Why we shouldn't say we have a "cure" for HIV until it's really true

The Berlin patient, Timothy Ray Brown, is historically unique - he is the only person ever truly cured of HIV. 

But in recent years scientific journals and the popular press alike have published multiple claims of HIV cures. From the French "functional cure" to the Mississippi baby, we have seen the word "cure" used a lot -- as well as vague synonyms for it like "cleared" and "HIV-free" -- and yet each time we've had to walk the hype back. 

Check out my new post over at The Conversation on why we shouldn't overhype HIV "cures."

Doctors Should Not Deny Ebola Patients CPR

The first time I did CPR, coagulated blood spurted onto my new white coat from a wound in the patient’s chest. Another time a patient’s urine soaked through the knees of my pants as I knelt at his side.

Even in the best of conditions, cardiopulmonary resuscitation (CPR) is a spit-smeared, bloody business that can expose health care workers to all kinds of body fluids. Like all health care workers, I put on gloves and a game face and accept such things as part of patient care.

The 2014 Ebola outbreak changes all that. It is much more dangerous for clinicians to resuscitate patients with Ebola. As a result, should we skip CPR altogether? Bioethicist Joseph Fins of the Weill Medical College of Cornell University recently suggested we should.

I disagree. See my rebuttal at Health Affairs. What do you think?

Top 10 trends in HIV this year

This year we have seen palpable progress in the fight against AIDS, and also some astonishing hucksterism. In celebration of World AIDS Day 2014, here are 10 of the most influential trends in HIV this year. 

WAD2014.jpg

1. The cure, and its pretenders. To date only one person has ever been cured of HIV infection: Timothy Ray Brown, a resident of Berlin who received a CCR5-deleted bone marrow transplant while on potent anti-HIV medications. Recently we heard the word "cure" applied frequently but ultimately falsely to the Mississippi baby and some patients given ordinary bone marrow transplants. Everyone but Timothy has relapsed. Next year let's use the "C" word with caution, and for a great book on the search for a cure, try Cured: How the Berlin Patients Defeated HIV and Forever Changed Medical Science by Nat Holt. 

2. A new model for AIDS. As I summarized in the Scientific American, Warner Greene's lab unleashed simultaneous papers in Science and Nature in late 2013 that upend how we understand the pathogenesis of AIDS. Through a stroke of luck reminiscent of the early identification of AZT - in which a promising new drug was already sitting on the shelf as a result of unrelated cancer research - Greene's group even moved a promising new approach to HIV treatment into clinical trials.

3. Better ART. Speaking of antiretroviral therapy (ART), the three-in-one antiretroviral drug Atripla has long been king of the HIV treatment hill. This changed with the late 2013 publication of the SINGLE trial in which a new combination drug (dolutegravir/abacavir/lamivudine) was safer and more effective than Atripla. This - and other similar studies in new HIV treatment options - has driven yet another shift in HIV treatment as patients have more and more ways of living long lives on good HIV medicine. This is cause for celebration, but we should not forget that most people with HIV can't access these treatments for one reason or another.

4. Do we really need all those CD4's? For years doctors have checked CD4 counts with every clinical visit, and patients have grown accustomed to that regular gauge on how they're doing. Yet as life expectancy on antiretroviral therapy gets longer and clinical visits become less frequent, many HIV docs have realized those faithfully-plotted CD4 counts aren't guiding our decisions for patients with suppressed HIV viral loads and strong immune systems. As a result, new guidelines make CD4 count monitoring "optional" for some patients - and I think it should be optional for more. 

5. Hope for hepatitis C. HIV treatment successes weren't the only reason for hope this year. Drug development for hepatitis C has also progressed dizzyingly quickly. Multiple new effective regimens have been released recently, including some with equivalently near-perfect efficacy in people with HIV. Treatment is still complicated, but when the smoke clears and we work out the considerable financial obstacles to widespread treatment, many expect these potent new drugs to put a huge dent in the hepatitis C epidemic.

6. The high potential and personal politics of PrEP. A key recent boon to the fight against AIDS has been the discovery that HIV drugs can safely protect many high risk people from HIV infection. In a huge boon to HIV prevention, pre-exposure prophylaxis (PrEP) has been proven to protect men who have sex with men, heterosexual men and women, and people who inject drugs from HIV. Recent WHO guidelines suggested "All men who have sex with men should have the opportunity to choose PrEP if they feel that it meets their HIV prevention needs" whereas the CDC guidelines recommended PrEP to groups that hew more closely to populations in whom PrEP showed proven protection. Political commentary has been plentiful, and new clarified WHO guidelines are due out soon, so the PrEP conversation is sure to rage on.

7. A shot in the arm for vaccines. Many HIV vaccine candidates have fizzled out in clinical trials, including the much-lauded Merck adenovirus vaccine which may have increased the risk of HIV infection. Fortunately the 2009 Rv144 trial showed a protective HIV vaccine is possible, and subsequent studies showed that certain antibody levels correlated with HIV protection among vaccine recipients. This has fueled a new phase of HIV vaccine research, with many new candidates now in clinical trials built on what we have learned in the past few years.

