I-Fungus Yezinzipho (Onychomycosis): Ukutheleleka Okungapheliyo Okubeka Ubulungisa Bakho Emsakazweni

I-Onychomycosis — igama lezokwelapha lokutheleleka kwezinzipho nge-fungus — ibangelwa ama-fungi dermatophyte (ngokuvamile i-Trichophyton rubrum kanye ne-Trichophyton mentagrophytes), ama-yeast (ikakhulukazi izinhlobo ze-Candida), kanye nama-mold angama-dermatophyte. Ama-dermatophytes abamba cishe u-90% wezokutheleleka kwezinzipho zomlenze futhi ingxenye encane yezokutheleleka kwezinzipho zeminwe. Lesi simo sithinta cishe u-14% wabantu abaningi eNyakatho Melika naseYurophu, futhi ukuvela kwaso kukhula kakhulu ngokuhamba kweminyaka — cishe u-50% wabantu abadala abangaphezu kweminyaka engu-70 banezinzipho ezithintekile.

Izinzipho zomlenze zithinteka kakhulu kunezinzipho zeminwe (cishe u-80% wezimo) ngoba izinyawo zihlala isikhathi eside ezindaweni ezishisayo, ezimanzi (izicathulo nezinsokhulu) ezikhuthaza ukukhula kwe-fungus, zine-circulation ye-bleed encishisiwe uma ziqhathaniswa nezandla (okwenza ukuvikelwa kwe-immunity kube nzima), futhi zikhona amathuba amaningi okuthi zibe ne-fungi ezindaweni ezithintekile. Izici ezithinta ubungozi zifaka ukuhamba kweminyaka (ukukhula kwezinzipho okuncane, ukujikeleza okuncishisiwe, iminyaka yokubhekana ne-fungus), i-diabetes (ukuphazamiseka kokuvikela kanye nokujikeleza), isifo se-peripheral vascular, ukuvikelwa kwe-immunity, i-athlete's foot (tinea pedis, evame ukuba yinsiza yokutheleleka kwezinzipho), ukulimala kwezinzipho, ukusebenza ezindaweni ezimanzi, kanye nokusebenzisa izindawo zokugezela noma amaphuli ajwayelekile. Ukutholakala kokuphazamiseka komzimba nakho kudlala indima — emindenini ethile, ukuvela kwe-fungus kuphakanyiswa kakhulu, kukhombisa ukwehluka okwenziwe ngokwemvelo ekuphenduleni kwe-immunity kuma-dermatophytes.

I-Onychomycosis ayigcini nje ngokukhathazeka kokubukeka: izinzipho ezithintekile zingaba zinde futhi zibe nzima ukuzisika, zibangele ubuhlungu uma ugqoke izicathulo, zidalule izindawo zokungena zokutheleleka kwe-bacteria (okuyingozi ikakhulukazi kubantu abane-diabetes), futhi zithinte kakhulu ikhwalithi yokuphila kanye nokuphila kahle kwengqondo. Kubantu abane-diabetes, i-onchomycosis ikhulisa ubungozi bezilonda ezinyaweni kanye nezokutheleleka eziphindaphindiwe ezingaholela ekusikeni.

I-Onychomycosis ibonakala ngezindlela eziningi ezihlukene, ngayinye ibonisa indlela ehlukile yokuhlasela kwe-fungus. I-distal lateral subungual onychomycosis (DLSO) iyinhlobo ejwayelekile kakhulu, ibamba cishe u-75% wezimo. I-fungus ihlasela ngaphansi komkhawulo omuhle wezinzipho (isiphetho osisika) kanye nezindonga zezinzipho eziseceleni, bese isakazeka iye kwi-cuticle.

Iziqinisekiso zifaka ukushintsha kombala okuphuma emlonyeni wezinzipho, okukhanya okuphuma emlonyeni wezinzipho, kanye nokwanda kancane kwezinzipho. I-proximal subungual onychomycosis (PSO) ayijwayelekile kubantu abanempilo kodwa iyindlela ejwayelekile kubantu abane-immunocompromised, ikakhulukazi labo abane-HIV. I-fungus ingena ngaphezulu komkhawulo wezinzipho (eduze kwe-cuticle) bese isakazeka iye emlonyeni wezinzipho — indlela ephikisanayo ne-DLSO.

