Kuyini i-Homocystinuria (HCU)?
Kalula nje, (HCU) yisifo esingavamile sofuzo . Okwenzekayo kulokhu ukuthi umzimba wethu awukwazi ukulawula kahle i-amino acid (Homocysteine), okungukuthi, awukwazi ukuyisebenzisa nokuyisusa. Cabanga, kwenzekani uma izinto ezingenamsebenzi ziqoqana emzimbeni wethu? Kanjalo nje, le (Homocysteine) iqoqana ngokungadingekile egazini nasemchameni. Lokhu kuqoqana kungabangela izinkinga ezinkulu emehlweni, ohlelweni lwamathambo (uhlaka lwethu lwamathambo), ohlelweni lwezinzwa oluphakathi (ubuchopho nomgogodla), kanye nohlelo lwemithambo yegazi (imithambo yegazi). Manje unombuzo , ayini lawa ma-amino acid? Ama-amino acid ayizakhi eziyisisekelo zamaprotheni. Njengoba nje izitini zidingeka ukwakha isakhiwo, ama-amino acid ayadingeka ukwakha amaprotheni emzimbeni wethu. Umzimba wethu wenza ingxenye yale (Homocysteine) kwenye i-amino acid ebizwa ngokuthi (Methionine). Futhi, ekudleni okunamaphrotheni amaningi esikudlayo, isibonelo, inyama, inhlanzi, namaqanda, sithola (Methionine) eningi. Ngokuvamile, umzimba wethu uyayiphula le (Methionine) bese uyiguqula ibe (Homocysteine). Kodwa-ke, emzimbeni womuntu one-(Homocystinuria), i-enzyme edingekayo ukulawula kahle le (Homocysteine), okungukuthi, ukuyigcina isezingeni elidingekayo nokushintsha okunye, ayikho, noma ayisebenzi kahle. I-enzyme uhlobo lweprotheni olusheshisa ukusabela kwamakhemikhali emzimbeni wethu. Ngakho-ke uma le enzyme ingekho, izinga le-(Homocysteine) liyakhula.Yiziphi izinhlobo eziyinhloko ze-homocystinuria?
Abacwaningi bahlukanise i-homocystinuria ngezinhlobo eziningana ngokusekelwe ezimbangela zofuzo eziyisisekelo. Kunezinhlobo ezimbili eziyinhloko:1. Ukuntuleka kwe-Cystathionine beta-synthase (CBS) (i-Classical Homocystinuria)
Lolu uhlobo oluvame kakhulu lwe-homocystinuria. I-Cystathionine beta-synthase (CBS) iyi-enzyme esiza ukuguqula i-homocysteine ibe enye i-amino acid, i-cysteine. Lolu hlobo lwesifo lwenzeka lapho i-gene ye-CBS ikhiqiza i-enzyme ye-CBS encane kakhulu noma ingasebenzi nhlobo, noma lapho i-enzyme ye-CBS ingasebenzi kahle. I-enzyme ye-CBS idinga i-vitamin B6, eyaziwa nangokuthi i-pyridoxine, ukuze isebenze kahle. Lolu hlobo luhlukaniswe ngokwendlela osabela ngayo kahle ezithasiselweni ze-vitamin B6.2. Iphutha lokuguqulwa kwe-metabolism ye-Cobalamin (cbl)
Umzimba wethu udinga ukuguqula ingxenye ye-homocysteine ibe yi-methionine. Le nqubo ihilela i-vitamin B12, eyaziwa nangokuthi i-cobalamin. Umzimba wethu udlula ezinyathelweni eziningana ukuze uguqule i-homocysteine ibe yi-methionine. I-Homocystinuria, ebangelwa ukuntuleka kwe-cobalamin, yenzeka lapho umzimba ungakwazi ukuqeda lesi sinyathelo, ungenzi i-enzyme efanele, noma ukhiqiza ama-enzyme anephutha.

