Oboolyawo tewali kisinga kumenya mutima okusinga okulaba maama, taata, jjajja oba kojja waffe omukadde nga buli kimu beerabira mpolampola. Okutandika okuva ku kwerabira ebintu ebitonotono okutuuka ku nkomerero obutajjukira kye tuli oba abaana baffe kye bali, obulwadde bwa Alzheimer mbeera ddala etufuula ffenna obutaba na buyambi ng’amaka. Kale, watya singa akasana akatono ak’omusana kalabika wakati mu kire ekiddugavu bwe kiti? Watya singa wabaawo amawulire agakwata ku ddagala eppya eriyinza okukendeeza ku kukula kw’obulwadde bwa Alzheimer? Leero tugenda kwogera ku kunoonyereza okupya okuleese essuubi eryo.
Donanemab kye ki? Kikola kitya?
Mu ngeri ennyangu, Donanemab ddagala ddene erinoonyereza erikolebwa okujjanjaba obulwadde bwa Alzheimer. Ekolebwa kkampuni y’eddagala eya Eli Lilly.
Kati, ekisinga okuvaako obulwadde bwa Alzheimer’s kirowoozebwa nti kwe kukuŋŋaanyizibwa kwa puloteyina ey’obulabe eyitibwa amyloid plaques mu bwongo. Okufaananako obusagwa obukola mu payipu zaffe ez’amazzi, obutoffaali buno bukuŋŋaanyizibwa wakati w’obutoffaali bw’obusimu mu bwongo ne butaataaganya emirimu gyabwo. Ekiseera bwe kigenda kiyitawo, kino kye kireeta obubonero ng’okubulwa okujjukira n’okukaluubirirwa okulowooza.
Eddagala lya Donanemab litunuulira nnyo ebifo bino ebiterekeddwa ebiyitibwa amyloid plaques. Eddagala lino bwe liweebwa omubiri, ligenda mu bwongo, ne litegeera ebirungo bino ebiterekeddwamu ebirungo ebiyamba omubiri ebitayagala, ne litandika okubiggyamu. Kino kikola ng'obujjanjabi bw'obutoffaali obuziyiza endwadde . Omusingi gwa ssaayansi emabega wa kino kwe kuba nti bw’oyonja obwongo mu ngeri eno, busobola okukendeeza ku kukula kw’obulwadde buno.
Ebyavudde mu kunoonyereza kuno bituuse bulungi nnyo ne kiba nti Eli Lilly yeetegekera okusaba ekitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala ekya FDA okukkiriza eddagala lino okukozesebwa abantu bonna.
Ebyavudde mu kunoonyereza okwewuunyisa ebizuuliddwa mu kunoonyereza kuno
Kino si kunoonyereza kwonna kwokka. Kino kigezo kya randomized, double-blind, ekifugibwa placebo . Kwe kugamba, abalwadde baawulwamu ebibinja bibiri, era ekibinja ekimu ne kiweebwa eddagala ettuufu, ate ekibinja ekirala ne kiweebwa eddagala ery’ekicupuli eritaliiko kirungo kikola (placebo). Naye omulwadde oba ttiimu ejjanjaba tebamanyi ani afuna ddagala lino. Enkola eno etusobozesa okupima obulungi obw’amazima obw’eddagala lino awatali kusosola.
Kale katutunuulire ebimu ku bivudde mu kunoonyereza kuno. Bino biraga enjawulo eno gye kiyinza okuleeta mu bulamu bw’abalwadde ba Alzheimer.
| Ebisumuluzo ebizuuliddwa | Ennyonyola y’ebyavaamu |
|---|---|
| Obubonero obutagenda bweyongera | Ebitundu 47% ku abo abamira eddagala lya donanemab tebaalaga kweyongera mu bubonero oluvannyuma lw’omwaka mulamba, bw’ogeraageranya n’abo abamira eddagala lya placebo 29% bokka. |
| Okukendeeza ku bulwadde buno | Bw’ogeraageranya n’abo abamira eddagala lya placebo, abamira Donanemab baakendedde ebitundu 35% mu kigero ky’obulwadde obweyongera. |
| Obusobozi okukola emirimu egya buli lunaku | Obusobozi bw'okukola emirimu gya buli lunaku nga okwambala n'okukola caayi ku bubwo bukendedde ebitundu 40% . Kino kiwummuza nnyo omulwadde n’ab’omu maka. |
| Obulabe bw’okukulaakulana okutuuka ku mutendera oguddako ogw’obulwadde | Abo abaamira Donanemab baali bakendedde ebitundu 39% ku bulabe bw’okugenda mu mutendera oguddako, ogw’amaanyi ennyo ogw’obulwadde buno. |
| Emiwendo gya amyloid mu bwongo | Ne mu myezi 6 gyokka nga batandise obujjanjabi, emiwendo gya amyloid plaques mu bwongo bw’abalwadde gikendedde nnyo. |
Okunoonyereza kuno kwakwata ku balwadde abali mu ntandikwa y’obulwadde buno. Era zaasengekeddwa okusinziira ku miwendo gyazo egya tau , puloteyina endala epima obuzibu bw’obulwadde buno. Ekyewuunyisa, n’abalwadde abalina obulwadde obusingako n’abalina eddagala lya tau eringi balabye nti abamu baganyulwa mu ddagala lino.
