RESUMO
Background/Aims@#Recent data indicate the presence of liver enzyme abnormalities in patients with coronavirus disease 2019 (COVID-19). We aimed to evaluate the clinical features and treatment outcomes of COVID-19 patients with abnormal liver enzymes. @*Methods@#We performed a retrospective, multicenter study of 874 COVID-19 patients admitted to five tertiary hospitals from February 20 to April 14, 2020. Data on clinical features, laboratory parameters, medications, and treatment outcomes were collected until April 30, 2020, and compared between patients with normal and abnormal aminotransferases. @*Results@#Abnormal aminotransferase levels were observed in 362 patients (41.1%), of which 94 out of 130 (72.3%) and 268 out of 744 (36.0%) belonged to the severe and non-severe COVID-19 categories, respectively. The odds ratios (95% confidence interval) for male patients, patients with a higher body mass index, patients with severe COVID-19 status, and patients with lower platelet counts were 1.500 (1.029 to 2.184, p=0.035), 1.097 (1.012 to 1.189, p=0.024), 2.377 (1.458 to 3.875, p=0.001), and 0.995 (0.993 to 0.998, p>0.001), respectively, indicating an independent association of these variables with elevated aminotransferase levels. Lopinavir/ ritonavir and antibiotic use increased the odds ratio of abnormal aminotransferase levels after admission (1.832 and 2.646, respectively, both p<0.05). The median time to release from quarantine was longer (22 days vs 26 days, p=0.001) and the mortality rate was higher (13.0% vs 2.9%, p<0.001) in patients with abnormal aminotransferase levels. @*Conclusions@#Abnormal aminotransferase levels are common in COVID-19 patients and are associated with poor clinical outcomes. Multivariate analysis of patients with normal aminotransferase levels on admission showed that the use of lopinavir/ritonavir and antibiotics was associated with abnormal aminotransferase levels; thus, careful monitoring is needed.

