General management and regimen
Management of patients with suspected tick-borne encephalitis requires mandatory hospitalization in a specialized infectious diseases department. The disease often presents with prominent neurological symptoms (ranging from meningeal signs and intense headache to central paresis and bulbar disorders), so patient care is carried out with the constant dynamic involvement of a neurologist.
One of the most important non-pharmacological conditions for successful treatment is strict bed rest. The patient must maintain it until intoxication syndrome is completely resolved. This is a critically important condition necessary to minimize the risk of severe neurological complications.
Specific (etiotropic) therapy
The primary method of etiotropic treatment is the administration of anti-tick immunoglobulin.
The main rule: if the disease progresses and acute neurological symptoms increase, the drug is prescribed empirically, meaning immediately, without waiting for laboratory confirmation of the diagnosis (PCR or ELISA of CSF and blood serum). Administration is performed immediately after collecting biological material for immunological testing.
If laboratory tests confirm the presence of tick-borne encephalitis virus antigens, immunoglobulin administration is continued. Therapy is not stopped until intoxication manifestations completely disappear and stable positive dynamics in the patient's neurological status are observed.
Antibacterial and pathogenetic therapy
Since tick-borne encephalitis is transmitted by ixodid tick bites, there is always a high risk of mixed infection (primarily concurrent infection with Lyme disease). Therefore, the treatment regimen empirically includes antibacterial therapy (e.g., ceftriaxone). If etiotropic therapy for Lyme disease is not started immediately, it may be postponed until positive serological results are obtained.
The pathogenetic therapy complex is prescribed from the first day of hospitalization and includes the following areas:
- Detoxification — relief of general body intoxication.
- Dehydration — to reduce intracranial pressure (especially important in serous meningitis with high CSF pressure and pleocytosis).
- Desensitization — reducing the reactivity of the immune system.
- Oxygen therapy — supplying tissues with oxygen against the background of fever and respiratory disorders.
Diagnostic criteria for starting therapy
The decision on emergency therapy is made based on clinical and epidemiological data. Key factors include staying in an endemic region, tick bites, consumption of unboiled raw milk, as well as an acute onset of the disease with fever up to 39–40°C, nuchal rigidity, and Kernig's and Brudzinski's signs. Cerebrospinal fluid analysis (lumbar puncture) demonstrates lymphocytic pleocytosis, high pressure, and a positive Pandy test, which helps distinguish the disease from purulent (e.g., meningococcal) meningitis and immediately adjust treatment.
Briefly: answers to topical questions
What is the dosage and regimen of anti-tick immunoglobulin for treatment?
Anti-tick immunoglobulin for treatment is administered intramuscularly at a baseline single dose of 0.1 mL/kg of body weight, which can be increased to 0.15 mL/kg in extremely severe cases. The administration regimen depends on the clinical form:
- Febrile form — the drug is administered once daily for a course of 3–5 days until improvement.
- Meningeal form — injections are given every 10–12 hours, with a course duration of at least 5 days.
- Focal forms — the drug is used every 8–10 hours for at least 6 days (until temperature drops and neurological symptoms regress).
What specific drugs are used for dehydration therapy in tick-borne encephalitis?
Osmotic and loop diuretics are prescribed for dehydration therapy in patients with tick-borne encephalitis. Among specific drugs, the educational materials explicitly mention the osmotic diuretic mannitol. This therapy is indicated in the presence of clinical signs of intracranial hypertension and is used to prevent and/or treat cerebral edema.
What are the maximum timeframes after a tick bite for immunoglobulin administration to be effective?
Sources indicate two time limits for emergency immunoglobulin administration after a tick bite: strictly within the first 72 hours; in other materials — within the first 96 hours (4 days, up to and including day 4). After the 4th day, immunoglobulin administration is prohibited or no longer indicated, as during the incubation period it can worsen the course of the disease due to the phenomenon of antibody-dependent enhancement of infection.
Class and exam questions
Can immunoglobulin administration be delayed until PCR results are available?
No. In the presence of pronounced neurological symptoms and severe disease progression, immunoglobulin is administered immediately, right after blood and CSF collection.
Why is ceftriaxone prescribed for viral encephalitis?
Antibiotics are prescribed empirically due to the high probability of mixed infection, primarily for the prevention and treatment of concomitant Lyme disease.
When is a patient allowed to stop strict bed rest?
Bed rest is discontinued only after complete relief of the intoxication syndrome. Early mobilization increases the risk of complications.
