Abstract
Background
HCV and HIV co-infected patients develop cirrhosis more rapidly than HCV mono-infection. Intestinal injury and microbial translocation are postulated mechanisms for the rapid progression of cirrhosis.
Aim
Study the effect of HCV treatment with DAAs on serum intestinal fatty acid binding protein (I-FABP) as a marker of intestinal injury in HCV/HIV co-infected patients and its relation to hepatic fibrosis. Comparing the level of I-FABP in HCV mono-infection and HCV/HIV co-infection was a secondary aim.
Methods
I-FABP levels were measured in 50 non-cirrhotic HCV/HIV co-infected patients pre- and post-HCV treatment (SVR 12) (25 patients were HIV treatment naive, and 25 patients were on HAART) and in 25 chronic HCV patients as a control group. Hepatic fibrosis was assessed by FIB4 score, APRI score, and transient elastography.
Results
HCV/HIV co-infected patients had significantly higher levels of I-FABP compared to the HCV-mono-infected patients (P = 0.001). After HCV treatment in HCV/HIV co-infected patients, I-FABP level was significantly elevated (P < 0.001) and was positively correlated with baseline FIB4 values and serum ALT levels (r = 0.283, P-value = 0.047) and (r = 0.340, P-value = 0.016), respectively.
Conclusion
HCV/HIV co-infection is associated with significantly higher intestinal injury and subsequent hepatic fibrosis than HCV mono-infection. HIV infection is associated with intestinal epithelial injury and microbial translocation and may play a role in the persistence of systemic inflammation after HCV eradication.
