potential value for screening post-transplantation biomarkers.

Abstract
BACKGROUND Few studies have examined the impact of patient weight on heart transplant (HT) outcomes. OBJECTIVES Nine outcomes were compared in 2 groups of HT recipients (N = 347) based on their mean body mass index (BMI) during the first 3 years post-HT. METHODS Group 1 consisted of 108 non-overweight patients (BMI <25; mean age 52; 29.6% females; 16.7% minorities). Group 2 consisted of 239 overweight patients (BMI ≥25; mean age 52; 15.9% females; 13.8% minorities). Outcomes were: survival, re-hospitalization, rejections, infections, cardiac allograft vasculopathy (CAV), stroke, renal dysfunction, diabetes, and lymphoma. RESULTS Non-overweight patients had shorter survival, were re-hospitalized more days after the HT discharge, and had more lymphoma and severe renal dysfunction. Overweight patients had more CAV, steroid-induced diabetes, and acute rejections. CONCLUSIONS Overweight HT patients had better survival, but more rejections, CAV, and diabetes. Non-overweight HT patients had worse survival, plus more re-hospitalization time, lymphoma, and renal dysfunction.

Abstract
With improved immunosuppressive regimens, transplantation techniques, and postoperative care, heart transplantation (HTx) has been established as a definite therapy for end-stage heart disease. Because of a donor shortage, we have accepted marginal individuals. In this study, we identified donor-related factors influencing survival after HTx by retrospective analysis of recipient data after primary HTx from February 2002 to December 2006. The Cox regression model was used to examine the effects of the following variables on survival of 112 heart transplant recipients: demographic data of gender, age, body weight, donor-recipient body weight ratio; history of smoking, alcohol drinking, diabetes mellitus, hypertension, hepatitis B surface antigen, anti-hepatitis C virus antibody; donor condication before transplantation including catecholamine doses, hypotension, cardiopulmonary resuscitation, creatine MB isoenzyme of creatine kinase (CK-MB), tropinin I, and cold ischemic time of the allograft. Catecholamines and smoking showed significant influences on HTx survival. In our series, the percentage of donors receiving inotropic support before donation was 88% (n = 99), and the percentage of donors with a history of smoking was 25% (n = 28). There was no influence of donor status of diabetes, hypertension, or hepatitis B or C infection on postoperative survival. Our results showed that inotropic support of and a history of smoking by the donor were significant factors influencing posttransplant survival.

Abstract
BACKGROUND Longstanding morbid obesity can be associated with severe cardiomyopathy. However, the safety and efficacy of bariatric surgery in patients with severe cardiomyopathy has not been studied, and the effect of surgical weight loss on postoperative cardiac function is also unknown. In addition, morbidly obese patients have significantly increased mortality associated with cardiac transplantation, often precluding them from becoming recipients. METHODS A retrospective study of patients with a left ventricular ejection fraction < or =35% who underwent bariatric surgery (1998-2005) was performed. Short-term morbidity/mortality, length of stay, excess weight loss, pre- and postoperative left ventricular ejection fraction, and New York Heart Association (NYHA) functional class were assessed. RESULTS A total of 14 patients (10 men and 4 women) with a mean preoperative body mass index of 50.8 +/- 2.04 kg/m(2) underwent bariatric surgery (10 underwent laparoscopic Roux-en-Y gastric bypass, 1 open Roux-en-Y gastric bypass, 2 sleeve gastrectomy, and 1 laparoscopic gastric banding). The complications were pulmonary edema in 1, hypotension in 1, and transient renal insufficiency in 2. The median length of stay was 3.0 days (range 2-9). The mean excess weight loss at 6 months was 50.4%, with a decrease in the mean body mass index from 50.8 +/- 2.04 kg/m(2) to 36.8 +/- 1.72 kg/m(2). The mean left ventricular ejection fraction at 6 months had significantly improved from 23% +/- 2% to 32% +/- 4% (P = .04), correlating with improved functional capacity, as measured by the NYHA classification. Preoperatively, 2 patients (14%) had an NYHA classification of IV, 6 (43%) a classification of III, and 6 (43%) a classification of II. At 6 months postoperatively, no patient had an NYHA classification of IV, 2 (14%) had a classification of III, and 12 (86%) an NYHA classification of II. Two patients had undergone cardiac transplant evaluations preoperatively and underwent successful transplantation after weight loss. CONCLUSION The results of our study have shown that bariatric surgery for patients with cardiomyopathy is feasible and effective. Surgically induced weight loss results in both subjective and objective improvement in cardiac function. In addition, surgical weight loss can provide a bridge to transplantation in patients who were prohibited secondary to their morbid obesity.

Abstract
OBJECTIVE The objective of this study was to compare baseline characteristics and long-term survival among patients undergoing heart transplantation (HT) according to the 3 main types of prior heart disease: ischemic, idiopathic dilated cardiomyopathy (IDC), and valvular. MATERIALS AND METHODS Four hundred twenty-three HTs performed between 1989 and 2005 were included. We excluded pediatric transplantation, retransplantations, combined transplantations (lung and kidney), and transplantations due to heart diseases other than ischemic, IDC, and valvular. Baseline characteristics of the recipients were analyzed, as well as short-term and long- term survival by groups. Analysis of variance (ANOVA) was used for continuous variables and chi-square was used for categorical variables. Survival analysis was computed using Kaplan-Meier curves and the log-rank test, as well as multivariate analysis using logistic regression. RESULTS The ischemic and valvular heart disease groups were older and had a more frequent history of prior heart surgery and circulatory support at the time of transplantation compared with the IDC group. The incidence of arterial hypertension and dyslipidemia was higher among ischemic heart disease recipients. Survival rates at 30 days did not show significant differences (ischemic, 88%; IDC, 93%; and valvular; 84%; P = .21). Long-term survival rates were greater in the IDC than in the valvular or ischemic heart disease groups (75% vs 65% and 62%, respectively; P = .021). The multivariate analysis showed an association between the IDC group and long-term survival (odds ratio [OR], 0.55; 95% confidence interval [CI] 0.35-0.89; P = .015). CONCLUSIONS (1) Patients showed a different clinical profiles depending on their pretransplantation heart disease. (2) There were no differences in early mortality between the groups. (3) Long-term survival was significantly greater among IDC transplant recipients and similar in ischemic and valvular heart disease transplant recipients.
