Between 1991 and 1995, 2554 children under 5 years old hospitalized with severe acute lower respiratory tract infection in Al-Sabe'en, Sana'a, Yemen were studied. 47.7 per cent (1218) were under 6 months of age and 74.1 per cent (1893) were in their first 12 months. Sixty-four per cent (1633) were males. Of the 2554 cases, 221 died (overall, a case fatality rate of 8.7 per cent). 118 of the deaths (53.4 per cent) were in the under 6 months age group and 188 (85 per cent) were in the first 12 months age group. During 1995 the hospital started adopting the WHO standard case-management guidelines for treating severe acute lower respiratory tract infections. There were no significant reductions in case fatality rates in 1995 (CFR 9.8 per cent) compared with those of 1991 (CFR 7.9 per cent), 1992 (CFR 9.4 per cent), 1993 (CFR 7 per cent), or 1994 (CFR 8.5 per cent). Factors such as late hospital admission with cyanosis, malnutrition, rickets as well as increased resistance of the common causative organisms (pneumococci and H. influenzae) to antibiotics recommended by the WHO may have contributed to such a high case fatality rate remaining unchanged. In addition to reducing the risk of developing pneumonia and dying from pneumonia by improving maternal nutrition, health education, promoting breastfeeding, and preventing rickets and nutritional anaemia among the vulnerable age groups, vaccination against pneumococci and H. influenzae type b should be seriously considered as one of the strategies to reduce lower respiratory tract infection-related mortality.
1991年至1995年期间,对也门萨那市萨贝因医院收治的2554名5岁以下患有严重急性下呼吸道感染的儿童进行了研究。其中47.7%(1218名)年龄在6个月以下,74.1%(1893名)在出生后的头12个月内。64%(1633名)为男性。在这2554例病例中,221例死亡(总体病死率为8.7%)。其中118例死亡(53.4%)发生在6个月以下年龄组,188例(85%)发生在头12个月年龄组。1995年,该医院开始采用世界卫生组织治疗严重急性下呼吸道感染的标准病例管理指南。与1991年(病死率7.9%)、1992年(病死率9.4%)、1993年(病死率7%)或1994年(病死率8.5%)相比,1995年的病死率(9.8%)没有显著降低。诸如出现紫绀后入院较晚、营养不良、佝偻病以及常见病原体(肺炎球菌和流感嗜血杆菌)对抗生素的耐药性增加等因素,可能是导致如此高的病死率保持不变的原因。除了通过改善孕产妇营养、健康教育、促进母乳喂养以及预防脆弱年龄组的佝偻病和营养性贫血来降低患肺炎和死于肺炎的风险外,还应认真考虑将肺炎球菌和b型流感嗜血杆菌疫苗接种作为降低下呼吸道感染相关死亡率的策略之一。
