BACKGROUND: After renal transplantation, there is a need of immunosuppressive regimens that effectively prevent allograft rejection while minimizing cardiovascular complications. This substudy of the TRITON trial evaluated the cardiovascular effects of autologous bone marrow–derived mesenchymal stromal cells (MSCs) in renal transplant recipients. METHODS AND RESULTS: Renal transplant recipients were randomized to MSC therapy, infused at weeks 6 and 7 after transplantation, with withdrawal at week 8 of tacrolimus or standard tacrolimus dose. Fifty‐four patients (MSC group=27; control group=27) underwent transthoracic echocardiography at weeks 4 and 24 after transplantation and were included in this substudy. Changes in clinical and echocardiographic variables were compared. The MSC group showed a benefit in blood pressure control, assessed by a significant interaction between changes in diastolic blood pressure and the treatment group (P=0.005), and a higher proportion of patients achieving the predefined blood pressure target of <140/90 mm Hg compared with the control group (59.3% versus 29.6%, P=0.03). A significant reduction in left ventricular mass index was observed in the MSC group, whereas there were no changes in the control group (P=0.002). The proportion of patients with left ventricular hypertrophy decreased at 24 weeks in the MSC group (33.3% versus 70.4%, P=0.006), whereas no changes were noted in the control group (63.0% versus 48.1%, P=0.29). Additionally, MSC therapy prevented progressive left ventricular diastolic dysfunction, as demonstrated by changes in mitral deceleration time and tricuspid regurgitant jet velocity. CONCLUSIONS: MSC strategy is associated with improved blood pressure control, regression of left ventricular hypertrophy, and prevention of progressive diastolic dysfunction at 24 weeks after transplantation.

risk of renal transplant recipients. 2 CNI-based therapy is associated with adverse cardiovascular effects including hypertension, dyslipidemia, and new-onset diabetes. 2 Moreover, the CNI-induced nephrotoxicity increases the risk of cardiovascular complications and chronic allograft dysfunction in renal transplant recipients. 3 Therefore, after renal transplantation, there is a clear need of immunosuppressive regimens that effectively prevent graft rejection while preserving renal function and minimizing cardiovascular side effects.

Mesenchymal stromal cells (MSCs) have immunosuppressive properties and contribute to tissue repair. Several experimental studies demonstrated that MSCs may increase levels of regulatory T cells and polarize the immune system toward tolerance. 4, 5 Moreover, phase I studies have shown that MSCs are safe and effective in renal transplant recipients. [6] [7] [8] [9] MSCs seem also to exert regenerative capacities of the myocardium after an ischemic damage and have been proposed as potential treatment for heart failure. 10 In addition, a growing body of evidence suggested that everolimus, a mammalian target of rapamycin inhibitor, may reduce cardiovascular complications after renal transplantation, 11 minimizing CNI exposure and possibly exerting direct cardioprotective effects. [12] [13] [14] [15] [16] [17] The safety and feasibility of autologous bone marrow-derived MSC therapy combined with everolimus and complete tacrolimus withdrawal after renal transplantation was demonstrated in the TRITON trial. 18 However, the cardiovascular effects of such strategy in comparison with standard of care (CNI-based therapy) have not been evaluated. In this substudy of the TRITON trial, we compared the cardiovascular effects of MSC therapy combined with everolimus and complete withdrawal of tacrolimus versus standard of care (tacrolimus-based therapy).

The data that support the findings of the present study are available from the corresponding author upon reasonable request. The protocol of TRITON trial was approved by the local ethics committee at the Leiden University Medical Center, Leiden, and by the Central Committee on Research Involving Human Subjects in the Netherlands. 18 Written informed consent was obtained from all participants.

