Long-term follow-up of patients with hepatitis C with a normal alanine aminotransferase

Risk factors for hepatocellular carcinoma in Caucasian patients with non-viral cirrhosis: the importance of prior obesity

BACKGROUND & AIMS

In patients with cirrhosis, the risk of hepatocellular carcinoma (HCC) depends upon age, gender and the etiology of liver disease. Few studies are available in Caucasian patients with alcoholic or metabolic cirrhosis without viral hepatitis.

METHODS

Cross-sectional clinical data from 905 HCV- and HBV-negative Caucasian patients with alcoholic or metabolic cirrhosis were prospectively collected in four French centres. The risk factors for HCC were identified by logistic regression analysis in the whole population and in a nested case-control study.

RESULTS

The etiology of cirrhosis was alcoholic (48%), metabolic (7%) or mixed (45%). Patients were predominantly male (80%), mean age 62 years old and 31% had HCC. Mean body mass index (BMI) was 27 ± 5 and 30% were obese at inclusion. The maximum BMI reached throughout life was 31 ± 6 and 63% had been obese. Ninety percent of the population had daily alcohol consumption, 73% were smokers. Hepatocellular carcinoma was independently related to male gender (P < 0.0001), older age (P < 0.0001), past obesity (P = 0.007), diabetes (P = 0.037), abnormal levels of transaminases (P < 0.0001) and tobacco consumption (P = 0.007). The case-control study (200 HCC cases matched with 400 non-HCC cases for gender, age and Child-Pugh score) confirmed past obesity, tobacco and abnormal levels of transaminases.

CONCLUSIONS

Beside diabetes, male gender and age, a past history of obesity, but not an existing overweight, as well as exposure to tobacco and elevated transaminases were three risk factors which could improve the strategy for HCC screening in Caucasian cirrhotic patients without hepatitis B or C.

Prediction of a favorable clinical course in hepatitis C virus carriers with persistently normal serum alanine aminotransferase levels: A long-term follow-up study

AIM

This study examined serum alanine aminotransferase (ALT) levels at first visit and their relationship with long-term normal serum ALT levels in hepatitis C virus (HCV) carriers with persistently normal ALT (PNALT).

METHODS

HCV carriers with PNALT were identified as those patients with positivity of serum HCV RNA, ALT levels of 30 IU/L or less over a 12-month period on at least three different occasions, platelet count of more than 15 × 10(4)  μl/mL and body mass index of 30 kg/m(2) or less. Outcome was retrospectively studied in 49 HCV carriers with PNALT, who were followed up for more than 10 years.

RESULTS

During the mean follow-up period of 14.7 ± 2.5 years, ALT levels of 30 IU/L or less were preserved in only eight patients (8/49; 16.3%). Among the 17 patients with initial ALT levels of 19 IU/L or less, nine patients remained with ALT levels of 30 IU/L or less after 10 years (9/17; 52.9%). The probability of ALT levels in PNALT being maintained at 30 IU/L or less was significantly higher (P = 0.001) in these patients than in those with initial ALT levels of 20 IU/L or more (n = 32). Abnormal ALT levels were more common in female PNALT patients aged 45-55 years, which is usually the time of menopause onset.

CONCLUSION

Because antiviral therapy in the treatment of chronic hepatitis C is rapidly advancing, waiting for more effective and safer treatments may be an option. The results of this study provide an important insight into this issue.

Management of hepatitis C; Report of the Consensus Meeting at the 45th Annual Meeting of the Japan Society of Hepatology (2009)

The consensus meeting for the diagnosis, management and treatment for hepatitis C was held in 45(th) annual meeting for the Japan Society of Hepatology (JSH) in June 2009 where the recommendations and informative statements were discussed including organizers and presenters. The Several important informative statements and recommendations have been shown. This was the fourth JSH consensus meeting of hepatitis C, however, the recommendations have not been published in English previously. Thus, this is the first report of JSH consensus of hepatitis C. The rate of development of hepatocellular carcinoma (HCC) in HCV-infected patients in Japan is higher than in the USA, because the average age of the HCV-infected patients is greater and there are more patients with severe fibrosis of the liver than in the USA. In Japan, more than 60% of HCV-infected patients are genotype 1b infection, and they show lower response to perinterferon and ribavirin combination treatment. To improve the response rate is also an important issue in our country. To establish the original recommendations and informative statements to prevent the development of HCC is a very important issue in Japan.

