IgA vasculitis-induced testicular ischemia in a pediatric patients

Description

IgA vasculitis, formerly known as Henoch-Schönlein purpura, is a systemic vasculitis primarily affecting children. It is characterized by the deposition of IgA immune complexes in small blood vessels, leading to a range of clinical manifestations, including purpuric skin rash, joint pain, abdominal pain, and renal involvement. While IgA vasculitis primarily affects the skin, joints, and kidneys, it can also involve other organs, including the testicles. It gives a rare occurrence of testicular ischemia associated with IgA vasculitis in a child, emphasizing the importance of recognizing and managing this potentially serious complication.

The testicular ischemia in IgA vasculitis occurs due to inflammation and damage to the blood vessels that supply blood to the testicles. As a result, the blood flow to the testicles is reduced, leading to insufficient oxygen and nutrients, which can have serious consequences. The most common and noticeable symptom is severe pain and swelling in one or both testicles. The pain can be sudden and excruciating, and it may be associated with redness and warmth of the scrotal area. Some people may develop a rash or bruising on the scrotal skin, which can be a result of inflammation and bleeding in the affected area. A low-grade fever may accompany the testicular symptoms, indicating the presence of systemic inflammation.

IgA vasculitis-induced testicular ischemia typically involves a combination of clinical evaluation and imaging studies. A thorough physical examination, including a detailed examination of the scrotum, is crucial to assess the extent of testicular involvement. Ultrasound imaging of the scrotum can confirm the diagnosis by showing reduced blood flow to the affected testicle(s). It can also rule out other potential causes of testicular pain. Blood tests can help identify markers of inflammation and assess kidney function, as IgA vasculitis can also affect the kidneys.

Severe pain is a common symptom and should be managed promptly with pain-relieving medications. High-dose corticosteroids, such as prednisone, are often prescribed to reduce inflammation and control the autoimmune response. In cases of severe testicular involvement or persistent symptoms, immunosuppressive medications may be necessary to dampen the immune response. Intravenous fluids may be administered to maintain hydration, and bed rest may be recommended to alleviate discomfort. Regular follow-up appointments are essential to monitor progress, adjust medications, and assess kidney function. With timely diagnosis and appropriate treatment, most pediatric patients with IgA vasculitis-induced testicular ischemia recover without long-term complications. However, delayed treatment can lead to permanent testicular damage, potentially affecting fertility.

Testicular involvement in IgA vasculitis is a rare but serious complication that can lead to testicular ischemia and even testicular infarction. The pathogenesis of testicular involvement in IgA vasculitis is not entirely understood but is thought to involve the deposition of IgA immune complexes in the testicular blood vessels, leading to vasculitis and impaired blood flow.

Recognition of testicular involvement in IgA vasculitis is crucial as delayed diagnosis and treatment can result in irreversible testicular damage. Doppler ultrasound is a valuable diagnostic tool for assessing testicular blood flow and detecting ischemia. Urgent surgical exploration may be required if testicular torsion is suspected, as was the case in our patient. In addition to surgical intervention, prompt initiation of systemic therapy with corticosteroids and IVIG is essential to treat the underlying IgA vasculitis and prevent further vascular damage.
