Yintoni iPyruvate Kinase Deficiency? Masithethe ngayo ngokulula!

Namhlanje siza kuthetha ngemeko yemfuza engaqhelekanga, kodwa ebaluleke kakhulu. Oku kubizwa ngokuba yi-'Pyruvate Kinase Deficiency'. Khawuthelekelele, kukho i-enzyme ekhethekileyo emzimbeni wethu enceda iiseli ezibomvu zegazi ukuba zenze amandla, kwaye ibizwa ngokuba yi-'Pyruvate Kinase'. Ngoko ke, xa kungekho le enzyme yaneleyo emzimbeni (oko kubizwa ngokuba yi-deficiency), ezo seli ezibomvu zegazi azinamandla okwenza umsebenzi wazo ngokufanelekileyo, kwaye ziqala ukuqhekeka ngokukhawuleza ngaphambi kokuba kuveliswe iiseli ezibomvu zegazi ezintsha.

Ezi seli zibomvu zegazi zithwala ioksijini emizimbeni yethu. Ngoko ke xa iiseli ezibomvu zegazi zincipha ngenxa yokunqongophala kwePyruvate Kinase, ezinye iiseli emzimbeni azifumani ioksijini eyaneleyo. Ngenxa yoko, unokuba neempawu ze-anemia. Le yimeko ekhoyo ukususela ekuzalweni kwaye ihlala ubomi bakho bonke. Oku kuthetha ukuba kuya kufuneka ube phantsi kweliso lengcali ye-hematologist ubomi bakho bonke. Nangona kunjalo, ezi mpawu zinokuhluka kumntu nomntu.

Ziziphi iimpawu zePyruvate Kinase Deficiency?

Iimpawu eziqhelekileyo ze-anemia kule meko zezi:

• Ukudinwa kakhulu: Oku kuthetha ukuziva udiniwe rhoqo, nokuba wenza into encinci.
• Ukubetha kwentliziyo: Ukuziva ngathi isifuba sakho siyabetha nangona umile nje.
• Ukuphefumla kancinci: Ukuva uphelelwa ngumphefumlo nokuba uqhuba kancinci.
• Ulusu oluphaphathekileyo: Xa umzimba ulahlekelwa ligazi, ulusu lutshintsha umbala, akunjalo?
• Ukudinwa: Ukuziva ngathi ujikeleza, ngamanye amaxesha ngathi uza kuwa.
• Intloko ebuhlungu : Iintloko ezibuhlungu rhoqo.

Ukongeza kwezi mpawu ze-anemia, ezinye iimpawu zinokuvela ngenxa yokuqokelelwa kwenkunkuma evela kwiiseli ezibomvu zegazi eziphukileyo emzimbeni. Masibone ukuba zeziphi:

• I-Jaundice: Ukutyheli kolusu kunye namhlophe emehlweni. Oku kubangelwa kukuqokelelana kwezinto ezibizwa ngokuba yi-bilirubin, ezivela kwiiseli ezibomvu zegazi eziqhekekileyo.
• I-spleen Ekhulisiweyo: I-spleen sisitho emzimbeni wethu esigcina iiseli ezibomvu zegazi eziphukileyo. Ngoko ke xa kukho umonakalo omkhulu kwiiseli, i-spleen inokukhula.
• Umchamo omnyama: Umchamo omnyama kunesiqhelo.

Iimpawu zihlala zibonakala xa zineminyaka emingaphi?

Nangona i-Pyruvate Kinase Deficiency (PK Deficiency) yimeko ekhoyo ekuzalweni, ixesha elithathayo ukuze iimpawu zibonakale lixhomekeke kubukhali bemeko yakho.

Khawucinge nje, ezinye iintsana ezisandul’ ukuzalwa zineempawu ezinzima kangangokuba zifuna unyango olusindisa ubomi ngokukhawuleza. Iintsana ezincinci zinokukhala kakhulu, zingavumi ukutya, kwaye ziyeke ukudlala. Abantwana abadala banokukhalaza ngokudinwa rhoqo kwaye baphelelwe ngumdla wokubaleka nokudlala. Abanye abantu abadala basenokungazi nokuba banale meko ide ibe yingxaki enkulu—umzekelo, ngexesha lokukhulelwa, usulelo olukhulu, okanye ukwenzakala.

