Transverse Myelitis Affecting More Than 4 Spinal Segments Associated with Systemic Lupus Erythematosus: Clinical, Immunological, and Radiological Characteristics of 22 Patients

Severe Spinal Cord Inflammation in a Young Woman Diagnosed With Systemic Lupus Erythematosus: A Case Study

We describe a case of longitudinally extensive transverse myelitis (LETM), an uncommon and dangerous complication of systemic lupus erythematosus (SLE) that struck a 22-year-old woman with SLE. Chronic autoimmune illness (e.g., SLE) affects the skin, kidneys, joints, blood, and neurological system, among other organs. LETM is a condition where the spinal cord becomes inflamed and damaged, causing neurological problems, such as weakness, sensory loss, and bladder dysfunction. The patient presented with abdominal pain, vomiting, body aches, and fatigue, followed by shock, hypoxia, urinary retention, and constipation. Moreover, she had severe and asymmetric weakness, sensory loss, and areflexia in her limbs. She was diagnosed with LETM based on a nerve conduction study and MRI of the spine, which showed a motor neuron disease pattern and T2 hyperintense signals throughout the spinal cord gray and white matter. She responded well to immunoglobulins, plasma exchange, and high-dose steroids as treatment. Although her prognosis is favorable, there might be some lingering neurological issues or limitations. This instance highlights the significance of treating individuals with SLE as soon as possible after developing LETM.

The Role of MRI in Differentiating Demyelinating and Inflammatory (not Infectious) Myelopathies

Demyelinating and inflammatory myelopathies represent a group of diseases with characteristic patterns in neuroimaging and several differential diagnoses. The main imaging patterns of demyelinating myelopathies (multiple sclerosis, neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis, and myelin oligodendrocyte glycoprotein antibody-related disorder) and inflammatory myelopathies (systemic lupus erythematosus-myelitis, sarcoidosis-myelitis, Sjögren-myelitis, and Behçet's-myelitis) will be discussed in this article, highlighting key points to the differential diagnosis.

Exploring the risk factors and prognosis of transverse myelitis in systemic lupus erythematosus

Purpose:

We aimed to describe the clinical characteristics and outcomes of patients with transverse myelitis (TM) as a rare manifestation in systemic lupus erythematosus (SLE) and explore the risk factors and prognosis of SLE-related TM (SLE-TM).

Methods:

We conducted a retrospective case–control and cohort analysis. All patients with SLE-TM (58 patients) and 232 with SLE without TM, as a control group, were admitted to Peking Union Medical College Hospital between January 1993 and May 2021. Factors associated with the presence of SLE-TM and its prognosis were assessed using logistic regression and Cox proportional hazard models.

Results:

Multivariate analysis revealed that positive anti-Ro/Sjogren’s syndrome A (anti-Ro/ SSA) (<0.01) and increased erythrocyte sedimentation rate (ESR) (p < 0.01) were associated with SLE-TM. Regarding prognosis, methylprednisolone (MP) pulse therapy within 2 weeks of onset (adjusted hazard ratio (AHR), 2.12; 95% confidence interval (CI), 1.06–4.23; p = 0.03) was associated with short-term neurological improvement. An American Spinal Injury Association Impairment Scale (AIS) grades of A, B, or C at onset (AHR, 0.12; 95% CI 0.05–0.28; p < 0.001) and hypoglycorrhachia (AHR, 0.29; 95% CI, 0.13–0.65; p < 0.01) were associated with a short-term non-improved outcome.

Conclusions:

The positive anti-Ro/SSA antibodies and increased ESR may be associated with the presence of SLE-TM. An initial presentation with severe myelitis and hypoglycorrhachia appear to be predictors of a poor neurological outcome. Early steroid pulse therapy may improve the prognosis.

Immunological parameters of recurrent miscarriages among women in Thi-Qar province

Recurrent miscarriage (RM) is defined as the loss of pregnancy three or more consecutive times in the first and second trimester, which in some cases occurs due to immune abnormalities. This study aimed to assess some immunological parameters in women with recurrent miscarriages, including the level of antiphospholipid antibody (APA), anticardiolipin (ACA), antinuclear antibody (ANA), complement C3 and C4, and interleukine-3 (IL-3). We included 100 patients together with 100 healthy women as a control. ELIZA was used to measure some types of autoantibodies. APA and ACA significantly increased (P≤0.05) in patients compared to control. In addition, 29% of the patients were positive for antinuclear antibodies (ANA), while the control subjects had negative results for these autoantibodies. Regarding the complement, the serum levels of C3 and C4 were significantly elevated in the serum level of patients when compared to the control group, but in treated patients (heparin and low-dose aspirin), the levels of the complement (C3 and C4) showed a significant decrease in patients compared to total controls. Cytokine level (IL-3) significantly decreased in untreated patients 302.78 pg/ml compared to treated patients (741.57 pg/ml). Antiphospholipid antibodies are more prevalent among women with recurrent miscarriages and are also believed to be the result of abnormal autoimmune activation.

