HCV infections are common among people who use drugs (PWUDs), when sharing needles, syringes, or other equipment for injected drugs. The advent of pangenotypic direct-antiviral agents (DAA) in 2017 transformed the treatment landscape for HCV, but PWUDs remain a complex and hard-to-treat population with high risk of HCV reinfection. The aim of this real-world analysis was to characterize the demographic and clinical features of PWUDs in Italy, also focusing on comorbidity profile, treatment with DAAs, resource consumptions for the National Health System (NHS).Patients and Methods: During 01/2011– 06/2020, administrative databases of Italian healthcare entities, covering 3,900,000 individuals, were browsed to identify PWUDs with or without HCV infection. Among HCV+ patients, a further stratification was made into treated and untreated with DAAs. The date of PWUD or HCV first diagnosis or DAA first prescription was considered as index-date. Patients were then followed-up for one year. Alcohol-dependency was also investigated.Results: Total 3690 PWUDs were included, of whom 1141 (30.9%) PWUD-HCV+ and 2549 (69.1%) PWUD-HCV-. HCV-positive were significantly older (43.6 vs 38.5 years, p < 0.001), had a worse comorbidity profile (Charlson-index: 0.8 vs 0.4, p < 0.001), and high rates of psychiatric, respiratory, dermatological, musculoskeletal diseases and genitourinary (sexually transmitted) infections. Moreover, they received more drug prescriptions (other than DAAs, like anti-acids, antiepileptics, psycholeptics) and had undergone more frequent hospitalization, predominantly for hepatobiliary, respiratory system and mental disorders. DDA-untreated had significantly higher Charlson-index than DAA-treated (0.9 vs 0.6, p = 0.003). Alcoholism was found in 436 (11.8%) cases.Conclusion: This Italian real-world analysis suggests that PWUDs with HCV infection, especially those untreated with DAAs, show an elevated drug consumption due to their complex clinical profile. These findings could help to ameliorate the healthcare interventions on PWUDs with HCV infection.Keywords: drug abuse, hepatitis C virus, alcohol dependency, real-world evidence

PSO patients (identified by PSO hospitalization, and/or active exemption code and/or a topical anti-psoriatic medication prescription) were included. In prevalent patients identified during 2017– 2018-2019-2020, baseline characteristics and treatment patterns were investigated. Moreover, b/tsDMARD drug utilization (focusing on persistence, monthly dosage, and mean duration between prescriptions) was evaluated in bionaïve patients included during 2015 and 2018.Results: PSO was diagnosed in 241,552 (in 2017), 269,856 (in 2018), 293,905 (in 2019) and 301,639 (in 2020) patients. At the index date, almost 50% of patients had not received systemic medications, and 2% had received biological treatment. Among the b/tsDMARD-treated patients, a decrease in the use of tumour necrosis factor (TNF) inhibitors (60.0– 36.4%, from 2017 to 2020) and an increase in the use of interleukin (IL) inhibitors (36.3– 50.6%, from 2017 to 2020) were observed. In 2018, the persistence rates of TNF inhibitors and IL inhibitors in bionaïve patients ranged from 60.8– 79.7% and 83.3– 87.9%, respectively.Conclusion: This real-world study of PSO drug utilization in Italy showed that a significant number of patients were not treated with systemic medications and only 2% of patients were treated with biologics. An increase in the use of IL inhibitors and a decrease in the prescription of TNF inhibitors over years were found. Patients treated with biologics were highly persistent with treatment. These data provide insight into routine clinical practice for PSO patients in Italy, suggesting that the optimization of treatment for PSO still represents an unmet medical need.Keywords: psoriasis systemic medications, psoriasis biological drugs, TNF inhibitors, IL inhibitors, treatment optimization, real world evidence

All adult patients with at least one hospitalization for focal epilepsy and an electroencephalogram (between 01/2010 and 12/2019), and at least one prescription of antiseizure medication (ASM) (between 01/2011 and 12/2018) were included in the study. Patients with at least two treatment failures and treated with a subsequent ASM were considered DRE.Results: Overall, 1897 patients with focal epilepsy (mean age 56 years, 47% male) were identified, of which 485 (25.6%) with DRE (mean age 53 years, 43% male). Among patients with focal epilepsy and DRE, respectively, 48% and 54% had essential hypertension, 23.4% and 26.6% had cardiovascular disease, and 46.3% and 62.1% had peptic ulcer/prescription of gastric secretion inhibitors. During follow-up, patients with focal epilepsy maintained first-line treatment for 53.9 months; among these, 52% passed to the second-line, and 485 (25.6% of the total) began third-line treatment. In patients with focal epilepsy, the mean cost was € 4448 (of which € 1410 were epilepsy-related), and in DRE patients total expenditures averages € 5825 (of which € 2165 were epilepsy-related). In both patients with focal epilepsy and DRE, hospitalizations represented the most impacting item of expenditure.Conclusion: The present analysis conducted in a setting of Italian clinical practice has shown that 25% of patients with focal epilepsy were resistant to antiepileptic treatments. Furthermore, these results showed that health-care costs for the management of epileptic patients were mainly accountable for the costs related to the disease-management and to hospitalizations.Keywords: epilepsy, real-world evidence, clinical practice, pharmacoutilization, healthcare resource consumption

The mechanism of action of low-dose aspirin in the prevention of colorectal cancer (CRC) remains largely hypothetical. We aimed to compare the effects of low-dose aspirin (100 mg/day for 7 days) given to 40 individuals undergoing CRC screening on the extent of cyclooxygenase (COX)-1 acetylation at serine-529 (AceCOX-1), in blood platelets vs. colorectal mucosa, at 7 (group 1) and 24 h (group 2) after dosing. A significantly ( P < 0.01) lower %AceCOX-1 was detected in colonic and rectal mucosa (average 64%) vs. platelets (average 75%) in both groups. This effect was associated with an average 46% ( P < 0.01) and 35% ( P < 0.05) reduction in prostaglandin (PG) E2 levels and phosphorylated S6 (p-S6) levels, respectively. Rectal mucosal levels of p-S6/S6 significantly ( P < 0.01) correlated with PGE2. These findings demonstrate that low-dose aspirin produces long-lasting acetylation of COX-1 and downregulation of p-S6 in human colorectal mucosa, an effect that may interfere with early colorectal carcinogenesis.

