22,23) In this study, pre-transplant PRA level was found to have no value in predicting either the antibody-mediated rejection or C4d deposition on peritubular capillaries.
C4d staining should be assessed in peritubular capillaries of nonatrophic renal parenchyma (Figure 1, A and B), either cortex or medulla; an adequate sample is currently defined as 5 high-power fields.
An urgent biopsy showed moderate glomerulitis and the presence of inflammatory cells in peritubular capillaries, but C4d was negative.
The renal artery small branching order afferent arterioles lead to the glomerular capillaries and the distal ends of the capillaries of each glomerulus join together to form the efferent arterioles, followed by a second capillary network constituted by the peritubular capillaries surrounding renal tubules.
Other recent studies have also showed mononuclear cells in glomerular and peritubular capillaries though the number of leukocytes was not significantly different between the ARF group and the non-ARF group (62,63).
Methods: Renal biopsies from 16 patients with lupus nephritis were reviewed for C4d deposition in the glomeruli and peritubular capillaries.
Several pathways exist for the movement of ions and water between the tubule and the peritubular capillaries.
The US Food and Drug Administration approved agalsidase beta in 2001 following a clinical study in which a reduced amount of GL-3 inclusions in endothelial cells of renal peritubular capillaries (PTCs) was demonstrated after a period of intermittent intravenous treatment with this recombinant enzyme.
Superficial nephrons have short loops of Henle that extend only to the outer medullary layer, and their efferent arterioles brandl into peritubular capillaries that surround the nephron segments.
a) For kidney studies, only staining of peritubular capillaries was considered for this summary.
In the cortex, the peritubular capillaries form a network surrounding nephron segments located within the cortex.
In particular, the neoplastic lymphocytes were present in the peripheral blood, and the lymphomatous infiltrate in the kidney involved both the glomerular and peritubular capillaries simultaneously.