Indawo emhlophe noma engacacile ibonakala eduze kwe-cuticle ezinziphoni ezibukeka zempilo, ikakhulukazi kumuntu omncane, kufanele ibangele ukukhathazeka kokuphazamiseka kwe-immunity. I-white superficial onychomycosis (WSO) ibonakala njengezindawo ezimhlophe, ezinjengokhuni, ezithambile ebusweni bezenzipho. Ngokungafani nezinye izinhlobo lapho i-fungus ihlasela ngaphakathi noma ngaphansi kwezinzipho, i-WSO ibandakanya ukuhlinzekwa kwe-fungus ebusweni be-outer nail plate.

Lokhu kwenza kube yindlela elula kakhulu yokwelapha — ama-antifungals we-topical angafinyelela ngqo ekutheleleni. I-total dystrophic onychomycosis (TDO) imele isimo sokugcina lapho zonke izinzipho ziqinile, ziqhekekile, futhi zibhujiswa ukutheleleka kwe-fungus. I-TDO ingavela njengokuthuthuka kwazo zonke lezi zindlela ezingenakwelashwa ezishiywe zingeziwe izinyanga noma iminyaka.

I-candidial onychomycosis ibangelwa ikakhulukazi izinhlobo ze-Candida futhi ithinta kakhulu izinzipho zeminwe, ikakhulukazi kubantu abane-chronic moisture exposure (abapheki, abapheki beziphuzo, abasebenzi bempahla). Ivame ukuhlanganisa izindonga zezinzipho eziphezulu neziseceleni ezihambisana nokukhukhuleka nokuthambekela (paronychia). Ukuqonda kahle indlela kusiza ukuhlela izinqumo zokwelashwa futhi kunganikeza izinkomba mayelana nesimo sokuphila esingaphansi.

Umthetho obalulekile ekuphathweni kwe-onchomycosis ukuqinisekisa ukuxilongwa ngaphambi kokuzibophezela ekwelashweni — ikakhulukazi ekwelashweni kwe-oral antifungal. Kuze kube ngu-50% wezimpaphe ezibukeka zingajwayelekile (ezibukeka kabi) azidalwanga ngempela ukutheleleka kwe-fungus. Izimo ezifanayo ne-onchomycosis zifaka i-nail psoriasis (enye yezinto ezivame kakhulu, ebangela ukungena, ukushintsha kombala, nokwanda), ukulimala kwezinzipho (ukulimala okuphindaphindiwe okuvela ezicathulweni ezicindezelayo noma ukuhamba), i-lichen planus ye-nail, i-melanonychia (ukushintsha kombala okumnyama kwezinzipho ngenxa ye-melanin), kanye nezinguquko zezinzipho ezivela kwi-dermatitis noma ekujikelezeni okuphansi.

Ukwelapha isimo se-nail esingekho ne-fungus ngezinyanga zokwelashwa kwe-antifungal akusebenzi, kubiza kakhulu, futhi kukhombisa iziphumo ezimbi ezivela emithini engadingekile. Izindlela zokuxilonga zifaka i-potassium hydroxide (KOH) preparation, lapho ama-scrapings ezinzipho ehlanjululwa ku-KOH solution bese ehlolwa ngaphansi kwe-microscope ukuze kutholakale izinto ze-fungus — imiphumela itholakala ngemizuzu, ubuningi bayo buphakathi kuka-70-80%. I-fungal culture ibandakanya ukuthumela ama-clippings ezinzipho noma ama-scrapings emlabathini ukuze kutholakale umkhiqizo othile — imiphumela ithatha izinsuku ezi-3-6 kodwa inikeza ukuhlonza kwezinhlobo okungasiza ekukhetheni ukwelashwa.

