A Case of Perforated Acute Cholecystitis in CAPD Patient who Returned to CAPD after Laparoscopic Cholecystectomy / 대한신장학회지

We experienced a 59 year-old female diabetic CAPD patient with severe peritonitis due to perforated acute cholecystitis. Because of heart failure due to old myocardial infarction and cerebral infarction she had been treated with CAPD for 5 years in bed-ridden state. Initial presentation was dark brown colored peritoneal dialysate effluent (changed greenish bile color later) and septic shock. We diagnosed perforated acute cholecystitis by computerized tomography three days after improvement of sepsis. She was received laparoscopic cholecystectomy and continuous venovenous hemodiafiltration for two weeks and returned to peritoneal dialysis without complication. Secondary CAPD peritonitis with cholecystitis or bowel disease should be carefully considered in patients with specific dialysate color, which could be cured with laparoscopic surgery, and then patients can be returned to CAPD again without complication.

The Clinical Differentiations between Diabetic Nephropathy and Non-diabetic Renal Disease in Type 2 Diabetic Patients / 대한신장학회지

PURPOSE: It is important to differentiate non-diabetic renal diseases (NDRD) from diabetic nephropathy (DN) in type 2 diabetes. Our study was reviewing the clinical data and treatment strategies from diabetic patients performed renal biopsy to determine the clinical indicators suggestive of NDRD METHODS: We reviewed the medical records of type 2 patients who underwent renal biopsy from Jan. 1995 to Dec. 2007. RESULTS: Seventy four patients were included. Mean age was 52.0+/-12.5 years and 41 (55%) patients were male suddenly developed. Nephrotic syndrome [34 cases (46%)] was the leading reason for renal biopsy. There were 37 cases (50%) with a pathologic diagnosis of DN, 31 (42%) with NDRD, and 6 (8%) with concurrent DN and NDRD. IgA nephropathy (35%) was the most common lesion found in patients with NDRD. Thirty one patients (84%) with DN and 26 (84%) with NDRD had follow-up periods of more than 6 months. Of 26 patients with NDRD, 12 were treated with immune suppressants and 6 achieved complete remission. Thirteen patients with DN and one with NDRD developed end-stage renal disease. Patients with NDRD tended to show shorter duration of diabetes, lower systolic blood pressure (SBP) and lower serum triglyceride, and had significantly lower incidence of diabetic retinopathy (DR). In the univariate regression analysis, diabetes duration, SBP, triglyceride and DR showed statistically significance. And SBP and DR were identified as independent correlating factors by multivariate regression analysis. CONCLUSION: In this study, the absence of retinopathy could predict the presence NDRD among NIDDM patients presenting with renal disease. And additional disease-specific therapies may be helpful for the patients with NDRD.

Changes of Intracellular Water by Hemodialysis in Diabetic and Non-diabetic ESRD Patients: Analysis with MF-BIA / 대한신장학회지

PURPOSE: During hemodialysis, various methods are used to evaluate adequate water removal; however, few of them are currently clinically applicable. To evaluate the differences of body fluid changes, we have compared changes of ICW (intracellular water) and ECW (extracellular water) before and after hemodialysis in diabetic and non-diabetic patients with MF-BIA. Also various factors influencing in this transcellular body fluid shift were evaluated. METHODS: TBW (total body water), ICW, ECW were measured before and after hemodialysis by using MF-BIA in 85 stable maintenance hemodialysis patients in a university hospital. Among these patients, 30 patients (mean age 55.6+/-12.4 year-old, average dialysis duration 26 months) were diabetic, while 55 patients (mean age 47.1+/-13.0 year-old, average dialysis duration 69 months) were non-diabetic. RESULTS: ECW/TBW in diabetic and non-diabetic patients were 0.338+/-0.02, 0.334+/-0.02, respectively. There was no significant difference between two groups. There were also no significant differences in the sex, age, duration of dialysis, BMI, hemoglobin, total protein, osmolarity of ICW loss/TBW removal. But there was a significant positive correlation between the increase in ultrafiltration volume (UFV:%) and ICW loss in diabetic patients (R=0.51, p=0.019); however, such correlation was not observed in non-diabetic patients. CONCLUSION: We found that ICW of diabetic patients moved to extracellular spaces even before achieving appropriate dry body weight or less amount of fluid was removed compared to non-diabetic patients. This finding might imply diabetic ESRD patient has relatively low cellular membrane integrity and oncotic pressure maintenance ability to physical transmembrane pressure.

Clinical Characteristics of Acute Myocardial Infarction in Dialysis Patients / 대한신장학회지

PURPOSE:Cardiovascular disease is the predominant cause of death in patients with end stage renal disease. Approximately 33.7% of overall mortality is due to cardiovascular disease, and about 27% of these cardiovascular deaths are attributed to acute myocardial infarction (AMI). Despite the significance of AMI, there are little data on the clinical characteristics of AMI in dialysis patients. METHODS:Thirty-two dialysis patients admitted for AMI from January 2004 to December 2007 were retrospectively analyzed. One hundred twenty-three AMI patients were included as a control. The clinical and laboratory findings of AMI were compared between dialysis patients and non-dialysis patients. RESULTS:The frequency of typical chest pain was significantly lower in dialysis patients than in non- dialysis patients (18.8% vs. 62.6%, p<0.001), and typical ECG findings of STEMI were significantly less noted (28.1% vs. 82.9%, p<0.001). Increases in CPK, CK-MB, and troponin T levels were significantly lower in dialysis patients than in non-dialysis patients ( p<0.001). In contrast, dialysis patients revealed more multi-vessel diseases on coronary angiography and more left ventricular hypertrophy and were associated with higher mortality during admission than non-dialysis patients. CONCLUSION:Although dialysis patients with AMI had less typical chest pain and typical ECG findings, and had lower increases in cardiac enzyme levels, they revealed more severe coronary vessel diseases than non-dialysis patients. Therefore, efforts for early and accurate diagnosis of AMI are needed in dialysis patients with nonspecific complaints of AMI.

