Indications for and outcomes of therapeutic plasma exchange after cardiac transplantation: A single center retrospective study.

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], Pā€‰=ā€‰.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.

Associate Professor of Biostatistics & Bioinformatics

I am an academic statistician with a focus on educational leadership and administration, teaching, mentoring, and collaborative clinical research. I serve as the director of multiple education programs, both formal degree programs and certificate-based training programs. I also provide administrative oversight of multiple graduate degree programs and educational initiatives focusing on clinical and translational science workforce development at the student, staff, and faculty levels.

I have many years of experience with in-person and online teaching across a variety of teaching venues (formal degree programs, domestic and international certificate-based training programs, faculty development seminars, residency/fellowship training programs) and health sciences audiences (medical students, residents, fellows, faculty, and other health professionals), including more than 21 years as a statistics course director in the Duke Clinical Research Training Program.

As a collaborative scientist I have experience with a broad range of clinical research areas and clinical research designs, including observational studies, epidemiology investigations, and randomized clinical trials, including those utilizing web, mobile, and telemedicine-based health behavior interventions. I have collaborated on projects spanning a broad range of clinical research areas, including amyotrophic lateral sclerosis (ALS), post-traumatic stress disorder (PTSD), Prader-Willi syndrome (PWS), prostate cancer, quality of colorectal cancer care, osteoarthritis, lifestyle modification through weight loss, CVD risk reduction through hypertension control, smoking cessation, and substance abuse recovery.
