Okukebera omusaayi gwo kulaga "Blast Cells"? Ka twogere ku nsonga eno!

Oluusi oyinza okulaba ekintu ekiyitibwa "Blast Cells" mu lipoota yo ey'omusaayi. Kya bulijjo okuwulira ng’olina obunkenke obutonotono ng’okirabye. N'okuwulira ekigambo "blast" kiyinza okukutiisa katono. Naye nga tonnafuna bunkenke, ka twogere mu bufunze ku butoffaali buno obw’okubwatuka bwe buli ddala, lwaki bukulu eri emibiri gyaffe, era kiki ekibaawo singa bweyongera obungi?

Obutoffaali obuyitibwa blast cells kye ki? Ekyo kyokka ky’olina okumanya?

Yee, kikulu okumanya kino. Mu ngeri ennyangu, obutoffaali obuyitibwa blast cells kika kya butoffaali buto obutakuze, oba obutakula mu bujjuvu, mu mubiri gwaffe. Buno bwe butoffaali obuzaala ebika by’obutoffaali eby’enjawulo mu mubiri gwaffe. Naye bw'ofuna lipoota ya laabu egamba nti "blasts," kitera okutegeeza obutoffaali bw'omusaayi obutakuze. Kubanga abakugu mu by’omusaayi n’obulwadde bwa kookolo bakozesa ebintu ng’omuwendo gw’obutoffaali obuyitibwa blast cells mu musaayi gwo okuzuula endwadde ezimu ezeekuusa ku musaayi, gamba ng’obulwadde bwa acute leukemia.

Bw’oba ​​olina obutoffaali obuyitibwa blast cells obutali bwa bulijjo oba omuwendo omunene mu musaayi gwo, kiyinza okuba akabonero akalaga nti waliwo kookolo w’omusaayi. Y’ensonga lwaki kino olina okukifaako.

Kale, njawulo ki eriwo wakati w’obutoffaali obusibuka mu musaayi n’obutoffaali obuyitibwa blast cells?

Kino kiyinza okulabika ng’ekizibu katono, naye mu butuufu kyangu nnyo. Lowooza ku kino, gino gyombi mitendera mikulu mu nkula y’obutoffaali bwaffe.

Obutoffaali obusibuka mu musaayi bulinga obutoffaali bwa maama obuzaala ebika by’obutoffaali ebirala byonna.

Obutoffaali obuyitibwa blast cells bukula okuva mu butoffaali buno obusibuka. Era ziyitibwa obutoffaali bwa "progenitor" oba "precursor". Kwe kugamba, ziba mutendera gwa "pre" nga obutoffaali obukuze mu bujjuvu tebunnakula. Obutafaananako katoffaali akasibuka, akatoffaali akakuba (blast cell) kasalibwawo dda okufuuka ekika ky’obutoffaali ekigere. Kiba ng’okugenda mu yunivasite n’osooka okusoma amasomo aga bulijjo, olwo n’ossa essira ku mulimu ogw’enjawulo.

Migaso ki egy’obutoffaali obuyitibwa blast cells eri omubiri gwaffe?

Obutoffaali obuyitibwa blast cell buba bwa ntandikwa yokka ey’okutondebwa kw’obutoffaali bw’omusaayi. Omubiri gwo buli kiseera gukola obutoffaali obupya obw’omusaayi (nga kw’otadde n’obutoffaali obuyitibwa blast cells) okudda mu kifo ky’obutoffaali obukadde. Enkola eno ey'okukola omusaayi eyitibwa hematopoiesis . Kino kisinga kubaawo mu busimu bwo obw'amagumba .

Munda mu busimu bwo obw'amagumba, waliwo akatoffaali aka bulijjo akayitibwa "hematopoietic stem cell" (HSC). Kino kivaamu ebika bibiri ebikulu eby’obutoffaali obubwatuka:

• Myeloblast: Ekika kino eky’obutoffaali obukuba omukka kiva muObutoffaali obumyufu, obutoffaali obweru (okugeza, granulocytes, monocytes, neutrophils, basophils, ne eosinophils), ne platelets bikolebwa.
• Lymphoblast: Ekika kino eky’obutoffaali obuyitibwa blast cell kivaamu lymphocytes, ekika ky’obutoffaali obweru.

