RESUMEN

AIM: Chronic liver insufficiency is often associated with changes in amino acid metabolism. We evaluated whether change in serum amino acid concentrations had prognostic value among patients with liver cirrhosis. METHODS: This retrospective study evaluated 158 patients who had been hospitalized with cirrhosis. Baseline serum concentrations of branched-chain amino acids (BCAAs) and tyrosine, as well as the BCAA-to-tyrosine ratio, were evaluated. Cox proportional hazards analysis was used to calculate the hazard ratios for factors that were associated with mortality or liver transplantation. RESULTS: Among the 158 patients, baseline measurements showed decreased serum BCAA concentrations for 59 patients (37.3%), elevated serum tyrosine concentrations for 80 patients (50.6%), and a decreased BCAA-to-tyrosine ratio for 114 patients (72.2%). During a median follow-up period of 3.0 years, death or liver transplantation occurred at a rate of 0.136 cases/1 person-year. Multivariable analysis showed that transplant-free survival was independently predicted by older age, male sex, comorbid hepatocellular carcinoma, Child-Turcotte-Pugh score, and serum tyrosine concentration. Receiver operating characteristic curve analysis showed that a serum tyrosine concentration of >110 µmol/L was the optimal cut-off value for predicting transplant-free survival (adjusted hazard ratio 1.89, 95% confidence interval 1.15-3.11, p = 0.012). Kaplan-Meier analysis showed a significant difference in the 5-year transplant-free survival probability between patients with high and low serum tyrosine concentrations (42.1% vs. 60.7%, p < 0.001). CONCLUSIONS: Elevated serum tyrosine concentration, but not changes in serum BCAA concentration or the BCAA-to-tyrosine ratio, may indicate a high risk of death or liver transplantation for patients with liver cirrhosis.

RESUMEN

AIM: Chronic liver insufficiency is often associated with alteration in amino acid metabolism. We evaluated the prognostic value of changes in serum amino acid concentrations in patients with primary biliary cholangitis. METHODS: A total of 75 primary biliary cholangitis patients who started urusodeoxycholic acid therapy were retrospectively enrolled. Baseline serum concentrations of branched-chain amino acids and tyrosine, and branched-chain amino acid-to-tyrosine ratio were determined. The hazard ratios of factors associated with liver-related events were analyzed by Cox proportional hazard analysis. RESULTS: Of the 75 patients enrolled, 12 showed a decrease in serum branched-chain amino acid levels, and 15 showed an increase in serum tyrosine levels. The branched-chain amino acid-to-tyrosine ratio decreased in 16 patients. During a median 5.6-year follow up, liver-related events occurred in 11 patients. Multivariate analysis showed that high serum tyrosine levels at baseline and high alkaline phosphatase levels 48 weeks after starting urusodeoxycholic acid therapy were independent risk factors for event occurrence. From the receiver operator characteristics curve analysis, serum tyrosine concentration >110 µmol/L was identified as a cut-off value with an adjusted hazard ratio of 20.9 (95% confidence interval 4.3-101.5, P < 0.001). Kaplan-Meier analysis showed that the 5-year cumulative incidences of event occurrence in patients with high and low serum tyrosine concentration were 56.5% and 5.5%, respectively (P < 0.001). The 10-year survival probabilities also showed significant differences between patients with high and low serum tyrosine concentration (44.9% vs. 92.0%, P < 0.001). CONCLUSION: Elevation of serum tyrosine concentration indicates a high risk of liver-related events in primary biliary cholangitis patients receiving urusodeoxycholic acid therapy.

RESUMEN

We aimed to analyze the serum level of a novel fibrosis marker, Mac-2-binding protein glycosylation isomer (M2BPGi), and its predictive value for hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) under nucleot(s)ide analogue (NA) therapy. Serum M2BPGi levels were quantified in 147 CHB patients at baseline, 48 weeks after starting NA therapy, and at the patients' last visit. The serum M2BPGi level serially decreased at each time point. During the median follow-up time of 6.6 years, 14 of 147 patients developed HCC. Multivariate Cox proportional hazard analysis demonstrated that high serum M2BPGi at 48 weeks was an independent risk factor for HCC development. A cutoff value of M2BPGi at 48 weeks > 1.5 showed an adjusted hazard ratio = 34.9 (95% confidence interval, 4.3-284.9). The 3- and 5-year cumulative incidence of HCC in patients with low M2BPGi were 0.9% and 4.2%, respectively, whereas those in patients with high M2BPGi were 10.1% and 25.6%, respectively (p < 0.001). In conclusion, Serum M2BPGi level at 48 weeks is a useful predictor for HCC development in patients with CHB who receive NA therapy.

