Project description:Clinical efficacy of remdesivir in children with COVID-19 is unclear. This propensity-score-matched retrospective cohort study of children with COVID-19 showed that the rate of patients achieving defervescence on Day 4 was higher in the remdesivir group than in the non-remdesivir group, but was not statistically different (86.7% vs 73.3%, P = 0.333).

Project description:While the relative efficacy of remdesivir as a therapeutic agent in selected patients with COVID-19 has been established, safety concerns have been raised regarding potential nephrotoxicity and hepatotoxicity. Our main objective was to investigate the kidney- and liver-related safety outcomes in patients with COVID-19 treated with remdesivir in a public hospital in New York. A propensity score-matched retrospective study was conducted in hospitalized patients with COVID-19 from 1 June 2020 to 10 March 2021. A total of 927 patients were included in this study (remdesivir: 427, non-remdesivir: 500; women: 51.8%; median age 61 years; median BMI: 28.5 kg/m2). Matching without replacement yielded a cohort of 248 patients (124 in each group). In the matched cohort, the remdesivir group had a significantly lower rate of acute kidney injury (AKI) (12.1% vs. 21.8%, p = 0.042), a lower rate of acute liver injury (ALI) on the verge of statistical significance (7.3% vs. 14.5%, p = 0.067), and non-significantly lower death rate (13.7% vs. 16.1%, p = 0.593) compared to the non-remdesivir group. Multivariable analyses revealed that patients treated with remdesivir were found to be associated with a significantly lower likelihood for AKI (OR: 0.40; 95% CI: 0.24-0.67, p < 0.001), no association was found for ALI (OR: 0.68; 95% CI: 0.35-1.30, p = 0.241), while a trend towards an association of patients treated with remdesivir with a lower likelihood for in-hospital death was observed (OR: 0.57; 95% CI: 0.32-1.01, p = 0.053). In conclusion, no safety concerns with regards to renal and liver outcomes were raised in patients with COVID-19 treated with remdesivir. Instead, there were signals of possible nephroprotection and improved in-hospital mortality.

Project description:As a traditional Chinese medicine, Lianhua Qingwen capsules have been widely used to treat Coronavirus Disease 2019 (COVID-19). This study was aimed to demonstrate the association between treatment with Lianhua Qingwen capsules and the clinical outcomes of hospitalized patients with COVID-19. This retrospective study was conducted at four hospitals in Central China. Data of hospitalized COVID-19 patients were collected between December 19, 2019 and April 26, 2020. Based on whether Lianhua Qingwen capsules were used, patients were classified into Lianhua Qingwen and non-Lianhua Qingwen (control) groups. To control for confounding factors, we used conditional logistic regression in a propensity-score matched (PSM) cohort (1 : 1 balanced), as well as logistic regression without matching as sensitivity analysis. A total of 4918 patients were included, 2760 of whom received Lianhua Qingwen capsules and 2158 of whom did not. In the PSM model, after adjusting for confounders, the in-hospital mortality was similar between the Lianhua Qingwen group and the control group (6.8% vs. 3.3%, adjusted OR, 0.66 [95% CI, 0.38-1.15], p = 0.138). The negative conversion rate of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection was higher in the Lianhua Qingwen group (88.3% vs. 96.1%, adjusted OR, 4.02 [95% CI, 2.58-6.25], p < 0.001). The incidence of acute liver injury was comparable between the two groups (14.0% vs. 11.5%, adjusted OR: 0.85 [95% CI, 0.71-1.02], p = 0.083), and the incidence of acute kidney injury was lower in the Lianhua Qingwen group (5.3% vs. 3.0%, adjusted OR: 0.71 [95% CI, 0.50-1.00], p = 0.048). Treatment with Lianhua Qingwen capsules was not significantly associated with in-hospital mortality in COVID-19 patients. In the Lianhua Qingwen group, the negative conversion rate of SARS-CoV-2 infection was higher and the incidence of acute kidney injury was lower than in the control group.

