Te exact cause of NLD restillar, but several mechanisms have been proposed. Microangiopathy, a hallmark of diabetic complications, plays a central role. Tickening of thee basement mease andd endophelial damage in small blood vessels lead to reduced perfusion and tissue hypoxia.

Travement andManagement

Management of NLD is consigning because spontaneous resolution is uncontribun, and many treatments have limited revidence. The primary goals are te to prevent ulceration, control associated diabetes, and improwize cosmetic appearance.

Glicemic Control

Optymalizacja blood glucose levels is the most important intervention. Tight glycemic control may slow progression and reduce the risk of new lesions, although existing plaques rarely regress. Insulin pump therapy or continuous glucose monitoring can hill accesse target HbA1c below 7% (for most dilts). Referral to an endocrinologist is recomposed for diac etients with ND.

Terapia Topical i Intralesional

Wysoka potencja topical kortykosteroidy (np. klobetasol propionate) may reduce facimation and border activity, but they do not reverse atrophy and can cause skin thinning wich prolonged use. Intralesional corristesteroid injections (triamcinolone acetonide) are often used for active grands, with caution to avoid atrophy. Topical calcineurin morios (tacrolimus, pimecrolimus) are ain option for nonulated plaques, and some serie report benefit. Topical.

Leczenie systemowe

For extensive or progressive disease, systemic therapie may be considered. Low- dosie oral corresteroids (np., prednisone 15- 30 mg / day) can supres employon but are nott supporable for long- term use due to side effects andd risk of righer ing diabetetes. Hydroxychloroquine (200- 400 mg / day) has shown modett benefit in some patients, superible via immunomopulation.

Trainint of Ulcers

Ulcerated NLD wymaga agressive wound care. Standard management includes debridement, moist dressings, and infection control. Topical growth factors (np., platelet- derived growth factor) or bioconteleks skin substitutes (Apligraf) may by used for reframetory cases. Negative presure wound therapy can expegate granulation. Compression therapy is avoided unless venous innemency is also present, ay may reduce perfusion ND.
