Clinical Microbiology, Virology and Bioemergency Diagnostics, ASST Fatebenefratelli Sacco, Luigi Sacco Hospital, Milan, Italy; Department of Biomedical and Clinical Sciences "L.Sacco", University of Milan, Italy.

Background: Mpox virus (MPXV) has recently spread outside of sub-Saharan Africa. This large multicentre study was conducted in Lombardy, the most densely populated Italian region accounting for more than 40% of Italian cases. The present study aims to: i) evaluate the presence and the shedding duration of MPXV DNA in different body compartments correlating the MPXV viability with the time to onset of symptoms; ii) provide evidence of MPXV persistence in different body compartment as a source of infection and iii) characterize the MPXV evolution by whole genome sequencing (WGS) during the outbreak occurred in Italy.

Background: Understanding the natural history of anal high-risk human papillomavirus (hrHPV) infection is key for designing anal cancer prevention programs but has not been systematically characterized.

Methods: We reanalyzed data from 34 studies including 16 164 individuals in 6 risk groups defined by human immunodeficiency virus (HIV) status, sex, and male sexuality: men who have sex with men (MSM) and people with HIV (MSMWH), HIV-negative MSM, women with HIV (WWH), HIV-negative women, men who have sex with women (MSW) with HIV (MSWWH), and HIV-negative MSW. We used Markov models to estimate incidence and clearance of 13 hrHPV types and their determinants.

Dysregulation in neutrophil extracellular trap (NET) formation and degradation may play a role in the pathogenesis and severity of COVID-19; however, its role in the pediatric manifestations of this disease, including multisystem inflammatory syndrome in children (MIS-C) and chilblain-like lesions (CLLs), otherwise known as "COVID toes," remains unclear. Studying multinational cohorts, we found that, in CLLs, NETs were significantly increased in serum and skin. There was geographic variability in the prevalence of increased NETs in MIS-C, in association with disease severity.

The dramatic increase of the global pandemic of SARS-CoV-2 infection represents a critical issue that needs to be investigated to evaluate the associated risk factors for acquisition and worse outcome. The interplay between immune activation and immune depression during SARS-CoV-2 infection is an intriguing topic that still needs to be clarified. The role of HIV in SARS-CoV-2 infection is not well defined.

Article Synopsis
  • At least 10% of critical COVID-19 pneumonia cases are linked to genetic defects in type I interferon immunity and autoantibodies against these cytokines, with rare X-linked variants found in 16 male individuals aged 7 to 71 years.
  • In a study involving 1,202 males with unexplained critical COVID-19, none of the asymptomatically infected participants had these deleterious variants, indicating a significant genetic component to severe illness.
  • The research highlights that X-linked recessive TLR7 deficiency plays a crucial role in about 1.8% of critical COVID-19 cases in males under 60, as effective TLR7 and plasmacytoid dendritic cells are vital for

Circulating autoantibodies (auto-Abs) neutralizing high concentrations (10 ng/mL, in plasma diluted 1 to 10) of IFN-α and/or -ω are found in about 10% of patients with critical COVID-19 pneumonia, but not in subjects with asymptomatic infections. We detect auto-Abs neutralizing 100-fold lower, more physiological, concentrations of IFN-α and/or -ω (100 pg/mL, in 1/10 dilutions of plasma) in 13.6% of 3,595 patients with critical COVID-19, including 21% of 374 patients > 80 years, and 6.

Background & Aims: The coronavirus disease 2019 (COVID-19) pandemic has posed unprecedented challenges to healthcare systems and it may have heavily impacted patients with liver cancer (LC). Herein, we evaluated whether the schedule of LC screening or procedures has been interrupted or delayed because of the COVID-19 pandemic.

Methods: An international survey evaluated the impact of the COVID-19 pandemic on clinical practice and clinical trials from March 2020 to June 2020, as the first phase of a multicentre, international, and observational project.

Objective: We aimed to investigate the effect of switching from tenofovir disoproxil fumarate (TDF) to tenofovir alafenamide (TAF) on the hepatic safety and metabolic profile.

Methods: Consecutive HIV patients, enrolled in the Surveillance Cohort Long-term Toxicity Antiretrovirals/Antivirals (SCOLTA) project, switching from TDF to TAF were included. Changes from baseline (T0) to 6-month follow-up (T1) were evaluated using paired -test and signed rank test.

Article Synopsis
  • - The study analyzed 987 patients with severe COVID-19 pneumonia and found that 101 patients had neutralizing autoantibodies (auto-Abs) against interferon-ω and various types of interferon-α at the onset of the disease.
  • - These auto-Abs interfere with the ability of type I interferons to combat SARS-CoV-2 infection in laboratory tests, but they were absent in people with mild infections and very rare in healthy individuals.
  • - The presence of these auto-Abs is linked to life-threatening COVID-19 pneumonia and appears to affect 2.6% of women and 12.5% of men, indicating a significant gender difference in this autoimmune response.

St. Giles Laboratory of Human Genetics of Infectious Diseases, Rockefeller Branch, The Rockefeller University, New York, NY, USA.

Article Synopsis
  • The study examines the varying outcomes of COVID-19 infection, from asymptomatic cases to severe pneumonia.
  • Researchers identified rare loss-of-function variants at 13 specific human loci related to immune response that are more prevalent in patients with severe illness.
  • Experimental tests revealed that these genetic variants can make human cells more susceptible to SARS-CoV-2, indicating that certain immune deficiencies may contribute to severe COVID-19 cases.

The introduction of combination of antiretroviral therapy and advancement in care of HIV have dramatically changed the natural history of patients living with HIV. Today, HIV+ patients have a life expectancy not significantly different from HIV uninfected people. However, concerns remain about all the comorbidities associated with aging and the effects of chronic therapies in such high-risk patients.

In a nationwide Italian sample of people living with HIV (PLWH), the prevalence of smoking, nicotine dependence, propensity to stop smoking, and cardiovascular profile were investigated. The nicotine dependence by Fagerström test and the propensity to stop according to the stages of change were evaluated. Associations between smoking habits and patients' characteristics were analyzed using an unconditional logistic regression model.
