Groundbreaking TB ndi DR-TB Diagnostic Solution yolembedwa ndi #Macro & Micro -Test!

Chida Chatsopano Chozindikiritsa Chifuwa cha TB ndi Kuzindikira Kulimbana ndi Mankhwala: Kutsata Kutsata Kwachibadwidwe Chatsopano (tNGS) Kuphatikizidwa ndi Kuphunzira Kwamakina kwa Matenda a TB Hypersensitivity Diagnosis

Lipoti la Literature: CCa: njira yodziwira matenda yozikidwa pa tNGS ndi kuphunzira makina, yomwe ili yoyenera kwa anthu omwe ali ndi chifuwa chachikulu cha bakiteriya komanso chifuwa chachikulu cha TB.

Mutu wa phunziroli: Tsatanetsatane wa m'badwo wotsatira wotsata TB ndi kuphunzira pamakina: njira yowunikira kwambiri ya paucific pulmonary tubulars ndi tubular meningitis.

Kuphatikizidwa ndi University of Chinese Academy of Sciences ndi Beijing Chest Hospital of Capital Medical University, Macro & Micro-Test adakhazikitsa njira yodziwira matenda a chifuwa chachikulu kutengera ukadaulo watsopano waukadaulo wotsatizana (tNGS) ndi njira yophunzirira makina, yomwe imapereka kwambiri kuzindikira kukhudzidwa kwa chifuwa chachikulu cha TB chokhala ndi mabakiteriya ochepa ndi chifuwa chachikulu cha TB, chinapereka njira yatsopano yodziwira matenda a hypersensitivity kwa matenda a mitundu iwiri ya chifuwa chachikulu cha TB, ndikuthandizira kuzindikira molondola, kuzindikira kukana mankhwala ndi kuchiza chifuwa chachikulu.Nthawi yomweyo, zimapezeka kuti cfDNA ya plasma ya wodwalayo ingagwiritsidwe ntchito ngati mtundu woyenera wa zitsanzo zachipatala pakuzindikira kwa TBM.

Pakafukufukuyu, zitsanzo za 227 za plasma ndi cerebrospinal fluid zamadzimadzi zidagwiritsidwa ntchito kukhazikitsa magulu awiri azachipatala, momwe ma laboratory diagnostic cohort cohort adagwiritsidwa ntchito kuti akhazikitse makina ophunzirira matenda a chifuwa chachikulu cha TB, ndipo zitsanzo zachipatala zidagwiritsidwa ntchito kutsimikizira zomwe zidakhazikitsidwa. matenda chitsanzo.Zitsanzo zonse zidayang'aniridwa ndi dziwe lomwe linapangidwa mwapadera la Mycobacterium TB.Kenaka, pogwiritsa ntchito ndondomeko ya TB-tNGS, chitsanzo cha mtengo wa chigamulo chimagwiritsidwa ntchito popanga maulendo a 5 pamagulu ophunzitsira ndi ovomerezeka a mzere wofufuza ma laboratory, ndipo zizindikiro zowunikira zitsanzo za plasma ndi cerebrospinal fluid zitsanzo zimapezeka.Malo omwe apezeka amabweretsedwa m'mayesero awiri a mzere wozindikira matenda kuti azindikire, ndipo magwiridwe antchito a wophunzira amawunikidwa ndi ROC curve.Potsirizira pake, chitsanzo cha matenda a chifuwa chachikulu chinapezedwa.

Kuyamba mwachidule kwa zinthu zozindikira za chifuwa chachikulu cha Macro & Micro-Test

Poganizira zovuta za zitsanzo za odwala chifuwa chachikulu ndi zosowa zosiyanasiyana, Macro & Micro-Test imapereka njira zonse za NGS zochotsa madzi kuchokera ku zitsanzo za sputum, kumanga laibulale ya Qualcomm ndi kutsatizana, ndi kusanthula deta.The mankhwala kuphimba matenda mofulumira TB odwala, mankhwala kukana kuzindikira chifuwa chachikulu, kulemba mycobacterium chifuwa chachikulu ndi NTM, hypersensitivity matenda a bakiteriya alibe chifuwa chachikulu ndi anthu chifuwa chachikulu, etc.

Chiyambi cha malonda

Mankhwalawa amachokera ku mankhwala akuluakulu a mzere woyamba ndi wachiwiri wofotokozedwa mu malangizo a chithandizo cha WHO TB, macrolides ndi aminoglycosides omwe amagwiritsidwa ntchito kwambiri mu malangizo a mankhwala a NTM, ndipo malo otsutsana ndi mankhwala amaphimba gulu limodzi la malo okhudzana ndi kukana mankhwala. Bungwe la WHO Mycobacterium tuberculosis complex mutation mutation catalogue, komanso jini zina zotsutsana ndi mankhwala komanso malo osinthika malinga ndi kafukufuku ndi ziwerengero zamabuku opambana kwambiri kunyumba ndi kunja.

Chizindikiritso cha kulemba chimachokera ku zovuta za NTM zomwe zafotokozedwa mwachidule mu malangizo a NTM ofalitsidwa ndi Chinese Journal of Tuberculosis and Respiratory Diseases ndi mgwirizano wa akatswiri.Zoyambira zolembera zomwe zidapangidwa zimatha kukulitsa, kutsatizana ndikutanthauzira mitundu yopitilira 190 ya NTM.

Kupyolera mu ukadaulo waukadaulo wokulitsa wa PCR wokhazikika, jini za genotyping ndi majini osamva mankhwala a Mycobacterium adakulitsidwa ndi multiplex PCR, ndipo kuphatikiza kwa amplicon kwamitundu yomwe mukufuna kuzindikirika idapezedwa.Zogulitsa zowonjezera zimatha kumangidwa mumalaibulale amtundu wachiwiri kapena wachitatu, ndipo nsanja zonse zotsatizana za m'badwo wachiwiri ndi wachitatu zimatha kutsatiridwa mozama kwambiri kuti mupeze zambiri zotsatizana zamitundu yomwe mukufuna.Poyerekeza ndi masinthidwe odziwika omwe ali m'malo osungira omwe adamangidwa (kuphatikiza kabuku ka WHO Mycobacterium tuberculosis complex mutation ndi ubale wake ndi kukana mankhwala), masinthidwe okhudzana ndi kukana mankhwala kapena kutengeka kwa mankhwala othana ndi chifuwa chachikulu adatsimikiziridwa.Kuphatikizidwa ndi njira yodzitsegulira yokha ya sputum ya Macro & Micro-Test, vuto la kuchepa kwa nucleic acid amplification ya zitsanzo za sputum (kuchuluka kwa khumi kuposa njira zachikale) linathetsedwa, kotero kuti kuzindikira kusagwirizana ndi mankhwala kungathe kuzindikirika. amagwiritsidwa ntchito mwachindunji ku zitsanzo za sputum zachipatala.
