Staphylococcus epidermidis Bacteremia in an Older Patient With Guillain-Barré Syndrome With Fever of Unknown Origin: A Case Report.

Guillain-Barré syndrome (GBS) is an immune-mediated disorder that affects the peripheral nerves, often leading to weakness, numbness, and paralysis. Although GBS does not induce immunosuppression, severe cases can render patients vulnerable to infection due to various complications. We present the case of a 70-year-old woman who developed GBS following a Mycoplasma infection. The patient's prolonged GBS symptoms led to an immunocompromised state, resulting in sepsis due to bacteremia caused by methicillin-resistant Staphylococcus epidermidis. Respiratory muscle paralysis necessitated intubation and mechanical ventilation, predisposing the patient to aspiration pneumonia. Prolonged hospitalization increases the risk of infection, as exemplified by catheter-related bloodstream infections and respiratory bacterial colonization. Although GBS does not inherently suppress immunity, its complications, such as musculoskeletal and respiratory failure, can mimic immunodeficiency, necessitating comprehensive management. A system-based approach should address neurological deficits and potential complications, emphasizing collaboration among medical specialties. This case highlights the importance of recognizing GBS-related challenges and adopting a holistic strategy for effective patient care.
