ABSTRACT
BACKGROUND: Cicletanine is an antihypertensive agent with vasorelaxant and diuretic properties. It has been widely used in European countries; however, cicletanine-associated electrolyte disturbances have yet to be defined. We investigated cicletanine-induced hyponatremia and hypokalemia in kidney transplant patients. METHODS: Data from a total of 68 kidney transplant recipients who were treated for hypertension with cicletanine were retrospectively analyzed. Cicletanine-induced hyponatremia and hypokalemia were defined as serum sodium < 135 mmol/L and potassium < 3.5 mmol/L, respectively, after the use of cicletanine. RESULTS: The average patient age was 50 (±11) years, and 44 (65%) were male. The daily dose of cicletanine was 171 ± 46 mg, and the duration of drug use was 215 ± 514 days. Hyponatremia occurred in 11 patients (16.2%), and hypokalemia occurred in 8 patients (11.8%). Three patients (4.4%) had hyponatremia and hypokalemia simultaneously. The duration of cicletanine administration was significantly longer in patients with hyponatremia than in those without hyponatremia (943 ± 958 vs. 74 ± 166 days, P < 0.05). The occurrence of hypokalemia was not affected by either daily dose or duration of drug use. Among 11 patients with hyponatremia, 10 were corrected within 2 weeks after withdrawal of the drug and 1 was spontaneously corrected. Among 8 cases of hypokalemia, 7 were corrected after withdrawal of the drug and 1 was spontaneously corrected. CONCLUSION: We demonstrate that cicletanine may induce hyponatremia or hypokalemia in kidney transplant patients. Hyponatremia is more frequently associated with cicletanine than hypokalemia, and extended use of cicletanine may increase the risk of hyponatremia.

Cryptococcosis commonly affects patients with immune dysfunction, as in the case of immunosuppression in organ transplant patients or as acquired immunodeficiency syndrome in patients afflicted with human immunodeficiency virus. The varied appearance of cryptococcal skin lesion makes clinical diagnosis of cutaneous cryptococcosis difficult. Cryptococcosis proves to be a fatal fungal infection in the immunocompromised patient. Therefore, diagnosis and early treatment of cryptococcosis become vital. A 56-year-old renal transplant recipient, with an ongoing immunosuppression regimen of cyclosporine, prednisolone, and mycophenolate mofetil, was admitted with a 2-week history of pain and edema of right arm without respiratory symptoms. Despite empiric antibiotic therapy, the patient continued to complain of severe tenderness of the involved arm and fever persisted as well. On the third day of hospital stay, a biopsy of the erythematous skin lesion was acquired. On the eighth day of hospital stay, results of both skin biopsy and blood cultures showed the presence of Cryptococcus neoformans. The treatment was begun with intravenous fluconazole (400 mg/day). After 4 days of antifungal treatment, the patient developed fever along with cough with purulent sputum. As the new developing symptoms were suggestive of pneumonia, especially of pulmonary cryptococcosis, the antifungal agent was changed from fluconazole to amphotericin B treatment (0.8 mg/kg, 50 mg/day). Chest computer tomography showed improvement in the pneumonic infiltration and consolidation after 4 weeks of amphotericin B treatment. In conclusion, cellulitis in immunocompromised patients should be suspected in case of highly atypical infectious etiology, and skin biopsy should not be delayed if empiric antibiotic therapy does not control the inflammatory response. Additionally, the patient should be treated with intravenous amphotericin B treatment in case of severe cryptococcosis.