Objective: To examine the clinical burden and healthcare resource utilization (HCRU) among patients with transfusion-dependent β-thalassemia (TDT) and patients with sickle cell disease (SCD) with recurrent vaso-occlusive crises (VOCs) in Italy., Methods: Eligible patients were identified from an administrative claims database from 1 January 2010 and 1 February 2019. Patients with TDT had ≥ 1 iron chelation treatment, ≥ 8 red blood cell transfusions (RBCTs) during any 12-month period, and ≥ 12 months of available data pre- and post-index (i.e., first RBCT claim). Patients with SCD with recurrent VOCs had ≥ 2 VOCs/year in ≥ 2 consecutive years and ≥ 12 months of available data pre- and post-index (second VOC claim in the second of 2 consecutive years). Patients were propensity score matched to five controls by age, sex, geographic area, and index year. Clinical and HCRU outcomes were evaluated post-index., Results: In total, 214 patients with TDT and 111 patients with SCD with recurrent VOCs were matched to 1070 and 555 controls, respectively. Both patient groups had substantially higher mortality rates than controls (TDT: 4.8 versus 0.8 deaths per 100 person-years; SCD: 1.6 versus 0.4 deaths per 100 person-years). Clinical complications were prevalent in both patient groups. Compared with controls, both patient groups had significantly higher mean rates of all-cause hospitalizations (TDT: 1.4 versus 0.1; SCD: 2.0 versus 0.1) and outpatient services (TDT: 21.9 versus 1.6; SCD: 6.2 versus 1.0) per patient per year (all: p < 0.05)., Conclusions: Management of TDT and SCD in Italy is associated with significant clinical and health system burden, highlighting the need for new treatments that eliminate RBCTs and VOCs., (© 2024.

Micro- and nano-plastics (MNPLs) can move along the food chain to higher-level organisms including humans. Three significant routes for MNPLs have been reported: ingestion, inhalation, and dermal contact. Accumulating evidence supports the intestinal toxicity of ingested MNPLs and their role as drivers for increased incidence of colorectal cancer (CRC) in high-risk populations such as inflammatory bowel disease (IBD) patients. However, the mechanisms are largely unknown. In this review, by using the leading scientific publication databases (Web of Science, Google Scholar, Scopus, PubMed, and ScienceDirect), we explored the possible effects and related mechanisms of MNPL exposure on the gut epithelium in healthy conditions and IBD patients. The summarized evidence supports the idea that oral MNPL exposure may contribute to intestinal epithelial damage, thus promoting and sustaining the chronic development of intestinal inflammation, mainly in high-risk populations such as IBD patients. Colonic mucus layer disruption may further facilitate MNPL passage into the bloodstream, thus contributing to the toxic effects of MNPLs on different organ systems and platelet activation, which may, in turn, contribute to the chronic development of inflammation and CRC development. Further exploration of this threat to human health is warranted to reduce potential adverse effects and CRC risk.

Aims: To compare medication adherence, lipid goal attainment, and healthcare costs between patients receiving a single-pill combination (SPC) vs. a free combination treatment (FCT) of rosuvastatin/ezetimibe (ROS/EZE) in Italy., Methods and Results: Administrative databases of healthcare entities covering ∼7 million individuals were used to identify adults prescribed with ROS/EZE as SPC or FCT between January 2018 and June 2020. Adherence was calculated as the proportion of days covered (PDC) after cohort balancing by propensity score matching. Patients with available LDL cholesterol testing were assessed for the proportion of those who at baseline were above lipid targets recommended by ESC/EAS Guidelines for their cardiovascular risk category and reached the target during follow-up. Among 25 886 patients on SPC and 7309 on FCT, adherent patients were more represented in SPC than FCT cohort (56.8 vs. 44.5%, P < 0.001), and this difference remained significant ( P < 0.001) after stratification by cardiovascular risk (very high, high, and other). The proportion of patients reaching LDL cholesterol target at 1 year follow-up was significantly ( P < 0.001) higher in SPC vs. FCT cohort: 35.4 vs. 23.8% for very high cardiovascular risk, 46.9 vs. 23.1% for high risk and 71.6 vs. 49.5% for other risk. Total healthcare costs per patient at 1 year follow-up were lower in SPC vs. FCT users (2337€ vs. 1890€, P < 0.001). In both cohorts, costs were mainly driven by drug expenses and hospitalizations., Conclusion: This real-world analysis in dyslipidaemic patients found that treatment with ROS/EZE as SPC resulted in better adherence, higher chances of reaching lipid goals, and cost savings over FCT, in all cardiovascular risk categories., Competing Interests: Conflict of interest: A.Z. reports speaker fees and consultant fees from Amgen, Amarin, Amryt, AlfaSigma, Abbott, Viatris, Novartis, Sanofi, Sobi, Servier, and Daiichi Sankyo.

Introduction: Adherence to cardiovascular drug treatment can significantly benefit from a reduced pill burden, but data on this matter derived from real-life settings are currently scanty. This analysis assessed the possible changes in adherence in patients treated with rosuvastatin and ezetimibe (ROS/EZE) as free multi-pill combination who switched to ROS/EZE as single-pill combination in the setting of real clinical practice in Italy., Methods: A retrospective analysis was conducted on the administrative databases for a catchment area of about seven million health-assisted residents. Adults receiving ROS/EZE as a single-pill combination from January 2010 to June 2020 (followed up to 2021) were identified. The date of the first prescription of single-pill combination of ROS/EZE was considered as the index date. The analysis included the users of ROS/EZE as a free combination during the year before the index date. Baseline demographic and clinical characteristics were collected during the period of data availability prior to the index date. Adherence to therapy was evaluated as proportion of days covered (PDC), namely the percentage of days during which a patient had access to medication, in the 12-month interval preceding or following the index date (PDC < 25% non-adherence; PDC = 25-75% partial adherence; PDC > 75% adherence)., Results: A total of 1219 patients (61.1% male, aged 66.2 ± 10.4 years) were included. Cardiovascular comorbidities were found in 83.3% of them, diabetes in 26.4%, and a combination of both in 16.2%. Single-pill combination of ROS/EZE was associated with a higher proportion of adherent patients compared to free-pill combination (75.2% vs 51.8%, p < 0.001)., Conclusions: This real-world analysis suggested that switching from a regimen based on separate pills to one based on a single-pill combination resulted in improved adherence to ROS/EZE therapy., (© 2024.

