Atrial arrhythmias following CAR-chimeric antigen receptor T-cell therapy: Incidence, risk factors and biomarker profile. Br J Haematol 2024. [PMID: 38735683 DOI: 10.1111/bjh.19497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Accepted: 04/18/2024] [Indexed: 05/14/2024]
Abstract
Recent reports have raised concerns about the association of chimeric antigen receptor T cell (CAR-T) with non-negligible cardiotoxicity, particularly atrial arrhythmias. First, we conducted a pharmacovigilance study to assess the reporting of atrial arrhythmias following CD19-directed CAR-T. Subsequently, to determine the incidence, risk factors and outcomes of atrial arrhythmias post-CAR-T, we compiled a retrospective single-centre cohort of non-Hodgkin lymphoma patients. Only commercial CAR-T products were considered. Atrial arrhythmias were nearly fourfold more likely to be reported after CAR-T therapy compared to all other cancer patients in the FAERS (adjusted ROR = 3.76 [95% CI 2.67-5.29]). Of the 236 patients in our institutional cohort, 23 (10%) developed atrial arrhythmias post-CAR-T, including 12 de novo arrhythmias, with most (83%) requiring medical intervention. Atrial arrhythmias frequently co-occurred with cytokine release syndrome and were associated with higher post-CAR-T infusion peak levels of IL-10, TNF-alpha and LDH, and lower trough levels of fibrinogen. In a multivariable analysis, risk factors for atrial arrhythmia were history of atrial arrhythmia (OR = 6.80 [2.39-19.6]) and using CAR-T product with a CD28-costimulatory domain (OR = 5.17 [1.72-18.6]). Atrial arrhythmias following CD19-CAR-T therapy are prevalent and associated with elevated inflammatory biomarkers, a history of atrial arrhythmia and the use of a CAR-T product with a CD28 costimulatory domain.

Atorvastatin for Anthracycline-Associated Cardiac Dysfunction: The STOP-CA Randomized Clinical Trial. JAMA 2023; 330:528-536. [PMID: 37552303 PMCID: PMC10410476 DOI: 10.1001/jama.2023.11887] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 06/12/2023] [Indexed: 08/09/2023]
Abstract
Importance Anthracyclines treat a broad range of cancers. Basic and retrospective clinical data have suggested that use of atorvastatin may be associated with a reduction in cardiac dysfunction due to anthracycline use. Objective To test whether atorvastatin is associated with a reduction in the proportion of patients with lymphoma receiving anthracyclines who develop cardiac dysfunction. Design, Setting, and Participants Double-blind randomized clinical trial conducted at 9 academic medical centers in the US and Canada among 300 patients with lymphoma who were scheduled to receive anthracycline-based chemotherapy. Enrollment occurred between January 25, 2017, and September 10, 2021, with final follow-up on October 10, 2022. Interventions Participants were randomized to receive atorvastatin, 40 mg/d (n = 150), or placebo (n = 150) for 12 months. Main Outcomes and Measures The primary outcome was the proportion of participants with an absolute decline in left ventricular ejection fraction (LVEF) of ≥10% from prior to chemotherapy to a final value of <55% over 12 months. A secondary outcome was the proportion of participants with an absolute decline in LVEF of ≥5% from prior to chemotherapy to a final value of <55% over 12 months. Results Of the 300 participants randomized (mean age, 50 [SD, 17] years; 142 women [47%]), 286 (95%) completed the trial. Among the entire cohort, the baseline mean LVEF was 63% (SD, 4.6%) and the follow-up LVEF was 58% (SD, 5.7%). Study drug adherence was noted in 91% of participants. At 12-month follow-up, 46 (15%) had a decline in LVEF of 10% or greater from prior to chemotherapy to a final value of less than 55%. The incidence of the primary end point was 9% (13/150) in the atorvastatin group and 22% (33/150) in the placebo group (P = .002). The odds of a 10% or greater decline in LVEF to a final value of less than 55% after anthracycline treatment was almost 3 times greater for participants randomized to placebo compared with those randomized to atorvastatin (odds ratio, 2.9; 95% CI, 1.4-6.4). Compared with placebo, atorvastatin also reduced the incidence of the secondary end point (13% vs 29%; P = .001). There were 13 adjudicated heart failure events (4%) over 24 months of follow-up. There was no difference in the rates of incident heart failure between study groups (3% with atorvastatin, 6% with placebo; P = .26). The number of serious related adverse events was low and similar between groups. Conclusions and Relevance Among patients with lymphoma treated with anthracycline-based chemotherapy, atorvastatin reduced the incidence of cardiac dysfunction. This finding may support the use of atorvastatin in patients with lymphoma at high risk of cardiac dysfunction due to anthracycline use. Trial Registration ClinicalTrials.gov Identifier: NCT02943590.

Coronary vasospasm during infusion of CD-19 directed chimeric antigen receptor T-cell therapy: a case report. Eur Heart J Case Rep 2023; 7:ytad342. [PMID: 37547374 PMCID: PMC10398419 DOI: 10.1093/ehjcr/ytad342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 01/25/2023] [Accepted: 07/19/2023] [Indexed: 08/08/2023]
Abstract
Background Cardiovascular events have been reported to occur in one in five patients receiving chimeric antigen receptor T-cell (CAR-T) therapy. Commonly reported effects including cardiomyopathy, heart failure, myocardial infarction (MI), and arrhythmia. Here, we present a novel case of a patient who developed acute ST segment elevations during CAR-T cell infusion. Case summary A 76-year-old man with diffuse large B cell lymphoma was admitted for an investigational CD-19 directed, autologous CAR-T cell therapy. Less than 5 min into the CAR-T cell infusion, he developed severe chest pain, dyspnea, flushing, hypotension, and tachycardia. Electrocardiogram (EKG) showed inferior ST elevations and reciprocal lateral ST depressions. Emergent coronary angiography revealed mild non-obstructive coronary disease. ST segment changes and patient symptoms resolved after catheterization. Discussion Given the complete resolution of symptoms and EKG abnormalities in the context of non-obstructive coronary artery disease, this clinical presentation was thought to be most consistent with ST elevation MI due to coronary vasospasm. The mechanism of this vasospasm is as yet not understood and may be related to an anaphylactic reaction or a cardiotoxicity related to the cell therapy agent. As the use of CAR-T therapy continues to expand, there is a need to further characterize the full spectrum of its cardiotoxic effects.

