Immune checkpoint inhibitors have greatly improved clinical outcomes in multiple cancer types and are increasingly being used in earlier disease settings and in combination with other therapies.1 ...However, high-grade immune-related adverse events can occur. Patients had a wide spectrum of age (median 69 years range 20-90), cancer types (most commonly melanoma and lung cancer), and geographical location (appendix).

The considerable progress made in the field of cancer treatment has led to a dramatic improvement in the prognosis of patients with cancer. However, toxicities resulting from these treatments ...represent a cost that can be harmful to short- and long-term outcomes. Adverse events affecting the cardiovascular system are one of the greatest challenges in the overall management of patients with cancer, as they can compromise the success of the optimal treatment against the tumor. Such adverse events are associated not only with older chemotherapy drugs such as anthracyclines but also with many targeted therapies and immunotherapies. Recognizing this concern, several American and European governing societies in oncology and cardiology have published guidelines on the cardiovascular monitoring of patients receiving potentially cardiotoxic cancer therapies, as well as on the management of cardiovascular toxicities. However, the low level of evidence supporting these guidelines has led to numerous discrepancies, leaving clinicians without a consensus strategy to apply. A cardio-oncology expert panel from the French Working Group of Cardio-Oncology has undertaken an ambitious effort to analyze and harmonize the most recent American and European guidelines to propose roadmaps and decision algorithms that would be easy for clinicians to use in their daily practice. In this statement, the experts addressed the cardiovascular monitoring strategies for the cancer drugs associated with the highest risk of cardiovascular toxicities, as well as the management of such toxicities.
Background
Immune checkpoint inhibitors (ICIs) have transformed cancer therapy but may also trigger autoimmune adverse drug reactions (ADRs) referred to as immune‐related adverse events (irAEs). ...Although endocrinopathies are among the most common form of irAEs, primary adrenal insufficiency (PAI) is infrequent and has only been published in case reports. The aim of this study was to identify and characterize the main features of PAI‐irAE.
Materials and Methods
Suspected PAI‐irAE cases were identified using VigiBase, the World Health Organization's pharmacovigilance database of individual case safety reports.
Results
From September 2, 2008, through October 5, 2018, a total of 50,108 ICI‐associated ADRs were reported. Since 2008, there were 451 cases of PAI‐irAE identified of which 45 were “definite PAI” and 406 “possible PAI.” Patients were mainly male (58.1%) with a median age of 66 years (range, 30–95). Indications of ICI were predominantly for melanoma (41.2%) and lung cancer (28.6%). The majority of patients were treated with ICI monotherapy (nivolumab: 44.3%, pembrolizumab: 11.7%, ipilimumab: 23.6%), and 17.9% were treated with ICI combination therapy. These events occurred with a median time to onset of 120 days (range, 6–576). ICI‐associated PAI was associated with significant morbidity (≥90% severe) and mortality (7.3%). Fatality rates were similar in the subgroups of combination therapy versus monotherapy. There were no relevant differences in clinical or demographical characteristics and outcomes between “definite” versus “possible” PAI group.
Conclusion
Our study represents the largest clinical description and characterization of PAI‐irAE. Although ICI‐associated PAI is a rare adverse event, early recognition is important to implement corticosteroid treatment. Further studies are required to elucidate risk factors and reversibility of this rare but severe irAE. Clinical trial identification number. NCT03492242
Implications for Practice
Immune checkpoint inhibitor (ICI)‐associated primary adrenal insufficiency (PAI) is a rare adverse event that is important to recognize because it may be severe and life‐threatening, requiring emergent and often lifelong hormonal replacement therapy. Awareness regarding this ICI‐related endocrinopathy is strongly encouraged among clinicians in addition to patient education about common PAI symptoms that should prompt urgent medical evaluation. In clinical practice, close monitoring and investigation for PAI is crucial to allow for early management and to further define the pathophysiology and prognosis of ICI‐PAI. Corticotrophin (adrenocorticotrophic hormone) circulating level evaluation may be often lacking but should be considered as part of the diagnostic workup to differentiate PAI from secondary (central) adrenal insufficiency.
Limited data are available for immune‐related adverse events related to primary adrenal insufficiency. This article characterizes such events using Vigibase, the WHO's global database of individual case safety reports.

Immune checkpoint inhibitors have improved outcomes for patients with numerous hematological and solid cancers. Hematologic toxicities have been described, but the spectrum, timing, and clinical ...presentation of these complications are not well understood. We used the World Health Organization's pharmacovigilance database of individual‐case‐safety‐reports (ICSRs) of adverse drug reactions, VigiBase, to identify cases of hematologic toxicities complicating immune checkpoint inhibitor therapy. We identified 168 ICSRs of immune thrombocytopenic purpura (ITP), hemolytic anemia (HA), hemophagocytic lymphohistiocytosis, aplastic anemia, and pure red cell aplasia in 164 ICSRs. ITP (n = 68) and HA (n = 57) were the most common of these toxicities and occurred concomitantly in four patients. These events occurred early on treatment (median 40 days) and were associated with fatal outcome in 12% of cases. Ipilimumab‐based therapy (monotherapy or combination with anti‐programmed death‐1 PD‐1) was associated with earlier onset (median 23 vs. 47.5 days, p = .006) than anti‐PD‐1/programmed death ligand‐1 monotherapy. Reporting of hematologic toxicities has increased over the past 2 years (98 cases between January 2017 and March 2018 vs. 70 cases before 2017), possibly because of increased use of checkpoint inhibitors and improved recognition of toxicities. Future studies should evaluate incidence of hematologic toxicities, elucidate risk factors, and determine the most effective treatment algorithms.
Key Points
Immune‐mediated hematologic toxicities are a potential side effect of immune checkpoint inhibitors (ICIs).
Providers should monitor complete blood counts during treatment with ICIs.
Corticosteroids are the mainstay of treatment for immune‐mediated hematologic toxicities.
Further research is needed to define patient‐specific risk factors and optimal management strategies for hematologic toxicities.
Immune checkpoint inhibitors (ICIs) have improved outcomes for patients with cancer but related hematologic toxicities have been poorly described. Using VigiBase, the World Health Organization's pharmacovigilance database of individual case safety reports of adverse drug reactions, this study aimed to identify such cases of hematologic toxicities.

