Before his transfer to Yale, doctors elsewhere tried to identify the mysterious cause by performing multiple biopsies of his diseased skin. Tests were negative for bacterial or fungal pathogens. But they showed that his blood vessels were swollen and filled with clumps of immune cells. Doctors were concerned that her immune system was attacking her blood vessels, causing necrotic lesions. So, they gave him immunosuppressant drugs. But his condition worsened and the wounds increased. When he arrived at Yale, he had a fever, a rapid heart rate, and looked weak. He had lost 16 pounds and was drowsy and confused. He was covered with wounds.
Yale doctors noted that the lesions began after his return from Florida, where he spent the winter. While there, he was exposed to red tide (caused by algae) while cleaning up after a storm. Otherwise, he had a medical history only of nasal polyps and asthma, which he treated with the monoclonal antibody drug, dupilumab. Noticing that her lesions continued to grow, they performed a skin biopsy again, this time finding amoeba-like cells. Confirmed by DNA test acanthamoeba.
Doctors immediately put her on a regimen of five drugs recommended for such infections by the Centers for Disease Control and Prevention, but her condition continued to worsen. He then sought and received approval from the Food and Drug Administration for a single-patient experimental trial of an antibiotic (nitroxoline), which had shown success in treating a different amoeba in a second patient. Once doctors introduced it into humans, it seemed to work. His fever broke for a while, some of his wounds improved and no new wounds formed.
