RESUMO

PURPOSE: This cross-sectional study aimed at comparing the quality of life (Qol), the prevalence of psychiatric diagnosis and pharmacological treatment in 104 candidates to bariatric surgery according to the degree of obesity (class 2 vs. class ≥ 3 obesity). METHODS: All surgical candidates underwent a detailed psychiatric interview based on DSM-5 criteria, including sociodemographic, clinical, psychological and psychiatric data. Participants completed the Binge Eating Scale (BES) and the 12-Item Short Form Health Survey (SF-12). RESULTS: Overall, bariatric candidates reported a significant impairment in the physical (PCS 38.8 [95% CI 36.2-41.5]) and mental (MCS 42.2 [95% CI 40.4-43.9]) components of Qol compared to population norms (p < 0.001 for both). Subjects with class 2 obesity scored significantly lower in the MCS compared to those with class 3 (38.7 (8.1) vs. 43.6 (8.4), p = 0.008). No other statistically significant differences were found between the two groups in terms of sociodemographic and clinical variables. CONCLUSION: These data support the usefulness of Qol assessment in bariatric candidates as a sensible screening parameter, especially in patients with lower BMI, in whom MCS could identify the need for early psychosocial intervention. LEVEL OF EVIDENCE: Level III, case-control analytic study.

RESUMO

The aim was to evaluate the effectiveness of strengthening exercises using the Swiss ball in patients with fibromyalgia through a randomized controlled trial with intention to treat analyses. A total of 60 patients with fibromyalgia met the inclusion criteria and were randomly allocated to either the Swiss ball exercise group (n=30) or a stretching group (n=30). All patients participated in 40-minute training sessions 3 times per week for 12 weeks. Pain (Visual Analogue Scale 0-100); muscle strength (One Repetition Maximum test); health status (Fibromyalgia Impact Questionnaire Revised); quality of life (Short Form-36 questionnaire) were evaluated at baseline, and after 6 and 12 weeks of training. The Swiss ball group showed a statistically significant improvement in VAS (0-100) (p<0.001), SF-36 (p<0.05) and Fibromyalgia Impact Questionnaire (p<0.001) compared with the stretching group. The results of this study proved that the treatment for fibromyalgia with strengthening exercises and the use of the Swiss ball led to improvement of pain, quality of life, muscle strength and decreased the need for medications for this disease compared to stretching exercises, without negative effects.

RESUMO

The development of compact accelerator facilities providing high-brightness beams is one of the most challenging tasks in the field of next-generation compact and cost affordable particle accelerators, to be used in many fields for industrial, medical, and research applications. The ability to shape the beam longitudinal phase space, in particular, plays a key role in achieving high-peak brightness. Here we present a new approach that allows us to tune the longitudinal phase space of a high-brightness beam by means of plasma wakefields. The electron beam passing through the plasma drives large wakefields that are used to manipulate the time-energy correlation of particles along the beam itself. We experimentally demonstrate that such a solution is highly tunable by simply adjusting the density of the plasma and can be used to imprint or remove any correlation onto the beam. This is a fundamental requirement when dealing with largely time-energy correlated beams coming from future plasma accelerators.

RESUMO

Plasma-based technology promises a tremendous reduction in size of accelerators used for research, medical, and industrial applications, making it possible to develop tabletop machines accessible for a broader scientific community. By overcoming current limits of conventional accelerators and pushing particles to larger and larger energies, the availability of strong and tunable focusing optics is mandatory also because plasma-accelerated beams usually have large angular divergences. In this regard, active-plasma lenses represent a compact and affordable tool to generate radially symmetric magnetic fields several orders of magnitude larger than conventional quadrupoles and solenoids. However, it has been recently proved that the focusing can be highly nonlinear and induce a dramatic emittance growth. Here, we present experimental results showing how these nonlinearities can be minimized and lensing improved. These achievements represent a major breakthrough toward the miniaturization of next-generation focusing devices.

