Insights

Thrombotic thrombocytopenic purpura (TTP) is a rare childhood disorder. Plasma exchange therapy effectively treated TTP in two young patients, rapidly resolving their symptoms and encephalopathy.

Area of Science:

  • Pediatric Hematology
  • Neurology
  • Transfusion Medicine

Background:

  • Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening condition characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ damage.
  • Childhood TTP is exceptionally rare, presenting diagnostic and therapeutic challenges in pediatric populations.

Observation:

  • Two pediatric patients under 13 years of age presented with clinical manifestations consistent with TTP.
  • Both patients exhibited neurological symptoms, indicative of TTP-associated encephalopathy.

Findings:

  • Plasma exchange therapy was initiated in both pediatric TTP cases.
  • Rapid and complete resolution of hematological abnormalities and neurological symptoms was observed following plasma exchange.

Implications:

  • This case series highlights plasma exchange as a highly effective treatment modality for TTP in children.
  • Early diagnosis and prompt initiation of plasma exchange can significantly improve outcomes for children with TTP, including those with encephalopathy.
  • Further research into the specific mechanisms and long-term effects of TTP in pediatric patients is warranted.

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

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...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
Hepatic Encephalopathy01:29

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 shunting—including...
