A 63-year-old woman was admitted due to right upper quadrant abdominal pain. She was going through hemodialysis due to end stage renal disease and taking calcium polystyrene sulfonate orally and rectally due to hyperkalemia. Colonoscopy showed a circular ulcerative mass on the proximal ascending colon. Biopsy specimen from the mass showed inflammation and necrotic debris. It also revealed basophilic angulated crystals which were adherent to the ulcer bed and normal mucosa. These crystals were morphologically consistent with calcium polystyrene sulfonate. She was diagnosed with calcium polystyrene phosphate induced colonic necrosis and improved with conservative treatment.

Diabetes is a rapidly increasing heath care problem all over the world due to increased prevalence during past decade. Diabetic nephropathy develops in 25-30% of patients with type 1 diabetes and is the leading cause of end stage renal disease. Diabetic nephropathy is characterized by persistent proteinuria, decline in renal function, hypertension and increased cardiovascular morbidity and mortality. Early detection of diabetic nephropathy risk is an important goal because early diagnosis and treatment prevent advanced renal damage and other diabetic complications. Increased urinary albumin excretion rate is widely accepted as the first clinical sign of diabetic nephropathy. However, reduced glomerular filtration or hypertension could be the first manifestation in some diabetic patients. We need improved markers and predictors of diabetic nephropathy risk. We report a case of diabetic nephropathy and decreased glomerular filtration rate (GFR) without microalbuminuria occcured in type 1 diabetic patient.

Renal transplantation is the treatment of choice for patients with chronic renal failure, which produces a dramatic improvement in the quality of life and survival rates, in comparison to long-term dialysis. Nowadays, new imaging modalities allow early diagnosis of complications, and thanks to the recent developments of interventional techniques, surgery may be avoided in most cases. Knowledge in the types of renal transplant complications is fundamental for a correct pre-operative planning. In this article, we described the most common or clinically relevant renal transplant complications and explained their interventional management.

PURPOSE: Co-morbidity is the presence of co-existing or additional diseases during the initial diagnosis. It may be used as a prognostic indicator for the postoperative outcomes in most cancers, including colorectal cancers. The impact of respective co-morbidities in colorectal cancer surgeries were evaluated to identify their outcomes regarding complications and hospital stay. METHODS: The medical records of 2,242 colorectal cancer patients, who had had curative operations between Jan. 1997 and Dec. 2001, were reviewed to evaluate the prevalence of co-morbidities. All co-morbidities were adequately evaluated and managed preoperatively. RESULTS: Co-morbidities were observed in 789 out of the 2,242 (35.2%) patients. Hypertension was the most frequent (340, 15.2%), with diabetes (210, 9.4%) and cardiovascular diseases (124, 5.5%) following. Early stages (0~II) were more frequently associated with co-morbidities, compared to late stages (III~IV) (P<0.001). Hypertension and cerebrovascular diseases were significantly associated with postoperative complications (P<0.05). Postoperative complications occurred in 578 out of the 2242 (25.8%) patients: e.g., ileus (10.2%), voiding difficulty (4.4%), wound problems (4.3%), etc. Pulmonary complications occurred more often in patients with cerebrovascular diseases, hypertension, and asthma. Wound complications were observed in patients with hypertension, cerebrovascular diseases, chronic obstructive pulmonary disease, and chronic renal failure (P<0.05). Patients with more than one co-morbidity were closely associated with frequent postoperative co-mplications (P<0.05). However, comorbidities did not seem to affect the duration of the postoperative hospital stay. CONCLUSIONS: Postoperative complications frequently occur in colorectal cancer patients with specific co- morbidities, especially in those with more than one. An adequate management of the co-morbidities preoperatively leads to a good outcome.

