A woman aged 22 years with a history of lupus presented in the 18th week of pregnancy with hypertensive emergency and flash pulmonary oedema. Bedside echocardiogram revealed severe left ventricular (LV) dysfunction with an ejection fraction (EF) of 25% and pericardial effusion. Laboratories revealed hypocomplementemia, proteinuria, elevated C reactive protein and anti-DS-DNA, raising concern for a lupus flare. Cardiac MRI showed an acute intramyocardial oedematous process, consistent with lupus carditis, and further worsening of LVEF to 13%...

OBJECTIVE: Standardized cognitive tests and functional magnetic resonance imaging (fMRI) studies of SLE patients demonstrate deficits in working memory and executive function. These neurobehavioral abnormalities are not well studied in antiphospholipid syndrome (APS), which may occur independently of or together with SLE. This study compares an fMRI paradigm involving motor, working memory and executive function in SLE patients without antiphospholipid antibody (SLE), aPL-positive non-SLE patients (aPL+), and controls...

The diagnosis and pathology of neuropsychiatric systemic lupus erythematosus (NPSLE) remains challenging. Herein, we used multimodal imaging to assess anatomical and functional changes in brains of SLE patients instead of a single MRI approach generally used in previous studies. Twenty-two NPSLE patients, 21 non-NPSLE patients and 20 healthy controls (HCs) underwent 3.0 T MRI with multivoxel magnetic resonance spectroscopy, T1-weighted volumetric images for voxel based morphometry (VBM) and diffusional kurtosis imaging (DKI) scans...

Involvement of the respiratory system is common in connective tissue diseases (CTDs), and the resultant lung injury can affect every part of the lung: the pleura, alveoli, interstitium, vasculature, lymphatic tissue, and large and/or small airways. Most of the parenchymal manifestations of CTD are similar to those found in interstitial lung diseases (ILDs), especially idiopathic interstitial pneumonias, and can be classified using the same system. Although there is some overlap, each CTD is associated with a characteristic pattern of pulmonary involvement...

Jaccoud's arthropathy (JA) is a clinical situation nowadays present mostly in systemic lupus erythematosus (SLE). It is characterized by the presence of joint deformities such as "swan neck," ulnar deviation and "Z-thumb" resembling rheumatoid arthritis (RA) but that are passively correctable and without bone erosion on plain radiographs. From our cohort of SLE patients with JA, we selected a subgroup with a more severe form of this arthropathy and looked at their clinical and laboratory profile as well as studied the magnetic resonance imaging (MRI) findings or ultrasound (US) obtained from the hand with most evident deformities...

BACKGROUND: The genesis of severe fatigue and disability in people following acute pathogen invasion involves the activation of Toll-like receptors followed by the upregulation of proinflammatory cytokines and the activation of microglia and astrocytes. Many patients suffering from neuroinflammatory and autoimmune diseases, such as multiple sclerosis, Parkinson's disease and systemic lupus erythematosus, also commonly suffer from severe disabling fatigue. Such patients also present with chronic peripheral immune activation and systemic inflammation in the guise of elevated proinflammtory cytokines, oxidative stress and activated Toll-like receptors...

A 36-year-old woman who had received long-term treatment with chloroquine for systemic lupus erythematosus developed a third degree atrioventricular block and required a permanent pacemaker. Notably, left ventricular thickening and mild systolic dysfunction were noticed on echocardiography as well as on cardiac MRI. As there was no clear explanation for myocardial findings, the patient underwent an endomyocardial biopsy that demonstrated vacuolar degeneration of myocytes on light microscopy and curvilinear bodies on electron microscopy, both findings consistent with chloroquine toxicity...
