Clinical Trial Summary

To compare effect of intra-nodal injection of gentamicin versus placebo on the outcome at 28 days of suppurated cat scratch disease's (CSD) lymphadenitis treated by oral azithromycin.

Description:

Double blind controlled study versus placebo. Patients with suppurated CSD's lymphadenitis will receive immediately after the pus aspiration (performed for a diagnostic purpose) an intra-nodal injection of gentamicin or of placebo (NaCl 0,9%) and be treated with oral azithromycin for 5 days.

Intervention

Drug:
• gentamicin
After inclusion in the study, patient will be randomized. According to randomization, patient will receive an intra-nodal injection of gentamicin . As well, azithromycin will be prescribed for all patients for 5 days. Patients will be followed-up each week until week 4 (Day 28).
• placebo
After inclusion in the study, patient will be randomized. According to randomization, patient will receive an intra-nodal injection of placebo. As well, azithromycin will be prescribed for all patients for 5 days. Patients will be followed-up each week until week 4 (Day 28).
