Mutations occurring in viral polymerase gene of hepatitis B virus (HBV) due to the use of nucleos(t)id analogs reduce the activity of the drugs by causing antiviral resistance. In this study, it was aimed to evaluate mutations responsible for drug resistance and drug resistance mutation rates in patients followed up by the diagnosis of chronic hepatitis B (CHB). A total of 318 CHB patients were included in the study.

- Human herpesvirus 8 (HHV-8) is linked to diseases like Kaposi's sarcoma and has low prevalence in the general population but is higher in individuals with immunodeficiencies, particularly AIDS.
- A study aimed to determine HHV-8 seroprevalence in healthy blood donors and HIV-positive patients in Turkey, including a sample of 551 healthy donors and 173 HIV-positive individuals.
- Results showed a significant difference in HHV-8 seropositivity: 5.3% in blood donors versus 25.4% in HIV-positive patients, with no notable differences based on gender or age.