Background: Invasive fungal infections (IFI), prevalent in critically ill ICU patients, have gained attention due to post-COVID-19 epidemiological shifts. Notably, COVID-19-associated aspergillosis and candidiasis pose significant risks. WHO recognises key fungal pathogens, emphasising the need for enhanced research and interventions., Methods: The CHARTER-IFI study retrospectively examines 186,310 individuals admitted to ICUs in Italy from 01/01/2012-01/09/2023, utilising administrative databases covering around 10 million inhabitants. Adult patients were included having at least one ICU discharge diagnosis of IFI at their first IFI-related hospitalisation and having at least 12 months of available data prior to this hospitalisation., Results: A total of 746 IFI patients discharged from ICU (incidence of 4.0 per 1000 ICU-hospitalised patients), were included. Median age was 68 years, 63% were males, and the overall Charlson Comorbidity Index was 2.2. The top three diagnoses were candidiasis (N = 501, 2.7/1000 ICU-hospitalised patients), aspergillosis (N = 71, 0.4/1000), and pneumocystosis (N = 55, 0.3/1000). The evaluation of the comorbidity profile in IFI patients revealed the presence of hypertension (60.5%), use of systemic GC/antibacterials (45.3% during 12 months before and 18.6% during 3 months before hospital admission), cancer (23.1%), diabetes (24.3%) and cardiovascular diseases (23.9%). The mean (±SD) length of hospitalisation in ICU was 19.9 ± 24.1 days (median 11 days), and deaths occurred in 36.1% of IFI patients (within 30 days from discharge)., Conclusions: This retrospective analysis among ICU-hospitalised patients described the burden of IFI in ICU, and its understanding could be crucial to strengthen surveillance, investments in research, and public health interventions as required by WHO., (© 2024 The Author(s).

Introduction: Real-world data are used to inform decision-makers and optimise therapeutic management for patients with ulcerative colitis (UC) and Crohn's disease (CD). We analysed data on the epidemiology (by using proxies of prevalence and incidence), patient characteristics, treatment patterns and associated healthcare direct costs for the management of patients with UC and patients with CD in Italy., Methods: This retrospective observational study used administrative databases from eight Local Health Units geographically distributed across Italy. Adult patients with a hospitalisation and/or an exemption for UC or CD were included. Study outcomes were summarised descriptively, and limited statistical tests were performed., Results: At baseline, 9255 adults with UC and 4747 adults with CD were included. Mean (standard deviation) age at inclusion was 54.0 (18.4)/48.6 (18.1) years, for UC/CD. The estimated average incidence of UC and CD for the period 2013-2020 was 36.5 and 18.7 per 100,000, respectively. The most frequently prescribed drug category for patients with UC/CD was conventional treatment [mesalazine and topical corticosteroids (67.4%/61.1%), immunomodulators and systemic corticosteroids (43.2%/47.7%)], followed by biologic treatments (2.1%/5.1%). The mean annual total direct cost per patient was 7678 euro (€), for UC and €6925 for CD., Conclusion: This analysis, carried-out in an Italian clinical setting, may help to optimise therapy for patients with UC and CD and provide relevant clinical practice data to inform decision-makers., (© 2024.

Background: Nanoplastics, an emerging form of pollution, are easily consumed by organisms and pose a significant threat to biological functions due to their size, expansive surface area, and potent ability to penetrate biological systems. Recent findings indicate an increasing presence of airborne nanoplastics in atmospheric samples, such as polystyrene (PS), raising concerns about potential risks to the human respiratory system., Methods: This study investigates the impact of 800 nm diameter-PS nanoparticles (PS-NPs) on A549, a human lung adenocarcinoma cell line, examining cell viability, redox balance, senescence, apoptosis, and internalization. We also analyzed the expression of hallmark genes of these processes., Results: We demonstrated that PS-NPs of 800 nm in diameter significantly affected cell viability, inducing oxidative stress, cellular senescence, and apoptosis. PS-NPs also penetrated the cytoplasm of A549 cells. These nanoparticles triggered the transcription of genes comprised in the antioxidant network [SOD1 (protein name: superoxide dismutase 1, soluble), SOD2 (protein name: superoxide dismutase 2, mitochondrial), CAT (protein name: catalase), Gpx1 (protein name: glutathione peroxidase 1), and HMOX1 (protein name: heme oxygenase 1)], senescence-associated secretory phenotype [Cdkn1a (protein name: cyclin-dependent kinase inhibitor 1A), IL1A (protein name: interleukin 1 alpha), IL1B (protein name: interleukin 1 beta), IL6 (protein name: interleukin 6), and CXCL8 (protein name: C-X-C motif chemokine ligand 8)], and others involved in the apoptosis modulation [BAX (protein name: Bcl2 associated X, apoptosis regulator), CASP3 (protein name: caspase 3), and BCL2 (protein name: Bcl2, apoptosis regulator)]., Conclusion: Collectively, this investigation underscores the importance of concentration (dose-dependent effect) and exposure duration as pivotal factors in assessing the toxic effects of PS-NPs on alveolar epithelial cells. Greater attention needs to be directed toward comprehending the risks of cancer development associated with air pollution and the ensuing environmental toxicological impacts on humans and other terrestrial mammals., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Milillo, Aruffo, Di Carlo, Patruno, Gatta, Bruno, Dovizio, Marinelli, Dimmito, Di Giacomo, Paolini, Pesce and Ballerini.)

