The study aimed to determine adjusted all-cause mortality and cause of death in persons with chronic hepatitis B virus (HBV) infection compared with age- and sex-matched persons from the general population. We used nationwide registers to identify persons aged >= 18 years with chronic HBV infection in 2002-2017 in Denmark and included 10 age- and sex-matched controls for each. Follow-up was from 6 months after diagnosis until death, emigration, or 31 December 2017. Mortality rate ratios (MRRs) adjusted for age, sex, employment, origin and comorbidity were calculated using Poisson regression. Unadjusted cause-specific mortality rate ratios with 95% confidence intervals were calculated assuming a Poisson distribution. A total of 6988 persons with chronic HBV infection and 69,847 controls were included. During a median follow-up of 7.7 years (range 0.0-15.5), 315 (5%) persons with-and 1525 (2%) without-chronic HBV infection died. The adjusted all-cause MRR was 1.5 (95% CI 1.2-2.0). Persons with chronic HBV infection had increased mortality due to liver disease including hepatocellular carcinoma (MRR 12.3 [8.6-17.7]), external causes (MRR 3.3 [2.5-4.7]), endocrine disease (MRR 3.2 [1.8-5.4]), genitourinary disease (MRR 3.2 [1.2-7.6]) and neoplasms (except hepatocellular carcinoma; MRR 1.6 [1.2-2.0]). In conclusion, this study showed an increased all-cause mortality in persons with chronic HBV infection in comparison with age- and sex-matched persons without chronic HBV infection which remained after adjustment for several confounding factors. Excess mortality was mainly associated with liver disease, but also external factors, endocrine disease, genitourinary disease and neoplasms (excluding hepatocellular carcinoma).

Objective: Data on the risk of ischemic heart disease (IHD) in patients with chronic hepatitis B virus (CHB) are conflicting. Our objective was to address the rate of IHD in patients with CHB compared with individuals without CHB (control-persons) from the general population. Study Design and Setting: We conducted a cohort study of prospectively obtained data from Danish nationwide registries. We produced cumulative incidence curves and calculated the unadjusted incidence rate ratio (IRR) of IHD in persons with and without CHB. The adjusted association between having CHB and developing IHD was examined using a cause-specific Cox regression model. Results: In total, 6472 persons with CHB and 62,251 age-and sex-matched individuals from the general population were followed for 48,840 and 567,456 person-years, respectively, during which 103 (1,59%) with CHB and 1058 (1,70%) control-persons developed IHD. The crude IRR was 1.13 (95% CI: 0.91–1.39). CHB did not have a statistically significant effect on the rate of IHD after adjusting for several confounding factors (adjusted hazard ratio: 0.96, 95% CI: 0.76–1.21). Conclusion: In this nationwide cohort study, we did not find any difference between rate of IHD in persons with CHB in comparison with the general population.

Purpose: We aimed to determine incidence of hepatocellular carcinoma (HCC) and decompensated liver cirrhosis in persons with chronic hepatitis B virus (HBV) infection in Denmark stratified by disease phase, liver cirrhosis, and treatment status at baseline. Additionally, we aimed to assess the prognostic value of the PAGE-B HCC risk score in a mainly non-cirrhotic population. Patients and Methods: In this register-based cohort study, we included all individuals over the age of 18, with chronic HBV infection first registered between 2002 and 2016 in at least one of three nationwide registers. The study population was followed until HCC, decompensated liver cirrhosis, death, emigration, or December 31, 2017, which ever came first. Results: Among 6016 individuals included in the study, 10 individuals with and 23 without baseline liver cirrhosis developed HCC during a median follow up of 7.3 years (range 0.0-15.5). This corresponded to five-year cumulative incidences of 7.1% (95% confidence interval (CI) 2.0-12.3) and 0.2% (95% CI 0.1-0.4) in persons with and without baseline liver cirrhosis. The five-year cumulative incidence of decompensated liver cirrhosis was 0.7% (95% CI 0.5-1.0). Among 2038 evaluated for liver events stratified by disease phase, incidence of HCC was low in all who were non-cirrhotic and untreated for HBV at baseline. PAGE-B score was evaluated in 1529 persons. The 5-year cumulative incidence of HCC was 0, 0.8 (95% CI 0.5-1.8), and 8.7 (95% CI 1.0-16.4) in persons scoring 17, respectively (c-statistic 0.91 (95% CI 0.84-0.98)). Conclusion: We found low incidence of HCC and decompensated liver cirrhosis in persons with chronic HBV infection in Denmark. Moreover, the PAGE-B score showed good accuracy for five-year risk of developing HCC in the population with chronic HBV infection in Denmark.

