Abstract
BACKGROUND: Granulomatous mastitis (GM) is a rare inflammatory breast disease primarily affecting reproductive-aged women with a history of breastfeeding. Within GM lesions, Corynebacterium kroppenstedtii has frequently been isolated, suggesting it may play a significant role in the development of GM. It is important to develop the novel therapeutic regimen to fight against the Corynebacterium kroppenstedtii infection. RESULTS: In our study, the combination of vancomycin and the lipid-lowering drug Tetrahydrolipstatin (THL) exhibited a synergistic effect against bacteria. Proteomic analysis revealed that potential targets of THL are involved in intermediary metabolism, cellular respiration, lipid metabolism, signaling pathways, virulence, and detoxification and adaptation processes. CONCLUSIONS: The combination of THL and vancomycin could be a novel therapeutic regimen to enhance clinical outcomes and reduce the recurrence of GM.
