Abstract

Background: Potassium balance is an important concern of nephrologists when treating patients on dialysis. However, the amount of potassium removed by predilution online hemodiafiltration has not been investigated in prior studies. The purpose of the study was to investigate the amount of potassium removed by predilution online hemodiafiltration compared to conventional hemodialysis. Methods: This study traced the amount of potassium removed in each session among 23 patients undergoing both conventional hemodialysis and predilution online hemodiafiltration. The effect of the concentration of potassium and bicarbonate in the dialysate was evaluated. Finally, the influence of ß-blocker use on potassium homeostasis was also assessed. Results: There was no difference in mean serum potassium levels between conventional hemodialysis and predilution online hemodiafiltration [P = NS (nonsignificant)] before and 1 hour after the end of the session (P = NS). Significantly less potassium was removed in conventional hemodialysis compared to predilution online hemodiafiltration (P < .0001). The amount of potassium removed in conventional hemodialysis was lower in the high potassium dialysate group (P < .02) and in those undergoing predilution online hemodiafiltration (P < .03). The use of ß-blockers was associated with higher predialysis serum potassium levels in the group of conventional hemodialysis. Conclusion: The present study shows that in predilution online hemodiafiltration, much more potassium is removed than in conventional hemodialysis. Potassium removal is greater with low potassium dialysate in both methods. The use of ß-blockers is associated with higher predialysis serum potassium levels in conventional hemodialysis, while dialysate bicarbonate concentration does not substantially affect the amount of potassium removed during dialysis.

Abstract

Respiratory alkalosis during hemodialysis session is a rare complication. We managed two patients with severe respiratory alkalosis, a woman who developed this 75 min after the beginning of the session and a man who developed it about 1 h before the end of the session. In both, the cause was a hypotensive episode, and both hypotension and alkalosis were successfully treated. [ABSTRACT FROM AUTHOR]

Abstract

Background: Ensuring vascular access is essential for dialysis patients. This can be achieved through an arteriovenous anastomosis (fistulae), a central venous catheter, or an arteriovenous graft. However, in some cases vascular access to the patient's blood is not possible. Case Presentation: A multi-vascular male patient, who had been undergoing dialysis for 17 years, was presented to our renal department. There was no possibility of vascular access to the patient's venous network for dialysis. A peritoneal dialysis catheter was inserted, but it was malfunctioning. An attempt was made to place a HeRO AV Graft, but it did not succeed due to contraindications from the patient's venous network, as shown by the computed tomography. While trying to solve the problem in order to dialyze the patient during his hospitalization, he experienced severe shortness of breath with tachypnea (pulmonary edema), along with acidosis and hyperkalemia. A temporal dialysis catheter was urgently inserted into the left femoral artery and isolated ultrafiltration was performed, and by removing 1500 ml of ultrafiltration, the patient improved significantly. During the subsequent days, he underwent another 11 dialysis sessions using the femoral artery catheter. While he was hospitalized and being dialyzed via the femoral artery, a successful effort was made to catheterize the right external jugular vein, from which he continues to be dialyzed today. Conclusion: The patient's treatment through the placement of a temporal dialysis catheter in the femoral artery enabled him to survive. It is our belief that such a solution could be helpful in similar cases. [ABSTRACT FROM AUTHOR]

Abstract

A 67-year-old diabetic and hypertensive woman presented to us with very low serum phosphate levels (PO4 - =1.1 mg/dL) about 40 days after initiation of hemodialysis (HD). The phosphate binders were discontinued, because they were thought to be the cause of hypo-phosphatemia. However, the serum phosphate levels continued to remain low during subsequent follow-up visits over one month (PO4 --- = 0.7 and 0.6 mg/dL respectively). The patient had been started on metformin hydrochloride (850 mg thrice a day) about 18 days after the beginning of HD. The drug was stopped immediately (approximately 50 days after it was started) and the serum phosphate levels increased progressively, reaching 4.3 mg/dL. During the period with hypophos-phatemia, the patient suffered from very intense fatigue and weakness (she was unable to walk), anorexia, diarrhea and tenesmus. There were no features suggestive of rhabdomyolysis, hemo-lysis, low blood pressure or hypoglycemia; she had low white blood cell and platelet counts. The patient was in good clinical condition 2-3 days after the discontinuation of metformin and she recovered totally 15 days later. This case is presented due to its rarity as well as the observation that despite the patient having severe hypophosphatemia, she showed only side effects of metformin. Hypophosphatemia caused only intense fatigue and no other symptoms.

