Background: Sodium sensitivity (SS) and insulin resistance (IR) might be a common link in the pathogenesis of essential hypertension. The aim of the present study is to investigate the relationship, if any, between SS and IR in a population with a family predisposition to develop hypertension.
Methods: Twenty normotensive subjects aged 20 to 40 years with a family history of hypertension (1 or both parents hypertensive) and no other risk factor (group A) and 10 normotensive subjects aged 20 to 40 years without a family history of hypertension (group B) were enrolled.
The counts of yeasts and filamentous fungi were investigated in the municipal water supplies of haemodialysis centres, in the treated water and the dialysate from all 85 haemodialysis units in Greece, in order to estimate their occurrence, their correlation with contamination indicator bacteria and other influencing factors. Filamentous fungi and yeasts were isolated from 69 (81.2%) and from three (3.

Considering the conflicting data of few existing studies, we examined the influence of erythropoietin (EPO) treatment on insulin resistance and tested the probable correlation of this influence with sympathetic nervous system (SNS) activity.
Methods: We studied 8 non-obese, non-diabetic, stable dialysis patients using the euglycaemic insulin clamp technique before administration of EPO (phase A), 10 days after (phase B), and after the correction of the haematocrit level, at least 8 weeks later (phase C).
