Encephalitis ll: Pathophysiology

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...

Arboviral Encephalitis

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...

Encephalitis l: Introduction

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...

Rocky Mountain Spotted Fever

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.

Bacterial Meningitis II: Pathophysiology

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Rabies

Rabies

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...

Summary

Ciliary neutrophic factor (CNTF) levels in serum and cerebrospinal fluid are elevated in patients with tick-borne encephalitis (TBE) and bacterial meningitis. CNTF concentration in CSF may serve as a marker for central nervous system inflammation.

Background:

Tick-borne encephalitis (TBE) and bacterial meningitis are serious central nervous system infections.
Ciliary neutrophic factor (CNTF) is a cytokine implicated in neuronal survival and inflammation.

Purpose of the Study:

To compare serum and cerebrospinal fluid (CSF) concentrations of CNTF in patients with TBE and bacterial meningitis.
To assess changes in CNTF levels following treatment.

Main Methods:

Serum and CSF samples were collected from 49 patients (23 TBE, 16 bacterial meningitis, 10 controls) twice: before and after 4-week treatment.
CNTF concentrations were measured using [specific assay not mentioned in abstract].

Main Results:

CNTF serum levels were significantly higher in TBE and bacterial meningitis groups compared to controls, both before and after treatment.
Patients with TBE showed higher serum CNTF than those with bacterial meningitis.
CSF CNTF levels were elevated in both patient groups compared to controls, with higher concentrations in the bacterial meningitis group.
Following treatment, CNTF levels decreased significantly in both TBE and bacterial meningitis groups, returning to control levels in the TBE group.

Conclusions:

Elevated CNTF in serum and CSF indicates an inflammatory process in the central nervous system.
CSF CNTF concentration may serve as a potential biomarker for differentiating TBE and bacterial meningitis.
CNTF levels decrease with effective treatment for these infections.
