Early Treatment of COVID-19 Patients With HCQ+AZ Shows Benefit, Study Finds (sciencedirect.com) 284

"Over at ScienceDirect, they report on a French 'retrospective' study of just over 1,000 patients across all age groups with very good results," writes long-time Slashdot reader kenh. The analysis found that administration of Hydroxychloroquine (HCQ) and Azithromycin (AZ) before COVID-19 complications occur "is safe and associated with very low fatality rate in patients." From the report: Background: In France, the combination hydroxychloroquine (HCQ) and azithromycin (AZ) is used in the treatment of COVID-19.

Methods: We retrospectively report on 1061 SARS-CoV-2 positive tested patients treated with HCQ (200 mg three times daily for ten days) + AZ (500 mg on day 1 followed by 250 mg daily for the next four days) for at least three days. Outcomes were death, clinical worsening (transfer to ICU, and more than 10 day hospitalization) and viral shedding persistence (more than 10 days).

Results: A total of 1061 patients were included in this analysis (46.4% male, mean age 43.6 years -- range 14-95 years). Good clinical outcome and virological cure were obtained in 973 patients within 10 days (91.7%). Prolonged viral carriage was observed in 47 patients (4.4%) and was associated to a higher viral load at diagnosis (pA poor clinical outcome (PClinO) was observed for 46 patients (4.3%) and 8 died (0.75%) (74-95 years old). All deaths resulted from respiratory failure and not from cardiac toxicity. Five patients are still hospitalized (98.7% of patients cured so far). PClinO was associated with older age (OR 1.11), severity at admission (OR 10.05) and low HCQ serum concentration. PClinO was independently associated with the use of selective beta-blocking agents and angiotensin II receptor blockers (p less than .05). A total of 2.3% of patients reported mild adverse events (gastrointestinal or skin symptoms, headache, insomnia and transient blurred vision).
On the contrary, a separate study, which has not been peer-reviewed, found the two primary outcomes for COVID-19 patients treated with hydroxychloroquine were death and the need for mechanical ventilation.

"The study analyzed only 368 patients but represented the largest look at the outcomes of COVID-19 patients treated with hydroxychloroquine -- with or without azithromycin, a common antibiotic -- anywhere in the world," The Hill reported more than two weeks ago.

UPDATE (5/9/2020): A new hydroxychloroquine study -- "the largest to date" -- was published Thursday in the prestigious New England Journal of Medicine. It concluded that Covid-19 patients taking the drug don't do any better than those not receiving the drug.

    Keep in mind that this was a retrospective, not a controlled experimental study. By nature that makes it less easy to reliably interpret. But this is the largest study of HCQ+AZ yet, and so should certainly get some attention.

      Yeah, testing it on Veterans' Dept. guinea pigs doesn't count, eh?

      • There was no test on veterans.

        It was just individual doctors grasping at straws, the problem with that of course is that the HC would on average have been administered for the most desperate cases with dosage entirely up to their discretion. So those cases dying more is not surprising.

        Less dying for the French study at the same time is very surprising. One major difference between the US veteran's and the French patients is that the French at least had a treatment protocol.

    I've been working in drug discovery for over 40 years so I have a little insight into this. There is so much bullshit being posted by morons on HCQ and this and that trial. This is not the place to post yet another half-ass study. Stick to computers and stuff. You're not helping anything here.

      We both know this is about more page views (and ads) for Slashdot.

      There never should have been a presidential announcement that is was a “cure;” as a result, it’s become highly political, and great fodder to drive slashdot comments.

      Besides... it looks like the number of people who recover doesn’t appear statistically different from nothing at all. So yeah... I’ll leave the researchers to do their thing. Nothing truly interesting here.

        There wasn't. The president announced that there was promising evidence for some treatments.

        The media made it up "cure" out of whole cloth.

          HYDROXYCHLOROQUINE & AZITHROMYCIN, taken together, have a real chance to be one of the biggest game changers in the history of medicine. The FDA has moved mountains - Thank You! Hopefully they will BOTH (H works better with A, International Journal of Antimicrobial Agents)..... ....be put in use IMMEDIATELY. PEOPLE ARE DYING, MOVE FAST, and GOD BLESS EVERYONE!

          • No mention of a cure there.

            How did you want this to work? Did you want me to read into his words that which YOU think he MEANT to say? (or more likely, what you really wished he had said, so that you could quote him saying it? but since he didnt...)
          • Is this research in France being done by a company which sells the name brand version of hydroxychloroquine?

            You know, the same company Trump has an investment in?

          There wasn't. The president announced that there was promising evidence for some treatments.

          Which was still not true. Anybody who read about the history of chloroquine trials on SARS would not have considered an in vitro study to be promising, and would have dismissed the early French study outright.

