Cardiovascular outcomes after tixagevimab and cilgavimab use for pre-exposure prophylaxis against COVID-19: a population-based propensity-matched cohort study.

Tixagevimab and cilgavimab treatment was associated with higher rates of cardiovascular events in a post-hoc analysis of a phase 3 trial. In this large population-based propensity-matched study, we found no increased risk of cardiovascular events up to 90 days after tixagevimab and cilgavimab administration, including in patients with pre-existing cardiovascular disease.

Acute pulmonary emboli following rebound phenomenon after Nirmatrelvir/Ritonavir treatment for COVID-19.

The return of COVID-19 symptoms after Nirmatrelvir/Ritonavir (Nm/R) treatment is being increasingly reported. Limited evidence suggests most cases of rebound symptoms are mild and do not require further intervention. Here we present a male veteran reporting rebound symptoms who was found to be hypoxic with pulmonary emboli. Our case highlights the need to evaluate known complications of SARS-CoV-2 including venous thromboembolism in patients reporting recurring symptoms. Further, cases of severe rebound phenomenon should continue to be reported by clinicians to better appreciate the use of the Nm/R during the Omicron wave and among vaccinated persons.

Mucocutaneous disease and related clinical characteristics in hospitalized children and adolescents with COVID-19 and multisystem inflammatory syndrome in children.

BACKGROUND: Little is known about mucocutaneous disease in acutely ill children and adolescents with COVID-19 and multisystem inflammatory syndrome in children (MIS-C). OBJECTIVE: To characterize mucocutaneous disease and its relation to clinical course among hospitalized patients with COVID-19 and MIS-C. METHODS: Descriptive cohort study of prospectively and consecutively hospitalized eligible patients between May 11, 2020 and June 5, 2020. RESULTS: In COVID-19 patients, 4 of 12 (33%) had rash and/or mucositis, including erythema, morbilliform pattern, and lip mucositis. In MIS-C patients, 9 of 19 (47%) had rash and/or mucositis, including erythema, morbilliform, retiform purpura, targetoid and urticarial patterns, along with acral edema, lip mucositis, tongue papillitis, and conjunctivitis. COVID-19 patients with rash had less frequent respiratory symptoms, pediatric intensive care unit admission, invasive ventilation, and shorter stay versus COVID-19 patients without rash. MIS-C patients with rash had less frequent pediatric intensive care unit admission, shock, ventilation, as well as lower levels of C-reactive protein, ferritin, D-dimer, and troponin (vs MIS-C without rash). Neutrophil-to-lymphocyte ratio was similar for patients with and without rash in both groups. None of the MIS-C patients met criteria for Kawasaki disease. LIMITATIONS: Small sample sizes. CONCLUSIONS: Mucocutaneous disease is common among children and adolescents with COVID-19 and MIS-C. Laboratory trends observed in patients with rash may prognosticate a less severe course.

Internet Searches About Infectious Diseases Training During the Coronavirus Disease 2019 Pandemic.

The COVID- 19 pandemic has showcased the field of Infectious Diseases (ID). We used Google Trends to find that this newfound attention has led to higher interest in ID training.

Eruptions and related clinical course among 296 hospitalized adults with confirmed COVID-19.

BACKGROUND: Limited information exists on mucocutaneous disease and its relation to course of COVID-19. OBJECTIVE: To estimate prevalence of mucocutaneous findings, characterize morphologic patterns, and describe relationship to course in hospitalized adults with COVID-19. METHODS: Prospective cohort study at 2 tertiary hospitals (Northwell Health) between May 11, 2020 and June 15, 2020. RESULTS: Among 296 hospitalized adults with COVID-19, 35 (11.8%) had at least 1 disease-related eruption. Patterns included ulcer (13/35, 37.1%), purpura (9/35, 25.7%), necrosis (5/35, 14.3%), nonspecific erythema (4/35, 11.4%), morbilliform eruption (4/35, 11.4%), pernio-like lesions (4/35, 11.4%), and vesicles (1/35, 2.9%). Patterns also showed anatomic site specificity. A greater proportion of patients with mucocutaneous findings used mechanical ventilation (61% vs 30%), used vasopressors (77% vs 33%), initiated dialysis (31% vs 9%), had thrombosis (17% vs 11%), and had in-hospital mortality (34% vs 12%) compared with those without mucocutaneous findings. Patients with mucocutaneous disease were more likely to use mechanical ventilation (adjusted prevalence ratio, 1.98; 95% confidence interval, 1.37-2.86); P < .001). Differences for other outcomes were attenuated after covariate adjustment and did not reach statistical significance. LIMITATIONS: Skin biopsies were not performed. CONCLUSIONS: Distinct mucocutaneous patterns were identified in hospitalized adults with COVID-19. Mucocutaneous disease may be linked to more severe clinical course.
