A Kidney Transplant Recipient with Recurrent Henoch-Schönlein Purpura Nephritis Successfully Treated with Steroid Pulse Therapy and Epipharyngeal Abrasive Therapy.

There is no specific treatment for recurrent Henoch-Schönlein purpura nephritis (HSPN) in a transplanted kidney. We herein report a case of a kidney transplant recipient with recurrent HSPN that was successfully treated with steroid pulse therapy and epipharyngeal abrasive therapy (EAT). A 39-year-old Japanese man developed HSPN 4 years ago and had to start hemodialysis after 2 months despite receiving steroid pulse therapy followed by oral prednisolone, plasma exchange therapy, and cyclophosphamide pulse therapy.

Improvement of Alveolar Hemorrhaging in an Elderly and Renally Impaired Patient with Relapsing Anti-neutrophil Cytoplasmic Autoantibody-associated Vasculitis by Single Infusion of Rituximab.

Rituximab (RTX) has become a therapeutic option for inducing remission of anti-neutrophil cytoplasmic autoantibody-associated vasculitis (AAV). However, the optimum dosage of RTX to induce remission of AAV and reduce adverse events, such as infection, remains unclear. We herein report an elderly and renally impaired patient with alveolar hemorrhaging due to refractory AAV who was successfully treated with single infusion of RTX.

Spontaneous remission of adult-onset minimal change nephrotic syndrome associated with influenza B infection: a case report.

Background: While the majority of adult-onset minimal change nephrotic syndrome (MCNS) is a primary or an idiopathic form of disease, it can also occur as a secondary form. Reports on the spontaneous remission of MCNS are rare since the condition is typically treated with corticosteroids. We herein describe the spontaneous remission of adult-onset MCNS in a patient who developed nephrotic syndrome after type B influenza infection.

Granulomatous interstitial nephritis due to chronic lymphocytic leukemia: a case report.

Background: Renal failure due to the infiltration of chronic lymphocytic leukemia (CLL) cells into the tubulointerstitial area of the kidney is uncommon. Furthermore, granulomatous interstitial nephritis (GIN) is a rare histological diagnosis in patients undergoing a renal biopsy. We herein report a case of GIN due to the diffuse infiltration of CLL cells in a patient who developed progressive renal failure.
