RESUMEN

OBJECTIVES: In a period of important therapeutic changes in the field of haemophilia care, we provide updated statistics on children with severe haemophilia (0-12 years of age) in Italy. METHODS: Data presented are from the Italian National Registry of Congenital Coagulopathies (NRCC) - survey 2017. RESULTS: Children with severe Haemophilia A (HA) were 242, those with severe haemophilia B (HB) 48. Prophylaxis was adopted in 92.1% of individuals with severe HA and 88.6% with severe HB. Thirty-nine children (14.8%) were on treatment for inhibitors. FVIII prescribed to children with severe HA represented 11.1% of the total consumption, of which 4.6% was extended half-life (EHL). FIX given to children with HB accounted for 7.2% of the total FIX, of which 19.1% was EHL-FIX. CONCLUSION: The paediatric population analysed is characterized by a great adherence to therapy, so this data may constitute a benchmark for use of new, alternative therapies in the coming years.

RESUMEN

BACKGROUND: In Italy, the National Register of Congenital Coagulopathies (NRCC) collects epidemiological and therapeutic data from patients affected by haemophilia A (HA), haemophilia B (HB), von Willebrand's disease (vWD) and other rare coagulation disorders. Here we present data from the 2016 annual survey. MATERIALS AND METHODS: Data are provided by the Italian Haemophilia Centres, on a voluntary basis. Information flows from every Centre to a web-based platform of the Italian Association of Haemophilia Centres, shared with the Italian National Institute of Health, in accordance with current privacy laws. Patients are classified by diagnosis, disease severity, age, gender and treatment-related complications. RESULTS: In 2016, the total number of patients with congenital coagulopathies in the NRCC was 10,360: 39.8% of these patients had HA, 31.5% had vWD, 8.5% had HB, and 20.2% had less common factor deficiencies. The overall prevalence of HA and HB was 13.9/100,000 males and 3.0/100,000 males, respectively. The overall prevalence of vWD was 5.4/100,000 inhabitants. During 2016, 126 patients had current alloantibodies to factor VIII (FVIII) or factor IX (FIX) and were under treatment with bypassing agents and/or immune tolerance induction. Overall, 388 patients with a history of alloantibodies were recorded in the NRCC of whom 337 with severe HA and 12 with severe HB. Coagulation factor use, evaluated from treatment plans, was approximately 451,000,000 IU of FVIII for HA patients (7.5 IU/inhabitant), and approximately 53,000,000 IU of FIX for HB patients (0.9 IU/inhabitant). DISCUSSION: The prevalences of HA and HB fall within the ranges reported in more developed countries; the consumption of FVIII and FIX was in line with that of other European countries (France, United Kingdom) and Canada. The NRCC, with its bleeding disorder dataset, is a helpful tool for shaping public health policies, as well as planning clinical and epidemiological research projects.

RESUMEN

In Italy, the surveillance of people with bleeding disorders is based on the National Registry of Congenital Coagulopathies (NRCC) managed by the Italian National Institute of Health (Istituto Superiore di Sanità). The NRCC collects epidemiological and therapeutic data from the 54 Hemophilia Treatment Centers, members of the Italian Association of Hemophilia Centres (AICE). The number of people identified with bleeding disorders has increased over the years, with the number rising from approx. 7000 in 2000 to over 11,000 in 2015. The NRCC includes 4020 patients with hemophilia A and 859 patients with hemophilia B. The prevalence of the rare type 3 vWD is 0.20/100,000 inhabitants. Less common congenital bleeding disorders include the following deficiencies: Factor I (fibrinogen), Factor II (prothrombin), Factor V, Factor VII, Factor X, Factor XI and Factor XIII, which affect 1953 patients. Hepatitis C Virus (HCV) infection affects 1561 patients, more than 200 of whom have two infections (HCV + HIV). Estimated hemophilia-related drug consumption in 2015 was approx. 550 million IU of FVIII for hemophilia A patients and approx. 70 million IU of FIX for hemophilia B patients. The NRCC, with its bleeding disorder data set, is a tool that can provide answers to fundamental questions in public health, monitoring care provision and drug treatment, as well as facilitating clinical and epidemiological research.

