RESUMEN
PURPOSE: Intravenous trastuzumab, pertuzumab, and docetaxel are first-line standard of care for patients with HER2-positive metastatic breast cancer (mBC). MetaPHER is the first study assessing the safety and tolerability of subcutaneous trastuzumab plus intravenous pertuzumab and chemotherapy in a global patient population with HER2-positive mBC. METHODS: In this open-label, single-arm, multicenter, phase 3b study, eligible patients were ≥ 18 years old with histologically/cytologically confirmed previously untreated HER2-positive mBC. All received ≥ 1 subcutaneous trastuzumab 600 mg fixed dose plus intravenous pertuzumab (loading dose: 840 mg/kg; maintenance: 420 mg/kg) and docetaxel (≥ 6 cycles; initial dose 75 mg/m2) every 3 weeks. The primary objective was safety and tolerability; secondary objectives included efficacy. RESULTS: At clinical cutoff, 276 patients had completed the study; median duration of follow-up was 27 months. The most common any-grade adverse events were diarrhea, alopecia, and asthenia; the most common grade ≥ 3 events were neutropenia, febrile neutropenia, and hypertension. There were no cardiac deaths and mean left ventricular ejection fraction was stable over time. Median investigator-assessed progression-free survival was 18.7 months; objective response rate was 75.6%. CONCLUSIONS: Safety and efficacy with subcutaneous trastuzumab plus intravenous pertuzumab and docetaxel in mBC are consistent with historical evidence of intravenous trastuzumab with this combination. Findings further support subcutaneous administration not affecting safety/efficacy profiles of trastuzumab in HER2-positive BC with increased flexibility in patient care. A fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection has recently been approved for the treatment of HER2-positive early/mBC, further addressing the increasing relevance of and need for patient-centric treatment strategies. TRIAL REGISTRATION: NCT02402712.

OBJECTIVE: To investigate the care management and continuity from child to adult mental health service for young adults with ADHD. METHOD: A questionnaire survey from 18 Regional ADHD Pediatric Centers (RAPC) in Lombardy, Italy, was used to collect data on transition protocols and population served, and to track the pathway of care of ADHD patients once they reached adulthood. RESULTS: Twenty-eight percent of RAPC had transition protocols and 3% of the population annually served were potential referrals to adult service. Of 52 patients who turned 18 years, just over 70% were monitored by the general practitioner, of those 5 with RAPC support. One fifth of patients continued to use mental health services, the majority was still monitored by the RAPC, and only three by services for adult. CONCLUSION: Managing the process of transition to adult services in mental health care remains a need to be prioritized and better defined for ADHD patients.

To compare the utilization of health care resources (drug prescriptions, hospital admissions and health care services) by immigrant versus native elderly people (65 years or more), by using administrative database of the Lombardy Region. For each immigrant (an older people born out of Italy), one person born in Lombardy (native) was randomly selected and matched by age, sex and general practitioner. The 25,508 immigrants selected were less prescribed with at least one drug (OR 0.72, 95 % CI 0.67-0.76) and had a lesser use of health care services (OR 0.79, 95 % CI 0.75-0.84) than natives. No statistically significant differences were found for hospital admission rates (OR 0.99, 95 % CI 0.99-1.04). A lower rate of health care resource utilization was observed in elderly immigrants who had been living in the host region for as many as 10 years.

