Symptoms of lupus erythematosus in men may include fever, rash, joint swelling and pain, and foamy urine. 1. The incidence rate of SLE in men and women is about 1:9. It is more prevalent in women of childbearing age, and the incidence rate in men is significantly less than that in women. 2. Clinical manifestations of SLE in men include fever, rash, arthritis, myositis, plasma membrane inflammation, proteinuria, etc. All clinical manifestations of SLE can be found in male patients. 3. Previous studies on SLE patients have found that compared with female patients, male patients have a slightly lower incidence of anemia, arthralgias and anti-dsDNA positivity, while liver and kidney function impairment (symptoms such as foamy urine and lower limb edema) is more common. If you are suffering from SLE, it is recommended that you visit a hospital in a timely manner for standardized diagnosis and treatment.
