Integrating Management of Hepatitis C Infection into Primary Care: the Key to Hepatitis C Elimination Efforts.

Elimination of hepatitis C virus (HCV), a leading cause of liver disease in the USA and globally, has been made possible with the advent of highly efficacious direct acting antivirals (DAAs). DAA regimens offer cure of HCV with 8-12 weeks of a well-tolerated once daily therapy. With increasingly straightforward diagnostic and treatment algorithms, HCV infection can be managed not only by specialists, but also by primary care providers. Engaging primary care providers greatly increases capacity to diagnose and treat chronic HCV and ultimately make HCV elimination a reality. However, barriers remain at each step in the HCV cascade of care from screening to evaluation and treatment. Since primary care is at the forefront of patient contact, it represents the ideal place to concentrate efforts to identify barriers and implement solutions to achieve universal HCV screening and increase curative treatment.

Disparities in presentation and management of chronic hepatitis B among Hispanics in a diverse safety net system.

BACKGROUND: Chronic hepatitis B (HBV) prevalence is highest in foreign-born Asian and African individuals in the US, though Hispanics make up the largest proportion of the immigrant population. Differences in the diagnosis and management of chronic HBV in Hispanics might exist due to the lower awareness of risk. We aim to examine racial/ethnic disparities in the diagnosis, presentation, and immediate management of chronic HBV in a diverse safety net system enriched for Hispanics. METHODS: In a large urban safety-net hospital system, we retrospectively identified patients with chronic HBV by serological data and categorized them into mutually exclusive self-identified racial/ethnic groups: Hispanics, Asians, Blacks, and Whites. We then examined differences in screening, disease phenotype and severity, follow-up testing, and referral by race/ethnicity. RESULTS: Among 1063 patients, 302 (28%) were Hispanics, 569 (54%) Asians, 161 (15%) Blacks, and 31 (3%) Whites. More Hispanics (30%) were screened in the acute setting (defined as inpatient or emergency department encounters) than Asians (13%), Blacks (17%), or Whites (23%) (p<0.01). Hispanics also had lower rates of follow-up testing after HBV diagnosis than Asians including HBeAg status (43% vs. 60%, p<0.01) and HBV DNA levels (42% vs. 58%, p<0.01) and lower rates of linkage to specialty care (32% vs. 55%, p<0.01). Among those with available testing, however, the presence of immune-active chronic HBV was infrequent and similar across racial/ethnic groups. 25% of Hispanics had cirrhosis at initial presentation, proportionally higher than other groups (p<0.01). CONCLUSION: Our results underscore the importance of raising chronic HBV awareness and increasing both screening and linkage to care among Hispanic immigrants in addition to the existing risk groups, with the goal of mitigating downstream liver-related complications.