Biomarkers and cardiovascular outcomes in chimeric antigen receptor T-cell therapy recipients. Eur Heart J 2023; 44:2029-2042. [PMID: 36939851 PMCID: PMC10256191 DOI: 10.1093/eurheartj/ehad117] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 02/10/2023] [Accepted: 02/16/2023] [Indexed: 03/21/2023] Open
Abstract
AIMS Chimeric antigen receptor T-cell therapy (CAR-T) harnesses a patient's immune system to target cancer. There are sparse existing data characterizing death outcomes after CAR-T-related cardiotoxicity. This study examines the association between CAR-T-related severe cardiovascular events (SCE) and mortality. METHODS AND RESULTS From a multi-centre registry of 202 patients receiving anti-CD19 CAR-T, covariates including standard baseline cardiovascular and cancer parameters and biomarkers were collected. Severe cardiovascular events were defined as a composite of heart failure, cardiogenic shock, or myocardial infarction. Thirty-three patients experienced SCE, and 108 patients died during a median follow-up of 297 (interquartile range 104-647) days. Those that did and did not die after CAR-T were similar in age, sex, and prior anthracycline use. Those who died had higher peak interleukin (IL)-6 and ferritin levels after CAR-T infusion, and those who experienced SCE had higher peak IL-6, C-reactive protein (CRP), ferritin, and troponin levels. The day-100 and 1-year Kaplan-Meier overall mortality estimates were 18% and 43%, respectively, while the non-relapse mortality (NRM) cumulative incidence rates were 3.5% and 6.7%, respectively. In a Cox model, SCE occurrence following CAR-T was independently associated with increased overall mortality risk [hazard ratio (HR) 2.8, 95% confidence interval (CI) 1.6-4.7] after adjusting for age, cancer type and burden, anthracycline use, cytokine release syndrome grade ≥ 2, pre-existing heart failure, hypertension, and African American ancestry; SCEs were independently associated with increased NRM (HR 3.5, 95% CI 1.4-8.8) after adjusting for cancer burden. CONCLUSION Chimeric antigen receptor T-cell therapy recipients who experience SCE have higher overall mortality and NRM and higher peak levels of IL-6, CRP, ferritin, and troponin.

Suboptimal Cardiology Follow-Up Among Patients With and Without Cancer Hospitalized for Heart Failure. Am J Cardiol 2023; 196:79-86. [PMID: 37019746 DOI: 10.1016/j.amjcard.2023.02.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 02/19/2023] [Accepted: 02/25/2023] [Indexed: 04/07/2023]
Abstract
Many patients hospitalized for heart failure (HF) do not receive recommended follow-up cardiology care, and non-White patients are less likely to receive follow-up than White patients. Poor HF management may be particularly problematic in patients with cancer because cardiovascular co-morbidity can delay cancer treatments. Therefore, we sought to describe outpatient cardiology care patterns in patients with cancer hospitalized for HF and to determine if receipt of follow-up varied by race/ethnicity. SEER (Surveillance, Epidemiology, and End Results) data from 2007 to 2013 linked to Medicare claims from 2006 to 2014 were used. We included patients aged 66+ years with breast, prostate, or colorectal cancer, and preexisting HF. Patients with cancer were matched to patients in a noncancer cohort that included individuals with HF and no cancer. The primary outcome was receipt of an outpatient, face-to-face cardiologist visit within 30 days of HF hospitalization. We compared follow-up rates between cancer and noncancer cohorts, and stratified analyses by race/ethnicity. A total of 2,356 patients with cancer and 2,362 patients without cancer were included. Overall, 43% of patients with cancer and 42% of patients without cancer received cardiologist follow-up (p = 0.30). After multivariable adjustment, White patients were 15% more likely to receive cardiology follow-up than Black patients (95% confidence interval [CI] 1.02 to 1.30). Black patients with cancer were 41% (95% CI 1.11 to 1.78) and Asian patients with cancer were 66% (95% CI 1.11 to 2.49) more likely to visit a cardiologist than their noncancer counterparts. In conclusion, less than half of patients with cancer hospitalized for HF received recommended follow-up with a cardiologist, and significant race-related differences in cardiology follow-up exist. Future studies should investigate the reasons for these differences.

Global Circumferential and Radial Strain Among Patients With Immune Checkpoint Inhibitor Myocarditis. JACC Cardiovasc Imaging 2022; 15:1883-1896. [PMID: 36357131 PMCID: PMC10334352 DOI: 10.1016/j.jcmg.2022.06.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 05/25/2022] [Accepted: 06/22/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Global circumferential strain (GCS) and global radial strain (GRS) are reduced with cytotoxic chemotherapy. There are limited data on the effect of immune checkpoint inhibitor (ICI) myocarditis on GCS and GRS. OBJECTIVES This study aimed to detail the role of GCS and GRS in ICI myocarditis. METHODS In this retrospective study, GCS and GRS from 75 cases of patients with ICI myocarditis and 50 ICI-treated patients without myocarditis (controls) were compared. Pre-ICI GCS and GRS were available for 12 cases and 50 controls. Measurements were performed in a core laboratory blinded to group and time. Major adverse cardiovascular events (MACEs) were defined as a composite of cardiogenic shock, cardiac arrest, complete heart block, and cardiac death. RESULTS Cases and controls were similar in age (66 ± 15 years vs 63 ± 12 years; P = 0.20), sex (male: 73% vs 61%; P = 0.20) and cancer type (P = 0.08). Pre-ICI GCS and GRS were also similar (GCS: 22.6% ± 3.4% vs 23.5% ± 3.8%; P = 0.14; GRS: 45.5% ± 6.2% vs 43.6% ± 8.8%; P = 0.24). Overall, 56% (n = 42) of patients with myocarditis presented with preserved left ventricular ejection fraction (LVEF). GCS and GRS were lower in myocarditis compared with on-ICI controls (GCS: 17.5% ± 4.2% vs 23.6% ± 3.0%; P < 0.001; GRS: 28.6% ± 6.7% vs 47.0% ± 7.4%; P < 0.001). Over a median follow-up of 30 days, 28 cardiovascular events occurred. A GCS (HR: 4.9 [95% CI: 1.6-15.0]; P = 0.005) and GRS (HR: 3.9 [95% CI: 1.4-10.8]; P = 0.008) below the median was associated with an increased event rate. In receiver-operating characteristic (ROC) curves, GCS (AUC: 0.80 [95% CI: 0.70-0.91]) and GRS (AUC: 0.76 [95% CI: 0.64-0.88]) showed better performance than cardiac troponin T (cTnT) (AUC: 0.70 [95% CI: 0.58-0.82]), LVEF (AUC: 0.69 [95% CI: 0.56-0.81]), and age (AUC: 0.54 [95% CI: 0.40-0.68]). Net reclassification index and integrated discrimination improvement demonstrated incremental prognostic utility of GRS over LVEF (P = 0.04) and GCS over cTnT (P = 0.002). CONCLUSIONS GCS and GRS are lower in ICI myocarditis, and the magnitude of reduction has prognostic significance.

