Henoch-Schonlein Purpura Explained: An Overview of This Immune System Disorder

Henoch-Schonlein Purpura (HSP), also known as IgA vasculitis, is a small-vessel vasculitis that primarily affects children but can also occur in adults. This condition is characterized by the inflammation of small blood vessels, leading to symptoms such as a purplish skin rash, joint pain, abdominal pain, and kidney involvement.

HSP is relatively common in children, particularly those between the ages of 2 and 6, with around 10 to 20 cases occurring per 100,000 children each year. The disease is more prevalent in males than females and tends to occur more frequently during the fall and winter months, often triggered by an infection, such as a respiratory or gastrointestinal infection.

The common comorbidities of HSP are predominantly renal disease, gastrointestinal complications, joint inflammation, central nervous system vasculitis, pulmonary hemorrhage, and urologic involvement. Gastrointestinal complications are frequent and include small bowel intussusception, gastrointestinal hemorrhage, and small bowel infarction. Renal involvement, or HSP nephritis, can range from mild proteinuria to severe crescentic glomerulonephritis and renal failure, and is a critical determinant of prognosis. Joint involvement typically manifests as a migratory oligoarticular arthritis presenting with joint pain and swelling, often in knees and ankles. Central nervous system involvement, pulmonary involvement, and urologic involvement are less common but serious, and can lead to a range of symptoms.

In some cases, severe skin manifestations like intense subcutaneous edema may occur, and obesity has been associated with more severe clinical courses in children with HSP. It is important to note that HSP is associated with the deposition of IgA antibodies in the blood vessels, and a skin biopsy may be performed to confirm the presence of IgA deposits.

Treatment for HSP primarily focuses on managing symptoms and preventing complications, with most cases resolving on their own without the need for aggressive treatment. In mild cases, treatment may be primarily symptomatic, including pain relief, hydration, and rest. In severe cases or when kidney involvement is present, corticosteroids, immunosuppressants, or other medications may be necessary.

Regular follow-up appointments are crucial for monitoring the patient's condition, especially for those with kidney involvement. Blood tests may include tests for kidney function, inflammatory markers, and IgA levels. Urinalysis checks for blood and protein in the urine, indicating kidney involvement.

Living with HSP requires a proactive approach to management, including regular check-ups, medication, rest, hydration, and dietary considerations. Seeking support from mental health professionals or joining support groups can help manage the emotional and psychological impact of living with a chronic condition like Purpura.

Long-term complications of Purpura may include chronic kidney disease and hypertension. It is important for those affected by HSP to work closely with their healthcare providers to manage their condition effectively and prevent long-term complications.