Tumanyi n’ebizibu ebivaamu.
Nga bwe kiri ku ddagala lyonna, waliwo ebizibu ebimu ebigambibwa nti bivaamu. Nga twogera ku ssuubi, twetaaga okuba abeesimbu ku kabi kano.
Ekizibu ekikulu ekirabibwa ku ddagala lino y’embeera eyitibwa ARIA (Amyloid-Related Imaging Abnormalities) . Mu ngeri ennyangu, kino kizimba kya kaseera buseera oba mini brain bleed mu bwongo. Kiteeberezebwa nti kikwatagana n’enkola y’okuggyawo amyloid.
- 24% ku abo abaamira eddagala lya DonanemabOkuzimba kw’obwongo kubaddewo, naye abantu 6% bokka be balaze obubonero.
- Okuvaamu omusaayi omutono kwaliwo mu balwadde nga 31% (kino nakyo kyaliwo mu 14% ku abo abamira eddagala lya placebo).
Ekisinga obulungi kiri nti embeera zino ezisinga eza ARIA teziba nnyo oba za kigero era zisobola okuwona oba okutebenkera n’obujjanjabi obutuufu.
Kyokka, n’ensonga eno tetusaanidde kwerabira. Eky’ennaku, abantu basatu abafa nga beekuusa ku mbeera eno eya ARIA nabo bategeezeddwa mu kunoonyereza kuno. Kino kitulaga engeri okulabirirwa kw’abasawo okumpi ennyo gye kwekulu ennyo ng’okozesa eddagala ery’amaanyi bwe lityo.
Abakugu boogera ki ku nsonga eno?
Abakugu mu by’obusimu okwetoloola ensi yonna basanyufu nnyo olw’ebivudde mu kunoonyereza kuno. Abamu bagamba nti, "Kati tuyingidde mu mulembe gw'okujjanjaba obulwadde bwa Alzheimer."
"Oluvannyuma lw'emyaka mingi nga tunoonyereza nga tetufunye buwanguzi, kati tufuna ebivuddemu ebikwatagana ebiraga nti okuggyawo amyloid kiyinza okukyusa enkola y'obulwadde buno," omukugu omu bwe yategeezezza.
Ekirala eky’enjawulo ku ddagala lino y’engeri gye liweebwamu. Okunoonyereza kulaga nti puloteyina ey’obulabe eya amyloid mu bwongo bw’emala okukendeezebwa okutuuka ku ddaala eritali limu, eddagala lino liyinza okuyimirizibwa . Obujjanjabi buyimiriziddwa mu balwadde 52% mu mwaka gumu ate mu 72% mu myezi 18. Kino kiringa "okuleetera okusonyiyibwa" obulwadde n'okubwetegereza nga tolina bujjanjabi. Kino kiyinza okuba enkizo ennene eri abalwadde nga kwotadde n’ensimbi ezisaasaanyizibwa mu bujjanjabi.
Naye abakugu abamu bakyali beegendereza katono. Bagamba nti, "Ebyavuddemu bino birabika bulungi nnyo, naye twetaaga okulaba ebikwata ku nsonga eno mu bujjuvu. Waliwo ebizibu ebinene ebivaamu, era twetaaga okumanya ebisingawo ku ngeri gye bikosaamu abalwadde."
Obubaka Obutwala Awaka
- Donanemab si ddagala eriwonya bulwadde bwa Alzheimer, naye ddagala erikendeeza nnyo ku kukula kw’obulwadde buno, era liwa essuubi ddene eri ebiseera eby’omu maaso.
- Kino kikola nga kiggyawo obuwuka obw’obulabe obwa amyloid obukuŋŋaanyizibwa mu bwongo.
- Kino kiyamba abalwadde naddala mu ntandikwa y’obulwadde buno okukuuma okujjukira kwabwe n’obusobozi okukola emirimu gya buli lunaku okumala ebbanga eddene.
- Okuzimba ku bwongo n’okuvaamu omusaayi omutono (ARIA) .Waliwo akabi k’ebizibu eby’amaanyi, n’olwekyo bw’oba osazeewo okukola obujjanjabi buno, olina okubukola ng’olabirirwa nnyo abasawo.
- Eddagala lino likyali mu mutendera gw’okunoonyereza. Kijja kutwala ekiseera nga tekinnatuuka kukozesebwa mu Sri Lanka. N’olwekyo, singa omuntu mu maka go alaga obubonero bw’obulwadde bwa Alzheimer, ekisinga obulungi kwe kulaba omusawo alina ebisaanyizo amangu ddala n’ofuna amagezi.
