We aimed to analyse the relationship between specific inflammatory biomarkers’ levels and the temporal pattern of cerebral venous thrombosis (CVT) symptoms. We performed a retrospective study of adult CVT patients admitted between Jan 01 2006 and Dec 31 2019. We excluded patients with infection at admission, autoimmune, inflammatory or haematological disorders. We evaluated serum inflammatory biomarkers at admission: C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), absolute neutrophil count, absolute lymphocyte count, platelet count, monocyte count, neutrophile-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), bilirubin and monocyte-to-HDL ratio (M-HDLR). These were evaluated according to the time from symptom onset (acute, subacute or chronic). We included 78 patients with CVT (mean age 41 ± 13 years). Neutrophil count (p = 0.017), monocyte (p = 0.024), CRP (p = 0.004), NLR (p<0.001) and LMR (p = 0.004) showed significant variation with CVT duration. Acute onset CVT exhibited higher absolute neutrophil count and NLR but lower LMR. The subacute group had higher monocyte values, and the chronic phase patients displayed higher LMR, but lower CRP. ESR, PLR and M-HDLR showed a tendency to decrease in the chronic phase. We did not observe any statistical difference between the duration of symptoms and levels of bilirubin. CVT patients present a differential inflammatory pattern along the time course of the disease: higher NLR and lower LMR in acute phase, and higher LMR and lower CRP level during the chronic phase. These differences may help to ascertain the onset of poorly defined symptoms and provide input regarding anticoagulation management.
