Abstract
BACKGROUND

Hepatitis B virus (HBV) is a hepatotropic virus that can cause acute and chronic liver damage. According to the world health organization 257 million people are infected with chronic HBV infection worldwide. Super-infection with other hepadnaviruses, including hepatitis A virus (HAV), hepatitis C virus, hepatitis D virus, and hepatitis E virus is associated with increased risk of acute liver failure in patients with chronic HBV.

CASE SUMMARY

Here, we report a case of a 47-year old male patient with HBV-related compensated Child A cirrhosis, who presented with general fatigue, malaise and laboratory signs of acute hepatitis. Although the patient was regularly seen at a specialized university liver unit, the HAV vaccination status was unclear. Acute HAV super-infection was diagnosed by positive serological and polymerase chain reaction analysis. Following acute HAV super-infection, spontaneous HBsAg elimination and development of an anti-HBs titer were observed.

CONCLUSION

This case illustrates the importance of carefully checking the vaccination status. In our patient, unspecific immunological responses to HAV led to functional cure of HBV.

Core tip: In patients with chronic hepatitis B virus (HBV) infection, super-infection with other hepatotropic viruses can lead severe liver diseases with acute on chronic liver failure, underlying the need to check for a complete hepatitis A virus (HAV) vaccination status. Here, we present an unvaccinated patient with HBV related liver cirrhosis who experienced an acute HAV super-infection. HAV infection was spontaneously cleared without signs of acute liver failure. Furthermore, most likely to an unspecific immunological response functional cure of HBV was observed (seroconversion of HBsAg to anti-HBs).
