Importance: Coronavirus disease 2019 (COVID-19) may lead to serious illness as a result of an excessive immune response. Fluvoxamine may prevent clinical deterioration by stimulating the σ-1 receptor, which regulates cytokine production. Objective: To determine whether fluvoxamine, given during mild COVID-19 illness, prevents clinical deterioration and decreases the severity of disease. Design, Setting, and Participants: Double-blind, randomized, fully remote (contactless) clinical trial of fluvoxamine vs placebo. Participants were community-living, nonhospitalized adults with confirmed severe acute respiratory syndrome coronavirus 2 infection, with COVID-19 symptom onset within 7 days and oxygen saturation of 92% or greater. One hundred fifty-two participants were enrolled from the St Louis metropolitan area (Missouri and Illinois) from April 10, 2020, to August 5, 2020. The final date of follow-up was September 19, 2020. Interventions: Participants were randomly assigned to receive 100 mg of fluvoxamine (n = 80) or placebo (n = 72) 3 times daily for 15 days. Main Outcomes and Measures: The primary outcome was clinical deterioration within 15 days of randomization defined by meeting both criteria of (1) shortness of breath or hospitalization for shortness of breath or pneumonia and (2) oxygen saturation less than 92% on room air or need for supplemental oxygen to achieve oxygen saturation of 92% or greater. Results: Of 152 patients who were randomized (mean [SD] age, 46 [13] years; 109 [72%] women), 115 (76%) completed the trial. Clinical deterioration occurred in 0 of 80 patients in the fluvoxamine group and in 6 of 72 patients in the placebo group (absolute difference, 8.7% [95% CI, 1.8%-16.4%] from survival analysis; log-rank P = .009). The fluvoxamine group had 1 serious adverse event and 11 other adverse events, whereas the placebo group had 6 serious adverse events and 12 other adverse events. Conclusions and Relevance: In this preliminary study of adult outpatients with symptomatic COVID-19, patients treated with fluvoxamine, compared with placebo, had a lower likelihood of clinical deterioration over 15 days. However, the study is limited by a small sample size and short follow-up duration, and determination of clinical efficacy would require larger randomized trials with more definitive outcome measures.

( Am J Obstet Gynecol . 2020;222:521–531) Caring for vulnerable populations is a critical component of pandemic management. Pregnant women are susceptible to respiratory illness with an increased infectious morbidity and mortality. While clinical information is limited on the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the pregnant population, both the SARS-CoV and MERS-CoV outbreaks of the last 2 decades resulted in approximately one third of infected pregnant women dying from the illness. The purpose of this paper was to summarize the clinical features of coronavirus disease 2019 (COVID-19) in pregnant women, and present a pragmatic and integrated framework for handling complex intricacies involved in disease management.

BACKGROUND: An antimicrobial stewardship program (ASP) is one of the core elements needed to optimize antimicrobial use. Although collaboration at the national level to address the importance of ASPs and antimicrobial resistance has occurred in the Asia Pacific region, hospital-level ASP implementation in this region has not been comprehensively evaluated. METHODS: We conducted a systematic review and meta-analysis to assess the efficacy of ASPs in inpatient settings in the Asia Pacific region from January 2005 through March 2016. The impact of ASPs on various outcomes, including patient clinical outcomes, antimicrobial prescription outcomes, microbiological outcomes, and expenditure were assessed. RESULTS: Forty-six studies were included for a systematic review and meta-analysis. The pooled risk ratio for mortality from ASP before-after trials and 2-group comparative studies were 1.03 (95% confidence interval [CI], .88-1.19) and 0.69 (95% CI, .56-.86), respectively. The pooled effect size for change in overall antimicrobial and carbapenem consumption (% difference) was -9.74% (95% CI, -18.93% to -.99%) and -10.56% (95% CI, -19.99% to -3.03%), respectively. Trends toward decreases in the incidence of multidrug-resistant organisms and antimicrobial expenditure (range, 9.7%-58.1% reduction in cost in the intervention period/arm) were also observed. CONCLUSIONS: ASPs in inpatient settings in the Asia Pacific region appear to be safe and effective to reduce antimicrobial consumption and improve outcomes. However, given the significant variations in assessing the efficacy of ASPs, high-quality studies using standardized surveillance methodology for antimicrobial consumption and similar metrics for outcome measurement are needed to further promote antimicrobial stewardship in this region.

BACKGROUND: The symptoms of coronavirus disease 2019 (COVID-19) appear to be heterogenous, and the typical course of these symptoms is unknown. Our objectives were to characterize the common trajectories of COVID-19 symptoms and to assess how symptom course predicts other symptom changes as well as clinical deterioration. METHODS: One hundred sixty-two participants with acute COVID-19 responded to surveys up to 31 times for up to 17 days. Several statistical methods were used to characterize the temporal dynamics of these symptoms. Because 9 participants showed clinical deterioration, we explored whether these participants showed any differences in symptom profiles. RESULTS: Trajectories varied greatly between individuals, with many having persistently severe symptoms or developing new symptoms several days after being diagnosed. A typical trajectory was for a symptom to improve at a decremental rate, with most symptoms still persisting to some degree at the end of the reporting period. The pattern of symptoms over time suggested a fluctuating course for many patients. Participants who showed clinical deterioration were more likely to present with higher reports of severity of cough and diarrhea. CONCLUSIONS: The course of symptoms during the initial weeks of COVID-19 is highly heterogeneous and is neither predictable nor easily characterized using typical survey methods. This has implications for clinical care and early-treatment clinical trials. Additional research is needed to determine whether the decelerating improvement pattern seen in our data is related to the phenomenon of patients reporting long-term symptoms and whether higher symptoms of diarrhea in early illness presages deterioration.
