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: 110 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

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.

Purpose: Ceftazidime/avibactam (CAZ-AVI) is a fixed-dose combination antibiotic approved in Europe and the United States for patients with hospitalacquired 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 V1254 ($1401) per patient, and the estimated incremental cost-effectiveness ratio was V3581

The time course of the serum and urine concentrations of rifampicin were evaluated during and after administration of an intravenous preparation of the antibiotic. 300, 450 and 600 mg dose levels of the antibiotic were evaluated, all being given as intravenous infusion after solution in 500 ml of glucose, the infusion lasting 3 h. The results have shown that the serum level curves and the kinetic parameters calculated on them do not differ to any major extent from those corresponding to the same doses given orally. No changes of relevance in the half-life values were observed between doses. Changes in serum bilirubin levels were observed with a pattern similar to that commonly seen with oral administration of rifampicin.

BackgroundThe 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.MethodsA 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.ResultsIn 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.ConclusionsThe 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.
