Tirzepatide, igitabo gishya cyitwa reseptor agonist (GLP-1 / GIP), cyitabiriwe cyane mu myaka yashize kubera uruhare rwacyo mu kuvura diyabete. Ariko, ubushobozi bwayo mu ndwara zifata umutima nimiyoboro nimpyiko buragenda bugaragara. Ubushakashatsi buherutse gukorwa bwerekana ko tirzepatide igaragaza imbaraga zidasanzwe ku barwayi bafite ikibazo cyo kunanirwa k'umutima hamwe n'uduce duto twabitswe (HFpEF) hamwe n'umubyibuho ukabije n'indwara zidakira zidakira (CKD). Igeragezwa ry’amavuriro rya SUMMIT ryerekanye ko abarwayi bahabwa tirzepatide bagabanutseho 38% by’impfu z’umutima n’imitsi cyangwa kunanirwa k'umutima bikabije mu byumweru 52, mu gihe ibipimo byerekana imikorere y’impyiko nka eGFR byateye imbere ku buryo bugaragara. Ubu buvumbuzi butanga uburyo bushya bwo kuvura abarwayi bafite ibibazo byo guhindagurika.
Mubice byumutima nimiyoboro y'amaraso, uburyo bwa tirzepatide bwibikorwa birenze amategeko agenga metabolike. Mugukoresha GLP-1 na GIP yakira, bigabanya ingano ya adipocytes, bityo bikagabanya umuvuduko wimikorere yimitsi yibinure kumutima no kunoza ingufu za myocardial metabolism hamwe nubushobozi bwo kurwanya ischemic. Ku barwayi ba HFpEF, umubyibuho ukabije no gutwika karande ni byo bigira uruhare runini, kandi ibikorwa bya tirzepatide byombi byakira reseptor bihagarika neza irekurwa rya cytokine kandi bikagabanya fibrosis ya myocardial, bityo bikadindiza kwangirika kwimikorere yumutima. Byongeye kandi, itezimbere abarwayi-berekana ireme ryamanota yubuzima (nka KCCQ-CSS) nubushobozi bwimyitozo.
Tirzepatide irerekana kandi ingaruka zitanga uburinzi bwimpyiko. CKD ikunze guherekezwa no guhungabana kwa metabolike no gutwika urwego rwo hasi. Ibiyobyabwenge bikora binyuze munzira ebyiri: kunoza imiterere yisi yose kugirango igabanye proteinuria, kandi ibuza inzira ya fibrosis yimpyiko. Mu igeragezwa rya SUMMIT, tirzepatide yazamuye cyane urwego rwa eGFR rushingiye kuri cystatine C kandi igabanya albuminuria hatitawe ku kuba abarwayi bafite CKD, byerekana kurinda impyiko. Ubu bushakashatsi butanga inzira nshya yo kuvura indwara ya diabete ya diabete nizindi ndwara zidakira.
Igitangaje cyane ni agaciro ka tirzepatide ku barwayi bafite “triad” y’umubyibuho ukabije, HFpEF, na CKD - itsinda rifite ubusanzwe butamenyekana. Tirzepatide itezimbere umubiri (kugabanya ibinure byamavuta no kongera imitsi ihindagurika ryimitsi) kandi igahindura inzira yumuriro, bityo igatanga uburinzi buhuriweho ningingo nyinshi. Mugihe ibimenyetso bya tirzepatide bikomeje kwaguka, byiteguye guhinduka imiti yifatizo mugucunga indwara ziterwa na metabolike hamwe nibibazo.
