Mwina mwamvapo kuti pali njira zatsopano komanso zapamwamba zochizira matenda akuluakulu monga khansa. Nthawi zina dokotala anganene kuti, "Pali mankhwala apadera a izi omwe amagwiritsa ntchito chitetezo chathu chamthupi." Lero, tikambirana za mankhwala omwe apanga chitukuko chachikulu mu zamankhwala. Izi zimatchedwa ma monoclonal antibodies. Ngakhale kuti dzinali ndi lovuta pang'ono, nkhaniyi ndi yosavuta. Tiyeni tiwone chomwe ichi ndi.
Kodi ma antibodies a monoclonal awa ndi chiyani?
Mwachidule, awa ndi mapuloteni apadera opangidwa mu labu omwe amagwira ntchito mofanana ndi ma antibodies omwe matupi athu amapanga mwachilengedwe.
Tsopano ganizirani izi, thupi lathu lili ngati dziko. Pali gulu lankhondo loteteza dziko lino. Gulu lankhondo limenelo ndi chitetezo chathu chamthupi. Majeremusi ndi zinthu zomwe zimayambitsa matenda (zomwe timazitcha ma antigen ) zomwe zimachokera kunja zili ngati adani omwe akubwera m'dziko lathu. Ma antibodies awa ndi asilikali apadera m'gulu lathu lankhondo. Ntchito yawo ndi kupeza, kugwira, ndikuwononga adani awa.
Nthawi zina, ngakhale zinthu monga maselo a khansa zimakula m'thupi lathu, chitetezo chathu cha mthupi sichingathe kuzizindikira. Pamenepo ndi pamene timapempha thandizo lakunja.
Ma antibodies a monoclonal , mwachidule, ali ngati asilikali ophunzitsidwa bwino, anzeru kwambiri, opangidwa mu labu. "Mono" amatanthauza "chimodzi." "Clonal" amatanthauza "kopi." Izi zikutanthauza kuti, antibody imodzi yanzeru kwambiri imasankhidwa ndipo makope ake mamiliyoni ambiri amapangidwa mu labu. Gulu lankhondo la ma antibodies amenewa limalowetsedwa m'matupi athu ngati mankhwala. Amapita molunjika ku maselo omwe amayambitsa matendawa (monga maselo a khansa), amamatira kwa iwo, ndikuthandiza chitetezo chathu cha mthupi kuwawononga.
Ngati dzina la mankhwala amtunduwu omwe mwapatsidwa lili ndi zilembo zitatu "mab" kumapeto (monga Trastuzumab, Rituximab), zikutanthauza kuti ndi Monoclonal Antibody.
Kodi kusiyana pakati pa monoclonal ndi polyclonal ndi kotani?
Izi ndizosavuta kwambiri.
- Monoclonal: Izi zili ngati sniper. Pali cholinga chimodzi chokha. Ma antibodies awa adapangidwa kuti azilumikizana ndi antigen imodzi yokha. Chifukwa chake, ndi enieni kwambiri ndipo sadzaphonya cholingacho.
- Polyclonal: "Poly" amatanthauza "ambiri." Izi ndi gulu la ma antibodies osiyanasiyana. Monga gulu lankhondo lomwe lili ndi zida zosiyanasiyana, amatha kuukira mitundu ingapo ya ma antigen .
Ma antibodies a monoclonal amagwiritsidwa ntchito kwambiri pochiza chifukwa amalimbana mwachindunji.
Kodi izi zimagwiritsidwa ntchito pa chiyani?
Njira yochiritsira iyi tsopano ikugwiritsidwa ntchito pazinthu zambiri. Kuyambira kafukufuku mpaka kuchiritsa matenda.
| Malo ogwiritsira ntchito | Kufotokozera kosavuta |
|---|---|
| Kuzindikira matenda | Amagwiritsidwa ntchito m'ma laboratories kuti adziwe chinthu. Mwachitsanzo, zida zoyesera mimba zomwe mumagwiritsa ntchito kunyumba zimagwiranso ntchito ndi ukadaulo uwu. |
| Kugawa minofu ndi magazi | Izi zimagwiritsidwa ntchito pofufuza ngati minofu ya wopereka ndi wolandirayo ikugwirizana panthawi yoika chiwalo. |
| Kuchiza matenda | Ichi ndiye chinthu chofunikira kwambiri. Izi zimagwiritsidwa ntchito pochiza matenda ambiri, monga khansa ndi nyamakazi. |
Ndi matenda ati omwe amachiritsidwa ndi ma antibodies a monoclonal?
