Sickle cell disease is a group of conditions characterized by production of abnormal hemoglobin, with clinical manifestations that vary by genotype and age.
To discuss current public health issues associated with sickle cell disease, and approaches to preventing complications from these conditions in the United States.
Literature review.
Most clinical interventions for people with sickle cell disease discussed in the medical literature can be classified as tertiary prevention: for example, therapy to ameliorate anemia, reduce the frequency of pain crises, or prevent stroke recurrences. A form of secondary prevention, newborn screening, has emerged as an important public health approach to identifying affected children before they develop complications. Newborn screening is the starting point for simple public health strategies such as parental education, immunization, and penicillin prophylaxis. Identification of affected families by newborn or community screening programs has also been an entry point for genetic counseling, although utilization of prenatal testing has varied by factors such as geographic location. Public health agencies have had significant involvement with funding, policy making, and formulation of laboratory and clinical guidelines for sickle cell disease. Since the introduction of penicillin prophylaxis policies, newborn screening, new immunizations, and comprehensive medical care centers, the survival of young children with sickle cell disease has improved.
Although the efforts of preventive medicine providers in public health programs are not solely responsible for the improved survival of children with sickle cell disease, such programs remain an important component in preventing sickle cell complications.
镰状细胞病是一组以产生异常血红蛋白为特征的疾病,其临床表现因基因型和年龄而异。
探讨与镰状细胞病相关的当前公共卫生问题,以及在美国预防这些疾病并发症的方法。
文献综述。
医学文献中讨论的针对镰状细胞病患者的大多数临床干预措施可归类为三级预防:例如,改善贫血、减少疼痛危象频率或预防中风复发的治疗。二级预防的一种形式,即新生儿筛查,已成为在受影响儿童出现并发症之前识别他们的重要公共卫生方法。新生儿筛查是诸如家长教育、免疫接种和青霉素预防等简单公共卫生策略的起点。通过新生儿或社区筛查项目识别受影响的家庭也是遗传咨询的切入点,尽管产前检测的利用因地理位置等因素而异。公共卫生机构在镰状细胞病的资金、政策制定以及实验室和临床指南的制定方面发挥了重要作用。自引入青霉素预防政策、新生儿筛查、新的免疫接种和综合医疗中心以来,镰状细胞病幼儿的生存率有所提高。
虽然公共卫生项目中预防医学提供者的努力并非镰状细胞病患儿生存率提高的唯一原因,但此类项目仍是预防镰状细胞病并发症的重要组成部分。
