Olina obulwadde obutatera kulabika nga bukosa ‘white matter’ y’obwongo bwo? Ka twogere ku bulwadde bwa Leukodystrophy!

Wali owuliddeko ku kigambo ‘Leukodystrophy’? Kiyinza okuwulikika ng’ekyewuunyisa katono era nga kizibu okwatula, nedda? Naye eno mboozi ekwata ku bulwadde obutatera kulabika obukosa obusimu bwaffe naddala obwongo n’omugongo, naye nga kikulu nnyo ffenna okukimanya. Oluusi tweraliikirira nnyo singa omuntu atuli ku lusegere, omwana omuto, afuna embeera eno. Kale, ka twogere ku kino mu ngeri ennyangu leero, mu ngeri gy’osobola okutegeera.

Obulwadde bwa leukodystrophy buno kye ki?

Mu ngeri ennyangu, obulwadde bwa leukodystrophy kibinja kya buzibu bw’obusimu obutatera kulabika. Obusimu obuli mu bwongo bwaffe n’omugongo (obulinga waya z’amasannyalaze) bwetooloddwa ekibikka ekikuuma, ekiziyiza omuliro ekiyitibwa myelin . Myelin ono ayamba obubaka bw’obusimu okutambula obulungi era mu bwangu. Abasawo era oluwuzi luno olwa myelin bayita ekintu ekyeru.

Kirowoozeeko ng’ekikuta ky’akaveera ekyetoolodde waya y’amasannyalaze. Singa ekikuta ekyo kyonooneka, amasannyalaze tegatambula bulungi, era gayinza n’okuleeta ‘okumpi’. Mu ngeri y’emu, ekikuta kino ekikuuma ekiyitibwa myelin bwe kyonoonese, oba bwe kitakola bulungi, obutoffaali bwaffe obw’obusimu tebusobola kuwuliziganya bulungi. Obubaka tebuyita bulungi. Ekibaawo mu bulwadde bwa leukodystrophy kiri nti myelin eno eyonooneka buli kiseera. Kino kireeta okufiirwa emirimu mu nkola y’obusimu okugenda mu maaso. Empuliziganya wakati w’obwongo n’omubiri gwonna emenyeka.

Embeera eno ya bulijjo etya?

Mu butuufu, obulwadde bwa leukodystrophy si mbeera ya bulijjo nnyo. Ebika byonna eby’obulwadde bwa leukodystrophy tebitera nnyo. Ng’ekyokulabirako, mu Amerika ne Canada, ebika byonna eby’obulwadde bwa leukodystrophy bwe bigattibwa awamu bikwata wakati w’omu ku baana 6,000 n’omu ku buli 100,000 abazaalibwa nga balamu. Mu mawanga ga Asia, kigambibwa nti obulwadde buno butono nnyo nga basatu ku buli 100,000 abazaalibwa nga balamu.

Bubonero ki obulaga obulwadde bwa leukodystrophy?

Eno y’esinga okukaluba. Kubanga obubonero bw’obulwadde bwa leukodystrophy busobola okwawukana ennyo. Obubonero era bwawukana okusinziira ku kika ky’obulwadde. Kyokka, mu bika by’obulwadde bwa leukodystrophy ebisinga obungi, wabaawo okukendeera mpolampola mu nkola y’obusimu . Kino kiyinza okuvaako obubonero obw’enjawulo. Si buli muntu nti ajja kuba n’obubonero bwonna.

Okutwaliza awamu, embeera zino zisobola okukosa ebintu nga:

• Bbalansi ng’otambula: Obutasobola kutambula bulungi, okugwa ennyo.
• Amaanyi: Okuwulira ng’ebitundu byo bigenda bizimba, okukaluubirirwa okusitula oba okukwata ebintu.
• Okutegeera: Okukaluubirirwa okuyiga, okujjukira, n’okussa ebirowoozo ku kintu.
• Okulya n’okumira: Okukaluubirirwa okumira emmere, okuziyira ennyo.
• Okuwulira: Okubulwa okuwulira.
• Entambula n’okukwasaganya: Obutasobola kufuga bulungi bitundu by’omubiri, okukaluubirirwa okukola emirimu mu ngeri entegeke.
• Okwogera: Okwogera obubi, obutasobola kwogera bulungi bigambo oba okufiirwa obusobozi bw’okwogera mpolampola.
• Okulaba: Okunafuwa kw’okulaba, oluusi okubulwa ddala okulaba.