BACKGROUND: Because hemodiafiltration (HDF) involves large amounts of ultra-filtration and substitution fluid infusion, its effects on serum electrolytes may be different from those of hemodialysis (HD). Serum sodium and blood pressures were compared between patients undergoing online HDF and high-flux HD (HFHD). METHODS: Thirty-two of 101 patients on HFHD switched voluntarily to online HDF. Their pre- and postdialysis serum measurements were compared with those of the remaining 69 HFHD patients. RESULTS: Online HDF patients had lower pre- and postdialysis systolic blood pressures (SBPs) than HFHD patients (predialysis, 136+/-21 vs. 145+/-19 mmHg, P<0.05; postdialysis, 129+/-22 vs. 142+/-25 mmHg, P<0.05). Pre- and postdialysis serum sodium concentrations were not significantly different between online HDF and HFHD (predialysis, 138+/-2 vs. 137+/-3 mEq/L; postdialysis, 134+/-2 vs. 134+/-2mEq/L). However, the change in serum sodium concentration after dialysis was greater in online HDF than HFHD patients (-3.7+/-2.2 vs. -2.5+/-2.8 mEq/L, P<0.05). The change in serum sodium concentrationwas correlated with postdialysis SBP (r=0.304, P<0.005) and pulse pressure (r=0.299, P<0.005). Predialysis SBP (r=0.317, P<0.005) and pulse pressure (r=0.324, P=0.001) were also correlated with the postdialysis serum sodium change. CONCLUSION: Compared with HFHD, online HDF has a greater serum sodium lowering effect. This might contribute to the ability of online HDF to stabilize both pre- and postdialysis SBP.

Ischemic steal syndrome (ISS) is one of the serious complications that can occur after construction of an arteriovenous fistula (AVF) for hemodialysis (HD). Because AVF-related ISS symptoms are usually aggravated during HD sessions, a few cases of ISS in kidney transplantation (KT) recipients have been reported in the literature. We describe a 63-year-old male with diabetic nephropathy who created AVF for maintenance HD and presented with pain at rest and tissue necrosis of the left distal fingers at 10 years post-KT. Brachial angiography revealed the presence of attenuated blood flow through the distal ulnar artery. He underwent finger amputation and AVF ligation, leading to complete relief of ischemic symptoms. The aim of this case report is to help clinicians to diagnosis a steal syndrome in kidney transplantation with a careless AVF for a long period of time.

The first Medical Terminology was published by the Korean Medical Association in 1977 in Korea. Since then 4 more editions of Medical Terminology have been published. The final one, the 5th edition was published in 2009. Among these, in the 3rd edition, almost all of the medical terms were words in Chinese characters. In contrast, the 4th edition had been completely changed. Almost all of the terms were Hangul (Korean language) terms. The 5th edition accepted both terms in Chinese characters and Hangul terms. Owing to this major shift in medical terminology, users of medical terms have been greatly inconvenienced. At present, the Medical Terminology Committee of the Korean Medical Association are carrying out the work of selecting the representative term for each medical term. Medical terms should be easily understandable because medical terms are used by lay people as well as medical doctors. For easy and efficient communication between the doctor and the patient, it is not important whether the term is in Chinese characters or Hangul terms. The work of selecting representative terms should be carried out in rational way. Close communication and cooperation between the Medical Terminology Committee of the Korean Medical Association and each academic medical society in the Republic of Korea is necessary for consistency in establishing medical terminology. A system for collection and translation of medical terms newly coined and imported from abroad should be developed.

BACKGROUND: The impact on quality of life (QOL) and safety has increasingly been an important consideration for living donors after kidney transplantation. The purposes of this study were to evaluate the QOL of living kidney donors and to indentify factors for impediment of their QOL. METHODS: The subjects of this study were 69 living kidney donors with whom transplantations were performed in our center from 1990 to 2010. The data was collected from May to July 2010 using donor characteristics and SF-36. RESULTS: The donors were predominantly female (60.9%) and the average age was 45.4+/-12.0 years. The total numbers of donors, categorized by their relationship to the recipients, included 20 siblings (29.0%), 17 parents (24.6%) and 13 spouses (18.8%). The measured characteristics as related to donation included the full return to normal pre-donation activities (72.5%), no visit to a hospital or pharmacy after donation (69.6%) and donation decision as propria persona (97.1%). Most donors were satisfied with their donation (92.8%) and had no regrets for making the donation (87.0%). The average score for QOL of all subjects was 71.89. The overall QOL of living kidney donors revealed lower scores (48.56+/-5.45) as compared to average scores (50) of the healthy population in the USA. In particular, the scores for PCS (52.87) on the SF-36 were higher than the scores for MCS (44.25). CONCLUSIONS: Most living kidney donors were satisfied with their donation and showed good physical recoveries despite a lower QOL. Consequently, carefully pre-transplantation psychological assessment and programs are necessary to support donors. Systematic and continuous management after transplantation, as well as preoperatively appropriate information and counsel, is needed for kidney donors.

