The cytokine release syndrome (CRS) is the most common complication after adoptive immunotherapies such as chimeric antigen receptor T cells (CAR-T). The incidence varies from 30 to 100% depending on the CAR-T construct, cell doses and the underlying disease. Severe cases may involve 10 to 30% of patients. The triggering event is the activation of the CAR-T, after meeting with their target. The T cell activation leads to the release of effector cytokines, such as IFNγ, TNFα and IL2, that are responsible for the activating of monocyte/macrophage system, resulting in the production of pro-inflammatory cytokines, (including IL6, IFN-γ, IL10, MCP1) and associated with a significant elevation of CRP and ferritin...

Angiotensin II (ANG-2) is a novel vasopressor recently approved for the treatment of vasodilatory shock. We describe a case where ANG-2 was successfully used to treat post cardiopulmonary bypass (CPB) vasoplegic syndrome (VS) in a patient refractory to standard vasopressors and other rescue therapies. Despite requiring high dose vasopressors, the patient was extubated within 24 hours and was met key quality metrics defined by the Society of Thoracic Surgeons (STS).

In this case report, we describe 2 patients with septic shock requiring high-dose vasopressors for hemodynamic support despite aggressive fluid resuscitation. After the administration of high-dose hydroxocobalamin for presumed septic vasoplegic syndrome, both patients had an immediate response to hydroxocobalamin with a rapid and lasting improvement of blood pressure that significantly reduced the need for vasopressor support.

Background Postoperative clinical outcomes associated with the preoperative continuation or discontinuation of angiotensin-converting enzyme inhibitors ( ACEIs ) or angiotensin receptor blockers ( ARBs ) before cardiac surgery remain unclear. Methods and Results In a single-center, open-label, randomized, registry-based clinical trial, patients undergoing nonemergent cardiac surgery were assigned to ACEI / ARB continuation or discontinuation 2 days before surgery. Among the 584 patients screened, 261 met study criteria and 126 (48...

INTRODUCTION: Serotonin syndrome (SS) is a potentially serious side effect of serotonergic drugs. Cases of SS have been reported from the administration of methylene blue (MB), an agent with monoamine oxidase inhibiting properties. To date, the reported cases of MB-induced SS have all been with MB given parenterally. We report a case induced by the initiation of an MB-containing oral agent. METHODS: A case of SS felt to be induced by the initiation of an MB containing orally administered urinary analgesic, started in a patient concurrently treated with multiple serotonergic psychiatric drugs, is presented...

BACKGROUND: In general, patients with sepsis die from the host response to the infecting pathogen rather than from the infecting pathogen itself. Four patterns of death have been identified in sepsis, namely vasoplegic shock, single-organ respiratory failure (acute respiratory distress syndrome [ARDS]), multi-system organ failure (MSOF), and persistent MSOF with ongoing inflammation and immunosuppression with recurrent infections (persistent inflammation-immunosuppression and catabolism syndrome [PICS])...

Vasoplegia is the syndrome of pathological low systemic vascular resistance, the dominant clinical feature of which is reduced blood pressure in the presence of a normal or raised cardiac output. The vasoplegic syndrome is encountered in many clinical scenarios, including septic shock, post-cardiac bypass and after surgery, burns and trauma, but despite this, uniform clinical definitions are lacking, which renders translational research in this area challenging. We discuss the role of vasoplegia in these contexts and the criteria that are used to describe it are discussed...

BACKGROUND: Vasoplegia is a clinical condition typically manifested by cardiovascular instability unresponsive to usual doses of inotropes or vasopressors. It can occur in a variety of clinical settings including liver transplantation (LT). Immunoglobulins have been used to treat sepsis-related vasoplegia. We performed a retrospective study to evaluate the efficacy of IgM-enriched immunoglobulin (IgMIg) on 30-day mortality and its ability to reverse vasoplegia in patients undergoing LT...

Metformin is a common and generally well-tolerated medication in the treatment of diabetes but rarely has been implicated as the cause for metformin-associated lactate acidosis. This is usually caused by decreased elimination from renal dysfunction but is rarely described after an acute ingestion. We present a case of an acute intentional overdose of metformin in a metformin-naïve patient without renal dysfunction. The patient gradually developed altered mental status, tachypnea, hypotension, hyperglycemia, hypoglycemia, hypothermia, and vasoplegic shock unresponsive to vasopressor support...

The objective of the study was to report our institutional experience in the management of children and newborns with refractory septic shock who required venoarterial extracorporeal membrane oxygenation (VA ECMO) treatment, and to identify patient-and infection-related factors associated with mortality. This is a retrospective case series in an intensive care unit of a tertiary pediatric center. Inclusion criteria were patients ≤ 18 years old who underwent a VA ECMO due to a refractory septic shock due to circulatory collapse...