RESUMEN

OBJECTIVE: The aim of this study was to assess the type and frequency of adverse events (AEs) in children with attention-deficit/hyperactivity disorder (ADHD) treated with methylphenidate or atomoxetine over a 5-year period in a large naturalistic study. METHODS: We draw on data from the Italian ADHD Registry, a national database for postmarketing phase IV pharmacovigilance of ADHD medications across 90 centers. AEs were defined as severe or mild as per the classification of the Italian Medicines Agency. AE frequency in the two treatment groups was compared using incidence rates per 100 person-years (IR100PY) and incidence rate ratios (IRRs). Mantel-Haenszel adjusted IRRs were calculated to control for psychiatric comorbidity. RESULTS: A total of 1350 and 753 participants (aged 6-18 years, mean age 10.7 ± 2.8) were treated with methylphenidate and atomoxetine, respectively, from 2007 to 2012. Ninety participants (7 %) were switched from methylphenidate to atomoxetine, and 138 (18 %) from atomoxetine to methylphenidate. Thirty-seven children treated with atomoxetine and 12 with methylphenidate had their medication withdrawn. Overall, 645 patients (26.8 %) experienced at least one mild AE (including decreased appetite and irritability, for both drugs) and 95 patients (3.9 %) experienced at least one severe AE (including severe gastrointestinal events). IR100PY were significantly higher in the atomoxetine-treated group compared with the methylphenidate-treated group for a number of mild and severe AEs and for any severe or mild AEs. After controlling for comorbidities, IRR was still significantly higher in the atomoxetine group compared with the methylphenidate group for a number of mild (decreased appetite, weight loss, abdominal pain, dyspepsia, stomach ache, irritability, mood disorder and dizziness) and severe (gastrointestinal, neuropsychiatric, and cardiovascular) AEs. CONCLUSIONS: In this naturalistic study, methylphenidate had a better safety profile than atomoxetine.

RESUMEN

OBJECTIVE: Attention deficit hyperactivity disorder (ADHD) is the most common psychiatric childhood disorder. The most commonly used drugs in the treatment of ADHD are methylphenidate (MPH) and atomoxetine (ATX); the former of the two is prescribed in USA more than it is in Western Europe. Some of the most important safety concerns about ADHD drug treatment are sudden cardiac death and suicidal behavior. In this study, we present a series of cases of Italian children who had presented suicidal ideation during ADHD pharmacological therapy with ATX. RESEARCH DESIGN AND METHODS: Data were obtained from the ADHD Italian Register. The data assessed the use of MPH and ATX, which had been prescribed to patients who were aged < 18 years and diagnosed with ADHD. All patients enrolled in the ADHD Italian Register treated with ATX or MPH who experienced suicidal thoughts or thoughts of self-harming were considered and assessed. RESULTS: We describe the clinical cases of seven Italian children (enrolled in the ADHD Italian Register) treated with ATX and affected by suicidal ideation, self-harming or other similar symptoms. Our results highlighted that all seven patients developed suicidal ideation or intentional self-harming during pharmaceutical treatment with ATX and, particularly, after the dose increase of the drug. CONCLUSION: There is a need to improve our knowledge about the efficacy and safety of ATX, MPH and other drugs used in the treatment of ADHD both in children and adults during the post-marketing experience.

RESUMEN

BACKGROUND: In Italy, basic health needs of patients with inherited bleeding disorders are met by a network of 50 haemophilia centres belonging to the Italian Association of Haemophilia Centres. Further emerging needs, due to the increased life expectancy of this patient group, require a multi-professional clinical management of the disease and provide a challenge to the organisation of centres.In order to achieve harmonised quality standards of haemophilia care across Italian Regions, an institutional accreditation model for haemophilia centres has been developed. MATERIAL AND METHODS: To develop an accreditation scheme for haemophilia centres, a panel of experts representing medical and patient bodies, the Ministry of Health and Regional Health Authorities has been appointed by the National Blood Centre. Following a public consultation, a technical proposal in the form of recommendations for Regional Health Authorities has been formally submitted to the Ministry of Health and has formed the basis for a proposal of Agreement between the Government and the Regions. RESULTS: The institutional accreditation model for Haemophilia Centres was approved as an Agreement between the Government and the Regions in March 2013. It identified 23 organisational requirements for haemophilia centres covering different areas and activities. DISCUSSION: The Italian institutional accreditation model aims to achieve harmonised quality standards across Regions and to implement continuous improvement efforts, certified by regional inspection systems. The identified requirements are considered as necessary and appropriate in order to provide haemophilia services as "basic healthcare levels" under the umbrella of the National Health Service. This model provides Regions with a flexible institutional accreditation scheme that can be potentially extended to other rare diseases.

RESUMEN

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.

