Henoch-Schönlein purpura (HSP) is the most common vasculitis in children, with an incidence of approximately 10:100 000 children and a slight male predominance (male-to-female ratio of 1.5:1). Henoch-Schönlein purpura nephritis (HSPN) is the principal cause of morbidity for HSP and 1%-7% of HSPN patients may progress to renal failure or end-stage renal disease.
Immunosuppressive therapy has become the standard treatment in children with HSPN, however the use of these drugs are still mainly in an off-label manner in clinical practice. Tacrolimus, a calcineurin inhibitor, has been recently suggested in the treatment of HSPN in children. However, the evidence-based clinical data are still limited.
Given the potential benefits and unmet need in clinical practice, the purposes of this pilot study were to assess effectiveness and safety of tacrolimus in HSPN children and evaluate the potential impact of CYP3A5.

Immunosuppressive therapy included tacrolimus and prednisone. Tacrolimus treatment was initiated at a dosage of 0.05-0.1 mg/kg/day twice daily and used for at least 6 month. Prednisone was started at 2 mg/kg/day and tapered off gradually after initiation of treatment.

Time frame: within 6 months
clinical symptoms and signs disappeared and proteinuria was less than 4mg/h per m2 body surface area within 6 months.
Time frame: within 6 months
if proteinuria was reduced to 4.1-40mg/h per m2 body surface area within 6 months. A nonresponsive patient was defined if there was no improvement in clinical symptoms or signs 6 months after the therapy of tacrolimus with or without prednisone, or urinary protein remained more than 40mg/h per m2 body surface area.
