Systemic Lupus Erythematosus Patients in the Qassim Region, Saudi Arabia: Insights on Peripheral Nervous System Involvements

Abstract

Background: Systemic lupus erythematosus (SLE) is a complex autoimmune disorder with diverse clinical manifestations. This study aimed to investigate the prevalence, clinical features, and risk factors associated with peripheral nervous system (PNS) involvement in SLE patients. Materials and Methods: This study encompassed a retrospective analysis involving 377 SLE patients diagnosed according to the European Alliance of Associations for Rheumatology/American College of Rheumatology criteria at Qassim region in Saudi Arabia, conducted through a meticulous chart review facilitated by proficient data collectors. A structured data collection form/checklist, incorporating explicit definitions and instructions, was utilized for extracting information from patient files, papers, and databases. Additionally, the SLE Quality of Life Questionnaire was employed to evaluate the quality of life among the participants. A multivariate logistic regression model was employed to identify independent predictors of PNS involvement. Results: Distinct clinical patterns were observed in SLE patients with PNS involvement, including a higher prevalence of nonscarring alopecia, acute cutaneous lesions, oral ulcers, and seizures. Diabetes and chronic kidney disease emerged as significant positive predictors for PNS complications. Hematological abnormalities, renal involvement, and vitamin deficiencies were prevalent, contributing to an overall poor quality of life among these patients. Conclusion: This study underscores the need for heightened clinical awareness of PNS complications in SLE, emphasizing the impact of diabetes and chronic kidney disease as significant risk factors. Early detection and targeted interventions are crucial to improving outcomes and enhancing the overall quality of life for SLE patients with PNS involvement.
