Unlabelled: This study explored the associations between triglyceride glucose (TyG), TyG with body mass index (TyG-BMI), triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-C) ratio, and metabolic score for insulin resistance (METS-IR) and the effects of dietary acid-base load in patients with chronic kidney disease (CKD).
Methods: A total of 288 patients with CKD were included in this study. Four non-insulin-based insulin resistance (IR) markers were used to assess IR levels in patients with CKD; dietary intake - 24-h dietary recall; and diet-based acidity - potential renal acid load (PRAL), net endogenous acid production (NEAP), and dietary acid load (DAL). Multiple linear regression analysis correlated dietary acid-base load and non-insulin-based IR markers.
Results: Spearman's correlation indicated DAL was significantly associated with TyG-BMI (r = 0.251, P < 0.001) and METS-IR (r = 0.274, P < 0.001), but weakly correlated with the TG/HDL-C ratio (r = 0.14, P = 0.018). After adjusting for sex, age, energy, hypertension (HTN), diabetes, and estimated glomerular filtration rate, multiple linear regression analysis showed that DAL was associated with TyG-BMI (β = 0.336; P = 0.008) and METS-IR (β = 0.091; P = 0.007).
Conclusions: Patients with the highest DAL scores had the highest TyG-BMI, TyG, TG/HDL-C ratio, and METS-IR. After adjusting for confounders, there was a significant positive association between DAL and TyG-BMI and METS-IR.

: Increasing evidence indicates that a vegetarian diet may provide renal protection and improve metabolic health in patients with chronic kidney disease (CKD). However, transitioning from an omnivorous to a vegetarian diet can be challenging. A more practical alternative could be to increase the consumption of plant protein.

Metabolic acidosis is a common complication of chronic kidney disease (CKD). The kidneys play a crucial role in acid-base balance, maintaining pH within the normal range (isohydria) by following mechanisms: bicarbonate reabsorption, ammogenesis, and titratable acidity. The anion gap describes the amount of unmeasured anions and is classically evaluated as the difference between the major cation (sodium) and the sum of the two major anions (chloride and bicarbonate).

We have previously reported that adenine at high doses interferes with the vasopressin signaling pathway, causes massive diuresis and volume depletion, and ultimately leads to renal failure. In the present study, we examined the effects of adenine on renal salt and water handling in a time course and dose-response study in rats housed in metabolic cages and fed control or adenine-containing diet at 1500, 2000, 2500 mg/kg and euthanized after 1, 3, and 7 weeks. Adenine at 2000 and 2500 mg/kg caused early and significant polyuria, polydipsia, and decreased urine osmolality in a dose-dependent manner without significantly affecting food intake, blood volume, blood electrolyte levels, or acid-base composition.

Chronic kidney disease (CKD) management requires a comprehensive and multidisciplinary approach to optimize clinical outcomes. This review systematically outlines essential components of CKD care from A to Z, offering evidence-based guidance to enhance patient management. Anemia treatment emphasizes iron supplementation, erythropoiesis-stimulating agents, and novel hypoxia-inducible factor prolyl hydroxylase inhibitors.

Purpose: A higher diet-dependent acid-base load has been associated with low grade inflammation and selected medical conditions. No study has examined the association between diet-dependent acid-base load and progression or inflammatory activity measures in persons with multiple sclerosis (MS).
Methods: A prospective cohort, aged 18-59 years at study entry, was followed annually for ten years as part of the AusLong Study.
