I-Psoriasis, isifo sesikhumba esingamahlalakhona, esiphindaphindayo, esivuvukalayo nesihambisana nesimiso somzimba esibangelwa yimiphumela yezakhi zofuzo kanye nemvelo.I-Psoriasis ngaphezu kwezimpawu zesikhumba, kuzoba khona nezimila zenhliziyo, ze-metabolic, zokugaya ukudla kanye nezimila ezinobungozi kanye nezinye izifo eziningi. Nakuba ingathelelani, ilimaza kakhulu isikhumba futhi inomthelela omkhulu ekubukekeni, okuletha umthwalo omkhulu ngokomzimba nangokwengqondo ezigulini futhi kuthinte kakhulu ikhwalithi yokuphila.
Ngakho-ke, i-ultraviolet phototherapy iphatha kanjani i-psoriasis?
1.Tukwelashwa okuvamile kwe-psoriasis
Imithi yokwelapha esetshenziswa endaweni yokwelapha iwukwelashwa okuyinhloko kwe-psoriasis emnene kuya kwephakathi. Ukwelashwa kwemithi yokwelapha esetshenziswa endaweni yokwelapha kuncike eminyakeni yesiguli, umlando, uhlobo lwe-psoriasis, indlela yesifo kanye nezilonda.
Imithi evame ukusetshenziswa yi-glucocorticoids, i-vitamin D3 derivatives, i-retinoic acid njalo njalo. Ukusetshenziswa kwemithi yomlomo noma i-biologics njenge-methotrexate, i-cyclosporine kanye ne-retinoic acid kunconywa ezigulini ezine-scalp psoriasis ehambisana nezilonda eziphakathi kuya kwezinzima.
2.Tizici ze-ultraviolet phototherapy
Ukwelashwa nge-ultraviolet phototherapy kuyindlela yokwelapha enconyelwa kakhulu ye-psoriasis ngaphezu kwemithi. Ukwelashwa nge-phototherapy ngokuyinhloko kubangela ukuvela kwamaseli e-T ezilondeni ze-psoriatic, ngaleyo ndlela kuvimbele isimiso somzimba sokuzivikela esisebenza ngokweqile futhi kukhuthaze ukubuyela emuva kwezilonda.
Ihlanganisa kakhulu i-BB-UVB(>280~320nm), i-NB-UVB(311±2nm), i-PUVA(yokugezela ngomlomo, yokwelapha kanye neyendawo) kanye nezinye izindlela zokwelapha. Umphumela wokwelapha we-NB-UVB wawungcono kune-BB-UVB futhi ubuthakathaka kune-PUVA ekwelapheni i-psoriasis nge-UV. Kodwa-ke, i-NB-UVB iyindlela yokwelapha ye-ultraviolet esetshenziswa kakhulu ephephile kakhulu futhi elula ukuyisebenzisa. Ukwelashwa kwe-UV okune-topical kunconywa lapho indawo yesikhumba ingaphansi kuka-5% wendawo yonke yomzimba. Lapho indawo yesikhumba ingaphezu kuka-5% yendawo yomzimba, kunconywa ukwelashwa kwe-UV okuhlelekile.
3.Ukwelashwa kwe-psoriasis nge-NB-UVB
Ekwelapheni i-psoriasis, ibhendi eyinhloko esebenzayo ye-UVB isebangeni elingu-308 ~ 312nm. Ibhendi ephumelelayo ye-NB-UVB (311±2nm) ekwelapheni i-psoriasis ihlanzekile kakhulu kuneye-BB-UVB (280 ~ 320nm), futhi umphumela ungcono, useduze nomphumela we-PUVA, futhi unciphisa ukusabela kwe-erythematous okubangelwa ibhendi engasebenzi. Ukuphepha okuhle, akukho ukuhlangana nomdlavuza wesikhumba okutholiwe. Njengamanje, i-NB-UVB iyindlela yokwelapha ethandwa kakhulu ekwelapheni i-psoriasis.