Ibrutinib has revolutionized treatment for several B-cell malignancies. However, a recent clinical trial where ibrutinib was used in a front-line setting showed increased mortality during treatment ...compared with conventional chemotherapy. Cardiovascular toxicities were suspected as the culprit but not directly assessed in the study.
The purpose of this study was to identify and characterize cardiovascular adverse drug reactions (CV-ADR) associated with ibrutinib.
This study utilized VigiBase (International pharmacovigilance database) and performed a disproportionality analysis using reporting odds ratios (ROR) and information component (IC) to determine whether CV-ADR and CV-ADR deaths were associated with ibrutinib. IC compares observed and expected values to find associations between drugs and adverse drug reactions using disproportionate Bayesian-reporting; IC025 (lower end of the IC 95% credibility interval) >0 is significant.
This study identified 303 ibrutinib-associated cardiovascular deaths. Ibrutinib was associated with higher reporting of supraventricular arrhythmias (SVAs) (ROR: 23.1; 95% confidence interval: 21.6 to 24.7; p < 0.0001; IC025: 3.97), central nervous system (CNS) hemorrhagic events (ROR: 3.7; 95% confidence interval: 3.4 to 4.1; p < 0.0001; IC025: 1.63), heart failure (ROR: 3.5; 95% confidence interval: 3.1 to 3.8; p < 0.0001; IC025: 1.46), ventricular arrhythmias (ROR: 4.7; 95% confidence interval: 3.7 to 5.9; p < 0.0001; IC025: 0.96), conduction disorders (ROR: 3.5; 95% confidence interval: 2.7 to 4.6; p < 0.0001; IC025: 0.76), CNS ischemic events (ROR: 2.2; 95% confidence interval: 2.0 to 2.5; p < 0.0001; IC025: 0.73), and hypertension (ROR: 1.7; 95% confidence interval: 1.5 to 1.9; p < 0.0001; IC025: 0.4). CV-ADR often occurred early after ibrutinib administration. Importantly, CV-ADR were associated with fatalities that ranged from ∼10% (SVAs and ventricular arrhythmias) to ∼20% (CNS events, heart failure, and conduction disorders). Ibrutinib-associated SVA portends poor prognosis when CNS events occur concomitantly, with 28.8% deaths (15 of 52 cases).
Severe and occasionally fatal cardiac events occur in patients exposed to ibrutinib. These events should be considered in patient care and in clinical trial designs. (Evaluation of Reporting of Cardio-vascular Adverse Events With Antineoplastic and Immunomodulating Agents EROCA; NCT03530215)

COVID‐19 is associated with encephalitis in critically ill patients and endothelial dysfunction seems to contribute to this life‐threatening complication. Our objective was to determine the hallmark ...of endothelial activation in COVID‐19‐related encephalitis. In an observational study in intensive care unit (ICU), we compared vascular biomarkers of critically ill COVID‐19 patients with or without encephalitis. To be classified in the encephalitis group, patients had to have new onset of central neurologic symptom, and pathological findings on either brain magnetic resonance imaging (MRI) and/or electroencephalogram (EEG). Among the 32 critically ill COVID‐19 consecutive patients, 21 were categorized in the control group and 11 in the encephalitis group. Encephalitis patients had a longer ICU stay than control patients (median length 25th–75th percentile of 52 16–79 vs. 20.5 11–44 days, respectively, p = 0.04). Nine‐month overall follow‐up mortality reached 21% (7/32 patients), with mortality rates in the encephalitis group and the control group of 27% and 19%, respectively. Encephalitis was associated with significant higher release of soluble endothelial activation markers (sE‐selectin, tumor necrosis factor‐α (TNF‐α), interleukin 6, placental growth factor, and thrombomodulin), but these increases were correlated with TNF‐α plasmatic levels. The hypoxia‐inducible protein angiopoietin‐like 4 (ANGPTL4) was at significantly higher levels in encephalitis patients compared to control patients (p = 0.0099), and in contrary to the other increased factors, was not correlated with TNF‐α levels (r = 0.2832, p = 0.1163). Our findings suggest that COVID‐19‐related encephalitis is a cytokine‐associated acute brain dysfunction. ANGPTL4 was the only elevated marker found in encephalitis patients, which was not correlated with systemic inflammation, suggesting that ANGPTL4 might be a relevant factor to predict encephalitis in critically ill COVID‐19 patients.
COVID‐19 is associated with encephalitis in critically ill patients with acute respiratory distress syndrome (ARDS). Endothelial dysfunction contributes to this complication. Our findings suggest that COVID‐19‐related encephalitis in critically ill patients is consecutive to the systemic inflammation following ARDS. This inflammation leads to an endothelial cell dysfunction through the increase in cell surface adhesion molecules expression, brain endothelial cell permeability, and coagulation dysregulation. However, angiopoietin‐like 4 (ANGPTL4), a secreted glycoprotein, was the only elevated marker found in encephalitis patients, which was not correlated with systemic inflammation. ANGPTL4 role (cause or consequence) in COVID‐19 encephalitis remains to be determined.
