Izindlela Zokuxilonga Umkhuhlane We-Dengue
I-Pendahuluan
Umkhuhlane wegazi we-dengue (DHF) yisifo esibangelwa yigciwane esidluliselwa ngokulunywa omiyane be-Aedes aegypti kanye ne-Aedes albopictus. Igciwane le-dengue elibangela i-DHF liqukethe izinhlobo ezine: i-DENV-1, i-DENV-2, i-DENV-3, kanye ne-DENV-4. Lesi sifo siyinkinga enkulu yezempilo emazweni amaningi asezindaweni ezishisayo nezishisayo, okuhlanganisa ne-Indonesia. Ngakho-ke, izindlela zokuxilonga ezisheshayo nezinembile zibalulekile ekutholeni nasekuphatheni lesi sifo. Lesi sihloko sizobuyekeza izindlela ezahlukene zokuxilonga ezisetshenziswa ukuthola umkhuhlane wegazi we-dengue.
Ukubonakaliswa Kwemitholampilo Komkhuhlane We-Dengue
Ngaphambi kokuxoxa ngezindlela zokuxilonga, kubalulekile ukuqonda izimpawu zomtholampilo zomkhuhlane we-dengue. Izimpawu zomkhuhlane we-dengue zivame ukuvela ngemva kwesikhathi sokufukamela sezinsuku ezingu-4-10 ngemva kokulunywa umiyane. Izimpawu zokuqala zifaka phakathi umkhuhlane omkhulu ngokuzumayo, ikhanda elibuhlungu, ubuhlungu ngemuva kwamehlo, ubuhlungu bemisipha namalunga, isicanucanu, ukuhlanza, kanye nokuqubuka kwesikhumba. Ezimweni ezimbi kakhulu, lesi sifo singaqhubekela ekubeni umkhuhlane we-dengue ohambisana nokopha okuzenzekelayo kanye ne-dengue shock syndrome, okungaba yingozi empilweni.
Izindlela Zokuxilonga
1. Ukuxilongwa Kwezokwelapha
Indlela yokuqala evame ukusetshenziswa ukuxilongwa kwezokwelapha . Lokhu kuhlonza kusekelwe ezimpawini ezijwayelekile zomkhuhlane we-dengue eziboniswa yisiguli. Ekuqaleni, udokotela uzokwenza umlando nokuhlolwa ngokomzimba ukuze athole izimpawu ezifana nomkhuhlane ophezulu, ubuhlungu bamalunga, ukuqubuka, nezinye izimpawu zakudala. Kodwa-ke, lokhu kuhlonza kwezokwelapha kuvame ukuba yinto eqondene nomuntu futhi kungabi nokucacisa, okudinga ukuqinisekiswa ngokuhlolwa kwelebhu.
2. Ukuhlolwa kwe-Hematology
Ezigulini ezine-dengue fever, imingcele ethile ye-hematological ikhombisa izinguquko ezinkulu. Inani lama-platelet lingenye yezivivinyo ze-hematological ezibaluleke kakhulu. I-Thrombocytopenia (inani lama-platelet elinciphile) iyisibonakaliso esivamile ezigulini ezine-dengue fever. Ngaphezu kwalokho, i-leukopenia (inani lamaseli amhlophe egazi elinciphile) kanye nokugcwala kwegazi (ukwanda kwe-hematocrit) nakho kungase kwenzeke.
3. Ukuhlolwa kwe-Serology
Ukuhlolwa kwe-serology kusetshenziselwa ukuthola ukuthi kukhona ama-antibodies akhiqizwa ngumzimba ekuphenduleni ukutheleleka ngegciwane le-dengue . Izindlela ezimbili eziyinhloko zokuhlola i-serology yilezi:
– I-IgM kanye ne-IgG ELISA: I-Enzyme-Linked Immunosorbent Assay (ELISA) iyindlela evame ukusetshenziswa ukuthola ama-antibodies e-IgM kanye ne-IgG egazini lesiguli. I-IgM ivame ukuvela ezinsukwini ezingu-3-5 ngemva kokuqala kwezimpawu bese inyamalala zingakapheli izinyanga ezimbalwa, kuyilapho i-IgG ivele kamuva futhi ingaqhubeka impilo yonke. Ukutholwa kwe-IgM kubonisa ukutheleleka okukhulu kwe-dengue, kuyilapho i-IgG ibonisa ukutheleleka kwangaphambilini noma okuphindaphindiwe.
