Background & Aim
Several factors involved in the development of liver fibrosis in African American patients with chronic hepatitis C (CHC) have not been well-studied. We aimed to evaluate some of these risk factors.
Methods
We reviewed pathology and medical records of 603 African Americans with chronic hepatitis C virus (HCV) infection at Howard University Hospital from Jan. 2004 to Dec. 2013. Among the clinical and pathological data collected were HIV (human immunodeficiency virus), HCV genotype, Hepatitis B virus (HBV), diabetes mellitus (DM), hypertension (HTN), body mass index (BMI), and hepatic steatosis.
Results
The frequency of DM, HTN, HIV and HBV were 22%, 16%, 11%, and 4%, respectively. Median BMI was 27.3 kg/m2. The frequency of fibrosis stages 0, 1, 2, 3 and 4 were 2%, 48%, 28%, 11% and 11%, respectively. In multivariate logistic regression, we found a significant association between liver fibrosis stage (3–4 vs. 0–2) and HIV infection (OR=2.4, P = 0.026), hypertension (OR=3.0, P = 0.001), age (OR=2.6 for every 10 years, P<0.001), weight (OR = 1.1 for every 10 pound increase, P = 0.002) and steatosis grade (OR = 1.6, P = 0.002). The frequency of liver steatosis was 73%. In an ordinal logistic regression, significant risk factors for steatosis were female gender (OR = 1.5, P = 0.034) and inflammation grade (P=0.001).
Conclusion
This study shows that steatosis is independently associated with fibrosis in African American patients with HCV infection. Female patients were at higher risk for steatosis.
