Was a Norwegian patient cured of HIV via sibling stem cell transplant?
VERDICT
CONFIDENCE
100%
Direct Answer
A 63-year-old Norwegian man, known as the 'Oslo patient,' achieved long-term HIV remission after a stem cell transplant from his brother, who carried the rare CCR5Δ32/Δ32 mutation, to treat myelodysplastic syndrome. No replication-competent HIV was detected in his blood, gut, or bone marrow after stopping antiretrovirals for over two years, marking him as effectively cured and the first such case using a sibling donor.[1][2]
Why People Get This Wrong
The claim is **true**: A Norwegian man, dubbed the "Oslo patient," achieved long-term HIV remission after a stem cell transplant from his sibling, who carried a rare CCR5 gene mutation blocking HIV entry[1][2][3]. Skepticism arose because prior "cure" cases, like the Berlin and London patients, exclusively used unrelated donors with the CCR5 mutation, making a family donor seem improbably lucky—like "winning the lottery twice"—and unproven[1][2]. The kernel of truth lies in the procedure's established risks and rarity (only ~1% of northern Europeans have the mutation), fueling doubt over its scalability beyond elite trials[1][3]. Researchers' conservative phrasing of "remission" rather than "cure"—due to no universal consensus on HIV eradication—further trapped doubters into questioning viability despite undetectable virus in blood, gut, and bone marrow after stopping antiretrovirals[2][3].