RESUMO
Background@#Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. @*Methods@#We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. @*Results@#A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. @*Conclusion@#In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.
RESUMO
BACKGROUND/AIMS@#The optimal management of chronic hepatitis B (CHB) patients with partial virologic response (PVR) to tenofovir disoproxil fumarate (TDF) remains unclear. We aimed to evaluate the long-term efficacy of prolonged TDF therapy in treatment-naïve CHB patients with PVR to TDF therapy in real practice.@*METHODS@#We retrospectively investigated the efficacy of prolonged TDF therapy in treatment-naïve CHB patients with PVR to TDF. PVR was defined as a decrease in serum hepatitis B virus (HBV) DNA over 2 logâ‚â‚€ IU/mL from baseline, with detectable HBV DNA by real-time polymerase chain reaction at week 48.@*RESULTS@#We included 232 patients who underwent TDF therapy for over 48 weeks. Forty-two patients (18.1%) showed PVR. In multivariate analysis, hepatitis B e antigen (HBeAg) positivity, and high levels of serum HBV DNA at baseline and week 12 were independent predictive factors for PVR during TDF therapy. Out of 42 patients with PVR, 39 (92.9%) achieved virologic response (VR) during continuous TDF treatment; the cumulative VR rates at 24, 36, and 48 months were 79.8%, 88.2%, and 95.6%, respectively. With an additional 12 months of therapy, VR was achieved in 28/31 (90.3%) patients with HBV DNA < 100 IU/mL, compared to 5/11 (45.5%) patients with HBV DNA ≥ 100 IU/mL, at week 48.@*CONCLUSIONS@#The vast majority of patients achieved VR through prolonged TDF therapy, thus TDF treatment can be maintained in nucleos(t)ide-naïve patients with PVR at week 48, especially in those with low viremia.
RESUMO
BACKGROUND/AIMS@#Previous studies have reported a high rate of sustained virologic response (SVR) and a low rate of serious adverse events with the use of daclatasvir (DCV) and asunaprevir (ASV) combination therapy. We evaluated the efficacy and safety of DCV and ASV combination therapy for patients with chronic hepatitis C virus (HCV) genotype 1b infection in real world.@*METHODS@#We enrolled 278 patients (184 treatment-naïve patients) from five hospitals in Daegu and Gyeongsangbuk-do. We evaluated the rates of rapid virologic response (RVR), end-of-treatment response (ETR), and SVR at 12 weeks after completion of treatment (SVR12). Furthermore, we investigated the rate of adverse events and predictive factors of SVR12 failure.@*RESULTS@#The mean age of patients was 59.5 ± 10.6 years, and 140 patients (50.2%) were men. Seventy-seven patients had cirrhosis. Baseline information regarding nonstructural protein 5A (NS5A) sequences was available in 268 patients. Six patients presented with pretreatment NS5A resistance-associated variants. The RVR and the ETR rates were 96.6% (258/267) and 95.2% (223/232), respectively. The overall SVR12 rate was 91.6% (197/215). Adverse events occurred in 17 patients (7.9%). Six patients discontinued treatment because of liver enzyme elevation (n = 4) and severe nausea (n = 2). Among these, four achieved SVR12. Other adverse events observed were fatigue, headache, diarrhea, dizziness, loss of appetite, skin rash, and dyspnea. Univariate analysis did not show significant predictive factors of SVR12 failure.@*CONCLUSIONS@#DCV and ASV combination therapy showed high rates of RVR, ETR, and SVR12 in chronic HCV genotype 1b-infected patients in real world and was well tolerated without serious adverse events.
RESUMO
Mycoplasma pneumoniae (M. pneumoniae) is a major cause of community acquired respiratory infections. And it also causes a number of extrapulmonary manifestations including cardiovascular, dermatological, musculoskeletal, and hematological systems. But, acute hepatitis without lung involvement is rare in adults. Here, we report a case of 32-year-old man who presented with fever, chilling, myalgia, and headache. Biochemical analysis showed severely impaired liver function and leukopenia. Laboratory tests and liver biopsy demonstrated a hepatocellular pattern of M. pneumoniae-associated acute hepatitis. Clinical symptoms and laboratory parameters are improved rapidly under treatment with macrolide. Therefore, We recommend that phsycians should consider a possibility of M. pneumoniae infection in acute hepatitis without lung and extrapulmonary involvement, when other more frequent causes have been excluded.

BACKGROUND/AIMS: Treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) remains controversial. We compared the outcomes of hepatic resection (HR), transarterial chemoembolization (TACE), and sorafenib therapy as treatments for HCC with PVTT. METHODS: Patients diagnosed as HCC with PVTT between January 2000 and December 2011 who received treatment with sorafenib, HR, or TACE were included. Patients with main PVTT, superior mesenteric vein tumor thrombosis, or Child-Turcotte-Pugh (CTP) class C were excluded. The records of 172 patients were analyzed retrospectively. HR, TACE, and sorafenib treatment were performed is 40, 80, and 52 patients respectively. PVTT was classified as either involving the segmental branch (type I) or extending to involve the right or left portal vein (type II). RESULTS: The median survival time was significantly longer in the HR group (19.9 months) than in the TACE and sorafenib groups (6.6 and 6.2 months, respectively; both p<0.001), and did not differ significantly between the latter two groups (p=0.698). Among patients with CTP class A, type I PVTT or unilobar-involved HCC, the median survival time was longer in the HR group than in the TACE and sorafenib groups (p=0.006). In univariate analyses, the initial treatment method, tumor size, PVTT type, involved lobe, CTP class, and presence of cirrhosis or ascites were correlated with overall survival. The significant prognostic factors for overall survival in Cox proportional-hazards regression analysis were initial treatment method (HR vs. TACE: hazard ratio=1.750, p=0.036; HR vs. sorafenib: hazard ratio=2.262, p=0.006), involved lobe (hazard ratio=1.705, p=0.008), PVTT type (hazard ratio=1.617, p=0.013), and CTP class (hazard ratio=1.712, p=0.012). CONCLUSIONS: Compared with TACE or sorafenib, HR may prolong the survival of patients with HCC in cases of CTP class A, type I PVTT or unilobar-involved HCC.