Lowooza ku kino, bw’oba ​​omwana muto, omwana wo ayinza okukula mpola okusinga abaana abalala. Bayinza okulwawo okuyiga ebintu ebipya, okuzannya, n’okwogera. Bino byonna bibaawo kubanga myelin eyonoonese, era obubaka obuva mu bwongo okutuuka mu mubiri tebutambula bulungi.

Ebika ebikulu ebiwerako eby’obulwadde bwa leukodystrophy

Kati abanoonyereza bazudde ebika by’obulwadde bwa leukodystrophy ebisoba mu 50 . Era bakyazuula ebika ebipya. Buli kika kya leukodystrophy kiva ku nkyukakyuka mu buzaale ey'enjawulo . Kwe kugamba, enkyukakyuka mu buzaale mu mubiri gwaffe. Ate era, buli kika kirina obubonero obw’enjawulo. Emyaka gy’okutandika obubonero nagyo gyawukana okusinziira ku kika.

Ka tulabe ebyokulabirako ebimu. Okuva bwe kiri nti kyanditwalidde ekiseera ekiwanvu ennyo okunnyonnyola ebika bino byonna, tujja kwogera ku bitono ku bikulu.

• Adrenoleukodystrophy (ALD): Kino kikosa ebintu ebyeru eby’obwongo n’omugongo, wamu n’endwadde z’omugongo ezifuga obusimu bwaffe. Obubonero butera okutandika mu buto oba nga bukyali. Oyinza okwetegereza ebintu nga obuzibu mu kuyiga, enkyukakyuka mu kulaba oba mu kuwulira, obuzibu mu kutambula, obukoowu, n’okugejja.

• Adult-onset autosomal-dominant leukodystrophy (ADLD): Kino kitera okulabika mu bantu abali mu myaka gyabwe egy’obukulu 40 oba 50. Kireeta obuzibu mu maanyi, entambula n’okutegeera. Era kiyinza okukosa ebintu nga puleesa n'okukuba kw'omutima .

• Obulwadde bwa Alexander: Kino kireetera abaana okulwawo okukula, okukonziba n’okukaluubirirwa okutambula. Butera okukwata abalongo oba abaana abato. Wabula waliwo ebika by’obulwadde bwa Alexander ebimu ebiyinza okuleeta obubonero mu bantu abakulu.

• Obulwadde bwa Canavan:Mu mbeera eno, n’okukula kw’omwana kulwawo, omubiri ne gunafuwa, kizibu okumira emmere, okukonziba kubaawo, omwana aba tateredde buli kiseera, era enkyukakyuka mu kulaba ziyinza okubaawo. Obubonero butera okulabika mu buwere. Wabula waliwo ebika by’endwadde z’embwa ezimu eziraga obubonero oluvannyuma.

• Obulwadde bwa Krabbe: Era buyitibwa globoid cell leukodystrophy . Obubonero butera okutandika mu buwere. Mulimu obunafu, okukaluubirirwa okuyonsa, obutawummula, okulwawo okukula, obulwadde bw’obusimu ( okuziyira n’okuwunya mu bitundu by’omubiri ebikoma), n’okukonziba. Oluusi obubonero buyinza okulabika ng’akyali muto.

• Metachromatic leukodystrophy: Kino kiyinza okubaawo mu baana abawere, abaana abato oba n’abantu abakulu. Kiyinza okuleeta enkyukakyuka mu bukugu mu kulowooza, enneeyisa, okulaba oba okuwulira, okukonziba, obulwadde bw’obusimu, okubulwa amagezi (okubulwa ddala okujjukira), n’okuziba amaaso.

