Case Report of Salmonella and HHV-6 Meningitis in an Infant

Bacterial meningitis is one of the most serious infections. Salmonella meningitis is associated with a high prevalence of long-term adverse outcomes, often linked to acute complications and a broad range of potential neurological sequelae following the infection. Acute complications such as brain abscesses and chronic complications such as hearing loss and developmental delay. In this report, we present a case of a 2-month-old male patient with seizures, hypoactivity and respiratory symptoms, who was found to have Salmonella bacteremia complicated by Salmonella and Human Herpes Virus-6 (HHV-6) meningitis, as well as rhinovirus bronchiolitis, along with follow-up findings. The patient's data, including demographics, presenting symptoms, physical examination findings, and whole exome sequence results, as well as investigations such as complete blood count (CBC), cerebrospinal fluid (CSF) analysis, liver enzyme levels, and imaging findings, were collected from the electronic medical record system using a case report form. In addition, immunological workups were performed, as serious Salmonella infections were more common in immunocompromised patients. In the literature, there was no clear correlation between Salmonella and HHV-6 meningitis, rhinovirus bronchiolitis, and the complications that developed in this infant. This case report provides valuable insights into the clinical spectrum and long-term outcomes of patients with Salmonella meningitis.