BACKGROUND/AIMS: The optimal management of patients exhibiting a partial virologic response (PVR) to entecavir (ETV) has not been determined . The aim of this study was to determine the long-term efficacy of prolonged ETV monotherapy in treatment-naive chronic hepatitis B (CHB) patients exhibiting a PVR to ETV therapy. METHODS: This study included 364 treatment-naive CHB patients treated with ETV for > or =48 weeks and who received continuous ETV monotherapy for > or =96 weeks. PVR was defined as a decrease in serum hepatitis B virus (HBV) DNA of more than 2 log10 IU/mL from baseline but with detectable HBV DNA by real-time PCR assay at week 48. RESULTS: Fifty-two of the 364 patients (14.3%) showed a PVR. Among them, 41 patients received continuous ETV monotherapy for > or =96 weeks (median duration 144 weeks, range 96-312 weeks), and 40 of these patients (95%) achieved a virologic response (VR, HBV DNA <20 IU/mL) during prolonged ETV monotherapy (median duration 78 weeks, range 60-288 weeks). The cumulative probabilities of a VR at weeks 96, 144, and 192 from treatment initiation were 78.0%, 92.7%, and 95.1%, respectively. The VR rate was 97.2% (35/36) in HBeAg-positive patients and 100% (5/5) in HBeAg-negative patients. In multivariate analysis, HBeAg positivity (odds ratio [OR], 9.231; 95% confidence interval [CI], 1.03-82.91; P=0.047) and a high baseline HBV DNA level (OR, 0.170; 95% CI, 0.08-0.37; P=0.000) were independently associated with a delayed virologic response. No patient developed genotypic resistance to ETV during follow-up. CONCLUSIONS: Long-term ETV monotherapy is effective for achieving a VR in treatment-naive CHB patients exhibiting a PVR to ETV. HBeAg positivity and high baseline HBV DNA level were independently associated with a delayed virologic response.

Hepatoblastoma usually occurs in children under the age of 2 years, with very few cases reported in adults. We experienced a case of adult hepatoblastoma in a 36-year-old female with chronic hepatitis B . She had experienced sudden onset abdominal pain. Her serum alpha-fetoprotein level was markedly elevated, and abdominal CT showed a 9-cm mass with internal hemorrhage in the right hepatic lobe with hemoperitoneum, so an emergency hepatic central bisectionectomy was performed. The initial histologic examination revealed that the mass mimicked combined hepatocellular carcinoma and cholangiocarcinoma with spindle-cell metaplasia of the cholangiocarcinoma element. Follow-up abdominal CT performed 3 months later showed a 5.5-cm metastatic mass in the left subphrenic area. Laparoscopic splenectomy with mass excision was performed, and hepatoblastoma was confirmed histologically. A histologic re-examination of previously obtained surgical specimens also confirmed the presence of hepatoblastoma. Metastatic hepatoblastoma was found at multiple sites of the abdomen during follow-up, and so chemotherapy with cisplatin, 5-fluorouracil (5-FU), and vincristine was applied, followed by carboplatin and doxorubicin . Despite surgery and postoperative chemotherapy, she died 12 months after symptom onset.

BACKGROUND/AIMS: Obesity increases the risk of colorectal cancer and adenomatous polyp, and one of the underlying mechanisms of this increase is considered to be due to the growth promoting effects of adipokines, such as leptin. In order to investigate this finding, leptin expression in the colonic tissue and blood leptin concentration of the colonic adenoma patients were compared to those of the control group. METHODS: Colonic adenoma tissues were obtained by polypectomy (n=60). In these patients, normal colonic mucosa at remote areas from the polyp was also obtained and blood samples were collected as well. Age and sex matched control subjects were selected among those who showed normal colonic mucosa in health screening colonoscopy (n=60). RESULTS: There was no significant difference in serum leptin concentration between the colonic adenoma patients and control subjects. Leptin expression was noted in 43.3% of the colonic adenomas, but only in 6.7% of normal colonic mucosa from the control subjects (p<0.01). There were ten cases of concurrent adenocarcinoma in situ in adenoma patients, eight cases of which expressed leptin (p=0.01). In adenoma group, leptin expression rate was significantly high in larger adenomas and in obese patients (p<0.05). However, there was no statistically significant relationship between leptin expression in colonic mucosa and serum leptin level. CONCLUSIONS: Leptin expression was more frequently observed in colonic adenomas, especially in larger adenomas associated with adenocarcinoma in situ, but blood leptin level was not related to tissue leptin expression. Leptin expression was more frequently observed in obese patients from the adenoma group. Therefore, leptin may play an important role in colonic tumorigenesis and progression, especially in obese patient.

