Ni iki Pegvaliase: Ibikoresho, Urutonde rw'imiti, Ingaruka zayo n'ibindi

Pegvaliase ni imiti yihariye isimbura enzyme yagenewe abantu bakuru bafite phenylketonuria (PKU), indwara idasanzwe yo mu buryo bwa genetike aho umubiri udashobora gusenya aside amino phenylalanine. Uyu muti ukora utanga enzyme ibura umubiri wawe ukeneye kugirango utunganye neza phenylalanine, ugufasha kugabanya urwego ruteje akaga mu maraso yawe.

Niba wowe cyangwa umuntu witaho afite PKU, ushobora kumva uremererwa n'uburyo bwo kuvura. Pegvaliase ihagarariye intambwe ikomeye ku bantu batarageze ku rwego rwa phenylalanine binyuze mu mirire gusa, itanga icyizere cyo gucunga neza indwara no guteza imbere imibereho myiza.

Ni iki Pegvaliase ari cyo?

Pegvaliase ni verisiyo yakozwe n'abantu ya enzyme yitwa phenylalanine ammonia lyase umubiri wawe usanzwe ubura niba ufite PKU. Tekereza nk'uko utanga umubiri wawe igikoresho kibura ukeneye kugirango usenye phenylalanine iva muri poroteyine urya.

Uyu muti uza mu ishusho y'amazi asobanutse ukoresha inshinge munsi y'uruhu rwawe, kimwe n'uko abantu barwaye diyabete bakoresha insuline. Izina ry'ubucuruzi rya pegvaliase ni Palynziq, kandi ryagenewe abantu bakuru bafite imyaka 18 n'abarenze bafite PKU.

Igituma pegvaliase idasanzwe ni uko ikomoka ku isoko rya bagiteri kandi yateguwe neza kugirango ikore neza mu mubiri w'umuntu. Uyu muti unyura mu isuku ikomeye kugirango wemeze ko wujuje ibisabwa by'umutekano mbere yo kugera ku barwayi.

Pegvaliase ikoreshwa kubera iki?

Pegvaliase yandikirwa gusa abantu bakuru bafite phenylketonuria (PKU) urwego rwa phenylalanine mu maraso rukomeza kuba rwo hejuru nubwo bakurikiza imirire ikarishye ya poroteyine nkeya. PKU ni indwara ya genetike aho umubiri wawe udashobora gusenya neza phenylalanine, aside amino iboneka mu biryo byinshi birimo poroteyine.

Iyo phenylalanine yiyongera mu maraso yawe, bishobora gutera ibibazo bikomeye by'ubuzima birimo ubumuga bwo mu mutwe, gufatwa n'indwara, ibibazo by'imyitwarire, n'izindi ngorane zo mu bwonko.
