In a groundbreaking medical development, a 60-year-old German man has potentially become the seventh person in the world to be cured of HIV after undergoing a stem cell transplant. This risky and painful procedure is typically reserved for individuals who have both HIV and aggressive leukaemia, making it a treatment option for only a small fraction of the nearly 40 million people worldwide living with the dreaded virus.
Initially wishing to remain anonymous, the German man who has now been dubbed the “next Berlin patient” underwent a process similar to that of the original Berlin patient, Timothy Ray Brown, who was the first person to be officially declared cured of HIV back in 2008. Unfortunately, Brown succumbed to cancer in 2020. The medical breakthrough was revealed just before the start of the 25th International AIDS Conference set to take place in Munich, Germany next week.
This new Berlin patient was diagnosed with HIV in 2009 and went on to receive a bone marrow transplant for his leukaemia in 2015. Subsequently, he discontinued taking anti-retroviral drugs, which are commonly used to reduce HIV levels in the blood, in late 2018. Nearly six years later, he is showing no signs of either HIV or cancer, according to medical researchers.
The uniqueness of this case lies in the fact that the stem cells were sourced from a donor with only one copy of the mutated CCR5 gene, as opposed to the traditional two copies found in other successful cases. With approximately 15 percent of individuals of European descent carrying this mutated gene, compared to just one percent with both copies, researchers are hopeful that this breakthrough will expand the potential donor pool for future treatments.
This recent success has provided a glimmer of hope in the ongoing search for a universal cure for HIV that would benefit all patients. The fact that complete elimination of the CCR5 gene may not be necessary for gene therapy to be effective opens up new possibilities and avenues for research in the field of HIV treatment.
Despite the optimism surrounding this case, medical experts remain cautious in their assessments. While the patient has shown remarkable progress and is currently in remission for more than five years, the long-term implications and permanence of this cure are yet to be determined. The uncertainty surrounding the timeline for monitoring cases like these makes it challenging to definitively declare a cure.
Nonetheless, the latest developments in HIV research are paving the way for future advancements and breakthroughs in the field of medical science. Each new case brings with it valuable insights and learnings that contribute to the ongoing efforts to combat and ultimately eradicate HIV on a global scale. As researchers continue to push the boundaries of what is possible, the hope for a world free of HIV grows stronger.
