Defining distal splenopancreatectomy by the mesopancreas

BACKGROUND

The implementation of the pathologic CRM (circumferential resection margin) staging system for pancreatic head ductal adenocarcinomas (hPDAC) resulted in a dramatic increase of R1 resections at the dorsal resection margin, presumably because of the high rate of mesopancreatic fat (MP) infiltration. Therefore, mesopancreatic excision (MPE) during pancreatoduodenectomy has recently been promoted and has demonstrated better local disease control, fueling the discussion of neoadjuvant downsizing regimes in MP + patients. However, it is unknown to what extent the MP is infiltrated in patients with distal pancreatic (tail/body) carcinomas (dPDAC). It is also unknown if the MP infiltration status affects surgical margin control in distal pancreatectomy (DP). The aim of our study was to histopathologically analyze MP infiltration and elucidate the influence of resection margin clearance on recurrence and survival in patients with dPDAC. Furthermore, the results were compared to a collective receiving MPE for hPDAC.

METHOD

Clinicopathological and survival parameters of 295 consecutive patients who underwent surgery for PDAC (n = 63 dPDAC and n = 232 hPDAC) were evaluated. The CRM evaluation was performed in a standardized fashion and the specimens were examined according to the Leeds pathology protocol (LEEPP). The MP area was histopathologically evaluated for cancerous infiltration.

RESULTS

In 75.4% of dPDAC patients the MP fat was infiltrated by vital tumor cells. The rates of MP infiltration and R0CRM- resections were similar between dPDAC and hPDAC patients (p = 0.497 and 0.453 respectively). MP- infiltration status did not correlate with CRM implemented resection status in dPDAC patients (p = 0.348). In overall survival analysis, resection status and MP status remained prognostic factors for survival. In follow up analysis. surgical margin clearance in dPDAC patients was associated with a significant improvement in local recurrence rates (5.2% in R0CRM- resected vs. 33.3 in R1/R0CRM + resected, p = 0.002).

CONCLUSION

While resection margin status was not affected by the MP status in dPDAC patients, the high MP infiltration rate, as well as improved survival in MP- dPDAC patients after R0CRM- resection, justify mesopancreatic excision during splenopancreatectomy. Larger scale studies are urgently needed to validate our results and to study the effect on neoadjuvant treatment in dPDAC patients.

MRI in-bore biopsy following MRI/US fusion-guided biopsy in patients with persistent suspicion of clinically significant prostate cancer

PURPOSE

Patients with suspicion of clinically significant prostate cancer (csPC) on multiparametric prostate MRI (mpMRI) but negative or inconclusive MRI/US fusion-guided biopsy (FB) can be challenging in clinical practice. To assess the utility of MRI in-bore biopsy (IB) in patients with discordant imaging and histopathological findings after FB.

METHODS

Consecutive patients with Prostate Imaging Reporting and Data System (PI-RADS) category 4 or 5 on mpMRI at 3T after FB without histologically confirmed csPC who underwent IB between 01/2014 and 05/2022, were retrospectively included. The primary objective was to assess the detection rate of csPC. Secondary objectives were to analyze clinical parameters, MRI parameters, and lesion localization.

RESULTS

In the final cohort of 51 patients, the IB resulted in an overall detection rate of 71% for PC and 47% for csPC. Furthermore, in 55% of cases with initial low-grade PC, the Gleason score was upgraded after IB. CsPC was often detected apical and/or anterior. The detection rate for PC was 58% in PI-RADS category 4 and 94% in PI-RADS category 5 (csPC 39% and 61%, respectively). Patients with csPC had statistically significant smaller prostate volumes, a higher PI-RADS category, a higher prostate-specific antigen density (PSAD), and were older.

CONCLUSIONS

For a relevant proportion of patients with PI-RADS category 4 or 5 and negative or inconclusive findings on previous FB, but with persistent suspicion of csPC, a subsequent IB verified the presence of csPC. Therefore, IB can be a backup in cases of uncertainty.

Primary Sjögren's syndrome in Italy: Real-world evidence of a rare disease through administrative healthcare data

OBJECTIVES

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease with significant impact on morbidity, mortality, and quality of life. This study aimed to evaluate epidemiology, healthcare needs and related costs of pSS patients from the Italian National Health Service perspective.

METHODS

From the Fondazione Ricerca e Salute's database (∼5 million inhabitants/year), pSS prevalence in 2018 was calculated. Demographics, mean healthcare consumptions and direct costs at one year following index date (first in-hospital diagnosis/disease waiver claim) were analysed through an individual direct matched pair case-control analysis (age, sex, residency).

RESULTS

In Italy, 3.8/10,000 inhabitants were identified as affected by pSS (1,746 case: 1,746 controls) in 2018. In the year following index date, 53.7% of cases and 42.7% of controls received ≥1 drug (p<0.001); mean per capita cost was €501 and €161, respectively (p<0.01). At least one hospitalization occurred to 7.8% of cases and 3.9% of controls (p<0.001) with mean per capita costs of €416 and €129, respectively (p = 0.46). At least one outpatient specialist service was performed in 49.8% of cases and 30.6% of controls (p<0.001); mean per capita costs were €200 and €75, respectively (p<0.01). Overall, mean annual costs were €1,171 per case and €372 per control (p < 0.01).

CONCLUSION

According to results of this population-based study, the prevalence of pSS in Italy appears to be consistent with the definition of rare disease. Patients with pSS have higher pharmacological, in-hospital and outpatient specialist care needs, leading to three-times higher overall cost for the INHS, compared to the general population.

Italian healthcare resource consumption for patients on hemodialysis treated for chronic kidney disease-associated pruritus (CKD-aP)

Background

Chronic kidney disease-associated pruritus (CKD-aP) affects patients on hemodialysis. This study identified hemodialysis patients presumably affected or not affected by CKD-aP and integrated healthcare costs, from the perspective of the Italian administrative healthcare data.

Methods

Through cross-linkage of Italian administrative healthcare data collected between 2015 and 2017 (accrual period) in the database of Fondazione ReS (Ricerca e Salute), patients undergoing in-hospital/outpatient hemodialysis were selected. Cohorts with and without CKD-aP were created based on the presence/absence of CKD-aP-related treatment (according to common clinical practice and guidelines) supplies and assessed in terms of CKD-aP-related treatments and mean healthcare costs per capita paid by the Italian National Health Service (INHS).

Results

Of 1,239 people on hemodialysis for ≥2 years, CKD-aP affected 218 patients. Patients with CKD-aP were older and with more comorbidities. During the follow-up year, on average, the INHS spent €37,065 per case, €31,286 per control and € 35,988 per non-CKD-aP subject. High-efficiency dialytic therapies performed to people on hemodialysis with CKD-aP largely weighed on the overall mean annual cost.

Conclusions

This real-world study identified patients on chronic hemodialysis potentially treated for CKD-aP. Interestingly, high-efficiency dialysis seems the most frequent and expensive choice for the treatment of CKD-aP. The discovery of appropriate and effective treatments for this condition might offer cost offsets.

Novel potassium binders to optimize RAASi therapy in heart failure: A systematic review and meta-analysis

AIMS

Hyperkalemia often occurs among heart failure (HF) patients, particularly when treated with renin-angiotensin-aldosterone system inhibitors (RAASi). Even modest potassium levels variations raise the risk of mortality and prompt patients to discontinue disease-modifying treatment, as RAASi. Novel potassium binders (NPB), patiromer and sodium zirconium cyclosilicate, are effective in reducing potassium levels and are approved for the treatment of hyperkalemia in HF, but whether their use results in a real optimization of HF treatment remains to be seen. The aim of the present meta-analysis was to assess the efficacy of NPB on the optimization of RAASi therapy in HF patients.

METHODS AND RESULTS

PubMed, Web of Science and Clinicaltrial.gov were searched without restrictions from inception to 06 August 2022 to identify valuable articles. The studies that met the inclusion criteria were analyzed. The prespecified primary outcome was the optimization of RAASi therapy in HF patients, defined as the proportion of patients on RAASi at the end of follow-up. Secondary outcomes were hyperkalemia events, reduction in potassium levels, and adverse drugs reactions. Six studies with a total of 1390 patients were included. NPB improved RAASi therapy optimization in HF by 14% (95% CI: 4-26%), decreased hyperkalemia events by 29% (95% CI: 55-92%), and reduced potassium levels by 0.31 mEq/L (95% CI: 0.18-0.44) compared to placebo, maintaining a good safety profile.

CONCLUSION

NPB are effective in allowing RAASi therapy optimization in patients affected by HF, in reducing hyperkalemia events and potassium levels.

Multiparametric MRI characteristics of prostatitis and atrophy in the peripheral zone in men without prostate cancer

PURPOSE

To analyse multiparametric magnetic resonance imaging (mpMRI) characteristics and appearance of histopathologically proven non-cancerous intraprostatic findings focussing on quantity of prostatitis and atrophy in the peripheral zone.

