RESUMO
OBJECTIVES: 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. METHODS: Interferon-α/γ (IFN-α/IFN-γ) serum levels, neutralizing antibodies and RNAemia at COVID-19 diagnosis, and persistent RNAemia during the follow-up were evaluated. RESULTS: 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. CONCLUSION: 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.

Objective: To analyze the availability and access to the hospital for the patients with intra-abdominal infections (IAIs) by Escherichia coli (E. coli) as a result of the coronavirus disease 2019 (COVID-19) pandemic and the impact of these changes in the diagnosis and their effects on the death of these patients. Methods: Two prospective observational cohorts of the patients with IAI by E. coli were conducted in 2016 (the pre-COVID-19, n = 108) and in 2020 (during the COVID-19, n = 96) at the University Hospital of Seville, Spain. The demographic and clinical variables of the patients were collected and analyzed. The patients were followed-up for 120 days, until the hospital discharge or death. The bivariate and multivariate analyses were performed. Results: Both the cohorts were homogeneous according to age, sex, emergency surgery cause, immunosuppression, neutropenia, acquisition type, and previous intervention. The patients attended during the COVID-19 had significantly higher Charlson comorbidity index and the more McCabe score, required more emergency surgery, had more severe infections with the higher rates of septic shock and sepsis, and the presence of additional care support such as a nasogastric tube. They were diagnosed later; the time intervals between the symptoms onset (SO) to the first medical contact or surgical intervention (SI) and between the first medical contact to the admission or SI were significantly higher. The death rates during the COVID-19 and the pre-COVID-19 were 16.7 and 6.5%, respectively (p = 0.02). Finally, the multivariate analysis in both the cohorts together identified the patients diagnosed during the COVID-19, the longer period from SO to SI, septic shock, and the Charlson comorbidity index as the independent factors associated with death. Conclusion: This study showed the impact of the COVID-19 pandemic on the clinical outcome and death due to IAI with an extension of the time between SO and SI.
RESUMO
INTRODUCTION: Outpatient parenteral antimicrobial therapy (OPAT) has been recognised as a useful, cost-effective and safe alternative to inpatient treatment. Nevertheless, the most common antimicrobials used are antibiotics, and there is less information about the use of antifungal therapy (AT). The aim of this study is to analyse a cohort of patients treated with AT administered via OPAT and to compare them with patients from the rest of the cohort (RC) treated with antibiotics. METHODS: Prospective observational study with post hoc (or retrospective) analysis of a cohort of patients treated in the OPAT program. We selected the patients treated with antifungals between July 2012 and December 2018. We recorded demographic and clinical data to analyse the validity of the treatment and to compare the differences between the AT and the RC. RESULTS: Of the 1101 patients included in the OPAT program, 24 (2.18%) were treated with AT, 12 Liposomal Amphotericin B, 6 echinocandins and 6 fluconazole. This result is similar to other cohorts. There were differences between the AT vs RC in the number of patients with neoplasia (58.3% vs 28%; p=0.001), IC Charlson>2 (58.3% vs 38.8; p=0.053), duration of treatment (15 days vs 10.39 days; p=0.001) and patients with central catheters (54.2% vs 21.7%; p=0.0001). These differences are justified because there were more hematologic patients included in the AT group. Nevertheless, there were no differences in adverse reactions (25% vs 32.3%; p=0.45) or re-admissions (12.5% vs 10%; p=0.686) and OPAT with AT was successful in 21/24 patients (87.5%). CONCLUSIONS: AT can be successfully administered in OPAT programs in selected patients, that are clinically stable and monitored by an infectious disease physician.
