Obeera mweraliikirivu katono ku buzaale bw’omwana wo? Ka twogere ku Trisomy!

Oyinza okuba nga wali owulidde ekigambo "Trisomy" oba omusawo wo ayinza okuba nga yakyogerako. Kya bulijjo okuwulira ng’otya katono n’okwagala okumanya ng’owulira bino. Trisomy kye ki? Lwaki kibaawo? Kinaakwata kitya omwana? Byonna ka twogere mu ngeri ennyangu gy’osobola okutegeera.

Trisomy kye ki? Mu ngeri ennyangu...

Kuba akafaananyi ng’omubiri gwaffe gukoleddwa mu bukadde n’obukadde bw’obutoffaali obutonotono. Munda mu buli katoffaali, mulimu ekifo ekiringa ekifo ekifuga akatoffaali ako, kye tuyita nyukiliya . Munda mu nyukiliya eyo mulimu ebintu ebiyitibwa `Chromosomes` . Bino biringa bitabo. Buli kimu ekikwata ku mubiri gwaffe, buli ngeri etufuula ab’enjawulo ku balala (nga obuwanvu, langi, langi y’enviiri, langi y’amaaso) biwandiikibwa mu bitabo bino ebiyitibwa chromosomes. Amawulire gano ge tuyita `DNA` .

Mu budde obwabulijjo, buli katoffaali mu muntu omulamu obulungi kalina ebibiri 23 ebya chromosomes zino. Ekyo kitegeeza nti omugatte gwa chromosomes 46. Ekitundu ku bino, 23, biva wa maama waffe, ate ekitundu ekirala, 23, biva wa kitaffe.

Kati, wuuno trisomy kye kitegeeza: Oluusi, ng’oggyeeko emu ku babiri ezo, chromosome ey’enjawulo eyongerwako. Olwo omuwendo gwonna ogwa chromosomes gufuuka 47 mu kifo kya 46. "Tri" kitegeeza ssatu, ate "somy" kitegeeza ekintu ekiringa omubiri. Kale, trisomy kuba kuba na chromosomes ssatu yokka nga wandibaddewo bbiri.

Wadde omwana alina chromosome eno ey’enjawulo asobola okuzaalibwa nga mujjuvu, oluusi asobola okuvaamu olubuto mu myezi esatu egisooka ng’ali lubuto.

Bika ki ebikulu eby’obulwadde bwa trisomy?

Abasawo bazuula embeera eno eya trisomy nga basinziira ku chromosome pair ki chromosome ey’enjawulo gy’eri.Olw’okuba buli chromosome pair erina omulimu ogw’enjawulo mu mubiri gwaffe, embeera y’obuzaale bw’omwana ejja kwawukana okusinziira ku chromosome ey’enjawulo gy’eyongerwako.

Embeera ezisinga okutawaanya obulwadde bwa trisomy ze zino:

• Trisomy 21 : Eno y'embeera ffenna gye tumanyi nga Down syndrome . Waliwo chromosome ey’enjawulo mu chromosome pair ey’omulundi ogwa 21.
• Trisomy 18 : Kino era kiyitibwa obulwadde bwa Edward syndrome .
• Trisomy 13 : Kino kiyitibwa obulwadde bwa Patau syndrome .

Mu ngeri y’emu, ensengekera y’obutonde (chromosomes) ey’omulundi ogwa 23 mu buzaale bwaffe y’esalawo ekikula kyaffe. Zino ziyitibwa `XX` ku mukazi ate `XY` ku musajja. Obutoffaali bwe bwawukana, obutali bwa bulijjo mu chromosomes zino ez’okwegatta nabwo busobola okubaawo, ekivaamu trisomies. Eby’okulabirako ku bino bye bino:

• Obulwadde bwa Trisomy X (`Obulwadde bwa Trisomy X` oba `XXX`) .
• Obulwadde bwa Klinefelter (`Obulwadde bwa Klinefelter` oba `XXY`)
• Obulwadde bwa Yakobo (`Obulwadde bwa Yakobo` oba `XYY`) .

Ani asinga okukosebwa embeera eno eya trisomy?

