一般认为链球菌感染后急性肾小球肾炎(PSAGN)的预后良好,尤以儿童,慢性转归并不多见。但晚近有人对儿童的PSAGN在温带和热带是否有良好预后提出了疑问,一些作者对成人的观察也提示大多数PSAGN的成人病例有持久性的肾脏损害。为了探讨其慢性转归,作者对760例临床恢复的PSAGN病例进行了2～6年的随访。 Generally believed that the prognosis of acute glomerulonephritis (PSAGN) after streptococcal infection is good, especially in children, chronic outcome is rare. However, recent questions have been raised about whether children with PSAGN have a good prognosis in temperate and tropical regions. Some authors’ observations of adults also suggest that most adult cases of PSAGN have persistent kidney damage. In order to investigate its chronic outcome, the authors followed 760 patients with clinically recovered PSAGN for 2 to 6 years.
