Brief Summary

West Nile virus (WNV) is a mosquito-borne virus which in majority of cases causes only self-limited disease. Despite that, in minority of cases (\~0.5%) it can infect the brain and cause severe and even life-threatening disease (neuroinvasive disease). Recent study has shown that up to 40% of WNV patients who develop neuroinvasive disease, have antibodies against Interferons (anti-Type I interferon autoantibodies), which neutralizes interferons, and could explain the development of severe disease. The investigators therefore assume that early treatment with interferon beta (the type of interferon against which most patients do not have neutralizing antibodies) could prevent the development of severe neuroinvasive WNV disease.

Outcome Measures

Primary Outcomes (2)

  • Rates of death or intubation

    Death or intubation within 4 weeks

    4 weeks

  • Modified Rankin Scale (mRS) score

    Comparison of modified Rankin Scale (mRS) score at 3 and 6 months. The mRS score is a 7 point (0-6) disability scale with higher score suggesting higher level of disability.

    3 and 6 months

Secondary Outcomes (5)

  • ICU admission

    4 weeks

  • Mechanical ventilation

    4 weeks

  • Modified-NIH-stroke-scale (mNIHSS)

    3 months

  • Mini-mental state examination (MMSE)

    3 months

  • All cause mortality

    12 months

PLACEBO COMPARATOR

Patients enrolled to participate in the placebo arm will receive 3 subcutaneous injections of normal saline, given 48h hours apart.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • We aim to focus on three patients' populations:
  • Patients older than 70 years of age, who are at higher risk for the presence of neutralizing anti-Type I IFN auto-antibodies, and therefore at higher risk for developing severe neuroinvasive disease. Only patients who fulfill the diagnostic criteria above will be included.
  • Patients presenting with neuroinvasive WNV disease, including either flaccid paralysis or encephalitis, independent of their age, excluding a presentation consistent with isolated aseptic meningitis (headache, fever, 6th nerve palsy). Only patients who fulfill the diagnostic criteria above will be included.
  • Immunocompromised patients at any age. Immunocompromised patients will be defined as patients with hematologic malignancy (treated or untreated); chemotherapy within previous 4 weeks, stem cell transplant recipient or solid organ transplant recipient; use of any immunosuppressant drug including prednisone greater than or equal to 20 mg/day within the previous 4 weeks; primary / acquired immunodeficiency disorder. Only patients who fulfill the diagnostic criteria above will be included.

You may not qualify if:

  • Patients younger than 18 years old.
  • Pregnant women.
  • Contraindication for the administration of the drug: Hypersensitivity to natural or recombinant interferon beta, and decompensated liver disease.
  • A patient with neuroinvasive disease showing consistent spontaneous improvement over a period of \> 2 days and mRS of below 4.
  • More than 8 days from onset of neurological symptoms in immunocompetent patients and more than 10 days in immunocompromised patients. This time frame will be renewed if a patient with flaccid paralysis develops new onset encephalitis.
  • Patients who are receiving active chemotherapy treatment or suffer concurrent severe viral infection.