METHOD

In this retrospective analysis consecutive patients with mpMRI followed by MRI/TRUS-fusion biopsy comprising targeted (TB) and systematic biopsy (SB) cores without prostate cancer (PC) at histopathology were included. Subgroup analysis was performed in younger men (≤50 years). The proportions of prostatitis and atrophy were quantified for each biopsy core based on histopathology. MRI findings in the peripheral zone (PZ) and index lesions (IL, most suspicious/representative lesion) were characterized regarding changes in T2w, ADC value, and enhancement of dynamic contrast enhancement (DCE) and correlated with quantity of prostatitis and atrophy.

RESULTS

Seventy-two patients were analysed. The median baseline characteristics were PSA 5.4 ng/ml (4.0-7.9), PI-RADS classification 3 (2-4), prostate volume 43 ml (33-57), and PSA density 0.13 ng/ml2 (0.10-0.19). Prostatitis was found in 44 % (n = 32) and atrophy in 65 % (n = 47) of cases. The quantity of atrophy demonstrated a significant correlation to T2w changes, ADC increase and DCE enhancement (p = 0.05, p = 0.05, p = 0.01), whereas quantity of prostatitis did not show any significant correlation to the MRI changes (p = 0.68, p = 0.58, p = 0.95). Quantity of prostatitis and atrophy increased with PI-RADS classification. Younger men had lower PSA (4.4 vs. 7.8 ml/ng; p < 0.001), smaller prostate volume (40 vs. 59 ml; p = 0.001), and lower PI-RADS classification (2-3 vs. 3-4; p = 0.005) and prostatitis and atrophy were less frequently observed (p ≤ 0.01, p = 0.03).

CONCLUSIONS

Quantity of atrophy and prostatitis had different influence on MRI characteristics and increased within higher PI-RADS classification. Younger men had diffuse hypointense changes at T2w images, but less quantity of prostatitis and atrophy.

Acute myeloid leukemia: Incidence, transplantation and survival through Italian administrative healthcare data

OBJECTIVE

To identify newly diagnosed patients with acute myeloid leukemia in 2017 treated with intensive chemotherapy or unfit for intensive chemotherapy, and to assess their probability of receiving allogeneic stem cell transplantation and survival, from the Italian National Health Service perspective.

PATIENTS AND METHODS

From the Ricerca e Salute database, adults with an in-hospital diagnosis of acute myeloid leukemia (International Classification of Disease-9th version-Clinical Modification code 205.0x) in 2017 (index date), without any identifying acute myeloid leukemia criteria within the preceding year, were selected. Among them, subjects treated with intensive chemotherapy (chemotherapy during an overnight hospitalization) within one year after index date were identified. The remaining were considered unfit for intensive chemotherapy. Gender, age and comorbidities were described. Within the follow-up period, probabilities of in-hospital allogeneic stem cell transplantation and overall survival were assessed through Kaplan Meier analyses.

RESULTS

From 4,840,063 beneficiaries of the Italian National Health Service, 368 newly acute myeloid leukemia diagnosed adults (9.0 *100,000) were selected. Males comprised 57%. Mean age was 68±15. There were 197 patients treated with intensive chemotherapy. The remaining 171 unfit for intensive chemotherapy were older (72±14) and with more comorbidities (e.g. hypertension, chronic lung diseases and chronic kidney disease). Only patients treated with intensive chemotherapy underwent an allogeneic stem cell transplantation (41; 33%) during the one year after the index date. Within the first and second follow-up year, respectively: 41.1% and 26.9% of subjects treated with intensive chemotherapy (144) survived (median survival time: 7.8 months); 25.7% and 18.7% of those unfit for intensive chemotherapy (139) survived (1.2 months). Difference was significant (p<0.0001). Within one and two years after transplantation (41 patients), 73.5% and 67.3% of subjects survived, respectively.

CONCLUSION

This study, by showing the incidence of acute myeloid leukemia in Italy in 2017, the proportion of patients treated with intensive chemotherapy from the new diagnosis, the use of allogeneic stem cell transplantation and two-year survival, integrated evidence on large and unselected populations and may help to improve treatment strategies of older acute myeloid leukemia patients.

Effects of sacubitril/valsartan on exercise capacity: a prognostic improvement that starts during uptitration

PURPOSE

Sacubitril/valsartan is a mainstay of the treatment of heart failure with reduced ejection fraction (HFrEF); however, its effects on exercise performance yielded conflicting results. Aim of our study was to evaluate the impact of sacubitril/valsartan on exercise parameters and echocardiographic and biomarker changes at different drug doses.

METHODS

We prospectively enrolled consecutive HFrEF outpatients eligible to start sacubitril/valsartan. Patients underwent clinical assessment, cardiopulmonary exercise test (CPET), blood sampling, echocardiography, and completed the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Sacubitril/valsartan was introduced at 24/26 mg b.i.d. dose and progressively uptitrated in a standard monthly-based fashion to 97/103 mg b.i.d. or maximum tolerated dose. Study procedures were repeated at each titration visit and 6 months after reaching the maximum tolerated dose.

RESULTS

Ninety-six patients completed the study, 73 (75%) reached maximum sacubitril/valsartan dose. We observed a significant improvement in functional capacity across all study steps: oxygen intake increased, at peak exercise (from 15.6 ± 4.5 to 16.5 ± 4.9 mL/min/kg; p trend = 0.001), while minute ventilation/carbon dioxide production relationship reduced in patients with an abnormal value at baseline. Sacubitril/valsartan induced positive left ventricle reverse remodeling (EF from 31 ± 5 to 37 ± 8%; p trend < 0.001), while NT-proBNP reduced from 1179 [610-2757] to 780 [372-1344] pg/ml (p trend < 0.0001). NYHA functional class and the subjective perception of limitation in daily life at KCCQ-12 significantly improved. The Metabolic Exercise Cardiac Kidney Index (MECKI) score progressively improved from 4.35 [2.42-7.71] to 2.35% [1.24-4.96], p = 0.003.

CONCLUSIONS

A holistic and progressive HF improvement was observed with sacubitril/valsartan in parallel with quality of life. Likewise, a prognostic enhancement was observed.

[The population affected by neovascular age-related macular degeneration and treated with anti-Vegf through Italian administrative healthcare data.]

INTRODUCTION

The neo-vascular age-related macular degeneration (nAmd) is a frequent cause of vision loss, although the intravitreal (Ivt) injections of anti-Vegf (vascular endothelial growth factor) have improved functional outcomes. This study has assessed the healthcare and economic burden on the Italian national health service (Inhs) for patients with nAmd and new users of anti-Vegf.

METHODS

From the database of Fondazione Ricerca e Salute (ReS), people aged ≥55 and with an in-hospital diagnosis of nAmd and/or an injection of anti-Vegf (aflibercept, ranibizumab, pegaptanib; index date) in 2018 are selected. Those with other conditions treated with anti-Vegf and with an Ivt injection before 2018 are excluded. New users of anti-Vegf are analyzed by sex, age, comorbidities, Ivt administrations, switch of anti-Vegf, local outpatient specialist services (with some focuses) and direct healthcare costs charged to the Inhs Results. In 2018, of 8125 inhabitants aged ≥55 with nAmd (4.6x1000 inhab.; mean age 76±9; F: 50%), 1513 (19%) are new users of Ivt anti-Vegf (mean age 74±9), whose incidence (0.9x1000) increased with age until 84 years old. A proportion of 60.7% had ≥2 comorbidities (mainly hypertension, dyslipidemia and diabetes). Within the 2nd follow-up year, only 598 patients are still treated (60% were lost). On average, 4.8 Ivt injections in the first and 3.1 in the second year are registered. On average, the total cost charged to the Inhs per new user of anti-Vegf was € 6726 (Ivt anti-Vegf accounted for the 76%) and € 3282 (hospitalizations for causes different from nAmd accounted for the 47%), during the first and the second year, respectively.

CONCLUSIONS

This analysis suggests that in Italy people with nAmd and new users of anti-Vegf are elderly, affected by many comorbidities, treated with Ivt anti-VEGF less than what is required and authorized to achieve a benefit, undergo very few follow-up outpatient specialist visits and tests and, within the 2nd year, their hospitalizations for causes different from nAmd mainly weighs on the total expenditure charged to the Inhs.

Left atrium decompression devices across the spectrum of ejection fraction in heart failure: an updated systematic review and meta-regression analysis

BACKGROUND

In patients affected by heart failure (HF) with reduced ejection fraction (HFrEF), pharmacological treatments have been proven to alleviate symptoms and improve prognosis, while no treatment other than sodium-glucose co-transporter-2 inhibitors have demonstrated significant effects in HF with preserved ejection fraction (HFpEF). Left atrium decompression devices (LADd) have been recently investigated as a new interventional approach in patients with HFpEF.

OBJECTIVES

To assess the efficacy of LADd on soft endpoints in HF patients across the spectrum of ejection fraction.