Check Availability →Uyini umehluko phakathi kwe-homocystinuria kanye ne-Marfan syndrome?
I-Marfan syndrome iyisifo esingavamile sofuzo esithinta izicubu ezixhumene emzimbeni wonke. Izimpawu eziningi zalesi sifo zifana neze-homocystinuria. Isibonelo, izitho ezinde, iminwe emide, emincane, i-ectopia lentis, kanye ne-myopia. Kodwa-ke, i-Marfan syndrome ibangelwa ukuguquka kwezakhi zofuzo ze-Fibrillin-1 (FBN1). Abantu abane-Marfan syndrome banamazinga ajwayelekile e -homocysteine ne-methionine.Ubani othinteka kakhulu yilesi simo? Sivame kangakanani?
I-Homocystinuria ibangelwa ukuguquka kwezakhi zofuzo. Ngakho-ke noma ubani angayithuthukisa. Kodwa-ke, ezinye izifundo zikhombisile ukuthi lesi simo sithinta abantu kwamanye amazwe kakhulu kunamanye. Lawa mazwe yilawa:- I-Ireland
- INorway
- IJalimane
- I-Qatar
Ziyini izimpawu ze-homocystinuria?
Izimpawu ze-(Homocystinuria) ziyahlukahluka kuye ngohlobo onalo. Ngokuvamile ziqala ukuvela eminyakeni embalwa yokuqala yokuphila. Kodwa-ke, abanye abantu bangase bangabi nazo izimpawu kuze kube yilapho sebekhulile. Uhlobo oluvame kakhulu lwe-(Homocystinuria) luvame ukuthinta lezi zinhlelo:- Amehlo
- Uhlelo lwamathambo
- Isistimu yezinzwa ephakathi
- Uhlelo lwemithambo yegazi
Izimpawu ezithinta amehlo:
- Ilensi yeso iyasuka endaweni yayo evamile (i-ectopia lentis). Lokhu kungabangela ukuphazamiseka kokubona .
- Ukubona okuphazamisekile kakhulu (i-myopia), okusho ukungakwazi ukubona kude.
Izimpawu ezithinta uhlelo lwamathambo:
- Kubonisa ukukhula ngokweqile .
- Ukwelulwa okungajwayelekile kwezingalo, imilenze, neminwe.
- Amadolo agobile ngaphakathi futhi amadolo ayashayisana uma imilenze iqondile (lokhu kubizwa nangokuthi "amadolo angqongqozayo").
- Isifuba sicwile ngaphakathi noma siphumele phambili.
- Ukugoba komgogodla (i-scoliosis).
- Abantu abane-homocystinuria nabo basengozini yokuthola i-osteoporosis .
Izimpawu ezithinta uhlelo lwezinzwa oluphakathi:
- Ukulibaziseka kokukhula . Lokhu kusho ukungabonakalisi intuthuko yengqondo noma yomzimba efanele iminyaka.
- Ubunzima bokufunda.
Izimpawu ezithinta uhlelo lwenhliziyo nemithambo yegazi:
- Ingozi eyengeziwe yokuqhekeka kwegazi. Lawa mahlule egazi angabangela izimo eziyingozi ezifana nesifo sohlangothi noma i-pulmonary embolism.
Yiziphi izimbangela ze-homocystinuria?
