[Drugs for rare diseases: the blessing of being orphans.] / I farmaci per le malattie rare: la fortuna di essere orfani.

The incentives provided by Orphan Drugs Regulations have promoted the development of drugs that effectively ameliorate the course of serious conditions that had previously been neglected. However, the treatment of each individual patient with any of these drugs - the so-called 'orphan drugs' - is so expensive, that the total burden for publicly funded Health care Service is enormous and may become unsustainable. Italy is no exception, if it is to abide by its basic tenet of providing access to essential medicines - free of charge - to the entire population. We do not see any glimpses of improvement on the horizon: therefore we suggest that radical change must be introduced. First, price negotiation ought to take place at the European level, not at the member state level. Second, pricing should take into account not only value for patients, but also costs of research and development (R&D) plus production. Italian Medicines Agency (AIFA) should also support research focused on optimizing the effective use of orphan drugs in clinical practice. The challenges are complex: but AIFA is recognized as an authoritative body, and may be able to coagulate the agreement of other regulatory agencies for the ultimate purpose of achieving, for each of the orphan drugs a more reasonable 'European price'.

BRAF Signaling Pathway Inhibition, Podocyte Injury, and Nephrotic Syndrome.

Dabrafenib and trametinib, BRAF and MEK inhibitors, respectively, are effective targeted metastatic melanoma therapies, but little is known about their nephrotoxicity. Although tubulointerstitial injury has been the most widely reported renal side effect of targeted melanoma therapy, nephrotic syndrome has not been reported before. We report on a patient with metastatic melanoma who developed nephrotic syndrome during dabrafenib and trametinib treatment. Kidney biopsy showed diffuse loss of podocyte cytoarchitecture, extensive foot-process effacement, and glomerular endothelial injury. Kidney function and glomerular ultrastructural changes recovered fully after drug withdrawal. In vitro, BRAF inhibition decreased PLCε1 expression in podocytes, accompanied by a reduction in nephrin expression and an increase in permeability to albumin. Additionally, these drugs inhibited the podocyte-vascular endothelial growth factor (VEGF) system. In addition to implications for nephrotic syndrome pathophysiology, we suggest that patients given dabrafenib and trametinib be monitored closely for potential glomerular damage.

Social/economic costs and health-related quality of life in patients with histiocytosis in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with histiocytosis in Europe. METHODS: We conducted a cross-sectional study of patients with histiocytosis from France, Germany, Italy, Spain, Bulgaria, the UK, and Sweden. Data on demographic characteristics, health resource utilisation, informal care, loss of labour productivity and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. RESULTS: A total of 134 patients (35 France, 32 Germany, 30 Italy, 24 Spain, 7 Bulgaria, 4 UK and 2 Sweden) completed the questionnaire. The average annual costs ranged from € 6832 to € 33,283 between countries, the year of reference being 2012. Estimated direct healthcare costs ranged from € 1698 to € 18,213; direct nonhealthcare costs ranged from € 2936 to € 17,622 and labour productivity losses ranged from € 1 to € 8855. The mean EQ-5D score for adult histiocytosis patients was estimated at between 0.32 and 0.85, and the mean EQ-5D visual analogue scale score was estimated at between 50.00 and 66.50. CONCLUSION: The main strengths of this study lie in our bottom-up approach to costing and in the evaluation of histiocytosis patients from a broad perspective (societal costs). This type of analysis is very scarce in international literature for rare diseases in comparison with other illnesses. We conclude that histiocytosis patients incur considerable societal costs and experience substantial deterioration in HRQOL.

Social/economic costs and health-related quality of life in patients with cystic fibrosis in Europe.

OBJECTIVES: Our goal was to provide data on the economic burden and health-related quality of life (HRQOL) of patients with cystic fibrosis (CF) and their caregivers in Europe. METHODS: A cross-sectional study was carried out on adults and children with CF in eight European countries. Patients completed an anonymous questionnaire regarding their socio-demographic characteristics, use of healthcare services and presence of a caregiver. Costs were calculated with a bottom-up approach using unit costs from each participating country, and HRQOL was assessed using EQ-5D. The principal caregiver also answered a questionnaire on their characteristics, HRQOL and burden. RESULTS: A total of 905 patients with CF was included (399 adults and 506 children). The total average annual cost per patient varied from €21,144 in Bulgaria to €53,256 in Germany. Adults had higher direct healthcare costs than children, but children had much higher informal care costs (P < 0.0001). Total costs increased with patients' level of dependence. In adults, mean utility fell between 0.640 and 0.870, and the visual analogue scale ranged from 46.0 to 69.7. There was no difference in caregiver HRQOL regardless of whether they cared for an adult or a child. However, caregivers who looked after a child had a significantly higher burden (P = 0.0013). CONCLUSIONS: Our study highlights the burden of CF in terms of costs and decreased HRQOL for both patients and their caregivers throughout Europe.

