Glomerulonephritis associated with antibody to glomerular basement membrane
British Medical Journal
|October 5, 1974
Summary
Antibody to glomerular basement membrane disease, identified by immunofluorescence in 2.5% of renal biopsies, often presents as rapidly progressive glomerulonephritis. This autoimmune condition can lead to severe kidney and lung damage.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Antibody to glomerular basement membrane disease is a rare autoimmune condition.
- It is characterized by autoantibodies targeting the glomerular basement membrane.
- This can lead to severe kidney disease and pulmonary hemorrhage.
Purpose of the Study:
- To determine the prevalence of antibody to glomerular basement membrane disease in renal biopsies.
- To characterize the clinical presentation and serological findings in affected patients.
Main Methods:
- Immunofluorescence microscopy on 400 renal biopsy specimens.
- Detection of circulating anti-GBM antibody using passive hemagglutination and indirect immunofluorescence.
- Clinical correlation with patient outcomes.
Main Results:
- Antibody to glomerular basement membrane disease was found in 2.5% (10/400) of biopsies.
- Seven cases presented as rapidly progressive glomerulonephritis (RPGN), five with lung hemorrhage (Goodpasture's syndrome).
- Circulating antibodies were detected in all RPGN patients, and in two of three patients with less severe nephritis.
Conclusions:
- Antibody to glomerular basement membrane disease is an uncommon but significant cause of glomerulonephritis.
- Early diagnosis and treatment are crucial due to the potential for severe kidney and lung damage.
- Persistence of circulating antibodies and lung hemorrhage can occur even after nephrectomy.

01:10Nephrons
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 happens...
01:20Renal Corpuscle
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 capillaries...

01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:29Acute Kidney Injury II: Pathophysiology
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...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
