NEW HOPE! A
‘FUNCTIONAL’ CURE FOR HIV / AIDS
According to the Southern Daily, Barcelona researchers
believe that blood transplants can rid the body of HIV. The aids-drugs Doctors
in Barcelona, Spain, announced they believe they’ve found a cure for HIV,
according to the Latin Post. But don’t hold your breath, it’s not going to be
available overnight.
Similar to the report published by Harvard researchers, the
Spanish research team hypothesizes that a blood transplant from a donor with a
genetic mutation could prevent HIV from entering cells and replicating.
The announcement is based on results of an experimental
treatment given to a 37-year-old man who contracted HIV in 2009. The “Barcelona
Patient” developed lymphoma in 2012. He received chemotherapy and a transplant
of blood from an umbilical cord of a donor who had a genetic mutation that gave
the donor a heightened resistance to HIV.
“We suggested a transplant of blood from an umbilical cord
but from someone who had the mutation because we knew from ‘the Berlin patient’
that as well as [ending] the cancer, we could also eradicate HIV,” Rafael
Duarte, the director of the Haematopoietic Transplant Programme at the Catalan
Oncology Institute in Barcelona, explained to Spanish news site The Local.
People with the CCR5 Delta 35 genetic mutation that leaves
them without CCR5 cellular receptors, which act like doorways to the cell. HIV
uses CCR5 receptors to enter white cells for replication. This heightened
resistance to HIV occurs in about 1 percent of the population.
The Spanish medical team sought to replicate the results of
Timothy Brown, an HIV-positive man dubbed “the Berlin Patient,” who received an
experimental bone marrow transplant from a donor with the mutation. Brown had
leukemia and HIV but six years later shows no signs of the virus.
The treatment seemed to work, as the Barcelona Patient was
HIV free after three months, but unfortunately died due to cancer. The
development spurred Spain’s National Transplant Organization to back the
world’s first clinical trials of umbilical cord blood transplants for HIV
patients with blood cancers, according to the Latin Post. Javier Martínez, a virologist
from the research foundation Irsicaixa, is quoted as saying that while their
trials are aimed at helping HIV-positive cancer patients but it could “allow us
to speculate about a cure for HIV.”
