Bangi ku ffe tutya ekigambo "kookolo." Kintu kya bulijjo nnyo. Naye leero, olw’okuba ssaayansi w’obusawo akulaakulana nnyo, kisoboka okubeera nga bulijjo n’ebika bya kookolo ebimu. Leero, tugenda kwogera ku kimu ku bika bya kookolo w’omusaayi ng’ebyo. Oyo ye CML, ekitegeeza Chronic Myeloid Leukemia. Erinnya lino oyinza okuba nga wawulira oluvannyuma lw’okukeberebwa omusaayi bulijjo. Kale, katukyogereko mu bujjuvu awatali kutya.
Okay, kale CML eno kye ki?
Mu ngeri ennyangu, CML kookolo w’omusaayi gwaffe. Kitandikira mu busimu bw’amagumba obuli munda mu magumba gaffe. Obusigo bw’amagumba bulinga ekkolero erikola ebika by’obutoffaali omubiri gwaffe bye gwetaaga oguyitibwa obutoffaali obumyufu, obutoffaali obweru, n’obutoffaali obuyitibwa platelets. Mu CML, waliwo ekikyamu ku butoffaali obusibuka obuyitibwa myeloid stem cells mu butoffaali buno obw’obusigo bw’amagumba, ne butandika okwawukana n’okukula mu ngeri etafugibwa.
Kino era kiyitibwa `chronic myelogenous leukemia` oba `chronic granulocytic leukemia`.
Naye amawulire agasinga obukulu era agasinga obulungi wano gali nti olw’obujjanjabi obw’omulembe obw’ennaku zino, abantu abasinga obungi abalina CML basobola okuwangaala obulamu obwa bulijjo . Kino kitegeeza nti mu kifo ky’okubeera obulwadde obutta, bufuuse obulwadde obutawona era nga busobola okufugibwa n’eddagala.
CML eno egenda mu maaso mangu etya?
Ekigambo "eky'olubeerera" kitegeeza "eky'ekiseera ekiwanvu." Era bwekityo obulwadde buno bwebuli. CML bulwadde bwa bulijjo nnyo. Oluusi kiyinza okumala emyaka nga tekirina bubonero bwonna. Abantu bangi bakizuula nti bakifuna mu butanwa, bwe bakeberebwa omusaayi olw’ensonga endala ne balaga obutali bwa bulijjo mu muwendo gw’obutoffaali bwabwe.
Naye singa tebujjanjabwa, embeera eno eyinza okufuuka obulamu obw’akabi mu myaka esatu oba ena. N’olwekyo kikulu nnyo okuzuula obulwadde n’okutandika obujjanjabi nga bukyali.
Bubonero ki omuntu alina CML bw’ayinza okufuna?
Ebiseera ebisinga, tewayinza kubaawo bubonero bunene mu biseera ebisooka. Kyokka waliwo obubonero obumu obutera okulabika ng’obudde bugenda buyitawo. Bino bitera okuba ebintu bye tulowooza nti bya bulijjo ne tutafaayo.
| Obubonero | Ennyinyonnyola ennyangu |
|---|---|
| Okukoowa buli kiseera n’okunafuwa | Bulijjo okuwulira ng’okooye, ne bw’oba weebaka bulungi ate nga tokola mulimu gwonna. |
| Obuzibu mu kussa (Dyspnea) . | Okugwa ng’otambula olugendo olutono oba ng’olinnya amadaala. |
| Omusujja awatali nsonga | Okuwulira ebbugumu nga tolina bulwadde bulala bwonna. |
| Entuuyo z’ekiro | Okutuuyana ekiro okutuuka ku ssa ng’ebitambaala bifuuse amazzi, wadde ng’ekisenge kinnyogoga. |
| Okugejja awatali nsonga | Okugejja mu bwangu nga tolina diet oba dduyiro. |
| Okuzimba oba obutabeera bulungi mu kitundu kya waggulu ekya kkono eky’olubuto | Kino kiva ku kuzimba kw’enkwaso, esangibwa mu kitundu kino eky’olubuto. |
| Okuwulira ng’ojjudde ne bw’omala okulya katono | Ensigo ezimba esobola okusika ku lubuto, ekikuleetera okuwulira ng’ojjudde ne bw’olya akatono. |
Lwaki CML ekulaakulana? Kiba kya nsikirano?