Obutoffaali bw’omusaayi obukuze mu bujjuvu buva mu busimu bw’amagumba ne buyita mu musaayi gwo. Kyokka obutoffaali obuyitibwa blast cells obukyakula buba mu busimu bwo obw’amagumba so si mu musaayi gwo. Eno y’ensonga lwaki lipoota ya laabu eraga obutoffaali obuyitibwa blast cells mu musaayi gwo eyinza okuba ekizibu.

Lwaki obutoffaali buno obuyitibwa blast cells bweyongera? Waliwo ekikyamu?

Singa lipoota ya laabu eraga nti olina obutoffaali obuyitibwa blast cells bungi mu magumba go oba mu musaayi, kiyinza okuba akabonero ka kookolo w’omusaayi, gamba nga leukemia. Naddala singa obutoffaali bulabika nga tebuli bwa bulijjo nga butunuuliddwa mu microscope. Mu budde obwabulijjo, ebitundu 5% byokka ku butoffaali bwonna obw’omusaayi mu busimu bwo bwe bulina okuba obutoffaali bwa blast. Si kirungi kuba na butoffaali bwa blast mu musaayi gwo n’akatono.

Waliwo ensonga enkulu eziwerako lwaki obutoffaali obukuba (blast cells) bweyongera:

• Obulwadde bwa leukemia obw’amaanyi (AML) .
• Obulwadde bwa myelodysplastic syndrome (MDS) .
• Obulwadde bw’omusaayi obutawona (CML) .
• Obulwadde bw’omusaayi obuyitibwa Acute lymphoblastic leukemia (ALL) .
• Embeera ezimu ezitali za kookolo n’obujjanjabi

Ka tulabe buli kimu ku bino mu bujjuvu katono.

Ka tuyige ku bulwadde bwa Acute Myeloid Leukemia (AML) .

Ebiseera ebisinga, abasawo bwe boogera ku butoffaali obuyitibwa blast cells, baba boogera ku acute myeloid leukemia (AML) . AML kika kya kookolo ekikambwe ennyo era asaasaana mangu nnyo. N’olwekyo kikulu nnyo okuzuula obulwadde buno n’okutandika obujjanjabi amangu ddala nga bwe kisoboka. Okukebera obutoffaali buno obuyitibwa blast cells ngeri nkulu ey’okuzuula obulwadde buno nga bukyali.

Mu AML, obutoffaali obuyitibwa blast cells obutali bwa bulijjo bukuŋŋaanyizibwa mu busimu bwo obw’amagumba ne bukulukuta ne bufuluma mu musaayi gwo. Ebisinga ku bino kika kya butoffaali obuyitibwa myeloblasts. Bino byetegefu okufuuka obutoffaali obweru (granulocytes) nga tebunnafuuka butoffaali bwa kookolo.

Olw’okuba obutoffaali buno obuyitibwa blast cells tebukuze era tebuli bwa bulijjo, tebukola mulimu gwonna gwa mugaso eri mubiri. Mu kifo ky’ekyo, zitwala ekifo kinene nnyo mu busimu bw’amagumba ne kiremesa omubiri gwo okukola obutoffaali obupya obulungi obw’omusaayi bwe gwetaaga. Awatali butoffaali bwa musaayi bukola bulungi era nga bukuze, omubiri gwo tegusobola kukola bulungi.

Bw’oba ​​olina obutoffaali obukuba ebitundu 20% oba okusingawo mu busimu bw’amagumba oba mu musaayi gwo, kabonero ka AML.

Obulwadde bwa Myelodysplastic Syndrome (MDS) kye ki?