Transverse myelitis in systemic lupus erythematosus: A case report and systematic literature review

OBJECTIVE

Acute transverse myelitis (TM) is a rare complication secondary to systemic lupus erythematosus (SLE) that can cause patients' extensive and severe neuropsychiatric disorders. Due to the rarity of the onset of acute TM, there is still no standard treatment protocol. This study was to summarize the clinical features of SLE-TM through a case report and systematic review.

METHODS

We report a case of acute TM with the initial symptoms of headache and fever on admission to hospital, with lesions in medulla oblongata, cervical medulla, and thoracic medulla. Furthermore, all cases of SLE combined with acute TM from January 1975 to February 2022 were concluded and reviewed to compare the disease's current treatment strategies and prognosis.

RESULTS

Patients with SLE-TM are mainly female (97.65%), with an average age of 36.89, a TM incidence of 24.51% and a longitudinal myelitis (LM) incidence of 67.76%. In addition, 68.63% of patients present an increased albumin, and only 16.50% of patients could recover. 32.35% of patients showed positive anti-cardiolipin antibody. Moreover, the patients who could recover are generally younger than those in the improved and paraparesis groups. After classifying the statistical results twice according to magnetic resonance imaging results and prognosis respectively, the erythrocyte sedimentation rate (ESR) in LM group was significantly higher than that in the other two groups. The positive rate of anti-DNA and anti-cardiolipin antibody (ANCL) in TM group was significantly higher than that of the other groups. According to the prognostic grouping, ESR in the recovery group was significantly higher than those in the other two groups. The positive ANCL in the poor prognosis group was slightly higher than that in the other two groups.

CONCLUSION

We offer a novel insight for this rare disease and hope to bring some inspiration the basic research for SLE-TM.

Uncommon inflammatory/immune-related myelopathies

The differential diagnosis for immune-mediated myelopathies is broad. Although clinical manifestations overlap, certain presentations are suggestive of a particular myelopathy etiology. Spine MRI lesion characteristics including the length and location, and the pattern of gadolinium enhancement, help narrow the differential diagnosis and exclude an extrinsic compressive cause. The discovery of specific antibodies that serve as biomarkers of myelitis such as aquaporin-4-IgG and myelin-oligodendrocyte -glycoprotein-IgG (MOG-IgG), has improved our understanding of myelitis pathophysiology and facilitated diagnosis. In this review we will focus on the pathophysiology, clinical presentation, imaging findings and treatment and outcomes of uncommon immune-mediated myelopathies.

Relapse rates and risk factors for unfavorable neurological prognosis of transverse myelitis in systemic lupus erythematosus: A systematic review and meta-analysis

BACKGROUND

Transverse myelitis (TM) is a rare but severe systemic lupus erythematosus (SLE) manifestation. To date, the prognostic factors for SLE-associated TM have been far less well-studied. There are also controversial data on the association of antiphospholipid antibodies (aPLs), Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score, longitudinal extensive transverse myelitis (LETM), and decreased complement levels with the outcome of TM. We aimed to review the potential prognostic factors and integrate relapse rates of observational studies for SLE-associated TM.

METHOD

To review the prognosis for SLE-associated TM, relevant articles published up to July 30, 2021, were comprehensively and systematically identified from PubMed, EMBASE and Web of Science databases. Five studies encompassing 283 patients with SLE-related TM were included in this meta-analysis; raw data were obtained from three studies.

RESULTS

The risk factors for unfavorable neurological outcome included demographic features, clinical characteristics, laboratory data, among which a grade of A, B or C on the American Spinal Injury Association Impairment Scale (AIS) at the onset of TM was associated with poor prognosis (OR: 56.05, 95% CI: 6.29-499.25, P < 0.001). The presence of hypoglycorrhachia was also correlated with a worse prognosis (OR: 10.78, 95% CI: 3.74-31.07, P < 0.001). No noticeable correlation was revealed between a poor outcome and positive aPLs and different aPLs profiles (anticardiolipin antibody [aCL], anti-β2-glycoprotein I (anti-β2GPI], lupus anticoagulant [LA]). The pooled 1-, 3- and 5-year relapse rates were 22% (95% CI: 0.13-0.31), 34% (95% CI: 0.22-0.47) and 36% (95% CI: 0.14-0.58), respectively. No significant publication bias was found.

CONCLUSION

A grade of A, B, or C on the AIS at initial TM and the presence of hypoglycorrhachia were found to be related to a worse prognosis in patients with SLE-associated TM. Notably, aPLs and different aPLs profiles may not suggest poor neurological outcome. The long-term relapse rate of patients with SLE-associated TM was relatively high. We recommend that treatment be stratified based on the initial severity of myelitis. For patients with severe myelitis, early intensive therapy may be initiated as soon as possible.

Transverse Myelitis in Systemic Lupus Erythematosus: Clinical Features and Prognostic Factors in a Large Cohort of Latin American Patients

BACKGROUND

Acute transverse myelitis (ATM) is an infrequent but severe complication of systemic lupus erythematosus (SLE). The purpose of study was to describe clinical features and prognostic factors of patients with SLE-related ATM.

