WASHINGTON — Ikigo gishinzwe ibiribwa n'imiti muri Amerika cyatanze uburenganzira bwo gukoresha byihutirwa (EUA) ku ruganda rw'imiti rw'umunyamerika Eli Lilly rukora imiti ivura indwara ya COVID-19 mu buryo bworoheje kugeza ku buringanire ku barwayi bakuru n'abana.

Umuti, bamlanivimab, wemewe kuAbarwayi ba COVID-19bafite imyaka 12 no hejuru bapima nibura ibiro 40, kandi bari mu kaga gakomeye ko kugera kuri COVID-19 ikomeye cyangwa (cyangwa) mu bitaro, nk'uko itangazo rya FDA ryo kuwa mbere ribivuga.

Harimo abafite imyaka 65 cyangwa irenga, cyangwa abafite indwara zimwe na zimwe zidakira.

Antibodies za monoclonal ni poroteyine zakozwe muri laboratwari zigana ubushobozi bw'ubudahangarwa bw'umubiri bwo kurwanya antigens zangiza nka virusi. Bamlanivimab ni antibodies za monoclonal zigamije by'umwihariko kurwanya poroteyine ya SARS-CoV-2, yagenewe kubuza virusi kwinjira no kwinjira mu turemangingo tw'umubiri w'umuntu.

Nubwo umutekano n'ubushobozi bw'ubu buryo bwo kuvura bukomeje gusuzumwa, bamlanivimab yagaragaye mu igeragezwa ry'ubuvuzi kugira ngo igabanye kujya mu bitaro bifitanye isano na COVID-19 cyangwa kujya mu cyumba cy'ubutabazi bwihutirwa (ER) ku barwayi bafite ibyago byinshi byo kwiyongera kw'indwara mu minsi 28 nyuma yo kuvurwa ugereranije n'umuti wa placebo, nk'uko byatangajwe na FDA.

Amakuru ashyigikira EUA kuri bamlanivimab ashingiye ku isesengura ry'agateganyo ryavuye mu igerageza ryakozwe mu cyiciro cya kabiri ry’ubushakashatsi ku bantu bakuru 465 batari mu bitaro bafite ibimenyetso byoroheje kugeza ku biri hagati bya COVID-19.

Muri aba barwayi, 101 bahawe doze ya miligarama 700 ya bamlanivimab, 107 bahabwa doze ya miligarama 2.800, 101 bahabwa doze ya miligarama 7.000 naho 156 bahabwa placebo mu minsi itatu nyuma yo kubona ikizamini cya mbere cya SARS-CoV-2.

Ku barwayi bafite ibyago byinshi byo kwiyongera kw'indwara, 3 ku ijana by'abarwayi bavuwe na bamlanivimab basuwe mu bitaro no mu byumba by'ubutabazi bwihuse (ER) basuwe ugereranije na 10 ku ijana by'abarwayi bavuwe na placebo.

Ingaruka ku mubare w’abanduye virusi no ku kugabanuka kw’abajya mu bitaro no gusura abaganga barwaye indwara z’uruhu, ndetse no ku mutekano, zari zimwe ku barwayi bahabwaga kimwe muri bitatu bya bamlanivimab, nk’uko FDA ibivuga.

EUA yemerera abavuzi gutanga imiti ya bamlanivimab no kuyitanga mu buryo bumwe mu buryo bwo kuyitera mu mitsi.

“Uruhushya rwa bamlanivimab rutangwa na FDA rutanga ikindi gikoresho cy’ubuvuzi ku isonga ry’iki cyorezo,” ibi byavuzwe na Patrizia Cavazzoni, umuyobozi w’agateganyo w’ikigo cya FDA gishinzwe gusuzuma no kuvura imiti. “Tuzakomeza gusuzuma amakuru mashya ku mutekano n’ubushobozi bwa bamlanivimab uko azagenda aboneka.”

Hashingiwe ku isuzuma ry’ibimenyetso byose bya siyansi biboneka, FDA yemeje ko ari ibintu byumvikana kwemera ko bamlanivimab ishobora kugira akamaro mu kuvura abarwayi batari mu bitaro bafite COVID-19 yoroheje cyangwa iringaniye. Kandi, iyo ikoreshejwe mu kuvura COVID-19 ku baturage bemewe, inyungu zizwi n’izishoboka ziruta ingaruka zizwi n’izishoboka ku muti, nk’uko FDA ibivuga.

Ingaruka mbi zishobora guterwa na bamlanivimab zirimo kurwara indwara ya anaphylaxis no guterwa n’imiti, isesemi, impiswi, isereri, kuribwa umutwe, uburyaryate no kuruka, nk’uko bivugwa n’ikigo.

EUA ibaye mu gihe Leta Zunze Ubumwe za Amerika zirenga miliyoni 10 z'abarwayi ba COVID-19 kuwa mbere, nyuma y'iminsi 10 gusa zigeze kuri miliyoni 9. Umubare uheruka w'abandura buri munsi urenga ibihumbi 100, kandi impuguke mu by'ubuzima rusange zaburiye ko igihugu kirimo kwinjira mu cyiciro kibi cyane cy'icyorezo.
