Summary
A fatal case of encephalitis caused by Acanthamoeba, a rare amoeba, occurred in a woman with systemic lupus erythematosus. Diagnosis involved identifying amoebas in brain tissue and confirming Acanthamoeba DNA.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Systemic lupus erythematosus (SLE) is an autoimmune disease that can increase susceptibility to infections.
- Acanthamoeba is a free-living amoeba found in soil and water, capable of causing severe infections.
Observation:
- A 24-year-old woman from India with a history of SLE presented with encephalitis.
- The patient experienced a fatal outcome due to the severe neurological infection.
Findings:
- Diagnosis was established through immunofluorescence analysis of brain tissue, identifying Acanthamoeba.
- Molecular confirmation was achieved by detecting Acanthamoeba mitochondrial 16S rRNA gene DNA in brain tissue sections.
Implications:
- This case highlights the potential for Acanthamoeba encephalitis in immunocompromised individuals, such as those with SLE.
- Early diagnosis and treatment strategies for Acanthamoeba infections in vulnerable populations require further investigation.
- The findings underscore the importance of considering rare pathogens in the differential diagnosis of encephalitis.

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...
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,...
Arboviral 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...
Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