Ekibuuzo kino kintu abantu bangi kye balina. Ekisinga obukulu okutegeera wano kiri nti CML si bulwadde bwa nsikirano . Kino kitegeeza nti abaana tebakikulaakulanya lwa kuba nti bazadde baabwe baalina. Era si kintu ekisikira.
CML ebaawo nga enkyukakyuka (mutation) ebaddewo mu buzaale bw’obutoffaali bwaffe, kwe kugamba obutoffaali obusibuka mu busimu bw’amagumba, mu bulamu bwaffe. Kino kiyitibwa `enkyukakyuka efunibwa`.
Okay, kati ka tulabe engeri kino gye kikola. Mu ngeri ennyangu, kiri bwe kiti:
1. Enkyukakyuka ebaawo mu buzaale bw’obutoffaali bwaffe obusibuka, era obuzaale obupya, obwongezeddwaako obuyitibwa `BCR-ABL` ne butondebwa.
2. This new gene gives new instructions to stem cells to make an unusual form of an enzyme called `tyrosine kinase`.
3. Lowooza ku enzymes zino nga zifaanana nga switch "on" ne "off" ezikoleeza ettaala. Bino bye bifuga enjawulo y’obutoffaali.
4. Naye enziyiza eyo eya `tyrosine kinase` ekoleddwa mu ngeri etaali ya bulijjo terina switch ya "off". Bulijjo kiba "ku".
5. Olw'okuba tewali switch "off", obutoffaali obusibuka mu busimu bw'amagumba bweyongera okufuna obubonero okugabanya, okugabanya, n'okukula mu ngeri etafugibwa.
6. N’ekyavaamu, omuwendo omunene ogw’obutoffaali obweru obutakuze (era obuyitibwa `blasts`) butandika okutondebwa.
7. Ekiseera bwe kigenda kiyitawo, obutoffaali buno obutali bwa bulijjo bujjuza obusimu bw’amagumba. Olwo obusigo bw’amagumba bufiirwa obusobozi bwabwo okukola obutoffaali obumyufu, obutoffaali obweru, n’obutoffaali obuyitibwa platelets obulamu. N’ekyavaamu, obubonero obwogeddwako waggulu butandika okulabika.
Obulabe n’ebizibu ebiyinza okuva mu kino
Ensonga ezireeta akabi
Ekintu kyokka ekimanyiddwa eky'obulabe eri okulwala CML kwe kukwatibwa emisinde egy'amaanyi ennyo . Kyokka kino tekitera kubaawo nnyo. Emiwendo gy’obusannyalazo gye tusanga mu bulamu obwa bulijjo (okugeza, okuva mu kukeberebwa X-ray) tegigireeta.
Ebizibu ebiyinza okuvaamu
CML esobola okuleeta ebizibu bibiri ebikulu:
- Anemia: Okukendeera mu kukola obutoffaali obumyufu obulungi, ekikendeeza ku bungi bwa oxygen omubiri gwe gwetaaga, ekivaako obukoowu n’okufuuka omumyufu.
- Splenomegaly: Obutoffaali bw’omusaayi bungi obutali bwa bulijjo bukuŋŋaanyizibwa mu nnywanto, ekigireetera okuzimba. Kino kiyinza okuvaako olubuto obutabeera bulungi n’okuwulira ng’ajjudde ne bw’olya akatono.
Okugatta ku ekyo, okunoonyereza okumu kulaga nti abantu abalina CML bayinza okuba n’obulabe obweyongedde katono obw’okufuna ebika bya kookolo ebirala (kookolo owookubiri).
Abasawo bazuula batya obulwadde bwa CML?
