Chronic Hives
Chronic Hives, also known as Chronic Idiopathic Urticaria, is a condition where raised, itchy bumps appear on the skin. The cause for chronic urticaria is often hard to determine, although it may be caused by an autoimmune response. The symptoms can last for years, but hives typically disappear within 24 hours. Chronic Urticaria occurs in approximately 1% of the population and is more common in women than in men. Additionally, chronic urticaria can be incredibly debilitating as it can cause sleep deprivation and depression. Currently, there is no cure for chronic urticaria, although a combination of medication and lifestyle changes may help to alleviate symptoms. If you suspect you have chronic urticaria, seek a doctor`s diagnosis and treatment.
Symptoms of Chronic Hives
What are the common symptoms of chronic hives?
Common symptoms of chronic hives include the appearance of welts on the skin that are itchy, red, or white in color, and can range in size from small to large. These welts may change shape and move around the body, and are often accompanied by swelling in the affected area.
How long do the symptoms of chronic hives usually last?
The symptoms of chronic hives can last for several months or even years, and may come and go in cycles. Some people may experience symptoms for only a few weeks, while others may have them on and off for a decade or more.
What are the possible causes of chronic idiopathic urticaria?
The possible causes of chronic idiopathic urticaria, which is the medical term for chronic hives with an unknown cause, are not fully understood. However, it is thought to be related to an immune system dysfunction, with the body mistakenly attacking its own tissues and releasing histamine, which causes the hives.
Is stress a common trigger for chronic hives?
Stress can be a trigger for chronic hives in some people, although it is not a common cause. When the body is under stress, it produces higher levels of cortisol, a hormone that can contribute to inflammation and trigger histamine release.
Can certain medications cause chronic hives to occur?
Certain medications, such as antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), and blood pressure medications, can cause chronic hives to occur. These reactions are known as drug-induced urticaria and can occur within minutes or hours of taking the medication. However, in some cases, it may take weeks or months for the hives to appear after starting a medication.
Diagnosis of Chronic Hives
What tests are typically done to diagnose chronic hives?
Chronic hives are diagnosed through a series of tests conducted by a qualified healthcare professional. Some of the tests that may be done to diagnose chronic hives include a complete medical history review, physical examination, symptom analysis, and laboratory tests. Blood tests may be conducted to check for underlying medical issues such as thyroid or liver disease, as well as signs of infection or allergies. However, these tests are not always definitive in diagnosing chronic hives.
How does a doctor differentiate between chronic idiopathic urticaria and other skin conditions?
Chronic idiopathic urticaria (CIU) can be difficult to diagnose, as it often presents similarly to other skin conditions such as eczema or psoriasis. A doctor may differentiate between CIU and other skin conditions by considering the symptoms and duration of the hives, as well as conducting allergy tests and blood tests to rule out potential underlying causes. Additionally, a doctor may perform a physical examination and biopsy of the affected skin to confirm the diagnosis.
Are blood tests or skin tests typically ordered for diagnosis of chronic hives?
Both blood tests and skin tests may be ordered for the diagnosis of chronic hives. Blood tests may be conducted to detect underlying medical conditions such as thyroid disease, autoimmune disorders, or hepatitis. Skin tests, on the other hand, may be conducted to identify potential allergens that may be triggering a person`s hives.
Is a skin biopsy ever done to diagnose chronic hives?
Skin biopsy may be done if the diagnosis of chronic hives is uncertain, or to rule out other skin conditions. A skin biopsy involves the removal of a small sample of the affected skin and analysis under a microscope. This can help doctors to identify any specific characteristics or abnormalities that may be indicative of chronic hives.
What role do allergy tests play in diagnosing chronic idiopathic urticaria?
Allergy tests may play a role in diagnosing chronic idiopathic urticaria, as some people may develop hives as an allergic reaction to certain foods, medications, or environmental triggers. Allergy tests may include skin prick tests or blood tests to detect the presence of specific allergens. Additionally, an elimination diet may be recommended to help identify any potential food triggers that may be causing a person`s hives. However, it is important to note that not all cases of chronic hives are caused by allergies, and allergy tests may not always be definitive in identifying the cause of a person`s hives.
Treatments of Chronic Hives
What are the common first-line treatments for chronic idiopathic urticaria?
The common first-line treatments for chronic idiopathic urticaria include second-generation H1-antihistamines such as cetirizine and loratadine. These medications work by blocking the effects of histamine, which is released during an allergic reaction and causes the symptoms of urticaria. If first-line treatments are ineffective or poorly tolerated, it may be necessary to prescribe a higher dose of antihistamines or add in a second medication such as omalizumab, cyclosporine, or montelukast.
Can antihistamines effectively manage chronic hives?
Antihistamines can effectively manage chronic hives in many patients, although some patients may require higher doses or combination therapy with other medications. Second-generation H1-antihistamines are generally preferred over first-generation antihistamines due to their more favorable side effect profile. It is important to note that antihistamines do not cure chronic hives, but rather control the symptoms. Some patients may require long-term treatment with antihistamines to prevent relapse.
Are immunomodulators used in the treatment of chronic hives?
Immunomodulators such as omalizumab and cyclosporine are sometimes used in the treatment of chronic hives, particularly in patients who do not respond to antihistamines alone. Omalizumab is a monoclonal antibody that targets IgE, a key mediator of allergic reactions. Cyclosporine is an immunosuppressant that reduces inflammation by inhibiting T-lymphocyte activation. These medications have proven effective in treating chronic hives, but their use is typically reserved for refractory cases due to their potential side effects and cost.
Are there any dietary restrictions for managing chronic idiopathic urticaria?
There are no specific dietary restrictions for managing chronic idiopathic urticaria, although some patients may benefit from avoiding certain triggers such as alcohol, aspirin, or non-steroidal anti-inflammatory drugs (NSAIDs). It is also important for patients to maintain a healthy and balanced diet to support their overall health and immune function.
How long does it take for omalizumab to show efficacy in treating chronic hives?
Omalizumab has been shown to be effective in treating chronic hives, with a significant improvement in symptoms observed within the first 4 weeks of treatment. However, the response to omalizumab may vary between individuals, and some patients may require more than one dose to achieve optimal control of their symptoms.OMB-Control Number: 2900-0001.

