Streptococcus pneumoniae infection has been the predominant cause of death among children with sickle cell anemia (SS). We report our observed change in the pattern of progression of septicemia to meningitis and death in nonimmunized SS children who were not receiving prophylactic penicillin in the face of a persistently high incidence of pneumococcal disease. Of 233 SS children less than ages 6 years observed for 781 person-years, the overall incidence rate of pneumococcal septicemia was 5.9 episodes per 100 person-years. Prior to July 1972, of 23 children who had pneumococcal septicemia, eight (35%) died and meningitis developed in 15 (65%), whereas since July 1972, 11 children have had pneumococcal septicemia, but no children died and meningitis developed in only two (18%). This decrease in major morbidity is attributed to the establishment of a clinical program that provides close medical supervision of the SS child with fever and the rapid institution of parenteral antibiotic therapy.
肺炎链球菌感染一直是镰状细胞贫血(SS)患儿死亡的主要原因。我们报告了在未接种疫苗且未接受预防性青霉素治疗的SS患儿中,败血症进展为脑膜炎及死亡模式的观察变化,尽管肺炎球菌疾病发病率持续居高。在对233名6岁以下的SS患儿进行了781人年的观察中,肺炎球菌败血症的总体发病率为每100人年5.9例。1972年7月之前,23名患肺炎球菌败血症的患儿中,8例(35%)死亡,15例(65%)发生脑膜炎;而自1972年7月以来,11名患儿患肺炎球菌败血症,但无患儿死亡,仅2例(18%)发生脑膜炎。主要发病率的下降归因于一项临床计划的实施,该计划对发热的SS患儿进行密切医疗监测,并迅速给予肠外抗生素治疗。
