Sakatta'iinsi sirnaawaa qorannoowwan namootaa 21, dhukkubsattoota malaria 1,504 hammate hojii dhugaa sadarkaa dhiigaa irratti fi keessumaa sadarkaa gametocyte, kan infekshinii gara bookee daddabarsu, irratti dhiibbaa cimaa qabaachuu isaa agarsiise. Malaria ala, ragaan maxxanfame methylene blue akka antiparasitic bal'aa yookaan akka qulqulleessaa paaraasaayitii mar'imaanii ilaaluuf deeggarsa hin kennu. Argannoon malaria hin taane jechuun ni danda'ama hundi sadarkaa ragaa isa gadi aanaa irratti argama: saanii keessatti hojjeta, yeroo tokko tokko hantuuta keessatti hojjeta, namoota infekshinii qaban keessatti garuu jechuun ni danda'ama matumaa hin qoramne.

Malaria: paaraasaayitii tokko qofa kan qorannoo namootaa qabu

Bara 1891 keessa, Guttmann fi Ehrlich dhukkubsattoota malaria methylene blue'n yaaluu isaanii gabaasan; kunis tarii qoricha sintetikaa jalqabaa dhukkuba namaa irratti fayyadame ture. Seenaan dye irraa gara kompaawundii malaria irratti qoramuutti hanga chloroquine, kan keemistirii jalqaba dye kanaan qorame irraa dhaale, itti fufa.

Hojiin ammayyaa paaraasaayitoonni dandamannaa horatan fedhii uumuun isa deebi'ee kaasa. Culture keessatti, methylene blue Plasmodium falciparum chloroquine irratti miira qabu fi dandamatu concentration nanomolar gadi aanaa irratti ni ittisa; artemisinin derivatives waliin synergy qabaachuun gabaafameera. Namoota keessatti akka monotherapy tti suuta hojjachuu isaa agarsiise: qorannoon to'atame namoota gurguddoo semi-immune Burkina Faso keessatti early failure rate 16 percent argate, barreessitoonnis akka qoricha tokkootti yeroo gabaabaa keessatti fayyadamuuf mijataa miti jechuun murteessan. Walmakaan bu'aa fooyya'aa argate. Qorannoo random ta'e daa'imman 180 keessatti, methylene blue amodiaquine waliin guyyaa 28 irratti corrected response 95 percent gahe; harki methylene-blue lamaanis xiinxala daddarbiinsaa isa waliin gaggeeffame keessatti gametocyte carriage cimsanii hir'isan. Qorannoon triple-combination daa'imman 221 keessatti booda dhiibbaa gametocyte kana microscopy fi molecular detection'n mirkaneesse. Bu'aan hunda caalaa nama ajaa'ibu bookee akka endpoint tti fayyadame: qorannoo phase 2 Mali keessatti, methylene blue guyyoota sadii dabaluun guyyaa lama keessatti mosquito infectivity median 100 percent hir'ise.

Mekaanizimoonni kaadhimamaa sadii irratti mari'atamu; isaan tokko godhanii ilaaluun sirrii miti. Dye'n test tube keessatti enzyme paaraasaayitichaa glutathione reductase ni ittisa (Ki naannoo 6.4 micromolar) akkasumas akka substrate redox-cycle gochuun reducing equivalents ni hir'isa (human fi parasite reductases irratti agarsiifame). Garuu paaraasaayitoonni gene'n enzyme sana hin qabne sensitivity wal fakkaataa qabaatu, kanaaf kun ibsa guutuu ta'uu hin danda'u; yaadni duraanii heme-disposal irratti gufuu uumu jedhu (potency nanomolar waliin walqabate) dhukkubsattoota keessatti ammas hin mirkanoofne. Cuunfaa sirrii: namoota keessatti efficacy dhugaa jira, target tokko kan irratti waliigalame hin jiru, standard regimen keessatti gahee hin qabu. Regimens fi daataan daddarbiinsaa sakatta'iinsa keenya methylene blue malaria irratti keessatti ibsameera; fuulli kun irra deebi'ee hin dhiyeessu.

Babesia fi Toxoplasma: culture keessatti cimaa, kilinika keessatti hin jiru

Babesia, fira malaria kan seelii dhiigaa diimaa keessa jiraatu, akkuma eegametti saanii keessatti concentration submicromolar irratti ajjeefame; paaraasaayitoonni exposure booda deebi'anii guddachuu hin dandeenye (Journal of Protozoology Research) fi screen boodarra gaggeeffame tokko dye kana agent qoraman keessaa isa hunda caalaa potent, naannoo 0.2 micromolar, jechuun sadarkeessise (Carvalho fi colleagues, 2020). Hantuuta keessatti, 50 mg/kg illee inhibition dadhabaa qofa kenne; qorannoon human babesiosis tokko illee hin jiru.