Background: This real-world analysis aimed at characterizing patients hospitalized for alopecia areata (AA) in Italy, focusing on comorbidities, treatment patterns and the economic burden for disease management., Methods: Administrative databases of healthcare entities covering 8.9 million residents were retrospectively browsed to include patients of all ages with hospitalization discharge diagnosis for AA from 2010 to 2020. The population was characterized during the year before the first AA-related hospitalization (index-date) and followed-up for all the available successive period. AA drug prescriptions and treatment discontinuation were analyzed during follow-up. Healthcare costs were also examined., Results: Among 252 patients with AA (mean age 32.1 years, 40.9% males), the most common comorbidities were thyroid disease (22.2%) and hypertension (21.8%), consistent with literature; only 44.4% (112/252) received therapy for AA, more frequently with prednisone, triamcinolone and clobetasol. Treatment discontinuation (no prescriptions during the last trimester) was observed in 86% and 88% of patients, respectively at 12 and 24-month after therapy initiation. Overall healthcare costs were 1715€ per patient (rising to 2143€ in the presence of comorbidities), mostly driven by hospitalization and drugs expenses., Conclusions: This first real-world description of hospitalized AA patients in Italy confirmed the youth and female predominance of this population, in line with international data. The large use of corticosteroids over other systemic therapies followed the Italian guidelines, but the high discontinuation rates suggest an unmet need for further treatment options. Lastly, the analysis of healthcare expenses indicated that hospitalizations and drugs were the most impactive cost items.

Background: Respiratory syncytial virus (RSV) is among the leading causes of hospitalization due to lower respiratory tract infections (LRTIs) in children younger than 5 years worldwide and the second cause of infant death after malaria. RSV infection occurs in almost all the infants before the second year of life with variable clinical severity, often requiring medical assistance. This analysis investigated patients aged 0-5 years with RSV infection focusing on epidemiology, clinical features, and economic burden of RSV-associated hospitalizations in a setting of Italian real clinical practice., Methods: An observational retrospective analysis was conducted on administrative databases of healthcare entities covering around 2.6 million residents of whom 120,000 health-assisted infants aged < 5 years. From 2010 to 2018, pediatric patients were included in the presence of hospitalization discharge diagnosis for RSV infections, and RSV-related acute bronchiolitis or pneumonia. Epidemiology, demographics, clinical picture and costs were evaluated in RSV-infected patients, overall and stratified by age ranges (0-1, 1-2, 2-5 years) and compared with an age-matched general population., Results: Overall 1378 RSV-infected children aged 0-5 years were included. Among them, the annual incidence rate of RSV-related hospitalizations was 175-195/100,000 people, with a peak in neonates aged < 1 year (689-806/100,000). While nearly 85% of infected infants were healthy, the remaining 15% presented previous hospitalization for known RSV risk factors, like preterm birth, or congenital heart, lung, and immune diseases. The economic analysis revealed that direct healthcare costs per patient/year were markedly higher in RSV patients than in the general population (3605€ vs 344€)., Conclusions: These findings derived from the real clinical practice in Italy confirmed that RSV has an important epidemiological, clinical, and economic burden among children aged 0-5 years. While the complex management of at-risk infants was confirmed, our data also highlighted the significant impact of RSV infection in infants born at term or otherwise healthy, demonstrating that all infants need protection against RSV disease, reducing then the risk of medium and long-term complications, such as wheezing and asthma., (© 2024.

Introduction: In a large nationwide administrative database including ∼35 % of Italian population, we analyzed the impact of oral anticoagulant treatment (OAT) in patients with a hospital diagnosis of non-valvular atrial fibrillation (NVAF)., Methods and Results: Of 170404 OAT-naïve patients (mean age 78.7 years; 49.4 % women), only 61.1 % were prescribed direct oral anticoagulants, DOACs, or vitamin-K antagonists, VKAs; 14.2 % were given aspirin (ASA), and 24.8 % no anti-thrombotic drugs (No Tx). We compared ischemic stroke (IS), IS and systemic embolism (IS/SE), intracranial hemorrhage (ICH), major bleeding (MB), major gastro-intestinal bleeding, all-cause deaths and the composite outcome, across four propensity-score matched treatment cohorts with >15400 patients each. Over 2.9±1.5 years, the incidence of IS and IS/SE was slightly less with VKAs than with DOACs (1.62 and 1.84 vs 1.81 and 1.99 events.100 person-years; HR=0.85, 95%CI=0.76-0.95 and HR=0.87, 95%CI=0.78-0.97). This difference disappeared in a sensitivity analysis which excluded those patients treated with low-dose of apixaban, edoxaban, or rivaroxaban (41.7% of DOACs cohort). Compared with DOACs, VKAs were associated with greater incidence of ICH (1.09 vs 0.81; HR=1.38, 95%CI=1.17-1.62), MB (3.78 vs 3.31; HR=1.14, 95%CI=1.02-1.28), all-cause mortality (9.66 vs 10.10; HR=1.07, 95%CI=1.02-1.11), and composite outcome (13.72 vs 13.32; HR=1.04, 95%CI=1.01-1.08). IS, IS/SE, and mortality were more frequent with ASA or No Tx than with VKAs or DOACs (p<0.001 for all comparisons)., Conclusions: Beyond confirming the association with a better net clinical benefit of DOACs over VKAs, our findings substantiate the large proportion of NVAF patients still inappropriately anticoagulated, thereby reinforcing the need for educational programs., Competing Interests: Declaration of Competing Interest SF: speaker for BMS/Pfizer, Bruno Farmaceutici, Daiichi-Sankyo, Menarini Group; research grants from Menarini Group.