Incidence, clinical associations and outcomes of intrathoracic complications with and without ARDS in COVID-19 pneumonia. Clin Imaging 2022; 85:106-114. [PMID: 35278869 PMCID: PMC8895681 DOI: 10.1016/j.clinimag.2022.02.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 12/06/2021] [Accepted: 02/28/2022] [Indexed: 01/08/2023]
Abstract
PURPOSE To determine the incidence and clinical predictors of intrathoracic complications in COVID-19 patients, and the association with outcomes. METHODS In this retrospective cross-sectional study, we included 976 patients (age 61 ± 17 years, 62% male) who tested positive for SARS-CoV-2 between March 3-April 4, 2020 and underwent chest imaging. 3836 radiographs from 976 patients and 105 CTs from 88 patients were reviewed for intrathoracic complications, including pneumothorax, pneumomediastinum, pneumopericardium, lobar collapse, pleural effusion, and pneumatocele formation. RESULTS There was a high rate of intrathoracic complications (197/976, 20%). Pleural effusion was the most common complication (168/976, 17%). Pneumothorax (30/976, 3%) and pneumatoceles (9/88, 10%) were also frequent. History of hypertension and high initial CXR severity score were independent risk factors for complications. Patients with any intrathoracic complication during admission had an over 11-fold risk of ICU admission (adjusted odds ratio [aOR] 11.2, p < 0.0001) and intubation (aOR 12.4, p < 0.0001), over 50% reduction in successful extubation (aOR 0.49, p = 0.02) and longer length of stay (median 13 versus 5 days, p < 0.0001). There was no difference in overall survival between patients with and without any complication (log-rank p = 0.94). CONCLUSION In COVID-19 patients who underwent chest imaging, 1 in 5 patients have an intrathoracic complication, which are associated with higher level of care and prolonged hospital stay. Hypertension history and high CXR severity score confer an increased risk of complication. SUMMARY Intrathoracic complications in COVID-19 are common and are predictive of ICU admission, need for intubation, less successful extubation, and longer length of stay but are not predictive of mortality.

Abstract
651 Background: With recent improvements in survival of cancer patients and emphasis on high-value care at end-of-life, the management of cardiovascular disease in patients with cancer is increasingly important. To our knowledge, there is no current US data examining how the presence and extent of cancer influence cardiologists’ decision-making for common cardiovascular conditions. Methods: An anonymous online vignette-based survey of cardiologists was conducted at five US institutions investigating how the extent of gastrointestinal and thoracic malignancies (prior/localized, metastatic) would influence treatment recommendation for atrial fibrillation (AF), aortic stenosis (AS), unstable angina (UA) and obstructive coronary artery disease (CAD). Results: Thirty-three percent (86/259) of cardiologists completed the survey between September and November 2019. Participants were 67% male, 51% below age 40, and 58% had five or more years of clinical experience. Majority of cardiologists practiced at teaching hospitals (72%) and were non-interventional (63%). Cardiologists were more likely to recommend procedural interventions in patients with localized cancer than with metastatic disease: AF (LAAO: 20% vs 8%), AS (AVR: 83% vs 11%), UA (LHC: 70% vs 27%) and obstructive CAD (PCI: 81% vs 38%) (Table). In patients with metastatic cancer, most cardiologists sought an oncology (82%) or a palliative care (69%) consult. Conclusions: Cardiologists were less likely to recommend invasive cardiovascular therapies to patients with metastatic cancer. This preference pattern likely reflects the influence of comorbidities and quality of life expectation on cardiologists’ treatment recommendations but may also be related to the stigma of advanced cancer. Better communication between cardiologists and oncologists is necessary to a personalized care of patients with cancer and cardiovascular disease that would maximize treatment benefit with least morbidity.[Table: see text]

Abstract
BACKGROUND Pivotal trials of chimeric antigen receptor T-cell (CAR-T) have identified common toxicities but may have been underpowered to detect cardiovascular and pulmonary adverse events (CPAEs). OBJECTIVES This study sought to investigate CPAEs associated with commercial CD19-directed CAR-T therapy. METHODS In this retrospective, pharmacovigilance study, the authors used the Food and Drug Administration adverse event reporting system to identify CPAEs associated with axicabtagene-ciloleucel and tisagenlecleucel. The authors evaluated disproportionate reporting by the reporting odds ratio (ROR) and the lower bound of the information component 95% credibility interval (IC025 >0 is deemed significant). Significant associations were further adjusted to age and sex (adj.ROR). RESULTS The authors identified CAR-T reports of 2,657 patients, including 546 CPAEs (20.5%). CPAEs overlapped with cytokine release syndrome in 68.3% (373 of 546) of the reports. Compared with the full database, CAR-T was associated with overreporting of tachyarrhythmias (n = 74 [2.8%], adj.ROR = 2.78 [95% CI: 2.21-3.51]), cardiomyopathy (n = 69 [2.6%], adj.ROR = 3.51 [2.42-5.09]), pleural disorders (n = 46 [1.7%], adj.ROR = 3.91 [2.92-5.23]), and pericardial diseases (n = 11 [0.4%], adj.ROR = 2.26 [1.25-4.09], all IC025 >0). Venous thromboembolic events (VTEs) were associated only with axicabtagene-ciloleucel therapy (n = 28 [1.6%], adj.ROR = 1.80 [1.24-2.62], IC025 >0). Atrial fibrillation (n = 55) was the leading tachyarrhythmia, followed by ventricular arrhythmias (n = 14). Tachyarrhythmias and VTEs were reported more often following axicabtagene-ciloleucel than tisagenlecleucel in an age- and sex-adjusted model (adj.ROR = 1.82 [1.04-3.18] and adj.ROR = 2.86 [1.18-6.93], respectively). Finally, the fatality rate of CPAEs was 30.9%. CONCLUSIONS In this largest post-marketing study to date, the authors identified an association between CAR-T and various CPAEs, including tachyarrhythmias, cardiomyopathy, pericardial and pleural disorders, and VTEs. These findings should be considered in the multidisciplinary assessment for and monitoring of CAR-T therapy recipients.

