Iyini i-MEN-1? Izimpawu, Izimbangela, Nokwelapha

I-Multiple Endocrine Neoplasia Type 1 (i-MEN-1) iyisimo esingavamile sezofuzo esenza ukuba kube khona izicubu ezikhula ezindlini eziningi ezikhiqiza ama-hormone emzimbeni wakho. Lezi zicubu zivame ukuba zilungile, okusho ukuthi azina-kansa, kodwa zingasathinta indlela umzimba wakho okhiqiza futhi usebenzisa ngayo ama-hormone.

Cabanga ngesistimu yakho ye-endocrine njengenethiwekhi yemilayezo yomzimba wakho, enezihlahla ezikhulula ama-hormone ukulawula konke kusukela ekushukwini kwegazi kuya ekuqineni kwama-bone. Uma une-MEN-1, lenethiwekhi ingaba nezinto eziyisikrini eziyephula ukukhiqizwa kwama-hormone okuvamile, okuholela ezimpawu ezihlukahlukene ezingase zibonakale zingahlobene ekuqaleni.

Iyini i-MEN-1?

I-MEN-1 iyisifo sezofuzo esithinta ikakhulu izindawo ezintathu eziyinhloko zomzimba wakho: amagciwane e-parathyroid entanyeni yakho, i-pancreas, ne-pituitary gland ebuchosheni bakho. Lesi simo sithola igama lawo ngoba sihilela amagciwane amaningi e-endocrine akhula ngokungavamile, okuyigama lezokwelapha lokukhula kwezicubu ezingavamile.

Lesi simo sithinta abantu abacishe babe ngu-1 ku-30,000, okwenza kube yinto engavamile. Okwenza i-MEN-1 ibe nzima ngokukhethekile ukuthi ingabangela izimpawu ezihlukahlukene kubantu abahlukahlukene, ngisho nasemhlabeni omnyama.

Izicubu ezihlobene ne-MEN-1 zikhula kancane ngokuhamba kwesikhathi. Nakuba eziningi zilungile, zingasabangela izinkinga ezinkulu zezempilo ngokukhiqiza okuningi kwama-hormone athile noma ngokukhula okukhulu ngokwanele ukucindezela izitho eziseduze.

Ziyini izimpawu ze-MEN-1?

Izimpawu ze-MEN-1 zingase zihluke kakhulu ngoba ziyahluka kuye ngokuthi yiziphi izitho ezihlobene nokuthi zikhiqiza kangakanani i-hormone. Abantu abaningi abazi ukuthi bane-MEN-1 kuze kube yilapho sebekhulu, njengoba izimpawu zivame ukukhula kancane ngokuhamba kweminyaka.

Njengoba i-MEN-1 ithinta amagciwane akho e-parathyroid ngokuvamile, ungase uqale ubone izimpawu ezihlobene namanani aphezulu e-calcium egazini lakho:

• Amatshe ezinso aqhubeka ebuya
• Ubuhlungu lwamathambo noma ukweqile okuzenzakalelayo
• Ukukhathala okungapheli ngisho nalapho ukhululekile
• Ukudideka noma ukuguquka kwesimo sengqondo
• Ubuthakathaka bemisipha
• Ukumomotheka okukhulu nokuphazamiseka kokumisa
• Ukuphefumula noma ukuphazamiseka kwesisu
• Izinkinga zokukhumbula noma ukudideka

Uma i-MEN-1 ithinta i-pancreas yakho, ungase ube nezimpawu ezihlobene nokungalingani kwama-hormone lapho. Uma izicubu ezikhiqiza i-insulin zikhula, ungase ube nezingxenye zeshukela egazini eliphansi kakhulu ngezimpawu ezinjengokwehla, ukuzamazama, ukushaya kwenhliziyo okusheshayo, noma ngisho nokuwohloka.

