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.

PURPOSE: Hyperphosphatemia and renal osteodystrophy increase the mortality and morbidity in chronic kidney disease. We compared the effects of lanthanum carbonate (LC) and calcium carbonate (CC) on phosphate homeostasis and bone bio-markers in hemodialysis patients. METHODS: The Korean dialysis patients with serum phosphorus more than 5.6 mg/dL were randomized to LC (n=12) or CC (n=11). Serum calcium, phosphorus, intact PTH, bone alkaline phosphatase, and osteocalcin were checked at regular intervals for 6 months. RESULTS: The reduction of serum phosphorus and calcium x phosphorus product at 24-week (wk) from baseline values was similar in LC and CC groups (Phosphorus: baseline, 7.28+/-1.04 mg/dL vs 7.41+/- 1.39 mg/dL, p=NS; at 24-wk, 5.39+/-1.85 mg/dL vs 5.67+/-1.43 mg/dL, p=NS) (Calcium x phosphorus product: baseline, 64.5+/-11.1 mg2/dL2 vs 61.3+/-11.9 mg2/dL2, p=NS; at 24-wk, 47.9+/-14.5 mg2/dL2 vs 51.8+/-14.0 mg2/dL2, p=NS). Despite higher baseline serum calcium levels in LC group, the changes of serum calcium from the baseline at 24-wk were significantly higher in CC group (LC vs CC; 0.23+/-0.38 mg/dL vs 0.94+/-0.87 mg/dL, p<0.05). Bone bio-markers, including iPTH, bone ALP, and osteocalcin, were comparable in 2 groups. However, significant gastrointestinal side effects leading to discontinuing the study were predominantly observed in LC (LC vs CC; n=5/12 vs n=0/11). CONCLUSION: Compared to calcium carbonate, lanthanum carbonate has similar efficacy to reduce serum phosphorus level, but less tendency to increase serum calcium level. However, the high incidence of gastrointestinal side effects in lanthanum carbonate needs further investigation in its correlation to Korean.

We report a rare case of the concurrent manifestation of central diabetes insipidus (CDI) and type 2 diabetes mellitus (DM). A 56 year-old man was diagnosed as a type 2 DM on the basis of hyperglycemia with polyuria and polydipsia at a local clinic two months ago and started an oral hypoglycemic medication, but resulted in no symptomatic improvement at all. Upon admission to the university hospital, the patient's initial fasting blood sugar level was 140 mg/dL, and he showed polydipsic and polyuric conditions more than 8 L urine/day. Despite the hyperglycemia controlled with metformin and diet, his symptoms persisted. Further investigations including water deprivation test confirmed the coexisting CDI of unknown origin, and the patient's symptoms including an intense thirst were markedly improved by desmopressin nasal spray (10 microg/day). The possibility of a common origin of CDI and type 2 DM is raised in a review of the few relevant adult cases in the literature.

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.

The osmotic demyelination syndrome (ODS) is a distinctive clinical entity with characteristic MR features in the central pons (central pontine myelinolysis, CPM) and other locations (extrapotine myelinolysis, EPM). ODS is mainly seen following rapid correction of the serum sodium level in hyponatremic patients. In the past, ODS used to be considered as fatal. However, some recent reports have described cases of survival from this syndrome, but most survivors seem to suffer irreversible neurological deficits. We report one case of 46-year-old woman who developed stupor at day 7 and the other case of 56-year-old woman with drowsiness, dysarthria and dysphagia at day 3 following the correction of hyponatremia. In both cases, the serum potassium levels were low at the time of presentation with hyponatremia. By means of brain MRI, the first case was diagnosed as CPM with EMP and the second case as isolated EPM. With conservative treatments, complete neurological recovery was achieved at 4-6 weeks after onset of ODS.
