Yini i-Etelcalcetide: Ukusetshenziswa, Umthamo, Imiphumela Eceleni nokuningi

I-Etelcalcetide iyimithi esiza ukulawula amazinga e-calcium egazini lakho lapho amagciwane akho e-parathyroid engasebenzi kahle. Yenzelwe ngqo abantu abanesifo sezinso esingamahlalakhona abase-dialysis futhi abaye bathuthukisa isimo esibizwa ngokuthi i-secondary hyperparathyroidism. Cabanga ngayo njengomsizi omnene okhuluma ngamagciwane akho e-parathyroid ukuthi azole lapho esebenza kanzima kakhulu, okwenzeka kaningi lapho izinso zakho zingakwazi ukwenza umsebenzi wazo wokuhlunga udoti egazini lakho.

Yini i-Etelcalcetide?

I-Etelcalcetide iyimithi eyenziwe ngendlela yokufakelwa elingisa i-hormone yemvelo emzimbeni wakho ebizwa ngokuthi i-calcimimetic. Isebenza ngokubopha kuma-calcium-sensing receptors emagciwaneni akho e-parathyroid, okuyizindlala ezincane ezine entanyeni yakho ezisiza ukulawula amazinga e-calcium egazini lakho. Lapho lezi zindlala zizwa i-calcium eningi kunalokho ezikutholayo ngempela, zinciphisa ukukhiqizwa kwazo kwe-parathyroid hormone (PTH).

Le mithi ingeyeqembu lezidakamizwa ezibizwa ngokuthi ama-calcimimetics, futhi inikezwa ngokuqondile emgudwini wakho wegazi ngomugqa we-IV ngesikhathi sokwelashwa kwakho kwe-dialysis. Le mithi yaziwa nangegama layo lomkhiqizo elithi Parsabiv, futhi yakhelwe ngqo ukuthi isebenze kahle nenqubo ye-dialysis esivele isiza izinso zakho ukuthi zihlunga udoti emzimbeni wakho.

Isetshenziselwani i-Etelcalcetide?

I-Etelcalcetide isetshenziswa ikakhulukazi ukwelapha i-secondary hyperparathyroidism kubantu abadala abanesifo sezinso esingamahlalakhona abase-hemodialysis. I-Secondary hyperparathyroidism yenzeka lapho izinso zakho zingakwazi ukucubungula kahle i-vitamin D futhi zisuse i-phosphorus egazini lakho, okubangela ukuthi amagciwane akho e-parathyroid asebenze isikhathi esengeziwe ekukhiqizeni i-parathyroid hormone eningi kakhulu.
