Among these, Chloroquine or derivatives therefrom. I wondered whether oral thalidomide might not be of good use in this respect. This drug was used initially for a similar purpose with great success, by Convit , Soto and Sheskin to allay reactional phenomena in reactional lepromatous leprosy(1). We (Goihman-Yahr, Requena, Vallecalle-Suegart and Convit) used thalidomide in experimental autoimmune diseases of the rat (2). We found that the drug administered intragastrically in rats was effective in preventing and treating "distant lesions" of adjuvant disease. Namely, arthritis, vasculitis of the skin and iridocyclitis; as well as loss of weight and wasting. It was NOT effective in treating or preventing experimental allergic encephalomyelitis or experimental allergic neuritis. We (Goihman-Yahr, Rodriguez-Ochoa, Aranzazu and Convit) also found that peripheral blood neutrophils were activated in reactional lepromatous leprosy, but not in other forms of leprosy. This was not due to anergy of neutrophils in non reactional leprosy (3). I have NO direct experience, nor a feasible way to personally test thalidomide in the serious late phase of COVID 19; but suggest that its use should be considered (in patients that are not women of child-bearing age) to prevent or treat patients with this condition. The possible side effects of thalidomide are detailedly covered in Martindale“s, "The Complete Drug Reference" (4) but most of them occur in patients with complex pathologies including malignant neoplasia. In my long term clinical experience with the drug, the only frequent side effect besides sleepiness, is alteration in peripheral nerve conduction with prolonged administration.
