ABSTRACT The cause of neurologic (N) and psychiatric (P) syndromes in patients with systemic lupus erythematosus (SLE) is mutifactorial and includes primary immunopathogenic mechanisms, nonspecific sequelae of chronic disease, and concurrent illnesses. We compared the prevalence, diversity, and clinical significance of NP syndromes in patients with SLE and rheumatoid arthritis (RA).
Fifty-three patients with SLE were matched by age and sex to 53 patients with RA attending ambulatory clinics in a single academic medical center. All fulfilled the American College of Rheumatology (ACR) classification criteria for either SLE or RA. Cumulative NP manifestations were determined using the ACR nomenclature and case definitions for 19 NP syndromes. Depression and anxiety were measured by the Hospital Anxiety and Depression Scales (HADS) and symptoms of cognitive dysfunction were assessed by the Cognitive Symptoms Inventory (CSI). Health related quality of life (HRQOL) was evaluated by the SF-36 and fatigue by a 10 point Likert scale.
The patients were well matched with regard to age, sex, disease duration, and years of education. There were no significant differences in self-reported HRQOL, fatigue, anxiety, depression, and cognitive symptoms between the 2 groups. The proportion of patients with cumulative NP events was higher in RA than in SLE patients (47% vs 28%; p = 0.045), and of these the occurrence of multiple NP events in individual patients was comparable in both groups (SLE 53%; RA 48%; p = 0.75). Fifty-five percent and 66% of NP events occurred prior to the diagnosis of SLE and RA, respectively. NP events common to both SLE and RA patients were headaches, mood disorders, acute confusional states, anxiety, cerebrovascular disease, and cognitive dysfunction. Seizures and demyelinating syndrome occurred only in SLE patients, but were rare. Depression scores (HADS) were significantly higher in SLE patients with a history of cumulative NP events compared to RA patients with NP events (p = 0.02). Similarly, symptoms of cognitive dysfunction (CSI) were more common in SLE patients with a history of NP manifestations (p = 0.02). However, there were no significant differences in SF-36 subscale or fatigue scores between SLE and RA patients with cumulative NP events.
NP syndromes, regardless of etiology, are common in both SLE and RA patients. SLE patients with NP syndromes report more symptoms of depression and cognitive dysfunction compared to RA patients with NP syndromes, but do not report significantly poorer HRQOL. These results emphasize the presence of non-disease-specific causes of NP manifestations in SLE patients, which should be acknowledged in future studies of pathogenesis and treatment.

    ABSTRACT: To determine the prevalence of anxiety and depression among patients with familial Mediterranean fever (FMF) living in Germany or Turkey a prospective study was conducted. Forty FMF patients living in Turkey (T), 40 FMF patients living in Germany (G) and 40 healthy controls living in Germany (C) were included. Patients and controls were of Turkish ancestry. G were compared to T and C. The Hospital Anxiety and Depression Scale (HADS) was used with a cut-off of ≥ 8 for each subdomain score (HADS-A, HADS-D). Baseline characteristics of G were comparable to T and C except for age (T: 30.5 years, G: 35.2 years, C: 34.6 years; T vs. G P = 0.045), duration of disease (T: 14.4 years, G: 24; P < 0.001), C-reactive protein (T: 0.78 mg/dL, G: 0.78 mg/dL, C: 0.35 mg/dL; G vs. C P = 0.03). Prevalence of anxiety was higher in G compared to C (T: 65%, G: 52.5%, C: 22.5%: G vs. C P < 0.05). No difference was found for the prevalence of depression (T: 30%, G: 35%, C: 20%). The association between FMF and anxiety in subjects living in Germany persisted after adjusting for age and gender in a regression analysis and was robust to an adjustment for coexisting depression. Anxiety and depression did not correlate with FMF disease severity assessed with the Pras score. Anxiety, but not depression is more common among FMF patients living in Germany compared to healthy controls. No significant difference could be found between FMF patients living in Germany or Turkey concerning the prevalence of anxiety or depression.

    ABSTRACT: The aim of this study was to determine whether Libman-Sacks endocarditis is a pathogenic factor for cerebrovascular disease (CVD) in systemic lupus erythematosus (SLE). A cardioembolic pathogenesis of SLE CVD manifested as: 1) neuropsychiatric systemic lupus erythematosus (NPSLE), including stroke and transient ischemic attacks (TIA); 2) neurocognitive dysfunction; and 3) magnetic resonance imaging of focal brain lesions has not been established. A 6-year study of 30 patients with acute NPSLE (27 women, 38 ± 12 years of age), 46 age- and sex-matched SLE controls without NPSLE (42 women, 36 ± 12 years of age), and 26 age- and sex-matched healthy controls (22 women, 34 ± 11 years of age) who underwent clinical and laboratory evaluations, transesophageal echocardiography, carotid duplex ultrasound, transcranial Doppler ultrasound, neurocognitive testing, and brain magnetic resonance imaging/magnetic resonance angiography. Patients with NPSLE were re-evaluated after 4.5 months of therapy. All patients were followed clinically for a median of 52 months. Libman-Sacks vegetations (87%), cerebromicroembolism (27% with 2.5 times more events per hour), neurocognitive dysfunction (60%), and cerebral infarcts (47%) were more common in NPSLE than in SLE (28%, 20%, 33%, and 0%) and healthy controls (8%, 0%, 4%, and 0%, respectively) (all p ≤ 0.009). Patients with vegetations had 3 times more cerebromicroemboli per hour, lower cerebral blood flow, more strokes/TIA and overall NPSLE events, neurocognitive dysfunction, cerebral infarcts, and brain lesion load than those without (all p ≤ 0.01). Libman-Sacks vegetations were independent risk factors of NPSLE (odds ratio [OR]: 13.4; p < 0.001), neurocognitive dysfunction (OR: 8.0; p = 0.01), brain lesions (OR: 5.6; p = 0.004), and all 3 outcomes combined (OR: 7.5; p < 0.001). Follow-up re-evaluations in 18 of 23 (78%) surviving patients with NPSLE demonstrated improvement of vegetations, microembolism, brain perfusion, neurocognitive dysfunction, and lesion load (all p ≤ 0.04). Finally, patients with vegetations had reduced event-free survival time to stroke/TIA, cognitive disability, or death (p = 0.007). The presence of Libman-Sacks endocarditis in patients with SLE was associated with a higher risk for embolic CVD. This suggests that Libman-Sacks endocarditis may be a source of cerebral emboli.

    ABSTRACT: Introduction: Systemic lupus erythematosus (SLE) may present neuro-psychiatric manifestations as psychosis, seizures, mood disorder and chronic headache. This study aimed to describe the prevalence of depression and its characteristics in patients with SLE, followed in a reference center in Bahia. Material and methods: Patient with diagnosis of SLE based on the American College of Rheumatology criteria and attending the Lupus Clinic at Hospital Santa Izabel were studied. The patients were submitted to a structuralized interview and to the "PRIME-MD”. Results: Ninety nine SLE patients, being 98 female, mean age 41.1±11.8 years (range 18 to 65) were included in this study. The prevalence of depression found was 61.6% (61 cases), with major depression observed in 42 cases (42.4%), minor depression in 10 cases (10.1%) and dysthymia in 39 cases (39.3%). It was observed that many patients had more than one type of depression. Thirty eight cases (38.3%) had no depression. Conclusion: The high frequency of depression in SLE observed in the present study suggests that more attention should be given to this particular complication of the disease aiming to establish better strategies for the treatment and improve the quality of life of the patient.