Project description:BackgroundRemdesivir is the only antiviral agent approved for the treatment of hospitalized coronavirus disease 2019 (COVID-19) patients requiring supplemental oxygen. Studies show conflicting results regarding its effect on mortality.MethodsIn this single center observational study, we included adult hospitalized COVID-19 patients. Patients who were treated with remdesivir were compared to controls. Remdesivir was administered for 5 days. To adjust for any imbalances in our cohort, a propensity score matched analysis was performed. The aim of our study was to analyze the effect of remdesivir on in-hospital mortality and length of stay (LOS).ResultsAfter propensity score matching, 350 patients (175 remdesivir, 175 controls) were included in our analysis. Overall, in-hospital mortality was not significantly different between groups remdesivir 5.7% [10/175] vs. control 8.6% [15/175], hazard ratio 0.50, 95% confidence interval (CI) 0.22-1.12, p = 0.091. Subgroup analysis showed a significant reduction of in-hospital mortality in patients who were treated with remdesivir ≤ 7 days of symptom onset remdesivir 4.2% [5/121] vs. control 10.4% [13/125], hazard ratio 0.26, 95% CI 0.09 to 0.75, p = 0.012 and in female patients remdesivir 2.9% [2/69] vs. control 12.2% [9/74], hazard ratio 0.18 95%CI 0.04 to 0.85, p = 0.03. Patients in the remdesivir group had a significantly longer LOS (11 days vs. 9 days, p = 0.046).ConclusionRemdesivir did not reduce in-hospital mortality in our whole propensity score matched cohort, but subgroup analysis showed a significant mortality reduction in female patients and in patients treated within ≤ 7 days of symptom onset. Remdesivir may reduce mortality in patients who are treated in the early stages of illness.

Project description:BackgroundRemdesivir is not currently approved for patients with eGFR <30 ml/min per 1.73 m2. We aimed to determine the safety of remdesivir in patients with kidney failure.MethodsThis study was a retrospective cohort study of patients with COVID-19 hospitalized between May 2020 and January 2021 with eGFR <30 ml/min per 1.73 m2 who received remdesivir and historical controls with COVID-19 hospitalized between March 1, 2020 and April 30, 2020 prior to the emergency use authorization of remdesivir within a large health care system. Patients were 1:1 matched by propensity scores accounting for factors associated with treatment assignment. Adverse events and hospital outcomes were recorded by manual chart review.ResultsThe overall cohort included 34 hospitalized patients who initiated remdesivir within 72 hours of hospital admission with eGFR<30 ml/min per 1.73 m2 and 217 COVID-19 controls with eGFR <30 ml/min per 1.73 m2. The propensity score-matched cohort included 31 remdesivir-treated patients and 31 nonremdesivir-treated controls. The mean age was 74.0 (SD=13.8) years, 57% were women, and 68% were white participants. A total of 26% had ESKD. Among patients who were not on dialysis prior to initiating remdesivir, one developed worsening kidney function (defined as ≥50% increase in creatinine or initiation of KRT) compared with three in the historical control group. There was no increased risk of cardiac arrythmia, cardiac arrest, altered mental status, or clinically significant anemia or liver function test abnormalities. There was a significantly increased risk of hyperglycemia, which may be partly explained by the increased use of dexamethasone in the remdesivir-treated population.ConclusionsIn this propensity score-matched study, remdesivir was well tolerated in patients with eGFR <30 ml/min per 1.73 m2.

Project description:The aim of this study was to compare the estimated blood loss and the frequency of obstetric hemorrhage among pregnant women with and without COVID-19 infection. The study was carried out in the Department of Obstetrics and Gynecology, at the Central Clinical Hospital of the Ministry of the Interior and Administration in Warsaw, Poland. From 15 May 2020 to 26 April 2021, a total of 224 parturients with COVID-19 infection were admitted for labor. The control group consisted of 300 randomly recruited pre-pandemic deliveries that took place between 15 May 2019 and 26 April 2020 at the Department. The primary outcome was the presence of postpartum hemorrhage, defined as an estimated blood loss of ≥500 mL within 24 h after birth or the need to transfuse 2 or more units of packed red blood cells (pRBCs). Secondary outcomes were the difference between hemoglobin and hematocrit levels at 24 h postpartum, the number of pRBCs units transfused, and the need for transperitoneal drainage. After applying the propensity-score-matching procedure for postpartum bleeding risk factors, 325 eligible patients were included in the final analysis, divided into 203 COVID-19 positive and 122 COVID-19 negative prepandemic deliveries. SARS-CoV-2 infected patients were characterized by a longer activated partial thromboplastin time (APTT), a reduced prothrombin time (PT), and lower platelet count at initial presentation. COVID-19 deliveries were found to be associated with a higher frequency of postpartum hemorrhage, an increased estimated blood loss, the more frequent use of peritoneal drainage, and more pRBCs units transfused. During the pandemic, an increased risk of postpartum hemorrhage posed another threat to SARS-CoV-2 infected pregnant women. It is essential to be aware of this when approaching COVID-19 delivery and to implement efficient preventative methods.