Mu butuufu, obulwadde bwa trisomy busobola okubaawo ku mutendera gwonna ogw’olubuto. Wabula kizuuliddwa nti akabi kano kasingako katono ng’abakyala abasukka mu myaka 35 bafunye embuto . Kyokka, ekyewuunyisa, abaana abasinga obungi abazaalibwa n’obulwadde bwa trisomy bazaalibwa bazadde abali wansi w’emyaka 35. Kino kiri bwe kityo kubanga, mu bibalo, abaana bangi bazaalibwa abantu abali wansi w’emyaka 35.

Ekisinga obukulu: Trisomy si kintu ekibaawo nga kiyita mu nsobi ya maama oba taata. Ye nkyukakyuka mu buzaale ebaawo mu ngeri ey’ekifuulannenge.

Obulwadde bwa trisomy butera kwenkana wa?

Ekika ky’obulwadde bwa trisomy ekisinga okumanyibwa ye trisomy 21 oba Down syndrome. Ng’ekyokulabirako, mu Amerika yokka, abaana nga 6,000 be bazaalibwa n’obulwadde bwa Down syndrome buli mwaka. Ekyo kitegeeza nti omu ku buli balongo 700.

Bubonero ki obulaga obulwadde bwa trisomy ng’oli lubuto?

Mu kiseera ky’okukebera olubuto lwa ultrasound , omusawo wo ajja kunoonya obubonero bw’obulwadde bwa trisomy. Ebimu ku bubonero buno mulimu:

• Omuwendo gw’amazzi okwetoloola omwana (amniotic fluid) matono nnyo.
• Omusuwa gw’omwana gulina omusuwa gumu gwokka mu kifo ky’omuwendo gw’emisuwa ogwa bulijjo.
• Ensigo ntono okusinga eya bulijjo.
• Entambula z’omwana (okuwuubaala) zirabika nga ntono.
• Omwana alabika nga mutono okusinga emyaka gye gyennyini.
• Ebimu ku bitali bya bulijjo mu mubiri, okugeza, ebizibu by’omutima ebimu oba enjatika mu mumwa.

Bubonero ki obulaga ng’omwana amaze okuzaalibwa?

Obubonero omwana bw’ayinza okufuna buyinza okwawukana okusinziira ku kika ky’obulwadde bwa trisomy. Obubonero obumu obutera okulabika mulimu:

• Okubeera omumpi okusinga ogwa bulijjo (obuwanvu obumpi).
• Feesi eyeetooloovu ne ffeesi empanvu.
• Okutunula okuserengese ku maaso.
• Ennyindo ezikutuse.
• Ebitundu by’omubiri eby’omunda (nga omutima, amawuggwe, ensigo) biyinza obutatondebwa bulungi oba biyinza okuba n’obuzibu mu nkola yaabyo.
• Okulwawo kw’enkulaakulana n’obulemu mu magezi.

Lwaki obulwadde buno obw’ekika kya trisomy bubaawo? Ennyinyonnyola ya ssaayansi ennyo...

Chromosomes mu mibiri gyaffe zikolebwa mu nsengeka eyeetongodde ennyo. Omutendera guno ogw'obutoffaali gulinga "blueprint" y'ekyo kye tuli. Obutoffaali bw’ebitundu by’okuzaala bwe bukolebwa (ensigo mu basajja, amagi mu bakazi), butandikira ku katoffaali kamu akazaala. Olwo akatoffaali kano kayita mu nkola eyitibwa meiosis . Wano obutoffaali obumu we bwawukana emirundi ebiri, ne buvaamu obutoffaali buna. Buli katoffaali akapya kalina ekitundu kya DNA mu katoffaali akasooka, oba chromosomes 23.

Eno y’enkola y’okugabanya obutoffaali (meiosis)., Oluusi obutoffaali busobola okwawukana mu bukyamu. Ekyo bwe kibaawo, kkopi ey’enjawulo ey’akatoffaali ejja ne yeegatta ku bibiri ebiyitibwa chromosomes. Mu budde obwabulijjo, mu buli pair mulina okubaamu chromosomes bbiri. Naye wano, chromosome eyokusatu ekola era ne yeegatta ku babiri abo. Ekyo kiyitibwa trisomy.

