Acute treatment of migraine: quantifying the unmet need through real-world data in Italy.

OBJECTIVE: This study is describing subjects with migraine interrupting or not receiving triptans for acute treatment and providing a national-level estimate of people who might benefit from different therapeutic approaches. METHODS: This is a retrospective analysis using IQVIA Longitudinal Patient Database. Starting from 18 + years old individuals with migraine, we selected two cohorts: subjects with triptans prescriptions before and no triptans prescriptions after Index Date (triptan withdraw) and subjects without triptans prescriptions both before and after Index Date (no triptan prescriptions). Index Date was the first record of a health encounter for migraine in 2019. Individuals with cardiovascular disease (CVD) within no triptan prescriptions group were also quantified. RESULTS: Triptan withdraw and no triptan prescriptions cohorts numbered 605 and 3270, respectively, 5% and 29% of subjects with migraine. Mean age was 47 and 51 years respectively; women were more represented (~ 80%). Hypertension and thyroid disease were most frequent comorbidities; non-steroidal anti-inflammatory drugs were among most frequently recorded treatments. Subjects with CVD within no triptan prescriptions cohort were 621 and with triptan withdraw cohort subjects represented the basis to estimate those who might benefit from alternative options for the acute treatment of migraine, who were around 60,000 and accounted for 11% of subjects seeking primary care due to migraine. CONCLUSIONS: This analysis provides a real-word estimate of Italian people that might benefit from different therapeutic approaches as an alternative to triptans, which sometimes might be not effective and/or poorly tolerated. Such estimate should be intended as the lower limit of a wider range due to strict criteria adopted.

Cost-effectiveness analysis of gemtuzumab ozogamicin for the treatment of de novo CD33-positive Acute Myeloid Leukaemia (AML) in Italy.

BACKGROUND: Based on the results from the ALFA-0701 study, gemtuzumab ozogamicin (GO) has been approved by the European Medicine Agency and by the Italian Drug Agency for the first line treatment of de novo acute-myeloid leukemia (AML). In this analysis, we assessed the cost-effectiveness of GO in combination with daunorubicin and cytarabine (DA), vs DA alone, adopting the perspective of the Italian National Health Service. METHODS: For this analysis, a cohort state transition model was developed. The model was designed to capture health states and events that occur throughout the entire disease course and that impact costs and outcomes. The ALFA-0701 study was the main source of clinical data for this analysis. In the model, patients had the same baseline characteristics and experienced the same clinical improvements as in the ALFA-0701 study. Economic data (resource consumption and unit costs) were adapted to reflect expenditure for the Italian National Health Service. Utilities per health state and disutilities due to adverse events were based on the literature and on the general population for those functionally cured. A lifetime horizon was adopted, with both costs and outcome being discounted of 3.0%, annually. Deterministic and probabilistic sensitivity analyses were conducted to assess the robustness of results. RESULTS: In the base case (lifetime horizon; primary source of data: study ALFA-0701; perspective: Italian National Health Service; discount rate on costs and outcomes: 3.0%), GO + DA was more effective DA both in terms of life-year (LY) survival (6.42 LY vs 5.75 LY, respectively) and quality-of-life adjusted survival (4.69 QALY vs 4.19 QALY, respectively). The overall costs were almost similar in the two groups (slightly lower with GO + DA than with DA; €162,424 and €162,708, respectively). The use of GO increased the costs of drug therapy but saved costs of relapse and costs associated with transplantation (HSCT). CONCLUSIONS: If results of the ALFA-0701 study are applied to the Italian healthcare environment, then gemtuzumab ozogamicin, in combination with daunorubicin and cytarabine, would clinical outcomes and reduce lifetime costs, compared with daunorubicin and cytarabine alone for the first line treatment of de novo AML. TRIAL REGISTRATION: Not applicable.

Gene therapy for Duchenne Muscular Dystrophy: assessing the readiness of Italian centres of expertise.