Background: The therapeutic management of immune-mediated thrombotic thrombocytopenic purpura (iTTP) has recently benefited from the introduction of caplacizumab, an agent directed at the inhibition of platelet aggregation. This real-world analysis investigated the epidemiology and the demographic and clinical characteristics of iTTP patients in Italy before and after caplacizumab introduction in 2020. Methods: Hospitalized adults with iTTP were included using the administrative databases of healthcare entities covering 17 million residents. Epidemiological estimates of iTTP considered the 3-year period before and after caplacizumab introduction. After stratification by treatment with or without caplacizumab, iTTP patients were characterized for their baseline features. Results: The annual incidence before and after 2020 was estimated in the range of 4.3-5.8 cases/million and 3.6-4.6 cases/million, respectively. From 2018 to 2022, 393 patients with iTTP were included, and 42 of them were treated with caplacizumab. Caplacizumab-treated patients showed better clinical outcomes, with tendentially shorter hospital stays and lower mortality rates (no treated patients died at either 1 month or 3 months after caplacizumab treatment initiation, compared to 10.5% and 11.1% mortality rates at 1 and 3 months, respectively, of the untreated ones). Conclusions: These findings may suggest that caplacizumab advent provided clinical and survival benefits for patients with iTTP.

Background/aims: This analysis estimated the number of inflammatory bowel disease (IBD) patients presenting criteria of eligibility for biological therapies in an Italian real-world setting., Methods: An observational analysis was performed on administrative databases of a sample of Local Health Units, covering 11.3% of the national population. Adult IBD patients (CD or UC) from 2010 to the end of data availability were included. Eligibility criteria for biologics were the following: Criterion A, steroid-refractory active disease; Criterion B, steroid-dependent patients; Criterion C, intolerance or contraindication to conventional therapies; Criterion D, severe relapsing disease; Criterion E (CD only), highly active CD disease and poor prognosis., Results: Of 26,781 IBD patient identified, 18,264 (68.2%) were treated: 3,125 (11.7%) with biologics and 15,139 (56.5%) non-biotreated. Among non-biotreated, 7,651 (28.6%) met at least one eligibility criterion for biologics, with criterion B (steroid-dependence) and criterion D (relapse) as the most represented (58-27% and 56-76%, respectively). Data reportioned to the Italian population estimated 67,635 patients as potentially eligible for biologics., Conclusions: This real-world analysis showed a trend towards undertreatment with biologics in IBD patients with 28.6% being potentially eligible, suggesting that an unmet medical need still exists among the Italian general clinical practice for IBD management., Competing Interests: Declaration of Competing Interest Flavio Caprioli served as consultant to: Abbvie, MSD, Takeda, Janssen, Roche, Celgene, Bristol-Meyers Squibb, Galapagos, Gllead, Pfizer, Mundipharma, Galapagos, Biogen, Ferring.

Introduction: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are rare autoimmune diseases triggering inflammation of small vessels. This real-world analysis was focused on the most common AAV forms, granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), to describe patients' demographic and clinical characteristics, therapeutic management, disease progression, and the related economic burden., Methods: A retrospective analysis was conducted on administrative databases of a representative sample of Italian healthcare entities, covering approximately 12 million residents. Between January 2010 and December 2020, adult GPA patients were identified by payment waiver code or hospitalization discharge diagnosis, and MPA patients by payment waiver code with or without hospitalization discharge diagnosis. Clinical outcomes were evaluated through AAV-related hospitalizations, renal failure onset, and mortality. Economic analysis included healthcare resource utilization deriving from drugs, hospitalizations, and outpatient specialist services. The related mean direct costs year/patient were also calculated in patients stratified by presence/absence of glucocorticoid therapy and type of inclusion criterion (hospitalization/payment waiver code)., Results: Overall, 859 AAV patients were divided into GPA (n = 713; 83%) and MPA (n = 146; 17%) cohorts. Outcome indicators highlighted a clinically worse phenotype associated with GPA compared to MPA. Cost analysis during follow-up showed tendentially increased expenditures in glucocorticoid-treated patients versus untreated (overall AAV: €8728 vs. €7911; GPA: €9292 vs. €9143; MPA: €5967 vs. €2390), mainly driven by drugs (AAV: €2404 vs. €874; GPA: €2510 vs. €878; MPA: €1881 vs. €854) and hospitalizations., Conclusion: Among AAV forms, GPA resulted in a worse clinical picture, higher mortality, and increased costs. This is the first real-world pharmaco-economic analysis on AAV patients stratified by glucocorticoid use on disease management expenditures. In both GPA and MPA patients, glucocorticoid treatment resulted in higher healthcare costs, mostly attributable to medications, and then hospitalizations, confirming the clinical complexity and economic burden for management of patients with autoimmune diseases under chronic immunosuppression., (© 2023.

Background: Psoriasis (PSO) patients can benefit from the growing availability of novel biological agents, that are often underused or discontinued. This real-world analysis estimated PSO patients potentially eligible and currently untreated with biologics in Italy., Methods: An observational analysis was performed on administrative databases of a pool of healthcare entities, covering 11.3% of Italian population. During the inclusion period (2010- 2020), patients were identified by: 1) at least one prescription of topical drugs for PSO; or 2) active exemption for PSO; or 3) at least one PSO hospital discharge diagnosis. The index-date was the first PSO identification across inclusion period. Eligibility for biologics was evaluated prior to index-date (characterization period) through two not-mutually exclusive criteria: Criterion A, failure of at least one systemic treatment, and/or Criterion B, onset of psoriatic arthritis (PsA). Data were re-proportioned to the Italian population., Results: The study sample showed a PSO prevalence of 2%. Projection to 2020 national population (N=59,236.213) estimated 1.43 million Italian patients affected by PSO: 95% treated with conventional therapies, 4% with biologics, and 1% untreated. Among those non-treated with biologics, 3.8% of overall PSO patients met one or both eligibility criteria for biologics, specifically 25% met criterion A (failure to conventional treatments), 68% criterion B (PsA co-diagnosis), and 7% met both. About half of them had 1 or 2 comorbidities and 30% above 3., Conclusions: These findings from real clinical practice estimated about 4% PSO patients potentially eligible for biologics, but still untreated, with nearly one-third exhibiting a complex comorbidity profile.

