Zusammenfassung 63 Neugeborene wurden nach insgesamt 93 Austauschtransfusionen während eines Zeitraumes bis zu 6 Monaten auf das Risiko einer Transfusionshepatitis untersucht. Dabei wurden zusätzlich zur klinischen Beobachtung die Transaminasen und der Nachweis des Australia-Antigens als Kontrollkriterien gewertet. Klinisch wurde in keinem Fall eine Hepatitis beobachtet, eine SGPT-Erhöhung nach 3 Monaten in einem Fall könnte für eine anikterische Hepatitis sprechen. Ein Australia-Antigen-Nachweis konnte bei negativen Ausgangsbefunden bei Spendern und Empfängern nirgends in den Nachuntersuchungen erbracht werden. Demnach ist das Hepatitisrisiko einer Austauschtransfusion bei Wahrung der heute üblichen Spenderauslese praktisch nicht zu befürchten.  相似文献

17 alpha-Alkylated androgens are highly effective in preventing attacks in HAE patients. These drugs, however, seem to be implicated in the development of cholestatic jaundice, peliosis hepatis, and liver tumors. In order to assess the risk-benefit balance of the long-term therapy with androgen derivatives, a follow-up investigation was performed in 13 HAE patients. The results of this study indicate that long-term treatment (15 to 47 mo) with low doses of danazol or stanozolol does not induce significant hepatic damage detectable by laboratory tests or liver biopsy. However, the limited number of patients, although in a rather long period of observation, still suggests a careful control and the use of minimal effective doses.  相似文献

The purpose of this study was to identify the most cost effective method for screening subjects for hepatitis B vaccination. Such a method would ideally permit detection of all susceptible individuals at the lowest possible cost.Two-hundred-five hospital workers from the Piedmont region of Italy participated in the study. The sero-epidemiological conditions of this group with regard to hepatitis B markers was representative of hospital workers in this region as a whole. All subjects, excluding carriers, persons with anti-HBs titers 10 mIU and subjects positive for anti-HBc at a 1/100 dilution, were vaccinated. Their responses were evaluated 15 days and 1 month after vaccination. The presence of a booster effect following vaccination was correlated with the immunological status of the subject at the time of pre-vaccination screening.In the light of the results obtained, 5 screening procedures and the procedure of vaccination without screening were evaluated. The most cost effective screening strategy proved to be that of sequential testing for anti-HBc, anti-HBs and finally HBsAg and vaccination of the following subjects: those who were negative for anti-HBc, those who were anti-HBc-positive with anti-HBs titers 10相似文献

Despite access to a safe and effective vaccine, mother-to-child transmission (MTCT) of hepatitis B virus (HBV) persists in Africa. This is of concern since perinatally-infected infants are at highest risk of developing hepatocellular carcinoma, a life-threatening consequence of chronic HBV infection. While tools to prevent HBV MTCT are available, the cost implications of these interventions need consideration prior to implementation. A Markov model was developed to determine the costs and health outcomes of (1) universal HBV birth dose (BD) vaccination, (2) universal BD vaccination and targeted hepatitis B immunoglobulin (HBIG), (3) maternal antiviral prophylaxis using sequential HBV viral load testing added to HBV BD vaccination and HBIG, and (4) maternal antiviral prophylaxis using sequential HBeAg testing combined with HBV BD vaccination and HBIG. Health outcomes were assessed as the number of paediatric infections averted and disability-adjusted life years (DALYs) averted. Primary cost data included consumables, human resources, and hospital facilities. HBV epidemiology, transitions probabilities, disability weights, and the risks of HBV MTCT were extracted from the literature. Incremental cost-effectiveness ratios (ICERs) were calculated to compare successive more expensive interventions to the previous less expensive one. One-way sensitivity analyses were conducted to test the robustness of the model’s outputs. At the Namibian cost/DALY averted threshold of US$3 142, the (1) BD vaccination + targeted HBIG, and (2) maternal antiviral prophylaxis with sequential HBeAg testing interventions were cost-effective. These interventions had ICERs equal to US$1909.03/DALY and US$2598.90/DALY averted, respectively. In terms of effectiveness, the maternal antiviral prophylaxis with sequential HBeAg testing intervention was the intervention of choice. The analysis showed that elimination of HBV MTCT is achievable using maternal antiviral prophylaxis with active and passive immunization. There is an urgent need for low cost diagnostic tests to identify those women who will most benefit from drug therapy to attain this laudable goal.  相似文献