RESUMO

BACKGROUND AND PURPOSE: Nabiximols (Sativex® ) is a cannabinoid-based compound used for the treatment of moderate to severe spasticity in multiple sclerosis (MS). The aim of the study was to investigate the effect of the administration of Nabiximols on blood transcriptome profile of patients with MS and to interpret it in the context of pathways and networks. METHODS: Whole-genome expression profiling was performed in whole blood of 33 subjects with MS at baseline and after 4 weeks of drug treatment. Patients were classified as responders (n = 19) and non-responders (n = 14). Pathway and network analyses on genes modulated by the drug were performed, followed by in vitro stimulation of peripheral blood mononuclear cells with pro-inflammatory agents to support the immunomodulatory properties of the drug. RESULTS: Individual effect size was modest; however, we observed a downregulation of several immune-related pathways after 4 weeks of treatment, which was more pronounced when restricting analyses to responders. Interesting hub molecules functionally related to the immune system emerged from network analysis, including NFKB1, FYN, MAP14 and TP53. The immunomodulatory properties of the drug were confirmed through in vitro assays in peripheral blood mononuclear cells collected from patients with MS. CONCLUSIONS: Our findings support the immunomodulatory activity of cannabinoids in patients with MS. Further studies in more specific cell types are needed to refine these results.

RESUMO

BACKGROUND: Several studies have shown an association between 25-hydroxyvitamin D (25[OH]D) levels and multiple sclerosis (MS) susceptibility and/or level of disease activity in patients treated with first line drugs. AIMS: To investigate whether baseline 25[OH]D values could influence disease activity also during treatment with the second-line drug fingolimod (FTY). PATIENTS AND METHODS: We enrolled 176 MS patients who started FTY at the San Raffaele Hospital (OSR) MS center with available 25[OH]D measurement at the time of treatment start. We then prospectively followed them for 2 years with periodic clinical examinations and MRI scans. RESULTS: We found no linear correlation between baseline 25[OH]D levels and annualized relapse rate (ARR) or time to first relapse. However, we observed that patients with serum 25[OH]D ≥ 100 nmol/l showed a lower number of Gd+ and combined unique activity (CUA) lesions at baseline compared to patients with the lowest 25[OH]D levels (less than 50 nmol/l, p value < 0.05). Moreover, they showed fewer CUA lesions at 2-year follow-up also when accounting for baseline level of disease activity (p value < 0.05). CONCLUSIONS: In patients treated with FTY, those with the highest baseline 25(OH)D levels had a significantly lower number of active lesions at baseline; the same effect, even if weaker, was observed also at 2-year follow-up when adjusting for baseline disease activity. Given Vitamin D supplementation safety profile, also if a causal effect has not yet been shown, most of MS patients could probably benefit from 25[OH]D levels above those currently considered to be sufficient.

RESUMO

The aim of the study is the identification of genetic factors that influence the long-term response to interferon-ß (IFNß) (4-year follow-up). We performed a genome-wide association study in 337 IFNß-treated Italian multiple sclerosis patients at the extreme of treatment response, and we meta-analyzed association effects, integrating results with pathway analysis, gene-expression profiling of IFNß-stimulated peripheral blood mononuclear cells from 20 healthy controls (HC) and expression quantitative locus (eQTL) analyses. From meta-analysis, 43 markers were associated at P<10-4, and two of them (rs7298096 and rs4726460) pointed to two genes, NINJ2 and TBXAS1, that were significantly downregulated after IFNß stimulation in HC (P=3.1 × 10-9 and 5.6 × 10-10). We also observed an eQTL effect for the allele associated with favorable treatment response (rs4726460A); moreover, TBXAS1 appeared downregulated upon IFNß administration (ß=-0.39; P=0.02). Finally, we found an enrichment of pathways related to inflammatory processes and presynaptic membrane, the latter with involvement of genes related to glutamatergic system (GRM3 and GRIK2), confirming its potential role in the response to IFNß.

RESUMO

Up to 50% of multiple sclerosis (MS) patients do not respond to interferon-beta (IFN-ß) treatment and determination of response requires lengthy clinical follow-up of up to 2 years. Response predictive genetic markers would significantly improve disease management. We aimed to identify IFN-ß treatment response genetic marker(s) by performing a two-stage genome-wide association study (GWAS). The GWAS was carried out using data from 151 Australian MS patients from the ANZgene/WTCCC2 MS susceptibility GWAS (responder (R)=51, intermediate responders=24 and non-responders (NR)=76). Of the single-nucleotide polymorphisms (SNP) that were validated in an independent group of 479 IFN-ß-treated MS patients from Australia, Spain and Italy (R=273 and NR=206), eight showed evidence of association with treatment response. Among the replicated associations, the strongest was observed for FHIT (Fragile Histidine Triad; combined P-value 6.74 × 10-6) and followed by variants in GAPVD1 (GTPase activating protein and VPS9 domains 1; combined P-value 5.83 × 10-5) and near ZNF697 (combined P-value 8.15 × 10-5).

