[GBV-C/HGV, a new virus as one possible cause of hepatitis of unknown etiology].

For etiologically obscure (some 4%) viral hepatitis agents are sought and tested to make elucidation of their cause possible. One of the candidates is since 1995 the newly discovered virus GBV-C/HGV. Despite intense research its relationship to viral hepatitis of obscure origin (VHN) has not been elucidated so far.

[Evaluation of the adequacy of hemodialysis from the aspect of urea kinetics models].

Background: One of the widely used indicators of adequacy of haemodialysis (HD) is assessment of the Kt/V of urea (K-dialysis clearance of urea, t-time of haemodialysis, V-distribution volume of urea). Work accomplished in recent years suggests that when the HD is adequate, the value of Kt/V should be 1.5.

[Kinetics of phosphorus in individuals on regular dialysis therapy].

In eight subjects with hyperphosphataemia included in regular dialyzation treatment repeatedly phosphorus kinetics (iP) were assessed based on changes in serum concentrations and the amount of iP removed from the organism during every dialysis (D). The serum concentration of iP before dialysis (HD) was on average 3.06 (+/- 0.

[A nutritionally defined liquid diet for hemodialyzed patients].

Background: For patients having regular haemodialysis there are no suitable complete preparations for general use in case intensive treatment is needed. Nutrilac renal is a new preparation of a nutritionally defined liquid diet corresponding as to its composition to the needs of haemodialyzed patients. The purpose of the present work was to assess whether this preparation when administered as a supplement will have a favourable effect on the nutritional parameters of haemodialyzed patients.
