A new study from Brazil is reporting significant positive effects of hydroxychloroquine (HCQ) + azithromycin (AZM) on early-stage suspected COVID19 cases. The study was posted as a preliminary manuscript draft on Dropbox a couple of days ago. I just tweeted my thoughts in a long thread, but here is a bit more polished version.
Update 20 April: It was announced today that the study described below has been suspended because of ethical violations. As pointed out by Natalia Pasternak and Carlos Orsi and Ricardo Parolin Schnekenberg (see Additional Reading links below), the study had already started before the ethical approval had been obtained. This could be figured out by looking at the disclosed study days in the preprint and the trial registration at the Clinical Trials website.

The IHU Mediterranee Infection, the Marseille hospital that claims that hydroxychloroquine + azithromycin treatment will cure almost everyone infected with COVID-19 has been reporting very low death rates for COVID-19 patients. As of today, their website reports that the IHU has a much lower death – 1.7% – than the worldwide COVID-19 mortality rate of 6.2%.
While that might look amazing at first glance, these numbers are not surprising, given the high numbers of virus tests that the institute has been performing. Let’s take a closer look at their testing to better understand how the Marseille hospital can get such low mortality rate numbers.

In a new segment on this site, I will start handing out “This Image Is Fine” awards for papers containing images of concern, but where the Editors do not think there is a problem. This first installment of the “This Image Is Fine” award will go to the Journal of the American College of Cardiology (JACC) for deciding that images containing large amounts of duplicated elements are not worth investigating.

The International Society of Antimicrobial Chemotherapy (ISAC) has shared concerns about the Gautret et al. paper published in its own journal. This paper, published under senior authorship of Didier Raoult from the IHU-Méditerranée Infection in Marseille, describes a small study that showed remarkable effects of Hydroxychloroquine and Azithromycin treatment in COVID-19 patients.
After world leaders and politicians started to tweet and endorse this study, many people pressured health officials to start treating COVID-19 patients with this regime, although the study was small and not yet confirmed by independent, larger, and better randomized other studies.
Several scientists and medical professionals, including myself, had concerns about how patients were assigned to each treatment group, how PCR results were reported, why patients with a poor outcome had been left out of the final results, and how this treatment could potentially result in serious side effects. I wrote about my concerns in this blogpost and on PubPeer.
Now, ISAC, who is overseeing the International Journal of Antimicrobial Agents, the journal that published this study, has joined in those concerns.
