After treatment with steroids and other therapies, active lupus erythematosus usually improves and enters a stable phase. However, factors such as infection, pregnancy, surgery, fatigue, and discontinuation of medication can trigger the transition from a stable phase back to an active phase of lupus erythematosus. The following symptoms should be considered for a possible recurrence of the disease: First, onset of fever without reasons related to colds or infections. Second, appearance of new rashes or vascular-like rashes on fingertips and other areas. Third, recurrence of joint swelling and pain. Fourth, significant hair loss. Fifth, development of fresh ulcers in the mouth or nose. Sixth, development of fluid accumulation in the chest cavity or pericardium. Seventh, increased protein in urine, decrease in white blood cells or platelets, or significant anemia.