RESUMO

The sensitivity of lymph node core-needle biopsy under imaging guidance requires validation. We employed power Doppler ultrasonography (PDUS) to select the lymph node most suspected of malignancy and to histologically characterize it through the use of large cutting needle. Institutional review board approval and informed consent were obtained for this randomized clinical trial. In a single center between 1 January 2009 and 31 December 2015, patients with lymph node enlargement suspected for lymphoma were randomly assigned (1:1) to biopsy with either standard surgery or PDUS-guided 16-gauge modified Menghini needle. The primary endpoint was the superiority of sensitivity for the diagnosis of malignancy for core-needle cutting biopsy (CNCB). Secondary endpoints were times to biopsy, complications, and costs. A total of 376 patients were randomized into the two arms and received allocated biopsy. However, four patients undergoing CNCB were excluded for inadequate samples; thus, 372 patients were analyzed. Sensitivity for the detection of malignancy was significantly better for PDUS-guided CNCB [98.8%; 95% confidence interval (CI), 95.9-99.9] than standard biopsy (88.7%; 95% CI, 82.9-93; P < 0.001). For all secondary endpoints, the comparison was significantly disadvantageous for conventional approach. In particular, estimated cost per biopsy performed with standard surgery was 24-fold higher compared with that performed with CNCB. The presence of satellite enlarged reactive and/or necrotic lymph nodes may impair the success of an open surgical biopsy (OSB). PDUS and CNCB with adequate gauge are diagnostic tools that enable effective, safe, fast, and low-cost routine biopsy for patients with suspected lymphoma, avoiding psychological and physical pain of an unnecessary surgical intervention.

RESUMO

BACKGROUND AND PURPOSE: Receiving clear, complete and up-to-date information and having a satisfying relationship with the health professional (HP) are of primary importance for MS patients. Healthcare organization plays a key role in promoting an effective relationship and communication between patients and HPs. The present study aims to explore which care organization and service characteristics provided by Italian MS centres best predict patients' satisfaction with healthcare. METHODS: Eighty-one centres and 707 patients (502 women, mean age 40.5 years, SD 10.2; mean education 12.2 years, SD 3.6; time since diagnosis 5.9 years, SD 1.5) were included in the analysis. The care organization and service provided by each centre were evaluated in comparison with the National Institute for Health and Care Excellence (NICE) guidelines on management of MS. Patients' satisfaction with care was measured using the patient self-assessed questionnaire 'Comunicazione medico-paziente nella Sclerosi Multipla, revised' section 2 (COSM-R section 2). RESULTS: The clinical characteristics of patients significantly affected their satisfaction. A multivariate regression model showed that higher patients' satisfaction (COSM-R score) was inversely associated with hospital size (number of patients under care) (ß = -0.21, 95% confidence interval -0.35; -0.07) and directly associated with psychological interventions (ß = 2.44, 95% confidence interval 0.29; 4.59). CONCLUSIONS: Multiple sclerosis patients from larger hospitals are less satisfied with the information received and the relationship with HPs. Building an individualized relationship between patients and HPs and tailoring the communication of information improve patients' satisfaction. Such a goal is probably less likely to be accomplished in larger centres with many incoming patients. Moreover, when the centres also provide structured psychological interventions, the patients are more satisfied.

RESUMO

OBJECTIVES: Since its introduction, MRI had a major impact on the early and more precise diagnosis of multiple sclerosis (MS), and the 2010 diagnostic criteria even allow a diagnosis to be made just after a single attack if stringent MRI criteria are met. Several other clinical and paraclinical markers have been reported to be associated with an increased risk of MS independently of MRI in patients with clinically isolated syndromes (CIS), but the incremental usefulness of adding them to the current criteria has not been evaluated. In this study, we determined whether multiple biomarkers improved the prediction of MS in patients with CIS in a real-world clinical practice. MATERIALS AND METHODS: This was a retrospective study involving patients with CIS admitted to our department between 2000 and 2013. We evaluated baseline clinical, MRI, neurophysiological, and cerebrospinal fluid (CSF) data. RESULTS: During follow-up (median, 7.2 years), 127 of 243 participants (mean age, 31.6 years) developed MS. Cox proportional-hazards models adjusted for established MRI criteria, age at onset, number of T1 lesions, and presence of CSF oligoclonal bands significantly predicted the risk of developing MS at 2 and 5 years. The use of multiple biomarkers led to 29% net reclassification improvement at 2 years (P<.001) and 30% at 5 years (P<.001). CONCLUSIONS: The simultaneous addition of several biomarkers significantly improved the risk stratification for MS in patients with CIS beyond that of a model based only on established MRI criteria.

