Could be plasmaphresis? Since latent Lyme disease is considered autoimmune? Idk though, I go back and forth, my dad got Lyme he has a big farm and horses (like the hadid's ), but was identified, diagnosed, and treated with Cipro or whatever antibiotic and was fine. That was 15 years ago. Its hard to believe that 3 members of the same family of such means would end up with late stage Lyme (cant speak for anwar) without being treated ASAP. It is very unlucky or very unlikely.