Comparison of the 13C-urea breath test and the endoscopic phenol red mucosal pH test in the quantification of Helicobacter pylori infection loading

BACKGROUND/AIMS: The 13C-urea breath test (UBT) is a semiquantitative test for measuring Helicobacter pylori infection loading. H. pylori produces ammonia, which elevates the pH of the gastric mucosa and is detectable via endoscopy using a phenol red indicator. We evaluated whether this test could be used to diagnose H. pylori infection and whether phenol red staining was correlated with 13C-UBT results. METHODS: One hundred and twenty-three patients participated. The UBT was performed after ingestion of a capsule containing urea. A change in 13C-UBT >2 ppt was selected as the cutoff value for diagnosing infection. After spraying evenly with a 0.1% phenol red solution, the pH of the gastric mucosal surface was measured using an antimony electrode through the biopsy channel. RESULTS: The pH of stained mucosa (6.9+/-0.4) was significantly higher than that of unstained mucosa (1.9+/-0.8; p<0.001), and the H. pylori detection rate confirmed via histology was higher in stained versus unstained mucosa (p<0.01). Extensive mucosal staining resulted in a higher detection rate (p<0.001). The UBT produced results were very similar to those obtained via histological detection in stained mucosa (p<0.001). The extent of staining, expressed as a staining score, was positively correlated with the change in 13C-UBT (r=0.426, p<0.001). A significant correlation was also observed between the histologically determined H. pylori density and 13C-UBT results (r=0.674, p<0.001). CONCLUSIONS: H. pylori infection elevates gastric mucosal surface pH, and endoscopic phenol red staining may be an alternative method for the diagnosis of H. pylori infection.

A case of congenital bilateral coronary-to-right ventricle fistula coexisting with variant angina

A coronary arteriovenous (AV) fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common anomaly that can affect coronary perfusion. Yet bilateral involvement of a coronary fistula, constitutes an uncommon subgroup of coronary AV fistulas. We herein report on a case of bilateral coronary AV fistula that was coexistent with variant angina originating from the distal right ventricular branch of the right coronary artery and the distal septal branch of the left anterior descending artery, and the latter drained into the right ventricle.

A Case of Primary Colonic Lymphoma with Peritoneal Carcinomatosis and Pleural Effusion / 대한소화기내시경학회지

Primary gastrointestinal lymphomas are quite rare with the stomach and small bowel being the most frequent site. Colon involvement is observed in only 10~20% of all gastrointestinal lymphomas. A colonic lymphoma presents with non-specific abdominal pain, weight loss, a change in bowel habits, bleeding, intestinal obstruction, intussusception and a palpable mass. A colonic lymphoma can be indicated using a barium enema, abdominal CT and colonoscopy. The correct diagnosis is obtained by a colonoscopic biopsy. We report a case of primary colonic non-Hodgkin's lymphoma with peritoneal carcinomatosis and a right pleural effusion.

A Case of Poststreptococcal Glomerulonephritis Representing Rapidly Progressive Glomerulonephritis in an Elderly Patient / 대한신장학회잡지

Postinfectious streptococcal glomerulonephritis (PSGN) presenting as a rapidly progressive glomerulonephritis (RPGN) and nephrotic syndrome (NS) is a rare disease in elderly patients. Here we report a case of PSGN with RPGN and NS in an elderly male patient with a complete recovery from his illness. A 73-year-old man was admitted for dyspnea, oliguria and generalized edema appearing after acute upper respiratory infection. On admission, he presented nephrotic range of proteinuria, decreased renal function with elevated ASO, and decreased C3 and CH50 concentrations. The renal biopsy showed marked cellular crescents in the glomeruli with collapsed glomerular tufts and inflammatory cell infiltration. There were prominent and various sizes of "humps" in subepithelial areas in electron microscopy. Under the diagnosis of PSGN with RPGN, we successfully treated the patient with steroid pulse therapy and hemodialysis. We would suggest that early diagnosis and aggressive steroid therapy should be indicated in the treatment of PSGN with RPGN.

Chinese Herbs Induced End-Stage Renal Disease in a Patient with Minimal Change Nephrotic Syndrome / 대한신장학회잡지

An outbreak of rapidly progressive renal failure was observed in Belgium in 1993 and was related to a slimming regimen involving Chinese herbs. Extensive interstitial fibrosis with atrophy and tubular loss was the major histological lesion. Aristolochic acid has been suspected to be responsible for nephrotoxicity. The use of Chinese herbal medicines is very popular in Korea. We report the presence of a nephrotoxic compound in herb medications, which led to end-stage renal failure in a patient with complete remission state of minimal change disease. The typical and sequential pathologic changes in our patient following the consumption of herbs suggest possible relationship to herbal medicines, and end-stage renal disease, despite the fact that a cause-and-effect relationship cannot be automatically inferred.
