Isifo seLambert-Eaton - Iyeza
Isifo seLambert-Eaton - Iyeza

I-Lambert-Eaton syndrome (i-LES) sisifo esinqabileyo apho unxibelelwano oluphosakeleyo phakathi kwemithambo kunye nezihlunu lukhokelela kubuthathaka bemisipha.

I-LES kukuphazamiseka komzimba. Oku kuthetha ukuba amajoni akho omzimba ajonge ngempazamo iiseli kunye nezicubu emzimbeni. Nge-LES, ii-antibodies eziveliswa ngamajoni omzimba ahlasela iiseli zemithambo-luvo. Oku kwenza iiseli zemithambo-luvo zingakwazi ukukhupha ngokwaneleyo imichiza ebizwa ngokuba yi-acetylcholine. Le khemikhali ihambisa iimvakalelo phakathi kwemithambo-luvo kunye nezihlunu. Isiphumo kukuba buthathaka kwezihlunu.

I-LES inokuthi ivele ngomhlaza njengomhlaza omncinci wesifo somhlaza okanye ukuphazamiseka komzimba njenge-vitiligo, ekhokelela ekulahlekelweni ngumbala wesikhumba.

I-LES ichaphazela amadoda rhoqo kunabafazi. Ubudala obuqhelekileyo bokwenzeka kweminyaka engama-60. I-LES inqabile ebantwaneni.

Ubuthathaka okanye ukuphulukana nentshukumo enokuba ngaphezulu okanye ngaphantsi kakhulu, kubandakanya:

  • Kunzima ukunyuka izinyuko, ukuhamba, okanye ukuphakamisa izinto
  • Intlungu yezihlunu
  • Ukujongwa kwentloko
  • Isidingo sokusebenzisa izandla ukuvuka kwindawo ehleliyo okanye eleleyo
  • Iingxaki ukuthetha
  • Iingxaki zokuhlafuna okanye ukugwinya, ezinokubandakanya ukugxothwa okanye ukukrwitshwa
  • Umbono utshintsha, njengombono ongacacanga, umbono ophindwe kabini, kunye nengxaki yokugcina ujongano oluzinzileyo

Ubuthathaka ngokubanzi buthathaka kwi-LES. Imisipha yomlenze ichaphazeleka kakhulu. Ubuthathaka bunokuphucuka emva kokuzilolonga, kodwa ukuzingisa okuqhubekayo kubangela ukudinwa kwezinye iimeko.


Iimpawu ezinxulumene namanye amalungu enkqubo ye-neva zihlala zenzeka, kwaye zibandakanya:

  • Uxinzelelo lwegazi luyatshintsha
  • Ukuba nesiyezi xa umi
  • Umlomo owomileyo
  • Ukungasebenzi kakuhle kwe-Erectile
  • Amehlo omileyo
  • Ukuqunjelwa
  • Ukwehla kokubila

Umboneleli wezempilo uya kwenza uvavanyo lomzimba kwaye abuze malunga neempawu. Uviwo lunokubonisa:

  • Ukuhla kwengqondo
  • Ukuphulukana okunokwenzeka kwezihlunu zemisipha
  • Ubuthathaka okanye ukukhubazeka okuba ngcono kancinci kunye nomsebenzi

Uvavanyo lokunceda ukufumanisa isifo kunye nokuqinisekisa i-LES inokubandakanya:

  • Uvavanyo lwegazi ukukhangela izilwa-buhlungu ezihlasela imithambo-luvo
  • I-Electromyography (EMG) yokuvavanya impilo yemicu yemisipha
  • Ukuhamba kwesantya (NCV) ukuvavanya isantya sombane kunye ne-nerves

Ukuvavanywa kwe-CT kunye neMRI yesifuba kunye nesisu, kulandele i-bronchoscopy yabantu abatshayayo kunokwenziwa ngaphandle komhlaza. Ukuskena i-PET kungenziwa kwakhona ukuba kurhanelwa ithumba lemiphunga.


Iinjongo eziphambili zonyango kukuba:

  • Chonga kwaye uphathe naziphi na iingxaki ezinje, njengomhlaza wemiphunga
  • Nika unyango ukunceda ngobuthathaka

Ukutshintshiselana ngePlasma, okanye iplasmapheresis, lunyango olunceda ukususa emzimbeni naziphi na iiproteni ezinobungozi (ii-antibodies) eziphazamisa ukusebenza kwentliziyo. Oku kubandakanya ukususa i-plasma yegazi enee-antibodies. Ezinye iiproteni (ezinjengealbumin) okanye iplasma enikelweyo emva koko ifakwe emzimbeni.

Enye inkqubo ibandakanya ukusebenzisa i-intravenous immunoglobulin (IVIg) ukufaka isixa esikhulu sezinto zokulwa ngqo egazini.

Amayeza anokuzama kwakhona aquka:

  • Iziyobisi ezicinezela impendulo yenkqubo yomzimba yokuzikhusela
  • Amachiza e-anticholinesterase ukuphucula ithoni yemisipha (nangona ezi zingasebenzi kakuhle xa zinikwa zodwa)
  • Iziyobisi ezonyusa ukukhutshwa kwe-acetylcholine kwiiseli zemithambo-luvo

Iimpawu ze-LES zinokuphucula ngokunyanga isifo esingaphantsi, ukucinezela amajoni omzimba, okanye ukususa ii-antibodies. Nangona kunjalo, i-paraneoplastic LES ayinakuphendula ngokunjalo kunyango. (Iimpawu ze-Paraneoplastic LES zibangelwa kukutshintsha kwenkqubo yomzimba yokuzikhusela kwisisu). Ukufa kubangelwa sisifo esibi.


Iingxaki ze-LES zingabandakanya:

  • Ubunzima bokuphefumla, kubandakanya ukusilela kokuphefumla (okuqhelekileyo)
  • Kunzima ukugwinya
  • Usulelo, njenge-pneumonia
  • Ukulimala kokuwa kunye neengxaki ngokulungelelanisa

Shayela umnikezeli wakho ukuba iimpawu ze-LES zikhula.
