1/18. intestinal pseudo-obstruction in systemic lupus erythematosus: an uncommon but important clinical manifestation.OBJECTIVES: To document intestinal pseudo-obstruction (IpsO) as a recognised clinical manifestation of systemic lupus erythematosus (SLE) and a possible new clinical entity with its apparent association with ureterohydronephrosis. METHODOLOGY: We report six lupus patients who presented with IpsO and review 12 other cases from an English literature search. IpsO is defined as the presence of clinical features suggestive of intestinal obstruction but without organic obstruction, namely absence of bowel sounds, presence of multiple fluid levels on plain abdominal x-rays and exclusion of organic obstruction by imaging or surgical procedure. Other clinical characteristics related to the underlying lupus, serological and histological findings, treatment modalities and outcomes of these patients were reviewed. RESULTS: All 18 patients fulfilled the ACR revised classification criteria for SLE. None showed any clinical features of scleroderma or overlap syndrome. The mean age of onset of IpsO was 29.0 (15-47) y. The female to male ratio was 16:2. Nine patients had IpsO as the initial presentation of their underlying lupus. Coexisting lupus involvement of other organ systems included glomerulonephritis (n=7), thrombocytopenia (n=5) and cerebral lupus (n=3). The serology data and autoantibody profile of some of the previously reported patients were incomplete. In our series, anti-Ro antibody was positive in 5/6 while anti-RNP was found in 1/6 patients only. All our patients had active lupus serology at presentation. 17/18 patients required the use of high dose systemic corticosteroid therapy while one patient responded to topical adrenocorticotrophin hormone treatment. Response was good and was observed early after commencement. azathioprine was used as maintenance therapy in 6/18 patients with good effects. An apparent association with the presence of bilateral ureterohydronephrosis was found in 12/18 patients. These patients presented with dysuria without positive bacterial culture though features of chronic interstitial cystitis were not invariably found in these patients. CONCLUSION: IpsO is an uncommon but important manifestation of SLE. The underlying pathology is not fully understood but it may be related to immune complex deposition. The finding of coexisting ureterohydronephrosis suggests that there may also be a central smooth muscle motility problem of neuropathic or myogenic pathophysiology which may or may not be secondary to vasculitis. Early recognition and treatment of IpsO in SLE is important.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
2/18. Red ear(s) syndrome associated with child neuropsychiatric systemic lupus erythematosus.This case illustrates that a child having severe neuropsychiatric systemic lupus erythematosus (NPSLE) with seizure and cerebral vascular disease showed excellent clinical outcome in response to intravenous methylprednisolone and cyclophosphamide pulse, and presented unexplained red ears phenomenon.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
3/18. Alterations of cerebral glucose metabolism indicate progress to severe morphological brain lesions in neuropsychiatric systemic lupus erythematosus.Neuropsychiatric systemic lupus erythematosus (SLE) is frequently associated with deficits in brain glucose metabolism, even if morphological imaging by magnetic resonance imaging (MRI) shows no abnormalities. In these patients it is unclear whether or not the changes of brain metabolism measured by F-18-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) may progress to lesions of cerebral structure. We describe a 20-year-old woman with SLE who presented with depression, headache and impairment of memory. Initially, a cranial MRI was negative, but FDG-PET revealed significant hypometabolism in the frontal and parieto-temporo-occipital regions on both sides as well as hypermetabolism in the nuclei caudati. Within two months the patient developed an acute confusional state, seizures, visual disturbances and cranial MRI became positive showing hyperintensities at the basal ganglia and the temporo-occipital regions. Focal cerebral symptoms responded to treatment with high dose corticosteroids and brain lesions in MRI disappeared. However, a second FDG-PET showed persistent hypometabolism at frontal regions in accordance with the persistence of subclinical depression. To our knowledge, this is the first SLE case report showing that functional brain lesions visualized by FDG-PET may be a risk factor for subsequent structural brain damage seen in MRI. Thus, FDG-PET may help to verify cerebral involvement of SLE earlier than MRI.- - - - - - - - - - ranking = 7.4541913559855keywords = cerebral, brain (Clic here for more details about this article) |
4/18. Selective involvement of the choroid plexus on cerebral magnetic resonance images: a new radiological sign in patients with systemic lupus erythematosus with neurological symptoms.The selective involvement of the choroid plexus on brain magnetic resonance (MR) images is described in 2 patients with systemic lupus erythematosus presenting with neurological symptoms. The decrease in choroid plexus abnormalities on followup MR examination paralleled the clinical recovery with glucocorticoid therapy in both patients. Our cases indicate that selective involvement of the choroid plexus should be included in the spectrum of the radiological signs for neurological lupus.- - - - - - - - - - ranking = 4.0504657062206keywords = cerebral, brain (Clic here for more details about this article) |