Abstract
Abstract
Background
Immune checkpoint inhibitor (ICI)-associated myocarditis is associated with a markedly increased risk of morbidity and mortality. The occurrence of ventricular arrhythmias (VA) in patients with ICI-associated myocarditis has not been well characterized.
Purpose
The aim of this study was to determine the characteristics and risk factors for severe VA in patients with ICI myocarditis.
Methods
The cohort consisted of 202 patients with ICI myocarditis. Ventricular arrhythmias were defined as a composite of sustained ventricular tachycardia and ventricular fibrillation. We used a multivariable logistic regression model to test the association between clinical variables and the development of VA.
Results
From a cohort of 202 patients with ICI myocarditis (67±13 years, 35% female, 60% hypertension, 23% diabetes mellitus), 41 (20.3%) developed VA, of which, 33 had VT and 8 had VF. The median time from admission to VF was 144 hours and to VT was 72 hours. A VA occurred in 17.5% of patients with a normal LVEF, and 25% of patients with reduced LVEF. On univariate analysis, a QRS duration >110ms (OR 2.88, 95% CI 1.40 to 6.16, P=0.005) and a QTc duration >470ms were associated with an increased probability of VA (OR 2.58, 95% CI 1.23, 5.41, P=0.012). The association remained significant after adjustment for age and gender. Additionally, a longer time from admission to initiation of corticosteroids was associated with a higher probability of VA (OR 1.06, 95% CI 1.01 to 1.13, P=0.027). The association between the time from admission to administration of corticosteroids and probability of VA remained significant after adjustment for age, gender, and LVEF on admission (OR, 1.06, 95% CI 1.00, 1.13, P=0.037) where each 6-hour delay in the initiation of corticosteroids was associated with a 4% increase in the risk for VA.
Conclusions
Ventricular arrhythmias are common in the setting of ICI myocarditis and are observed in patients presenting with both a preserved and a reduced LVEF. Wider QRS and longer QT at presentation and longer time from admission to initiation of corticosteroids were associated with an increased risk of VA.

Abstract
Background Myocarditis is a highly morbid complication of immune checkpoint inhibitor (ICI) use that remains inadequately characterized. The QRS duration and the QTc interval are standardized electrocardiographic measures that are prolonged in other cardiac conditions; however, there are no data on their utility in ICI myocarditis. Methods From an international registry, ECG parameters were compared between 140 myocarditis cases and 179 controls across multiple time points (pre-ICI, on ICI prior to myocarditis, and at the time of myocarditis). The association between ECG values and major adverse cardiac events (MACE) was also tested. Results Both the QRS duration and QTc interval were similar between cases and controls prior to myocarditis. When compared with controls on an ICI (93±19 ms) or to baseline prior to myocarditis (97±19 ms), the QRS duration prolonged with myocarditis (110±22 ms, p<0.001 and p=0.009, respectively). In contrast, the QTc interval at the time of myocarditis (435±39 ms) was not increased compared with pre-myocarditis baseline (422±27 ms, p=0.42). A prolonged QRS duration conferred an increased risk of subsequent MACE (HR 3.28, 95% CI 1.98 to 5.62, p<0.001). After adjustment, each 10 ms increase in the QRS duration conferred a 1.3-fold increase in the odds of MACE (95% CI 1.07 to 1.61, p=0.011). Conversely, there was no association between the QTc interval and MACE among men (HR 1.33, 95% CI 0.70 to 2.53, p=0.38) or women (HR 1.48, 95% CI 0.61 to 3.58, p=0.39). Conclusions The QRS duration is increased in ICI myocarditis and is associated with increased MACE risk. Use of this widely available ECG parameter may aid in ICI myocarditis diagnosis and risk-stratification.

Myocardial T1 and T2 Mapping by Magnetic Resonance in Patients With Immune Checkpoint Inhibitor-Associated Myocarditis. J Am Coll Cardiol 2021; 77:1503-1516. [PMID: 33766256 DOI: 10.1016/j.jacc.2021.01.050] [Citation(s) in RCA: 91] [Impact Index Per Article: 30.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/25/2021] [Accepted: 01/28/2021] [Indexed: 01/06/2023]
Abstract
BACKGROUND Myocarditis is a potentially fatal complication of immune checkpoint inhibitor (ICI) therapy. Data on the utility of cardiovascular magnetic resonance (CMR) T1 and T2 mapping in ICI myocarditis are limited. OBJECTIVES This study sought to assess the value of CMR T1 and T2 mapping in patients with ICI myocarditis. METHODS In this retrospective study from an international registry of patients with ICI myocarditis, clinical and CMR findings (including T1 and T2 maps) were collected. Abnormal T1 and T2 were defined as 2 SD above site (vendor/field strength specific) reference values and a z-score was calculated for each patient. Major adverse cardiovascular events (MACE) were a composite of cardiovascular death, cardiogenic shock, cardiac arrest, and complete heart block. RESULTS Of 136 patients with ICI myocarditis with a CMR, 86 (63%) had T1 maps and 79 (58%) also had T2 maps. Among the 86 patients (66.3 ± 13.1 years of age), 36 (41.9%) had a left ventricular ejection fraction <55%. Across all patients, mean z-scores for T1 and T2 values were 2.9 ± 1.9 (p < 0.001) and 2.2 ± 2.1 (p < 0.001), respectively. On Siemens 1.5-T scanner (n = 67), native T1 (1,079.0 ± 55.5 ms vs. 1,000.3 ± 22.1 ms; p < 0.001) and T2 (56.2 ± 4.9 ms vs. 49.8 ± 2.2 ms; p < 0.001) values were elevated compared with reference values. Abnormal T1 and T2 values were seen in 78% and 43% of the patients, respectively. Applying the modified Lake Louise Criteria, 95% met the nonischemic myocardial injury criteria and 53% met the myocardial edema criteria. Native T1 values had excellent discriminatory value for subsequent MACE, with an area under the curve of 0.91 (95% confidence interval: 0.84 to 0.98). Native T1 values (for every 1-unit increase in z-score, hazard ratio: 1.44; 95% confidence interval: 1.12 to 1.84; p = 0.004) but not T2 values were independently associated with subsequent MACE. CONCLUSIONS The use of T1 mapping and application of the modified Lake Louise Criteria provides important diagnostic value, and T1 mapping provides prognostic value in patients with ICI myocarditis.

