RESUMEN

BACKGROUND/AIMS: Liver transplantation offers the only definite cure for cirrhosis but lacking donors is problem. Stem cell therapy is attractive in this setting. In this study, we aimed to explore the safety and efficacy of ultrasound-guided percutaneous portal transplantation of peripheral blood monocyte cell (PBMC) in cirrhotic patients. METHODS: A total of nine decompensated cirrhotic patients were randomized into three groups: group 1 (n = 3) was control group, group 2 (n = 3) received granulocyte-colony stimulating factor (G-CSF) mobilization for 3 days, and group 3 (n = 3) received G-CSF mobilized PBMCs by leukapheresis and PBMC transplantation through ultrasound-guided percutaneous portal vein puncture. Liver function and clinical features were evaluated. RESULTS: At baseline, the Child-Turcotte-Pugh and the model for end-stage liver disease scores were comparable in study groups. Compared with group 1, there was a tendency to improve liver function in group 3 at 6 months after treatment. Treatment was tolerable and no complications were encountered related to the G-CSF mobilization or percutaneous portal administration of PBMCs. Imaging studies showed patent portal veins at the end of the study period. CONCLUSIONS: Autologous PBMC transplantation through ultrasound-guided percutaneous portal vein puncture could be considered as a safe alternative treatment for decompensated cirrhotic patients.

RESUMEN

Fucoidan is a traditional Chinese medicine suggested to possess anti-tumor effects. In this study the anti-metastatic effects of fucoidan were investigated in vitro in human hepatocellular carcinoma (HCC) cells (Huh-7 and SNU-761) under normoxic and hypoxic conditions and in vivo using a distant liver metastasis model involving injection of MH134 cells into spleen via the portal vein. Its ability to protect hepatocytes against bile acid (BA)-induced apoptosis was investigated in primary hepatocytes. Fucoidan was found to suppress the invasion of HCC cells through up-regulation of p42/44 MAPK-dependent NDRG-1/CAP43 and partly, under normoxic conditions, through up-regulation of p42/44 MAPK-dependent VMP-1 expression. It also significantly decreased liver metastasis in vivo. As regards its hepatoprotective effect, fucoidan decreased BA-induced hepatocyte apoptosis as shown by the attenuation of caspase-8, and -7 cleavages and suppression of the mobilization of caspase-8 and Fas associated death domain (FADD) into the death-inducing signaling complex. In summary, fucoidan displays inhibitory effects on proliferation of HCC cells and protective effects on hepatocytes. The results suggest fucoidan is a potent suppressor of tumor invasion with hepatoprotective effects.

RESUMEN

BACKGROUND/AIMS: This study compared the outcomes of patients with small hepatocellular carcinomas (HCCs) who were treated using transarterial chemoembolization (TACE) or radiofrequency ablation (RFA). METHODS: This was a post-hoc analysis of a prospective study that evaluated the diagnostic efficacy of magnetic resonance imaging (MRI) and computed tomography (CT). We analyzed 41 small hepatic nodules in 32 patients that showed typical radiologic hallmarks on both CT and gadoxate-enhanced MRI (typical nodules) and 25 small hepatic nodules from 22 patients that showed atypical radiologic hallmarks on CT and typical radiologic hallmarks on MRI (discrepant nodules). RESULTS: There were no significant differences in the baseline characteristics of the patients with typical and discrepant nodules. Complete response rates 1 month after TACE or RFA were 75.0% (18/24) and 94.1% (16/17; P=0.20), respectively, for the patients with typical nodules and 58.8% (10/17) and 100% (8/8; P=0.05), respectively, for the patients with discrepant nodules. Treatment failure rates after TACE or RFA were 33.3% (8/24) and 5.8% (1/17; P=0.15), respectively, for the patients with typical nodules and 47.0% (8/17) and 0.0% (0/8; P=0.02), respectively, for the patients with discrepant nodules. Among patients achieving complete response, there were no significant differences in the risk of marginal recurrence. CONCLUSIONS: RFA provided higher complete response rates and significantly lower treatment failure rates than TACE for patients with discrepant nodules of HCC. Therefore, a treatment modality such as RFA may be preferable for small HCCs which show discrepancy on two imaging modalities.