BACKGROUND/AIMS: Beta-blockers have been used extensively to prevent esophageal variceal (EV) rebleeding in patients with liver cirrhosis. The aim of this study was to compare the rate of EV rebleeding according to the dose of beta-blocker, between maximally tolerable dose (MTD) and low dose (LD) groups. METHODS: A total of 95 patients, who were treated with emergent EV ligation for acute EV bleeding and have since then taken propranolol for 1 month or longer, were enrolled. Forty-nine patients took propranolol at the MTD (154.7 +/- 10.1 mg/day), and 46 patients took propranolol at the LD (39.1 +/- 5.8 mg/day). The end point was occurrence of EV rebleeding. RESULTS: The MTD and LD groups were well matched for age, sex, etiologies for cirrhosis, presence of ascites or encephalopathy, serum creatinine levels, and follow-up periods. The MTD group showed relatively lower Child-Pugh scores, mode for end stage liver disease (MELD) scores, and serum bilirubin, as well as shorter prothrombin time, but a higher dose reduction rate, as compared with the LD group. The rate of EV rebleeding was lower in the MTD group than the LD group (38.8% vs. 67.4%, p = 0.007). In the univariate analysis, the risk factors for EV rebleeding were Child-Pugh classification and dose of propranolol. However, the dose of propranolol was only a significant risk factor for EV rebleeding according to the multivariate analysis. CONCLUSIONS: The effect of propranolol on the prevention of EV rebleeding was superior in the MTD group than in the LD group.

BACKGROUND: Most mutations in the reverse transcriptase (RT) gene of the hepatitis B virus (HBV) are related to resistance to antiviral agents. Cross-sectional studies on the mutations of this gene are rare. Thus, we analyzed the mutation patterns of RT genes and their biochemical parameters. METHODS: From 2009 to 2012, 301 blood specimens from patients with chronic hepatitis B at Daegu Catholic University Medical Center were retrospectively analyzed for the RT gene sequence of HBV, ALT, hepatitis B e antigen (HBeAg), and HBV DNA. The mutation patterns of the RT gene were compared with the biochemical parameters. RESULTS: Of the 301 patients, 100 (33.2%) had no RT gene mutations. The remaining showed the following mutation patterns: rtM204I/V (50.2%), rtL180M (39.2%), and rtA181T/V (19.6%). Combined mutations were found in 146 cases (48.5%). Of these, the combination of amino acid changes at rt180+rt204 (49.3%) was most frequently detected, followed by rt181+rt236 (11.0%) and rt173+rt180+rt204 (9.6%). In the mutated group, HBV DNA and HBeAg positive rates were significantly higher (P<0.05 for both). Phenotypic analysis showed that lamivudine resistance was most frequently detected (34.6%), followed by adefovir resistance (15.6%). Multidrug resistance was detected in 48 cases (15.9%). The adefovir-resistant group had a higher proportion of cases with HBV loads greater than 2,000 IU/mL. CONCLUSIONS: We found correlations between the mutation status of the RT domain and biochemical parameters such as HBV DNA and HBeAg positive rate. The presence of RT gene mutations could therefore be utilized to predict clinical status.

