This study evaluated the effects of low-dose i. v. maxacalcitol (OXAROL<sup>®</sup> OCT) in controlling mild secondary hyperparathyroidism (II° HPT) in chronic hemodialysis patients. Nineteen patients were selected for treatment because of increased parathyroid hormone (PTH) levels de spite administration of vitamin D (VD). The patients consisted of 15 males and 4 females, and were divided into 2 groups based on serum intact-PTH (i-PTH) levels (group I; N=11, 240pg/mL≤i-PTH<360pg/mL, group II; N=8, 360pg/mL≤i-PTH<500pg/mL). After a 2-week wash-out period for oral VD, OCT was given intravenously at a dose of 2.5μg in group I and 5.0μg in group II at the end of dialysis therapy 3 times/week. The dose was adjusted to maintain serum i-PTH levels at 240-500pg/mL and normal calcium (Ca) levels. During the 48-week observation period, serum i-PTH decreased significantly in both groups. Serum Ca levels increased mildly in both groups, but they remained within the normal range. Serum levels of phosphorus, ALP, bone ALP and osteocalcin were not significantly changed in either group. There was no correlation between parathyroid gland volume and i-PTH level. These findings suggest that long-term intravenous treatment with low-dose OCT is a useful strategy for the treatment of mild II° HPT without significant increase of serum Ca.

Ischemic heart disease, cerebral hemorrhage, and cerebral embolus are severe complications seen in patients on maintenance hemodialysis. Hyperlipidemia is one of the risk factors profoundly associated with these complications. We investigated whether the use of polysulfone (PS) hemodialysis membrane improved serum levels of some lipid components in 6 non-DM patients on long-term maintenance hemodialysis. These 6 non-DM patients (one treated with CTA-membrane, 5 with EVAL-membrane) had hyperlipidemia (total cholesterol (TC) 263±17mg/dL, triglyceride (TG) 176±20mg/dL). Three patients were administered 5mg/day of Pravastatin sodium as an anti-hyperlipidemic drug, and one received 20mg/day of the same drug. We measured serum levels of TC, TG, LDL-C, HDL-C, LDL-TG, HDL-TG, Apo-A1, Apo-C3 and other factors before and 1 week after, then 1, 3, 5 and 6 months after the change in hemodialysis membrane. The serum TC level started to decrease after changing the membrane, and it decreased to 212±8mg/dL 3 months after that. Serum levels of LDL-C, Apo-A1 and Apo-C3 had significantly decreased at 6 months after the use of PS-membrane. However, serum levels of HDL-C and TG saw no change after the use of PS-membrane.<br>In addition, we tried to decrease or stop anti-hyperlipidemic drugs 6 months after the change in hemodialysis membrane when serum levels of TC had decreased and remained under 200mg/dL. One of the subjects did not need any drugs associated with hyperlipidemia. Another needed to have an anti-hyperlipidemic drug readministered about 4 months after the drug had been stopped.<br>In the present study, the PS-membrane might improve the hyperlipidemic profiles in patients on long-term hemodialysis. It was suggested that the use of PS-membrane might be available to decrease the dosage of antihyperlipidemia drugs or stop the administration of these drugs in hyperlipidemic patients on maintenance hemodialysis.

The open environment of the eye is continuously subject to an influx of foreign agents that can activate complement. Decay-accelerating factor (DAF), membrane cofactor protein (MCP) and CD59 are regulators that protect self-cells from autologous complement activation on their surfaces. They are expressed in the eye at unusually high levels but their physiological importance in this site is unstudied. In the rat, a structural analogue termed 5I2 antigen (5I2 Ag) has actions overlapping DAF and MCP. In this investigation, we injected F(ab')(2) fragments of 5I2 mAb into the conjunctiva and aqueous humor, in the latter case with and without concomitant blockage of CD59. Massive neutrophilic infiltration of the stroma and iris resulted upon blocking 5I2 Ag activity. Frank necrosis of the iris occurred upon concomitant intraocular blockage of CD59. C3b was identified immunohistochemically, and minimal effects were seen in complement-depleted animals and in those treated with non-relevant antibody. The finding that block-age of 5I2 Ag function in periocular tissues and within the eye causes intense conjunctival inflammation and iritis demonstrates the importance of intrinsic complement regulators in protecting ocular tissues from spontaneous or bystander attack by autologous complement.

AMERICAN JOURNAL OF KIDNEY DISEASES Vol. 37 ( 2 ) page： E14 2001.2

Language：English Publishing type：Research paper (scientific journal) Publisher：W B SAUNDERS CO

A 22-year-old man with subacute necrotizing-encephalomyelopathy (SNE; Leigh's disease) was diagnosed as having progressive renal dysfunction. The clinical diagnosis of Leigh's disease was obtained by the typical central nervous lesions, abnormalities in other organs, and increased lactate concentrations in blood and cerebrospinal fluid. We performed an open biopsy of the right kidney. Light microscopic studies of the renal specimen showed diffuse glomerulocystic kidney (GCK) with tubulointerstitial damage. Electron microscopic examination showed marked swelling and increase in the number of mitochondria of the renal tubular epithelial cells. Therefore, it is suggested that mitochondrial disease seems to play an important role in developing GCK. (C) 2001 by the National Kidney Foundation, Inc.