Obulwadde bwa kookolo obuyitibwa Myelodysplastic syndrome (MDS) nakyo kika kya kookolo w’omusaayi. Ekibaawo wano nti obutoffaali obuyitibwa blast cells tebukula ne bufuuka butoffaali bwa musaayi obwa bulijjo. Ebiseera ebisinga, obutoffaali buno obw’okubwatuka bufa nga tebunnakula bulungi. Newankubadde nga waliwo obutoffaali obuyitibwa blast cells bungi nnyo, bwe wabaawo obutoffaali obukulu obusobola okukola omulimu gwabwo butono nnyo, ebizibu ng’okukendeera kw’omusaayi bisobola okubaawo. Ekirala, oyinza okufuna yinfekisoni enfunda eziwera (olw’obutoffaali obweru obutono) n’okuvaamu omusaayi oba okunyiga amangu (olw’obutoffaali obutono).

Bwoba olina obutoffaali obukuba wakati wa 5% ne 20% mu magumba go, kabonero ka mbeera eyitibwa `MDS.` Abantu nga 30% abalina `MDS` ku nkomerero bajja kufuna `AML.`

Ka tulabe n’obulwadde bwa Chronic Myeloid Leukemia (CML).

Chronic myeloid leukemia (CML) kookolo w’omusaayi ow’ekiseera ekiwanvu (chronic). Era kireeta omuwendo gw’obutoffaali obuyitibwa blast cells mu busimu bw’amagumba oba mu musaayi okweyongera. Abasawo bagabanya obuzibu bw’embeera eno okusinziira ku ddaala ly’obutoffaali bwo obw’okubwatuka:

• Chronic Phase CML: Obutoffaali obutawera 10% mu musaayi gwo oba mu busimu bw’amagumba buba butoffaali bwa blast.
• Accelerated Phase CML: Obutoffaali obuli wakati wa 10% ne 19% mu musaayi gwo buba butoffaali bwa blast.
• Blast Phase CML (blast crisis): Obutoffaali obusoba mu 20% mu musaayi gwo butoffaali bwa blast. Kino kifaananako ne AML.

Obulwadde bwa Acute Lymphoblastic Leukemia (ALL) kye ki?

Acute lymphoblastic leukemia (ALL) kye kika kya kookolo ekisinga okubeera mu baana. Mu BONNA, obusigo bw’amagumba bukola obutoffaali obutali bwa bulijjo (obw’obulwadde bwa kookolo) obuyitibwa lymphoblasts. Obutoffaali buno obutali bwa bulijjo bwawukana mangu ne bukola kkopi nnyingi. Kino kizibuwalira obusigo bw’amagumba okukola obutoffaali obwa bulijjo omubiri gwo bwe gwetaaga.

Mu BONNA, waakiri ebitundu 20% ku butoffaali bw’omusaayi mu busimu bwo obw’amagumba buba butoffaali bwa blast. Abantu abasinga obungi abazuuliddwa n’obulwadde buno (nga 90%) nabo balina obutoffaali obuyitibwa blast cells mu musaayi gwabwe.

Obutoffaali obuyitibwa blast cells busobola okweyongera olw’ensonga endala okuggyako kookolo?

Yee, kino kikulu nnyo. Tolowooza nti kookolo kiva ku lipoota ya laabu eraga obutoffaali bwa blast obw’amaanyi. Embeera n’ebivaako ebimu ebitali bya kookolo nabyo bisobola okuleeta okweyongera kw’obutoffaali obukuba omukka okumala akaseera. Eby’okulabirako mulimu:

