6 Mavairasi Amene Amatsogolera Khansa

Matenda Ochepa Amakhala Opweteka

Palibe kachilombo kamene kamayambitsa khansara. Mavairasi asanu ndi limodzi omwe angayambitse khansara amachokera ku mabanja osiyanasiyana a mavairasi, amasiyana ndi ma genomes, ndipo amakhala ndi moyo wosiyana.

Kwachilendo, matendawa ali ndi mavairasi ambiri. Mwamwayi, ndi anthu ochepa okha omwe ali ndi kachilomboka kameneka amapitirizabe kukhala ndi khansa. Ndipo ngati khansa iyenera kukula, zingatenge zaka kapena makumi khumi kuti zigwire. Kuwonjezera apo, mavairasi okhawo sali okwanira kuti awonetse khansa komanso ayenera kuyendayenda ndi matenda osokoneza bongo, kusintha kwa thupi, kusintha kwa majeremusi, ndi kudwala khansa.

Nazi mitundu isanu ndi umodzi ya mavairasi omwe amachititsa khansara

Chiwindi cha chiwindi C

Hepatitis C ndi kachilombo ka RNA. Zimayambitsa matenda a chiwindi oopsa komanso aakulu. Matenda omwe ali ndi matenda a hepatitis C amachititsa chiwindi kapena chiwindi cha chiwindi. Pa 1 mpaka 2 peresenti ya anthu omwe ali ndi kachilomboka, matendawa amatha kutsogolera khansa ya hepatocellular (chiwindi). Matenda a Hepatitis C adagwirizananso ndi omwe si a Hodgkin's lymphoma .

Ngakhale kuti asayansi sapitirizabe katemera wa chiwindi cha C, mankhwala othetsera matendawa alipo, kuphatikizapo Olysio, Sovaldi, ndi Harvoni .

Hepatitis B

Ngakhale kuti hepatitis C ndi kachilombo ka RNA, matenda a chiwindi a B ndi DNA. Ngakhale kuti ali ndi kachilombo kosiyana, kachilomboka ka HIV kamayambitsa matenda odwala matenda a hepatitis C: matenda aakulu a chiwindi, matenda a chiwindi, ndi khansa ya hepatocellular.

Khansara ya hepatocellular ndi khansara yowopsa yomwe imapha chaka chimodzi kapena ziwiri pambuyo pa matenda. Chithandizo cha khansa ya hepatocellular chimatha pakutha opaleshoni resection ya chiwindi kapena kuika chiwindi.

Mwamwayi, tili ndi katemera wa chiwindi cha B.

Vuto la Papilloma ya Munthu (HPV)

HPV ndi kachilombo kakang'ono ka DNA komwe kamayambitsa ziwalo zogonana. Matenda omwe ali ndi kachilombo koyambitsa matenda a HPV angapangitse khansa ya pachibelekero. Komanso, matenda opatsirana a HPV akhala akuphatikizidwa pakukula kwa mitundu ina ya khansara, kuphatikizapo mimba ndi mutu, mapepala a khungu m'magulu osamalidwa bwino (amaganiza za Edzi), ndi khansa ya anogenital.

Mwamwayi, chifukwa cha kupuma kwa PAP, timakhala ndi machitidwe abwino kwambiri oyang'anira kansa ya pachibelekero.

Mtundu wa T Tymphocyte ya Munthu T (HTLV-1)

HTLV-1 ndi RNA retrovirus. Padziko lonse, anthu 5 mpaka 25 miliyoni ali ndi kachilombo ka HIV; Komabe, ochepa okha (5 peresenti) amakhala ndi zizindikiro. HTLV-1 ili ndi kutentha kapena kukopa kwa CD4 maselo, khungu la leukemia clonal cell. Zaka makumi awiri ndi makumi atatu kuchokera pamene matendawa ali ndi HTLV-1, akuluakulu a T-cell khansa ya m'magazi akhoza kuyamba.

Chemotherapy ikhoza kugwiritsidwa ntchito pochiza munthu wamkulu T-cell matenda a m'magazi ndipo imabweretsa kukhululukidwa kwa kanthawi kochepa komanso kutsatidwa mofulumira kwa matendawa. Kupulumuka (nthawi yapakati) nthawi pambuyo chitukuko cha akulu T-cell khansa ya m'magazi ndi miyezi isanu ndi umodzi.

Vuto la Epstein-Barr

EBV ndi kachilombo koyipa komwe timadziwa tonse-imayambitsa mononucleosis . Ngakhale kuti anthu 95 mwa anthu 100 alionse ali ndi EBV pa chikhalidwe cha mmero, matenda ambiri ndi ochepa kwambiri, ndi anthu ochepa omwe amapanga matenda a kuchipatala.

EBV imagwirizanitsidwa ndi mitundu yambiri ya khansa kuphatikizapo B-and T-cell lymphomas, leiomyosarcomas, nasopharyngeal carcinomas, matenda a Hodgkin, ndi matenda opatsirana pogwiritsa ntchito matendawa.

HHV-8 kapena Kaposi Sarcoma Herpesvirus

Mu 1994, HHV-8, kapena Kaposi sarcoma herpesvirus, adakhudzidwa ndi chitukuko cha Kaposi's sarcoma , khansara yomwe imayambitsa zilonda zam'mimba ndi zilonda kwa anthu omwe ali ndi AIDS. Komabe, mwa omwe ali ndi machitidwe amphamvu oteteza mthupi, HHV-8 ndi kawirikawiri yoipa.

Malangizo Otsogolera Akumbuyo kwa Mavairasi a Anthu Amtundu

Njira zatsopano zothandizira khansa zomwe zimayambitsa mavairasi aumunthu zimayang'ana mavitamini omwe amadziwika ndi maselo omwe amayamba ndi kachilomboka. Pofuna kulandira chithandizo chomwe chimayang'ana makamaka maselo omwe ali ndi kachilombo ka HIV, njira zothandizira zamtsogolo zikhoza kupulumutsa maselo a thanzi la thupi. Pakalipano, mankhwala monga chemotherapy ndi radiotherapy amapha maselo onse , omwe amafotokoza zotsatira zawo zoipa ndi zowawa.

Pakalipano, njira yabwino yothetsera khansa yowonjezera ndi mavairasi aumunthu (ngakhale kuti ndi osowa) ndikutetezera mavairasi aumunthu okha. Ngakhale ena mwa mavairasiwa ali otchuka, titha kupewa kuteteza mavairasi monga hepatitis B ndi C. Palinso katemera wa hepatitis B ndi HPV.
