Hepatitis C virus (HCV)/ coinfection is common in Egypt and other developing countries. This study aimed to investigate the influence of HCV/ coinfection on the concentration of HCV–nonstructural protein-4 (NS4) in addition to collagen III and matrix metalloproteinase-1 (MMP-1) in different hepatic fibrosis stages. We found that coinfected patients ( = 186) showed significantly ( < 0.05, Mann–Whitney test) higher concentrations of HCV-NS4, collagen III, and collagen III/MMP-1 ratio (CMR) than those with HCV monoinfection ( = 104) in different fibrosis stages. Conversely, coinfected patients showed significantly lower concentrations of MMP-1 when compared with HCV monoinfection. The elevated levels of CMR in case of HCV monoinfection yielded an estimated odds ratio of 1.8 and 2.6 for developing significant fibrosis (F2-F4) and cirrhosis (F4), respectively. HCV/ coinfection increased the risk for developing F2-F4 and F4 several fold yielding an estimated odds ratio of 11.1 and 5.2, respectively. This means that coinfected patients have a 6-fold and 2-fold increased risk of developing F2-F4 and F4, respectively, over HCV-monoinfected patients. Thus, elevated levels of HCV-NS4 and CMR in HCV/ coinfection suggest increased susceptibility of coinfected patients, compared with those with HCV monoinfection, for accelerating hepatic fibrosis progression.
