L’HYDROXYCHLOROQUINE EST ELLE EFFICACE? Nous avons enfin la reponse

Ces derniers jours les études sur le protocole Raoult et l’Hydroxychloroquine, se sont multipliées. Monique Plaza communique les liens de toutes les études publiées, positives et négatives . .Il faut bien lire très bien lire car il n’existe pas de médicament miracle , pas même le Remdevisir promu par le gouvernement?

On s’amusera à parcourir la belle étude à laquelle participa le professeur Caumes, ennemi déclaré de Raoult, les résultats bruts sont très favorables à l’hcq alors il a fallu les tordre en intégrant un trop bon état général des malades ayant bénéficié de ce traitement.. Etrange; les diabetiques et les obèses étaient plus nombreux parmi ces malades…

On notera que sur les 60 études , en dehors de Marseille les européens ont refusé d’étudier l’efficacité du traitement précoce.

Quels sont les résultats de ces études?

L’hydroxychloroquine est efficace à titre préventif et dèsles premiers symptômes et permet donc de limiter la charge virale. C’est la thèse de Raoult qui est confirmée.

La bonne surprise provient d’une certaine efficacité pour les formes graves .

Pour un traitement précoce à l’hydroxychloroquine: 13 etudes positives 0 négatives

Traitement prophylactique préventif à l’hydroxychloroquine 10 positives 0 négative

traitement tardif à l’hydroxychloroquine 14 positive 10 non efficace

Autres études 13 efficaces et 0 inefficace

Mieux que les études il y a les taux de mortalité: heureux les pauvres qui ont du se soigner avec le très peu couteux protocole Raoult Dans ces payx après avoir réajusté l’âge pour ne pas fausser les résultats, le taux de mortalité y est six fois moins élevé que chez nous .

    Si à l’étranger, les pays ont recours à l’hdroxycloroquine,en Europe, ce sont quasiment les plus touchés qui l’ont interdit.

    Mais cette sortie du déconfinement (bien que les médias reprennent de plus en plus le slogan d’un possible second à la Rentrée, en s’activant dur pour cela) n’est pas encore une victoire.

    Même pour l’enquête parlementaire en cours, J’ai entendu ce matin sur RTL que Martin Hirsch réclamait d’être entendu par l’Assemblée pour contredire la déclaration du Professeur Raoult. Les beaux jours sont là, mais il ne faut surtout pas baisser les bras, car en face, ils s’activent.

    Continuons à défendre le professeur Raoult et les interventions de personnes de c du professeur Peronne, si une vingtaine de ce rang faisait bloc, on commencerait à faire changer les choses. Alors, il faut aller les convaincre, l’un après l’autre.

    Cher Monsieur, bien sûr que l’on va continuer à faire confiance à Didier Raoult et le soutenir à notre petit niveau. Pensez-vous que c’est par hasard que, ce soir 2 juillet 2020, l’on rediffuse sur la 5 un reportage au sujet des recherches spatiales et de la future adaptation des humains sur d’autres planètes ?? Lorsque j’avais environ 15 ans, cours de Verdun à Lyon, il y avait ce que l’on nomme la « Vogue », un manège nommé « La Centrifugeuse », on entrait dedans et lorsque ça tournait, en rond bien sûr, nous étions plaqués contre la parroie. Ce manège a été interdit. L’Eeffet accentué de la gravitation rendait les gens un peu malades. En matière de recherche Spatiale, ils reproduisent la même chose pour que le corps humain sache s’adapter aux turpitudes existentielles de la planète Terre. C’était scientifique avant l’heure !! Pourquoi, après tant d’années, on vante des expériences déjà acquises. Pourquoi donc, sachant qu’il y a des centaines de milliards d’années, l’origine de l’homme émane de bactéries (je ne sais pas expliquer, car je ne suis qu’un petite femme lambda, mais passionnée par ce qui se dessine à « petits pas » pour notre Planète. Demain, j’ai 77 ans et je vois venir les choses…
    Je pense que notre cher Pr Didier Raoult, est à l’opposé de tous ces scientifiques, parce que lui vraiment il sauve des vies et en sauvera encore ! Pardonnez mon vocabulaire qui n’a rien de scientifique, mais je comprends à un autre niveau, ce qui se passe. Que la vraie Lumière éclabousse et rende la vie de nos descendants plus joyeuse !…

    décidément on aura beau faire comprendre à quelques bornés que le protocole du professeur raoult éffectué avec sérieux donne des résultats mais rien n’y fait faut absolument donner des gages au milliardaire bill gates qui finance l’oms et veut etre sur le podium pour la découverte d’un vaccin dédié au plus offrant comment peut on etre sourd à ce point?bien sur comme tout etre humain le professeur raoult a ses défauts mais il soigne et il faut le reconnaitre avec succès alors continuons à soutenir le professeur raoult et le professeur peronne qui sont à l’opposé de certains scientifiques qui ne pensent qu’à leur nombril et leur carrière décidément on a aussi un ministère de la santé qui est aussi sourd que ceux cités plus haut
