Enkola eyasembyeyo ey’okukozesa obutoffaali bwo okulwanyisa kookolo (CAR T-cell Therapy)

Wali olowoozezza nti omubiri gwaffe gusobola okulwanyisa kookolo ku bwagwo? Mu butuufu, omubiri gwaffe gulina enkola ey’amagezi ennyo ey’okwekuuma eyitibwa abaserikale b’omubiri. Kirina ekitundu kyayo eky’enjawulo ekiyitibwa T-cells, nga zino ziringa abaserikale. Omulimu gwabwe kwe kunoonya n’okusaanyaawo obuwuka obugwira n’obutoffaali obukyusiddwa obuyingira mu mubiri. Naye oluusi, obutoffaali bwa kookolo buba bwa makubo nnyo. Zikweka obutoffaali buno obuyitibwa T cells, zibulimba ne zikula munda mu mubiri. Mu biseera ng'ebyo, tugenda kwogera ku bujjanjabi obupya, obw'ekitalo obuyamba obutoffaali bwaffe obwa T okutegeera n'okusaanyaawo obutoffaali bwa kookolo nga tubuwa "okutendekebwa okw'enjawulo."

Mu ngeri ennyangu, obujjanjabi bwa CAR T-cell kye ki?

Wadde ng’erinnya lino liyinza okuwulikika ng’ekizibu, endowooza yaayo nnyangu nnyo. Obujjanjabi bwa CAR T-cell kika kya bujjanjabi obuziyiza endwadde. Kizingiramu okutwala obumu ku butoffaali bwo obwa T n’okyusa obuzaale mu laboratory.

Lowooza ku butoffaali bwam obwa T ng’abaserikale ba poliisi. Obutoffaali bwa kookolo bulinga ababbi abeefudde. Ebiseera ebisinga, poliisi tesobola kutegeera babbi bano. Obujjanjabi bwa CAR T-cell bulinga okuwa abaserikale bo (T cells) endabirwamu ey’enjawulo. Endabirwamu eno eyitibwa ‘Chimeric Antigen Receptor’ (CAR) . Kikolebwa mu laabu ne kinywezebwa ku butoffaali bwa T.

Kati, endabirwamu eno ey’enjawulo bw’eteekebwako, obutoffaali bwa T busobola okutegeera obulungi obutoffaali obw’enjawulo (antigens) ku ngulu w’obutoffaali bwa kookolo. Obutoffaali bwa kookolo obwali bukwekeddwa edda kati bulabika bulungi. Olwo obutoffaali bwa T obufunye amaanyi gano amanene, bugenda butereevu okulumba obutoffaali bwa kookolo ne bubusaanyaawo. Obujjanjabi buno buyamba nnyo mu kuwonya ddala ebika bya kookolo ebimu mu musaayi n’okuyamba abalala okuwangaala nga balina kookolo.

Bujjanjabi buno bujjanjaba bika ki ebya kookolo w’omusaayi?

Mu kiseera kino, obujjanjabi bwa CAR T-cell bukozesebwa ku bika bya kookolo by’omusaayi ebimu byokka ebitazzeemu bujjanjabi bulala (nga chemotherapy) oba ebikomyewo oluvannyuma lw’okujjanjabwa. Okuva bwe kiri nti bukyali bujjanjabi bupya nnyo, tebuweebwa kookolo yenna.

Omulongooti wansi gulaga ebika bya kookolo obujjanjabi buno bwe bukkirizibwa mu kiseera kino.

Enkola eno ey’obujjanjabi ebaawo etya?

Enkola eno yonna ebaawo mu mitendera egiwerako. Kiba ng’okutendeka abajaasi okugenda mu lutalo n’oluvannyuma n’obazzaayo mu lutalo.

Omutendera 1: Okukung’aanya obutoffaali bwo obwa T

Ekisooka, omubiri gwo gwetaaga okukung’aanya obutoffaali obweru naddala obwa T. Kino kikolebwa nga bayita mu nkola eyitibwa leukapheresis . Kino kizingiramu okusindika omusaayi gwo ng’oyita mu kyuma, ekyawula obutoffaali obweru bwokka, n’ozzaawo omusaayi ogusigadde mu mubiri gwo. Kino kiringa okugaba omusaayi, naye ekitundu ky’omusaayi kyokka kye kiggyibwako ate ekisigadde ne kiddizibwa.