Njira yochiritsira iyi ikugwiritsidwa ntchito bwino pa matenda angapo. Ena mwa iwo ndi awa:
- Khansa: Ya mitundu yosiyanasiyana ya khansa monga khansa ya m'mawere, khansa ya m'matumbo, ndi khansa ya magazi.
- Pofuna kupewa kukana kuikidwa chiwalo: Letsani thupi kukana chiwalo chomwe chaikidwa (monga impso, chiwindi).
- Matenda a Autoimmune: Matenda omwe chitetezo chamthupi chimaukira maselo ake, monga nyamakazi ndi matenda a Crohn.
- Matenda a chifuwa: Pa mphumu yoopsa ndi matenda ena a chifuwa.
- Matenda: Amagwiritsidwanso ntchito pochiza matenda ena opatsirana ndi mavairasi, monga COVID-19.
- Matenda a mafupa
- Matenda a maso
- Mutu wopweteka kwambiri
- Cholesterol yambiri
Kodi chithandizochi chimaperekedwa bwanji?
Mankhwalawa nthawi zambiri amaperekedwa ngati madzi amchere mumtsempha (olowetsedwa m'mitsempha kapena m'mitsempha). Nthawi zambiri amaperekedwa mu chipinda chapadera (malo olowetsedwa) kuchipatala kapena kuchipatala. Anthu ena angapo akhoza kulandira chithandizo kumeneko nthawi yomweyo pamene mukulandira chithandizo.
Ngati iyi ndi nthawi yanu yoyamba kulandira chithandizochi, dokotala wanu angakupempheni kuti mubwere ndi wachibale wanu kuti adziwe za chithandizochi komanso zomwe mungayembekezere pambuyo pake. Pa chithandizo choyamba, ogwira ntchito zachipatala adzakuyang'anirani mosamala kuti aone ngati muli ndi vuto lililonse la ziwengo .
Kawirikawiri, ma antibodies ena a monoclonal amaperekedwanso ngati jakisoni wa subcutaneous. Ngati zili choncho, mudzaphunzitsidwa momwe mungadzipatsire jakisoni.
Kodi pali mitundu yosiyanasiyana ya chithandizochi?
Inde, asilikali "opangidwa ndi ma clone" awa amatha kuchita ntchito zosiyanasiyana. Chifukwa chake, pali mitundu itatu yayikulu.
| Mtundu | Mwachidule... |
|---|---|
| Ma antibodies a monoclonal opanda kanthu | Asilikali awa amagwira ntchito okha. Amapita molunjika ku selo ya adani ndikupereka chizindikiro kwa chitetezo cha mthupi kuti chiwononge. |
| Ma Antibodies a Monoclonal Ogwirizana | Asilikali awa sapita okha. Amanyamula "bomba." Izi zikutanthauza kuti, tinthu ta radioactive kapena mankhwala oletsa khansa amamangiriridwa ku antibody iyi. Msilikaliyo amapita ku selo ya mdani ndikuphulitsa bomba ili. Kenako kuwonongeka kumangokhala kwa selo ya mdani. |
| Ma Antibodies a Bispecific Monoclonal | Awa ndi asilikali aluso kwambiri. Zili ngati ali ndi manja awiri. Mukagwira selo la mdani ndi dzanja limodzi, mumagwira selo la chitetezo cha mthupi lathu ndi dzanja lina ndikunena kuti, "Nayi mdani, menyani." Amalumikizana mwachindunji. |
Kodi ubwino wa njira imeneyi yochiritsira ndi wotani?
- Chithandizo cholunjika: Ichi ndiye ubwino waukulu. Mosiyana ndi mankhwala a chemotherapy okhazikika, chithandizochi sichiwononga maselo athanzi kwenikweni. Chifukwa chimakhudza munthu amene akungofuna chithandizo, palibe zotsatirapo zoyipa zambiri.
- Kupambana kwakukulu: Njira yochiritsira iyi yapereka zotsatira zabwino kwambiri pa matenda monga mitundu ina ya khansa.
- Ubwino: Popeza amapangidwa mu labotale, gulu lililonse la mankhwala opangidwa ndi la muyezo womwewo.
- Kupanga zinthu zambiri: Izi tsopano zitha kupangidwa mochuluka.
Kodi pali zoopsa kapena zovuta zilizonse ndi chithandizochi?
Monga momwe zimakhalira ndi chithandizo chilichonse, pali zoopsa zina zomwe zingachitike. Koma musadandaule, dokotala wanu adzakufotokozerani zonse.
Chofunika kwambiri ndi kudziwitsa ogwira ntchito zachipatala nthawi yomweyo ngati mukukumana ndi zizindikiro zachilendo panthawi ya chithandizochi kapena pambuyo pake.
