Aflibercept (ABZV) ni iki: Ibikoreshwa, Urutonde rw'imiti, Ingaruka ziterwa n'iyo miti n'ibindi

Aflibercept ni umuti ufasha kuvura indwara zikomeye zo mu maso zishobora gushyira mu kaga imboni zawe. Uyu muti wateguwe by'umwihariko kugira ngo wibasire poroteyine yitwa VEGF itera imikurire idasanzwe y'imitsi y'amaraso mu jisho ryawe. Uyu muti utangwa nk'urushinge rutangwa mu jisho ryawe na muganga wawe, kandi nubwo bishobora gutera ubwoba, ni uburyo bwo kuvura bwemejwe neza bwafashije abantu benshi kubungabunga imboni zabo.

Aflibercept ni iki?

Aflibercept ni ubwoko bw'umuti witwa VEGF inhibitor ubuza poroteyine zangiza mu jisho ryawe. Tekereza VEGF nk'ikimenyetso kibwira ijisho ryawe gukura imitsi mishya y'amaraso, ariko rimwe na rimwe iki kimenyetso kigenda nabi maze kigakora imitsi ivamo amaraso cyangwa akava. Aflibercept ikora nk'ingabo, ibuza ibi bimenyetso byangiritse kandi igafasha ijisho ryawe gukira neza.

Uyu muti ni poroteyine yakozwe muri laboratori yigana ubushobozi bw'umubiri wawe bwo kugenzura imikurire y'imitsi y'amaraso. Itangwa binyuze mu rusinge ruto cyane rutangwa mu vitreous, ari yo kintu gisa na jeli cyuzura hagati y'ijisho ryawe. Ubu buryo bwo gutanga umuti butuma umuti ugera neza aho ukenewe cyane.

Aflibercept ikoreshwa mu kuvura iki?

Aflibercept ivura indwara nyinshi zikomeye zo mu maso zishobora gutera ubuhumyi niba zitavuwe. Muganga wawe ashobora kugusaba uyu muti niba ufite macular degeneration yatewe n'imyaka, edema ya macular ya diyabete, cyangwa ubwoko runaka bwo guhagarara kw'imitsi yo mu jisho.

Indwara isanzwe ivurwa na aflibercept ni macular degeneration yatewe n'imyaka, aho imitsi idasanzwe y'amaraso ikura munsi ya retina kandi ikavamo amazi cyangwa amaraso. Ibi biva bishobora gutuma imboni zawe zisa n'izitabonetse cyangwa zikagoreka, bigatuma bigoranye gusoma, gutwara imodoka, cyangwa kumenya mu maso.

Abantu barwaye diyabete bashobora kurwara diyabete ya macular edema, aho isukari nyinshi mu maraso yangiza udutsi duto tw'amaraso muri retina, bigatuma tuvamo amazi akajya muri macula. Ukwo kubyimba bishobora kugira ingaruka zikomeye ku mbono yawe ikomeye, yo hagati ukoresha mu mirimo irambuye.

Muganga wawe ashobora kandi gukoresha aflibercept mu kuvura imitsi ya retina iziba, ibyo bibaho iyo imitsi y'amaraso muri retina yawe izibye. Iyo mitsi izibye bishobora gutuma amazi yiyongera bikaba byatera ibibazo by'imbono bitandukanye kuva ku guhumirwa guto kugeza ku gutakaza imbono cyane.

Aflibercept ikora ite?

Aflibercept ikora ibuza poroteyine yitwa VEGF itera imitsi y'amaraso idasanzwe gukura mu jisho ryawe. Iyo ufite indwara zimwe na zimwe z'amaso, umubiri wawe ukora VEGF nyinshi cyane, itegeka ijisho ryawe gukora imitsi mishya y'amaraso yoroshye kandi ivamo amazi byoroshye.

Uyu muti ufatwa nk'umuti ukomeye kandi ufasha mu kuvura indwara ziteye ubuzima bw'imbono akaga. Ifatana na poroteyine ya VEGF nk'urufunguzo rwinjira mu gikingi, ikabuza ko zatera gukura kw'imitsi y'amaraso ifite ibibazo. Mu guhagarika iyi nzira, aflibercept ifasha kugabanya kubyimba, kuva amaraso, no kuva amazi mu jisho ryawe.

Ingaruka za aflibercept zirashobora kumara ibyumweru byinshi kugeza ku mezi, niyo mpamvu udakeneye imiti ya buri munsi. Ijisho ryawe ritunganya buhoro buhoro umuti, kandi muganga wawe azagenzura uko ukora neza binyuze mu bizami by'amaso bisanzwe n'ibizamini by'amashusho.

Nkwiriye gufata Aflibercept nte?

Aflibercept itangwa gusa nk'urushinge mu jisho ryawe na muganga w'amaso ubifitiye uburenganzira mu rwego rw'ubuvuzi. Ntushobora gufata uyu muti uri mu rugo, kandi ntiboneka nk'amatonyi y'amaso cyangwa ibinini.

Mbere yo guterwa urushinge, muganga wawe azahanagura ijisho ryawe n'agace gakikije neza kugira ngo birinde kwandura. Bazakoresha amatonyi yo gutuma utabona ububabare kugira ngo bakore uburyo bworoshye uko bishoboka kose. Uko guterwa urushinge bifata amasegonda make, nubwo gahunda yose ishobora kumara iminota 30 kugeza ku isaha.

