摘要
导言:流感嗜血杆菌(Hi)又分为可分型(a-f)和不可分型两类。血清型 b 型流感嗜血杆菌(Hib)一直是造成入侵性感染的重要病原体之一。然而,在广泛接种 Hib 疫苗后,过去几十年中出现了其他 Hi 血清型,特别是 Hi 血清型 a(Hia),主要发生在 5 岁以下儿童中:病例介绍:我们介绍了两例颅内严重感染病例,患者年龄均大于 5 岁,且在短时间内和同一地理区域内检测到 Hia:为了更好地了解 Hia 的临床和流行病学特征,有必要对全球所有年龄组的 Hia 相关疾病进行流行病学研究和监测。结论:需要对全球所有年龄组的 Hia 相关疾病进行流行病学研究和监测,以更好地了解 Hia 的临床和流行病学特征,从而为开发可保护所有年龄组儿童的 Hia 候选疫苗建立一个平台。
Report of Haemophilus Influenzae serotype a intracranial infections in older children.
Introduction: Haemophilus influenzae (Hi) is subdivided into typeable (a-f) and non-typeable groups. Hi serotype b (Hib) has historically been one of the important pathogens responsible for invasive infection. However, after widespread Hib vaccination, the emergence of other Hi serotypes, specifically Hi serotype a (Hia), was noted during the last few decades, mostly in children younger than 5 years of age.
Case presentation: We present two cases of severe intracranial infections with detected Hia in patients > 5 years of age within a short time frame and within the same geographic area.
Conclusion: Epidemiological studies and surveillance on Hia-related illnesses in all age groups worldwide are needed to better understand the clinical and epidemiological characteristics of Hia. This can establish a platform to develop a candidate vaccine against Hia that might protect children of all ages.
