PPD ndiyo bvunzo yekuyera kuongorora kuti huvepo hutachiona na Mycobacterium tibhii uye, nekudaro, kubatsira kuongororwa kwechirwere chetibhii. Kazhinji, bvunzo iyi inoitwa kune vanhu vanga vakanangana zvakananga nevarwere vakatapukirwa nehutachiona, kunyangwe kana vasingaratidze zviratidzo zvechirwere, nekuda kwekufungidzirwa kwehutachiona husingaoneki netibhii, apo hutachiona hwaiswa asi isati yakonzera chirwere. Tsvaga kuti chii zviratidzo zveTB.

Iyo PPD bvunzo, inozivikanwawo seye tuberculin bvunzo yeganda kana Mantoux reaction, inoitwa mumakiriniki ekuongorora marabhoritari kuburikidza nediki jekiseni rine mapuroteni akatorwa kubva kubhakitiriya riri pasi peganda, uye inofanirwa kuongororwa uye kududzirwa zviri nani nana pulmonologist kuti igone kunyatsoongorora.

Kana iyo PPD yakanaka pane mukana wakakura wekusvibiswa nehutachiona. Nekudaro, iyo PPD bvunzo yega haina kukwana kusimbisa kana kusabvisa chirwere, saka kana paine fungidziro yetibhii, chiremba anofanira kuraira kumwe kuyedzwa, senge chest X-rays kana sputum bacteria, semuenzaniso.

Maitirwo ebvunzo dzePPD

Iyo PPD bvunzo inoitwa mukiriniki yekuongorora rabhoritari kuburikidza jekiseni repuroteni rakanatswa rinobva (PPD), ndiko kuti, emapuroteni akacheneswa aripo pamusoro pehutachiona hwehutachiona. Mapuroteni anonatswa kuitira kuti chirwere chisamire muvanhu vasina hutachiona, zvisinei mapuroteni anoita kune vanhu vane hutachiona kana vakabayiwa jekiseni.

Chinhu chinoshandiswa paruoko rwekuruboshwe uye mhedzisiro yacho inofanirwa kuturikirwa maawa makumi manomwe nemaviri mushure mekuiswa, inova nguva inowanzoitika mhinduro. Nekudaro, mushure memazuva matatu mushure mekushandisa kweprotein yeprosesa, zvinokurudzirwa kudzokera kuna chiremba kuti uzive mhedzisiro yebvunzo, iyo inofanirwa zvakare kufunga nezvezviratidzo zvinoratidzwa nemunhu.

Kuti utore bvunzo dzePPD hazvidiwi kuti utsanye kana kutora imwe hanya, zvinokurudzirwa chete kuzivisa chiremba kana uri kushandisa chero mhando yemishonga.

Muedzo uyu unogona kuitirwa vana, vakadzi vane nhumbu kana vanhu vane hutachiona hwakakanganiswa, zvisinei, haufanire kuitwa kune vanhu vane mukana wekurwara zvakanyanya, senge necrosis, ulceration kana kukatyamadzwa kwakanyanya kweanaphylactic.

PPD bvunzo mhedzisiro

Mhedzisiro yeiyo PPD bvunzo inoenderana nesaizi yekuita paganda, sezvakaratidzwa mumufananidzo uye, nekudaro, inogona kuve:

• Kusvikira ku5mm: kazhinji, inoonekwa seyakaipa mhedzisiro uye, nekudaro, haina kuratidza hutachiona nehutachiona hwehutachiona, kunze kwemamwe mamiriro ezvinhu;
• 5 mm kusvika 9 mm: mhedzisiro yakanaka, inoratidza hutachiona nehutachiona hwehutachiona, kunyanya kuvana vari pasi pemakore gumi vasina kubayiwa kana kubayiwa BCG kweanopfuura makore maviri, vanhu vane hutachiwana hweHIV / AIDS, vasina hutachiona husina kusimba kana vane mavanga eTB pane radiograph. chifuva;
• 10 mm kana kupfuura: mhedzisiro, inoratidza hutachiona nehutachiona hwehutachiona.

Reaction size paPPD ganda

Mune mamwe mamiriro ezvinhu, kuvepo kwekuita kweganda kwakakura kupfuura mamirimita mashanu hazvireve kuti munhu atapukirwa ne mycobacterium inokonzera tibhii. Semuenzaniso, vanhu vakatove vakabayiwa jekiseni rekudzivirira tibhii (BCG jekiseni) kana vane hutachiona nemamwe marudzi emycobacteria, vanogona kusangana nekupindurwa kweganda panoitwa bvunzo, ichinzi mhedzisiro-yenhema

Mhedzisiro-isina mhedzisiro, iyo iyo munhu ane hutachiona nemabhakitiriya, asi asingaumbe mhinduro muPPD, inogona kumuka mune vanhu vane hutachiona husina simba, sevanhu vane AIDS, cancer kana kushandisa zvinodhaka zvinodzivirira, Kuwedzera kune kushaya zvinovaka muviri, zera rinopfuura makumi matanhatu nemashanu, kupera mvura mumuviri kana humwe hutachiona hwakanyanya

Nekuda kwemukana wemhedzisiro, tibhii haifanire kuongororwa nekuongorora bvunzo iyi yega. Iyo pulmonologist inofanirwa kukumbira mimwe bvunzo kuti isimbise kuongororwa, senge chest radiography, kuongororwa kwemajoni uye smear microscopy, inova bvunzo yerabhoritari umo sampuro yemurwere, kazhinji sputum, inoshandiswa kuona bacilli iyo inokonzera chirwere. Aya maedzo anofanirwa zvakare kurairwa kunyangwe iyo PPD isina kunaka, sezvo bvunzo iyi yega isingakwanise kushandiswa kusanganisa kuongororwa.
