Glucocorticoids Induced End Organs Damage in Patients with Systemic Lupus Erythematosus

Abstract

Background: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that affects multiple organs and requires long term treatment with GCs. GC-related end organ damage in SLE appears in the form of: osteoporosis, Avascular Necrosis (AVN), cataracts, diabetes (DM) and cardiovascular disease. Aim of the work: the present work was to assess the prevalence of the complications in SLE patients who were treated with GCs for long periods and with moderate to severe cumulative steroid doses. Patients and Methods: This study was done on 50 SLE patients who fulfilled the SLICC criteria for diagnosis of SLE. All patients subjected to full history taking, clinical examination, slit-lamp examination to assess cataract, laboratory investigations (ESR, CRP, FBS, 2-H PP, CBC, C3, C4 and anti-dsDNA), DEXA scan, MRI scan (when needed), SLEDAI score and SLICC score assessments. All data were collected, tabulated and statistically analyzed. Results: Regarding the frequency of steroid induced complications, 38% were osteopenic, while 18% were osteoporotic patients. 10% had AVN. 18% had cataract. 14% had DM. There was very strong relationship between steroid duration and the frequency of DM and cataract. But in osteopenia, osteoporosis and AVN, there were weak relationship regarding steroid duration. There was very strong relationship between cumulative steroid dose and the frequency of DM, cataract, osteoporosis and AVN. There was no relationship between age and osteoporosis and AVN but in cataract and DM, there was strong relationship. There was no relationship between sex and complications (DM, cataract, osteopenia, osteoporosis and AVN). There was no relationship between disease activity (measured by SLEDAI score) and frequency of steroid complications (DM, cataract, osteopenia, osteoporosis and AVN). There was strong relationship between end organ damage (measured by SLICC damage index) and frequency of steroid complications (DM, cataract, osteoporosis and AVN). Conclusion: Steroid intake (duration and dose) were major risk factors for developing end organ damage in SLE patients.
