Electroencephalography in systemic lupus erythematosus patients with neuropsychiatric manifestations

Headaches in SLE patients: a cross-sectional analysis of clinical, immunological, and Radiological Correlations

BACKGROUND

Systemic Lupus Erythematosus (SLE) is a multifaceted autoimmune disorder characterized by diverse clinical manifestations, including a significant prevalence of headaches. This cross-sectional study aimed to thoroughly explore the relationship between SLE and headaches by analysing their prevalence, types, and associated clinical, immunological, and radiological factors.

METHOD

A comparative analysis was conducted on 179 SLE patients, who were categorized into two groups: those with headaches and those without. Data collection encompassed demographic details, disease activity levels, neurological assessments, immunological profiles, and brain imaging results. Headaches were diagnosed and classified following the International Classification of Headache Disorders (ICHD-3). Disease activity was measured using the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Statistical analyses were performed to identify significant associations and correlations.

RESULTS

Headaches were observed in 55% of the SLE patients, predominantly presenting as tension-type headaches (65%) and migraines (27%). Notably, no patients met the criteria for a lupus-specific headache. The Headache Group exhibited significantly higher disease activity (SLEDAI scores). Tension-type and migraine headaches were particularly associated with increased muco-cutaneous manifestations. The presence of antiphospholipid (aPL) antibodies was significantly linked to migraines and cluster headaches. While neurological disorders such as ischemic stroke and venous sinus thrombosis were more prevalent in the Headache Group, these findings were not statistically significant. Brain MRI abnormalities were detected in 9.4% of patients with headaches, including venous sinus thrombosis (2.3%), ischemic stroke (5.8%), and white matter hyperintensities (1.1%).

CONCLUSION

This study underscore es the complex relationship between SLE and headaches, suggesting that headaches may serve as an indicator of heightened SLE disease activity. Immunological factors, particularly aPL antibodies, show a strong association with specific headache types. MRI abnormalities further emphasize the intricate neurobiological aspects in SLE patients experiencing headaches. Continued research is essential to better understand biomarkers, genetic factors, and effective treatment strategies for managing headaches in SLE patients.

Neuropsychiatric lupus erythematosus in a cohort of Egyptian patients

Background

The neuropsychiatric lupus erythematosus (NPSLE) is a severe complication of systemic lupus erythematosus (SLE) that is characterized by a variety of neurological manifestations involving both central and peripheral nervous system with variable mechanisms. This study aimed to investigate the frequency of NPSLE and its relation to other clinical and laboratory findings in SLE patients.

Results

We retrieved the medical records of 134 SLE patients during the study period; of them, 68 patients (50.7%) had NPSLE. Headache (55. 9%) was the most frequent NPSLE manifestation followed by seizures (54.4%), psychosis was the third most frequent one with a percentage of 41.2. The demographic data didn’t differ in patients with and without NPSLE. NPSLE patients had lower complement 3 (C3) (p = 0.025) and C4 (p = 0.008) levels, more lupus anticoagulant level (p = 0.033) and more frequency of antiphospholipid syndrome (p = 0.030). There was no statistical difference regarding the drug intake or other laboratory findings. Disease activity and damage indices didn’t differ in both groups.

Conclusion

The prevalence of NPSLE in this study was 50.7%. Headache, seizures and psychosis were the most frequent neuropsychiatric manifestations in the studied patients. SLE patients with neuropsychiatric manifestations had lower complement levels, higher lupus anticoagulant antibodies and antiphospholipid syndrome.

Lupus Cerebritis as the Initial Presentation of Systemic Lupus Erythematosus in a Young Female

The psychiatric and neurological symptoms of systemic lupus erythematosus (SLE) are referred to as lupus cerebritis. The wide range of symptoms associated with SLE can pose a diagnostic challenge. We present a case of lupus cerebritis in a 31-year-old female presenting with psychosis. We present this case to increase awareness of the psychiatric manifestations of SLE that can be mistaken for more common etiologies of psychosis.