Social/economic costs and quality of life in patients with haemophilia in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with haemophilia in Europe. METHODS: We conducted a cross-sectional study of patients with haemophilia from Bulgaria, France, Germany, Hungary, Italy, Spain Sweden and the UK. Data on demographic characteristics, health resource utilisation, informal care, loss of labour productivity and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. The costs have been estimated from a societal perspective adopting a bottom-up approach. RESULTS: A total of 401 questionnaires were included in the study, of which 339 were collected from patients with haemophilia and 62 from caregivers. The lowest average annual cost per person was reported in Bulgaria (€6,660) and the highest in Germany (€194,490). Our results demonstrate both a large difference from country to country in the average annual cost per patient in 2012 and the driving role of drugs in costs. Drugs represent nearly 90 % of direct healthcare costs in a majority of the countries analysed (Hungary, Italy, Spain and Germany). In Bulgaria, France and Sweden, however, healthcare services (visits, tests and hospitalisations) prevail. Costs are also shown to differ between children and adults. The mean EQ-5D index score for adult patients was 0.69 and mean EQ-5D VAS was 66.6. The mean EQ-5D index score for carers was 0.87 and mean EQ-5D VAS was 75.5. In the disability score, 60 % showed no disability and measuring caregiver burden with the Zarit Index produced an overall mean score of 25.3. CONCLUSION: We have shown that haemophilia is associated with a substantial economic burden and impaired HRQOL. Studies on cost of illness and HRQOL are important for haemophilia as the future of this disease is likely to change with the development of new innovative treatments. The introduction of these treatments will most likely impact future costs related to haemophilia.

Social/economic costs and health-related quality of life in patients with fragile X syndrome in Europe.

OBJECTIVE: To estimate the social/economic costs of fragile X syndrome (FXS) in Europe and to assess the health-related quality of life (HRQOL) of patients and caregivers. METHODS: A cross-sectional study was conducted in a sample of European countries. Patients were recruited through patients' associations. Data on their resource use and absence from the labour market were retrospectively obtained from an online questionnaire. Costs were estimated by a bottom-up approach and the EuroQol-5 Domain (EQ-5D) questionnaire was used to measure patients' and caregivers' HRQOL. RESULTS: Five countries were included in the analysis. The mean annual cost of FXS per patient varied from €4951 in Hungary to €58,862 in Sweden. Direct non-healthcare costs represented the majority of costs in all countries but there were differences in the share incurred by formal and informal care among those costs. Costs were also shown to differ between children and adults. Mean EQ-5D utility score for adult patients varied from 0.52 in France (n = 42) to 0.73 in Hungary (n = 2), while for caregivers this score was consistently inferior to 0.87. CONCLUSION: Our findings underline that, although its prevalence is low, FXS is costly from a societal perspective. They support the development of tailored policies to reduce the consequences of FXS on both patients and their relatives.

Social/economic costs and health-related quality of life of mucopolysaccharidosis patients and their caregivers in Europe.

OBJECTIVES: To assess the health-related quality of life (HRQOL) of patients with mucopolysaccharidosis (MPS) and their caregivers and to quantify the disease-related costs from a societal perspective. METHODS: In the context of a multi-country study of rare diseases (BURQOL-RD project), a cross-sectional survey was performed among MPS patients in seven European countries. Data on demographic characteristics, health resource utilization, informal care, and loss of labor productivity were collected. The EQ-5D, Barthel index (BI), and Zarit burden interview (ZBI) questionnaires were used to assess patients' and their informal caregivers' quality of life, patients' functional ability, and caregivers' burden, respectively. RESULTS: Altogether, 120 patients (children 62 %, females 40 %) and 66 caregivers completed the questionnaire. Patients' mean age was 16.5 years and median age at diagnosis was 3 years. Adult patients' average EQ-5D and EQ VAS scores varied across countries from 0.13 to 0.43 and 30.0 to 62.2, respectively, mean BI was 46.7, and ZBI was 32.7. Mean informal care time was 51.3 h/week. The mean total annual cost per patient (reference year 2012) was €24,520 in Hungary, €25,993 in France, €84,921 in Italy, €94,384 in Spain, and €209,420 in Germany. Costs are also shown to differ between children and adults. Direct costs accounted for most of the costs in all five countries (80, 100, 99, 98, and 93 %, respectively). CONCLUSIONS: MPS patients experience substantial loss of HRQOL and their families take a remarkable part in their care. Although utilization of health and social care resources varies significantly across countries, MPS incurs considerable societal costs in all the countries studied.

