Ren Fail 2024; 46:2294155. [PMID: 38178375 PMCID: PMC10773634 DOI: 10.1080/0886022x.2023.2294155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 12/07/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND Inflammation plays a crucial role in occurrence of kidney injury, and specific dietary patterns can influence systemic inflammation levels. However, the relationship between dietary inflammatory potential and early-stage kidney damage remains unclear. METHOD 2,108 participants was recruited from 2001-2002 National Health and Nutrition Examination Survey (NHANES). Dietary Inflammatory Index (DII) is utilized to assess dietary inflammatory potential, calculated through a 24-h dietary recall questionnaire. Early renal injury was evaluated using urinary albumin to creatinine (UACR), cystatin C (CysC), β-2 microglobulin (β2M), and estimated glomerular filtration rate (eGFR) based on serum creatinine (eGFRs), cystatin C (eGFRc), and both Scr and CysC (eGFRs&c). Participant characteristics were analyzed, and association between DII, hypertension, and early renal injury markers was explored using multiple linear and logistic regression models. RESULTS The average age of participants was 53.9 years. DII exhibited a positive correlation with UACR (β = -0.048[0.017,0.078]), β2M (β = 0.019[0.010,0.027]), CysC (β = 0.012 [0.004,0.021]). Conversely, a negative correlation was observed between DII and eGFRc (β = -1.126[-1.554, -0.699]), eGFRs&c (β=-1.101[-1.653, -0.549]). A significant association was observed between hypertension and abnormality of early kidney damage markers. Subgroup analysis reveals that the positive correlation between DII and the occurrence of abnormal markers of early kidney damage is only observed in individuals with hypertension. Furthermore, an interaction between DII and hypertension was detected in eGFRs&c (OR:1.250[1.042, 1.499], p for interaction = 0.03). CONCLUSION Higher levels of DII may be associated with occurrence of early kidney damage. For individuals with hypertension, avoiding excessive consumption of pro-inflammatory foods may reduce the risk of renal injury.

Association between riboflavin intake and the risk of all-cause mortality of patients with chronic kidney disease: A retrospective cohort study. Medicine (Baltimore) 2024; 103:e39417. [PMID: 39331893 PMCID: PMC11441935 DOI: 10.1097/md.0000000000039417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Accepted: 08/02/2024] [Indexed: 09/29/2024] Open
Abstract
Current studies have not clarified the relationship between riboflavin intake and all-cause mortality in patients with chronic kidney disease (CKD). The aim of this study is to investigate whether there is an association between riboflavin intake and the risk of all-cause mortality in patients with CKD. This was a retrospective cohort study with data extracted from the National Health and Nutrition Examination Survey (NHANES). The study was conducted using Cox regression analysis to calculate hazard ratio (HR) and 95% confidence interval (CI) to assess the association between riboflavin intake and risk of all-cause mortality. Subgroup analyses were performed regarding gender, CKD stage, hypertension, hyperlipidemia and cardiovascular disease (CVD). A total of 3750 patients were ultimately included in the analyses. After excluding potential confounders, lower intake of riboflavin was associated with the higher risk of all-cause mortality (Q1: HR = 1.33, 95% CI: 1.05-1.69). The similar association was also found in patients at mild/moderate stage (HR = 1.32, 95% CI: 1.05-1.66), in female (HR = 1.35, 95% CI: 1.01-1.81), with hypertension (HR = 1.37, 95% CI: 1.07-1.75), CVD (HR = 1.48, 95% CI: 1.08-2.03), and dyslipidemia (HR = 1.29, 95% CI: 1.01-1.66). This study found the association between low riboflavin intake and high risk of all-cause mortality, indicating a potential beneficial role of riboflavin in CKD patients.

