Bon... alors que je suis actuellement en 🇨🇫, l'un des pays endémiques pour le #monkeypox, voilà qu'une épidémie internationale inédite prend une ampleur très inquiétante...
Quelques considérations sous forme de 🧵... L'Institut Pasteur en 🇨🇫 @I_P_Bangui est l'une des institutions qui a le plus d'expérience dans la surveillance & la prise en charge du monkeypox.
L'antiviral recommandé pour monkeypox, le tecovirimat, y fait l'objet d'un programme d'accès compassionnel pasteur-bangui.org/6-decembre-202…

While the decision of the 🇺🇸 governement to support an IP #waiver on #COVID_19 vaccines is a step in the right direction, many other things now need to happen. 🧵1/9 For the waiver to effectively accelerate vaccine availability, significant 💰 investments are needed, as well as "tech transfers". 2/9

🔥EXCELLENT results for Phase III multicentric double-blind RCT of #proxalutamide for hospitalized #COVID_19 patients🔥
n=588
Study led by @FlavioCadegiani in 🇧🇷
92% reduction in mortality ! prnewswire.com/news-releases/… 2/
Keep in mind that this is a press release, not a scientific publication.
A point is particularly unclear in the press release, i.e. authors claim 588 patients were enrolled, but then later write they were 294 in proxalutamide group & 296 in control group.
294+296=590≠588.

Excellent results for phase 3 placebo-controlled RCT in 🇺🇸 among mild-to-moderate #COVID_19 patients at high risk of clinical deterioration.
Cocktail of 700mg of #bamlanivimab & 1,400mg of #etesevimab reduced risk of hospitalizations & death by 87%. 2/
This press release needs to be taken with grain of salt. Among other limitations, it says nothing about different variants of concern.

Large RCT (n=930) in Barcelona, 🇪🇸: #calcifediol vs control among hospitalized #COVID_19 patients.
Strong clinical benefit: ↘️ICU admission & ↘️mortality.
Unclear to me why this preprint got unnoticed (published three weeks ago) !

These new results confirm similar positive results for calcifediol generated in Cordoba in a smaller pilot RCT

Quelques éléments de contexte pour expliquer le communiqué de presse de @Merck qui conclut à l'absence quasi totale de preuves en faveur de l'#ivermectine (IVM) pour #COVID_19 🧵merck.com/news/merck-sta… Petit disclaimer pour commencer : je ne suis ni "pro-IVM", ni "anti-IVM". Ces catégories n'existent que dans les esprits des gens qui politisent tout et n'importe quoi.

Bangladesh: large RCT (n=606) of #mouthwash, gargling, nasal spraying & eye drops w/ 1% povidone-iodine (PVP-I, aka #Betadine) for #COVID_19. Every 4 hours for 4 weeks.
Impressive results.

h/t @Covid19Crusher Mouthwash solutions of PVP-I can be easily purchased OTC in many countries. Nasal sprays and eye drops are less easily accessible (i.e. not available OTC in France).

There have been several small RCTs over the last weeks suggesting a clinical benefit for #ivermectin for #COVID_19.

It’s time for a MEGA THREAD on ivermectin, aka the “wonder drug”!

Let's start the show !🔥🔥🔥 2/
Ivermectin belongs to the family of avermectins, which are natural fermentation products of soil bacteria. A Nobel Prize of Medicine was awarded for their discovery. Image

In this thread, I’ll speak about #tocilizumab and challenges to access it. Tocilizumab is an anti-IL-6-receptor monoclonal antibody. It is a promising investigational drug to treat the cytokine storm associated with severe #COVID19. 2/
The cytokine storm (aka cytokine release syndrome) occurs when a high number of white blood cells are activated and release inflammatory cytokines, such as IL-6, which in turn activate more white blood cells.

In this thread, I’ll share what is known about access to #remdesivir, one of the leading therapeutic candidates against #COVID19. Originator company @GileadSciences ($GILD). As an introduction, I suggest you should read this very detailed article. biopharmadive.com/news/coronavir… 1/n Remdesivir (aka GS-5734) inhibits RNA-dependent RNA polymerase. Broad-spectrum antiviral. Injectable (IV). Wasn’t found as clinically effective for #Ebola as monoclonal antibodies. Here is the formula. The synthesis of GS-5734 is described here. pubs.acs.org/doi/full/10.10… 2/n