Mavuto ofala ndi awa:
- Kulowetsedwa kwa mankhwala: Izi zitha kuchitika nthawi yomwe mankhwalawo alowetsedwa m'mitsempha kapena nthawi yomweyo atangolowa m'mitsempha. Izi nthawi zambiri sizimakhala zoopsa.
- Kutupa pakhungu
- Malungo
- Kunjenjemera chifukwa cha chimfine
- Kuvuta kupuma
- Kutuluka thukuta
- Kusintha kwa kuthamanga kwa magazi
- Kuwonjezeka kwa kugunda kwa mtima
Ngati chinthu chonga ichi chichitika, chingathetsedwe mwa kuchepetsa kuchuluka kwa mankhwala kapena kusiya kwa kanthawi.
- Zotsatira zoopsa kwambiri (koma sizimawonedwa kawirikawiri):
- Acute Anaphylaxis: Ichi ndi chiwopsezo chachikulu cha ziwengo chomwe chimachitika mwadzidzidzi ndipo chingayambitse imfa. Ichi ndichifukwa chake kuyang'anitsitsa mosamala mukayamba kupereka chithandizo.
- Matenda a Cytokine Release Syndrome (CRS): Uwu ndi mkhalidwe womwe chitetezo cha mthupi chimayamba kugwira ntchito mopitirira muyeso ndipo chimayambitsa "mkuntho." Izi zitha kuwononga ziwalo.
- Matenda a seramu: Chomwe chimachitika pamenepa ndi chakuti thupi lathu limayamba kuukira puloteni yomwe (antibody) yomwe idaperekedwa ngati chithandizo.
Zoopsa zina zingakhale zenizeni pa matenda omwe akuchiritsidwa. Mwachitsanzo, matenda a tumor lysis mu chithandizo cha khansa.Izi zitha kuchitika pamene maselo a khansa awonongeka mofulumira, ndipo impso sizingathe kugwira ntchito ndi zinyalala zomwe zimapanga.
Kodi zimatenga nthawi yayitali bwanji kuti munthu achire pambuyo pa chithandizo?
Nthawi yomwe imatenga kuti mankhwalawa aperekedwe kudzera m'mitsempha imatha kusiyana. Mwachitsanzo, m'machiritso ena a COVID-19, mankhwalawa amaperekedwa kwa ola limodzi, kenako ola limodzi loyang'aniridwa.
Ndicho chifukwa chake muyenera kubwera ndi wachibale wanu tsiku loyamba. Ngati palibe zotsatirapo zoyipa, mutha kubwera nokha ku chithandizo chotsatira. Ngati simunatope mutalandira chithandizo, funsani dokotala wanu ngati mungathe kupitiriza ndi zochita zanu zachizolowezi (ntchito, sukulu). Zimatengera momwe mulili komanso thanzi lanu lonse.
Kodi ndiyenera kulankhula ndi dokotala za izi?
Inde ndithu.
- Ngati mukulandira kale chithandizo cha monoclonal antibody ndipo mukukumana ndi zizindikiro zachilendo (monga zomwe takambirana kale), imbani dokotala wanu nthawi yomweyo kapena pitani ku Dipatimenti Yodzidzimutsa (ETU).
- Ngati muli ndi vuto lomwe ladziwika kuti ndi njira yabwino yothandizira, lankhulani ndi dokotala wanu ngati chithandizo cha monoclonal antibody ichi chili choyenera kwa inu. Iye adzawunika vuto lanu, adzakufotokozerani zabwino ndi zoyipa zake, ndikukufotokozerani ngati ndi loyenera kwa inu.
Uthenga Wopita Nawo Kunyumba
- Ma antibodies a monoclonal ndi mankhwala apadera omwe amagwiritsa ntchito makope a ma antibodies athu, opangidwa mu labotale.
- Izi ndi "mankhwala ochiritsira omwe amaperekedwa mwachindunji" kotero kuti maselo athanzi sawonongeka kwambiri.
- Izi tsopano zikugwiritsidwa ntchito bwino pochiza matenda ambiri akuluakulu, monga khansa, nyamakazi, ndi ziwengo.
- Mankhwalawa nthawi zambiri amaperekedwa ngati madzi amchere m'mitsempha. Zinthu zina zingachitike panthawi ya chithandizo komanso pambuyo pake.
- Ndikofunikira kwambiri kuuza dokotala wanu zizindikiro zilizonse zachilendo nthawi yomweyo.
- Dokotala wanu yekha ndi amene angasankhe ngati chithandizochi chili choyenera kwa inu, choncho kambiranani naye zonse.
