BACKGROUND: Solute and water transport by peritoneal membrane has significant variation between patients; the function changes significantly over time. This affects treatment outcomes requires individual approaches. AIM: To evaluate influence of baseline state, its dynamics during dialysis possibility long-term modification. MATERIALS AND METHODS: The solutes (in equilibrium test, PET) mini-PET) was evaluated in a prospective interventional open-label study with historical control among 96 unselected consecutive patients admitted three centers unified program monitoring protection. RESULTS: Compared to matched standard arm, increase solute slower (by 9.5%) observation group. Ultrafiltration classical PET decreased more slowly 28%). At ultrafiltration satisfactory (the proportion less 400 ml 7.6%); small pores did not decrease (−1.1 ± 5.9 ml/year), total 32.1 8.2 ml/year) due free 29.9 7.6 ml/year). Negative associated glucose load monthly greater than 2.68 kg/month. More one case peritonitis rapid decline transport. comorbidity increased 34 patients, median first/last scores 5 (4–6) 6 (4–7) points; (Wilcoxon Z = −5.423; p 0.001). When analyzed separately category, worsening index observed only for high average transporters (Z −2.754, 0.006 −3.357, 0.001, respectively). CONCLUSIONS: interaction transport, primarily cardiovascular disease is certainly two-way: deterioration balance loss effective leads volume overload progression disease. On other hand, contributes damage. most sensitive interventions effectiveness protection preventing separate measuring through ultrapores, which simultaneously reveals feature progressive fibrosis, potential precursor encapsulating sclerosis.

During long-term peritoneal dialysis, fibrosis (PF) often happens and results in ultrafiltration failure, which directly leads to the termination of dialysis. The accumulation extracellular matrix produced from an increasing number myofibroblasts was a hallmark characteristic PF. To date, glucose degradation products (GDPs, i.e., methylglyoxal (MGO)) that appeared during heating storage dialysate are considered be key components initiating PF, but how GDPs lead activation myofibroblast fibrotic peritoneum has not yet been fully elucidated. In this study, mesothelial cell line (MeT-5A) fibroblast (MRC-5) were used investigate transcriptomic proteomic changes unveil underlying mechanism MGO-induced Our data MGO-stimulated cells showed upregulation genes involved pro-inflammatory, apoptotic, pathways. While no phenotypic noted on fibroblasts after direct MGO, supernatant promoted change into proto-myofibroblasts, activated first stage toward myofibroblasts. conclusion, study fibroblast-to-proto-myofibroblast transition; however, additional involvement other factors or (e.g., macrophages) may needed complete transformation

This study aimed to investigate the potential relationship between baseline glucose lymphocyte ratio (GLR) levels and first episode of peritonitis in patients treated with peritoneal dialysis (PD). A total 314 PD were included divided into three groups based on GLR tertiles: tertile 1 (GLR ≤ 4.23); 2 (4.23 < 5.96), 3 > 5.96). The relationships analyzed using Kaplan–Meier curves multivariable Cox regression models. Competitive risk analysis, subgroup sensitivity analyses performed validate robustness findings. During a median follow-up 27 months, 123 (39.17%) developed peritonitis. incidence increased higher tertiles (tertile 1: 32.08%, 2: 37.50%, 3: 48.08%). revealed significant differences cumulative among (Log-Rank test, P = 0.018). After full adjustment for confounding factors, remained at significantly compared those (HR 2.633, 95% CI 1.223–5.668, 0.013). models analysis further confirmed this association. Our suggests that elevated is associated an PD.