I-PAS (periodic acid-Schiff) staining ye-clippings zezinzipho ezihlolwe ngokuhlonza inobuningi obuphakeme (ngaphezulu kuka-90%) futhi ithatha izinsuku ezi-1-2. Ukuhlolwa kwe-molecular okuhloswe nge-PCR kusemisha, kusheshayo, futhi kunobuningi obuphakeme kodwa akutholakali kuzo zonke izindawo. Umphumela omubi we-KOH noma we-culture awuqinisekisi ukuthi i-onchomycosis ayikho (ama-false negatives avamile), ngakho ukuhlolwa kabusha noma izindlela ezihlukile zingase zidingeke uma ukukhathazeka kwe-clinical kuqhubeka kuphakama. Ngakolunye uhlangothi, umphumela omuhle emlabathini ohlanganiswe nokubukeka kwe-clinical okuhambisanayo unikeza ukuzethemba ukuze uqale uhambo lokwelashwa olude uqinisekile ukuthi ukuxilongwa kulungile.

Ukwelashwa kwe-onchomycosis kudinga ukubekezela kanye nezibopho eziphusile — noma ngabe izindlela ezisebenza kahle kakhulu, amazinga aphelele okwelashwa akukude kakhulu no-100%, futhi ukuthuthukiswa okubukekayo kuthatha isikhathi ngoba izinzipho eziphilile kumele zikhule ukuze zifake indawo yezinzipho ezilimazekile. Izinzipho zomlenze zikhula cishe u-1-2mm ngenyanga, okusho ukuthi ukufaka izinzipho zomlenze kuthatha izinyanga eziyi-12-18. Izinzipho zeminwe zikhula ngokushesha (3-4mm/ngenyanga) zifaka ngokuphelele ezinyangeni eziyi-6-9.

Imithi ye-oral antifungal iyindlela ephumelelayo kakhulu yokwelapha i-onchomycosis ephakathi nendawo kuya kwenhle. I-Terbinafine (Lamisil) iyisilinganiso esiyigugu sokutheleleka kwe-dermatophyte, ethathwa nsuku zonke izinsuku eziyi-6 (izinzipho zeminwe) noma izinsuku eziyi-12 (izinzipho zomlenze), inezinga lokwelashwa le-mycological elingu-70-80% kanye nezinga lokwelashwa eliphelele elingu-38-50%. Ivame ukubekezelelwa kahle kodwa idinga ukuqapha ukusebenza kwe-liver okujwayelekile, njengoba izimo ezithile ze-hepatotoxicity zenzeka.

Iziphumo ezivamile zifaka ukuphazamiseka kwe-gastrointestinal, ukungahambi kahle kokunambitha, kanye nekhanda. I-Itraconazole (Sporanox) iyindlela ehlukile, ivame ukusetshenziswa ekudleni kwe-pulse (isonto elilodwa, izinsuku ezintathu ziphume, kuphindwe izikhathi ezi-2-3), ephumelelayo kumafungus amaningi ahlukene kuhlanganise ne-Candida. Inezinye izixhumanisi zemithi eziningi kune-terbinafine futhi idinga ukuqapha i-liver.

I-Fluconazole kwesinye isikhathi isetshenziswa ngaphandle kwemithetho yokwelapha ezinsukwini ezivamile ezinde. Ukwelashwa kwe-topical kuncane kakhulu kunezidakamizwa ze-oral eziningi ze-onchomycosis ngoba i-nail plate isebenza njengomgoqo ovimbela ukungena kwemithi ebhedini ye-nail kanye ne-matrix lapho ukutheleleka kukhona. I-Ciclopirox nail lacquer (Penlac) yayingeyokuqala eyamukelwe yi-FDA, inezinga eliphansi lokwelashwa elingu-5-10%.

I-Efinaconazole (Jublia) kanye ne-tavaborole (Kerydin) izixazululo ezintsha ze-topical ezine-penetration ethuthukisiwe kanye nezinga lokwelashwa elingu-15-20%. Ukwelashwa kwe-topical kufanelekile kakhulu ezimweni ezilula, ezisencane, i-white superficial onychomycosis, kubantu abangakwazi ukuthatha ama-antifungals we-oral ngenxa yokuxhumana kwemithi noma ukukhathazeka kwe-liver, futhi njengokuhlanganiswa kokwelashwa kwe-oral ukuze kuthuthukiswe amazinga okwelashwa. Ukwelashwa kokuhlanganisa (oral plus topical) kufinyelela amazinga aphezulu okwelashwa kunezindlela ezilodwa.

