We studied demographic data of all individuals comprising serum creatinine, 24 hours proteinuria, age and gender. Our study showed no difference of serum creatinine and 24 hours proteinuria and lupus nephritis (LN) classes between age below or equal to 40 versus more than 40 years old. In this study also, we found no significant difference of antibody deposited intensity of IgG, C3 and C1q in immunofluorescence study in age below or equal to 40 versus more than 40 years old. Accordingly, no significant difference of LN classes, activity or chronicity percent between ages below or equal to 40 versus more than 40 years old. Moreover, no significant difference of number of sclerotic glomeruli or crescents among patients with ages below or equal to 40 versus more than 40 years old were detected.
