Watya singa obutoffaali obupya bufuuka omulabe w’omubiri? Ennyinyonnyola ennyangu ku bulwadde bwa Graft vs. Host Disease (GvHD) oluvannyuma lw’okusimbuliza

Teebereza nga bakuweereddwa ekyuma ekikusimbuliza obutoffaali obusibuka mu mubiri okuva ku muntu omulamu obulungi ng’obujjanjabi bw’obulwadde nga leukemia. Kino kisuubirwa okuwonya embeera yo. Naye si bulijjo nnyo, obutoffaali buno obupya obwajja okukuyamba, omubiri gwo gubukyamusa nti "omulabe" ne gutandika okulumba obutoffaali bwo. Eyo y'embeera enzibu gye tuyita "Graft versus Host Disease" oba GvHD mu bufunze.

GvHD kye ki mu bigambo ebyangu?

Kino okusobola okukitegeera, tulina okumanya ebigambo bibiri. "Graft" kitegeeza ekintu ekisimbibwa, kwe kugamba, obutoffaali obusibuka obulungi obukuweebwa okuva ebweru. "Host" kitegeeza host, kwe kugamba, omubiri gwo ogufuna obutoffaali obwo. Kale "Graft versus Host" kitegeeza "graft okusinziira ku host."

Mu bujjuvu, ekika kino eky’okusimbuliza obutoffaali obusibuka, ekiyitibwa allogeneic transplant, kikolebwa okujjanjaba kookolo nga leukemia ne lymphoma, oba embeera z’okulemererwa kw’obusimu bw’amagumba nga aplastic anemia . Obutoffaali buno obusimbibwa bwe butandika omubiri gwo okukola obutoffaali obupya.

Naye, oluusi obutoffaali buno obupya tebutegeera butoffaali bwo. Balowooza nti balumbaganyi ba bagwira. Kale, zitandika okulumba ebitundu byo ebiramu, ng’olususu lwo, ekibumba, n’ebyenda. Ekyo GvHD ky’eri.

Waliwo ebika bya GvHD ebikulu bibiri:

GvHD esobola okwawulwamu ebika bibiri ebikulu. Edda kino kyagabanyizibwamu okusinziira ku kiseera obubonero we butandikira. Naye kati, abasawo bazuula ekika ekituufu nga batunuulira obubonero, ebyava mu kukeberebwa, n’ekiseera obubonero we butandikira.

• Acute GvHD (aGvHD): Kino kitera okubaawo mu nnaku 100 ezisooka oluvannyuma lw’okusimbuliza. Naye oluusi kiyinza okubaawo oluvannyuma. Ekika kino okusinga kikwata olususu lwo, enkola y’omu lubuto (ebyenda), n’ekibumba.
• Chronic GvHD (cGvHD): Ekika kino kiyinza okubaawo ekiseera kyonna oluvannyuma lw’okusimbuliza, naye kisinga kubeerawo mu myaka ebiri egisooka . Kiyinza okukwata ekitundu kyonna eky’omubiri omuli olususu, akamwa, ekibumba, amawuggwe, ebyenda, ebinywa, ennyondo n’ebitundu by’ekyama.

Omuntu eyasimbulizibwa asobola okufuna ekimu ku bika bino ebibiri, byombi, oba asobola okuba omulamu obulungi nga tewali na kimu ku byo.

Bubonero ki obwa GvHD?

Obubonero bwa GvHD buyinza okuva ku butono ennyo, okutuuka ku bwa kigero, okutuuka ku bwa maanyi, n’okutuuka n’okutta omuntu. Ka tulabe obubonero obukwatagana n’ebika bino ebibiri.

Lwaki GvHD eno ebaawo?

Kino kya ssaayansi katono, naye nja kukinnyonnyola mu ngeri ennyangu.

Mu budde obwabulijjo, obutoffaali bw’abaserikale b’omubiri gwaffe butukuuma obutakwatibwa ndwadde nga bulwanyisa ebirungo eby’amawanga amalala nga akawuka ne bakitiriya. Naye obutoffaali obwo tebulumba butoffaali bwaffe. Ensonga lwaki kino kiri bwe kityo eri nti waliwo puloteyina ey’enjawulo ku ngulu w’obutoffaali bwaffe bwonna. Kino kiyitibwa Human Leukocyte Antigens (HLA) .

Okuggyako abalongo abafaanagana, HLA ya buli muntu ya njawulo.

Bw’ofuna obutoffaali obusibuka mu musaayi, obutoffaali obupya obukolebwa mu butoffaali obwo buba ne HLA y’omuntu eyakuwaayo obutoffaali obwo. Singa HLA eyo ya njawulo nnyo ku HLA yo, obutoffaali obwo obupya butunuulira obutoffaali mu mubiri gwo ne bulowooza nti, "Ono mulumbaganyi, ID ye tekwatagana na yaffe." Awo obutoffaali obwo we butandikira okulumba omubiri gwo.

Olw’ensonga eno, abasawo bakebera n’obwegendereza HLA y’oyo agaba n’oyo amuwadde okukakasa nti bali kumpi nga bwe kisoboka nga tebannaba kukyusa. Naye okuggyako ng’obutoffaali buggiddwa mu balongo, bulijjo wabaawo akabi akatono ak’okulwala GvHD.

Ani ali mu bulabe obw’amaanyi obw’okulwala GvHD?

Ensonga esinga obukulu ey’akabi kwe butakwatagana bwa HLA, naye ensonga endala eziwerako nazo zisobola okukola kinene.

