Abstract Background: Group B streptococcus (GBS) or Streptococcus agalactiae are members of the normal flora of the female genital tract. GBS has become the major cause of bacterial infections in the peri-natal period, including bacteraemia, amnionitis, endometritis, and urinary tract infection in pregnant women as well as sepsis and meningitis in neonates and young infants. Infection of the new born may be acquired by the intra-amniotic route or directly during passage through the birth canal. Objectives: This study was undertaken to determine the prevalence of group B Streptococcus (GBS) colonization and to analyze related risk factors among pregnant women attending the antenatal clinic of Hawassa Health centre, Adare Hospital Hawassa, Ethiopia. Methods: A total of 139 pregnant women were screened for GBS colonization between May and June 2010. Standard microbiological methods were used to isolate and identify GBS from vaginal and ano-rectal swabs obtained from study subjects. An antimicrobial susceptibility test was performed for all GBS isolates according to the criteria of the Clinical and laboratory Standards Institute (CLSI) by disk diffusion method. Results: A total of 29 out of 139 (20.9%) pregnant women were colonized by GBS. No statistically significant association was observed for GBS colonization with any of socio-demographic characteristics of the study subjects including age, occupation, type of contraceptive used, parity, number of antenatal clinic visits. All GBS strains were susceptible to penicillin, ampicillin, vancomycin and gentamicin. Resistance was observed against erythromycin (6.9%), tetracycline (48.2%), ceftriaxone (10.3%), chloramphenicol (51.7%), ciprofloxacin (13.8%) and norfloxacin (10.3%). Conclusion: This study showed that prevalence of GBS colonization was 20.9% among the study subjects. The finding of this study was comparable with findings reported from developed and developing countries. However, further epidemiological investigations should be done in different parts of the country in order to know the actual GBS colonization rate in pregnant women and to consider the use of intra-partum antibiotics prophylaxis for prevention of early onset GBS-neonatal diseases.

Background: The attention given to HIV-infected children in terms of providing ART had so far taken a second rank. This was because primary concern is about adults. Objectives: This study had the objectives to estimate the survival duration and identify socio-economic, demographic and clinical predictor variables that affect the survival of HIV-infected children under ART. Methods: The data used in this study were obtained from the medical records of 255 HIV-infected children under the age of 15 who received ART in Felege-Hiwot Referral Hospital, Ethiopia. The Kaplan-Meier method and log-rank test allowed for comparison of survival of patients in different categories. Identification of predictors of survival was accomplished by employing the Cox proportional hazards regression model. Results: The mean survival time was found to be 22.4 months with standard deviation of 0.7 months. Baseline hemoglobin level, WHO clinical stage and age had significant impact on the survival of children during the 30 months of follow up. Conclusion: The risk of death among HIV-infected children with lower hemoglobin level in younger age groups was higher compared to those who were older and had higher hemoglobin level; the risk was highest in stage IV which was very similar to that in stage III.
背景:迄今为止,在提供抗逆转录病毒治疗方面对感染艾滋病毒儿童的关注处于次要地位。这是因为主要关注的是成年人。目的:本研究的目的是估计生存时间,并确定影响抗逆转录病毒治疗下感染艾滋病毒儿童生存的社会经济、人口统计学和临床预测变量。方法:本研究使用的数据来自埃塞俄比亚Felege-Hiwot转诊医院接受抗逆转录病毒治疗的255名15岁以下艾滋病毒感染儿童的医疗记录。Kaplan-Meier法和log-rank检验允许比较不同类别患者的生存。通过采用Cox比例风险回归模型确定生存预测因子。结果:平均生存时间为22.4个月,标准差为0.7个月。基线血红蛋白水平、WHO临床分期和年龄对患儿30个月随访期间的生存率有显著影响。结论:低龄组血红蛋白水平较低的hiv感染儿童死亡风险高于高龄组血红蛋白水平较高的儿童;风险在第四阶段最高,这与第三阶段非常相似。

Background: Recently measles outbreaks have been occurring in several areas of Ethiopia. Methods: Desk review of outbreak surveillance data was conducted to identify the susceptible subjects and highly affected groups of the community in Simada District, Amhara Region, May and June, 2009. Results: A total of 97 cases with 13 deaths (Case fatality Rate (CFR) of 13.4%) were reported delayed about 2 weeks. Cases ranged in of age range from 3 months to 79 years, with 43.3% aged 15 years and above; and high age specific attack rate in children under 5 and infants (p-value<0.0001). Conclusion and Recommendation: These findings indicate accumulation of susceptible children under 5 and a need to strengthen both routine and supplemental immunization activities (SIAs) and surveillance, with monitoring of accumulation of susceptible individuals to protect both target and non-target age groups. Surveillance should be extended to and owned by volunteer community health workers and the community, particularly in such remote areas.