Izinhlobo eziningi ze-homocystinuria zibangelwa izinguquko zofuzo, noma izinguquko, ezizakhini zofuzo ezahlukahlukene.Izimbangela zofuzo
Uhlobo oluvame kakhulu lwe-(Homocystinuria) lubangelwa ukuguquka kwezakhi zofuzo ze-(CBS). Le (CBS) i-gene itshela umzimba wethu ukuthi ingayenza kanjani i-enzyme ebizwa ngokuthi (Cystathionine beta-synthase). Le enzyme inesibopho sendlela yamakhemikhali eguqula i-(Homocysteine) acid ibe yi-(Methionine). (Homocystinuria) ingabangelwa futhi ukuguquka kwezakhi zofuzo ze-(MTHFR), (MTR), (MTRR) kanye ne-(MMADHC). Zonke lezi zakhi zofuzo zinesibopho sokuguqula i-(Homocysteine) acid ibe yi-(Methionine). Uma noma yiliphi lala mazakhi zofuzo linokuguquka, i-enzyme efanele ayisebenzi kahle. Ngemuva kwalokho (Homocysteine) iqala ukuqongelela emzimbeni. Kodwa-ke, abacwaningi abakaqiniseki ngokuphelele ukuthi kungani amazinga aphezulu e-homocysteine abangela izimpawu ze-homocystinuria. Uzuza i-homocystinuria ngephethini ye-autosomal recessive. Lokhu kusho ukuthi uzozuza lesi sifo kuphela uma bobabili abazali bakho bemvelo, abavame ukungabi nazimpawu, bedlulisela kuwe isakhi sofuzo esithintekile.Ingabe i-homocystinuria ingabangelwa ukuntuleka kwamavithamini?
Yebo, i-homocystinuria ingabangelwa yizimbangela ezingezona ezezakhi zofuzo. Lesi simo singabangelwa nawukuntuleka okukhulu kwevithamini B6, ivithamini B9 (folate), noma ivithamini B12 (cobalamin).I-Homocystinuria itholakala kanjani?
Emazweni afana ne-United States, ukuhlolwa kokuhlolwa kwezinsana ezisanda kuzalwa kusetshenziselwa ukuhlola izimo eziningana ze-metabolic, okuhlanganisa ne-homocystinuria. Ukuhlolwa kwe-homocysteine kulinganisa amazinga e-homocysteine ne-methionine egazini lengane yakho. Uma imiphumela yokuhlolwa ilungile, okubonisa ukuthi lesi simo singase sibe khona, udokotela wengane yakho uzoyala ukuhlolwa okwengeziwe ukuqinisekisa imiphumela. Kodwa-ke, lokhu kuhlolwa kwezinsana ezisanda kuzalwa akulona njalo iqiniso elingu-100%. Ngezinye izikhathi kungase kungakwazi ukuthola izimo ezithile. Ngakho-ke, abanye abantu batholakala bene-homocystinuria ngemva kokuvela kwezimpawu. Nakuba izimpawu eziningi zivela ebuntwaneni noma ebuntwaneni, ngezinye izikhathi zingavela ebudaleni. Uma unezimpawu ze-(Homocystinuria), udokotela wakho uzoyala i-(Homocysteinuria test) ukuqinisekisa lesi simo. Uma imiphumela ikhombisa ukuthi une-(classical homocystinuria) (okungukuthi, (CBS) yokushoda), udokotela wakho uzoyala olunye ukuhlolwa ukuthola ukuthi yiluphi uhlobo onalo. Lokhu kubizwa ngokuthi (inselele ye-vitamin B6) . Lokhu kuhlolwa kuthola ukuthi usabela kanjani ezithasiselweni ze-vitamin B6. Udokotela wakho angabe esekwakhela uhlelo lokwelashwa olufanele. (Classical homocystinuria) ingahlukaniswa kanje:- Isabela ku-Vitamin B6: Umzimba wakho wenza i-enzyme eyanele (CBS)'', ngakho-ke i-vitamin B6 ingasiza leyo enzyme ukuthi isebenze kahle.
- Isabela kancane ku -vitamin B6: Umzimba wakho wenza inani elithile le-enzyme (CBS)'', ngakho-ke i-vitamin B6 ingasiza kancane.
- I-Vitamin B6-engaphenduli: Umzimba wakho awukhiqizi ngokwanele i-enzyme (CBS)'', ngakho-ke i-vitamin B6 cishe ayizukusiza i-enzyme.
Yiziphi izindlela zokwelapha i-homocystinuria?
