Summary
Necrotizing meningoencephalitis (NME) in a dog was linked to anti-glomerular basement membrane glomerulonephritis, suggesting an immune-mediated cause for the neurological condition.
Area of Science:
- Veterinary Neurology
- Immunopathology
- Canine Pathology
Background:
- Necrotizing meningoencephalitis (NME) is a severe inflammatory brain disease in dogs.
- Immune-mediated conditions can affect multiple organ systems.
- Canine glomerulonephritis presents a diagnostic challenge.
Observation:
- A 2-year-old West Highland white terrier presented with neurological deficits including seizures and altered mentation.
- Post-mortem examination revealed multifocal necrotizing lesions in the diencephalon and mesencephalon.
- Kidney biopsy showed anti-glomerular basement membrane glomerulonephritis.
Findings:
- Histopathology confirmed necrotizing meningoencephalitis.
- Immunofluorescence demonstrated linear IgG and IgM deposition in glomerular basement membranes.
- The concurrent findings suggest a potential link between the encephalitis and glomerulonephritis.
Implications:
- This case supports the hypothesis of an immune-mediated etiology for canine necrotizing meningoencephalitis.
- Understanding the underlying mechanisms of NME may lead to improved diagnostic and therapeutic strategies.
- The association highlights the importance of considering systemic immune-mediated diseases in neurological cases.

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...
01:19Encephalitis 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...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
01:24Nephrotic 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...
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...

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
