Abstract
INTRODUCTION Although vascular calcification is a recognised complication for haemodialysis patients, peritoneal dialysis (PD) patients are also at risk. As such we wished to review peritoneal and urinary calcium balance and the effect of calcium containing phosphate binders (CCPBs). METHODS Twenty-four-hour peritoneal calcium balance and urinary calcium were reviewed in PD patients undergoing their first assessment of peritoneal membrane function. RESULTS Results from 183 patients, 56.3% male, 30.1% diabetic, mean age 59.4 ± 16.4 years, median 2.0 (2-6) months of PD, 29% treated by automated PD (APD), 26.8% continuous ambulatory (CAPD) and 44.2% APD with a day-time exchange (CCPD) were reviewed. Peritoneal calcium balance was positive in 42.6%, and remained positive in 21.3% after including urinary calcium losses. PD calcium balance was negatively associated with ultrafiltration (odds ratio 0.99 (95% confidence limits 0.98-0.99), p = 0.005. PD calcium balance was lowest with APD (APD - 0.45 (- 0.78 to 0.05) vs CAPD - 0.14 (- 1.18 to 0.59) vs CCPD - 0.03) - 0.48 to 0.5) mmol/day), p < 0.05, with 82.1% of patients with a positive balance prescribed icodextrin, when combining peritoneal and urinary losses. When considering CCPB prescription, then 97.8% of subjects prescribed CCPD had an over-all positive calcium balance. DISCUSSION Over 40% of PD patients had a positive peritoneal calcium balance. Elemental calcium intake from CCPB had a major effect on calcium balance, as median combined peritoneal and urinary calcium losses were < 0.7 mmol/day (26 mg), so caution is required to prevent excessive CCPB prescribing, increasing the exchangeable calcium pool and thus potentially increasing vascular calcification, particularly for anuric patients.

Nutrients 2022; 14:nu14173553. [PMID: 36079811 PMCID: PMC9460881 DOI: 10.3390/nu14173553] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 08/25/2022] [Accepted: 08/25/2022] [Indexed: 11/28/2022] Open
Abstract
Protein-energy wasting (PEW) is considered one of the major complications of chronic kidney disease (CKD), particularly in dialysis patients. Insufficient energy and protein intake, together with clinical complications, may contribute to the onset and severity of PEW. Therefore, the aim of the study was to analyze the differences in nutritional and hydration status and dietary intake among Dalmatian dialysis patients. Fifty-five hemodialysis (HD) and twenty peritoneal dialysis (PD) participants were included. For each study participant, data about body composition, anthropometric, laboratory, and clinical parameters were obtained. The Malnutrition Inflammation Score (MIS) and two separate 24-h dietary recalls were used to assess nutritional status and dietary intake. The Nutrient Adequacy Ratio (NAR) and Mean Adequacy Ratio (MAR) were calculated to compare actual dietary intake with recommended intake. Additionally, the estimated 10-year survival was calculated using the Charlson Comorbidity Index. The prevalence of malnutrition according to MIS was 47.3% in HD and 45% in PD participants. Significant differences in fat tissue parameters were found between HD and PD participants, whereas significant differences in hydration status and muscle mass parameters were not found. A significant difference in NAR between HD and PD participants was noticed for potassium and phosphorus intake, but not for MAR. MIS correlated negatively with anthropometric parameters, fat mass, visceral fat level and trunk fat mass, and iron and uric acid in HD participants, whereas no significant correlations were found in PD participants. The estimated 10-year survival correlated with several parameters of nutritional status in HD and PD participants, as well as nutrient intake in HD participants. These results indicate a high prevalence of malnutrition and inadequate dietary intake in the Dalmatian dialysis population which, furthermore, highlights the urgent need for individualized and structural nutritional support.