Waliwo ebika ebirala bingi, gamba nga Cerebrotendinous xanthomatosis (CTX) , Childhood ataxia with central nervous system hypomyelination (CACH) (era eyitibwa vanishing white matter (VWM) disease ), Pelizaeus-Merzbacher disease (PMD) (okusinga okukwata abalenzi), n’obulwadde bwa Refsum .

Lwaki obulwadde bwa leukodystrophy bubaawo?

Ensonga enkulu lwaki kino kibaawo y’enkyukakyuka mu buzaale. Kwe kugamba, enkyukakyuka mu DNA mu mibiri gyaffe. Enkyukakyuka zino zibeerawo mu buzaale obulagira okutondebwa kw’ekibikka kino eky’obukuumi ekiyitibwa myelin, oba engeri gye kikola obulungi. Awatali kibikka kino ekikuuma, obutoffaali bw’obusimu tebusobola kukola bulungi.

Enkyukakyuka zino mu buzaale oluusi zisobola okusikira abazadde okutuuka ku baana baabwe. Kwe kugamba, zisobola okuyisibwa okuyita mu milembe. Kyokka, oluusi enkyukakyuka zino nazo zisobola okubaawo mu ngeri ey’ekifuulannenge, ng’obutoffaali bwe bukula ne bwe bwawukana.

Ekikulu, abantu abamu bayinza okuba n’enkyukakyuka mu buzaale (gene mutation) ekivaako obulwadde bwa leukodystrophy naye nga tebafuna bulwadde buno. Tubayita abasitula. Kyokka, abasitula bano basobola okuyisa enkyukakyuka eno mu baana baabwe. Bw’oba ​​ng’olina enkyukakyuka mu buzaale ereeta obulwadde bwa leukodystrophy, oyinza okulowooza ku kubuulirira ku buzaale . Omukugu mu kubuulirira ku buzaale ajja kutunuulira ebyafaayo by’amaka go era akuyamba okuzuula akabi akali mu kuyisa enkyukakyuka eno mu baana bo.

Waliwo ebintu byonna eby’akabi ebikosa kino?

Mu butuufu, tewali nsonga za bulabe ntongole eziyinza okuziyiza obulwadde bwa leukodystrophy. Kino kiri bwe kityo kubanga kya buzaale. Wabula amawanga agamu kizuuliddwa nga gasingako katono okulwala ebika ebimu eby’obulwadde bwa leukodystrophy. Ebika bya leukodystrophy ebisinga bikosa ekikula kyombi kyenkanyi. Wabula ebika ebimu, gamba nga Pelizaeus-Merzbacher disease (PMD) bisinga kukwata balenzi.

Obulwadde bwa leukodystrophy buzuulibwa butya?

Omusawo ajja kusooka kukubuuza ku bubonero bwo era akubuuze ku byafaayo by’obulamu bwo obw’obuntu n’obw’amaka go. Oluvannyuma bajja kukola okukebera omubiri n’okukeberebwa obusimu.

Osobola n’okukola ebigezo ebirala ebitonotono:

• Okukebera abalongo: Mu nsi ezimu, okukebera kuno kukozesebwa okuzuula ebika ebimu eby’obulwadde bwa leukodystrophies.
• Okukebera omusaayi n’amalusu ( genetic testing ): Bino bisobola okuzuula enkyukakyuka mu buzaale mu DNA yo.
• Okukebera ebifaananyi: Okugeza , MRI scan esobola okukolebwa okutunuulira embeera y’ebintu ebyeru mu bwongo n’omugongo.

Wadde nga bino byonna bikebereddwa, okuzuula obulwadde bwa leukodystrophy oluusi kiyinza okuba ekizibu kubanga obubonero bwa njawulo nnyo. Oluusi, embeera nnyingi ez’obulwadde bwa leukodystrophy tezizuulibwa.

