Prevalence of malnutrition and associated factors in hemodialysis patients

Relationship between altered taste and smell with malnutrition among hemodialysis patients

INTRODUCTION

Alterations in taste and smell are among the most distressing symptoms experienced by haemodialysis patients. There is limited research on the relationship between these two symptoms and malnutrition in haemodialysis patients. This study aimed to investigate alterations in taste and smell in hemodialysis patients and their relationship with malnutrition.

METHODS

This cross-sectional study was carried out with 149 hemodialysis patients at the dialysis centers of three state hospitals. The Taste and Smell Dysfunction Questionnaire was used to assess the changes in patients' taste and smell, and the Prognostic Nutritional Index (PNI), as well as the Controlling Nutritional Status (CONUT) tool, were utilized to evaluate their nutritional status.

FINDINGS

A substantial percentage (45.6%) of patients reported an altered sense of smell, and 40.2% reported an altered sense of taste. The aspect of taste that was most abnormal was bitterness (46.7%); 53.0% of the patients were at moderate risk of malnutrition by PNI score, and 14.8% were categorized as malnourished by CONUT score. Malnutrition was related to dialysis vintage: a 1-year increase in vintage was associated with an increased risk of malnutrition (OR: 1.17, 95% CI 1.02-1.32, p < 0.001). Altered taste was associated with malnutrition: one-unit increase in the standard deviation of the taste subdimension score was associated with a relative risk of malnutrition (OR: 6.89, 95% CI 1.67-28.39, p < 0.001). A one-unit increase in the standard deviation of the smell subdimension was associated with relative risk of malnutrition (OR: 1.35, 95% CI 1.10-1.64, p < 0.001).

DISCUSSION

Malnutrition was found in a significantpercentage of hemodialysis patients. Altered taste and smell and the durationof dialysis treatment were significantly associated with malnutrition scores It isrecommended that healthcare professionals regularly assess alterations in tasteand smell in hemodialysis patients, as these alterations may be associated withmalnutrition, and manage these alterations accordingly.

Screening of malnutrition with malnutrition inflammation score and geriatric nutritional risk index in hemodialysis patients

BACKGROUND AND AIMS

Screening malnutrition, which is the most common complication in hemodialysis patients, is extremely important for these patients. Malnutrition inflammation score (MIS) and geriatric nutritional risk index (GNRI) are malnutrition screening tests used in hemodialysis patients in recent years. The purposes of this study are to evaluate the nutritional status of hemodialysis patients with different screening tests and to determine the cutoff values for this disease-specific MIS and GNRI.

METHODS

The study was conducted with 194 adult patients including 98 males and 96 females whose mean age was 53.1 ± 10.96. Subjective global assessment (SGA) and MIS tests were applied, and the GNRI value was calculated for screening malnutrition. MIS and GNRI cutoff values were obtained by adopting the SGA scores as a standard and drawing a receiver operating characteristic curve. The tatistical Package for the Social Sciences-22.0 package program was used in the analysis.

RESULTS

According to SGA, 70.7% of the patients were nourished, 21.1% were mildly-moderately malnourished, and 8.2% were found to be severely malnourished. The optimal cutoff value predicted for malnutrition was 6.5 points (94.7% sensitivity and 98.5% specificity) for MIS and 86.0 points (64.9% sensitivity and 62.8% specificity) for GNRI. Based on these cutoff values, 28.9% of the patients were determined to be malnourished according to MIS and 45.4% according to GNRI.

CONCLUSION

In conclusion, screening tests are very important in the early identification of malnutrition in hemodialysis patients. This study was conducted to evaluate the malnutrition of hemodialysis patients with different screening tests. At the end of the study, the availability of MIS was found to be high in detecting malnutrition in hemodialysis patients because of its high accuracy and sensitivity of MIS. The cutoff points we identified for both MIS and GNRI are thought to facilitate the determination of malnutrition.