背景:最近在埃塞俄比亚的几个地区发生了麻疹疫情。方法:对2009年5月和6月阿姆哈拉省西马达县暴发监测资料进行案头审查,确定社区易感人群和高感染人群。结果:共报告病例97例,死亡13例(病死率13.4%),延迟时间约2周。病例年龄在3个月至79岁之间,其中43.3%的病例年龄在15岁及以上;5岁以下儿童和婴幼儿的年龄特异性发病率较高(p值<0.0001)。结论和建议:这些发现表明5岁以下易感儿童的积累,需要加强常规和补充免疫活动(SIAs)和监测,监测易感个体的积累,以保护目标和非目标年龄组。监测应扩大到志愿社区卫生工作者和社区,并由其负责,特别是在这些偏远地区。

Background: Moringa stenopetala and related species are commonly used in folk medicine for various human diseases such as antimalarial, antihypertensive, antidiabetic and as antispasmodic. Objective: The aim of the study is to evaluate the effects of aqueous extract of M. stenopetala on blood parameters, and histopathology of liver and kidney in experimental mice. Methods: Fresh leaves of M. stenopetala were collected from Arbaminch area, Southwest Ethiopia, in November 2005. The leaves were dried and extracted with water. Three month-old Swiss albino male mice, which were kept under uniform laboratory conditions, were randomly divided into four groups (one group of controls and three experimental). (The control group was orally given 0.5 ml of distilled water, and groups II, III and IV were given the aqueous leaf extract of M. stenopetala using intragastric tube to achieve the required doses of 600, 750 and 900 mg/kg body weight, respectively once a day at 24 hours intervals for six weeks and then sacrificed). Blood sample was collected from each mouse and examined for hematological and biochemical parameters. Liver and kidney were removed, stained and examined for histopathological profiles. The effects of treatment with aqueous extract of M. stenopetala on hematological, biochemical and histopathology features were compared with control group following standard procedures. Results: Mice treated with 900 mg/kg of the extract per kg of body weight showed a significant increase in body weight compared to the controls ( P =0.014). Neither a significant change in the weight nor in histopathology of liver and kidney were observed in the animals treated with aqueous extract of M. stenopetala compared to those of the controls. Serum glucose level ( P =0.034) and serum cholesterol level ( P =0.016) decreased significantly after six weeks treatment. Conclusion: The aqueous leaf extract of M. stenopetala is shown to increase body weight and reduce serum glucose and cholesterol level in mice. This indicates nutritional and medicinal values, but we cannot yet recommend its therapeutic use before more and complete studies are done.
