It was a sad and disappointing turn of events: the kid known as the Mississippi child, in remission of HIV infection for much more than two many years right after discontinuation of antiretroviral treatment (Art), now has clear evidence of HIV rebound. The announcement will undoubtedly be viewed by some as a setback in the renewed quest for an HIV cure.
It doesn’t want to be. We require to take the highs and lows in our stride. We have a proof of idea that a cure for HIV is attainable in the Berlin Patient, Timothy Brown, who acquired a bone marrow transplant and remains virus free off therapy for more than six years.
We also have the situation of the French Visconti cohort, now comprising twenty HIV-positive men and women who have been taken care of very early with HIV medication, but then stopped treatment. Right after virtually ten many years off therapy, they are keeping the virus under tight manage.
Only one person, who is now in remission for a non Aids-connected cancer, reinitiated Artwork despite his HIV infection even now currently being controlled at the time that he obtained anti-cancer therapy.
The lows – if the Mississippi infant case can be called a reduced – provide main insights into the scientific problems that lie ahead for the researchers, scientists and others gathering at the Aids 2014 symposium in Melbourne this week.
Comparable to the Mississippi infant, the Boston patients – two guys who received bone marrow transplants that appeared to rid them fully of HIV – also relapsed, and are now back on antiretroviral treatment.
What has been most encouraging for all three sufferers was that the time the virus stayed beneath management off remedy, or in remission, was drastically longer than what we have ever witnessed before. The Boston patients were virus-free of charge for 12 and 32 weeks, and the Mississippi infant virus-totally free for a impressive 27 months.
Nevertheless, as we have discovered above the past 3 decades, HIV has many tricks up its sleeve.
An minute sum of virus – which none of our present exams are even shut to detecting – was capable to persist in these 3 patients and reappear at any time, with absolutely no warning.
The Mississippi baby, and the Boston sufferers, tell us that to attain extended phrase HIV remission we will likely need to have to tackle the difficulty on multiple fronts – lowering as much as attainable the quantity of extended-lived, latently contaminated cells existing in the entire body, as effectively as bolstering the host defence. 1 can not be carried out without the other.
We have usually known that the search for an HIV remedy wasn’t going to be easy. We have to be optimistic, and hope that situations like the Mississippi infant will demonstrate to be one more piece in the jigsaw puzzle that is an HIV remedy.
To attain this objective will need substantial academic collaboration as nicely as public-private partnerships that can drive innovative and effectively-funded strategic research over the prolonged term.
We have to proceed the search for an HIV remedy. We owe it to the 35m men and women living with HIV.
