A case report of diabetic ketoacidosis due to endocarditis of the mitral valve.

In the context of diabetic ketoacidosis, clinicians should consider uncommon origins of infection, notably infective endocarditis. This is especially crucial when confronted with cases that recur persistently or exhibit resistance to treatment. This is a case of a diabetic patient with diabetic ketoacidosis admitted to our facility. A 35-year-old diabetic patient presented with DKA precipitated by mitral valve endocarditis. To our knowledge and according to the literature review, only one case of DKA precipitated by endocarditis has been reported in the past. This report highlights the importance of considering endocarditis as a possible etiology in patients presenting.
