Chronic Inflammation in Chronic Kidney Disease

Area of Science:

• Nephrology
• Immunology
• Public Health

Background:

• Chronic kidney disease (CKD) affects 10-12% of the global population, posing a significant public health challenge.
• Persistent, low-grade chronic inflammation (CI) is a key factor in the poor prognosis of CKD, particularly in advanced stages.
• CI exacerbates complications such as anemia and atherosclerosis in CKD patients.

Purpose of the Study:

• To review and highlight the complex mechanisms driving the development of chronic inflammation in CKD.
• To provide a comprehensive overview of factors contributing to CI in the context of kidney disease.

Main Methods:

• Literature review focusing on the pathophysiology of chronic inflammation in CKD.
• Analysis of factors including glomerular filtration rate decline, retained substances, inflammatory cytokines, oxidative stress, and gut microbiota alterations.

Main Results:

• Reduced glomerular filtration rate impairs the clearance of inflammatory substances and cytokines.
• Oxidative stress, gut dysbiosis, and alterations in gut microbiota composition are significant contributors to CI in CKD.
• These factors collectively promote a pro-inflammatory state, worsening the CKD progression and its complications.

Conclusions:

• The development of CI in CKD is multifactorial, involving impaired waste clearance and systemic inflammatory responses.
• Targeting these mechanisms, including oxidative stress and gut health, may offer therapeutic strategies to mitigate CI in CKD.
• Further research into the interplay of these factors is essential for improving CKD patient outcomes.
