NAT2 Slow Acetylator Phenotype as a Significant Risk Factor for Hepatotoxicity Caused by Antituberculosis Drugs: Results From a Multiethnic Nested Case-Control Study.

Background: Under standard therapies, the incidence of drug-induced liver injury (DILI) in patients with tuberculosis ranges from 2% to 28%. Numerous studies have identified the risk factors for antituberculosis DILI; however, none have been conducted in a multiethnic real-world setting. The primary outcome of the current study was to identify the risk factors that could be used as the best predictors of DILI in a multiethnic cohort.

Burden and Risk Factors for Coinfections in Patients with a Viral Respiratory Tract Infection.

Which patients should be monitored for coinfections or should receive empirical antibiotic treatment, in patients with an acute viral respiratory infection, is largely unknown. We evaluated the prevalence, characteristics, outcomes of coinfected patients, and risk factors associated with a coinfection among patients with an acute viral infection. A retrospective, single-center study recruited consecutive patients from October 2022 to March 2023 presenting to the emergency department with signs of a respiratory tract infection.

Comparing the long-term effectiveness and safety of dolutegravir/lamivudine versus bictegravir/emtricitabine/tenofovir alafenamide fumarate as first-line regimens: a real life multicentre cohort.

Objectives: We compared the effectiveness and safety of bictegravir/emtricitabine/tenofovir alafenamide fumarate (BIC/FTC/TAF) and dolutegravir plus lamivudine (DTG + 3TC) in our cohort of treatment-naive people with HIV (PWH).

Methods: In a multicentre cohort of treatment-naive PWH starting a first-line regimen with either dolutegravir plus lamivudine or BIC/FTC/TAF, Kaplan-Meier survival analysis was used to estimate time to virological failure (VF) and time to treatment discontinuation (TD), whereas Cox regression was used to evaluate predictors of VF and TD. Changes in CD4+ cell count were assessed via non-parametric tests, and linear regression analyses were performed to explore predictors of CD4+ cell count changes.

Navigating Uncertainty: Managing Influenza-Associated Invasive Pulmonary Aspergillosis in an Intensive Care Unit.

We present a challenging case of a patient admitted to an intensive care unit with influenza-associated pulmonary aspergillosis (IAPA). The clinical course was characterised by refractory fungal pneumonia and tracheobronchitis, suspected drug-induced liver injury due to triazole antifungals, and secondary bacterial infections with multidrug-resistant microorganisms, resulting in a fatal outcome despite the optimisation of antifungal treatment through therapeutic drug monitoring. This case underscores the complexity that clinicians face in managing critically ill patients with invasive fungal infections.

The Case of Dolutegravir Plus Darunavir Antiretroviral Regimens: Is It Always Useful to Double the Drug Doses? A Short Communication.

Background: Antiretroviral drug combinations affect dolutegravir trough concentrations. Here, the authors focused on dolutegravir plus booster darunavir antiretroviral regimens to investigate the effect of the booster and/or timing of drug administration on dolutegravir and darunavir plasma trough concentrations.

Methods: This retrospective observational study included consecutive people with HIV (PWH) receiving dolutegravir plus booster darunavir antiretroviral regimens for at least 3 months, with at least one assessment of dolutegravir and darunavir plasma trough concentrations.

Anal HPV prevalence in individuals with and without other concomitant sexually transmitted infections.

The association between human papillomavirus (HPV) and other sexually transmitted infections (STIs) in anal lesions still remains unclear. Aim of the study was to evaluate the prevalence of simultaneous infection of HPV and Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and Trichomonas vaginalis in individuals screened for HPV anal infection. A total of 507 anal samples were tested for both anal HPV and STIs: 16% resulted positive for one or more non-HPV STIs.

Mismanagement of SARS-CoV-2 Infection Pre Hospitalisation during the Omicron Era: Antibiotics and Steroids Instead of Early Antivirals.

The aim of this study was to assess the prevalence of inappropriate treatment among hospitalised patients affected by SARS-CoV-2 infection before hospital admission during the Omicron era. This single-centre, retrospective observational study included all the patients hospitalised because of SARS-CoV-2 infection during three periods characterised by the Italian prevalence of an Omicron variant of concern: (1) January-May 2022 (BA.1-BA.

Impact of a Bundle of Interventions on Quality-of-Care Indicators for Bacteraemia: A Single-Centre, Quasi-Experimental, Before-After Study.

bacteraemia (SAB) is a life-threatening bloodstream infection. Improved adherence to quality-of-care indicators (QCIs) can significantly enhance patient outcomes. This quasi-experimental study evaluated the impact of a bundle of interventions on QCI adherence in adult patients with SAB.

