PCH

No specific treatment exists for cases when the cause is unknown. Cases caused by syphilis respond to treatment for the underlying disorder.

Many cases will resolve without treatment. In some people, the attacks may occur repeatedly for many years.

• Recurrence of attacks
• Severe anemia
• Kidney failure

Call your health provider if symptoms of this disorder develop (to rule out other causes of the symptoms, and to determine if treatment is needed).
