Low-density lipoprotein apheresis for focal glomerular sclerosis.

We report on a 22-year-old female with focal glomerular sclerosis and hyperlipidemia who did not respond to long-term steroid or immunosuppressant therapy. When low-density lipoprotein (LDL) apheresis was performed, her total daily protein excretion decreased, serum albumin increased, total cholesterol decreased from 1,052 mg/dl to 148 mg/dl after 3 months, and the serum lipoprotein(a) level also decreased from 117.8 mg/dl to 9.

Remnant-like particle cholesterol may indicate atherogenic risk in patients on chronic hemodialysis.

Recently, involvement of remnant-like particle cholesterol (RLP-C) in atherosclerosis was reported, but this parameter has not been adequately investigated in hemodialysis (HD) patients. The present study investigated the relationship between the RLP-C level and total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), lipid peroxides (malone dialdehyde, MDA), apolipoprotein (Apo) A-I, and ApoB. In addition, the fractions of very low density lipoprotein (VLDL), intermediate density lipoprotein (IDL), LDL, and HDL in serum lipoproteins were determined by disk polyacrylamide gel electrophoresis.

Involvement of bacterial antigens in immunoglobulin A nephropathy.

To investigate the involvement of bacterial antigens in Immunoglobulin A (IgA) nephropathy, we measured IgA, IgG and IgM antibodies to gram-negative Escherichia coli (E.coli) and Haemophilus influenzae (H.influenzae) by ELISA in 24 patients (11 males and 13 females) with IgA nephropathy and 22 normal controls (11 males and 11 females).