BACKGROUND: Traditional faecal-based methods have poor sensitivity for the detection of S. stercoralis, therefore are inadequate for post-treatment evaluation of infected patients who should be carefully monitored to exclude the persistence of the infection. In a previous study, we demonstrated high accuracy of five serology tests for the screening and diagnosis of strongyloidiasis. Aim of this study is to evaluate the performance of the same five tests for the follow up of patients infected with S. stercoralis. METHODS: Retrospective study on anonymized, cryo-preserved samples available at the Centre for Tropical Diseases (Negrar, Verona, Italy). Samples were collected before and from 3 to 12 months after treatment. The samples were tested with two commercially-available ELISA tests (IVD, Bordier), two techniques based on a recombinant antigen (NIE-ELISA and NIE-LIPS) and one in-house IFAT. The results of each test were evaluated both in relation to the results of fecal examination and to those of a composite reference standard (classifying as positive a sample with positive stools and/or at least three positive serology tests). The associations between the independent variables age and time and the dependent variable value of serological test (for all five tests), were analyzed by linear mixed-effects regression model. RESULTS: A high proportion of samples demonstrated for each test a seroreversion or a relevant decline (optical density/relative light units halved or decrease of at least two titers for IFAT) at follow up, results confirmed by the linear mixed effects model that showed a trend to seroreversion over time for all tests. In particular, IVD-ELISA (almost 90% samples demonstrated relevant decline) and IFAT (almost 87%) had the best performance. Considering only samples with a complete negativization, NIE-ELISA showed the best performance (72.5% seroreversion). CONCLUSIONS: Serology is useful for the follow up of patients infected with S. stercoralis and determining test of cure.

Better results have been recently reported in clinical pancreatic islet transplantation (ITX) due mostly to improved isolation techniques and immunosuppression; however, some limitations still exist. It is known that following transplantation, 30% to 60% of the islets are lost. In our study, we have investigated 1) the role of size as a factor affecting islet engraftment and 2) potential procedural manipulations to increase the number of smaller functional islets that can be transplanted. C57/BL10 mice were used as donors and recipients in a syngeneic islet transplant model. Isolated islets were divided by size (large, >300 µm; medium 150-300 µm; small, <150 µm). Each size was transplanted in chemically induced diabetic mice as full (600 IEQ), suboptimal (400 IEQ), and marginal mass (200 IEQ). Control animals received all size islets. Engraftment was defined as reversal of diabetes by day 7 posttransplantation. When the superiority of smaller islets was observed, strategies of overdigestion and fragmentation were adopted during islet isolation in the attempt to reduce islet size and improve engraftment. Smaller islets were significantly superior in engraftment compared to medium, large, and control (all sizes) groups. This was more evident when marginal mass data were compared. In all masses, success decreased as islet size increased. Once islets were engrafted, functionality was not affected by size. When larger islets were fragmented, a significant decrease in islet functionality was observed. On the contrary, if pancreata were slightly overdigested, although not as successful as small naive islets, an increase in engraftment was observed when compared to the control group. In conclusion, smaller islets are superior in engraftment following islet transplantation. Fragmentation has a deleterious effect on islet engraftment. Islet isolations can be performed by reducing islet size with slight overdigestion, and it can be safely adopted to improve clinical outcome.

OBJECTIVE: The goal of this study was to evaluate the effectiveness of nebulized beclomethasone in preventing the recurrence of viral wheezing. METHODS: The study was designed as a randomized, double-blind, placebo-controlled trial. Outpatient children aged 1 to 5 years with at least 1 episode of viral wheezing in the last 12 months, presenting to any of 40 Italian pediatricians for an upper respiratory tract infection, were randomly allocated to receive beclomethasone 400 µg or placebo twice daily for 10 days. Medications were administered through a nebulizer. A clinical evaluation was performed by the pediatrician at the start and end of the treatment period. A subjective evaluation of symptoms and efficacy of treatment was performed by the parents. The primary endpoint was the incidence of viral wheezing diagnosed by the pediatricians during the 10-day treatment period. RESULTS: A total of 525 children were enrolled in the study, 521 of whom were visited at the end of the treatment period. Wheezing was diagnosed by the pediatricians in 47 children (9.0% [95% confidence interval: 6.7 to 11.3]), with no statistically significant differences between treatment groups (beclomethasone versus placebo relative risk: 0.61 [95% confidence interval: 0.35 to 1.08]).The treatment was considered helpful by 63% of parents (64% in the beclomethasone group vs 61% in the placebo group). In all, 46% of children still had infection symptoms at the end of the treatment period, with no differences between groups. CONCLUSIONS: The findings from this study confirm that inhaled steroids are not effective in preventing recurrence of viral wheezing. Moreover, no benefits were found in reducing symptoms of respiratory tract infections.

