Patient's question:
In November 2011, purpura appeared on both lower limbs, and urine occult blood was positive. After treatment with traditional Chinese medicine, the purpura disappeared. It has persisted ever since.At the end of December 2012, purpura reappeared on both lower limbs, and the patient was admitted to the Pediatrics Department of Yangquan No. 1 People's Hospital. The patient was discharged on January 18, 2013.
After discharge, the patient underwent weekly urine routine tests, and the occult blood result remained one plus (+) throughout.
Recently, the patient had a cold and cough, and today's reexamination showed one plus (+) for occult blood and one plus (+) for protein, with microalbumin greater than 0.15.
Doctor's answer:
Allergic purpura is a systemic disease characterized by necrotizing vasculitis as the primary pathological change, which can affect multiple organs in the body, including kidney damage. Clinical manifestations include skin purpura, joint swelling and pain, abdominal pain, and hematuria. The main symptoms are hematuria and proteinuria, which typically occur within one month after the onset of skin purpura. Some patients may experience both skin purpura and abdominal pain simultaneously, while others may only have asymptomatic urinary abnormalities. Treatment can be managed through routine examinations and initial therapy combined with the doctor's experience, avoiding renal biopsy. Renal biopsy may be considered only if the treatment is completely ineffective.
