Psoriasis is a chronic infl ammatory, immune-mediated skin disorder that affects 1.5-1.8 million people in Italy. The most common form of the disease is chronic plaque psoriasis, affecting about 90% of psoriasis patients, with about 20%-30% of them suffering from a moderate or severe condition. Little information is available about the economic impact of psoriasis in European countries. The primary objective of this study was to perform a cost-ofillness analysis of patients with moderate and severe plaque psoriasis in Italy. Therefore, direct, indirect costs, and intangible costs (quality of life -QoL) were assessed. In this national, multicenter, prospective, 3-month cost-of-illness study of moderate and severe plaque psoriasis, direct and indirect costs were assessed from the patient, third-party payer (National Health Service, NHS), and societal perspectives. From November 2003 to October 2004 consecutive patients were enrolled over a 1-year period, in order to minimize seasonal fl uctuations in disease severity. 150 patients enrolled in 6 investigational sites in Italy, completed the study, and were eligible to be analyzed according to the study protocol. Intangible costs (QoL) were measured using SF36 and DLQI questionnaires. The mean total cost for psoriasis (average Psoriasis Area Severity Index [PASI] score 21.4), including direct and indirect items, was 8,371.61 per patient per year. The mean cost for patients with moderate disease (PASI Յ 20) was 5,226.04, while the mean cost for patients with more severe disease (PASI Ͼ 20) was 11,434.40 per year. Disease heavily affected QoL measured using SF36, and the impairment was greater in patients affected by a more severe form of disease. Moderate and severe plaque psoriasis is associated with extremely high costs, which are related to disease severity. Data from this study show that the more severe plaque psoriasis, the higher the direct and indirect costs for its management. Direct costs are higher than indirect costs; hospitalization represents the most signifi cant item, accounting for 30% of the total expenses. QoL in moderate and severe plaque psoriasis is low compared with the population at large, confi rming the high impact of plaque psoriasis on QoL. The relatively high average annual costs per patient point to the need for a more effi cient and long-term control of psoriasis.
Background and ObjectivesBiologic therapies are considered to be cost effective by leading Health Technology Assessment (HTA) agencies and, therefore, eligible for reimbursement by public health services. However, biologic therapies entail sizable incremental costs and, besides, have a considerable financial impact that in Italy amounts to 13.7 % of the national health service’s pharmaceutical expenditure. In the reimbursability decision process, an important role is played by both the drug efficacy data observed in pre-licensing RCTs and the economic modelling assumptions, as they give evidence on cost effectiveness. The administration of therapies in real practice settings is likely to produce a significant deviation from the results predicted by the models, theoretically outweighing the assumption on which the decision process is founded. This is a matter of concern for public health services and, consequently, an interesting topic to investigate.MethodsTo overcome the lack of knowledge concerning the actual cost effectiveness of biologic therapies for the treatment of plaque psoriasis in the clinical practice setting in Italy, an observational study was conducted in 12 specialist centres on patients switching to biologic therapy within a 6-month enrolment window.ResultsThe study confirms in clinical practice the efficacy of the switch to biologic therapies, analysed using a number of clinical [Psoriasis Area and Severity Index (PASI), pain visual analogue scale (VAS) and itching VAS] and quality-of-life parameters. A general health-related quality of life (HR-QOL) improvement, with a 0.23 quality-adjusted life-year (QALY) mean gain per patient, has been reported in the 6-month observation period. The direct medical costs to treat plaque psoriasis with biologic therapies amount to €15,073.7 per year (prior to their enrolment, the same patients cost €2,166.2 on an annual basis). After the switch to biologic agents, the cost per QALY during the first year of treatment amounts to €28,656.3.ConclusionAt least in the short-term, the clinical practice of the specialised Italian centres taking part in the study confirms that switching patients to a biologic drug produces an incremental cost-effectiveness ratio comparable with the values predicted by the HTA bodies.
The cost-effectiveness of biological treatments for psoriasis is not well determined and may vary from country to country. The objectives of this study was to perform a cost-effectiveness analysis of infliximab compared with other anti-tumor necrosis factor-alpha agents for the treatment of psoriasis in Italy. The incremental cost-effectiveness ratio per patients achieving at least 75% improvement in the psoriasis area and severity index assessed over 24- and 48-50-week periods was calculated. Efficacy data were drawn from randomized controlled trials when available or from open label studies. Considering patients achieving psoriasis area and severity index at week 24 and 48-50, infliximab was dominant (more effective and less costly) over etanercept given at 50 mg twice weekly. In contrast, infliximab was not dominant over etanercept at other dosages or over adalimumab. When considering the impact of therapy on quality of life at Week 12 using the Dermatology Life Quality Index equal to zero, infliximab resulted more effective and less costly than etanercept. Therefore, infliximab seems to be cost-effective in the therapy of psoriasis. Further cost-efficacy evaluations based on head-to-head trials are necessary to address health economic considerations.
Our results demonstrate a higher efficacy and more rapid onset of action with the two-compound ointment compared with calcipotriol cream alone in short-term treatment. However, sequential application of calcipotriol allows maintenance of the results.
Background Psoriasis (Ps) is a chronic systemic autoimmune disease associated with pruritus in 64–98% of patients. However, few modestly sized studies assess factors associated with psoriatic pruritus. Objective To investigate factors associated with Ps pruritus intensity. Methods Psoriasis patients 18 years or older seen in one of 155 centres in Italy between September 2005 and 2009 were identified from the Italian PsoCare registry. Patients without cutaneous psoriasis and those with missed information on pruritus were excluded. Results We identified 10 802 patients, with a mean age 48.8 ± 14.3 years. Mild itch was present in 33.2% of patients, moderate in 34.4%, severe in 18.7% and very severe in 13.7%. Higher itch intensity was associated with female gender, lower educational attainment compared to university degree, pustular psoriasis, psoriasis on the head, face, palmoplantar areas, folds and genitalia, more severe disease, disease duration <15 years, and no or few prior systemic treatments. Limitations Effects of specific medication on itch were not assessed. Conclusions Pruritus should be evaluated during psoriasis visits, and physicians should be aware of patients at higher risk for itch. Further studies are needed to assess the effects of medications on itch, and establish therapy for psoriasis patients with persistent itch.
