Insights

Posterior reversible encephalopathy syndrome (PRES) in children can be linked to kidney disease. Prompt treatment of blood pressure and seizures is crucial for recovery and preventing severe complications.

Area of Science:

  • Pediatric Nephrology
  • Neurology
  • Critical Care Medicine

Background:

  • Posterior reversible encephalopathy syndrome (PRES) is a neurological condition often seen in cancer patients and linked to kidney disease.
  • Post-streptococcal glomerulonephritis is a common cause of hypertension in children and can precipitate PRES.
  • Early recognition and management of PRES are vital to avert severe, irreversible complications.

Observation:

  • Two pediatric cases of PRES associated with acute post-streptococcal glomerulonephritis are presented.
  • Patients, aged 10 and 15, exhibited symptoms including headaches, visual disturbances, hypertension, and seizures.
  • Cerebral MRI confirmed PRES lesions in both patients.

Findings:

  • Both patients were diagnosed with PRES secondary to acute post-streptococcal glomerulonephritis.
  • Treatment involved antihypertensive and anticonvulsant medications.
  • Patients demonstrated clinical improvement following targeted treatment.

Implications:

  • This case series highlights the importance of considering PRES in pediatric patients with hypertension and neurological symptoms, especially when renal disease is present.
  • Early diagnosis and management of the underlying glomerulonephritis and PRES symptoms can lead to favorable outcomes.
  • Further research into the specific mechanisms linking post-streptococcal glomerulonephritis and PRES in children may improve preventative strategies.

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...

Acute 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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...