Ukususwa kwe-mechanical — ukuhlinzekwa kwezinzipho ezinde, ezibukeka kabi, ngokuhlinzwa ngochwepheshe — kuthuthukisa kokubili ukungena kwemithi ye-topical kanye nokubukeka kokwakhiwa ngesikhathi sokwelashwa eside. Ukwelashwa kwe-laser kukhushulwa kakhulu kodwa ubufakazi bokusebenza buhlala buncane futhi buphikisana, lapho izifundo ezinhle kakhulu zikhombisa izinzuzo eziphansi noma akukho zinzuzo uma kuqhathaniswa ne-placebo.

Izinga lokuphindaphinda emva kokwelashwa kwe-onchomycosis empumelelweni liphansi — kulindeleke ukuthi kube ngu-10-50% eminyakeni embalwa — okwenza ukuvimbela kube isu elibalulekile lesikhathi eside. Izinyathelo ezibaluleke kakhulu zokuvimbela ziqondiswe ezimweni zemvelo ezisebenzisa ama-fungi. Gcina izinyawo zomile: shintsha izinsokhulu nsuku zonke (kaningi uma izinyawo zikhwehlela kakhulu), khetha izinsokhulu ezikhipha umswakama ezivela ku-synthetic noma ku-wool kune-cotton, shintsha izicathulo nsuku zonke ukuze zome ngokuphelele phakathi kokugqoka, futhi usebenzise i-powder ye-antifungal noma i-spray ezicathulweni.

Phatha i-athlete's foot ngokushesha nangokugcwele, njengoba i-tinea pedis iyinsiza ejwayelekile yokutheleleka kwezinzipho — i-fungus isakazeka kusuka esikhumbeni esithintekile phakathi kwezinyawo iye ebhedini ye-nail. Vikele izinyawo ezindaweni ezimanzi ezijwayelekile: gqoka ama-sandals noma izicathulo zamanzi ezindaweni zokugezela, ezikhungweni zokugcina, ezindaweni zamapuli, nasezindlini zokugezela zezitolo. Gcina ukuhygiene kwezinzipho okufanele: sika izinzipho ngqo (ungazijikijeli emaphethelweni, okudala izikhala zokungena kwe-fungus), gcina izinzipho zifushane, ungabelani ngama-clippers ezinzipho noma ama-files, futhi uhlanze amathuluzi phakathi kokusetshenziswa nge-alcohol yokuhlanza.

Gwema ukulimala kwezinzipho: gqoka izicathulo ezifanele ezinemikhawulo efanele, sika izinzipho njalo ukuze uvimbele ukuthi zibe neziphakamiso ezithintekayo, futhi uvikele izinzipho zomlenze ngesikhathi semidlalo nasezinhlelweni zomzimba. Bheka izici ezithinta ubungozi lapho kungenzeka: phucula ukulawulwa kwegazi lesikhumba kwi-diabetes, xoxa ngezinguquko zemithi yokuvikela ne-dokotela wakho, futhi uthuthukise ukujikeleza kwe-peripheral ngokuhamba njalo. Abanye odokotela bezokwelapha baphakamisa ukufaka i-topical antifungal ezinziphweni ezithintekile ngemuva kokuphothulwa kokwelashwa — ukufaka i-antifungal nail lacquer noma isixazululo masonto onke kungavimbela ukutheleleka kabusha.

Kubantu abane-onchomycosis ephindaphindiwe, izinyanga eziphindaphindiwe zemithi ye-oral antifungal zingase zidingeke. Ukugcina amathuluzi ezinzipho ehlanzekile, ukugwema amathuluzi okuphatha ahlanganyelwe ezindaweni zokugezela (thatha yakho noma uqinisekise ukuhlanzwa kahle), nokuphatha wonke amalungu omndeni anokutheleleka kwe-fungus ngesikhathi esifanayo kuvimba ukutheleleka kabusha ezindaweni ezabelwana ngazo.

