Accurate identification of depression in patients with systemic lupus erythematosis (SLE) is particularly complicated because the vegetative symptoms of depression also reflect core features of this autoimmune disease. Self-reported symptoms in patients with SLE (n = 103) and community control subjects (n = 136) were examined with the British Columbia Major Depression Inventory and the Beck Depression Inventory-II. The patients with lupus obtained higher scores on most items of the former inventory. A logistic regression analysis assessed whether a subset of these items were uniquely related to group membership. Clinically significant fatigue was much more common in patients with lupus than in the control group. Two items relating to sleep disturbance also entered the equation as unique predictors. The three-variable model resulted in 85% of the control subjects and 66% of the patients being correctly classified. A subset of patients with depression, according to the Beck inventory (17 or higher), were selected (n = 41). Their most frequently endorsed symptoms on the British Columbia Inventory were fatigue (90.2%), trouble failing asleep (70.7%), cognitive difficulty (61%), and psychomotor slowing (58.5%). Only 29.3% reported significant sadness. 15% of these subjects were classified as not depressed, 46% as possibly depressed, and 39% as probably depressed on the British Columbia Inventory. It is advisable to assess whether patients are experiencing significant sadness or loss of interest before concluding that a high score on a screening test corresponds to probable depression.

Controversies in the occurrence and implications of headache in patients suffering from systemic lupus erythematosus (SLE) triggered us to conduct an extensive literature search in order to answer five clinical questions. (i) Is headache prevalence higher in SLE patients than in the general population? (ii) Is 'lupus headache' a separate entity? (iii) Is there a distinct pathogenetic mechanism of headache in SLE? (iv) Is headache related to CNS involvement or general SLE activity? (v) Is headache related to anxiety- and depression-like symptoms in SLE? All published articles reporting data from >30 SLE patients were classified into four classes (I, IIa, IIb and III) by the quality of their evidence. We found no prospective controlled study (class I), but we identified seven controlled (class II) and 28 uncontrolled studies (class III) that retrospectively investigated the occurrence of headache in SLE patients. Eight out of 35 studies applied the International Headache Society (IHS) criteria for headache classification, whereas only four uncontrolled studies investigated paediatric SLE populations (class III). Pooled data from eight studies (controlled and uncontrolled) that used the IHS criteria show that 57.1% of SLE patients reported any type of headache (migraine 31.7% and tension-type headache 23.5%). Pooled data from seven controlled studies showed that the prevalence of all headache types, including migraine, was not different from controls. Insufficient evidence was found for the concept of 'lupus headache'. No particular pathogenetic mechanism of headache in adult SLE patients has been identified, nor an association between headache and the disease status, including CNS involvement. There is no good evidence that headache is associated with anxiety and depression in SLE. Insufficient data (class III) do not allow safe conclusions for headache among paediatric SLE patients. These findings suggest that the occurrence of headache in adult SLE patients does not itself require further investigation and that headache in those patients should be classified according to IHS criteria and managed as primary headache if there is no specific indication of a role for SLE in the patient. These recommendations should be verified by a properly controlled and prospective study in both adult and paediatric populations.

Anxiety and depression of unknown etiology are frequent complications of the systemic autoimmune disease lupus erythematosus (SLE). To elucidate key pathogenic factors we study the "autoimmunity-associated behavioral syndrome" (AABS) in lupus-prone MRL-lpr mice. Based on the evidence that serum levels of the neuroactive cytokine interferon-gamma (IFN-gamma) are increased both in human and murine forms of SLE, the present study examines whether sustained IFN-gamma production in non-autoimmune mice induces deficits comparable to AABS, particularly in tasks reflective of emotional reactivity and motivated behavior. For this purpose, wild-type and IFN-gamma knockout C57BL/6J mice were infected with adenovirus carrying the cDNA for murine IFN-gamma (i.p. 2 x 10(8) pfu of virus per mouse) and shortly thereafter tested in the behavioral battery used in the detection of AABS. Serum levels of IFN-gamma were found to peak 24 h after the infection, normalized within 5 days. Although all infected animals showed reduced food/water intake and body weight, the recovery rate was slower in groups injected with IFN-gamma virus. No deficits were observed in the models of anxiety, but blunted responsiveness in the sucrose preference test (a putative model of anhedonia) lasted well beyond the IFN-gamma clearance period. These results suggest that a relatively brief elevation in systemic IFN-gamma levels impairs ingestive behavior and leads to prolonged changes in motivated behavior. As such, they are consistent with the hypothesis that upregulation in synthesis of pro-inflammatory cytokines contributes to induction of AABS and more specifically, to limbic system dysfunction during lupus-like disease.

