When comparing SLE with psoriasis, SLE is of course more serious. Because SLE is an autoimmune disease that may involve the whole body, some patients may have serious internal organ involvement, such as lupus nephritis, some patients may have gastrointestinal tract involvement, serious lupus myocarditis, or even lupus encephalopathy, and for these patients with internal organ involvement, it can be fatal in severe cases. However, psoriasis is only a skin lesion, the patient’s symptoms are relatively mild, and generally there is no involvement of internal organs, and the treatment is not as complicated as that of SLE, so lupus is more serious.
