Chronic Kidney Disease I: Introduction

388
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease II: Clinical Manifestations

394
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Acute Kidney Injury I: Introduction

351
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Chronic Kidney Disease III: Interprofessional Care

238
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Mitochondrial Membranes

15.6K
A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Acute Kidney Injury III: Clinical Manifestations

539
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Area of Science:

  • Nephrology
  • Mitochondrial Biology
  • Pathophysiology

Background:

  • Acute kidney injury (AKI) is a known risk factor for chronic kidney disease (CKD).
  • The transition from AKI to CKD involves mechanisms like nephron loss, inflammation, and endothelial injury.
  • Mitochondrial dysfunction plays a critical role in AKI pathogenesis and recovery.

Purpose of the Study:

  • To review the role of mitochondria in the AKI-to-CKD transition.
  • To explore therapeutic strategies targeting mitochondria for AKI recovery and CKD prevention.

Main Methods:

  • Literature review focusing on the pathophysiology of mitochondria in AKI and CKD progression.
  • Analysis of recent research on mitochondrial homeostasis, bioenergetics, and organelle stress in kidney injury.

Main Results:

  • Damage to mitochondrial function in early AKI contributes to tubular injury and persistent renal insufficiency.
  • Mitochondrial homeostasis dysregulation is a key factor in the AKI-to-CKD transition.
  • Targeting mitochondria shows potential for therapeutic intervention.

Conclusions:

  • Mitochondrial health is crucial for renal recovery after AKI.
  • Therapeutic strategies aimed at mitochondria may hinder AKI progression to CKD.