Movement disorders are not particularly common during pregnancy, with a few exceptions. RLS occurs most commonly followed by CG. Currently, with the incidence of rheumatic fever lower than previously, any woman who develops CG should be checked for illness other than rheumatic heart disease. The differential includes systemic lupus erythromatosis and antiphospholipid antibody syndrome. Regarding the use of dopaminergic agents, the dopamine agonist, pergolide, can be maintained during pregnancy for the treatment of PD, Segawa disease, and RLS. The use of levodopa and ropinirole should be limited during pregnancy because of the possible teratogenic effects. Amantadine is contraindicated during pregnancy. The data on selegiline are controversial; animal studies show possible serotonergic effects and teratogenic effects. If treatment is indicated in patients who have Tourette syndrome, the high potency neuroleptics drugs (haloperidol) are preferred to treat associated symptoms. Depression is a common comorbidity in patients who have PD, HD,Tourette syndrome, or other chronic neurologic diseases. Depression treatment during pregnancy is covered by Levy et al elsewhere in this issue. As discussed previously, most of the data on the use of drugs during pregnancy, especially the dopaminergic agents, are limited to animal studies and case reports. Therefore, it is in part left to the neurologist to decide on treatment based on the individual patient, clinical judgment, and inferences from animal studies and limited case reports.

As a consequence of the general improvement in the diagnosis and management of rheumatic diseases, patients achieve a better quality of life, with the possibility of a normal family life including one or more pregnancies. It is important, therefore, to consider the psychological aspects of these mothers' life and the influence of their chronic disease on their children is development. Several papers have reported the impact of systemic lupus erythematosus (SLE) on the quality of life. They found higher incidence of anxiety (from 15 to 45%) and depression (from 25 to 47%) compared to the general population. We have investigated the psychological influence of SLE on family planning, and we observed that it can interfere with physiological phenomena such as parenthood and the upbringing of children. The children of lupus mothers have a normal intelligence level for their age. What is emerging, however, is an increased incidence of learning disabilities compared to the general population. This observation suggests the importance of an early neuropsychological examination, in order to identify the children needing particular care. Therefore, psychological support seems to be an important help in the counseling of patients with rheumatic disease and in the future life of their children.

Headache is common in systemic lupus erythematosus with reported prevalence as high as 70%. The aims of this study were: to estimate the prevalence and types of headache in a sample of patients with systemic lupus erythematosus comparing it with rheumatoid arthritis, to determine clinical and serological associations. Eighty-one systemic lupus erythematosus and 29 rheumatoid arthritis consecutive patients seen in our outpatient clinic were interviewed. Headache was evaluated using the diagnostic criteria proposed by the International Headache Society. Additional evaluations were carried out in the 81 systemic lupus erythematosus patients including depression, disease activity, lupus damage, function disability, quality of life, and severity degree using a validated scales. We analysed the following autoantibodies: anti-double stranded DNA, anti-nucleosomes, anti-histones, anti-ribosomal P, anti-cardiolipin antibodies, anti-beta2-glycoprotein-I (GPI), and antinuclear antibodies. Forty-one per cent of systemic lupus erythematosus and 17% of rheumatoid arthritis patients suffered from headache (P = 0.02). No significant difference for any primary headache type between the two groups was found. Frequency of headache types in systemic lupus erythematosus patients was: migraine 24%, tensional-type headache 11%, and mixed headache 5%. In systemic lupus erythematosus patients the risk factors associated with headaches were Raynaud's phenomenon (OR 3.6; 95% CI 1.3-9.5; P = 0.009) and beta2GPI antibody positivity (OR 4.5; 95% CI 1.2-16.2; p = 0.016). We conclude that headache is more common in systemic lupus erythematosus than in rheumatoid arthritis patients and was independently associated with Raynaud's phenomenon and beta2GP-I antibodies.

