Tumanyi engeri gye kizibu okubeera ne kookolo. Naye olw’okukulaakulana kwa ssaayansi w’obusawo, enkola z’okujjanjaba kookolo ziteredde nnyo leero. Mu kifo ky’obujjanjabi obw’eddagala oba obujjanjabi obw’amasannyalaze gokka nga bwe kyali edda, kati waliwo obujjanjabi obw’enjawulo obugenderera n’okulumba obutoffaali bwa kookolo bwokka. Eddagala eriziyiza PARP kika kya ddagala erireese essuubi eppya mu nsi y’okujjanjaba kookolo. Leero, kino tugenda kukyogerako mu ngeri ennyangu, mu ngeri gy’osobola okutegeera.
Mu ngeri ennyangu, bino PARP Inhibitors bye biruwa?
Kino okukitegeera, ka tusooke tulowooze ku butoffaali obuli mu mubiri gwaffe. Buli katoffaali mu mubiri gwaffe kalimu ekintu ekiyitibwa DNA. DNA eno eringa ‘master plan’ erimu ebiragiro byonna obutoffaali bye bwetaaga okukola. Oluusi DNA eno esobola okwonooneka. Bwe kyonoonese, omubiri gwaffe guba n’enkola ey’enjawulo okuguddaabiriza.
Ekimu ku bikulu mu nkola eno ey’okuddaabiriza ye puloteyina eyitibwa PARP. PARP kitegeeza Poly (ADP-ribose) polymerase. Wadde erinnya lino liwulikika nga lizibu, omulimu gwalyo mwangu: Singa wabaawo okumenya oba okumenya mu DNA, puloteyina ya PARP eyingira n’agiddaabiriza. Kino kyetaagisa nnyo eri obutoffaali obulamu.
Naye wuuno obuzibu. Obutoffaali bwa kookolo nabwo bukozesa puloteyina eno eya PARP mu ngeri eganyula. Obutoffaali bwa kookolo bwe bwawukana amangu, DNA yabwo eyonoonese. Olwo akatoffaali ka kookolo kakozesa ‘bass’ eno eya PARP okuddaabiriza DNA yaako, n’eyongera okukula, n’etandika okusaasaana mu mubiri gwonna.
Ebiziyiza PARP bikola nga biyimiriza ‘bass’ ya PARP okukola. Okubeera omutuufu, ziremesa puloteyina ya PARP okuddaabiriza DNA. Kino kiremesa akatoffaali ka kookolo okuddaabiriza DNA yaako, era okukkakkana ng’akatoffaali kafa.
Zino era ziyitibwa targeted therapies , kubanga eddagala lino litunuulira era ne lilumba obunafu bw’obutoffaali bwa kookolo okusinga obutoffaali obulamu obwa bulijjo.
Eddagala lino likozesebwa ku bika ki ebya kookolo?
Eddagala eriziyiza PARP litera okukozesebwa ku kookolo asinga okukula oba agenda mu bitundu ebirala. Kyokka teziweebwa ku kookolo yenna. Zisinga kukola ku kookolo akwatagana n’enkyukakyuka y’obuzaale eyeetongodde.
Enkolagana wakati w’obuzaale bwa BRCA n’ebiziyiza PARP
Waliwo obuzaale obukuuma mu mubiri gwaffe obuziyiza ebizimba bya kookolo okutondebwawo. Ekimu ku bikulu ye BRCA gene . Omu ku mirimu gy’obuzaale buno obwa BRCA kwe kuddaabiriza DNA eyonoonese. Kino kitegeeza nti waliwo enkola bbiri enkulu ez’okuddaabiriza DNA mu butoffaali bwaffe: emu ye PARP, ate endala ye BRCA.
Kati teebereza, omuntu azaalibwa n’enkyukakyuka mu buzaale bwa BRCA.Ekyo kitegeeza nti emu ku nkola ze ez’okuddaabiriza DNA ya nnafu dda. Olwo obutoffaali bwe obwa kookolo kumpi bwesigamye ddala ku nkola eyo eya PARP okuddaabiriza DNA.
Kale kiki ekibaawo nga tuwa omuntu nga oyo eddagala eriziyiza PARP? Ng’oggyeeko enkola ya BRCA eyamenyeka edda, tuyimiriza n’enkola ya PARP eyali ekola obulungi. Olwo akatoffaali ka kookolo tekalina ngeri yonna gye kayinza kuddaabiriza DNA yaako. Olw’okukuba kuno okwa ‘double hit’, akatoffaali ka kookolo kasaanawo mangu nnyo.
N’olwekyo, ebiziyiza PARP bujjanjabi bukola nnyo ku kookolo alina enkyukakyuka mu buzaale bwa BRCA.

