Pericarditis in Patients With Chronic Graft-vs-Host Disease

Cardiovascular Considerations in Patients Undergoing Hematopoietic Cell Transplantation

OPINION STATEMENT

Cardiac dysfunction is a serious adverse effect of cancer therapies that can interfere with quality of life and impact long-term survival in patients with cancer. Hematopoietic cell transplantation is a potentially curative therapy for many advanced hematologic malignancies and bone marrow failure syndromes, however is associated with several short- and long-term adverse effects, including importantly, cardiovascular toxicities. The goal of this review article is to describe the cardiovascular events that may develop before, during, and after hematopoietic cell transplantation, review risk factors for short- and long-term cardiovascular toxicities, discuss approaches to cardiovascular risk stratification and evaluation, and highlight the research gaps in the consideration of cardiovascular disease in patients undergoing hematopoietic cell transplantation. Further understanding of cardiovascular events and the factors associated with cardiovascular disease will hopefully lead to novel interventions in managing and mitigating the significant long-term burden of late cardiovascular effects in transplant survivors.

Cardiac Graft Versus Host Disease: A Rare or Underrecognized Pathology?

Allogeneic hematopoietic stem cell transplantation is a potentially curative procedure for a variety of hematologic and immunologic disorders. Despite the powerful therapeutic potential, both acute, and chronic toxicities including graft versus host disease (GVHD) and cardiovascular disease can lead to significant short- and long-term morbidity and mortality. While GVHD can affect any organ, cardiac involvement is rarely described in the literature. In this review, we review available literature, and allude to pathophysiology and therapeutic approaches in cardiac GVHD.

Characterization of Pericarditis following Allogeneic Hematopoietic Cell Transplantation

Pericarditis is an uncommon cardiac complication following allogeneic hematopoietic cell transplantation (alloHCT), with limited data characterizing its incidence, presentation, and management. The etiology of pericarditis in this setting is poorly understood and may include conditioning-related toxicity, infection, or graft-versus-host disease (GVHD). The objective of the present study was to characterize the clinical presentation, management, and outcomes of post-alloHCT pericarditis observed at a single center. This retrospective case-control study of consecutive adults undergoing alloHCT over 5 years was conducted to identify patients who developed pericarditis. Pericarditis was diagnosed using clinical, electrocardiography, and echocardiography findings. Identified cases were compared with a cohort of patients who underwent alloHCT during the same period but did not develop pericarditis. A total of 620 patients underwent alloHCT over the 5-year period, 20 of whom developed pericarditis (3.2% incidence). One patient had a pre-alloHCT history of pericarditis. All but 3 patients had received anthracycline therapy and 1 patient had received chest irradiation before undergoing alloHCT. Patients with pericarditis were more likely than patients without pericarditis to have received total body irradiation (odds ratio [OR], 4.57; P = .003) or cyclophosphamide (OR, 2.35; P = .07) as conditioning or GVHD prophylaxis. Fourteen patients experienced their initial episode of pericarditis before day +100 post-alloHCT, with a median time to onset at day +7. Six patients had their initial episode on day +100 or later, with a median time to onset at day +268. Only 1 patient had active, previously diagnosed GVHD, and 3 patients were on systemic steroid therapy at the time of pericarditis diagnosis. Pericarditis was treated primarily with colchicine (median duration 91 days). Seven episodes of recurrence occurred in 5 patients. Two patients experienced cardiac tamponade following their initial diagnosis, and 3 developed tamponade at recurrence. Recurrence was more common in patients who received no or <90 days of colchicine compared with those who received ≥90 days (45.5% vs 0%; P = .02). No cardiac-related deaths occurred. Overall survival was 85% at a median follow-up of 30 months post-alloHCT. Pericarditis occurred in 3.2% of patients in this single-center study, with cases observed both before and after day +100 and some cases occurring ≥1 year after alloHCT. Colchicine was an effective intervention, with ≥90 days of treatment associated with reduced recurrence. Pericarditis should be considered in patients presenting with chest pain following alloHCT.