In this echocardiographic substudy of the TRITON trial, a 24-week investigator-initiated, randomized, prospective, open-label, single-center clinical study, patients who underwent transthoracic echocardiography at 4 and 24 weeks after renal transplantation were included. The description of the trial and the main results have been previously published. 18 In brief, 70 adult recipients of a first kidney transplant from a living donor were enrolled between March 2014 and January 2020 and randomly assigned before transplantation to either MSC therapy with concomitant early withdrawal of tacrolimus or standard tacrolimus dose (control group) in a 1:1 ratio ( Figure S1 ). Patients in the MSC group received 2 doses of autologous bone marrowderived MSCs (1-2×10 6 per kilogram body weight) intravenously at weeks 6 and 7 after transplantation, in combination with everolimus and prednisolone. At the time of the second MSC infusion, the dose of tacrolimus was reduced to 50% and completely withdrawn 1 week later. Patients in the control group received everolimus, prednisolone, and tacrolimus. The tacrolimus target was 8 to 12 ng/mL the first 6 weeks after transplantation and lowered to 6 to 8 ng/mL in the control group 7 weeks after transplantation. Moreover, all patients enrolled in the study received alemtuzumab CLINICAL PERSPECTIVE What Is New?

• In renal transplant recipients, mesenchymal stromal cells therapy combined with early tacrolimus withdrawal safely improves blood pressure control, compared with a standarddose tacrolimus treatment, at 24 weeks after transplantation. • After renal transplantation, the combination of mesenchymal stromal cells therapy and early tacrolimus withdrawal attenuates adverse left ventricular remodeling, characterized by myocardial hypertrophy and diastolic dysfunction.

What Are the Clinical Implications?

• Mesenchymal stromal cells therapy with complete discontinuation of tacrolimus appears a promising approach in renal transplant recipients, effective in the prevention of graft rejection, while exerting potential cardioprotective effects. • Further studies are warranted to determine the impact of this promising immunosuppressive regimen on long-term cardiovascular outcomes.

CNI calcineurin inhibitor DBP diastolic blood pressure LVM left ventricular mass MSC mesenchymal stromal cell SBP systolic blood pressure (anti-CD52), 15 mg subcutaneously, at days 0 and 1, to minimize the risk for acute rejection. Patients who did not receive the allocated treatment because of abnormal MSC growth, contraindication for prednisone usage, or for MSC infusion during the COVID-19 pandemic, as well as patients from whom a baseline renal biopsy was not obtained and patients who withdrew informed consent were excluded ( Figure 1 ).

Changes in echocardiographic variables between 4 and 24 weeks after renal transplantation were evaluated and compared between the randomization arms.

All patients were followed-up in a dedicated outpatient clinic and treated according to a predefined target of care: systolic blood pressure (SBP) <140 mm Hg and diastolic blood pressure (DBP) <90 mm Hg. The mean blood pressure was obtained by averaging 3 repeated measurements in a sitting position after a 5-minute rest, using an automated monitor. Blood pressure, weight, estimated glomerular filtration rate (eGFR) calculated by the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) formula, 19 and concomitant medications were recorded 4 and 24 weeks after the renal transplantation.

Comprehensive transthoracic echocardiography was performed using a commercially available system (E95 System; General Electric-Vingmed, Horten, Norway) equipped with the 4Vc-D matrix cardiac probe. With the patients at rest in the left recumbent or supine position, 2-dimensional and color, spectral continuousand pulsed-wave Doppler images were obtained from the parasternal, apical, and subcostal windows. All images were digitally stored for offline analysis (EchoPAC version 203; General Electric-Vingmed).

