cold urticaria/anaphylaxis

The best way to prevent cold urticaria and a possible allergic reaction to cold is to avoid exposure to cold temperatures. Five of these patients (45.5%) had respiratory distress, and 8 (72.7%) had a decrease in their level of consciousness (dizziness, faintness, or hypotension). The medical term for hives that form on the skin when it’s exposed to the cold is cold urticaria (CU). A severe acute allergic reaction, called anaphylaxis, is possible if you have CU. There were 29.4% localized hives in patients with a positive cold-stimulation test (5 of 17 patients) versus 16.7% in patients with a negative cold-stimulation test (2 of 12 patients) and 35.3% systemic reactions in patients with a positive cold-stimulation test (6 of 17 patients) versus 41.7% in patients with a negative cold-stimulation test (5 of 12 patients); this trend was not significant (P = .64, Armitage’s trend test). Patients with negative cold-stimulation test (ice-cube challenge) at 10 minutes had similar symptoms and response to antihistamines as those patients with positive ice-cube-challenge test.

The test was interpreted as positive when a wheal appeared over the ice-cube application site. In these cases, the Central Nervous System and Cardiovascular System may be the first and only recognizable systems to fail. Six patients had the ice cube applied for only 5 minutes rather than the entire 10 minutes and tested negative. Most common method to confirm the diagnosis of CU is through ice cube challenge test, but 20% of patients with CU have negative ice cube challenge test results. These patients did not differ in any epidemiologic aspect, clinical presentation, or laboratory findings. This will allow your doctor to diagnose your symptoms. Pretreatment with an antihistamine is recommended, although its effect in preventing systemic reactions is unclear. cold air or water per se. Overall, little data are available on children. Cold urticaria can be diagnosed by placing an ice cube on the skin for five minutes. There is a higher rate of atopy and family history of atopy in those patients.

Response is also variable among patients.

Symptoms may disappear in 1 to 2 hours. Special attention should be paid to systemic reactions (anaphylaxis) and their prevention. These reactions could not be predicted based on available variables. The frequencies of cold-stimulation test (+/−) versus responses are shown in Table 3 (the patient who did not have the cold-stimulation test done had a poor response). Eleven patients (36.7%) experienced systemic symptoms (type 3). Interestingly, 1 patient has an identical twin who did not have cold urticaria but had allergic rhinitis. Healthline Media does not provide medical advice, diagnosis, or treatment. Drink beverages that are room temperature and don’t contain ice. The median duration of cold urticaria was 3.2 years (range: 0.5–13.5 years); the mean duration was 4.1 years. Cold urticaria occurs in children and may be associated with anaphylaxis. The repetition of the test was done at a different site because of local temporary tolerance to cold. Get the latest public health information from CDC: https://www.coronavirus.gov. A 2019 study found that taking 150 to 300 mg of omalizumab (Xolair) every 4 weeks was effective in treating CU that did not respond to antihistamines. We do not capture any email address.
