慢性肝炎的定义存在些问题。根据目前分类,病程超过半年(也有人主张一年)即为慢性肝炎。以前这种分类主要用于选择抗炎(免疫抑制)治疗的病人。由各种病因包括乙型肝炎引起的下述各型肝炎均符合这一定义。1.长期轻度小叶病变型常伴有修复过程和含色素的巨噬细胞,转氨酶有波动性,但最终恢复正常,无远期后遗症。2.在实质细胞和汇管区有持续的急性病毒性肝炎样表现(慢性小叶性肝炎),最后可不经治疗而消退,留有不明显的疤痕。
The definition of chronic hepatitis has some problems. According to the current classification, duration of more than six months (some people claim that one year) is chronic hepatitis. This classification was mainly used to select anti-inflammatory (immunosuppressive) treatment of patients. The following types of hepatitis caused by various causes, including hepatitis B, are in line with this definition. 1. Long-term mild lobular disease is often accompanied by repair processes and pigment-containing macrophages, transaminases are volatile, but eventually return to normal without long-term sequelae. 2. In patients with persistent acute viral hepatitis-like manifestations (chronic lobular hepatitis) in parenchymal cells and portal area, they eventually regress without treatment leaving unidentified scars.
