Leukocytosis with lymphocytopenia, mild anaemia, thrombocytopenia, elevated liver and muscle enzymes and hyponatremia are occasionally present in patients with WNND. Cerebrospinal fluid (CSF) findings resemble other viral neuroinfections. The purpose of this study is to present some of the most important laboratory findings of our patients with WNND and to evaluate their correlation with fatal outcome.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold>The study included 161 patients with WNND. Their blood and CSF samples were cytobiochemically analysed and the obtained variables were then tested for predictive significance of the disease outcome, or used for differentiation between two clinical syndromes (encephalitis vs meningitis).<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold>West Nile encephalitis was present in 127 (78.9%) patients and West Nile meningitis was diagnosed in 34 (21.1%) cases. Leukocytosis was found in 45.9% patients. CRP level higher than 100 mg\/L was registered only in those with encephalitis (p=0.020). CSF leukocyte count was 146\u00b1171 per microlitre, with slight lymphocytic predominance (mean 52%). Hypoglycorrhachia was registered in 9.3% of our patients with WNND. Twenty-eight (17.4%) patients died and all of them had encephalitis. Independent predictors of fatal outcome in WNND were serum CRP &gt; 100 mg\/L (p=0.011) and CSF proteins &gt; 1 g\/L (p=0.002).<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold>WNND usually affects older males. Prolonged neutrophilic predominance in CSF can occasionally be present, as well as hypoglycorrhachia. Patients with encephalitis, high serum CRP and high CSF protein level have a higher risk of fatal outcome.<\/jats:p>","DOI":"10.1515\/jomb-2016-0022","type":"journal-article","created":{"date-parts":[[2016,8,3]],"date-time":"2016-08-03T07:51:55Z","timestamp":1470210715000},"page":"451-457","source":"Crossref","is-referenced-by-count":14,"title":["The
