Cardio-cerebral vascular diseases due to atherosclerosis are still the leading cause of death worldwide. Low-density lipoprotein cholesterol (LDL-C) and apolipoprotein B have been identified as the primary factors responsible for the atherosclerotic process, with a causal effect. Many drugs aimed at reducing LDL-C levels are already on the market, acting in different ways in terms of mechanism of action, efficacy, and safety.

Background And Purpose: Clostridioides difficile infection (CDI) is a leading cause of healthcare-associated infections worldwide, with hypervirulent strains linked to severe disease and higher mortality. This study aims to analyze the epidemiology of CDI at a tertiary-care hospital in Italy and compare clinical outcomes between patients infected with hypervirulent and non-hypervirulent strains.

Methods: A retrospective comparative study was conducted on patients diagnosed with CDI at ASST Spedali Civili di Brescia, Italy, from January 2015 to June 2023.

Osteoporosis and vertebral fractures (VFs) are frequently observed in males living with HIV (MLWH). While bisphosphonates seem effective on bone mineral density (BMD) in MLWH, data on VFs are lacking. In this real-life longitudinal study performed on 118 MLWH (median age 53) who were followed-up for a median of 7 years, we aimed to evaluate the long-term efficacy of oral bisphosphonates on VFs in MLWH.

Pyelo-hepatic abscess is a rare complication of upper urinary tract infections (UTIs). We describe a case of polymicrobial pyelo-hepatic abscess in an immunocompetent patient. A 71-year-old male patient with a double-J stent for right ureteral lithiasis was admitted in our Infectious Diseases Department for a pyelo-hepatic abscess.

Article Synopsis
  • The study focuses on twin pregnancies in donkeys, which can lead to abortions and high neonatal mortality, emphasizing the importance of detecting and managing these pregnancies effectively.
  • Out of 25 detected twin pregnancies, a significant majority (87.5%) of unilateral cases experienced natural reduction by 20-21 days after ovulation, while bilateral cases did not.
  • The overall pregnancy rate after 28 days was 92%, and the live foal rate was 87%, indicating that allowing natural reduction or manually crushing one embryo can lead to successful outcomes for single pregnancies.

Background: Lenacapavir is a long-acting HIV-1 capsid inhibitor for treatment of HIV-1 infection. We evaluated the efficacy and safety of lenacapavir in combination with an investigator-selected optimized background regimen (OBR) after 104 weeks in adults with multidrug-resistant HIV-1.

Methods: This ongoing, international, Phase 2/3 trial at 42 sites included 72 adults living with multidrug-resistant HIV-1.

  • Female sexual dysfunction is common among women worldwide, especially those living with chronic conditions like HIV, yet there is limited research on this topic.
  • The review aims to summarize the current understanding of sexual dysfunction specifically in women living with HIV, considering various influencing factors such as biological, psychological, and sociocultural aspects.
  • A comprehensive clinical approach that addresses the complexities of sexual dysfunction could enhance the sexual health and overall quality of life for women living with HIV.

Cefiderocol is a new molecule effective against multidrug-resistant (MDR) Gram-negative pathogens. Currently, there is limited evidence regarding the use of cefiderocol in central nervous system (CNS) infections. Data on the cerebrospinal fluid penetration rate of cefiderocol are limited and heterogeneous, and there is no consensus on the dosing scheme of cefiderocol to penetrate the blood-brain barrier.

Dolutegravir (DTG) is one of the most prescribed antiretroviral drugs for treating people with HIV infection, including women of child-bearing potential or pregnant. Nonetheless, neuropsychiatric symptoms are frequently reported. Early reports suggested that, probably in relation to folic acid (FA) shortage, DTG may induce neural tube defects in infants born to women taking the drug during pregnancy.

Article Synopsis
  • A study at a Northern Italian hospital investigated the incidence of post-COVID-19 conditions (PCCs) among 3,817 people living with HIV (PLWH) during the pandemic.
  • Out of 653 diagnosed with COVID-19, 34.9% reported persistent symptoms three months later, with fatigue and muscle pain being the most common.
  • The research found that females had a higher risk for PCCs, while hospitalization during the acute phase increased the likelihood of developing these conditions, regardless of other health factors or vaccination status.

  • Researchers studied how different immune endotypes affect responses to anakinra treatment in patients with severe pneumonia caused by COVID-19 during the SAVE-MORE trial.
  • The study found that many patients transitioned between immune endotypes during treatment, with anakinra helping those with the adaptive endotype to maintain better outcomes.
  • Anakinra also reduced the risk of severe respiratory failure in patients with a coagulopathic endotype compared to placebo, indicating its potential benefits in managing sepsis-related conditions.

We evaluated the impact of COVID-19 vaccination on disease outcome in hospitalized patients with SARS-CoV-2 infection with a prospective study. 745 vaccinated and 451 unvaccinated patients consecutively admitted to a COVID-19 Hospital from 1st September 2021 to 1st September 2022 were included. Compared with unvaccinated cases, vaccinated patients were older, had more comorbidities, but had a lower risk of O2 need (odds ratio, OR, 0.

  • Prisons have a higher prevalence of communicable diseases like hepatitis C virus (HCV), necessitating routine testing and direct treatment access for inmates.
  • In a study of 5,378 admissions in two prisons in Brescia, 54.5% underwent HCV screening, revealing a 9.2% positivity rate with a significant number showing detectable virus levels.
  • Despite 77 treatments being administered, follow-up care for released prisoners was low, indicating a need for better education and improved test-and-treat programs to reduce HCV by 2030 through collaborative efforts with local healthcare services.

  • Before 2022, monkeypox (Mpox) was rarely reported outside Africa, but during a 2022 outbreak, cases were mostly among men who have sex with men (MSM) in Italy.
  • A survey of 144 MSM patients revealed that most had heard of Mpox, but many lacked comprehensive knowledge about its transmission and risk.
  • Despite fears of infection, over half did not take additional precautions, and about one-third were hesitant to accept the vaccine, highlighting a significant need for better awareness and education on Mpox.

  • Elderly patients with severe COVID-19 showed reduced T-cell diversity and weaker immune responses compared to younger patients, highlighting age-related vulnerabilities in fighting the virus.
  • The study used advanced sequencing techniques to analyze T-cell responses in both COVID-19 patients and individuals with inborn errors of immunity who received an mRNA vaccine, revealing specific genetic associations affecting these responses.
  • Findings indicated that mRNA vaccines successfully enhanced the T-cell responses in individuals with immune deficiencies, suggesting their effectiveness even in populations that struggle to develop strong immune responses on their own.

  • The study aimed to evaluate the relationship between the plasma levels of efavirenz (EFV) and its metabolite 8-hydroxy-EFV (8-OH-EFV) with neurocognitive impairment and central nervous system (CNS) side effects in patients switching from EFV to rilpivirine.
  • Analysis of 104 patients showed that although higher levels of 8-OH-EFV were significantly linked to more CNS side effects, EFV levels only showed a marginal association with cognitive performance, particularly in executive and language functions.
  • The findings suggest that 8-OH-EFV may have a more pronounced impact on CNS side effects, while EFV's influence on cognitive function is less clear, indicating differing

Background: Auto-antibodies neutralizing the activity of type I interferons have been recently described in patients infected by SARS-CoV-2. They can be present even before the onset of the infection. Since type I interferons exert a dichotomous role in the pathogenesis of acute versus chronic HIV infection and auto-antibodies are often found in untreated and anti-retroviral treated HIV patients, we investigated whether auto-antibodies anti-type I interferons are present at high prevalence in those HIV patients with concomitant opportunistic infections (OIs).
