Blau, M.D., Wolf K. Hofmann, M.D., and Eckhard Thiel, M.D.: Brief Record: Long-Term Control of HIV by CCR5 Delta32/Delta32 Stem-Cell Transplantation HIV-1 enters sponsor cells by binding to a CD4 receptor and interacting with either CCR5 or the CXC chemokine receptor . Homozygosity for a 32-bp deletion in the CCR5 allele results in an inactive CCR5 gene item and therefore confers high resistance against HIV-1 acquisition.1 Allogeneic stem-cell transplantation from an HLA-matched donor is a feasible option for sufferers with hematologic neoplasms, but it is not established as a therapeutic option for patients who are also contaminated with HIV.2 Survival of patients with HIV infection has improved considerably since the introduction of highly energetic antiretroviral therapy ,3 and as a result, successful allogeneic stem-cell transplantation with ongoing HAART was performed in 2000.4 In this report, the outcome is described by us of allogeneic stem-cell transplantation in a patient with HIV infection and acute myeloid leukemia, utilizing a transplant from an HLA-matched, unrelated donor who was simply screened for homozygosity for the CCR5 delta32 deletion.However, dacarbazine is still used as a first-series therapy for metastatic melanoma in many countries. An additional phase 3 research , evaluating both nivolumab mixture and monotherapy therapy with nivolumab plus ipilimumab, in comparison with ipilimumab alone, in untreated patients with melanoma happens to be under way previously. The experience of ipilimumab is most likely reflected in the overall performance of the dacarbazine group in today’s research.
