Dataset Information

Liver disease symptoms are associated with higher risk of adverse clinical outcomes: A longitudinal study of North American adults with chronic Hepatitis B.

ABSTRACT:

Background

Symptoms of chronic hepatitis B (CHB) are not well characterized.

Aims

To evaluate CHB symptoms and associations with disease activity and clinical outcomes.

Methods

Longitudinal data from 1,576 participants in the Hepatitis B Research Network Cohort Study who completed symptom assessments were analyzed. A composite symptom score was calculated using a Symptom Checklist (0=none to 40=extreme). Multivariable mixed models assessed variables associated with symptom change over time. Latent class symptom trajectories were evaluated. The cumulative probability of long-term clinical outcomes (new onset cirrhosis, hepatic decompensation, hepatocellular carcinoma, liver transplantation, death) was examined by baseline symptom groups.

Results

Participants median age was 42 (range:18-80), 51% were male, 75% Asian, (68% of whom were born outside North America) with a median follow-up of 4.2 years. On average, symptoms did not significantly change over time. The multivariable model identified several variables associated with higher symptoms during follow-up: being female, non-Asian, born in the US/Canada, lower education, higher AST, lower platelets, and more comorbidities. Two patient subgroups were identified based on longitudinal symptom trajectories: a low symptom group (92%, n=1,451) with symptom scores averaging 2.4 over time and a moderate symptom group (8%, n=125) with symptom scores averaging 11.5. During follow-up, 7.3% in the moderate symptom group, but only 3.2% of the low symptom group, developed adverse outcomes (p=0.02).

Conclusions

In this large cohort of CHB patients, symptoms were generally mild and stable over time. However, in some patients with moderate symptoms at baseline, deleterious clinical outcomes were more frequent in follow-up.

Project description:INTRODUCTION:Patients with hepatitis B early antigen (HBeAg)-negative chronic hepatitis B (CHB) and low-level viremia are a heterogeneous group. Identifying those at risk of developing active CHB requiring antiviral therapy is important. In this study, we prospectively characterize incidence rates and predictors of transitioning from inactive to active CHB in a North American adult cohort. METHODS:Participants in the multicenter National Institute of Diabetes and Digestive and Kidney Diseases Hepatitis B Research Network cohort who were HBeAg negative with baseline hepatitis B virus (HBV) DNA ≤ 10,000 IU/mL were included in the study. Cox regression models were used to estimate the proportion of individuals in 3 baseline HBV DNA categories (≤100, 101 to ≤2,000, and 2,001 to ≤10,000 IU/mL) who developed phase transition defined by HBV DNA > 10,000 IU/mL and alanine aminotransferase (ALT) > 2× upper limit of normal or initiated treatment during follow-up. RESULTS:Of 970 participants meeting inclusion criteria, 15% experienced phase transition or initiated treatment over a median follow-up of 4 years: 9% of those with baseline HBV DNA ≤ 100 IU/mL, 14% with HBV DNA 101 to ≤2,000 IU/mL, and 24% with HBV DNA 2,001 to ≤10,000 IU/mL (P < 0.001). The overall rate of phase transition or treatment initiation was 7.6 per 100 person-years: 4.6 in those with HBV DNA ≤ 100 IU/mL, 6.8 in those with HBV DNA 101 to ≤2,000 IU/mL, and 12.2 in those with HBV DNA 2,001 to ≤10,000 IU/mL (P < 0.001). Factors independently associated with higher rate of phase transition or treatment initiation included HBV genotype B or C, higher baseline ALT and HBV DNA levels, lower platelet count, quantitative hepatitis B surface antigen > 1,000 IU/mL, and hyperlipidemia. Only higher ALT, higher HBV DNA, and lower platelets were associated with phase transition when patients starting treatment were censored. DISCUSSION:Most adults in this North American cohort with HBeAg-negative CHB and low-level viremia remained inactive and off treatment over 4 years. Transition from inactive to active CHB is infrequent and predominantly associated with viral rather than host factors.
