Henoch-SchÖnlein (HSP)은 대부분 3-15세의 소아에서 발병하는 모세혈관과 소동맥을 침범하는 원인불명의 전신 혈관염이다. 임상적인 특징 으로는 비혈소판 감소성의 촉지되는 자반, 관절통또는 관절염, 복부통증 그리고 신기능이상을 보인다. 약 25%에서는 자반증없이 첫증상으로 복부 통증이나 관절통을 나타내는 경우가 있으며 이러한 경우에 진단이 어려워지게 된다. 본 예에서는 47세 남자가 내원 10일 전 부터 발생 한 심와부 통증을 주소로 내원하였고 혈청생화학적 검사에서 빌리루빈 상승과 함께 Alkaline phosphase, r-GTP상승이 동반된 담즙정체성 간 염을 보이고 있었다. 하지의 자반증은 입원 4일 후에 발생하였고 이로 인해 진단이 늦어지고 원인불명의 간염을 진단하기 위해 간조직검사까 지 시행한 예이다. 이후 복부 통증과 혈변이 발생하여 상부위장과 대장내시경을 시행하였고 상하부장관에서도 HSP가 침범하였음을 확인하 였다. 또한 혈뇨와 단백뇨도 동반되어 신장조직검사도 시행하였고 신조직검사에서도 IgA의 침착을 확인하여 신장까지 침범하였음을 확인하 였다. 현재까지 간담도계를 침범한 HSP에 대한 예는 성인에서는 보고된 예가 없었다. 다만, 소아의 경우 담관을 침범하여 간경화까지 진행하 였고 이후 간이식 시행한 1예가 있었다. 저자들은 성인 HSP 환자에서 피부 자반에 앞서 복부 통증과 담즙정체성 간염을 첫증상으로 나타낸 1예를 경험하여 이를 보고하고자 한다.

Background and Aims: Hepatitis D virus (HDV) is a defective RNA virus that depends on hepatitis B virus for its replication and represents a severe form of chronic hepatitis. The prevalence varies between different parts of the world. This study aimed to investigate the seroprevalence and clinical features of HDV co-infection in Korea, where HBV infection is endemic. Methods: A total of 1820 sAg positive patients were evaluated. 144 consecutive patients were tested for Ab for HDV. HDV RNA was confirmed by nested RT-PCR and clinical features were eval- uated retrospectively. Results: Of 1820 sAg positive patients, 144 consecutive patients were evaluated for the HDV Ab (7.9%). 11 patients showed HDV Ab positivity and the seroprevalence of HDV is 0.6% among 1820 HBs Ag positive patients in our hospital. The mean age was 40 years old (33-48 years) and 6 were males and 5 were females. Only one patient showed high HBV DNA level more than 105copies/mL. HDV RNA was detected in 4 patients among 7 patients who underwent nested RT-PCR for HDV RNA. Inactive HBsAg carriers, chronic hepatitis B, cirrhosis and hepatocellular carcinoma accounted for 1 (9.1 %), 3 (27.3 %), 4 (36.4 %) and 3 (27.2 %), respectively. Interestingly, all the HDV-positive patients in current study reported the history of residence in North Korea or Mongolia. Conclusions: This study demonstrates that the seroprevalence of HDV infection is very low (0.6%,11/1820) in this single center for last 5 years. But the portion of patients evaluated for HDV is only 7.9 %. In spite of low level of HBV DNA, young age and female sex, significant portion of HDV-positive patients showed ad- vanced liver disease such as liver cirrhosis or hepatocellular carcinoma. So further evaluations are warranted to understand the routes of trans- mission and establish the most effective therapy.