RESUMEN

BACKGROUND/AIMS: Protein disulfide isomerase (PDI) has been implicated in the survival and progression of some cancer cells, by compensating for endoplasmic reticulum stress by upregulating the protein-folding capacity. However, its prognostic role in patients with hepatocellular carcinoma (HCC) has not been investigated. METHODS: We collected HCC tissues from 83 HCC patients who underwent surgical resection for an immunohistochemical study of PDI. Overall survival (OS) was measured from the date of surgical resection until the date of death from any cause. Radiological progression was evaluated using the modified Response Evaluation Criteria in Solid Tumors in an independent radiological assessment. RESULTS: PDI expression was found to be increased in human HCC compared to adjacent nontumor tissues. Increased immunopositivity for PDI was associated with a high Edmondson-Steiner grade (p = 0.028). Univariate analysis of patients who had undergone surgical resection for HCC showed that tumor PDI upregulation is a significant risk factor for poor OS (p = 0.016; hazard ratio [HR], 1.980) and time to progression (TTP; p = 0.007; HR, 1.971). Multivariate analyses revealed that high PDI expression was an independent predictor of a shorter TTP (p = 0.015; HR, 1.865) and poor OS (p = 0.012; HR, 2.069). CONCLUSIONS: Upregulated PDI expression is associated with aggressive clinicopathological features of HCC; thus, PDI might serve as an independent prognostic factor and a potential therapeutic target for HCC patients.

RESUMEN

BACKGROUND/AIMS: Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the appropriate treatment for needle-track seeding and its clinical outcome. METHODS: We analyzed the clinical characteristics and treatment outcomes in eight patients who experienced needle-track seeding from HCC after an US-guided procedure (FNAB, PEI, or PTBD) between January 1990 and July 2004. RESULTS: Seven (0.14%) of 5,092 patients who experienced needle-track seeding (2 after PEI, 4 after FNAB, and 1 after PTBD) during the study period and 1 other patient who experienced needle-track seeding recently were recruited for this study. Two of the eight patients underwent mass excision and the other six patients underwent en-bloc wide excision for the needle-track seeding. Tumors recurred in the needle-tracks in both patients who underwent mass excision but not in the six patients who underwent en-bloc wide excision. Mortality occurred in three patients who experienced the recurrence and progression of intrahepatic HCC. CONCLUSIONS: The incidence of needle-track seeding after US-guided procedures in HCC was 0.14%. En-bloc wide excision seems to be the optimal treatment for minimizing the probability of tumor recurrence due to needle-track seeding.

RESUMEN

BACKGROUNDS/AIMS: Hepatic involvement is frequently observed in patients with miliary tuberculosis, but primary hepatic tuberculosis with no clinical extrahepatic manifestations of tuberculosis is uncommon. With the ever-increasing number of immunocompromised patients, it is expected that hepatic tuberculosis will occur more frequently. The aim of the present study was to establish the clinical manifestations and course of the disease. METHODS: From January 1989 to September 2008, 12 patients were diagnosed with hepatic tuberculosis by liver biopsy at Seoul National University Hospital. We retrospectively evaluated their clinical, laboratory, and imaging findings by medical record review. RESULTS: Four patients had primary hepatic tuberculosis, and eight patients had hepatic tuberculosis secondary to pulmonary or miliary tuberculosis. Three patients were immunocompromised, and six patients had no previous medical problem. An elevated serum level of alkaline phosphatase was the most frequently observed finding in laboratory tests. Imaging studies showed variable findings, including hepatosplenomegaly, multiple hepatic nodules, abscess formation, and even normal findings. Ten patients responded to antituberculosis drugs, and two cases with tuberculous liver abscess had persistent disease despite prolonged therapy. CONCLUSIONS: In patients with a protracted illness, hepatosplenomegaly and/or abnormal liver function tests, hepatic tuberculosis should be suspected, even in healthy young patients or patients with normal imaging findings. Patients with tuberculous abscess formation tend to respond poorly to antituberculosis therapy, and surgery could be considered in these patients.

