Аннотация
OBJECTIVES: Systemic lupus erythematosus (SLE) is a chronic autoimmune multi-systemic disorder of the connective tissue, characterized mainly by involvement of the skin, joints, kidneys, and serosal membranes. It affects females particularly at childbearing age more commonly than males. Lupus nephritis affects around half of patients with SLE. Data about SLE and lupus nephritis in Saudi Arabia are still scarce. In this study, we aimed to evaluate the prevalence, clinical and laboratory findings of SLE and different histological types of lupus nephritis among Saudi patients at King Fahad Medical City.
METHODS: This is a retrospective study for adult patients who have been evaluated at king Fahad medical city between 2014 and 2019 and fulfilled the Systemic Lupus International Collaborating Clinics classification criteria (SLICC).
RESULTS: 112 patients, 103 (92%) females and 9 (8%) males, with confirmed diagnoses of SLE were reviewed. Skin rash (69.6%), photosensitivity (61.6%), mucosal ulcerations (45.9%), arthralgia and/or arthritis (44.6%) are the most common clinical features. Ninety seven (86.6%) out of 112 patients had a recorded first visit 24 hour urine protein level, out of those only 26 (23.2) patients presented with significant proteinuria of more than 0.5grams per day. Forty four (39.2%) have undergone kidney biopsy. Class IV and III lupus nephritis are the most common reported biopsy results (43.18% and 27.28% respectively). During the study period, three patients (2.7%) developed end-stage kidney disease requiring dialysis and five (4.5%) had renal transplant.
CONCLUSION: Our study provided insight on the demographics, characteristics and presentation of SLE patients and the outcome of lupus nephritis in Saudi Arabia.