Abstract
CONTEXT.— Cardiac complications of immune checkpoint inhibitor therapy are rare, but reports of myocarditis are increasing. The findings have been described in case reports as lymphocytic myocarditis, but its histopathology is underreported. OBJECTIVE.— To review the histology of myocardial biopsy-proven cases of immune checkpoint-associated myocarditis and provide immunohistochemical characterization of the inflammatory infiltrate. DESIGN.— We have encountered 6 patients with biopsy-proven myocarditis in conjunction with therapy using anti-programmed death receptor-1 (PD-1)/programmed death ligand-1 (PD-L1) agents with and without cytotoxic T-lymphocyte associated protein 4 (CTLA-4) inhibitors and characterized the histopathology and immune cell profile. RESULTS.— The myocarditis was multifocal/diffuse and characterized by a predominant CD163-positive histiocytic infiltrate, with an associated CD8+ and PD-1+ T-lymphocytic infiltrate, some of which were granzyme B positive. Cardiac myocytes showed immunoreactivity for PD-L1 in areas of injury, confirmed using 2 different anti-PD-L1 clones. Four of 6 patients recovered from their cardiac injury. One patient had residual tachycardia-bradycardia syndrome and 1 patient expired. CONCLUSIONS.— The diffuse lymphohistiocytic myocarditis associated with this therapy is relatively distinctive, and this diagnosis is strongly suggested based on the histopathologic findings in the correct clinical setting.

Abstract
Background Coronavirus disease 2019 (COVID-19) affects vulnerable populations (VP) adversely. Purpose To evaluate overall imaging utilization in vulnerable subgroups (elderly, racial/ethnic minorities, socioeconomic status [SES] disadvantage) and determine if a particular subgroup has worse outcomes from COVID-19. Materials/Methods Of 4110 patients who underwent COVID-19 testing from March 3-April 4, 2020 at NewYork-Presbyterian Hospital (NYP) health system, we included 1121 COVID-19 positive adults (mean age 59±18 years, 59% male) from two academic hospitals and evaluated imaging utilization rates and outcomes, including mortality. Results Of 897 (80%) VP, there were 465 (41%) elderly, 380 (34%) racial/ethnic minorities, and 479 (43%) SES disadvantage patients. Imaging was performed in 88% of patients and mostly portable/bedside studies, with 87% of patients receiving chest radiographs. There were 83% hospital admissions, 25% ICU admissions, 23% intubations, and 13% deaths. Elderly patients had greater imaging utilization, hospitalizations, ICU/intubation requirement, longer hospital stays, and >4-fold increase in mortality compared to non-elderlies (adjusted hazard ratio[aHR] 4.79, p<0.001). Self-reported minorities had fewer ICU admissions (p=0.03) and reduced hazard for mortality (aHR 0.53, p=0.004; complete case analysis: aHR 0.39, p<0.001 excluding "not reported"; sensitivity analysis: aHR 0.61, p=0.005 "not reported" classified as minorities) with similar imaging utilization, compared to non-minorities. SES disadvantage patients had similar imaging utilization and outcomes as compared to their counterparts. Conclusions In a predominantly hospitalized New York City cohort, elderly patients are at highest mortality risk. Racial/ethnic minorities and SES disadvantage patients fare better or similarly to their counterparts, highlighting the critical role of access to inpatient medical care during the COVID-19 pandemic.

Abstract
AIMS The prognostic importance of post-diagnosis assessment of cardiorespiratory fitness (CRF) in cancer patients is not well established. We sought to examine the association between CRF and mortality in cancer patients. METHODS AND RESULTS This was a single-centre cohort analysis of 1632 patients (58% male; 64 ± 12 years) with adult-onset cancer who were clinically referred for exercise treadmill testing a median of 7 [interquartile range (IQR): 3-12] years after primary diagnosis. Cardiorespiratory fitness was defined as peak metabolic equivalents (METs) achieved during standard Bruce protocol and categorized by tertiles. The association between CRF and all-cause and cause-specific mortality was assessed using multivariable Cox proportional hazard models adjusting for important covariates. Median follow-up was 4.6 (IQR: 2.6-7.0) years; a total of 411 deaths (229, 50, and 132 all-cause, cardiovascular (CV), and cancer related, respectively) occurred during this period. Compared with low CRF (range: 1.9-7.6 METs), the adjusted hazard ratio (HR) for all-cause mortality was 0.38 [95% confidence interval (CI): 0.28-0.52] for intermediate CRF (range: 7.7-10.6 METs) and 0.17 (95% CI: 0.11-0.27) for high CRF (range: 10.7-22.0 METs). The corresponding HRs were 0.40 (95% CI: 0.19-0.86) and 0.41 (95% CI: 0.16-1.05) for CV mortality and 0.40 (95% CI: 0.26-0.60) and 0.16 (95% CI: 0.09-0.28) for cancer mortality, respectively. The adjusted risk of all-cause, CV, and cancer mortality decreased by 26%, 14%, and 25%, respectively with each one MET increment in CRF. CONCLUSION Cardiorespiratory fitness is a strong, independent predictor of all-cause, CV, and cancer mortality, even after adjustment for important clinical covariates in patients with certain cancers.

