Henoch-Schonlein purpura nephritis occurring postpartum in a patient with anti-PL-7 anti-synthetase syndrome

摘要

A 37-year-old pregnant woman developed purpura which was subsequently diagnosed as Henoch-Schonlein purpura (HSP). After childbirth, the patient developed proteinuria and hematuria. Further examination revealed that the HSP nephritis (HSPN) was associated with anti-threonyl-tRNA synthetase anti-synthetase syndrome. The onset of HSPN during pregnancy or after childbirth is rare. Moreover, to our knowledge, this is the first case to describe renal involvement in anti-synthetase syndrome.