BACKGROUND/AIMS: The value of hydration with sodium bicarbonate and N-acetylcysteine (NAC) in the prevention of radiocontrast-induced nephropathy is questionable. This study investigated whether sodium bicarbonate hydration with or without NAC has a more protective role in the prevention of radiocontrast-induced nephropathy than saline hydration with or without NAC. METHODS: We prospectively studied 100 patients with significant proteinuria (> or = 500 mg/d), azotemia (serum creatinine > or = 1.5 mg/dL), or diabetes mellitus who were undergoing coronary angiography using iodixanol, a nonionic iso-osmolar contrast agent. Patients were assigned randomly to receive saline infusion (S, n = 24), saline infusion plus NAC (S + NAC, n = 20), sodium bicarbonate infusion (B, n = 25), and sodium bicarbonate plus NAC (B + NAC, n = 31). Contrast-induced nephropathy was defined as an increase of 25% or more in the serum creatinine within 48 hours of contrast exposure. RESULTS: There were no significant group differences in age, sex, and basal serum creatinine. Contrast-induced nephropathy occurred in 20 patients (20%) and its incidence was not significantly different among the groups; four from group S, five from group S + NAC, five from group B, and six from group B + NAC. The incidences were not significantly different when compared between S and B, irrespective of the use of NAC (21 vs. 20%), and when compared according to the presence of pre-existing azotemia (19 vs. 20%). CONCLUSIONS: The efficacy of sodium bicarbonate hydration in the prevention of contrast-induced nephropathy seems comparable to that of saline hydration, and it was not improved by the addition of NAC.

BACKGROUND/AIMS: Short hemofilter survival and anticoagulation-related life-threatening complications are major problems in systemic anticoagulation with heparin (SAH) for continuous renal replacement therapy (CRRT). The present study examined if regional anticoagulation with citrate (RAC) using commercially available solutions can overcome the associated problems of SAH to produce economical benefits. METHODS: Forty-six patients were assigned to receive SAH or RAC. We assessed the coagulation state, clinical outcomes, and adverse events. A Kaplan-Meier analysis was used to estimate hemofilter life span. The economical benefit related to the prolonged hemofilter survival was examined on the basis of the average daily cost. RESULTS: The mean age of patients was 66.5 +/- 13.8 years and the majority were male (60.9%). While elective discontinuation was most common cause of early CRRT interruption in the RAC group (34.3%, p < 0.01), hemofilter clotting was most prevalent in the SAH group (82.2%, p < 0.01). The patient metabolic and electrolyte control and survival rate were not different between the two groups. When compared with the RAC group, the anticoagulation-associated bleeding was a major complication in the SAH group (15.0% vs. 61.5%, p < 0.01). Regional anticoagulated hemofilters displayed a significantly longer survival time than systemic anticoagulated hemofilters (59.5 +/- 3.8 hr vs. 15.6 +/- 1.3 hr, p < 0.01). Accordingly, the mean daily continuous venovenous hemodiafiltration costs in the RAC and SAH groups were $575 +/- 268 and $1,209 +/- 517, respectively (p < 0.01). CONCLUSIONS: RAC prolonged hemofilter survival, displaying an economical benefit without severe adverse effects. The present study therefore demonstrates that RAC, using commercially available solutions, may be advantageous over SAH as a cost-effective treatment in CRRT.

