59세 여자가 복부 통증을 주소로 내원하였다. 복부 전산화 단층촬영에서 담관 결석이 의심되는 병변이 발견되었다. 내시경역행담췌관조영술을 하는 중에 간디스토마 성충이 배출되었다. 대변과 혈청에서 간디스토마 충란과 항체가 각각 발견되어 간디스토마 감염증으로 진단하였다. 내시경 시술과 구충제를 복용 후 증상은 서서히 호전되었다. 환자는 간디스토마 비유행지역에 거주하였고 날 것이나 덜 익힌 민물생선을 섭취한 기왕력이 없었다. 대한민국은 간디스토마 유행지역에 속하며 사람들은 조리기구 등을 통한 간접 접촉을 통해서 감염될 수 있다. 그러므로 대한민국에서 담관 질환이 있는 환자들을 진료할 때 간디스토마 감염의 가능성을 고려하여야 한다. 우리는 문헌고찰과 함께 임상 증례를 보고한다.

DNA methylation is the most common and well-characterized epigenetic change in human cancer. Recently, the association between GATA-binding protein 5 (GATA5) methylation and carcinogenesis of various types of tumors was investigated. The aim of the present study was to evaluate the effect of GATA5 methylation status on clinicopathological features and prognosis in primary non-muscle invasive bladder cancer (NMIBC) patients with a long-term follow-up period. The GATA5 methylation status was determined for 171 human bladder specimens (eight normal controls [NCs] and 163 primary NMIBC patients) using quantitative pyrosequencing analysis. The primary NMIBC tissues were obtained from patients who underwent transurethral resection (TUR) for histologically diagnosed transitional cell carcinomas between 1995 and 2012 at Chungbuk National University Hospital. GATA5 methylation was significantly higher in NMIBC patients than in NCs and was significantly associated with higher grade and more advanced stage of cancer. Kaplan-Meier estimates showed significant differences in tumor recurrence and progression according to GATA5 methylation status (each p<0.05). Our results show that increased methylation of GATA5 was significantly associated with not only aggressive characteristics but also poor prognosis in primary NMIBC patients. Alteration of GATA5 methylation might be used as a biomarker for prognosis of NMIBC patients. However, prospective and functional investigations are necessary to clarify the role of GATA5 methylation in future clinical management of patients with NMIBC.
