Wali okirabye ng’omusulo gwo guddugavu katono, mpozzi n’okuvaamu omusaayi, ku makya? Olwanagana n’okuwulira ng’okooye buli kiseera, ng’owulira ng’oli muddugavu? Bino biyinza okuba obubonero bw’obulwadde obutatera kulabika mu musaayi abantu bangi bwe batawulirangako obuyitibwa PNH, oba Paroxysmal Nocturnal Hemoglobinuria. Totya nga owulira erinnya lino. Ka twogere ku buli kimu mu ngeri ennyangu era mu ngeri entegeerekeka.
Ddala PNH kye ki?
Mu ngeri ennyangu, PNH bwe buba abaserikale baffe bennyini bwe balumba mu bukyamu ne basaanyaawo obutoffaali bwaffe obw’omusaayi obumyufu obulungi. Teebereza, ekigenda mu maaso wano kiringa eggye eriteekeddwa okukuuma eggwanga, nga lilumba abantu b’eggwanga eryo.
Kino kiri bwe kityo kubanga waliwo enkyukakyuka mu buzaale mu bumu ku butoffaali obuli mu busimu bwaffe obw’amagumba. N’ekyavaamu, obutoffaali obumyufu obukolebwa obusimu obwo buba bunafu katono. Obutoffaali buno obunafu busobola bulungi okutegeerwa n’okusaanawo abaserikale b’omubiri gwaffe.
- Okusaanyaawo obutoffaali obumyufu: Mu ngeri y’obusawo, okumenya kuno okw’obutoffaali obumyufu kuyitibwa hemolysis .
- Enkyukakyuka mu langi y’omusulo: Hemoglobin ye puloteyina esangibwa mu butoffaali obumyufu ng’etambuza omukka gwa oxygen. Obutoffaali bwe bumenyeka, hemoglobin eno efuluma mu musaayi, n’esengejebwa ensigo, n’efulumizibwa mu musulo. Kino kiyitibwa hemoglobinuria . Eno y’ensonga lwaki omusulo gulabika nga gwa langi enzirugavu, kitaka oba omusaayi. Kino kitera okusinga okweyoleka mu musulo gw’oku makya.
Naye kimanye nti obubonero bwa PNH si bwe bumu eri buli muntu. Abantu abamu bayinza obutalaba nkyukakyuka yonna mu langi y’omusulo n’akatono.
Ekizibu ekirala eky'amaanyi ekiva mu bulwadde buno kwe kwongera obulabe bw'okuzimba omusaayi . Ebimu ku bizimba bino biyinza okutta omuntu. Ekirala, obulwadde buno tebusobola kukwata butoffaali bumyufu bwokka, wabula n’obutoffaali obweru obulwanyisa obuwuka n’obutoffaali obukola omusaayi obukomya okuvaamu omusaayi.
Bujjanjabi ki obw’obulwadde bwa PNH?
Obujjanjabi bwa PNH businziira ku bubonero bwo n’obuzibu bw’embeera yo. Omusawo wo ajja kuteesa naawe obujjanjabi ki obusinga okukuyamba. Omulongooti wansi gulaga ezimu ku bujjanjabi obukulu obuliwo mu kiseera kino.
| Enkola y’obujjanjabi | Mu ngeri ennyangu, kiki ekibaawo? |
|---|---|
| Obujjanjabi bwa androgen | Zino kika kya busimu bw’omusajja. Zisitula obusimu bw’amagumba n’okwongera okukola obutoffaali obumyufu. Ziyamba okukendeeza ku kukendeera kw’omusaayi. |
| Eddagala eriziyiza okuzimba omusaayi | Zitangira okuzimba omusaayi mu misuwa. Bino bifunibwa ng’empiso oba empeke. |
| Okuteekebwamu omusaayi | Obutoffaali obumyufu oba obutoffaali obuyitibwa platelet bwe buba wansi nnyo, obutaba na buzibu buno busasulwa okuteekebwa omusaayi ebweru. |
| Okukyusa obusigo bw’amagumba | Eno y’engeri yokka ey’okuwonya ddala PNH. Naye kya bulabe nnyo. N’olwekyo, ekozesebwa ku balwadde abasinga okuba ab’amaanyi bokka. |
| Ebiziyiza Ebijjuza (Complement Inhibitors). | Zitunuulira ekitundu ky’abaserikale b’omubiri ekisaanyaawo obutoffaali obumyufu ne ziyimiriza enkola eyo. Soliris ne Ultomiris bye bika by’eddagala lino. |
| Ensonga ezireeta okukula | Ayamba okwongera okukola obutoffaali obumyufu oba obweru nga busitula obusimu bw’amagumba. |
| Eddagala eddala | Omusawo era awandiika asidi wa folic, eddagala eriweweeza ku kyuma, eddagala eriweweeza ku bulwadde bwa steroid, n’eddagala eriweweeza ku busimu bw’omubiri nga bwe kyetaagisa. |
Kale ono Empaveli kye ki?
Empaveli ddagala ddene era erikola ennyo erya complement inhibitor erikozesebwa okujjanjaba PNH.
Lowooza ku baserikale baffe abaserikale b’omubiri ng’olujegere lwa puloteyina ezikwatagana. Ekitundu ekimu eky’olujegere luno kiyitibwa `Ensengekera y’okujjuliza`. Mu PNH, enkola eno ekola ekisusse era n’esaanyaawo obutoffaali obumyufu.