The left ventricular (LV) linear dimensions were measured on the parasternal long-axis view at enddiastole and end-systole. Subsequently, the LV mass was calculated according to the Devereux formula and indexed for body surface area. 20 LV hypertrophy was defined as an LV mass (LVM) index >115 g/m 2 for men and >95 g/m 2 for women. 21 In addition, from the apical 2-and 4-chamber views zoomed on the left ventricle, the LV end-diastolic and end-systolic volumes were measured and indexed for body surface area, and LV ejection fraction was calculated using the biplane Simpson method. The left atrial volume was obtained from the apical 2-and 4-chamber views using the biplane Simpson method and indexed for body surface area. From a zoomed parasternal long-axis view, the LV outflow tract diameter was measured in early systole at the level of aortic cusp insertion. The LV outflow tract time-velocity integral was recorded on the apical 5-chamber view, with the sample volume positioned 5 mm proximal to the aortic valve. Stroke volume was calculated by multiplying the LV outflow tract area by the LV outflow tract time-velocity integral and indexed for body surface area. 22 The assessment of LV diastolic function included the measurement of the ratio between the transmitral early (E wave) and late (A wave) diastolic filling velocities and deceleration time of the E wave on pulsedwave Doppler recording of the mitral inflow from the apical 4-chamber view. 23 In addition, using pulsedwave tissue Doppler imaging, the early diastolic septal and lateral mitral annular velocities (E′) were measured and averaged. The ratio of the transmitral E wave to E′ (E/E′ ratio), a marker of LV filling pressures, was calculated. 24 Additionally, from color Doppler data of the tricuspid valve flow on a right ventricular-focused 4-chamber apical view, the presence of tricuspid regurgitation was assessed, and on continuous-wave Doppler of the regurgitant jet, the peak jet velocity was measured. Pulmonary artery systolic pressure (PASP) was estimated from the tricuspid regurgitant jet velocity using the simplified Bernoulli equation and adding the estimated right atrial pressure: PASP=4(v) 2 +right atrial pressure, where v is the peak velocity (in meters per second) of the tricuspid regurgitant jet and right atrial pressure is estimated from diameter and respiratory changes of the inferior vena cava. 25 

Normally distributed continuous variables are presented as mean±standard deviation, whereas nonnormally distributed data are presented as median and interquartile range. Categorical variables are displayed as frequencies and percentages.

Changes in clinical and echocardiographic variables within each randomization arm were assessed by the paired Student t test (for normally distributed continuous variables), Wilcoxon test (for nonnormally distributed continuous variables), and McNemar test (for categorical variables). The treatment effect (MSC therapy versus tacrolimus-based therapy) was evaluated for each clinical and echocardiographic variable using an ANCOVA model, adjusted for baseline variable. Additionally, a separate extension of the simple ANCOVA model was performed for echocardiographic variables that were statistically significant in the first model including baseline SBP, DBP, eGFR, weight, and the use of an angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (ACE-I/ARB) as covariates. Finally, a sensitivity analysis was conducted for the evaluation of treatment effect on changes in LVM index, excluding 1 patient in the control group who experienced a disproportionate worsening of the LV hypertrophy. All statistical analyses were 2-sided, and P<0.05 was considered statistically significant. In addition, for the analysis of treatment effect on clinical and echocardiographic variables, Bonferroni correction for multiple comparisons was performed, and adjusted significant threshold has also been provided.

Data analysis was performed using SPSS version 25.0 (IBM, Armonk, NY).

Of 57 patients randomized to MSC therapy (n=29) or to control (n=28), 54 patients underwent transthoracic echocardiography at 4 and 24 weeks after renal transplantation and were included in the present subanalysis ( Figure 1 ). One patient randomized to MSC therapy developed acute rejection and tacrolimus was reintroduced, whereas 2 other patients (1 randomized to MSC therapy and 1 control) did not undergo the 24-week echocardiogram. Patient survival during the study follow-up was 100% in both groups. The baseline characteristics of the patients in each randomization arm are summarized in Table 1 .

Changes in clinical variables between 4 and 24 weeks after transplantation for each randomization group are presented in Table 2 . At 24 weeks after transplantation, patients in the MSC group did not show significant changes in DBP, whereas patients in the control group had higher values of DBP compared with baseline, leading to a significant difference between groups (P=0.005). On the contrary, SBP values remained unchanged in both randomization groups. At 24 weeks after transplantation, a higher proportion of patients achieved the predefined blood pressure target of <140/90 mm Hg in the MSC therapy group compared with the control group (59.3% versus 29.6%, P=0.03). There were no significant differences in antihypertensive treatment used between the 2 treatment groups (Table S1) .

