Icyo Ecallantide ari cyo: Ibyo ikoreshwa, urugero rwo gufata, ingaruka zayo n'ibindi

Ecallantide ni umuti wandikirwa na muganga wagenewe kuvura ibitero byo kubyimba bikomeye kandi byihuse ku bantu bafite indwara ya hereditary angioedema (HAE). Uyu muti wihariye uterwa mu nshinge ukora ubugufi buhagarika poroteyine zimwe na zimwe mu mubiri wawe zitera ibitero byo kubyimba bikomeye, cyane cyane ahazengurutse mu maso, mu muhogo, n'ahandi hantu h'ingenzi.

Niba wowe cyangwa umuntu muziranye yaranzwe na HAE, gusobanukirwa uyu muti birashobora kugufasha kumva witeguye kandi ufite icyizere cyo gucunga iyi ndwara idasanzwe ariko ikomeye. Reka tunyuremo ibyo byose ukeneye kumenya kuri ecallantide mu magambo yoroshye kandi asobanutse.

Ecallantide ni iki?

Ecallantide ni umuti wihariye wa biyoloji ukora nk'urufunguzo rwihariye, ruhagarika poroteyine zihariye zifite izina rya kallikreins zitera ibitero byo kubyimba ku barwayi ba HAE. Tekereza nk'igikoresho cyizewe gihaguruka mu gihe cy'akaga kugira ngo gifashe guhagarika inzira yo kubyimba mbere yuko iba ikomeye cyane.

Uyu muti ubarirwa mu cyiciro cyitwa kallikrein inhibitors, bivuze ko wibanda by'umwihariko ku mpamvu nyamukuru y'ibitero bya HAE aho kuvura gusa ibimenyetso. Abaganga babifata nk'umuti wo gutabara kuko ukoreshwa mu gihe cy'ibitero byo kubyimba bikomeye, ntabwo ukoreshwa nk'umuti wo gukumira buri munsi.