– Ukuhlolwa Okusheshayo Kokuxilonga (ama-RDT): Lokhu kuhlolwa okusheshayo okusekelwe ku-immunochromatography kuvumela ukutholakala okusheshayo nokulula kwama-antibodies e-IgM kanye ne-IgG. Nakuba kungazweli kakhulu futhi kuqondile kune-ELISA, ama-RDT avame ukusetshenziswa ensimini noma ezindaweni ezinezindawo zelebhu ezilinganiselwe.
4. Ukutholwa Kwe-Antigen ye-NS1
I-NS1 (i-Non-Structural Protein 1) iyiprotheni ekhiqizwa yigciwane le-dengue ngesikhathi sokutheleleka okukhulu futhi ingatholakala egazini lesiguli kusukela ngosuku lokuqala lwezimpawu. Ukuthola i-NS1 antigen usebenzisa i-NS1 antigen rapid test kit noma i-ELISA kunganikeza ukuxilongwa kusenesikhathi ngaphambi kokuba kuvele ama-antibodies e-IgM. Le ndlela inikeza inzuzo yokutholakala kusenesikhathi kanye nokuphathwa okusheshayo kweziguli ezinomkhuhlane we-dengue.
5. Ukusabela Kwe-Reverse Transcription-Polymerase Chain (RT-PCR)
I-RT-PCR iyindlela yama-molecule ebucayi kakhulu futhi eqondile yokuthola izakhi zofuzo zegciwane le-dengue. Le nqubo ihilela ukuguqula i-RNA yegciwane ibe yi-DNA ehambisanayo (i-cDNA) kusetshenziswa i-enzyme reverse transcriptase, kulandelwe ukukhuliswa kwe-cDNA kusetshenziswa i-PCR. I-RT-PCR ingabona wonke ama-serotype amane egciwane le-dengue ngokunemba okuphezulu futhi inikeze ulwazi mayelana nomthwalo wegciwane emzimbeni wesiguli. Naphezu kokuzwela kwayo okuphezulu nokucacile, imikhawulo yayo eyinhloko isidingo semishini ebizayo kanye nabasebenzi abanamakhono, okungenzeka ukuthi abatholakali kuzo zonke izikhungo zokunakekelwa kwempilo.
6. Izindlela Zokukhulisa Isothermal
Izindlela zokukhulisa i-isothermal ezifana ne-Loop-mediated Isothermal Amplification (LAMP) ziyindlela ehlukile ye-PCR engenziwa ngaphandle kwesidingo semishini yelabhorethri eyinkimbinkimbi. I-LAMP iyindlela yokukhulisa i-DNA esebenza ngokushisa okungaguquki, okwenza kube lula futhi kusheshe kune-PCR. I-LAMP iye yabonakala iphumelela ekutholeni igciwane le-dengue futhi ingasetshenziswa ezindaweni ezilinganiselwe izinsiza.
7. Indlela Yokunakekela (i-PoC)
Amadivayisi okuxilonga endaweni yokunakekelwa amadivayisi aklanyelwe ukusetshenziswa ngqo endaweni yokunakekelwa kwesiguli , enikeza imiphumela esheshayo ngaphandle kwesidingo selabhorethri yemitholampilo. Izibonelo zamadivayisi e-PoC zifaka phakathi ukuhlolwa okuhlukahlukene okusheshayo kokuxilonga (ama-RDT) kanye nama-kit e-antigen e-NS1. Amadivayisi e-PoC anamandla okuthuthukisa isivinini sokuxilonga kanye nokuphathwa kwesiguli, ikakhulukazi ezindaweni ezikude noma ngesikhathi sokuqubuka kwesifo.
