Visceral and subcutaneous adipose tissue as markers of local and systemic inflammation: a comparison between celiac and obese patients using MRI.

BACKGROUND: Celiac disease (CD) is a systemic inflammatory disease, which primarily affects the gastrointestinal tract. It has been recently demonstrated that adipose-tissue infiltration by proinflammatory immune cells causes a chronic low-grade inflammation in obese patients. Magnetic resonance imaging (MRI) has already proved to be useful in evaluation of inflammatory states. The aim of the present study was to determine whether alterations of visceral and subcutaneous adipose tissue, identified with MRI, could serve as markers of local and systemic inflammation in patients with CD. METHODS: A pilot study was conducted comparing alterations in visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) in CD patients vs obese patients and healthy controls. Fifty patients were enrolled and assigned to one of the following groups: Group A: 11 active CD patients; Group B: 11 CD patients in remission; Group C: 16 obese patients; Group D: 12 healthy controls. A 3-T MRI unit was used and T2-weighted TSE images of VAT and SAT were obtained in specific regions of interest. Serum cytokine concentrations (TNF-α, IL-6, adiponectin, leptin, IL-2, IFN-γ) were determined. RESULTS: There was a significant difference in VAT T2 relaxation time between Group A and B (p < 0.001), A and D (p < 0.01), B and C (p < 0.001). There was a statistically significant difference in SAT T2 relaxation time between Group A and B (p < 0.001), A and C (p < 0.05), A and D (p < 0.001), B and C (p < 0.01). In addition, VAT/SAT T2 relaxation time ratio showed a statistically significant difference between Group A and C (p < 0.05) and between Group B and C (p < 0.01). Only TNF-α and IL-6 significantly correlated with both VAT and VAT/SAT ratio in active CD. CONCLUSIONS: MRI showed similar increased visceral inflammatory signals in patients with active CD and obese patients. However, subcutaneous inflammatory signals were higher in active CD than in all the other groups. These data show that there is a systemic inflammatory state in active CD, whereas chronic inflammation appears confined to VAT in obesity. These data were only partially confirmed by serological cytokine profiles, which showed less specificity than MRI.

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.

Emerging issues on selection criteria of levodopa carbidopa infusion therapy: considerations on outcome of 28 consecutive patients.

Many studies confirmed the efficacy and safety of continuous infusion of intrajejunal levodopa/carbidopa gel (CIILG) for advanced Parkinson's disease (PD). Although this treatment is widely used, definite inclusion/exclusion criteria do not exist. In this prospective open-label study, we evaluated the long-term outcome in 28 consecutive patients and sought to detect any predictive factor to identify the best candidates for CIILG therapy. The assessment was carried out routinely at baseline, after 6 months and every year with UPDRS III-IV, FOG Questionnaire, non-motor symptoms scale, PD questionnaire (PDQ-8), cognitive and psychiatric status evaluation (MMSE, FAB, NPI) and caregiver's quality of life. 17/28 patients reached the 24-month follow-up. A statistically significant beneficial effect was shown on motor complications in short- and long-term follow-up, also on axial symptoms like gait disturbances. A concomitant improvement in PDQ8 score was observed, with a parallel mild amelioration, but not significant, on Caregivers QoL. When classified according to their outcome on QoL, the only predictive positive factor was less severe at Neuropsychiatric Inventory (NPI) score at baseline. Considering the improvement in motor scores (duration of "off" period), the more advanced age was associated with a poorer outcome. Our results confirmed a sustained efficacy and safety in long-term follow-up and suggest that younger age at operation and absence or mild presence of psychiatric/behavioural symptoms could be considered valid predicting factors in selecting the best candidates for this efficacious therapy.

Endovascular treatment of CCSVI in patients with multiple sclerosis: clinical outcome of 462 cases.

Although it is still debated whether chronic cerebro-spinal venous insufficiency (CCSVI) plays a role in multiple sclerosis (MS) development, many patients underwent endovascular treatment (ET) of CCSVI. The objective of the study is to evaluate the outcome and safety of ET in Italian MS patients. Italian MS centers that are part of the Italian MS Study Group were all invited to participate to this retrospective study. A structured questionnaire was used to collect detailed clinical data before and after the ET. Data from 462 patients were collected in 33 centers. ET consisted of balloon dilatation (93 % of cases) or stent application. The mean follow-up duration after ET was 31 weeks. Mean EDSS remained unchanged after ET (5.2 vs. 4.9), 144 relapses occurred in 98/462 cases (21 %), mainly in RR-MS patients. Fifteen severe adverse events were recorded in 3.2 % of cases. Given the risk of severe adverse events and the lack of objective beneficial effects, our findings confirm that at present ET should not be recommended to patients with MS.

