Even though it’s a common disorder of women in their reproductive age , It can occur across all ages and genders. Kidney is involved in almost 38 % of the patients with SLE. 40 to 60 % of patients have overt findings at the time of diagnosis . Patients with SLE can have antiphospholipid antibodies (.