BACKGROUND/AIMS: While gastric variceal bleeding (GVB) is not as prevalent as esophageal variceal bleeding, it is reportedly more serious, with high failure rates of the initial hemostasis (>30%), and has a worse prognosis than esophageal variceal bleeding. However, there is limited information regarding hemostasis and the prognosis for GVB. The aim of this study was to determine retrospectively the clinical outcomes of GVB in a multicenter study in Korea. METHODS: The data of 1,308 episodes of GVB (males:females=1062:246, age=55.0+/-11.0 years, mean+/-SD) were collected from 24 referral hospital centers in South Korea between March 2003 and December 2008. The rates of initial hemostasis failure, rebleeding, and mortality within 5 days and 6 weeks of the index bleed were evaluated. RESULTS: The initial hemostasis failed in 6.1% of the patients, and this was associated with the Child-Pugh score [odds ratio (OR)=1.619; P<0.001] and the treatment modality: endoscopic variceal ligation, endoscopic variceal obturation, and balloon-occluded retrograde transvenous obliteration vs. endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt, and balloon tamponade (OR=0.221, P<0.001). Rebleeding developed in 11.5% of the patients, and was significantly associated with Child-Pugh score (OR=1.159, P<0.001) and treatment modality (OR=0.619, P=0.026). The GVB-associated mortality was 10.3%; mortality in these cases was associated with Child-Pugh score (OR=1.795, P<0.001) and the treatment modality for the initial hemostasis (OR=0.467, P=0.001). CONCLUSIONS: The clinical outcome for GVB was better for the present cohort than in previous reports. Initial hemostasis failure, rebleeding, and mortality due to GVB were universally associated with the severity of liver cirrhosis.

BACKGROUND/AIMS: Between endoscopic sphincterotomy (ES) alone and combined endoscopic sphincterotomy and large balloon dilation (ES-LBD) groups, efficacy and long-term complications, difference in biliary stone recurrence rate, and risk factors of stone recurrence were compared. METHODS: Medical records of 222 patients who underwent ERCP for biliary stone removal were retrospectively reviewed. Patients with dilated CBD > or =11 mm and follow-up longer than 6 months were included. RESULTS: There were 101 patients in ES-LBD group and 121 patients in ES group. Mean follow-up duration was 25.0 (6-48) months and 13.0 (6-43) months, respectively (p=0.001). There was no difference in number of ERCP sessions, brown pigment stones, angle between mid and distal common bile duct (CBD angle) <135degrees, and lithotripsy rate. Complete retrieval success rate was excellent in both groups (100% vs. 99%). Early complication rate of ES-LBD and ES alone group was 4 and 4.1%, respectively (p=1.000). One patient in ES-LBD group died from delayed bleeding. Late complication rate was 5.9 and 3.3%, respectively (p=1.000). Stone recurrence rate was 6.9% and 5.8%, respectively (p=0.984). The only Independent risk factor of stone recurrence was presence of periampullary diverticulum. CONCLUSIONS: Late complication and stone recurrence rates were similar between ES-LBD and ES alone groups.

BACKGROUND/AIMS: The effect of entecavir (ETV) in treatment-naive chronic hepatitis B (CHB) is well established. This study aimed to assess the efficacy of ETV treatment at 0.5 mg/day in ETV-switch and ETV-retreatment groups of CHB patients without lamivudine (LMV)-resistance from LMV monotherapy. METHODS: Study subjects included 350 CHB patients who had been treated with 0.5 mg/day of ETV for at least 6 months. Patients were divided into two groups: an LMV-naive group (n = 263) and an LMV-experienced group (n = 87). The LMV-experienced group was further subdivided into an ETV-switch group (n = 43) and an ETV-retreatment group (n = 44) defined by the period between stopping LMV and restarting ETV. RESULTS: There were no significant differences in mean age, sex ratio, prevalence of liver cirrhosis and hepatitis B e antigen (HBeAg) positivity between the LMV-naive and -experienced groups. However, the LMV-naive group had higher aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels and a shorter ETV treatment duration than the LMV-experienced group. There were also distributional differences in the hepatitis B virus (HBV) DNA levels of LMV-naive and -experienced patients prior to ETV treatment. After ETV treatment, there were no significant differences between the two groups in the rates of undetectable HBV DNA at 6, 12 and 18 months; HBeAg loss and seroconversion; normalization of ALT; virologic breakthrough; and ETV-genotypic resistance. Lastly, the effect of ETV did not differ between the ETV-switch and -retreatment groups. CONCLUSIONS: The effect of ETV in the LMV-experienced group without LMV-resistance did not differ from that in the LMV-naive group. Furthermore, there was no difference in the effect of ETV between the ETV-switch and -retreatment groups.