Additionally, at 24 weeks after transplantation, patients in the MSC therapy group had a lower eGFR compared with baseline, whereas the eGFR remained unchanged in the control group (P=0.345).

Changes in echocardiographic variables between 4 and 24 weeks after transplantation for each randomization group are presented in Table 3 . Between 4 and 24 weeks after transplantation, a reduction in LVM index was observed in the MSC therapy group, whereas in the control group, there were no significant changes in the LVM index over time, leading to a significant difference between groups (P=0.002) (Figures 2 and 3 , Figure S2 ). The association between changes in LVM index and treatment group remained significant after correcting for baseline SBP, DBP, weight, eGFR, and the use of ACE-I/ARB (P=0.011). A sensitivity analysis performed excluding 1 outlier detected in the control group ( Figure S2 At 24 weeks after transplantation, patients randomized to the control group showed an increase in LV end-diastolic volume index and LV end-systolic volume index with a reduction in LV ejection fraction, whereas patients randomized to MSC therapy did not have relevant changes in these variables (Table 3) . However, these differences were not statistically significant.

When evaluating LV diastolic function, patients in the control group presented a prolongation of E-wave deceleration time at 24 weeks after transplantation, whereas E-wave deceleration time did not change in the MSC therapy group, leading to The association between changes in E-wave deceleration time and treatment group remained significant after correcting for baseline SBP, DBP, eGFR, weight, and the use of ACE-I/ARB (P=0.010). Furthermore, tricuspid regurgitant jet velocity reduced at 24 weeks after transplantation in the MSC therapy group and increased in the control group, and these opposite changes resulted in a significant difference between groups (P=0.001). Nevertheless, changes in tricuspid regurgitant jet velocity were not significantly different between groups when correcting for baseline clinical variables and the use of ACE-I/ARB (P=0.433).

The present study showed that MSC therapy combined with early tacrolimus withdrawal in renal transplant recipients is associated with: (1) improved blood pressure control, (2) regression of LV hypertrophy, and (3) prevention of progressive LV diastolic dysfunction compared with a tacrolimus-based regimen.

Renal transplant recipients have an increased risk of cardiovascular morbidity and mortality. 1 Poor systemic blood pressure control, LV diastolic dysfunction, and atherosclerosis-related complications are frequently observed in renal transplant recipients and may impair renal function, accelerating allograft failure. 26 Current immune-suppressive treatment is effective in preventing rejection but contributes to the increased risk of cardiovascular complications that ultimately may have an impact on the clinical outcomes of kidney transplant recipients. CNIs increase systemic arterial hypertension through several mechanisms, including endothelin-mediated systemic vasoconstriction, impaired vasodilatation secondary to a reduction in nitric oxide, and afferent arteriolar vasoconstriction, mediated by the upregulation of the renin-angiotensinaldosterone system and the sympathetic nervous system. 27 Poor blood pressure control has been associated with chronic graft failure in renal transplant recipients. 28, 29 Moreover, systemic arterial hypertension is the main risk factor for both worsening and de novo occurrence of LV hypertrophy after renal transplantation. 30 LV hypertrophy is a common finding among kidney transplant recipients, with a prevalence ranging from 50% to 70% of patients [31] [32] [33] [34] and is a strong predictor of both all-cause mortality and new-onset heart failure. 30 However, it is important to note that CNIwithdrawal immunosuppressive regimens are effective in reducing the prevalence of systemic arterial hypertension with a subsequent improvement in LV function but with an increased rate of graft rejection. 35 These results underscore the need for alternative immunosuppressive treatments that minimize cardiovascular effects while preventing graft rejection.

In the present study, a better control of arterial blood pressure was achieved in the group of patients treated with MSCs and CNI discontinuation as compared with the control group. This was accompanied by a significant reduction in LVM index and in the prevalence of LV hypertrophy at 24 weeks after transplantation without an increased rejection rate. 18 Additionally, MSC therapy seemed to prevent the progressive deterioration of LV diastolic function, as assessed by changes in mitral deceleration time and tricuspid regurgitant jet velocity. The regression of LV hypertrophy observed in the MSC group was the result of the decrease in LV thickness, mostly of the posterior wall, whereas there were no significant changes in the LV end-diastolic diameter.

