We reviewed our experience with bacteremic pneumococcal pneumonia (BPP) over a 1-year period at a 600-bed community teaching hospital; 26 cases were identified. The mean age was 57.5 years and there were 12 male and 14 female subjects. Cough, sputum production, fever, and mental status changes were the most frequent symptoms. Risk factors included drug abuse in 10, HIV in 4, current smoking in 7, diabetes in 3, and cancer in 3. The mean PaO2/FIo2 ratio was 274. Radiographic features included a consolidation pattern in 7, bronchopneumonia in 15, combined in 1, and an initial normal film in 3. Average length of stay (LOS) was 11 days with an overall mortality of 11.5%. Four patients required mechanical ventilation, two meeting the criteria for ARDS (if this group were eliminated, LOS would be 8.4 days). Three of these survived. Four patients had organisms resistant to penicillin and all survived. We conclude that (1) BPP remains a serious but treatable infection particularly when utilizing full supportive care; (2) the bronchopneumonia x-ray film pattern was associated with all the mortality; and (3) the occurrence of penicillin resistance did not contribute to the mortality, since early recognition and the use of appropriate antibiotics saved all of these patients.
我们回顾了一家拥有600张床位的社区教学医院在1年时间里收治的菌血症性肺炎球菌肺炎(BPP)患者的情况;共确诊26例。患者平均年龄为57.5岁,男性12例,女性14例。咳嗽、咳痰、发热及精神状态改变是最常见的症状。危险因素包括药物滥用10例、HIV感染4例、当前吸烟者7例、糖尿病3例、癌症3例。平均PaO2/FIo2比值为274。影像学特征包括实变影7例、支气管肺炎15例、两者兼有1例、初始胸片正常3例。平均住院时间(LOS)为11天,总死亡率为11.5%。4例患者需要机械通气,其中2例符合急性呼吸窘迫综合征(ARDS)标准(若排除该组患者,住院时间将为8.4天)。其中3例存活。4例患者的病原体对青霉素耐药,但均存活。我们得出结论:(1)BPP仍然是一种严重但可治疗的感染,尤其是在采用全面支持治疗时;(2)支气管肺炎的胸片表现与所有死亡病例相关;(3)青霉素耐药的发生并未导致死亡,因为早期识别和使用适当的抗生素挽救了所有这些患者。
