Association of celiac disease in patients with multiple sclerosis in Tuscany

BACKGROUND AND STUDY PURPOSE: to describe the comorbidity of celiac disease among a large cohort of multiple sclerosis patients in Tuscany. METHODS: the association of celiac disease among multiple sclerosis adult patients (n=2050) was retrospectively evaluated. RESULTS: 13 patients were diagnosed with celiac disease, the female:male ratio was 3.3:1 and the median age at diagnosis was 34.2 years (SD 13). Seventy-seven per cent of subjects complained about gastrointestinal symptoms. IgA anti- transglutaminase was positive in 85 % of cases and there was 70 % of villous atrophy. CONCLUSIONS: the frequency of celiac disease among multiple sclerosis patients examined was lower than in the general population, 0.6 % vs 1 %)(p = 0.65)

Treatment of multiple sclerosis with rituximab: A multicentric Italian-Swiss experience.

BACKGROUND: Rituximab, an anti-CD20 monoclonal antibody leading to B lymphocyte depletion, is increasingly used as an off-label treatment option for multiple sclerosis (MS). OBJECTIVE: To investigate the effectiveness and safety of rituximab in relapsing-remitting (RR) and progressive MS. METHODS: This is a multicenter, retrospective study on consecutive MS patients treated off-label with rituximab in 22 Italian and 1 Swiss MS centers. Relapse rate, time to first relapse, Expanded Disability Status Scale (EDSS) progression, incidence of adverse events, and radiological outcomes from 2009 to 2019 were analyzed. RESULTS: A total of 355/451 enrolled subjects had at least one follow-up visit and were included in the outcome analysis. Annualized relapse rate significantly decreases after rituximab initiation versus the pre-rituximab start year in RRMS (from 0.86 to 0.09, p < .0001) and in secondary-progressive (SP) MS (from 0.34 to 0.06, p < .0001) and had a slight decrease in primary-progressive (PP) MS patients (from 0.12 to 0.07, p = 0.45). After 3 years from rituximab start, the proportion of patients with a confirmed EDSS progression was 14.6% in the RRMS group, 24.7% in the SPMS group, and 41.5% in the PPMS group. No major safety concerns arose. CONCLUSION: Consistently with other observational studies, our data show effectiveness of rituximab in reducing disease activity in patients with MS.

Markers of JC virus infection in patients with multiple sclerosis under natalizumab therapy.

OBJECTIVE: To evaluate the frequency of JC polyomavirus (JCPyV) infection and anti-JCPyV antibodies in patients with multiple sclerosis under natalizumab therapy. METHODS: Presence of anti-JCPyV antibodies and JCPyV DNA was analyzed in 39 patients with relapsing-remitting multiple sclerosis undergoing natalizumab therapy. Anti-JCPyV antibodies were evaluated in serum by a 2-step virus-like particle-based ELISA assay (Stratify), and JCPyV DNA was evaluated in peripheral blood mononuclear cells, plasma, and urine by quantitative PCR. The anti-JCPyV antibodies were evaluated in serum samples collected at the same time or later than those collected for DNA analysis. RESULTS: JCPyV DNA was detected in 59% of patients, and anti-JCPyV antibodies were present in 67%. JCPyV DNA occurred more often in blood than in urine. Anti-JCPyV antibodies were observed in 70% of the JCPyV-infected patients, and JCPyV DNA was detected in 50% of the patients without anti-JCPyV antibodies. When JCPyV DNA was investigated in blood and urine the frequency of infection was higher than previously described. CONCLUSION: Under these experimental conditions, with respect to the observed frequency of JCPyV infection, the sensitivity of the anti-JCPyV antibody assay was lower than expected.

[Prevalence of dementia in Tuscany: results from four population-based epidemiological studies]. / La prevalenza della demenza in Toscana: i risultati di quattro studi epidemiologici di popolazione.

OBJECTIVE: to provide information on epidemiology of dementia in Tuscany needed to plan for dedicated health and social services. DESIGN: analysis of pooled baseline data from 4 population-based longitudinal studies. SETTING: 4 municipalities in Tuscany. PARTICIPANTS: 4,056 elderly subjects enrolled in 4 longitudinal studies. MAIN OUTCOME MEASURES: age- and sex-specific dementia prevalence rates and estimated number of demented people, by degree of cognitive impairment and BADL disability in the elderly population of Tuscany. RESULTS: out of the evaluated subjects, 293 are demented. Prevalence of dementia increases from about 1 % in the 65-69 age group to about 28 % in the 90+ age group both among women and men. About 43% of the demented study subjects suffer from severe mental deterioration (MMSE < 14) and56% are disabled in at least one Basic Activity of Daily Living (BADL). We estimate that about 19 thousand demented elderly men and 40 thousand demented elderly women are currently living in Tuscany of whom 26 thousand severely mentally impaired and 34 thousand disabled in at least one BADL. The resulting overall dementia prevalence standardised on the Italian 65+ population is 5,3% for men and 7,7% for women. CONCLUSIONS: these estimates could be used as a basis for the evaluation and the planning of social and health care services dedicated to demented people.