RESUMEN

OBJECTIVE: The specific activity of lactase-phlorizin hydrolase (LPH) is very high at birth and sharply declines after weaning, producing lactose intolerance. The prevalence of lactose intolerance is up to 85% in Korean adults. Molecular basis of the regulatory mechanisms responsible for the decline of LPH specific activity is still unknown. In order to elucidate the molecular mechanisms regulating the LPH expression during development, LPH specific activity and mI4NA level of Korean fetal and adult intestines were compared. METHODS: 20 fetal small intestines (16-27 weeks) were obtained during therapeutic abortion and were divided into 3 equal length. 20 adult jejunal tissues were obtained from patients without small intestinal disease during laparotomy. Mucosal homogenates were prepared for dissacharidases specific activities measurement and total RNA was extracted for northern and slot hvbridization. LPH mRNA level was measured by laser densitometer. RESULTS: LPH specific activities of proximal, middle and distal portion of fetal intestines (n=20) were 36.2 +/- 22.5, 38.6 +/- 23.2 and 23.2 +/- 19.9 mu/mg protein, respectively. LPH specific activity of adult jejunum (n=8) was 5.9 +/- 1.8 mu/mg protein and significantly (p<0.05) lower than those of fetal intestines. However, there was no significant difference in sucrase and trehalase specific activities between fetal intestines and adult jejunum. Although LPH specific activity of adult jejunum was lower than those of fetal intestines, LPH mBNA level of adult jejunum was as high as those of fetal intestines. CONCLUSION: These results show that LPH specific activity and mRNA level do not parallel, indicating the posttranscriptional control of fetal development of LPH expression.

RESUMEN

OBJECTIVES: Recently, incidence of Crohn's disease appears to increase in Korea rapidly. To know the current status of Crohn's disease and to disclose characteristic clinical features in Korea, we performed this study. METHODS: We retrospectively reviewed medical records of 117 cases of Crohn's disease registered in Seoul National University Hospital spanning between 1975 and 1996. RESULTS: The number of the annually diagnosed cases has increased upto 10-folds since 1987 than before. The male to female ratio was 1.6 : 1 and the mean age of onset was 22. With regard to location, small intestinal disease was 23%; colonic, 21%; and mixed, 56%. Abdominal pain (97%) was a major symptom, and weight loss (88%), diarrhea (85%), and arthralgia (12%) followed it. However, other extraintestinal manfestations were very rare. Forty five percent of cases had a history of anti-tuberculous medication. Medical treatment was applied in 73% at the time of diagnosis; the outcomes of medical treatment were improvement (81%), switch to operation (9%), stationary (9%) and death (1%). Short- term outcome was worse in cases with internal fistula and elevated ESR. Symptomatic cumulative relapse rates were 20% in 1 year, 34% in 2 years, and 62% in 5 years. In view of long-term course, remission was in 17%; low-grade symptom, 31%; and actively alternating relapse-remission, the rest. CONCLUSION: Crohn's disease in Korea seemed to be apparently increasing. The extraintestinal manifestations and rectal involvement were rare as compared with previous reports of Western countries. Forty five percent of cases had history of antituberculous medication under the impression of intestinal tuberculosis at initial diagnosis.