BACKGROUND: The diagnosis of Strongyloides stercoralis (S. stercoralis) infection is hampered by the suboptimal sensitivity of fecal-based tests. Serological methods are believed to be more sensitive, although assessing their accuracy is difficult because of the lack of sensitivity of a fecal-based reference ("gold") standard. METHODS: The sensitivity and specificity of 5 serologic tests for S. stercoralis (in-house IFAT, NIE-ELISA and NIE-LIPS and the commercially available Bordier-ELISA and IVD-ELISA) were assessed on 399 cryopreserved serum samples. Accuracy was measured using fecal results as the primary reference standard, but also using a composite reference standard (based on a combination of tests). RESULTS: According to the latter standard, the most sensitive test was IFAT, with 94.6% sensitivity (91.2-96.9), followed by IVD-ELISA (92.3%, 87.7-96.9). The most specific test was NIE-LIPS, with specificity 99.6% (98.9-100), followed by IVD-ELISA (97.4%, 95.5-99.3). NIE-LIPS did not cross-react with any of the specimens from subjects with other parasitic infections. NIE-LIPS and the two commercial ELISAs approach 100% specificity at a cut off level that maintains ≥70% sensitivity. CONCLUSIONS: NIE-LIPS is the most accurate serologic test for the diagnosis of S. stercoralis infection. IFAT and each of the ELISA tests are sufficiently accurate, above a given cut off, for diagnosis, prevalence studies and inclusion in clinical trials.

Many hospitalizations for asthma could potentially be avoided with appropriate management. The aim of this study was to analyze data on disease management of a paediatric population with a hospitalization for asthma. The study population comprised 6-17 year old subjects belonging to three local health units of the Lombardy Region, northern Italy. Regional administrative databases were used to collect data on: the number of children with an incident hospitalization for asthma during the 2004-2006 period, anti-asthma therapy, specialist visit referrals, and claims for spirometry, released in the 12 months before and after hospitalization. Each patient's asthma management profile was compared with GINA guideline recommendations. Among the 183 hospitalized subjects, 101 (55%) received therapy before hospitalization and 82 (45%) did not. 10% did not receive any therapy either before or after hospital admission and in 13% the therapy was discontinued afterward. Based on GINA guidelines, asthma management adhered to recommendations only for 55% of subjects. Results may suggest that for half of hospitalized subjects, inaccurate diagnosis, under-treatment/scarce compliance with asthma guidelines by physicians, and/or scarce compliance to therapy by patients/their parents occurred. In all these cases, hospitalization would be a proxy indicator of preventable poor control of disease, rather than a proxy indicator of severity.

Meta-analyses have found conflicting evidence on the link between antipsychotics and cerebrovascular events (CVEs). The primary aim of this study was to evaluate the association between any antipsychotic prescription and CVEs in Italian elderly; second, to compare the effect of typical and atypical antipsychotics on CVEs; and third, to investigate the effect of antipsychotics on CVEs in the subgroup of persons coprescribed with acetylcholinesterase inhibitors (AChEIs). Administrative claims from community-dwelling people aged 65 to 94 years living in Northern Italy were analyzed using a retrospective case-control design, from 2003 to 2005. The primary outcome measure was a hospital discharge diagnosis of CVEs during 2005. Four age-, sex-, and local health unit-matched control subjects were identified for each case. Antihypertensive drugs, anticoagulants, platelet inhibitors, antidiabetic drugs, lipid-lowering drugs, and AChEI were used as covariates in conditional logistic regression models testing the odds ratio (OR) for CVEs due to antipsychotics use. Three thousand eight hundred fifty-five cases of CVEs were identified and matched with 15,420 control subjects. In multiadjusted models, the association of any antipsychotics, typical or atypical with CVEs, was not significant. When antipsychotics were categorized according to the number of boxes prescribed during the observational period, being prescribed with at least 19 boxes of typical antipsychotics was significantly associated with CVEs (OR, 2.4; 95% confidence interval, 1.08-5.5). An interaction was found between any antipsychotic and AChEI coprescription on CVEs (OR, 0.46; 95% confidence interval, 0.23-0.92). In conclusion, only typical antipsychotics were associated with an increased odd of CVEs, but the association was duration dependent. Persons prescribed simultaneously with AChEI and antipsychotics may be at a lower risk of CVEs.

