Introduction. Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are two major causes of death worldwide. These two viruses share routes of transmission, and therefore, HIV–HBV coinfection is common and is associated with low plasma levels of CD4 T lymphocytes and accelerated liver disease progression. Maternal HIV and HBV infections have been individually associated with preterm birth and low birth weight. Case presentation. We describe the case of a 28-year-old patient, 14 weeks pregnant, asymptomatic, who performed Elisa-HIV 1,2 test within prenatal screening, with a positive result, in 2018. From the medical history, we mention that the patient is known for about 5 years with HBV-hepatitis D virus coinfection, for which she underwent interferon treatment for a year. ART was initiated after one month with lamivudine / zidovudine + lopinavir / ritonavir. The patient was adherent to ART (adherence ≥ 95%) during pregnancy. Before birth, the immunovirological evaluation revealed the suppression of maternal HIV viral load, a moderate degree of immunosuppression and undetectable HBV-DNA. The patient gave birth by caesarean section to a female child, with a gestational age of 36 weeks, birth weight of 1730 g, lenght = 43 cm, head circumference = 30 cm, APGAR score = 8 points. The child received antiretroviral prophylaxis with retrovir+epivir, human hepatitis B immunoglobulin and was vaccinated against hepatitis B. The newborn was not vertically infected with HIV and HBV. Conclusions. Good adherence to ART during pregnancy has been associated with HIV viral load and HBV-DNA suppression and it led to the birth of a child who has not been infected with HIV or HBV. Maternal HIV-HBV coinfection was a significant risk factor for preterm birth and low birth weight.