RESUMEN

One hundred and sixteen Korean adults with biopsy-proven acute viral hepatitis were studied to determine the etiology and the outcome of the disease using paired sera obtained during acute and convalescent phases. The prevalence of acute viral hepatitis A, B, D and non-A non-B were 3.4%, 60.3%, 0.9% and 35.3%, respectively: hepatitis B virus infection was the most common cause and the hepatitis D virus superinfection was almost negligible. Only eleven (26.8%) of 41 patients with AVH NANB were negative for all serological markers of HBV. The rest (73.2%) were positive for at least one HBV marker: HBsAg was positive in 31.7%. Therefore, the presence of HBV serologic markers in the sera does not exclude the diagnosis of AVH NANB in Korea. In patients with acute viral hepatitis B, 27% remained positive for HBsAg. Chronic hepatitis developed in 12.8% and 17% patients with acute hepatitis B and non-A non-B, respectively. Progression to chronic hepatitis in patients with acute viral hepatitis B and non-A non-B occurred more commonly, although statistically not significant, in male sex and in patients who did not have clinical jaundice during the acute phase and who showed bridging necrosis in their liver biopsies. Age did not influence the progression to chronic hepatitis.

RESUMEN

The rate of HBV DNA integration into the genome of hepatocellular carcinoma (HCC) cells varies greatly among HCC tissues from different geographical districts. Because of the potential etiological significance of identifying HBV DNA integration in HCC tissues from Korea, we investigated 13 aseptically obtained HCC surgical specimens by Southern blot analysis. Among 13 HCCs, eight (61.5%) contained integrated HBV DNA. Of eight HBsAg-positive patients, six (75%) had integrated HBV DNA in their HCCs while two (40%) out of five HBsAg-negative patients had integrated HBV DNA. Those two HBsAg-negative patients with integrated HBV DNA were all anti-HBs-positive. However, it was not demonstrated in the patient without any HBV serological markers. These findings highly suggest a prominent etiologic role of HBV in the development of HCC. On the other hand, it also strongly favors a multifactorial etiology of human HCC in korea.

RESUMEN

Primary biliary cirrhosis, a chronic, progressive, and often fatal cholestatic liver disease, is characterized by destruction of intrahepatic bile ducts, portal inflammation and scarring, and the eventual development of cirrhosis and liver failure. We reviewed four cases of primary biliary cirrhosis primarily suspected with peritoneoscopic liver biopsy specimens. All patients were female and their age ranged from 29 to 50 years(median age: 43.8 years). Presenting symptoms were typically pruritus and/or upper abdominal discomfort. On physical examination, interus was presented in 3; hepatomegaly in 3; chronic liver disease stigmata in one. Co-existing autoimmune diseases such as Hashimoto' thyroiditis and Sjoegren' syndrome were found in 2 cases. Biochemical tests of liver function revealed a cholestatic pattern. An antimitochondrial-antibody test was positive in 2 out of 3 patients(75%). Increase levels of serum immunoglobulins, especially of IgM, were evident in 3 cases. Histologic staging(Ludwig et al.) disclosed stage I lesion in one, stage III in two, and stage IV in the remaining one.

RESUMEN

OBJECTIVES: patients with HCV-associated liver cirrhosis had greater risk of hepatocellular carcinoma(HCC) than patients with HRV-associated in areas pirevalent for HCV infection. However, the relative risks of. HBV and HCV for HCC have not been investgated in an HBV-endemic area. The piresent study was designed to study prospectively the relative risk of HBV and HCV for HCC In korea. An HBV- endemic, area. METHODS: We enrolled 373 patien ts with liver ciirrhosis who had experienced thc esophageal variccal bleeding and had been treated by endoscopic injection sclerothenpy, and survived more than 3 months. They were devided into three grourp 1) 245( 65.7%) patients who were positive for HBsAg but nagative for anti- HCV were in HBV group 2) 48 (l2.9'% ) who were negative for HBsAg but positive for anti-H C V were HCV group, and, 3)80 (21.4%) were negative for both were NBNC group. The duta were analyzed stalistically using Kaplan-Melermethod and COX proportional-hazzards regression analysis. RESULTS: During the mean follow-up period of 3.4 years. 68(18.2 %) patients developed HCC. The cumulattive incidence of HCC. Among all patients was 25.4 % during the first 5 years: the incidences in each HBV. HCV and NBNC group during, the first 3 years were 18.3%, 22.0%, and 5.6%. Respectively and those during the first 6 years were 34.7%, 54.8%, and l7.0%, respectively. By univeriate analysis age older than 50 yearser and initial serum a-PF level higher than 5ng/ml also appered to be predictors of grealer risk for the development of HCC. By multivarite analysis. HlBsA g positivity, anti-HCV positivily, old age, and male sex were independent risk factors for HCC. CONCLUSION: We showed for the first time by a prospective study that anti-HCV positive cirrhotic patients had no less or even greater risk I or the development of HCC. Than HBsAg-positive paticnl seven in in HBV-endemic korea as they had in HCV-endemic area such as Japan and Italy.

