Hyperammonemia: Nkag siab txog Kev Kho Mob Tseem Ceeb

Introduction

Hyperammonemia yog ib yam mob uas tshwm sim los ntawm kev nce qib ntawm ammonia hauv cov ntshav. Ammonia yog cov khoom siv los ntawm cov protein metabolism, thiab thaum lub cev feem ntau ua haujlwm thiab tshem tawm nws zoo, qee yam kev mob tuaj yeem ua rau nws tsub zuj zuj. Cov mob no tseem ceeb heev vim tias muaj cov tshuaj ammonia siab tuaj yeem ua rau muaj tshuaj lom, ua rau muaj teeb meem hauv lub paj hlwb thiab txawm tias tuag yog tias tsis kho tam sim ntawd. Kev nkag siab txog hyperammonemia, nws ua rau, cov tsos mob, kev kuaj mob, kev kho mob, thiab cov tswv yim tiv thaiv yog qhov tseem ceeb rau cov neeg mob thiab cov kws kho mob.

Lus txhais

Hyperammonemia yog dab tsi?

Hyperammonemia txhais tau tias yog qhov ntau tshaj ntawm ammonia hauv cov hlab ntsha, feem ntau ntsuas hauv micromoles ib liter (µmol / L). Cov qib ammonia ib txwm nyob hauv cov ntshav ntau ntawm 15 txog 45 μmol / L, thiab qib siab tshaj qhov no qhia tias hyperammonemia. Tus mob tuaj yeem mob hnyav lossis mob ntev, nyob ntawm qhov ua rau thiab lub sijhawm ntawm kev nce qib ammonia. Nws yog ib qho tseem ceeb kom paub tias hyperammonemia tsis yog ib yam kab mob ntawm nws tus kheej tab sis yog ib qho tsos mob ntawm ntau yam teeb meem kev noj qab haus huv.

Ua rau thiab Risk Factors

Kab mob/ib puag ncig ua rau

Qee yam kab mob tuaj yeem ua rau hyperammonemia, tshwj xeeb yog cov cuam tshuam rau lub siab, xws li kab mob siab lossis kab mob sepsis. Ib puag ncig yam tseem ceeb, xws li raug rau qee yam co toxins lossis tshuaj, tuaj yeem ua rau kom nce qib ammonia. Piv txwv li, qee cov tshuaj, tshwj xeeb tshaj yog cov uas cuam tshuam rau daim siab ua haujlwm, tuaj yeem ua rau lub cev tsis muaj peev xwm ua cov tshuaj ammonia.

Genetic/autoimmune ua rau

Cov kab mob caj ces yog ib qho tseem ceeb ua rau hyperammonemia. Urea cycle disorders (UCDs) yog cov xwm txheej qub txeeg qub teg uas cuam tshuam rau lub cev lub peev xwm hloov ammonia rau hauv urea, uas tom qab ntawd tawm hauv cov zis. Cov kab mob no tuaj yeem tshwm sim thaum menyuam mos lossis tom qab hauv lub neej, nyob ntawm seb hom tshwj xeeb. Cov kab mob autoimmune uas cuam tshuam rau daim siab ua haujlwm kuj tuaj yeem ua rau hyperammonemia.

Txoj kev ua neej thiab kev noj haus

Kev noj zaub mov tuaj yeem cuam tshuam rau qib ammonia. Kev noj zaub mov muaj protein ntau tuaj yeem ua rau muaj cov ammonia ntau ntxiv, tshwj xeeb tshaj yog rau cov tib neeg uas muaj lub siab ua haujlwm tsis zoo. Tsis tas li ntawd, kev haus cawv ntau dhau tuaj yeem ua rau lub siab puas tsuaj, ua rau nws muaj peev xwm ua cov tshuaj ammonia. Cov yam ntxwv ntawm kev ua neej xws li kev rog rog thiab kev coj cwj pwm tsis zoo kuj tuaj yeem ua rau muaj kab mob siab, ua rau muaj kev pheej hmoo ntawm hyperammonemia.

Yam Tseem Ceeb Risk

• Hnub nyoog: Cov me nyuam mos thiab cov me nyuam yaus muaj kev pheej hmoo siab dua vim lub siab tsis paub qab hau ua haujlwm thiab muaj peev xwm genetic ntshawv siab.
• Tub los ntxhais: Qee qhov kev tshawb fawb qhia tias cov txiv neej tuaj yeem raug mob rau qee yam kab mob siab uas tuaj yeem ua rau hyperammonemia.
• Qhov chaw Geographic: Tej thaj chaw tej zaum yuav muaj qhov tshwm sim ntau dua ntawm cov kab mob caj ces lossis kab mob sib kis uas cuam tshuam rau lub siab.
• Cov xwm txheej hauv qab: Cov tib neeg muaj kab mob siab, kab mob metabolic, lossis keeb kwm ntawm kev quav yeeb tshuaj yog qhov muaj feem pheej hmoo.

Cov tsos mob

Cov tsos mob ntawm Hyperammonemia

Cov tsos mob ntawm hyperammonemia tuaj yeem sib txawv, xws li mob me mus rau qhov hnyav. Cov tsos mob tshwm sim muaj xws li:
