Clinical Scorecard: Effective Recovery of a PICC Line in a Catheter-Related Bloodstream Infection Due to Multidrug-Resistant Ralstonia mannitolilytica with Topical Minocycline: A Case Study

At a Glance

Key Highlights

• Successful management of CRBSI with topical minocycline despite multidrug resistance.
• PICC catheter retained through salvage therapy in a critically ill patient.
• Standard treatment for CRBSI includes catheter removal and systemic antibiotics.

Guideline-Based Recommendations

Diagnosis

• Blood cultures from both peripheral venous and PICC catheter.
• Gram staining and identification via MALDI-TOF MS.

Management

• Immediate catheter removal and systemic antibiotics are standard; topical minocycline can be considered.

Monitoring & Follow-up

• Regular assessment of catheter site and blood cultures to monitor infection resolution.

Risks

• High mortality rate (up to 10%) in immunocompromised patients infected with Ralstonia mannitolilytica.

Patient & Prescribing Data

Immunocompromised individuals with CRBSI and limited vascular access.

Topical minocycline combined with systemic ceftazidime was effective in controlling infection.

Clinical Best Practices

• Strict aseptic technique during blood culture collection.
• Use of topical antimicrobial therapy in cases where catheter removal is not feasible.
