Of particular interest were AEs that could be associated with geohelminth infections: low haemoglobin (intestinal blood loss caused by adult worms); eosinophilia (parasite infection); and elevation of alkaline phosphatase (ALP) and the liver transaminases alanine aminotransferase (ALT) and aspartate aminotransferase (AST; migration of helminth larvae in the liver/liver function). Here, GPT is linked to parasitic infectious disease.