METHODS

PubMed and Web of Science were searched without restrictions from inception to 28 May 2022 to identify valuable articles. The studies that met the inclusion criteria were analyzed. The prespecified main outcomes were the change from baseline in 6-min walking distance (6MWD), NYHA class and health-related quality of life (HRQoL). Secondary outcomes were reduction in HF hospitalizations, echocardiographic, and hemodynamic parameters.

RESULTS

Eleven studies, with a total of 547 patients, were included. LADd significantly improved 6MWD by 43.95 m (95% CI 29.64-58.26 m), decreased NYHA class by 0.93 (95% CI 1.20-0.67), and improved HRQoL questionnaire by 20.45 points (95% CI 13.77-27.14) with better results for all outcomes in patients with lower EFs.

CONCLUSION

The present meta-analysis suggests that LADd are favorable in improving 6MWD, NYHA class, and HRQoL in HF across a wide spectrum of ejection fraction, with better outcomes in patients with lower EFs.

[Community acquired pneumoniae and chronic obstructive pulmonary disease: the RWE analysis of events that required hospitalizations, and healthcare integrated costs.]

INTRODUCTION

The community-acquired pneumonia (Cap) and the acute exacerbation of chronic obstructive pulmonary disease (Aecopd) frequently receive wrong therapies, leading to the increase of healthcare consumption resources, direct and indirect costs, and antimicrobial resistance. This study identified Cap and Aecopd hospitalized events, and analyzed them in terms of comorbidities, antibiotic use, re-hospitalizations, diagnostics and costs, from the perspective of the Italian national health service (Inhs).

METHODS

From the database of Fondazione Ricerca e Salute (ReS), hospitalizations for Cap and Aecopd from 2016 to 2019. Demographics, comorbidities and mean in-hospital stay at the baseline, antibiotics reimbursed by the Inhs within 15 days before and after the index event, outpatient diagnostics performed before the event and in-hospital diagnostics, and direct costs charged to the Inhs, are assessed.

RESULTS

From 2016 to 2019 (~5 million inhabitants/year), 31,355 events of Cap (1.7x1000/year) and 42,489 events of Aecopd (4.3x1000 inhabitants aged ≥45/year) were identified, of which 32% and 26.5%, respectively, were treated with antibiotics before the hospitalization. The highest frequency of hospitalizations and comorbidities, and the longest mean in-hospital stays are found among elderly. Events not treated before and after the hospitalization showed the longest in-hospital stay. More than 12 Ddd (defined daily dose) are dispensed after the discharge. Local outpatient diagnostics are performed before the admission to <1% of the events; in-hospital diagnostics are registered in 5.6% and 1.2% of Cap and Aecopd, respectively, discharge forms. About 8% and 24% of Cap and Aecopd, respectively, are re-hospitalized during one subsequent year, mainly within one month. The mean expenditures per event of Cap and Aecopd were € 3646 and € 4424, respectively: hospitalizations, antibiotics and diagnostics accounted for the 99%, 1% and <0.1% of the total expense, respectively.

CONCLUSIONS

This study provided a very high dispensation of antibiotics after the hospitalization for Cap and Aecopd, while a very low use of differential diagnostics available within the observed periods, to the detriment of the enforcement actions proposed at institutional levels.

[Occurrence of cardiovascular events within a large population of patients affected by rheumatoid arthritis with or without diabetes.]

INTRODUCTION

Rheumatoid arthritis (Ra) and diabetes are often associated with chronic multimorbidity and share the high risk of development of major cardiovascular events (Mace). This study aimed to identify and analyse patients with only Ra, Ra + diabetes, and only diabetes, in terms of comorbidities and new occurrence of Cv events, from the perspective of the Italian national health service (Inhs).

METHODS

Starting from the Fondazione ricerca e salute (ReS)'s database, through the record linkage of administrative healthcare data, cohorts with only Ra, Ra + diabetes and only diabetes have been selected, characterized (age and sex), and analysed by comorbidity (depression, dyslipidemia, hypertension, hemorrhagic stroke and ischemic stroke/transient ischemic attack - Tia, coronary artery disease - Cad, heart failure - Hf, chronic liver disease, periphery artery disease - Pad, chronic kidney disease, asthma/chronic obstructive pulmonary disease - Copd, neoplasia) and by new Cv events (Hf, Cad and ischemic stroke/Tia) within two follow-up years (Kaplan-Meier curves). A logistic regression model defined contribution and type of association of some variables on new Cv events.

RESULTS

In 2018, from 5.375.531 Inhs beneficiaries in the ReS database, 13.698 (0.25%) were affected by only Ra, 1728 (0.03%) by Ra + diabetes, 347,659 (6.8%) by only diabetes. The only Ra cohort was composed by more females, younger and with less comorbidities patients. Proportions of 79.3%, 70.8% and 38.5% of patients with Ra + diabetes, only diabetes and only Ra were affected by 2 to ≥4 comorbidities: among patients with Ra + diabetes, comorbidities showed the highest frequencies, mainly hypertension, dyslipidemia and asthma/Copd. Within two follow-up years, about 8% of patients with diabetes with/without Ra developed a new Cv event (vs 3% with only Ra). The presence of Ra/diabetes or Ra + diabetes, male sex, older age and comorbidities of interest resulted significantly (p<0.01) associated with a higher Cv risk.

CONCLUSIONS

Comorbidities and the co-presence of diabetes in patients with Ra determine a complicated framework with high risk of Cv events. It is worthy include more complex patients in clinical trials, in order to generate evidence useful for even more multidisciplinary medical teams.

[A view of care pathways approved by Italian Regions, to face the challenge of the community-based healthcare: a quali-quantitative analysis of the Pdta Net database.]

INTRODUCTION

The adoption of a Care Pathway (CP) allows the healthcare management of patients suffering from high-epidemiological impact chronic diseases. The continuity of care of these patients is one of the main purposes of the community-based healthcare reform, foreseen in the 6th Mission of the National recovery and resilience plan. Fondazio-ne Ricerca e Salute (ReS) collects and analyses regional CPs approved in Italy, through the Pdta Net database.

METHODS

Fondazione ReS has retrieved all the CPs approved by Italian Regions and Autonomous provinces until 12/31/2021 within institutional websites, through specific keywords. The quali- and quantitative analysis of CPs was based on the approving Region, the publication year, the disease (distinguishing between high-epidemiological impact chronic diseases and rare conditions) and clinical area. Following the 5-year experience gained by Fondazione ReS in terms of CPs' aims and organization for the full realization of an evidence-based healthcare of chronic patients, all data collected until 12/31/2021 underwent an in-depth double-blinded quality control. This control was aimed to make the Pdta Net database as representative as possible of the existing documents closest to a real CP.

RESULTS

From 2005 to 2021, 729 regional CPs have been approved: 404 on high-impact chronic diseases and 220 on rare conditions. The CPs of chronic diseases, mostly edited by Piemonte (45 CPs), Campania (34) and Toscana (33) Regions, mainly concern on diabetes (19), chronic obstructive pulmonary disease (15), heart failure (13), stroke, multiple sclerosis and colorectal neoplasms (12 each one), breast cancer (11), dementia and chronic kidney disease (10 each one). Most of the CPs on rare diseases have been edited by Regions with an established Rare Disease Network, i.e., Lombardia (125 CPs), Lazio (74) and Toscana (40): neurology (61) and oncology (52) were the most represented clinical areas.

CONCLUSIONS

The high number of CPs approved in Italy confirms an increasing interest of the healthcare institutions. The collected CPs show an extreme variety of titles, text structures and disease choices. Given the absence of an institutional observatory and of devotees of shared and harmonized CPs, annually Pdta Net makes available an updated and complete overview of these governance tools, which are essential for the upcoming changes of the Italian national health service.

467 EFFICACY OF TRANSCATHETER INTERATRIAL SHUNT DEVICES IN HEART FAILURE: A SYSTEMATIC REVIEW AND META-ANALYSIS

Background

In patients affected by heart failure with reduced ejection fraction (HFrEF), pharmacological treatments have been proven to alleviate symptoms and improve prognosis, while no treatment other than sodium-glucose co-transporter-2 inhibitors have demonstrated significant effects in HF with preserved ejection fraction (HFpEF). Left-to-right interatrial shunt devices are now being investigated for left atrial decompression in patients with HF.

Objectives

To assess the efficacy of left-to-right interatrial shunt devices (IASD) on soft endpoints in HF patients.

Methods

PubMed and Web of Science were searched without restrictions from inception to 28 May 2022 to identify valuable articles. The studies that met the inclusion criteria were analyzed. The prespecified main outcomes were the change from baseline in 6-minute walking distance (6MWD), NYHA class and health-related quality of life (HRQoL). Secondary outcomes were reduction in HF hospitalizations, and echocardiographic and hemodynamic parameters.

