Tabulated the topline results released by the #recoverytrial team on #hydroxychloroquine & #dexamethasone, and went over their protocol (recoverytrial.net/results) to better digest them.

Basic stuff:
- hospitalized patients @ 175 NHS centres
- open label, 5 initial arms
- thread—
Important point from #RECOVERYTrial protocol

- if a patient had a #contraindication to one of the intervention arms, according to the clinical care team at the site, that particular arm was not available to that patient at the time of #randomization
So if a patient enrolled in #recoverytrial had a contraindication to #dexamethasone, that patient was not allowed to be randomized to that arm. So the results need to be interpreted in the context of no contraindication to steroids: already on steroids, #immunosuppression, etc.

All right #dermtwitter & #medtwitter, it's time for the...

@MedDermSoc & @DermHospitalist Mini-Symposium on #COVID19 & #dermatology!!

I will be attempting to #livetweet the Zoom meeting!

Join along if you'd like. I will be using the h/t #COVIDDerm!

@RoxanaDaneshjou @dschless
Let's get started!!!!

Your cohosts are super excited to have you join. To give a little background, this meeting was planned in ~1 week, and we have over 500 RSVPs!

@MishaRosenbach now kicking us off with #COVIDDerm! Image
.@DrEstherFreeman is speaking and reminding us all to register our #COVID19 #dermatology cases in the @AADskin #COVID registry!

Reminder to do so here:

1/ Continuing the #immunosuppression #tweetorial series...@MedTweetorials

Today's player: #mTORi, mammalian/mechanistic target of rapamcyin inhibitors

Rapamcyin was @US_FDA approved for #kidneytransplant in 2003.

It was isolated from a soil sample from which island in 1975?
2/ Meet mTOR, a phosphatidylinositol 3-kinase (PI3)-related kinase (adds a phos). mTOR adds a phosphoryl group to serine/threonine residues.

It is a key component of the complexes mTORC1 and mTORC 2 - which regulate processes including cell growth, proliferation, and survival.
3/ mTOR inhibition blocks "Signal 3" of #TCell activation - reducing cytokine dependent cell proliferation and activation.

Take a look at all 3 signals below 👇🏽

1/

Here's another #immunosuppression #tweetorial. This time, a focus on mycophenolic acid (MPA). #MMF #Mycophenolate

The main mechanism of action of MPA is inhibition of which of the following:
2/ Let's meet the players. Mycophenolate mofetil (MMF, left) is a prodrug of MPA while mycophenolate sodium (MPS, right) is an enteric-coated salt of MPA.

MMF administration releases MPA in the stomach, while mycophenolate sodium (MPS) releases it in the small intestine.
3/ MPA is often referred to as an "anti-metabolite", which means a substance that interrupts a metabolic process within cells.

The process that MPA interrupts here: PURINE SYNTHESIS