Patients in the MSC group showed a higher eGFR at baseline in comparison with controls and had a reduction of eGFR during the study period of 24 weeks. On the other hand, a post hoc analysis of the TRITON study 18 demonstrated that renal function remains stable in the MSC group up to 5 years, whereas it gradually declined in the control group. Notably, the association between changes in LVM index and treatment group remained statistically significant after correcting for baseline clinical variables, including eGFR values.

The achievement of better blood pressure control in the MSC group may, at least partially, explain the more favorable LV remodeling, in comparison with the control group. Nevertheless, whether a direct antiremodeling action of MSCs or CNI withdrawal contributed to the regression of LV hypertrophy remains to be ascertained. Studies conducted in animal models of surgically induced renovascular hypertension showed that MSCs are effective in reducing LV hypertrophy and myocardial fibrosis. 36, 37 Besides their immunosuppressive and anti-inflammatory properties, MSCs could exert an antifibrotic action through several mechanisms, such as improving the myocardial regional blood flow through the upregulation of vascular endothelial growth factor, 38, 39 downregulating the myocardial expression of angiotensin II receptor type 1, and stimulating the secretion of antifibrotic cytokines such as adrenomedullin and metalloproteinases. 40, 41 Moreover, preclinical and clinical studies showed that the intracoronary or intramyocardial administration of MSCs may exert reparative capacities of the myocardium after an ischemic injury. 10 MSCs have been suggested to stimulate angiogenesis and myocardial regeneration through the paracrine activation of resident stem cells in the myocardium. 42 However, clinical trials that tested the use of MSCs in patients with ischemic heart failure have not shown consistent outcome benefits. 10 Therefore, the beneficial effects of MSC therapy in cardiovascular disease needs to be further clarified by larger randomized controlled studies.

On the other hand, there are conflicting data about the effect of CNIs on cardiac hypertrophy. In experimental models, calcineurin inhibition seemed to prevent the development of LV hypertrophy, [43] [44] [45] although other studies failed to confirm these data. 46 Moreover, a recent study in recipients of cardiac transplantation reported that the combination of low-dose tacrolimus and everolimus, compared with standard-dose tacrolimus, attenuates LV hypertrophy, with a reduction in myocardial fibrosis measured on late gadoliniumenhanced magnetic resonance and improvement in myocardial strain at 1 year after transplantation. 47 Of note, among patients treated with a standard dose of tacrolimus, there was an increase in LV hypertrophy and fibrosis, despite no changes in blood pressure, suggesting a direct adverse remodeling effect of CNIs. 47 Additionally, a strategy of late CNI withdrawal has been associated with prevention of progressive deterioration of LV diastolic function at 2 years after renal transplantation, but without relevant changes in LVM index. 48 However, most of the patients enrolled in the study did not have LV hypertrophy at the time of the randomization, 48 thus challenging the observation of any significant variations in LVM index.

Finally, it is important to note that the proportion of patients using an ACE-I/ARB at 4 weeks after transplantation was higher in the MSC group than in the control group. The treatment with ACE-I has been previously associated with regression of LV hypertrophy in renal transplant recipients. 49 Nevertheless, the association between reduction of LVM index and MSC therapy remained significant after correcting for the use of an ACE-I/ARB at baseline.

The present study was conducted in a single center, with a small-sized population and a short follow-up period. Therefore, our results need to be confirmed in larger trials, with long-term follow-up. Moreover, this study was not designed to discriminate between the effects of MSC therapy and CNI withdrawal on the blood pressure or the myocardium itself or both. The assessment of myocardial fibrosis with cardiac magnetic resonance would have strengthened our results. However, this goal was beyond the aim of the present study. More generally, the open-label design of the TRITON trial, required by the procedure of bone marrow aspiration and SUPPLEMENTAL MATERIAL
