Hypersensitivity Angiitis: An Overview

Hypersensitivity angiitis, also known as hypersensitivity vasculitis or allergic angiitis, is a rare condition characterized by inflammation of blood vessels. It primarily affects the small and medium-sized blood vessels, including those in the skin, joints, and internal organs.

Although the exact cause of hypersensitivity angiitis is unknown, it is believed to be an autoimmune response triggered by an allergic reaction or an underlying infection. Certain medications, environmental factors, and chronic diseases may also contribute to its development.

Common symptoms of hypersensitivity angiitis include skin rash, joint pain, fever, fatigue, and gastrointestinal issues. These symptoms can vary in severity and may come and go over time. If left untreated, the condition may progress and lead to complications such as organ damage.

1. Skin manifestations: Skin rash is one of the most prominent features of hypersensitivity angiitis. It typically presents as small, raised red bumps or bruises, often affecting the legs and feet. These skin lesions may be painful or itchy.
2. Joint involvement: Joint pain and swelling are common in hypersensitivity angiitis. The joints most commonly affected are the knees, ankles, and wrists. In some cases, joint inflammation may be severe and restrict movement.
3. Systemic symptoms: Fever, fatigue, and weight loss are systemic symptoms that can accompany hypersensitivity angiitis. These symptoms may indicate widespread inflammation and immune system activation.
4. Organ involvement: In severe cases, hypersensitivity angiitis can affect internal organs such as the kidneys, lungs, heart, and gastrointestinal tract. Organ involvement may lead to more serious complications and requires immediate medical attention.

Diagnosis of hypersensitivity angiitis involves a combination of clinical evaluation, blood tests, and imaging studies. A skin biopsy may also be performed to examine the affected blood vessels under a microscope.

While there is no specific cure for hypersensitivity angiitis, treatment aims to control symptoms and prevent further complications. It typically involves the use of immunosuppressive medications to reduce inflammation and suppress the immune response. Additionally, identifying and addressing any underlying triggers or infections is essential.

In conclusion, hypersensitivity angiitis is a rare inflammatory condition that affects blood vessels throughout the body. Prompt diagnosis and appropriate management are crucial to prevent complications and improve the patient's quality of life. If you experience any of the symptoms associated with hypersensitivity angiitis, it is important to seek medical attention for proper evaluation and treatment.
