Summary
The risk of developing hepatocellular carcinoma (HCC) in patients with thalassaemia is increased by transfusion‐transmitted infections and haemosiderosis. All Italian Thalassaemia Centres use an ad hoc form to report all diagnoses of HCC to the Italian Registry. Since our last report, in 2002, up to December 2012, 62 new cases were identified, 52% of whom were affected by thalassaemia major (TM) and 45% by thalassaemia intermedia (TI). Two had sickle‐thalassaemia (ST). The incidence of the tumour is increasing, possibly because of the longer survival of patients and consequent longer exposure to the noxious effects of the hepatotropic viruses and iron. Three patients were hepatitis B surface antigen‐positive, 36 patients showed evidence of past infection with hepatitis B virus (HBV). Fifty‐four patients had antibodies against hepatitis C virus (HCV), 43 of whom were HCV RNA positive. Only 4 had no evidence of exposure either to HCV or HBV. The mean liver iron concentration was 8 mg/g dry weight. Therapy included chemoembolization, thermoablation with radiofrequency and surgical excision. Three patients underwent liver transplant, 21 received palliative therapy. As of December 2012, 41 patients had died. The average survival time from HCC detection to death was 11·5 months (1·4–107·2 months). Ultrasonography is recommended every 6 months to enable early diagnosis of HCC, which is crucial to decrease mortality.
A multicenter randomized open-label long-term sequential deferiprone-deferoxamine (DFP-DFO) versus DFP alone trial (sequential DFP-DFO) performed in patients with thalassemia major (TM) was retrospectively reanalyzed to assess the variation in the left ventricular ejection fraction (LVEF) [1].Serial observations of LVEF over 3 years, in the same patient, were retrospectively assessed in 99 patients with TM during the sequential DFP-DFO multicenter randomized open-label trial [1]. A generalized estimating equation (GEE) model was used to demonstrate changes in mean LVEF over time [2].The regression coefficient of treatment suggested that the DFP-alone group showed a statistically significant increase in mean LVEF over time (coefficient 0.97, 95% CI (0.51; 1.44), P-value <0.0001).These findings suggest that long-term treatment with DFP-alone can significantly enhance LVEF over time. These findings agree with a survival analysis reporting a substantial decline in cardiac deaths during recent years, related to the switching of high-risk patients from DFO to chelation regimens that include the oral chelator DFP [3][4][5].Oral chelation treatment has improved greatly adherence and management of patients with TM [6,7].The improvement of the LVEF after 1-year DFP treatment has been reported [8][9][10][11].However, the effects of DFP on LVEF after long-term treatment have not been fully investigated.This letter reports a retrospective survey performed on patients with TM, previously enrolled in a long-term randomized open-label trial carrying ahead in Italy on the behalf of the Italian Society for the Study of Thalassaemia and Haemoglobinopathies (SoSTE) [1]. Ninety-nine out of 213 patients enrolled in the sequential DFP-DFO trial underwent longterm echocardiographic study of LVEF measured at baseline and every 12 months over three consecutive years (Fig. 1). Among these, 39 and 60 received sequential DFP (75 mg/kg for 4 days/week)-DFO (50 mg/kg for 3 days/week) or DFP-alone (75 mg/kg for 7 days/week) treatment, respectively (Table I).The hematological and clinical findings at enrollment are shown in Table I. No differences were observed at baseline between the two randomized groups. Particularly, the main findings of body iron overloading, expressed as serum ferritin at baseline, liver iron concentration (LIC), baseline LVEF <55%, and total number of blood transfusions were not statistically significantly different (Table I). Moreover, although baseline LVEF appears unlike between the two groups ( Fig. 1), this was not statistically significantly different (P-value 5 0.10, Table I).The DFP-alone group showed statistically significant increase over time in mean LVEF in comparison with sequential DFO-FP treatment (coefficient 0.97, 95% CI (0.51; 1.44), P-value <0.0001).Furthermore, the regression coefficient of treatment suggested that there was a statistically significant difference in mean LVEF between the two treated groups favoring the sequential group (coefficient 2.36, 95% CI (0.02; 4.71), P-value 5 0.047, but this ...
We assessed the familial aggregation of chronic lymphoproliferative diseases (CLD) in 3962 relatives of 169 patients with B-cell chronic lymphocytic leukemia (B-CLL). Data collection included a self-administered questionnaire. The "relative risk" considered the connection between a higher incidence of CLD and the degree of familial linkage with the probands. The model of logistic regression was statistically significant (p < 0.001), with the probability of CLD increasing in proportion to the relationship coefficient between parents, siblings and children [(relationship coefficient 0.5; probability of CLD 1.85 (C.I. 95%, range 1.1-3%)]. CLD, particularly B-CLL, were observed in first-degree relatives of the patients with B-CLL more often than in other relatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
