Firstly, systemic lupus erythematosus is an autoimmune disease of unknown etiology, and it can affect multiple organs including the heart, lungs, kidneys, and gastrointestinal tract. Once diagnosed with systemic lupus erythematosus, it is essential to complete routine urine tests, 24-hour urine protein quantification, chest CT, and other related examinations to fully assess the condition and distinguish between mild, moderate, and severe cases. Treatment plans should be formulated based on the assessment of the condition. If it is purely systemic lupus erythematosus without damage to other organs and the condition is stable with reduced maintenance doses of steroids, then pregnancy can be considered. However, during pregnancy, it is crucial to regularly monitor pulmonary arterial hypertension, pulmonary artery pressure, 24-hour urine protein quantification, and kidney function. If complications such as lupus nephritis occur, treatment decisions should be based on the condition. For instance, if there is an increase in creatinine and significant proteinuria, pregnancy is not recommended as it can exacerbate the burden on the kidneys and lead to further deterioration of kidney function.
