Viral clade is associated with severity of symptomatic genotype 3 hepatitis E virus infections in Belgium, 2010-2018.

Background & Aims: HEV genotype (gt) 3 infections are prevalent in high-income countries and display a wide spectrum of clinical presentations. Host - but not viral - factors are reported to be associated with worse clinical outcomes.

Methods: Demographic, clinical, and biochemical data laboratory-confirmed HEV infections (by PCR and/or a combination of IgM and IgG serology) at the Belgian National Reference Centre between January 2010 and June 2018 were collected using standardised case report forms.

Vertebral osteomyelitis with spinal epidural abscess in two patients with Bacteroides fragilis bacteraemia.

We report 2 cases of vertebral osteomyelitis and contiguous epidural abscess due to Bacteroides fragilis with no concomitant or past intra-abdominal infection. Decompressive surgery with laminectomy was required for both patients due to the occurrence of neurologic deficits. Clinical recovery was achieved after 8 weeks of antibiotic therapy.
