Introduction
Laboratory
* criteria for treatment (see Management: below)
Diagnostic procedures
- screen for heptocellular carcinoma in at risk patients with ultrasound every six months[1]*
* screening with serum alpha-fetoprotein insufficient[1]
Complications
- chronic active hepatitis
- cirrhosis
- risk factors
- older age
- longer duration of infection
- high hepatitis B virus DNA
- long-term alcohol use
- HIV or hepatitis C virus coinfection
- smoking
- risk factors
- hepatocellular carcinoma
- cirrhosis
- HBV genotype C
- conversion from HBeAg(-) to HBeAg(+)
- male
- family history of hepatocellular carcinoma
- may develop in the absence of cirrhosis[1]
- lipophilic statins (atorvastatin, simvastatin) may reduce (risk 3% vs 8%)[4]
Management
- patients in the immune control (inactive) phase generally do not require treatment[1]
treatment indicated for HBeAg(-) patients with
- serum ALT > 2-fold upper limit of normal &
- hepatitis B virus DNA > 2000 IU/mL
- entecavir or tenofovir 1st line for treatment[3]
- lamivudine & adefovir no longer 1st line due to lower potency & development of resistance
- pegylated interferon (avoid in patients with depression)
- most patients will require therapy indefinitely
- cure rates are low[3]
- bepirovirsen is an antisense oligonucleotide that targets all hepatitis B virus messenger RNAs & decreases levels of hepatitis B viral proteins (investigational)[5]
