Summary
Jequirity bean poisoning, though rare, can cause severe neurological damage. This case highlights acute demyelinating encephalitis as a previously unreported manifestation of Abrus precatorius toxicity.
Area of Science:
- Toxicology
- Neurology
- Immunology
Background:
- Jequirity bean (Abrus precatorius) and castor bean poisoning are uncommon but severe toxic events.
- Toxalbumins (abrin and ricin) in these beans inhibit protein synthesis, leading to toxicity.
- Abrus precatorius poisoning is rare and less understood than castor bean poisoning.
Observation:
- A 30-year-old female presented with bloody diarrhea and coma after ingesting 'ratti' seeds.
- Brain MRI revealed acute demyelinating encephalitis.
- The patient succumbed to progressive central nervous system depression within three days.
Findings:
- This case presents a novel manifestation of jequirity bean poisoning: acute demyelinating encephalitis.
- Abrus precatorius toxicity can lead to severe neurological complications.
- The observed demyelination suggests an immune-mediated process.
Implications:
- Abrus precatorius may trigger immune-mediated neurological damage.
- The immunomodulatory properties of Abrus are implicated in its pathogenic mechanism.
- Further research into the immunological pathways of Abrus toxicity is warranted.

01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:19Encephalitis 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...
01:26Encephalitis 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...
01:26Brain 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,...
01:27Cryptococcal 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,...
01:26Anticholinesterase Agents: Poisoning and Treatment
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is slower than the...