Abstract

Anemia is a serious problem in hemodialysis patients, the main cause of which is erythropoietin deficiency. After the discovery of recombinant human erythropoietin (rHuEpo) at the end of the last decade, the hematological profile of hemodialysis patients improved significantly but at considerable expense. The deformability of red blood cells (RBC) influences their microcirculation and tissue oxygen delivery along with their life span. We investigated the deformabilty of RBCs in 15 hemodialysis patients before and after three months on L-carnitine supplementation (30 mg/Kg body wt/dialysis session). We excluded from the study all patients who received blood transfusions three months before or during the study, patients who had hemorrhagic episodes, those with hyperparathyroidism or infections, and any who required surgical intervention during the study. The serum iron, folic acid and vitamin B-12 levels were kept normal during the duration of the study. The erythropoietin dose taken before the beginning of L-cartnitine supplementation was not changed. The deformability of RBCs before and after dialysis, prior to and following three months on L-carnitine was determined and compared to the deformability of RBCs from a control group. Hematocrit levels were measured before entry into the study and every month for three months. We found that the deformability of RBCs before the dialysis session was significantly greater than that found in the control group (t-test, p < 0.00001), and that there was a further increase after the end of the dialysis session. Three months following L-carnitine supplementation, we found a significant reduction of RBCs deformability (paired t-test, p < 0.004), and a significant increase in the hematocrit (ANOVA, p < 0.0001). We concluded that abnormalities in the deformability of RBCs improved after L-carnitine and that this was responsible for the increase in the hematocrit. This may allow a substantial reduction in rHuEpo dose.

Abstract

The influence of l-carnitine supplementation on hematocrit (Hct) and hemoglobin (Hb) levels, in patients suffering from end stage renal disease (ESRD) on maintenance hemodialysis, are well known from several studies. The data concerning the serum levels of carnitine, in patients with ESRD on continuous ambulatory peritoneal dialysis (CAPD) are contradictory, but most of them support that they are rather normal. In this study the effect of l-carnitine supplementation on Hct, and Hb levels were investigated in patients suffering from ESRD on CAPD. In the study 12 patients were included (5 F, 7 M), aged from 39 to 92 years old (median 65.5 years), who were on CAPD for more than 6 months (from 6 to 15 months, mean ± SD = 8.6 ± 3.6), with normal serum ferrum and ferritin levels at the beginning of the study. Two grams of l-carnitine/day per os (Superamin, Vianex Hellas), were administered in all the patients and the serum ferrum levels were tried to be kept stable, by exogenous ferrum administration, during the study period. If the Hct levels were more than 36% per month the erythropoietin (rHuEpo) dose of the patient was decreased monthly at the half dose/week. The changes of Hct, Hb, ferrum and ferritin levels, as well as the Indice de Rigidite (IR) of the erythrocytes were recorded, before and after the first, second and third month of the study period. Finally, the rHuEpo dose/patient was registered monthly before and during the study. During the observations, Hct (35.4 ± 3.3 vs. 38.1 ± 3.4, ANOVA, p < 0.03) and Hb levels (11.0 ± 1.1 vs. 11.9 ± 1, ANOVA, p < 0.01), were significantly increased. On the other hand, rHuEpo dose necessity/patient/week was decreased significantly (3833 ± 3326 vs. 1292 ± 1712, ANOVA, p < 0.01), in order to succeed the target Hct level. Furthermore, red blood cells IR also appeared to have a significant decrease (16.6 ± 7.4 vs. 13.0 ± 3.9, paired t-test, p < 0.03). Finally, the ferrum... [ABSTRACT FROM AUTHOR]
