Antibiotic therapy for infectious hemodialysed patients in Bamako: Pharmacokinetic analyses and first improvement suggestions.

Infection which occurs in renal kidney failure patient have to be therapeutically managed immediately and the treatment must be aggressive to be quickly efficient. In Bamako (Mali). Posology adaptation cause a problem in nephrology, especially for the most common used antibiotics to care these infections. Drug dosage is not routinely performed in Bamako. The main objective of this work is to compare anthropometric, clinical and pharmacokinetic profiles and the clinical future between infected hemodialysis patients following an antibiotic therapy in Bamako and Lyon (hospital used as a reference). To reach these objectives, a preliminary punctual study of clinical pharmacokinetic of vancomycin were set up at Bamako, following the personalization therapeutics model from Lyon. Bamako patients' samples were imported to France and dosage analysis were performed at Lyon. BestDose software was used to view and compare complete pharmacokinetic profile. It includes for the first time, in routine, the 50 ml/mn of the renal function during dialyses for 58 patients: 31 for Bamako and 21 for Lyon. The residual concentration at the beginning of the dialysis session was compared. In Bamako, patients are younger, the renal failure is more severe and arteriovenous fistula are never set up, treatments are limited in dose and in duration; the residual concentration before the dialyses are too low; as a consequence, infections are rarely quickly reduced and more especially the death linked to these infections are more important (9 in Bamako versus 1 in Lyon). Urgent corrective measures have to be proposed: propose a conciliation between therapeutic requirements formulated within Lyon protocols and the financial ability of the patient, to promote arteriovenous fistula creation as soon as possible, and develop first dose strategy (unfortunately there is often only one dose): a more aggressive dose estimated from simulation profile performed in this study.
