Icyo Avacincaptad-pegol ari cyo: Ibyo ikoreshwa, urugero rwa dose, ingaruka zayo n'ibindi

Avacincaptad-pegol ni umuti mushya wagenewe kuvura atrophy ya géographique, uburyo buhanitse bwa macular degeneration (AMD) iterwa n'imyaka. Ubu buvuzi bushya bukora bugamije proteyine ya komplementi mu jisho ryawe zituma imbere yawe igenda igabanuka.

Niba wowe cyangwa umuntu ukunda yaranzwe na atrophy ya géographique, birashoboka ko wumva uhangayitse n'amagambo y'ubuvuzi n'uburyo bwo kuvura. Uyu muti ugaragaza intambwe ikomeye mu kuvura indwara yari ifite uburyo bwo kuvura butagira byinshi.

Avacincaptad-pegol ni iki?

Avacincaptad-pegol ni umuti uterwa mu nshinge ugomba gushyirwa mu itsinda ry'imiti yitwa complement inhibitors. Yagenewe cyane gukoma mu nkokora imbere ya atrophy ya géographique, ari ryo terambere rya AMD yuma ituma umuntu atakaza imbere burundu.

Uyu muti ukora ubugamije kubuza proteyine zimwe na zimwe mu mikorere y'umubiri wawe y'ubudahangarwa zibasira mu buryo butari bwo selile nzima mu mboni yawe. Bitekereze nk'ugushyira feri ku mikorere y'umubiri w'ubudahangarwa yarenze urugero yangiza imbere yawe. Ubu buryo bugamije bufasha kubungabunga selile zifata urumuri mu macula yawe, igice cy'ijisho ryawe gishinzwe imbere ryiza, ryo hagati.

Uyu muti uterwa n'umuganga w'amaso yawe mu jisho ryawe hakoreshejwe urushinge ruto cyane. Nubwo bishobora gutera impungenge, iki gikorwa gikorerwa mu buryo bwera hamwe na anesthesia yo mu gace kugira ngo bigabanye kutagira umunezero.

Avacincaptad-pegol ikoreshwa mu kuvura iki?

Avacincaptad-pegol yemerejwe by'umwihariko kuvura atrophy ya géographique iterwa na macular degeneration iterwa n'imyaka. Iyi ndwara ifata macula, ikarema ahantu hatabona mu imbere yawe ryo hagati bigenda byaguka uko igihe kigenda.

Atrofiya ya geografiya ibaho iyo selile za retinal pigment epithelium (RPE) zipfuye, bigatuma ahantu h'ijisho ryawe hatabasha gukora neza. Utwo duce twapfuye tugaragara nk'ahantu h'umwijima cyangwa hatagaragara mu iyerekwa ryawe, bigatuma bigorana gusoma, gutwara imodoka, cyangwa kumenya mu maso.

Uyu muti ufatwa nk'ubuvuzi bukomeye ku rugero ruciriritse bwa AMD. Niwo ugamije kurusha imiti imwe na imwe ya sisitemu ariko bisaba inshinge za buri gihe kugira ngo ugire akamaro. Igice cya

Ntabwo bisaba kwiyiriza mbere yo kuvurwa, ariko bifasha kurya ifunguro ryoroshye mbere yo kuvurwa kugirango wirinde kumva urushye. Irinde kwisiga amaso ku munsi wo guterwa urushinge, kuko ibyo bishobora kubangamira uburyo bwo kwitegura neza.

Nyuma yo guterwa urushinge, ushobora guhura n'ibibazo byo kutabona neza by'igihe gito cyangwa kutumva neza. Ibi bikunze gukemuka mu masaha make. Muganga wawe azatanga amabwiriza yihariye yo kwita ku buzima, harimo n'igihe cyo gusubukura ibikorwa bisanzwe.

Nzamara Igihe Kingana Gite Nkoresha Avacincaptad-pegol?

Uburyo busanzwe bwo kuvura bwa avacincaptad-pegol bukubiyemo guterwa inshinge buri kwezi cyangwa buri mezi abiri, bitewe n'uburwayi bwawe bwihariye n'uburyo wabyitwayemo. Muganga wawe w'amaso azagena uburyo nyabwo bwo gukoresha imiti bitewe n'ibyo ukeneye.