Autologous haematopoietic stem cell transplantation with an intermediate intensity conditioning regimen in multiple sclerosis: the Italian multi-centre experience.

BACKGROUND: Over recent years numerous patients with severe forms of multiple sclerosis (MS) refractory to conventional therapies have been treated with intense immunosuppression followed by autologous haematopoietic stem cell transplantation (AHSCT). The clinical outcome and the toxicity of AHSCT can be diverse, depending on the various types of conditioning protocols and on the disease phase. OBJECTIVES: To report the Italian experience on all the consecutive patients with MS treated with AHSCT with an intermediate intensity conditioning regimen, named BEAM/ATG, in the period from 1996 to 2008. METHODS: Clinical and magnetic resonance imaging outcomes of 74 patients were collected after a median follow-up period of 48.3 (range = 0.8-126) months. RESULTS: Two patients (2.7%) died from transplant-related causes. After 5 years, 66% of patients remained stable or improved. Among patients with a follow-up longer than 1 year, eight out of 25 subjects with a relapsing-remitting course (31%) had a 6-12 months confirmed Expanded Disability Status Scale improvement > 1 point after AHSCT as compared with one out of 36 (3%) patients with a secondary progressive disease course (p = 0.009). Among the 18 cases with a follow-up longer than 7 years, eight (44%) remained stable or had a sustained improvement while 10 (56%), after an initial period of stabilization or improvement with median duration of 3.5 years, showed a slow disability progression. CONCLUSIONS: This study shows that AHSCT with a BEAM/ATG conditioning regimen has a sustained effect in suppressing disease progression in aggressive MS cases unresponsive to conventional therapies. It can also cause a sustained clinical improvement, especially if treated subjects are still in the relapsing-remitting phase of the disease.

Effect of the disclosure of MS diagnosis on anxiety, mood and quality of life of patients: a prospective study.

BACKGROUND: In the light of the new diagnostic criteria for multiple sclerosis (MS) and currently available early treatment, this study aimed to explore whether, and to what extent, disclosure of the diagnosis of MS or clinically isolated syndrome (CIS) affects patients' anxiety, mood and quality of life (QoL). METHODS: Eligible participants were all patients referred for the first time to the Neurological Unit who had manifested symptoms suggestive of MS for no more than 6 months. All patients were evaluated for (i) QoL (SEIQoL and MS-QoL54), (ii) Anxiety (STAI) and Depression (CMDI) on study inclusion (T0), 30 days after diagnosis disclosure (T30), and after 1 (T1y) and 2 (T2y) years' follow-up. RESULTS: Two hundred and twenty-nine patients were enrolled; 93 of these were unaware of their diagnosis. Patients who already knew their diagnosis (100 with CIS and 22 with MS) were excluded from the main analyses and used to perform control analyses. At the end of the screening, an MS diagnosis was disclosed to 18 of the 93 patients, whereas a CIS diagnosis was disclosed to 62 patients (12 patients received a diagnosis other than MS or CIS). Thirty days after diagnosis disclosure, irrespective of the diagnosis disclosed, both QoL and Anxiety and Depression were significantly rated as better compared to the start of screening, (p(s) < 0.03), and this improvement remained stable over the two annual follow-ups. However, as suggested by a significant 'Time' × 'Diagnosis' interaction with regard to both QoL and Anxiety and Depression (p(s) < 0.02), the effect of the disclosure in the short term differed depending on CIS or MS diagnosis. Specifically, on MSQoL, which is a health-related QoL scale, we found a statically significant improvement, immediately after the diagnosis disclosure, in both the MS and CIS groups (p(s) < 0.01). Differently, on SEIQoL, which is a non health-related QoL measure, and on the anxiety scale, we observed a statistically significant improvement only in the group which received a MS diagnosis (p(s) < 0.03). CONCLUSIONS: This first prospective study provides objective data showing that early disclosure of MS diagnosis improves both the patient's QoL and psychological well-being. In addition, the results seem to suggest that CIS disclosure does not lead to the same favourable effects.