本文用多种单克隆抗体对32例慢性肝炎患者的细胞免疫状况进行了研究。结果发现患者肝组织内淋巴细胞和单核、巨噬细胞浸润明显增加,坏死区浸润细胞主要是T_3~+和T_8~+细胞。B淋巴细胞浸润极少,浸润淋巴细胞表面IL—2受体阳性细胞与外周血淋巴细胞表面IL—2受体阳性细胞率均无改变。患者外周血单个核细胞改变为T_3~+下降,T_4/T_8比例下降,单核、巨噬细胞、B淋巴细胞及淋巴细胞表面HLA—DR、DP、DQ标志与正常人无差异。  相似文献

Day wetting     
About 1% of healthy children over the age of 5 years have troublesome daytime wetting. Two-thirds of those who wet by day are reliably dry at night. The problem is more common in girls and is usually the result of urge incontinence. Although the wetting may be exacerbated by giggling and/or stress, pure giggle micturition and isolated stress incontinence are both rare. There is a strong association with bacteriuria (50% prevalence) in girls who wet by day. A potentially important relationship exists between day wetting, infection, reflux and upper tract damage, which is expressed in an extreme form in the syndromes of incoordinated voiding and progressive renal damage. Most children who wet by day have unstable bladders. Many of them adopt characteristic holding postures. There is an increased incidence of emotional disorder compared with children who merely wet the bed. Between 10% and 15% of children who wet by day become dry during the next 12 months. The acquisition of dryness is accelerated by eradication of bacteriuria and a sympathetic and energetic management regime, which should place responsibility on the child and result in the child voiding more frequently and completely. Reminder alarms and other behaviour therapies have proved effective. There is no satisfactory evidence for the efficacy of drugs. More complex behavioural training regimes including biofeedback are valuable for severe cases.  相似文献

目的 分析我国消除丙型肝炎(丙肝)的普通人群HCV检测策略的成本效果,明确最佳成本效果的HCV检测年龄。方法 运用TreeAge pro 2019软件构建决策树马尔科夫模型,以1年为周期,模拟10万名20~59岁各年龄组人群HCV检测和治疗结果,以全社会角度分析策略间比较的成本效果和效益。效果指标为增量成本效果比(ICER),效益指标为净货币效益(NMB),以我国2022年人均国内生产总值(85 698元)为意愿支付阈值。通过单因素敏感性分析和概率敏感性分析评估结果可靠性。结果 在20~59岁人群HCV检测有成本效果,在40~49岁年龄组进行HCV检测成本效果最佳。20~59岁年龄组人群HCV检测策略与未HCV检测策略比较,增量成本为161.24元/人,增量效用为0.003 6质量调整寿命年(QALYs)/人,ICER为45 197.26元/QALY,ICER小于意愿支付阈值,具有成本效果。各年龄组人群HCV检测策略与未HCV检测策略比较,ICER为42 055.06~53 249.43元/QALY,NMB为96.52~169.86元/人,其中40~49岁年龄组的ICER最低,NMB最高。单因素敏感性分析结果显示,贴现率、丙肝抗体(抗-HCV)检测成本、人群抗-HCV阳性率和直接抗病毒药物治疗成本对经济学评价影响较大,但改变参数取值,结论不变。概率敏感性分析结果表明模型分析结果稳定。结论 医疗机构探索动员20~59岁普通人群进行HCV检测具有较好的成本效果,以40~49岁年龄组人群的HCV检测成本效果最佳。在我国普通人群中实施HCV检测的“愿检尽检”策略,能降低人群丙肝疾病负担。  相似文献