Abstract
BACKGROUND There is a need for improved methods for detection and risk stratification of myocarditis associated with immune checkpoint inhibitors (ICIs). Global longitudinal strain (GLS) is a sensitive marker of cardiac toxicity among patients receiving standard chemotherapy. There are no data on the use of GLS in ICI myocarditis. OBJECTIVES This study sought to evaluate the role of GLS and assess its association with cardiac events among patients with ICI myocarditis. METHODS This study retrospectively compared echocardiographic GLS by speckle tracking at presentation with ICI myocarditis (cases, n = 101) to that from patients receiving an ICI who did not develop myocarditis (control subjects, n = 92). Where available, GLS was also measured pre-ICI in both groups. Major adverse cardiac events (MACE) were defined as a composite of cardiogenic shock, arrest, complete heart block, and cardiac death. RESULTS Cases and control subjects were similar in age, sex, and cancer type. At presentation with myocarditis, 61 cases (60%) had a normal ejection fraction (EF). Pre-ICI, GLS was similar between cases and control subjects (20.3 ± 2.6% vs. 20.6 ± 2.0%; p = 0.60). There was no change in GLS among control subjects on an ICI without myocarditis (pre-ICI vs. on ICI, 20.6 ± 2.0% vs. 20.5 ± 1.9%; p = 0.41); in contrast, among cases, GLS decreased to 14.1 ± 2.8% (p < 0.001). The GLS at presentation with myocarditis was lower among cases presenting with either a reduced (12.3 ± 2.7%) or preserved EF (15.3 ± 2.0%; p < 0.001). Over a median follow-up of 162 days, 51 (51%) experienced MACE. The risk of MACE was higher with a lower GLS among patients with either a reduced or preserved EF. After adjustment for EF, each percent reduction in GLS was associated with a 1.5-fold increase in MACE among patients with a reduced EF (hazard ratio: 1.5; 95% confidence interval: 1.2 to 1.8) and a 4.4-fold increase with a preserved EF (hazard ratio: 4.4; 95% confidence interval: 2.4 to 7.8). CONCLUSIONS GLS decreases with ICI myocarditis and, compared with control subjects, was lower among cases presenting with either a preserved or reduced EF. Lower GLS was strongly associated with MACE in ICI myocarditis presenting with either a preserved or reduced EF.

Abstract
AIMS Myocarditis is a potentially fatal complication of immune checkpoint inhibitors (ICI). Sparse data exist on the use of cardiovascular magnetic resonance (CMR) in ICI-associated myocarditis. In this study, the CMR characteristics and the association between CMR features and cardiovascular events among patients with ICI-associated myocarditis are presented. METHODS AND RESULTS From an international registry of patients with ICI-associated myocarditis, clinical, CMR, and histopathological findings were collected. Major adverse cardiovascular events (MACE) were a composite of cardiovascular death, cardiogenic shock, cardiac arrest, and complete heart block. In 103 patients diagnosed with ICI-associated myocarditis who had a CMR, the mean left ventricular ejection fraction (LVEF) was 50%, and 61% of patients had an LVEF ≥50%. Late gadolinium enhancement (LGE) was present in 48% overall, 55% of the reduced EF, and 43% of the preserved EF cohort. Elevated T2-weighted short tau inversion recovery (STIR) was present in 28% overall, 30% of the reduced EF, and 26% of the preserved EF cohort. The presence of LGE increased from 21.6%, when CMR was performed within 4 days of admission to 72.0% when CMR was performed on Day 4 of admission or later. Fifty-six patients had cardiac pathology. Late gadolinium enhancement was present in 35% of patients with pathological fibrosis and elevated T2-weighted STIR signal was present in 26% with a lymphocytic infiltration. Forty-one patients (40%) had MACE over a follow-up time of 5 months. The presence of LGE, LGE pattern, or elevated T2-weighted STIR were not associated with MACE. CONCLUSION These data suggest caution in reliance on LGE or a qualitative T2-STIR-only approach for the exclusion of ICI-associated myocarditis.

Abstract
Left ventricular systolic dysfunction (LVSD) and overt heart failure are well known manifestations of chemotherapy-induced cardiotoxicity. The development of LVSD is clinically significant because it can impact the delivery of lifesaving chemotherapy and increase the risk of developing heart failure, compromising quality of life and survival years after cure of the cancer. Cancer treatment-related cardiomyopathy is most commonly associated with anthracyclines and trastuzumab. Several interventions have been identified to prevent cancer-induced cardiomyopathy. Anthracyclines is a major culprit, and prevention strategies with limiting cumulative dose, continuous infusion, dexrazoxane, and liposomal formulation have been shown to decrease the risk of cardiotoxicity.

Influenza vaccination and myocarditis among patients receiving immune checkpoint inhibitors. J Immunother Cancer 2019; 7:53.

Abstract
Background Influenza vaccination (FV) is recommended for patients with cancer. Recent data suggested that the administration of the FV was associated with an increase in immune-related adverse events (irAEs) among patients on immune checkpoint inhibitors (ICIs). Myocarditis is an uncommon but serious complication of ICIs and may also result from infection with influenza. There are no data testing the relationship between FV and the development of myocarditis on ICIs. Methods Patients on ICIs who developed myocarditis (n = 101) (cases) were compared to ICI-treated patients (n = 201) without myocarditis (controls). A patient was defined as having the FV if they were administered the FV from 6 months prior to start of ICI to anytime during ICI therapy. Alternate thresholds for FV status were also tested. The primary comparison of interest was the rate of FV between cases and controls. Patients with myocarditis were followed for major adverse cardiac events (MACE), defined as the composite of cardiogenic shock, cardiac arrest, hemodynamically significant complete heart block and cardiovascular death. Results The FV was administered to 25% of the myocarditis cases compared to 40% of the non-myocarditis ICI-treated controls (p = 0.01). Similar findings of lower rates of FV administration were noted among myocarditis cases when alternate thresholds were tested. Among the myocarditis cases, those who were vaccinated had 3-fold lower troponin levels when compared to unvaccinated cases (FV vs. No FV: 0.12 [0.02, 0.47] vs. 0.40 [0.11, 1.26] ng/ml, p = 0.02). Within myocarditis cases, those administered the FV also had a lower rate of other irAEs when compared to unvaccinated cases (36 vs. 55% p = 0.10) including lower rates of pneumonitis (12 vs. 36%, p = 0.03). During follow-up (175 [IQR 89, 363] days), 47% of myocarditis cases experienced a MACE. Myocarditis cases who received the FV were at a lower risk of cumulative MACE when compared to unvaccinated cases (24 vs. 59%, p = 0.002). Conclusion The rate of FV among ICI-related myocarditis cases was lower than controls on ICIs who did not develop myocarditis. In those who developed myocarditis related to an ICI, there was less myocardial injury and a lower risk of MACE among those who were administered the FV.

