ReferencesPrurigo nodularis es una afección cutánea crónica caracterizada por múltiples protuberancias y nódulos firmes, que generalmente se localizan en la parte externa de los brazos y las piernas. Estas lesiones pueden variar en color, desde tono carne hasta rosado, y causan picor intenso. Puede afectar a personas de cualquier edad y, a menudo, está asociada a otras enfermedades cutáneas que provocan picazón crónica, como la dermatitis atópica. Las opciones de tratamiento incluyen fármacos potentes anti‑picazón, inmunomoduladores y agentes dirigidos al sistema nervioso. El manejo del prurigo nodularis suele requerir una terapia a largo plazo.
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.

El tratamiento suele consistir en el uso de cremas o inyecciones de esteroides en la zona afectada. En casos más graves o refractarios, pueden ser necesarios tratamientos como la fototerapia o fármacos que inhiben el sistema inmunológico. La talidomida y la lenalidomida son opciones para casos graves, aunque pueden producir efectos secundarios importantes. Los tratamientos más nuevos (opioid receptor antagonists, neurokinin-1 receptor antagonists) son prometedores en el manejo del prurigo nodularis, ya que presentan menos efectos adversos en comparación con la talidomida o la lenalidomida.
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 es una afección de la piel caracterizada por picazón prolongada (que dura más de 6 semanas), lesiones cutáneas resultantes del rascado y antecedentes de rascado frecuente. Se asocia con neuroinflamación y fibrosis cutánea.
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 es una enfermedad cutánea crónica caracterizada por nódulos que pican. No sabemos exactamente qué la causa, pero parece que los problemas inmunológicos y nerviosos desempeñan un papel en el ciclo de picazón y rascado. En la actualidad, no existe ningún tratamiento aprobado por la FDA de EE. UU. específicamente para el 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.

○ Tratamiento: medicamentos de venta libre
Lavar la zona de la lesión con jabón no ayuda y puede empeorarla. Los ungüentos con esteroides de venta libre pueden aliviar los síntomas, pero generalmente es necesario aplicarlos durante varias semanas para observar mejoría. Continuar tomando antihistamínicos también ayuda a reducir la picazón.