Social/economic costs and health-related quality of life in patients with epidermolysis bullosa in Europe.

BACKGROUND: The aim of this study was to determine the social/economic costs and health-related quality of life (HRQOL) of patients with epidermolysis bullosa (EB) in eight EU member states. METHODS: We conducted a cross-sectional study of patients with EB from Bulgaria, France, Germany, Hungary, Italy, Spain, Sweden and the United Kingdom. Data on demographic characteristics, health resource utilisation, informal care, labour productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. RESULTS: A total of 204 patients completed the questionnaire. Average annual costs varied from country to country, and ranged from €9509 to €49,233 (reference year 2012). Estimated direct healthcare costs ranged from €419 to €10,688; direct non-healthcare costs ranged from €7449 to €37,451 and labour productivity losses ranged from €0 to €7259. The average annual cost per patient across all countries was estimated at €31,390, out of which €5646 accounted for direct health costs (18.0 %), €23,483 accounted for direct non-healthcare costs (74.8 %), and €2261 accounted for indirect costs (7.2 %). Costs were shown to vary across patients with different disability but also between children and adults. The mean EQ-5D score for adult EB patients was estimated at between 0.49 and 0.71 and the mean EQ-5D visual analogue scale score was estimated at between 62 and 77. CONCLUSION: In addition to its negative impact on patient HRQOL, our study indicates the substantial social/economic burden of EB in Europe, attributable mostly to high direct non-healthcare costs.

Social/economic costs and health-related quality of life in patients with Duchenne muscular dystrophy in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with Duchenne muscular dystrophy (DMD) in Europe. METHODS: We conducted a cross-sectional study of patients with DMD from Bulgaria, France, Germany, Hungary, Italy, Spain, Sweden, and the UK. Data on demographic characteristics, healthcare resource utilization, informal care, labor productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. Costs have been estimated from a societal perspective adopting a bottom-up approach. RESULTS: A total of 422 questionnaires were included in the study; 268 of which were collected from patients with DMD and 154 from caregivers. The average annual cost per person in 2012 ranged from €7657 in Hungary to €58,704 in France. Direct non-healthcare costs are the main component of whole costs and informal care is the main driver of non-healthcare costs. Costs are also shown to differ between children and adults. With regard to HRQOL of adult patients, the EQ-5D VAS score and EQ-5D index scores were 50.5 and 0.24, respectively. The corresponding EQ-5D VAS and EQ-5D index scores for caregivers were 74.7 and 0.71, respectively. CONCLUSIONS: We have estimated the average annual cost per patient with DMD in eight European countries adopting a social perspective, and to our knowledge this is the first study with such a wide perspective. The results on costs show a considerable gap between Eastern and Western European countries. Non-healthcare costs range from 64 to 89 % of overall costs and informal care is to a great extent the main driver of this cost category. The HRQOL of people with DMD is much lower than that of the general population.

Social/economic costs and health-related quality of life in patients with scleroderma in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with systemic sclerosis (SSc; scleroderma) in Europe. METHODS: We conducted a cross-sectional study of patients with SSc (involving both localised and systemic sclerosis) from Germany, Italy, Spain, France, the UK, Hungary and Sweden. Data on demographic characteristics, healthcare resource utilisation, informal care, labour productivity losses and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. RESULTS: A total of 589 patients completed the questionnaire. The rate of patients with localised scleroderma, limited cutan and diffuse cutan SSc were 28, 68 and 4 %, respectively. Average annual costs varied from country to country and ranged from € 4607 to € 30,797 (reference year: 2012). Estimated direct healthcare costs ranged from € 1413 to € 17,300; direct non-healthcare costs ranged from € 1875 to € 4684 and labour productivity losses ranged from € 1701 to € 14,444. The mean EQ-5D index score for adult SSc patients varied from 0.49 to 0.75 and the mean EQ-5D visual analogue scale score was between 58.72 and 65.86. CONCLUSION: The main strengths of this study lie in our bottom-up approach to costing and our evaluation of SSs patients from a broad societal perspective. This type of analysis is very unusual in the international literature on rare diseases in comparison with other illnesses. We concluded that SSc patients incur considerable societal costs and experience substantial deterioration in HRQOL.