RESUMEN

AIM: Recent reports have indicated that aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was upregulated in some chronic liver diseases. However, few studies have reported AKR1B10 expression in chronic hepatitis B virus (HBV)-infected patients. The aim of the present study was to analyze AKR1B10 expression and its relevance on hepatocellular carcinoma (HCC) development in patients with chronic HBV infection. METHODS: Expression of AKR1B10 in the liver of 119 chronic HBV-infected patients was assessed and quantified immunohistochemically. A multivariate Cox model was used to estimate the hazard ratios of AKR1B10 expression for HCC development. The cumulative incidences of HCC were evaluated using Kaplan-Meier analysis. RESULTS: Expression of AKR1B10 in the study cohort ranged from 0% to 84%. During the median follow-up time (6.2 years), 13 patients developed HCC. Multivariate analysis revealed that high AKR1B10 expression (≥15%) was an independent risk factor for HCC (hazard ratio, 10.8; 95% confidence interval, 3.0-38.6; P < 0.001). The 5-year cumulative incidences of HCC were 20.6% and 2.6% in patients with high and low AKR1B10 expression, respectively (P < 0.001). Patients with high AKR1B10 expression had significantly higher alanine aminotransferase levels during follow-up than those with low expression, even though antiviral treatment decreased HBV-DNA levels in both groups. CONCLUSION: Chronic HBV-infected patients with high hepatic AKR1B10 expression had an increased risk of HCC development. This suggests that AKR1B10 upregulation might play a role in the early stages of HBV-related hepatocarcinogenesis.

RESUMEN

BACKGROUND AND AIM: Aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was recently reported to be upregulated in some chronic liver diseases. However, its relevance in hepatocellular carcinoma (HCC) development is not fully assessed, especially in patients with chronic hepatitis C virus (HCV) infection. METHODS: Aldo-keto reductase family 1 member B10 expression in the liver of 550 patients with chronic HCV infection was immunohistochemically assessed and quantified. A multivariate Cox model was used to estimate the hazard ratios (HRs) of AKR1B10 expression for HCC development, and the cumulative incidence of HCC was evaluated using the Kaplan-Meier method. RESULTS: Aldo-keto reductase family 1 member B10 expression in the patients ranged from 0% to 80%. During the median follow-up of 3.2 years, 43 of 550 patients developed HCC. Multivariate analysis demonstrated that high AKR1B10 expression (≥6%) was an independent risk factor for HCC (HR, 6.43; 95% confidence interval, 2.90-14.25; P < 0.001). The 5-year cumulative incidences of HCC were 22.8% and 2.2% in patients with high and low AKR1B10 expression, respectively (P < 0.001). In subgroup analyses, the effects of high AKR1B10 expression on HCC development risk were significant over strata. In particular, HRs attributed to high AKR1B10 expression were significant in the subgroups that had been considered at a lower risk of HCC, such as in patients with younger age and mild hepatic fibrosis or those who achieved sustained virological response after interferon therapy. CONCLUSION: Various degrees of AKR1B10 upregulation in the liver were observed in patients with chronic HCV infection, and high AKR1B10 expression could be a novel predictor of HCC.

RESUMEN

We aimed to clarify the association between a novel serum fibrosis marker, Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA⁺-M2BP), and hepatocellular carcinoma (HCC) development in 355 patients with chronic hepatitis C who achieved sustained virologic response (SVR) through interferon-based antiviral therapy. Pretreatment serum WFA⁺-M2BP levels were quantified and the hazard ratios (HRs) for HCC development were retrospectively analyzed by Cox proportional hazard analysis. During the median follow-up time of 2.9 years, 12 patients developed HCC. Multivariate analysis demonstrated that high serum WFA⁺-M2BP (≥2.80 cut off index (COI), HR = 15.20, p = 0.013) and high fibrosis-4 (FIB-4) index (≥3.7, HR = 5.62, p = 0.034) were independent risk factors for HCC development. The three- and five-year cumulative incidence of HCC in patients with low WFA⁺-M2BP were 0.4% and 0.4%, respectively, whereas those of patients with high WFA⁺-M2BP were 7.7% and 17.6%, respectively (p < 0.001). In addition, combination of serum WFA⁺-M2BP and FIB-4 indices successfully stratified the risk of HCC: the five-year cumulative incidences of HCC were 26.9%, 6.8%, and 0.0% in patients with both, either, and none of these risk factors, respectively (p < 0.001). In conclusion, pretreatment serum WFA⁺-M2BP level is a useful predictor for HCC development after achieving SVR.

