Background: Many animal studies suggested that the uremic toxin indoxyl sulphate can add to renal damage following induced nephrotoxicity and this effect has not been proved in patients with such complication.
Methods: This is a prospective, case-control, and an observational study conducted on 74 critically ill patients with acute nephrotoxicity. It was designed to measure serum levels of indoxyl sulphate on the day of enrollment and over the course of their illness using high performance liquid chromatography (HPLC-UV) and to test the correlation between these levels and patient's demographics, clinical characteristics, physiological variables, and their outcomes.
Results: Critically ill patients with acute nephrotoxicity had significantly higher total (IS) and free (IS) indoxyl sulphate than healthy controls and significantly lower than patients with end-stage renal disease (ESRD). Although, no correlation was found between IS or IS and mortality, among survivors, IS, IS, creatinine and eGFR were independently associated with no renal recovery.
Conclusion: Serum indoxyl sulphate levels were elevated in critically ill patients with acute nephrotoxicity. There is an association between high levels of indoxyl sulphate and no renal-recovery outcome among survivors of acute nephrotoxicity. Early removal of indoxyl sulphate from patients' blood may improve their outcomes.

The vagus nerve is proposed to enable communication between the gut microbiome and the brain, but activity-based evidence is lacking. We find that mice reared germ-free exhibit decreased vagal tone relative to colonized controls, which is reversed via microbiota restoration. Perfusing antibiotics into the small intestines of conventional mice, but not germ-free mice, acutely decreases vagal activity which is restored upon re-perfusion with intestinal filtrates from conventional, but not germ-free, mice.

Object: Patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) have a high risk of serious infection, in particular severe pneumonia. This study aimed to investigate the transcriptional landscape, lower respiratory tract (LRT) microbiome and metabolomic profiles in the lung of RA-ILD patients with pneumonia.
Method: A total of 10 RA-ILD with pneumonia were enrolled in this study.

Epidemiological studies suggest an increased risk of colorectal cancer (CRC) aggravation in patients with chronic kidney disease (CKD). Our previous study demonstrated that indoxyl sulfate, a uremic toxin whose concentration increases with CKD progression, exacerbates CRC through activation of the AhR and Akt pathways. Consequently, indoxyl sulfate has been proposed to be a significant link between CKD progression and CRC aggravation.

The dialysis membrane based on a hydrophilic polymer (Hydrolink NV) was designed to enhance the movement of adsorbed water at the blood-membrane interface, aiming to achieve antithrombogenic and antifouling effects. This study aimed to assess the performance and albumin loss of the Hydrolink NV dialyzer in hemodialysis (HD) and post-dilution hemodiafiltration (HDF) with different infusion flows (Qis) and compare it with the hydrophilic FX CorAL dialyzer in post-dilution HDF. A prospective study was carried out in 20 patients.

Introduction: Olfactory dysfunction is prevalent among individuals with chronic kidney disease (CKD), with prevalence escalating alongside disease severity. The uremic toxin we observed in this study is Indoxyl sulfate (IS), a potent uremic toxin that markedly accumulates in the plasma of patients with chronic insufficiency. Olfactory damage may occur in the setting of neuronal damage due to renal failure.