Abstract
Background Mechanisms underlying impaired exercise capacity and increased cardiovascular mortality observed in breast cancer (BC) patients remain unclear. The prevalence, functional, and prognostic significance of elevated resting heart rate (HR) and abnormal heart rate recovery (HRR) in breast cancer (BC) requires evaluation. Methods In a single‐center, retrospective, case‐control study of women referred for exercise treadmill testing (ETT), 448 BC patients (62.6 ± 10.0 years) were compared to 448 cancer‐free, age‐matched controls. Elevated resting HR was defined as HR ≥80 bpm at rest. Abnormal HRR at 1‐minute following exercise was defined as ≤12 bpm if active recovery or ≤18 bpm if passive recovery. Association of these parameters with exercise capacity and all‐cause mortality was evaluated. Results Elevated resting HR (23.7% vs 17.0%, P = 0.013) and abnormal HRR (25.9% vs 20.3%, P = 0.048) were more prevalent in BC cohort than controls. In adjusted analyses, BC patients with elevated resting HR (−0.9 METs (SE 0.3); P = 0.0003) or abnormal HRR (−1.3 METs (SE 0.3); P < 0.0001) had significant reductions in metabolic equivalents (METs) achieved during exercise. Elevated resting HR was not associated with mortality. There was a trend toward increased mortality in BC cohort with abnormal HRR (adjusted hazard ratio 2.06 (95% CI 0.95‐4.44, P = 0.07)). Conclusions Women across the BC survivorship continuum, referred for ETT, have an increased prevalence of elevated resting HR and abnormal HRR relative to cancer‐free, age‐matched female controls. These parameters were associated with decreased exercise capacity. Strategies to modulate these abnormalities may help improve functional capacity in this cohort.

Heart-lung interactions during mechanical ventilation: the basics. ANNALS OF TRANSLATIONAL MEDICINE 2018; 6:349.

Abstract
The hemodynamic effects of mechanical ventilation can be grouped into three clinically relevant concepts. First, since spontaneous ventilation is exercise. In patients increased work of breathing, initiation of mechanical ventilatory support may improve O2 delivery because the work of breathing is reduced. Second, changes in lung volume alter autonomic tone, pulmonary vascular resistance, and at high lung volumes compress the heart in the cardiac fossa similarly to cardiac tamponade. As lung volume increases so does the pressure difference between airway and pleural pressure. When this pressure difference exceeds pulmonary artery pressure, pulmonary vessels collapse as they pass form the pulmonary arteries into the alveolar space increasing pulmonary vascular resistance. Hyperinflation increases pulmonary vascular resistance impeding right ventricular ejection. Anything that over distends lung units will increase their vascular resistance, and if occurring globally throughout the lung, increase pulmonary vascular resistance. Decreases in end-expiratory lung volume cause alveolar collapse increases pulmonary vasomotor tone by the process of hypoxic pulmonary vasoconstriction. Recruitment maneuvers that restore alveolar oxygenation without over distention will reduce pulmonary artery pressure. Third, positive-pressure ventilation increases intrathoracic pressure. Since diaphragmatic descent increases intra-abdominal pressure, the decrease in the pressure gradient for venous return is less than would otherwise occur if the only change were an increase in right atrial pressure. However, in hypovolemic states, it can induce profound decreases in venous return. Increases in intrathoracic pressure decreases left ventricular afterload and will augment left ventricular ejection. In patients with hypervolemic heart failure, this afterload reducing effect can result in improved left ventricular ejection, increased cardiac output and reduced myocardial O2 demand. This brief review will focus primarily on mechanical ventilation and intrathoracic pressure as they affect right and left ventricular function and cardiac output.

Abstract
Background Fulminant myocarditis has been reported in patients treated with immune checkpoint inhibitors. We present the first described case of acute immune-mediated myocarditis and myositis associated with durvalumab plus tremelimumab combination therapy. The patient was undergoing treatment for advanced endometrial cancer. Case presentation A 75-year-old Caucasian female presented with difficulty ambulating due to neck protraction, imbalance, and increased shortness of breath with exertion 3 weeks after her first durvalumab and tremelimumab administration for advanced endometrial cancer. While the patient's initial laboratory data showed an acute transaminitis and elevated creatine phosphokinase (CPK), consistent with myositis, she developed complete heart block and ventricular dysfunction, with elevated troponins. Endomyocardial biopsy confirmed a diagnosis of immune-mediated myocarditis. She was treated with high-dose steroids and mycophenolate mofetil, which led to eventual native conduction and left ventricular ejection fraction recovery. Upon discharge, she was titrated off of steroids over 8 weeks and her mycophenolate was subsequently stopped. A follow-up computed tomography scan revealed progression of metastatic disease. The patient remains alive using supplemental oxygen 3 months after admission. Conclusions Durvalumab plus tremelimumab combination therapy can lead to fulminant immune-mediated myocarditis. This patient's myocarditis was amenable to treatment with high-dose intravenous steroids and mycophenolate. First description of myocarditis after durvalumab plus tremelimumab therapy Myocarditis developed despite low-dose steroids. Myocarditis responded to high-dose IV steroids (20 mg/Kg) and mycophenolate.

[PMID: 29567210 DOI: 10.1016/j.jacc.2018.02.037] [Citation(s) in RCA: 865] [Impact Index Per Article: 144.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 02/08/2018] [Accepted: 02/08/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Myocarditis is an uncommon, but potentially fatal, toxicity of immune checkpoint inhibitors (ICI). Myocarditis after ICI has not been well characterized. OBJECTIVES The authors sought to understand the presentation and clinical course of ICI-associated myocarditis. METHODS After observation of sporadic ICI-associated myocarditis cases, the authors created a multicenter registry with 8 sites. From November 2013 to July 2017, there were 35 patients with ICI-associated myocarditis, who were compared to a random sample of 105 ICI-treated patients without myocarditis. Covariates of interest were extracted from medical records including the occurrence of major adverse cardiac events (MACE), defined as the composite of cardiovascular death, cardiogenic shock, cardiac arrest, and hemodynamically significant complete heart block. RESULTS The prevalence of myocarditis was 1.14% with a median time of onset of 34 days after starting ICI (interquartile range: 21 to 75 days). Cases were 65 ± 13 years of age, 29% were female, and 54% had no other immune-related side effects. Relative to controls, combination ICI (34% vs. 2%; p < 0.001) and diabetes (34% vs. 13%; p = 0.01) were more common in cases. Over 102 days (interquartile range: 62 to 214 days) of median follow-up, 16 (46%) developed MACE; 38% of MACE occurred with normal ejection fraction. There was a 4-fold increased risk of MACE with troponin T of ≥1.5 ng/ml (hazard ratio: 4.0; 95% confidence interval: 1.5 to 10.9; p = 0.003). Steroids were administered in 89%, and lower steroids doses were associated with higher residual troponin and higher MACE rates. CONCLUSIONS Myocarditis after ICI therapy may be more common than appreciated, occurs early after starting treatment, has a malignant course, and responds to higher steroid doses.

