What are the complications of Henoch-Schnlein Purpura ?
In children, the risk of kidney damage leading to long-term problems may be as high as 15 percent, but kidney failure affects only about 1 percent of children with HSP.1 Up to 40 percent of adults with HSP will have CKD or kidney failure within 15 years after diagnosis.3
                
A rare complication of HSP is intussusception of the bowel, which includes the small and large intestines. With this condition, a section of the bowel folds into itself like a telescope, causing the bowel to become blocked.
                
Women with a history of HSP who become pregnant are at higher risk for high blood pressure and proteinuria during pregnancy.