Objective: To evaluate implementation of national guideline recommendations on treatment initiation for chronic hepatitis B (CHB) in Denmark. Methods: Using DANHEP, a nationwide cohort of chronic hepatitis B and C patients attending specialized hospital care in Denmark, we performed a descriptive cohort study from January 2002 through December 2017. We identified patients with CHB in 3 of 5 Danish regions, with at least two hospital/outpatient clinic visits during the study period. Results: We identified 990 CHB patients who remained untreated throughout the study period, and 265 who initiated treatment. At their last visit 952/990 (96%, 95% CI 95–97) untreated patients did not meet current national criteria for treatment initiation while 198/265 (75%, 95% CI 69–80) who initiated treatment met the national criteria. Overall, 198/236 (84%, 95% CI 79–88) who met national treatment criteria, initiated treatment. Conclusion: The majority of CHB patients received care in line with national guideline recommendations for treatment initiation. We found that only few patients eligible for treatment remained untreated. However, a fourth of patients who received treatment were not eligible according to national guidelines.

Background: Early identification of patients with chronic viral hepatitis coinfected with human immunodeficiency virus (HIV) is essential for optimal care. The objectives of this study were to estimate the prevalence of HIV coinfection among patients newly diagnosed with chronic viral hepatitis, HIV testing prevalence, and identify factors associated with coinfection.Methods: Patients with chronic viral hepatitis newly enrolled in The Danish Database for Hepatitis B and C between 2002 and 2015 were identified. The HIV coinfection prevalence was calculated, and risk factors associated with HIV coinfection were estimated by logistic regression.Results: In total, 8490 patients were included: 3091 had chronic hepatitis B (CHB), 5305 had chronic hepatitis C (CHC), and 94 had CHB and CHC. The prevalence of HIV coinfection was 4.4% (95% confidence interval [CI], 4.0-4.9) and was higher among CHC and CHB-CHC patients than CHB patients with a prevalence of 5.3% (95% CI, 4.7-5.9), 6.4% (95% CI, 2.4-13.4), and 2.9 (95% CI, 2.3-3.5), respectively (P < .0001). The HIV testing prevalence increased from 65% to 88% between 2002 and 2014 concurrently with a decrease in the HIV coinfection prevalence from 7.8% (95% CI, 5.5-10.7) to 1.6% (95% CI, 0.7-3.2). Age 35-50 years, male sex, and sexual route of viral hepatitis transmission were associated with HIV coinfection with odds ratios of 4.42 (95% CI, 1.40-13.94), 2.21 (95% CI, 1.74-2.81), and 8.81 (95% CI, 6.30-12.33), respectively.Conclusions: The prevalence of HIV coinfection among patients with newly diagnosed chronic viral hepatitis decreased concurrently with an increase in HIV testing prevalence.

BACKGROUND AND AIMS: Chronic hepatitis C virus (HCV) genotype 3 infection with advanced liver disease has emerged as the most challenging to treat. We retrospectively assessed the treatment outcome of sofosbuvir (SOF) based regimes for treatment of HCV genotype 3 infections in a real life setting in Scandinavia.METHODS: Consecutive patients with chronic HCV genotype 3 infection were enrolled at 16 treatment centers in Denmark, Sweden, Norway and Finland. Patients who had received a SOF containing regimen were included. The fibrosis stage was evaluated by liver biopsy or transient liver elastography. The following treatments were given according availability and local guidelines: 1) SOF + ribavirin (RBV) for 24 weeks, 2) SOF + daclatasvir (DCV) +/-RBV for 12-24 weeks, 3) SOF + pegylated interferon alpha (peg-IFN-α) + RBV for 12 weeks or 4) SOF/ledipasvir (LDV) + RBV for 12-16 weeks. The primary endpoint was sustained virological response (SVR) assessed at week 12 (SVR12) after end of treatment.RESULTS: We included 316 patients with a mean age of 55 years (range 24-79), 70% men, 49% treatment experienced, 58% with compensated cirrhosis and 12% with decompensated cirrhosis.In the modified intention to treat (mITT) population SVR12 was achieved in 284/311 (91%) patients. Among 26 treatment failures, five had non-response, 3 breakthrough and 18 relapse. Five patients were not included in the mITT population. Three patients died from reasons unrelated to treatment and two were lost to follow-up. The SVR12 rate was similar for all treatment regimens, but lower in men (p = 0.042), and in patients with decompensated liver disease (p = 0.004).CONCLUSION: We found that sofosbuvir based treatment in a real-life setting could offer SVR rates exceeding 90% in patients with HCV genotype 3 infection and advanced liver disease.
