The Essen/Berlin patient is a man who goes by the pseudonym Christian Hahn (see the Resources entry for the book CURED: How the Berlin Patients Defeated HIV and Forever Changed Medical Science) with Non-Hodgkin’s lymphoma, CCR5-tropic HIV infection, and the HLA-B*5701 protective mutation (see the HLA-B*5701 and HLA-B*2701 Glossary entry). Because of the poor prognosis for his lymphoma, he underwent a CCR5 Δ32/Δ32 bone-marrow transplant. However, following the transplant, he was found to have either CXCR4-tropicTropic and Tropism or dual CCR5- plus CXCR4-tropic HIV infection and subsequently died from a recurrence of his lymphoma. It is not well understood why the CXCR4- or dual-tropic HIV infection was not detected; it may have been simply because there were very, very few such virions. Alternately, the detection failure may have been because the patient’s particular lymphoma is an AIDS-defining condition, and progress to AIDS and some biological changes that occur in parts of CD4+ T cells’ gp120 spikes are the clinical factors most likely to predispose a transition from CCR5 tropism to CXCR4 tropism.