RESUMEN

INTRODUCTION: Due to the increase in life expectancy, patients with haemophilia and other inherited bleeding disorders are experiencing age-related comorbidities that present new challenges. In order to meet current and emerging needs, a model for healthcare pathways was developed through a project funded by the Italian Ministry of Health. The project aimed to prevent or reduce the social-health burden of the disease and its complications. MATERIAL AND METHODS: The National Blood Centre appointed a panel of experts comprising clinicians, patients, National and Regional Health Authority representatives. Following an analysis of the scientific and regulatory references, the panel drafted a technical proposal containing recommendations for Regional Health Authorities, which has been formally submitted to the Ministry of Health. Finally, a set of indicators to monitor haemophilia care provision has been defined. RESULTS: In the technical document, the panel of experts proposed the adoption of health policy recommendations summarised in areas, such as: multidisciplinary integrated approach for optimal healthcare provision; networking and protocols for emergency care; home therapy; registries/databases; replacement therapy supply and distribution; recruitment and training of experts in bleeding disorders. The recommendations became the content of proposal of agreement between the Government and the Regions. Monitoring and evaluation of haemophilia care through the set of established indicators was partially performed due to limited available data. CONCLUSIONS: The project provided recommendations for the clinical and organisational management of patient with haemophilia. A particular concern was given to those areas that play a critical role in the comorbidities and complications prevention. Recommendations are expected to harmonise healthcare care delivery across regional networks and building the foundation for the national haemophilia network.

RESUMEN

OBJECTIVE: This study was conducted to assess the long-term effect of methylphenidate (MPH) or atomoxetine (ATX) on growth in attention-deficit/hyperactivity disorder (ADHD) drug-naïve children. DESIGN: The study was an observational, post-marketing, fourth phase study. METHODS: Data on height and weight were collected at baseline and every 6 months up to 24 months. RESULTS: Both ATX and MPH lead to decreased height gain (assessed by means of z-scores); the effect was significantly higher for ATX than for MPH. At any time, height z-score decrease in the ATX group was higher than the corresponding decrease observed in the MPH group, but the difference was significantly relevant only during the first year of treatment. An increment of average weight was observed both in patients treated with MPH and in those treated with ATX. However, using Tanner's percentile, a subset of patients showed a degree of growth lower than expected. This negative effect was significantly higher for ATX than for MPH. CONCLUSIONS: We conclude that ADHD drugs show a negative effect on linear growth in children in middle term. Such effect appears more evident for ATX than for MPH.

RESUMEN

INTRODUCTION: The Register was aimed at assessing the benefit-risk profile of the treatment of attention deficit hyperactivity disorder (ADHD) with atomoxetine and methylphenidate. METHODS: Post-marketing observational study, phase IV. Prescription medication to children and adolescents with ADHD aged between 6 and 18 years in the centres of reference for ADHD accredited by the Italian regions. RESULTS: In the period from September 2007 to October 2011, 1098 children and adolescents were treated with methylphenidate and 951 with atomoxetine. 411 (21.5%) patients are released from the register: 274 treated with atomoxetine and 167 with methylphenidate, with a greater risk of discontinuation for atomoxetine: RR 1.4 (1.3-1.6) p<0.001. The length of treatment at the time of removal from the register is 4.1 months for atomoxetine and 2 months for methylphenidate. Patients treated with atomoxetine are more likely to experience an adverse event compared to those treated with methylphenidate (RR 2.8; 1.9-4.2). The total number of serious adverse events observed was 110: 82 (75%) patients treated with atomoxetine and 28 (25%) individuals treated with methylphenidate. For 98 patients with serious adverse events, the adverse event led to the interruption of treatment with exit from the registry. The chance of a serious adverse event among those treated with atomoxetine compared to those with methylphenidate is RR 2.8 (1.8-4.2). There have been 14 cardiovascular events, all grown positively. 69 were found with a ECG alterations, with an increased risk for methylphenidate (RR 2.4; 1.4-4.2). The incidence of suicidal ideation was 4.5/1000 patients treated with atomoxetine. Hepatic alterations occurred with an incidence of 1/1000 subjects treated with methylphenidate and 4/1000 of those who received atomoxetine. DISCUSSION: The survey was carried out on a population which represents appropriately the paediatric population. The observed prevalence of ADHD corresponds to the expectation based on data from previous epidemiological investigations in Italy but considerably lower than what is reported in the international scientific literature. The rate of exposure to pharmacological treatments is similar to that of other European countries.

RESUMEN

OBJECTIVE: The purpose of this study was to assess the cardiovascular effects of drugs used for attention-deficit/hyperactivity disorder (ADHD) in children and adolescents treated in community care centers in Italy. METHODS: This study was an open, prospective, observational study of youth with ADHD treated with atomoxetine (ATX) and methylphenidate (MPH). Measurements of blood pressure and heart rate, and electrocardiogram (ECG) assessment were performed at baseline and at regular intervals up to 24 months. RESULTS: By June 2010, 1758 youth were enrolled in the Italian ADHD National Registry. Statistically significant increases were observed in cardiovascular measures: in the MPH group after 6 months in heart rate (+2.01, p = 0.01); in the ATX group after 6 months in diastolic pressure (+1.60, p = 0.01) and in heart rate (+2.93, p = 0.001), and after 12 months in heart rate (+3.26, p = 0.003). Compared with the baseline, 59 patients had an alteration of ECG during the follow-up period. Although at 12 months, the probability of detecting an abnormal ECG was higher in the MPH group than in the ATX group, only 2 out of 30 cases at 6 months with altered ECG were considered to have experienced serious adverse events. One case was treated with ATX and one with MPH, and arrhythmia was the detected abnormality. CONCLUSIONS: Treatment with MPH and ATX in youth appears to have a small but significant impact on the cardiovascular system. The long-term impact of these medications is unknown. Several clinically meaningless ECG alterations were observed mostly in MPH-treated youth. We therefore suggest evaluating cardiovascular risks at baseline.

