Downregulation of MIP-1α/CCL3 with praziquantel treatment in Schistosoma haematobium and HIV-1 co-infected individuals in a rural community in Zimbabwe

The results of our study show that the MIP-1alpha/CCL3 levels were positively associated with S. haematobium egg counts at baseline but not with HIV-1 infection status. MIP-1alpha/CCL3 levels were significantly reduced at three months post treatment with praziquantel. We therefore conclude that MIP-1alpha/CCL3 is produced during infection with S haematobium. S. haematobium infection is associated with increased MIP-1alpha/CCL3 levels in an egg intensity-dependent manner and treatment of S. haematobium is associated with a reduction in MIP-1alpha/CCL3