Trisomy ebaawo mu kiseera ky'okuzaala . Kino kibaawo mu ngeri ya kimpowooze, tekiva ku kintu kyonna maama kye yakola ng’ali lubuto. Wabula nga bwe kyayogeddwako emabegako, akabi kano kasingako katono eri abo abafuna embuto oluvannyuma lw’emyaka 35.

Obulwadde bwa trisomy buzuulibwa butya?

Okukebera obuzaale ng’oli lubuto kuyinza okukuwa obubonero obulaga nti waliwo obulwadde bwa trisomy. Omwana bw’amala okuzaalibwa, embeera eno ekakasibwa okukeberebwa omubiri n’okukebera obuzaale obulala nga bakozesa omusaayi okuva mu mwana.

Bikebere ki ebikozesebwa okuzuula obulwadde bwa trisomy?

Mu kiseera ky’olubuto, kirabika omusawo ajja kulagira maama wo omusaayi ne bamusika. Nga bwe kyayogeddwako emabegako, sikaani ejja kunoonya ebintu ng’amazzi agasukkiridde okwetooloola omwana, nuchal lucency , n’obuwanvu bw’ebitundu by’omwana. Bino biyinza okuba obubonero obulaga nti omuntu alina obuzibu mu buzaale.

Oluvannyuma lw’okukeberebwa kuno okusookerwako, waliwo ebigezo ebirala ebitongole okukakasa embeera eno:

• Chorionic villus sampling (CVS): Wakati wa wiiki 10 ne 13 ng’oli lubuto, akatundu akatono ak’obutoffaali kaggyibwa mu nnabaana okukebera embeera z’obuzaale n’ekikula ky’omwana.
• Amniocentesis: Wakati wa wiiki 15 ne 20 ng’oli lubuto, akatono ku mazzi g’omu lubuto ageetoolodde omwana atwalibwa okukebera oba waliwo ebizibu by’obulamu ebiyinza okubaawo.
• Okutwala omusaayi mu nnabaana mu lususu (PUBS): Omusaayi omutono guggyibwa mu nnabaana w’omwana okukebera obulamu bw’omwana.
• Non-invasive prenatal testing (NIPT): Oluvannyuma lwa wiiki 10 ng’ali lubuto, omusaayi okuva mu maama gukeberebwa okukebera oba omwana alina obuzibu bwonna mu buzaale.

Embeera z’obulwadde bwa trisomy zijjanjabwa zitya?

Trisomy mbeera ya bulamu bwonna. N’olwekyo, kyetaagisa obujjanjabi obw’ekiseera ekiwanvu okumalawo obubonero obukwatagana n’embeera eno. Obujjanjabi bw’abaana abazaalibwa n’obulwadde bwa trisomy mulimu:

• Okulongoosa okutereeza obuzibu mu mubiri.
• Okuwa obuyambi mu by'enjigiriza .
• Obujjanjabi bw’okwogera, enneeyisa n’omubiri .
• Eddagala okufuga obubonero bw’embeera endala ez’obujjanjabi eziyinza okukula oluvannyuma lw’ekiseera.

Waliwo engeri y’okukendeeza ku bulabe bw’okulwala obulwadde bwa trisomy?

Mu butuufu, embeera z’obuzaale nga trisomy teziyinza kuziyizibwa. Olw’okuba ekikyamu ky’ensengekera y’obutonde (chromosomal defect) kibaawo mu ngeri ey’ekifuulannenge mu kiseera ky’okugabanya obutoffaali, osobola okukendeeza ku bulabe bwo obw’okuzaala omwana alina embeera y’obuzaale ng’okola bino wammanga:

• Okutegeera akabi akali mu kufuna embuto singa oba osukka emyaka 35.
• Okukebera obuzaale nga tonnafuna lubuto.
• Okwewala okukozesa ebintu ebikolebwa mu taaba n’omwenge.
• Faayo ku bulamu bwo ng’olya emmere ennungi era ng’okola dduyiro buli kiseera.

Trisomy eno ejja kukwata etya omwana wange?

