The aim of this study was to evaluate adherence to Mediterranean diet (MeDi) and possible correlation of MeDi adherence and nutritional status parameters in Dalmatian kidney transplant recipients (KTRs). One hundred and sixteen KTRs were included in this study. Data about Mediterranean Diet Serving Score (MDSS), body mass composition, anthropometric parameters, clinical and laboratory parameters were collected for each study participant. The results showed 25% adherence to the MeDi in Dalmatian KTRs. MDSS showed association with higher serum albumin and phosphorus level and higher skeletal muscle mass. Also, significant association between diabetic status and MDSS was found. Adherence to olive oil intake suggested by the MeDi showed significant association with lower level of triglycerides and adherence to nuts suggestions was associated with lower level of fat mass. Following MeDi recommendations for consumption of other foods (cereals, potato, eggs, vegetables, fruits and dairy) w...

Considering the high prevalence of metabolic syndrome and its association with cardiovascular mortality, we prospectively evaluated the role of diet in the incidence of metabolic syndrome in renal transplant recipients. Our prospective cohort of 160 adult renal allograft recipients was followed for 1 year and had no existing metabolic syndrome or diabetes mellitus. Routine dietary intakes were assessed with food-frequency questionnaires, and metabolic syndrome was defined according to the Adult Treatment Panel III guidelines. We identified 3 major patterns by factor analysis, consisting of those recipients predominantly consuming fats and sugars, those predominantly consuming whole grain, and the Mediterranean diet. When analyzed by multivariable logistic regression and after controlling for potential confounders, subjects in the highest tertile of scores for the Mediterranean diet had a significantly lower odds of metabolic syndrome than those in the lowest tertile. Subjects in the highest tertile of scores for consuming fats and sugars had significantly greater odds of metabolic syndrome compared with those in the lowest tertile. Our study shows that the Mediterranean dietary pattern is associated with a reduced risk of metabolic syndrome in renal transplant recipients.

The incidence of new-onset diabetes after transplantation (NODAT) and premature mortality is high in renal transplant recipients (RTR). We hypothesized that a Mediterranean Style diet protects against NODAT and premature mortality in RTR. A prospective cohort study of adult RTR with a functioning graft for >1 year. Dietary intake was assessed with a 177-item validated food frequency questionnaire. Patients were divided based on a 9-point Mediterranean Style Diet Score (MDS): low MDS (0-4 points) versus high MDS (5-9 points). A total of 468 RTR were eligible for analyses. Logistic multivariable regression analyses were used to study the association of MDS with NODAT and Cox multivariable regression models for the association with all-cause mortality. Mean±SD age was 51.3±13.2 years and 56.6% were men. About 50% of the patients had a high MDS. During median follow-up of 4.0 (IQR, 0.4-5.4) years, 22 (5%) RTR developed NODAT and 50 (11%) died. High MDS was significantly associated wi...

Background: The aim of this study was to examine the relationship between diet quality and weight gain in kidney transplant recipients from pretransplant baseline through posttransplant at 3 months and 1 year. Methods: Data from a prospective, observational cohort study of kidney transplant patients (n = 26) were analyzed. Participants were adult (aged 18-65 years), living donor kidney transplant recipients who were participating in a prospective body composition study. Body weight, body mass index, dietary intake, and Healthy Eating Index scores were used to assess changes in weight, nutrient intake, and diet quality. Findings: At the time of kidney transplantation, 42% (n = 11) were obese and 27% (n = 7) were overweight. Weight significantly increased from transplantation to 12 months (mean [SD]: 83 [18] kg and 90 [18] kg, respectively; mean change 8.4%, P = .002). At 12 months posttransplant, dietary fat intake significantly increased ( P = .033). Body weight was strongly correla...

Background. In these last years, several traditional risk factors for cardiovascular disease, like obesity, dyslipidaemia, hypertension and post-transplant diabetes mellitus have been also identified as important nonimmunological risk factors leading to the development of chronic allograft nephropathy, the first cause of graft loss in transplanted patients. The aim of the present study was to determine the effects of a 12-month dietary regimen on the nutritional status and metabolic outcome of renal transplant recipients in the first post-transplant year. Methods. Forty-six cadaver-donor renal transplant recipients (mean age 40.8 AE 10.1-years), enrolled during the first post-transplant year (4.8 AE 3.3 months) and followed prospectively for a 12 month period. Biochemical and nutritional markers, anthropometric measurements, body composition (by conventional bioelectrical impedance analysis) and dietary records (using a detailed food-frequency questionnaire) at baseline and after 12 months. Results. Compliance to the diet was related to sex (male better than female) and was associated with weight loss primarily due to a decrease in fat mass, with decrease in total cholesterol and glucose plasma levels and with a concomitant rise in serum albumin. Conclusion. After renal transplantation, health benefits of proper metabolic balance that include reduced body fat, weight loss, lower cholesterol and triglycerides levels and an improvement, fasting glucose levels can be obtained when dietary intervention occurred.

Low fruit and vegetable consumption is associated with poor outcomes after renal transplantation. Insufficient fruit and vegetable consumption is reported in the majority of renal transplant recipients (RTR). The aim of this study was to identify barriers and facilitators of fruit and vegetable consumption after renal transplantation and explore if certain barriers and facilitators were transplant-related. After purposive sampling, RTR (n = 19), their family members (n = 15) and healthcare professionals (n = 5) from a Dutch transplant center participated in seven focus group discussions (three each for RTR and family members, one with healthcare professionals). Transcripts were analyzed using social cognitive theory as conceptual framework and content analysis was used for identification of themes. Transplant-related barriers and facilitators were described separately. In categorizing barriers and facilitators, four transplant-related themes were identified: transition in diet (acco...
Dietary Nutrients and Cardiovascular Risk Factors among Renal Transplant Recipients
International Journal of Environmental Research and Public Health, 2021
Cardiovascular disease (CVD) is the leading cause of mortality in post-renal transplant recipients (RTRs). Adequate nutrient intake is a protective factor for CVD. We examined the associations of macronutrients and micronutrients with traditional and nontraditional CVD risk factors. Conducted from September 2016 to June 2018, this cross-sectional study included 106 RTRs aged ≥18 years with a functioning allograft. Dietary intake data from 3-day dietary records were collected. Nutrient intake adequacy was defined using various instruments, including the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines. CVD risk factors were defined according to the K/DOQI guidelines. Bivariate and multivariate logistic regression models were used to analyze the associations. CVD risk was present in all patients; the lowest proportions of adequate intake were 2.8% for dietary fiber and 0.9% for calcium. Adequate nutrient intake was associated with a lower likel...