Results

Ten studies, with a total of 539 patients were included. IASD significantly improved 6MWD of 44.19 m (95% CI: 29.82–58.56 m), decreased NYHA class by 0.89 (95% CI: 1.10–0.67), and improved HRQoL questionnaire by 20.19 points (95% CI: 12.94–27.44) with better results for all outcomes in younger patients and in patients with lower EFs (Figure).

Conclusion

The present meta-analysis suggests that IASD are favorable in improving 6MWD, NYHA class, and HRQoL in HF across a wide spectrum of ejection fraction, with better outcomes in younger patients and in patients with lower EFs.

488 NOVEL POTASSIUM BINDERS IMPROVES RAASI THERAPY OPTIMIZATION IN HEART FAILURE: A SYSTEMATIC REVIEW AND META-ANALYSIS

Background

Hyperkalemia (HK) often occurs among patients with heart failure (HF), particularly when treated with renin-angiotensin-aldosterone system inhibitors (RAASi). Even modest variations from normal potassium levels raise the risk of mortality and prompt patients to limit or cease disease-modifying treatment. Novel potassium binders (NPB), patiromer and sodium zirconium cyclosilicate, are approved for treatment of HK, but whether this results in a real optimization of HF treatment remains to be seen.

Objectives

To assess the efficacy of NPB on the persistence of therapy with RAASi in HF patients.

Methods

PubMed and Web of Science were searched without restrictions from inception to 06 August 2022 to identify valuable articles. The studies that met the inclusion criteria were analyzed. The prespecified main outcome was the proportion of HF patients achieving target dose of RAASi. Secondary outcomes were the reduction in potassium levels, hyperkalemia events and persistence of therapy with RAASi in the overall population.

Results

Eight studies, with a total of 2247 patients were included. NPB improved optimization of RAASi therapy in HF compared to placebo by 21% (95% CI: 5% – 39%), decreased potassium levels by 0.48 mEq/L (95% CI: 0.28–0.67) and decreased hyperkalemia events by 53% (95% CI: 34% – 64%) and improved the proportion of the overall study population on RAASi therapy by 28% (95% CI: 7% – 52%).

Conclusion

The present meta-analysis suggests that NPB are favorable in improving the proportion of patients on RAASi therapy, whether they have HF or not, in reducing potassium levels and hyperkalemia events.

Acute lower respiratory infections: real-world evidence of antibiotic prescription pattern and costs from a large administrative Italian database

OBJECTIVE

This observational retrospective analysis aimed to describe antibiotic prescription pattern in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and community-acquired pneumonia (CAP) and their costs, from the Italian National Health Service perspective.

METHODS

From the ReS database, a cross-linkage of Italian healthcare administrative databases through a unique anonymous code allowed to select subjects aged ≥12 years, supplied with at least an antibacterial for systemic use (ATC code: J01) from 01/01/2017 to 12/31/2017 and evaluable until the end of 2018. Prescriptions of different antibiotics on the same date were excluded. The prescription pattern was assessed for patients with an AECOPD (aged ≥50) or a CAP event (aged ≥12) in 2017. A 30-day cost analysis after the antibacterial supply and according to absence/presence (15 days before/after the supply) of AECOPD/CAP hospitalization was performed.

RESULTS

In 2017, among patients aged ≥12 (~5 million), 1,845,268 were supplied with ≥1 antibacterial (37.2%). Antibacterial prescriptions potentially related to AECOPD were 39,940 and 4,059 to CAP: quinolones were the most prescribed (37.2% and 39.0%, respectively), followed by third-generation cephalosporins (25.5%; 27.5%), penicillins (15.4%; 14.9%), and macrolides (14.4%; 11.3%); the 30-day mean cost was €709 and €2,889. An association AECOPD/CAP-antibacterial supply costed more when the hospitalization occurred 15 days after the antibiotic supply (€5,006 and €4,966, respectively).

CONCLUSIONS

Findings confirmed the very high use of antimicrobials in Italy and highlighted the urgent need of improving current prescribing practices and developing new molecules, to stop the incessant spread of antimicrobial resistance and related socioeconomic impacts.

Prescription Pattern of Monoamine Oxidase B Inhibitors Combined with Levodopa: A Retrospective Observational Analysis of Italian Healthcare Administrative Databases

Background

Parkinson’s disease is still incurable, and several factors are considered when defining pharmacological therapy.

Objective

The aim of this study was to describe the prescription pattern of monoamine oxidase B inhibitors (MAO-BIs) marketed in Italy (selegiline, rasagiline, safinamide) as an add-on to levodopa among new users of MAO-BIs, from the perspective of the Italian National Health Service.

Patients and Methods

Through cross-linkage of administrative healthcare data in the Ricerca e Salute (ReS) database, adults with a supply of one or more MAO-BIs in 2017, and with no other MAO-BI use since 2013, were selected. Levodopa had to be supplied within 30 days before/after the MAO-BI. The incidence, use, sex, age, comorbidities, 2-year prescription patterns (i.e., switches, proportion of treated patients per semester/year, mean daily milligrams/monthly tablets supplied, discontinuation, change to other anti-Parkinson drug) of patients taking MAO-BIs were provided.

Results

In 2017, 1059 new users received an MAO-BI (incidence 22.6 × 100,000 adults) combined with levodopa: 502 subjects (10.7 × 100,000) were treated with selegiline, 161 (3.4 × 100,000) were treated with rasagiline, and 396 (8.4 × 100,000) were treated with safinamide. The cohorts mainly consisted of males with a median age of ≥ 74 years. Treatment incidences increased with age. Switches occurred in 18.0%, 11.0%, and 4.3% of the selegiline, rasagiline, and safinamide cohorts, respectively. Most of the patients switching from selegiline/safinamide changed to rasagiline, while most of the patients switching from rasagiline changed to safinamide. From the first to second years, patient numbers reduced by ≤ 50%, and the daily milligrams/monthly tablets slightly increased. Six-month discontinuation occurred in > 50% of all cohorts, and ≥ 65% of discontinuing patients changed to another anti-Parkinson drug.

Conclusions

This analysis described the heterogeneous use of MAO-BIs as an add-on to levodopa in Italy. Further clinical trials and real-world studies are encouraged to update the few existing guidelines and to align clinical practice strategies.

Secondary prevention of coronary artery disease: a retrospective observational analysis of italian healthcare administrative data

Funding Acknowledgements

Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): ACARPIA Farmaceutici S.r.l.

Background/Introduction

Prevalence and mortality rates in patients with a documented coronary artery disease (CAD) are high, mainly due to the suboptimal adherence to the recommendations of current guidelines on secondary prevention strategies.

Purpose

This study aimed to describe patients with CAD and eligible to secondary prevention and assess their 1-year healthcare resource consumption and costs, from the perspective of the Italian National Health Service (INHS).

Methods

From our database of Italian healthcare administrative data, reliably representative of the whole Italian population, a cross-linkage of demographics, hospital discharges and exemption code for disease cost sharing, through a unique anonymized identifying code, was performed. Patients aged ≥35 in 2018 (accrual period) with CAD (index date) and eligible to secondary prevention (by excluding subjects with end-stage kidney disease/neoplasia) were selected. They were characterized in terms of age, gender and comorbidities (from index date back to 2015) and followed for 1 year to assess drug consumption, hospitalizations and healthcare integrated costs.

Results

Out of &gt;5 million inhabitants in the database in 2018, 46,063 patients aged ≥35 (1.3%) with CAD and eligible for secondary prevention were selected (72.1% males; mean age [±SD] 70±12). About half of them had 3 or more comorbidities of interest: mostly hypertension (90%), dyslipidaemia (72%) and diabetes (33%). During 1-year follow-up, at least one drug for secondary prevention was supplied to 96.4% of patients: mainly antiplatelets (83%), lipid lowering agents (83%) and β-blockers (73%). At the same time, 95.8% of the cohort was treated with at least one non-cardiovascular drug. The 30.6% of subjects were hospitalized at least once: 11.4% due to relevant cardiovascular causes (mostly acute coronary syndrome and heart failure), 9.1% due to other cardiovascular events and 17.5% because of non-cardiovascular events. On average, the INHS yearly paid €6,078 per patient: hospitalizations accounted for the 70% of the whole expenditure.

Conclusions

This study showed an integrated view of the relevant burden of CAD for patients and the INHS. A multidisciplinary and a more adherent approach to current guidelines are compelling to improve patients’ outcomes and reduce costs for the INHS.