RESUMEN

BACKGROUND/AIMS: Lens culinaris agglutinin-A reactive alpha-fetoprotein (AFP L3) has been reported to be highly specific for the diagnosis of hepatocellular carcinoma (HCC). The present study was to evaluate the clinical usefulness of AFP-L3 for the diagnosis of HCC in the patients either with chronic liver disease or with HCC in complete remission who showed significant increment of serum AFP level and no mass lesion in the liver on ultrasonography. METHODS: A total numer of 34 patients (24 with chronic liver disease, 10 with HCC in complete remission) were enrolled, who showed significant increment of serum AFP level and no mass lesion in the liver on ultrasonography. Serum AFP L3 levels were analysed by AFP differentiation kit L. Abdominal spiral CT or ultrasonogram was performed at 1-3 month intervals and all of the patients were followed up for more than 6 months. RESULTS: Among 24 patients with chronic liver disease, two were positive (higher than 15%) for AFP L3; however, HCC was not detected in these patients, while HCCs were detected in two of 22 patients negative for AFP L3 during followe-up. Eight of the 10 patients with HCC in complete remission were positive for AFP L3; recurrent HCCs were detected in 7 of those 8 patients as well as in the rest 2 patients negative for AFP L3 during follow-up. The overall sensitivity and specificity of AFP L3 measurement for the detection of HCC within 6 months of follow-up were 63.6% and 87.0%, respectively. The positive and negative predictive value for HCC in patients with chronic liver disease were O% and 90.9% and for recurrent HCC in HCC patients in remission were 87.5% and ON, respectively. CONCLUSION: The measurement of AFP L3 is suggested to be useful for the diagnostic strategy in patients either with chronic liver disease or hepatocellular carcinoma in complete remission, who showed progressive increment of serum AFP level and no mass lesion in liver on ultrasonogram.

RESUMEN

OBJECTIVES: Chronic HBsAg carriers are the principal source of infection for other susceptible people, and are themselves at high risk of developing serious liver diseases. In Korea, it has been estimated that 65-75% of the HBsAg positives remained as persistent carriers. Additionally, familial clustering of HBV infection has frequently been observed among carriers. Some would become progressive, chronic hepatitis patients, and others would not. The aim of this study was to evaluate the association between various factors, such as the duration of infection, type of virus, mutation of precore/core region in HBV, major histocompatibility class-I, and developing chronic liver diseases among familial HBV carriers. METHODS: Chronic carrier status was identified by repeated serological tests for HBsAg at intervals of six months or more. A familial chronic carrier was defined when the disease was observed in a family member over two generations. Two families were recruited, among which a total of 20 chronic HBsAg carriers(11 carriers in No.1, and 9 in No.2 family) were identified. Data on the general characteristics and liver disease status were collected. Identification of the HBV-DNA was successful only for 13 subjects among the 20 carriers. Analysis of viral DNA in terms of subtype, pre-core and core region mutations was carried out. The type of major histocompatibility class-I for the 13 subjects was also analysed. RESULTS & CONCLUSIONS: Seven of 10 chronic HBV carriers of the 1st generation and one of 10 of the 2nd generation were clinical patients with chronic hepatitis, the others, three of the 1st and nine of the 2nd generation, were asymptomatic carriers. This data indicates that the duration of HBV carriage is one of the major factors for disease severity. The subtype of HBsAg analysed using HBV-DNA identified in 13 carriers were adr, and the pattern of precore nonsense mutation in HBV-DNA was identical among family members, which means that the same virus strains were transmitted between the family members. The association between the precore or core mutations in HBV-DNA and the disease severity was not observed. While it was suggested that a specific type of MHC class-I may be related to disease progression.

