[A case of thrombotic microangiopathy with glomerular subendothelial IgA deposition due to bevacizumab].

Bevacizumab, an inhibitor of vascular endothelial growth factor, is approved for the treatment of various cancers, but the incidence of proteinuria as a side effect has been reported to be 2-64%. We report a case of renal impairment due to thrombotic microangiopathy (TMA) accompanied with glomerular subendothelial deposition of IgA resulting from bevacizumab administration. A 57-year-old female with advanced breast cancer, to whom bevacizumab had been administered from October 2012, developed proteinuria and epithelial casts in her urine about a month later.

The evaluation of filtration coefficients of microvasculature for the assessment of fluid status in hemodialysis patients.

Purpose: Bioimpedance spectroscopy (BIS) is widely used to assess fluid status in hemodialysis (HD) patients. Our purpose is to evaluate filtration coefficients (Lpst) as an alternative test to assess fluid status by utilizing BIS as a reference test.


Methods: 106 HD patients (determined group) were divided into two groups with (EX group: 53) or without excess fluid mass (ExF).

Evaluation of estimated creatinine clearance before steady state in acute kidney injury by creatinine kinetics.

Background: A simple method to calculate estimated creatinine clearance using two serum creatinine concentration (Cr) values in acute kidney injury (AKI) was developed (eCrCl-AKI). We aimed to evaluate its accuracy and to clarify its contribution to the classification of AKI.

Methods: We validated the errors in eCrCl-AKI in a simulation study after various reductions in creatinine clearance (CrCl) at various levels of chronic kidney disease (CKD).

Drosophila carrying pex3 or pex16 mutations are models of Zellweger syndrome that reflect its symptoms associated with the absence of peroxisomes.

The peroxisome biogenesis disorders (PBDs) are currently difficult-to-treat multiple-organ dysfunction disorders that result from the defective biogenesis of peroxisomes. Genes encoding Peroxins, which are required for peroxisome biogenesis or functions, are known causative genes of PBDs. The human peroxin genes PEX3 or PEX16 are required for peroxisomal membrane protein targeting, and their mutations cause Zellweger syndrome, a class of PBDs.

Discrepancy between cystatin C and creatinine points leading to a diagnosis of postrenal acute kidney injury and its reversibility: three case reports.

We report on three patients with postrenal acute kidney injury (AKI) showing a remarkably low level of cystatin C (CysC) compared with that of creatinine (Cr). The levels of Cr and CysC (Cr/CysC) were respectively as follows: 12.16 mg/dl/1.
