Abstract

Drug-induced tubulointerstitial nephritis is one cause of acute kidney injury. Although traditional remedies have been widely used in South Korea, Dioscorea quinqueloba-induced tubulointerstitial nephritis has not been reported in the general population. A 72-year-old male patient was transferred to our hospital with pulmonary edema, oliguria, decreased mentality, severe generalized edema after taking D. quinqueloba 25 days ago. His initial lab findings showed a blood urea nitrogen level of 43.4 mg/dL, a creatinine level of 5.3 mg/dL. Urinalysis revealed SG (1.015), blood (many), protein (++) and WBC (0-3/HPF). Kidney biopsy demonstrated severe mononuclear cell infiltration into the renal interstitium with mild tubular atrophy. Aggressive renal replacement therapy and supportive care resulted in gradual restoration of his renal function. This case implies that D. quinqueloba may be one cause that induces tubulointerstitial nephritis in some patients.

환자는 집에서 단풍마로 담근 술을 복용한 이후 전신부종, 호흡곤란, 의식저하, 요량감소를 주소로 본원으로 전원되어 왔다. 혈액 검사에서 혈청크레아티닌은 5.3 mg/dL로 증가되어 있었고 소변 검사에서 요단백 2+, 적혈구 many/HPF, 백혈구 0-3/HPF이었다. 지속적 신대체 요법과 혈액투석 치료가 시행되었고 점차로 양호한 경과를 보여 입원 27일째 시행한 신조직 검사에서 세뇨간질성 신염 소견을 확인하였다. 세뇨간질성 신염의 발생 기전은 아직은 명확하지 않고 다양한 원인으로 인해 발생할 수 있으며 적극적인 치료가 필요하다.
