The National Center for the Advancement of Translational Sciences defines cold urticaria as a condition that directly affects the skin. They add that the easiest way to diagnose this condition is based on the presence of certain signs and symptoms. Below you will find the signs and symptoms of cold urticaria, as well as the causes and possible treatments for it.
Causes: According to Demetrios Theodoropoulos, MD, DSc, MSc, FACMG, FAAP, with Allergy Associates of La Crosse, the cause of cold urticaria can not be identified. But the [OrganizaciónNacionaldeDesordenesRaras explains that this condition is the most common form of urticaria (urticaria). The National Center for the Advancement of Translational Sciences states that cold urticaria is not a hereditary condition, but in rare cases it has been associated with infectious diseases or blood conditions including cryoglobulinemia, chronic lymphocytic leukemia, lymphosarcoma , chicken pox, hepatitis virus and mononucleosis. However, cold family urticaria (another form of this condition) can be traced back to the long arm of chromosome one (1q40). Chromosomes are found in the nucleus of all the cells in the body that carry the genetic characteristics of each individual. The pairs of human chromosomes are numbered from 1 to 22, with a different pair 23 of X and Y chromosomes for men and two X chromosomes for women.
Signs and symptoms: National Organization of Rare Disorders states that in cold-acquired urticaria, the skin has an abnormal reaction to cold. For example: after exposing your skin to cold weather or swimming in cold water, your skin will usually turn red and itchy and itchy. These symptoms can also be accompanied by fever, anxiety, fatigue and even fainting at times. The National Center for the Advancement of Translational Sciences adds that the eruption will develop in 2-5 minutes and may last between 1 and 2 hours.
The symptoms of cold family urticaria take time to develop. Generally, it will take between 24-48 hours for the symptoms of cold family urticarial to appear. In addition, these symptoms can last up to 24 hours, but in more severe cases they can last up to 48 hours.
According to the National Organization of Rare Disorders there are subcategories of cold acquired urticaria; The first is primary urticaria due to cold. This may occur between 5 and 30 minutes after exposure to cold. Usually, itching and redness will occur first, which will then be followed by a burning sensation. Hives will appear that will last about 30 minutes. The exposed person may also experience headaches, wheezing or palpitations. The second subcategory is cold reflex urticaria. This is a generalized appearance of hives that occur when body temperature drops after exposure to cold applications.
Treatments: There are many ways to treat cold urticaria. If you want to use over-the-counter medications, the Mayo Clinic recommends antihistamines such as Claritin and Zyrtec. These medications will block the release of histamine that produces symptoms and may treat the mild symptoms of cold hives.
The National Center for the Advancement of Translational Sciences provides viable treatment options for cold urticaria. The first treatment is systemic corticosteroids, which are synthetic derivatives of the natural steroid, cortisol, which have anti-inflammatory effects. They also recommend Dapsone, which is used to treat certain types of skin disorders. It works by decreasing swelling and stops the growth of bacteria on the skin.