Project description:BackgroundTixagevimab and Cilgavimab, a combined monoclonal antibody (Evusheld) was granted emergency use authorization for SARS-CoV-2 preexposure prophylaxis in individuals with moderate to severe immunocompromising condition. In this study we used population-based real-world data to evaluate the effectiveness of Evusheld in immunocompromised patients.MethodsUsing the computerized database of the largest healthcare provider in Israel, we identified all adult immunocompromised patients who were eligible to receive Evusheld (the dose used during the study period was 150 mg Tixagevimab and 150 mg Cilgavimab) on 15-February-2022. Patients with a documentation of a prior SARS-CoV-2 infection were excluded. A total of 703 patients who received Evusheld were propensity score-matched, using a ratio of 1:4, with 2812 patients who have not received Evusheld (control group). Patients were followed through 30-June-2022 for up to 90-days for the first documentation of SARS-CoV-2 infection and COVID-19 related hospitalization.ResultsOverall, 72 patients in the Evusheld group and 377 patients in the control group had SARS-CoV-2 infection, reflecting and incidence rate of 4.18 and 5.64 per 100 person-months, respectively. HR was 0.75(95%CI,0.58-0.96) for SARS-CoV-2 infection, and 0.41(0.19-0.89) for COVID-19 related hospitalization in the Evusheld group compared to the control group. The magnitude of relative risks reduction of each outcome was greater in non-obese patients (P for interaction = 0.020 and 0.045, respectively).ConclusionThis study suggests that Evusheld (150 mg Tixagevimab and 150 mg Cilgavimab) is effective in reducing the risk of SARS-CoV-2 infection and COVID-19 hospitalization in immunocompromised patients. The effectiveness of this dose appears to be greater in non-obese patients.

Project description:IntroductionRemdesivir is a registered treatment for hospitalised patients with COVID-19 that has moderate clinical effectiveness. Anecdotally, some patients' respiratory insufficiency seemed to recover particularly rapidly after initiation of remdesivir. In this study, we investigated if this rapid improvement was caused by remdesivir, and which patient characteristics might predict a rapid clinical improvement in response to remdesivir.MethodsThis was a multicentre observational cohort study of hospitalised patients with COVID-19 who required supplemental oxygen and were treated with dexamethasone. Rapid clinical improvement in response to treatment was defined by a reduction of at least 1 L of supplemental oxygen per minute or discharge from the hospital within 72 h after admission. Inverse probability of treatment-weighted logistic regression modelling was used to assess the association between remdesivir and rapid clinical improvement. Secondary endpoints included in-hospital mortality, ICU admission rate and hospitalisation duration.ResultsOf 871 patients included, 445 were treated with remdesivir. There was no influence of remdesivir on the occurrence of rapid clinical improvement (62% vs 61% OR 1.05, 95% CI 0.79-1.40; p = 0.76). The in-hospital mortality was lower (14.7% vs 19.8% OR 0.70, 95% CI 0.48-1.02; p = 0.06) for the remdesivir-treated patients. Rapid clinical improvement occurred more often in patients with low C-reactive protein (≤ 75 mg/L) and short duration of symptoms prior to hospitalisation (< 7 days) (OR 2.84, 95% CI 1.07-7.56).ConclusionRemdesivir generally does not increase the incidence of rapid clinical improvement in hospitalised patients with COVID-19, but it might have an effect in patients with short duration of symptoms and limited signs of systemic inflammation.
