What does mean Acute Urticaria and what is the treatment of it?


Acute urticaria, also known as hives, is a common skin condition characterized by the sudden appearance of itchy, raised, and red welts on the skin. These welts, called wheals, can vary in size and shape and may appear and disappear within a few hours or days. Acute urticaria is considered acute when it lasts for less than six weeks. It can affect people of all ages, and it often occurs as a result of an allergic reaction or an immune response triggered by various factors.

The underlying cause of acute urticaria can vary and may include:

• Allergic reactions: These can be triggered by allergens such as certain foods (e.g., nuts, shellfish, eggs), medications (e.g., antibiotics, NSAIDs), insect bites or stings, and certain environmental factors (e.g., pollen, animal dander).

• Infections: Viral or bacterial infections, including common colds, sinusitis, strep throat, or urinary tract infections, can lead to acute urticaria.

• Autoimmune reactions: Sometimes, the body's immune system may mistakenly target its own tissues, causing urticaria.

• Physical factors: Exposure to certain physical stimuli like pressure, cold, heat, sunlight, exercise, or water can trigger hives in some individuals.

The treatment of acute urticaria aims to relieve symptoms, identify and manage the underlying cause, and prevent recurrence. Here are some common approaches:

• Avoid triggers: If the cause of urticaria is known, the first step is to avoid the trigger whenever possible. For example, if a specific food is identified as the cause, eliminating it from the diet is crucial.

• Antihistamines: These are the mainstay of treatment for acute urticaria. Antihistamines work by blocking the release of histamine, a chemical involved in the allergic response. They help relieve itching and reduce the appearance of hives. Non-drowsy antihistamines, such as cetirizine, loratadine, or fexofenadine, are usually preferred.

• Corticosteroids: In severe cases or when antihistamines alone are not sufficient, oral corticosteroids may be prescribed for a short period. These help to rapidly reduce inflammation and relieve symptoms. However, long-term use of corticosteroids is generally avoided due to potential side effects.

• Topical treatments: For localized hives, topical corticosteroid creams or ointments can be applied to reduce inflammation and itching.

• Identifying underlying causes: If the triggers are not obvious, further investigation may be necessary. This may involve blood tests, allergy testing, or other diagnostic procedures to identify potential allergens or underlying health conditions.

• Supportive measures: Taking cool showers or applying cold compresses to the affected areas can provide temporary relief. Wearing loose-fitting clothing and avoiding excessive heat or tight clothing can also help.

• Monitoring and follow-up: Acute urticaria often resolves on its own within a few weeks. However, if symptoms persist or recur, it is important to consult a healthcare professional for further evaluation and management.

In summary, acute urticaria is a temporary skin condition characterized by itchy welts or hives that can appear suddenly and resolve within six weeks. Treatment involves identifying and avoiding triggers, using antihistamines to alleviate symptoms, and considering corticosteroids for severe cases. If symptoms persist or recur, seeking medical advice is recommended to identify underlying causes and ensure appropriate management.
