Study of 96,000 Covid-19 Patients Finds Hydroxychloroquine Increased Their Risk of Dying (bbc.com) 264

"The drug US President Donald Trump said he was taking to ward off Covid-19 actually increases the risk of patients with the disease dying from it," reports the BBC, citing a new study published Friday in the Lancet.

"The study said there were no benefits to treating patients with the anti-malarial drug hydroxychloroquine..." Hydroxychloroquine is safe for malaria, and conditions like lupus or arthritis, but no clinical trials have recommended the use of hydroxychloroquine for coronavirus. The Lancet study involved 96,000 coronavirus patients, nearly 15,000 of whom were given hydroxychloroquine — or a related form chloroquine — either alone or with an antibiotic.

The study found that the patients were more likely to die in hospital and develop heart rhythm complications than other Covid patients in a comparison group. The death rates of the treated groups were: hydroxychloroquine 18%; chloroquine 16.4%; control group 9%. Those treated with hydroxychloroquine or chloroquine in combination with antibiotics had an even higher death rate.

The researchers warned that hydroxychloroquine should not be used outside of clinical trials.

The BBC also reports that a separate trial involving over 40,000 healthcare workers around the world is now testing whether hydroxychloroquine could prevent infection.

UPDATE (6/4/2020): The study's three authors retracted their study on June 4th, "because independent peer reviewers could not access the data used for the analysis," reports The Hill. "The source of the data was Surgisphere Corporation, which told peer reviewers it would not transfer the full dataset used for the study because it would violate client agreements and confidentiality requirements."

However, the same day the New England Journal of Medicine published results from a new double-blind randomized, placebo-controlled trial which found hydroxychloroquine didn't help prevent people exposed to others with Covid-19 from developing the disease. One of the study's co-authors said that as a preventative agent, "It doesn't seem to work."

    This is a retrospective study. Until we get good double blind randomized results, we cannot read into this very much. For example, it is possible that doctors have been prescribing hydroxychloroquine to the patients who were most sick. (One could actually have a complication in the other direction if the drug is limited and so doctors don't prescribe it to the patients they are sure are going to die). We need to wait for randomized trials which will be done in the next month or so before making any strong conclusions.

    The last time there was a retrospective study mentioned here which suggested that hydroxychloroquine worked, I posted almost the exact same comment and got accused of it being an anti-Trump thing. One of the most concerning is to see actual scientific questions become partisan political footballs almost in real time. Right--leaning internet fora seem to crow about every retrospective study showing positive signs for hydroxychloroquine treatment ,and left-leaning fora seem to crow about every negative one. And in both cases, any response to pointing out that such studies are of limited value due to their retrospective nature and to wait for the blinded, randomized trials before making major conclusions is met with disdain and an assumption that one must be a political footsoldier for the hated other side.

      While an RCT is the gold standard, the Lancet study did control for baseline disease severity, as well as a wide array of confounding factors: BMI, age, preexisting conditions. It also excluded patients who were sick enough at the time of prescription to be put on ventilators, or where the prescription followed the initial diagnosis by more than 48 hours.

      This is far more rigorous than any of the early papers reporting near-miraculous results. It is about as good as evidence as we're likely to get any time soon for people sick enough to be hospitalized.

      There is an RCT going on now for people who have been diagonsed with COVID-19 but are not sick enough to be hospitalized, looking to see if chloroqine reduces the duration and severity of the disease.

      Another study shows that Hydroxychloroquine, when used with AZ (antibiotic?) is effective and I have heard many sources (MDs) say that adding zinc to the mix is even more effective.

    This is a disinformation piece, again.

    What is well known at this point is that the Zinc ion is what is responsible for helping the immune system fight off SARS-CoV-2, as a prophylactic anti-viral, in the HCQ+Zn combination drug. The ionophore HCQ helps get the Zinc ion into cells and into the endosomes where it can be useful.

    HCQ without Zinc is not the prescription - that is silly.
    HCQ used to treat an advanced infection is not a prescription - that is silly.

    This was all established with SARS-1 - it's not new. Go fact-check on pubmed.

