Growth in children with chronic kidney disease and associated risk factors for short stature.

Introduction: Growth failure in chronic kidney disease is related to high morbidity and mortality. Growth retardation in this disease is multifactorial. Knowing the modifiable factors and establishing strategies to improve care for affected children is paramount.

Dialysis-related thrombocytopenia: a case report.

Thrombocytopenia is frequently observed in hemodialysis patients, and its correct investigation and control remain a challenge. It is estimated that during the hemodialysis session there is a drop of up to 15% in the platelet count, with recovery after the end of treatment. This reduction in platelets is due to platelet adhesion and complement activation, regardless of the membrane material.

Comparison of serum levels with bone content and gene expression indicate a contradictory effect of kidney transplantation on sclerostin.

In an attempt to clarify the mechanisms of post-transplant bone disease we investigated the bone content and gene expression of several bone-related proteins. After a successful kidney transplant, the content of sclerostin in bone biopsies was found to be increased as measured by immunohistochemistry, multiplex assay, and gene expression despite a concomitant decrease of sclerostin in the serum. The phosphorylation of beta-catenin was increased, confirming Wnt pathway inhibition, an effect accompanied by an increase of the receptor activator of nuclear factor kappa-Β ligand (RANKL) and a decrease of osteoprotegerin protein levels in both serum and bone.

Obstetric outcome in pregnant women on long-term dialysis: a case series.

Background: Although still uncommon, pregnancy frequency in women on maintenance hemodialysis therapy has increased in the past 20 years. Most published reports suggest that intensified hemodialysis regimens result in better pregnancy outcomes. The small number of patients investigated in all reported series is the main limitation of the available studies.

Positive acute-phase inflammatory markers in different stages of chronic kidney disease.

Background: An elevated serum level of acute-phase inflammatory markers is associated with an increased risk of cardiovascular disease. We hypothesized that elevated acute-phase inflammatory markers are directly associated with the different stages of chronic kidney disease (CKD).

Methods: We evaluated the relationship between serum levels of high-sensitivity C-reactive protein (hsCRP) and alpha1-acid glycoprotein (alpha1-AGP), as well as the renal function in 224 adult patients with CKD (mean age 56.
