We propose a guideline about the risk, prevention and treatment of infection in the patient under immunomodulatory or immunosuppressive therapy in the context of autoimmune or autoinflammatory disease. It is divided into three sections: drugs and associated risk of infection; immunizations; risk, prevention, and treatment of specific infections. The treatment of autoimmune diseases involves the use of immunosuppressive or immunomodulatory therapies, with an increasing number of new drugs being used. It is associated with an increased risk of infection, which may be present globally or only for specific agents, varying widely depending on the pharmacological class and even within the same class. The prevention strategy and clinical management need to be individually tailored and there are several key factors: characterization of the disease that prompts the immunosuppression, understanding of the mechanism of action of the immunosuppressive drug, knowledge of previous infections, recognition of risk factors, laboratory test results, vaccine administration, monitoring of clinical signs and symptoms and patient education.

Lyme disease is an endemic zoonosis, the most prevalent tick-transmitted infection in temperate areas of Europe, North America and Asia. It is a multisystemic disease with cutaneous, musculoskeletal, neurologic and cardiac manifestations, according to the stage of the disease. We describe a case of late neuroborreliosis in an Erasmus programme student living in Porto. We discuss the importance of the epidemiological suspicion, the clinical approach, the diagnostic criteria and the most adequate treatment.
