Sickle cell disease (SCD) is a public health problem in the Democratic Republic of Congo. While reference sickle cell centers have been implemented in capital cities of African countries and have proven to be beneficial for SCD patients. In the Democratic Republic of Congo, they have never been set up in remote areas for families with low or very low sources of income.
A cohort of 143 children with SCD aged 10 years old (IQR (interquartile range): 6-15 years) (sex ratio male/female = 1.3) were clinically followed for 12 months without any specific intervention aside from the management of acute events, and then for 12 months with a monthly medical visit, biological follow-up, and chemoprophylaxis (folic acid/penicillin), adequate fluids and malaria prevention.
The median age of patients at the diagnosis of SCD was 2 years (IQR: 1-5). The implementation of standardized and regular follow-ups in a new sickle cell reference center in a remote city showed an increase in the annual mean hemoglobin level from 50 to 70 g/L (p = 0.001), and a decrease in the lymphocyte count and spleen size (p < 0.001). A significant decrease (p < 0.001) in the average annual number of hospitalizations and episodes of vaso-occlusive crises, blood transfusions, infections, and acute chest syndromes were also observed.
The creation of a sickle cell reference center and the regular follow-up of children with sickle cell disease are possible and applicable in the context of a remote city of an African country and represent simple and accessible measures that can reduce the morbimortality of children with sickle cell disease.
镰状细胞病(SCD)是刚果民主共和国的一个公共卫生问题。虽然非洲国家的首都已设立了镰状细胞病参考中心,且已证明这些中心对SCD患者有益。但在刚果民主共和国,从未在偏远地区为收入低或极低的家庭设立过此类中心。
对143名年龄为10岁(四分位间距(IQR):6 - 15岁)的SCD儿童队列(男女比例为1.3)进行了为期12个月的临床随访,除了对急性事件进行处理外未进行任何特殊干预,随后又进行了12个月的随访,期间每月进行一次医学检查、生物学随访以及化学预防(叶酸/青霉素),保证充足液体摄入并预防疟疾。
SCD确诊时患者的中位年龄为2岁(IQR:1 - 5)。在一个偏远城市的新镰状细胞病参考中心实施标准化和定期随访后,年平均血红蛋白水平从50克/升升至70克/升(p = 0.001),淋巴细胞计数和脾脏大小有所下降(p < 0.001)。还观察到平均每年住院次数、血管闭塞性危象发作次数、输血次数、感染次数以及急性胸部综合征次数均显著减少(p < 0.001)。
在非洲国家的偏远城市建立镰状细胞病参考中心并对镰状细胞病患儿进行定期随访是可行且适用的,这是能够降低镰状细胞病患儿病死率和发病率的简单且可及的措施。
