Although phosphorus is an essential element for life, it is not found in nature in its native state but rather combined in the form of inorganic phosphates (PO), with tightly regulated plasma levels that are associated with deleterious effects and mortality when these are out of bounds. The growing interest in the accumulation of PO in human pathophysiology originated in its attributed role in the pathogenesis of secondary hyperparathyroidism (SHPT) in chronic kidney disease. In this article, we review the mechanisms by which this effect was justified and we commemorate the important contribution of a Spanish group led by Dr.

Hyperkalaemia (HK) is one of the most common electrolyte disorders and a frequent reason for nephrological consultations. High serum potassium (K) levels are associated with elevated morbidity and mortality, mainly due to life-threatening arrhythmias. In the majority of cases, HK is associated with chronic kidney disease (CKD), or with the use of renin-angiotensin-aldosterone system inhibitors (RAASis) and/or mineral corticoid antagonists (MRAs).

Objectives: To evaluate the effect of haemodialysis on doravirine concentrations in people living with HIV (PLWH) undergoing routine haemodialysis.

Methods: An exploratory clinical trial that included PLWH undergoing intermittent haemodialysis was undertaken. After enrolment (day 1), doravirine 100 mg once daily was added to stable combined ART for 5 days.

Purpose: It has been proved that the gut microbiome is altered in patients with chronic kidney disease. This contributes to chronic inflammation and increases cardiovascular risk and mortality, especially in those undergoing hemodialysis. Phosphate binders may potentially induce changes in their microbiome.

Article Synopsis
  • - The study aims to compare the clinical presentation and inflammatory biomarkers in kidney transplant patients with COVID-19 pneumonia versus those with pneumonia from other causes.
  • - Results showed that COVID-19 patients had fewer neutrophils and higher ferritin levels, while non-COVID cases had elevated d-dimer and interleukin-6 levels.
  • - The findings suggest distinct inflammatory profiles for COVID-19 pneumonia in kidney transplant patients, indicating a need for further research to enhance understanding and treatment.

Aims: Systolic pulmonary artery pressure (SPAP) and right heart adaptation in relation to pre-existing preload are often disregarded. To determine volume-related changes in the pulmonary-right ventricle (RV) unit and the preload dependence of its components, we analysed pulmonary haemodynamics and right ventricular performance, taking advantage of the plasma volume removal associated to haemodialysis (HD).

Methods And Results: Fifty-three stable patients on chronic HD with LVEF > 50% and without heart failure were recruited (mean age 63.

Introduction: Labeling a patient as "frail" may be useful in assessing the prognosis and therapeutic approach.

Objective: The aim of the study is to define a pattern of frailty among our dialysis population, to analyse the incidence and clinical evolution of these patients.

Materials And Methods: We analysed a total of 320 patients with stage V chronic kidney disease (CKD) who were on hemodialysis between September 2014 and September 2015.

Data on dolutegravir removal by hemodialysis are lacking. To study this, we measured dolutegravir plasma concentrations in samples of blood entering and leaving the dialyzer and of the resulting dialysate from 5 HIV-infected patients with end-stage renal disease. The median dolutegravir hemodialysis extraction ratio was 7%.

Background: IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide, leading to renal failure in 15% to 40% of cases. IgAN is diagnosed by renal biopsy, an invasive method that is not risk-free. We used blood and urine peptide profiles as a noninvasive method of linking IgAN-associated changes with histological lesions by Oxford classification.
