Effect of organizational features on patient satisfaction with care in Italian multiple sclerosis centres.

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.

Migraine and cranial autonomic symptoms in children and adolescents: a clinical study.

The frequency of cranial autonomic symptoms in children affected by primary headaches is uncertain. The aim of our study was to estimate the frequency of symptoms in pediatric headaches and correlate it with main migraine characteristics. A questionnaire investigating the presence of cranial autonomic symptoms was administered to all children with primary headache for 2 years. A total of 230 children with primary headache (105 males, 125 females) were included. Two hundred two children were affected by migraine and 28 (12.2%) by other primary headaches. Cranial autonomic symptoms were significantly complained by migraineurs (55% vs. 17.8%) (P < .001) and by children with higher frequency of migraine attacks (odds ratio = 2.6, confidence interval = 1.4-4.7, P = .001). Our findings show that cranial autonomic symptoms are rather common during pediatric migraine attacks. The association between cranial autonomic symptoms and higher frequency of attacks might suggest the role of the trigeminal-autonomic reflex in migraine pathophysiology.

Clinical and magnetic resonance imaging predictors of disease progression in multiple sclerosis: a nine-year follow-up study.

OBJECTIVE: The objective of this paper is to identify clinical or magnetic resonance imaging (MRI) predictors of long-term clinical progression in a large cohort of multiple sclerosis (MS) patients. METHODS: A total of 241 relapsing-remitting (RR) MS patients were included in a nine-year follow-up (FU) study. The reference MRIs were acquired at baseline (BL) as part of a multicenter, cross-sectional, clinical-MRI study. Volumetric MRI metrics were measured by a fully automated, operator-independent, multi-parametric segmentation method. Clinical progression was evaluated as defined by: conversion from RR to secondary progressive (SP) disease course; progression of Expanded Disability Status Scale (EDSS); achievement and time to reach EDSS 4. RESULTS: We concluded that conversion from RR to SP (OR 0.79; CI 0.7-0.9), progression of EDSS (OR 0.85; CI 0.77-0.93), achievement of EDSS 4 (OR 0.8; CI 0.7-0.9), and time to reach EDSS 4 (HR 0.88; CI 0.82-0.94) were all predicted by BL gray matter (GM) volume and, except for progression of EDSS, by BL EDSS (respectively: (OR 2.88; CI 1.9-4.36), (OR 2.7; CI 1.7-4.2), (HR 3.86; CI 1.94-7.70)). CONCLUSIONS: BL GM volume and EDSS are the best long-term predictors of disease progression in RRMS patients with a relatively long and mild disease.

Natalizumab therapy of multiple sclerosis: recommendations of the Multiple Sclerosis Study Group--Italian Neurological Society.

Three years after the introduction of natalizumab (NA) therapy for the second line treatment of relapsing-remitting multiple sclerosis (MS), Italian MS centers critically reviewed the scientific literature and their own clinical experience. Natalizumab was shown to be highly efficacious in the treatment of MS. However, the risk of progressive multifocal leukoencephalopathy was confirmed and defined better. This article summarizes the MS-SIN Study Group recommendations on the use of NA in MS, with particular reference to the appropriate selection and monitoring of patients as well as to the management of adverse events.

Prevalence of red ear syndrome in juvenile primary headaches.

BACKGROUND: Previous studies have suggested a relationship between 'red ear syndrome' (RES) and pediatric migraine. Aims of this study were (i) to assess the frequency, specificity and sensitivity of RES in a population of pediatric migraineurs and (ii) to establish the pathophysiological mechanisms of RES associated with migraine. METHODS AND RESULTS: A total of 226 children suffering from headache (aged 4-17 years) were enrolled. One hundred and seventy-two (76.4%) were affected by migraine, the remaining 54 (23.6%) by other primary headaches. RES was followed significantly more frequently by migraine (23.3%; p < .0001), and was characterized by high specificity and positive predictive value (96.3 and 95.3%, respectively). According to the univariate statistical analysis, RES showed a statistically significant association with male gender, throbbing quality of the pain, vomiting and phonophobia. It was confirmed by a multivariate stepwise logistic regression model only for the throbbing quality of the pain, vomiting and male gender. CONCLUSIONS: Our study showed that (i) in children, RES is a highly specific sign for migraine. In addition, the evidence of an association of RES with some migraine features partially provoked by the parasympathetic system supports the hypothesis of a shared pathophysiological background (e.g. via the activation of the trigeminal-autonomic reflex).

Three years of experience: the Italian registry and safety data update.