How to manage adult patients with malaria in the non-endemic setting.

Background: The diagnosis and management of malaria in non-endemic countries presents a continuing challenge. Plasmodium falciparum, which is capable of rapidly inducing severe and life-threatening multiorgan disease, is the species most frequently diagnosed in Europe and North America.

Objectives: To summarise the more relevant diagnostic findings and clinical features of malaria observed in non-endemic settings and to provide an update of the key management decision points using three illustrative clinical scenarios of uncomplicated and severe malaria.

Hospital-Based Influenza and Pneumococcal Vaccination for Cancer Patients on Active Treatment and Their Family Members during the COVID-19 Pandemic in Italy: A Single-Center Experience.

In patients with cancer, tumor- and treatment-induced immunosuppression are responsible for a four-fold increase in morbidity and mortality caused by influenza and invasive infections compared to the general population. The main oncology societies strongly recommend vaccination in patients with cancer to prevent these infections. However, vaccine hesitancy is a main concern in this population.

Breakthrough Acute HIV Infections among Pre-Exposure Prophylaxis Users with High Adherence: A Narrative Review.

Pre-exposure prophylaxis (PrEP) is a pivotal intervention among HIV prevention strategies. We aimed to narratively revise the topic of HIV acute infection in the setting of PrEP exposure with a focus on diagnostic options, clinical features, and future PrEP perspectives, with a particular focus on users with high adherence to PrEP. We searched the main databases (PubMed, Embase, and Scopus) with the keywords "PrEP" or "Pre-Exposure Prophylaxis" and "HIV" or "PLWH" and "breakthrough" or "acute infection" or "primary infection".

Major Bleeding Events in Hospitalized COVID-19 Patients: A Retrospective Observational Study.

Thromboprophylaxis/anticoagulation treatment is often required in hospitalized COVID-19 patients. We aimed to estimate the prevalence of major bleeding events in hospitalized COVID-19 patients. This was a retrospective observational study including all COVID-19 hospitalized patients ≥18 years of age at one reference center in northern Italy.

Laryngeal Leishmaniasis: A Neglected, Emerging Disease in Northern Italy.

Leishmaniasis represents an emerging public health issue in Mediterranean countries. The incidence of this condition has progressively risen in Northern Italy due to the growing number of immunocompromised people and probably due to climate changes. We hereby describe a case of relapsing laryngeal leishmaniasis in a female immunocompetent patient, presenting as aspecific chronic laryngitis.

Prognostic Significance of NLR and PLR in COVID-19: A Multi-Cohort Validation Study.

Introduction: Recent studies have highlighted the prognostic value of easily accessible inflammatory markers, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) for predicting severe outcomes in patients affected by Coronavirus disease 2019 (COVID-19). Our study validates NLR and PLR cut-off values from a prior cohort at IRCCS Policlinico San Matteo (OSM) of Pavia, Italy, across two new cohorts from different hospitals. This aims to enhance the generalizability of these prognostic indicators.

The WHO fungal priority pathogens list: a crucial reappraisal to review the prioritisation.

In October, 2022, WHO published the first fungal priority pathogen list, which categorised 19 fungal entities into three priority groups (critical, high, and medium), for prioritisation of research efforts. The final ranking was determined via multiple criteria decision analysis, considering both research and development needs and perceived public health importance. In this Personal View, we discuss the positioning of the fungal pathogens, namely, Mucorales, Candida spp, Histoplasma spp, Coccidioides and Paracoccidioides spp, Fusarium spp, eumycetoma causative agents, Talaromyces marneffei, and Pneumocystis jirovecii, while expressing concerns about potential disparities between the WHO fungal priority pathogen list ranking and the actual disease burden associated with these pathogens.

Evaluation of analytical performance of the STANDARD M10 MPX/OPX assay for the simultaneous DNA detection and clade attribution of .

(MPXV) infection confirmation needs reliable polymerase chain reaction (PCR) assays; in addition, viral clade attribution is a key factor in containment measures, considering a more severe syndrome in clade I and the possibility of simultaneous circulation. This study evaluates the performance of all-in-one STANDARD M10 MPX/OPX (SD BIOSENSOR, South Korea - M10). Frozen samples from 205 subjects were selected and stratified according to routine test results (RealStar® Orthopoxvirus PCR Kit 1.