2. Omutendera: Sindika obutoffaali bwa T mu laabu obukyuse

Ekiddako, obutoffaali bwa T obukuggyibwako busindikibwa mu laabu ey’enjawulo. Eyo, bannassaayansi bakozesa enkola y’obuzaale okuyingiza CAR (Chimeric Antigen Receptor) gye twayogeddeko emabegako mu butoffaali bwa T. Olwo, obutoffaali buno obupya obwa CAR T obukola amaanyi amangi (super-powered CAR T cells) bukulizibwa mu laabu okutuusa lwe buba n’obukadde n’obukadde bwabwo. Enkola eno etwala wiiki ssatu ku mukaaga.Kiyinza okutwala ekiseera.

3. Omutendera: Okuteekateeka omubiri gwo

Okutuusa nga obutoffaali bwa CAR T bukoleddwa mu laabu, omusawo ayinza okukuwa obujjanjabi obulala (bridging therapy), gamba nga chemotherapy, okufuga kookolo wo.

Olwo, ng’ebula ennaku ntono obutoffaali bwa CAR T obupya obutondeddwawo bukuwe, ojja kuweebwa eddagala lya dose entono. Kiyitibwa eddagala erikendeeza ku lymphodepleting chemotherapy . Kino kikola nga kikendeeza ku butoffaali bw’abaserikale b’omubiri gwo obuliwo, ne kireetawo embeera ennungi obutoffaali obupya, obwa super CAR T-cells okukola.

4. Omutendera: Okuzza obutoffaali bwa super T mu mubiri

Guno gwe mukolo omukulu. Okufaananako n’okuwa eddagala ly’omunnyo, obutoffaali bwa CAR T obupya obutondeddwa bufukibwa mu mubiri gwo nga buyita mu musuwa (intravenous line - IV). Kino kitwala wakati w’eddakiika 5 ne 30. Obutoffaali buno bwe bumala okuyingira mu mubiri, butandika okweyongera ku bwabwo, nga bunoonya n’okusaanyaawo obutoffaali bwa kookolo. Olw'okuba obutoffaali buno bubeera mu mubiri okumala ebbanga eddene ne bulwanyisa kookolo, abamu obujjanjabi buno babuyita "ddagala ramu."

Kiki ekibaawo oluvannyuma lw’okujjanjabwa? Biki ebiyinza okuvaamu?

Olw’okuba buno bujjanjabi bwa maanyi nnyo, oluusi ebizibu eby’amaanyi bisobola okubaawo. N’olwekyo, ojja kuba olina okubeera mu ddwaaliro okumala wiiki nga emu okutuuka ku nnaku kkumi ng’omaze okujjanjabibwa. Abasawo ne ba nurse bajja kukulondoola nnyo.

Ebikulu Ebivaamu

Waliwo ebizibu bibiri ebikulu era ebisinga okuva mu bujjanjabi buno. Wadde nga bino biyinza okuba eby’akabi, ttiimu z’abasawo zirina ebyuma ebirungi okubijjanjaba.

Obujjanjabi buno buba buwanguzi butya?

Obujjanjabi bwa CAR T-cell buleese essuubi eppya eri abantu bangi abalwanyisa kookolo w’omusaayi naddala abo abatazzeemu bujjanjabi bulala.

• Okugeza, abaana abasoba mu 85% abaafuna obujjanjabi buno olw’obulwadde bwa childhood acute lymphoblastic leukemia (ALL) baasonyiyibwa ddala kookolo waabwe oluvannyuma lw’okujjanjabibwa. Era, 60% ku bo baali bakyali tebalina kookolo oluvannyuma lw’omwaka gumu oluvannyuma lw’okujjanjabwa.

Tekinologiya ono akyagenda mu maaso. Abanoonyereza okwetoloola ensi yonna buli kiseera bagezaako okulongoosa obujjanjabi buno, okukendeeza ku buzibu obuvaamu, n’okulaba oba busobola okukozesebwa ku bika bya kookolo ebirala.

Ddi lw’osaanidde okulaba omusawo?

Ebizibu ebiva mu bujjanjabi buno naddala Cytokine Release Syndrome n’obuzibu bw’obusimu, biyinza okuteeka obulamu mu matigga . N’olwekyo nga tonnava mu ddwaaliro, buuza omusawo obubonero bw’olina okwegendereza naddala.

Singa obubonero ng’omusujja, okusannyalala, okulumwa omutwe, n’okuziyira bisigalawo, kiyinza okuba akabonero k’embeera ey’amaanyi. Bwe kiba bwe kityo, kuba essimu y’omusawo wo mu bwangu oba genda mu kitongole ky’eddwaaliro eky’amangu (ETU).

Bw’oba ​​ggwe oba omuntu gw’omanyi alina kookolo w’omusaayi, yogerako n’omusawo wo oba obujjanjabi bwa CAR T-cell bukusaanira. Wadde ng’obujjanjabi buno si bwa buli muntu, buyinza okukyusa obulamu bw’omuntu omutuufu.