Social/economic costs and health-related quality of life in patients with Prader-Willi syndrome in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and health-related quality of life (HRQOL) of patients with Prader-Willi syndrome (PWS) in Europe. METHODS: We conducted a cross-sectional study of patients with PWS from Spain, Bulgaria, Hungary, Germany, Italy, the UK, Sweden and France. Data on demographic characteristics, healthcare resource utilisation, informal care, labour productivity losses and HRQOL were collected from questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) questionnaire. RESULTS: A total of 261 patients completed the questionnaire. The average annual costs ranged from € 3937 to € 67,484 between countries; the reference year for unit prices was 2012. Direct healthcare costs ranged from € 311 to € 18,760, direct non-healthcare costs ranged from € 1269 to € 44,035, and loss of labour productivity ranged from € 0 to € 2255. Costs were also shown to differ between children and adults. The mean EQ-5D index score for adult PWS patients ranged between 0.40 and 0.81 and the mean EQ-5D visual analogue scale score ranged between 51.25 and 90.00. CONCLUSION: The main strengths of this study lie in our bottom-up approach to costing and in the evaluation of PWS patients from a broad societal perspective. This type of analysis is very scarce in the international literature on rare diseases in comparison with other illnesses. We conclude that PWS patients incur considerable societal costs and experience substantial deterioration in HRQOL.

Dramatic effects of eculizumab in a child with diffuse proliferative lupus nephritis resistant to conventional therapy.

BACKGROUND: Treatment of systemic lupus erythematosus (SLE) with severe diffuse proliferative nephritis is often challenging, particularly in small children in whom a genetic conditioning is likely to play a role. The effectiveness of standard therapy based on glucocorticoid and immunosuppressive drugs is often unsatisfactory. CASE: A 4 year-old girl, whose parents were first-grade cousins of Moroccan ancestry, developed SLE that progressed to severe renal involvement despite standard therapy. She had persistently undetectable serum C4 levels and very low C3 levels (<30 mg/dl), and extremely high anti-DNA titers (>1:640) that remained unmodified during 2 years of follow-up. No mutations of genes encoding for complement inhibitors were detected. Despite aggressive therapy based on prednisone, plasma exchanges, and cyclosporine, the child worsened and eventually developed features of atypical hemolytic uremic syndrome (aHUS). Treatment with eculizumab provided prompt remission of vasculitis, proteinuria, and hematuria, with normalization of renal function. Two attempts to withdraw eculizumab were followed by severe relapses and rescued by reinstating treatment. The child has been treated with eculizumab for > 17 months without relevant side effects. CONCLUSION: C5 inhibition by eculizumab completely reversed clinical symptoms and laboratory renal signs of severe lupus nephritis. Blocking complement-system activation with the use of targeted drugs may be a new and exciting strategy to treat SLE patients unresponsive to conventional therapy.

Eliminating treatable deaths due to acute kidney injury in resource-poor settings.

Acute kidney injury (AKI) is imposing a severe burden of morbidity and mortality both in developed and developing countries. Also AKI has a major economic impact on healthcare expenditure. This is particularly so in poor countries where AKI especially impacts young productive people, imposing severe penury upon their families. The mission is to lessen the high burden in terms of death consequent to this disorder in low-resource regions, which in many cases is preventable and treatable with simple measures. The International Society of Nephrology has launched a long-term program, called "0 by 25", which advocates that zero people should die of untreated AKI in the poorest part of Africa, Asia, and Latin America by 2025. This paper illustrates how the project will be developed.

Immunosuppressive treatment for idiopathic membranous nephropathy in adults with nephrotic syndrome.

