#Metformin RCT on 41% prevention of #LongCOVID with acute #COVID19 treatment is now published in @TheLancetInfDis at:…

10.4% vs. 6.3% LC incidence.

The distribution of symptoms reported over time was similar as others have found. The figure (a new additional from the original pre-print) displays the freq of symptoms reported over 9 months among those wih a long covid diagnosis vs. no diagnosis. Image
#LongCovid symptoms interfered with both the ability to work and affected leisure activities in about half of those with LC. This very, very slowly decreased over time. Image

Phase-3-Studie: #Metformin führt zu 42% Verringerung der Notaufnahmebesuche/Krankenhausaufenthalte/Todesfälle nach 14 Tagen, zu 58% Verringerung der Krankenhausaufenthalte/Todesfälle nach 28 Tagen und zu 42% Verringerung von #LongCovid nach 10 Monaten.

Eine neue Studie zeigt drei verschiedene Möglichkeiten auf, wie #Metformin gegen #SARSCoV2 wirken könnte

Metformin, ein Antidiabetikum,

➡️ hat entzündungshemmende Wirkungen; es hemmt die Sekretion von IL1b, einem wichtigen Zytokin im "Zytokinsturm" bei COVID-19, und reduziert die Zytokinsekretion

Another confirmatory trial of beneficial effect of #fluvoxamine 100mg BID with Budesonide inhaler in a highly vaccinated population for #COVID19

Dose matters. 50mg 2x/d is not 100mg 2x/d. FLV 50mg 2x/d did not have benefit in two trials
As a combo blinded trial (FLV + inhaler), which one had benefit? Hard to know. In activ-6, we did not observe a benefit of inhaled fluticasone in a double blind RCT, yet UK Principle did see a benefit in open label trial with budesonide.
Importantly the #fluvoxamine dose studied here was 100mg 2x/day.

Covid-out and activ-6 both confirmed a lack of benefit of 50mg 2x/day dose.

If I gave someone 1/2 the effective dose of an HIV med & it didn't work, does that mean the med doesn't work? Or just dose was wrong?

#Paxlovid effect on reducing #COVID19 hospitalizations in vaccinated population finally revealed to the public by FDA. #IDTwitter
0.9% (3/317) paxlovid vs. 2.2% (7/314) placebo…
The relative risk reduction (RRR) of #covid19-related hospitalization was 57.5% (95%CI, -63% to 89%) with #Paxlovid in vaccinated high risk population.

Will point out that the the Hazard Ratio is also 58% for $1 of #metformin.
If one combines the EPIC-SR vaccinated + EPIC-HR seropositive groups together, then risk of #covid19 hospitalization was:
▪️ 0.5% (4/807) with #paxlovid
▪️ 1.9% (15/791) with placebo
Relative RIsk Reduction = 74% (95%CI, 22%-91%)
Number Needed to Treat = 71 (95%CI, 40-300)

Does #metformin reduce hospitalization or not? In a double-blind placebo controlled trial, 28-day data:

NIH guidelines cite the 14-day mITT data where there was not a statistical reduction.
The 14-day and 28-day ITT data also had a statistical reduction in hospitalization.
These numerical complete case data were published in NEJM.
"Through day 28, hospitalization or death occurred in 8 of 596 patients (1.3%) receiving metformin and in 19 of 601 controls (3.2%)"
(2.9% & 1.2% above are by Kaplan-Meier methodology).…
While the authors were not allowed to highlight these data or put a p-value in, apparently there are a lot of poeple who can't run a chi-square or fisher's exact test -- as I keep hearing that metformin didn't reduce hospitalization in the COVID-Out trial.

1/🧵Can a Diabetes drug prevent Long COVID?
Most solid data yet of a medication preventing #LongCOVID from quadruple blinded, non-pharma sponsored COVID-OUT trial N=1,125.

A 42% relative ⬇️ in clinician diagnosed LC was seen (10.6% down to 6.3%).
2/ Metformin’s success (1 LC prevented for every 23 pts treated) could save millions from suffering.

<$1 per course = very cost effective.
Too good to be true?  Maybe but very solid science.

Let me unpack a bit more…
3/ This trial had 6 groups of patients because 3 meds (metformin/fluvoxamine/ivermectin) were randomized vs. placebo.
The other drugs showed no benefit toward Long COVID reduction.
Metformin also looked good for Acute COVID.

Volunteers were followed monthly to 10 mo.
Metformin 42% reduction in Long Covid.…
Incidence of Healthcare provider diagnosed long covid (PASC) was 42% less among those randomized to #metformin vs. matched placebo.

Hazard Ratio for Long Covid in the metformin group versus control was 0.58 (95% CI 0.38 to 0.88, P=0.009); Image
There was no benefit for those randomized to #ivermectin vs. matched placebo for reducing long covid and low-dose #fluvoxamine was not beneficial either for decreasing #longcovid. ImageImage

Here is a thread explaining the main results-

#aging #longevity 1/12
Life expectancy has increased dramatically over last 150 years - most US children born today are expected to live into their mid-80s #longevity. This has shifted the disease burden towards chronic Non-Communicable diseases #aging and an increase in years spent in poor health 2/12 ImageImage
How should we value these past and future life expectancy gains? Is a compression of morbidity more valuable? What is the value of treatments that delay #aging? How does that compare with treating single diseases? 3/12

1/12 👩🏼‍🔬 Nieuw onderzoek (preprint): "#Metformin use is associated with reduced mortality in a diverse population with COVID-19 and diabetes"

Is dit dan 'n middel tegen COVID-19? Het mag goed klinken maar ik denk 't niet 👇🏻

(CW ziekteangst, ongelijkheid)…
2/12 Achtergrond: type 2 diabetes mellitus (T2DM) is een vorm van suikerziekte waarbij het lichaam niet meer goed op insuline reageert (insulineresistentie).

Dit in tegenstelling tot type 1 (T1DM) waarbij het lichaam wel goed op insuline reageert maar het niet meer zelf maakt.
3/12 Om schadelijke gevolgen van een hoge bloedsuikerspiegel bij T2DM te voorkomen krijgen mensen medicatie om deze te verlagen. Metformine wordt veel gebruikt.

Het is een bijzonder middel: we weten niet zo heel goed hoe 't werkt.

Daarover later meer; eerst naar 't onderzoek.

(1/) An update of analysis of Dr. Raoult’s #hydroxychloroquine #azithromycin trial on 1061 patients.
(warning: it’ more like conspiracy theory)
(2/) Actually the preprints have two versions.

“Version 2”…

Final version…

There're minor changes in the final version compared to v2. Most are Ct values and HCQ serum concentrations. Other baseline characteristics are the same.
(3/) Another difference is the way that NEWS scores were presented.

Version 2. Mean-Sd-median-range.

Final version. Low-medium-high brackets.

Insulin is NOT a first choice medicine in type 2 diabetes mellitus (T2DM).

- Short-term use in #T2DM:
(1) ketosis
(2) sepsis
(3) extremely high blood glucose
- Long-term use in #T2DM:
(4) secondary oral medication failure (also called ß-cell failure)

The guideline chart attached above is very clear - lifestyle modifications should be the first choice ± #metformin. Metformin is cheap.
I am least influenced by industry, and use long-term insulin in <5% T2DM, mostly for reason (4), usually after exhausting other options.

Those <5% are at a secondary level care hospital, and not at primary care. In primary care, that number will be even lower.

For those who NEED, both biphasic insulin and glargine are available in @pmbjpbppi #JanAushadhi kendras too. Insulin is quite inexpensive there.
