The association of psychosocial stressors and psychiatric disorders with fatigue in systemic lupus erythematosus patients.

Abstract

In systemic lupus erythematosus (SLE), fatigue is the most common and aggravating symptom which has been reported to be influenced by several factors, such as disease activity, psychosocial stressors, and psychiatric disorders. Therefore, this study aims to determine the association between disease activity, psychosocial stressors, and psychiatric disorders with fatigue in SLE patients. In this cross-sectional study, 73 female SLE patients were accepted to participate by filling out the informed consent. Besides, disease activity was divided into Lupus Low Disease Activity State (LLDAS) and non-LLDAS. The Holmes-Rahe Stress Scale and Fatigue Severity Scale (FSS) were employed to assess psychosocial stress and fatigue severity. The Mini-International Neuropsychiatric Interview (MINI) ICD-10 was used to examine psychiatric disorders. The Chi-square test was conducted to determine the association between dependent variables (fatigue) and independent variables (psychosocial stress, psychosocial stress severity, and psychiatric disorders). Out of the participants, 49 (67.1%) suffered from fatigue, and the LLDAS group contained fewer individuals than non-LLDAS, 46.6% versus 53.4%. The majority (86.3%) also experienced psychosocial stress, ranging from mild to severe, and 56 (76.7%) patients had psychiatric disorders. No significant association was discovered between SLE disease activity and fatigue. However, fatigue had significant associations with psychiatric disorders in both LLDAS (p = 0.02) and non-LLDAS groups (p = 0.04), as well as with psychosocial stress severity (p = 0.02). Histories of major personal illness (p = 0.01) and changes in eating habits (p = 0.02) were associated with fatigue among the LLDAS participants. Psychosocial stressors and psychiatric disorders were significantly associated with fatigue in SLE. Histories of major personal disease and changes in eating habits were also significantly associated with fatigue in the LLDAS participants. Therefore, early recognition of these factors is necessary to manage and prevent fatigue in SLE patients.
