Acute myeloid leukemia in Italian patients with multiple sclerosis treated with mitoxantrone
none 25 no Abstract OBJECTIVES: To evaluate the incidence and dose-dependency of mitoxantrone (MTX)-associated acute myelocytic leukemia (AML) in the network of Italian multiple sclerosis (MS) clinics. METHODS: We performed a multicenter retrospective cohort study of patients treated with MTX in MS centers under the Italian national health care system between 1998 and 2008. Demographic, disease, treatment, and follow-up information were collected using hospital records. RESULTS: Data were available for 3,220 patients (63% women) from 40 Italian centers. Follow-up (mean ± SD) was 49 ± 29 months (range 12-140 months). We observed 30 cases of AML (incidence 0.93% [95% confidence interval 0.60%…
Multiple sclerosis in twins from continental Italy and Sardinia: a nationwide study.
Knowledge about the balance between heritable and nonheritable risk in multiple sclerosis (MS) is based on twin studies in high-prevalence areas. In a study that avoided ascertainment limitations and directly compared continental Italy (medium-prevalence) and Sardinia (high-prevalence), we ascertained 216 pairs from 34,549 patients. This gives a twinning rate of 0.62% among MS patients, significantly less than that of the general population. In continental Italy, probandwise concordance was 14.5% (95% confidence interval, 5.1-23.8) for monozygotic and 4.0% (95% confidence interval, 0.8-7.1) for dizygotic twins. Results in Sardinia resemble those in northern populations but in limited number…
Attività anti-proliferativa di derivati di organostagno(IV) con Na-Boc-Ornitina e studio dell’azione pro-apoptotica del derivato Ph3Sn(Boc- Orn)
Nuovi composti di organostagno(IV) [R3SnL e R¢2SnL2 (R = Me, Ph e R¢= Me, nBu, HL= Na-Boc-Ornitina)] sono stati sintetizzati e caratterizzati sia allo stato solido (FT-IR) che in soluzione (1H e 13C NMR) per poterne valutare la citotossicità in linee cellulari tumorali [1]. Na-Boc-Ornitina si comporta come un legante chelante dello stagno con il gruppo carbossilato, mentre il gruppo amminico Na-protetto è esente dalla coordinazione. I composti sono stati testati per l’attività citotossica in vitro su cellule neoplastiche umane HepG2 di epatocarcinoma ed MCF7 di cancro al seno. L’effetto dei composti, nel range da 0.5 a 25 μM, dopo 24 h di incubazione è stato valutato mediante saggio MTT. Il…
