2012, The Egyptian Rheumatologist
Aim of the work: To evaluate the incidence, clinical associations and outcome of APS nephropathy in SLE patients with 2ry APS. Patients and methods: We studied 64 female SLE patients with nephritis; 32 of them had 2ry APS (group 1) and the rest without 2ry APS (group 2). Demographic, clinical and serological data were prospectively evaluated. Systemic lupus erythematosus disease activity index (SLEDAI) and Systemic Lupus International Collaboration Clinics/ACR damage index (SLICC) were assessed. Renal duplex, renal 99m Tc-dimercaptosuccinic) scan (DMSA scan) and renal magnetic resonance angiography (MRA) were all used to detect renal vascular affection. Results: There were statistically significant differences between the two examined groups regarding damage index (p = 0.000), hypertension (p = 0.02), thrombocytopenia (p = 0.000), flLDL (p = 0.008), flC3 (p = 0.01) and TMA (p = 0.04). In group 1: MR angiography detected 7 patients with RAS: 5 patients with renal artery thrombosis that showed a significant association with TMA and proteinuria (p = 0.002, p = 0.004: p < 0.001, p = 0.02, respectively). Patients with RAS had ›DBP, ›s.creatinine and ›TGs (p = 0.004, p = 0.005 and p = 0.0003, respectively). Renal DMSA
