Mày đay viêm mạch do nhiễm vi khuẩn Escherichia coli: Tổng quan tài liệu và báo cáo ca bệnh

Abstract

Urticarial vasculitis is a rare condition characterized by urticarial skin rashes (red, raised, and swollen patches) lasting more than 24 hours, accompanied by hemorrhagic congestion and bleeding due to inflammation of small blood vessels, leaving hyperpigmented patches upon healing. The etiology can be related to infections, medications, autoimmune diseases, malignancies, or idiopathic causes. Escherichia coli (E. coli) is a very rare infectious cause. We report a case of a 7-year-old female presenting with fever, scattered hemorrhagic rash, abdominal pain, acute diarrhea, and joint pain. The patient was diagnosed with urticarial vasculitis - Acute diarrhea due to E. coli and was treated with antibiotics and combined with corticosteroids to manage skin rash and joint pain symptoms. The patient was discharged after 10 days with no complication. Conclusion: Urticarial vasculitis is a rare disease, especially in children. Infection is one of the common cause of vasculitis. Skin biopsy is the gold standard for diagnosis. The most important treatment for urticarial vasculitis is to treat the cause. Corticosteroids, antihistamines, and NSAIDs are supportive medications that improve recurrent skin symptoms and systemic symptoms.
