    Insights

    Lactoferrin (LF) levels are significantly elevated in tick-borne encephalitis (TBE) patients, especially in cerebrospinal fluid. Increased LF indicates central nervous system inflammation severity and can monitor treatment effectiveness.

    Area of Science:

    • Neuroscience
    • Immunology
    • Biochemistry

    Background:

    • Tick-borne encephalitis (TBE) is a serious central nervous system (CNS) infection.
    • Assessing CNS inflammation severity and treatment efficacy in TBE requires reliable biomarkers.
    • Lactoferrin (LF) is an iron-binding protein with immunomodulatory functions.

    Purpose of the Study:

    • To investigate lactoferrin (LF) levels in the cerebrospinal fluid (liquor) and blood serum of TBE patients.
    • To evaluate the correlation between LF concentration and TBE severity, including meningeal and focal types.
    • To determine if LF can serve as an objective indicator of CNS inflammation and therapeutic response.

    Main Methods:

    • Immune-enzyme analysis was used to quantify LF concentrations.
    • LF levels were measured in cerebrospinal fluid and serum samples from TBE patients.
    • Control groups included patients with osteochondrosis and healthy donors.

    Main Results:

    • LF concentrations in TBE patients were 1.5-3 times higher than normal in serum.
    • Cerebrospinal fluid LF levels were over 20 times higher at disease onset, decreasing to 6-fold higher after 7 days.
    • A direct correlation was observed between LF levels and the form and severity of TBE.

    Conclusions:

    • Elevated LF levels in cerebrospinal fluid are a significant indicator of CNS inflammation in TBE.
    • LF concentration can serve as an objective marker for assessing TBE severity and activity.
    • LF levels may be a useful criterion for monitoring the effectiveness of TBE therapy.

    Bacterial Phylum Spirochaetes

    Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...

    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.
    Arboviral Encephalitis01:25

    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...

    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...

    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...