    Confirming the SARS-1 results is OK for confirmation science, but these HCQ-only studies do not conclude that HCQ+Zinc is ineffective as a prophylaxis. All the studies coming back on HCQ+Zn are showing moderately beneficial effects, decreased deaths, and greatly decreased morbidities.

    It's easy to confirm that the POTUS's physician, tautologically among the best clinicians, prescribed him HCQ+Zn. But OrAnGe MaN BaD media wants to politicize science at the cost of human lives. That's actually BaD.

    Meanwhile the WHO says that among 300 *million* HCQ doses, no unexplained deaths have occurred. At least they did their gigantic 2016 study, before politicians decided to fight on medicine's turf.

    This study focused on those who were already ill, and says nothing about any possible preventative aspects of being treated BEFORE becoming ill.

    Many drugs are good for one, or the other, but rarely both.

    The hard part of the problem is it is much harder to evaluate preventative use (also known as prophylactic use), as the statistics alone require test populations that are at least an order of magnitude larger than for curative or palliative (comfort) drug evaluation.

    Hydroxychloroquine is fortunate in this respect, as it was already in active use prior to COVID-19. First, a study is needed to see the COVID-19 infection rates and disease development in the pre-existing population of hydroxychloroquine users.

    In parallel, a study is ALSO needed that will give hydroxychloroquine to a large healthy population. For which it seems our dear President has already volunteered!

I mean it's common knowledge that preventative medicines and treatments require two completely different mechanisms, so I only assume you think HCQ is some kind of magic do everything drug?

      Does it replace the blue pills too? Can it make me harder than algebra?

  • Hey Donny. If you double the dose it will work twice as well
  • "The drug US President Donald Trump said he was taking to ward off Covid-19 actually increases the risk of patients with the disease dying from it," reports the BBC, citing a new study published Friday in the Lancet.

    So President Trump is taking HCQ to prevent infection, Trump is not infected/being treated for Covid-19

    "The study said there were no benefits to treating patients with the anti-malarial drug hydroxychloroquine..."

    Presumably patients WITH Covid-19, unlike the President who does not have Covid-19.

    The BBC also reports that a separate trial involving over 40,000 healthcare workershydroxychloroquine could prevent infection.

    I take it HCQ is not likely to kill the 40,000 healthcare professionals that are NOT INFECTED with Covid-19 - why do people keep conflating prophylactic use with treatment? The President touts prophylactic use, the press pushes back with studies of post-infection treatment. (Reminds me of an old beer commercial - "Tastes g [youtu.be]

      The last quote line was butchered, it should have read:

      The BBC also reports that a separate trial involving over 40,000 healthcare workers around the world is now testing whether hydroxychloroquine could prevent infection.

    • Now, now, don't confuse people with facts they don't want to hear. Even if it doesn't prevent Covid, it will at least keep the prez from getting malaria when out and about on his golf course, so taking it isn't completely useless.

      We don't know if it is likely to be a benefit: "We still do not know whether anything is beneficial in COVID-19,” the University of Oxford’s Professor Nicholas White, the study’s co-principal investigator, told Reuters." https://www.reuters.com/articl... [reuters.com]

      Trump (and various Fox News personalities ) touted HCQ as a treatment, now they are touting it as a prophylactic. But it is worth noting that Trump now says that he is quitting HCQ because "I think the regimen finishes in a day or two

  • "The Lancet study involved 96,000 coronavirus patients, nearly 15,000 of whom were given hydroxychloroquine — or a related form chloroquine — either alone or with an antibiotic."

    In other words they only used one third of the treatment that has been cheaply working, if they just didn't give them a 'different' type of chloroquine all together.
    Not to mention straight chloroquine is less safe than hydroxychloroquine.

  • Hydroxychloroquine gained attention because patients in Chinese hospitals who happened to be taking it for other conditions did not seem to be catching COVID-19. It doesn't follow that it would help if you already have severe symptoms. Also, anyone looking to visit Africa for fun has to take the stuff for a months before and throughout as prophylactic. So if you want to try it off label, you are not taking any more risk than if you want to see some hypos. Probably doesn't work, because few things do till pr

No spitting on the Bus! Thank you, The Mgt.
