Abstract
Iako većinom prolaze asimptomatski, u nekih se bolesnika arbovirusne infekcije očituju teškom kliničkom slikom neuroinvazivne bolesti. Ovo istraživanje uključilo je 492 bolesnika s neuroinvazivnom infekcijom oboljelih tijekom četiri uzastopne sezone prijenosa arbovirusa (2017.-2020. godine). Istražena je učestalost virusa krpeljnog encefalitisa (KMEV), West Nile (WNV), Usutu (USUV), Toscana (TOSV), Tahyna orthobunyavirusa (TAHV) i Bhanja bandavirusa (BHAV) određivanjem virusne RNK/specifičnih protutijela. Arbovirusna etiologija dokazana je u 118 (23,9%) bolesnika. U ukupnom broju bolesnika s dokazanom etiologijom, najučestaliji uzročnik je bio WNV (52,5%), zatim KMEV (38,9%), a sporadično su dokazani USUV (2,6%), TOSV (2,6%), TAHV (1,7%) te BHAV (1,7%). Nadalje, NT protutijela na TAHV i BHAV dokazana su u serumu 10,3% te 20,6% bolesnika s nedokazanom etiologijom. Neuroinvazivne arbovirusne infekcije bile su češće u muškarca u odnosu na žene (62,7% naspram 37,3%). Više od polovice oboljelih (55,9%) bilo je u dobi iznad 60 godina. U kliničkoj slici dominirao je meningitis (57,8%) i meningoencefalitis (34,5%). Uočena je karakteristična sezonska pojavnost arbovirusnih infekcija (travanj-listopad). Dokazani arbovirusi bili su geografski rasprostranjeni u kontinentalnim županijama, osim TOSV-a dokazanog na području priobalja. Filogenetska analiza pokazala je prisutnost europskog podtipa KMEV, WNV linije 2 te USUV europske linije 2. Definiranje prevalencije i molekularno-epidemioloških značajki dokazanih arbovirusa predstavlja izvorni znanstveni doprinos epidemiologiji arbovirusnih infekcija.
Abstract (english)
Although mostly asymptomatic, arboviral infections are presented with a severe clinical presentation of a neuroinvasive illness in some patients. A total of 492 patients with neuroinvasive infections were tested for the presence of arboviruses during four consecutive seasons (2017-2020). The prevalence of tick-borne encephalitis (TBEV), West Nile (WNV), Usutu (USUV), Toscana (TOSV), Tahyna orthobunyavirus (TAHV), and Bhanja bandavirus (BHAV) was analyzed by detection of viral RNA/antibodies. Neuroinvasive arboviral infections were confirmed in 118 (23.9%) patients. WNV and TBEV were the most common arboviruses detected in 52.5% and 38.9% of patients, whereas USUV (2.6%), TOSV (2.6%), TAHV (1.7%) and BHAV (1.7%) were detected sporadically. In addition, TAHV and BHAV NT antibodies were documented in serum samples of 10.3% and 20.6% of patients with unknown etiology. Males were infected more commonly (62.7%) than females (37.3%). Patients in the age group >60 years were most commonly affected (55.9%). The majority of patients presented with meningitis (57.7%) and meningoencephalitis (34.5%). Arboviruses showed seasonal distribution (April-October). Infections were detected in continental counties, whereas TOSV was detected at the Croatian littoral. Sequenced strains showed the circulation of the TBEV European subtype, WNV lineage 2, and USUV Europe 2 lineage. Defining the prevalence and molecular epidemiology represents an original scientific contribution to the epidemiology of arboviral infections.
