Tulina okumanya PTLD (Post-Transplant Lymphoproliferative Disorders) oluvannyuma lw’okusimbuliza ebitundu by’omubiri?

Ggwe oba omuntu gw’omanyi oboolyawo yalongoosebwa ekintu ekinene ekitaasa obulamu, gamba ng’okukyusa ebitundu by’omubiri. Oba okukyusa obutoffaali obusibuka mu mubiri. Oluvannyuma lw’ebintu bino, wabaawo ebizibu ebitali bimu, ebitali bisuubirwa. Ekimu ku bizibu ng’ebyo ye PTLD, oba Post-Transplant Lymphoproliferative Disorders. Okuva bwe kiri nti kino kiyinza okuba eky’amaanyi katono, ka tukyogereko mu ngeri ennyangu gy’osobola okutegeera.

Ddala PTLD kye ki?

Mu ngeri ennyangu, PTLD kizibu ekiyinza okutta omuntu ekiyinza okubaawo oluvannyuma lw’okusimbuliza ebitundu by’omubiri oba okusimbuliza obutoffaali obusibuka mu mubiri (allogeneic stem cell transplant). Ekibaawo wano kiri nti ekika ky’obutoffaali obweru mu mubiri gwaffe, ekiyitibwa lymphocytes, kyeyawukana mangu ne kikula nga tekifugibwa.

Embeera eno eyitibwa PTLD mu butuufu kika kya lymphoma . Lymphoma kika kya kookolo akula mu nkola yaffe ey’amazzi. Embeera eno ebaawo ng’obutoffaali obweru bufuuse kookolo ne bukula mangu nga tebufa.

PTLD etera okuva ku kawuka ka Epstein-Barr Virus (EBV) . Kano kawuka ffenna ke tulina mu mibiri gyaffe. Waliwo ebika bya PTLD eby’enjawulo, era engeri gye bikosaamu omuntu eyinza okwawukana. Ekirungi nti abasawo basobola okukijjanjaba. Kyokka oluusi embeera eno esobola okuddamu.

Bika ki ebikulu ebya PTLD?

Abasawo bagabanyaamu PTLD mu bika bina ebikulu okusinziira ku ngeri obutoffaali bwa lymphoma gye bulabika wansi wa microscope:

• Early Lesion: Abantu bano bafuna obubonero obufaananako n’obwo obulabibwa n’akawuka ka Epstein-Barr virus (EBV).
• Polymorphic PTLD: Wano, obutoffaali bwa lymphoma butabulwa n’ebika ebirala eby’obutoffaali obweru, gamba nga lymphocytes eza bulijjo n’obutoffaali bwa plasma.
• Monomorphic PTLD: Kino kye kika kya PTLD ekisinga okubeerawo . Obutoffaali bwa lymphoma wano bufaananako n'obwo obusangibwa mu bika ebirala ebya lymphoma, nga ``Non-Hodgkin Lymphomas''. Okugeza, ``Obulwadde bwa Diffuse Large B-cell Lymphoma'' oba ``Burkitt Lymphoma''.
• Classic Hodgkin Lymphoma - ekika kya PTLD: Kino kye kika kya PTLD ekitali kya bulijjo .

Embeera eno eyitibwa PTLD ya bulijjo etya?

Nga bwe kyayogeddwako emabegako, PTLD mbeera etali ya bulijjo nnyo . Ekyo kitegeeza nti tekituuka ku buli muntu. Mu ngeri enkambwe, abantu nga 2 ku 100 ababadde bakyusiddwa obutoffaali obusibuka (`(2%)`) bajja kufuna PTLD. Abantu abakyusiddwa ebitundu by’omubiri batera okukwatibwa PTLD. Naye ekyo nakyo kyawukana okusinziira ku kitundu ky’omubiri ekisimbibwa.

Lowooza ku kino, so nga abantu nga basatu ku buli 100 abakyusiddwa ekibumba (`(3%)`) bafuna embeera eno, abakugu bagamba nti abantu nga kkumi ku 100 abakyusiddwa amawuggwe (`(10%)`) bayinza okufuna embeera eno. Kale, tewali kye yeeraliikirira, kino si kintu ekituuka ku bantu abasinga obungi.

Bubonero ki obuyinza okuva mu PTLD?

Abantu abamu bayinza obutaba na bubonero bwonna mu kusooka. Obubonero bwa PTLD busobola okulabika ekiseera kyonna, okuva ku myezi mitono okutuuka ku myaka egiwerako oluvannyuma lw’okusimbibwa. Singa obubonero bulabika, buyinza okuli:

• Okuwulira nga okooye nnyo (`Fatigue`) : Okuwulira nga tolina bulamu bwokka.
• Omusujja awatali nsonga .
• Emmere tewooma .
• Okugejja nga tosuubira .
• Okutuuyana ekisusse ekiro (`Okutuuyana ekiro`) .
• Ensigo ezizimba : Ziwulira ng’ebizimba mu bulago ne mu nnyindo.

Lwaki PTLD eno ebaawo? Biki ebivaako?

