Yintoni uVavanyo lweWidal?

Ukubaluleka koVavanyo lweWidal

Uvavanyo lweWidal ludlala indima ebalulekileyo:

• Ukuxilongwa Kwangoko kweTyphoid kunye neParatyphoid Fever: Kubalulekile ekuchongeni olu sulelo kwimimandla apho luxhaphake khona, luvumela ungenelelo ngexesha elifanelekileyo.
• Ukwahlula usulelo oluSebenzayo olusuka kuMtyhilelo odlulileyo: Ngokulinganisa amanqanaba e-antibody, uvavanyo lunceda ukwahlula phakathi kosulelo lwangoku kunye nokuvezwa kwangaphambili kwi-Salmonella.
• Izigqibo zonyango oluKhokelayo: Iziphumo ezichanekileyo zinceda ababoneleli bezempilo ekukhetheni unyango olufanelekileyo, ukunciphisa umngcipheko weengxaki kunye nokuthintela ukusasazeka kwesi sifo.

Uvavanyo lweWidal lusetyenziselwa ntoni?

Uvavanyo lwe-Widal lusetyenziselwa ukuxilongwa kwe-enteric fever, ebangelwa ikakhulu yi-Salmonella Typhi kunye ne-Salmonella Paratyphi. Idlala indima ebalulekileyo:

• Ukuxilonga iTyphoid kunye neParatyphoid Fever: Uvavanyo lwe-Widal lunceda ekuqinisekiseni ukusuleleka kweTypoid kunye neParatyphoid kubantu ababonakalisa iimpawu, ukuqinisekisa ukungenelela ngexesha kunye nonyango.
• UkuBeka iliso kokuqhambuka: Kwiindawo ezinococeko olubi, uvavanyo lwe-Widal luyimfuneko ekulandeleni ukuqhambuka, ukuncedisa kwiinzame zempilo yoluntu.
• Ukuphonononga Amatyala arhanelwayo: Kwiimeko ezisikelwe umda apho iindlela zokuxilonga ezikumgangatho ophezulu zinokungafumaneki, uvavanyo lwe-Widal lubalulekile ekuvavanyeni iimeko ezikrokrelekayo zomkhuhlane we-enteric kunye nokunceda ekuthatheni isigqibo seklinikhi.

Ukulungiselela uVavanyo

Akukho malungiselelo athile afunekayo kuvavanyo lwe-Widal. Nangona kunjalo:

• Yazisa ugqirha wakho malunga naziphi na izifo eziqhubekayo okanye amayeza, njengoko anokuchaphazela iziphumo.
• Isampulu yegazi enye idla ngokwanela uvavanyo.

Widal Test Procedure

Uvavanyo lwegazi lweWidal lubandakanya la manyathelo alandelayo:

• Ukuqokelelwa kweSampule seGazi: Uchwepheshe wezempilo uya kutsala inani elincinci legazi elivela kwi-vein engalweni, ngokuqhelekileyo kwinkqubo ekhawulezayo nelula.
• Uhlalutyo lweLebhu: Isampulu yegazi iye ihlalutywe elabhoratri ukubona ubukho kunye namanqanaba e-antibodies ngokuchasene ne-O kunye ne-H antigens ye-Salmonella.
• Ukutolika: Iziphumo zichazwe njenge-antibody titers, ezibonisa ukuxinwa kwezilwa-buhlungu ezithile egazini, ezinceda ukufumanisa ukuba usulelo luyasebenza na.

Le nkqubo ithe ngqo, ayiphazamisi, kwaye ihlala ithatha imizuzu embalwa ukuyigqiba.

Widal Test Uluhlu oluqhelekileyo

Uvavanyo lwe-Widal lubonisa i-antibody titers eziqhelekileyo ze-Salmonella Typhi kunye ne-Salmonella Paratyphi antigens phakathi kolu luhlu lulandelayo: Kwi-O (somatic) antigen, i-titers eziqhelekileyo ziphakathi kwe-1:40 kunye ne-1:80. Ngokufanayo, kwi-antigen ye-H (flagellar), uluhlu oluqhelekileyo lukwayi-1:40 ukuya ku-1:80. Ezi xabiso zibonisa ukungabikho kosulelo lwamva nje okanye olusebenzayo. I-Titers engaphezulu kwe-1: i-160 nokuba i-antigen ingabonisa ukusuleleka okusebenzayo okunokwenzeka, kunye nokunyuka okukhulu kwemilinganiselo ye-titer ukusuka kwisampuli yokuqala ukuya kweyesibini eqokelelwe kwiiveki ezi-1-2 kamva kuthathwa njengesiphakamiso sokusuleleka ngokuqhubekayo.

