2. Antiviral Therapy

• CMV Prophylaxis: For patients at high risk of CMV infection, antiviral prophylaxis with ganciclovir or valganciclovir is often initiated. This is particularly important in the first few months post-transplant.
• Treatment of Established Infections: If a patient develops a confirmed CMV infection, treatment may involve higher doses of ganciclovir or foscarnet, depending on the severity and resistance patterns.

3. Antifungal Therapy

• Prophylaxis: In high-risk patients, antifungal prophylaxis with agents like fluconazole may be initiated to prevent fungal infections.
• Treatment of Invasive Fungal Infections: If a fungal infection is suspected or confirmed, treatment may involve echinocandins (e.g., caspofungin) or azoles (e.g., voriconazole), depending on the specific fungus involved.

4. Supportive Care

• Fluid Management: Maintaining proper hydration and electrolyte balance is crucial, especially in cases of septic shock.
• Nutritional Support: Ensuring adequate nutrition is vital for recovery and immune function, often requiring enteral or parenteral nutrition support.

5. Monitoring and Follow-Up

• Regular Surveillance: Close monitoring for signs of infection, including laboratory tests (e.g., complete blood count, liver function tests) and imaging studies, is essential for early detection and management of infections.
• Adjustment of Immunosuppressive Therapy: In some cases, it may be necessary to adjust the levels of immunosuppressive medications to balance the risk of infection with the need to prevent organ rejection.

Conclusion

Infections following liver transplantation, as indicated by ICD-10 code T86.43, require a multifaceted treatment approach that includes antibiotic, antiviral, and antifungal therapies, along with supportive care and vigilant monitoring. The specific treatment regimen will depend on the type of infection, the patient's overall health, and the results of microbiological testing. Early recognition and prompt management of infections are critical to improving outcomes in liver transplant recipients. Regular follow-up and adjustments to immunosuppressive therapy are also essential to mitigate the risk of infections while ensuring the transplanted liver remains protected from rejection.
