Interleukin 8 Is Overexpressed in Acute Rejection in Kidney Transplant Patients.

The main complication associated with renal graft loss is immune rejection. The gold standard for the diagnosis of renal graft rejection is percutaneous renal biopsy, which is expensive and can lead to complications. Inflammation is one of the main pathogenic pathways in allograft rejection, and urine samples seem to be efficient windows to explore the allograft condition with a high cost-benefit ratio.

Analyses of Programmed Cell Death Protein 1 in High Immunologic-Risk Transplant Patients.

Kidney transplant (KT) is the first therapeutic option for most patients with chronic renal failure that requires renal function replacement. The main complication associated with renal graft loss is immune rejection. The T regulatory pathways play a key role in this process, and abnormalities in some of these molecules could participate in the graft rejection.

Objectives: Alexithymia is a personality trait related to the quality of life of women with fibromyalgia (FM). It is still unknown whether alexithymia is associated with the clinical manifestations of FM.
