Comparative Study Clinical Trial
Different pattern of fluid loss from the lower extremities in normohydrated and overhydrated stage 5 chronic-kidney-disease patients after haemodialysis.
It is unclear whether fluid is lost from each body segment in a similar manner during haemodialysis (HD) in normohydrated (NH) and overhydrated (OH) patients. ⋯ NH and OH patients show different patterns of fluid loss from regional-body fluid compartments. This may be useful for determining patient hydration status.

Hypertension is one of the risk factors for cardiovascular diseases. The kidneys could be a victim and/or culprit of hypertension. Recently, the value of neutrophil gelatinase-associated lipocalin (NGAL) was highlighted as a novel marker for early detection of acute renal damage. Therefore, the aim of the study was to assess whether hypertension could affect NGAL and cystatin C levels in patients with normal serum creatinine (lower than 1.5 mg/dL in males and 1.2 mg/dL in females) and stable coronary artery disease. ⋯ Hypertension is associated with kidney injury as reflected by elevated serum NGAL and cystatin C. It is noteworthy that despite normal serum creatinine, eGFR is relatively low suggesting impaired renal function. Therefore, NGAL needs to be investigated as a potential early marker for impaired kidney function/kidney injury, especially in patients with another risk factor for kidney damage, namely coronary artery disease.

Comparative Study
Beneficial effect of neutrophil elastase inhibitor on anti-Thy1.1 nephritis in rats.
Neutrophil elastase, one of the proteinases released by neutrophils, plays an important role at the sites of inflammation and was reported to be involved in the pathogenesis of glomerulonephritis. Sivelestat is a selective neutrophil elastase inhibitor used for acute lung injury associated with systemic inflammatory response syndrome. There have been few reports on the effects of sivelestat on renal disease. ⋯ Neutrophil elastase is suggested to be involved in the development of anti-Thy1.1 nephritis, and the neutrophil elastase inhibitor sivelestat reduces the tissue injury of anti-Thy1.1 nephritis in rats.

Acute pyelonephritis is a common infectious disease in children and can result in permanent renal damage. Interleukin (IL)-1beta is an important inflammatory mediator that appears early during bacterial infection. This prospective study examined urine IL-1beta levels in children with acute pyelonephritis documented by (99m)Tc-dimercaptosuccinic acid (DMSA) scan, and also evaluated whether this cytokine correlated with renal scarring. ⋯ These results have shown that urine IL-1beta level may serve as a useful marker for the early detection of acute pyelonephritis in febrile children. Young children are at a risk of the development of renal scarring following acute pyelonephritis.

Urinary tract infection (UTI) is one of the most common causes of unexplained fever in infants with a reported prevalence range of 5-11%. The clinical and laboratory findings were reviewed, and diagnosis and treatment for 95 infants with primary UTI were evaluated in this study. ⋯ Four weeks of antibiotic treatment resulted in good recovery from pyelonephritis in the present sample of infant primary UTI cases. voiding cystourethrogram, DMSA and ultrasonography scanning should be performed in primary infant UTI.
