I-urticaria ye-Pigmental yisifo esivela ngenxa yokuqoqwa kwama-mast cells ezingxenyeni ezihlukene zomzimba, kufaka phakathi isikhumba. Ukubonakaliswa kwemitholampilo kubangelwa ukwakheka kwezakhi ezisebenzayo ngesikhathi se-degranulation. Lesi sifo kubhekwa njengingavamile. Kuhambisana nokubonakala kwamabala asundu emzimbeni. Igeleza ngamafomu amathathu, ahlukile ngobukhulu.
Izimbangela ze-urticaria enemibala

Iningi labacwaningi bakholelwa ukuthi ngokuyinhloko ukuzalwa kudla indima ebalulekile ekuthuthukiseni i-urticaria ye-pigmentary (mastocytosis) kubantu abadala. Ngokuvamile lesi sifo senziwa kubantu abahlobene nabo.
Abanye ososayensi bathi lesi sifo siwukuqhubeka kwe-pathologies ezithathelwanayo. Noma kuvela ngenxa yokungena emzimbeni wezinto ezimbi .
Ngesikhathi esifanayo, kwakungeke kwenzeke ukuthola izizathu eziqondile. Kuvela ngenxa yokuqoqwa kwama-mast cells e-tissue ehlukene, okubangela ukwandisa ukuqina kwe-vascular, ukwandiswa kwama-capillari kanye nokwanda kwe-edema, okuholela ekuboniseni isikhumba se-pathologies ebonakalayo.
Ukwelashwa kwe-urticaria yegazi

- I-Diazoline;
- I-Tavegil;
- Suprastin .
Uma kunesidingo, imithi ye-antiserotonin kanye ne-glucocorticoid iyasetshenziswa ngaphezu kwalokho.
Lapho kuhlanganiswa ama-node, ama-histaglobulin injection ayenziwa. Ngenxa yalokho, lo muntu kwezinye izindawo uhlala cishe u-pigmentation engapheli. Kuyinto efiselekayo ukugwema umonakalo owenziwe ngomshini nokushisa ku-epidermis.
Ngumuphi udokotela ophatha i-urticaria ye-pigmentary?
Ngokushesha ngemva kokubonakala kwezimpawu zokuqala, udinga ukuxhumana nodokotela we-dermatologist. Nguye ozocacisa uhlobo lwesifo, izinga lezinkinga futhi, uma kunesidingo, ukhethe ukuvakashelwa kochwepheshe abengeziwe.