Background/aims: This real-world analysis evaluated the persistence and direct healthcare costs of Crohn's Disease (CD) patients treated with biologics in Italy., Methods: A retrospective analysis on administrative databases of Italian healthcare entities, covering 10.4 million residents, was performed. Adult CD patients under biologics between 2015 and 2020 were included and attributed to first/second treatment line based on absence/presence of biologic prescriptions 5-years before index-date (first biologic prescription)., Results: Of 16,374 CD patients identified, 1,398 (8.5%) were biologic-treated: 1,256 (89.8%) in first line and 135 (9.7%) in second line. Kaplan-Meier curves estimated a higher persistence for ustekinumab-treated patients followed by vedolizumab, infliximab and adalimumab, in both lines. Considering baseline variables and adalimumab as reference, infliximab in first line (HR: 0.537) and ustekinumab in first (HR: 0.057) and second line (HR: 0.213) were associated with significantly reduced risk of drug-discontinuation. First line total/average healthcare direct-costs were €13,637, €11,201, €17,104 and €18,340 in patients persistent on adalimumab, infliximab, ustekinumab and vedolizumab, respectively., Conclusions: This real-world analysis showed differences in persistence over 12-months between biologic treatments, being higher in ustekinumab-treated group, followed by vedolizumab, infliximab and adalimumab. Patients' management was associated with comparable direct healthcare costs among treatment lines, mainly driven by drug-related expenses., Competing Interests: Conflict of Interest Janssen-Cilag SpA purchased the study report that is the basis for this manuscript.

Background: This analysis investigated the role of hypertriglyceridemia on renal function decline and development of end-stage kidney disease (ESKD) in a real-world clinical setting., Methods: A retrospective analysis using administrative databases of 3 Italian Local Health Units was performed searching patients with at least one plasma triglyceride (TG) measurement between 2013 and June 2020, followed-up until June 2021. Outcome measures included reduction in estimated glomerular filtration rate (eGFR) ≥30% from baseline and ESKD onset. Subjects with normal (normal-TG), high (HTG) and very high TG levels (vHTG) (respectively <150 mg/dL, 150-500 mg/dL and >500 mg/dL) were comparatively evaluated., Results: Overall 45,000 subjects (39,935 normal-TGs, 5,029 HTG and 36 vHTG) with baseline eGFR of 96.0 ± 66.4 mL/min were considered. The incidence of eGFR reduction was 27.1 and 31.1 and 35.1 per 1000 person-years, in normal-TG, HTG and vHTG subjects, respectively (P<0.01). The incidence of ESKD was 0.7 and 0.9 per 1000 person-years, in normal-TG and HTG/vHTG subjects, respectively (P<0.01). Univariate and multivariate analyses revealed that HTG subjects had a risk of eGFR reduction or ESKD occurrence (composite endpoint) increased by 48% compared to normal-TG subjects (adjusted OR:1.485, 95%CI 1.300-1.696; P<0.001). Moreover, each 50 mg/dL increase in TG levels resulted in significantly greater risk of eGFR reduction (OR:1.062, 95%CI 1.039-1.086 P<0.001) and ESKD (OR:1.174, 95%CI 1.070-1.289, P = 0.001)., Conclusions: This real-word analysis in a large cohort of individuals with low-to-moderate cardiovascular risk suggests that moderate-to-severe elevation of plasma TG levels is associated with a significantly increased risk of long-term kidney function deterioration., Competing Interests: Declaration of Competing Interest R.

Background: The results of Aspirin prevention of colorectal adenomas in patients with familial adenomatous polyposis (FAP) are controversial., Methods: We conducted a biomarker-based clinical study in eight FAP patients treated with enteric-coated low-dose Aspirin (100 mg daily for three months) to explore whether the drug targets mainly platelet cyclooxygenase (COX)-1 or affects extraplatelet cellular sources expressing COX-isozymes and/or off-target effects in colorectal adenomas., Results: In FAP patients, low-dose Aspirin-acetylated platelet COX-1 at Serine529 (>70%) was associated with an almost complete inhibition of platelet thromboxane (TX) B 2 generation ex vivo (serum TXB 2 ). However, enhanced residual urinary 11-dehydro-TXB 2 and urinary PGEM, primary metabolites of TXA 2 and prostaglandin (PG)E 2 , respectively, were detected in association with incomplete acetylation of COX-1 in normal colorectal biopsies and adenomas. Proteomics of adenomas showed that Aspirin significantly modulated only eight proteins. The upregulation of vimentin and downregulation of HBB (hemoglobin subunit beta) distinguished two groups with high vs. low residual 11-dehydro-TXB 2 levels, possibly identifying the nonresponders and responders to Aspirin., Conclusions: Although low-dose Aspirin appropriately inhibited the platelet, persistently high systemic TXA 2 and PGE 2 biosynthesis were found, plausibly for a marginal inhibitory effect on prostanoid biosynthesis in the colorectum. Novel chemotherapeutic strategies in FAP can involve blocking the effects of TXA 2 and PGE 2 signaling with receptor antagonists.