RESUMO

Besides the impact of disease per se, the use of immunomodulatory therapies in adolescents with relapsing-remitting multiple sclerosis (RRMS) may have an effect on quality of life (QL). The FUTURE (Quality of liFe in adolescent sUbjecTs affected by mUltiple sclerosis treated with immunomodulatoRy agEnt using self-injecting device) study was designed to evaluate the changes in QL of Italian adolescents with RRMS receiving treatment with IFN-ß1a (Rebif; 22 µg), administered subcutaneously three times weekly using the RebiSmart™ electronic autoinjection device over a 52-week period. Fifty adolescents with RRMS were enrolled and 40 completed the study. Changes from baseline to end of treatment (EoT) in adolescent self-reported and parent-reported QL were assessed using the Pediatric Quality of Life Inventory Multidimensional Fatigue Scale (PedsQL), which has been validated for use in pediatric MS and for which an Italian version is available. The adolescent self-reported total PedsQL4.0 score and all of its subscales tended to increase from baseline to EoT, the only exception being "Emotional functioning." In parent-reported measures, the total PedsQL4.0 score increased significantly from baseline to EoT (+ 5.27 points, p = 0.041). Significant increases were also evident for parent-reported "Psychosocial health summary score" (+ 5.90 points; p = 0.015) and "School functioning" (+ 7.84 points; p = 0.029). Our results indicate that adolescents with RRMS using the electronic injection device RebiSmart™ for self-administration of Rebif® can experience long-term improvements in QL.

RESUMO

The impact of multiple sclerosis (MS) diagnosis on newly diagnosed individuals remains so far little explored. Our aim is to outline affective, personality and quality of life (QoL) correlates of MS patients shortly after MS diagnosis. Thirty-eight (22 F and 16 M) newly-diagnosed MS patients (mean interval from diagnosis communication 4.7 ± 3.8 months, range 1-12 months) underwent the Montgomery-Åsberg Depression Rating Scale and a comprehensive psychological evaluation: Beck Depression Inventory-II, State-Trait Anxiety Inventory, Psychophysiological Questionnaire-Revised, Fear Survey Schedule, Maudsley Obsessional-Compulsive Questionnaire, Impact of Event Scale-Revised, Personal Meaning Questionnaire, Problem Solving Inventory and Multiple Sclerosis Quality of Life-54. The Expanded Disability Status Scale was assessed during the neurological examination. Depressive symptomatology, only partially related to disability, was observed in approximately 40% of patients. The prevalent approach to MS diagnosis was one of avoidance in 65.8% of cases. QoL reductions in self-perception and psychological well-being emerged, together with a peculiar perception of change in health that was not related to neurological disability. With regard to personality assessment, depressive personal meaning organization correlates inversely with important QoL measures. Newly-diagnosed patients go through a complex network of psychological changes still in the initial phases immediately after diagnosis. A thorough understanding of these adjusting aspects by the neurologist could be crucial in improving patients' QoL, participation in relevant disease decisions and adherence to pharmacological therapy.

RESUMO

OBJECTIVE: To assess the long-term benefit-risk profile of repeated courses of rituximab in Caucasian patients affected by neuromyelitis optica (NMO) and related disorders, in everyday clinical practice. METHODS: This is a prospective observational study performed at San Raffaele Hospital, Milan, Italy. From February 2006, we recruited 21 patients affected by NMO and NMO spectrum of disorders (NMOSD) whom underwent at least one cycle of intravenous (i.v.) rituximab and then were followed for at least 2 years. RESULTS: At a mean follow-up time of 48 months, we observed a significant reduction of the annualized relapse rate (ARR), from 2.0 to 0.16 (p < 0.01); and of the median Expanded Disability Status Scale (EDSS), from 5.5 to 4.0 (p < 0.013). There were 12 patients (57%) who remained disease free during the follow-up period. Five patients (24%) reported mild hematological adverse events. Serious infectious adverse events were reported by another four patients: These were all wheelchair bound at the beginning of their rituximab treatment. CONCLUSIONS: A fixed treatment scheme of rituximab, with re-treatment every 6 months, was efficacious for NMO and NMOSD, with a good safety profile; however, to obtain an even better benefit-risk ratio, close monitoring of CD19(+) B cells should be performed before the re-treatment of patients with high-level disability, concomitant leukopenia and hypogammaglobulinemia.