Objectives: Duchenne muscular dystrophy (DMD) is a heritable disorder that causes a rapid and progressive loss of ambulatory skills. There is no curative therapy for this pathology, that is currently managed with a combination of physiotherapy and pharmacological interventions limiting the progression of the disease (e.g. corticosteroids, cardiac medications). However, a new opportunity is represented by gene therapy, a promising treatment that, however, requires significant expertise during the whole delivery of care and a solid organisational infrastructure. An organisational strategy that could effectively support its delivery to DMD patients in Italy is the hub-and-spoke model. However, an accurate portrait of the present network of DMD centres of expertise in Italy and of their readiness in the delivery of gene therapy is paramount, to facilitate access to this experimental medicine in the future. Methods: In this context, the present study aimed to map the DMD centres of expertise in Italy and later evaluate their preparedness in terms of gene therapy delivery. For this purpose, a series of items was proposed to 30 centres in Italy, of which 20 responded. Results: After assessing the readiness of the involved centres in terms of patient preparation, therapy infusion, close surveillance, and long-term follow-up, we proposed a suitable organizational model, namely a flexible hub-and-spoke model, for the delivery of gene therapy in the Italian DMD network and solutions to tackle the challenges emerged from the survey. Conclusion: Overall, the present study detected an adequate readiness of the Italian DMD centres of expertise, despite observing a significant room for improvement in digital infrastructures, culture, and training.

Cost-Effectiveness of Vaccination with the 20-Valent Pneumococcal Conjugate Vaccine in the Italian Adult Population.

The availability of a new 20-valent pneumococcal conjugate vaccine (PCV) makes it appropriate to assess its cost-effectiveness. This was evaluated by adopting the Italian National Health Service perspective, using a cost consequences Markovian model. The expected effects of vaccination with 20-valent PCV were compared with the administration of 13-valent PCV and 15-valent PCV. Assuming a 100% vaccination of cohorts aged 65-74 years, in the (lifetime) comparison between 20-valent PCV and 13-valent PCV, the former is dominant (lower cost for a better health outcome). A reduction in disease events was estimated: -1208 deaths; -1171 cases of bacteraemia; -227 of meningitis; -9845 hospitalised all-cause nonbacteremic pneumonia cases (NBP) and -21,058 non-hospitalised. Overall, in the Italian population, a total gain of 6581.6 life years and of 4734.0 QALY was estimated. On the cost side, against an increase in vaccinations costs (EUR +40.568 million), other direct health costs are reduced by EUR 48.032 million, with a net saving of EUR +7.464 million. The comparison between 20-valent PCV and 15-valent PCV results in an Incremental Cost-Effectiveness Ratio (ICER) of EUR 66 per life year gained and EUR 91 per QALY gained. The sensitivity analyses confirm the robustness of the results. We can conclude that the switch to 20-valent PCV is a sustainable and efficient investment.

Pediatric growth hormone treatment in Italy: A systematic review of epidemiology, quality of life, treatment adherence, and economic impact.

OBJECTIVES: This systematic review aims to describe 1) the epidemiology of the diseases indicated for treatment with growth hormone (GH) in Italy; 2) the adherence to the GH treatment in Italy and factors associated with non-adherence; 3) the economic impact of GH treatment in Italy; 4) the quality of life of patients treated with GH and their caregivers in Italy. METHODS: Systematic literature searches were performed in PubMed, Embase and Web of Science from January 2010 to March 2021. Literature selection process, data extraction and quality assessment were performed by two independent reviewers. Study protocol has been registered in PROSPERO (CRD42021240455). RESULTS: We included 25 studies in the qualitative synthesis. The estimated prevalence of growth hormone deficiency (GHD) was 1/4,000-10,000 in the general population of children; the prevalence of Short Stature HOmeoboX Containing gene deficiency (SHOX-D) was 1/1,000-2,000 in the general population of children; the birth prevalence of Turner syndrome was 1/2,500; the birth prevalence of Prader-Willi syndrome (PWS) was 1/15,000. Treatment adherence was suboptimal, with a range of non-adherent patients of 10-30%. The main reasons for suboptimal adherence were forgetfulness, being away from home, pain/discomfort caused by the injection. Economic studies reported a total cost for a complete multi-year course of GH treatment of almost 100,000 euros. A study showed that drug wastage can amount up to 15% of consumption, and that in some Italian regions there could be a considerable over- or under-prescribing. In general, patients and caregivers considered the GH treatment acceptable. There was a general satisfaction among patients with regard to social and school life and GH treatment outcomes, while there was a certain level of intolerance to GH treatment among adolescents. Studies on PWS patients and their caregivers showed a lower quality of life compared to the general population, and that social stigma persists. CONCLUSION: Growth failure conditions with approved GH treatment in Italy constitute a significant burden of disease in clinical, social, and economic terms. GH treatment is generally considered acceptable by patients and caregivers. The total cost of the GH treatment is considerable; there are margins for improving efficiency, by increasing adherence, reducing drug wastage and promoting prescriptive appropriateness.

