Summary
Severe post-infectious glomerulonephritis can lead to acute renal failure. This condition is characterized by crescentic and necrotizing glomerulonephritis with C3 deposition, often requiring hemodialysis.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Post-infectious glomerulonephritis (PIGN) is an immune-mediated renal disease.
- It typically follows infections, particularly streptococcal, and can present with acute renal failure.
Observation:
- Two cases of severe PIGN are presented, both with acute renal failure and characteristic pathological findings.
- Case 1 involved a 38-year-old female with lung edema and rapidly progressive renal failure requiring maintenance hemodialysis.
- Case 2 involved a 28-year-old female with pharyngitis and acute renal failure, who improved with hemodialysis but has persistent chronic renal failure.
Findings:
- Renal biopsies in both cases revealed crescentic and necrotizing glomerulonephritis with C3 deposition.
- Immunofluorescence showed granular C3 deposition, with a "starry sky" pattern in one case.
- Electron microscopy identified glomerular subepithelial deposits.
Implications:
- These findings highlight the severe spectrum of PIGN and its potential for poor renal outcomes.
- Aggressive management including hemodialysis and immunosuppression may be necessary.
- Further research into PIGN pathogenesis and treatment is warranted.

Nephrotic 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...
Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
Renal 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...

Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Acute 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,...
Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