RESUMEN

BACKGROUND AND AIM: The purpose of this study was to evaluate the usefulness of liver stiffness measurement (LSM) for assessing the risk of hepatocellular carcinoma (HCC) in chronic hepatitis C (CHC) patients receiving interferon (IFN) therapy. METHODS: One hundred fifty-one CHC patients who underwent LSM and received IFN therapy were included in the estimation cohort, and 56 were included in the validation study. The cumulative HCC incidences were evaluated using Kaplan-Meier plot analysis and the log-rank test. Multivariate Cox proportional hazard analyses were used to estimate the hazard ratios (HRs) of variables for HCC. RESULTS: In the estimation cohort, 9 of 151 patients developed HCC during the median follow-up time of 722 days. Multivariate analysis identified three independent risk factors for HCC: LSM (≥ 14.0 kPa, HR 5.58, P = 0.020), platelet count (< 14.1 × 10(4) /µL, HR 5.59, P = 0.034), and non-sustained virological response (HR 8.28, P = 0.049). The cumulative incidence of HCC development at 3 years was 59.6%, 8.2%, and 0.0% in patients with all three risk factors, one to two risk factors, and none of these risk factors, respectively. The incidence of HCC was significantly different between these groups (P < 0.001). In the validation cohort, HCC incidence was also significantly different with respect to these risk factors (P = 0.037). CONCLUSION: LSM, platelet count, and IFN-therapeutic effect could be used to successfully stratify the risk of HCC in patients receiving IFN therapy and demonstrate the usefulness of LSM before IFN therapy for the management of CHC patients.

RESUMEN

Aldo-keto reductase family 1, member B10 (AKR1B10), a cancer-related oxidoreductase, is expressed in well-differentiated hepatocellular carcinomas (HCCs). However, AKR1B10 levels are minimal in normal liver tissues (NLs), similar to the 70-kilodalton heat shock protein (HSP70) and glypican-3. Moreover, the role of AKR1B10 in chronic hepatitis or cirrhosis, which are considered preneoplastic conditions for HCC, has not been fully elucidated. The aim of this study was to evaluate the expression of AKR1B10, HSP70, and glypican-3 in 61 HCC tissue samples compared to corresponding non-tumorous liver tissues (NTs), comprising 42 chronic hepatitis and 19 cirrhosis cases to clarify the significance of molecular changes at the preneoplastic stages of HCC. Immunohistochemical analysis demonstrated that the median expression levels of AKR1B10 were higher in HCCs than in NTs (p<0.001) and higher in NTs than NLs (p<0.001) with 54.8%, 2.1%, and 0.3% expression in HCCs, NTs, and NLs, respectively. HSP70 and glypican-3 were expressed in HCCs, but minimally in NTs and NLs with no significant difference between expression in NTs and NLs. Furthermore, a multivariate analysis identified an association between hepatic steatosis and AKR1B10 expression in NTs (p=0.020). Of the three protein expressed in well-differentiated HCCs, only AKR1B10 was upregulated in preneoplastic conditions, and a steatosis-related factor might influence its expression.

RESUMEN

BACKGROUND: Elevated serum alpha-fetoprotein (AFP) is not only a diagnostic marker for hepatocellular carcinoma (HCC), but is also a risk factor for HCC in chronic hepatitis C patients who do not have HCC. AIM: The aim was to analyse the hepatic gene expression signature in chronic hepatitis C patients with elevated AFP, who were at high risk for HCC. METHODS: Liver tissue samples from 48 chronic hepatitis C patients were stratified by their serum AFP levels and analysed for gene expression profiles. The association between aldo-keto reductase family 1 member B10 (AKR1B10) expression and serum AFP was confirmed by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemical analyses. A matched case-control study was performed to evaluate the risk of AKR1B10 expression for HCC development. RESULTS: Distinct hepatic gene expression patterns were demonstrated in patients with elevated AFP (≥10 ng/mL) and normal AFP (<10 ng/mL). Of the 627 differently expressed genes, the most abundantly expressed gene in patients with elevated AFP was AKR1B10 (fold change, 26.2; P < 0.001), which was originally isolated as an overexpressed gene in human HCC. The qRT-PCR and immunohistochemical studies confirmed a proportional correlation between AKR1B10 expression and serum AFP. A matched case-control study identified that AKR1B10 up-regulation (>6%) was an independent risk factor for HCC development (hazard ratio, 21.4; P = 0.001). CONCLUSION: AKR1B10 was up-regulated in association with serum AFP, and was an independent risk factor for HCC in chronic hepatitis C patients, suggesting its possible involvement at a very early stage of hepatocarcinogenesis.