[Uremic pruritus through healthcare administrative data]

Background: This retrospective observational study aimed at describing patients on hemodialysis with/without uremic pruritus (UP), their healthcare resource consumption and costs from the perspective of the Italian National Health Service (INHS). Methods: Through the cross-linkage of the healthcare administrative data collected in the ReS (Ricerca e Salute) database from 2015 to 2017, patients undergoing in-hospital/outpatient hemodialysis (index date) for ≥2 years were selected. After the exclusion of subjects with other causes of pruritus, UP/non-UP cohorts were created based on the presence/absence of UP-related treatment supplies and characterized. Treatments, hospitalizations and costs were analyzed. Results: Of 1239 patients on hemodialysis for ≥2 years (20.2% of all hemodialysis subjects), 218 (17.6%) were affected by UP. Both cohorts were mostly males and elderly. One year before and after the index date, 58.1% and 65.1% of UP patients received UP-related treatments, of which >50% were treated with antihistamines (mostly cetirizine), 10% gabapentin and 1.4% ultraviolet light therapy. The mean annual overall cost per patient with/without UP was €37,065/€35,988. Outpatient specialist services accounted for 80% (>77% hemodialysis), hospitalizations for 10% (>60% hemodialysis). Conclusions: Though the prevalence of UP and related healthcare costs charged to the INHS were underestimated, the burden of UP was not negligible. High-efficiency dialytic therapies performed 3 to UP patients seemed to largely weigh on the overall mean annual cost. The availability of specific and effective treatments for UP might offer cost and healthcare offsets.

Treatment outcome of atypical EGFR mutations in the German National Network Genomic Medicine Lung Cancer (nNGM)

BACKGROUND

Atypical EGFR mutations occur in 10-30% of NSCLC patients with EGFR mutations and their sensitivity to classical EGFR-tyrosine kinase inhibitors (TKI) is highly heterogeneous. Patients harboring one group of uncommon, recurrent EGFR mutations (G719X, S768I, L861Q) respond to EGFR-TKI. Exon 20 insertions are mostly insensitive to EGFR-TKI but display sensitivity to exon 20 inhibitors. Clinical outcome data of patients with very rare point and compound mutations upon systemic treatments are still sparse to date.

PATIENTS AND METHODS

In this retrospective, multi-center study of the national Network Genomic Medicine (nNGM) in Germany, 856 NSCLC cases with atypical EGFR mutations including co-occuring mutations were reported from 12 centers. Clinical follow-up data after treatment with different EGFR-TKI, chemotherapy and immune checkpoint inhibitors were available from 260 patients. Response to treatment was analyzed in three major groups: (1) uncommon mutations (G719X, S7681, L861Q and combinations), (2) exon 20 insertions and (3) very rare EGFR mutations (very rare single point mutations, compound mutations, exon 18 deletions, exon 19 insertions).

RESULTS

Our study comprises the largest thus far reported real-world cohort of very rare EGFR single point and compound mutations treated with different systemic treatments. We validated higher efficacy of EGFR-TKI in comparison to chemotherapy in group 1 (uncommon), while most exon 20 insertions (group 2) were not EGFR-TKI responsive. In addition, we found TKI sensitivity of very rare point mutations (group 3) and of complex EGFR mutations containing exon 19 deletions or L858R mutations independent of the combination partner. Notably, treatment responses in group 3 (very rare) were highly heterogeneous. Co-occurring TP53 mutations exerted a non-significant trend for a detrimental effect on outcome in EGFR-TKI treated patients in groups 2 and 3 but not in group 1.

CONCLUSIONS

Based on our findings we propose a novel nNGM classification of uncommon EGFR mutations.

[Update on collaborative autopsy-based research in German pathology, neuropathology, and forensic medicine]

BACKGROUND

Autopsies are a valuable tool for understanding disease, including COVID-19.

MATERIALS AND METHODS

The German Registry of COVID-19 Autopsies (DeRegCOVID), established in April 2020, serves as the electronic backbone of the National Autopsy Network (NATON), launched in early 2022 following DEFEAT PANDEMIcs.

RESULTS

The NATON consortium's interconnected, collaborative autopsy research is enabled by an unprecedented collaboration of 138 individuals at more than 35 German university and non-university autopsy centers through which pathology, neuropathology, and forensic medicine autopsy data including data on biomaterials are collected in DeRegCOVID and tissue-based research and methods development are conducted. More than 145 publications have now emerged from participating autopsy centers, highlighting various basic science and clinical aspects of COVID-19, such as thromboembolic events, organ tropism, SARS-CoV‑2 detection methods, and infectivity of SARS-CoV-2 at autopsy.

CONCLUSIONS

Participating centers have demonstrated the high value of autopsy and autopsy-derived data and biomaterials to modern medicine. The planned long-term continuation and further development of the registry and network, as well as the open and participatory design, will allow the involvement of all interested partners.

[Catheter ablation in hospitalized patients diagnosed with atrial fibrillation: real-world evidence from Italian health administrative databases.]

BACKGROUND

Catheter ablation (CA) is recommended for treating paroxysmal/persistent atrial fibrillation (AF) as an alternative to antiarrhythmic drugs after failure or intolerance, or as first-line in limited cases. This study has described patients affected by AF and treated or not with CA, from the perspective of the Italian National Healthcare System (INHS).

METHODS

From the healthcare administrative data collected in the ReS (Ricerca e Salute) database, from 2016 to 2017, patients with main/secondary diagnosis of AF (index date) were split into two cohorts by presence/absence of CA procedure in the same hospital discharge form. The cohorts were characterized by gender, age, comorbidities. Consumptions (DDD) of antiarrhythmic, anticoagulant, antiplatelet and antihypertensive drugs, hospitalizations for AF, hemorrhagic stroke/intracranial hemorrhage, ischemic stroke/transient ischemic attack, extra cranial major bleeding and heart failure, outpatient specialist care and healthcare costs paid by the INHS were assessed.

RESULTS

Out of >5 million inhabitants in 2016-2017, 33,940 patients were hospitalized with a diagnosis of AF, 990 (2.9%) were treated with CA in the same hospitalization (32,950 without CA). Patients with CA were mostly males (66.8%; 48.5% without CA). On average, they were aged (±SD) 65±12 (78±11 without CA) and affected by one comorbidity (≥3 in patients without CA). During the observational period, beta-blockers were the most prescribed to both cohorts, followed by antiarrhythmic drugs to patients with CA and by direct oral anticoagulants to those without. The 29.7% of subjects with CA were hospitalized due to relevant cardiovascular diagnoses during the previous year (7.4% without CA) and 93.4% in the first follow-up year (29.7% without CA). The 80-90% of cohorts resorted to the outpatient specialist care. Electrocardiograms and the cardiology visits were performed to the 62.5% and 31.1% of the cohort with CA (39.5% and 13% without CA) in the first follow-up year. On average, the INHS spent about € 4000 in the previous year and around € 10,000 in the first follow-up year per patient of both cohorts, while around € 3000 and € 4000 for a patient respectively with and without CA. At least half of the total costs were due to hospitalizations, followed by pharmaceuticals and outpatient specialist care.

CONCLUSIONS

This study confirm a post-CA suboptimal monitoring.

MRI grading for the prediction of prostate cancer aggressiveness

OBJECTIVES

T o evaluate the value of multiparametric MRI (mpMRI) for the prediction of prostate cancer (PCA) aggressiveness.

METHODS

In this single center cohort study, consecutive patients with histologically confirmed PCA were retrospectively enrolled. Four different ISUP grade groups (1, 2, 3, 4-5) were defined and fifty patients per group were included. Several clinical (age, PSA, PSAD, percentage of PCA infiltration) and mpMRI parameters (ADC value, signal increase on high b-value images, diameter, extraprostatic extension [EPE], cross-zonal growth) were evaluated and correlated within the four groups. Based on combined descriptors, MRI grading groups (mG1-mG3) were defined to predict PCA aggressiveness.

RESULTS

In total, 200 patients (mean age 68 years, median PSA value 8.1 ng/ml) were analyzed. Between the four groups, statistically significant differences could be shown for age, PSA, PSAD, and for MRI parameters cross-zonal growth, high b-value signal increase, EPE, and ADC (p < 0.01). All examined parameters revealed a significant correlation with the histopathologic biopsy ISUP grade groups (p < 0.01), except PCA diameter (p = 0.09). A mixed linear model demonstrated the strongest prediction of the respective ISUP grade group for the MRI grading system (p < 0.01) compared to single parameters.

CONCLUSIONS

MpMRI yields relevant pre-biopsy information about PCA aggressiveness. A combination of quantitative and qualitative parameters (MRI grading groups) provided the best prediction of the biopsy ISUP grade group and may improve clinical pathway and treatment planning, adding useful information beyond PI-RADS assessment category. Due to the high prevalence of higher grade PCA in patients within mG3, an early re-biopsy seems indicated in cases of negative or post-biopsy low-grade PCA.

KEY POINTS

• MpMRI yields relevant pre-biopsy information about prostate cancer aggressiveness. • MRI grading in addition to PI-RADS classification seems to be helpful for a size independent early prediction of clinically significant PCA. • MRI grading groups may help urologists in clinical pathway and treatment planning, especially when to consider an early re-biopsy.

[Second-generation antipsychotics and cardio-metabolic events: real-world analysis and healthcare costs]

OBJECTIVE

This analysis has identified and characterized new users of second-generation antipsychotics (SGA) in Italy and has assessed the occurrence of cardio-metabolic (CM) events over 3 years after the SGA starting therapy and the annual healthcare costs, in the perspective of the Italian National Health System (INHS).

