Acid Base Status

Abstract Introduction: It is unclear whether residual renal function (RRF) in dialysis patients can attenuate the metabolic impact of the long 68-hour interdialytic interval, in which water, acid, and electrolyte accumulation occurs. Objective: to evaluate serum electrolyte levels, water balance, and acid-base status in dialytic patients with and without RRF over the long interdialytic interval (LII). Methodology: this was a single-center, cross-sectional, and analytical study that compared patients with and without RRF, defined by diuresis above 200 mL in 24 hours. Patients were weighed and serum samples were collected for biochemical and gasometric analysis at the beginning and at the end of the LII. Results: 27 and 24 patients with and without RRF were evaluated, respectively. Patients without RRF had a higher increase in serum potassium during the LII (2.67 x 1.14 mEq/L, p < 0.001), reaching higher values at the end of the study (6.8 x 5.72 mEq/L, p < 0.001) and lower pH value at the beginning of the interval (7.40 x 7.43, p = 0.018). More patients with serum bicarbonate < 18 mEq/L (50 x 14.8%, p = 0.007) and mixed acid-base disorder (57.7 x 29.2%, p = 0.042), as well as greater interdialytic weight gain (14.67 x 8.87 mL/kg/h, p < 0.001) and lower natremia (137 x 139 mEq/L, p = 0.02) at the end of the interval. Calcemia and phosphatemia were not different between the groups. Conclusion: Patients with RRF had better control of serum potassium, sodium, acid-base status, and volemia throughout the LII.

Calcium Loss

The original contributions of Jacob Lemann to mineral metabolism, especially calcium metabolism and idopathic hypercalciuria, are reviewed. One group of studies concern acid base balance and calcium loss, showing that acid loads increase calcium loss in the urine. Another group of studies concern the calciuria of glucose or carbohydrate ingestion, with the observation that stone patients, who as a population are enriched with hypercalciuria, respond with more exaggerated calciuria to glucose loads than do normal people. Yet another body of work shows that normal men, when given noncalcemic loads of calcitriol, exhibit two essential features of idiopathic hypercalciuria--hyperabsorptive hypercalciuria and bone mineral loss on a low-calcium diet. The final group of studies presented worked on the problem of thiazide hypocalciuric action, and where the calcium goes that does not appear in the urine, as well as the effects of potassium bicarbonate and sodium loads on mineral balance and acid base status.

Friesian Cows

The objective of this study was to determine the effect of an anionic diet on mineral metabolism, acid-base status and udder oedema of dairy cows fed grass silage based diets during the dry period. Eighteen pregnant, non-lactating Friesian cows were divided randomly into two groups according to their expected calving date. Dietary cation-anion balance (DCAB), calculated as mill equivalents [(Na + + K + ) - (Cl - + S 2- )], for high DCAB (control) and low DCAB treatments were +254 and -41 mEq kg -1 dry matter (DM), respectively. Anionic salts were ammonium chloride (NH 4 Cl), magnesium chloride (MgCl 2 ) and magnesium sulphate (MgSO 4 ). Cows received grass silage (5.2 kg DM), hay (0.9 kg DM) and a concentrate mixture (2.7 kg DM) until calving. Blood and urine samples were collected 4, 3, 2 and 1 week before the expected calving date, at calving, 1 day and 1 week after calving. Udder oedema was evaluated by a quantitative and a subjective method. Acidification resulted in a marked decrease in urinary pH, increased urinary Ca excretion and a change in blood acidbase balance. Blood Ca 2+ and plasma Ca tot concentrations were more stable at parturition for the anionic group, although such differences were not statistically significant. Anionic salts (DCAB -41 mEq kg -1 DM) did not cause udder oedema in experimental cows.;