In the last decade, novel oral anticoagulants (NOACs) have emerged as prominent therapeutic options in non-valvular atrial fibrillation (NVAF). We analysed the clinical burden and the switching rate between all available NOACs, and their dosage change over a period of 5 years in a representative population of patients with NVAF aged between 70 and 75 years. Methods and Results: This is a retrospective observational study on administrative databases, covering approximately 6.2 million health-assisted individuals by the Italian National Health System (around 11% of the entire Italian residents). Out of 4640 NVAF patients treated with NOACs and aged 70-75 years in 2017, 3772 (81.3%) patients were still in treatment with NOAC up to 2021 and among them, 3389 (73.0%) patients remained in treatment with the same NOAC during 2017-2021. In fact, 10.2% of patients switched NOAC type and 10.3% changed the dose of the same NOAC. Overall, after switching, the dabigatran and rivaroxaban groups lost, respectively, 13.5% and 2.8% of patients, while apixaban and edoxaban resulted in a relative percentage increase of 6.8% and 44.6% of patients, respectively. By a logistic regression analysis, the treatment with rivaroxaban, apixaban, and edoxaban (respect to dabigatran) was associated with a significant risk reduction of switch of 57%, 68%, and 44%, respectively. On the other hand, several features of high risk were associated with dose reduction. Conclusions. In our 5-year analysis of a large administrative database, a switching among NOACs or a change in NOAC dosages occurred in around 20% of elderly patients with NVAF. The type of NOAC was associated with a high switching rate, while several characteristics of high risk resulted as predictors of dose reduction of NOACs. Moreover, a worsening trend of clinical conditions occurred in patients maintaining the same NOAC treatment across 2017-2021.

This real-world analysis conducted on administrative databases of a sample of Italian healthcare entities was aimed at describing the role of therapeutic pathways and drug utilization in terms of adherence, persistence, and therapy discontinuation in HIV-infected patients under antiretroviral therapies (ART) and Tenofovir Alafenamide (TAF)-based regimens on healthcare resource consumption and related direct healthcare costs. Between 2015 and 2019, adults (≥18 years) prescribed with TAF-based therapies were identified and characterized in the year prior to the first prescription (index-date) for TAF-based therapies and followed-up until the end of data availability. Overall, 2658 ART-treated patients were included, 1198 of which were under a TAF-based regimen. TAF-based therapies were associated with elevated percentages of adherence (83.3% patients with proportion of days covered, PDC > 95% and 90.6% with PDC > 85%) and persistence (78.5%). The discontinuation rate was low in TAF-treated patients, ranging from 3.3% in TAF-switchers to 5% in naïve. Persistent patients had lower overall mean annual healthcare expenditures (EUR 11,106 in persistent vs. EUR 12,380 in non-persistent, p = 0.005), and this trend was statistically significant also for costs related to HIV hospitalizations. These findings suggest that a better therapeutic management of HIV infection might result in positive clinical and economic outcomes.

This real-world analysis evaluated the clinical and economic burden of non-dialysis-dependent CKD patients with and without secondary hyperparathyroidism (sHPT) in Italy. An observational retrospective study was conducted using administrative databases containing a pool of healthcare entities covering 2.45 million health-assisted individuals. Adult patients with hospitalization discharge diagnoses for CKD stages 3, 4, and 5 were included from 1 January 2012 to 31 March 2015 and stratified using the presence/absence of sHPT. Of the 5710 patients, 3119 were CKD-only (62%) and 1915 were CKD + sHPT (38%). The groups were balanced using Propensity Score Matching (PSM). Kaplan-Meier curves revealed that progression to dialysis and cumulative mortality had a higher incidence in the CKD + sHPT versus CKD-only group in CKD stage 3 patients and the overall population. The total direct healthcare costs/patient at one-year follow-up were significantly higher in CKD + sHPT versus CKD-only patients (EUR 8593 vs. EUR 5671, p < 0.001), mostly burdened by expenses for drugs (EUR 2250 vs. EUR 1537, p < 0.001), hospitalizations (EUR 4628 vs. EUR 3479, p < 0.001), and outpatient services (EUR 1715 vs. EUR 654, p < 0.001). These findings suggest that sHPT, even at an early CKD stage, results in faster progression to dialysis, increased mortality, and higher healthcare expenditures, thus indicating that timely intervention can ameliorate the management of CKD patients affected by sHPT.

Background: Platelet-cancer cell interactions modulate tumor metastasis and thrombosis in cancer. Platelet-derived extracellular vesicles (EVs) can contribute to these outcomes., Methods: We characterized the medium-sized EVs (mEVs) released by thrombin-stimulated platelets of colorectal cancer (CRC) patients and healthy subjects (HS) on the capacity to induce epithelial-mesenchymal transition (EMT)-related genes and cyclooxygenase (COX)-2( PTGS2 ), and thromboxane (TX)B 2 production in cocultures with four colorectal cancer cell lines. Platelet-derived mEVs were assessed for their size distribution and proteomics signature., Results: The mEV population released from thrombin-activated platelets of CRC patients had a different size distribution vs. HS. Platelet-derived mEVs from CRC patients, but not from HS, upregulated EMT marker genes, such as TWIST1 and VIM, and downregulated CDH1. PTGS2 was also upregulated. In cocultures of platelet-derived mEVs with cancer cells, TXB 2 generation was enhanced. The proteomics profile of mEVs released from activated platelets of CRC patients revealed that 119 proteins were downregulated and 89 upregulated vs. HS., Conclusions: We show that mEVs released from thrombin-activated platelets of CRC patients have distinct features (size distribution and proteomics cargo) vs. HS and promote prometastatic and prothrombotic phenotypes in cancer cells. The analysis of platelet-derived mEVs from CRC patients could provide valuable information for developing an appropriate treatment plan.

A real-world analysis among the Italian population has been carried out to estimate the number of atrial fibrillation (AF) patients undergoing catheter ablation and to evaluate their clinical outcome and economic burden. A retrospective analysis on administrative Italian databases has been performed. Between January 2011 and December 2019, all patients diagnosed with AF were considered and those undergoing catheter ablation were identified. Overall, 3084 (3.54%) of AF patients with at least one catheter ablation were included (mean age 63.2, 67.3% males). A significant decrease in the use of AF-related medications and in hospitalizations, mainly related to AF and heart failure, was observed during the 3-year post-ablation period. The average total cost per patient during the 1-year before ablation period was significantly higher compared to the 1-year post-ablation cost (EUR 5248 vs. 4008, respectively; p < 0.001). After propensity score matching, the overall mortality of patients who underwent ablation was significantly lower compared to that assessed in patients not treated with the procedure (9.386/1000 vs. 23.032/1000 person-year, respectively; p < 0.001). Moreover, the mean total costs were significantly higher in patients who did not undergo ablation compared to those who received ablation (EUR 5516 vs. 4008, respectively; p < 0.001). This real-world data analysis shows that in Italy, although catheter ablation is performed in a minority of AF patients, it is associated with significantly better post-procedure clinical outcomes and a significant reduction in healthcare-related costs.