背景:辣木及其近缘种在民间医学中被广泛用于抗疟疾、降压、降糖和抗痉挛等多种人类疾病。目的:研究窄翅草水提物对实验小鼠血液指标及肝、肾组织病理学的影响。方法:2005年11月在埃塞俄比亚西南部的Arbaminch地区采集鲜叶。叶子被晒干后用水提取。在统一的实验室条件下饲养的3月龄瑞士白化病雄性小鼠,随机分为4组(1组为对照组,3组为实验组)。(对照组口服蒸馏水0.5 ml, II组、III组和IV组分别灌胃给药至所需剂量600、750和900 mg/kg体重,每天1次,间隔24小时,连续6周后处死)。从每只小鼠身上采集血样,检查血液学和生化参数。肝脏和肾脏被切除,染色并检查组织病理学特征。按照标准程序,比较窄足棘水提物处理对大鼠血液学、生化和组织病理学的影响。结果:每公斤体重900 mg/kg提取物处理的小鼠体重较对照组显著增加(P =0.014)。与对照组相比,用窄翅草水提取物治疗的动物体重和肝脏和肾脏的组织病理学没有明显变化。治疗6周后,血清葡萄糖水平(P =0.034)和血清胆固醇水平(P =0.016)显著降低。结论:窄荆芥叶水提物具有增加小鼠体重、降低血糖和胆固醇水平的作用。这表明了营养和药用价值,但在进行更多和完整的研究之前,我们还不能推荐其治疗用途。

Aim: To determine and describe the causes and risk factors predisposing Ethiopian patients to rhegmatogenous retinal detachment (RRD). Methods: A retrospective study of all patients with RRD seen at the retina clinic of Menilik II Hospital, Addis Ababa, from April 1999 to October 2003 was done. Charts of patients with the diagnosis of RRD were collected and data were filled on structured questionnaires and analyzed using EPI INFO 6 software. Results: Data were available for 276 patients (305 eyes) in whom the diagnosis of RRD was made. Age of patients ranged from 7-85 years; mean age was 41 and median was 40 years. Hundred-eighty-eight [68%] of the patients were males and 88 [32%] were females with male-to-female ratio of 2.1:1. Myopia was the predisposing factor for RRD in 78 [28.3%] patients of which 63 had myopia of > 5D. In 57 [20.7%] patients with RRD, there was a history of ocular trauma. Thirty-nine [14.2%] patients had had cataract surgery with lens implantation and 21 [7.6%] patients were surgically aphakic. Macula-off RRD was seen in 225 [73.8%] eyes. Bilateral RRD was seen in 29 [10.5%] patients. Conclusion: The study showed that myopia, ocular trauma, pseudophakia and aphakia in decreasing frequency were the main risk factors associated with RRD among Ethiopians attending a tertiary eye care centre.
目的:确定和描述埃塞俄比亚患者发生孔源性视网膜脱离(RRD)的原因和危险因素。方法:对1999年4月至2003年10月在亚的斯亚贝巴Menilik II医院视网膜诊所就诊的所有RRD患者进行回顾性研究。收集诊断为RRD的患者的图表,用结构化问卷填写数据,并使用EPI INFO 6软件进行分析。结果:276例(305只眼)诊断为RRD的患者资料可查。患者年龄7-85岁;平均年龄41岁,中位年龄40岁。男性88例(68%),女性88例(32%),男女比例为2.1:1。78例(28.3%)患者近视为RRD的易感因素,其中63例近视程度为bb0 ~ 5D。57例(20.7%)RRD患者有眼部外伤史。39例(14.2%)患者行白内障手术合并晶状体植入术,21例(7.6%)患者行手术无晶状体。黄斑脱落RRD 225只(73.8%)眼。29例(10.5%)患者出现双侧RRD。结论:该研究表明,在埃塞俄比亚三级眼科保健中心就诊的患者中,近视、眼外伤、假性晶状体和无晶状体的发生率下降是与RRD相关的主要危险因素。

Background: Globally, 41.8% of pregnant women and 30.2% of non-pregnant women are anemic. Previous studies which attempted to identify determinants of anemia among women of reproductive age reported conflicting findings. Objective: To assess the correlates of anemia among women of reproductive age in Ethiopia. Methods: A quantitative cross-sectional study carried out based on the secondary data of the Ethiopia Demographic Health Survey (EDHS) 2005. Data of a total of 5963 women of reproductive age were included in the analysis. Data were mainly analyzed using ANOVA and binary logistic regression. Result: The prevalence of anemia was 27.4% (95% CI: 26.3-28.5%). Rural residence, poor educational and economic status, 30-39 years of age and high parity were key factors predisposing women to anemia. Lactating women and those who gave birth in the month of the interview had 1.3 ( p = 0.000) and 2.2 ( p = 0.012) times higher risk than their counterparts. Those not using contraceptive were 1.4 times ( p = 0.02) more likely to develop anemia than current contraceptive users. The average Dietary Diversity Score (DDS) was only 4.01, and not more than 15% of the respondents consumed iron rich foods in the preceding day of the survey. Respondents with low DDS and those who did not consume iron rich foods in the reference period had significantly higher risk of anemia with odds ratio of 1.3 ( p = 0.01) and 1.3 ( p = 0.002), respectively. Utilizing maternity services, taking iron and vitamin A supplement during pregnancy and postpartum period, respectively, didn’t have a significant effect in reducing the burden of anemia. Recommendation: Family planning, economic and educational empowerment of women have affirmative inputs in combating anemia. A combination of nutrition, educational and livelihood promotion strategies should be instated to enhance dietary diversity. Maternal nutrition interventions should be integrated in a stronger manner into maternity services.