RESUMO

Inflammatory bowel disease consists of multifactorial diseases whose common manifestation is inflammation of the gastrointestinal tract and their pathogenesis remains unknown. This study aimed to analyse the gene polymorphisms in Brazilian patients with inflammatory bowel disease. A total of 101 patients diagnosed with inflammatory bowel disease were analysed for the tumour necrosis factor-alpha (-308 G/A; rs1800629) and interleukin-10 (-1082 G/A; rs1800896) gene polymorphisms. Genotyping was performed through polymerase chain reaction-sequence-specific primer, then fractionated on 2% agarose gel and visualized after staining by ethidium bromide. The anatomic-clinical form of Crohn's disease (CD) predominant was the inflammatory (32.75%), followed by fistulizing (29.31%) and 27.58% stricturing. As control group, a total of 136 healthy subjects, from the same geographical region, were enrolled. The statistical analyses were performed using R program. The frequency of the A allele at tumour necrosis factor-alpha was high in ulcerative colitis (UC) patients (51%) than in controls (22%; P > 0.01). No statistical difference was found with the genotypic and allelic frequencies of CD patients compared to controls (P = 0.54). The polymorphism -1082G/A of interleukin-10 was not statistical different between the diseases compared to controls. Tumour necrosis factor-alpha (TNF-α) (-308G/A) is associated with UC onset, suggesting that the presence of -308A allele could confer a relative risk of 3.62 more to develop UC in general population. Further studies, increasing the number of individuals, should be performed to ratify the role of TNF-α in the inflammatory bowel disease pathogenesis.

RESUMO

Though recent progress in multiple sclerosis (MS) treatment is remarkable, numerous unmet needs remain to be addressed often inducing patients to look for complementary and alternative medicines (CAM), especially herbal remedies (HR). HR use, scarcely investigated in MS, may cause adverse reactions (AR) and interfere with conventional treatment. We performed a survey aimed at evaluating use and attitudes towards HR and factor associated to HR use. Other CAM use and attitudes have been investigated as well. Multiple-choice questionnaires were distributed to MS out patients attending 14 Italian referral Centers. Multivariable logistic regression was used to identify HR use determinants. Present/past HR use for either MS or other diseases was reported in 35.6 % of 2419 cases (95 % CI 36.0-40.0 %). CAM use was reported in 42.5 % of cases. Independent predictors of HR use were represented by higher education, geographic area, dissatisfaction with conventional treatment of diseases other than MS and benefit perception from CAM use. Both HR and CAM use were not always disclosed to the healthcare professional. In conclusion, HR and other CAM appear to be popular among MS patients. The involvement of the healthcare professionals appears to be scarce with potential risk of AR or interference with conventional treatments.

RESUMO

BACKGROUND: The role of genetic factors in influencing the clinical expression of multiple sclerosis (MS) is unclear. OBJECTIVE: The objective of this paper is to identify genes, pathways and networks implicated in age at onset (AAO) and severity, measured using the Multiple Sclerosis Severity Score (MSSS), of primary-progressive MS (PPMS). METHODS: We conducted a genome-wide association study (GWAS) of 470 PPMS patients of Italian origin:. Allelic association of 296,589 SNPs with AAO and MSSS was calculated. Pathway and network analyses were also conducted using different tools. RESULTS: No single association signal exceeded genome-wide significance in AAO and MSSS analyses. Nominally associated genes to AAO and MSSS were enriched in both traits for 10 pathways, including: "oxidative phosphorylation" (FDRAAO=9*10(-4); FDRMSSS=3.0*10(-2)), "citrate (TCA) cycle" (FDRAAO=1.6*10(-2); FDRMSSS=3.2*10(-3)), and "B cell receptor signaling" (FDRAAO=3.1*10(-2); FDRMSSS=2.2*10(-3)). In addition, an enrichment of "chemokine signaling pathway" (FDR=9*10(-4)) for AAO and of "leukocyte transendothelial migration" (FDR=2.4*10(-3)) for MSSS trait was observed, among others. Network analysis revealed that p53 and CREB1 were central hubs for AAO and MSSS traits, respectively. CONCLUSIONS: Despite the fact that no major effect signals emerged in the present GWAS, our data suggest that genetic variants acting in the context of oxidative stress and immune dysfunction could modulate the onset and severity of PPMS.

