P.248 Relevance of neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and monocyte/lymphocyte ratio in mood disorders: a literature review

Listeria monocytogenes is a small Gram positive, intracellular bacillus known to cause a foodborne disease in immunocompromised patients and other high-risk groups. The infection that usually is asymptomatic or resembles a mild influenza like disease, in some risk groups can cause meningitis and brain abscesses. In pregnant women, L. monocytogenes may lead to abortion or delivery of an acutely ill infant. We describe a case of L. monocytogenes meningitis occurred in a young puerpera without immunological disorders or other risk factors. We think that because the puerperium is accompanied by the same physiological changes in immune response that features pregnancy, a higher infectious risk should be considered during this period of woman’s life. Therefore, an empiric antimicrobial therapy also for listeriosis should be promptly started in meningitis that arises in post-partum period so to achieve the best outcome of the infection.
