Systemic lupus erythematosus (SLE) is a disease characterized by clinical heterogeneity with unpredictable course. Several disease endotypes have been identified, including SLE with antiphospholipid syndrome (APS). We report a case of a pregnant woman with hypertension and proteinuria, diagnosed with APS, Libman-Sacks endocarditis that led to moderate to severe mitral valve insufficiency, and SLE. We describe the diagnostic steps, evolution, and complications. This case highlights the asynchrony behavior of SLE, emphasizing the importance of a multidisciplinary approach to an early diagnosis.
Keywords: antiphospholipid syndrome; hypertension; libman-sacks endocarditis; pre-eclampsia; proteinuria; systemic lupus erythematosus.
