Community-acquired meningitis and spondylodiscitis in an adult patient with discoid lupus erythematosus.

Acute bacterial meningitis has a high impact on adult mortality worldwide. Community-acquired meningitis (CA-ECM) is a rare and poorly described condition and the available knowledge is based on low evidence research, mainly from case reports. We describe a case of CA-ECM in Portugal in an adult patient with discoid lupus erythematosus under immunomodulatory therapy. A 73-year-old woman was admitted to the emergency department with fever and altered mental status over 48 h. Cerebrospinal fluid analysis showed 185 leukocytes/μL, including 85% neutrophils, hypoglycorrhachia (less than 5 mg/dL) and elevated protein of 423 mg/dL with positive culture for . She was treated with ceftriaxone. Imaging studies also demonstrated spondylodiscitis and arthritis. She responded well to antimicrobial therapy and completed the treatment as an outpatient.