Neuropsychiatric lupus can be difficult to diagnose, and little prospective data exists to help direct management. In this case report we describe the acute onset of symptoms of depression, mania, and psychosis and their complete resolution 48 h following a 5-day treatment course of intravenous immunoglobulin (IVIG) in a 20-year-old woman with systemic lupus erythematosus (SLE). We review the literature on IVIG for the management of neuropsychiatric lupus. We propose that when more toxic therapies are refused or symptoms do not remit with other treatments, IVIG should be considered in patients with neuropsychiatric lupus.

The (NZBxNZW) F(1) mouse develops a spontaneous autoimmune disease process with striking similarities to human systemic lupus erythematosus (SLE). In female (NZBxNZW) F(1) mice, the production of IgG antinuclear antibodies, including antibodies to double-stranded DNA (dsDNA), is associated with the development of a severe immune complex-mediated glomerulonephritis that results in death from renal failure in virtually all animals by 12 months of age. Since B-1 and marginal zone (MZ) cells represent a potential source of pathogenic antibodies and because B cell superantigens have been demonstrated to reduce B-1 and MZ cells in vivo, we tested the effect of repeated injections of the superantigen protein A (SpA) from S. aureus on the disease of this lupus model. We found that weekly intraperitoneal injections of SpA delay the progression of serum anti-DNA IgG and reduce proteinuria early in young female (NZBxNZW) F(1) mice. This superantigen also induced a specific depression in the numbers of peritoneal B-1 cells, as compared to mice treated with a control protein. These results support the role of B-1 cells in the development of the autoimmune disease in this mouse model and suggest that B cell superantigens may be useful in the management of autoimmune conditions.

Despite recent advances, patients with systemic lupus erythematosus (SLE) still experience considerable morbidity and mortality. To try and improve their prognosis, varied novel biological interventions and immune manipulations are being developed. They may hold promise in particular for patients whose disease is organ-threatening and refractory to conventional treatment. In addition, awareness of the tendency of lupus patients to develop accelerated atherosclerosis as well as newly gained insights into the underlying mechanisms, may lead to better control of risk factors, earlier diagnosis of prevalent cardiovascular disease and more effective treatment. Infections also remain a significant threat that may be amenable to improved preventive measures. Evidence related to a better management of lupus patients by specialists, the need to address the impact of commonly associated stress and depression and other significant developments are also presented and discussed.

Endothelial function, measured noninvasively by brachial artery flow-mediated dilatation (FMD), has been shown to be impaired in patients with systemic lupus erythematosus (SLE). We hypothesized that depressed FMD in SLE patients is associated with increased levels of plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis and regulator of vasoactivity. In this cross-sectional study of female SLE patients under the age of 55, putative markers of cardiovascular disease (CVD) such as PAI-1 were measured in addition to lupus-related disease activity (SLEDAI). The primary outcome, FMD, was measured using high-resolution ultrasound of the brachial artery gated to the R wave to determine endothelial-dependent vasomotion. Endothelial-independent vasomotion was measured in response to nitroglycerin (NMD). Seventy-six female SLE patients, mean age 38.3 +/- 9.4 years, were included. All patients demonstrated normal NMD responses, indicating that depression of FMD was related to decreased endothelial nitric oxide production. Increased PAI-1 was related to depressed FMD by univariate regression (P = 0.004). In a multivariable regression model adjusting for t-PA (tissue plasminogen activator)/PAI-1 ratio, SLEDAI, age at visit, family history of cardiovascular disease, SLE disease duration and body mass index, every 1 ng/mL increase in PAI-1 was associated with a reduction of 0.07 units FMD (P = 0.039). PAI-1 was associated with impaired endothelial dysfunction, after controlling for several potential confounders. Given the high incidence of cardiovascular disease in SLE, further investigation of the role of subclinical markers of CVD is needed.
