Randomized Controlled Trial Multicenter Study
Lanthanum carbonate effectively controls serum phosphate without affecting serum calcium levels in patients undergoing hemodialysis.
Treating hyperphosphatemia without increasing the calcium load in chronic kidney disease patients on dialysis is important, as conventional treatment frequently results in ectopic calcification. Sevelamer, a monotherapy for hyperphosphatemia is frequently associated with gastrointestinal disorders, often resulting in discontinuation of treatment. Lanthanum carbonate is a novel non-calcium-based phosphate binder for the treatment of chronic kidney disease. ⋯ The incidence of drug-related adverse events was dose-dependent, with the most common being gastrointestinal symptoms. Lanthanum carbonate effectively controls serum phosphate levels and is generally tolerable to Japanese chronic kidney disease patients on dialysis, as reported for the Caucasian population. The optimal dosage in Japanese patients needs to be confirmed using a flexible-dose titration schedule.

Randomized Controlled Trial Clinical Trial
Control of parathyroid function in patients with a short history of hemodialysis.
Secondary hyperparathyroidism (SHPT) is one of the serious complications in patients with chronic kidney disease. Parathyroid glands secrete parathyroid hormone (PTH), stimulated partly by hyperphosphatemia and hypocalcemia complicating chronic kidney disease (CKD). Use of a calcium-based phosphate binder might be sufficient to reduce serum PTH levels in mild SHPT, while the recent K/DOQI clinical guidelines recommended vitamin D therapy for dialysis patients with serum level of intact parathyroid hormone of 300 pg/mL or more. ⋯ The other effects of the two regimens on the secondary end points were not significantly different after 6 months. In SHPT of dialysis patients initiating hemodialysis, oral calcium carbonate use alone was not inferior to additional vitamin D sterol use with calcium carbonate in reducing serum PTH levels. Our result indicated that, if serum calcium and phosphorus levels are controlled primarily regardless of used agents, it will be followed by reduction of serum PTH level in these patients.

Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy and safety of the new heparin-induced extracorporeal low-density lipoprotein precipitation system (Plasmat Futura) in comparison with the currently used system (Plasmat Secura).
The aim of the present study was to examine whether the recently introduced heparin-mediated extra-corporeal low-density lipoprotein precipitation (HELP) apheresis system Plasmat Futura (since 2001) was comparable to Plasmat Secura system, used to date, in its efficiency to remove atherogenic components, its ease of handling and operating as well as clinical safety and patient compliance. Coronary heart disease (CHD) patients (N = 21) were first treated with Plasmat Secura system and 13 of them were then randomly switched over to the upgraded Plasmat Futura system. Eight patients remained on Secura system. ⋯ Long-term tolerance and safety parameters showed no significant difference (P > 0.05). On the basis of our studies. Plasmat Futura system is easy to use, shows no adverse events and is comparable to Plasmat Secura in its capacity to remove proatherogenic plasma factors.
