Abstract
We present a 65 year old diabetic patient with a complex liver abscess and bacteraemia from Lactobacillus paracasei. The abscess resulted in a prolonged hospital stay due to ongoing sepsis despite ultrasound-guided drainage and broad spectrum antibiotics. Furthermore, the patient developed several secondary complications including a right sided pleural effusion, an inferior vena cava thrombus and septic lung emboli. The abscess was eventually managed successfully with a prolonged course of antibiotics and multiple ultrasound-guided drainage procedures.
To our knowledge, this is the first reported case of probiotic consumption, confirmed by strain identification, as the source of a liver abscess. Probiotic products have been widely used for many years and are advocated to the general public for their health benefits with no warning of side effects. Lactobacilli are one group of bacteria commonly used in these products. Although rare, serious complications have been reported. Susceptible patients, such as those who are immunocompromised, should be advised against excessive consumption.
