This clinical trial focuses on the treatment of a condition known as cat scratch disease, which can cause swollen and painful lymph nodes, a condition referred to as lymphadenitis. The study is investigating the effectiveness of an injection of a medication called gentamicin directly into the lymph nodes. This is being compared to a placebo to see if it helps improve the condition over a period of 28 days. Participants in the study will also be treated with an oral antibiotic called azithromycin, which is commonly used to treat infections.

The purpose of the study is to determine if the injection of gentamicin can lead to a better outcome for patients with suppurative cat scratch disease’s lymphadenitis, which is a form of the disease where the lymph nodes become filled with pus. The study will monitor the reduction in the size of the lymph nodes and the need for additional medical procedures, such as needle aspirations or surgery, over the course of the study.

Participants will be observed for changes in their condition, including the size of the lymph nodes and the level of pain experienced. The study will also assess the safety of the gentamicin injection and monitor for any potential resistance to the antibiotics used. The trial aims to provide valuable information on whether this treatment approach can offer a more effective solution for managing this condition.