Nutritional status and quality of life in diabetic patients on hemodialysis: a cross-sectional study from Palestine

BACKGROUND

End-stage renal disease (ESRD) is a leading cause of death and morbidity worldwide. Malnutrition is a common problem among hemodialysis (HD) patients that negatively impacts their prognosis and is linked to an increase in morbidity and mortality in these patients, as well as a decrease in their quality of life (QOL). In this study, we aimed to evaluate the QOL and to investigate factors that can influence it, including nutritional status, as well as socio-demographic factors, among Palestinian diabetic patients on HD therapy.

METHODS

This was a cross-sectional study that occurred at a large hemodialysis center in Palestine. Malnutrition was assessed by the malnutrition-inflammation scale (MIS), and the quality of life was evaluated by using the EuroQoL five-dimensional instrument (EQ-5D). Multivariable linear regression analysis was carried out to look at the effect of multiple variables on QOL.

RESULTS

A total of 118 diabetic patients on HD were included. Of these, 66.9% were male, and 60.2% were aged 60 years or higher. Having multiple comorbid diseases (p=0.004) and having been on HD for >4 years (p=0.003) were significantly associated with a higher MIS score, whereas living alone (p=0.037) and having been on HD for >4 years (p=0.002) was significantly associated with lower EQ-5D score. We also observed a significant association between the MIS score and the EQ-5D score(r=-0.616, p<0.001). Multiple linear regression analysis demonstrated that diabetic hemodialysis patients who lived within a family household were positively correlated with the QOL score (standardized coefficient, 0.178; 95% confidence interval (CI), 0.042 to 0.372; p = 0.015), and MIS score was significantly and negatively correlated with QOL scores (standardized coefficient, -0.587; 95% CI, -0.047 to -0.028; p < 0.001).

CONCLUSIONS

We found that malnutrition was associated with a lower QOL score among diabetic patients on HD. We recommend general practitioners, dietitians, nephrologists, and nurses to make plans that pay more attention to this group of patients who show evidence of malnutrition. Patients on dialysis for ≥ 4 years, patients who live alone, and those suffering from multiple co-morbid diseases should receive special care due to their higher risk of being impacted by this problem.

Understanding Development of Malnutrition in Hemodialysis Patients: A Narrative Review

Hemodialysis (HD) majorly represents the global treatment option for patients with chronic kidney disease stage 5, and, despite advances in dialysis technology, these patients face a high risk of morbidity and mortality from malnutrition. We aimed to provide a novel view that malnutrition susceptibility in the global HD community is either or both of iatrogenic and of non-iatrogenic origins. This categorization of malnutrition origin clearly describes the role of each factor in contributing to malnutrition. Low dialysis adequacy resulting in uremia and metabolic acidosis and dialysis membranes and techniques, which incur greater amino-acid losses, are identified modifiable iatrogenic factors of malnutrition. Dietary inadequacy as per suboptimal energy and protein intakes due to poor appetite status, low diet quality, high diet monotony index, and/or psychosocial and financial barriers are modifiable non-iatrogenic factors implicated in malnutrition in these patients. These factors should be included in a comprehensive nutritional assessment for malnutrition risk. Leveraging the point of origin of malnutrition in dialysis patients is crucial for healthcare practitioners to enable personalized patient care, as well as determine country-specific malnutrition treatment strategies.

Assessment of nutritional status in the maintenance of haemodialysis patients: a cross-sectional study from Palestine

BACKGROUND

Protein-energy wasting (PEW) is a relatively prevalent problem among adult haemodialysis patients (HDP). PEW is an important determinant of morbidity and mortality in HDP, therefore it is essential for dietitians to accurately assess malnutrition (MN) in these patients. HDP appear to be more susceptible to developing MN; however, this is not well documented. Therefore this study aimed to assess the nutritional status among HDP and to establish the factors associated with MN in these patients.

METHODS

A cross-sectional survey was carried out in Nablus, northern West Bank, in the main haemodialysis (HD) centre at the An-Najah National University Hospital. MN was detected using the malnutrition-inflammation scale (MIS), which involved four major elements: the patient's related medical history, their body mass index, a physical examination and laboratory parameters.