Abstract
INTRODUCTION The nutritional status of old hemodialysis patients determines their prognosis. The aim of this study was to evaluate the spontaneous dietary intake of hemodialysis of elderly patients. METHODS This cross-sectional descriptive study included 40 elderly hemodialysis patients recruited at the M8 nephrology department of Charles Nicolle hospital in Tunis. All patients went through a clinical examination to specify anthropometric measurements and a dietary survey based on food registration for 3 consecutive days to obtain a nutritional assessment. RESULTS The evaluation of patients' energy intake showed an average daily intake of 25.3±12.3kcal/kg of ideal weight/day. The average total energy intake of patients on dialysis and non-dialysis days was 29.7±17.7kcal/kg and 20.9±6.9kcal/kg, respectively, with a statistically significant difference (P=0.001). The average daily protein intake was 0.99±0.57g/kg on the day of no dialysis. It decreased statistically significantly (P=0.005) on the day of no dialysis at 0.73±0.28g/kg. Phosphorus consumption was excessive on dialysis and non-dialysis days respectively in 20% and 3% of cases. Deficiency of calcium intake affected the entire population studied on the day of non-dialysis. Only 6% of patients had a calcium intake satisfactory on the day of dialysis. CONCLUSION A lot of dietary errors were noticed in our study. The assessment of nutritional intake in elderly people with hemodialysis should be part of their management systematically.

Abstract
The impressive estimated number of chronic kidney disease (CKD) patients in the world justifies any possible effort at implementing preventive measures of disease progression. Renal insufficiency is associated with significant changes in the electrolyte handling and body balance of sodium, potassium, phosphate, magnesium, and calcium, all of which are biologically vital molecules. Dietary habits could contribute significantly to the optimal management of possible derangements. In this review, we examined the available evidence recommending dietary prescriptions for these five elements aiming at reducing CKD progression. Clear evidence that specific dietary prescriptions may halt or reduce CKD progression is lacking. However, some practical recommendations are possible to prescribe the best possible therapy to the individual CKD patient.

Abstract
PURPOSE In low and middle- income countries, due to lack of financial resources, the number of patients receiving one or two hemodialysis (HD) sessions a week has increased, leading to a large number of complications. Protein-energy wasting (PEW) and overhydration (OH) are common complications; nevertheless, the evidence regarding the nutritional status of patients receiving 2 and 3 weekly dialysis sessions is scarce. Thus, our objective was to compare the nutritional and hydration status of patients with two and three HD sessions. Secondarily, we aimed to compare hospitalizations, infectious complications and mortality within the following 6 months after the initial assessment. METHODS Forty-four patients in a 3 weekly session scheme and 44 dialyzed twice a week were included. Anthropometrical, biochemical, dietary and impedance measurements were performed. Malnutrition Inflammation Score (MIS) and PEW score were applied. Number of hospitalizations, infectious complications and mortality during the 6 months following the evaluation were recorded. RESULTS Prevalence of moderate/severe undernutrition (63.6% vs 36.4%, p < 0.006) and prevalence of OH (90.9% vs 77.3%, p < 0.001) were significantly higher in the twice-weekly sessions group compared to the 3 weekly sessions. The twice a week session group showed a 3.7-fold (OR 3.7, 95% CI 1.3-10.5, p = 0.01), a 2.5-fold (OR 2.4, 95% CI 0.9-6.6, p = 0.01), a 4.5-fold (OR 4.5, 95% CI 1.0-20.2, p < 0.05), a 8.3-fold (HR 8.3, 95% CI 2.4-28.2, p = 0.001) and a 11.6-fold (HR 11.6, 95% CI 2.4-54.0, p = 0.002) increased odds of developing undernutrition, PEW, OH, being hospitalized or death, respectively, compared to those who received three sessions per week. CONCLUSIONS Twice weekly hemodialysis scheme is associated with higher odds of moderate or severe undernutrition, PEW, OH status, hospitalization and mortality compared to a thrice-weekly hemodialysis scheme.

