More on the increase of hemoglobin A1 in chronic renal failure: the role of acidosis.

In chronic renal failure both Hb A1 and Hb A1c levels have been reported to be elevated. In order to investigate the causes of such increase we measured Hb A1 (cation-exchange chromatography), blood urea nitrogen, arterial blood pH and plasma bicarbonate in 40 patients with chronic renal failure receiving conservative treatment, 45 uremic patients on intermittent hemodialysis and 60 subjects with normal renal function. In patients with chronic renal failure Hb A1 highly correlates with arterial blood pH and plasma bicarbonate, thus emphasizing the major role played by uremic acidosis in the increased Hb A1 fraction in chronic renal failure.

Origin of glycosylated hemoglobin A1 in chronic renal failure.

In chronic renal failure both HbA1 and HbA1c levels have been reported to be elevated. In order to investigate the causes of such increase we measured HbA1 (cation-exchange chromatography), blood urea nitrogen, arterial blood pH, plasma bicarbonate, phosphatemia, serum iron and serum ferritin before dialysis in 60 uremic patients receiving long term hemodialysis. The increased levels of HbA1 do not correlate with glucose intolerance, phosphatemia, blood urea nitrogen, time averaged concentration of urea, serum iron and serum ferritin. On the contrary the presence of a highly significant correlation between HbA1 and arterial blood pH (p less than 0.001) and between HbA1 and plasma bicarbonate (p less than 0.001) seems to emphasize a major role for acidosis in increasing the HbA1 levels in uremic patients on long term hemodialysis.

[Central vascular access: rational and results].

Central venous catheterization for hemodialysis using double cannula has become the preferred central vascular form in acute cases. Moreover, in chronic cases, this form of vascular access has replaced the internal arterio-venous fistula whenever the latter is difficult to realize, or when patient's cardio-circulatory condition would discourage its creation. The central vascular access presents frequent complications, compromising their efficiency and duration. Tesio's central venous catheters were thoroughly studied and manufactured to overcome these complications, allowing a long life span of the vascular access. In this study 108 patients with Tesio's internal jugular central venous catheters were followed-up in the period 1990 to 1994. All patients underwent hemodialysis in Pordenone Center. Central venous access survival fluctuated between 93% and 82% in the first year and the fifth year respectively. However, access survival dropped to 32% after seven years. The accurate choice of the catheters' manufacturing material as well as the correct technical positioning has determined a significant increase in the vascular access survival, thanks to the important decrease in prevalence and seriousness of complications. We believe that the decreased accuracy in catheter management over time is the major cause of delayed loss of the central vascular access.
