综述亚洲b型流行性感冒(流感)嗜血杆菌(Hib)疾病和疫苗推广使用情况。流感嗜血杆菌是全世界儿童发病和死亡的主要原因之一,Hib常引起儿童严重感染。Hib结合疫苗的问世,大大减少了发达国家Hib疾病的发病率。尽管认识到Hib疾病的重要性,亚洲绝大多数国家仍未考虑使用这一疫苗,主要原因:亚洲国家Hib疾病负担不清楚和疫苗的价格。亚洲国家如何对待Hib疫苗问题:已知有高发病率的国家和地区应考虑使用;已经着手使用的国家应及时评价其免疫效果;疾病负担不清楚的国家与地区应与政府和专门机构积极合作,进一步开展相关研究。Hib疫苗使用应该提到决策机构的议事日程上来。 相似文献

Prior to possible introduction of large-scale vaccination programmes, an estimation and comparison of naturally acquired immunity against Haemophilus influenzae type b (Hib) was carried out in two populations of age-stratified infants and children (from birth to 14 years old) in Burkina-Faso (West Africa) (n = 206) and France (n = 206). Hib capsular polysaccharide antibodies were detected by an ELISA method. The difference in the percentages of minimum protective levels for the two populations were not significant (0.15 g/ml) for newborns (0–1 month) but became significant as early as 2 to 3 months of age (p < 0.01) when lower levels were found among infants from Burkina-Faso. Subsequently, the percentages in both countries remained low until 11 months of age and showed no significant differences. For children between 12 and 35 months, the results 0.15 g/ml were significantly higher in France (p 0.05). From 36 months, the percentage of minimum seropositivity increased in Burkina-Faso, so that the difference was no longer significant. In each country, the percentage of children with the minimum protective level varied significantly (p les; 0.05) according to age (0–47 months). None of the children from Burkina-Faso or France had antibody levels > 1.0 g/ml before one year of age. Thereafter, only 9.51% of French children in the 12- to 17-month age stratum and 19.2% over 4 years of age had antibody levels > 1.0 g/ml. There were no non-detectable results for children over 4 years of age, and the means for natural detectable Hib CP antibodies were > 0.15 g/ml for both populations. Hib invasive infections depend on climate, socioeconomic status and ethnic and genetic factors. In Burkina-Faso, the large number of infants and children under 4 years of age susceptible to Hib infections suggests that large scale vaccination programmes are needed soon after birth. However, it would first be necessary to evaluate such factors as the frequency of Hib diseases in this population. 相似文献

To estimate the incidence of Haemophilus influenzae type b (Hib) invasive disease in Italian infants we performed a prospective study in a cohort of newborns enrolled for a randomized trial on safety and efficacy of three pertussis vaccines and followed for onset of serious disease or pertussis. The overall cumulative incidence observed in 15,601 children was 51.3/100,000 for all invasive Hib infections and 38.4/100,000 for Hib meningitis, over 27 months of observation. The incidence density of all invasive Hib diseases was 28.7/100,000 person-years, while meningitis occurred with an incidence of 21.5/100,000 person-years. Among the eight cases detected, six were meningitis, one sepsis, and one cellulitis. The child with sepsis died. The incidence and epidemiology of invasive Hib disease in Italy are comparable to those reported from other European countries. Cost-benefit analyses are needed for planning Italian vaccination policy. 相似文献

流感嗜血杆菌(Haemophilus influenzae,Hi),尤其是b型(Hib)是引起儿童细菌性感染的主要病原体之一.过去的60年中,很多国家已广泛开展了对Hib各方面的研究,1980年代开始研制Hib疫苗进行预防相关疾病.1996年WHO将Hib蛋白结合疫苗引入各国扩大的计划免疫,至2004年9月,全球有94个国家(包括美洲、欧洲大部和澳洲)将这种疫苗纳入国家计划免疫,另有15个国家在全球疫苗与免疫联盟(GAVI)资助下使用这种疫苗,占全球所有国家和地区使用的一半.而我国尚未列入其中,原因之一是对Hib感染性疾病的认识还不够充分和深入.回顾我国有关Hib研究的整个历程,查询自40年代起至今中国学者关于Hib在国内外杂志发表的文章,现将主要内容总结如下. 相似文献

Introduction
Haemophilus influenzae type b (Hib) is a leading cause of bacterial meningitis and pneumonia and can be prevented by Hib vaccine. We conducted a vaccine impact evaluation to support continued use of Hib vaccine in Morocco following introduction in 2007.Methods
Bacterial meningitis surveillance data from 2004 to 2009 were obtained from 11 sentinel hospitals located in eight provinces and one prefecture in Morocco to examine Hi meningitis reporting for cases aged <5 years. We defined the years of 2004–2006 as the pre-vaccine period and 2008–2009 as the post-vaccine period and compared the mean annual number of confirmed Hi meningitis cases for these time periods using a Chi-square test. We calculated the minimum incidence of Hi meningitis during the evaluation period in Grand Casa Prefecture, where the catchment population could be estimated.Results
From 2004 to 2009, 1844 suspected meningitis case-patients aged <5 years were reported; 354 (19.2%) were confirmed with bacterial meningitis, including 105 (29.7%) Hi cases. The mean annual number of confirmed Hi meningitis cases decreased by 75%, from 24 in the pre-vaccine period to 6 during the post-vaccine period (p < 0.001). Assuming Hi cases with unknown age were <5 years of age, the estimated minimum incidence of confirmed Hi meningitis in Grand Casa Prefecture decreased by 93%, from 15 cases per 100,000 children in the pre-vaccine period to 1 case per 100,000 children in the post-vaccine period.Conclusion
Hib vaccine introduction likely significantly reduced the occurrence of Hi meningitis among children aged <5 years at the 11 sentinel hospitals included in this evaluation in Morocco, suggesting that continued use of Hib vaccine in Morocco would be beneficial. 相似文献17.

To inform World Health Organization recommendations regarding use of Haemophilus influenzae type b (Hib) vaccines in national immunization programs, a multi-country evaluation of trends in Hib meningitis incidence and prevalence of nasopharyngeal Hib carriage was conducted in four South American countries using either a primary, three-dose immunization schedule without a booster dose or with a booster dose in the second year of life. Surveillance data suggest that high coverage of Hib conjugate vaccine sustained low incidence of Hib meningitis and low prevalence of Hib carriage whether or not a booster dose was used. 相似文献

Haemophilus influenzae type b (Hib) still causes a substantial number of deaths among children in developing countries, despite the availability of effective conjugate vaccines. A major obstacle in developing a Hib vaccine has been limited awareness about the impact of Hib disease. A tool was developed to estimate the national rates of Hib meningitis and pneumonia by assessing retrospective local data over 7 to 10 days. Data from 11 countries in Africa, the Middle East, and Asia were studied and showed rates of Hib meningitis from >50 cases per 100,000 children >5 years in Ghana and Uganda to <15 per 100,000 in Iran, Jordan, and Uzbekistan. Results were affected by the quality of available data. The Hib rapid assessment tool can be useful to countries that desire a timely assessment of Hib disease rates. 相似文献
