Understanding IgA Vasculitis: Symptoms, Causes, and Latest Treatment Approaches in 2025
Immunoglobulin A vasculitis (IgA vasculitis), formerly known as Henoch-Schönlein purpura (HSP), is a form of small-vessel vasculitis that most commonly affects the skin, joints, gastrointestinal tract, and kidneys. Although it is more frequently diagnosed in children, adults can also develop the condition, often with more serious complications. As research advances, understanding of this disease and its management continues to evolve.

What Is IgA Vasculitis?
IgA vasculitis is an autoimmune disorder where the immune system mistakenly attacks the blood vessels, causing inflammation and bleeding under the skin. The exact trigger is not fully understood, but the hallmark of the disease is the deposition of immunoglobulin A (IgA) in the small blood vessels. This immune complex deposition leads to inflammation, particularly in the skin and organs like the kidneys and intestines.
Common Symptoms to Recognize
Symptoms typically begin suddenly and can vary in intensity. The most recognizable sign is a purplish rash, usually appearing on the lower legs and buttocks. This rash, known as palpable purpura, does not fade when pressed and may be accompanied by other symptoms, such as:
Joint pain and swelling: Especially in the knees and ankles
Abdominal pain: Often cramping, sometimes accompanied by nausea or vomiting
Blood in the urine or kidney involvement: Indicating possible nephritis
Fever or general malaise: In more severe or systemic cases
In children, symptoms may resolve on their own, but adults may experience prolonged or recurrent episodes, and the risk of kidney damage is higher.
What Causes IgA Vasculitis?
Although the exact cause is unknown, IgA vasculitis often follows infections, particularly upper respiratory tract infections. Other potential triggers include:
Medications: Such as antibiotics and NSAIDs
Vaccinations: In rare cases, vaccines may act as a trigger
Environmental factors or allergens
Autoimmune reactions: In genetically predisposed individuals
The interplay of genetic and environmental factors likely contributes to the development of the condition, but more research is needed to clarify the mechanisms involved.
Diagnosis and Evaluation
Diagnosis is based on clinical presentation, especially the characteristic rash, and supported by lab tests. Doctors may perform:
Urinalysis: To check for blood or protein indicating kidney involvement
Blood tests: To assess inflammation levels and IgA concentrations
Skin biopsy: To confirm IgA deposition in the blood vessels
Kidney biopsy: In severe cases with suspected nephritis
Prompt and accurate diagnosis is crucial, especially when organs beyond the skin are affected.
Latest Treatment Approaches in 2025
Treatment for IgA vasculitis focuses on managing symptoms and preventing complications. In most pediatric cases, supportive care is sufficient. However, adults or those with significant organ involvement may require more aggressive intervention.
Current treatment strategies include:
Corticosteroids: Such as prednisone, to reduce inflammation and relieve severe joint or abdominal pain
Immunosuppressants: Like azathioprine or cyclophosphamide, used in cases with kidney involvement
Rituximab: A monoclonal antibody showing promise in refractory cases
ACE inhibitors or ARBs: Prescribed to protect kidney function
Researchers in 2025 are also exploring biologic therapies targeting specific immune pathways, with early results indicating improved outcomes in resistant cases. Additionally, better diagnostic tools are helping physicians predict which patients may develop long-term complications.
Living with IgA Vasculitis
Although many cases resolve without lasting damage, follow-up is important, especially for monitoring kidney function. Staying well-hydrated, avoiding non-essential medications that strain the kidneys, and maintaining regular medical checkups can help manage the condition effectively.