Chen Q, Ou L. Meta-analysis of the association between the dietary inflammatory index and risk of chronic kidney disease. Eur J Clin Nutr 2024:10.1038/s41430-024-01493-x. [PMID: 39138357 DOI: 10.1038/s41430-024-01493-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Revised: 08/01/2024] [Accepted: 08/05/2024] [Indexed: 08/15/2024]
Abstract
To explore the relationship between Dietary Inflammatory Index (DII) and chronic kidney disease (CKD) risk, we obtained 6 studies (3 prospective studies and 3 cross-sectional studies) from PubMed, CBM, Cochrane Library, and Embase, as of March 6, 2023. Our results revealed a positive link between the CKD risk and rising DII that signified a pro-inflammatory diet. With medium heterogeneity (Overall RR = 1.44, 95%CI: 1.22, 1.71; I2 = 64.7%, P = 0.015), individuals in the highest DII exposure category had a 44% greater overall risk of developing CKD than those in the lowest DII exposure category. According to risk estimations from cross-sectional studies, individuals in the highest DII exposure category had a 64% higher risk of developing CKD than those in the lowest DII exposure category, with significant heterogeneity (RR = 1.64, 95%CI: 1.18, 2.29; I2 = 70.9%, P = 0.032). The risk estimates in cohort studies revealed individuals in the highest DII exposure category had a 28% higher risk of CKD than those in the lowest DII exposure category, with a low heterogeneity (RR = 1.28, 95%CI: 1.14, 1.44; I2 = 17.2%, P = 0.015). Cross-sectional studies showed a nonlinear dose-response relationship between DII and CKD risk, while cohort studies indicated a linear dose-response relationship. Meta-regression results showed publication year, study design, and country had no significant correlation with the meta-analysis. The subgroup analysis results remained consistent. Results support the significance and importance of adopting a better anti-inflammatory diet in preventing CKD. These findings further confirm DII as a tool of the inflammatory potential of the diet to prevent and delay the onset and progression of CKD.

Higher Dietary Inflammatory Index and Systemic Immune-Inflammation Index Score are Associated With Higher Risk of Chronic Kidney Disease: Analysis of the National Health and Nutrition Examination Survey From 1999 to 2018. J Ren Nutr 2024:S1051-2276(24)00166-3. [PMID: 39074600 DOI: 10.1053/j.jrn.2024.07.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 05/16/2024] [Accepted: 07/21/2024] [Indexed: 07/31/2024] Open
Abstract
OBJECTIVE Chronic kidney disease (CKD) is characterized by a gradual decline in kidney function over time. The role of dietary inflammatory index (DII) and systemic immune-inflammation index (SII) in individuals with CKD remains uncertain. We aimed to explore the potential correlation between DII and SII with the prevalence of CKD in adult Americans. METHODS This cross-sectional study used data from the National Health and Nutrition Examination Study between 1999 and 2018. The DII was calculated based on the 24-hour dietary history interview, while the SII was calculated as the product of platelet count multiplied by neutrophil count and divided by lymphocyte count. CKD was diagnosed based on impaired glomerular filtration rate (<60 mL/min per 1.73 m2) or urinary albumin-creatinine ratio ≥30 mg/g. Multivariable logistic regression analyses and subgroup analyses were performed to examine the association between DII/SII and CKD. RESULTS In total, this study included 40,388 participants, of whom 7443 (18.4%) had CKD. The prevalence of CKD changed from 14.84% (95% confidence interval (CI): 13.20-16.48%) in 1999-2000 to 12.76% (95% CI: 11.10-14.43%) in 2017-2018. According to adjusted multivariate logistic regression models, individuals with higher DII scores had a higher likelihood of having CKD (odds ratio = 1.24; 95% CI: 1.12-1.37). Similarly, higher SII scores were associated with a higher risk of CKD (odds ratio = 1.37; 95% CI: 1.25-1.50). Subgroup analyses further demonstrated relatively stronger associations between DII/SII and CKD among individuals with other factors such as sex, age, body mass index, smoking status, drinking status, hypertension, and diabetes. CONCLUSIONS The DII and SII scores were significantly positively associated with higher risks of CKD. Anti-inflammatory diet might have the potential to prevent CKD. The SII may serve as a cost-effective and straightforward approach for detecting CKD. Further prospective longitudinal studies are needed to verify the causality.

