    Post-transplantation Anemia Predicts Cardiovascular Morbidity and Poor Graft Function in Kidney Transplant Recipients
    (2015) Demirci, B. Gurlek; Sezer, S.; Sayin, C. B.; Tulal, E.; Uyar, M. E.; Acar, F. N. Ozdemir; Haberal, M.; 0000-0002-3462-7632; 0000-0002-5682-0943; 26036548; IAO-2608-2023; AAJ-8097-2021; AAK-1697-2021
    Objective. We aimed to investigate whether low post-transplantation-period hemoglobin levels are predictive of cardiovascular morbidity in terms of left ventricular (LV) hypertrophy and vascular stiffness and to determine the contributing factors of post-transplantation anemia in kidney transplant (KT) recipients. Methods. One hundred fifty (mean age, 38.9 +/- 10.8 y; 113 male) KT recipients with functioning grafts were enrolled in the study. All subjects underwent clinical and laboratory evaluations (24-hour urinary protein loss, complete blood count) and transthoracic echocardiography to assess LV systolic function. Arterial stiffness was measured by means of carotid-femoral pulse-wave velocity (PWV). Mean hemoglobin levels were analyzed at the 1st, 6th, 12th, and 24th months after transplantation. Patients were divided into 2 groups according to presence of anemia: patients with anemia (group 1; n = 120) and normal (group 2; n = 30). Results. PWV values (6.8 +/- 1.9 m/s vs 6.4 +/- 1.1 m/s in groups 1 and 2, respectively; P = .002) and LV mass index (LVMI; 252.1 +/- 93.7 g/m(2) vs 161.2 +/- 38.5 g/m(2) groups 1 and 2, respectively; P = .001) were significantly higher in group 1. Estimated glomerular filtration rate and (64 +/- 28.5 m/min vs 77.8 +/- 30 m/min in groups 1 and 2, respectively; P = .001) LV systolic function (57.2 +/- 5.8% vs 77.8 +/- 30% in groups 1 and 2, respectively; P < .005) were significantly lower in group 1. In regression analysis, LV systolic function and LVMI were predictors of post-transplantation hemoglobin levels. Conclusions. Post-transplantation anemia contributes to cardiovascular morbidity by deteriorating LV function and increasing PWV and is therefore associated with poor prognosis for graft survival. Early correction of post-transplantation anemia, especially with the use of erythropoietin, may be beneficial for both graft and recipient survivals.

    Plant-based diets to manage the risks and complications of chronic kidney disease
    (2020) Carrero, Juan J.; Gonzalez-Ortiz, Ailema; Avesani, Carla M.; Bakker, Stephan J. L.; Bellizzi, Vincenzo; Chauveau, Philippe; Clase, Catherine M.; Cupisti, Adamasco; Espinosa-Cuevas, Angeles; Molina, Pablo; Moreau, Karine; Piccoli, Giorgina B.; Post, Adrian; Sezer, Siren; Fouque, Denis; 32528189
    Traditional dietary recommendations for patients with chronic kidney disease (CKD) focus on the quantity of nutrients consumed. Without appropriate dietary counselling, these restrictions can result in a low intake of fruits and vegetables and a lack of diversity in the diet. Plant nutrients and plant-based diets could have beneficial effects in patients with CKD: increased fibre intake shifts the gut microbiota towards reduced production of uraemic toxins; plant fats, particularly olive oil, have anti-atherogenic effects; plant anions might mitigate metabolic acidosis and slow CKD progression; and as plant phosphorus has a lower bioavailability than animal phosphorus, plant-based diets might enable better control of hyperphosphataemia. Current evidence suggests that promoting the adoption of plant-based diets has few risks but potential benefits for the primary prevention of CKD, as well as for delaying progression in patients with CKD G3-5. These diets might also help to manage and prevent some of the symptoms and metabolic complications of CKD. We suggest that restriction of plant foods as a strategy to prevent hyperkalaemia or undernutrition should be individualized to avoid depriving patients with CKD of these potential beneficial effects of plant-based diets. However, research is needed to address knowledge gaps, particularly regarding the relevance and extent of diet-induced hyperkalaemia in patients undergoing dialysis. Emerging evidence suggests that plant-based diets could help to prevent chronic kidney disease (CKD), manage its symptoms and metabolic complications and delay disease progression. Here, the authors discuss the potential risks and benefits of these diets in patients with CKD, as well as implementation strategies and knowledge gaps.