METHODS

Starting from the Fondazione ReS (Ricerca e Salute)'s database, adults treated with SGA in 2015 (index supply) were selected. By analyzing 2 previous years, treatment incidence and presence/absence of CM diseases or predisposing conditions (PC) to these events were defined and 3 cohorts were identified: A) with CM or predisposing conditions, B) only with PC, C) without neither CM nor predisposing conditions. Cohorts B and C were paired with patients with the same clinical profiles but without any SGA supply. Into cohorts and related paired groups, CM diseases/predisposing conditions occurred (cases) during the 3-year follow-up after the index supply were searched. Cases were compared with related control groups in terms of probability of CM disease/predisposing conditions occurrence (survival analysis to the event - Kaplan-Meier curves).

RESULTS

Among more than 4 million adults, 12,218 were incident to SGA (2.8 x1,000): 2,732 composed cohort A (22.5%) with median age 80 (69;87), 1,492 cohort B (12.3%) with median age 77 (63;85), 7,904 cohort C (65.2%) with median age 60 (37;84). They were mostly females. The treatment incidence increased with age. The probabilities of CM events were: 15.8% and 13.3% among cases and controls of cohort B, and 7.5% and 5.1% among cases and controls of cohort C. Probabilities of predisposing conditions occurrence were 10% and 7.0% among cases and controls of cohort C. All differences were significant (p<0.01). The mean integrated healthcare cost was similar between case and control. Hospitalizations accounted for the most expenditure.

DISCUSSION AND CONCLUSION

CM events or predisposing conditions occurrence in the elderly is both a clinical and an economic issue for the INHS. The proper therapeutic choice and monitoring of patient treated with antipsychotics must be encouraged.

[Chronic use of the unfixed combination of ACE-inhibitors and beta-blockers in Italy from 2013 to 2019 through the healthcare administrative data.]

INTRODUCTION

The association between an ACE-inhibitor and a beta-blocker is recommended in case of complicated arterial hypertension and heart failure with reduced ejection fraction. This retrospective drug-utilization study has described its chronic use from the Italian National Healthcare Service perspective.

METHODS

From the ReS (Ricerca e Salute) database, collecting Italian healthcare administrative data, patients receiving an ACE-inhibitor or a beta-blocker from 2013 to 2019 were selected. The prevalence of use (patients treated/1000 inhabitants) and of continuous treatment (patients treated for ≥80% period from the supply to the end of the same year - by means of dosage units - per 1000 inhabitants) of each single active substance were assessed. Among patients continuously treated, those supplied with an ACE-inhibitor and a beta-blocker (unfixed and fixed combinations) were analyzed in terms of prevalence of continuous treatment. Subjects treated with the unfixed combination ramipril-bisoprolol in 2019 were characterized by gender and age.

RESULTS

The prevalence of ACE-inhibitors' use increased from 49.7/1000 inhab. in 2013 to 50.2 in 2019: ramipril was the most supplied each year (28.9 to 31.6/1000 inhab.). The prevalence of continuous treatment increased from 27.4 to 28.3/1000 inhab.: ramipril the most continuously dispensed (16 to 18/1000 inhab.). The prevalence of beta-blockers' use increased from 61.0 to 90.4/1000 inhab.: bisoprolol the most supplied and with the highest increase (27.1 to 52.2/1000 inhab.). The prevalence of continuous treatment increased from 33.1 to 55.8/1000 inhab.: bisoprolol the most continuously dispensed (18 to 37/1000 inhab.). Among patients with continuous supplies, from 49,843 a 51,496 were treated with associations between an ACE-inhibitor and a beta-blocker on an ongoing basis. Half of them were continuously treated with the unfixed combination ramipril-bisoprolol (4.3 to 4.8/1000 inhab.). In 2019, subjects with continuous supplies of ramipril-bisoprolol were mainly males (63.4%) and elderly (mean age 71±12), and the prevalence of use increased with age.

CONCLUSIONS

These findings, together with recommendations from the main international guidelines encourage to make available also ramipril and bisoprolol as fixed dose combination, in order to simplify the therapy administration and improve the adherence, especially among elderly and patients with multimorbidity.

Clinical epidemiology and costs of type 2 diabetic patients with or without prior coronary artery disease or stroke. A longitudinal 5-year claims-data analysis of over 7 million inhabitants

Aims

Contemporary, real-world data on type 2 diabetes mellitus (T2DM) are limited. We analysed prevalence, comorbidities, outcomes and costs of T2DM patients with and without coronary artery disease (CAD) or stroke in &gt;7 million inhabitants.

Methods

T2DM patients were identified in 2015 (accrual period) from the Ricerca e Salute (ReS) database linking administrative records to demographics. From 2013–2015 information, four cohorts were considered: #1 with CAD and/or stroke; #2 without CAD and/or stroke; #3 with chronic CAD but no myocardial infarction or stroke; #4 with chronic CAD undergoing percutaneous coronary interventions (PCI). Hospitalizations, drugs and other outpatient care were assessed from 2015 to 2017.

Results

Prevalence of T2DM was 6% (441,085/7,365,954). CAD and/or stroke in the previous 3 years affected 7.5% of T2DM patients (33,153); this cohort was generally older, of male sex, with more comorbidities, prescriptions, and hospital admissions (50% versus 13.4%) compared to cohort #2. Yearly costs were &gt;3-fold for cohort #1 versus #2, main drivers being hospitalizations in the former and drugs in the latter. Unexpectedly, two-year cardiovascular events were significantly higher in cohort #4 compared to any other (Figure). Guideline-recommended therapies were suboptimal in all cohorts.

Conclusions

The present analysis points to three areas of potential improvement in T2DM management: 1) undertreatment of T2DM patients with recommended drugs; 2) three-fold recurrences and costs in T2DM patients with, compared to those without, prior cardiovascular events; 3) highest risk of events in those with chronic CAD and PCI, warranting specific studies aimed at defining more effective preventive strategies.

Renal function and cardiac adrenergic impairment in patients affected by heart failure

Although in heart failure (HF) there is a strict correlation between heart and kidney, no data are available on the potential relationship in HF between renal dysfunction (RD) and the impaired sympathetic innervation. Aim of the present study was to assess the relationship between RD and cardiac sympathetic innervation in HF patients with reduced ejection fraction. Two hundred and sixty-three patients with mild-to-severe HF underwent iodine-123 meta-iodobenzylguanidine myocardial scintigraphy to assess sympathetic innervation, evaluating early and late heart-to-mediastinum (H/M) ratios and washout rate. In all patients, glomerular filtration rate (eGFR) by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula was assessed. A direct association was found between EPI-eGFR and late H/M (r = .215; P < .001). Dividing the population into moderate-to-severe eGFR reduction and normal-to-mildly reduced eGFR (cutoff ≤ 60 mL·min-1·1.73 m-2), a statistically significant reduction of late H/M value was found in patients with RD compared to patients with preserved eGFR (P = .030). By multivariable linear regression analysis, eGFR resulted in the prediction of impaired late H/M in patients with RD (P = .005). Patients with RD and HF show more impaired cardiac sympathetic activity than HF patients with preserved renal function, and reduced eGFR is a predictor of reduced late H/M.

Magnetic resonance imaging improves the prediction of tumor staging in localized prostate cancer

OBJECTIVES

The aim of this study was to investigate 3 Tesla multiparametric magnetic resonance imaging (mpMRI)-based predictors for the pretherapeutic T staging of prostate cancer and their accuracy.

METHODS

Consecutive patients with 3 Tesla mpMRI, positive systematic and MR-targeted biopsy, and subsequent radical prostatectomy (RPE) between 01/2016 and 12/2017 were included. MRI parameters such as measurable extraprostatic extension (EPE) (≥ 3 mm), length of (pseudo)capsular contact (LCC), invasion of neurovascular bundle (NVBI), and/or seminal vesicles lesion contact (SVC) or infiltration (SVI) were assessed and correlated to clinical and histopathological results.

RESULTS

136 men were included. In 76 cases, a pT2 stage was determined, in 29 cases a pT3a, and in 31 a pT3b stage. The positive and negative predictive values (PPV, NPV) for the detection of T3 by measurable EPE on MRI was 98% (CI 0.88-1) and 81% (CI 0.72-0.87). No visible NVBI was found in pT2 patients (NPV 100%; CI 0.95-1). ROC analysis for T3a prediction with LCC (AUC 0.81) showed a sensitivity of 87% and a specificity of 62% at a threshold of 12.5 mm (J = 0.485) and 93% and 58% at 11 mm (Jmax = 0.512). All patients with pT3a had a LCC > 5 mm. In case of pT3b, 29/31 patients showed a SVC (PPV 76%, CI 0.61-0.87; NPV 98%, CI 0.93-0.99), and 23/31 patients showed a SVI (PPV 100%, CI 0.86-1; NPV 93%, CI 0.87-0.96). EPE (p < 0.01), LCC (p = 0.05), and SVC (p = 0.01) were independent predictors of pT3.