背景:在全球范围内,41.8%的孕妇和30.2%的非孕妇贫血。先前试图确定育龄妇女贫血决定因素的研究报告了相互矛盾的结果。目的:了解埃塞俄比亚育龄妇女贫血的相关因素。方法:基于2005年埃塞俄比亚人口健康调查(EDHS)的二手数据进行定量横断面研究。共有5963名育龄妇女的数据被纳入分析。数据分析主要采用方差分析和二元逻辑回归。结果:贫血发生率为27.4% (95% CI: 26.3 ~ 28.5%)。农村居住、教育和经济状况差、30-39岁和胎次高是妇女易患贫血的关键因素。哺乳期妇女和在采访当月分娩的妇女的风险分别是同龄妇女的1.3倍(p = 0.000)和2.2倍(p = 0.012)。未使用避孕措施的人患贫血的可能性是目前使用避孕措施的人的1.4倍(p = 0.02)。膳食多样性评分(DDS)平均值仅为4.01,调查前一天食用含铁丰富食物的比例不超过15%。低DDS的调查对象和参考期内未食用含铁丰富食物的调查对象患贫血的风险显著增加,比值比分别为1.3 (p = 0.01)和1.3 (p = 0.002)。利用产妇服务、孕期和产后分别补充铁和维生素A对减轻贫血负担没有显著效果。建议:计划生育、赋予妇女经济和教育权力对防治贫血有积极的投入。应制定营养、教育和促进生计战略相结合的战略,以加强饮食多样性。应更有力地将产妇营养干预措施纳入产妇服务。

Background: Schistosomiasis mansoni and soil-transmitted helminthiasis (STHs) are considerable medical and public health problems in Ethiopia. However, information is limited on the epidemiology of these infections in different localities even though it is needed to plan effective prevention and control measures. Objective: This study was designed to determine the prevalence of Schistosoma mansoni and soil-transmitted helminth infections in school children and residents in Bushulo village near Lake Awassa (Hawassa), southern Ethiopia. Methods: Cross-sectional epidemiological and parasitological studies were conducted on schistosomiasis mansoni and STHs in Bushulo village in May and June 2007. A total of 419 participants (353 school children and 66 other residents) were included in the study. The principal investigator interviewed the study subjects about demographic status using structured questionnaires. Moreover, experienced nurse took history and conducted physical examination to assess symptoms and signs related to chronic S. mansoni infection. A single stool sample was collected from each participant and processed using the Kato-Katz technique. Experienced laboratory technician read all slides at Bushulo Health Center. Results: The overall infection rates of schistosomiasis mansoni , trichuriasis, ascariasis and hookworm infection were 73.7%, 41.5%, 37.2% and 28.4%, respectively. Other parasitic infections observed were caused by Hymenolepis nana (1.7%), Taenia species (1.4%), and Enterobius vermicularis (1.4%). Children in the age range 10-14 years and those attending at St. Paul’s School had higher rates of T. trichiura and S. mansoni , respectively. Intensity of infection was higher for A. lumbricoides in the age range 5-9 years. The overall prevalence of any STHs was 67.3%. The rates of single, dual, triple and quadruple infections were 29.6%, 32%, 20.3% and 7.4%, respectively. Conclusion: The high prevalence and intensity of schistosomiasis mansoni and soil-transmitted helminthiasis makes periodic deworming programme urgent to reduce morbidity and transmission of helminthiasis in the area. Provisions of sanitary facilities and clean water supply as well as health education are also critically needed to sustain the impact of chemotherapy.
