Summary
Uncontrolled complement activation causes severe kidney disease like atypical hemolytic uremic syndrome (aHUS). Understanding complement biology and diagnostics is crucial for managing these conditions and their treatments.
Area of Science:
- Immunology
- Nephrology
- Pathophysiology
Background:
- The complement cascade is vital for innate immunity but its overactivation causes severe disease.
- Atypical hemolytic uremic syndrome (aHUS) is a prime example of complement-mediated renal disease.
- Complement activation contributes to various renal and non-renal diseases.
Purpose of the Study:
- To review renal diseases caused by complement overactivation.
- To discuss the broader role of complement in renal disease pathophysiology.
- To highlight anti-complement therapy's significance and side effects for physicians.
Main Methods:
- Literature review of complement-mediated renal diseases.
- Analysis of complement's role in renal pathophysiology.
- Discussion of anti-complement therapies and their implications.
Main Results:
- Atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy are key complement-mediated renal diseases.
- Complement overactivation leads to tissue injury in these conditions.
- Eculizumab, a complement inhibitor, treats aHUS but increases infection risk.
Conclusions:
- Understanding complement biology and diagnostics is essential for managing complement-mediated renal diseases.
- Anti-complement therapies offer treatment benefits but require careful consideration of side effects.
- Physicians need awareness of complement's role in renal pathology and treatment implications.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

8.9K
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a...

481
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...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

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...

6.0K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...
