Our aim was to describe the numbers and distribution of patients with different types of thalassemia and to assess the standards of care in all thalassemia treatment centers throughout Sri Lanka and the success of the ongoing prevention programme.
This cross-sectional island-wide survey was conducted by two trained medical graduates, who visited each thalassemia center to collect data from every patient, using a standardized form. Data was collected through review of patient registers and clinical records.
We collected data on 1774 patients from 23 centers. 1219 patients (68.7%) had homozygous β-thalassemia, 360 patients (20.3%) had hemoglobin E β-thalassemia, and 50 patients (2%) had sickle β-thalassemia. There were unacceptably high serum ferritin levels in almost all centers. The annual number of births of patients with β-thalassaemia varied between 45-55, with little evidence of reduction over 19 years.
Central coordination of the treatment and ultimately prevention of thalassemia is urgently needed in Sri Lanka. Development of expert centers with designated staff with sufficient resources will improve the quality of care and is preferred to managing patients in multiple small units.
本研究旨在描述不同类型地中海贫血患者的数量和分布,并评估斯里兰卡所有地中海贫血治疗中心的治疗标准,以及正在进行的预防计划的效果。
本横断面全岛调查由两名经过培训的医学毕业生进行,他们走访每个地中海贫血中心,使用标准化表格从每位患者处收集数据。通过查阅患者登记册和临床记录收集数据。
我们从 23 个中心收集了 1774 名患者的数据。1219 名患者(68.7%)患有纯合子β地中海贫血,360 名患者(20.3%)患有血红蛋白 Eβ地中海贫血,50 名患者(2%)患有镰状细胞β地中海贫血。几乎所有中心的血清铁蛋白水平都高得令人无法接受。β地中海贫血患者的年出生率在 45-55 之间,19 年来几乎没有减少的迹象。
斯里兰卡迫切需要中央协调地中海贫血的治疗,最终实现预防。建立有指定人员和充足资源的专家中心将提高治疗质量,优于在多个小型单位管理患者。
