Cytokine profiles in severe SARS-CoV-2 infection requiring extracorporeal membrane oxygenation support.

It has been postulated that the underlying pathophysiology of COVID-19 is mediated by cytokine storm resulting in a hyperinflammatory state. A similar kind of cytokine-storm has been described in individuals undergoing veno-venous extracorporeal membrane oxygenation (VV ECMO) support. There is therefore concern that initiation of VV ECMO support among COVID19 patients could further exacerbate this dysregulated inflammatory response.

Cytokine Profiles Before and After Immune Modulation in Hospitalized Patients with COVID-19.

We describe the cytokine profiles of a large cohort of hospitalized patients with moderate to critical COVID-19, focusing on IL-6, sIL2R, and IL-10 levels before and after receiving immune modulating therapies, namely, tocilizumab and glucocorticoids. We also discuss the possible roles of sIL2R and IL-10 as markers of ongoing immune dysregulation after IL-6 inhibition. We performed a retrospective chart review of adult patients admitted to a tertiary care center with moderate to critical SARS-CoV-2 infection.

A retrospective matched cohort single-center study evaluating outcomes of COVID-19 and the impact of immunomodulation on COVID-19-related cytokine release syndrome in solid organ transplant recipients.

This retrospective matched cohort study describes 30 solid organ transplant (SOT) patients with Coronavirus Disease 2019 (COVID-19) matched 1:2 to 60 non-SOT patients (control group) based on age, body mass index (BMI), and comorbidities (hypertension and diabetes mellitus with hemoglobin A1c > 8.0%). The SOT group had a higher proportion of cardiovascular disease (P < .

Clinical presentation of hereditary angioedema.

Hereditary angioedema (HAE) is a rare, autosomal dominant disease caused by a deficiency in the C1-inhibitor protein. It is characterized by recurrent episodes of nonpruritic, nonpitting, subcutaneous or submucosal edema that typically involves the extremities or the gastrointestinal tract. However, the genitourinary tract, face, oropharynx, and/or larynx may be affected as well.

Tocilizumab Treatment for Cytokine Release Syndrome in Hospitalized Patients With Coronavirus Disease 2019: Survival and Clinical Outcomes.

Background: Tocilizumab, an IL-6 receptor antagonist, can be used to treat cytokine release syndrome (CRS), with observed improvements in a coronavirus disease 2019 (COVID-19) case series.

Research Question: The goal of this study was to determine if tocilizumab benefits patients hospitalized with COVID-19.

Study Design And Methods: This observational study of consecutive COVID-19 patients hospitalized between March 10, 2020, and March 31, 2020, and followed up through April 21, 2020, was conducted by chart review.

Repurposing antimicrobial stewardship tools in the electronic medical record for the management of COVID-19 patients.

During the COVID-19 pandemic, the antimicrobial stewardship module in our electronic medical record was reconfigured for the management of COVID-19 patients. This change allowed our subspecialist providers to review charts quickly to optimize potential therapy and management during the patient surge.

Etoposide phosphate for pediatric orthopedic malignancies after intravenous etoposide hypersensitivity.

Background: Hypersensitivity reactions to etoposide have been reported and patients have been safely transitioned to etoposide phosphate for continued therapy. However, the safety and efficacy of substituting etoposide phosphate for etoposide has not been well established in pediatric orthopedic malignancies. The aim of this study is to determine whether etoposide phosphate can be substituted for etoposide in pediatric orthopedic malignancies.

Hyperbilirubinemia following lenalidomide administration.

Asymptomatic hyperbilirubinemia in a patient with no underlying liver disease or renal impairment while on lenalidomide therapy may be attributable to the unmasking of previously undiagnosed Gilbert's syndrome, as previously shown in the literature. The hyperbilirubinemia should resolve after discontinuation of the drug.