PURPOSE: This study was undertaken to examine whether differences exist in the hemoglobin variability according to the types of erythropoiesis stimulating agent (ESA) in hemodialysis (HD) patients. METHODS: Clinical data were retrospectively analyzed from 72 patients on maintenance hemodialysis who were using darbepoetin alfa (n=27), epoetin beta (n=27), and epoetin alpha (n=18). As parameters of hemoglobin variability, hemoglobin cycling, the variance of hemoglobin and the SD/mean of hemoglobin were analyzed. Hemoglobin cycling was defined as the presence of cycles with an amplitude >1.5 g/dL and lasting more than 2 months. RESULTS: Hemoglobin cycling was present in 53 (73.6%) out of 72 HD patients. Hemoglobin cycling in patients receiving darbepoetin alfa had greater frequency (1.63+/-0.93 vs. 1.00+/-0.88 times/year, p<0.05), amplitude (2.88+/-1.48 vs. 1.88+/-1.60 g/dL, p<0.05), and velocity (1.21+/-0.74 vs. 0.73+/-0.66 g/dL/month, p<0.05) than that in patients receiving epoetin beta. The variance of hemoglobin in patients receiving epoetin beta (0.79+/-0.53 g/dL) was smaller than that in patients receiving darbepoetin alfa (1.29+/-0.70 g/dL, p<0.05) and epoetin alfa (1.08+/-0.52 g/dL, p<0.05). Also, the ratio of SD/mean of hemoglobin in patients receiving epoetin beta (8.20+/-2.59%) was lower than that in patients receiving darbepoetin alfa (10.81+/-2.10%, p<0.05) and epoetin alfa (10.30+/-2.10%, p<0.05). CONCLUSION: Hemoglobin variability is differential according to various ESAs, and it may be less with epoetin beta compared with darbepoetin alpha and epoetin alpha.

BACKGROUND/AIMS: Whereas higher dialysate calcium (Ca) levels may pose a risk of hypercalcemia, lower levels may induce a negative Ca balance. We evaluated the effect of lowering dialysate Ca levels from 1.75 to 1.5 mmol/L and explored the appropriate use of calcitriol to regulate bone metabolism in hemodialysis patients. METHODS: The dialysate Ca levels of 36 patients were reduced from 1.75 to 1.5 mmol/L. They were divided into three groups according to basal intact parathyroid hormone (iPTH) level (group 1, iPTH 300 pg/mL, n = 8). Data were collected at 3-month intervals for 1 year. RESULTS: Throughout the study period, no significant difference in phosphate binders, serum Ca, phosphorus (P), or Ca x P products was observed among groups. However, iPTH, alkaline phosphatase (AP), and calcitriol dosage patterns differed among groups. In group 1, iPTH and AP increased significantly over 12 months (p = 0.01). In group 2, iPTH and AP showed no significant changes. In group 3, iPTH and AP declined significantly over 12 months (p = 0.02). Calcitriol dosage did not change in groups 1 and 2, but increased significantly in group 3 (p = 0.001). CONCLUSIONS: After converting hemodialysate Ca levels from 1.75 to 1.5 mmol/L, the initially different iPTH concentrations converged to a modestly elevated level. The use of 1.5 mmol/L hemodialysate Ca may thus be appropriate for both high- and low-turnover bone disease if phosphate binders and calcitriol are combined appropriately.

BACKGROUND/AIMS: This study characterized the cisplatin nephrotoxicity occurring in patients treated with chemotherapy for lung cancer. METHODS: In all, 124 patients with lung cancer received cisplatin 70 mg/m2 on day 1 every three weeks for up to six cycles with preventive hydration using 3 L of 0.45% saline. Acute and chronic cisplatin nephropathy were defined as an increase in serum creatinine > or =30% at 3 weeks after each cisplatin administration and an increase in serum creatinine > or = 50% after the six cycles of chemotherapy, respectively. RESULTS: Acute cisplatin nephropathy occurred in 23 of 124, 8 of 110, 6 of 92, 10 of 68, 7 of 59, and 7 of 45 patients after the 1st to 6th cycle of chemotherapy, respectively. In all, 51 patients (51.5%) experienced acute cisplatin nephropathy. Chronic cisplatin nephropathy occurred in 25 out of 45 patients (55.5%). The occurrence of chronic cisplatin nephropathy was significantly associated with that of acute cisplatin nephropathy (p<0.01). In chronic cisplatin nephropathy, the serum creatinine increased to 1.82+/-1.18 mg/dL from the basal 0.82+/-0.11 mg/dL (p<0.01). It was 1.60+/-1.05 mg/dL at the end of the follow-up period (112+/-90 days). CONCLUSIONS: Despite prophylactic hydration, the incidence of cisplatin nephropathy in patients with lung cancer is still high. Acute cisplatin nephropathy may predispose patients to chronic cisplatin nephropathy, but the latter does not seem to be progressive.

