Summary
Inflammatory biomarkers like CCL2, TNF-α, and IL-17 may predict outcomes in peritoneal dialysis patients. Elevated CCL2 and IL-17, and reduced TNF-α, indicate higher risks of mortality or transfer to hemodialysis.
Area of Science:
- Nephrology
- Immunology
- Biomarker Research
Background:
- Peritoneal dialysis (PD) is a vital renal replacement therapy.
- Identifying predictors of adverse outcomes in PD patients is crucial for improving patient management.
- Inflammatory processes are implicated in the progression of kidney disease and PD complications.
Purpose of the Study:
- To assess specific inflammatory biomarkers in patients undergoing PD.
- To determine the association between these biomarkers and the risk of all-cause mortality.
- To investigate the link between biomarkers and transfer to hemodialysis.
Main Methods:
- Prospective cohort study of 43 PD patients.
- Measurement of plasma cytokine levels via flow cytometry and ELISA.
- Categorization of biomarkers by median values and survival analysis using Kaplan-Meier estimator.
Main Results:
- Higher CCL2 and lower TNF-α plasma levels were associated with increased risk.
- Median dialysate IL-17 levels also correlated with higher risk.
- These associations were observed after adjusting for confounding factors over a 16-month follow-up.
Conclusions:
- Specific inflammatory biomarkers show potential for predicting mortality in PD patients.
- These biomarkers may also predict the need for transfer to hemodialysis.
- Inflammatory markers could serve as valuable prognostic tools in PD management.

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

4.8K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