PURPOSE: To describe the use of ciprofloxacin and fluconazole for the treatment of sepsis in European neonatal intensive care units (NICUs) in order to better orient research aimed at acquiring essential knowledge in this critical area. METHODS: The survey consisted of an online questionnaire for all participating NICUs on treatment schemes employed, rationales behind drug choices and interest in participation in research involving the two drugs. RESULTS: A total of 189 level II and III NICUs participated in the survey, representing 25 countries, with Italy, UK and France providing the greatest number of centres (54 % of total). Ciprofloxacin is used in 25 % of NICUs that responded, although the indications for administering it vary between centres and the dosage ranges vary considerably, with 25 % of NICUs giving ≤10 mg/kg/day and another 25 % giving ≥21 mg/kg/day. Factors given as affecting the decision to use ciprofloxacin are uncertainty about its safety and pharmacokinetics and level of penetration in the cerebrospinal fluid. Among the 70 % of responding units that use fluconazole to treat fungal infection, 45 % administer 6 mg/kg unit doses while 33 % administer 12 mg/kg; 41 % of NICUs use a 24-h interval between administrations while 20 % wait 72 h. Among the responding NICUs, 57 % were willing to participate in a project on ciprofloxacin and 59 % would consider participating in a randomized controlled trial evaluating fluconazole versus micafungin. CONCLUSIONS: Great variability in therapies exists within and between countries. Numerous centres are interested in participating in research on these drugs, highlighting the need for further knowledge on sepsis treatment and European centres' interest in off-patent medicine research.

PURPOSE: To evaluate the quality of data reporting and statistical methods performed in drug utilization studies in the pediatric population. METHODS: Drug utilization studies evaluating all drug prescriptions to children and adolescents published between January 1994 and December 2011 were retrieved and analyzed. For each study, information on measures of exposure/consumption, the covariates considered, descriptive and inferential analyses, statistical tests, and methods of data reporting was extracted. An overall quality score was created for each study using a 12-item checklist that took into account the presence of outcome measures, covariates of measures, descriptive measures, statistical tests, and graphical representation. RESULTS: A total of 22 studies were reviewed and analyzed. Of these, 20 studies reported at least one descriptive measure. The mean was the most commonly used measure (18 studies), but only five of these also reported the standard deviation. Statistical analyses were performed in 12 studies, with the chi-square test being the most commonly performed test. Graphs were presented in 14 papers. Sixteen papers reported the number of drug prescriptions and/or packages, and ten reported the prevalence of the drug prescription. The mean quality score was 8 (median 9). Only seven of the 22 studies received a score of ≥10, while four studies received a score of <6. CONCLUSIONS: Our findings document that only a few of the studies reviewed applied statistical methods and reported data in a satisfactory manner. We therefore conclude that the methodology of drug utilization studies needs to be improved.

In order to estimate the burden of mental disorders in a representative Italian pediatric population, an epidemiological study was performed using three administrative databases: a drug prescription, a hospital discharge form, and an outpatient ambulatory visit database. The population target was 1,616,268 children and adolescents under 18 years living in the Lombardy Region, Italy. A youth was defined as a case if during 2008 he/she received at least one psychotropic drug prescription or was hospitalized for a psychiatric disorder (International Classification of Disease codes 290-319), or attended a child neuropsychiatric outpatient unit for a visit and/or a psychological intervention or rehabilitation at least once. Epileptic children were excluded. In all, 63,550 youths (39.3 per 1000; 95%CI 39.1-39.7) were identified as users of health care resources for a putative mental disorder. The prevalence was higher in boys than in girls (47.0 versus 31.3) and the highest value was recorded in children 8 years old (60.2). A total of 59,987 youths (37.1) attended a child and adolescent neuropsychiatry service at least once, 3605 (2.2) were admitted to hospital, and 2761 (1.7) received at least one psychotropic drug prescription, 57% of which did not attend a child neuropsychiatry service. In all, 14,741 youths (23.1% of users) had a disorder that required a high intensity of care (e.g. recurrent prescriptions for drugs and/or ambulatory care). The proportion of youths who received care for mental disorders in the Lombardy Region seems lower than in other countries. However, the fact that many children were prescribed psychotropic drugs without the supervision of a child psychiatrist is a reason for concern.