Left Ventricular Systolic Function in Long-Term Survivors of Allogeneic Hematopoietic Stem Cell Transplantation

Background

Allogeneic hematopoietic stem cell transplantation (allo-HSCT), a potentially curative therapy for malignant and nonmalignant diseases, is being increasingly used in younger patients. Although allo-HSCT survivors have an established increased risk of cardiovascular disease, there is limited knowledge of the long-term effects on cardiac function in survivors.

Objectives

The purpose of this study was to describe left ventricular (LV) systolic function in long-term allo-HSCT survivors treated in childhood, adolescence, or early adulthood.

Methods

Our cross-sectional cohort study included 104 patients (56% women), age 18 ± 10 years at time allo-HSCT with 17 ± 6 years of follow-up. Echocardiography included 2-dimensional (2D) and 3-dimensional (3D) analyses and speckle tracking imaging. In total, 55 healthy control subjects with a similar age, sex, and body mass index were used for comparison. Left ventricular systolic dysfunction (LVSD) was defined as reduced 2D left ventricular ejection fraction (LVEF) of <52% in men and <54% in women, and/or a reduced global longitudinal strain (GLS) of ≥−17%. Multivariable linear regression was used to determine independent predictors of 2D-LVEF and GLS.

Results

Allo-HSCT survivors had significantly reduced LV systolic function compared with control subjects: 2D-LVEF (55.2 ± 5.8% vs. 59.0 ± 2.9%; p < 0.001), 3D LVEF (54.0 ± 5.1% vs. 57.6 ± 2.7%; p < 0.001), and GLS (−17.5 ± 2.2% vs. −19.8 ± 1.4%; p < 0.001). LVSD was found in 44.2%, of whom 28.3% were symptomatic. Clinical factors independently associated with 2D-LVEF and/or GLS included age, anthracyclines, graft versus host disease (GVHD), heart rate, and hypertension. In the 45% of survivors pre-treated with anthracyclines, the effect of anthracyclines on 2D-LVEF and GLS was dose-dependent.

Conclusions

LVSD is common in long-term survivors of allo-HSCT treated in their youth. Pre-HSCT therapies with anthracyclines, age, heart rate, hypertension, and graft versus host disease are associated with measures of LV function.

Pericardectomy after pericarditis constrictiva led to onset of transplant kidney function after 98 days of anuric kidney graft: a case report

BACKGROUND

Constrictive pericarditis is easily overlooked and can lead to severe problems in hemodynamics and end-organ perfusion, in our patient leading to 98 days of anuria after living kidney transplantation. This was completely reversible after pericardectomy.

CASE PRESENTATION

A 43-year-old female caucasian patient received a living kidney donation from her mother. She had developed end-stage renal disease 2 years prior due to nephrotic syndrome linked to graft-versus-host disease after allogenic stem-cell transplantation for aplastic anemia. The graft showed insufficient function already in the early postoperative phase. Dialysis was paused after surgery, but the patient developed hypervolemia with ascites and edema in the lower extremities. Doppler ultrasonography showed scarce perfusion, with intrarenal arterial waveforms without end-diastolic flow. The venous perfusion profiles showed pulsatile retrograde flow. There was no identifiable reason for a primary vascular perfusion problem on ultrasonography or transplant kidney angiography. Kidney transplant biopsy revealed no rejection but extensive acute tubular necrosis. Three weeks after transplantation, the patient developed an acute anuric graft failure caused by severe cardiac decompensation. Echocardiography revealed a previously unnoticed constrictive pericarditis, which could be confirmed in a cardio computed tomography scan. The constrictive pericarditis had not been apparent on previous x-rays, computed tomography scans, or echocardiographies, including those for transplantation evaluation. Conservative management of the constrictive pericarditis was not successful and the graft remained anuric. Eventually, the patient underwent pericardectomy 16 weeks after kidney transplantation. Shortly after surgery, the graft started urine production again, which significantly increased within a few days. The clearance improved and 2 weeks later, the patient was free from dialysis.

CONCLUSIONS

This case illustrates that special attention should be given to the pericardium during transplant evaluation, especially for patients who previously underwent stem-cell transplantations, chemotherapy or radiation.
