Kodi mumamva bwanji chisoni ngati mayi kapena bambo mwana wanu akamavutika kuthamanga, kulumpha, kukwera masitepe, kapena kudzuka atakhala pansi? Duchenne Muscular Dystrophy (DMD) ndi matenda a majini omwe amafooketsa minofu pang'onopang'ono ndipo amakhudza makamaka anyamata. Ngakhale kuti palibe mankhwala ochiritsira matendawa, mankhwala atsopano ayambitsidwa padziko lonse lapansi kuti athetse matendawa ndikupangitsa moyo wa mwana kukhala wosavuta. Lero, tikambirana za mankhwala a majini otchedwa Elevidys, omwe abweretsa chiyembekezo chatsopano.
Kodi mankhwala otchedwa Elevidys amagwira ntchito bwanji kwenikweni?
Kuti timvetse izi, choyamba tiyeni tiwone momwe DMD imakulira. Taganizirani za minofu m'thupi lathu ngati nyumba yolimba. Kuti nyumbayi ikhale yolimba komanso yosagwa, tifunika puloteni yapadera yotchedwa 'dystrophin'. Ili ngati simenti yomwe imagwirizanitsa njerwa m'nyumba.
Kwa ana omwe ali ndi matenda a shuga, chifukwa cha kusintha kwa majini, 'simenti' iyi yotchedwa dystrophin siipangidwa bwino. Izi zimapangitsa kuti zomangira zotchedwa minofu zifooke pang'onopang'ono ndikugwa. Choyamba, minofu ya miyendo ndi chiuno imayamba kufooka. Izi zimapangitsa kuti zikhale zovuta kuthamanga, kulumpha, ndi kukwera masitepe. Pakapita nthawi, kufooka kumeneku kungakhudzenso manja, mtima, ndi mapapo.
Elevidys ndi mankhwala a majini. Mwachidule, zimaphatikizapo kupereka kopi yayifupi ya jini yomwe ili ndi malangizo opangira dystrophin kukhala maselo a minofu kudzera mu kachilombo kapadera (vector).
Izi zimathandiza thupi la mwana kupanga mtundu waufupi, koma wogwira ntchito bwino wa puloteni ya dystrophin. Madokotala akuyembekeza kuti 'simenti yatsopano' iyi ichepetsa liwiro lomwe minofu imafooka.
Kodi chithandizochi chimaperekedwa bwanji?
Iyi si mapiritsi a tsiku ndi tsiku. Elevidys ndi mankhwala omwe amaperekedwa kamodzi kokha pa moyo wonse.
Izi zimaperekedwa ngati njira yothira, monga saline, mu mitsempha. Koma izi sizingachitike kunyumba. Zimaperekedwa kuchipatala, motsogozedwa ndi madokotala . Chifukwa mwanayo amafunika kuyang'aniridwa mosamala kwa maola angapo pamene chithandizo chikuperekedwa.
Asanayambe kulandira chithandizo, mankhwala a steroid amtundu wa corticosteroid amayamba kugwiritsidwa ntchito kuti achepetse chiopsezo cha zotsatirapo zoyipa. Dokotala adzaonetsetsanso kuti mwanayo walandira katemera wake wonse.
Kodi zotsatira za kafukufukuyu ndi ziti?
Kafukufuku wambiri wachitika pakugwira ntchito bwino komanso chitetezo cha mankhwalawa. Kafukufukuyu waphunzira kusiyana pakati pa ana omwe adapatsidwa Elevidys ndi omwe sanapatsidwe (gulu la placebo). Chifukwa chake, nazi zina mwa zabwino zazikulu zomwe zapezeka.
| Phindu | Kufotokozera kosavuta |
|---|---|
| Kuwonjezeka kwa kuyenda (Chiwerengero cha NSAA) | Pa mayeso a North Star Ambulatory Assessment (NSAA), omwe amayesa kuyenda kwa ana, ana omwe adamwa Elevidys adapeza mapointi awiri apamwamba kuposa ana omwe sanamwe mankhwalawo. Izi zikutanthauza kuti luso lawo lochita zinthu zatsiku ndi tsiku linakula pang'ono. |
| Kuwonjezeka kwa dystrophin m'minofu | Mu kafukufukuyu, pamene gawo laling'ono la minofu ya ana linatengedwa ndi kufufuzidwa (biopsy), kuchuluka kwa puloteni ya dystrophin m'maselo a minofu ya ana omwe adalandira Elevidys kunawonjezeka kwambiri. |
| Kuthamanga kwa ntchito | Poyesa nthawi yomwe imatenga kuti mudzuke mutagona, muthamange mamita 10, ndikukwera masitepe 4, ana omwe adalandira Elevidys adatha kuchita ntchito izi mwachangu pang'ono. |
Koma kumbukirani izi. Si ana onse omwe adzapeza zotsatira zofanana. Inu ndi dokotala wanu muyenera kukambirana zotsatira zake pamodzi kuti mudziwe momwe chithandizocho chathandizira.
Kodi pali milandu ina iliyonse pamene chithandizochi sichiyenera kuperekedwa?
Inde, ndithudi. Si ana onse omwe ali ndi matenda a shuga omwe angapatsidwe mankhwalawa. Pali zochitika zina zapadera zomwe chithandizo cha Elevidys sichiyenera kuperekedwa.