Although coagulase-negative staphyloccus is the most common organism causing peritonitis in peritoneal dialysis (PD) patients, only one case of PD peritonitis due to Staphylococcus auricularis, the normal flora of external auditory meatus, has been reported over the world. Here we add a case of PD peritonitis caused by methicillin-resistant Staphylococcus auricularis, which was successfully treated with vancomycin. A 79-year-old male PD patient was admitted because of abdominal pain and cloudy peritoneal fluid. At admission, the exit site was clear, and no rebound tenderness was noted although the abdominal wall was diffusely tender. Gram stain of the peritoneal fluid did not reveal any organism, but white blood cell count was 1,210/mm3, with 80% polymorphonuclear cells and 10% lymphocytes. Empirical antibiotic therapy was started with intraperitoneal cefazolin and ceftazidime. Over the next few days, however, the peritoneal fluid was still turbid and showed an elevated cell count. Then, the result of peritoneal fluid culture identified that the organism was oxacillin-resistant Staphylococcus auricularis. Thus the antibiotics were switched into vancomycin, and intraperitoneal vancomycin 1 gm was administered three times at 5 days' intervals to achieve completely clear peritoneal fluid. Staphylococcus auricularis should be considered as a new potential skin organism causing PD peritonitis.

BACKGROUND/AIMS: Although high-flux (HF) dialyzers with enhanced membrane permeability are widely used in current hemodialysis (HD) practice, urea kinetic modeling is still being applied to indicate the adequacy of both low-flux (LF) and HF HD. In comparison with urea (molecular weight, 60 Da) and beta2-microglobulin (beta2MG, 12 kDa), cystatin C (CyC, 13 kDa) is a larger molecule that has attractive features as a marker for assessing solute clearance. We postulated that CyC might be an alternative for indicating the clearance of middle molecules (MMs), especially with HF HD. METHODS: Eighty-nine patients were divided into LF and HF groups. Using single pool urea kinetic modeling, the urea reduction ratio (URR) and equilibrated Kt/Vurea (eKt/Vurea) were calculated. The serum CyC concentrations were measured using particle-enhanced immunonephelometry. As indices of the middle molecular clearance, the reduction ratios of beta2MG and CyC were calculated. RESULTS: The beta2MG reduction ratio (beta2MGRR) and CyC reduction ratio (CyCRR) were higher in the HF group compared to the LF group. However, the URR and eKt/Vurea did not differ between the two groups. The CyCRR was significantly correlated with the eKt/Vurea and beta2MGRR (r = 0.47 and 0.69, respectively, both p < 0.0001). CONCLUSIONS: Compared to the LF dialyzer, the HF dialyzer removed CyC and beta2MG more efficiently. Unlike the beta2MGRR, the CyCRR was correlated with the eKt/Vurea and beta2MGRR. This study suggests a role for the CyCRR as an alternative indicator of the removal of MMs.

Takayasu arteritis is a nonspecific granulomatous inflammatory arteriopathy of unknown cause that results in occlusive obliteration and less commonly aneurysmal degeneration of large and medium-sized elastic arteries. The diagnosis of Takayasu arteritis and the assessment of its progression and extent remain challenging, especially in patients presenting with a constellation of non-specific symptoms and laboratory tests. The standard diagnostic procedures include biopsy, arteriography, sonography, and magnetic resonance angiography. However, these procedures are invasive or largely operator-dependent, and document only morphological changes such as stenosis, occlusion and aneurysmal transformation which mainly occur in late stages of the disease. On the other hand, Positron-emission tomography is an operator-independent, non-invasive metabolic imaging modality which plays a major role in diagnosis of nonspecific inflammatory diseases. We report a case in which Positron-emission tomography was applied to the detection of Takayasu arteritis and assessment of its disease progression.

Peritoneal dialysis is an important therapeutic option for patients with end-stage renal disease, and the peritoneal membrane is the lifeline for peritoneal dialysis patients. Therefore, strategies to maintain the health of the peritoneal membrane are very important. A 64-year-old female who had been undergoing continuous ambulatory peritoneal dialysis (CAPD) for the past 6 years was admitted because of painless gross hematuria. On abdominal computed tomography (CT), a mass was found in her left renal pelvis. A nephroureterectomy was performed via a retroperitoneal approach without any complications. Peritoneal dialysis was resumed 4 hours later. We report peritoneum-preserving nephroureterectomy via a retroperitoneal approach in a patient on CAPD.