CONCLUSIONS

MRI-measurable EPE, LCC, and SVC were reliable, independent, preoperative predictors for a histopathological T3 stage. A LCC ≥ 11 mm indicated a pT3a stage, whereas a LCC < 5 mm excluded it. On MRI, visible SVI or even SVC of the PCa lesion was reliable preoperative predictors for a pT3b stage.

[Therapeutic drug plans: how many and which ones? Overview of a prescriptive and care appropriateness tool.]

Therapeutic plans (TPs) were introduced in Italy in 2004 in order to ensure the continuity in the prescription of new drugs between specialist physicians and general practitioners (GPs). Over the years this prescription tool was updated several times: starting from a paper form without any template ("paper TP") to a template defined by AIFA to collect specific clinical information, up to a web-based form to collect all information into a database. Over time-critical issues concerning its usefulness have been raised, especially when AIFA established several extensions for TP validity to ensure the social distancing required by the covid-19 pandemic. Therefore, after several years from their establishment, pending adoption of necessary implementing of Ministerial Decree of 25th March 2020, a check of the actual impact of TPs is required, in order to plan their review. This study provide a detailed overview of all TPs active in Italy at the 11th May 2020. From Farmadati database, all drugs reimbursed by the National Health Service (class A drugs) and requiring TP were selected. The consumption of these drugs has been derived from OsMed Reports that make available data of medicines consumption and expenditure in the general population in Italy. The analysis showed that TP is required for the prescription of 935 medicinal products (9.6% of class-A drugs) and 147 different active substances (belonging to 34 different Therapeutic Groups and 66 subgroups). Out of these, 67 (46%) required a paper TP without any template, 72 (49%) a paper TP on AIFA template, and 8 (5%) a web-based TP. The Therapeutic Group with the largest number of active ingredients with TP were antidiabetics (19.7%), followed by immunomodulating and immunosuppressants (9.5%) and medications for asthma and COPD (6.8%). Consumption analysis of drugs with TP showed that this prescription tool covers 943,899,598 DDD per year, equal to 2,586,026 DDD/day. This means that TPs have a very high impact in terms of the prevalence of patients treated on the entire care process. Of all annual DDDs prescribed on TP, 46.8% concerned drugs with TP on template AIFA, 34.5% drugs with web-based TP, while the remaining 18.7% drugs with paper TP without a template. This analysis may provide the basis for an analytical case-by-case review of TP maintenance needs, trying to maximize the benefits of this tool and to reduce its possible adverse effects. This review could be helpful to ensure the appropriateness in the drug uses, to enhance the role of general medicine, and to simplify the pathways of millions of patients ensuring the continuity of their care.

Mesopancreatic excision for pancreatic ductal adenocarcinoma improves local disease control and survival

BACKGROUND

Survival in ductal adenocarcinoma of the pancreatic head (hPDAC) is poor. After implementation of the circumferential resection margin (CRM) into standard histopathological evaluation, the margin negative resection rate has drastically dropped. However, the impact of surgical radicality on survival and the influence of malignant infiltration of the mesopancreatic fat remains unclear. At our institution, a standardized dissection of the mesopancreatic lamina and peri-pancreatic vessels are obligatory components of radical pancreatoduodenectomy. The aim of our study was to histopathologically analyze mesopancreatic tumor infiltration and the influence of CRM-evaluated resection margin on relapse-free and overall survival.

METHOD

Clinicopathological and survival parameters of 264 consecutive patients who underwent surgery for hPDAC were evaluated.

RESULTS

The rate of R0 resection R0(CRM-) was 48.5%, after the implementation of CRM. Mesopancreatic fat infiltration was evident in 78.4% of all consecutively treated patients. Patients with mesopancreatic fat infiltration were prone to lymphatic metastases (N1 and N2) and had a higher rate of positive resection margin (R1/R0(CRM+)). In multivariate analysis, only R0 resection was shown to be an independent prognostic parameter. Local recurrence was diagnosed in only 21.1% and was significantly lower in patients with R0(CRM-) resected hPDACs (10.9%, p < 0.001).

CONCLUSION

Mesopancreatic excision is justified, since mesopancreatic fat invasion was evident in the majority of our patients. It is associated with a significantly improved local tumor control as well as longer relapse-free and overall survival.

The use of β-blockers in patients with heart failure and comorbidities: Doubts, certainties and unsolved issues

β-blockers represent a mainstay in the pharmacological approach to patients affected by heart failure with reduced ejection fraction (HFrEF). However, underuse of this class of drugs is still reported, especially in the presence of cardiovascular and non-cardiovascular comorbidities, even if they are not contraindications for prescription of a β-blocker. The prognostic benefit of β-blockers is relevant in the presence of comorbidities, and achievement of the maximum tolerated dose is an important goal to increase their favorable prognostic role. The aim of the present review is to analyze the available evidence on the use of β-blockers in HFrEF patients with the most common comorbidities. In particular, we will discuss the role and most appropriate beta-blocker in patients with pulmonary disease (bisoprolol, metoprolol, nebivolol), diabetes (carvedilol and nebivolol), atrial fibrillation (all indicated for rate control, with metoprolol as the first choice followed by bisoprolol, nebivolol, and carvedilol), erectile dysfunction (bisoprolol and nebivolol), peripheral arterial disease (nebivolol), and other conditions, in order to clarify the correct use of this class of drugs in the clinical practice.

Insights into real-world treatment of cluster headache through a large Italian database: prevalence, prescription patterns, and costs

Objective: This study aimed at estimating the treated cluster headache (CH) prevalence and describing prescription patterns and direct costs paid by the Italian National-Health-System.Methods: Through the ReS database (healthcare administrative data collection of a large sample of the Italian population), adults in treatment for CH (acute therapy with sumatriptan/subcutaneous or oxygen, associated with preventive therapy with verapamil or lithium) were selected. A cross-sectional analysis described the prevalence of CH-treated subjects repeated annually in 2013-2017. A longitudinal analysis of patients selected in 2013-2015 and followed for 2 years provided the prescription patterns.Results: The annual prevalence of CH-treated patients increased from 6.4×100,000 adults in 2013 to 6.7 in 2017. In 2013-2015, 570 patients (80.7% M; mean age 46) treated for CH were found. In 50.4%, the identifying CH treatment was sumatriptan/subcutaneous+verapamil. During follow-up, >1/3 changed the preventive drug and interruption was the most frequent modification, although acute treatments were still prescribed. The mean annual cost/patient ranged from €2,956 to €2,267; pharmaceuticals expenditure represented the 56.4% and 57.3%, respectively.Conclusions: This study showed an important unmet need among CH patients, carrying a high economic burden that should be considered in the evaluation of the impact of incoming therapies (e.g. Calcitonin-Gene-Related-Peptide antibodies).

Real-world Prescription Pattern, Discontinuation and Costs of Ibrutinib-Naïve Patients with Chronic Lymphocytic Leukemia: An Italian Healthcare Administrative Database Analysis

BACKGROUND AND OBJECTIVE

In order to integrate the existing and inconsistent information from clinical trials and real-world practice on chronic lymphocytic leukemia (CLL) treated with ibrutinib, this analysis aimed to describe the prescription pattern of new users of ibrutinib affected by CLL, focusing on discontinuation, severe adverse events (AEs) and change of treatment, and to assess the integrated healthcare expenditure from the Italian National Health System (INHS) perspective.

METHODS

Starting from the ReS database, adults with at least a supply of ibrutinib (ATC code L01XE27) were selected from 01/01/2016 to 12/31/2017. Those without any ibrutinib supply in the year before the index prescription were considered new users. Out of them, only patients with at least a primary or secondary in-hospital diagnosis of CLL (ICD-9-CM code 204.1*) from 01/01/2013 to 12/31/2018 were further broken down according to the ibrutinib's line treatment (first line-FL; second or later line-SLL) and analysed. They were characterized by sex and age in the selection period. Mean annual consumption (defined daily doses [DDD]), treatment discontinuation, changes of therapy, interruptions and healthcare costs in charge of the INHS were assessed during two follow-up years.

RESULTS

Out of more than 5 million inhabitants of the ReS database, 69 new ibrutinib users and diagnosed with CLL in 2016 (incidence: 1.6 × 100,000) and 41 in 2017 (incidence: 0.9 × 100,000) were selected. Of these, 21 (19.1%) were FL ibrutinib users and 89 (80.9%) were SLL ones, mostly males and with mean ages (±SD) of 65 ± 14 and 70 ± 10, respectively. The mean annual consumption among FL users decreased from 222.2 DDD per patient treated to 216.0 DDD, while increased among SLL patients from 238.6 DDD to 260.1 DDD, in the first and second follow-up year, respectively. The discontinuation rate was about 40% in the first year, similarly among FL and SLL users. SLL patients discontinued more frequently (52.8% vs 20.0%) in the second year. Very few AEs were recorded. The 62.5% of FL and 55.6% of SLL users discontinuing ibrutinib in 1-year follow-up, while one SLL patient (5.3%) in the second year changed therapy. The 20.0% and 15.9% of all new users in first and second year interrupted ibrutinib. The total integrated cost of FL patients was €55,732 reducing by about €15,000, while it was €58,716 for SLL ones decreasing by €6,000, respectively, in the first and in the second year. Pharmaceuticals were the key cost driver (ibrutinib accounted for more than 77%).