Obujjanjabi buno buweebwa butya era bumala bbanga ki?
Ekimu ku birungi ebiri mu bujjanjabi buno kwe kuba nti tebulina kuweebwa ng’empiso. Ebiziyiza bino byonna ebya PARP bijja mu ngeri y’empeke oba kkapu. Zitera okulagirwa okumira omulundi gumu oba ebiri olunaku.
Oluusi okusinziira ku kika kya kookolo gw’olina, eddagala lino liyinza okuweebwa ng’obujjanjabi bwokka. Oba, kiyinza okuweebwa nga kigatta wamu n’obujjanjabi obulala, gamba ng’obujjanjabi obw’eddagala. Okugeza, omuntu bw’amala okuweebwa eddagala eriweweeza ku bulwadde bwa kookolo n’obutoffaali bwa kookolo obwonooneddwa, eddagala lino eriziyiza PARP litandikibwawo. Olwo, kimalawo ddala omukisa gw’obutoffaali bwa kookolo obwo obwonooneddwa okweddaabiriza.
Ebbanga ly’obujjanjabi lyawukana okusinziira ku muntu. Abamu eddagala lino liweebwa okumala ekiseera ekigere, gamba ng’emyaka ebiri oba esatu bukya ddagala liwedde. Ku balala, kigenda mu maaso okumala ebbanga lyonna eddagala lye likola, ekitegeeza nti kookolo aba afugibwa. Ekisinga okusalawo ku nsonga eno kwe kwogera n’omusawo wo n’opimira emigaso gy’obujjanjabi n’ebizibu ebiyinza okuvaamu.
Emigaso n’ebizibu ebiyinza okuva mu bujjanjabi buno
Ebiziyiza PARP biyinza obutawonya kookolo ddala. Wabula omugaso gwazo ogusinga obunene kwe kuba nti zongera "okuwangaala okutaliimu kukulaakulana." Mu ngeri ennyangu, eddagala lino liyamba okufuga kookolo n’okumukuuma ng’afuga okumala ebbanga eddene. Kino kitegeeza nti omulwadde alina obudde bungi okubeera obulamu obulungi ennyo nga obulwadde tebugenda kweyongera .
Okufaananako n’obujjanjabi bwonna obwa kookolo, bino bisobola okuvaako ebizibu naye si buli muntu nti abifuna.

Ddi lw’osaanidde okuyita omusawo mu bwangu?
Kikulu nnyo okubeera ng’okwatagana nnyo n’omusawo wo mu kiseera kyonna eky’obujjanjabi buno. Bw’ofuna obubonero bwonna obupya oba singa obubonero bwo obuliwo bweyongera, tegeeza omusawo mu bwangu. Ayinza okukyusakyusa mu ddoozi yo oba okukuwa eddagala eddala okuyamba ku bizibu ebiyinza okuvaamu ng’okuziyira.
Bw’ofuna obubonero buno wammanga, kuba essimu y’omusawo awatali kulwa :
- Obubonero obulaga nti omuntu alina yinfekisoni: omusujja, okuwunya, n’okukankana.
- Obubonero bw’obulwadde bw’amawuggwe (Pneumonitis): Okukaluubirirwa okussa, okuwulira ng’ekifuba kinywezeddwa oba okuwunya.
- Obubonero bw’omusaayi okuzimba: okuzimba amangu, okumyuuka, n’okulumwa ekigere, oba okulumwa mu kifuba okw’amangu n’okukaluubirirwa okussa.
Bw’ofuna obubonero buno obw’amaanyi, olina okuyita amangu omusawo wo oba okugenda mu ddwaaliro erikuli okumpi mu kitongole ky’abalwadde ab’amangu (ETU) .
Obubaka Obutwala Awaka
- Ebiziyiza PARP kika kya ‘targeted therapy’ ekiyimiriza obutoffaali bwa kookolo okuddaabiriza DNA yaabwe ne busaanyawo.
- Bino bikola nnyo naddala ku mbeera nga kookolo w’amabeere, enkwaso, n’enseke ezirina enkyukakyuka mu buzaale bwa BRCA.
- Obujjanjabi buno buweebwa ng’empeke oba kkapu era buyamba okufuga okukula kwa kookolo n’okwongera ku budde bw’osobola okubeera omulamu obulungi.
- Nga bwe kiri ku bujjanjabi obulala, ebizibu biyinza okubaawo, n’olwekyo kyetaagisa okukolagana obulungi n’omusawo wo mu kiseera kyonna eky’obujjanjabi.
- Omusawo wo ajja kuzuula oba obujjanjabi bwa PARP inhibitor bukusaanira, ng’alowooza ku mbeera yo ey’obujjanjabi, ebyava mu kukeberebwa kw’obuzaale, n’obulamu okutwalira awamu.
