People who inject drugs are disproportionately affected by acute/chronic bacterial and viral infections that are a cause of significant morbidity. Clinical presentations to the acute medical take vary from skin and soft tissue infections to complications of bacteraemias, and can be challenging with difficulties in adherence, pain management, early self-discharges and loss to follow-up. This review summarises the most recent UK epidemiology of injecting drug use and infection as well as clinical presentation and management.

Sepsis-associated encephalopathy (SAE) describes acute cognitive dysfunction secondary to systemic or peripheral infection occurring outside of the central nervous system (CNS). Symptoms can range from mild confusion to coma and may precede the clinical signs of sepsis. Recognition that SAE is a potential differential diagnosis in patients presenting with delirium is important, as SAE is a diagnosis of exclusion. ⋯ Although mortality is often secondary to multiorgan failure rather than neurological sequelae, long-term cognitive and psychological morbidities have been reported in sepsis survivors. Early treatment (which can include prompt identification and source control of the infection) and good supportive care might improve cognitive outcomes. Future work should aim to improve understanding of both acute and chronic SAE with a focus on therapeutic interventions and improving patient outcomes.