Liver cirrhosis has distortion of the hepatic architecture and the formation of regenerative nodules due to progressive hepatic fibrosis. Treatment of underlying etiology can slow or reverse the progression of liver fibrosis. Early stage is characterized by asymptomatic phase, termed 'compensated cirrhosis' follwed by the development of complications of portal hypertension and/or liver dysfunction, termed 'decompensated cirrhosis'. The quality of life and survival of patients with cirrhosis can be improved by prevention and treatment of these complications. This review discuss the complication and its management in patients with liver cirrhosis.

BACKGROUND/AIMS: Toxocariasis rarely causes a liver abscess. We assessed clinical and laboratory manifestations as well as therapeutic responses in patients with toxocariasis presenting as a liver abscess. METHODS: Fourteen patients with toxocariasis presenting as a liver abscess were analyzed retrospectively. Symptoms, occupational history, dietary habits, contact with pets, allergic disease, peripheral eosinophil count, serum immunoglobulin E (IgE) level, and invasion to other organs were evaluated. After treatment with albendazole, follow-up was conducted with abdominal computed tomography (CT) and the measurement of serum eosinophil and IgE levels. RESULTS: Among 568 patients with a liver abscess, 14 were diagnosed with active toxocariasis. The mean age of the patients was 48 years, and nine (64%) were men. Four (28.6%) patients had pain in the right upper quadrant of the abdomen or epigastric area, one had cough, and the others (64.3%) had no symptom. Pulmonary involvement was noted in five patients and colon involvement in one. Six (42.9%) patients had a recent history of eating raw meat. Initial laboratory findings showed increased eosinophil and IgE levels in all patients. The initial CT showed one or multiple ill-defined, hypodense lesions in the liver. After 1 month of albendazole treatment, eosinophil counts were normalized or had decreased in 13 (93%) patients. On follow-up CT, liver abscesses disappeared within 6 months after therapy in 92% of patients. CONCLUSIONS: Symptoms, laboratory findings, and treatment of a liver abscess caused by toxocariasis differ from those of a pyogenic liver abscess. Early serologic testing may increase diagnostic yield and efficacy of treatment in patients with a liver abscess and peripheral eosinophilia.

BACKGROUND/AIMS: Pegylated interferon (peginterferon) and ribavirin combination therapy is less effective and associated with a higher frequency of serious complications in chronic hepatitis C patients with cirrhosis than in noncirrhotic patients. This study evaluated the efficacy and tolerability of peginterferon and ribavirin treatment in patients with hepatitis C virus (HCV)-related cirrhosis. METHODS: Eighty-six patients with clinically diagnosed liver cirrhosis were treated with either peginterferon alpha-2a (n=51) or peginterferon alpha-2b (n=35) plus ribavirin. The sustained virologic response (SVR) and adverse effects were analyzed retrospectively. RESULTS: Of the 86 patients (55 males), 48 patients (55.8%) had HCV genotype 1 infection and 38 (44.2%) had genotype non-1 infection. The overall SVR rate was 34.9% (30/86), and the rates of SVR in the genotype 1 and non-1 patients were 20.8% (10/48) and 52.6% (20/38), respectively. The multivariate analysis revealed that having HCV genotype 1 (P=0.003) and high baseline viral load (>8.0x10(5) IU/mL, P=0.012) were the independent predictive factors for SVR failure. In 20.9% (18/86) of the patients, treatment was not completed due to adverse events (27.8%), loss to follow-up (50.0%), and other reasons (22.2%). CONCLUSIONS: Peginterferon and ribavirin combination therapy was relatively effective and feasible for clinically diagnosed HCV patients, especially in those with genotype non-1 infection and low baseline viral load.