Prognosis of Chronic Hives
What is the long-term prognosis for chronic hives?
The prognosis for chronic hives varies depending on the individual case. Chronic hives can last for months or even years, but some cases may resolve within a few months. Recurrence is common, and some people may experience flare-ups for many years. It is important to work with a healthcare provider to manage symptoms and identify any underlying conditions that may contribute to the development of chronic hives.

Can chronic hives become a chronic disease with serious consequences?
In rare cases, chronic hives may become a chronic disease with serious consequences. This may occur if the hives are associated with an underlying condition that is not properly managed. For example, chronic hives may be a symptom of an autoimmune disorder, and if left untreated, the underlying condition could cause serious health complications. However, most cases of chronic hives are not associated with serious health risks. Source: Mayo Clinic
Is the prognosis better for chronic hives with a known underlying cause?
The prognosis for chronic hives with a known underlying cause may be better than for cases where no underlying cause is identified. If the underlying cause is identified and properly treated, the hives may resolve or become easier to manage. However, in some cases, treating the underlying condition may not eliminate the hives completely. Source: AAD
How likely is it for chronic hives to spontaneously resolve?
It is possible for chronic hives to spontaneously resolve, but the likelihood of this happening varies depending on the individual case. Some people may experience spontaneous resolution after several months, while others may experience ongoing symptoms for many years. It is important to work with a healthcare provider to manage symptoms and identify any underlying conditions that may contribute to the development of chronic hives.

Are there any risk factors that could worsen the prognosis of chronic hives?
There are several risk factors that could worsen the prognosis of chronic hives. These include having a family history of hives or other allergic conditions, being female, experiencing stress, and having an autoimmune or thyroid disorder. In some cases, certain medications or foods may worsen symptoms. It is important to work with a healthcare provider to identify and manage any potential risk factors. Source: ACAAI
Prevention of Chronic Hives
What dietary changes can be made to prevent chronic hives?
Dietary changes that may prevent chronic hives include avoiding foods that trigger an allergic reaction. Some common culprits include milk, eggs, peanuts, tree nuts, fish, and shellfish. It is also recommended to avoid highly processed foods, sugary drinks, and alcohol, as these can weaken the immune system and exacerbate hives. Additionally, incorporating anti-inflammatory foods such as fruits, vegetables, whole grains, and lean proteins may be beneficial in reducing inflammation associated with chronic hives.

Is it recommended to avoid certain triggers to prevent chronic hives?
Avoiding certain triggers such as stress, extreme temperatures, and irritating fabrics can aid in the prevention of chronic hives. It is important to identify individual triggers as they vary from person to person. A healthcare provider may suggest keeping a journal to track potential triggers and help develop a plan to avoid them. It is also recommended to avoid nonsteroidal anti-inflammatory drugs (NSAIDs), as these may worsen hives in some individuals. (Source: American Academy of Dermatology Association)
How can stress management techniques aid in the prevention of chronic hives?
Stress management techniques such as relaxation exercises, mindfulness meditation, and yoga may aid in the prevention of chronic hives. Chronic stress can weaken the immune system and increase inflammation, which can exacerbate hives. Incorporating stress-reducing techniques into a daily routine may help reduce the frequency and severity of hives. (Source: Mayo Clinic)
Can exercise and physical activity help prevent chronic hives?
Exercise and physical activity may aid in the prevention of chronic hives by reducing stress levels and boosting the immune system. However, it is important to avoid activities that may trigger hives such as intense exercise or exposure to extreme temperatures. Consulting with a healthcare provider before starting an exercise routine is recommended, especially if hives are severe or occur frequently. (Source: American Academy of Dermatology Association)
Is avoiding known allergens the most effective method of preventing chronic hives?
Avoiding known allergens is an important method of preventing chronic hives. Individuals should work with a healthcare provider to identify potential trigger foods, medications, or environmental factors. It is also recommended to carry an epinephrine auto-injector in case of a severe allergic reaction. However, sometimes triggers may be unknown or difficult to avoid, and in these cases, medications and other treatments may be necessary to manage chronic hives.
