dc.description.abstractIncreased systemic inflammation and an impaired immune response are features of adult chronic renal failure (CRF). These patients have increased rates of infection, cardiovascular disease, anemia, and malnutrition. We measured inflammatory and immunological markers in a group of children with pre-dialytic CRF. No prior studies have explored these markers even though children with non-dialysed CRF exhibit similar complications to those seen in adults with CRF. Blood was collected from children with mild, moderate, or severe CRF and an age-matched control group. Functional leukocyte subsets were determined using flow cytometry. Circulating levels of interleukin (IL)-1beta, IL-6, IL-8, IL-12, IL-10, and tumor necrosis factor-alpha were measured using a flow cytometric bead assay. Children with severe CRF showed significantly reduced total white cell count and absolute neutrophil and lymphocyte counts. Absolute numbers of CD3+/CD45RO+ memory T cells and CD3+/CD45RO+/CD62L+ memory Th2 cells were significantly reduced in all CRF groups versus controls. Children with severe CRF showed increased CD11b expression on neutrophils and monocytes. Some patients showed increases in pro-inflammatory cytokines that were not related to their level of residual renal function. As CD11b expression mediates leukocyte adhesion to vascular endothelium, upregulation may contribute to the increased endothelial dysfunction observed in children with CRF. L-selectin mediates extravasation of leukocytes into tissue and homing of peripheral blood lymphocytes to lymph nodes. The reduction in L-selectin may inhibit these actions and predispose patients to increased infection later in life. This is the first study to comprehensively investigate leukocyte functional molecules and inflammatory cytokine profiles in children with pre-dialytic CRF and provides new immunological evidence for the clinical manifestations associated with the disease.en
