Causes of minimal hepatic periportal fibrosis present in Egypt.

: This study aimed to elucidate the common causes of minimal periportal fibrosis in Egypt. Out of 50 patients having minimal periportal fibrosis, 22 (44%) had schistosomiasis as a sole aetiology, 33 (66%) had combined schistosomiasis with both HBV and HCV. Rare causes were tuberculosis in 4% of the patients and HIV in 2%. No cause could be elicited in 14% of the patients. It is concluded that although schistosomiasis is the commonest cause of minimal hepatic fibrosis in Egypt, yet it is not the sole aetiological factor.
