Immediate effect of Shakuyaku-kanzo-to on muscle cramp in hemodialysis patients.

We administered 2.5 g of Shakuyaku-kanzo-to granule to 61 patients who had muscle cramp during hemodialysis (HD) sessions and examined its immediate effects. We selected 10 patients who wanted to take the drug at home, out of cases, for whom the drug was effective on the study described above and had them take the drug in the same way at the beginning of muscle cramp at home examined the effects. In the study during HD sessions, muscle cramp and its associated pain disappeared in 5.3 +/- 3.9 min on average in 54 out of 61 cases. In the study of patients who took the drug at home, muscle cramp disappeared within 10 min in all cases. Shakuyaku-kanzo-to is thought to be very useful for muscle cramp during HD sessions of hemodialized patients because it has immediate effects by its oral administration on the occasion of cramp. With regard to the muscle cramp, which appears at home after HD sessions, the patients can cope with it by taking the drug by themselves. This is an epoch-making therapy, for it was impossible to cope with muscle cramp except in hospitals because the therapy of muscle cramp was limited to intravenous infusion of hypertonic solutions of dextrose, mannitol, and saline during HD sessions.

[Treatment of adynamic bone disease with the complete replacement from calcium carbonate to sevelamer hydrochloride].

The aim of this study was to examine the therapeutic effect of hypocalcemic stimulation caused by sevelamer hydrochloride (SH) administration on adynamic bone disease (ABD). The subjects were 28 maintenance hemodialysis (HD) patients who had remained in ABD state in spite of no administration of vitamin D(3) since HD induction (15 males and 13 females;12 diabetic patients and 16 non-diabetic patients). The mean age was 61.8+/-9.5 years and the mean HD duration was 5.5+/-3.9 years. The calcium concentration in the dialysate was 3.0 mEq/L. We made the final daily dose of SH after two months the same as the first daily dose of calcium carbonate (CC) in the following manner. At first we administered only CC at breakfast and lunch and SH at supper. And for the next two weeks we administered CC at breakfast and SH at lunch and supper. And for the final two weeks we administered only SH. After that we increased the dose of SH as much as possible. We evaluated the therapeutic effect of the above treatment on ABD using intact-osteocalcin (iOC) [Teijin. Tokyo] as a marker before and 6, 12 months after the beginning of the replacement. If iOC Ievel of 30 to 70 ng/mL showed normal tumover bone (NTB), 5 cases (17.9%) changed into NTB in 6 months. 9 cases (32.1%) changed into NTB in 12 months and one case (3.6%) changed into ostitis fibrosa in 12 months. It is thought that SH is effective for the treatment of ABD but we have to be careful for ostitis fibrosa.

Dialysis and quality of dialysate in southeast asian developing countries.

BACKGROUND: The number of dialysis patients has been increasing in Southeast Asia, but statistical data about these patients and on the quality of dialysates in Southeast Asian dialysis facilities are still imprecise. For this study, dialysis-related statistical data were collected in Southeast Asia. METHODS: A survey of the quality of dialysates was carried out at 4 dialysis facilities in Vietnam and Cambodia. The dialysis patient survey included the numbers of dialysis facilities and patients receiving dialysis, a ranking of underlying diseases causing the initiation of dialysis, the number of patients receiving hemodialysis (HD)/on-line hemodiafiltration/continuous ambulatory peritoneal dialysis, the number of HD monitoring devices installed, the cost of each session of dialysis (in USD), the percentage of out-of-pocket payments, and the 1-year survival rates of the dialysis patients (in percent). The dialysate survey covered the endotoxin (ET) level and bacterial count in tap water, in water filtered through a reverse osmosis system and in dialysate. RESULTS: In each of the countries, the most frequent reason for the initiation of dialysis is diabetes mellitus. HD is usually carried out according to the 'reuse' principle. The 1-year survival rates are 70% in Myanmar and about 90% in the Philippines and Malaysia. The ET levels in standard dialysates were satisfactory at 2 facilities. The bacterial counts in dialysates were not acceptable at any of the facilities investigated. CONCLUSION: There is an urgent need to teach medical workers involved in dialysis how to prepare sterile and ET-free dialysates.