Kino omusawo ayinza okukiteebereza ng’akebera omusaayi mu ngeri ennyangu. Kyokka okukakasa obulwadde buno, kyetaagisa okukeberebwa okw’enjawulo okunoonya enkyukakyuka mu buzaale.
| Ekigezo | Kiki ky’olaba mu kino? |
|---|---|
| Okubala Omusaayi mu bujjuvu (CBC) . | Bakebera okulaba oba obutoffaali obweru bungi nnyo oba obutoffaali obumyufu butono nnyo. |
| Okusinda obusigo bw’amagumba/Okukebera obusimu bw’amagumba | Sampuli entono ey’obusimu bw’amagumba bagitwala ne bagikeberebwa okulaba oba enkyukakyuka mu buzaale eyitibwa `BCR-ABL` eriwo. |
| CT Scan (Ekipimo kya kompyuta) . | Kebera olabe oba kookolo asaasaanidde mu bitundu by’omubiri ebirala (e.g. ennywanto, ekibumba). |
| Okukebera mu ngeri ya Ultrasound | Okukebera kuno kukozesebwa okulaba oba enseke zisinga ku za bulijjo. |
Mitendera ki egya CML?
Okwawukanako ne kookolo omulala, CML teteekebwa mu kibinja kya "emitendera 1, 2, 3, 4." Wabula, kisengekebwa nga "emitendera." Kino kisalibwawo omuwendo gw’obutoffaali obweru obutakuze (`blasts`) mu musaayi n’obusigo bw’amagumba.
- Omutendera ogutawona: Guno gwe mutendera ogusooka. Mu musaayi n’obusigo bw’amagumba mulimu obutoffaali obutono obutawera 10% obwa `blasts`. Abantu 80-90% abazuuliddwa nga balina CML bali mu mutendera guno. Abantu bano bayinza okuba n’obubonero oba obutaba na bubonero.
- Omutendera ogw’amangu: Mu mutendera guno, omuwendo gw’obutoffaali bwa `blasts` gweyongera okutuuka wakati wa 10% ne 19%. Obubonero butandika okweyoleka.
- Blast Phase oba Blast Crisis: Guno gwe mutendera ogusinga okuba ogw’amaanyi era oguyinza okutta omuntu. Omuwendo gw'obutoffaali bwa `blasts` gweyongera ebitundu 20% oba okusingawo. Obubonero ng’okukoowa ennyo, omusujja, n’okugejja bifuuka bya maanyi.
- Resistant CML: Lino lye linnya eriweebwa CML etaddamu bujjanjabi oba eddamu oluvannyuma lw’okujjanjabwa.
Bujjanjabi ki obuweebwa CML?
Wano amawulire amalungi agakwata ku CML we gayingira.Leero, waliwo obujjanjabi obukola ennyo ku bulwadde buno.
Obujjanjabi obukulu bwe kiraasi y’eddagala eriyitibwa Tyrosine Kinase Inhibitors (TKIs) . Lino ddagala erimira ng’empeke.
Jjukira enzyme etali ya bulijjo gye twayogeddeko emabegako ekola nga switch ya "on"? Ekyo eddagala lino kye ligenderera. TKIs kye zikola ziyimiriza enzyme eyo etalina "off" switch okukola. Bakizibira. Olwo obutoffaali obwo obwa CML obugabanya mu ngeri etafugibwa tebufuna kabonero ka kugabanya, era oluvannyuma lw’akaseera obutoffaali obwo bufa.
TKI zino zikoze enjawulo nnene mu bulamu bw’abalwadde ba CML. Eddagala lino nga terinnajja, abantu nga 20% bokka abazuuliddwa nga balina CML be bawangaala okumala emyaka 5. Naye leero, nga tulina TKIs, ebitundu ebyo ku buli kikumi byeyongedde okutuuka ku bitundu ebisukka mu 90%.
Eddagala lino litera okumira obulamu bwonna. Ebimu ku bika bya TKI ebikozesebwa ennyo bye bino:
- Imatinib
- Dasatinib, eddagala eriweweeza ku bulwadde
- Eddagala lya Nilotinib
- Obulwadde bwa Bosutinib
- Eddagala lya Ponatinib
TKIs zirina ebizibu ebivaamu?