Izinselele Zokuxilonga Umkhuhlane We-Dengue
Nakuba kunezindlela ezahlukene zokuxilonga ezitholakalayo, kusenezinselele ekuqinisekiseni ukutholakala komkhuhlane we-dengue okusheshayo, okunembile, futhi okungabizi kakhulu. Ezinye zalezi zinselele zifaka:
– Ukuguquguquka Kwezokwelapha: Izimpawu zomkhuhlane we-dengue zivame ukufana nezezinye izifo, ikakhulukazi ezigabeni zokuqala. Lokhu kwenza ukuxilongwa kwezokwelapha kube nzima ngaphandle kokusekelwa kwelabhorethri.
– Imikhawulo Yelabhorethri: Ezindaweni eziningi ezivame ukuba khona, izindawo zelabhorethri ezidingekayo zokuhlola okuthuthukile njenge-RT-PCR azitholakali ngaso sonke isikhathi. Ukuthembela ezindleleni ezisheshayo nezishibhile kuba yinto ebalulekile.
– Ukuzwela Nokucacisa: Ukuhlolwa kwe-Serological kanye nama-PoC kits kungenzeka kungabi nokuzwela okwanele kanye nokucacisa, ikakhulukazi ezigabeni zokuqala zokutheleleka noma ezifweni zesibili ezinezinhlobo ezahlukene zamagciwane.
– Izindleko: Ezinye izindlela zokuxilonga, ikakhulukazi lezo zama-molecule njenge-RT-PCR, zidinga izinsiza ezibalulekile ngokwemishini nezindleko, okungenzeka zingenzeki kuzo zonke izindawo.
Iziqondiso Zesikhathi Esizayo Ekuxilongweni Kwe-Dengue
Impumelelo ekulweni nomkhuhlane we-dengue ayixhomekile nje ekutholakaleni kusenesikhathi kanye nokuphathwa kweziguli, kodwa futhi nasekuvimbeleni nasekulawuleni ukudluliswa kwegciwane. Ngakho-ke, ukuthuthukisa izindlela zokuxilonga ezisheshayo, ezinembe kakhulu, ezishibhile, nezitholakala kalula kuyinto eza kuqala ocwaningweni kule ndawo.
Izindlela zesikhathi esizayo zingafaka phakathi ukuthuthukiswa kwama-biosensor asekelwe ku-nanotechnology, amapulatifomu okuxilonga ahlanganisa izivivinyo eziningi kudivayisi eyodwa, kanye nobuchwepheshe bokuxilonga obusezingeni eliphezulu obusekelwe ku-genomics ukuze kuhlinzekwe ulwazi oluphelele mayelana negciwane kanye nempendulo yesiguli.
Isiphetho
Umkhuhlane we-dengue hemorrhagic yisifo esidinga ukwelashwa okusheshayo nokufanelekile. Izindlela ezahlukene zokuxilonga ziye zasungulwa ukuze kutholakale ukutheleleka ngegciwane le-dengue, ngayinye inezinzuzo nezinkinga zayo. Ukuhlolwa kwe-serological, ukutholwa kwe-NS1 antigen, kanye nezindlela zama-molecule njenge-RT-PCR ezinye zezindlela eziyinhloko zokuxilonga i-dengue. Izinselele zokuxilonga zisekhona, kodwa ukusungula izinto ezintsha kwezobuchwepheshe kuyaqhubeka nokuthuthukisa ukunemba, isivinini, kanye nokutholakala kokuxilongwa. Imizamo yokubambisana phakathi kososayensi, abahlinzeki bezempilo, kanye nabenzi bezinqubomgomo iyisihluthulelo sokuxilonga nokulawula i-dengue okuphumelelayo.