背景:曼氏血吸虫病和土壤传播蠕虫病(STHs)是埃塞俄比亚相当大的医疗和公共卫生问题。然而,尽管需要规划有效的预防和控制措施,但关于这些感染在不同地区的流行病学信息有限。目的:了解埃塞俄比亚南部阿瓦萨湖(Hawassa)附近的Bushulo村学童和居民中曼氏血吸虫和土壤传播蠕虫感染的流行情况。方法:于2007年5月和6月在布梭罗村对曼氏血吸虫病和血吸虫病进行了横断面流行病学和寄生虫学调查。共有419名参与者(353名学生和66名其他居民)参与了这项研究。主要研究者使用结构化问卷对研究对象进行了人口统计状况访谈。此外,经验丰富的护士记录病史并进行体格检查,评估慢性曼氏链球菌感染的相关症状和体征。从每位参与者收集一份粪便样本,并使用Kato-Katz技术进行处理。经验丰富的实验室技术员在布什罗健康中心阅读了所有的幻灯片。结果:曼氏血吸虫病、滴虫病、蛔虫病和钩虫病总感染率分别为73.7%、41.5%、37.2%和28.4%。其他寄生虫感染由微小膜膜绦虫(1.7%)、带绦虫(1.4%)和蛭状肠虫(1.4%)引起。10-14岁的儿童和圣保罗学校的学生分别有较高的trichiura和S. mansoni发病率。5 ~ 9岁的蛲虫感染强度较高。STHs的总患病率为67.3%。单次、双次、三次和四次感染分别为29.6%、32%、20.3%和7.4%。结论:该地区曼氏血吸虫病和土壤传播型血吸虫病流行率高、强度大,为降低血吸虫病发病率和传播率,有必要实施定期驱虫计划。还急需提供卫生设施和清洁水供应以及保健教育,以维持化疗的影响。

Introduction: Animal bites and scratches represent the most important public health issue related to dogs and cats because of the risk of rabies transmission associated with physical, psychological trauma and wound infection. Objective: The study was aimed at estimating the prevalence of animal bite of human beings in Addis Ababa. Methods: Data on the kind of animal, age of the patients, gender, site of bites and /or scratch were collected from the registry book and analyzed using SPSS version 11.5. Results: A total of 1299 cases of bite and/or scratch were reported for the period September 2008 to August 2009. The majority of bites were made by dogs where stray dogs are much higher (X 2 = 0.83, p= 0.36). There is statistically highly significant difference of bites between sex (p = 0.001) and between age group (F = 5.41, p=0.02). The animal bite made by dogs was higher on legs (55.6 %) followed by hands (26.45 %) and multiple bites (7.51 %). Conclusions: The majority of bites were attributed to stray dogs followed by cats, horses, donkeys. To reduce the problem a preventative public education is suggested.