Quality of life, depression and fatigue in mildly disabled patients with relapsing-remitting multiple sclerosis receiving subcutaneous interferon beta-1a: 3-year results from the COGIMUS (COGnitive Impairment in MUltiple Sclerosis) study.

BACKGROUND: The precise relationships among quality of life, depression, fatigue and cognitive impairment in multiple sclerosis (MS) are complex and poorly understood. OBJECTIVE: To assess the effects of subcutaneous interferon beta-1a on quality of life, depression and fatigue over 3 years in the COGIMUS study, and to examine the relationship between these outcomes and baseline cognitive status. METHODS: COGIMUS was an observational 3-year trial assessing cognitive function in 459 patients with relapsing-remitting MS treated with subcutaneous interferon beta-1a. RESULTS: In total, 331 patients completed the study (168 received interferon beta-1a, 44 µg subcutaneously three times weekly, and 163 received interferon beta-1a, 22 µg subcutaneously three times weekly). Mean MS Quality of Life-54 (MSQoL-54) composite scores did not change over time. There were no significant differences between groups in MSQoL-54 composite scores when patients were grouped by treatment dose and baseline cognitive status. Mean (standard deviation) Hamilton Depression Rating Scale score decreased from 6.8 (4.9) at baseline to 5.8 (5.9) at year 3. Mean total Fatigue Impact Scale scores were low (<30) at all time points. CONCLUSION: Quality of life, depression and fatigue remained largely stable over 3 years; no effects of treatment dose or baseline cognitive status were found.

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.

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.

Nuclear fluorescence serum reactivity on monkey oesophagus: a new antibody for the follow-up of coeliac disease?

We have identified previously a nuclear fluorescence reactivity (NFR) pattern on monkey oesophagus sections exposed to coeliac disease (CD) patients' sera positive for anti-endomysium antibodies (EMA). The aim of the present work was to characterize the NFR, study the time-course of NFR-positive results in relation to gluten withdrawal and evaluate the potential role of NFR in the follow-up of CD. Twenty untreated, 87 treated CD patients and 15 healthy controls were recruited and followed for 12 months. Their sera were incubated on monkey oesophagus sections to evaluate the presence of NFR by indirect immunofluorescence analysis. Duodenal mucosa samples from treated CD patients were challenged with gliadin peptides, and thus the occurrence of NFR in culture supernatants was assessed. The NFR immunoglobulins (Igs) reactivity with the nuclear extract of a human intestinal cell line was investigated. Serum NFR was present in all untreated CD patients, persisted up to 151 ± 37 days from gluten withdrawal and reappeared in treated CD patients under dietary transgressions. Serum NFR was also detected in two healthy controls. In culture supernatants of coeliac intestinal mucosa challenged with gliadin peptides, NFR appeared before EMA. The Igs responsible for NFR were identified as belonging to the IgA2 subclass. The NFR resulted differently from EMA and anti-nuclear antibodies, but reacted with two nuclear antigens of 65 and 49 kDa. A new autoantibody, named NFR related to CD, was described. Furthermore, NFR detection might become a valuable tool in monitoring adherence to a gluten-free diet and identifying slight dietary transgressions.

Effects of immunomodulatory treatment with subcutaneous interferon beta-1a on cognitive decline in mildly disabled patients with relapsing-remitting multiple sclerosis.

The objective of this study was to assess the effects of subcutaneous (sc) interferon beta-1a (IFNbeta-1a) on cognition in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS). Patients aged 18-50 years with RRMS (McDonald criteria; Expanded Disability Status Scale score

The interleukin-1 cluster gene region is associated with multiple sclerosis in an Italian Caucasian population.

