During the COVID-19 pandemic, the implementation of antimicrobial stewardship strategies has been recommended. This study aimed to assess the impact of the COVID-19 pandemic in a tertiary care ...Spanish hospital with an active ongoing antimicrobial stewardship programme (ASP). For a 20-week period, we weekly assessed antimicrobial consumption, incidence density, and crude death rate per 1000 occupied bed days of candidemia and multidrug-resistant (MDR) bacterial bloodstream infections (BSI). We conducted a segmented regression analysis of time series. Antimicrobial consumption increased +3.5% per week (p = 0.016) for six weeks after the national lockdown, followed by a sustained weekly reduction of −6.4% (p = 0.001). The global trend for the whole period was stable. The frequency of empirical treatment of patients with COVID-19 was 33.7%. No change in the global trend of incidence of hospital-acquired candidemia and MDR bacterial BSI was observed (+0.5% weekly; p = 0.816), nor differences in 14 and 30-day crude death rates (p = 0.653 and p = 0.732, respectively). Our work provides quantitative data about the pandemic effect on antimicrobial consumption and clinical outcomes in a centre with an active ongoing institutional and education-based ASP. However, assessing the long-term impact of the COVID-19 pandemic on antimicrobial resistance is required.
•SARS-CoV-2 RNAemia in haematologic patients is associated with pneumonia.•SARS-CoV-2 RNAemia in haematologic patients is associated with disease severity.•COVID-19 haematologic patients require more ...frequently high-flow oxygen therapy.•Older age and persistent RNAemia are independent risk factors of mortality.
: Patients with haematologic malignancies (HM) COVID-19 have more severe disease, with increased risk of mortality. Therefore, this study aimed to evaluate the effect of SARS-CoV-2 RNAemia and the specific humoral immune responses on the clinical outcomes of patients with HM and COVID-19.
: Interferon-α/γ (IFN-α/IFN-γ) serum levels, neutralizing antibodies (NAb), and RNAemia at COVID-19 diagnosis, and persistent RNAemia during the follow-up were evaluated.
: Overall, 63 (58.9%) out of 107 patients had RNAemia, which was persistent in 26 (41.3%) patients. RNAemia at diagnosis and persistent RNAemia were associated with the need for high-flow nasal oxygen therapy during admission. Persistent RNAemia, age >70 years, and CURB-65 score ≥2 in patients with pneumonia were associated with increased 90-day mortality (p = 0.009, p = 0.030, and p = 0.001, respectively). The 90-day overall survival was lower (p = 0.006) in patients with persistent RNAemia. In addition, dexamethasone administration was associated with a COVID-19 episode with persistent RNAemia.
: Our results suggest that in patients with HM, RNAemia at the time of COVID-19 diagnosis and during the follow-up can be used to stratify patients with HM according to their clinical evolution and to guide clinical decisions tailored to the specific needs of each patient.
Abstract
The aim was to assess the ability of nasopharyngeal SARS-CoV-2 viral load at first patient’s hospital evaluation to predict unfavorable outcomes. We conducted a prospective cohort study ...including 321 adult patients with confirmed COVID-19 through RT-PCR in nasopharyngeal swabs. Quantitative Synthetic SARS-CoV-2 RNA cycle threshold values were used to calculate the viral load in log
10
copies/mL. Disease severity at the end of follow up was categorized into mild, moderate, and severe. Primary endpoint was a composite of intensive care unit (ICU) admission and/or death (n = 85, 26.4%). Univariable and multivariable logistic regression analyses were performed. Nasopharyngeal SARS-CoV-2 viral load over the second quartile (≥ 7.35 log
10
copies/mL,
p
= 0.003) and second tertile (≥ 8.27 log
10
copies/mL,
p
= 0.01) were associated to unfavorable outcome in the unadjusted logistic regression analysis. However, in the final multivariable analysis, viral load was not independently associated with an unfavorable outcome. Five predictors were independently associated with increased odds of ICU admission and/or death: age ≥ 70 years, SpO
2
, neutrophils > 7.5 × 10
3
/µL, lactate dehydrogenase ≥ 300 U/L, and C-reactive protein ≥ 100 mg/L. In summary, nasopharyngeal SARS-CoV-2 viral load on admission is generally high in patients with COVID-19, regardless of illness severity, but it cannot be used as an independent predictor of unfavorable clinical outcome.