Background: Since the advent of HAART, there is a significant reduction in opportunistic Infections (OIs), morbidity, mortality and HIV transmission. However, the low antiretroviral Therapy (ART) coverage in resource-limited countries (42%) and the presence of globally 500-800 thousand patients on first-line having to required switch to second-line drugs in 2010 are some concerns. Other challenges related to HAART include: lifelong therapy, failed treatment response, optimal time to start treatment and switching regimens, drug interaction, toxicity, cardiovascular risks, drug resistance, lost to follow-up, immune reconstitution inflammatory syndrome (IRIS), early mortality, and lack of restoration of solid immunity against HIV. To achieve the goals of ART, national ART programmes focus on the vital patient monitoring systems including clinical, immunologic, virologic, adherence, lost to follow-up and mortality. Objectives: This review is aimed at addressing the profile of immunovirological responses to HAART and the factors associated with, with a special emphasis on the drawbacks of immunologic assessment to diagnose virologic failures. Main findings: WHO recommends clinical and immunological assessments as surrogates of plasma viral load (VL) to identify first-line treatment failures in resource-poor settings. However, immunological tools have poor sensitivity (20-30%) and specificity (86-90%) to identify virologic failures that may lead to continue with failed regimen or to unnecessary switch of regimen which could result in a more complex profile of resistance. There are three main types of immunovirologic responders in clinical practice: concordant responders (40-60%), concordant non-responders (12-27.3%), and discordant responders that include lack of CD4+ increases despite viral suppression (7-48%), and optimal CD4+ responses in the absence of viral suppression (5-23.8%), whereby the risk of morbidity and mortality is higher in the concordant non-responders and discordant responders. Conclusions: ART benefits a substantial number of HIV patients even in resource-poor settings. Since clinicoimmunological assessments have lower performance in diagnosing virologic failures, moving towards the availability of VL testing to confirm treatment failures, if not pre-HAART resistance testing, is a logical and timely approach for resource limited countries like Ethiopia where the long-term effect of the roll-out ART is not well investigated. However, the high cost and technical demand of VL testing, lack of experience of health professionals, weak infrastructure and health care system, the unavailability and high costs of second-line drugs could be the major challenges during expansion of VL testing. Moreover, longitudinal studies on long-term effects of HAART, and surveys focused on transmitted or acquired HIV drug resistance, and Early Warning Indicators are highly pertinent.
背景:自从HAART出现以来,机会性感染(oi)、发病率、死亡率和HIV传播显著降低。然而,在资源有限的国家,抗逆转录病毒治疗(ART)的覆盖率较低(42%),以及2010年全球有50 -80万一线患者必须改用二线药物,这些都令人担忧。与HAART相关的其他挑战包括:终身治疗、治疗反应失败、开始治疗和转换方案的最佳时间、药物相互作用、毒性、心血管风险、耐药性、失去随访、免疫重建炎症综合征(IRIS)、早期死亡以及缺乏针对艾滋病毒的坚实免疫恢复。为了实现抗逆转录病毒治疗的目标,国家抗逆转录病毒治疗规划侧重于重要的患者监测系统,包括临床、免疫学、病毒学、依从性、随访缺失和死亡率。目的:本综述旨在解决HAART的免疫病毒学反应概况及其相关因素,特别强调免疫评估诊断病毒学失败的缺点。主要发现:世卫组织建议将临床和免疫学评估作为血浆病毒载量(VL)的替代指标,以确定资源贫乏环境中一线治疗失败的情况。然而,免疫学工具在识别病毒学失败方面的敏感性(20-30%)和特异性(86-90%)较差,这些病毒学失败可能导致继续失败的方案或不必要的方案转换,这可能导致更复杂的耐药情况。在临床实践中,有三种主要类型的免疫病毒学应答者:和谐应答者(40-60%),和谐无应答者(12-27.3%)和不和谐应答者(包括尽管病毒抑制但缺乏CD4+增加(7-48%),以及在没有病毒抑制的情况下最佳CD4+应答者(5-23.8%),因此,和谐无应答者和不和谐应答者的发病率和死亡率风险更高。结论:即使在资源贫乏的环境中,抗逆转录病毒治疗也使大量艾滋病毒患者受益。由于临床免疫学评估在诊断病毒学失败方面的表现较差,因此,对于资源有限的国家,如埃塞俄比亚,这是一种合乎逻辑的及时方法,因为在这些国家,推广抗逆转录病毒治疗的长期效果尚未得到很好的调查。然而,VL检测的高成本和技术需求、卫生专业人员缺乏经验、基础设施和卫生保健系统薄弱、二线药物的不可获得性和高成本可能是扩大VL检测的主要挑战。此外,关于HAART长期效果的纵向研究,以及侧重于传播或获得性艾滋病毒耐药性的调查,以及早期预警指标都是高度相关的。