BACKGROUND: Idiopathic membranous nephropathy (IMN) is the most common form of nephrotic syndrome in adults. The disease shows a benign or indolent course in the majority of patients, with a rate of spontaneous complete or partial remission of nephrotic syndrome as high as 30% or more. Despite this, 30% to 40% of patients progress toward end-stage kidney disease (ESKD) within five to 15 years. The efficacy and safety of immunosuppression for IMN with nephrotic syndrome are still controversial. This is an update of a Cochrane review first published in 2004. OBJECTIVES: The aim of this review was to evaluate the safety and efficacy of immunosuppressive treatments for adult patients with IMN and nephrotic syndrome. Moreover it was attempted to identify the best therapeutic regimen, when to start immunosuppression and whether the above therapies should be given to all adult patients at high risk of progression to ESKD or only restricted to those with impaired kidney function. SEARCH METHODS: We searched Cochrane Renal Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Chinese databases, reference lists of articles, and clinical trial registries to June 2014. We also contacted principal investigators of some of the studies for additional information. SELECTION CRITERIA: Randomised controlled trials (RCTs) investigating the effects of immunosuppression in adults with IMN and nephrotic syndrome. DATA COLLECTION AND ANALYSIS: Study selection, data extraction, quality assessment, and data synthesis were performed using the Cochrane-recommended methods. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) and 95% CI for continuous outcomes. MAIN RESULTS: Thirty nine studies with 1825 patients were included, 36 of these could be included in our meta-analyses. The data from two studies could not be extracted and one study was terminated due to poor accrual. Immunosuppression significantly reduced all-cause mortality or risk of ESKD ((15 studies, 791 patients): RR 0.58 (95% CI 0.36 to 0.95, P = 0.03) and risk of ESKD ((15 studies, 791 patients): RR 0.55, 95% CI 0.31 to 0.95, P = 0.03), increased complete or partial remission ((16 studies, 864 patients): RR 1.31, 95% CI 1.01 to 1.70, P = 0.04), and decreased proteinuria ((9 studies,(393 patients): MD -0.95 g/24 h, 95% CI -1.81 to -0.09, P = 0.03) at the end of follow-up (range 6 to 120 months). However this regimen was associated with more discontinuations or hospitalisations ((16 studies, 880 studies): RR 5.35, 95% CI 2.19 to 13.02), P = 0.0002). Combined corticosteroids and alkylating agents significantly reduced death or risk of ESKD ((8 studies, 448 patients): RR 0.44, 95% CI 0.26 to 0.75, P = 0.002) and ESKD ((8 studies, 448 patients): RR 0.45, 95% CI 0.25 to 0.81, P = 0.008), increased complete or partial remission ((7 studies, 422 patients): RR 1.46, 95% CI 1.13 to 1.89, P = 0.004) and complete remission ((7 studies, 422 patients): RR 2.32, 95% CI 1.61 to 3.32, P < 0.00001), and decreased proteinuria ((6 studies, 279 patients): MD -1.25 g/24 h, 95% CI -1.93 to -0.57, P = 0.0003) at the end of follow-up (range 9 to 120 months). In a population with an assumed risk of death or ESKD of 181/1000 patients, this regimen would be expected to reduce the number of patients experiencing death or ESKD to 80/1000 patients (range 47 to 136). In a population with an assumed complete or partial remission of 408/1000 patients, this regimen would be expected to increase the number of patients experiencing complete or partial remission to 596/1000 patients (range 462 to 772). However this combined regimen was associated with a significantly higher risk of discontinuation or hospitalisation due to adverse effects ((4 studies, 303 patients): RR 4.20, 95% CI 1.15 to 15.32, P = 0.03). Whether this combined therapy should be indicated in all adult patients at high risk of progression to ESKD or only restricted to those with deteriorating kidney function still remained unclear. Cyclophosphamide was safer than chlorambucil ((3 studies, 147 patients): RR 0.48, 95% CI 0.26 to 0.90, P = 0.02). There was no clear evidence to support the use of either corticosteroid or alkylating agent monotherapy. Cyclosporine and mycophenolate mofetil failed to show superiority over alkylating agents. Tacrolimus and adrenocorticotropic hormone significantly reduced proteinuria. The numbers of corresponding studies related to tacrolimus, mycophenolate mofetil, adrenocorticotropic hormone, azathioprine, mizoribine, and Tripterygium wilfordii are still too sparse to draw final conclusions. AUTHORS' CONCLUSIONS: In this update, a combined alkylating agent and corticosteroid regimen had short- and long-term benefits on adult IMN with nephrotic syndrome. Among alkylating agents, cyclophosphamide was safer than chlorambucil. This regimen was significantly associated with more withdrawals or hospitalisations. It should be emphasised that the number of included studies with high-quality design was relatively small and most of included studies did not have adequate follow-up and enough power to assess the prespecified definite endpoints. Although a six-month course of alternating monthly cycles of corticosteroids and cyclophosphamide was recommended by the KDIGO Clinical Practice Guideline 2012 as the initial therapy for adult IMN with nephrotic syndrome, clinicians should inform their patients of the lack of high-quality evidence for these benefits as well as the well-recognised adverse effects of this therapy. Cyclosporine or tacrolimus was recommended by the KDIGO Clinical Practice Guideline 2012 as the alternative regimen for adult IMN with nephrotic syndrome; however, there was no evidence that calcineurin inhibitors could alter the combined outcome of death or ESKD.