Eddagala erikadde (e.g. eculizumab) lyagenderera ekifo mu lujegere luno ekiyitibwa C5. Baakomya okusaanawo kwokka munda mu misuwa (intravascular hemolysis).
Wabula eddagala lino eppya eriyitibwa Empaveli, litunuulidde ekifo ekyasooka, ekiyitibwa C3. Ekirungi ekiri mu kino kiri nti kifuga okwonooneka munda mu misuwa, wamu n’okwonooneka munda mu bitundu by’omubiri ng’ekibumba n’ennywanto (extravascular hemolysis).
N’olwekyo, Empaveli eyinza okuba ey’omugaso naddala eri abalwadde abatannawona mu bujjuvu okuva ku ddagala lye baakozesa emabega era nga bakyagenda mu maaso n’okubulwa omusaayi.
Okozesa otya Empaveli?
Empaveli ddagala ly’osobola okukozesa awaka.
- Enkola: Eno empiso ya wansi w’olususu .
- Emirundi: Ebiseera ebisinga giweebwa emirundi ebiri mu wiiki .
- Omuwendo: Omusawo ayinza okutereeza ddoozi yo ng’akebera omutindo gw’ekirungo ekiyitibwa `Lactate Dehydrogenase (LDH)` mu musaayi gwo. Emiwendo gya LDH gipima obungi bw’obutoffaali obumyufu obumenyekamenyeka.
- Engeri y’okukozesaamu: Waliwo engeri bbiri ez’okukozesaamu kino. Ekimu kwe kukozesa ppampu entono etuusa eddagala mu mubiri mu ddakiika 30-60. Endala nkola ya mpiso ey’omulundi gumu ng’esiigibwa mu lubuto.
Tofaayo, omusawo wo oba nnansi omutendeke ajja kusooka kukuyigiriza engeri y’okukozesaamu kino.
Ebintu by’olina okumanya ku bulungibwansi n’obukuumi bw’eddagala lino
Obuwanguzi bwa Empaveli bukakasiddwa mu kunoonyereza kubiri okunene, PEGASUS ne PRINCE.
Mu ngeri ennyangu, mu kunoonyereza kwombi, abalwadde abamira Empaveli baalina emiwendo gya hemoglobin egya waggulu nnyo okusinga abo abaamira obujjanjabi obulala. Era baateekebwamu omusaayi mutono nnyo.
Ebizibu ebivaamu n’obukuumi
Ebikulu ebizibu ebirabibwa ku Empaveli bye bino:
- Obulumi, okumyuuka oba okuzimba mu kifo we baamukuba empiso: Kino kya bulijjo. Oyinza okufuna obuweerero ng’osiiga ice pack oba okuginyiga mu mazzi agabuguma.
- Okwongera ku bulabe bw’okukwatibwa yinfekisoni: Olw’okuba eddagala lino linyigiriza ekitundu ky’abaserikale b’omubiri, waliwo akabi ak’okukwatibwa endwadde ezimu eza bakitiriya (naddala obuwuka obusibiddwa).
Okukendeeza ku bulabe buno, omusawo ajja kukuwa okugema kwonna kwe weetaaga nga tonnatandika kumira Empaveli. Era olina okukuuma Patient Safety Card ng’omira eddagala n’okumala emyezi 2 ng’omaze okulimira. Kino kijja kuyamba abantu abakujjanjaba okumanya nti omira eddagala lino singa wabaawo embeera ey’amangu.
Enteekateeka ya Empaveli REMS kye ki?
Kino kigambo kizibu katono, naye mu ngeri ennyangu, kitegeeza pulogulaamu ey’enjawulo ey’obukuumi . Olw’obulabe bw’okukwatibwa eddagala nga Empaveli, enteekateeka ng’ezo ziteekebwa mu nkola ebitongole bya gavumenti.
Wansi w'enteekateeka eno eya `REMS (Risk Evaluation and Mitigation Strategy)`:
1. Omusawo akuwa eddagala lyo alina okuwandiisibwa mu pulogulaamu eno.
2. Edduuka ly’eddagala erikuwa eddagala lino nalyo lirina okukakasibwa ku kino.
3. Omusawo, olina okuba ng’omanyi bulungi akabi akali mu ddagala lino n’obubonero bw’obulwadde (omusujja, okulumwa omubiri, okulumwa omutwe ennyo).
Kino kikukakasa nti omanyi bulungi emigaso n’akabi akali mu ddagala lino era ng’olikozesa bulungi.
Obubaka Obutwala Awaka
- PNH bulwadde obutatera kulabika naye nga busobola okuddukanyizibwa ng’abaserikale b’omubiri bo bennyini basaanyaawo obutoffaali obumyufu.
- Empaveli ddagala lya maanyi nnyo, eppya erijjanjaba PNH erikomya okusaanyaawo obutoffaali bw’omusaayi.
- Eddagala lino liyinza okuleeta obuwuka, n’olwekyo kakasa nti ofuna amasasi omusawo g’akuwa. Weegendereze obubonero bwonna obulaga nti olina obulwadde.
- Empaveli eweebwa wansi w’enkola ey’enjawulo ey’okukola (REMS). Bulijjo kaadi y’obukuumi bw’omulwadde gy’ofuna kuuma naawe.
- Bw’oba olina ekibuuzo kyonna ku mbeera yo oba obujjanjabi bwo, nsaba oyogere n’omusawo wo awatali kulonzalonza.