RESUMEN

BACKGROUND/AIMS: Imrnortalized human fetal liver cell lines established by transfecting simian virus 40 T gene wae found to lose differentiated liver cell functions in successive long-term culture. Butyrate, known as a differentiation-promoting agent for a variety of cancer cell lines, is produced in the colon by bacterial flora and selectively transported into the liver though the portal blood flow. Therefe, butyrate might play a role in the maintenance of differentiation in hepatocytes in vivo. In thepresent study, the effects of butyrate on cell growth and differentiation in human fetal liver cell lines was investigated. METHODS: Human fetal liver cell lines imrnortalized by SV 40 T antigen were treated with sodium butyrate (1mM), and cell growth rate after butyrate treatment were nmsured by the number of viable cells, determined by trypan blue dye exclusice method. The effects of sodium butyrate on the hepatocyte-specific differentiatian were assessed by albumin and alfa-fetoprotein (AFP) mRNA expression, analyzed using reverse-transcription polymerase chain reaction, and were also by the increment of albumin secretion into culture media, determined by a competitive inhibition ELISA. RESULTS: Treatment with sodium butyrate resulted in a cessation of cellular proliferation and alterations in cellular morphology (increased cell size and polygonal change in shape). The level of albumin mRNA after sodium butyrate treatment was elevated by about two times as compared to that of control. In contrast, AFP mRNA expression were dennstrated neither before nor after sodium butyrate treatment. The average amount of albumin released in the medium was less than 6pghnl/10'cells/2days in the absence of sodium butyrate, and increased to 17 p g/ml/10'cells/2days at day 2, 21ugfml 10'cells/2days at day 4 in the presence of sodium butyrate, and these levels thereafter were over 10 times higher than that in the absence of sodium butyrate until day 10. CONCLUSION: These mults indicate that treatment of immcetalized fetal liver cell lines with butyrate leads to inhibition of cellular proliferation and promotion of adult hepatocyte-specific differentiation.

RESUMEN

A case of hepatocellular carcinoma (HCC) complicating with secondary biliary cirrhosis due to intrahepatic bile duct growth of the tumor is presented. The patient was 34 years-old male who had been suffered from right upper quadrant pain with intermittent fluctuating jaundice for 4 months. Left lobectomy specimen contained a single, 4 cm sized, relatively well circumscribed and partly protruding nodular HCC in the medial seqment of left lobe. It compressed the left hepatic duct, and the intra and extra-hepatic ducts were completely plugged with tumor casts (extending to the common bile duct at the operating table). Remaining hepatic parenclyma was the seat of advanced secondary biliary cirrhosis in which were abundance of HBsAg-containing hepatocytes possibily representing a HBsAg carrier status. Biliary cirrhosis in HCC is an extremely rare manifestation, reflecting the delayed adequate clinical procedure by unusual pattern of obstructive jaundice. In such a case presenting as persisting and fluctuating obstructive jaundice in HCC, an intrabile duct tumor growth should be suspected.

RESUMEN

The Duodenal diverticulum is the rare cause of the common bile duct obstruction. We experienced a case of the diverticulum of the second portion of duodenum in a 59-year-old male, who complained recurrent attacks of right upper abdominal pain and fever since 16 months prior to admission. Duodenoscopic finding and UGI study revealed a typical duodenal diverticulum just side to the papilla of Vater. Diverticulectomy and cholecystectomy was performed and after than, he has been free front above mentioned symptoms. We reported a case of duodenal diverticulum which caused recurrent common bile duct obstruction.