Platelet-type lipoxygenase (pl12-LOX), encoded by ALOX12, catalyzes the production of the lipid mediator 12S-hydroperoxyeicosa-5,8,10,14-tetraenoic acid (12S-HpETE), which is quickly reduced by cellular peroxidases to form 12(S)-hydroxy-5,8,10,14-eicosatetraenoic acid (12S-HETE). Platelets express high levels of pl12-LOX and generate considerable amounts of 12S-HETE from arachidonic acid (AA; C20:4, n-6). The development of sensitive chiral liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods has allowed the accurate quantification of 12S-HETE in biological samples. Moreover, advances in the knowledge of the mechanism of action of 12S-HETE have been achieved. The orphan G-protein-coupled receptor 31 (GPR31) has been identified as the high-affinity 12S-HETE receptor. Moreover, upon platelet activation, 12S-HETE is produced, and significant amounts are found esterified to membrane phospholipids (PLs), such as phosphatidylethanolamine (PE) and phosphatidylcholine (PC), promoting thrombin generation. Platelets play many roles in cancer metastasis. Among them, the platelets' ability to interact with cancer cells and transfer platelet molecules by the release of extracellular vesicles (EVs) is noteworthy. Recently, it was found that platelets induce epithelial-mesenchymal transition(EMT) in cancer cells, a phenomenon known to confer high-grade malignancy, through the transfer of pl12-LOX contained in platelet-derived EVs. These cancer cells now generate 12-HETE, considered a key modulator of cancer metastasis. Interestingly, 12-HETE was mainly found esterified in plasmalogen phospholipids of cancer cells. This review summarizes the current knowledge on the regulation and functions of pl12-LOX in platelets and cancer cells and their crosstalk.Novel approaches to preventing cancer and metastasis by the pharmacological inhibition of pl12-LOX and the internalization of mEVs are discussed., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Inc.

Anaemia is a uraemia-related complication frequently found in non-dialysis-dependent chronic kidney disease (ND-CKD) patients, with iron-deficiency anaemia (IDA) as the main underlying mechanism. Given the suboptimal anaemia management in ND-CKD patients with a co-diagnosis of IDA, this study evaluated the role of IDA therapy on clinical outcomes and healthcare resource consumptions in an Italian clinical setting. A retrospective observational real-world analysis was performed on administrative databases of healthcare entities, covering around 6.9 million health-assisted individuals. From January 2010 to March 2019, ND-CKD patients were included and diagnosed with IDA in the presence of two low-haemoglobin (Hb) measurements. Patients were divided into IDA-treated and untreated, based on the prescription of iron [Anatomical-Therapeutic Chemical (ATC) code B03A] or anti-anaemia preparations (ATC code B03X), and evaluated during a 6-month follow-up from the index date [first low haemoglobin (Hb) detection]. IDA treatment resulted in significantly decreased incidence of all cause-related, cardiovascular-related, and IDA-related hospitalizations (treated vs. untreated: 44.5% vs. 81.8%, 12.3% vs. 25.3%, and 16.2% vs. 26.2%, respectively, p < 0.001). A healthcare direct cost estimation showed that overall mean expenditure per patient reduced by 47% with IDA treatment (5245€ vs. 9918€, p < 0.001), mainly attributable to hospitalizations (3767€ vs. 8486€, p < 0.001). This real-life analysis on Italian ND-CKD-IDA patients indicates that IDA therapy administration provides significant benefits in terms of patients’ clinical outcomes and healthcare cost savings.

Introduction: Real-world pharmacoutilization analysis of biological drugs in psoriatic arthritis (PsA) patients with the aim to evaluate biologic treatment patterns and pharmacoutilization among patients with PsA in Italy., Methods: A retrospective study was conducted using administrative databases of Italian Entities. PsA patients were included and diagnosed by hospitalization and/or an active exemption code. Two analyses were performed: a cross-sectional for treatment patterns in patients enrolled among 2017-2020, and a longitudinal study during 2015 to investigate the pharmacoutilization, in terms of persistence and monthly maintenance dosage of biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Patients with or without b/tsDMARDs prescriptions before inclusion were defined as bioexperienced or naïve, respectively. An analysis on ixekizumab-treated patients (IXE patients) from the 2017-to study ending was performed., Results: PsA was diagnosed in 24,786 (2017), 27,221 (2018), 28,889 (2019), and 29,292 (2020) patients. Across 2017-2020, 31.1-40.5% of PsA patients were untreated with systemic medications, and 16.4-18.8% were under biological therapies. Among b/tsDMARD-treated patients, decreasing use of TNF-inhibitors (77.6-57.1%) and increasing IL-inhibitors (19.6-33.2%) was found across 2017-2020, respectively. Persistence to TNF-inhibitors and IL inhibitors as first-line ranged, respectively, 74.9-83.0% and 73.0-84.6%; specifically, 73.1-76.9% and 73.0-83.8% among bio-naïve, 83.3-90.0%, and 87.0% among bio-experienced. Among IXE-patients (N = 178), 55.6% were bio-naïve, while 21.9% previously used secukinumab, 12.9% adalimumab, 10.1% etanercept. During a 1-year follow-up, 6.8% of IXE patients switched therapy., Conclusions: This real-world study of PsA pharmacoutilization in Italy showed that more than one-third of patients were systemically untreated, and almost 20% were receiving biological medications. Among biological users, increasing use of IL-inhibitors and a decrease in TNF-inhibitors prescriptions over the years were found. A rather-high extent of persistency in treatment was observed. A focused analysis on IXE patients revealed over half of them to be bio-naïve, while around one-fourth were bio-experienced to IL inhibitors., (© 2022. The Author(s).)