Use of epoetin beta during combination therapy of infection with hepatitis c virus with ribavirin improves a sustained viral response

The aim of the study was to evaluate the effects of epoetin-beta on anemia and sustained viral response in patients with chronic hepatitis C receiving treatment with pegylated interferon and ribavirin. Forty-two Caucasian patients with chronic hepatitis C infection, treated with pegylated interferon alpha-2a or alpha-2b plus ribavirin, who experienced at least a 2 log decline in HCV-RNA in the first month of therapy and a > or =2.5 g/dl hemoglobin drop from baseline, were recruited. They were divided into two groups: 22 patients received epoetin-beta 30,000 U administered s.c. q.w. (group A) and 20 patients received a reduced ribavirin dose of 600 mg daily (group B). The end-of-treatment response was 95.4% (21/22) in group A and 80% (16/20) (P = 0.2) in group B. Sustained viral response in group A was 81.8% (18/22), statistically higher than in group B (45%, 9/20) (P = 0.03). Mean corpuscular volume of erythrocytes was statistically lower in group A than in group B 4 weeks after starting epoetin-beta or reduced ribavirin dose (P < 0.001), end-of-treatment (P < 0.001) and after 6 months follow-up (P < 0.001). A negative correlation between the levels of ferritin serum was found in group A at the baseline and mean corpuscular volume value after 1 month of combination antiviral therapy (r = -0.45; P = 0.35), 4 weeks after starting epoetin-beta (r = -0.43; P = 0.04) and after 6 months follow-up (r = -0.45; P = 0.03). Administration of epoetin-beta increases sustained viral response rates among patients developing anemia, because the standard dose of ribavirin is maintained, thereby reducing the side-effects of antiviral treatment.

High serum alanine aminotransferase levels for the first three successive years can predict very high incidence of hepatocellular carcinoma in patients with Child Stage A HCV-associated liver cirrhosis

Abstract Objective. To assess retrospectively whether continuously high serum alanine aminotransferase (ALAT) levels (<80 IU) in the first three successive years after the diagnosis of liver cirrhosis (LC) are predictive of a subsequent high incidence of hepatocellular carcinoma (HCC) in patients with Child Stage A hepatitis C virus (HCV)-LC. Material and methods. The study comprised 132 HCV-LC (Child Stage A) patients who had not received interferon therapy but had been treated with anti-inflammatory agents. At the end of a 3-year follow-up after the diagnosis of LC, the patients were subdivided into three groups according to their serum ALAT levels and the subsequent incidence of HCC was assessed. Results. The cumulative incidence of HCC starting from 3 years after the diagnosis of LC in the continuously high ALAT group (annual average over 3 years always > or =80 IU; n=41; Group A) was markedly higher than that in the continuously low ALAT group (always <80 IU; n=48; Group B) (p<0.005) during an observation period of 7.9+/-3.7 years. The incidence of HCC in Group A was 11.8%/year. The odds ratios of developing HCC in Group A and Group C (mixed high and low ALAT levels; n=43) were 5.1-fold and 1.5-fold that of Group B, respectively. A multivariate analysis revealed that the ALAT group was independently associated with HCC development. Conclusions. Continuously high ALAT levels for three successive years following the diagnosis of LC can be predictive of a very high incidence of HCC in Child A HCV-LC patients. Prospective trials using therapeutic approaches aimed at decreasing ALAT levels are necessary in order to confirm a positive impact of ALAT reduction on the incidence of HCC in patients with HCV-LC.
