Methylene blue n'indwara z'ububyimbirwe bw'amara: ubushakashatsi ugereranyije no gusiga irangi mu isuzuma

Uburyo bubiri bukoresha molekile imwe y'ubururu, ariko nta bindi byinshi buhuriraho. Mu buryo bumwe, abashakashatsi baha methylene blue imbeba zifite amara manini yangijwe n'imiti, bagapima niba ububyimbirwe bugabanuka. Mu bundi, umuganga ukoresha endosikopi atera irangi ry'ubururu ryavanzwe n'amazi ku gice gitwikiriye imbere mu mara y'umuntu ufite ububyimbirwe bw'urura runini bufite ibisebe cyangwa ububyimbirwe bw'urura runini buterwa na Crohn, kugira ngo abone neza uduce duteye amakenga. Ubwa mbere busuzuma niba iyo molekile ihindura indwara. Ubwa kabiri busuzuma niba ibara riyigaragaza. Abasoma bashaka ibimenyetso ku ikoreshwa rya methylene blue mu bubyimbirwe bw'urura runini bufite ibisebe bakeneye ko izi nkuru zombi zitandukanywa, kuko kuzivanga bihindura uburyo bwo koroshya kubona uduce bukaba ubuvuzi butabaho.

Igerageza ryagerageje guhindura ububyimbirwe

Igerageza ryo kuvura ni ubushakashatsi bwo mu 2015 bwakozwe ku mbeba na Dinc na bagenzi be, bwasohowe bwitwa methylene blue ibuza inzira y'ububyimbirwe bw'urura runini buterwa na aside asetike. Ryari igerageza ryo mbere yo kugerageza ku bantu, aho amatsinda yashyizweho ku buryo bwa tombola, si igerageza ku barwayi. Imbeba mirongo inani z'ingabo zo mu bwoko bwa Sprague-Dawley zagabanyijwe mu matsinda ane ya makumyabiri: izima zo kugereranyaho, izima zahawe irangi, izifite ububyimbirwe bw'urura runini zitavuwe, n'izifite ubwo bubyimbirwe zavuwe. Ububyimbirwe bw'urura runini bwatewe na aside asetike, kandi inyamaswa zo mu matsinda yavuwe zahawe 2 mL z'umuti wa methylene blue ufite ubukana bwa 1%. Nyuma y'iminsi itatu, itsinda ryasuzumye igice cya 8 cm cyo ku mpera y'urura runini.

Ibipimo byakoreshejwe byarebaga uburyo butandukanye bw'iyangirika: amanota y'iyangirika rigaragara n'irigaragarira kuri mikorosikopi, urugero ibintu bishobora kunyura mu rukuta rw'amara, ibikorwa by'uturemangingo twa neutrophils bipimwa hakoreshejwe myeloperoxidase, kwangirika kw'ibinure bitewe n'ikorwa rya perokiside bipimwa hakoreshejwe malondialdehyde, imisemburo irwanya okisidasiyo ya superoxide dismutase na catalase, poroteyine zitanga ubutumwa hagati y'uturemangingo za TNF-alpha, IL-1beta na IL-6, n'ibipimo by'inzira ya nitric oxide birimo igiteranyo cya nitrite/nitrate n'ibikorwa by'umusemburo wa nitric oxide synthase.

Aside asetike yateye iyangirika ryari ritegerejwe. Muri iyo mimerere, imbeba zifite ububyimbirwe bw'urura runini zahawe irangi zagaragaje iyangirika rito haba ku buryo bugaragara no kuri mikorosikopi, urugero rwiza kurushaho rw'ibintu bishobora kunyura mu rukuta rw'amara, myeloperoxidase na malondialdehyde nke, superoxide dismutase na catalase byasubiye ku rugero rwabyo, ndetse na cytokines, nitrite/nitrate n'ibikorwa bya synthase byagabanutse. Abanditsi batanze igitekerezo cy'uko uburyo bw'ingenzi bwabiteye ari ukubuza ikorwa rirenze urugero rya nitric oxide, hakiyongeraho kugabanuka kw'iyangirika riterwa n'imyitwarire ya ogisijeni na azote mu turemangingo. Icyo ni igitekerezo gihuje n'ubu buryo bw'igerageza, kandi isuzuma rusange ry'ibimenyetso ku bubyimbirwe ribishyira mu bindi byagaragaye muri laboratwari, aho kubifata nk'ibimenyetso byemejwe ku barwayi.

Ibyo ubu bushakashatsi butakoze ni byo bifite agaciro kurushaho. Bwamaze iminsi itatu, bukoresha imbeba z'ingabo gusa, bugerageza gahunda imwe idahinduka butagereranyije uko ibisubizo bihinduka bitewe n'ingano yatanzwe, ntibushyiramo umuti usanzwe wa IBD wo kugereranyaho, kandi bupima ibipimo by'inyama z'umubiri n'ibinyabutabire nk'ibisimbura ibisubizo by'ubuvuzi, aho gupima ituza ry'indwara, kongera kugaruka kwayo, cyangwa ikindi gisubizo ku murwayi. Kugeza muri Nzeri 2026, nta gerageza ryasohowe ku bantu risuzuma methylene blue nk'umuti w'ububyimbirwe bw'urura runini bufite ibisebe cyangwa w'indwara ya Crohn, ripima ibisubizo by'ubuvuzi. Ibyagaragaye ku mbeba ni intangiriro y'ubushakashatsi, si ishingiro ryo kwifatira ibyemezo ku ngano umuntu yakoresha.

