Extended drug-resistant Salmonella typhi osteomyelitis: a case report and literature review

Abstract

Abstract Background Salmonella typhi infection commonly results in gastroenteritis, bacteremia with or without secondary seeding, or asymptomatic carrier stage. Few cases of Salmonella typhi bacteremia later result in seeding and ultimately lead to further complications including osteomyelitis and rarely vertebral osteomyelitis. Case presentation We are discussing a case of a 38-year-old Asian male patient, with no known comorbids. He presented with fever and backache for 4 weeks. Based on the magnetic resonance imaging (MRI) findings of the spine and positive blood cultures, a diagnosis of XDR Salmonella typhi (S. typhi) osteomyelitis (OM) was made. Patient was started on intravenous therapy as per culture report which was later modified according to treatment response. Conclusion S. typhi has a broad spectrum of clinical manifestations including osteomyelitis however to the best of our knowledge this is the first reported case of XDR S. typhi vertebral osteomyelitis. We describe the clinical course of the patient and review the literature regarding the treatment of S.typhi vertebral osteomyelitis with a special focus on XDR S. typhi. Treatment course and complications in view of this new resistant strain have to be reported in order to devise general guidelines for the management in such particular cases.