AIM: To estimate how many asthmatic children underwent spirometry testing in one year in a large Italian region, and evaluate sociodemographic determinants. METHODS: Data were retrieved from the administrative databases that store all pharmacological and diagnostic prescriptions issued to individuals living in the Lombardy Region. The analysis involved prescriptions dispensed to all 6-17 year olds (1,047,241 subjects) during 2008. Youths were identified as asthmatics by a previously validated strategy. Number of subjects having ≥1 spirometry claims was calculated, and factors associated with the probability of undergoing spirometry were evaluated by multivariate analysis. RESULTS: A total of 40,528 (3.9%) asthmatic subjects were identified. Only 30% of them underwent ≥1 spirometry during 2008, with differences between local health units (range 22-45%) and degree of anti-asthmatic use (26-35%). Moreover, in a multivariate analysis, the chance of undergoing spirometry was greater in boys than in girls (OR=2.3). CONCLUSIONS: A low percentage of asthmatic children, especially girls (who are more at risk of developing severe disease in adulthood), underwent spirometry during 1-year period. This highlights a low compliance with guidelines in the monitoring of childhood asthma. Educational intervention is needed in order to encourage use of spirometry in primary care settings.

BACKGROUND: Although anti-asthma medications are amongst those most frequently under or over prescribed it is generally accepted that prescriptions for such agents can be used as a proxy for disease prevalence. The aims of this study were to estimate prevalence and incidence of childhood asthma in a representative Italian area by analysing three years of anti-asthmatic prescriptions and hospitalizations of subjects with chronic or first time treatment, and to underline appropriateness of therapeutic choices. METHODS: The analysis involved prescriptions given to 6-17 year olds between 2003 and 2005 in Italy's Lombardy Region. The youths were classified as potential asthmatics, based on the different degree of drug utilization: occasional, low or high users, and grouped as 'new onset' or 'chronic' cases based on the duration of therapy dispensed. The analysis of prescriptions and hospitalization rate of these groups provided an estimate of the 2005 asthma prevalence and incidence and allowed an estimation of the level of appropriateness of treatments. RESULTS: During 2005, the estimated incidence of potential asthmatics was 0.8% and the estimated prevalence was 3.5%. When viewed retrospectively for two years, records showed that 47% of potential asthmatics received prescriptions also during 2004 and 30% also during 2003. During the three years considered, 7.5%, 2.8%, and 1.5% of high, low, and occasional users, respectively, were hospitalized for asthma. The most important inappropriateness found was the prescription of long acting beta adrenergics as first time treatment. CONCLUSIONS: This study allowed a proxy of asthma incidence, prevalence, and severity. The analyses highlighted a low compliance with the guidelines, suggesting that educational interventions are needed to obtain a more rational management of childhood asthma, especially in subjects starting therapy.

