Effect of clofibrate on plasma lipid concentration and liver malic enzyme gene expression in rats with experimental chronic renal failure.

Fibrates have been used clinically to treat dyslipidemias, including chronic renal failure (CRF)-related hypertriacylgliceridemia. In addition to their effects on plasma triacylglycerol concentration, fibrates also induce hepatomegaly (due to peroxisome proliferation) and increase liver malic enzyme activity. Since most experiments regarding fibrates action have been performed on healthy animals, in this paper we compare the effect of clofibrate on: a) plasma lipid concentration; b) liver weight; c) liver malic enzyme gene expression (malic enzyme activity, malic enzyme protein level and malic enzyme mRNA abundance) in control (sham-operated) animals and rats with CRF. The data presented in this paper indicate that: a) the clofibrate treatment causes a decrease in triacylglycerol concentration both in the control and rats with CRF, however the effect of the drug was more pronounced in the latter; b) administration of clofibrate induces hepatomegaly both in the control and rats with CRF; c) the liver malic enzyme gene expression is similarly affected by clofibrate in the control and rats with CRF. It is concluded that the beneficial, therapeutic effect of clofibrate on plasma lipid concentration is more pronounced in rats with CRF, but the side effects (hepatomegaly and the increase in malic enzyme gene expression) of fibrates are essentially similar in the control and rats with CRF.

[Clinical estimation of 1-alpha-hydroxycholecalciferol in treatment of patients with chronic renal failure].

31 adult patients (15 male and 16 female) with chronic renal failure were treated for 6 months with 1-alfa-hydroxycholecalciferol on a dose 0.25-2.0 micrograms/24 h. 15 patients with not very advanced renal failure (serum creatinine level 176.8-442 mumol/l) received conservative therapy (group I), 16 patients with serum creatinine value 884-1326 mumol/l were treated by intermittent hemodialysis (group II). The statistically significant decrease of serum alkaline phosphatase activity in group I and II (p < 0.01), the rise of serum calcium level in group I (p < 0.005) were determined. Half of the patients from both the groups stated the relief or disappearance of bone and joint pains and muscle weakness. Besides in group I significant decrease of creatinine clearance (p < 0.001) and increase of serum urea and creatinine value (p < 0.01) were noticed. On the basis of these results we can conclude that the treatment with 1-alfa-hydroxycholecalciferol, produced by "Polfa", ought to be introduced gradually with increasing doses and frequent monitoring of calcium-phosphate metabolism and renal function parameters.

[Evaluation of the effect of d,l-carnitine on lipid metabolism of patients after prolonged dialysis].

An effect of carnitine (Bicarnesine) on lipid metabolism in 14 patients treated with prolonged dialyses has been analysed. Carnitine has been administered orally in the dose of 30 mg/kg b.w. three times per week for 8 weeks and every day for the next 8 weeks. Carnitine, total triglycerides, total and HDL cholesterol, and glucose have been determined in serum. Blood lipoproteins have been assayed with electrophoresis in agarose gel. Total and free carnitine concentrations increased by 3.5 times within 16 weeks. Triglycerides level did not change significantly in all examined patients except a group of 6 patients with baseline hypertriglyceridemia, in which a significant but transient decrease in triglycerides level has been noted after 4 weeks of treatment. At the same time, normalization of blood lipoproteins has been observed. In the eighth week, a transient decrease in HDL-cholesterol has been noted. Result suggest, that carnitine despite an increase in total and free carnitine blood levels did not regulate lipid metabolism disorders. Moreover, its administration to patients treated with prolonged dialyses seems to be unfavourable due to several adverse reactions.

[Nephrotoxicity of gentamycin used in hepatic and biliary diseases].

Authors discuss nephrotoxicity of aminoglycosides in patients with hepatic and biliary disorders. It may be concluded that hepatic and biliary diseases should be considered as an additional gentamycin nephrotoxicity risk factor. Administration of gentamycin to such patients require dose adjustments to renal function and--if possible--to gentamycin serum level.