The social burden and quality of life of patients with haemophilia in Italy.

BACKGROUND: In Italy, the project on the social burden and quality of life (QoL) of patients with haemophilia investigates costs from a society perspective and provides an overview of their quality of life. Moreover, as life expectancy increased in recent years along with new treatment strategies implemented in the last decades, it analyses trends of costs other than drugs simulating impacts during patient whole life. MATERIAL AND METHODS: We ran a web-based cross-sectional survey supported by the Italian Federation of Haemophilia Societies in recruiting patients with haemophilia and their caregivers. We developed a questionnaire to collect information on demographic characteristics, healthcare and social services consumption, formal and informal care utilisation, productivity loss and quality of life. In particular, quality of life was assessed through the EuroQoL tool. Last, we applied the illness cost method from a society perspective. RESULTS: On average, quality of life is worse in adult patients compared to child and caregivers: more than 75% of adult patients declare physical problems, 43% of adult patients and 54% of their parents have anxiety problems. Assuming a society perspective, the estimated mean annual total cost per patient in 2012 is 117,732 €. Drugs represent 92% of total costs. Focusing on costs other than drugs, each additional point of EuroQoL tool implies a costs' reduction of 279 €. The impact of age varies across age groups: each added year implies a total decrease of costs up to 46.6 years old. Afterwards, every additional year increases costs. DISCUSSION: Quality of life of patients with haemophilia and their caregivers improved and it influences positively on consumed resources and on their contribution to the social-economic system. Costs other than drugs for patients with haemophilia follow the same trends of general population.

Kidney failure: aims for the next 10 years and barriers to success.

Although in some parts of the world acute and chronic kidney diseases are preventable or treatable disorders, in many other regions these diseases are left without any care. The nephrology community needs to commit itself to reduction of this divide between high-income and low-income regions. Moreover, new and exciting developments in fields such as pharmacology, genetic, or bioengineering, can give a boost, in the next decade, to a new era of diagnosis and treatment of kidney diseases, which should be made available to more patients.

Immunosuppression for membranous nephropathy: a systematic review and meta-analysis of 36 clinical trials.

BACKGROUND AND OBJECTIVES: The efficacy and safety of immunosuppression for idiopathic membranous nephropathy (IMN) with nephrotic syndrome are still controversial. A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The Cochrane Library, PUBMED, EMBASE, Chinese Database, and Clinical Trial Registries (June 2012) were searched to identify RCTs investigating the effect of immunosuppression on adults with IMN and nephrotic syndrome. RESULTS: This review was an update (36 RCTs, 1762 participants) of the 2004 version (18 RCTs, 1025 participants). Immunosuppression significantly reduced all-cause mortality or ESRD (15 RCTs, 791 participants; risk ratio, 0.58 [95% confidence interval, 0.36-0.95]; P=0.03). However, the result was not consistent when prespecified subgroup analyses were undertaken. Immunosuppression increased complete or partial remission (CR + PR) (16 RCTs, 864 participants; 1.31 [1.01-1.70]; P=0.04) but resulted in more withdrawals or hospitalizations (16 RCTs, 880 participants; 5.35 [2.19-13.02]; P=0.002). Corticosteroids combined with alkylating agents significantly reduced all-cause mortality or ESRD (8 RCTs, 448 participants; 0.44 [0.26-0.75]; P=0.002) and increased CR + PR (7 RCTs, 422 participants; 1.46 [1.13-1.89]; P=0.004) but led to more adverse events (4 RCTs, 303 participants; 4.20 [1.15-15.32]; P=0.03). Cyclophosphamide was safer than chlorambucil (3 RCTs, 147 participants; 0.48 [0.26-0.90]; P=0.02). Cyclosporine and mycophenolate mofetil failed to show superiority over alkylating agents. Tacrolimus and adrenocorticotropic hormone significantly reduced proteinuria. CONCLUSIONS: Alkylating agents plus corticosteroids had long-term and short-term benefits for adult IMN, but resulted in more withdrawals or hospitalizations.