Cost-effectiveness Comparison of Ceftazidime/Avibactam Versus Meropenem in the Empirical Treatment of Hospital-acquired Pneumonia, Including Ventilator-associated Pneumonia, in Italy.

PURPOSE: Ceftazidime/avibactam (CAZ-AVI) is a fixed-dose combination antibiotic approved in Europe and the United States for patients with hospital-acquired pneumonia, including ventilator-associated pneumonia (HAP/VAP). The economic benefits of a new drug such as CAZ-AVI are required to be assessed against those of available comparators, from the perspective of health care providers and payers, through cost-effectiveness and cost-utility analyses. The objective of this analysis was to compare the cost-effectiveness of CAZ-AVI versus meropenem in the empirical treatment of appropriate hospitalized patients with HAP/VAP caused by gram-negative pathogens, from the perspective of publicly funded health care in Italy (third-party perspective, based on the data from the REPROVE (Ceftazidime-Avibactam Versus Meropenem In Nosocomial Pneumonia, Including Ventilator-Associated Pneumonia) clinical study; ClinicalTrials.gov NCT01808092). METHODS: A patient-level, sequential simulation model of the HAP/VAP clinical course was developed using spreadsheet software. The analysis focused on direct medical costs. The time horizon of the model selected was 5 years, with an annual discount rate of 3% on costs and quality-adjusted life-years (QALYs). Clinical inputs for treatment comparisons were mainly obtained from the REPROVE clinical study data. In addition to clinical outcomes observed in the trial, the model incorporated impact of resistance pathogens, based on data from published studies and expert opinion. Certain assumptions were made for some model parameters due to a lack of data. FINDINGS: The analysis demonstrated that the intervention sequence (CAZ-AVI followed by colistin + high-dose meropenem) versus the comparator sequence (meropenem followed by colistin + high-dose meropenem) provided a better clinical cure rate (+13.52%), which led to a shorter hospital stay (-0.40 days per patient), and gains in the number of life-years (+0.195) and QALYs (+0.350) per patient. The intervention sequence had an estimated net incremental total cost of €1254 ($1401) per patient, and the estimated incremental cost-effectiveness ratio was €3581 ($4000) per QALY gained, well below the willingness-to-pay threshold of €30,000 ($33,507) per QALY in Italy. IMPLICATIONS: The model results showed that CAZ-AVI is expected to provide clinical benefits in hospitalized patients with HAP/VAP in Italy at an acceptable cost compared to meropenem.

Estimating the Clinical and Economic Impact of Switching from the 13-Valent Pneumococcal Conjugate Vaccine (PCV13) to the 10-Valent Pneumococcal Conjugate Vaccine (PCV10) in Italy.

