Background Mitoxantrone (MX) has been used as second line therapy for aggressive multiple sclerosis (MS). Potential cardiotoxic effects of MX limit its use; a cumulative dose of up to 100 mg/m2, has ...been long considered relatively safe. We calculated the frequency of cardiac side effects in MS patients treated with MX. Methods We performed a cohort study including all MS patients treated with MX at the Neurological Department of the University Hospital of Palermo, Italy. Two hundred-sixty-four MS patients diagnosed according to validated criteria were included and followed-up until the end of September 2010. Patients were treated with MX as a second line therapy if they had no previous heart diseases determined by clinical evaluation, electrocardiography, and echocardiography. Treatment administration was made at a monthly dose of 8 mg/m2 for the first three months and at a dose of 12 mg/m2 every three months. Echocardiography was routinely performed every six months. Treatment was stopped before reaching the final dose if signs had appeared of impaired heart function, confirmed left ventricular ejection fraction reduction lower to 50%, or a confirmed reduction of more than 10% with respect to the first examination. Results Heart involvement was observed in 12.4% of treated individuals, and symptomatic congestive heart failure occurred in 2.7% of the cohort. A patient had a myocardial infarction, and 3.1% showed electrocardiographic anomalies not present at baseline. Conclusion Our study confirms that cardiac adverse events associated with MX are more common than previously reported.
The global burden of neurodegenerative diseases is increasing. Previous studies reported differences related to age, gender and socioeconomic status. We calculated the cognitive performances of a ...Sicilian population aged 65 years or older, by means of a door-to-door population-based survey in Bagheria city, Sicily.
A door-to-door survey was carried out in the city of Bagheria, Sicily (prevalence day September 30, 2006). A cohort of 2,200 persons was randomly stratified, obtaining a 25% sample of the whole population. Cognitive function was assessed by Mini Mental State Examination (MMSE). Percentile distributions by age, gender, education and working activity were calculated. Regression models were used to analyze the relationship between the investigated variables and cognitive performance.
A total of 1,837 persons agreed to participate (1,062 women and 775 men). Distribution of MMSE showed a highly significant inverse linear trend related to the increasing age (p < 0.0001) and to the degree of education (p < 0.0001), both in men and women. We observed a significant association between higher education and a better cognitive performance (OR 6.91; CI 3.24-14.76) and an inverse association between manual kind of occupation versus not manual and a poorer cognitive status (OR 0.82; CI 0.67-0.997). Height was associated with decreased cognitive performances in women (OR = 1.03; CI = 1.01-1.05) but not in men (OR = 0.997; CI = 0.993-1.002).
These findings provide a feature of cognitive performances in Sicily, measured by MMSE scores in individuals aged 65 years or older.