Utoliko lweziphumo zovavanyo lweWidal

Ukutolikwa kweziphumo zovavanyo lwe-Widal kuxhomekeke kumanqanaba e-titer ye-antibodies ngokuchasene ne-Salmonella Typhi kunye ne-Salmonella Paratyphi antigens, kunye nobukho beempawu. Ngezantsi yindlela iziphumo ezitolikwa ngayo ngokubanzi:

• Amanqaku aphantsi (1:40 ukuya ku-1:80): Ngokuqhelekileyo bonisa ukuba akukho usulelo lwamva nje okanye olusebenzayo. Ezi ziphumo zinokucebisa ukuvezwa kwangaphambili okanye ukungakhuseleki kwendalo kodwa azihambelani nosulelo olusebenzayo, ngakumbi ngokungabikho kweempawu.
• Amagama aPhakamileyo (Ngaphezu kwe-1:160): Cebisa ukusuleleka okunokwenzeka okusebenzayo kunye ne-Salmonella Typhi okanye i-Salmonella Paratyphi, ngakumbi xa zombini i-O kunye ne-H antigen titers ziphakanyisiwe.
• Ukwandiswa okuphindwe kane kwiiSampulu ezidityanisiweyo: Ukunyuka okuphindwe kane kwii-antibody titers phakathi kweesampulu ezimbini ezithathwe kwi-1-2 yeeveki ezihlukeneyo kubonisa ngamandla usulelo olusebenzayo.
• Ukuqwalaselwa kweempawu zeklinikhi: Uvavanyo lwe-Widal kufuneka lutolikwe kunye neempawu zeklinikhi, njengoko iziphumo ezingeyonyani okanye izinto ezingalunganga zinokwenzeka, ngakumbi kwimimandla enesifo okanye kunye nokuvezwa kwangaphambili kwe-Salmonella.

Izinto ezichaphazela iziphumo zovavanyo lwe-Widal

Izinto ezininzi zinokuchaphazela ukuchaneka kunye nokutolika kweziphumo zovavanyo lweWidal:

• Ugonyo lwangaphambili: Abantu abaye bagonyelwa i-typhoid fever banokubonisa i-antibody titers ephakamileyo, nokuba lungekho usulelo olusebenzayo.
• Usulelo oludlulileyo: Imbali yosulelo lwangaphambili lwe-Salmonella inokukhokelela kwii-antibodies eziqhubekayo kwigazi, ezinokuthi zibangele iimpawu zobuxoki.
• Ukuphinda usebenze kwakhona: Uvavanyo lwe-Widal lunokuvelisa iziphumo ezingeyonyani ukuba izilwa-buhlungu zidibana nezinye iibhaktheriya ezibangela iimpawu ezifanayo, njengeentlobo ezithile zosulelo lwe-enteric.
• Ixesha loVavanyo: Kwangethuba losulelo, amanqanaba e-antibody anokuba phantsi kakhulu ukuba angabonwa. Uvavanyo oluphindayo emva kweeveki ezi-1 ukuya kwezi-2 lunokuba yimfuneko ukuxilongwa ngokuchanekileyo, ngakumbi ukuba iimpawu ziyaqhubeka.

Uvavanyo olulungileyo lweWidal

Uvavanyo oluqinisekileyo lwe-Widal lubonisa ubukho be-antibodies ngokuchasene ne-Salmonella Typhi okanye i-Salmonella Paratyphi, ebonisa usulelo olusebenzayo, olufana ne-typhoid okanye i-paratyphoid fever. Uvavanyo lulinganisa amanqanaba e-antigens kwi-O (somatic) kunye ne-H (flagellar) yale bhaktheriya egazini.

• Widal Test Positive Report: Xa ingxelo yovavanyo lwe-Widal ilungile, ibonisa i-antibody titers ephakamileyo, ngokwesiqhelo okanye ngaphezulu kwe-1:160. Oku kubonisa ukuba umzimba usabela ngokusebenzayo kusulelo. Kwezinye iimeko, iisampulu zegazi ezidityanisiweyo ziyavavanywa ukuze kubonwe ukonyuka okuphindwe kane kwi-antibody titers, enokuqinisekisa ngakumbi ubukho bosulelo olusebenzayo.
• Uvavanyo olubanzi lwemilinganiselo emihle: Ezi titer ze-antibody zilandelayo zibonisa iziphumo ezilungileyo:
  • O antigen titers ≥ 1:160
  • H antigen titers ≥ 1:160

Ezi titers ziphakamileyo zibonisa ukuba umntu ukhe wachanabeka kwi-Salmonella okanye okwangoku ulwa nosulelo, olufana ne-typhoid okanye i-paratyphoid fever.

• Widal Test Positive Treatment: Ekuqinisekiseni usulelo olusebenzayo ngovavanyo olulungileyo lwe-Widal, unyango lwangexesha lokubulala iintsholongwane lubalulekile. Unyango oluqhelekileyo luquka:
  • I-Ciprofloxacin: Kumatyala anzima.
  • Ceftriaxone: Kusulelo oluqatha okanye iimeko ezifuna unyango ngomthambo.
  • I-Azithromycin: Kusulelo olungephi okanye xa ezinye izibulala-ntsholongwane zisenokungafaneleki.

Ukongeza kwii-antibiotics, ukunakekelwa kwenkxaso, njengokugcina i-hydration kunye nokulawula umkhuhlane, kubalulekile ekubuyiseleni isigulane.

Kubalulekile ukutolika uvavanyo lwe-Widal iziphumo ezinethemba kunye neempawu zeklinikhi, njengoko kunokubakho iziphumo ezingezizo, ngakumbi kubantu abanogonyo lwangaphambili okanye usulelo lwe-Salmonella lwangaphambili.
