BACKGROUND: The existing data support the Chalder Fatigue Questionnaire (CFQ-11) as a valid instrument to assess fatigue in maintenance hemodialysis (MHD) patients. The objective of this work was to investigate whether self-reported fatigue can serve as an independent prognostic indicator for mortality in MHD patients. METHODS: The data are from 233 adult patients enrolled in the cohort "The Prospective Study of the Prognosis of Chronic Hemodialysis Patients" (PROHEMO) developed in Salvador, BA, Brazil...

BACKGROUND: Interstitial fibrosis and tubular atrophy (IFTA) are common findings on biopsy in chronic kidney disease (CKD) and strongly predictive of kidney failure. IFTA is poorly correlated with estimated glomerular filtration rate (eGFR) and albuminuria, the most common metrics of kidney disease. Thus, IFTA is prognostically important, yet its presence and severity are invisible to the clinician except when kidney biopsies are obtained. OBJECTIVES: To investigate 1) the cross-sectional association between urine uromodulin (uUMOD) and IFTA, and 2) to determine whether uUMOD levels were associated with diuretic response after a furosemide stress test...

INTRODUCTION: C-reactive protein-to-albumin ratio (CAR) is a prognostic marker in various diseases that represents patients' inflammation and nutritional status. Here, we aimed to investigate the prognostic value of CAR in critically ill patients with severe acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT). METHODS: We retrospectively collected data from eight tertiary hospitals in Korea from 2006-2021. The patients were divided into quartiles according to CAR levels at the time of CRRT initiation...

INTRODUCTION: Atypical hemolytic uremic syndrome (aHUS) is a thrombotic microangiopathy (TMA) disease entity primarily attributed to genetic or acquired abnormalities in the alternative complement pathway. TMA can manifest in kidney transplant (KT) recipients owing to various factors, resulting in diverse clinical presentations. Given its adverse effects on allograft function and patient prognosis, genetic diagnostic approaches for aHUS are essential. Although rarely associated with diffuse alveolar hemorrhage, only a few mild cases have been reported to date...

INTRODUCTION: Suppressor of cytokine signaling 3 (SOCS3) is highly expressed in mice with renal ischemia/reperfusion (RI/R) injury and has the potential to regulate mitophagy. On this basis, this study further investigates the possible mechanism via which SOCS3 affects RI/R by regulating mitophagy. METHOD: After establishing a RI/R injury mouse model and a hypoxia/reoxygenation (H/R) cell model, the effects of silenced SOCS3 on injury and mitophagy in the above models were analyzed by ELISA, qRT-PCR, Western blot, pathological sections, CCK-8 assay, flow cytometry and JC-1 assay...

INTRODUCTION: Primary membranoproliferative glomerulonephritis (MPGN) is a rare kidney disease with poor prognosis and no specific therapies. The disease heterogeneity and the difficulty of performing repeated kidney biopsies poses big challenges. This study investigates the correlation between non-contrast enhanced magnetic resonance imaging (MRI) and histologic and clinical findings in patients with primary MPGN. METHODS: Patients with primary MPGN underwent baseline and 1-year kidney MRI in addition to biopsy and laboratory testing as part of a prospective MRI subproject of a clinical trial (ClinicalTrials...

Introduction The aim of this study is to evaluate the frequency and causes of hospitalizations in the post-transplant period of children, to investigate the risk factors, and evaluate the relationship between hospitalizations and renal prognosis in the long term. Methods We retrospectively reviewed the files of pediatric renal transplant patients, followed at least 6 months after kidney transplantation, in our center. Clinical information including age at transplantation, gender, primary disease, donor type, immuno-suppressive medication, hospitalization dates and indications (infections and non-infectious) during follow-up period and graft outcomes were recorded...

INTRODUCTION: MicroRNAs, short noncoding RNAs, are involved in the modulation of gene expression, mainly by inhibiting the translation of mRNAs. Under physiological conditions, miRNAs are involved in viral infections and immune responses, among others; aberrant miRNA expression has been associated with kidney transplant pathologies, but a comprehensive comparison of later, particularly in tissue sections, is still pending. METHODS: We used the genome-wide screening of miRNAs to identify those potentially involved in the disease processes after kidney transplantation...

BACKGROUND: Beta cells play a key role in the pathophysiology of diabetes, since their functional adaptation is able to maintain euglycemia in the face of insulin resistance, and beta cell decompensation or dysfunction is a necessary condition for full-blown type 2 diabetes (T2D). The mechanisms behind compensation and decompensation are incompletely understood, especially for human beta cells, and even less is known about influences of chronic kidney disease (CKD) or immunosupressive therapy after transplantation on these processes and the development of post-transplant diabetes...

Chronic kidney disease (CKD) is an increasingly prevalent disease that affects approximately 10-12% of the global population. Therefore, it is considered a public health priority. Persistent and systemic low-grade chronic inflammation (CI) is an important part of the poor prognosis in CKD, especially for patients with advanced disease. For example, CI worsens anemia and promotes atherosclerosis. Therefore, CI deserves our attention. The formation of CI in CKD involves many aspects. Among them, the decline in the glomerular filtration rate leads to the influence of substances or inflammatory cytokines that should be cleared in time...

BACKGROUND: Penehyclidine hydrochloride (PHC) has been shown to be effective in the treatment of rhabdomyolysis (RM)-induced acute kidney injury (AKI). Our research sought to investigate the pharmacological effects and mechanisms of PHC on RM-induced AKI. METHODS: RM-induced AKI models were established by FeG treatment and glycerol injection. Cell viability was analyzed by CCK-8 assay. ROS levels were examined by Flow cytometry. The LDH, Fe2+, MPO, MDA and GSH levels were measured using the corresponding kits...

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors exert a kidney protective effect in patients with diabetic kidney disease. Several mechanisms have been proposed but why precisely SGLT2 inhibition has a kidney protective effect is incompletely understood. Clinical trials using SGLT2 inhibitors have found them to induce a rapid weight loss likely due to loss of sodium and subsequently fluid. While SGLT2 inhibitors are reported to increase hematocrit, it remains unknown whether the natriuretic and aquaretic effect reduces patient's blood volume and whether this could partly explain its kidney protective effects...

INTRODUCTION: Blood coagulation is associated with glomerulonephritis (GN) pathophysiology. Using whole-blood-based rotational thromboelastometry, we recently reported that the degree of hypercoagulability in pediatric patients with immunoglobulin A nephropathy (IgAN), a GN, might be associated with pathological severity. To further clarify the coagulation status of mesangial proliferative glomerulonephritis (MesPGN), we assessed the platelet thrombus formation (PTF) under high-shear flow using a microchip-based flow chamber system (T-TAS®)...

Continuous renal replacement therapy (CRRT) is frequently used for fluid management of critically ill patients with acute or chronic kidney failure. There is significant practice variation worldwide in fluid management during CRRT. Multiple clinical studies have suggested that both the magnitude and duration of fluid overload are associated with morbidity and mortality in critically ill patients. Therefore, timely and effective fluid management with CRRT is paramount in managing critically ill patients with fluid overload...

NCAM1 is a recently identified new antigen of membranous nephropathy (MN) mostly secondary to systemic lupus erythematosus (SLE) with a low positive rate of 6.6%, and its corresponding antibody was detected in patients' sera. Here, we reported a case of NCAM1-positive lupus nephritis (class Ⅴ+Ⅲ) developed from MN. The patient was refractory to multiple immunosuppressive regimens, but achieved remission after the application of rituximab as an add-on therapy and showed a reduction of anti-NCAM1 antibody and proteinuria...
