Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease characterized by production of a number of antinuclear antibodies. Podocyte injury is an important feature and can be detected by several markers including podocalyxin. We aimed to evaluate the impact of SLE on urinary levels of podocalyxin and to determine its relationship to renal biopsy, proteinuria, and disease activity in lupus nephritis (LN) patients. Sixty individuals were recruited; 30 SLE patients with LN as well as 30 healthy volunteers and they were subjected to full history, clinical examination, kidney function, protein/creatinine ratio, urinary podocalyxin, and kidney biopsy. Patients with LN had higher level of urinary podocalyxin (3.96 ± 2.24) than the other group (0 ± 0), (P <0.001). Class IV LN was the most common class found among LN patients [18 cases (60%)]. There was a statistically significant positive correlation between SLE disease activity index score, protein/creatinine ratio, and urinary podocalyxin (P <0.001, r = 0.98) (P <0.001, r = 0.765). There was a statistically significant negative correlation between serum albumin, serum calcium, and urinary podocalyxin (P = 0.001, r = -0.589) (P = 0.025, r = -0.407). Urinary podocalyxin level significantly predicts the pathological impact of SLE on the kidney and could be used as a noninvasive marker for such effect and its progression.
