| Popis | Tick-borne encephalitis (TBE) virus (TBEV) is transmitted to humans via tick bites. Infection is benign in >90% of the cases but can cause mild (<5%), moderate (<4%), or severe (<1%) encephalitis. We show here that ~10% of patients hospitalized for severe TBE in cohorts from Austria, Czech Republic, and France carry auto-Abs neutralizing IFN-?2, -ß, and/or -? at the onset of disease, contrasting with only ~1% of patients with moderate and mild TBE. These auto-Abs were found in two of eight patients who died and none of 13 with silent infection. The odds ratios (OR) for severe TBE in individuals with these auto-Abs relative to those without them in the general population were 4.9 (95% CI: 1.5–15.9, P < 0.0001) for the neutralization of only 100 pg/ml IFN-?2 and/or -?, and 20.8 (95% CI: 4.5–97.4, P < 0.0001) for the neutralization of 10 ng/ml IFN-?2 and -?. Auto-Abs neutralizing type I IFNs accounted for ~10% of severe TBE cases in these three European cohorts. |
