Survival and complications of beta-thalassemia in Lebanon: a decade's experience of centralized care.
beta-Thalassemia major is a debilitating disease with a considerable incidence in Lebanon (around 2-3% carriership). The present article describes our experience to this day with 214 patients, emphasizing the survival of beta-thalassemia major and development of complications among patients with different parameters. Fifteen deaths were reported. The most common cause of death was heart failure (60%). Patients with a ferritin level of 3,000 ng/ml showed better survival than those with a level >3,000 ng/ml (p < 0.006). In addition, patients with a ferritin level of 1,500 ng/ml showed less complication-free survival than those with a level >1,500 ng/ml (p < 0.024). High level of ferritin (1,500 ng/ml) is associated with increased risk of heart failure. Overall and complication-free survival were statistically different among patients classified according to birth cohort or ferritin level. The Chronic Care Center, a multidisciplinary center located in the suburbs of Beirut, led to an increase in complication-free as well as overall survival. Although patients are being diagnosed earlier and chelation therapy is being initiated at an earlier age, complications due to iron overload still persist. The introduction of new oral iron chelators and better iron overload quantitation methods will most likely modify this picture, and a follow-up study will examine their impact.