Background: Invasive and non-invasive pneumococcal diseases are significant health and economic burdens, especially in children and the elderly. Italy included the 7-valent (PCV7) and 13-valent pneumococcal conjugate vaccine (PCV13) in the National Immunization Program in 2007 and 2010, respectively, allowing a dramatic reduction in the burden of pneumococcal disease. In the era of budget constraints, decision-makers may consider switching from the higher-valent, more costly PCV13, to the lower-cost PCV10. This study estimated the potential public health and economic impact of changing vaccine programs from PCV13 to PCV10 in Italy. Methods: A decision-analytic forecasting model estimated the impact of PCV programs. Real-world surveillance data were used to forecast serotype distribution and disease incidence among children and the elderly over a specified 5-year time horizon. Costs and outcomes included estimates of cases and deaths avoided, quality-adjusted life years (QALYs) gained, and total costs from a payer perspective, discounted at an assumed rate of 3.0%, and robustness validated through several scenarios and sensitivity analyses. Results: A switch from PCV13 to PCV10 would increase invasive pneumococcal disease (IPD) cases by 59.3% (4317 cases) over a 5-year horizon, primarily due to serotypes 3 and 19A. Pneumonia increased by 8.3% and acute otitis media (AOM) by 96.1%. Maintaining a PCV13 program would prevent a total incremental 531,435 disease cases (1.02M over a 10-year time horizon) and 641 deaths due to invasive pneumococcal disease (IPD), with €23,642 per QALY gained over 5 years versus PCV10. One-way and probabilistic sensitivity analyses showed that a PCV13-based program remained cost-effective in 99.7% of the simulations in Italy as parameters varied within their plausible range; percent vaccinated had the most impact. Conclusions: Maintaining the PCV13 strategy would provide substantial public health and economic benefits in Italy and is cost-effective. Switching from PCV13 to PCV10 would increase the incidence of pneumococcal disease primarily linked to re-emergence of serotypes 3 and 19A.

Cost-effectiveness analysis comparing ceftazidime/avibactam (CAZ-AVI) as empirical treatment comparing to ceftolozane/tazobactam and to meropenem for complicated intra-abdominal infection (cIAI).

Background: The rising incidence of resistance to currently available antibiotics among pathogens, particularly Gram-negative pathogens, in complicated intra-abdominal infections (cIAIs) has become a challenge for clinicians. Ceftazidime/avibactam (CAZ-AVI) is a fixed-dose antibiotic approved in Europe and the United States for treating (in combination with metronidazole) cIAI in adult hospitalised patients who have limited or no alternative treatment options. The approval was based on the results of RECLAIM, a Phase III, parallel-group, comparative study (RECLAIM 1 [NCT01499290] and RECLAIM 2 [NCT01500239]). The objective of our study was to assess the cost-effectiveness of CAZ-AVI plus metronidazole compared with 1) ceftolozane/tazobactam plus metronidazole and 2) meropenem, as an empiric treatment for the management of cIAI in Italy. Methods: A sequential, patient-level simulation model, with a 5-year time horizon and 3% annual discount rate (applied to both costs and health benefits), was developed using Microsoft Excel® to demonstrate the clinical course of the disease. The impact of resistant pathogens was included as an additional factor. Results: In the base-case analysis, the CAZ-AVI sequence (CAZ-AVI plus metronidazole followed by a colistin + tigecycline + high-dose meropenem combination after treatment failure), when compared to sequences for ceftolozane/tazobactam (ceftolozane/tazobactam plus metronidazole followed by colistin + tigecycline + high-dose meropenem after treatment failure) and meropenem (meropenem followed by colistin + tigecycline + high-dose meropenem after treatment failure), had better clinical outcomes with higher cure rates (93.04% vs. 91.52%; 92.98% vs. 90.24%, respectively), shorter hospital stays (∆ = - 0.38 and ∆ = - 1.24 days per patient, respectively), and higher quality-adjusted life years (QALYs) gained per patient (4.021 vs. 3.982; 4.019 vs. 3.960, respectively). The incremental cost effectiveness ratio in the CAZ-AVI sequence was €4099 and €15,574 per QALY gained versus each comparator sequence, respectively, well below the willingness-to-pay threshold of €30,000 per QALY accepted in Italy. Conclusions: The model results demonstrated that CAZ-AVI plus metronidazole could be a cost-effective alternative when compared with other antibiotic treatment options, as it is expected to provide better clinical benefits in hospitalised patients with cIAI in Italy.

