Aquagenic Pruritus

Aquagenic pruritus is a skin condition that causes intense itching and discomfort when the skin comes into contact with water, regardless of its temperature. In this article, we will provide simplified explanations for various aspects of aquagenic pruritus, including its types, causes, symptoms, diagnostic tests, treatments, and drugs.

Types of Aquagenic Pruritus:

  1. Primary Aquagenic Pruritus: This is the most common type and occurs without an underlying medical condition.
  2. Secondary Aquagenic Pruritus: Linked to other health conditions, such as polycythemia vera or myeloproliferative disorders.

Causes of Aquagenic Pruritus:

  1. Skin Barrier Dysfunction: Water can disrupt the skin’s protective barrier, leading to itching.
  2. Histamine Release: Water can trigger the release of histamine, a chemical that causes itching.
  3. Genetic Predisposition: Some individuals may inherit a genetic predisposition to this condition.
  4. Polycythemia Vera: A rare blood disorder that can cause secondary aquagenic pruritus.
  5. Myeloproliferative Disorders: Conditions that affect blood cell production, often associated with secondary aquagenic pruritus.
  6. Hormonal Changes: Hormonal fluctuations can sometimes worsen symptoms.
  7. Stress and Anxiety: Emotional stress can exacerbate itching.
  8. Medications: Certain drugs may trigger or worsen aquagenic pruritus as a side effect.
  9. Underlying Allergies: Allergic reactions can contribute to skin irritation.
  10. Dehydration: Insufficient hydration may make the skin more sensitive to water.
  11. Nerve Sensitivity: Overactive nerves can play a role in the condition.
  12. Skin Disorders: Conditions like eczema or psoriasis can make the skin more susceptible to aquagenic pruritus.
  13. Excessive Sweating: Sweat mixed with water can cause irritation.
  14. Cold Weather: Low temperatures can exacerbate symptoms.
  15. Hot Showers: Hot water can be more irritating than cold water.
  16. Chemical Sensitivities: Some people may react to chemicals in tap water.
  17. Friction: Rubbing the skin with a towel or cloth can trigger itching.
  18. Exposure to Chlorine: Chlorinated water in pools can be a trigger.
  19. Excessive Scrubbing: Aggressive washing can damage the skin.
  20. Menopause: Hormonal changes during menopause can affect symptom severity.

Symptoms of Aquagenic Pruritus:

  1. Itching: Intense and often immediate itching upon contact with water.
  2. Burning Sensation: The skin may feel like it’s burning or stinging.

Diagnostic Tests for Aquagenic Pruritus:

  1. Water Test: A simple test where a small area of skin is exposed to water to observe the reaction.
  2. Histamine Test: Injection of histamine under the skin to see if it triggers itching.
  3. Skin Biopsy: A small sample of skin is taken for examination.
  4. Blood Tests: To check for underlying conditions.
  5. Skin Allergy Testing: To identify potential allergens.
  6. Medical History: Discussing symptoms and triggers with a healthcare provider.
  7. Thermography: Measures changes in skin temperature after water exposure.
  8. Patch Testing: Identifies contact allergies.
  9. Phototesting: Tests skin’s reaction to light and water.
  10. Imaging Tests: To rule out other underlying conditions.
  11. Neurological Assessment: To evaluate nerve function.
  12. Biophysical Testing: Measures skin’s response to water at different temperatures.
  13. Allergen-specific IgE Testing: Checks for specific allergens.
  14. Scratch Test: Skin is scratched to observe the reaction.
  15. Intradermal Test: Substances are injected into the skin to assess reactions.
