This review article is intended to show and understand psychosocial factors in patients with chronic kidney disease (CKD) including end-stage renal disease (ESRD) on renal replacement therapy. These patients suffered from many psychosocial factors such as depression, sleep disorder, and chronic pain, etc. The prevalence of major depression or a defined psychiatric illness in ESRD patients is not clearly defined, but is roughly estimated between 5% and 50%. Unfortunately many sufferers do not seek treatment, and of those who do, significant numbers are improperly diagnosed or are not appropriately treated. They should be managed by psychiatric medication and interview, because depression could affect medical outcomes in ESRD patients through several mechanisms. Sleep disorders are common in ESRD patients treated with dialysis and are associated with patients' perceptions of quality of life, assessed by diverse measures, as well as depressive mood. Although pain has been considered as a problem for ESRD patients for more than 20 years, few studies exist on this subject. Pain appears to be an undervalued problem for ESRD patients. These psychosocial factors could affect morbidity, mortality and life quality in CKD and ESRD patients. The physicians, especially managing CKD patients, need to consider these factors.

This study aimed to assess the effects of different dialysate bicarbonate concentrations in correcting acid-base imbalance in 53 stable hemodialysis patients in a university-hemodialysis unit. Three different bicarbonate concentrations were assigned, i.e. 25 mEq/L in 10, 30 mEq/L in 30, and 35 mEq/L in 13 patients. Blood gas analyses from arterial line blood samples before and after dialysis in the mid-week were performed for the determination of pH and serum bicarbonate concentration ([HCO3-]). The mean values of predialysis arterial [HCO3-] were mildly acidotic in all 3 groups, but not significantly different among them, whereas those of post-dialysis arterial [HCO3-] were alkalotic, especially in the group of 35 mEq/L as compared with the other two groups. The mean blood pH was not significantly different among the 3 groups. As expected, there was a positive correlation between pre-dialysis pH and post-dialysis pH (r=0.45, p=0.001), and pre-dialysis [HCO3-] and post-dialysis [HCO3-] (r=0.58, p=0.000), but with a negative correlation between pre-dialysis [HCO3-] and the increment of intradialytic [HCO3-] following hemodialysis (r=-0.46, p=0.001). In conclusion, this study shows that the impact of conventional dialysate bicarbonate concentrations ranging from 25 to 35 mEq/L is not quite different on the mild degree of predialysis acidemia, but the degree of postdialysis alkalemia is more prominent in higher bicarbonate concentrations. Base supply by hemodialysis alone does not seem to be the main factor to determine the predialysis acidosis in end-stage renal disease patients on chronic maintenance hemodialysis.

On view of the absent or minimal osmotic diuresis in end stage renal disease, hyperglycemia on maintenance hemolysis as compared to nonketotic hyperosmolar status without underlying advanced renal failure has been noted to show a wide clinical spectrum form severe manifestations by hypertonicity to no clinical manifestations at all. We experienced a 60-year-old man with a known history of type 2 diabetes mellitus on maintenance hemodialysis for 2 years, who was admitted 4 times within 1 year with hyperglycemia (>500 mg/dL) accompanied by recurrent nausea and vomiting at each admission. However, the calculated effective osmolality (tonicity) in this case ranged only from 286 to 303 mOsm/kg H2O. During the past 6 months following meticulous education for the importance of compliance to medication, especially prokinetics for diabetic gastroparesis, he developed no further episode of hyperglycemia or nausea and vomiting.

