What is Aquagenic Urticaria?
Aquagenic urticaria is a type of chronic urticaria(hives) because of water. Even tears, sweat and sometimes drinking water shows its effects. It affects only about 50 people in the world. A study believes that among the limited cases reported, The prevalence of this condition seems to be more females typically occurring during puberty or postpuberty. The study describes the condition as- 'Aquagenic urticaria (AU) is a rare inducible form of physical urticaria, which occurs in response to cutaneous exposure to water, including sweat and tears. Patients present with characteristic 1–3 mm folliculocentric wheals with surrounding 1–3 cm erythematous flares within 20–30 minutes following skin contact with water. In rare cases, there are concomitant systemic symptoms, such as wheezing or shortness of breath.'
1.Wheals (a red, swollen mark) and flares within 20–30 minutes following skin contact with water.
2. Patients can also experience associated symptoms, including pruritus, burning, and uncomfortable prickling.
3. Urticarial lesions (severe itching) usually resolving within 30–60 minutes of cessation of water contact with the skin.
4. Common appearance around the trunk and upper arms, usually sparing the palms and soles.
5. Rarely, patients can experience systemic symptoms such as wheezing or shortness of breath.
The condition cannot be cured but can be managed only up to a certain extent. Since the causative factor of AU is water is, simple avoidance of the offending substance presents as an impractical, at times impossible, a task for patients. The study says, 'The urticarial symptoms, such as wheal formation and pruritus, are thought to be mediated, at least partially, by the effects of histamine on the H1 receptor. Therefore, the first-line therapy for AU generally consists of oral H1 antihistamines. First-generation H1 antihistamines have significant sedative and anticholinergic side effects; these undesirable effects can continue much longer than the therapeutic, anti-pruritic effect, which only lasts ~4–6 hours.'
The rarity of this condition makes the diagnosis extremely difficult and the management as well. The study further says, 'While water may be a seemingly innocuous substance to most of us, there are patients who suffer from side effects of exposure to water. A clinical history of hives in response to water exposure, as well as a positive result of a water challenge test, are keys to diagnosing AU. It is critical to differentiate AU from other physical urticarias.'
