[Relationship between serum uric acid levels and muscle strength/volume: a new insight from a large-scale survey].

Aim: Serum uric acid (UA) concentration is regulated by its production in the liver and/or intestine and its rate of excretion from the kidneys. However, little is known about skeletal muscle involvement in determining the physiological UA level. The present trial explores whether muscle strength and/or muscle volume is associated with UA levels.

[Study on the predictors for superimposed preeclampsia in patients with IgA nephropathy].

Objective: Pregnancy in chronic kidney disease (CKD) patients is often associated with hypertension and/or the worsening of renal function and neonatal death. The present study explored the clinical characteristics of predictive factors for hypertension in biopsy-proven IgA nephropathy patients with superimposed preeclampsia (SPE).

Patients And Methods: The subjects were 34 Japanese women with IgA nephropathy whose renal specimen for histological tests was obtained before pregnancy.

[Crescentic and necrotizing glomerulonephritis with C3 deposition].