BACKGROUND: Polymorphisms of the interleukin-1 (IL-1) gene family have been proposed as potential variants for different diseases including multiple sclerosis (MS). With respect to MS, IL-1 beta (-511 C/T; rs16944), IL-1 beta (+3954 C/T; rs1143634), IL-1 alpha (-889 C/T; rs1800587), IL-1 alpha (+4845 G/T; rs17561), and the variable number of tandem repeats in intron 2 of the IL-1 receptor antagonist (IL-1RN) gene polymorphisms have been studied in different ethnic groups, leading to conflicting results. METHODS: This study investigates the association between IL-1 genes and MS by means of 70 markers spanning the 1.1 Mb region where the IL-1 genes map and exploring both the linkage disequilibrium (LD) and the haplotype structure in a case-control design including 410 subjects (160 patients and 250 controls). RESULTS: From allelic/genotypic tests, significant association was found for several polymorphisms including the IL-1 beta (-511 C/T) variant (P-adjusted = 4.5 x 10(-4)) and some polymorphisms around the IL-1RN gene. The 'block-step' pattern obtained from both the LD map and pairwise analysis identifies four LD regions. Region 1 showed a significant association with MS for the global test (P < 0.0001) and haplotypes containing the IL-1 beta (-511 C/T) variant still demonstrate highly significant association with disease (P-value range: 9.9 x 10(-5) to 0.02). CONCLUSIONS: Our findings support the existence of a causative variant for MS within this candidate region in a representative Italian Caucasian population and, in particular, the role of the IL-1 beta (-511 C/T) variant warrants further investigation.

Dynamics of malaria vector indices in two vegetation zones within North Eastern Adamawa State, Nigeria.

Studies profiling community and zonal malaria entomological risk indices are required to identify high risk areas where targeted control resources are most needed or likely to have the greatest impact on reducing risk of malaria infection. This study presents a first report on malaria vector risk indices in two vegetation zones within Adamawa state, Nigeria. Endophilic mosquitoes were collected for one year in selected communities in the Guinea and Sudan savanna zones within the State. Plasmodium falciparum Sporozoite and human blood meal ELISA assays were carried out on the female Anopheles mosquitoes collected. Sibling species composition of the An. gambiae complex were determined using PCR assays. Mean numbers of mosquitoes in the Guinea savanna communities were significantly (t = 7.73, DF = 11, p < 0.001) higher than the Sudan. Man-biting rates (F = 2.76, p = 0.13) of Anopheles mosquitoes were higher in the Guinea but not significantly different from Sudan savanna. Sporozoite rates of mosquitoes within the Guinea savanna were 2.7 times higher than the Sudan. The predominant Anopheles coluzzii species encountered in the state had higher overall human blood indices (0.63) and sporozoite rates (6.9%) compared to An. gambiae (0.39, 1.9%) and An. arabiensis (0.58, 2.3%) respectively. Overall annual human blood indices (0.59) of mosquitoes in Adamawa were lower compared to reports from other States. Prevalence and higher transmission risks indices of endophilic An. coluzzii mosquitoes reveal the need for LLIN and management of relatively permanent An. coluzzii breeding sites in the State. Widespread cattle rearing lifestyle and lower human blood indices of mosquitoes in the study area suggest the need to investigate cattle blood indices of the mosquitoes in the state. Higher entomological risk indices in the Guinea Savanna zone provide baseline information for prioritization of malaria vector control supplies within the State.

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.

Antitissue transglutaminase antibodies in acute coronary syndrome: an alert signal of myocardial tissue lesion?

BACKGROUND AND AIM: Antitransglutaminase, previously considered identical to antiendomysial in coeliac sprue (CS), have been reported in end-stage heart failure. To clarify the above-mentioned data, we evaluated these antibodies in a cohort of cardiological patients with respect to troponin I, creatine kinase (CK), MB fraction creatine kinase (CK-MB mass) and myoglobin. METHODS: Forty-one patients with acute coronary syndrome (ACS), 39 with dilated cardiomyopathy (DCM), 45 with CS and 58 blood donors (BDs) were evaluated. Antitransglutaminase and antiendomysial antibodies were tested in serum of the patients being studied. RESULTS: High-positive antitransglutaminase values were found in CS, whilst low-positive values were also found in ACS and DCM. In patients at the second ACS, antibody levels were higher than in those at the first cardiac event. In patients with infarct Q, antitransglutaminase were higher than those in infarct non-Q, in which antibody levels were higher than those in unstable angina. A correlation between antitransglutaminase and troponin I, CK, CK-MB mass and myoglobin was found. Finally, antibody levels rose to reach a peak at 30 days from the cardiac event, whereas after further 150 days, approached the values of BDs. Antiendomysial were detectable only in CS. CONCLUSIONS: Data highlight that antitransglutaminase can occur in cardiological patients, and that these antibodies are related to the severity/extent of the myocardial tissue lesion. This feature suggests a loss of specificity for antitransglutaminase in CS. Furthermore, the possibility of employing these antibodies in the long-term follow-up of ACS, could become an object of interesting discussion.

