A case of early recurrent immunoglobulin A nephropathy and T-cell-mediated rejection in a transplant patient with Wiskott-Aldrich syndrome.

CEN Case Rep 2021 Jul 25. Epub 2021 Jul 25.

Department of Nephrology, Nagasaki University School of Medicine Graduate School of Biomedical Sciences, 1-7-1 Sakamoto, Nagasaki, 852-8501, Japan.

Wiskott-Aldrich syndrome (WAS) is an X-chromosome recessive immunodeficiency disease characterized by the triad of thrombocytopenia, eczema, and susceptibility to infection owing to WAS protein gene abnormalities. Kidney transplantation is rarely offered to WAS patients with end-stage renal disease because of concerns that thrombocytopenia and immune disorders may affect the clinical outcome. Here, we report the case of a 20-year-old kidney transplant patient who developed end-stage renal disease owing to immunoglobulin (Ig)A nephropathy caused by WAS. Read More
