BACKGROUND:
Bebtelovimab is a monoclonal antibody used to prevent progression of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Complications of SARS-CoV-2 infection can ...include cardiac effects including sinus bradycardia.
CASE SUMMARY:
We describe the case of an 86-year-old male infected with SARS-CoV-2 who experienced bradycardia with cardiac arrest immediately following infusion of Bebtelovimab with return of spontaneous circulation obtained following 1 minute of chest compressions and administration of atropine. His bradycardia resolved, and he was extubated on hospital day 1, found to be neurologically intact, and discharged on hospital day 9.
CONCLUSIONS:
Due to the time course of the patient’s symptomatology, we attribute the bradycardic arrest to the Bebtelovimab infusion. This case illustrates the need for further research into the etiology of bradycardia due to SARS-CoV-2 infection and to examine potential links to monoclonal antibody infusion. It also serves as important caution to maintain close cardiac monitoring while administering monoclonal antibodies for SARS-CoV-2.
This protocol aids both new and experienced researchers in designing retrospective clinical and translational studies of acute respiratory decline in hospitalized patients. This protocol addresses ...(1) the basics of respiratory failure and electronic health record research, (2) defining patient cohorts as “mild, progressive, or severe” instead of “ICU versus non-ICU”, (3) adapting physiological indices, and (4) using biomarker trends. We apply these approaches to inflammatory biomarkers in COVID-19, but this protocol can be applied to any progressive respiratory failure study.

To establish the feasibility of empirically testing crisis standards of care guidelines.
Retrospective single-center study.
ICUs at a large academic medical center in the United States.
Adult, ...critically ill patients admitted to ICU, with 27 patients admitted for acute respiratory failure due to coronavirus disease 2019 and 37 patients admitted for diagnoses other than coronavirus disease 2019.
Review of electronic health record.
Many U.S. states released crisis standards of care guidelines with algorithms to allocate scarce healthcare resources during the coronavirus disease 2019 pandemic. We compared state guidelines that represent different approaches to incorporating disease severity and comorbidities: New York, Maryland, Pennsylvania, and Colorado. Following each algorithm, we calculated priority scores at the time of ICU admission for a cohort of patients with primary diagnoses of coronavirus disease 2019 and diseases other than coronavirus disease 2019 (n = 64). We assessed discrimination of 28-day mortality by area under the receiver operating characteristic curve. We simulated real-time decision-making by applying the triage algorithms to groups of two, five, or 10 patients. For prediction of 28-day mortality by priority scores, area under the receiver operating characteristic curve was 0.56, 0.49, 0.53, 0.66, and 0.69 for New York, Maryland, Pennsylvania, Colorado, and raw Sequential Organ Failure Assessment score algorithms, respectively. For groups of five patients, the percentage of decisions made without deferring to a lottery were 1%, 57%, 80%, 88%, and 95% for New York, Maryland, Pennsylvania, Colorado, and raw Sequential Organ Failure Assessment score algorithms, respectively. The percentage of decisions made without lottery was higher in the subcohort without coronavirus disease 2019, compared with the subcohort with coronavirus disease 2019.
Inclusion of comorbidities does not consistently improve an algorithm's performance in predicting 28-day mortality. Crisis standards of care algorithms result in a substantial percentage of tied priority scores. Crisis standards of care algorithms operate differently in cohorts with and without coronavirus disease 2019. This proof-of-principle study demonstrates the feasibility and importance of empirical testing of crisis standards of care guidelines to understand whether they meet their goals.
In this single-center, retrospective cohort analysis of hospitalized coronavirus disease 2019 (COVID-19) patients, we investigate whether inflammatory biomarker levels predict respiratory decline in ...patients who initially present with stable disease. Examination of C-reactive protein (CRP) trends reveals that a rapid rise in CRP levels precedes respiratory deterioration and intubation, although CRP levels plateau in patients who remain stable. Increasing CRP during the first 48 h of hospitalization is a better predictor (with higher sensitivity) of respiratory decline than initial CRP levels or ROX indices (a physiological score of respiratory function). CRP, the proinflammatory cytokine interleukin-6 (IL-6), and physiological measures of hypoxemic respiratory failure are correlated, which suggests a mechanistic link. Our work shows that rising CRP predicts subsequent respiratory deterioration in COVID-19 and may suggest mechanistic insight and a potential role for targeted immunomodulation in a subset of patients early during hospitalization.

Mueller et al. demonstrate in hospitalized COVID-19 patients that trending C-reactive protein (CRP), an inflammatory biomarker, is a simple and accessible strategy for predicting respiratory deterioration. An early rise in CRP predicts intubation, and CRP levels correlate with IL-6 levels and physiological measures of hypoxemic respiratory failure.

Microcephalic primordial dwarfism is a group of disorders that result in growth restriction and multiple morbidities. The condition is subdivided into three categories, with microcephalic ...osteodysplastic primordial dwarfism type II (MOPDII) being the most prevalent. Globally, only a few cases have been reported, with only available information about these disorders described in the literature. In this case report, we present the clinical findings seen in an infant with MOPDII in Saudi Arabia with associated glucose-6-phosphate dehydrogenase deficiency hemolytic anemia.
