Resumo: 	Abstract  Background: Chronic hepatitis B is a major cause of cirrhosis, and the natural history of the disease has several clinical stages that should be thoroughly understood for the implementation of proper treatment. Nonetheless, curing the disease with antiviral treatment remains a challenge.  Aims: To describe the clinical course, response to treatment, and poor prognostic factors in 247 hepatitis B virus chronic infection patients treated in a tertiary hospital in Brazil.  Methods: This was a retrospective and observational study, by analyzing the medical records of HBV infected patients between January 2000 and January 2015.  Results: Most patients were male (67.2%) and 74.1% were HBeAg negative. Approximately 41% had cirrhosis and 8.5% were hepatitis C virus coinfected. The viral load was negative after two years on lamivudine, entecavir and tenofovir in 86%, 90.6%, and 92.9% of the patients, respectively. The five-year resistance rates for lamivudine, adefovir, entecavir, and tenofovir were 57.5%, 51.8%, 1.9%, and 0%, respectively. The overall seroconversion rates were 31.2% for HBeAg and 9.4% for HBsAg. Hepatocellular carcinoma was diagnosed in 9.7% of patients, liver transplantation was performed in 9.7%, and overall mortality was 10.5%. Elevations of serum alanine aminotransferase (p = 0.0059) and viral load (p &lt; 0.0001) were associated with progression to liver cirrhosis. High viral load was associated with progression to hepatocellular carcinoma (p &lt; 0.0001). Significant risk factors associated with death were elevated alanine aminotransferase (p = 0.0039), liver cirrhosis (p &lt; 0.0001), high viral load (p = 0.007), and hepatocellular carcinoma (p = 0.0008). HBeAg positive status was not associated with worse outcomes, and treatment may have been largely responsible.  Conclusions: Elevations of viral load and serum alanine aminotransferase may select patients with worse prognosis, especially progression to cirrhosis and hepatocellular carcinoma, which were strongly association with death.
