Clinical and histological correlation of diabetic nephropathy.

Renal failure in diabetes is a common cause of renal replacement therapy. The affected kidney goes through various changes in all compartments progressively. The classification of diabetic nephropathy is based on glomerular lesions and displays a heterogeneous morphology. Abnormalities in tubulointerstitial and vascular compartments are important in assessing the outcome of these patients. We applied the new pathologic classification of diabetic nephropathy by Tervaert et al to classify the renal damage in diabetes. This is a prospective study over two years. We analyzed 74 renal biopsies in diabetic patients, both type-1 and type-2. Indications for biopsy were rapid onset of proteinuria, absence of retinopathy, presence of hematuria, active urine sediment, and rapid unexplained deterioration of renal function. Biopsy was done to rule out nondiabetic renal disease or any other associated pathology with diabetic nephropathy. In our study, 53 patients were male and 21 patients were female. Age ranged from 27 to 82 years. The mean ± standard deviation age at the time of the biopsy was 54.09 ± 11.59 years. Mean duration of diabetes was 10.2 years. Proteinuria ranged from 1 to 26 g. Type-111 histopathological lesion was the most common lesion observed in our series. There was a correlation between the degree of tubulo-interstitial damage with renal function. There was no correlation between the fundal changes and degree of proteinuria with the histological class of diabetic nephropathy. Application of the classification by Tervaert et al to diabetic lesions reduces the inter-observer variability and also helps in prognosticating and management of patients.

Prophylaxis against fungal peritonitis in CAPD--a single center experience with low-dose fluconazole.

BACKGROUND/AIMS: Fungal peritonitis (FP) significantly alters the outcome of patients on peritoneal dialysis (PD). Exposure to antibiotics is a risk factor for subsequent FP. Antifungal prophylaxis has been tried, with varying success, to prevent the occurrence of antibiotic-related fungal peritonitis (AR-FP). We aimed to evaluate the effect of prophylaxis with a low dose of fluconazole, in preventing AR-FP. METHODS: In this retrospective review, we examined the incidence of FP in a cohort of 115 patients, who had received antibiotics for bacterial peritonitis and received a co-prescription of fluconazole, 50 mg/day for the duration of antibiotic therapy. The incidence of bacterial peritonitis and FP for up to 3 months after antibiotic therapy was noted. RESULTS: One hundred and fifteen patients were followed up over a 6-year period, for 2549 patient-months. We observed 82 episodes of bacterial peritonitis and a total of 137 antibiotic prescriptions. The peritonitis rate was 1 episode per 31.08 patient-months (1 per 2.58 patient-year, 0.38 episodes every patient-year). We had six episodes of FP. There were no episodes of AR-FP. CONCLUSION: We observed very low rates of both bacterial peritonitis and FP, and prophylaxis with low-dose fluconazole seemed to confer protection against AR-FP. We did not encounter any adverse effects with its use.

Ultrasound-guided femoral dialysis access placement: a single-center randomized trial.

BACKGROUND AND OBJECTIVES: Insertion of dialysis catheters (DCs) is a prerequisite for successful initiation of hemodialysis. We attempted to determine if ultrasonography-guided (USG) insertion was superior and safer than the anatomical landmark-guided technique (ALT) for the femoral vein (FV). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a randomized prospective study on 110 patients requiring FV DCs in a tertiary care hospital. Patients were randomized into two groups: USG and ALT. Data were collected on demography, operator experience, and side of insertion. The USG group had their catheters inserted under USG guidance, whereas the ALT group had their DC inserted by ALT. Outcome measures included successful insertion of DC, number of attempts, and complications. RESULTS: Both groups were comparable regarding age and gender of patients, operator experience, and the side of catheterization. The overall success rate was 89.1%, with 80% using ALT and 98.2% under USG guidance (P = 0.002). First attempt success rate was 54.5% in the ALT group as compared with 85.5% in the USG group (P = 0.000). The complication rate was 18.2% in the ALT group and 5.5% in the USG group (P = 0.039). The odds ratio (OR) for complications with two or more attempts was 10.73 with a relative risk (RR) of 3.2. The OR for successful insertion using USG was 13.5 (95% CI: 1.7 to 108.7). CONCLUSIONS: USG significantly improves success rate, reduces number of attempts, and decreases the incidence of complications related to FV DC insertion.