• Yinfekisoni ez’amaanyi: Singa omubiri gwo gufuna obulwadde obw’amaanyi, gamba nga yinfekisoni ey’amaanyi (sepsis), obutoffaali obuyitibwa blast cells busobola okuyingira mu musaayi.
• Obujjanjabi bwa granulocyte-colony stimulating factor (G-CSF): Obutoffaali obubwatuka buyinza okuba nga bukyalabibwa mu musaayi oluvannyuma lw’okufuna ekika ky’empiso eyitibwa G-CSF. Empiso zino zisitula obusigo bw’amagumba go okukola obutoffaali obweru obusingawo okukukuuma obutakwatibwa yinfekisoni. Bino biyinza okwetaagisa bw’oba ​​ofuna eddagala lya ddagala oba ng’olina obutoffaali obweru obutono (neutropenia).
• Okusimbuliza obutoffaali obusibuka mu mubiri: Bw’oba ​​obadde okyusiddwa obutoffaali obusibuka mu mubiri ng’obujjanjabi bw’embeera y’obujjanjabi, oyinza n’okweyongera mu butoffaali obuyitibwa blast cells. Okusimbuliza obutoffaali obusibuka mu mubiri kiyinza okwetaagisa olw’embeera ng’obuzibu mu musaayi, kookolo, oba endwadde z’abaserikale b’omubiri omubiri gwo mwe gutasobola kukola butoffaali bwa musaayi obwa bulijjo.

Naye ekikulu kiri nti, obutafaananako butoffaali bwa blast obukwatagana ne kookolo, obutoffaali obubwatuka obulabibwa mu mbeera zino butera okulabika nga bulamu bulungi wansi wa microscope. Era zisobola okukula ne zifuuka obutoffaali bw’omusaayi obwa bulijjo. Ekiseera bwe kigenda kiyitawo, omuwendo guno gukendeera.

Okebera otya mu butuufu omutindo gw’obutoffaali obukuba (blast cells)? Ebigezo ebyo bye biruwa?

Waliwo okukebera okuwerako okulaga emiwendo gy’obutoffaali obutulisa:

• Peripheral blood smear (PBS): Okukebera kuno kulaga nti mu musaayi gwo mulimu obutoffaali obuyitibwa blast cells. Mu PBS, omukugu mu by’endwadde atunuulira sampuli y’omusaayi gwo ng’akozesa microscope okulaba oba obutoffaali obukuba omukka bungi nnyo oba bulabika nga tebuli bwa bulijjo.
• Okukebera obusigo bw’amagumba: Okukebera mu laabu okukolebwa oluvannyuma lw’okukeberebwa oba okusiba obusimu bw’amagumba kuyinza okuzuula obutoffaali obuyitibwa blast cells mu busimu bw’amagumba. Bino biyinza okuli okukebera nga flow cytometry, immunohistochemistry, oba fluorescence in situ hybridization (FISH) okunoonya enkyukakyuka mu buzaale mu butoffaali .
• Oyinza n’okukwetaagisa okuba n’omuwendo gw’omusaayi omujjuvu (CBC) ng’olina enjawulo okukebera obutoffaali bwo obumyufu n’obweru n’obutoffaali obukola omusaayi, kubanga omuwendo gw’obutoffaali obulamu guyinza okukendeera ng’omuwendo gw’obutoffaali obukuba omusaayi gweyongera.

Abasawo balowooza ku bivudde mu kukebera n’ensonga ez’enjawulo nga tebannazuula mbeera nga leukemia. Tebasalawo binene nga basinziira ku kigezo kimu kyokka.

N’ekisembayo, ebintu ebitonotono by’olina okujjukira

Ekisinga obukulu si kutya ng'olaba ekigambo "blasts" mu lipoota yo eya laabu.Kituufu okubeera n’obutoffaali obuyitibwa blast cells mu musaayi gwo kiyinza okuba akabonero k’obulwadde obw’amaanyi. Naye kisinziira ku bulamu bwo. Oluusi, okweyongera kw’obutoffaali obukuba (blast cells) kuba kwa kaseera buseera. Omuwendo gukendeera okumala ekiseera. Oluusi, kiyinza okuba akabonero k’ekintu eky’amaanyi ennyo, gamba ng’obulwadde bwa acute leukemia. Omusawo wo yekka y’asobola okunnyonnyola ddala ebyavaamu bye bitegeeza eri obulamu bwo. Kale, bw’oba ​​olina ekibuuzo kyonna, tolwawo kubuuza musawo wo.
