The case of the “new affected person in Berlin” raises hope for a profitable remedy for AIDS

A 60-year-old German seems to be the seventh individual to obtain an efficient HIV treatment after present process a stem cell transplant, medical doctors introduced Thursday.

The painful and harmful process is reserved for folks with HIV and aggressive leukemia, so it’s not an choice for the roughly 40 million folks residing with the lethal virus worldwide.

The German man, who wished to stay nameless, was named “Berlin’s new affected person.”

The unique Berlin affected person, Timothy Ray Brown, was the primary individual to be declared cured of HIV in 2008. Brown died of most cancers in 2020, the second Berliner to be recognized with HIV. A treatment shall be introduced earlier than the twenty fifth Worldwide AIDS Convention in Munich, Germany subsequent week. He was first recognized with HIV in 2009, in accordance with a abstract of the analysis introduced on the convention.

However greater than 5 years signifies that the individual shall be “shut” to being cured.

All however one of many different sufferers obtained stem cells from donors with a uncommon mutation wherein a part of the CCR5 gene was lacking, which prevented HIV from into the physique’s cells.

These donors inherited two copies of the mutated CCR5 gene — one from every dad or mum — making them “just about immune” to HIV, Lewin stated.

However the brand new affected person in Berlin is the primary to obtain stem cells from a donor who inherited just one copy of the mutated gene.