BACKGROUND: Cardiopulmonary bypass (CPB) is associated with a systemic inflammatory response and an endothelial dysfunction, whose qualitative assessment appears to be a major issue. Endocan (ESM-1, endothelial cell specific molecule-1) is a protein preferentially expressed by the endothelium and previously associated with prognosis of septic shock or acute respiratory distress syndrome. In this pilot study, we investigated the kinetic of Endocan in planned coronary artery bypass grafting (CABG) surgery with CPB...

OBJECTIVES: Sterile and infectious critical illnesses often result in vasoplegic shock and a robust systemic inflammatory response that are similar in presentation. The innate immune system is at the center of the response to both infectious and traumatic insults. Damage-associated molecular patterns are small molecules that are released from stressed or dying cells. Damage-associated molecular patterns activate pattern recognition receptors and coordinate the leading edge of the innate immune response...

PURPOSE: Postoperative vasoplegic shock after cardiac surgery seems to be a frequent complication with poor outcomes. We hypothesized that vasopressin may increase the risk of poor outcomes in patients with preoperative Left Ventricular Dysfunction (pLVD) rather than norepinephrine. The aim of this study was to assess whether vasopressin is superior to norepinephrine to improve outcomes in patients with pLVD after cardiac surgery. METHODS: This retrospective cohort study included 1,156 patients with postoperative vasoplegic shock (mean arterial pressure <65 mmHg resistant to fluid challenge and cardiac index >2...

Vasoplegic syndrome, characterized by low systemic vascular resistance and hypotension in the presence of normal or supranormal cardiac function, is a frequent complication of cardiovascular surgery. It is associated with a diffuse systemic inflammatory response and is mediated largely through cellular hyperpolarization, high levels of inducible nitric oxide, and a relative vasopressin deficiency. Cardiopulmonary bypass is a particularly strong precipitant of the vasoplegic syndrome, largely due to its association with nitric oxide production and severe vasopressin deficiency...

PURPOSE OF REVIEW: To evaluate the efficacy, dosing, and safety of methylene blue (MTB) in perioperative vasoplegic syndrome (VS). RECENT FINDINGS: Vasoplegic syndrome is a state of persistent hypotension with elevated cardiac output, low filling pressures, and low systemic vascular resistance (SVR). It occurs in up to 25% of patients undergoing cardiac surgery with cardiopulmonary bypass, can last up to 72 h, and is associated with a high mortality rate. MTB has been found to increase SVR and decrease vasopressor requirements in vasoplegic syndrome by inhibiting nitric oxide synthase, thus limiting the generation of nitric oxide, while inhibiting activation of soluble guanylyl cyclase and preventing vasodilation...

INTRODUCTION: Management of severe vasoplegic shock in overdose can be very challenging. We describe a case of severe refractory vasodilatory shock in poisoning where methylene blue (MB) was used with success. However, the patient subsequently developed severe Serotonin Syndrome (SS) as a result of an interaction between serotonergic drugs and MB. CASE REPORT: A 15-year-old male developed severe vasoplegic shock 1.5 hours after overdosing on several different medications including quetiapine slow release, quetiapine immediate release, desvenlafaxine slow release, venlafaxine, amlodipine, ramipril, fluoxetine, promethazine and lithium...

Methylene blue is a phenothiazine-related heterocyclic aromatic molecule presently used in the treatment of methemoglobinemia. Recently, it has been implicated in the treatment of severe refractory vasoplegic shock caused by anaphylaxis, sepsis, or postcardiopulmonary bypass. We present a case of a 27-year-old male with profound vasoplegic shock of unknown etiology which was refractory to vasopressors who responded within hours to a single dose of methylene blue. Additionally, we review the evidence of methylene blue's role in the treatment of shock...

Vasopressin is a potent vasopressor used for improving organ perfusion during cardiac arrest, septic and catecholamine-resistant shock; with reference to this, it is useful for the treatment of vasoplegic shock because, restoring organ perfusion pressure by contraction of vascular smooth muscle through a non-catecholamine receptor pathway, it can be employed when catecholamines are ineffective. A 49-yr-old woman was admitted to the Emergency Department after having intentionally taken 95.2g of metformin, 1...

Vasoplegic syndrome is a form of vasodilatory shock that occurs frequently in patients who undergo cardiac surgery requiring cardiopulmonary bypass (CBP). Treatment often demands high doses of vasopressors over sustained periods for hypotension that can be refractory to standard vasoactive medications. Furthermore, the development of vasoplegia greatly contributes to morbidity and mortality following cardiac surgery. Methylene blue (MB) has become a popular therapy for cardiac vasoplegia despite a paucity of prospective data to direct its use...
