Purpose of reviewThe aim of this article is to review skin and soft tissue infections due to rapidly growing mycobacteria (RGM), with a particular focus on recently published literature (2021-2022).Recent findingsRGM are increasingly reported as a cause of skin and soft tissue infections, both in the community setting and as a cause of...

IntroductionInfluenza affects individuals of all ages and poses a significant threat during pandemics, epidemics, and sporadic outbreaks. Neuraminidase inhibitors (NAIs) are currently the first choice in the treatment and prevention of influenza, but their use can be hindered by viral resistance.Areas coveredThis review summarizes current NAIs...

The rising incidence of bloodstream infections (BSI) due to Gram-negative bacteria (GNB) with difficult-to-treat resistance (DTR) has been recognized as a global emergency. The aim of this review is to provide a comprehensive assessment of the mechanisms of antibiotic resistance, epidemiology and treatment options for BSI caused by GNB with...

We describe a case of Buruli ulcer diagnosed by tissue culture and PCR in a Caucasian male returning from Madagascar where he served as a health-care worker in the Antsiranana region. To the best of our knowledge, this could be the first case of Mycobacterium ulcerans infection reported in Madagascar.

Introduction Candida auris is responsible for hospital outbreaks worldwide. Some C. auris isolates may show concomitant resistance to azoles, echinocandins, and polyenes, thereby possibly leaving clinicians with few therapeutic options. Areas covered Antifungal agents both in early and in late phases of clinical development showing anti-C....

: Efficacy of early treatment with anti-SARS-CoV-2 spike protein monoclonal antibodies (mAbs) for nosocomial SARS-CoV-2 infection in hematologic patients is unknown. Retrospective, cohort study conducted in four Italian teaching hospitals. We included adult patients with hematologic malignancies and hospital-acquired SARS-CoV-2 infection...

COVID-19 in immunocompromised patients is difficult to treat. SARS-CoV-2 interaction with the host immune system and the role of therapy still remains only partly understood. There are no data regarding the use of monoclonal antibodies and the combination of two antivirals in fighting viral replication and disease progression. We report the...

Background: In recent years, many aspects of the physiological role of PCSK9 have been elucidated, in particular regarding its role in lipid metabolism, cardiovascular risk but also its role in innate immunity. Increasing evidence is available on the involvement of PCSK9 in the pathogenesis of viral infections, mainly HCV, as well as in the...

Staphylococcus aureus remains an important human pathogen of concern, with mortality rates surpassing 30% in the case of severe systemic infections. Distinguishing methicillin-susceptible S. aureus from methicillin-resistant S. aureus (MRSA) is fundamental for therapeutic choices. A crucial emerging concept in the treatment of acute bacterial...

Objectives: The serum (1,3)-beta-D-glucan (BDG) assay gives quicker results and has higher sensitivity than blood cultures, therefore it is advised for early diagnosis of invasive candidemia and/or discontinuation of empirical therapy. Its sensitivity may depend on different factors. The aim of our study was to analyse the in vitro and in vivo...

Twenty-two immunocompromised patients with prolonged/relapsed COVID-19 received combination therapy with 2 antivirals (remdesivir + nirmatrelvir/ritonavir, n = 20; remdesivir + molnupiravir, n = 2) together with anti-spike monoclonal antibodies in 18. The response rate at day 14, day 30, and last follow-up was 75%, 73%, and 82%,...

Introduction: Candida auris (C. auris) is an emerging nosocomial pathogen, and a sharp rise in cases of colonization and infection has been registered in intensive care units (ICUs) during the ongoing coronavirus disease 2019 (COVID-19) pandemic. The unfavorable resistance profile of C. auris and the potential high mortality of C. auris...

Background: Immunocompromised patients show prolonged shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in nasopharyngeal swabs. We report a case of prolonged persistence of viable SARS-CoV-2 associated with clinical relapses of coronavirus disease 2019 (COVID-19) in a patient with mantle cell lymphoma who underwent...

Experience in real clinical practice with ceftazidime-avibactam for the treatment of serious infections due to gram-negative bacteria (GNB) other than carbapenem-resistant Enterobacterales (CRE) is very limited.

BACKGROUND: The primary objective of the study is to describe the cellular characteristics of bronchoalveolar lavage fluid (BALF) of COVID-19 patients requiring invasive mechanical ventilation; the secondary outcome is to describe BALF findings between survivors vs non-survivors.MATERIALS AND METHODS: Patients positive for SARS-CoV-2 RT PCR,...

Introduction: A lack of updated data on the burden and profile of anaerobic bloodstream infections (ABIs) exists. We assessed the incidence of ABIs and trends in antimicrobial resistance in anaerobes isolated from blood in Italy. Material and methods: We conducted a retrospective study on 17 Italian hospitals (2016-2020). Anaerobes isolated...

Coronavirus disease 2019 (COVID-19) can lead to respiratory failure due to severe immune response. Treatment targeting this immune response might be beneficial but there is limited evidence on its efficacy. The aim of this study was to determine if early treatment of patients with COVID-19 pneumonia with tocilizumab and/or steroids was...