RESUMEN

BACKGROUND: Transposable Elements (TEs) comprise nearly 45% of the entire genome and are part of sophisticated regulatory network systems that control developmental processes in normal and pathological conditions. The retroviral/retrotransposon gene machinery consists mainly of Long Interspersed Nuclear Elements (LINEs-1) and Human Endogenous Retroviruses (HERVs) that code for their own endogenous reverse transcriptase (RT). Interestingly, RT is typically expressed at high levels in cancer cells. Recent studies report that RT inhibition by non-nucleoside reverse transcriptase inhibitors (NNRTIs) induces growth arrest and cell differentiation in vitro and antagonizes growth of human tumors in animal model. In the present study we analyze the anticancer activity of Abacavir (ABC), a nucleoside reverse transcription inhibitor (NRTI), on PC3 and LNCaP prostate cancer cell lines. PRINCIPAL FINDINGS: ABC significantly reduces cell growth, migration and invasion processes, considerably slows S phase progression, induces senescence and cell death in prostate cancer cells. Consistent with these observations, microarray analysis on PC3 cells shows that ABC induces specific and dose-dependent changes in gene expression, involving multiple cellular pathways. Notably, by quantitative Real-Time PCR we found that LINE-1 ORF1 and ORF2 mRNA levels were significantly up-regulated by ABC treatment. CONCLUSIONS: Our results demonstrate the potential of ABC as anticancer agent able to induce antiproliferative activity and trigger senescence in prostate cancer cells. Noteworthy, we show that ABC elicits up-regulation of LINE-1 expression, suggesting the involvement of these elements in the observed cellular modifications.

RESUMEN

Chronic use of aspirin and statins has been associated with reduced risk of subsequent myocardial infarction (MI). However, in patients with chronic kidney disease (CKD), the cardioprotective role of aspirin and statins seems to be reduced. To evaluate the impact of chronic aspirin and statin use on clinical presentation of acute MI according to renal function, the authors retrospectively analyzed 595 consecutive patients admitted to our hospital for acute MI. Renal function was normal in 404 patients and impaired in 191. Patients on therapy (113 patients) were less likely to have ST-segment elevation MI (STEMI) compared with patients not treated (36% vs 53%, respectively, P=.0002). These results have been confirmed in the population of patients with CKD (48% of STEMI in patients receiving chronic therapy and 67% in patients without therapy,P=.01). Multivariate analysis in the group of patients with CKD showed that use of aspirin or statins was an independent predictor of a decreased probability of STEMI (odds ratio, 0.5; 95% confidence interval, 0.2-1.0,P=.05). The authors' results suggest that in a community-based sample of patients with acute MI, chronic aspirin and statin therapy has a cardioprotective role that is evident also in patients with CKD.

RESUMEN

BACKGROUND: Factors influencing the outcome of structured treatment interruptions (STIs) in HIV chronic infection are not fully elucidated. METHODS: In ISS-PART, 273 subjects were randomly assigned to arm A (137 assigned to continuous highly active antiretroviral therapy [HAART]) and arm B (136 assigned to 5 STIs of 1, 1, 2, 2, and 3 months' duration, each followed by 3 months of therapy). Main outcome measures were the proportion of subjects with a CD4 count >500 cells/mm3, the rate of virologic failure, and the emergence of resistance at 24 months. RESULTS: The proportion of subjects with a CD4 count >500 cells/mm3 was higher in arm A than in arm B (86.5% vs. 69.1%; P = 0.0075). Pre-HAART CD4 cell count and male gender were independent predictors of a CD4 count >500 cells/mm3 in arm B. The overall risk of virologic failure was not increased in arm B; however, it was higher in the 38 subjects who had resistance mutations in the rebounding virus. Archived mutations at baseline and the use of a regimen that included an unboosted protease inhibitor (PI), compared with nonnucleoside reverse transcriptase inhibitor-based HAART, independently predicted the emergence of plasma mutations during STI (P = 0.002 for DNA mutations and P = 0.048 for PI-based HAART). CONCLUSIONS: Our results suggest that patients with preexisting mutations and treated with unboosted PI-based HAART should not be enrolled in studies of time-fixed treatment interruptions, being at higher risk of developing plasma mutations during STI and virologic failure at therapy reinstitution.
