Article Synopsis
  • - The study analyzed 3306 patients in Italy with relapsed/refractory chronic lymphocytic leukemia (CLL) treated with ibrutinib, showing a median follow-up of 42.2 months and a median age of 72.1 years, with 42.6% having undergone at least two prior treatments.
  • - 24-month survival probabilities indicated that 57.9% of patients remained on treatment and alive, while the median time to treatment discontinuation was 31.3 months; factors like age, performance status, and genetic mutations impacted treatment outcomes.
  • - The findings suggest that ibrutinib is generally effective for R/R CLL, but certain patient characteristics, particularly genetic factors, correspond

Background Information on the real-world use of proprotein convertase subtilisin kexin 9 inhibitors (PCKS9is) in familial hypercholesterolemia are limited. We evaluated the pattern of prescription and the long-term efficacy of alirocumab and evolocumab in Italian patients with familial hypercholesterolemia in clinical practice. Methods and Results The data set for analysis was extracted from the PCKS9i Italian Medicines Agency (AIFA) registry and included 2484 patients with heterozygous familial hypercholesterolemia (HeFH) and 62 patients with homozygous familial hypercholesterolemia (HoFH) who were prescribed PCKS9is from February 2017 to December 2021.

Article Synopsis
  • Italy has the highest rates of hepatitis C virus (HCV) infection and liver cancer deaths in Europe, but new treatments have expanded access, with over 244,000 people treated.
  • While HCV-related deaths are expected to drop by 75% by 2030, Italy is at risk of not eliminating HCV completely by that time.
  • To improve HCV elimination efforts, recommendations include expanding screening to more populations, raising awareness, ensuring continued access to direct-acting antivirals, and customizing care for high-risk groups.

Trabectedin is a marine-derived anticancer drug approved for the treatment of patients with advanced soft-tissue sarcomas (STS). Here, we aimed to analyze its use in a large cohort of STS patients treated in Italy in a real-world setting. Data on STS patients treated with trabectedin in Italy were prospectively collected from January 2013 to December 2019 by the national drug regulator, the Italian Medicines Agency (AIFA).

Real-world data on daily practice management, treatment modifications and outcome of a large cohort of chronic myeloid leukaemia (CML) patients treated with ponatinib was performed through monitoring Registries of the Italian Medicines Agency (AIFA). Overall, 666 CML subjects were included in the ponatinib registry from February 2015 to December 2020 and were eligible for analysis: 515 in chronic phase (CP), 50 in accelerated phase (AP) and 101 in blast crisis (BC). Median age at baseline was 58.

Remdesivir is the first drug approved for treatment of COVID-19 but current evidence for recommending its use for the treatment of moderate-to-severe disease is still controversial among clinical guidelines. We performed a nationwide, registry-based study including all Italian hospitalized patients with COVID-19 treated with remdesivir to assess the impact of major confounders on crude 15-day and 29-day mortality. Mortality was calculated using the Kaplan-Meier estimator and the Cox proportional-hazards model was applied to analyze the risks by patient's baseline features.

Many factors influence biomolecule binding, and its assessment constitutes an elusive challenge in computational structural biology. In this aspect, the evaluation of shape complementarity at molecular interfaces is one of the main factors to be considered. We focus on the particular case of antibody-antigen complexes to quantify the complementarities occurring at molecular interfaces.

Immunoglobulin light chain (AL) amyloidosis is caused by a small, minimally proliferating B-cell/plasma-cell clone secreting a patient-unique, aggregation-prone, toxic light chain (LC). The pathogenicity of LCs is encrypted in their sequence, yet molecular determinants of amyloidogenesis are poorly understood. Higher rates of N-glycosylation among clonal κ LCs from patients with AL amyloidosis compared to other monoclonal gammopathies indicate that this post-translational modification is associated with a higher risk of developing AL amyloidosis.

The introduction of tyrosine kinase inhibitors (TKIs) has improved the overall survival of chronic myeloid leukemia patients in chronic phase (CP-CML) and reduced the rate of disease-related mortality. Conflicting results have been however reported between data emerged from sponsored clinical trials and from population-based registries. Moreover, no data are so far available for patients treated with frontline second-generation TKIs, excluding those from sponsored studies.

Motivation: Monoclonal antibodies are essential tools in the contemporary therapeutic armory. Understanding how these recognize their antigen is a fundamental step in their rational design and engineering. The rising amount of publicly available data is catalyzing the development of computational approaches able to offer valuable, faster and cheaper alternatives to classical experimental methodologies used for the study of antibody-antigen complexes.

The frequency of patients who switch to a second-line therapy from a frontline second-generation (2gen) tyrosine kinase inhibitor (TKI) such as dasatinib and nilotinib, is still substantially unknown. We retrospectively investigated a large series of chronic phase chronic myeloid leukemia (CP-CML) patients initially treated with 2gen TKIs monitored through the Italian Medicines Agency (AIFA Agenzia Italiana del farmaco) registries. Overall, 2420 patients were analyzed over a period of 6 years.

The molecular mechanisms regulating the complex sensory system that underlies olfaction are still not completely understood. The compounds formed from the interaction of Olfactory Receptors (ORs) with volatile molecules play a crucial role in producing the sense of olfaction. Therefore, it is necessary to investigate the binding mechanisms between these receptors and small ligands.

Motivation: Understanding the molecular mechanisms of thermal stability is a challenge in protein biology. Indeed, knowing the temperature at which proteins are stable has important theoretical implications, which are intimately linked with properties of the native fold, and a wide range of potential applications from drug design to the optimization of enzyme activity.

Results: Here, we present a novel graph-theoretical framework to assess thermal stability based on the structure without any a priori information.