We report five cases of cytomegalovirus infection in immunocompromised patients which were detected by either cytomegalovirus antigenemia assay or in situ hybridization. Four cases had leukemia and the other had chronic renal failure. All the three BMT recipients suffered from GvHD. Interestingly, there was an unique case of CMV disease without a history of BMT, which reminded us that CMV could attack immunocompromised patients who had not undergone transplantation, too. Four out of five cases died. We think that cytomegalovirus infection or disease should not be regarded as a minor problem in post-transplantation infection in Korea.

Leptin serves an important role in suppressing appetite in mice and is known to be elevated in chronic renal failure (CRF) patients. But clinical significance of leptin as an appetite-reducing uremic toxin, remains to be determined. So we studied the relationship between plasma leptin and nutritional status in 46 chronic hemodialysis (HD) patients. Pre HD leptin was measured and divided by body mass index (BMI) to give adjusted leptin levels. KT/Vurea (K, dialyzer urea clearance; T, duration of HD; V, volume of distribution of urea), C-reactive protein (CRP), plasma insulin and nutritional parameters such as serum albumin, normalized protein catabolic rate (nPCR), subjective global assessment (SGA), BMI and mid-arm muscle circumference (MAMC) were also measured. Mean plasma leptin levels were 8.13+/-2.91 ng/mL (male 3.15+/-0.70; female 14.07+/-6.14, p<0.05). Adjusted leptin levels were positively correlated with nPCR (male r=0.47, p<0.05; female r=0.46, p<0.05), SGA (male r=0.43, p<0.05; female r=0.51, p<0.05) and MAMC (male r=0.60, p<0.005; female r=0.61, p<0.05). They did not correlate with KT/Vurea, serum albumin, hematocrit, bicarbonate, insulin and CRP. Presence of DM and erythropoietin therapy had no effect on leptin levels. These results suggest that leptin is a marker of good nutritional status rather than a cause of protein energy malnutrition in chronic HD patients.

OBJECTIVES: Platelet-to-lymphocyte ratio (PLR) has recently been investigated as a new inflammatory marker in many inflammatory diseases, including systemic lupus erythematosus and immunoglobulin A vasculitis. However, there were very few reports regarding the clinical role of PLR in patients with anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis. This study was thus undertaken to investigate the relationship between inflammatory response and disease activity in Chinese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis. Furthermore, we evaluated whether PLR predicts the progression of end stage of renal disease (ESRD) and all-cause mortality. METHODS: The clinical, laboratory and pathological data, and the outcomes of MPO-ANCA associated vasculitis patients were collected. The Spearman correlation coefficient was computed to examine the association between 2 continuous variables. Cox regression analysis was used to estimate the association between PLR and ESRD or all-cause mortality. RESULTS: A total of 190 consecutive patients with MPO-ANCA associated vasculitis were included in this study. Baseline PLR was positively correlated with CRP (r=0.333, P<0.001) and ESR (r=0.218, P=0.003). PLR had no obvious correlation with Birmingham Vasculitis Activity Score (BVAS). Patients having PLR≥330 exhibited better cumulative renal survival rates than those having PLR<330 (P=0.017). However, there was no significant difference in the cumulative patient survival rates between patients with PLR≥330 and those with PLR<330 at diagnosis (P>0.05). In multivariate analysis, PLR is associated with the decreased risk of ESRD (P=0.038, HR=0.518, 95% CI 0.278 to 0.963). We did not find an association between PLR with all-cause mortality using multivariate analysis (HR=1.081, 95% CI 0.591 to 1.976, P=0.801). CONCLUSIONS PLR is positively correlated with CRP and ESR. Furthermore, PLR may independently predict the risk of ESRD.

Lower gastrointestinal complications often develop in end stage renal disease patients, and among the more problematic is recurrent colon ulcer. The exact pathogenesis of this condition is not known and there were no specific therapeutic modalities concerning this type of disease entity. We report, with a literature review, a case of recurrent colon ulcer with intermittent hematochezia in an end stage renal disease patient on long term hemodialysis that improved after conversion to peritoneal dialysis.