- Zilema zinazake za majini: Ana omwe ali ndi zilema zinazake mu jini zomwe zimayambitsa DMD (monga kuchotsedwa kwa exon 8 kapena exon 9 ) sapatsidwa chithandizochi. Izi zitha kuzindikirika poyesa majini musanalandire chithandizo.
- Kuwonjezeka kwa kuchuluka kwa ma antibodies:Mankhwala a Elevidys sayenera kuperekedwa kwa ana omwe ali ndi ma antibodies ambiri olimbana ndi kachilomboka (AAVrh74 vector) omwe amanyamula. Izi zili choncho chifukwa ma antibodies amenewo amatha kuletsa mankhwalawa kufika m'minofu moyenera ndipo angayambitse zotsatirapo zoyipa kwambiri. Izi zitha kuzindikirikanso pasadakhale ndi mayeso a magazi.
- Matenda Ogwira Ntchito: Ngati mwana ali ndi matenda monga malungo, chimfine, chifuwa, kapena kupweteka m'mimba panthawi yoyambira chithandizo, chithandizo sichidzayamba mpaka atachira kwathunthu.
Zotsatirapo zake ndi momwe mungathanirane nazo?
Monga momwe zimakhalira ndi mankhwala ena aliwonse, Elevidys ingayambitse zotsatirapo zoyipa. Zotsatirapo zoyipa kwambiri ndi nseru ndi kusanza . Izi nthawi zambiri zimachitika m'masabata ochepa oyamba. Ngati mwana wanu ali ndi zizindikiro izi, uzani dokotala wanu. Adzakupatsani mankhwala othandizira kusanza. Ndikofunikiranso kumwa madzi ambiri kuti mupewe kutaya madzi m'thupi.
Kuphatikiza apo, ndi bwino kudziwa zotsatirapo zina zomwe zingakhalepo komanso zizindikiro zake.
| Zotsatira zoyipa | Zinthu zofunika kuziganizira |
|---|---|
| Malungo | Malungo akhoza kukhala chizindikiro cha matenda, choncho ngati mukuyamba kutentha thupi, dziwitsani dokotala wanu. |
| Kuchuluka kwa ma platelet m'magazi (Thrombocytopenia) | Ma platelets amathandiza magazi kuundana pamene mukutuluka magazi. Ngati magaziwo ali ochepa,
|
| Zotsatirapo pa chiwindi | Ngati maso kapena khungu loyera likusintha kukhala lachikasu, izi zitha kukhala chizindikiro cha vuto la chiwindi. Dokotala wanu nthawi zonse amafufuza izi pochita mayeso a magazi (LFTs). |
| Zotsatira pa mtima | Ngati mukumva kupweteka pachifuwa kapena kupuma movutikira, kungakhale chizindikiro cha kutupa kwa minofu ya mtima. Uzani dokotala wanu nthawi yomweyo. |
Chofunika kwambiri ndikulankhula ndi dokotala wanu popanda kukayikira za zizindikiro zilizonse zomwe mukuganiza kuti sizodziwika.
Ndi mayeso ati omwe adzachitike chithandizo chisanachitike komanso chitatha?
Inde, chifukwa chakuti chithandizochi ndi chovuta, mayeso angapo amachitidwa kuti amvetsetse bwino thanzi la mwana.
- Mayeso a majini: Tsimikizani ngati mwanayo ali ndi DMD yokha komanso ngati pali zolakwika zilizonse za majini zomwe zingapangitse kuti Elevidys asayenerere kulandira chithandizo.
- Mayeso a ma antibodies: Yang'anani kuchuluka kwa ma antibodies motsutsana ndi kachilombo ka AAVrh74 komwe tidakambirana kale.
- Kuchuluka kwa magazi (CBC): Yang'anani matenda kapena matenda ena a magazi.
- Mayeso a ntchito ya chiwindi (LFT): Yang'anirani thanzi la chiwindi musanayambe komanso mutalandira chithandizo.
- Thanzi la minofu ya mtima (Troponin test): Dziwani ngati mtima wakhudzidwa.
- Kuchuluka kwa ma platelet m'magazi: Yang'anirani kuchepa kwa kuchuluka kwa ma platelet m'magazi mutalandira chithandizo.
Mayeso onsewa amachitika kuti atsimikizire chitetezo cha mwana momwe angathere.
Uthenga Wopita Nawo Kunyumba
- Elevidys ndi mankhwala a majini omwe amaperekedwa kamodzi kokha pa moyo wa Duchenne Muscular Dystrophy (DMD). Si mankhwala a matendawa, koma amapereka chiyembekezo chochepetsa kufooka kwa minofu.
- Imagwira ntchito pothandiza thupi kupanga puloteni ya dystrophin yomwe ndi yayifupi komanso yogwira ntchito .
- Mankhwalawa si oyenera mwana aliyense amene ali ndi matenda a shuga. Amafunika kuyezetsa majini ndi magazi kuti adziwe ngati ali oyenerera kulandira chithandizo.
- Chithandizochi chimaperekedwa ngati jakisoni m'mitsempha m'chipatala, moyang'aniridwa ndi dokotala .
- Zotsatirapo zina monga kusanza ndi nseru zingachitike. Muyeneranso kudziwa za matenda aakulu monga kuchepa kwa ma platelet m'magazi. Ngati pali vuto lililonse, uzani dokotala wanu nthawi yomweyo.
- Uwu ndi mankhwala ovuta kwambiri komanso atsopano, choncho onetsetsani kuti mwakambirana zonse ndi dokotala wa mwana wanu ndipo muwafotokozere.
