Icyo Metachromatic Leukodystrophy Aricyo? Ibimenyetso, Impamvu, n’Ubuvuzi

Metachromatic leukodystrophy (MLD) ni indwara idasanzwe y’umuzimu iterwa n’impamvu z’umurage, ikangiza urwego rw’ubwonko rukingira imitsi y’ubwonko. Iyi ndwara ibaho iyo umubiri utakonjesha neza amavuta yitwa sulfatides, maze akagira umubare munini ukangiza ibice by’ubwonko n’umugongo.

Tekereza ku mitsi y’ubwonko nk’insinga z’amashanyarazi zifite agakingirizo. Muri MLD, iki kingirizo kirasenyuka buhoro buhoro, bigatuma urwego rw’ubwonko rugorana kohereza ubutumwa mu mubiri wose. Nubwo ibi bishobora gutera ubwoba, gusobanukirwa MLD bishobora gufasha wowe cyangwa abakunzi bawe guhangana n’iyi ndwara mufashijwe n’abaganga n’ubuvuzi bukwiye.

Icyo Metachromatic Leukodystrophy Aricyo?

Metachromatic leukodystrophy iri mu itsinda ry’indwara z’ubwonko zibasira ibice by’ubwonko byera. Izina ryayo rikomoka ku buryo imyenda y’ubwonko yanduye isa munsi ya mikoroskopi - igaragaza ibintu byera by’umuhondo-umukara aho kuba umweru usanzwe.

Iyi ndwara irangwa n’umurage, bivuze ko iherwa abana n’ababyeyi binyuze mu mimerere y’imibiri yabo. MLD ibaho iyo umuntu aherwa kopi ebyiri z’ikintu kidakora neza mu mubiri, gisanzwe gifasha gukora enzyme yitwa arylsulfatase A. Iyo iyi enzyme idahagije, ibintu byangiza byinshi bikusanyiriza mu rwego rw’ubwonko buhoro buhoro.

Iyi ndwara igira ingaruka zitandukanye ku bantu bitewe n’igihe ibimenyetso byayo bigaragara. Bamwe mu bana bagaragaza ibimenyetso mu myaka yabo ya mbere y’ubuzima, abandi bakaba batabigira kugeza bakuze. Urugendo rwa buri muntu na MLD ni rwihariye, kandi iterambere mu buvuzi rikomeza gutanga ibyiringiro bishya mu gucunga no kuvura iyi ndwara.

Ubwoko bwa Metachromatic Leukodystrophy

MLD igabanyijemo ubwoko butatu bushingiye ku gihe ibimenyetso bigaragara. Gusobanukirwa ubwoko bw’iyi ndwara bifasha abaganga gutanga ubuvuzi bukwiye kandi bifasha imiryango kumenya icyo yitega.

MLD y’abana bato ni yo ndwara ikunze kugaragara kandi ikomeye. Ibimenyetso byayo bisanzwe bigaragara hagati y’amezi 6 n’imyaka 2. Abana bashobora gutakaza ubushobozi bari basanganywe, nko kugenda cyangwa kuvuga.

MLD y’abakiri bato isanzwe itangira hagati y’imyaka 3 na 16. Iyi ndwara itera buhoro ugereranyije n’iy’abana bato. Abana bashobora kugorana kwiga, guhindura imyitwarire, cyangwa kugira ibibazo byo guhuza ibikorwa mbere y’uko ibimenyetso bigaragara.

MLD y’abakuze ishobora gutangira igihe icyo ari cyo cyose nyuma y’imyaka 16, rimwe na rimwe itagaragara kugeza umuntu agejeje imyaka 30, 40, cyangwa nyuma yaho. Iyi ndwara isanzwe itera buhoro cyane kandi ishobora kuboneka nk’indwara zo mu mutwe cyangwa izindi ndwara z’ubwonko.

Ibimenyetso bya Metachromatic Leukodystrophy

Ibimenyetso bya MLD bigaragara buhoro buhoro uko ukingirizo rw’imitsi y’ubwonko rusenyuka. Ibimenyetso byihariye n’igihe bigaragara biterwa ahanini n’ubwoko bwa MLD umuntu afite, ariko muri rusange bigira ingaruka ku myanya y’umubiri, gutekereza, n’imyitwarire.

Mu ntangiriro, ushobora kubona impinduka nto zishobora kwitiranywa n’izindi ndwara. Reka turebe ibimenyetso bikunze kugaragara mu matsinda y’imyaka itandukanye:

• Gukora ikibazo cyo kugenda cyangwa kugwa kenshi