Ntabwo bisaba kwiyiriza ubusa cyangwa kwirinda kurya mbere yo kujya kwa muganga, ariko ugomba gutegura umuntu uzakujyana gutaha nyuma yaho. Ijisho ryawe rishobora kumva ritameze neza cyangwa imboni yawe igahumirana by'igihe gito nyuma yo guterwa urushinge.

Muganga wawe azaguha amabwiriza arambuye yerekeye amavuta yo mu maso cyangwa izindi miti yo gukoresha nyuma yo guterwa urushinge. Ni ngombwa gukurikiza aya mabwiriza neza kugira ngo ugabanye ibyago byo kwandura kandi bifashe ijisho ryawe gukira neza.

Nzakoresha Aflibercept igihe kingana iki?

Igihe cyo kuvurwa na aflibercept gitandukana bitewe n'uburwayi bwawe bwihariye n'uburyo wemera imiti. Abantu benshi bakeneye kuvurwa igihe kirekire mu mezi cyangwa imyaka kugira ngo bagumane iterambere ry'imboni zabo.

Mbere na mbere, birashoboka ko uzahabwa inshinge buri byumweru 4 kugeza kuri 8 mu mezi make ya mbere. Muganga wawe azakurikirana neza uko urwayi rwawe rumeze muri iki gihe kugira ngo arebe uko ijisho ryawe ryitwara ku miti. Abantu bamwe babona impinduka mu mboni zabo mu byumweru bike, mu gihe abandi bishobora kubatwara amezi menshi kugira ngo babone impinduka zigaragara.

Nyuma y'icyiciro cyo kuvurwa cya mbere, muganga wawe ashobora kongera igihe hagati y'inshinge niba uburwayi bwawe bugihagaze neza. Abantu bamwe bashobora gukoresha imiti buri mezi 3 kugeza kuri 4 hagati y'imiti, mu gihe abandi bakeneye inshinge zikunze gukoreshwa kugira ngo bagumane imboni zabo.

Muganga w'amaso azakoresha ibizamini byihariye byerekana ishusho n'isuzuma ry'imboni kugira ngo amenye gahunda nziza yo kuvura yawe. Ntukigere uhagarika imiti ku bushake bwawe, kuko ibi bishobora gutuma uburwayi bwawe burushaho kuba bubi kandi bigatuma utakaza imboni.

Izindi nzira za Aflibercept

Niba aflibercept itagukwiriye cyangwa idakora neza bihagije, muganga wawe afite izindi nzira nyinshi zo kuvura zihari. Izindi inhibitors za VEGF nka ranibizumab (Lucentis) na bevacizumab (Avastin) zikora mu buryo bumwe kandi zishobora kuba amahitamo meza kuri wowe.

Ranibizumab yagenewe cyane kuvura amaso kandi ifite amateka maremare y'umutekano n'ubushobozi. Itangwa nk'inkingo zisa na aflibercept, nubwo gahunda yo gutanga imiti ishobora kuba itandukanye.

Bevacizumab yabanje gukorwa kugirango ivure kanseri ariko byagaragaye ko ifite akamaro ku ndwara z'amaso. Akenshi ihendutse kuruta izindi nzira, nubwo ikoreshwa hanze y'icyapa cyo kuvura amaso.

Kubera ibibazo bimwe na bimwe, muganga wawe ashobora kugusaba gukoresha laser, photodynamic therapy, cyangwa inkingo za steroid aho gukoresha cyangwa kongera ibintu byangiza VEGF. Uburyo bwo kuvura bwiza buterwa n'ikibazo cyawe cyihariye, ubuzima bwawe muri rusange, n'uburyo witwara neza ku miti itandukanye.

Ese Aflibercept iruta Ranibizumab?

Bombi aflibercept na ranibizumab ni imiti myiza yo kuvura indwara z'amaso, kandi nta numwe uruta undi. Guhitamo hagati yabo biterwa n'ikibazo cyawe cyihariye, uburyo ushobora kuza kuvurwa, n'uburyo ijisho ryawe ryitwara kuri buri muti.

Aflibercept ishobora kugira akamaro gato ko akenshi itangwa kenshi kuruta ranibizumab, bivuze ko urugendo ruto ku biro by'abaganga. Ubushakashatsi bumwe buvuga ko aflibercept ishobora gukora neza gato kubwoko bumwe bw'indwara y'amaso ya diyabete.

Ranibizumab yabonetse igihe kirekire kandi ifite amateka maremare y'umutekano, abaganga bamwe n'abarwayi bakunda. Nanone yagenewe cyane kuvura amaso, mugihe aflibercept ikoreshwa kuvura amaso na kanseri.

Muganga wawe w'amaso azatekereza ibintu nk'icyemezo cyawe cyihariye, uburyo ikibazo cyawe cyateye imbere, ubuzima bwawe muri rusange, n'ibyo ukunda wowe ubwawe mugihe uhitamo hagati yiyi miti. Abantu benshi babaho neza hamwe n'uburyo ubwo aribwo bwose, kandi akenshi urashobora guhindura hagati yabo niba bibaye ngombwa.