Let the professional medical personnel you have employed talk about the medical stuff.

    • Everyone wants to draw a conclusion with every press release like this. People find it difficult to just say, "oh, well there's some more data we might be able to use at some point, I'll continue and wait to see what the experts conclude." It guess it make sense that people want to draw a conclusion one way or another, or show extreme optimism or skepticism. But really, anyone with a basic education should know better.

Too many "experts" have recommended horrendous "solutions", and we blindly go along with it because, afterall, they're "experts". Nevermind you can find an "expert" to agree with whatever position you want.

            That is a nice and complete fail in recognizing reality and your own limits. If you think you can, for example, replace a researcher in epidemiology even only somewhat competently, then you are completely deluded. Get that MA infectious diseases or medical statistics or the like and then do a real PhD in epidemiology and you will _begin_ to understand things. Add a decade or two of on-target experience and you start to become an actual expert. Even if you just want to follow the field competently, you will

      • by gweihir ( 88907 )

        Nope. What you need to learn is recognizing experts. You _cannot_ competently replace a real expert. (Of course, there are a lot of fake experts around, starting on the low end of actual insight with a well known "stable genius" and going up to actual professors that are not in the right specialty and vastly overestimate their specific level of insight into something they have limited experience with.) This is not a case where thinking for yourself on the subject matter itself is going to make things better

    • by methano ( 519830 )
      OK, I'll try again. There's a blog called "In the Pipeline" (google it) that's pretty well respected in the drug discovery world of medicinal chemists. The blogger has been doing a pretty good job explaining the science around finding treatments for COVID-19. He's covered a lot of these trials including the French study that started it all. Quit bashing me and go read a little. It isn't just about DT.
    • by gweihir ( 88907 )

      Indeed. Too many technical people (and too many people in general) have no clue where the limits of their insights are. It is not an accident that double-blind is the gold standard. It comes from even seasoned professionals in the right area have trouble coming up with reliable info unless the experiments are done very, very carefully. Interpretation of messy data by non-experts is a complete fail and can only make things worse.

  • That's not a study, that's an abstract. Answer this: what was the age of the participants? What were their conditions?

    Every negative study I've seen with HC has been with advanced stage C19, or with advanced aged participants, usually both. Everything else I've seen suggests HC ( and HC+AZ ) given early on ( onset of symptoms ) has a tremendously positive impact on outcomes.

    I'm open to new data, of course; so lay it on me.

  • I remember when Pons and Fleishmanm "discovered" cold fusion. After it was debunked in the physics community, one of the smartest physicists I knew said this to me: "To bad it was being picked up by 'conspiracy theorists', anything there will be hidden by the noise generated for the next tw3enty years.

    There was something there, just look at Stephen Jones and at muon-catalyzed fusion. The professor was wrong, it is going to be at least forty years.

    We already know the vast, vast majority of people recover from Covid-19 on their own or with oxygen.

    How does a retrospective study work? What is the "control" population? They studied 1000 patients that took the drug, but how do they compare these outcomes with patients that did not take the drug to know if it was effective? How do they choose the patients to study and avoid choosing a sample set of patients that would have recovered anyway?

      You can use the general admissions in the country not subjected to this treatment regimen as the control group.

      The mortality rate in France is 4% (that is based on national statistics). He has achieved mortality of 0.75% with a reasonably good sample size this time.

      So unless he has cherry picked patients and has turned the ones who are likely to die and spoil his statistics at the door, he is onto something. That is a pity, because he is a d*ckhead and j*rk of the highest order, but sometimes even d*ckh

  • I am having trouble understanding the conclusions of this study. The statement in the conclusion (and, yes, I RTFA'd) says that it was safe. It did not seem to indicate at all that it was an effective treatment. Is that the message that I am supposed to draw from this? If not, what am I missing?

    • You're not missing anything. There wasn't any control in this study, so there's no comparison between the outcomes they saw and what the outcomes would've looked like with standard treatment without the extra drugs. Which means they can't even conclude the combination is safe because without that control there's no way to tell if it was better than, worse than or the same as standard treatment. The best the study shows is that it's probably not egregiously more dangerous than normal treatment, but that's ab

    I am french, and I am a scientist. I have been interested in the so-called "results" obtained by french medical team in Marseille before they became so famous. While I was overwhelmed at first, I am sorry to say that the studies they produce are mostly bs: they are useless from a scientifical point of view, and even damageable on a social and medical point of view. They mostly prove nothing, and take advantage of presenting themselves independant from Bigpharma, while there not, to gain fame. It's really embarassing for french research and government, so much it's hard for them to go againt this Pr Raoult who's become some kind of a local savior and guru. The most comprehensive study you could find could be this one: https://translate.google.com/t...