Cost-effectiveness analysis of ceftazidime/avibactam compared to imipenem as empirical treatment for complicated urinary tract infections.

Ceftazidime/avibactam (CAZ-AVI) is a novel, fixed-dose combination antibiotic that has been approved in Europe and the United States for patients with complicated urinary tract infections (cUTIs) based on results of a Phase III, randomized, comparative study (RECAPTURE study). The present analysis evaluated cost-effectiveness of CAZ-AVI as an empirical treatment for hospitalized patients with cUTIs from the Italian publicly funded healthcare (third-party payer) perspective. A sequential, patient-level simulation model was developed that followed the clinical course of cUTI and generated 5000 pairs of identical patients (CAZ-AVI or imipenem as empirical treatment). The model included additional impact of resistant pathogens; patients who did not respond to empirical treatment were switched to second-line treatment of colistin+high dose carbapenem in both groups. The time horizon of the model was five years, with an annual discount rate of 3% applied to both costs and quality-adjusted life-years (QALYs). The analysis demonstrated that an intervention sequence (CAZ-AVI followed by colistin+high dose carbapenem) compared with a comparator sequence (imipenem followed by colistin+high dose carbapenem) was associated with a net incremental cost of €1015 per patient but provided better health outcomes in terms of clinical cure (97.65% vs. 91.08%; ∆ = 6.57%), shorter hospital stays (10.65 vs. 12.55 days; ∆ = 1.90 days), and QALYs gained per patient (4.190 vs. 4.063; ∆ = 0.126). The incremental cost-effectiveness ratio was €8039/QALY, which is well below the willingness-to-pay threshold of €30 000/QALY in Italy. The results showed that CAZ-AVI is expected to be a cost-effective treatment compared with imipenem for cUTI in Italy.

Atorvastatin Reduces Circulating Osteoprogenitor Cells and T-Cell RANKL Expression in Osteoporotic Women: Implications for the Bone-Vascular Axis.

AIM: Circulating osteoprogenitors and receptor activator of nuclear factor kappa-B ligand (RANKL) expression in immune cells have been implicated in the pathogenesis of osteoporosis and vascular calcification. The role played by statin therapy in the bone-vascular axis is unknown. METHODS: Twenty naïve postmenopausal osteoporotic hypercholesterolemic women were treated with Atorvastatin 40 mg/day for 3 months. Gene expression analysis was performed to assess modification in osteoprotegerin (OPG)/RANK/RANKL expression in isolated T cells and monocytes. A flow cytometry analysis was used to study changes in the levels of circulating osteoprogenitor cells. RESULTS: After 3 months of treatment, Atorvastatin significantly reduced total cholesterol and LDL-C, without affecting HDL-C and triglycerides. Among circulating bone and phosphocalcium homeostasis markers, we found a significant increase in OPG levels (P < 0.01) and a modest reduction in osteocalcin (OCN) (P < 0.05). We also observed a significant reduction in RANKL expression in T cells (P < 0.05). No differences were found in the expression of RANK in T cells and RANKL and RANK in monocytes. OPG expression was low in both immune cell types and was not affected by the treatment. As for circulating osteoprogenitors, we found a significant reduction of CD34(+) BAP(+) (P < 0.05) and CD34(+) OCN(+) BAP(+) (P < 0.05) cells. In vitro studies showed that Atorvastatin reduced RANKL expression in activated human T-lymphoblastoid cells (Jurkat cell line). CONCLUSIONS: Three-month Atorvastatin treatment leads to a reduction in circulating osteoprogenitor cells and RANKL expression in T cells, as well as increase in OPG serum levels. These data suggest that statins could have protective effects in the bone-vascular axis.

Depression: cost-of-illness studies in the international literature, a review.