Yee, okufaananako n’eddagala lyonna, wayinza okubaawo ebizibu ebivaamu. Naye ebiseera ebisinga zisobola okuddukanyizibwa. Ebisinga okumanyibwa bye bino:
- Okulumwa olubuto
- Obukoowu
- Embiro
- Okuyiringisibwa kw’ebinywa
- Okuzimba
- Oluusi, ebintu ng’ekibumba okwonooneka n’obutoffaali obutono mu musaayi bisobola okubaawo.
Omusawo ajja kwogera naawe ku bizibu bino era akuyambe okubiddukanya.
CML ewonyezebwa ddala?
Mu kiseera kino, engeri yokka ey'oku "wonya" CML eri n'okusimbuliza obutoffaali obusibuka mu mubiri (allogeneic stem cell transplant ) . Kino kizingiramu okukyusa obutoffaali obusibuka mu muntu omulamu obulungi okubuyingiza mu mulwadde. Wabula buno bujjanjabi buzibu nnyo era bwa bulabe. N’olwekyo, kitera okukolebwa ku balwadde bokka abataddamu ku TKIs.
Okubeera ne CML kiri kitya era endowooza eri etya?
CML bw’egenda mu kusonyiyibwa n’obujjanjabi, tokyalina bubonero era tewali bubonero bwa bulwadde buno busobola kuzuulibwa ku kukeberebwa. Kino kitegeeza nti osobola okubeera n’obulamu obwa bulijjo. Naye ojja kwetaaga okugenda mu maaso n’okumira eddagala okusobola okufuga obulwadde buno. Era ojja kwetaaga okulaba omusawo buli kiseera okukeberebwa omusaayi okukebera obujjanjabi bwo bwe bukola obulungi.
Okusonyiyibwa awatali bujjanjabi (TFR) .
Eno y’enkulaakulana esembyeyo era esinga okusuubiza mu bujjanjabi bwa CML. Kino kitegeeza nti abalwadde abamu abamaze ebbanga nga bamira eddagala lya TKI era ng’obulwadde bwabwe bufugibwa bulungi nnyo kati basobola okulekera awo okumira eddagala lino nga balabirirwa omusawo waabwe. Ne bwe bamaze okuyimiriza eddagala lino, obulwadde tebudda. Naye kino tekisoboka eri buli muntu. Olina okutuukiriza ebisaanyizo ebimu okugifuna.
Ekisinga obukulu, tolekera awo kumira ddagala lyo olw’ensonga yonna nga toyogedde na musawo wo. Ekyo kiyinza okuba eky’akabi ennyo.
Ebibuuzo ebikulu by’olina okubuuza omusawo wo
Bw’okizuula nti olina CML, kya bulijjo okuba n’ebibuuzo bingi mu birowoozo byo. Totya, buuza omusawo wo ku bintu bino.
- Nnina mutendera ki ogwa CML?
- Bujjanjabi ki bwe nnina?
- Nnawulira ntya mu kiseera ky’obujjanjabi? Biki ebivaamu?
- Nsobola okugenda mu maaso n’omulimu gwange nga nfuna obujjanjabi?
- Mirundi emeka gye nneetaaga okwekebeza omusaayi okulaba oba obujjanjabi buno bugenda bulungi?
- Emikisa ki egy’obulwadde bwange okugenda mu kusonyiyibwa?
- Okusimbuliza obutoffaali obusibuka mu mubiri (stem cell transplant) kusaanira embeera yange?
- Ani gwe nsobola okwogera naye ku kuddukanya ssente z’obujjanjabi?
Obubaka Obutwala Awaka
- CML kookolo w’omusaayi akula mpola. Si kya nsikirano.
- Enzijanjaba z’ennaku zino ezigendereddwamu, eziyitibwa TKIs, zikola nnyo, zisobozesa abantu bangi abalina CML okubeera obulamu obwa bulijjo, obuwanvu.
- Bw’omala okuzuulibwa nti olina obulwadde, tosattira era ogoberere ddala ebiragiro by’omusawo.
- Kikulu nnyo okumira eddagala mu budde n’okugenda mu malwaliro okwekebejjebwa mu budde.
- Toyimiriza oba okukyusa obujjanjabi nga tolina lukusa lwa musawo.