Olw'okuba chromosome ey'enjawulo ekyusa "blueprint" y'omwana, eyinza okuleeta obulema mu kuzaalibwa ( gamba ng'ebifaananyi eby'enjawulo mu maaso) n'obulema mu magezi. Abaana bangi abazaalibwa n’obulwadde bwa trisomy 12 bajja kufuna ebizibu ebirala eby’obulamu (nga okukwatibwa endwadde z’amatu enfunda eziwera, obulwadde bw’omutima, n’okusannyalala mu tulo) oluvannyuma lw’okuzuulibwa embeera eno. Kyokka, singa omwana wo ajjanjabiddwa bulungi, asobola okubeera n’obulamu obw’essanyu era obumativu .

Wabula abaana abazaalibwa n’embeera nga Trisomy 18 oba Trisomy 13 balina emikisa emitono egy’okuwangaala okusukka wiiki ezisooka ez’obulamu (ekiseera ky’okuzaalibwa) olw’obuzibu bw’embeera eno (naddala okulwawo oba obutali bwa bulijjo mu nkula y’ebitundu by’omubiri). Omusawo ajja kwekenneenya obulamu bw’omwana wo n’okumuwa obujjanjabi okwongera ku mikisa gy’okuwangaala eri abalongo abazaalibwa n’embeera zino.

Ddi lwe nnina okulaba omusawo?

Ekimu ku bizibu ebiva mu trisomy kwe bulabe bw'okuvaamu olubuto . Kino kitera okubaawo mu myezi esatu egisooka ng’oli lubuto. Bw’oba ​​olina obubonero bwonna obw’okuggyamu olubuto (obuwandiikiddwa wansi), laba omusawo mu bwangu:

• Obulumi mu lubuto olwa wansi, okuzimba.
• Obulumi mu mugongo ogwa wansi.
• Obulumi mu lubuto.
• Okuvaamu omusaayi omutono oba omungi.
• Okufuna omusujja n’okufuna omusujja.

Bibuuzo ki ebikulu by’olina okubuuza omusawo?

Bw’oba ​​olina ekibuuzo ekirala kyonna ku nsonga eno, totya kubuuza musawo wo. Bino bye bimu ku bibuuzo by’oyinza okubuuza:

• Nnyinza ntya okukendeeza ku bulabe bw’okuzaala omwana alina embeera y’obuzaale nga trisomy?
• Kiki ekikeberebwa nga tannazaala ky’ogamba okukakasa oba omwana wange alina embeera y’obuzaale?
• Nsobola okufuna olubuto olulungi oluvannyuma lw’okuzuulibwa nti nnina obulwadde bwa trisomy?

Njawulo ki eriwo wakati wa Trisomy ne Monosomy?

Bino byombi mbeera za buzaale.

• Trisomy kwe kubeerawo kwa kkopi ey’enjawulo eya chromosome.
• Monosomy kwe kubulwa kkopi emu eya chromosome (i.e., okufiirwa chromosome emu).

Embeera zino zombi ez’obuzaale zibaawo nga kiva ku nkyukakyuka mu buzaale ebaawo mu kiseera ky’okugabanya obutoffaali. Obutabeera bwa bulijjo buno tebusobola kuziyizibwa kubaawo mu kiseera ky’okugabanya obutoffaali.

Bye tulina okujjukira okuva mu bye twogeddeko (Take-Home Message)

Okuva bwe kiri nti tewali ngeri yonna gy’oyinza kuziyiza buzaale nga trisomy, bw’oba ​​oteekateeka okufuna olubuto, yogera n’omusawo wo ku kukebera obuzaale okwekenneenya akabi k’okuzaala omwana alina embeera y’obuzaale.

Bw’ozuulibwa ng’olina obulwadde bwa trisomy ng’oli lubuto, tosattira. Waliwo obuwagizi bungi n’ebikozesebwa ebisobola okukuyamba ggwe ne omwana wo okubeera obulamu obulungi, obumatiza. Okubuulirira ku buzaale kuyinza okukuyamba okutegeera embeera y’omwana wo n’okumuwa obujjanjabi n’obuwagizi bwe yeetaaga ng’akula. Jjukira nti toli wekka.