Abstract
A rapid and reliable tool appropriate to quantifying macronutrient and micronutrient intakes in diets consumed by Malaysian hemodialysis (HD) patients is lacking. We aimed to develop and validate a novel HD-food frequency questionnaire (HD-FFQ) to assess habitual nutritional intakes of HD patients with diverse ethnic backgrounds. This study was conducted in three phases. In Phase I, a HD-FFQ comprising 118 food items was developed using 3-day diet recalls (3DDR) from 388 HD patients. Phase II was the face and content validation using the Scale-Content Validity Index (S-CVI). After successfully developing the FFQ, Phase III tested relative validation against a reference method, the 3DDR. Results from Phase III showed that the mean difference for absolute intakes of nutrients assessed by HD-FFQ and 3DDR were significant (p < 0.05). However, there was a significant correlation between the HD-FFQ and reference method ranging from 0.35–0.47 (p < 0.05). Cross-quartile classification showed that <10% of patients were grossly misclassified. In conclusion, the HD-FFQ has an acceptable relative validity in assessing and ranking the dietary intake of the HD patients in Malaysia.

Abstract
Background Nutritional factors are associated with high mortality and morbidity in dialysis patients, and protein-energy wasting is regarded as an important one. The modality of dialysis may affect patients’ dietary behavior and nutritional status, but no study has compared the dietary behavior, nutrient intake, and nutritional adequacy of hemodialysis (HD) and peritoneal dialysis (PD) patients. Methods From December 2016 to May 2017, a dietary behavior survey and Semi-quantitative Food Frequency Questionnaire (Semi-FFQ) were conducted on 30 HD patients and 30 PD patients in Ewha Womans University Mokdong Hospital, and laboratory parameters were obtained. The results of prevalent HD and PD patients were then compared. Results The mean age of HD patients was higher than that of PD patients; HD: 58.5 ± 9.1 years, PD: 49.3 ± 9.7 years (p = 0.001). In the dietary behavior survey, HD patients showed more appropriate dietary behavior patterns overall than PD patients. In the dietary intake analysis with the Semi-FFQ, energy intake was significantly lower in the PD group than in the HD group due to the lower intake of carbohydrates, fat, and protein. A comparison of nutrient intake-to-recommended allowance ratio between the HD and PD groups revealed that the HD group showed higher nutrient intake than the PD group. Serum albumin and potassium levels were significantly higher in HD than in PD patients. Conclusion According to this study, the dietary behavior and nutritional intake of prevalent PD patients were worse than those of HD patients.

Abstract
AbstractConstipation is highly prevalent in patients with chronic kidney disease (CKD) and is primarily characterized by decreased intestinal motility. This chronic disorder affects the quality of life of patients. However, nephrologist and dialysis clinicians have long had a disproportionately limited understanding of constipation. Accumulating evidence has revealed a relationship between constipation and cardiovascular disease and CKD. The pathogenesis of constipation in CKD patients is multifactorial: decreased physical activity, comorbidities affecting bowel movement, such as diabetes mellitus, cerebrovascular disease, and hyperparathyroidism, a restricted dietary intake of plant-based fiber-rich foods, and multiple medications, including phosphate binders and potassium-binding resins, have all been implicated. CKD is associated with alterations in the composition and function of the gut microbiota, so-called gut dysbiosis. Recent studies showed that CKD-related gut dysbiosis decreased intestinal motility via intestinal inflammation or the increased generation of gut-derived uremic toxins, such as indoxyl sulfate and p-cresyl sulfate. Furthermore, the gastrointestinal secretion of mucin was found to be decreased in CKD animal models, which may delay colonic transit by diminished lubrication in the alimentary tract. Thus, CKD-related gut dysbiosis may play a role in constipation, but limited information is currently available. Since constipation is often intractable, particularly in CKD patients, every available means needs to be employed in its treatment. The effects of probiotics, prebiotics, and synbiotics on the composition of the gut microbiota and gut-derived uremic toxins have been increasingly reported. However, their effects on stool consistency or frequency in CKD patients remain unclear. Some laxatives may be beneficial for improving not only bowel habits but also gut dysbiosis. Further studies are required to elucidate the CKD-specific pathogenesis of constipation and develop novel effective treatment options.