RESULTS

A total of 174 patients (91 male) were included in the study. Patients were aged 57.7 ± 12.8 years, and the median dialysis vintage was 3 years (interquartile range 1-5 years). HDP, especially the elderly (unstandardized coefficient β, 1.728; 95% CI, 0.700 to 2.756; P = 0.001), those with multiple comorbid diseases (unstandardized coefficient β, 1.673; 95% CI, 0.556 to 2.789; P = 0.004); those taking multiple chronic medications (unstandardized coefficient β, 1.259; 95% CI, 0.197 to 2.321; P = 0.020), or those with a long dialysis vintage (unstandardized coefficient β, 1.449; 95% CI, 0.410 to 2.487; P = 0.007), were positively associated with the MIS score in a multivariable linear regression model. Furthermore, HDP living with their family were negatively associated with the MIS score (unstandardized coefficient β, - 2.545; 95% CI, - 4.738 to - 0.352; P = 0.023).

CONCLUSIONS

The MIS score results indicate that MN is prevalent among HDP. These results demonstrate some correlations between nutritional status and patient characteristics (i.e. clinical and sociodemographic factors). Therefore these findings should help to increase the awareness of healthcare providers for interventions to enhance the nutritional status of HDP, especially those who are elderly, have multiple comorbid diseases, have multiple chronic medications, have experienced a long dialysis vintage or who live alone.

Quality of Life and Nutritional Status in diabetic patients on hemodialysis

AIMS

The quality of life (QoL) of patients with diabetes and in hemodialysis is affected by their nutritional status. We aimed to determine the correlation between QoL and nutritional status of patients in hemodialysis.

METHODS

We conducted a study with people with diabetes and in hemodialysis. We used Kidney Disease and Quality of Life-Short form (KDQOL-SFTM) scale to evaluate QoL and the Subjective Global Assessment (SGA) questionnaire for nutritional evaluation.

RESULTS

The studied patients, 71.43% were over 55 years old and 81% of participants were male. The domain of QoL must impaired were cognitive function (x¯=26.35, SD = 20.81) and interaction of social quality (x¯=19.32, SD = 17.24). The characteristics that most favorably impacted QoL were dialysis equipment support (x¯=83.93, SD = 20.59) and patient satisfaction (x¯=86.51, SD = 17.17). The undernourished patients were 56.6% (n = 14). There was a strong lineal relationship between the Physical and Mental Health Composite and nutritional status, Spearman rank (rho = 0.935, p = <0.001), (rho=0.926, p = <0.001) respectively.

CONCLUSION

There is a strong relationship between QoL and nutritional status, ensuring that a good nutritional status could positively influence QoL.

Malnutrition and cardiovascular risk in haemodialysis patients with chronic kidney disease

ABSTRACT Objective To verify the association between nutritional status and traditional and non-traditional cardiovascular risk factors in haemodialysis patients. Methods A cross-sectional study with 132 patients over 18 years of age on haemodialysis to evaluate nutritional status through Subjective Global Assessment. Information on traditional and non-traditional cardiovascular disease risk factors were obtained using a structured questionnaire; the Framingham score was also used to assess cardiovascular risk. Data analysis was performed using the Chi-square Test or Fischer Exact Test and a Log-binomial Regression Model. Results Malnutrition affected 31.1% of patients. Among them, a higher percentage of smokers (p=0.016), former smokers (p=0.034) and diabetes Mellitus patients (p=0.001) were detected. Malnutrition was found to be 4.53 times more prevalent in diabetic individuals (95%CI: 1.99-10.27) and 2.26 times more prevalent among former smokers (95%CI: 1.04-4.95). Malnourished individuals exhibited a 4.03 times prevalence of moderate to severe cardiovascular risk. Conclusion A high prevalence of malnutrition and of other risk factors for cardiovascular disease were observed. Such factors included diabetes Mellitus, smoking and former smoker conditions and were associated with malnutrition. Inaddition, it was found that malnourished individuals were more likely to develop cardiovascular disease within 10 years.
