ABSTRACT
Tocilizumab (TCZ), a humanized monoclonal antibody targeting the interleukin-6 receptor, holds the potential for treating coronavirus disease 2019 (COVID-19) patients, particularly those at high risk of cytokine storm syndrome. However, data regarding the clinical impact of treatment with TCZ in patients with COVID-19 are limited. This study was conducted to evaluate the safety and effectiveness of TCZ as an adjunct therapy for the treatment of severe COVID-19 infection. This was a retrospective observational chart review of confirmed COVID-19 patients who received TCZ, along with other COVID-19 therapies. The outcomes of interest included changes in vital signs such as temperature and laboratory biomarkers, duration of mechanical ventilation, adverse events possibly associated with TCZ, and intensive care unit and hospital lengths of stay. This study included 38 patients with an average age of 63 years (IQR, 48-70 years). The average dose of TCZ given was 519 ± 61 mg. Median C-reactive protein significantly decreased following TCZ administration (189.9 vs 54.8 mg/L, P = .003). Nineteen of all febrile patients before the initiation of TCZ (73%) became fever free on the fourth day of TCZ treatment. Following TCZ treatment, 11 patients developed infections because of multidrug-resistant bacteria, and elevated liver transaminases were observed in 6 patients. The preliminary findings of this study suggested TCZ appeared to ameliorate COVID-19-related cytokine storm syndrome. However, large randomized, controlled trials are needed to investigate whether treatment with TCZ is associated with better outcomes in COVID-19.

Over the past several months we have learned about how pre-existent comorbidities may influence the outcome of patients infected with the coronavirus disease 2019 (COVID-19), with diabetes mellitus and obesity being commonly reported in association with increased mortality among these patients. In this report, the authors explore the case of a patient with Fragile-X Syndrome (FXS) who developed pneumonia due to COVID-19. FXS is an inherited cause of intellectual disability with potential neurologic and physiologic sequelae. In this narrative, we aim to describe how FXS may potentially play a role in the clinical course of patients with COVID-19.
ABSTRACT
Background The novel coronavirus disease 2019 (COVID-19) pandemic continues to spread across the country with over 3 million cases and 150,000 deaths in the United States as of July 2020. Outcomes have been poor, with reported admission rates to the intensive care team of 5% in China and mortality among critically ill patients of 50% in Seattle. Here we explore the disease characteristics in a Brooklyn safety-net hospital affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Methods A retrospective chart review of COVID-19 positive patients at The Brooklyn Hospital Center who were treated by the intensive care team prior to April 20, 2020. Data was extracted from the electronic health record, analyzed and correlated for outcome. Results Impact of various clinical treatments was assessed, showing no change in median overall survival (OS) of both hydroxychloroquine with azithromycin or vitamin C with zinc. Supplemental therapies were used in selected patients, and some were shown to increase median OS and patients requiring vasopressor support or invasive mechanical ventilation showed decreased OS. There was no statistically significant difference in overall survival based on ethnicity, healthcare status, or individual medical comorbidities, although a negative trend exists for diabetes. Despite this, there is a trend towards increasingly poor prognosis based on the number of comorbidities and Class 3 obesity. Conclusions Despite the fact that we show no significant differences in mortality based on ethnicity, insurance status, or individual medical comorbidities, we show a high overall mortality. There is also a trend towards increased overall mortality in Class 3 obesity, which should be further investigated. We suggest that these findings may be attributed to both socioeconomic factors and an increased incidence of total medical comorbidities in our patient population.