Ukwelashwa kwe-homocystinuria kuhilela ukulawula amazinga e-homocysteine egazini lakho nokulawula izimpawu zakho. Ukwelashwa kuvame ukufaka phakathi ukuthatha izithasiselo ze-vitamin B6. Uma unohlobo oluphendula ku-vitamin B6 (i-homocystinuria yakudala), izithasiselo ze-vitamin B6 zingase zanele ukwehlisa nokulawula amazinga akho e-homocysteine. Kodwa-ke, uma unohlobo olungaphenduli noma oluphendula kancane ku-vitamin B6 (i-homocystinuria yakudala), izithasiselo ze-vitamin B6 zodwa zingase zinganeli. Ungadinga ezinye izindlela zokwelapha. Lokhu kungafaka:- Umuthi (Betaine) (Betaine) noma (Cystadane): (Betaine) usiza ukunciphisa izinga ( Homocysteine ) egazini lakho.
- Ukudla okukhethekile kwe-(Homocystinuria): Kuzodingeka ulandele ukudla okuvimbela ukudla okuqukethe amaprotheni kanye ne-(Methionine).
- Izithasiselo ezengeziwe: Uma unesinye uhlobo lwe-homocystinuria, kungadingeka futhi ukuthi uthathe izithasiselo ze-folate ( i-vitamin B9 ) noma i-cobalamin ( i-vitamin B12 ).
Into ebaluleke kakhulu ukuthi lokhu kwelashwa kufanele kuqhubeke impilo yakho yonke . Yilapho kuphela lapho ungalawula khona amazinga akho e-homocysteine , unciphise izinkinga, futhi uphile impilo enempilo.
Ungaphila isikhathi esingakanani ne-homocystinuria?
Uma kutholakale kusenesikhathi futhi kwelashwa kahle impilo yonke, izingane eziningi ezine-Homocystinuria zingalindela ukuphila impilo evamile nenempilo . Ngakho-ke, ukuxilongwa kusenesikhathi kanye nokwelashwa okuqhubekayo kubaluleke kakhulu.Ingabe i-homocystinuria ingavinjelwa?
Ngenxa yokuthi kuyisimo sofuzo, i-homocystinuria ayinakuvinjelwa. Kodwa-ke, uma ukhulelwe noma uhlela ukuba nomntwana esikhathini esizayo, kufanelekile ukukhuluma nomeluleki wezakhi zofuzo. Ukwelulekwa ngezakhi zofuzo kungakusiza uqonde ingozi yakho yokuba nomntwana one-homocystinuria. Kuvamile ukuzizwa ukhungathekile lapho uthola ukuthi wena noma ingane yakho ninesimo sofuzo. Zinike isikhathi sokufunda konke ongakwenza nge-homocystinuria. Bese, thola udokotela oqonda ngokugcwele isimo sakho. Ukusebenza nochwepheshe we-metabolic kungakunikeza umuzwa wokulawula. Ngokuzinika amandla ngolwazi nezinsiza, ungafinyelela umphumela omuhle kakhulu.Okokugcina, into ebaluleke kakhulu (Umyalezo Wokuya Ekhaya)
Kulungile, ngakho-ke ngithemba ukuthi usuyaqonda kangcono lokho ebesikhuluma ngakho (i-Homocystinuria). Nazi ezinye izinto ezibalulekile okufanele uzikhumbule:- Kuyini (Homocystinuria)?Isifo esingavamile, kodwa esingaba yingozi ngokwezakhi zofuzo.
- Okwenzekayo kulokhu ukuthi umzimba awukwazi ukulawula kahle ikhemikhali ebizwa ngokuthi i-Homocysteine,'' bese iqoqana emzimbeni.
- Lokhu kungabangela izinkinga emehlweni, emathanjeni, ohlelweni lwezinzwa kanye nasemithanjeni yegazi .
- Into ebaluleke kakhulu ukuqaphela lesi sifo kusenesikhathi bese uthola ukwelashwa okufanele impilo yakho yonke . Uma wenza lokho, ungaphila impilo evamile.