Abstract
The Rohingya people of Myanmar (known as Burma before 1989) were stripped of citizenship in 1982, because they could not meet the requirement of proving their forefathers settled in Burma before 1823, and now account for one in seven of the global population of stateless people. Of the total 1·5 million Rohingya people living in Myanmar and across southeast Asia, only 82 000 have any legal protection obtained through UN-designated refugee status. Since 2012, more than 159 000 people, most of whom are Rohingya, have fled Myanmar in poorly constructed boats for journeys lasting several weeks to neighbouring nations, causing hundreds of deaths. We outline historical events preceding this complex emergency in health and human rights. The Rohingya people face a cycle of poor infant and child health, malnutrition, waterborne illness, and lack of obstetric care. In December, 2014, a UN resolution called for an end to the crisis. We discuss the Myanmar Government's ongoing treatment of Rohingya through the lens of international law, and the steps that the newly elected parliament must pursue for a durable solution.

Anticoagulation Is Associated with Decreased Inferior Vena Cava Filter-Related Complications in Patients with Metastatic Carcinoma. Am J Med 2017; 130:77-82.e1. [PMID: 27477669 DOI: 10.1016/j.amjmed.2016.06.048] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Revised: 06/18/2016] [Accepted: 06/20/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVES Patients with metastatic carcinoma and venous thromboembolism commonly have contraindications to anticoagulation that prompt the use of retrievable inferior vena cava filters. The aim of this study was to compare the pattern of inferior vena cava filter use, anticoagulation management, and development of inferior vena cava filter-related complications in patients with localized versus metastatic carcinoma. METHODS We conducted a retrospective cohort study of inferior vena cava filter use at a tertiary referral hospital between January 1, 2009, and December 31, 2011. Including only patients with cancer and carcinomas, both metastatic and localized, we recorded the indications for inferior vena cava filter, postfilter practices including anticoagulation use, filter retrieval rates, and filter-related complications. RESULTS Overall, 154 patients with carcinoma underwent inferior vena cava filter placement. Basic demographics and indication for filter placement were similar between the metastatic and localized groups. Metastatic patients had more filter-related complications (25% vs 11%, P = .03) and underwent filter retrieval less often (31% vs 58%, P = .01). Time to reinitiating anticoagulation was longer in metastatic patients (5.5 vs 2 days, P = .05). In multivariate analysis, metastatic disease was associated with reduced inferior vena cava filter retrieval (odds ratio, 0.3; P = .003). Anticoagulation use was associated with a lower rate of filter-related complications (odds ratio, 0.3; P = .005). CONCLUSIONS Patients with metastatic carcinoma with an indwelling inferior vena cava filter had a higher rate of filter-related complications, a lower filter retrieval rate, and a greater median time to initiating anticoagulation. When possible, early reinitiation of anticoagulation may reduce inferior vena cava filter-related complications.

Abstract
On Sept 29, 2013, the Framingham Heart Study will celebrate 65 years since the examination of the first volunteer in 1948. During this period, the study has provided substantial insight into the epidemiology and risk factors of cardiovascular disease. The origins of the study are closely linked to the cardiovascular health of President Franklin D Roosevelt and his premature death from hypertensive heart disease and stroke in 1945. In this Review we describe the events leading to the foundation of the Framingham Heart Study, and provide a brief historical overview of selected contributions from the study.

Abstract
UNLABELLED Smoking is one of the leading causes of death and two-thirds of the world's smokers live in 10 countries, including Bangladesh. This study examines the trend and differentials in smoking in Chakaria, Bangladesh. Data from 2 surveys conducted in 1994 and 2008 in Chakaria were used. RESULTS showed that smoking declined from 41% in 1994 to 27% in 2008. However, the decline was lower among the poor and the rate remained the same for the female illiterate. Interventions to prevent smoking need to be designed such that they are effective in disadvantaged groups and do not contribute to widening of socioeconomic inequalities in smoking prevalence and tobacco-related ill health and death.

GM-CSF promotes differentiation of human dendritic cells and T lymphocytes toward a predominantly type 1 proinflammatory response. Exp Hematol 2007; 35:1163-71. [PMID: 17562355 DOI: 10.1016/j.exphem.2007.05.001] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2007] [Revised: 05/03/2007] [Accepted: 05/03/2007] [Indexed: 11/30/2022]
Abstract
OBJECTIVE We recently demonstrated that patients with high levels of circulating dendritic cells (DC) and interleukin (IL)-12 are associated with reduced cancer relapse after hematopoietic stem cell transplantation. Identifying a growth factor that can promote these immune functions may have beneficial anti-tumor effects. We investigated the hypothesis that granulocyte-macrophage colony-stimulating factor (GM-CSF) induces IL-12 production and polarizes T lymphocytes toward a proinflammatory response. MATERIALS AND METHODS Peripheral blood mononuclear cells (PBMC), T lymphocytes, and antigen-presenting cells (APC) were cultured with GM-CSF and compared with no growth factors (control), G-CSF, or both GM-CSF and G-CSF. Cells were matured with either lipopolysaccharide or lectin (phytohemagglutinin). Type 1 and type 2 cytokines were measured by enzyme-linked immunosorbent assay. Induction of allogeneic T-lymphocyte proliferation induced by GM-CSF-stimulated APC was measured by mixed lymphocyte reaction. DC were measured by flow cytometry. RESULTS Levels of type 1 (IL-12, interferon-gamma, tumor necrosis factor-alpha) cytokines increased while type 2 (IL-10 and IL-4) cytokines decreased after stimulation of PBMC, T lymphocytes, and APC with GM-CSF. APC treated with GM-CSF induced higher proliferation of allogeneic T cells. CD11c and CD123-positive DC proliferated after exposure to GM-CSF. Both subtypes of DC (DC1 and DC2) were increased by GM-CSF. CONCLUSIONS GM-CSF induces production of type 1 proinflammatory cytokines by human PBMC, T lymphocytes, and APC. Type 2 cytokines are downregulated by GM-CSF and proliferation of allogeneic T cells is increased. These results demonstrate the potential for GM-CSF as a clinical agent for immune stimulation.