Kino kiwanvuye katono okukitegeera. PTLD ebaawo kubanga akawuka akamanyiddwa ennyo kakozesa omukisa gw'obunafu mu baserikale baffe abaserikale b'omubiri .

Kuba akafaananyi ng’oteekateeka okusimbuliza obutoffaali obusibuka mu mubiri. Ekyo nga tekinnatuuka, ojja kuweebwa eddagala eriweweeza ku bulwadde bwa kookolo okutta obutoffaali bwa kookolo obuli mu busimu bw’amagumba go. Kino kiyitibwa okulongoosa (conditioning). Kino kinafuya obusobozi bw’abaserikale b’omubiri okukukuuma endwadde. Okusingira ddala, okulongoosa kukendeeza ku mirimu gy’obutoffaali bwa T (T-cells) obubadde bukwatibwa EBV ne buddamu obutakola.

Olwo oluvannyuma lw’okusimbuliza obutoffaali obusibuka oba ekitundu ky’omubiri, omubiri gwo guweebwa eddagala eriweweeza ku busimu bw’omubiri okugutangira okugaana ekintu ekipya. Wadde eddagala lino likuuma ekitundu oba obutoffaali obupya, naye era banafuya abaserikale baffe bennyini, ekigifuula ennyangu eri abalumbaganyi ab’amawanga amalala nga akawuka.

Mu PTLD, ekirungo ekikulu eky’akawuka ye kawuka ka Epstein-Barr (EBV) . EBV ebadde ekwatagana ne PTLD ekula mu mwaka gumu oba ebiri oluvannyuma lw’okusimbuliza obutoffaali obusibuka oba ebitundu by’omubiri. Kyokka, ekituufu ekivaako PTLD ejja nga wayise emyaka oluvannyuma lw’okusimbibwa tekinnamanyika. Abakugu era banoonyereza oba akawuka nga cytomegalovirus (CMV) oba adenovirus (Adenovirus) kayinza okukola kinene.

Okusinziira ku bakugu, abantu baffe nga 90% babadde bakwatibwa EBV mu kiseera ekimu mu buto oba mu myaka gyabwe egy’obutiini. Oyinza okuba n’akawuka kano nga tolina bubonero bwonna, era oyinza n’obutamanya. Akawuka ka EBV kasiiga obutoffaali bwaffe obwa B ne kasigala nga "kasula" munda mu mubiri, kwe kugamba, mu mbeera ya ``Latent'', awatali kuleeta buzibu bwonna. (Oyinza n’okuba ofunye akawuka kano okuva ku muntu agaba obuyambi.)

Olw’okuba omira eddagala eryo eriziyiza obusimu bw’omubiri, abaserikale b’omubiri bo tebasobola kukuuma EBV eyo esula wansi. Olwo, obutoffaali bwa B obulina EBV butandika okweyawulamu n’okweyongera amangu. Ekyo kye kivaako PTLD.

Ani ali mu bulabe obw’amaanyi obw’okukwatibwa PTLD?

Obulabe bwo obw’okufuna PTLD buyinza okweyongera olw’ensonga zino wammanga:

• Okubeera n’akawuka ka Epstein-Barr (EBV) mu mubiri gwo oba mu mubiri gw’omuntu eyakuwa ekitundu/obutoffaali (`(Donor)`).
• Okuba nga ofunye obujjanjabi (`Pre-transplant conditioning') ekikendeeza ku nkola eya bulijjo ey'obutoffaali bwo obwa T nga tonnasimbibwa.
• Okumira eddagala eriweweeza ku busimu bw’omubiri okutangira omubiri gwo okugaana ekitundu oba obutoffaali obupya.
• Okubeera n’enjawulo mu buzaale obumu (`(Genes)`) ekyongera ku bulabe bw’okufuna PTLD.

Abasawo bazuula batya embeera eno eyitibwa PTLD?

Abasawo bajja kusooka kukeberebwa mubiri era batunuulire n’obwegendereza ebyafaayo by’obujjanjabi bwo. Okugatta ku ekyo, ebiseera ebisinga bajja kukola ebigezo bino wammanga:

• Okubala Omusaayi Okujjuvu (`Okubala Omusaayi Okujjuvu - CBC`) .
• Ekipande ekikwata ku nkyukakyuka mu mubiri .
• Omutindo gwa lactate dehydrogenase (LDH) .
• Okwekenenya omusulo , omuli n’omuwendo gwa asidi wa uric.
• Okukebera okuzuula obutoffaali obuziyiza endwadde obukolebwa mu mubiri okulwanyisa akawuka ka EBV .
• CT scan (`Ekifaananyi kya kompyuta - CT scan`) .
• Okukebera kwa MRI (Magnetic Resonance Imaging - MRI) .
• PET scan (`Positron Emission Tomography - Okukebera kwa PET`) .
• Okukebera obusigo bw'amagumba .

Ebigezo bino bye bisobozesa abasawo okuzuula ddala oba PTLD eriwo oba nedda, era bwe kiba bwe kityo, bw’efaanana.

Bujjanjabi ki obuweebwa PTLD?

