The diseases seen by the Department of Rheumatology and Immunology include rheumatic fever, rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, psoriatic arthritis, reactive arthritis, dry syndrome, as well as microscopic polyangiitis, polymyositis, systemic sclerosis, osteoarthritis, and gout, all of which fall under the scope of rheumatology and immunology visits. If a patient has unexplained fever, multisystem involvement, joint swelling and pain, as well as clinical symptoms such as dry mouth, dry eyes, hair loss, and facial erythema, it is recommended to come to the rheumatology department as soon as possible to further clarify which specific rheumatic disease the patient belongs to. Patients should be further screened for anti-nuclear antibodies, blood sedimentation, C-reactive protein, anti-ENA spectrum, rheumatoid factor, anti-CCP antibodies and other indicators to clarify the diagnosis as soon as possible.
