    Chloroquine kills sporozoites


    Lets see what the news say and if it’s real or fake news just for scams. The antimalarial drug chloroquine phosphate can’t kill coronavirus directly. It is however being claimed that it can help the body in getting rid of the virus in initial stage.

    The late 1970s–early 1980s using infection under chloroquine CQ prophylaxis 14–16. The rationale is that administration of antimalarials with sporozoites allows parasite infection of the liver but prevents the erythrocytic phase where clinical disease occurs. In the case of CPS with CQ, which selectively kills asex-ual Chloroquine kills blood stage parasites as they reach the trophozoite stage of development Yayon et al. 1983, but the effect of CQ on LS parasites has received less attention. It is widely believed that CQ does not affect LS development, allowing the immune system to encounter the full repertoire of LS antigens. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen.

    So as lysosomes inside the white blood cells can get rid of harmful foreign viruses and bacterias entering into the body, thus having more acidity means more ability to disrupt the virus and kill it (or denature it). It’s being claimed that chloroquine increases the acidic properties of the lysosomes inside the cell.

    Chloroquine is the drug of choice for treating most patients with malaria caused by P. vivax, P. ovale, P. malariae and chloroquine-sensitive strains of P. falciparum. However, due to the development of resistance, chloroquine is ineffective against most strains of P. falciparum in South America, Africa and Asia. Volunteers immunized under chloroquine chemoprophylaxis with Plasmodium falciparum sporozoites CPS develop complete, long-lasting protection against homologous sporozoite challenge. Chloroquine affects neither sporozoites nor liver-stages, but kills only asexual forms in erythrocytes once released from the liver into the circulation. Pre-incubation of sporozoites in a thiostrepton solution. We incubated batches of mature sporozoites in each of the following, thiostrepton 500 mg ml −1, primaquine 50 mg ml −1 or chloroquine 50 mg ml −1. Primaquine kills sporozoites and therefore was included as a control for drug activity.

Patients in whom chloroquine or hydroxychloroquine have failed to prevent or cure clinical malaria or parasitemia, or patients who acquired malaria in a geographic area where chloroquine resistance is known to occur should be treated with another form of antimalarial therapy see INDICATIONS AND USAGE - Malaria and WARNINGS.
