Ese uzi Beta Thalassemia? Reka tubiganireho mu buryo bworoshye!

Ese wigeze wumva indwara yitwa 'thalassemia'? Wenda hari umuntu wo mu muryango wawe cyangwa inshuti yawe ufite iyi ndwara. Mu by'ukuri iyi ni indwara ifitanye isano n'amaraso yacu. Uyu munsi tugiye kuvuga ku bwoko bumwe bw'ingenzi bwa thalassemia , Beta Thalassemia . Nubwo iri zina rishobora kumvikana nk'irigoye, turarivugaho mu buryo bworoshye, mu buryo ushobora kumva.

Beta Thalassemia ni iki?

Muri make, beta thalassemia ni indwara y'amaraso aho umubiri wacu udashobora gukora hemoglobin neza. Noneho ushobora kuba wibaza uti "Hemoglobine ni iki?" Hemoglobine ni poroteyine iboneka mu turemangingo dutukura tw'amaraso yacu irimo icyuma kinini. Mu by'ukuri, ni yo ngingo nyamukuru igize uturemangingo dutukura tw'amaraso.

Tekereza kuri ubu buryo: hemoglobine ni nk'imodoka ifasha uturemangingo dutukura tw'amaraso yacu gutwara ogisijeni. Utwo turemangingo dutukura tw'amaraso dutwara ogisijeni mu tundi turemangingo no mu ngingo z'umubiri wose. Rero, uturemangingo twacu dukoresha uwo mwuka kugira ngo dukore ingufu.

Beta thalassemia ni bumwe mu bwoko bubiri bw'ingenzi bwa thalassemia. Muri ibi, hari impinduka zimwe na zimwe (mutations ya gene), ni ukuvuga ikosa rito, mu ngirabuzimafatizo ziri muri poroteyine yacu ya hemoglobine. Kubera iri kosa rya ngirabuzimafatizo, umubiri wacu ntushobora gukora neza poroteyine ya beta-globin muri hemoglobine.

Ni gute beta thalassemia igira ingaruka ku mubiri wanjye?

Iyo umubiri wacu ugabanutse, uturemangingo dutukura tw’amaraso turangirika. Hanyuma utwo turemangingo dutukura twangiritse dukurwa mu maraso vuba. Noneho tekereza, bigenda bite iyo uturemangingo dushya dutukura tudashobora gusimbuza utwatakaye? Icyo gihe ni bwo amaraso abura amaraso cyangwa kubura amaraso.

Ibimenyetso bya anemia bibaho iyo tudafite uturemangingo dutukura duhagije two gutwara ogisijeni mu ngingo z'umubiri wacu. Icyo gihe utwo turemangingo ntitubona ogisijeni ihagije. Ibimenyetso bya anemia bizana na beta thalassemia bishobora kuva ku byoroheje kugeza ku bikomeye , bitewe n'uburyo uturemangingo dutukura tw'amaraso yawe turi hasi.

Ni nde uri mu kaga gakomeye ko kurwara beta thalassemia?

Beta thalassemia ni indwara iterwa n’uturemangingo tw’umubiri ivukanwa . Ibi bivuze ko abana bavukana ubusembwa bw’uturemangingo bujyanye n’iyi ndwara babikuye ku babyeyi babo. Abantu benshi bafite beta thalassemia baba mu bihugu nka Afurika, akarere ka Mediterane, u Burasirazuba bwo Hagati, Ubuhinde na Aziya y’Amajyepfo y’Uburasirazuba. Ariko, bitewe n’uko abantu benshi bimukira hirya no hino ku isi, abarwayi ba beta thalassemia ubu barimo kugaragara mu majyaruguru y’Uburayi na Amerika y’Amajyaruguru. Iyi ndwara igaragara no mu gihugu cyacu, Sri Lanka.

Beta thalassemia ikunze kugaragara gute?

Ese wari uzi ko thalassemia ari yo mpamvu ikomeye itera amaraso make mu mubiri? Abarwayi bashya ibihumbi na magana ba beta thalassemia basuzumwa buri mwaka. Ariko, inkuru nziza ni uko hamwe n’ingamba zo kwirinda nko gusuzuma abantu bafite ikibazo cya thalassemia, umubare w’abandura waragabanutse ku rugero runaka .

Ni iki gitera beta thalassemia?

Impamvu nyamukuru itera beta thalassemia ni ubusembwa bw’uturemangingo (mutation) bugabanya ikorwa rya beta-globin mu mubiri wacu. Nkuko twabivuze, hemoglobin igizwe n’imiyoboro ine ya poroteyine: imiyoboro ibiri ya alpha-globin n’imiyoboro ibiri ya beta-globin . Ubusembwa buri mu muyoboro wa alpha-globin butera alpha thalassemia, naho ubusembwa buri mu muyoboro wa beta-globin butera beta thalassemia. Iyo hari imwe muri iyi miyoboro ya globin ibuze, uturemangingo dutukura tw’amaraso turangirika kandi tukangirika.

Uragwa indwara ya gene ya beta thalassemia mu buryo bwa autosomal recessive pattern . Ibi bibaho iyo ababyeyi bombi bafite kopi imwe ya gene ifite inenge n'ikopi imwe ya gene isanzwe. Mu bwoko bwa beta thalassemia bukabije, uragwa kopi ya gene ifite inenge ivuye ku babyeyi bombi.

Ariko, gake cyane, beta thalassemia ishobora guterwa no kuragwa gene imwe gusa ya beta-globin ifite inenge. Ibi byitwa autosomal dominant pattern .

Ni ubuhe bwoko bwa beta thalassemia?

Uburemere bw'indwara yawe buterwa n'umubare w'uturemangingo tw'umubiri dufite inenge uvukana n'aho inenge iherereye. Hari inenge zimwe na zimwe zituma nta beta-globin ikorwa na gato (yitwa beta-zero thalassemia ). Hari izindi nenge zituma beta-globin nke cyane ikorwa (yitwa beta-plus thalassemia ).

Hari ubwoko bumwe bw'ingenzi bwa beta thalassemia:

• Beta thalassemia major (Cooley's anemia): Ubu ni bwo bwoko bukomeye bwa beta thalassemia. Muri ibi, utunyangingo twombi twa beta-globin tuba tubuze cyangwa dufite inenge. Beta thalassemia major ubu yitwa "thalassemia iterwa no guterwa amaraso" kuko abantu bafite iyi ndwara baba bakeneye guterwa amaraso ubuzima bwabo bwose.
• Beta thalassemia intermedia: Ibi bishobora gutera amaraso make kugeza ku rugero rwo hagati. Muri iki kibazo, utunyangingo twombi twa beta-globin tuba tubuze cyangwa dufite inenge. Ariko, abantu bafite beta thalassemia intermedia akenshi ntibakenera gutanga amaraso ubuzima bwabo bwose.
• Beta thalassemia ntoya (izwi kandi nka beta thalassemia trait): Iyi ni indwara ikunze gutera amaraso make. Ingirabuzimafatizo imwe gusa ya beta-globin niyo ibura cyangwa ifite inenge. Hari abantu bamwe na bamwe bafite beta thalassemia ntoya bashobora kutagira ibimenyetso.

Ni ibihe bimenyetso bya beta thalassemia?

Ibimenyetso byawe bizaterwa n'uburemere bwa beta thalassemia yawe. Urugero, umuntu urwaye beta thalassemia minor ashobora kuba adafite ibimenyetso cyangwa akaba afite amaraso make cyane. Abantu bafite beta thalassemia intermedia cyane cyane beta thalassemia major bashobora kugira ibimenyetso biri hagati cyangwa bikomeye kurushaho.