Anti-glomerular basement membrane disease is a rare autoimmune disease characterized by rapidly progressive renal failure and/or pulmonary hemorrhage. The presence of severe crescentic glomerular inflammation with linear deposition of immunoglobulin G along the glomerular basement membrane is pathognomonic. Because renal function is rapidly and often irretrievably destroyed, many patients require hemodialysis all through their lifetime. We report a case of 33 year(s)-old man who was diagnosed as anti-glomerular basement membrane disease without pulmonary hemorrhage. The patient was treated with pulse methylprednisolone and plasmapheresis followed by oral corticosteroid and cyclophosphamide. His renal function was successfully recovered with early diagnosis and aggressive treatment.

BACKGROUND: Kidney transplant patient have a higher quality of life (QOL) and consume fewer health care resources compared to patients on dialysis. The purposes of this study were to compare the QOL in transplant patients and dialysis patients, and to provide basic materials necessary for enhancing their perceived QOL through conducting a survey. METHODS: The subjects of this study were 108 kidney transplant patients performed in our center, from 1990 to 2007, and 46 dialysis patients. These data have been collected from August to September in 2007 by a structured questionnaire about QOL consists of 42 items that assess 6 aspects; Affective state, Social activities, Somatic symptoms, family relationship and financial situation, attitudes toward life, and perceptions of health. We analyzed the collected data through T-test, frequency analysis, and one way ANOVA by employing a statistics package, SPSS 12.0 and we used Cronbach's Alpha Coefficient to verify accuracy and reliability of the measurement tools. RESULTS: Kidney transplant patients were shown statistically significant higher QOL than the dialysis patients, in affective state (P=.000), social activities (P=.001), somatic symptoms (P=.000), attitudes toward life (p=.000), and perceptions of health (P=.000). In family relationship and financial situation (P=.202), transplant patients were shown higher scores than dialysis patients, but there were not statistically significant differences. CONCLUSIONS: We suggest that kidney transplant patients enjoy higher QOL than dialysis patients with statistically significant differences, and there also showed different levels of the QOL according to general characteristics and disease-related features between the two types of patients.

PURPOSE: Clinical treatment for lupus nephritis largely depends upon histological renal biopsy classification. But it has been reported that serologic biochemical markers are not strongly associated with pathologic classification. The aim of this study is to see whether serologic markers could predict pathologic class of lupus nephritis for appropriate treatment. METHODS: We investigated 67 patients, who underwent renal biopsy with lupus nephritis at Hanyang University Hospital between January, 2005 and August, 2007. Biological markers for this study are hematuria, proteinuria, serologic data of lupus activity and azotemia. They were retrospectively analyzed from patients grouped by ISN/RPS 2003 lupus nephritis classification. RESULTS: Total 67 patients (men 5, women 62) were enrolled and the mean age of the patients was 30.6+/-9 years. The number of patient group by pathologic classification was 4 cases for class II, 15 cases for class III, 30 cases for class IV and 15 cases for class V. Spot urine protein to creatinine ratio more than 3 increased in class IV group statistically (p=.007). C3 level decreased more in class IV group than class III, V groups. Ten patients showed azotemia, and 9 of them were class IV group (p=.048). CONCLUSION: The patients with more increased proteinuria, decreased C3 level and azotemia showed more frequently in class IV group. Hence those three biological markers may be a clinical clue to pathologic diagnosis.

The incidence of malignant disease increases in kidney transplant recipients taking immunosuppressive therapy. Extramammary Paget's disease, a very rare dermatologic malignancy, is characterized by frequent recurrences and coexistence with other malignancies. Although skin cancer is the most common malignancy occurring after kidney transplantation, extramammary Paget's disease has not been reported in Korea. In this paper, we report a case of recurrent extramammary Paget's disease after renal transplantation. A 66-year old man, who underwent renal transplantation from a living unrelated donor 15 years ago, was diagnosed to have extramammary Paget's disease 7 years ago. At this admission he was troubled with a pruritic skin lesion in his suprapubic area which previously occurred twice. The recurring Paget's disease was treated with radical resection and coverage. No further recurrences have been developed during the following 12 months until now.
