梨形蟲症併發吸收不良症侯羣：一病例報告

梨形蟲症在英美是常見的原蟲寄生蟲病，感染後可能出現腹瀉、腹漲、嘔吐等症狀，也可能無症狀。若經過長時間未診斷治療，可能會出現吸收不良症候羣。一個智能不足的9歲女童，由於全身水腫，嘔吐5-6天而住院，實驗室檢查白蛋白僅有2.3g/dl，無蛋白尿，糞便量極多而呈撲鼻惡臭。以福馬林一乙醚法無法檢出寄生蟲，施行內視鏡檢查並抽出腸液在顯微鏡下檢查，證實有梨形蟲的滋養體，以metronidazole 250mg每日服用三次，治療7天之後，水腫逐漸消失，白蛋白及膽固醇恢復正常，大便量減少很多。因梨形蟲症併發吸收不良症候羣在台灣尚未有人報告，故在此提出報告。

A 10-year-old mentally retarded girl was sent to our hospital due to generalized edema, vomiting and poor appetite for several days. Serum albumin level was low, but no proteinuria was detected. Her stool was bulky and foul. Stool examination for parasite with formalin-ether concentration method revealed negative result. Trypsin activity test of stool revealed low trypsin activity as compared with normal specimen. Daily fecal fat exceded upper normal limit. The diagnosis of giardiasis was confirmed by duodenal juice examination. Intestinal histology revealed mild shortening of the viii with increased mononuclear cell infiltration in the lamina propria. The daily stool amount decreased markedly after treatment with metronidazole 250mg three times a day for 7 days. The edema subsided during the treatment. Serum albumin bevel returned to normal after the treatment. Giardiasis with malabsorption syndrome has often been overlooked in Taiwan. It is advised that in case of malabsorption syndrome giardiasis should be included in the list of differential diagnosis.