8. Stagnant funding. For years the United States has been the major funder of the global HIV response. Yet on the heels of the global financial crisis, and a diversification of PEPFAR funds, HIV funding has stagnated and experts fear there is a growing gap between the global HIV need and our ability to address it. Will we look at this year as the beginning of the end of HIV, or the year we started to turn away from the dream of zero HIV?

9. Progress for children. Children are our most precious resource. We have a long way to go, but everybody welcomed the wonderful news from UNICEF that new HIV infections in children have dropped by 40%. Hallelujah! 

10. A PROMISE for pregnant women. There was good news this year for both children and mothers with HIV. This fall, a pivotal clinical trial called PROMISE was closed early when it showed that full antiretroviral therapy is better for new mothers with HIV. It also surprised many of us by showing a dark horse regimen was best. The ethics of the trial were hotly contested, as I wrote recently in Health Affairs, but ultimately the results of the PROMISE study will help drive global HIV policy in the right direction for years to come.

2014 was a great year for HIV. We saw real progress, we made startling new discoveries, and the HIV community remains as vibrant as ever. Would you have chosen the same top 10 trends in HIV for 2014?

Is a clinical trial of therapy for mothers with HIV unethical?

A global health controversy erupted this summer when the prominent scientific journal Nature ran an article entitled “HIV trial attacked.” Within, commentators squared off over whether a huge ongoing study provides suboptimal and thus unethical treatment options to mothers with HIV in the developing world.

How Hospitals Are Getting Safer for American Children

I could tell I was being watched as I walked into the neonatal intensive care unit.

I took off my white coat, folded my stethoscope in a pocket, and hung the coat in a closet. In a nearby sink I washed my hands for a full minute, scrubbing between each finger before drying my hands.

I approached a high-tech isolette and leaned in to examine my patient, the pink baby within.

A voice stopped me: “Doctor!”

There were footsteps behind me. I pulled back and thought, what did I miss? I retraced each step. Coat. Stethoscope. Hands.

The desk clerk pointed a finger. “Your ring, doctor. You forgot to take off your wedding ring.”

She was right. I rolled my eyes, pocketed my ring, washed again, and went back to my little patient.

Small interactions like these make hospitals safer for children by reducing rates of hospital-acquired infections. Now a new article shows exactly how much safer.

Are sugar daddies to blame for HIV in Africa?

Messaging about the prevention of HIV transmission is the ultimate act of cross-cultural communication. In our haste to save lives, it can be easy to make blunders.

Recently, a cross-cultural assumption about African sexual practices that was the focus of prevention messaging has been called into question. That assumption has to do with intergenerational sex, and on closer scrutiny we are reminded about how important it is to be modest in the face of cross-cultural communications.

Is HIV superinfection unhealthy?

People who contract HIV once can contract it again, often through the same risk behaviors that led to the initial infection. A long-standing question has been whether getting infected with a second strain of HIV leads to more rapid HIV disease progression than infection with a single strain.

To this point, a 24-year-old man who has sex with men recently asked me, "Doc, I already rang the bell, why do I care if I get HIV again?"

My answer is at TheBodyPro.

The Paranoid Hypochondriac's Guide to Ebola

The Internet has lit up with news of a burgeoning Ebola virus outbreak in western Africa and the few cases that have trickled through to the United States.

This weekend, TV helicopters beat the air above the ambulance of a US doctor stricken with Ebola and transferred to Emory's high tech containment center for care. Viewers worldwide surely struggled to figure out how this was interesting, and why they were suddenly thinking about OJ Simpson.

Was this the beginning of the end? We'd all seen Gwenyth expire in Contagion so were we next?

Fortunately card-carrying epidemiologists have come to the rescue not with wonder drugs or martial law, but with the facts of the situation: this is a small epidemic largely confined to the developing world and unlikely to be a big deal in the US. It is, however, another reminder that the public health infrastructure in Africa has been neglected. They tried valiantly to placate, to reassure, and to divert the public's fickle attention back to the scarier infectious epidemics that afflict millions every year.

Amid the hubbub, I was proud to be quoted in Erin Gloria Ryan's new Jezebel piece, "The Paranoid Hypochondriac's Guide to the Ebola Outbreak." Should I be worried that the other folks quoted in the article chose to remain anonymous? Heck no! I'm going to go enjoy my ten seconds of fame, knowing full well the firestorm of corrections and trolling will begin soon. Ten. Nine. Eight...

How to Read Education Data without Jumping to Conclusions

Education has entered the era of Big Data. The Internet is teeming with stories touting the latest groundbreaking studies on the science of learning and pedagogy. Education journalists are in a race to report these findings as they search for the magic formula that will save America's schools. But while most of this research is methodologically solid, not all of it is ready for immediate deployment in the classroom.