Peritoneal dialysis (PD) is considered a life-saving treatment for end-stage renal disease. However, prolonged PD use can lead to the development of peritoneal fibrosis (PF), diminishing its efficacy. mesothelial cells (PMCs) are key initiators PF when they become damaged. Exposure high glucose‑based fluids (PDFs) contributes by directly affecting highly metabolically active PMCs. Recent research indicates that PMCs undergo metabolic reprogramming exposed high-glucose PDFs, including enhanced glycolysis, impaired oxidative phosphorylation, abnormal lipid metabolism, and mitochondrial dysfunction. Although this transition temporarily compensates cellular damage maintains energy levels, long-term impact on tissue concerning. Multiple studies have identified close association between shift in metabolism PF, may promote progression through various molecular mechanisms. This review explores recent findings regarding role mechanism PMC progression. Moreover, it provides summary potential therapeutic strategies aimed at processes, glucose function. The establishes targeting be novel strategy preventing treating PD-associated fibrosis. Overview associated with implications. Under physiological conditions, primarily produce ATP OXPHOS FAO maintain functions. High-glucose PDFs induce PMCs, characterized increased polyol pathway, PPP, inhibited OXPHOS, FAO, exocytosis deposition, These changes multiple pathways.

Individuals with type 2 diabetes mellitus (T2DM) not only face the risk of difficult wound healing after trauma or surgery but also struggle scar formation healing. However, relationship between T2DM and hypertrophic scars (HS) remains unclear. First, data sets related to HS were downloaded from OpenGWAS database. Second, inverse variance-weighted (IVW) technique was employed assess causal impact on utilizing mendelian randomization (MR). Finally, sensitivity analyses reverse MR performed determine robustness findings examine potential for causation. A positive observed. Three suitable datasets analysis obtained using ids ebi-a-GCST006867, ebi-a-GCST007515, ebi-a-GCST007516 (A total 206,572 cases 753,191 controls included).

ABSTRACT AZ505, a highly selective inhibitor of SMYD2, exhibits an antifibrotic effect in renal fibrosis. Its on peritoneal fibrosis remains unexplored. In this study, we investigated its effects the development induced by chlorhexidine gluconate (CG) murine model. We found that SMYD2 and trimethylated histone substrate H3K36 (H3K36me3) were expressed tissue following CG injection, administration AZ505 remarkably inhibited their expression, along with attenuating CG–induced expression collagen I fibronectin. Moreover, also significantly reduced CD31 (marker angiogenesis) CD68‐positive macrophage infiltration CG‐injured peritoneum. further CG‐induced epithelial‐to‐mesenchymal transition (EMT) mesothelial cells, manifested decreasing α‐smooth muscle antigen (α‐SMA) Vimentin restoring E‐cadherin accompanied suppressing two transcription factors, Snail Twist. Finally, phosphorylation AKT increased phosphatase tensin (PTEN), key phosphatase. These data suggest may protect against inhibiting EMT, inflammation angiogenesis, due to blockade methylation modification catalysed SMYD2.

Peritoneal dialysis adoption and technique survival is affected by limitations related to peritoneal membrane longevity metabolic alterations. Indeed, almost all fluids exploit glucose as an osmotic agent that rapidly diffuses across the membrane, potentially resulting in abnormalities such hyperglycemia, hyperinsulinemia, obesity, hyperlipidemia. Moreover, glucose-degradation products generated during heat sterilization, other than itself, induce significant morphological functional changes peritoneum leading ultrafiltration failure. The partial substitution of with agents characterized a better local systemic biocompatibility has been suggested potential strategy innovate fluids. approach aims minimize glucose-associated toxicity, preserving welfare counteracting common comorbidities.

Dyslipidemia is a common metabolic complication in patients undergoing peritoneal dialysis (PD) and has traditionally been viewed primarily terms of cardiovascular risk. Current guidelines do not recommend initiating lipid-lowering therapy due to insufficient evidence its benefits on mortality. However, the impact dyslipidemia PD may extend beyond concerns, influencing PD-related outcomes such as ultrafiltration rate, residual kidney function, technique survival, overall This review challenges traditional perspective by discussing dyslipidemia’s potential role complications, which account for observed link between increased all-cause mortality patients. It explores pathophysiology PD, molecular mechanisms linking membrane dysfunction, summarizes clinical supporting this hypothesis. In addition, paper examines therapeutic strategies manage improve function patient outcomes. The calls future research investigate contributor dysfunction develop targeted interventions
