Uvavanyo lwe-ASLO: yazi ukuba yeyantoni

Umxholo

• Yenzelwe ntoni
• Kwenziwa njani

Uvavanyo lwe-ASLO, ekwabizwa ngokuba yi-ASO, AEO okanye anti-streptolysin O, ijolise ekuchongeni ubukho betyhefu ekhutshwe yintsholongwane. IStreptococcus pyogenes, iStreptolysin O. Ukuba usulelo lweli bhaktiriya aluchongwanga lunyangwe ngamayeza okubulala iintsholongwane, umntu lowo angakhula abe neengxaki ezithile, ezifana ne-glomerulonephritis kunye ne-rheumatic fever, umzekelo.

Olona phawu luphambili losulelo kule ntsholongwane ngumqala obuhlungu obenzeka ngaphezulu kwamaxesha ama-3 ngonyaka kwaye oku kuthatha ixesha ukusombulula. Ukongeza, ukuba ngaba zikhona ezinye iimpawu ezinje ngokuphefumla kancinci, iintlungu esifubeni okanye iintlungu ezidibeneyo kunye nokudumba, kubalulekile ukufuna unyango, kuba kunokuba yimeko ye-rheumatic fever. Yazi ukuba yintoni i-rheumatism egazini.

Uvavanyo kufuneka lwenziwe kwisisu esingenalutho kangangeeyure ezi-4 ukuya kwezi-8, kuxhomekeke kwisindululo sikagqirha okanye elebhu, kwaye iziphumo zihlala zikhutshwa emva kweeyure ezingama-24.

Yenzelwe ntoni

Ugqirha uhlala eyalela uvavanyo lwe-ASLO xa umntu eneziqendu zomqala obuhlungu ukongeza kwiimpawu ezinokubonisa umkhuhlane wamathambo, onje:

• Ifiva;
• Khohlela;
• Ukuphefumla okufutshane;
• Iintlungu ezidibeneyo kunye nokudumba;
• Ubukho bamaqhuqhuva phantsi kolusu;
• Ubukho bamabala abomvu eluswini;
• Iintlungu zesifuba.

Ke, ngokusekwe kuhlalutyo lweempawu kunye nesiphumo sovavanyo, ugqirha uya kuba nakho ukuqinisekisa ukuxilongwa kwe-rheumatic fever, umzekelo, obonakala ngoxinzelelo oluphezulu lwe-anti-streptolysin O egazini. Qonda indlela yokuchonga nokunyanga isifo samathambo.

I-Streptolysin O yityhefu eveliswe yintsholongwane efana ne-streptococcus-like, the IStreptococcus pyogenes, ethi, ukuba ayichongwanga okanye inyangwe ngamayeza okubulala iintsholongwane, inokubangela i-rheumatic fever, i-glomerulonephritis, i-scarlet fever kunye ne-tonsillitis, umzekelo. Ke, ezona ndlela ziphambili zokuchonga usulelo kule ntsholongwane kukusuka ekuchongweni kwale tyhefu ngokufunyanwa kweentsholongwane eziveliswa ngumzimba ngokuchasene nebhaktiriya, eyi-anti-streptolysin O.

Nangona iziphumo ezintle luphawu losulelo ngu IStreptococcus pyogenes, ayingabo bonke abantu abaphuhlisa iimpawu ze-rheumatic fever, i-glomerulonephritis okanye i-tonsillitis, umzekelo, nangona kunjalo kufuneka babekwe iliso ngugqirha, benze uvavanyo lwegazi ngamaxesha athile kunye nokuhlolwa kwentliziyo. Jonga ukuba zeziphi iimvavanyo eziceliweyo ukuvavanya intliziyo.

Kwenziwa njani

Uvavanyo lwe-ASLO kufuneka lwenziwe esiswini esingenanto kangangeeyure ezi-4 ukuya kwezi-8, ngokwesindululo sonyango okanye elebhu kwaye kwenziwa ngokuqokelela isampulu yegazi ethunyelwa elebhu ukuba ihlolwe. Kwilabhoratri, kuvavanyo kwenziwa ukuze kufunyanwe ubukho be-anti-streptolysin O egazini, oko kwenziwa ngokudibanisa i-20µL ye-reagent, ebizwa ngokuba yiLatex ASO, ukuya kwi-20µL yesampulu yesigulana kwisitya esimnyama esingasemva. Emva koko, i-homogenization yenziwa imizuzu emi-2 kwaye amasuntswana ajongiwe ukuze aqokeleleke kwisitya.

Iziphumo kuthiwa azibi xa uxinizelelo lwe-anti-streptolysin O lilingana okanye lingaphantsi kwama-200 IU / mL, kodwa esi siphumo singahluka ngokwelabhoratri ekwenziwe kuyo uvavanyo kunye nobudala bomntu. Ukuba kufunyenwe i-agglutination, isiphumo kuthiwa sihle, kwaye kuyafuneka ukuba wenze izilungiso ezilandelelanayo ukujonga uxinzelelo lwe-anti-streptolysin O egazini. Kule meko, ugqirha unokucela uvavanyo olutsha emva kweentsuku ezili-10 ukuya kwezi-15 ukujonga ukuba uxinzelelo lwe-anti-streptolysin luyancipha egazini, luhlala luhleli okanye luyanda, kwaye ke ukujonga ukuba usulelo luyasebenza okanye alusebenzi.

Ukongeza kuvavanyo lwe-ASLO, ugqirha unokucela inkcubeko ye-microbiological yezinto ezivela emqaleni, njengoko yindawo apho ibhaktheriya ihlala ikhona, ukubona ngokuthe ngqo ubukho bentsholongwane IStreptococcus pyogenes.