5/18. Reversible parkinsonism in systemic lupus erythematosus.Parkinsonism as a manifestation of central nervous system (CNS) lupus is extremely rare. We report the first patient with systemic lupus erythematosus (SLE) who developed a reversible parkinsonian syndrome associated with enhancing subcortical lesions on magnetic resonance imaging (MRI). Following treatment with prednisolone and cyclophosphamide, her bradyphrenia, bradykinesia, hypophonia, rigidity, and abnormal gait progressively improved. Three months after she commenced treatment, repeat MRI scanning demonstrated resolution of the abnormal subcortical white matter enhancement. Our case illustrates unusual clinico-radiologic correlates of reversible parkinsonism in a SLE patient; these findings suggest that disruption of the subcortical frontal pathways may be a possible pathophysiologic mechanism for parkinsonism in cerebral lupus.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
6/18. Sustained normalization of cerebral blood-flow after iloprost therapy in a patient with neuropsychiatric systemic lupus erythematosus.We report the case of a 30-year-old caucasian woman affected by SLE who developed neurological symptoms (prosopagnosia and visual-spatial agnosia) after nine years of disease. brain MRI showed no abnormalities while a brain SPECT scan showed diffuse uptake defects and hypoperfusion areas in the right and left frontal-parietal regions. At that time the patient was on hydroxychloroquine (400 mg/day) and oral prednisolone (0.5 mg/kg/day) as maintenance therapy. One year later the patient showed worsening of Raynaud's phenomenon with digital dystrophic lesions and was therefore treated with an intravenous infusion of iloprost (1.5 ng/kg/min per 6h/day for 10 days consecutively), while baseline treatment remained unchanged. One month later the patient showed a dramatic improvement in her cognitive function and subsequent SPECT scans showed the gradual disappearance of perfusion abnormalities. This first report of iloprost treatment in CNS lupus suggests the potential therapeutic usefulness of this drug in patients with SLE and functional CNS involvement.- - - - - - - - - - ranking = 4.0504657062206keywords = cerebral, brain (Clic here for more details about this article) |
7/18. Neuropsychiatric systemic lupus erythematosus presenting as amyotrophic lateral sclerosis.A 61-year-old woman with a history of photosensitive dermatitis and recurrent mouth ulcers presented with progressive weakness typical of amyotrophic lateral sclerosis (ALS), and subsequently underwent extensive neurologic and rheumatologic testing. We investigated whether ALS-like motor neuron disease associated with a positive antinuclear antibody (ANA) is really ALS or rather neuropsychiatric systemic lupus erythematosus (NPSLE). On neurologic evaluation, she had prominent bulbar involvement with dysarthria and dysphagia associated with profound lingual fasciculations and a denervating pattern on electromyogram. MRI showed no evidence of cerebral ischemia. Laboratory studies revealed a positive ANA (1:2560 titer), positive antiphospholipid antibodies (GPL and MPL), circulating lupus anticoagulant, and depressed C3 and C4. Repeat MRI studies at 4 and 11 mo revealed an evolving infarct in the paramedian pons consistent with the presence of NPSLE. Therapy was initiated with corticosteroids and intravenous cyclophosphamide, and the neurologic condition did not improve, but also did not progress inexorably as would be expected with ALS. NPSLE, presumably through the mechanism of ischemic vasculopathy, may present as motor neuron disease clinically indistinguishable from ALS.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
8/18. Reversible parkinsonian syndrome in systemic and brain vasculitis.A young female patient with chronic renal failure due to a systemic vasculitis and a parkinsonian syndrome secondary to brain vasculitis, most likely systemic lupus erythematosus, is described. The patient had a dramatic response to a pulse of methylprednisolone, with remission of her parkinsonian symptoms.- - - - - - - - - - ranking = 0.25232853110304keywords = brain (Clic here for more details about this article) |
9/18. Juvenile parkinsonism as a manifestation of systemic lupus erythematosus: case report and review of the literature.Involvement of the central nervous system in systemic lupus erythematosus (SLE) has been well described. It usually includes psychiatric disturbance, seizures, and cranial nerve disorders. movement disorders are less common, chorea being the one most frequently described. A parkinsonian syndrome may be an extremely rare manifestation of cerebral lupus. We report on a case of juvenile parkinsonism as a manifestation of SLE and review the literature.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
10/18. central nervous system involvement in neonatal lupus erythematosus.Computerized tomography (CT) of the brain was performed in 10 of 11 consecutive infants with neonatal lupus erythematosus (NLE) (five boys and six girls). Ten of the 11 infants had brain neurosonography. Nine of 10 infants had abnormal CT scans. There was diffuse, markedly reduced attenuation of the cerebral white matter in four infants studied in the first week of life, and also in an infant 5 weeks of age. Patchy reduced subcortical white matter attenuation was observed in another 5-week-old infant. basal ganglia calcifications were present in two infants at 2 months of age, one of whom also had mild ventriculomegaly. A patient with macrocephaly studied at 4 months of age had enlarged ventricles and subarachnoid spaces consistent with benign macrocephaly of infancy. Cerebral ultrasound examination was abnormal in all five infants studied in the first week of life and in one infant at 2 months of age. Findings included subependymal cysts (4), echogenic white matter (3), and echogenic lenticulostriate vessels (3). Apart from one case of macrocephaly, there was no clinical evidence of neurologic disease and the subsequent development of these infants has been normal. Subclinical central nervous system (CNS) disease in NLE is likely to be a transient phenomenon that resolves as maternal antibodies are cleared from the infant's circulation. It is important to be aware of these neuroimaging abnormalities to avoid misdiagnosis of congenital viral infection in a newborn with multisystem NLE. The potential for neurologic sequelae is uncertain.- - - - - - - - - - ranking = 1.1009314124412keywords = cerebral, brain (Clic here for more details about this article) |