Abstract
OBJECTIVE Fiber intake influences disturbances in the gastrointestinal tract and is associated with systemic inflammation in the general population. Systemic and intraperitoneal inflammation play an important role in defining outcomes in peritoneal dialysis (PD), but the relationship between dietary fiber intake and inflammatory biomarkers has not yet been reported in the population on PD. The objective of the present study is to analyze whether or not fiber intake in patients on PD is associated with serum and intraperitoneal levels of inflammatory biomarkers. DESIGN AND METHODS Adult and clinically stable PD patients were included in this observational and cross-sectional study. Fiber intake was assessed by means of a dietary survey and calculated using the DietPro program 5.6i. The population was divided into two groups according to the median fiber intake. We investigated interleukin (IL)-1β, IL-6, tumor necrosis factor-α, monocyte chemoattractant protein-1 (MCP-1), B-cell-activating factor, and plasminogen-activator inhibitor-1 in both serum and peritoneal fluid. The latter was determined after a dwell time of 4 hours. RESULTS Fifty-two patients (42% men; aged 53 ± 14 years, 36% diabetics) were evaluated. Low intake of dietary fiber was found in 90% of patients, with a median of 12.2 g per day (3.4-33.3). The group with the highest fiber intake presented lower intraperitoneal levels of IL-6, IL-8, and MCP-1. In contrast, only MCP-1 was lower in the serum of those who consumed more fiber. All the associations remained significant after adjustment for confounders with plasminogen-activator inhibitor-1 included. CONCLUSIONS Patients on PD frequently present inadequate dietary fiber intake, which appears to have an association with the inflammatory response, particularly in the intraperitoneal component. Further prospective studies, evaluating whether or not a dietetic intervention with a focus on fiber intake affects these biomarkers and clinical outcomes, are essential to determine causality and clinical relevance.

Abstract
BACKGROUND/AIMS Regular assessment of nutritional status of dialysis patients is vital for preventing malnutrition and protein energy wasting. The aim of this clinical study was to analyze dietary intake of dialysis patients and to determine if it meets their nutritional needs. METHODS Clinical study was conducted on 30 randomly selected dialysis patients in the dialysis department of the University Medical Centre Ljubljana. Nutritional interview was conducted unannounced five times over a period of three months with the 24-hour recall method. Results were analyzed with Prodi 6.6 Expert software. Body composition was measured with bioimpedance spectroscopy. RESULTS Average caloric intake of 30 patients is 14.1 ± 4.7 kcal/kg body weight per day, average protein intake is 0.61 ± 0.19 g/kg body weight per day. The average BMI (body mass index) is 27.9 ± 4.4 kg/m2, the average LTI (lean tissue index) is 12.5 ± 3.1 kg/m2, the average FTI (fat tissue index) is 14.2 ± 5.7 kg/m2 and the average phase angle is 4.2 ± 1.0. Average calorie intake and protein intake are inadequate according to the dietary recommendations for dialysis patients. Anthropometric measurements indicate sarcopenic obesity. CONCLUSION According to the aim of the study, we confirmed that caloric and protein intake of dialysis patients were inadequate according to their needs. Depending on the results of nutritional analysis and bioimpedance measurements, we have confirmed the presence of protein energy wasting among observed patients.

Abstract
Chronic kidney disease and reduced glomerular filtration rate are risk factors for the development of chronic metabolic acidosis. The prevention or correction of chronic metabolic acidosis has been found to slow progression of chronic kidney disease. Dietary composition can strongly affect acid–base balance. Major determinants of net endogenous acid production are the generation of large amounts of hydrogen ions, mostly by animal-derived protein, which is counterbalanced by the metabolism of base-producing foods like fruits and vegetables. Alkali therapy of chronic metabolic acidosis can be achieved by providing an alkali-rich diet or oral administration of alkali salts. The primary goal of dietary treatment should be to increase the proportion of fruits and vegetables and to reduce the daily protein intake to 0.8–1.0 g per kg body weight. Diet modifications should begin early, i.e., even in patients with moderate kidney impairment, because usual dietary habits of many developed societies contribute an increased proportion of acid equivalents due to the high intake of protein from animal sources.