Kutheni le nto isenzeka le `Pyruvate Kinase Deficiency`?

Esi sisifo semfuza esidluliselwa kwizizukulwana ngezizukulwana ngenxa yesiphene kwijini ebizwa ngokuba yi-`(PKLR)`. Cinga ngaso ngathi iijini zethu zifana nencwadi exelela iiseli zethu ukuba "yenza oku, yenza okuya". Ijini yakho ye-`(PKLR)` ixelela iiseli ezibomvu zegazi indlela yokwenza i-enzyme ebizwa ngokuba yi-`Pyruvate Kinase`. Le enzyme ye-`Pyruvate Kinase` inceda iiseli ezibomvu zegazi ukuba zenze i-`Adenosine Triphosphate` (ATP)`, umthombo wamandla.

Ngoko ke, kumntu one-'Pyruvate Kinase Deficiency' (PK Deficiency), ngenxa yesiphene kwi-'(PKLR)` gene, iiseli ezibomvu zegazi azikwazi ukuvelisa i-'Pyruvate Kinase` enzyme eyaneleyo. Ngenxa yoko, iiseli ezibomvu zegazi azikwazi ukuvelisa amandla `(ATP)` azidingayo ukuze ziphile. Ngenxa yoko, ezo seli ziyaqhekeka ngokukhawuleza. Emva koko inani leeseli ezibomvu zegazi emzimbeni liyancipha. Oku kubizwa ngokuba yi-'Hemolytic Anemia` , oko kuthetha i-anemia ebangelwa kukuqhekeka kweeseli ezibomvu zegazi.

Indlela ii-genes ezidluliselwa ngayo: `(Ilifa le-Autosomal Recessive)`

Ukuze uphuhlise i-'Pyruvate Kinase Deficiency' (i-PK Deficiency), kufuneka ufumane ii-genes ezimbini ezine-'PKLR' ezinesiphene . Enye ivela kumama wakho kwaye enye ivela kutata wakho. Oku kubizwa ngokuba yi-'Autosomal Recessive Inheritance' kwezonyango. Ukuze oku kwenzeke, bobabini abazali kufuneka babe ne-gene enye eqhelekileyo ye-'PKLR' kunye ne-gene enye ene-'PKLR' enesiphene. Nangona kunjalo, ngaphandle kokuba benze uvavanyo lwe-genetic, basenokungazi ukuba banale gene inesiphene okanye ukuba banokuyidlulisela ebantwaneni babo.

Kwabazali abanjalo, kukho ithuba elinye kwabane (25%) lokuba umntwana wabo uza kuzuza zombini ii-genes ezine-`(PKLR)` ezineephene kwaye abe ne-`Pyruvate Kinase Deficiency`.

Ngubani osengozini enkulu yokuba nale meko?

Ukunqongophala kwe-Pyruvate kinase (PK Deficiency) yimeko yemfuza edluliselwa kumzali ukuya emntwaneni, kwaye ixhaphake kakhulu kumaqela athile eentlanga. Ixhaphake kakhulu kubantu abazalwa kuMntla Yurophu. Ixhaphake kakhulu nakwezinye iindawo zama-Amish ePennsylvania nase-Ohio.

Ngaba ikho indlela yokunciphisa umngcipheko?

Asinakuyithintela imeko yemfuza ezuzwe njengelifa. Nangona kunjalo, ungavavanya umngcipheko wokuba nomntwana one-Pyruvate Kinase Deficiency. Ukuba wena okanye iqabane lakho ninembali yentsapho yale meko, kulungile ukuthetha nomcebisi wemfuza. Banokuchaza uvavanyo lwe-DNA olufumanekayo kwaye banokukunceda uqonde iziphumo ezinokubakho ngexesha lokukhulelwa.

Ziziphi iingxaki ezinokwenzeka ngenxa yale meko?
