Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study follows 209 children and adults hospitalized with tick-borne encephalitis (TBE) in the Czech Republic for one year after discharge. Researchers track symptoms like fatigue, headaches, memory problems, and weakness to see how long they last and who needs extra support. The goal is to better understand recovery and help guide vaccination and public health decisions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could improve follow-up care for TBE patients and support vaccination policies to prevent long-term health problems.
What could go wrong
This is an observational study, not a treatment trial, so it won't test any new therapy. Results may not apply outside the Czech Republic.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Hospitalized children and adults with confirmed tick-borne encephalitis (TBE) treated at four infectious disease centers in the Czech Republic. All participants had clinical symptoms of central nervous system involvement, cerebrospinal fluid pleocytosis, and laboratory confirmation of TBEV infection. Patients were enrolled during their acute hospitalization and followed prospectively for up to 12 months as part of a standardized clinical and functional outcome assessment program.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Hospitalization due to suspected central nervous system (CNS) infection. * Laboratory-confirmed TBE, defined as: the presence of CNS symptoms and cerebrospinal fluid pleocytosis (\>5 × 10⁶/L) and TBEV IgM and IgG seropositivity in serum, or detection of TBEV IgM in CSF in previously vaccinated individuals. * All age groups (children and adults). * Ability to participate in scheduled follow-up (in person or via telephone). * Informed consent provided by the patient or legal guardian (for minors). Exclusion Criteria: * Alternative diagnosis explaining the CNS symptoms * Missing essential clinical or laboratory data required to confirm TBE or assess outcomes. * Refusal or inability to provide informed consent. * Inability to complete follow-up assessments, including situations where reliable contact cannot be maintained. * Coexisting severe neurological disorder unrelated to TBE that prevents meaningful evaluation of sequelae (e.g., advanced neurodegenerative disease, severe preexisting motor disability).