Abasawo batera okutandika nga bakendeeza ku ddagala eriweweeza ku busimu obuziyiza endwadde lye bamira . Oluusi kino kiyinza okuleeta enjawulo nnene. Ng’oggyeeko ekyo, waliwo obujjanjabi obulala nga:

• Chemotherapy : Eddagala eritta obutoffaali bwa kookolo.
• Radiation therapy : Okusaanyaawo obutoffaali bwa kookolo nga tukozesa emisinde egy’amaanyi amangi.
• Immunotherapy with monoclonal antibodies : Kino kizingiramu okukozesa obutoffaali obw’enjawulo (monoclonal antibodies) okulumba obutoffaali bwa kookolo.
• Okulongoosa : Kino tekitera kukolebwa. Okulongoosa kulowoozebwako singa PTLD ebeera mu kitundu era ng’esobola okuggyibwamu awatali bulabe. Okugeza, singa tonsils zikosebwa PTLD, tonsils ziyinza okuggyibwamu.

Waliwo kye tuyinza okukola okuziyiza PTLD okukula?

Mu butuufu tewali kye tuyinza kukola okuziyiza butereevu PTLD. Wabula abasawo n’abanoonyereza batunuulidde eddagala erimu eriyinza okukozesebwa nga tebannaba kusimbibwa na/oba oluvannyuma lw’okusimbuliza okukendeeza ku bulabe bwa PTLD. Kale, waliwo essuubi nti wajja kubaawo eby’okugonjoola ebirungi ku kino mu biseera eby’omu maaso.

Kiki ekibaawo singa ofuna PTLD? Kisobola okuwona?

Engeri gy’onooddamu PTLD eyinza okwawukana okusinziira ku muntu. Kisinziira ku bintu bingi.

Ng’ekyokulabirako, oluusi PTLD etereera ne bwe kiba nti abasawo bamala kukendeeza ku ddagala eriziyiza obusimu bw’omubiri.

Okunoonyereza okwakakolebwa kulaga nti wakati wa 60% ne 70% ku bantu abafuna obulwadde bwa lymphoma oluvannyuma lw’okusimbuliza ebitundu by’omubiri era ne bajjanjabwa n’obujjanjabi bw’obusimu obuziyiza endwadde n’eddagala eriweweeza ku bulwadde buno bafunye okukendeera oba okubula kw’obubonero (okusonyiyibwa) .

PTLD esobola okuwona? Yee, PTLD esobola okuwona ne `Immunotherapy` yokka oba nga egattibwa wamu ne `Chemotherapy`. Okunoonyereza kulaga nti abantu wakati wa 50% ne 60% abafuna obujjanjabi buno bawona ddala . Kale, kino kintu kya kubeera n’essuubi.

Bibuuzo ki ebikulu bye nnina okubuuza omusawo wange?

Bw’oba ​​olina PTLD, kirungi okubuuza omusawo wo ebibuuzo nga bino:

• Lwaki kino kyantuukako?
• PTLD ejjanjabwa etya?
• Singa nkendeeza ku ddagala lyange eriziyiza obusimu obuziyiza endwadde, omukisa guli gutya nti omubiri gwange gujja kugaana ekitundu/obutoffaali obupya?
• Singa obujjanjabi bwange buba buwanguzi, emikisa ki egy’embeera eno okuddamu?

Ng’oggyeeko ebibuuzo bino, totya kubuuza musawo kintu kyonna ky’olina mu birowoozo.

Ddi lwe nnina okulaba omusawo?

Bw’oba ​​olina PTLD, omusawo wo ajja kulondoola obulamu bwo okutwalira awamu obulungi . Bajja kunoonya obubonero obulaga nti embeera yo yeeyongera okwonooneka. Bw’oba ​​ojjanjabwa PTLD, omusawo ajja kukunnyonnyola enkyukakyuka ki z’oyitamu oba obubonero bwo bweyongera okusajjuka. Kikulu okutegeeza omusawo wo amangu ddala singa kino kibaawo.

N’ekisembayo, ebintu by’olina okujjukira

Okukyusa ebitundu by'omubiri n'okukyusa obutoffaali obusibuka mu mubiri oluusi bisobola okutaasa obulamu oba okwongera ku bulamu . Kyokka olw’okuba zino nkola za bujjanjabi nnene, ziyinza okujja n’akabi. PTLD kye kimu ku bizibu ng’ebyo ebitali bimu, naye ebiyinza okuba eby’amaanyi.

Bw’oba ​​nga oli muntu eyeesimbyewo okusimbuliza ekitundu ky’omubiri oba obutoffaali obusibuka mu mubiri, ttiimu yo ey’ebyobulamu ejja kwogera naawe ku bulabe bwo obw’okulwala PTLD , awamu n’ebintu ebirala bingi ebiyinza okuleeta akabi. Abasawo n’abanoonyereza banoonya engeri y’okukendeeza ku bulabe bw’okulwala PTLD. Ekisinga obukulu kwe kumanya kino n’okubuuza ttiimu yo ey’ebyobulamu ebibuuzo byonna by’oyinza okuba nabyo.
