Background: The risk of mother to child transmission of hepatitis B virus (HBV) is recognized worldwide, a reason for which the World Health Organization aims to reduce this public health issue of major concern in the next ten years. The aim of our study was to detect circulating HBV genotypes in a selected population of pregnant women, as scientific evidence to recommend personalized antiviral therapy and to obtain updated epidemiological information.
Methods: HBsAg positive pregnant women were selected by the National Institute of Public Health Romania. Blood samples were collected after signing the informed consent. The HBV genotypes were tested by INNO LiPA HBV genotyping method.
Results. The D genotype was detected in 9/18 (50%) patients, genotype A in 3/18 (16.7%), and genotype F in 3/18 (16.7%) patients. Three patients had double infection, 11 had unique infection, and 4 had no detectable genotype.
Conclusion. This study confirmed the results of previous studies regarding HBV genotype circulation in our country, with the mention that F genotype was a new one for our area. These data are useful from an epidemiological point of view and also for therapeutical reasons, as it is known that therapy should be genotype guided.
