Total Lymphoid Irradiation (TLI) to Prevent Focal Segmental Glomerulosclerosis (FSGS)Recurrence in the Renal Graft

2014-08-27 03:43:28 | BioPortfolio

Summary

The purpose was study the immunosuppression using total lymphoid irradiation plus Csa, MMF and prednisone pretransplant to prevent focal segmental glomerulosclerosis recurrence in the renal graft

Description

Focal and segmental glomerulosclerosis (FSGS) is resistant to treatment with immunosuppressants and after transplant, 40% of such patients have recurrences in renal allograft. The purpose of this trial was to use Total Lymphoid Irradiation (TLI) plus mycophenolate mofetil (MMF), cyclosporine A (CsA) and prednisone (PRED) to prevent recurrence.

Medical and Biotech [MESH] Definitions

A clinicopathological syndrome or diagnostic term for a type of glomerular injury that has multiple causes, primary or secondary. Clinical features include PROTEINURIA, reduced GLOMERULAR FILTRATION RATE, and EDEMA. Kidney biopsy initially indicates focal segmental glomerular consolidation (hyalinosis) or scarring which can progress to globally sclerotic glomeruli leading to eventual KIDNEY FAILURE.

Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (UHBI) or lower hemibody irradiation (LHBI). Less common is mid-body irradiation (MBI). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with WHOLE-BODY IRRADIATION. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (P. Rubin et al. Cancer, Vol 55, p2210, 1985)

An ApoL protein highly expressed by the liver. It has anti-trypanosomal activity through its ability to permeabilize TRYPANOSOMA membranes. Mutations in the APOL1 gene are associated with type 4 FOCAL SEGMENTAL GLOMERULOSCLEROSIS .

A non-receptor protein-tyrosine kinase that is expressed primarily in the BRAIN; OSTEOBLASTS; and LYMPHOID CELLS. In the CENTRAL NERVOUS SYSTEM focal adhesion kinase 2 modulates ION CHANNEL function and MITOGEN-ACTIVATED PROTEIN KINASES activity.

A non-selective, calcium permeant TRPC cation channel that contains four ANKYRIN REPEATS and is activated by DIACYLGLYCEROL independently of PROTEIN KINASE C. It is expressed in placenta, lung, spleen, ovary and the small intestine, as well as by PODOCYTES in the kidney glomerulus. Mutations in the TRPC6 gene are associated with FOCAL SEGMENTAL GLOMERULOSCLEROSIS type 2.
