Abstract

The incidence of postdural puncture headache (PDPH) in relation to pre-existing chronic headache (CH) was assessed, as was the clinical course of CH, at one, three, and six months after PDPH. The study was conducted as a single center cohort prospective study that included 252 patients (105 men and 147 women), average age of 47.3 ± 15.0 years, on whom lumbar puncture (LP) was performed. PDPH was reported in 133 (52.8%) patients; CH was reported in 82 (32.5%) patients. Patients with CH were more likely to have PDPH (p = 0.003). The individual clinical type of CH did not have an effect on the incidence of PDPH (p = 0.128). Patients with PDPH had a clinical deterioration of CH three and six months after LP (p = 0.047, p = 0.027, respectively) in terms of increased headache days per month and/or incomplete efficacy of performed therapy in relation to baseline values. Six months after LP, the worsening of CH was more common in women with PDPH (OR 5,687 [95% CI: 1526-21,200], p = 0.010) and patients with a longer history of CH (OR 1064 [95% CI: 1007-1124], p = 0.027). Multivariate analysis confirmed the direct association of female sex and duration of CH and its worsening six months after PDPH (OR 4478 [95% CI: 1149-17,452], p = 0.031; OR 1448 [95% CI: 1292-1808], p = 0.022). The presented results could be significant for the prediction/differential diagnosis of PDPH in patients with CH and for the prediction/prevention of CH clinical worsening after PDPH.