RESUMEN

Direct-acting antiviral (DAA) therapy carries a potential risk of inducing hepatitis B virus (HBV) reactivation. However, the HBV kinetics during and after DAA therapy in patients co-infected with hepatitis C virus (HCV) and HBV remain unknown. We retrospectively evaluated the HBV kinetics during and after sofosbuvir/ribavirin therapy in four HBV inactive carriers co-infected with HCV. HCV was eradicated in all patients. Changes in HBV-DNA levels during treatment differed among patients. The hepatitis B surface antigen (HBsAg) levels uniformly decreased (mean -0.530 logIU/mL) by the end of treatment and returned to near the baseline in all patients. Sofosbuvir/ribavirin therapy thus demonstrated a suppressive effect on HBsAg.

RESUMEN

AIMS: Recent advances of direct-acting antiviral drugs for hepatitis C virus (HCV) have dramatically improved the sustained virologic response (SVR) rate, but hepatocellular carcinoma (HCC) development rarely occurs even in patients who achieve an SVR. Wisteria floribunda agglutinin-positive mac-2-binding protein (WFA+-M2BP) was recently developed as a noninvasive biomarker of liver fibrosis. However, the association between the WFA+-M2BP level and HCC development after the achievement of an SVR is unclear. METHODS AND RESULTS: We examined the association between WFA+-M2BP and HCC development in 522 HCV patients who achieved an SVR (Interferon [IFN]-based therapy, n = 228; IFN-free therapy, n = 294). Multivariate analysis revealed that a high WFA+-M2BP level at SVR week 24 after treatment (SVR24) (hazard ratio [HR] = 1.215, P = 0.020), low platelet counts (HR = 0.876, P = 0.037), and old age (HR = 1.073, P = 0.012) were independent risk factors for HCC development regardless of the treatment regimen. Receiver operator characteristics curve analysis revealed that a WFA+-M2BP level at SVR24 of ≥1.62 cut-off index (COI) was the cut-off value for the prediction of HCC development (adjusted HR = 12.565, 95% CI 3.501-45.092, P < 0.001). The 3- and 5-year cumulative incidences of HCC were 1% and 1.6% in patients with low WFA+-M2BP at SVR24 (<1.62 COI), and 4.7% and 12.5% in patients with high WFA+-M2BP (≥1.62 COI) were, respectively (P < 0.001). CONCLUSIONS: The assessment of liver fibrosis using the WFA+-M2BP level at SVR24 is a useful predictor of HCC development after HCV eradication even in the IFN-free therapy era.

RESUMEN

METHODS: Two hundred and forty seven of 480 patients with naïve papilla undergoing therapeutic ERCP between April 2013 and March 2018 were enrolled for the study. The following patient characteristics were investigated: age, sex, body mass index, previous diseases (heart disease, renal failure, cerebrovascular disorders, coexisting malignancy and pulmonary disease), history of PEP, common bile duct diameter, diverticula and volume of fluid infused 24 hours after the procedure. All ERCP cases had naïve papilla and had undergone treatment. RESULTS: The incidence of PEP was 8.5%. Significant differences were observed in the volume of fluid infused between patients without and with a history of heart disease (1,380 vs. 1,755 mL). The mean volume of the infused fluid was significantly lower in the PEP than non-PEP group (1,483 vs. 1,688 mL, P = 0.02). Moreover, PEP incidence differed according to a fluid infusion cutoff of 1,000 mL (7 vs. 11 cases of PEP in those with ≦1,000 mL and >1,000 mL fluid volume, respectively, P < 0.001). CONCLUSION: Restricted fluid volume was a newly identified risk factor for PEP, particularly in patients with heart and renal diseases as comorbidities.