Abstract
Background The Dietary Inflammation Index (DII) is a tool for evaluating the potential for dietary inflammation, and inflammation is a major cause of exacerbation in chronic kidney disease. Our study aimed to investigate the relationship between DII and albuminuria. Methods Data were obtained from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) after excluding pregnant, minors, and missing data of urinary albumin-creatinine ratio (ACR), estimated glomerular filtration rate (eGFR), and DII were enrolled in our study. Albuminuria was defined as ACR > 30 mg/g. DII was calculated and divided into tertiles. After fully adjusted, multivariate logistic regression analysis and subgroup analysis were performed to investigate the association between DII and albuminuria. Results A total of 22,607 participants including 2,803 (12.40%) with and 19,804 (87.60%) without albuminuria were enrolled in our study. The albuminuria increased with the increasing DII tertiles (Tertile 1: 10.81%; Tertile 2: 12.41%; Tertile 3:13.97%, P < 0.001). After fully adjusting for covariates, multivariate logistic regression showed that the higher the DII, the greater the odds of albuminuria (OR = 1.19; 95% CI, 1.00-1.41, P < 0.001). Subgroup analysis and interaction test of participants found that the positive correlation between DII and albuminuria was not significantly related to gender, age, BMI, hypertension, diabetes, and eGFR (P for interaction >0.05). Conclusion Elevated DII is associated with high odds of albuminuria. Further large-scale prospective studies are still needed to analyze the role of DII in albuminuria.

Abstract
Introduction Our objective was to explore the potential link between systemic inflammation response index (SIRI) and chronic kidney disease (CKD). Methods The data used in this study came from the National Health and Nutrition Examination Survey (NHANES), which gathers data between 1999 and 2020. CKD was diagnosed based on the low estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m2 or albuminuria (urinary albumin-to-creatinine ratio (ACR) of more than 30 mg/g). Using generalized additive models and weighted multivariable logistic regression, the independent relationships between SIRI and other inflammatory biomarkers (systemic immune-inflammation index (SII), monocyte/high-density lipoprotein ratio (MHR), neutrophil/high-density lipoprotein ratio (NHR), platelet/high-density lipoprotein ratio (PHR), and lymphocyte/high-density lipoprotein ratio (LHR)) with CKD, albuminuria, and low-eGFR were examined. Results Among the recruited 41,089 participants, males accounted for 49.77% of the total. Low-eGFR, albuminuria, and CKD were prevalent in 8.30%, 12.16%, and 17.68% of people, respectively. SIRI and CKD were shown to be positively correlated in the study (OR = 1.24; 95% CI: 1.19, 1.30). Furthermore, a nonlinear correlation was discovered between SIRI and CKD. SIRI and CKD are both positively correlated on the two sides of the breakpoint (SIRI = 2.04). Moreover, increased SIRI levels were associated with greater prevalences of low-eGFR and albuminuria (albuminuria: OR = 1.27; 95% CI: 1.21, 1.32; low-eGFR: OR = 1.11; 95% CI: 1.05, 1.18). ROC analysis demonstrated that, compared to other inflammatory indices (SII, NHR, LHR, MHR, and PHR), SIRI exhibited superior discriminative ability and accuracy in predicting CKD, albuminuria, and low-eGFR. Discussion When predicting CKD, albuminuria, and low-eGFR, SIRI may show up as a superior inflammatory biomarker when compared to other inflammatory biomarkers (SII, NHR, LHR, MHR, and PHR). American adults with elevated levels of SIRI, SII, NHR, MHR, and PHR should be attentive to the potential risks to their kidney health.

Abstract
Chronic kidney disease is prevalent within the United States likely due to dietary habits. The purpose of this study was to examine the relationship between the high-sensitivity c-reactive protein (hs-CRP) and diet quality (DQ) and their effect on the eGFR. A cross-sectional secondary data analysis study was conducted among adults (n = 6230) using NHANES 2015-2018 data. DQ was determined by the Healthy Eating Index-2015 (HEI-2015). Multivariable linear regressions were conducted based on eGFR (≥90 or <60 mL/min/1.73 m2) after adjustments for age, race/ethnicity, hypertension, diabetes mellitus, cardiovascular disease, and kidney disease awareness. All analyses were performed in SAS version 9.4 with a statistical significance of p < 0.05. Results showed that participants who had an eGFR of <60 mL/min/1.73 m2 were older and had a higher prevalence of hypertension and diabetes and had higher hs-CRP compared to participants with an eGFR ≥ 90 (p < 0.005). Of participants with an eGFR < 60, 27% reported that they were aware they had kidney disease. Regardless of the eGFR at baseline, there was a negative interaction effect on the DQ scores and hs-CRP on the eGFR (p < 0.05). Independently, for participants with an eGFR < 60, their DQ scores had a positive significant relationship on their eGFR (p = 0.03), whereas their hs-CRP had a negative significant relationship on thier eGFR (p < 0.001). For participants with an eGFR < 60, age, hypertension, and kidney disease awareness influenced this relationship (p < 0.001). Overall, low DQ and elevated hs-CRP contributed to a reduction in kidney function. Efforts to improve dietary intake and strategies to reduce inflammation and improve kidney function are necessary.

