Helicobacter pylori (HP) waa bakteeriyo ku nool caloosha oo ku dheggan xabka caloosha iyo meelaha bannaan ee unugyada dhexdooda, taasoo keenta caabuq.Caabuqa HP waa mid ka mid ah caabuqyada bakteeriyada ugu badan, oo gala balaayiin dad ah oo adduunka oo dhan ah.Waxay yihiin sababta ugu weyn ee boogaha iyo gastritis-ka (bararka xuubka caloosha).

Caabuqa sare ee carruurta iyo isku-darka qoyska ayaa ah sifooyinka muhiimka ah ee caabuqa HP-ga, gudbinta qoyskuna waxa ay noqon kartaa jidka ugu muhiimsan infekshanka HP waa sababta ugu weyn ee keenta gastritis-ka firfircoon ee daba-dheeraada, boog-calooleed, xuubka xuubka-xiniinyaha ee lymphoid unug (MALT) lymphoma, iyo kansarka caloosha.Sannadkii 1994-kii, Ururka Caafimaadka Adduunka/Hay'adda Caalamiga ah ee Cilmi-baarista Kansarka (WHO/IARC) waxay Helicobacter pylori u qoondaysay inay noqoto fasalka I kansarka.

Xuubabka caloosha - gaashaanka jirka ee caloosha

Xaaladaha caadiga ah, derbiga calooshu wuxuu leeyahay taxane ah hababka is-ilaalinta kaamil ah (dheecaanka acid gastric iyo protease, ilaalinta lakabyada xabka ee aan milmin iyo milmi lahayn, jimicsi joogto ah, iwm.), kuwaas oo iska caabin kara duulaanka kumanaan microorganisms. afka ka gala.

HP waxa uu leeyahay calan madax banaan iyo qaab dhismeed helical gaar ah, kaas oo aan kaliya ka ciyaarin door soojiidasho ah inta lagu jiro gumaysiga bakteeriyada, laakiin sidoo kale noqon karta mid wareegsan oo samaysa qaab-dhismeedka is-ilaalinta jawiga adag.Isla mar ahaantaana, Helicobacter pylori waxay soo saari kartaa noocyo kala duwan oo sun ah, taas oo go'aamisa in Helicobacter pylori ay ka gudbi karto lakabka casiirka gastric iyada oo adeegsanaysa awooddeeda oo ay iska caabiso aashitada gastric iyo waxyaabo kale oo aan fiicnayn, waxayna noqotaa microorganismka kaliya ee ku noolaan kara caloosha bini'aadamka. .

Cudurka loo yaqaan 'Helicobacter pylori'

1. Firfircoon

Daraasaduhu waxay muujiyeen in Helicobacter pylori ay leedahay awood xoog leh oo ay ku guurto jawi viscous ah, calanka calanka ayaa lagama maarmaan u ah bakteeriyada si ay ugu dabaasho lakabka xabka ee difaaca ee dusha sare ee xuubka caloosha.

2. Endotoxin-ku xidhan borotiinka A (CagA) iyo sunta vacuolar (VacA)

Cytotoxin-la-xidhiidha hidda-wadaha A (CagA) borotiinka ay siisay HP waxay kicin kartaa jawaab-celinta caabuqa gudaha.CagA-positive Helicobacter pylori infekshanku wuxuu sidoo kale si weyn u kordhin karaa halista gastritis atrophic, metaplasia xiidmaha iyo kansarka caloosha.

Vacuoating cytotoxin A (VacA) waa cunsur kale oo ugu muhiimsan cudurka Helicobacter pylori, kaas oo geli kara mitochondria si uu u habeeyo shaqada xubnaha jirka.

3. Flagellin

Laba borotiin oo flagellin ah, FlaA iyo FlaB, ayaa ka kooban qaybaha ugu waaweyn ee fiilooyinka calanka.Isbeddellada glycosylation flagellin waxay saameeyaan dhaqdhaqaaqa cadaadiska.Marka heerka glycosylation borotiinka FlaA la kordhiyey, awoodda socdaalka iyo culayska isticmaarku labadaba way korodhay.

4. Kaadi

Urease waxa ay dhalisaa NH3 iyo CO2 iyada oo la nadiifinayo urea, taas oo ka takhalusta aashitada gastric oo kor u qaada pH ee unugyada ku xeeran.Intaa waxaa dheer, urease wuxuu ka qaybqaataa jawaabaha bararka wuxuuna kor u qaadaa adhesion isagoo la falgalaya soo-qabayaasha CD74 ee unugyada epithelial gastric.

5. borotiinka shoogga kulaylka HSP60/GroEL

Helicobacter pylori waxay nuugtaa taxane borotiinno shoog kulayleed ah oo aad loo ilaaliyo, kuwaas oo isku muujinta Hsp60 ee urease ee E. koli ay si weyn u kordhiso dhaqdhaqaaqa kaadimareenka, taas oo u oggolaanaysa cudur-sidaha in uu la qabsado oo uu ku noolaado niche-ecoloji colaadeed ee caloosha bini'aadamka.

6. Protein-ku-xiran Hook-ku-xiran 2-homolog FliD

FliD waa borotiin qaabdhismeed ah oo ilaaliya caarada calanka oo si isdaba joog ah u gelin kara flagellin si ay u koraan fiilooyinka calanka.FliD waxa kale oo loo istcimaalaa molecule adhesion, oo aqoonsanaya glycosaminoglycan molecules ee unugyada martida loo yahay.Qolyaha cudurka qaba, unugyada difaaca jirka ka-hortagga ayaa calaamad u ah caabuqa waxaana loo isticmaali karaa ogaanshaha serological.

Hababka Imtixaanka:

1. Baaritaanka saxarada: Baaritaanka saxarada ee antigen-ka waa baaritaan aan fiicneyn oo loogu talagalay H.pylori.Qalliinku waa badbaado, fudud oo degdeg ah, oo uma baahna in afka laga maamulo wax reagen ah.

2. Serum antibody ogaanshaha: Marka infekshanka Helicobacter pylori uu ku dhaco jidhka, jidhka bini'aadamka wuxuu yeelan doonaa unugyada difaacayaasha Helicobacter pylori ee dhiigga sababtoo ah jawaab celinta difaaca.Adiga oo sawiraya dhiigga si loo eego xoogga-ururinta unugyada difaaca jirka ee Helicobacter pylori, waxay ka tarjumaysaa haddii uu jiro Helicobacter pylori jirka.caabuqa bakteeriyada.

3. Tijaabada neefta: Kani waa hab baadhis oo caan ah wakhtigan.Kaadi afka laga qaato oo ay ku jirto 13C ama 14C,iyo neefta waxay tijaabisaa uruurinta karbon ogsaydhsaydh ka kooban 13C ama 14C mudo kadib,maxaa yeelay hadii ay jirto Helicobacter pylori, urea waxaa lagu ogaanayaa ureadeeda gaarka ah.Enzymes-ku waxay u jajabaan ammonia iyo kaarboon-dioxide, kaas oo laga sii daayo sambabada iyada oo loo marayo dhiigga.

4. Endoscopy: waxay ogolaataa in si taxadar leh si taxadar leh loo eego astaamaha xabka caloosha sida casaanka, bararka, isbeddellada qanjidhada, iwm.;endoscopy kuma haboona bukaanada qaba dhibaatooyin daran ama diidmo iyo kharashyo dheeri ah ( suuxin, xoog) ).