RESUMEN

A 42-year-old woman was admitted to our hospital with cholestatic liver injury. Serological examination revealed anti-mitochondrial M2 antibody positivity and anti-nuclear antibody and anti-smooth muscle antibody negativity. Histological examination of the first liver biopsy revealed chronic nonsuppurative destructive cholangitis with epithelioid granulomas. Ursodeoxycholic acid therapy successfully treated her cholestasis. Sixteen months later, she developed acute icteric hepatitis with elevation of serum aspartate and alanine aminotransferase levels. Anti-mitochondrial M2 positivity and anti-nuclear antibody and anti-smooth muscle antibody negativity persisted at that time. However, it became clear that anti-liver kidney microsomal type 1 antibody was positive. Histological examination of the second liver biopsy demonstrated scarce interface hepatitis and evident parenchymal inflammation and centrilobular zonal necrosis. Her liver biochemical test results promptly improved with the addition of prednisolone therapy. Considering the findings, she was diagnosed with primary biliary cholangitis-type 2 autoimmune hepatitis overlap syndrome. According to a literature review, this is an extremely rare autoimmune overlap syndrome.

RESUMEN

OBJECTIVES: Bacterial infection is a major complication in patients with liver cirrhosis. Procalcitonin is an early diagnostic marker of bacterial infection. This study aimed to investigate the association between the serum procalcitonin levels and the prognosis of patients with liver cirrhosis. METHODS: We retrospectively analyzed the serum procalcitonin levels in 236 hospitalized patients with liver cirrhosis. The impact of the serum procalcitonin level on their prognoses was evaluated using multivariate Cox proportional hazards analyses and the Kaplan-Meier method. RESULTS: The serum procalcitonin level was higher (≥0.05 ng/mL) in 151 (64%) patients, and it was significantly higher in the patients with Child-Turcotte-Pugh class C than in those with Child-Turcotte-Pugh classes A/B. Patients with refractory ascites, hepatic encephalopathy, gastrointestinal bleeding, and bacterial infections had elevated serum procalcitonin levels. The multivariate analyses showed a serum procalcitonin level ≥0.05 ng/mL was an independent prognostic factor for liver cirrhosis (hazard ratio = 1.64; 95% confidence interval = 1.07-2.53; P = 0.024). During a median follow-up interval of 2.1 years, the three-year cumulative survival rates for the patients with normal and elevated serum procalcitonin levels were 72.9 and 56.0%, respectively (P < 0.001). The subgroup analyses that stratified the patients according to age, the Child-Turcotte-Pugh classification, and the presence of liver cancer showed the serum procalcitonin level was significantly associated with their prognoses. CONCLUSIONS: The patients with liver cirrhosis had higher serum procalcitonin levels, regardless of local bacterial infections, and higher procalcitonin levels were associated with poor prognoses.

RESUMEN

Follow-up computed tomography revealed a 40-mm pancreatic tail cyst in a 59-year-old man with type 1 diabetes mellitus. An intraductal papillary mucinous neoplasm was suspected; mucinous cystic neoplasm (MCN) was not considered because the patient was a man. During follow-up, cyst infection occurred but was improved by conservative treatment. At the 24-month follow up examination, cyst nodules had developed, corresponding to an increase in the carbohydrate antigen 19-9 level. Mucinous cystadenocarcinoma (MCC) was diagnosed pathologically based on distal pancreatectomy. A diagnosis of male MCN/MCC is often delayed, which may lead to a poor prognosis. MCN infection is also rare and poorly recognized. We observed an atypical male case of MCN/MCC.

RESUMEN

Management of hemosuccus pancreaticus (HP) due to pancreatic adenocarcinoma is problematic. This is the first report of the successful management of HP caused by pancreatic adenocarcinoma by chemoradiotherapy, which is a treatment option for cases with a high surgical risk that are not suitable for interventional radiology. In the present case, bloody pancreatic juice was detected in the main pancreatic duct, and anemia worsened without repeated blood transfusions. The patient ultimately underwent chemoradiotherapy comprising radiation of 3 Gy in 15 fractions concomitant with systemic chemotherapy of S-1. After the treatments, the anemia improved, and the patient was discharged on day 45.