At the end of 2006, a pharmacovigilance program on natalizumab was settled by the Italian Pharmaceutical Agency, and on January 2007, multiple sclerosis patients poorly responding to the immunomodulating therapies or with an aggressive clinical form of disease from onset initiated to be registered and to receive the medication. On February 2010, almost 3,000 cases have been treated with natalizumab. The drop-out rate is 10%. Almost 800 cases received cycles of natalizumab for more than 18 months. One case of PML was reported and other adverse events are similar to those described in phase III studies. The majority of cases remained stable, while in 25% of cases, an improvement of disability was documented.

Multiple sclerosis survival: a population-based study in Sicily.

BACKGROUND AND PURPOSE: There are few population-based surveys on multiple sclerosis (MS) survival. To investigate MS survival in MS patients recruited during surveys conducted in Sicily. METHODS: Multiple sclerosis patients identified during previous surveys were randomly matched to two referent subjects by residence, year of birth, and gender. Living status was obtained by municipality records (end of follow-up June, 30th 2007) and, for the deceased, date and causes of death were searched. Kaplan-Meier plots were used to calculate differences in mortality between MS patients and referent subjects. MS risks for mortality with 95% confidence intervals (CI) were also calculated. RESULTS: We included 194 MS patients and 388 matched persons. Thirty MS patients (15.5%) and 28 referents (7.2%) had died until the end of follow-up. Mean survival from onset of the disease to death was 20.6 years. Mean age at death was 55.5 for MS patients and 64.8 for the referents. Adjusted Hazard Ratios for mortality in MS was 1.81 (95% CI 1.36-2.40). Kaplan-Meier estimates showed a higher mortality amongst patients compared to referent subjects (P < 0.001). CONCLUSIONS: The present study confirms the higher mortality risk in MS patients with no significant gender difference. Causes of death are related to complications of high disability and to increasing age.

The pharmacovigilance program on natalizumab in Italy: 2 years of experience.

At the end of 2006 a country-based surveillance program on natalizumab therapy in multiple sclerosis was settled in Italy by a collaborative effort of the Italian Drug Agency (AIFA) and a group of experts and neurologists appointed by the National Society of Neurology (SIN). After 2 years, 1,818 patients are registered in the database. The majority of cases (88.6%) failed the therapy with beta interferon or glatiramer acetate and had relapses or accumulated disability during immunomodulating treatment, while 11.4% of patients enrolled in the surveillance study were not previously treated with immunomodulating therapies and had a rapidly evolving clinical course. Almost 10% of the patients treated with natalizumab interrupted, for various different reasons, the therapy. Treatment was well tolerated and side effects were similar to those reported in the registrative studies. The majority of treated cases are stable or ameliorated.

An exploration of anger phenomenology in multiple sclerosis.

BACKGROUND AND PURPOSE: Multiple sclerosis (MS) patients are often emotionally disturbed. We investigated anger in these patients in relation to demographic, clinical, and mood characteristics. PATIENTS AND METHODS: About 195 cognitively unimpaired MS patients (150 relapsing-remitting and 45 progressive) were evaluated with the State Trait Anger Expression Inventory, the Chicago Multiscale Depression Inventory, and the State Trait Anxiety Inventory. The patients' anger score distribution was compared with that of the normal Italian population. Correlation coefficients among scale scores were calculated and mean anger scores were compared across different groups of patients by analysis of variance. RESULTS: Of the five different aspects of anger, levels of withheld and controlled Anger were respectively higher and lower than what is expected in the normal population. Although anger was correlated with anxiety and depression, it was largely independent from these mood conditions. Mean anger severity scores were not strongly influenced by individual demographic characteristics and were not higher in more severe patients. CONCLUSIONS: The presence of an altered pattern of anger, unrelated to the clinical severity of MS, suggests that anger is not an emotional reaction to disease stress. An alteration of anger mechanisms might be a direct consequence of the demyelination of the connections among the amygdale, the basal ganglia and the medial prefrontal cortex.

Brain atrophy evolution and lesion load accrual in multiple sclerosis: a 2-year follow-up study.

