Dietary Management in Slowing Down the Progression of CKDu.

Chronic kidney disease of unknown etiology (CKDu) is an emerging entity in the South Asian region. This predominately affects the farming community belonging to the lower socioeconomic status. CKDu being a progressive condition often leads to end-stage renal failurerequiring renal replacement therapy (RRT). Due to the high cost and limited availability of RRT in many areas of geographical locations in India and worldwide, there is an unmet need to slow down the progression of CKDu. The intestinal microbiota is different in patients with CKD, with low levels of beneficial bacteria such as Lactobacillus and Bifidobacteria. Prebiotics and probiotics modify the intestinal microbiota and thereby slow down the progression. Soda bicarbonate therapy is cheap and cost-effective in slowing down the progression of CKDu in a subset of patients. There is also evidence of the beneficial effect of N-acetyl cysteine in early stages of CKD and it should benefit CKDu also. Dietary interventions to prevent dehydration, by providing uncontaminated drinking water, sufficient protein containing diet with adequate calories, and tailored salt intake to prevent hypotension, are necessary compared to other causes of CKD. The objective is to prevent malnutrition, and uremic symptoms. Early diagnosis and prompt intervention may delay the progression of CKDu in the early stages.

Twenty-one episodes of peritonitis in a continuous ambulatory peritoneal dialysis patient: What is the root cause?

A 51-year-old female, with non-alcoholic liver cirrhosis, portal hypertension, type 2 diabetes mellitus, autosomal dominant polycystic kidney disease with a clipped cerebral aneurysm and chronic kidney disease stage 5 was on continuous ambulatory peritoneal dialysis (CAPD) for 6.5 years elsewhere. She came for opinion on continuation of CAPD as she had 21 episodes of peritonitis in 76 months. Her blood pressure was 80/50 mmHg. She was on haemodialysis with a temporary central access for 2 weeks. She had no abdominal tenderness, and exit site looked normal. Fluid was negative for Mycobacterium tuberculosis. Laparoscopically, we replaced the catheter with a new swan-neck Tenckhoff double-cuff catheter through a different exit site in the same sitting. Catheter-tip biofilm culture isolated Enterococcus casseliflavus. Peritoneal sampling biopsy showed evidence of fibrosis. She has adequate ultrafiltration and is currently on automated peritoneal dialysis for 5 months.
