Etiology

Lub ntsiab lus ntawm tus kab mob qhia nws cov tshuaj lom-ua xua etiology. Qhov no txhais li cas? Cov txheej txheem o tawm tsam keeb kwm yav dhau los ntawm kev ua xua ua rau lub cev puas tsuaj los ntawm co toxins. Muaj ib qho detachment ntawm txheej txheej ntawm daim tawv nqaij nrog ntxiv necrosis.

Tus mob no suav hais tias yog hom kab mob bullous dermatitis. Lub npe tom qab tus kws kho mob Lyell, uas tau piav qhia thawj zaug hauv xyoo 1956 yog ib hom mob toxicoderma loj heev. Daim duab kho mob tuaj yeem muab piv nrog daim tawv nqaij kub ntawm 2nd degree. Lwm lub npe rau tus mob yog "malignant pemphigus".

Nrog rau kev poob siab anaphylactic, tus kab mob no suav hais tias yog qhov ua xua loj tshaj plaws. ThiabNws yuav tsum tau muab sau tseg tias nyob rau hauv tas li ntawd mus rau qhov no pathology tuag, muaj lwm yam kab mob me ntsis zoo ib yam li nws, uas yog hu ua Stevens-Johnson syndrome (abbreviated li SJS). Lawv feem ntau tsis meej pem, tab sis nws yog nyob ntawm cov kws tshaj lij paub txog cov kab mob no.

Causes of Lyell's syndrome

Qee qhov paub txog kab mob yog tshwm sim los ntawm kev tsis haum tshuaj rau cov tshuaj. Qhov laj thawj tshaj plaws yog sulfonamides. Tsawg zaus - tetracycline tshuaj tua kab mob, erythromycins, tshuaj tiv thaiv kab mob, qee cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv kab mob. Kuj tseem muaj cov xwm txheej sib cais ntawm ib tus neeg tsis haum rau kev noj zaub mov, kev npaj cov vitamin, nrog rau cov kab mob tetanus toxoid thiab radiopaque agents.

Raws li lwm pab pawg neeg mob, kev cuam tshuam rau cov txheej txheem sib kis, feem ntau tshwm sim los ntawm pawg II Staphylococcus aureus, tuaj yeem paub qhov txawv. Xws li kev ua xua hnyav (Lyell's syndrome, tsis yog Johnson's) feem ntau pom thaum yau thiab muaj kev kawm hnyav heev.

Muaj ntau tus neeg mob idiopathic, cov laj thawj uas tseem tsis tau paub.

Kev txhim kho ntawm tus mob no kuj tau pom thaum kho mob hnyav ntawm ntau yam pathologies. Muaj kev xav tias nws yog ib qho kev sib xyaw ua ke, kis kab mob thiab tshuaj, uas yog qhov ua rau muaj tus kab mob no.

Pathogenesis

Cov kab mob piav qhia nws tus kheej sai sai: los ntawm ob peb teev mus rau 1 lub lis piam. Muaj cov xwm txheej ntawm nws txoj kev loj hlob hauvtom qab hnub tim.

Nws feem ntau lees txais tias qhov tshwm sim ntawm Lyell's syndrome yog provoked los ntawm ib tus neeg muaj kev tsis haum tshuaj ntawm lub cev, uas yog qhov kev txiav txim ntawm caj ces. Nws yog hom tshuaj tsis haum tshuaj hnyav.

Lub anamnesis ntawm ntau tus neeg mob muaj qhov ua xua xws li mob rhinitis, quav nyab ua npaws, tiv tauj dermatitis, eczema, bronchial hawb pob, thiab lwm yam.

Mechanism rau kev txhim kho cov tshuaj tiv thaiv kab txawv

Lyell's syndrome tshwm sim li cas hauv cov menyuam yaus? Cov txheej txheem ntawm detoxification ntawm cov khoom metabolic cuam tshuam hauv lub cev. Yog li, cov tshuaj sib xyaw nrog cov protein uas yog ib feem ntawm cov txheej txheem ntawm daim tawv nqaij. Yog li ntawd, ib qho khoom txawv teb chaws yog tsim nyob rau hauv cov qauv ntawm lub tom kawg, uas ib qho kev tiv thaiv kab mob tshwm sim tom qab. Nws hloov tawm tias daim tawv nqaij nws tus kheej dhau los ua qhov muaj zog tshaj allergen. Qhov no tuaj yeem sib npaug nrog cov kev cuam tshuam ntawm lub cev mus rau kev hloov pauv txawv teb chaws. Tsuas yog hauv qhov no, tsis muaj dab tsi txawv txawv.

Ntxim qab kawg, txhua tus neeg mob uas muaj Lyell thiab Johnson syndromes yog tus cwj pwm los ntawm kev muaj cov tshuaj tiv thaiv kab mob hauv lub cev, hu ua Schwartzman-Sanarelli tshwm sim.

Kev cuam tshuam hauv lub cev

Nyob rau hauv lub cev, cov txheej txheem ntawm chains ntawm cov tshuaj protein thiab cov kev cai ntawm lawv lwj yog cuam tshuam. Qhov no tau tshwm sim hauv lawv qhov kev tswj tsis tau thiab kev tawg sai heev, vim tias lawv khaws cia hauv lub cev (hauv nws cov kua), uas ua rau muaj kev cuam tshuam rau cov kabmob hauv nruab nrog cev.

Txhua yam no ua rau lub cev ua haujlwm ntawm lub cev lawv tus kheej, uas yog lub luag haujlwm raupov tseg ntawm cov khoom lwj thiab lawv tshem tawm kuj raug kev txom nyem heev. Yog li ntawd, qhov sib npaug ntawm dej-ntsev hauv lub cev raug cuam tshuam, nrog rau qhov sib npaug ntawm cov zaub mov.

Kev tuag hauv Lyell's syndrome yog qhov siab heev.

Cov tsos mob thiab kev kuaj mob

Tus kab mob no feem ntau cuam tshuam rau cov hluas thiab menyuam yaus. Kev kuaj mob feem ntau yog ib qho yooj yim raws li cov tsos mob thiab kev kuaj pom yooj yim pom tseeb hauv qhov no.

Saum toj no peb tau sau tseg tias tus kab mob no tshwm sim los ntawm kev txhim kho hauv lub sijhawm luv luv. Tus mob deteriorates sharply, tus neeg mob tej zaum yuav txawm tuag ua ntej pib ntawm kev kho mob. Nws tag nrho pib nrog qhov kub thiab txias, qee zaum mus rau qhov tseem ceeb, lub cev yog npog nrog cov pob liab liab nyob rau hauv daim ntawv ntawm cov pob liab liab nrog me me edema. Kev kuaj mob Lyell's syndrome yuav tsum tau ua sai sai.

Nyob rau hauv qhov loj