CONCLUSIONS

This analysis on Italian administrative data provided results about prescription patterns of ibrutinib FL and SLL new users with CLL, focusing on discontinuation, treatment change and healthcare costs over 2-year follow-up, and contributed to improve the knowledge on this hard-to-treat disease.

Reasons for missing clinically significant prostate cancer by targeted magnetic resonance imaging/ultrasound fusion-guided biopsy

OBJECTIVES

This study evaluates cases with clinically significant prostate cancer (csPCa) missed by targeted biopsy (TB) and analyzes the diagnostic impact of an additional systematic biopsy (SB) in a large patient collective.

METHODS

Consecutive patients with a 3 T multiparametric prostate MRI (mpMRI) and a subsequent MRI/US fusion-guided TB plus 12-core US-guided SB from 01/2014 to 04/2019 were included in this study. Primary study endpoint was the analysis of cases with a csPCa missed by TB and detected by SB. Secondary study objectives were the PCa detection and the correlation with clinical and MRI parameters.

RESULTS

In total 785 patients met the inclusion criteria. 342 patients had a csPCa (median PSAD 0.29 ng/mL/cm³). In 42 patients (13 %), a csPCa was detected only by SB. In 36 of these cases, the localization of the positive SB cores matched with the cancer suspicious region described on mpMRI (mCSR). Cases with a csPCA missed by TB showed either an insufficient MRI segmentation (prostate boundary correlation) (31 %) and/or insufficient lesion registration (lesion transfer, tracking, and/or matching) (48 %), a missed small lesion (14 %), or a failed center of a large lesion (10 %). Median PSAD of patients with non-significant PCa detected by SB was 0.15 ng/mL/cm³.

CONCLUSIONS

Main reasons for missing a csPCa by TB were insufficient prostate segmentation or imprecise lesion registration within MRI/US fusion-guided biopsy. Consequently, verification of MRI quality, exact mCSR assessment, and advanced biopsy experience may improve accuracy. Altogether, an additional SB adds limited clinical benefit in men with PSAD ≤ 0.15 ng/mL/cm³.

Effects of glucagon-like peptide-1 receptor agonists on major cardiovascular events in patients with Type 2 diabetes mellitus with or without established cardiovascular disease: a meta-analysis of randomized controlled trials

Aims 

Glucose-lowering, glucagon-like peptide-1 (GLP-1) receptor agonists reduce incidence of major cardiovascular (CV) events in patients with Type 2 diabetes mellitus (DM). However, randomized clinical trials reported inconsistent effects on myocardial infarction (MI) and stroke, and limited data in DM patients without established CV disease (CVD). Very recently, new relevant evidence was available from additional CV outcome trials (CVOTs) that also included large subgroups of patients with DM without established CVD. Thus, the aim of this meta-analysis was to investigate the effects of GLP-1 receptor agonists on major CV events and safety in DM patients with and without established CVD.

Methods and results 

In this trial-level meta-analysis, we analysed data from randomized placebo-controlled CVOTs assessing efficacy and safety of GLP-1 receptor agonists in adult patients with Type 2 DM. We searched PubMed, Embase, Cochrane, ISI Web of Science, SCOPUS, and clinicaltrial.gov databases for eligible trials. Of 360 articles identified and screened for eligibility, seven CVOTs were included, with an overall of 56 004 patients included. The difference in efficacy with respect to the major adverse cardiovascular events (MACE) primary endpoint (including CV mortality, non-fatal MI, and non-fatal stroke) between patients with established CVD and patients with CV risk factors only was not significant [pooled interaction effect, expressed as ratio of hazard ratio (HR) 1.06, 95% confidence interval (CI) 0.85–1.34]. In the analysis of the whole population of DM patients, GLP-1 receptor agonists showed a significant 12% reduction in the hazard of the three-point MACE composite endpoint (HR 0.88, 95% CI 0.80–0.96) and a significant reduction in the risk of CV mortality (HR 0.88, 95% CI 0.79–0.98), all-cause mortality (HR 0.89, 95% CI 0.81–0.97), fatal and non-fatal stroke (HR 0.84, 95% CI 0.76–0.94), and heart failure (HF) hospitalization (HR 0.92, 95% CI 0.86–0.97). No significant effect was observed for fatal and non-fatal MI (HR 0.91, 95% CI 0.82–1.02), although in a sensitivity analysis, based on a less conservative statistical approach, the pooled HR become statistically significant (HR 0.91, 95% CI 0.83–1.00; P = 0.039). No excess of hypoglycaemia, pancreatitis, and pancreatic cancer was observed between GLP-1 receptor agonists and placebo.

Conclusion 

Glucagon-like peptide-1 receptor agonists significantly reduce MACE, CV and total mortality stroke, and hospitalization for HF, with a trend for reduction of MI, in patients with Type 2 DM with and without established CVD.

[Facts and figures of clinical pathways in Italy: results from the PDTA Net project.]

The approval of clinical pathways (CPWs) represents a key step to focus the care management on the patient. The PDTA Net project, by ReS Foundation and CINECA, aims to create a reference tool to study how the local organizational models influence healthcare and clinical outcomes. The article shows the analysis of all CPWs approved by Italian Regions and Autonomous Provinces until 31/12/2018. The search for documents was performed on the institutional websites through specific keywords. CPWs were filled into a database, according to the Region, publication year, disease of interest (distinguishing between chronic diseases with high epidemiological impact and rare diseases) and relevant clinical area. All documents were analyzed by geographical and temporal distribution, the latter also according to ministerial measures. From 2005 to 2018, 536 Regional CPWs were approved (316 for chronic diseases with a high epidemiological impact and 220 for rare diseases). The Regions with the highest number of CPWs of chronic diseases were Umbria (34 CPWs) and Piemonte (33). The most addressed clinical areas were: oncology (72), neurology (60), cardiology (34) and metabolic disorders (22). The most issued diseases were: diabetes (17), trauma/polytrauma (15), chronic obstructive pulmonary disease and multiple sclerosis (12 each), stroke (11), rheumatoid arthritis, breast cancer and colorectal neoplasms (10 each). The publication of the documents was affected by ministerial measures (Balduzzi Law, National Chronicity Plan, Diabetic Disease Plan and National Dementia Plan). The majority of CPWs on rare diseases was retrieved in Regions with activated Rare Disease Networks: Lombardia (110 CPWs), Lazio (64) and Toscana (17). This study showed that, to date, in Italy there are several CPWs published at Regional level, nevertheless their structure and application are heterogeneous and strongly influenced by the National Plans. All analyzed documents are available through the web platform of the project https://fondazioneres.it/pdta/. This project could be useful for health system stakeholders, in order to encourage the transition to new health governance and making CPWs effective governance tools.

Anticancer drug prices and clinical outcomes: a cross-sectional study in Italy

OBJECTIVE

To investigate whether the prices of new anticancer drugs correlated with their relative benefit despite negotiation.

DESIGN

Retrospective cross-sectional study correlating new anticancer drugs prices with clinical outcomes.

SETTING

We did a retrospective cross-sectional study including all new anticancer drugs approved by the European Medicines Agency (EMA) (2010-2016) and reimbursed in Italy.

MAIN OUTCOMES AND MEASURES

Information on clinical outcomes-in terms of median overall survival (OS), median progression-free survival (PFS) and objective response rate (ORR)-was extracted from pivotal trials as reported in the European Public Assessment Reports available on the EMA website. Cost of a full course treatment was estimated on negotiated official and discounted prices. Regression coefficients β, their levels of significance p and the coefficients of determination R2 were estimated adjusting by tumour type.

RESULTS

Overall, 30 new anticancer drugs (with 35 indications) were available for analysis. Where data on OS were available, we observed no correlation between the improvement in median OS (in weeks) and negotiated price (R2=0.067, n=16 drugs for 17 indications). When the clinical outcomes were expressed as improvements in the median PFS or ORR, 25 drugs (29 indications) were available for the analysis, and again, there was no correlation with prices (R2=0.004 and 0.006, respectively).

CONCLUSIONS AND RELEVANCE

Our results suggest that the prices of anticancer drugs in Italy do not reflect their therapeutic benefit. Drug price negotiations, which is mandatory by law in Italy, do not seem to ensure that prices correlate with clinical benefits provided by the cancer drugs. These results call for further efforts to establish the standard determinants of drug prices available at the time of negotiation. These findings need to be confirmed in other countries where price negotiations are in place. Moreover, further investigations may verify whether outcome data obtained after drug marketing would improve the correlation between prices and therapeutic benefit.
