최근 10년간 소아의 연구균 감염 후급성 사구체 신염에 관한 임상적 연구 = A Clinical Study of Acute PoststreptococcalGlomerulonephritis in Children, from 1994 to 2003

다국어 초록 (Multilingual Abstract)

Purpose : Acute poststreptococcal glomerulonephritis(APSGN) is a common form of glomerulonephritis in children. Most patients recover completely after the acute phase but a few patients have acute complications or progress to chronic renal disease. In recent years, the frequency of APSGN has been was decreasing but is still common in children. So we studied the clinical characteristics of APSGN from 1994 to 2003 and compared it with past studies.
Methods : We studied 105 patients who were diagnosed with APSGN in the Department of Pediatrics, Asan Medical Center between January 1994 and December 2003, with a retrospective chart review.
Results : The mean age was 8.5±2.6 years. The male to female ratio was 2 : 1. Average annual incidence was 10.5±4.9 most patients(60.0 percent) occurred from October to January. Edema was seen in 82 cases(78.1 percent), gross hematuria in 70 cases(66.7 percent), hypertension in 50 cases (47.6 percent) and oliguria in 22 cases(20.9 percent). Microscopic hematuria was seen in 105 cases (100 percent), positive ASO in 99 cases(94.2 percent), proteinuria in 67 cases(63.8 percent) and azotemia in 38 cases(36.2 percent). Serum complement 3(C3) level decreased in 96 cases and returned to normal within eight weeks in 70 patients(75.3 percent). Kidney biopsy was carried out in 22 cases. Most acute symptoms subsided within 2 weeks of onset.
Conclusion : We concluded that there was no significant difference between clinical features of recent and past APSGN in children, and short term prognoses were excellent.

목 적 : APSGN은 소아에서 흔히 볼 수 있는 급성 사구체 신염의 하나로, 대부분의 환자에서 급성기 이후 완전한 회복을 보이지만, 소수의 환자에서는 급성기 합병증으로 사망하거나, 이후에 만성 신부전으로 진행하기도 하는 것으로 알려져 있다. 최근 과거에 비하여 발생빈도가 줄어들었으나, 여전히 소아에서 흔히 볼 수 있는 신질환으로 최근 10년간의 임상 양상을 살펴보고, 과거의 보고들과의 차이를 알아보고자 하였다.방 법 : 1994년 1월부터 2003년 12월까지 서울아산병원 소아과에서 APSGN으로 진단받고 입원 또는 외래 치료를 시행한 105명의 환아를 대상으로 후향적으로 의무기록을 검토하여 연구하였다.결 과 : APSGN으로 진단받은 환아들의 남녀비는 2 : 1이었고, 평균연령은 8.5±2.6세였다. 연평균 발생 비율은 10.5±4.9였고, 연중 발생을 살펴보면 대부분(60.0%)의 환아가 10월에서 1월 사이에 발생하였다. 내원 당시 부종이 82명(78.1%), 육안적 혈뇨 70명(66.7%), 고혈압 50명(47.6%), 핍뇨 22명(20.9%)에서 나타났고, 현미경적 혈뇨 105명(100%), ASO 양성 99명(94%), C3 감소 96명(91.45), 단백뇨 67명(63.8%)에서 나타났고, BUN이 증가한 경우가 38명(26.2%)였다. C3가 감소하였던 96명 중 70명(75.3%)에서 8주째 정상으로 회복되었다. 22명의 환아에서 신장조직 검사를 시행하였다. 급성기 증상은 대부분의 환아에서 1-2주 사이에 소실되었다.결 론:APSGN의 임상양상은 과거의 연구들과 비교하여 큰 차이가 없었고, 급성기 회복률 및 단기예후는 우수하였다.