Renal Doppler Resistance Indices in Kidney Transplant Recipients With Proteinuria.

BACKGROUND: The onset of proteinuria in renal transplant recipients may be associated with an increased risk of allograft failure. Little is known about the relationships between factors influencing proteinuria and the Doppler ultrasound (DU) intrarenal resistive index (RI) and pulsatility index (PI) among donor recipients with proteinuria <1000 mg/24 h. METHODS: We assessed correlations between the DU RI and PI and protein content in 93 selected renal transplant recipients: 62 patients with proteinuria 100 to 299 mg/24 h, 16 patients with proteinuria 300 to 499 mg/24 h, and 15 patients with proteinuria 500 to 999 mg/24 h. All patients underwent transplantation in a single center and were monitored by DU for at least 28 months post-transplantation. RESULTS: The DU RI values of the proteinuria 100 to 299 mg/24 h, 300 to 499 mg/24 h, and 500 to 999 mg/24 h groups were 0.67 ± 0.05; 0.65 ± 0.04, and 0.64 ± 0.07, respectively, and the PI values were 1.21 ± 0.20, 1.10 ± 0.14, and 1.15 ± 0.22, respectively. Multivariate logistic regression analysis revealed a correlation between group 100 to 299 mg/24 h and RI values, serum creatinine, living donor (R2 = 19.6%, P = .05); group 300 to 499 mg/24 h and the RI, PI values, cadaver donor (R2 = 17.5%, P = .001); and group 500 to 999 mg/24 h and the RI, PI values, serum creatinine, graft survival (R2 = 15.4%, P = .005). CONCLUSIONS: Among donor recipients with proteinuria <1000 mg/24 h, DU RI values were <0.72 and PI values were <1.41 and correlations were revealed between the incidence of proteinuria and factors such as the RI, PI, and serum creatinine level.

Percutaneous endobiliary radiofrequency ablation for refractory benign hepaticojejunostomy and biliary strictures.

PURPOSE: The objective of this study was to determine the safety and efficacy of percutaneous endobiliary radiofrequency ablation (ERFA) and balloon dilation for the treatment of hepaticojejunostomy (HJ) strictures resistant to surgery and/or other interventions. MATERIALS AND METHODS: Eighteen patients who underwent percutaneous ERFA for HJ stricture were included. There were 10 men and 8 women with a mean age of 48.3±10.8 (SD) years (range: 33-69 years). The 18 patients had a total of 29 benign HJ strictures secondary to cholecystectomy (14 patients; 78.0%), Whipple procedure (3 patients; 16.6%) or blunt abdominal trauma (1 patient; 5.4%). The different end-points were technical success, clinical success, recurrence, procedure-related mortality, and morbidity. RESULTS: Technical and clinical success rates were 100% and 83.3%, respectively. No mortality and major procedure-related complications were observed. One patient experienced minor complication (self-limited pleural effusion). Two patients did not show favorable response to ERFA whereas 10 patients had no stricture recurrence during a mean follow-up period of 7.3 months±1.0 (SD) (range: 4-10 months). CONCLUSION: ERFA is a safe and effective treatment for benign HJ and biliary strictures. However, more studies involving more patients with a long-term follow-up period should be made to fully determine the long-term results of ERFA.

Multiple sclerosis in the province of Ferrara : evidence for an increasing trend.

