    An SSRI to treat early COVID, supposedly SSRIs can inhibit SARS-CoV-2 and also potentially have anti-inflammatory and immunoregulatory properties. I think also earlier this year there was an observational study showing patients taking SSRIs had lower risk of severe COVID and death (I think a medXriv paper)

    Is this just a glorified let’s throw an SSRI at it to see if it sticks. Will it be tryclics next. Is there genuinely any science behind this.

    The JAMA work was a small but gold standard RCT and it showed efficacy. So similar cohort size to RituxME trial and if that trial showed efficacy would we care if we knew any science behind it?

    How does the dosage compare to doses for depressive conditions?

    ETA ages ?
    Were any side effects observed at particular points in menstrual cycles?
    Did any participants gave gut issues ?

    Estrogen and seratonin are closely linked, and some gut bacteria can " repackage" compounds including estrogen / influence seratonin levels.

    Needs a bit more digging to understand mechanisms

    Looks like much more of a rationale - or at least no less - than say the rituximab and cyclophosphamide trials for ME.

    Aka Luvox,they titrate up to max dose then discontinue
    I found Luvox the easiest to tolerate and discontinue from

    I’m confused, has this been refuted by the scientific community as one of the causes of COVID worsening?

    Yes. (and from what we knew about SARS-1, it was not a likely hypothesis)

    "Is a “cytokine storm” relevant to COVID-19?" June 30, 2020
    https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2767939
    (tl;dr: no)

    "Cytokine Levels in Critically Ill Patients With COVID-19 and Other Conditions" September 3, 2020
    https://jamanetwork.com/journals/jama/article-abstract/2770484
    "The findings of this preliminary analysis suggest COVID-19 may not be characterized by cytokine storm."

    "Cytokine elevation in severe and critical COVID-19: a rapid systematic review, meta-analysis, and comparison with other inflammatory syndromes" Octover 16, 2020
    https://www.sciencedirect.com/science/article/pii/S2213260020304045
    Evidence shows that like SARS-1 and some other coronaviruses, COVID19 is actually associated with an impaired cytokine response (of interferons).
    https://www.sciencedirect.com/science/article/pii/S2211124720312237

    Lastly, cytokine inhibitors (such as Tocilizumab, a IL-6 inhibitor) have failed to demonstrate efficacy in COVID19

    https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2772187
    https://www.nejm.org/doi/full/10.1056/NEJMoa2028836


    Now, all of this is not to say that there are zero cases of cytokine release syndrome associated with COVID19, indeed with over fifty million confirmed SARS-CoV-2 cases, cases of rare syndromes like this will show up. Note that most cytokine release syndrome cases are associated with immunotherapies, such as those that use (engineered) chimeric antigen receptor T-cells as an anti-cancer therapy.

    This ties in with results from Synairgen, who developed Interferon-1B as a treatment for severe asthma and have done trials on its effect on Covid19.
    https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30511-7/fulltext

    Sir Stephen Holgate and others at Southapton have developed this.
