ReferencesPrurigo nodularis je dlhodobý stav kože charakterizovaný viacerými pevnými hrbolčekmi a uzlíkmi, ktoré sa najčastejšie vyskytujú na vonkajších častiach rúk a nôh. Tieto hrbole môžu mať rôznu farbu – od telovej po ružovú – a intenzívne svrbia. Môže postihnúť ľudí akéhokoľvek veku a často je spojené s inými kožnými ochoreniami spôsobujúcimi chronické svrbenie, napríklad s atopickou dermatitídou. Možnosti liečby zahŕňajú silné antipruriginózne lieky, imunosupresívne prípravky a lieky pôsobiace na nervový systém. Kontrola prurigo nodularis zvyčajne vyžaduje dlhodobú liečbu.
Prurigo nodularis is a chronic disorder of the skin that is classically seen as multiple, firm, flesh to pink colored papules, plaques and nodules commonly located on the extensor surfaces of the extremities. The lesions are very pruritic and can occur in any age group. It is commonly associated with another disease such as atopic dermatitis or any dermatoses associated with chronic pruritus. The therapeutic approach is wide-arrayed ranging from treatments that act as - potent antipruritics, immunomodulators, and neuromodulators. Treatment in an established case is prolonged and improving patient compliance with education and counseling is important.

Liečba zvyčajne zahŕňa použitie krémov alebo injekcií steroidov na postihnutú oblasť. V závažnejších alebo odolných prípadoch môžu byť potrebné liečby, ako je svetelná terapia alebo lieky, ktoré potláčajú imunitný systém. Thalidomid a lenalidomid sú možnosti pre ťažké prípady, avšak môžu mať vážne vedľajšie účinky. Novšie liečby (opioid receptor antagonists, neurokinin-1 receptor antagonists) sú sľubné pri liečbe prurigo nodularis a majú menej vedľajších účinkov v porovnaní s thalidomidom alebo lenalidomidom.
Treatment typically relies on the use of topical or intralesional steroids, though more severe or recalcitrant cases often necessitate the use of phototherapy or systemic immunosuppressives. Thalidomide and lenalidomide can both be used in severe cases; however, their toxicity profile makes them less favorable. Opioid receptor antagonists and neurokinin-1 receptor antagonists represent two novel families of therapeutic agents which may effectively treat PN with a lower toxicity profile than thalidomide or lenalidomide.

Chronic prurigo je kožné ochorenie charakterizované dlhotrvajúcim svrbením (trvá viac ako 6 týždňov), kožnými léziami súvisiacimi so škrabancami a častým škrabaním v anamnéze. Zahŕňa neurozápal a fibrózu v koži.
Chronic prurigo (CPG) is a neuroinflammatory, fibrotic dermatosis that is defined by the presence of chronic pruritus (itch lasting longer than 6 weeks), scratch-associated pruriginous skin lesions and history of repeated scratching.

Prurigo nodularis je dlhotrvajúci kožný problém charakterizovaný svrbivými uzlami. Presne nevieme, čo ho spôsobuje, ale zdá sa, že v cykle svrbenia a škrabania zohrávajú úlohu imunitné a nervové poruchy. V súčasnosti neexistuje žiadna liečba schválená americkým FDA špeciálne pre Prurigo nodularis.
Prurigo nodularis is a long-lasting skin problem marked by itchy nodules. We don't know exactly what causes it, but it seems that immune and nerve issues play a role in the itch-scratch cycle. Right now, there aren't any treatments approved by the US FDA specifically for prurigo nodularis.

○ Liečba – voľne predajné lieky
Umývanie postihnutej oblasti mydlom vôbec nepomáha a môže to zhoršiť stav. Voľne predajné steroidné masti môžu pomôcť zmierniť príznaky, ale zvyčajne je potrebné ich aplikovať niekoľko týždňov, aby došlo k zlepšeniu. Pokračovanie v užívaní antihistaminík tiež pomáha zmierniť svrbenie.