Bujjanjabi ki obw’obulwadde bwa leukodystrophy?

Kino kye kintu ekisinga obukulu ffenna kye tulina okumanya. Tewali ddagala lya leukodystrophy n’okutuusa kati. Naye ekyo tekitegeeza nti tewali kye tuyinza kukola. Waliwo ebintu bingi bye tuyinza okukola okufuga obubonero, okwanguyiza obulamu katono, n’okukuuma ezimu ku mirimu gy’obusimu.

Obujjanjabi buno buyinza okuli:

• Eddagala eriwonya okukonziba, okunywezebwa kw’ebinywa, n’obuzibu mu kutambula.
• Obujjanjabi bw’endya oba okukozesa obupiira bw’okuliisa ku buzibu mu kulya n’okumira.
• Obujjanjabi bwa hormone ku bizibu by’enkola y’endwadde z’ekibumba.
• Okujjanjaba omubiri, okujjanjaba emirimu, n’okujjanjaba okwogera okutumbula obukugu ng’okutambula, okutebenkeza, n’okwogera.

Obujjanjabi bw’obuzaale bujjanjabi bupya eri ebika ebimu eby’obulwadde bwa leukodystrophies. Kizingiramu okuyingiza obuzaale mu butoffaali okukyusa engeri gye bukolamu obutoffaali obumu.

Okusimbuliza obutoffaali obusibuka oba okusimbuliza obusigo bw’amagumba kiyinza okulongoosa obubonero bw’ebika ebimu eby’obulwadde bwa leukodystrophy. Wabula obujjanjabi buno bukola bulungi mu misango emitono ennyo. Singa obulwadde bwa cerebrotendinous xanthomatosis (CTX) buzuulibwa nga bukyali, obujjanjabi obuyitibwa chenodeoxycholic acid (CDCA) busobola okukozesebwa okubujjanjaba.

Okugatta ku ekyo, waliwo okugezesebwa okuwerako okugenda mu maaso mu kiseera kino okuzuula obujjanjabi bw’ebika ebimu eby’obulwadde bwa leukodystrophy. Kale, bw’oba ​​ggwe oba omwana wo mulina embeera eno, osobola okwogera n’omusawo wo okulaba oba enkola eno empya ey’obujjanjabi ekusaanira.

Obulamu obusuubirwa mu bulwadde bwa leukodystrophy bwe buliwa?

Guno mulamwa muzibu era gwa maanyi okwogerako. Obulwadde bwa Leukodystrophy bulwadde obugenda bweyongera obuleeta obuzibu ku busimu oluvannyuma lw’ekiseera. Abaana bangi abalina obulwadde bwa leukodystrophy bafa nga tebannatuuka mu myaka gya bukulu. Kyokka, abantu abamu bawangaala okutuuka mu myaka egy’obukulu. Wadde ng’endwadde zino zitera okutta abantu, obujjanjabi obupya n’okugezesebwa mu malwaliro bireese essuubi eri abo abalina obulwadde buno.

Ebintu ebikulu bye twetaaga okujjukira (Take-Home Message) .

Leukodystrophy bulwadde obutatera kulabika, obusikira mu nkola y’obusimu. Kwonoona ekibikka ekikuuma ekiyitibwa myelin ekyetoolodde obusimu mu bwongo n’omugongo. Awatali myelin, obusimu tebusobola kuwuliziganya bulungi, ekivaamu obubonero obw’enjawulo.

Wadde kino tekinnaba kujjanjaba, waliwo eddagala n’obujjanjabi obw’enjawulo okufuga obubonero n’okwanguyiza obulamu. Okunoonyereza okupya kulaga nti bifunye obuwanguzi mu kujjanjaba embeera zino. Jjukira nti ttiimu y’abasawo y’omwana wo bulijjo ebeera naawe, ng’ewa omwana wo obujjanjabi obusinga obulungi. Kikulu nnyo obutasattira, okunoonya amagezi g’abasawo nga bukyali n’okumanya amawulire amatuufu.
