Surveillance programs for chronic viral hepatitis in three health departments.

Although chronic hepatitis B and chronic hepatitis C are diseases of public health importance, only a few health departments nationally have chronic viral hepatitis under surveillance; these programs rely primarily on direct reporting by medical laboratories. We conducted an evaluation to determine if lessons from these programs can guide other health departments. Between December 2002 and February 2003, we visited the Connecticut Department of Public Health, the Multnomah County Health Department in Portland, Oregon, and the Minnesota Department of Health to determine the capacity of their chronic hepatitis registries to monitor trends and provide case management. We found that the registries facilitated investigations of potentially acute cases by identifying previously known infections, and aided prevention planning by pinpointing areas where viral hepatitis was being diagnosed. For chronic cases, case management (defined as the process of ensuring that infected individuals and their partners receive medical evaluation, counseling, vaccination, and referral to specialists for treatment when indicated) was provided for hepatitis B in Multnomah County, but was limited in other programs; barriers included resource constraints, difficulties confirming chronic infection, and privacy concerns. Finding innovative ways to overcome these barriers and improve case management is important if chronic hepatitis surveillance is to realize its full potential.

Increased risk of acute hepatitis B among adults with diagnosed diabetes mellitus.

INTRODUCTION: The risk of acute hepatitis B among adults with diabetes mellitus is unknown. We investigated the association between diagnosed diabetes and acute hepatitis B. METHODS: Confirmed acute hepatitis B cases were reported in 2009-2010 to eight Emerging Infections Program (EIP) sites; diagnosed diabetes status was determined. Behavioral Risk Factor Surveillance System respondents residing in EIP sites comprised the comparison group. Odds ratios (ORs) comparing acute hepatitis B among adults with diagnosed diabetes versus without diagnosed diabetes were determined by multivariate logistic regression, adjusting for age, sex, and race/ethnicity, and stratified by the presence or absence of risk behaviors for hepatitis B virus (HBV) infection. RESULTS: During 2009-2010, EIP sites reported 865 eligible acute hepatitis B cases among persons aged ≥23 years; 95 (11.0%) had diagnosed diabetes. Comparison group diabetes prevalence was 9.1%. Among adults without hepatitis B risk behaviors and with reported diabetes status, the OR for acute hepatitis B comparing adults with and without diabetes was 1.9 (95% confidence interval [CI] = 1.4, 2.6); ORs for adults ages 23-59 and ≥60 years were 2.1 (95% CI = 1.6, 2.8) and 1.5 (95% = CI 0.9, 2.5), respectively. CONCLUSIONS: Diabetes was independently associated with an increased risk for acute hepatitis B among adults without HBV risk behaviors.