This study aimed to compare the increment in plasma potassium concentration ([K+]) as well as the role of internal K+ balance for its changes following acute K+ supplementation between conventional 2.5% glucose (GD) and non-glucose containing dialysate (icodextrin, ID) in continuous ambulatory peritoneal dialysis (CAPD) patients. A total of 9 stable CAPD patients (5 men and 4 women; age, 56+/-13 years; 7 type-2 diabetics and 2 non-diabetics) on daily 4 exchanges of 2 L of glucose dialysate underwent the 6-hr dwell on fasting in the morning with 2 L of 2.5% glucose mixed with 20 mEq/L of KCl, and then the same regimen was repeated with icodextrin after 1-wk interval. The degree of intraperitoneal absorption was comparable, 65+/-2% in GD and 68+/-2% in ID, respectively (p=NS). However, despite the similar plasma K+ levels at the baseline of both regimens, its increment was significantly less in GD than ID, which was accompanied by more marked increase in the calculated intracellular K+ redistribution (68+/-3% vs. 52+/-3%, p<0.05). The basal levels of insulin were similar between the GD and ID groups. However, the change, checked up after 2 hours' dwell, from the basal insulin levels was much lower on ID. ID with a lesser degree of transcelluar K+ shift by the decreased secretion of insulin is more effective than the conventional glucose solution for acute K+ repletion via dialysate during CAPD. Furthermore, these results suggested that the role of insulin for the internal K+ balance was intact even in type-2 diabetic patients on CAPD

Although renal calcium crystal deposits (nephrocalcinosis) may occur in acute phosphate poisoning as well as type 1 renal tubular acidosis (RTA), hyperphosphatemic hypocalcemia is common in the former while normocalcemic hypokalemia is typical in the latter. Here, as a unique coexistence of these two seperated clinical entities, we report a 30-yr-old woman presenting with carpal spasm related to hypocalcemia (ionized calcium of 1.90 mM/L) due to acute phosphate poisoning after oral sodium phosphate bowel preparation, which resolved rapidly after calcium gluconate intravenously. Subsequently, type 1 RTA due to Sjogren's syndrome was unveiled by sustained hypokalemia (3.3 to 3.4 mEq/L), persistent alkaline urine pH (> 6.0) despite metabolic acidosis, and medullary nephrocalcinosis. Through this case report, the differential points of nephrocalcinosis and electrolyte imbalances between them are discussed, and focused more on diagnostic tests and managements of type 1 RTA.

Ultrasound-guided cannulation of a large-bore catheter into the internal jugular vein was performed to provide temporary hemodialysis vascular access for uremia in a 65-yr-old woman with acute renal failure and sepsis superimposed on chronic renal failure. Despite the absence of any clinical evidence such as bleeding or hematoma during the procedure, a chest x-ray and computed tomographic angiogram of the neck showed that the catheter had inadvertently been inserted into the subclavian artery. Without immediately removing the catheter and applying manual external compression, the arterial misplacement of the hemodialysis catheter was successfully managed by open surgical repair. The present case suggests that attention needs to be paid to preventing iatrogenic arterial cannulation during central vein catheterization with a large-bore catheter and to the management of its potentially devastating complications, since central vein catheterization is frequently performed by nephrologists as a common clinical procedure to provide temporary hemodialysis vascular access.

Hyperkalemic paralysis can be either a rare hereditary form due to channelopathies or common secondary ones related to various medications interfering potassium homeostasis upon underlying renal impairment. We hereby describe a 36-yr-old woman presented with the first episode of sudden hyperkalemic paralysis due to severe hyperkalemia, 8.6 mEq/L, but which resolved quickly to the normalization of serum potassium level by the conventional remedies, including calcium gluconate, insulin and glucose, and potassium-binding resin for severe hyperkalemia over 10 hours and remained normokalemic without any medications or dialysis for the next 10 days in hospital. The discernible history of medications or potassium-rich food intakes was denied on repeated interrogation. Other diagnostic work-ups to investigate its etiologies responsible for this acute hyperkalemic paralysis including neurological examination, serial biochemical data, and endocrinologic diagnostic work-ups for underlying causes failed, but only revealed only a transient hyperkalemic episode with appropriate response of renal potassium excretion. Therefore, we report a puzzling case of hyperkalemia with unexplained causes in a young woman, though the evidences are in favor of acute intracellular potassium shift based on the short duration of reversible hyperkalemia with intact response of increased renal potassium excretion.
