Question

About a fortnight ago, purple-red spots appeared on the lower legs. After six days of injection treatment, there was a significant improvement, but they recurred two days later.

Answer

For patients with refractory chronic nephritis, options include the use of cyclophosphamide or azathioprine, which can be used in combination with corticosteroids. For symptomatic treatment, patients with fever and joint pain can use antipyretic analgesics such as indomethacin or Fenbid; for abdominal pain, oral or intramuscular atropine can be administered.
