Background: Cancer-related fatigue (CRF) occurs in nearly all patients with metastatic breast cancer (MBC). Objectives: This real-world analysis aimed to describe the prevalence and importance of fatigue in patients with MBC within 3 months of treatment with single-agent taxane-based chemotherapy during the timeframe of 2020–2022 in the United States and Europe. It was also conducted to assess whether there was a difference in relapsed patients compared to patients diagnosed de novo . Design: Electronic health records were analyzed from approximately 150 million patients to identify patients with MBC who underwent taxane treatment. Results: In 2021, 50,490 patients had MBC, of whom 16,170 were diagnosed de novo and 34,330 experienced relapse. The proportion of patients undergoing taxane-based chemotherapy was 7.5% ( n = 1220) and 13.4% ( n = 4590), respectively, and the prevalence of any fatigue and CRF was similar between the groups (24.6% versus 25.7% and 6.6% versus 5.4%, respectively). Conclusion: At least one in four patients with MBC undergoing taxane-based treatment will experience fatigue. This highlights the importance of validating screening tools to identify CRF, which is necessary to advance clinical trials aimed at investigating treatment strategies to improve patient-centered outcomes for fatigue.

Abstract Introduction Polymorphonuclear cell influx into the interstitial and bronchoalveolar spaces is a cardinal feature of severe coronavirus disease 2019 (COVID-19), principally mediated by interleukin-8 (IL-8). We sought to determine whether reparixin, a novel IL-8 pathway inhibitor, could reduce disease progression in patients hospitalized with severe COVID-19 pneumonia. Methods In this Phase 3, randomized, double-blind, placebo-controlled, multicenter study, hospitalized adult patients with severe COVID-19 pneumonia were randomized 2:1 to receive oral reparixin 1200 mg three times daily or placebo for up to 21 days or until hospital discharge. The primary endpoint was the proportion of patients alive and free of respiratory failure at Day 28, with key secondary endpoints being the proportion of patients free of respiratory failure at Day 60, incidence of intensive care unit (ICU) admission by Day 28 and time to recovery by Day 28. Results Of 279 patients randomized, 182 received at least one dose of reparixin and 88 received placebo. The proportion of patients alive and free of respiratory failure at Day 28 was similar in the two groups {83.5% versus 80.7%; odds ratio 1.63 [95% confidence interval (CI) 0.75, 3.51]; p = 0.216}. There were no statistically significant differences in the key secondary endpoints, but a numerically higher proportion of patients in the reparixin group were alive and free of respiratory failure at Day 60 (88.7% versus 84.6%; p = 0.195), fewer required ICU admissions by Day 28 (15.8% versus 21.7%; p = 0.168), and a higher proportion recovered by Day 28 compared with placebo (81.6% versus 74.9%; p = 0.167). Fewer patients experienced adverse events with reparixin than placebo (45.6% versus 54.5%), most mild or moderate intensity and not related to study treatment. Conclusions This trial did not meet the primary efficacy endpoints, yet reparixin showed a trend toward limiting disease progression as an add-on therapy in COVID-19 severe pneumonia and was well tolerated.

Secondary bacterial infections and bacterial coinfections are an important complication of coronavirus disease 2019 (COVID-19), leading to antibiotic overuse and increased rates of antimicrobial resistance (AMR) during the COVID-19 pandemic. In this literature review, we summarize the reported rates of secondary bacterial infections and bacterial coinfections in patients with COVID-19, the impact on patient outcomes, the antibiotic treatment approaches employed, and the resistance patterns observed. The reported data suggest that although the incidence of secondary bacterial infections or bacterial coinfections is relatively low, they are associated with worse outcomes such as prolonged hospitalization, intensive care unit admission, mechanical ventilator use, and increased mortality. Interestingly, antibiotic prescription rates are typically higher than secondary bacterial and bacterial coinfection rates, and reports of AMR are common. These findings highlight the need for an improved understanding of secondary bacterial and bacterial coinfection in patients with COVID-19, as well as improved treatment options, to mitigate inappropriate antibiotic prescribing and AMR.