Abantu benshi bakomeza kuvurwa igihe kirekire, kuko geographic atrophy ni indwara idakira kandi ikomeza. Guhagarika kuvurwa bishobora gutuma indwara ikomeza vuba, bishobora gutuma ubuzima bwo kutabona bukomeza.

Muganga wawe azakurikiza uko wabyitwayemo mu kuvurwa binyuze mu bizami by'amaso bisanzwe n'ibizamini byihariye byo gushushanya. Izi gahunda zifasha kumenya niba umuti ukora neza mu kugabanya iterambere ry'indwara kandi niba hari impinduka zikenewe ku buryo uvurwa.

Abantu bamwe bashobora kubona ko ubuzima bwabo buri mu murongo neza mu mezi make ya mbere, mu gihe abandi bashobora gusaba amezi atandatu cyangwa arenga kugirango babone inyungu. Intego ni ukurinda ubuzima bwo kutabona igihe kirekire aho gutegereza kunoza ako kanya.

Ni Ibihe Bikorwa Bigaragara Byatewe na Avacincaptad-pegol?

Kimwe n'imiti yose, avacincaptad-pegol ishobora gutera ibikorwa bigaragara, nubwo atari buri wese ubyumva. Ibikorwa bigaragara bikunze kugaragara bifitanye isano n'uburyo bwo guterwa urushinge ubwabyo aho kuba umuti.

Dore ibikorwa bigaragara bikunze kugaragara ushobora guhura nabyo:

• Kutamererwa neza kw'ijisho ry'igihe gito cyangwa kubabara ahatewe urushinge
• Kureba ibintu bitajegajega bimara amasaha make nyuma yo guterwa urushinge
• Kubona udusimba duto tuzerera cyangwa "floaters" mu mbonerahamwe yawe
• Umutuku w'ijisho woroshye cyangwa kuribwa
• Umubyimbirwe w'ijisho wiyongera by'igihe gito nyuma yo guterwa urushinge
• Kumurika cyangwa amaso arira amazi

Ibi bimenyetso rusange bikunze gukira byonyine mu masaha 24 kugeza kuri 48. Niba bikomeje cyangwa bikiyongera, hamagara muganga w'amaso kugira ngo agufashe.

Nubwo bitaba kenshi, abarwayi bamwe bashobora guhura n'ingaruka zikomeye zisaba ubufasha bwihutirwa. Izi ngorane zitaba kenshi ariko z'ingenzi zirimo:

• Urubabare rukabije rw'ijisho rutagabanuka n'imiti igurishwa itagomba urupapuro rwa muganga
• Gutakaza cyane ubushobozi bwo kureba cyangwa guhinduka kw'imbonerahamwe
• Ibimenyetso by'ubwandu bw'ijisho nk'umutuku wiyongera, gushiramo amazi, cyangwa kubyimba
• Kutagira umwanya w'uruhu rw'ijisho, bishobora gutera urumuri cyangwa igicucu gisa n'umwenda mu mbonerahamwe yawe
• Urubura rukabije imbere mu jisho (endophthalmitis)

Niba uhuye n'izo ngaruka zikomeye, hamagara muganga w'amaso ako kanya cyangwa ushake ubufasha bwihutirwa. Nubwo izi ngorane zitaba kenshi, kuvurwa hakiri kare ni ngombwa kugira ngo ugire ibisubizo byiza.

Ninde utagomba gufata Avacincaptad-pegol?

Avacincaptad-pegol ntikwiriye kuri buri wese ufite atrophy ya geografiya. Muganga wawe azasuzuma neza amateka yawe y'ubuzima n'ubuzima bwawe bw'ubu mbere yo kugusaba ubu buvuzi.

Ntabwo ukwiriye guhabwa uyu muti niba ufite ubwandu bw'ijisho bukora cyangwa kubyimba. Muganga wawe azakenera kuvura ibi bibazo mbere yo gutekereza ku nshinge za avacincaptad-pegol.
