Final answer:

Neuropathic pruritus is often caused by histamine release, which interacts with nerve endings to cause itching. This is seen in conditions like eczema, where itching is a prominent symptom, and treatments usually focus on reducing inflammation and managing dryness of the skin.

Step-by-step explanation:

Neuropathic pruritus is a type of itching that occurs when nerves are stimulated. Factors such as histamine release, nerve compression, and environmental allergens can stimulate nerves to cause itching. Conditions like eczema are examples of allergic reactions that involve itching, where factors like dry skin can exacerbate the condition. The chemical mediators released during allergic reactions, such as histamine, interact with nerve endings to cause itching. Eczema is often treated with moisturizers and corticosteroid creams to manage symptoms like dry, itchy skin.

The correct answer to what stimulates nerves to cause itching in the context of neuropathic pruritus would be A) histamine release. Histamine's interaction with nerve endings is a primary cause of itching sensations.
