Background There is an urgent need to reduce mortality of COVID-19. We examined if corticosteroids and tocilizumab reduce risk for death in patients with severe pneumonia caused by SARS-CoV-2. Methods A retrospective cohort study was performed in a single university hospital. All adult patients admitted with confirmed severe COVID-19 pneumonia from 9 March to 9 April 2020 were included. Severe pneumonia was defined as multi-lobar or bilateral pneumonia and a ratio of oxygen saturation by pulse oximetry to the fraction of inspired oxygen (SpFi)<315. All patients received antiviral and antibiotic treatment. From March 26, patients also received immunomodulatory treatment with corticosteroids (methylprednisolone 250 mg/day for 3 days), or tocilizumab or both. In-hospital mortality in the entire cohort and in a 1:1 matched cohort sub-analysis was evaluated. Results 255 patients were included, 118 received only antiviral and antibiotic treatment while 137, admitted after March 26, also received immunomodulators. In-hospital mortality of patients on immunomodulatory treatment was significantly lower than in those without [47/137(34.3%) vs. 69/118(58.5%), ( p < .001)]. The risk of death was 0.44 (CI, 0.26–0.76) in patients receiving corticosteroids alone and 0.292 (CI, 0.18–0.47) in those treated with corticosteroids and tocilizumab. In the sub-analysis with 202 matched patients, the risk of death was 0.356 (CI 0.179–0.707) in patients receiving corticosteroids alone and 0.233 (0.124–0.436) in those treated with the combination. Conclusions Combined treatment with corticosteroids and tocilizumab reduced mortality with about 25% in patients with severe COVID-19 pneumonia. Corticosteroids alone also resulted in lower in-hospital mortality rate compared to patients receiving only antiviral and antibiotic treatment. Corticosteroids alone or combined with tocilizumab may be considered in patients with severe COVID-19 pneumonia.

Home intravenous antibiotic therapy is an alternative to hospital admission for moderately severe infections. However, few studies have analyzed its safety and effectiveness in the treatment of infections caused by multidrug-resistant bacteria. The purpose of this study is to analyze the safety and effectiveness of home intravenous antibiotic therapy in multidrug-resistant bacterial infections. We analyzed prospectively all patients admitted to our service who underwent home intravenous antibiotic therapy during the period 2008-2012. All the treatments were administered by caretakers or self-administered by patients, through elastomeric infusion devices. Effectiveness was evaluated by analyzing the readmission rate for poor infection control. Safety was evaluated by analyzing adverse events, catheter-related complications, and readmissions not related to poor infection control. There were 433 admissions (in 355 patients) for home intravenous antibiotic therapy during the study period. There were 226 (52.2 %) admissions due to multidrug-resistant bacterial infections and 207 (47.8 %) due to non-multidrug-resistant infections. Hospital readmissions in patients with multidrug-resistant infections were uncommon. Multidrug-resistant enterococcal infections, healthcare-associated infections, and carbapenem therapy were independent variables associated with increased readmissions due to poor infection control. Readmissions not related to poor infection control, adverse events, and catheter-related complications were similar in multidrug-resistant compared to non-multidrug-resistant bacterial infections. Home intravenous therapy, administered by patients or their caretakers using elastomeric infusion pumps, was safe and effective for the treatment of most multidrug-resistant bacterial infections.