BACKGROUND: To investigate in a large cohort of patients with multiple sclerosis (MS), lesion load and atrophy evolution, and the relationship between clinical and magnetic resonance imaging (MRI) correlates of disease progression. METHODS: Two hundred and sixty-seven patients with MS were studied at baseline and two years later using the same MRI protocol. Abnormal white matter fraction, normal appearing white matter fraction, global white matter fraction, gray matter fraction and whole brain fraction, T2-hyperintense, and T1-hypointense lesions were measured at both time points. RESULTS: The majority of patients were clinically stable, whereas MRI-derived brain tissue fractions were significantly different after 2 years. The correlation between MRI data at baseline and their variation during the follow-up showed that lower basal gray matter atrophy was significantly related with higher progression of gray matter atrophy during follow-up. The correlation between MRI parameters and disease duration showed that gray matter atrophy rate decreased with increasing disease duration, whereas the rate of white matter atrophy had a constant pattern. Lower basal gray matter atrophy was associated with increased probability of developing gray matter atrophy at follow-up, whereas gray matter atrophy progression over 2 years and new T2 lesion load were risk factors for whole brain atrophy progression. CONCLUSIONS: In MS, brain atrophy occurs even after a relatively short period of time and in patients with limited progression of disability. Short-term brain atrophy progression rates differ across tissue compartments, as gray matter atrophy results more pronounced than white matter atrophy and appears to be a early phenomenon in the MS-related disease progression.

Body mass index does not change before Parkinson's disease onset.

BACKGROUND AND PURPOSE: Previous studies on the association between Parkinson's disease (PD) and body mass index (BMI) have reported conflicting results. We investigated the relationship between PD and BMI by a case-control study. METHODS: PD patients were randomly matched to healthy individuals by sex and age. BMI distribution in cases has been compared with BMI of controls and odd ratios (ORs) with 95% CI were calculated. RESULTS: We included 318 PD patients and 318 controls. We observed no association between PD and BMI. BMI distribution in cases and controls was similar also when we adjusted for diabetes, hypercholesterolemia and the time elapsed between PD onset and the interview (OR = 0.99; CI = 0.94-1.03; P = 0.51). CONCLUSIONS: These results did not confirm the previously reported association between PD and BMI. Population characteristics and methodological issues may partially account for the differences observed between the present study and the others.

Prevalence of Parkinson's disease and other types of parkinsonism in the Aeolian Archipelago, Sicily.

OBJECTIVE: To estimate prevalence of Parkinson's disease (PD) and other types of parkinsonism in the Aeolian Archipelago, Sicily. METHODS: We studied the frequency of PD and other types of parkinsonism in the Aeolian Archipelago (population 13,431). All potential cases were identified from available medical information sources. To ensure the completeness of the case-findings, a screening questionnaire was also mailed to residents aged 40 years and over. Subjects were considered prevalent if they fulfilled the SNES diagnostic criteria for PD, on prevalence day (January 1, 2001). RESULTS: We identified 17 patients with parkinsonism from medical sources, and 4 from mail-survey. Prevalence for all types of parkinsonism was 156.3/100,000 (95% CI 99.4-234.8). Fourteen subjects fulfilled diagnostic criteria for PD giving a crude prevalence of 104.2/100,000 (95% CI 59.4-170.7) and 422.5/100,000 in the population aged 60 years and over. CONCLUSIONS: Prevalence of all types of parkinsonism and PD found in the Aeolian Archipelago is lower than that previously reported in Sicily.

Mortality in multiple sclerosis: a review.

This work was undertaken to evaluate studies on mortality caused by multiple sclerosis (MS), to evaluate if useful inferences can be drawn from survival studies that can be applied to clinical practice. A literature search was carried out to find epidemiological studies on MS prognosis, survival, mortality and causes of death relevant to our aim. The World Health Organization (WHO) reports on worldwide cause-specific mortality were also considered. Studies were evaluated according to the duration of the follow-up study, the year of publication and the methodology used. We evaluated MS survival from a methodological point of view and considered if time trends could be drawn from study results. We conclude that mortality is only slightly higher in MS patients when compared with that in the general population. Mortality is higher particularly for older patients and those with longer disease duration.

Autosomal dominant hereditary spastic paraplegia: report of a large Italian family with R581X spastin mutation.

We describe a large kindred with a typical pure form of autosomal dominant hereditary spastic paraplegia (ADHSP). On the basis of maximum LOD score of 1.94 at theta (max)=0 with marker D2S367, we obtained suggestive evidence for linkage of ADHSP to SPG4 locus. Denaturing high-performance liquid chromatography (DHPLC) and direct sequence analysis allowed us to identify a nonsense mutation (1741* C>T) in exon 17 of the Spastin gene. This transition, carried by all the affected family members and two apparently healthy individuals, lead to truncation of the last 36 amino acids in the C-terminus of the protein. These results confirm the existence of mutation in the SPG4 gene with a reduced penetrance, indicating that other genetic or environmental factors are required to trigger full-blown disease.

Dropped head as an unusual presenting sign of myasthenia gravis.

