I have had success with a couple supplements called VRM3 & VRM4. The VRM3 is for girdiasis and microscopic parasites. The VRM4 is for cellular parasites specific for live and kidney flukes. So maybe those would be helpful for you. You can check them out at the links below.
They only sell their products to health care practitioners, but my chiropractor said he actually had a patient ask him to order them and has been using them ever since. It really helped me when nothing else did.
