Research progress on the mechanism of hyperuricemic nephropathy based on multi-omics technique: A review.

Hyperuricemic nephropathy is a metabolic disease in which renal uric acid deposition and excretion are impaired due to elevated levels of uric acid in the blood, leading to impaired renal tubule function and chronic renal disease. Hyperuricemic nephropathy is one of the important complications of hyperuricemia, which seriously affects the quality of life and prognosis of patients. The pathogenesis of hyperuricemic nephropathy involves a variety of factors, including: amino acid metabolism disorder, energy metabolism abnormality, increased nucleotide metabolism, lipid metabolism disorder and bile acid metabolism imbalance, REDOX process disorder, cell cycle and apoptosis imbalance, signal transduction and inflammatory response enhancement, and intestinal flora imbalance.

The association of RBP4 with chronic kidney diseases in southern Chinese population.

Background: Retinol binding protein 4 (RBP4), as a novel adipokine, has been proven to be highly related to insulin resistance, obesity, diabetes, hypertension, hyperuricemia and other metabolic diseases, which are all risk factors for chronic kidney disease (CKD). However, there is a lack of sufficient studies to explore the relationship between RBP4 and CKD, and no reports have described the predictive value of RBP4 for CKD. This study was designed to clarify the relationship between RBP4 and CKD and its potential predictive value.

Renal function and risk of gestational diabetes mellitus: the potential mediating role of carnitine metabolites.

Context: Renal function may play a crucial role in the development of gestational diabetes mellitus (GDM). However, prospective studies on this topic are scarce and the mechanisms remain unclear.

Objective: To assess the associations of early-pregnancy renal function with GDM and the mediating role of carnitine metabolites.

Uric acid in diabetic microvascular complications: Mechanisms and therapy.

Uric acid (UA) is mainly synthesized in the liver, intestine, and vascular endothelium and excreted by the kidney (70 %) and intestine (30 %). Hyperuricemia (HUA) occurs when UA production exceeds excretion. Many studies have found that elevated UA is associated with diabetic microvascular complications (DMC), including diabetic retinopathy (DR), diabetic nephropathy (DN), and diabetic peripheral neuropathy (DPN).

Association between mitophagy and inflammasome in uric acid nephropathy.

Objective: This study was recruited to investigate the role of mitophagy in activating NLRP3 inflammasome in the kidney of uric acid (UA) nephropathy (UAN) rats.

Methods: This study developed a uric acid nephropathy (UAN) rat model divided into five groups: Negative control (NC), UAN model (M), UAN + autophagy inhibitor (3-MA), UAN + lysosome inhibitor (CQ), and ROS scavenger (N-acetylcysteine, N). H&E staining assessed renal structure, ROS levels were measured with 2, 7dichlorofluorescin diacetate, and ELISA measured serum markers (, , cystatin , , , ).

The time-averaged serum uric acid can better predict the prognosis of IgA nephropathy.

Background And Aim: To understand the clinical and pathological characteristics of patients with IgA nephropathy (IgAN) complicated by hyperuricemia, and to analyze the time-averaged SUA (TA-SUA) on the prognosis of IgAN.

Methods And Results: A retrospective analysis of 718 IgAN patients with diagnosis confirmed by renal biopsy and follow-up of more than 1 year was performed. At least two serum uric acid (SUA) levels were measured at intervals of 0.

Focal segmental glomerulosclerosis and neurogenic bladder in a Chinese patient with a novel pathogenic variation in TRIM8 gene: A case report.

To report a novel variation in the TRIM8 gene in a Chinese patient who developed focal segmental glomerulosclerosis (FSGS) and neurogenic bladder. Retrospective analysis of the clinical manifestations, laboratory results, renal biopsy results, and genetic data of the patient with FSGS complicated with neurogenic bladder. The patient was a 6-year and 8-month-old Chinese Zang ethnic boy with low-set ears, widely-spaced eyes (inner canthal distance exceeds the 95th percentile of normal inner canthal distance), a small jaw, and a short neck.

[ (Blume) Miq] maintains uric acid homeostasis via regulating gut microbiota and restrains renal inflammation in hyperuricemic nephropathy.

Introduction: The kidney damage caused by the deposition of uric acid in the kidneys is of urgent need for new treatment drugs due to its complex pathogenesis. (Blume) Miq. Also known as , which has a significant therapeutic effect on hyperuricemia nephropathy (HN), however, the specific mechanism of its action is still unknown.

Anti-hyperuricemic effects of the seeds of Hovenia acerba in hyperuricemia mice.

Ethnopharmacological Relevance: The seeds of Hovenia acerba water extract (HAW) are used as an edible traditional Chinese medicine to treat diseases related to hyperuricemia (HUA).

Aim Of The Study: To evaluate HAW for its anti-HUA effect and to figure out their underlying mechanisms.

Materials And Methods: The anti-HUA effects were evaluated on a mouse model by testing HAW's effects on the levels of serum uric acid (SUA), the biochemical indicators of liver and kidney function, and the histology of liver and kidney.

Associations of serum uric acid-to-high density lipoprotein cholesterol ratio with age-related diseases and mortality among older population in the United States.

Background: Older adults experience numerous physiological and socioeconomic changes that increase the risk of chronic diseases. The uric acid to high-density lipoprotein cholesterol ratio (UHR) has emerged as a potential biomarker for assessing various health conditions. This study aimed to investigate the relationship between UHR and the prevalence of age-related diseases and mortality in a nationally representative sample of older adults in the United States.

Prognostic importance of baseline and changes in serum uric acid for macro/microvascular and mortality outcomes in individuals with type 2 diabetes: The Rio de Janeiro type 2 diabetes cohort.

Aims: To investigate the associations between baseline/changes in serum uric acid (sUA) and the risks for cardiovascular/microvascular outcomes and mortality in a type 2 diabetes cohort.

Methods: Baseline sUA was measured in 685 individuals, and 463 had a second sUA measurement during follow-up; sUA was analyzed as a continuous variable and categorized into sex-specific tertile subgroups and low/high levels (>4.5 mg/dl women; >5.

Preclinical gout is common in the patient with stage 3-5 chronic kidney disease. Relevance of musculoskeletal ultrasound.

Background: One in 10 patients with hyperuricemia may develop gout over time, with urate deposition sometimes asymptomatic. Recent reviews and guidelines support ultrasound (US) to assess asymptomatic hyperuricemic (AH) patients to detect gout lesions, showing double contour (DC) and tophus the highest specificities and positive predictive values. Hyperuricemia and gout are common in chronic kidney disease (CKD), especially with glomerular filtration rate (GFR) <60, and both are associated with worse prognosis, although treatment of AH in CKD is not yet recommended in all guidelines.
