There is no conclusion as to which is more serious, dermatomyositis or SLE, and it is impossible to compare the severity of the two, as both can be life-threatening, and both can be effectively treated to achieve clinical remission.
Dermatomyositis is a chronic inflammatory disease with characteristic skin rashes and malignant tumors, but it can be relieved with aggressive treatment, but is prone to recurrence.
Systemic lupus erythematosus (SLE) is also incurable. It can be improved through early diagnosis and active and rational treatment. However, without early diagnosis and reasonable treatment, it can be complicated by serious organ damage and endanger life.
Therefore, both diseases should be diagnosed and treated early to avoid life-threatening situations.
It is recommended that patients seek timely medical treatment to avoid delays.
