Background:Protein-energy wasting (PEW) and heightened inflammation are prevalent in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and is a strong risk factor for morbidity and mortality in these patients. Evaluation of PEW, prevalence of inflammation as well as interrelationship between various nutritional indices and inflammation has not been studied in much detail in patients undergoing CAPD.Objectives:This study was conducted to evaluate the interrelationship between PEW and inflammation in patients undergoing CAPD.Patients and Methods:Sixty-three patients undergoing CAPD (M = 28, F = 35) were assessed with regard to their nutritional status and inflammation after a minimum of 3 months CAPD initiation. Nutritional status was assessed by dietary diary, anthropometry, subjective global assessment, and multifrequency bioelectrical impedance analysis (BIA). In addition, their serum albumin, prealbumin, transferrin, and cholesterol level were measured. Also, inflammation in these patients was assessed by High-Sensitivity C-Reactive Protein (hs-CRP > 3 mg/L) and Interleukin-6 (IL-6 > 2 µg/mL). Later on, diagnosis of malnutrition was made based on different methods. Correlation between inflammation and various nutritional assessment indices were analyzed statistically.Results:Mean (SD) age of the patients was 57.6 (11.6) years. The average (SD) calorie and protein intake per day were 25.5 (4.6) kcal and 0.81 (0.2) mg, respectively. The mean and standard deviation of anthropometry variables of body mass index (BMI), mid-arm circumference (MAC), tricipital skin-fold thickness (TST), mid-arm muscle circumference (MAMC), and corrected mid-arm muscle area (cMAMA) were 23.7 ± 5 kg/m2, 26.3 ± 4.5 cm, 1.624 ± 0.4 cm, 25.6 ± 4.5 cm, and 45.7 ± 19.7 cm2, respectively. The mean values of serum protein, albumin, prealbumin, transferrin, cholesterol, triglyceride, hs-CRP, and IL-6 were 5.9 g/dL, 3.0 g/dL, 21.11 mg/dL, 130.6 mg/dL, 155.9 mg/dL, 136.1 mg/dL, 8.8 ± 7.6 mg/L, and 8.4 ± 12.2 µg/dL, respectively. Based on subjective global assessment (SGA); 11.63 (17.4%), 34.63 (54%), and 18.65 (28.6%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. According to serum albumin level; 13.63 (21%), 39.63 (62%), and 11.63 (17%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. Finally, based on BMI; 33.63 (52%), 23.63 (37%), and 7.63 (11%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. About 76.1% and 9.5% of patients undergoing CAPD were malnourished based on lean tissue index (LTI) and fat tissue index (FTI), respectively. Based on hs-CRP and IL-6 findings, 70% (44/63) and 71.8% (45/63) of patients undergoing CAPD had high inflammation, respectively. High sensitive C-reactive protein correlated negatively (significantly) with serum albumin, prealbumin, and transferrin. Interleukin -6 correlated negatively (significantly) with MAC; MAMA; serum albumin, cholesterol, and transferrin. T...
Background:Milky urine can be due to chyluria or lipiduria due to nephrotic syndrome. Filarial chyluria usually responds to medical management while non-filarial cases may require surgical intervention.Aim:To perform a prospective observational study in patients presenting with milky urine in our centre over a period of one year from July 2011 to June 2012, a complete biochemical work up and imaging to find out the site of leakage of lymph if it is a case of chyluria, its response to medical management and the requirement of surgical intervention.Materials and Methods:Routine blood and urine investigations, 24 hour urine protein excretion, USG abdomen, serum lipid profile and rapid filarial antigen test were done in all. MRI abdomen was done in affordable patients. Renal biopsy was done in some chyluria patients for academic purpose and in milky urine with negative urine ether test. Sclerotherapy was done with 50% dextrose and 0.2% povidone iodine. Patients were followed up with 24 hour urine protein and triglyceride estimation.Results:18 cases of milky urine were encountered. 8 were filarial chyluria, 9 non- filarial and 1 MCD. Mean urine TG level and median 24 hour urinary protein excretion were 37.2 ± 24.6 mg% and 4.96 g respectively. The mean age for filariasis (22.9 ± 4.5 years) was significantly different from that of non-filarial etiology (31.5 ± 4.8 years) (P = 0.005). The mean 24 hour urinary protein for normal MRI cases (4.64 ± 0.70 g) was significantly different from those with dilated lymphatics (8.15 ± 2.55 g) (P = 0.02). All the non- filarial and 4 filarial cases required sclerotherapy. One patient required a second sitting.Conclusion:Milky urine is most commonly due to chyluria and occasionally due to nephrotic syndrome. Nephrotic syndrome is managed in its own way while chyluria not amenable to pharmacological intervention is managed with sclerotherapy.