BACKGROUND: Epidemiological studies on the distribution of multiple sclerosis (MS) conducted in the Mediterranean area in the last two decades have disclosed a significant increase in frequency of the disease, indicating caution when a latitude-related model of MS is accepted. Previous descriptive surveys in the province of Ferrara, northern Italy, carried out by our own epidemiological research group, have established that this area is at high risk for MS. OBJECTIVE: To confirm the above assumption and to update MS frequency estimates in this area. DESIGN AND SETTING: We conducted a community-based intensive prevalence and incidence study, by adopting a complete enumeration approach. RESULTS: On December 31, 2004, 423 patients (300 women and 123 men) suffering from definite or probable MS (Poser's criteria) living in the province of Ferrara, yielded a crude prevalence rate of 120.93 (95 % CI, 110.05-134.23) per 100,000, 164.26 for women and 73.59 for men. The average incidence from 1990 to 2003 was 4.35 per 100,000 (95 % CI, 3.77-4.99), 5.91 for women and 2.63 for men. The incidence rate,which was relatively stable during the previous 25 years (1965-1989) with a mean rate of 2.3 per 100,000, increased to a value of 3.39 per 100,000 in the period 1990-1994, 4.09 per 100,000 in the period 1995-1999 and 3.84 per 100,000 in the period 2000-2003. CONCLUSIONS: These results confirm that in Ferrara MS occurs more frequently than suggested by the geographic- related distribution model and, based on other recent national surveys, support the view that northern Italy is a high-risk area for the disease. The marked increase in MS prevalence rate, in comparison with previous investigations, is in part due to the increasing survival of patients as a result of improved supportive care and the accumulation of new incidence cases owing to the reduction in diagnostic latency for better quality of neurological diagnostic procedures. The incidence in the province of Ferrara was found to slowly change with an incremental trend,which cannot only be attributed to improvements in diagnostic ability. Environmental risk factors in genetically predisposed people over time could be considered.

Detection of anti-endomysial and anti-tissue transglutaminase autoantibodies in media following culture of oral biopsies from patients with untreated coeliac disease.

BACKGROUND AND AIMS: Coeliac disease is an autoimmune disorder characterised by high levels of anti-endomysial and anti-tissue transglutaminase autoantibodies in sera and media of cultured intestinal mucosa biopsies from affected patients. In this study, we wished to investigate whether anti-endomysial and anti-tissue transglutaminase antibodies can also be detected in culture media of oral mucosa specimens, and whether the mouth can be used as an area of immunological testing for coeliac disease. METHODS: Small intestine and cheek biopsy samples taken from 16 patients with active coeliac disease and from 11 controls were cultured in vitro for 48 h at 37 degrees C in presence of medium alone. Anti-endomysial and anti-tissue transglutaminase were detected in sera and in supernatants of these cultured biopsy samples by indirect immunofluorescence and enzyme immunoassay (EIA), respectively. RESULTS: Anti-endomysial and anti-tissue transglutaminase were positive in sera of 15/16 coeliac disease patients. Culture media of intestinal mucosa samples from 14/16 coeliac disease patients were anti-endomysial positive, while the same antibodies were positive in supernatants of cultured oral mucosa samples from 15/16 coeliac disease patients. Anti-tissue transglutaminase were positive in both intestinal and oral culture media of 15/16 coeliac disease patients. Neither anti-endomysial nor anti-tissue transglutaminase were found in sera or in culture supernatants of both intestinal and oral biopsy samples from 11 controls. CONCLUSIONS: Our study suggests a new immunological site to detect the pathognomonic autoantibodies of coeliac disease and confirms that the mouth is involved in this illness.

Impact of gluten-free diet on quality of life in celiac patients.

BACKGROUND AND AIM: Celiac disease (CD) is a common gluten-related disorder, whose only treatment is a gluten-free diet (GFD). Since a unique view on psychological consequences of a GFD still lacks, our aim was to assess the quality of life (QoL) and the depression state in symptomatic CD patients after GFD. Socio-demographic features were considered. PATIENTS AND METHODS: 210 adult CD patients were recruited and divided into 3 groups : 70 newly diagnosed patients (​Group A​),70 patients who have been on GFD for 6-12 months (​Group B​), and 70 patients who have been on GFD for more than 12 months (​Group C​). We recruited 210 healthy controls (​Group D). Psychological General Well-Being Index (PGWBI) and Beck Depression Inventory (BDI) questionnaires were administered. Each group was evaluated according to age, gender and school ranking. RESULTS: Groups A ​and B showed lower PGWBI scores compared with both Group C ​and D (p <0.001 for each comparison). Moreover, Groups A and B showed higher BDI scores compared with both ​Group C ​and D (p <0.001 for each comparison).Women, the elderly and the poorly educated seemed to suffer more psychological stress. CONCLUSION: GFD induces an improvement of well-being and a decrease of depression state after 12 months of strict GFD. Negative psychological implications were observed only in specific risk categories. (Acta gastroenterol. belg., 2016, 79, 447-453).
