Severe Nephritic-nephrotic Syndrome with Small Bowel Perforation in a Child with $Henoch-Sch\ddot{o}nlein$ Purpura

[ $Henoch-Sch\ddot{o}nlein$ ] Purpura(HSP)는 피부, 관절, 위장관 및 신장 등에 존재하는 소혈관을 침범하는 혈관염으로 보통은 저절로 호전피지만 신장과 위장관에 심각한 합병증을 일으키기도 한다. 또한 신장 침범이 있으면 예후가 좋지 않으며 위장관 천공은 드물게 나타나는 합병증으로 수술로 교정 후 예후는 양호하다. 저자들은 신염-신증후군과 동시에 소장 천공이 나타난 드문 사례를 경험하였기에 이를 고찰과 함께 보고하는 바이다.

[ $Henoch-Sch\ddot{o}nlein$ ] Purpura(HSP) is a form of vasculitis that typically affects small arteries in the skin, joints, intestinal tract and kidneys. It usually resolves spontaneously but sometimes can cause serious problems in the kidneys and intestinal tract. A 6-year-old girl with purpura, arthralgia and abdominal pain for 2 weeks was admitted. She also showed gross hematuria, generalized edema and decreased urine output. Blood pressure was in the upper normal range. Initial laboratory findings showed hypoalbuminemia, hyperlipidemia, microhematuria and nephrotic-range proteinuria(27.2 g/day). Initially, she was treated with pulse methylprednisolone, azathioprine, albumin and furosemide. Her renal biopsy revealed diffuse mesangial proliferation with strong IgA deposition. There were no crescents. On the third hospital day, she complained of severe abdominal pain and free peritoneal air was seen on abdominal X-ray. Primary repair of small bowel was performed and two pin-point sized holes were found. One week later, she still showed heavy proteinuria. Therefore, we added an ACE inhibitor and dipyridamole, and changed azathioprine to cyclosporine. One month later, the urine protein/creatinine ratio was decreased to 17.8 from 57, but heavy proteinuria has been still persisted. Here we report a rare case of a patient with HSP who had both severe nephrritc-nephrotic syndrome and small bowel perforation.
