Aim: This study aimed to verify the relationship between the insertion-deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) and clinical and histological correlates of chronic hepatitis C. Methods: Two-hundred and fifty-eight, treatment naive, unselected hepatitis C virus (HCV) RNA-positive patients and 210 controls were studied. ACE allelic variants were determined by polymerase chain reaction. Results: Mean staging scores adjusted for age, body mass index (BMI) and alcohol consumption were: men, D/* = 2.283; men, I/I = 2.092; women, D/* = 2.241; and women, I/I = 3.283 (P = 0.028). Age-adjusted mean BMI were: men, D/* = 25.01; men, I/I = 24.87; women, D/* = 23.73; and women, I/I = 22.50 (P = 0.006). Age and BMI-adjusted mean low-density lipoprotein (LDL)/ high-density lipoprotein (HDL) cholesterol ratios were: men, D/* = 2.344; men, I/I = 2.283; women, D/* = 1.916; and women, I/I = 1.903 (P = 0.004). Histological grading correlated positively with triglycerides and negatively with HDL and LDL cholesterol (P < 0.0001). Conclusion: Female ACE I/I homozygotes have higher liver fibrosis scores in comparison to D/* women and to men; moreover, they are leaner and have a lower LDL/HDL cholesterol ratio. These observations suggest a possible mutual influence between ACE polymorphism, serum lipid concentrations and outcome of chronic HCV infection.

Abstract

Aim: This study aimed to verify the relationship between the insertion-deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) and clinical and histological correlates of chronic hepatitis C. Methods: Two-hundred and fifty-eight, treatment naive, unselected hepatitis C virus (HCV) RNA-positive patients and 210 controls were studied. ACE allelic variants were determined by polymerase chain reaction. Results: Mean staging scores adjusted for age, body mass index (BMI) and alcohol consumption were: men, D/* = 2.283; men, I/I = 2.092; women, D/* = 2.241; and women, I/I = 3.283 (P = 0.028). Age-adjusted mean BMI were: men, D/* = 25.01; men, I/I = 24.87; women, D/* = 23.73; and women, I/I = 22.50 (P = 0.006). Age and BMI-adjusted mean low-density lipoprotein (LDL)/ high-density lipoprotein (HDL) cholesterol ratios were: men, D/* = 2.344; men, I/I = 2.283; women, D/* = 1.916; and women, I/I = 1.903 (P = 0.004). Histological grading correlated positively with triglycerides and negatively with HDL and LDL cholesterol (P < 0.0001). Conclusion: Female ACE I/I homozygotes have higher liver fibrosis scores in comparison to D/* women and to men; moreover, they are leaner and have a lower LDL/HDL cholesterol ratio. These observations suggest a possible mutual influence between ACE polymorphism, serum lipid concentrations and outcome of chronic HCV infection.