RESUMEN

A 45-year-old man with steroid-dependent ulcerative pancolitis was hospitalized with frequent diarrhea, abdominal pain and distension 3 months after induction of golimumab, a tumor necrosis factor-alpha antagonist. Computed tomography showed wall thickening from the stomach to the colon and massive ascites. Peripheral blood test revealed eosinophilia. A large number of eosinophils were observed in the ascites fluid. Although esophagogastroduodenoscopy showed no abnormal findings and colonoscopy showed ulcerative colitis with a Mayo endoscopic subscore of 1, eosinophil infiltration was histologically observed. Based on these findings, we diagnosed him with eosinophilic gastroenteritis and started prednisolone. Consequently, his eosinophil counts and abdominal symptoms dramatically improved.

RESUMEN

A 69-year-old man was under maintenance dialysis due to diabetic renal failure. He had a drop in blood pressure during dialysis, developed hematemesis, and was transported to our hospital. Emergency upper gastrointestinal endoscopy revealed diffuse erosion, mucosal sloughing, and edematous mucosa in the upper body of the stomach to the posterior wall of the antrum and to the greater curvature, which were considered to be an ischemic change. His underlying diseases included diabetic renal failure, chronic arteriosclerosis obliterans, cerebral infarction, internal carotid artery stenosis, hypertension, and myocardial infarction. Blood evaluation showed only mild inflammation and no fibrinolytic hyperactivity. Contrast-enhanced computed tomography (CECT) showed no occlusion of blood vessels. It was considered that the patient had a transient ischemic change due to blood pressure drop. The patient's condition improved with conservative treatment.

RESUMEN

AIM: To clarify the association between aldo-keto reductase family 1 member B10 (AKR1B10) expression and hepatocarcinogenesis after hepatitis C virus eradication. METHODS: In this study, we enrolled 303 chronic hepatitis C patients who had achieved sustained virological response (SVR) through interferon-based antiviral therapy. Pretreatment AKR1B10 expression in the liver was immunohistochemically assessed and quantified as a percentage of positive staining area by using image-analysis software. A multivariate Cox analysis was used to estimate the hazard ratios (HRs) of AKR1B10 expression for hepatocellular carcinoma (HCC) development after achieving SVR. The cumulative incidences of HCC development were evaluated using Kaplan-Meier analysis and the log-rank test. RESULTS: Of the 303 chronic hepatitis C patients, 153 (50.5%) showed scarce hepatic AKR1B10 expression, quantified as 0%, which was similar to the expression in control normal liver tissues. However, the remaining 150 patients (49.5%) exhibited various degrees of AKR1B10 expression in the liver, with a maximal AKR1B10 expression of 73%. During the median follow-up time of 3.6 years (range 1.0-10.0 years), 8/303 patients developed HCC. Multivariate analysis revealed that only high AKR1B10 expression (≥ 8%) was an independent risk factor for HCC development (HR = 15.4, 95%CI: 1.8-132.5, P = 0.012). The 5-year cumulative incidences of HCC development were 13.7% and 0.5% in patients with high and low AKR1B10 expression, respectively (P < 0.001). During the follow-up period after viral eradication, patients expressing high levels of AKR1B10 expressed markedly higher levels of alanine aminotransferase and α-fetoprotein than did patients exhibiting low AKR1B10 expression. CONCLUSION: Chronic hepatitis C patients expressing high levels of hepatic AKR1B10 had an increased risk of HCC development even after SVR.

RESUMEN

PURPOSE: The serum hepatitis C virus (HCV) load is persistently stable in patients with untreated chronic hepatitis C, but its differences between individuals vary widely (above 4 logU/mL). Because serum viral load is an important factor for predicting clinical outcome of interferon-based antiviral therapy, this study was performed to clarify the factors associated with serum viral load in chronic hepatitis C patients. METHODS: We retrospectively analyzed data from 669 chronic hepatitis C patients with HCV genotype 1 or 2 infection. Stepwise regression analysis was used to estimate the relationship between demographic, viral, or biochemical variables and serum viral load. RESULTS: In univariate analysis, serum lipid profiles, such as total cholesterol, low-density lipoprotein (LDL) and triglyceride levels, and hemoglobin A1c (HbA1c) were correlated with the serum HCV viral load. In multivariate analysis, HCV genotype 1 infection and higher total cholesterol levels were associated with higher viral load. After stratification by HCV genotype, the serum viral load was associated with triglyceride and HbA1c in genotype 1 and with platelet counts and LDL in genotype 2. Histological data (413 patients) showed correlation between severe liver fibrosis and decreased serum viral load in patients with HCV genotype 2 but not genotype 1 infection. CONCLUSIONS: These results suggest that viral kinetics is affected by different host factors for genotypes 1 and 2.
