Background: Neurobrucellosis presents diverse clinical challenges and risks of long-term complications.We aimed to assess the relationship between the duration of antibiotic therapy, clinical factors, and the outcome of neurobrucellosis with a case report combined with a systematic review of the literature.We present a case of a 31 years-old man successfully treated at our Institution. We then searched Ovid MEDLINE, Embase and Scopus for articles that encompassed neurobrucellosis cases, duration of treatment, and outcome. The primary outcome was to assess an association between the duration of treatment and the risk of sequelae or relapses. Univariate, multivariate and sensitivity analysis were carried out to define which variables affect​ed​ the clinical outcome. Quality assessment was performed using a dedicated tool.A total of 123 studies were included, totaling 221 patients. Median duration of treatment was 4 months (IQR 3 – 6), 69% patients recovered without sequelae, 27% had sequelae. Additionally, five patients had a relapse, and 4 patients died. Multivariate analysis found that the duration of treatment, age, and the use of ceftriaxone were not associated with a higher risk of sequelae or relapses. A significant association was found for corticosteroids use (OR 0.39, 95% IC 0.16 – 0.96, p = 0.038), motor impairment (OR 0.29, 95% IC 0.14 – 0.62, p = 0.002), and hearing loss (OR 0.037, 95% IC 0.01 – 0.11, p < 0.001).This study highlights the variability in clinical presentations and treatment approaches for neurobrucellosis. Patients with factors indicating higher sequelae risk require meticulous follow-up.Objective: Neurobrucellosis presents diverse clinical challenges and risks of long-term complications.We aimed to assess the relationship between the duration of antibiotic therapy, clinical factors, and the outcome of neurobrucellosis with a case report combined with a systematic review of the literature.We present a case of a 31 years-old man successfully treated at our Institution.