Abstract
Background A link between food-induced inflammation and common chronic diseases has been identified in studies. However, there was uncertainty about the influence of dietary inflammatory potential on the risk of chronic kidney disease (CKD) among middle-aged and older groups. Our research aimed to examine the connection between dietary inflammatory index (DII) to CKD in people aged 40 years and older. Methods This study comprised ten cycles of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. Linear associations of DII with CKD, low-eGFR, and albuminuria were examined using multiple logistic regression, whereas non-linear associations were assessed by smoothed curve fitting. Besides, we conducted subgroup analyses and interaction tests. Results Of the 23,175 middle-aged and older individuals, a total of 5,847 suffered from CKD, making up 25.23% of all participants. After adjustment for all covariates, we found that increased DII scores were positive with an increased hazard of CKD (OR = 1.08, 95% CI: 1.05, 1.10, p < 0.0001), and the same was shown between DII and low-eGFR (OR = 1.16, 95% CI: 1.13, 1.19, p < 0.0001). After further converting DII into categorical variables, the above relationship still existed. These relations were consistent in different ages, genders, BMI, whether smoking, whether suffering from hypertension, and whether suffering from diabetes, with no significant stratification differences (all P for interaction >0.05). Surprisingly, we did not find a statistically significant correlation of DII to albuminuria after complete adjustment for covariates (OR = 1.02, 95% CI: 1.00, 1.05, p = 0.0742). Even when DII was considered as a categorical variable, this relation was still not statistically significant. Furthermore, we found an association in the shape of a U between DII and low-eGFR in the fully adjusted model, with a turning point at a DII of 1.6. Conclusion Our findings indicated that middle-aged and older persons with greater levels of DII had a significantly higher risk of CKD.

Abstract
BACKGROUND AND OBJECTIVE Although the the Dietary Inflammatory Index (DII) serves to be one of the reliable indicator for hyperlipidaemia, there is still uncertainty about its relationship to prognosis in the hyperlipidaemic population. In current study, the DII levels were analyzed in relation to the mortality risk among among the hyperlipidaemic individuals with the aim of determining any prospective correlation. METHODS 14,460 subjects with hyperlipidaemia from the 10-year (2001-2010) National Health and Nutrition Examination Survey (NHANES) were chosen for this study. The endpoint event for follow-up was all-cause mortality, and subjects were tracked for up to December 31, 2019, or death, whichever occurred first. The tertiles of the DII levels were utilized for categorizing the study population into three groups. Survival curves, Cox proportional hazards regression models, restricted cubic spline (RCS), subgroup and interaction analyses, and sensitivity analyses were employed sequentially for the purpose of evaluating the association of the DII with mortality. RESULTS 3170 (21.92%) all-cause deaths were recorded during an average 148-month follow-up period. Kaplan-Meier survival curves indicated that the survival rate of participants divided into the low DII group was substantially improved compared to that of those in the higher DII group (log-rank P < 0.001). After controlling for confounders, higher levels of DII were observed to be meaningfully linked to an elevated risk of death, no matter whether DII was specified for the continuous (hazard ratio (HR): 1.06; 95% confidence interval (CI): 1.04-1.08) or the categorical variable (HR: 1.22; 95% CI: 1.11-1.33). The DII and mortality displayed a linear association, according to the RCS. Stratified and sensitivity analyses reinforced the proof that these findings were reliable. CONCLUSION Among patients with hyperlipidaemia, the risk of death was positively and linearly linked with DII levels.
