Introduction: Severe pneumonia is a crucial issue in the development of acute kidney injury (AKI). This study evaluated the efficacy of early goal-directed renal replacement therapy (GDRRT) for the treatment of severe pneumonia-associated AKI.

Methods: In this real-world retrospective cohort study, we recruited 180 patients with severe pneumonia who were hospitalized and received GDRRT in a third-class general hospital in East China between January 1, 2017, and December 31, 2021.

Background: The gut microbiota plays a crucial role in regulating host metabolism and producing uremic toxins in patients with end-stage renal disease (ESRD). Our objective is to advance toward a holistic understanding of the gut ecosystem and its functional capacity in such patients, which is still lacking.

Results: Herein, we explore the gut microbiome of 378 hemodialytic ESRD patients and 290 healthy volunteers from two independent cohorts via deep metagenomic sequencing and metagenome-assembled-genome-based characterization of their feces.

Aims: To investigate the immunological characteristics of hemodialysis (HD) patients with end-stage renal disease (ESRD) of various ages, and the impact of age-related immune alterations on these patients, with a focus on peripheral T cells.

Methods: From September 2016 to September 2019, HD patients were enrolled and followed prospectively for 3 years. Patients were divided into three groups based on their ages: < 45, 45 to 64, and ≥ 65.

Background: Crescent formation indicates severe glomerular pathology, and hypothyroidism usually predicts poor prognosis for severe diseases. However, the relationship between thyroid function and the progression of chronic kidney disease (CKD) is unclear. This study analysed the prognostic predictive value of the serum free triiodothyronine (FT3) to free thyroxine (FT4) ratio and its correlation with renal function in patients with CKD with crescent formation.

Aims: Prostaglandin E (PGE2) is involved in the development of cardiac hypertrophy. However, whether PGE2 regulates the chronic kidney disease-associated cardiac hypertrophy and the tentative mechanism remains to be elucidated.

Methods And Results: We explored the effect of PGE2 receptor inhibitors on cardiac hypertrophy in vitro and in a 5/6 nephrectomy (5/6NT) rat model using quantitative reverse transcription polymerase chain reaction, western blotting, enzyme-linked immunosorbent assay, immunohistochemical staining, and immunofluorescence staining assays.

The purpose of this study was to explore the differences between exhausted CD8 T cells in hepatocellular carcinoma (HCC) patients with and without uremia. We enrolled 45 uremic patients who were recently diagnosed with HCC into the HCC + uremia cohort and similar patients with HCC but without uremia into the HCC-only cohort. Lymphocytes were obtained from the two cohorts, and exhausted CD8 T cells, comprising PD-1CD8, TIM-3CD8, and LAG-3CD8 T cells, were sorted and expanded in vitro.

Background: Information concerning the cancer issue in Chinese patients on hemodialysis (HD) was lacking. Thus, we examined data from our dialysis registry to investigate the incidence of cancer, identify the possible factors, and explore outcomes after cancer diagnosis in patients on chronic HD.

Methods: A retrospective cohort study of 639 new-onset end-stage renal disease patients who started HD therapy during the period from July 1999 to December 2017 was retrieved from the database in our dialysis center.

Background: Patients on chronic hemodialysis (HD) have an increased incidence of malignancy due to decreased immunity. Soluble interleukin-2 receptor (sIL-2R), as an immunomodulator, seemed to have an effect in the process of malignancy. In this study, we aimed to evaluate the clinical significance of increased sIL-2R in the course of malignancy among HD patients.

Purpose: Cerebrovascular complications, including ischemic stroke, account for poor outcomes in patients on hemodialysis. T cell responses may be involved in the pathogenesis of ischemic stroke. We aimed to evaluate the role of naïve T cells in development of ischemic stroke in patients on hemodialysis.

Chronic kidney disease (CKD) is an increasingly recognized disease with high global incidence and mortality. Yet, the existing diagnostic tools are not sufficient enough to predict prognosis of CKD and CKD comorbidities. Indoxyl sulfate, a typical uremic toxin, is of great importance in the development of CKD with its nephrotoxicity, cardiovascular toxicity, and bone toxicity.

Aims: To examine the association between red blood cell distribution width (RDW) and mortality in hemodialysis (HD) patients.

Methods: Three hundred fifty six patients on HD for >3 months were enrolled and followed for 2 years. Patients were divided into 2 groups according to the median RDW value.

The aim of this study is to investigate the effects of endogenous vasoactive substances on the occurrence of intradialytic hypertension (IDH) in patients during maintenance hemodialysis. Thirty-four maintenance hemodialysis patients were enrolled in this trial, and 17 of them were diagnosed with IDH (defined as an increase in blood pressure of at least 10 mmHg during or immediately after a hemodialysis session), while 17 age-matched and sex-matched controls without IDH were selected for a retrospective comparison. We collected patients' blood samples before and after a dialysis session and measured the plasma levels of N-terminal fragment brain natriuretic peptide, renin, angiotensin-II, aldosterone (ALD), angiotensin-converting enzyme (ACE), endothelin-1 (ET-1), nitric oxide (NO), norepinephrine (NOR), and adrenomedullin.

In a 53-year-old woman, Sagliker syndrome developed during 22 years of treatment with intermittent hemodialysis as a result of severe secondary hyperparathyroidism (SHPT) complicating end-stage renal disease. She failed medical managements and lost her renal graft just after the kidney transplantation due to acute rejection. Although surgical parathyroidectomy was effective, the parathyroid hormone level became extremely high again due to recurrent hyperparathyroidism.

In the current study, we measured urinary angiotensinogen (AGT) through enzyme-linked immunoadsordent assay (ELISA) and analyzed its correlation with intrarenal renin-angiotensin system (RAS) activity in 128 chronic kidney disease (CKD) patients. Urinary and plasma renin activity, AGT, angiotensin II (Ang II) and aldosterone levels were also measured by radioimmunoassay (RIA) or ELISA in these participants. Further, the expression level of intrarenal renin, AGT, Ang II and Ang II receptors were examined by immunohistochemistry staining (IHCS) in 72 CKD patients.

Background: Residual renal function (RRF) recently has been confirmed to be a significant predictor of morbidity and mortality in hemodialysis (HD) patients. As RRF is not exactly the same with 24-h residual urine volume, the aim of our study is to evaluate the association of residual urine volume with acute ischemic stroke (AIS) among HD patients.

Methods: 282 patients starting chronic HD in our center during January 2005 and December 2008 were enrolled.