BACKGROUND: Depression is one of the most ancient and common diseases of the human race and its burden on society is really impressive. This stems both from the epidemiological spread (lifetime prevalence rate, up to 30 years of age, was estimated as greater than 14.4% by Angst et al.) and from the economic burden on healthcare systems and society, but also as it pertains to patient well-being. AIMS OF THE STUDY: The scope of this review was to examine studies published in the international literature to describe and compare the social costs of depression in various countries. METHODS: A bibliographic search was performed on international medical literature databases (Medline, Embase), where all studies published after 1970 were selected. Studies were carefully evaluated and only those that provided cost data were included in the comparative analysis; this latter phase was conducted using a newly developed evaluation chart. RESULTS: 10 abstracts were firstly selected; 46 of them underwent a subsequent full paper reading, thus providing seven papers, which were the subject of the in-depth comparative analysis: three studies investigated the cost of depression in the USA, three studies in the UK and one study was related to Italy. All the studies examined highlight the relevant economic burden of depression; in 1990, including both direct and indirect costs, it accounted for US$ 43.7 billion in the US (US$ 65 billion, at 1998 prices) according to Greenberg and colleagues, whilst direct costs accounted for £417 million in the UK (or US$ 962.5 million, at 1998 prices), according to Kind and Sorensen. Within direct costs, the major cost driver was indeed hospitalization, which represented something in between 43 and 75% of the average per patient cost; conversely, drug cost accounted for only 2% to 11% in five out of seven studies. DISCUSSION: Indeed, our review suggests that at the direct cost level, in both the United States and the United Kingdom, the burden of depression is remarkable, and this is confirmed by a recent report issued by the Pharmaceutical Research and Manufacturers Association (PhRMA) where prevalence and cost of disease were compared for several major chronic diseases, including Alzheimer, asthma, cancer, depression, osteoporosis, hypertension, schizophrenia and others: in this comparison, depression is one of the most significant diseases, ranked third by prevalence and sixth in terms of economic burden. Moreover, in terms of the average cost per patient, depression imposes a societal burden that is larger than other chronic conditions such as hypertension, rheumatoid arthritis, asthma and osteoporosis. The application of economic methods to the epidemiological and clinical field is a relatively recent development, as evidenced by the finding that, out of the seven studies examined, three refer to the US environment, three to the UK and one to Italy, while nothing was available about the cost of depression for large countries such as France, Germany, Spain, Japan and others. IMPLICATION FOR HEALTH CARE PROVISION AND USE: The high incidence of hospitalization, and the finding that drug cost represents only a minor component of the total direct cost of the disease, suggests that room is still available for disease management strategies that, while effectively managing the patient's clinical profile, could also improve health economic efficiency. IMPLICATION FOR HEALTH POLICIES: Disease management strategies, with particular emphasis on education, should be targeted not only at patients and medical professionals but also at health decision makers in order "to encourage effective prevention and treatment of depressive illness". IMPLICATIONS FOR FURTHER RESEARCH: Cost of illness studies are a very useful tool allowing cost data comparisons across countries and diseases: for this reason, we suggest that further research is needed especially in some western European countries to assess the true economic burden of depression on societies.

[Clinical aspects of osteoporosis]. / Gli aspetti clinici dell'osteoporosi.

The main clinical presentation of osteoporosis is fracture and its consequences. However a number of diseases and factors can induce bone loss and increase the risk of fracture. Therefore the clinical approach should be initially directed to exclude secondary osteoporosis. Vertebral fractures are the most common osteoporotic fractures; they are characterized by back pain, typical physical changes such as kyphosis and height loss, functional impairment and social decline. On the other hand, hip fracture is the most severe consequence of osteoporosis, because of its higher morbility and mortality. The main pathogenetic determinants of hip fracture are represented by both bone loss and several factors contributing to fall in the elderly. Moreover, a number of conditions are responsible for the high mortality rate following hip fracture. Colles' fracture is rarely hospitalized; however, most patients complain a complex algodystrophic syndrome which impairs the quality of life.
