          Abstract

          Renal involvement during graft-versus-host disease following haematopoietic cell transplantation for multiple myeloma has never been described. We report a case of a recipient who developed nephrotic syndrome and membranous glomerulonephritis 22 months after the graft and 6 months after cyclosporine withdrawal. Symptoms resolved when immunosuppressive therapy was reinstituted.

          Th1 and Th2 T helper cell subsets affect patterns of injury and outcomes in glomerulonephritis.

          The recognition that human immune responses can be directed by two different subsets of T helper cells (Th1 and Th2) has been an important development in modern immunology. Immune responses polarized by either the Th1 or Th2 subset predominance result in different inflammatory effector pathways and disease outcomes. Many autoimmune diseases are associated with either Th1- or Th2- polarized immune responses. Although these different immune response patterns are relevant to glomerulonephritis (GN), little attention has been paid to the consequences of Th1 or Th2 predominance of nephritogenic immune responses for the pattern and outcome of GN. Unlike other autoimmune conditions, GN results from a variety of different immune responses and has a range of histologic features and immune effectors in glomeruli. This review assesses the data available from studies of experimental and human GN that address the Th1 or Th2 predominance of nephritogenic immune responses and their relevance to the different histopathological patterns and outcomes of GN. In particular, the evidence that Th1-predominant nephritogenic immune responses are associated with severe proliferative and crescentic GN is presented.

            Membranous nephropathy: an IgG4-mediated disease.

            Membranous nephropathy is characterised by the deposition of immunoglobulin, predominantly of the IgG4 subclass, along the epithelial surface of the glomerular-basement membrane. Current models of pathogenesis usually assume in-situ immune-complex formation involving an as yet uncharacterised fixed glomerular antigen. I argue that the properties of IgG4 (inability to fix complement and therefore impaired clearance of IgG4-containing complexes; low affinity and therefore ability for IgG4-containing complexes to dissociate and traverse the glomerular-basement membrane) are compatible with a pathogenic mechanism that involves the deposition of circulating IgG4 immune complexes containing diverse antigens.
