9治疗的总体目标
慢性乙型肝炎治疗的总体目标是:最大限度地长期抑制或消除HBV,减轻肝细胞炎症坏死及肝纤维化,延缓和阻止疾病进展,减少和防止肝脏失代偿、肝硬化、HCC及其并发症的发生,从而改善生活质量和延长存活时间。 相似文献

随着分子生物学、免疫学的不断进步,国内在针对乙型肝炎的基础、临床研究都取得了较大的成果,但是临床应用价值仍然不甚令人满意。目前慢性乙型肝炎的治疗目标应该是,最大限度地抑制或清除HBV,减轻肝细胞炎症坏死及其所致的肝纤维化,延缓疾病进展。为了探索一条治疗时间短,又能达到治疗目标的方法,近3年来,我们用拉米夫定、干扰素(INF)、胸腺肽α1(Tα1)序贯治疗了64例HBeAg阳性的慢性乙型肝炎患者,现将资料完整的、完成了全疗程的、并且随访1年以上的病例报告分析如下。 相似文献

全球感染乙型肝炎的人数近20亿,其中3.5亿呈慢性感染状态,约占全人口数的5%。我国是一个乙肝高度流行的国家。我国一般人群乙肝表面抗原携带率高达9.09%,远高于欧美、日本等国。随着经济的发展、医疗卫生事业的进步,我国民众普遍关注乙肝病毒慢性感染状态的治疗问题。但限于科技发展的水平与认识的局限,我国慢性乙肝的防治极不规范。尤其是面对大量慢性乙肝病人的基层医务人员常常无所适从,大量慢性乙肝的病例没有得到现代科技事实上已经可以提供的有效治疗。 相似文献

Delta infection was investigated in patients with chronic viral hepatitis by means of detecting antibodies to the delta agent in the patients' blood with the use of radioimmunoassay. It was demonstrated that chronic viral hepatitis B is often (in 44.5% of cases) associated with delta infection and takes a course similar to that of chronic hepatitis A. In this case demonstrable liver injury is observed, which is supported by the clinical, biochemical and morphological findings. 相似文献

As research continues to define the optimal management of chronic hepatitis B virus (HBV) infection, clinicians must deal with a number of yet unresolved issues: Should we treat all patients with HBV infection to prevent liver cancer, even if they have no evidence of active disease? Which is the best treatment strategy? What do we do with patients who develop resistance to our current drugs? Should we treat patients with HBV infection who have already developed cirrhosis? 相似文献

A study was made of latent hepatic diseases in university students. 1.4% to 1.6% of the students were positive for hepatitis B surface antigen (HBsAg), and 10.3% for anti-HBs. Of 28 students with HBs-antigenemia, 2 had chronic persistent hepatitis, and 3 minimal hepatitis, 23 being healthy carriers. Hepatitis B e-antigen (HBeAg) was detected in 44% of the students with HBsAg, and anti-HBe in 13%. Anti-HBe was significantly more frequently found in female students with HBsAg than in male students. Though most of the students with HBsAg had high titer of antibody to hepatitis B core antigen (anti-HBc), there were a small number of cases showing low titer. HBsAg and anti-HBs was detected in the same serum specimens of 2 carrier students. Liver damage was also found in 3 students without HBs-antigenemia. 相似文献

Current therapies for chronic viral hepatitis, autoimmune "lupoid" chronic active hepatitis, and drug-induced chronic hepatitis are discussed in the context of recent advances in our understanding of the pathophysiology of chronic active liver disease. Accurate diagnosis is the cornerstone of proper treatment; the limitations and pitfalls of conventional techniques are discussed. Current theories of the pathogenesis of chronic hepatitis B are reviewed to provide a framework for the use of antiviral drugs. Data from the early results of therapy with adenine arabinoside, acyclovir, and immunomodulatory agents are reviewed, and the theoretical basis for the use of alpha-interferon as well as preliminary data supporting its efficacy is presented. Strategies for the treatment of chronic delta hepatitis and chronic non-A, non-B viral hepatitis are discussed as well. The immunological changes associated with autoimmune chronic active hepatitis are described to help define those patients with chronic active hepatitis who are likely to respond to immunosuppressive therapy. The recognized hazards of long-term corticosteroid therapy are indicated and guidelines for the management of these patients are suggested. Chronic drug-induced liver disease will usually improve with cessation of the offending agent. An approach to the patient with suspected drug-induced chronic hepatitis is indicated. Finally, the role of liver transplantation is mentioned as the ultimate treatment modality available for endstage liver disease. 相似文献

The most common chronic bloodborne infection in the United States, hepatitis C virus (HCV) is the most frequent reason for liver transplantation. Unfortunately, most infected individuals don't realize they're HCV positive and only discover the disease after severe liver damage has occurred. Here, update your knowledge on the epidemiology, transmission and risk factors, diagnosis, clinical presentation, and management of chronic HCV. Insight on counseling and quality of life issues for infected patients is also included. 相似文献

Chronic hepatitis can be caused by a variety of viruses or therapeutic agents, but in about 80% of cases, the cause is unknown. Distinguishing between chronic persistent and chronic active hepatitis is of primary importance in diagnosis and treatment. Percutaneous liver biopsy is necessary to make the distinction. In most cases, chronic persistent hepatitis does not necessitate specific therapy. Chronic active hepatitis responds to a wide range of therapeutic options: corticosteroids, immunosuppressants, antivirals, and immunostimulants. Prognosis depends on the risks and advantages of therapy as well as the severity and cause of the disease. 相似文献