Abanye abantu bakhula izicubu ezikhiqiza i-gastrin, i-hormone ekhuphula i-acid yesisu. Lokhu kungabangela ama-ulcers esiswini abukhali, ukushisa kwesisu okuqhubekayo, ukweluka, noma ubuhlungu besisu obungaphenduli kahle ekwelapheni okuvamile.

Uma i-pituitary gland ihilelekile, ungase ubone izimpawu ezinjengokukhathazeka okuqhubekayo, ukuguquka kokubona, noma izinkinga zokukhula nokukhula kobulili. Abanye abantu baba nezikhathi zokutholakala ezingavamile, ukunciphisa i-sex drive, noma ukukhiqizwa okungalindelekile kobisi emazinini.

Ezimweni ezingavamile, i-MEN-1 ingathinta ezinye izingxenye zomzimba wakho, ibangela ukukhula kwesikhumba, izicubu zephunga, noma izicubu ezindlini zakho ze-adrenal. Lezi zinkinga azivamile kodwa zingase zenzeke njengoba isimo siqhubeka.

Yini ebangela i-MEN-1?

I-MEN-1 ibangelwa yizinguquko ku-MEN1 gene, evame ukusiza ukuvimbela izicubu ekubeni zikhule ezindlini zakho ze-endocrine. Uma le gene ingasebenzi kahle, amaseli kulezi zihlahla angakhula ngokungapheli, akha izicubu ezibonakala kuleli simo.

Lolu shintsho lwezofuzo luzuzwe kulokho odokotela abakubiza ngokuthi iphethini ebusayo ye-autosomal. Lokhu kusho ukuthi udinga kuphela ukudlulisela ikhophi elilodwa le-gene eguqukile kumzali oyedwa ukuze uthole i-MEN-1. Uma omunye wabazali bakho enei-MEN-1, unethuba elingu-50% lokudlulisela lesi simo.

Cishe ku-10% yezimo, i-MEN-1 ivela njengenguquko entsha, okusho ukuthi akukho mzali onalesi simo. Lezi zimo zibizwa ngokuthi i-de novo mutations, futhi zenzeka ngokungahleliwe phakathi kokwakheka kwamaseli okuzala noma ekuthuthukiseni kwasekuqaleni.

I-MEN1 gene ikhiqiza i-protein ebizwa ngokuthi i-menin, esebenza njengomlindi emaseleni akho. I-menin iyasiza ukulawula ukwahlukaniswa kwamaseli futhi ivimbela amaseli ekukhuleni ngokushesha kakhulu. Uma i-gene yonakele, le ndlela yokuvimbela ihluleka, ivumela ukukhula kwezicubu ezicubungulweni ezikhiqiza ama-hormone.

Nini okufanele ubona udokotela nge-MEN-1?

Kufanele uxhumane nodokotela wakho uma uhlushwa amatshe ezinso aqhubekayo, ikakhulu uma usencane noma uma ebuya ngisho nalapho uthole ukwelashwa. Amatshe ezinso avamile ahlangene nezinkinga zamathambo noma ukukhathala okuqhubekayo kungase kubonise inkinga ngamagciwane akho e-parathyroid.

Funani ukunakekelwa kwezokwelapha uma unezingxenye zokwehla, ukuzamazama, ukushaya kwenhliziyo okusheshayo, noma ukudideka okungase kubonise ukwehla okubi kakhulu kweshukela egazini. Lezi zimpawu, ikakhulu uma zenzeka uma ungadli, zidinga ukuhlolwa ngokushesha.

Hlela i-aphoyintimenti uma uthola ama-ulcers esiswini angapheli ngokwelashwa okuvamile, noma uma une-heartburn ehlala njalo kanye nokweluka nobuhlungu besisu. Lo mhlanganiso wezimpawu ungase ubonise izicubu ezikhiqiza ama-hormone e-pancreas yakho.

Xhumana nodokotela wakho uma uhlushwa ukukhathazeka okuqhubekayo kanye nokuguquka kokubona, njengoba lokhu kungase kubonise i-pituitary tumor. Ngokufanayo, uma uqaphela ukuguquka okungalindelekile ezikhathini zakho zokutholakala, i-sex drive, noma ukukhiqizwa kobisi emazinini, lezi zingase zibe izimpawu zokubandakanyeka kwe-pituitary.