Impamvu gutwikwa n'umuti ari uburyo budahagije bwo kwigana IBD

Ububyimbirwe bw'urura runini buterwa na aside asetike ni uburyo bwo kwigana igikomere, si uburyo bwo kwigana indwara nk'uko iba mu bantu. Umuti utwika uruhu rworoshye rutwikiriye imbere ku mpera y'urura runini, uturemangingo twa neutrophils tukahagera vuba, ibisebe bikabaho, maze inyamaswa igasuzumwa mu minsi mike. Ububyimbirwe bw'urura runini bufite ibisebe mu bantu ni indwara idakira, igenda igaruka, iterwa n'imikorere y'ubudahangarwa. Igira aho ihurira n'irondakoko, utunyabuzima tuba mu mara, n'ubudahangarwa umuntu avukana n'ubwo agenda yunguka, ikarushaho gukara cyangwa igatuza mu gihe cy'imyaka. Ubu buryo bw'igerageza bwigana bimwe mu miterere yo ku mpera y'urura runini n'ibipimo by'ububyimbirwe, ariko ntibwigana hafi na gato uko indwara itangira, ikomeza kubaho cyangwa yongera kugaruka.

Ku ndwara ya Crohn, iryo tandukaniro rirushaho kwiyongera. Igikomere giterwa na aside asetike kiba ku mpera y'urura runini kandi kiguma mu gice gitwikiriye imbere mu rura no mu gice kiri munsi yacyo. Crohn ishobora kwibasira igice icyo ari cyo cyose cy'urwungano ngogozi, igateza ibikomere bitatanye hagati y'uduce tutarwaye, ikagera mu byiciro byose bigize urukuta rw'amara, kandi igahindura inyama z'umubiri zikavamo ahantu hafunganye n'imiyoboro idasanzwe ihuza ibice by'umubiri. Bityo, ibibazo byerekeye methylene blue n'indwara ya Crohn ntibishobora gusubizwa no gutwika impera y'urura runini rw'imbeba mu igerageza ry'iminsi itatu. Ubushakashatsi bufitanye isano n'ubwo, bukorerwa ku nyamaswa kandi bukareba amatsinda y'utunyabuzima, bugomba gusobanurwa mu mwihariko wabwo, uvugwa mu nyoborabushakashatsi ku tunyabuzima two mu mara y'imbeba.

Ihame ryo gukurikiza riroroshye. Iyo hari igitekerezo gishingiye ku buryo bwo guteza ububyimbirwe bw'urura runini mu igerageza, baza umuti wakoreshejwe, ubwoko bw'inyamaswa n'igitsina cyazo, igihe igerageza ryamaze, niba hari ubuvuzi busanzwe bwakoreshejwe mu kugereranya, n'ubwo ibipimo byari iby'inyama z'umubiri cyangwa iby'ibisubizo by'ubuvuzi. Uburyo busubiza uko urura runini rw'imbeba rwagaragaragaho ububyimbirwe ku munsi wa gatatu ntibushobora gusubiza niba indwara y'umuntu ikomeza kuba ituje mu kwezi kwa cumi na kabiri.

Ubushakashatsi bwarebye gusa

Inyandiko ya kabiri ishingiye ku kindi gitekerezo. Marion na bagenzi be bakoze ubushakashatsi bwakurikiranye abantu 102 bafite ububyimbirwe bw'urura runini bumaze igihe kirekire, bagamije kugenzura imikurire idasanzwe y'uturemangingo. Muri bo, 79 bari bafite ububyimbirwe bw'urura runini bufite ibisebe, naho 23 bafite ububyimbirwe bw'urura runini buterwa na Crohn. Bwatangajwe bwitwa gufata utunyama twatoranyijwe hakoreshejwe endosikopi n'irangi biruta uburyo busanzwe bwo kugenzura. Ibisubizo bya buri murwayi byagereranyijwe hagati yabyo mu isuzuma rimwe, aho endosikopi y'urura runini yanyujijwe kabiri. Itsinda ryagereranyije uburyo busanzwe bwo gufata utunyama ahantu hatatoranyijwe, gufata utunyama twatoranyijwe ku hantu hadasanzwe habonetse hakoreshejwe urumuri rwera rusanzwe, no gufata utunyama twatoranyijwe nyuma yo gutera methylene blue ya 0.01% mu rura runini rwose. Umuganga umwe w'inzobere mu gusuzuma indwara z'urwungano ngogozi binyuze mu turemangingo yasuzumye utunyama atazi uburyo buri kamwe kafashwemo.