RESUMO

BACKGROUND AND PURPOSE: The Rio score (RS) and the modified Rio score (MRS) are two scoring systems that can identify the early predictive factors of disability progression in relapsing-remitting multiple sclerosis (RRMS) patients treated with interferon-ß (IFN-ß). The objective of the study was to validate the usefulness of the RS and MRS in a large cohort of multiple sclerosis patients treated with IFN-ß in daily clinical practice. METHODS: The analysis included a cohort of RRMS patients treated with different formulations of IFN-ß for at least 1 year. The RS and MRS were used to classify the patients after 1 year of treatment. Multivariate analysis was performed to identify predictive variables of suboptimal response at 5 years, defined as Expanded Disability Status Scale confirmed progression or switching to a second-line therapy. RESULTS: Sixty-nine of 416 included patients were considered as suboptimal responders at 5-year evaluation. The possible score range was 0-3. A higher risk of suboptimal response was found for RS and MRS in the presence of ≥2 scores (hazard ratio 3.0, P = 0.002, and hazard ratio 5.0, P < 0.0001, respectively). CONCLUSIONS: Our study confirmed, in a daily clinical setting, that MRS had a better specificity and accuracy than RS in identifying the patients who will have a poor response to long-term IFN-ß treatment.

RESUMO

PURPOSE: The aim of our study was to investigate the relationship between bone mineral density (BMD), vitamin D, and electrolyte blood values in patients with spina bifida, to find a possible therapeutic regimen and an intervention to reduce the risk of fractures in this population. METHODS: BMD values were measured in 49 patients (32 females, 17 males; aged 14.1 ± 3.86 years; range 5-20 years) using dual-energy X-ray absorptiometry (DEXA) and were analyzed based on sex, the level of spinal involvement, vitamin D, and electrolyte values, physical activity, body mass index (BMI), and ambulatory status [patients were divided into three subgroups: full-time wheelchair (FTWC), limited ambulator (LA), and full-time ambulator (FTA)]. These data were analyzed considering sex-, age-, and BMD-matched values and compared with those of normal population. RESULTS: BMD was significantly lower in these patients compared with that in the general healthy population (Z-score: -1.2 ± 1.8); in particular, females had Z-score values significantly lower that of the males (Z-score: -2.43 ± 2.02; P < 0.0004). In FTWC subgroup, Z-score was lower than that of the other two subgroups (P < 0.009). Vitamin D values were significantly lower compared with those in the general healthy population (vitamin D spina bifida group: 14.6 ± 8.7 mg/dL; normal subjects: 35 ± 9.8 mg/dL; P < 0.001). Subjects with spina bifida showed hypophosphatemia (<3 mg/dL) because of the lower levels of vitamin D (3.1 ± 0.9 mg/dL; P < 0.001). CONCLUSIONS: Spina bifida patients showed lower BMD, vitamin D, and electrolyte values than the healthy population; hence, they have an increase risk of developing pathological fractures. Vitamin D supplementation for a longer time period could reduce this risk.

RESUMO

BACKGROUND: The SIMS-Trial showed that the 'Sapere Migliora' information aid (IA) for newly diagnosed people with multiple sclerosis (PwMS) effectively improved patient knowledge and satisfaction with care. OBJECTIVES: The objectives of this paper are to assess the effectiveness of the IA in clinical practice and to compare the whole IA with the take-home booklet/website component alone. METHODS: After updating the IA and replacing the CD with a website, a prospective, open-label non-randomised controlled trial compared the whole IA (group A, five SIMS-Trial centres) to take-home (group B, 16 centres). One month after the intervention, participants completed the MS Knowledge Questionnaire (MSKQ), care satisfaction questionnaire (COSM-R) (primary study outcomes), Hospital and Anxiety Depression Scale, and ad hoc questionnaire appraising the IA. RESULTS: We enrolled 159 newly diagnosed PwMS (May 2012-March 2013). Drop-outs were four of 77 (5%, group A) and 11/82 (13%, group B). Primary endpoint (highest tertile both for MSKQ and COSM-R section 2 scores) was achieved by 38/77 (49%) group A and 33/82 (40%) group B (p = 0.25). Attainment of secondary outcomes was also similar between groups. CONCLUSIONS: This study shows that the entire IA is not superior to the booklet/website alone, and that both are comparable in efficacy to the intervention arm of the SIMS-Trial. TRIAL REGISTRATION NUMBER: ISRCTN78940214.