Uma unomlando womndeni we-MEN-1 noma izimo ezihlobene, kubalulekile ukuxoxa ngokuhlolwa kwezofuzo nokukhethwa nodokotela wakho, ngisho noma ungenawo izimpawu. Ukutholwa kwasekuqaleni kungasiza ukuvimbela izinkinga futhi kuqondise ukulandelela okufanele.

Ziyini izimbangela ze-MEN-1?

Imbangela eyinhloko ye-MEN-1 ukuba nomzali onalesi simo. Njengoba i-MEN-1 ilandela iphethini yokudluliselwa kwe-autosomal ebusayo, abantwana babazali abahlushwa yilesi simo banethuba elingu-50% lokudlulisela inguquko yezofuzo.

Ukuba nomlando womndeni wezicubu ezingavamile ezihlobene nama-hormone, ngisho noma zingakaqondwa njenge-MEN-1, kungase kukhulise ingozi yakho. Ngezinye izikhathi lesi simo asiqondwa emindenini iminyaka eminingi, ikakhulu uma izimpawu zingezinkulu noma zibhekwa njengezimbangela ezihlukile.

Ngokungafani nezinye izimo eziningi, i-MEN-1 ayinazimbangela ezihlobene nendlela yokuphila. Ukudla kwakho, imikhuba yokuzivocavoca, ukukhishwa komkhathi, noma izinqumo zakho siqu azithinti ukuthi uzokuthola yini lesi simo sezofuzo.

Ubudala bungathinta ukuthi izimpawu zivele nini, kodwa abushintshi ingozi yakho yokuba nalesi simo. Abantu abaningi abane-MEN-1 bathuthukisa izimpawu phakathi kweminyaka engu-20 no-40, nakuba abanye bangase bangabonisi izimpawu kuze kube kamuva ekuphileni noma, ngokungavamile, ngesikhathi sobuntwana.

Ubulili abuthinti kakhulu ingozi yakho yokudlulisela i-MEN-1, nakuba ezinye izimpawu zingase zivele ngokuhlukile kubantu besilisa nabesifazane ngenxa yezingxenye ze-hormone.

Ziyini izinkinga ezingase zenzeke nge-MEN-1?

Izinkinga ze-MEN-1 zingaba zinkulu futhi zivame ukuphathelene nemiphumela yokuhlala isikhathi eside yokungalingani kwama-hormone noma ukuba khona kwezicubu ezikhula. Ukuqonda lezi zinkinga ezingase zenzeke kusiza wena neqembu lakho lokunakekelwa kwezempilo ukuba niqaphele izinkinga.

Amanani aphezulu e-calcium avela emagciwaneni e-parathyroid asebenza kakhulu angabangela izinkinga eziningana ezinkulu:

• I-osteoporosis ebuhlungu kakhulu nokukhula kengozi yokweqile
• I-Chronic kidney disease evela ematshe ezinso aqhubekayo
• Izinkinga zokushaya kwenhliziyo ezivela ekungalingani kwe-calcium
• Ukudideka okukhulu noma ukuphazamiseka kokukhumbula
• Ama-ulcers esiswini angase aphule noma agqeme

Izicubu ze-pancreatic zingabangela ukwehla okubulalayo kweshukela egazini okungase kuholele ekubanjweni kwezifo, ukungazi lutho, noma ukonakala okungapheli kobuchopho uma kungelaphiwe ngokushesha. Ezinye izicubu ze-pancreatic zikhiqiza i-gastrin eningi kakhulu, okuholela kuma-ulcers abukhali angase aphule isisu noma i-intestine.

Izicubu ze-pituitary zikhula ngokwanele ukucindezela izakhiwo eziseduze, okungase kubangele ukulahleka kokubona okungapheli noma ukushoda kwama-hormone okukhulu.