Toxoplasma's fakkii wal fakkaataa qaba. Qorannoowwan culture lama waggoota hedduun wal irraa fagaatan proliferating tachyzoites irratti suppression submicromolar argatan: bara 1989 macrophages keessatti 0.45 micromolar fi bara 2018 screen antimalarial keessatti naannoo 0.30 micromolar. Lamaan isaanii iyyuu latent bradyzoite tissue cyst, sadarkaa kilinikaan rakkisaa ta'e, hin qoranne; qorannoon yaalaa bineensaa yookaan namaa hin argamne. Lakkoofsi tachyzoite saanii keessatti argame infekshinii nama keessa jiru irratti ragaa miti.

Leishmania fi trypanosomes: ifa fi hantuuta irratti xiyyeeffadhu

Barreeffamni Leishmania baay'een isaa dhugumatti photodynamic therapy irratti, yaada dye liqimsuu irraa adda ta'e irratti xiyyeeffata. Photoactivation concentration inhibitory Leishmania amazonensis irratti naannoo 100 irraa gara 20 micromolar tti gadi buuse; ragaan namaa guutuun dhukkubsataa tokko kan madaa isaa antimony argate, tokko immoo dabalataan dye ifaan kakaafame argate qofa. Hojiin hamster irratti topical light-activated treatment gargaare, intradermal dye garuu hin gargaarre (Sbeghen fi colleagues, 2015). Dye naannoo irratti dibamee ifa diimaa gogaa irratti fayyadamuun systemic therapy miti.

Galmeen trypanosome bu'aa negative sakatta'iinsa kana keessatti hunda caalaa faayidaa qabu qaba: methylene blue Trypanosoma brucei in vitro ajjeese, garuu hantuuta infekshinii qaban 300 mg/kg afaaniin yookaan 200 mg/kg injection'n yaaluu hin dandeenye. Dhukkuba Chagas irratti ragaan biochemical dha; enzyme paaraasaayitii-specific trypanothione reductase irratti hundaa'a (Buchholz fi colleagues, 2008), dabalataan in vitro keessatti ifaan cimuun ajjeechaa dabale (Barbosa fi colleagues, 2020). Blood-bank disinfection plasma irratti paaraasaayitii itti dabalame keessatti (Gironés fi colleagues, 2006) waa'ee blood products ti, waa'ee dhukkubsattootaa miti. Namoonni dhukkuba tick-borne irraa gara fuula kana dhufan Lyme disease paaraasaayitii osoo hin taane baakteeriyaal ta'uu isaa hubachuu qabu; ragaan isaa sakatta'iinsa keenya methylene blue Lyme disease irratti keessatti madaalameera.

Raammoo, flukes, fi claim qulqulleessa mar'imaanii

Schistosoma mansoni raammoo keessaa case isa gaarii dha, garuu ammas gahaa miti: dye'n schistosomula 10 micromolar gadi irratti fi adults 10 hanga 30 micromolar irratti ajjeese; hantuutonni infekshinii qaban garuu burden suppression naannoo 60 percent agarsiisan, cure tokko malee. Human pilot xiqqaan paper sana keessatti qoricha walmakaa adda ta'e irratti ture, kanaaf akka human dye trial tti himamuu hin danda'u. Strongyloides larvae fi adults irratti, concentration inhibitory naannoo 4 hanga 6 micromolar penetration dye raammoo keessa seenu waliin walqabate; hantuutonni afaaniin dose argatan garuu to'annoo infekshinii hiika qabu hin agarsiisne. Scabies fi lice irratti ragaan yaalaa namaa tokko illee hin argamne.

Qorannoon ammayyaa, series, yookaan case report amanamaa tokko illee methylene blue afaaniin fudhatamu Giardia, Entamoeba, Strongyloides, yookaan intestinal helminths namoota keessatti dhabamsiisuu isaa hin agarsiisu. Wanti indexed keessaa isa dhihoo ta'e gabaasa bara 1956 gallbladder giardiasis irratti dha; dose argamuu danda'u yookaan cure mirkanaa'aa hin qabu. Paper Giardia ammayyaa lama salphaatti dogoggoraan hubatamuu danda'u: tokko keessatti, 1 percent dye stain trophozoites mul'ise ture; isa biraa keessatti, dilute dye qorichoota standard booda readout stain ture. Stain microscope jalatti paaraasaayitii halluu kennu, qoricha mar'imaan keessatti isa ajjeesu miti. Trichomonas irratti, qorannoon bineensaa tokko qofa jiru ammas photodynamic dha: vaginal dye plus light hantuuta infekshinii qaban keessatti (Fonseca fi colleagues, 2019), oral cleanse miti.
