Use of Doxycycline in a Renal Impaired Patient with Enterococcal Sepsis

Abstract

Aim: This report highlights the use of doxycycline therapy other than the more standard regimen that includes an aminoglycoside in the management of enterococcal infection in patients with renal impairment without causing further damages to the kidney due to aminoglycoside therapy. Presentation of Case: A case of enterococcal septicemia in a 29-year-old woman who was admitted on account of acute kidney injury secondary to pregnancy induced hypertension in the setting of pre-eclampsia. She was referred from another centre where she had emergency caesarean section done on account of severe pre-eclampsia at 36 weeks gestational age. Blood culture yielded Enterococcus species. When other antibiotic regimen failed, she was started on doxycycline. Patient had good clinical response and was discharged 7 days after commencement of doxycycline. Discussion: Enterococci have emerged as important agent of human disease largely because of their resistance to antimicrobial agents. They are important nosocomial pathogens capable of causing serious and potentially life-threatening infections, including sepsis. The incidence of enterococcal infections, mainly hospital-acquired, has increased over the past 2 decades and isolates with novel mechanism of resistance to antimicrobial agents are more and more frequent. Furthermore, they have great capacity for transmitting these resistances to other species and even to other genera. Conclusion: Doxycycline is a safe and effective alternative antibiotic for the treatment of enterococcal sepsis in patients with impaired renal status.