Prominent or isolated weakness of cervical extensor muscles is a relatively rare clinical sign. Commonly, this is known as "dropped-head syndrome". This abnormal flexion of the head may occur in a variety of neuromuscular diseases and in a few non-neurological disorders as well. The case we describe concerns a 61-year-old woman with dropped-head syndrome as the unique complaint of myasthenia gravis.

Treatment of multiple sclerosis with interferon beta in clinical practice: 2-year follow-up data from the South Italy Mobile MRI Project.

This follow-up study assessed the 2-year clinical and magnetic resonance imaging (MRI) outcomes of patients with multiple sclerosis (MS) originally enrolled in an MRI study conducted at eight centres in south Italy (the South Italy Mobile MRI Project). Of the 597 MS patients recruited at baseline, 391 returned for the follow-up study. Of these, 363 provided 2-year clinical and MRI follow-up data, and 215 were still undergoing treatment with one of four interferon beta regimens: Avonex, 30 mcg intramuscularly once weekly; Betaferon, 250 mcg subcutaneously (sc) every other day; Rebif 22 mcg sc three times weekly (tiw; Rebif 22); or Rebif 44 mcg sc tiw (Rebif 44). Over the 2-year follow-up period, patients receiving the higher dose of Rebif were more likely to remain free from relapses [odds ratio (OR) = 2.23] and from developing both new T2 (OR = 0.15) and new T1 black hole lesions (OR = 0.22), when compared with patients in the Avonex group. Despite some limitations in the trial design, the results from this follow-up study provide helpful clinical and MRI data on the efficacy of interferon beta regimens in MS patients treated in the clinical setting.

APOE epsilon variation in multiple sclerosis susceptibility and disease severity: some answers.

BACKGROUND: Previous studies have examined the role of APOE variation in multiple sclerosis (MS), but have lacked the statistical power to detect modest genetic influences on risk and disease severity. The meta- and pooled analyses presented here utilize the largest collection, to date, of MS cases, controls, and families genotyped for the APOE epsilon polymorphism. METHODS: Studies of MS and APOE were identified by searches of PubMed, Biosis, Web of Science, Cochrane Review, and Embase. When possible, authors were contacted for individual genotype data. Meta-analyses of MS case-control data and family-based analyses were performed to assess the association of APOE epsilon genotype with disease risk. Pooled analyses of MS cases were also performed to assess the influence of APOE epsilon genotype on disease severity. RESULTS: A total of 22 studies (3,299 MS cases and 2,532 controls) were available for meta-analysis. No effect of epsilon2 or epsilon4 status on MS risk was observed (summary OR 1.14, 95% CI 0.96-1.34 and OR 0.89, 95% CI 0.78-1.01). Results obtained from analyses of APOE genotypes in 1,279 MS families were also negative (p = 0.61). Finally, results from pooled analyses of 4,048 MS cases also argue strongly that APOE epsilon status does not distinguish a relapsing-remitting from primary progressive disease course, or influence disease severity, as measured by the Expanded Disability Status Scale and disease duration. CONCLUSION: Overall, these findings do not support a role for APOE in multiple sclerosis, and underscore the importance of using large sample sizes to detect modest genetic effects, particularly in studies of genotype-phenotype relationships.

Cognitive dysfunction in patients with relapsing-remitting multiple sclerosis.

Cognitive dysfunction is considered one of the clinical markers of multiple sclerosis (MS). However, in the literature there are inconsistent reports on the prevalence of cognitive dysfunction, and separate data for the relapsing-remitting (RR) type of the disease are not always presented. In this study, we submitted 461 RRMS patients to a battery of neuropsychological tests to investigate their impairment in various cognitive domains. As a consequence of the exclusion criteria, the sample is not fully representative of the entire population of RRMS patients. In this selected sample, when only the eight scores of a core battery (Mental Deterioration Battery) were considered (with respective cutoffs), it emerged that 31% of the patients were affected by some degree of cognitive deficit. In particular, 15% had mild, 11.2% moderate and 4.8% had severe impairment. Information processing speed was the most frequently impaired area, followed by memory. When two other tests (SDMT and MCST) were added and cognitive domains were considered, it emerged that 39.3% of the patients were impaired in two or more domains. When four subgroups were obtained by means of cluster analysis and then compared, it emerged that information processing speed and memory deficits differentiated the still cognitively unimpaired from the mildly impaired MS patients. Significant associations were found between cognitive and clinical characteristics. However, due to the large sample size, clinically irrelevant relationships may also have emerged. Even with the limitations imposed by the sample selection and the possible underestimation of the prevalence and severity of cognitive dysfunction, these results seem to provide further evidence that information processing speed deficit may be an early and important marker of cognitive impairment in MS patients.