Ate era, bw’oba ​​wali dda okufuna Acute GvHD (aGvHD), oba mu bulabe bwa maanyi obw’okulwala Chronic GvHD (cGvHD).

Embeera eno ezuulibwa etya era n’ejjanjabibwa etya?

Okuzuula obulwadde

Omusawo wo ajja kuzuula GvHD ng’akola okukebera omubiri, okutunuulira obubonero bwo, n’okukebera omusaayi n’okukebera omubiri. Okukebera omubiri (biopsy) kizingiramu okukwata akatundu akatono ak’olususu oba ekitundu ekikoseddwa ne bakikebera nga bakozesa microscope. Olw’okuba obumu ku bubonero bwa GvHD obutawona bufaananako n’embeera endala, omusawo wo ajja kugaana embeera endala nga tannazuula GvHD.

Obujjanjabi

Okuziyiza GvHD oluvannyuma lw’okusimbuliza, ojja kuweebwa eddagala eriweweeza ku busimu bw’omubiri eriziyiza abaserikale b’omubiri. Eddagala lino likola nga likendeeza ku busobozi bw’obutoffaali obugwira okulumba omubiri gwo.

• Ku GvHD ey’amaanyi (aGvHD): Ebiseera ebisinga, eddagala eriyitibwa corticosteroids liweebwa ng’empeke, empiso oba ng’ekizigo ekisiigiddwa ku lususu. Singa bino tebifuga bulwadde buno, eddagala eddala nga Ruxolitinib (Jakafi®) oba okugezesebwa mu malwaliro liyinza okulowoozebwako.
• Ku Chronic GvHD (cGvHD): Eddagala eriziyiza obusimu obuziyiza endwadde okumala ebbanga eddene nalyo liweebwa ku kino. Singa embeera eno tefugibwa bino, eddagala nga Ruxolitinib (Jakafi®), Belumosudil (RezurockTM), Ibrutinib (Imbruvica®) oba obujjanjabi obw’enjawulo nga photopheresis buyinza okwetaagisa.

Ebizibu ebiva mu bujjanjabi

Enzijanjaba zino zinyigiriza abaserikale b’omubiri, ekikendeeza ku busobozi bw’omubiri gwo okulwanyisa yinfekisoni. Kino kyongera obulabe bw’okufuna yinfekisoni za ffene, bakitiriya n’akawuka. Omusawo wo era ajja kukuwa eddagala okuyamba okuziyiza yinfekisoni zino eziyinza okutta omuntu.

Ebikosa ebirala ebiyinza okubaawo olw’obulwadde bwa GvHD

GvHD eri mu kabi eri obulamu?

Yee, GvHD eyinza okuteeka obulamu mu matigga. Okusingira ddala GvHD etali ya bulijjo y’esinga okufa oluvannyuma lw’okusimbuliza obutoffaali obusibuka, okuggyako obulwadde obusookerwako. Eno y’ensonga lwaki kikulu okukubaganya ebirowoozo n’omusawo wo ku bulabe obuliwo nga tonnafuna bujjanjabi bwonna.

Waliwo omugaso gwonna oguva mu GvHD?

Ekyewuunyisa, yee. GvHD erina emigaso egimu. Obutoffaali buno obupya obw’abaserikale b’omubiri obulumba obutoffaali bwo obulamu nabwo bunoonya ne busaanyaawo obutoffaali bwa kookolo bwonna obuyinza okusigala mu mubiri gwo. Kino kiyitibwa "ekikolwa kya graft-versus-tumor effect." N’olwekyo, okunoonyereza kulaga nti abalwadde abafuna GvHD tebatera kuddamu kufuna kookolo waabwe.

Ebintu by’osobola okukola olw’obukuumi bwo

Omusawo ajja kukunnyonnyola engeri gy’osaanidde okwerabirira ng’omaze okusimbuliza. Weegendereze naddala ku bintu bino bw’oba ​​oli mu bulabe bw’okulwala GvHD.

• Weekuume okuva ku musana: Omusana guyinza okwonoona GvHD. N’olwekyo yambala essaati ez’emikono emiwanvu n’empale empanvu ng’ofuluma ebweru. Kozesa eddagala eriziyiza omusana nga lirina waakiri SPF 50.
• Obuyonjo mu kamwa: Senya amannyo go bulungi okukendeeza ku bulabe bw’okulwala ennyindo.
• Emmere n’ebyokunywa: Weewale emmere erimu ebirungo, ebizigo, n’emmere eyinza okuvaako amabwa mu kamwa.
• Weekuume ku buwuka: Okuva bwe kiri nti abaserikale b’omubiri banafuye, weewale ebifo ebisasaana endwadde n’ebifo ebijjudde abantu. Bulijjo emikono gikuume nga miyonjo.

Ddi lwe nnina okulaba omusawo?

Kikulu okutegeeza omusawo mu bwangu singa olaba enkyukakyuka yonna mu mubiri gwo naddala obubonero obulaga nti olina yinfekisoni oba omusujja gwa diguli 38 (100.4 Fahrenheit) oba okusingawo. Yinfekisoni zisobola okufuuka ez’amaanyi amangu ng’omira eddagala eriziyiza abaserikale b’omubiri.

Omusawo ajja kukulondoola buli kiseera ng’omaze okusimbuliza okutunuulira ebizibu nga GvHD. Singa obubonero bubaawo, bajja kukyusa eddagala lyo oba okukuwandiikira eppya. Kikulu nnyo okumira eddagala lyonna eriragiddwa nga bwe liragiddwa n’okugoberera ebiragiro by’omusawo.