OBJECTIVES: To delineate the safety and tolerability profile of methylphenidate and atomoxetine in children and adolescents with attention deficit hyperactivity disorder (ADHD) monitored for more than 1 year. DESIGN: A cohort study analyzing data from the national ADHD register on patients from the Lombardy Region treated with MPH or atomoxetine. PARTICIPANTS: A total of 229 children (median age 11 years, range 6-17), enrolled in 15 regional centers between June 2007 and May 2010. RESULTS: The prevalence rate of pharmacological treatment for ADHD was 0.23%, whereas the estimated ADHD prevalence in the population was 0.95%. In total, 73.8% of patients had been treated with atomoxetine (10-90 mg daily) or MPH (10-75 mg daily); 22% of patients also received an additional psychotropic drug. Of the treated children, 26.9% discontinued the drug prior to 1 year of treatment, mostly because of adverse effects (28.6%). No new or unexpected adverse events (rate 39.2%) were encountered. Decreased appetite, headache, and unstable mood were the leading events. The most severe events occurred in two boys: one experienced absence seizures for the first time with MPH, the other experienced hallucinations with atomoxetine. Therapy was discontinued in ten male patients (7.7%) because of adverse events. All patients with adverse effects recovered well. CONCLUSIONS: A very low rate of ADHD prevalence was estimated in Italian children compared to that reported in other countries. Although the medications for ADHD are generally well tolerated, with only mild or minor adverse effects in most cases, their rational use can only be guaranteed by disseminating and monitoring evidence-based practices and by monitoring the safety and efficacy of treatments in both the short and long terms with appropriate tools and approaches.

PURPOSE: To compare family paediatricians' and general practitioners' habits on drug prescribing to children. METHODS: Prescriptions reimbursed by the Health Service and dispensed by the retail pharmacies of 15 local health units in the Lombardy Region of Italy during 2005 were analysed. Only family paediatricians and general practitioners who were in charge of children aged 6-13 years were included. RESULTS: During 2005, 239,296 children (43.6% of the selected population) received at least one drug prescription. The prevalence was higher in children treated by general practitioners (44.2 versus 43.4%), in particular in children 13 years old, with a prevalence of 38.7 versus 31.8% in children cared for by general practitioners and family paediatricians respectively. The prevalence of the most prescribed therapeutic classes was similar in the two groups. Some differences were found concerning the antibiotic classes, with family paediatricians prescribing penicillins more frequently and general practitioners prescribing macrolides and cephalosporins more frequently. A total of 542 drugs were prescribed, 78% of which were prescribed by both the family paediatricians and the general practitioners. In all, only four drugs were prescribed by 75% or more physicians. The chance of receiving a drug prescription, adjusted for age, gender and local health unit of residence, was slightly higher in children cared for by general practitioners (OR 1.16; 95%CI 1.14-1.17). CONCLUSIONS: Few differences were found between the prescribing patterns of family paediatricians and those of general practitioners. Differences exist in particular for older children and for some drug classes.

AIMS: To evaluate the intraregional differences in drug prescribing to children and adolescents. METHODS: Prescriptions reimbursed by the National Health System, involving 1543 203 children and adolescents <18 years old and dispensed during 2005 by the retail pharmacies of 15 local health units (LHU) in the Lombardy Region, were analysed. Logistic regression analysis was performed to evaluate the association between drug prescription and age, gender, prescriber, and setting. RESULTS: A total of 747 790 youths (48%) received at least one drug prescription. The prescription prevalence rate was highest in children 1-5 years old (65%), decreased with increasing age to 38% in adolescents, and was slightly higher in boys than in girls. Antibiotics and anti-asthmatics were the most prescribed therapeutic classes. Amoxicillin + clavulanic acid was the most prescribed drug (18% of children; 20% of packages). Large differences were found in the drug prescription prevalence rate between the different LHUs. The rate ranged between 38.4 and 54.8%, and was not correlated to hospitalization rate in the paediatric population. Being 1-5 years old [odds ratio (OR) 4.51, 95% confidence interval (CI) 4.43, 4.58] and living in the eastern part of the region (OR 2.06, 95% CI 1.99, 2.13) were the factors associated with the highest risk of drug exposure. CONCLUSIONS: The results resemble the profiles observed in other Italian contexts, in particular concerning the wide use of antibiotics and anti-asthmatics. However, large differences were found between LHUs, highlighting the need for more detailed investigations on therapeutic needs, drug use, and related variables in different geographic contexts.
