Autoimmune thyroiditis in association with membranous nephropathy.

Hashimoto's thyroiditis and membranous nephropathy are believed to be mediated by immune mechanisms. A 12 year-old patient is reported who presented with fatigue, dislike of cold, pallor and growth retardation. Initial laboratory assessment showed moderate proteinuria and impaired renal function (serum creatinine 2.

Mutant chromatin remodeling protein SMARCAL1 causes Schimke immuno-osseous dysplasia.

Schimke immuno-osseous dysplasia (SIOD, MIM 242900) is an autosomal-recessive pleiotropic disorder with the diagnostic features of spondyloepiphyseal dysplasia, renal dysfunction and T-cell immunodeficiency. Using genome-wide linkage mapping and a positional candidate approach, we determined that mutations in SMARCAL1 (SWI/SNF2-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a-like 1), are responsible for SIOD. Through analysis of data from persons with SIOD in 26 unrelated families, we observed that affected individuals from 13 of 23 families with severe disease had two alleles with nonsense, frameshift or splicing mutations, whereas affected individuals from 3 of 3 families with milder disease had a missense mutation on each allele.

Recipient age and weight affect chronic renal allograft rejection in rats.

Nephron doses and immune responses change with age. Therefore, age is a potential risk factor for graft survival after kidney transplantation. The aim of this study was to determine whether age-related differences are of importance for long-term outcomes after renal transplantation.
