Adherence to anti-viral treatment for chronic hepatitis B

Adherence to treatment of chronic Hepatitis B Virus (HBV) is an important issue and can affect the complication rate. Nucleos(t)ide analogue as oral treatments are used for patients with necro-inflammatory activity and high viral load, with the goal of decline the complication rate such cirrhosis and hepatic cancer. We aimed to investigate the adherence to chronic HBV treatment. Chronic HBV patients with dispensing medication rates (DMR) of at least 80% were defined as high adherence group (HAG) and those who dispensed less than 80% as low adherence group (LAG). The study included 273 patients. 90 patients (33%) were in the LAG and 183 (67%) in the HAG. The All-cause mortality in the LAG was 15.6%, and 8.7% among the HAG (p-value = 0.09). 185 patients were of Jewish origin (mean age of 52.96 ±14.6 years, 30% women) and 88 patients of Arab Bedouin (AB) origin (mean age of 40.86 ± 13.96 years (p-value < 0.001), 42% women). The proportion of Jewish patients with high adherence was 71% (131 patients) versus 59% (52 patients) in AB patients (p-value = 0.054). The all-causes mortality was 14.6% among Jewish origin and 3.4% of AB (p-value = 0.01). We conclude that, two third of HBV carriers are with high level adherence to treatment in southern Israel, with lower but marginally significant all-cause mortality. No-significant differences in adherence patterns were noted between Arab Bedouin and Jews.
