    Abstract Purpose: Real-world experience with meropenem/vaborbactam (M/V) is limited. Our aim is to report a clinical experience of M/V in the treatment of resistant Gram-negative bacilli.
    Methods: This is a prospective observational study including patients hospitalized in the University Hospital of Pisa (March 2021-Jan 2023) with infections by both extended-spectrum β-lactamases (ESBL)-producing Enterobacterales and carbapenem-resistant Klebsiella pneumoniae (Kp) treated with M/V. The primary outcome measure was clinical success, defined as a composite of survival, resolution of signs and symptoms and absence of microbiological failure at day 30 from infection onset. A multivariable regression analysis was performed to identify factors associated with clinical failure. Odds ratio (OR) with 95% confidence intervals (CI) was calculated.
    Results: A total of 104 patients who received M/V were included: 24/104 (23.1%) infections were caused by ESBL non-hypervirulent Enterobacterales, 17/104 (16.3%) by ESBL-producing hypervirulent Klebsiella pneumoniae (hvKp) and 63/104 (60.6%) by CRE. The most common infections were bloodstream infections, followed by urinary tract infections, hospital-acquired pneumonia, intra-abdominal infections and others. Septic shock occurred in 16/104 (15.4%) patients. Clinical success was achieved in 77% of patients, and 30-day mortality rate was 15.4%. In patients with KPC-producing Kp infections, clinical success and 30-day mortality rates were 82% and 11.5%, respectively. On multivariable analysis, SOFA score (OR 1.32, 95% CI 1.02-1.7, p=0.032) was independently associated with clinical failure, while source control (OR 0.16, 95% CI 0.03-0.89, p=0.036) was protective.
    Conclusions: M/V is a promising therapeutic option against infections caused by difficult-to-treat ESBL-producing Enterobacterales and CR-Kp.

    Abstract Background: Metallo-β-lactamases (MBL)-producing Enterobacterales are increasing worldwide. Our aim was to describe clinical features, treatments and outcomes of infections by MBL-Enterobacterales.
    Methods: Prospective observational study conducted in the Pisa University Hospital (Jan 2019-Oct 2022) including patients with MBL-producing Enterobacterales infections. The primary outcome measure was 30-day mortality. A multivariable Cox regression analysis was performed to identify factors associated with 30-day mortality. Adjusted hazard ratio (aHR) (95% confidence intervals, CI) were calculated.
    Results: 343 patients were included: 15 VIM- and 328 NDM-producing Enterobacterales infections. Overall, 199 (58%) were bloodstream infections, 60 (17.5%) hospital-acquired/ventilator-associated pneumonias, 60 (17.5%) complicated urinary tract infections, 13 (3.8%) intra-abdominal infections, 11 (3.2%) skin and soft tissue infections. Thirty-day mortality was 29.7%. Thirty-two patients did not receive in vitro active antibiotic therapy, 215/343 (62.7%) received ceftazidime-avibactam (CZA) plus aztreonam (ATM), 33/343 (9.6%) cefiderocol-containing regimens, 26/343 (7.6%) colistin-containing regimens and 37 (10.8%) other active antibiotics. On multivariable analysis, septic shock (aHR 3.57, 95% CI 2.05-6.23, p<0.001) and age (aHR 1.05, 95% CI 1.03-1.08, p<0.001) were independently associated with 30-day mortality, while in vitro active antibiotic therapy within 48 hours from infection (aHR 0.48, 95% CI 0.26-0.8, p=0.007) and source control (aHR 0.43, 95% CI 0.26-0.72, p=0.001) were protective factors. Sensitivity analysis showed that CZA plus ATM compared to colistin was independently associated with reduced 30-day mortality (aHR 0.39, 95% CI 0.18-0.86, p=0.019). Propensity score analyses confirmed these findings.
    Conclusions: MBL-CRE infections are associated with high 30-day mortality rates. Patients with MBL-producing Enterobacterales infections should received early active antibiotic therapy.

    Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related disease (COVID-19) has spread pandemically with high rates of morbidity and mortality. COVID-19 has also posed unprecedented challenges in terms of rapid development of pharmacological countermeasures to prevent or contrast SARS-CoV-2 pathogenicity. Anti-SARS-CoV-2 antiviral agents and monoclonal antibodies have been specifically designed to attenuate COVID-19 morbidity and prevent mortality in vulnerable subjects, such as patients with immune-mediated diseases, but evidence for the safe and effective use of these drugs in this latter population group is scarce. Therefore, we designed a retrospective, multicentre, observational, case-control study to analyse the impact of these treatments in COVID-19 patients with systemic lupus erythematosus (SLE), a paradigmatic, multi-organ autoimmune disease. We identified 21 subjects treated with antivirals and/or monoclonal antibodies who were matched with 42 untreated patients by age, sex, SLE extension and duration. Treated patients had higher baseline SLE disease activity index 2000 scores [SLEDAI-2K median (interquartile range) = 4 (1-5) vs. 0 (0-2);

    Abstract Purpose: COVID-19 displays a variety of clinical manifestations; in pauci-symptomatic patients olfactory (OD) and gustatory dysfunctions (GD) may represent the first or only symptom. This topic is currently arousing great interest, and a growing number of papers are being published. Aim of this study is to investigate the timing of recovery from OD and GD in a real-life population hospitalized for COVID-19.
    Methods: We followed up by a phone interview the first 100 patients discharged a month earlier from three Italian non-intensive care wards.
    Results: All 100 patients were Caucasian, mean age was 65 years, 60% were males. Forty-two patients (mean age 63 years) experienced subjective chemosensory dysfunctions (29 OD and 41 GD): the male/female ratio was 2:1; 83% reported a complete or near complete recovery at follow-up. The recovery rate was not significantly different between males and females. The mean duration of OD and GD was 18 and 16 days, respectively. The mean recovery time from OD or GD resulted significantly longer for females than for males (26 vs 14 days, P = 0.009). Among the 42 symptomatic, the mean age of males was significantly higher than that of females (66 vs 57 years, P = 0.04), while the opposite was observed in the 58 asymptomatic patients (60 vs 73 years, P = 0.0018).
    Conclusions: Recovery from OD or GD was rapid, occurring within 4 weeks in most patients. Chemosensory dysfunctions in women was less frequent, but longer lasting. The value of our study is its focus on a population of hospitalized patients significantly older than those previously described, and the additional data on gender differences.
