P-35 CLINICAL AND EPIDEMIOLOGICAL DIFFERENCES BETWEEN PATIENTS MONOINFECTED WITH HEPATITIS B AND COINFECTED WITH HEPATITIS DELTA IN A HYPERENDEMIC REGION OF HEPATITIS B

No Hepatitis B and co-infection with hepatitis delta are viral liver diseases that can rapidly progress to cirrhosis and hepatocellular carcinoma (HCC). Objectives: To compare the epidemiological profile between patients mono-infected with hepatitis B and patients co-infected with hepatitis B and delta in a hyperendemic region. A cross-sectional and historical cohort study analyzing 286 medical records of co-infected individuals and 649 medical records of mono-infected. Variables: sex, age, stage of liver fibrosis, levels of liver enzymes, albumin, platelets, alpha-fetoprotein, presence of HCC, and outcomes (liver transplant or death). Of the 286 co-infected, 189 (70.5%) were male, mean age 56 ± 19. About stage of fibrosis, 97 (34%) had no fibrosis, 163 (57%) had (F1F3), and 26 (9%) had cirrhosis (F4). Mean GGT were 64.6 ± 86.6 U/L, ALT 36.2 ± 33.1 U/L, AST 41.2 ± 61.1 U/L, albumin 4.1 ± 0.75 g/dL, platelets 192 ± 77 thousand/mm³, alpha-fetoprotein 122.7 ± 181.1 ng/mL. 12 (4.2%) developed HCC, mean age of 53 ± 11.8; 8 (2.8%) underwent liver transplantation, and 22 (7.7%) died. Of the 659 mono-infected, 449 (68.14%) were male, mean age 53 ± 12.7. About stage of fibrosis, 248 (36%) had no fibrosis, 335 (48.69%) had fibrosis (F1F3), and 105 (15.26%) had cirrhosis (F4). Mean GGT were 64.4 ± 85.9 U/L, ALT 36.2 ± 33.8 U/L, AST 40.7 ± 59.9 U/L, albumin 4.19 ± 0.74 g/dL, platelets 3.27 ± 3.4 thousand/mm³, alpha-fetoprotein 117.6 ± 2133.5 ng/mL. 31 (4.7%) developed HCC, mean age of 57.4 ± 12.6; 18 (2.7%) died. Co-infected patients have a higher prevalence of liver fibrosis and develop HCC at a younger age. There was statistical significance in platelet count, indicating greater severity of liver dysfunction in the mono-infected group.