Gutoranya ahafatwa utunyama hifashishijwe irangi byabonye imikurire idasanzwe y'uturemangingo mu barwayi 17, ugereranyije na 3 mu buryo bwo gufata utunyama ahantu hatatoranyijwe; iryo tandukaniro ryari rifite ubusobanuro mu mibare. Byagereranyijwe kandi n'abarwayi 9 babonetse hakoreshejwe urumuri rwera rwonyine mu gutoranya. Uko kwiyongera mu mubare ntikwageze ku rugero rusanzwe rufatwa nk'urufite ubusobanuro mu mibare. Uburyo bwo gutoranya bwahujwe bwabonye imikurire idasanzwe y'uturemangingo mu barwayi 20, ugereranyije na 3 mu buryo bwo gufata utunyama ahantu hatatoranyijwe. Nta ngaruka mbi zatangajwe.

Nta kintu na kimwe hano cyagerageje ubuvuzi. Irangi ryashyirwaga ku buso bw'inyama z'umubiri kugira ngo ritandukanye imiterere yazo, ritume boroha kubona ahantu imiterere y'utwobo duto itari isanzwe no kuhafata utunyama two gusuzuma. Ubushakashatsi ntibwapimye ibimenyetso by'indwara, ubukana bwayo, urugero rwa cytokines, ituza ry'indwara cyangwa kongera kugaruka kwayo, kandi ntibushobora kwifashishwa nk'ikimenyetso cyo ku bantu cy'uko methylene blue ivura IBD. Icyapimwaga ni ukugaragaza uduce tudasanzwe. Ibyo bijyana n'inyoboraburyo ya endosikopi y'urwungano ngogozi n'endosikopi ikoresha irangi, isobanura gusiga irangi ku turemangingo tukiri tuzima, uburyo bwa Lumeblue bukozwe nk'ikinini kimirwa, n'impamvu kubona ibikomere atari ukubivura.

Igikorwa cyo guhindura indwara ugereranyije no kuyigaragaza: imbonerahamwe y'ibimenyetso

Uko wasuzuma ikindi gitekerezo kijyanye na IBD

Fata buri gitekerezo nk'umwitozo muto wo gushyira ibintu mu byiciro. Icya mbere, menya uruhare: ese irangi ritangwa kugira ngo rihindure imikorere y'umubiri, cyangwa rishyirwa ku nyama z'umubiri kugira ngo zisuzumwe? Icya kabiri, menya indwara: ububyimbirwe bw'urura runini bufite ibisebe bugarukira mu rura runini si kimwe n'indwara ya Crohn, igira ibikomere bitatanye n'ingaruka zigera mu byiciro byose by'urukuta rw'amara; ibyabonetse muri imwe ntibihita bikoreshwa ku yindi. Icya gatatu, menya urwego: uburyo bwo guteza indwara mu mbeba hakoreshejwe imiti, ubushakashatsi bwo kugaragaza uduce tudasanzwe mu bantu, n'igerageza ry'ubuvuzi ku bantu bisubiza ibibazo bitandukanye kandi ntibishobora gusimburana. Icya kane, suzuma ibipimo: ibipimo by'inyama z'umubiri n'imibare y'uduce twabonetse ni ibipimo bisimbura ibisubizo by'ubuvuzi, mu gihe ituza ry'indwara, kongera kugaruka kwayo, gushyirwa mu bitaro no kubagwa ari byo bisubizo bigira ingaruka ku buzima bw'abarwayi. Igitekerezo cyujuje ibyo bipimo bine gikwiye kwitabwaho. Igikoresha imibare y'uduce twabonetse mu bushakashatsi bwa Marion kugira ngo gishyigikire icyemezo cyo kuvura nticyuzuza igipimo cya mbere, kandi gikwiye gushyirwa ku ruhande.

Iby'ingenzi wakuramo

Gira ibyiciro bibiri kandi ntukavange ibibirimo. Icya mbere kirimo igerageza rigufi ku mbeba, aho methylene blue yagabanyije ibipimo by'iyangirika ry'urura runini ryatewe n'imiti. Inzira ya nitric oxide ni yo ikekwa cyane nk'uburyo bwabiteye, ariko ibyo bigendana n'imbogamizi zose zo kwimurira ku bantu ibyavuye mu buryo bw'igerageza bw'igihe gito. Icya kabiri kirimo ubushakashatsi bwo kugenzura abantu, aho irangi ry'ubururu ryafashije abaganga bakoresha endosikopi kubona imikurire idasanzwe y'uturemangingo ikwiye gufatwaho utunyama two gusuzuma, ariko butatanze amakuru na make ku kuvura indwara z'amara. Kugira ngo umenye muri rusange ikoreshwa ryemewe n'irikiri mu igerageza, reba incamake y'ikoreshwa rya methylene blue mu buvuzi. Icyegeranyo cy'ubushakashatsi kuri methylene blue gitondeka ubushakashatsi bushingirwaho mu gutandukanya ibyo byiciro.