Akukho zonke izinzipho ezishintshile noma ezinde ezihlobene ne-fungus, futhi ukuhlolwa kochwepheshe kubalulekile ngaphambi kokuthi uqale ukwelashwa. Bheka umhlinzeki wezempilo uma uqaphela ukushintsha kombala kwezinzipho (ukukhanya, ukushintsha kombala, noma izindawo ezimhlophe), ukwanda okwenza kube nzima ukusika, ukuhlekwa noma ukuvuvukala komkhawulo wezinzipho, ukuhlukana kwezinzipho ebhedini ye-nail, noma ubuhlungu ezinziphweni ezithintekile. Abantu abane-diabetes kufanele bafune ukuhlolwa ngokushesha nganoma yiziphi izinguquko zezinzipho, njengoba i-onchomycosis ikhulisa ubungozi bokutheleleka kwe-bacteria okuphindaphindiwe nezilonda ezinyaweni.

Uma usukhumbule i-fungus yezinzipho eyaphumelela, futhi uqaphele izimpawu zokuqala zokuphindaphinda, ukungenelela kwangaphambili kusebenza kangcono kunokulinda ukuthi ukutheleleka kube sekuqinisekisiwe. Umugqa omnyama noma ibhendi ezinziphweni (melanonychia) idinga ukuhlolwa ngokushesha ukuze kuqinisekiswe ukuthi akukhona i-melanoma subungual — lokhu kubalulekile ikakhulukazi uma umugqa omnyama ungowakamuva, ukhula kancane, noma uhambisana nokuphazamiseka kwezinzipho noma i-periungual pigmentation (i-Hutchinson sign). Ubuhlungu, ukuvuvukala, nokubomvu eduze komkhawulo wezinzipho (acute paronychia) kungase kubonise ukutheleleka kwe-bacteria okudinga ukwelashwa kwe-antibiotic kunokwelashwa kwe-antifungal. Uma ukwelashwa kwe-antifungal okuthengwayo kungaphumelelanga ngemva kwezinyanga ezi-3-6 zokusebenzisa njalo, ukuxilongwa kochwepheshe (ukuqinisekisa i-fungal etiology) kanye nokwelashwa kwe-prescription kunikeza amazinga aphezulu okwelashwa.

Izinguquko zezinzipho zivamile futhi zinezizathu eziningi ezingaba khona — ukuhlole ukuthi ingabe izinzipho ezishintshile noma ezinde zidalwe ukutheleleka kwe-fungus, i-psoriasis, ukulimala, noma enye isimo kuyisinyathelo sokuqala esibalulekile ngaphambi kokuzibophezela ezinyangeni zokwelashwa. I-Skinscanner inikeza ukuhlolwa kokuqala okulula ngokuhlaziya izithombe zezinzipho zakho ezithintekile ngezici ezihambisana ne-onchomycosis uma kuqhathaniswa nezinye izimo zezinzipho. Ngokuthwebula izithombe zezinzipho zakho ekuqaleni kokwelashwa nasezikhathini ezinyangeni, udala irekhodi elingokoqobo lokuphendula kokwelashwa elikhombisa ukuthuthuka kancane, okungase kungabonakali ekuhloleni kwansuku zonke.

Njengoba ukwelashwa kwezinzipho zomlenze kuthatha izinyanga eziyi-12-18 ukuze kukhombise imiphumela ephelele, ukuba ne-timeline yezithombe kunikeza umdlandla wokugcina ukwelashwa futhi kukhombisa ubufakazi obungokoqobo ukuze wabelane nomhlinzeki wezempilo wakho uma uhlola ukusebenza kokwelashwa. I-Skinscanner ingasiza futhi ukukuhlola izimpawu zokuphindaphinda ngemva kokwelashwa okuphumelelayo — izinguquko ezincane zokuqala zihlala zikhona kalula ezithombeni ezihambisanayo kunokuhlolwa okungajwayelekile. Nakuba ukuhlaziywa kwe-AI kungakwazi ukufaka esikhundleni sokuqinisekiswa kwemlabathi kwe-fungus, kunikeza isinyathelo esibalulekile sokuhlola esisiza ukukhetha ukuthi ngabe ukuhlolwa kochwepheshe kuyadingeka futhi kusekela ukulandelela ukusebenza kokwelashwa uma i-therapy iqala.
