‘The Year of Living Dangerously’: Successful Rhodococcus Equi Therapy in an Immunosuppressed Patient with Minimal Toxicity by One Year of Continuous Intravenous Vancomycin Therapy Combined with Oral Levofloxacin And Rifampicin
Abstract
Background Rhodococcus equi is a Gram-positive microorganism that causes infections, particularly in immunocompromised patients. Treatment duration can be prolonged. While vancomycin is an effective drug in this scenario, its use may lead to renal damage. Studies have shown that continuous vancomycin infusion appears to be a safe strategy in terms of adverse effects compared to bolus administration. Case description We present the case of a 71-year-old female liver transplant recipient. After being diagnosed with a mediastinal infection caused by Rhodococcus equi with poor response to initial therapy, she required 12 months of continuous intravenous domiciliary infusion of vancomycin combined with oral levofloxacin and rifampicin. There was no drug-related complication throughout the follow-up. Conclusions The use of continuous vancomycin infusion has emerged as a safer, more efficient, and cost-effective alternative to intermittent administration. We want to emphasise the uniqueness of this case, where despite the unprecedented treatment duration, no adverse effects occurred. LEARNING POINTS Vancomycin therapy based on continuous infusion represents a safer and cheaper strategy than classic intermittent administration. The use of continuous infusion facilitates the management of complex infections with outpatient antimicrobial therapy.