METHODS

In this medical records review study, data were collected from 60 patients from 16 centers seen between 1996 and 2017 who met diagnostic criteria for SLE and myelitis as defined by the American College of Rheumatology/Systemic International Collaborating Clinics and the Working Group of the Transverse Myelitis Consortium, respectively. Objective neurological impairment was measured with American Spinal Injury Association Impairment Scale (AIS) and European Database for Multiple Sclerosis Grade Scale (EGS).

RESULTS

Among patients included, 95% (n = 57) were female, and the average age was 31.6 ± 9.6 years. Myelitis developed after diagnosis of SLE in 60% (n = 36). Symmetrical paraparesis with hypoesthesia, flaccidity, sphincter dysfunction, AIS = A/B, and EGS ≥ 8 was the most common presentation. Intravenous methylprednisolone was used in 95% (n = 57), and 78.3% (n = 47) received intravenous cyclophosphamide. Sensory/motor recovery at 6 months was observed in 75% (42 of 56), but only in 16.1% (9 of 56) was complete. Hypoglycorrhachia and EGS ≥ 7 in the nadir were associated with an unfavorable neurological outcome at 6 months (p < 0.05). A relapse rate during follow-up was observed in 30.4% (17 of 56). Hypoglycorrhachia and hypocomplementemia seem to be protective factors for relapse. Intravenous cyclophosphamide was associated with time delay to relapse.

CONCLUSIONS

Systemic lupus erythematosus-related ATM may occur at any time of SLE course, leading to significant disability despite treatment. Relapses are infrequent and intravenous cyclophosphamide seems to delay it. Hypoglycorrhachia, hypocomplementemia, and EGS at nadir are the most important prognostic factors.

Systemic lupus erythematosus presenting with holocord myelitis

This is a report of a case of a 25-year-old woman, who presented with a rapidly progressive sensory-motor flaccid quadriparesis which had developed over a few days along with bladder and bowel involvement. She had a past history of photosensitive rash and joint pains along with mild-to-moderate grade fever; for which she had never been evaluated. Serological markers for systemic lupus erythematosus (SLE) were strongly positive and helped in establishing the diagnosis of SLE-related holocord myelitis. High-dose intravenous glucocorticoid followed by intravenous pulse cyclophosphamide was used to treat her and there was a significant improvement. In this case report, the diagnosis of SLE was made for the first time in a patient presenting with holocord myelitis.

Differential diagnosis in acute inflammatory myelitis

INTRODUCTION

Establishing differential diagnosis between different inflammatory causes of acute transverse myelitis (ATM) can be difficult. The objective of this study was to see which clinical, imaging or laboratory findings best contribute to confirm ATM etiology.

METHODS

We reviewed clinical history, MRI images, CSF and serum laboratory tests in a retrospective study of patients presenting ATM. Univariate and multivariate multinomial logistic regression analysis was performed for each of the items listed above.

RESULTS

One hundred and seventy-two patients were analyzed in the study: 68 with multiple sclerosis (MS), 67 presenting idiopathic myelitis (IM; 23 of which were recurrent), 21 who developed positive systemic-antibodies associated myelitis (SAb-M) and 16 with neuromyelitis optica spectrum disorders (NMOSD). The following factors were associated with increased risk of developing MS: lower values in the modified Rankin scale at admission; positive oligoclonal bands (OCB); higher spinal cord lesion load; presence of brain demyelinating lesions; and disease recurrence. Longitudinally extended (LE) lesions, brain demyelinating lesions, and recurrences also contributed to final diagnosis of NMOSD. Multivariate multinomial logistic regression analysis showed presence of LE lesions increased risk of NMOSD and recurrence of ATM. Whereas, brain demyelinating lesions, and presence of OCB increased risk of MS.

CONCLUSIONS

ATM etiology may be clarified on the basis of spinal cord and brain MRI findings, together with CSF biochemistry and serum laboratory test results, allowing more timely and exact diagnosis as well as specific therapy for cases of uncertain origin.

Clinical features of transverse myelitis associated with systemic lupus erythematosus

Objective

This study aimed to identify the clinical characteristics and prognostic factors of systemic lupus erythematosus with transverse myelitis (SLE-TM) in a relatively large patient series.

Methods

This retrospective study considered 45 SLE-TM individuals treated as inpatients and outpatients at Peking Union Medical College Hospital between 1993 and 2018. SLE-TM patients were compared with 180 controls, and SLE-TM patients with neuromyelitis optica spectrum disorder (NMOSD) were compared to those without NMOSD.

Results

Compared to controls, the SLE-TM group frequently had a fever and had a significantly higher positive rate of anticardiolipin and lupus anticoagulant. Among the 45 patients, 22 met the NMOSD criteria. Compared to non-NMOSD patients, NMOSD patients had a lower incidence of rash ( p = 0.023), serositis ( p = 0.042) and renal disorder ( p = 0.073); a lower prevalence of decreased complement ( p = 0.083); and lower rates of positive anti-dsDNA ( p = 0.074) and anti-Sm ( p = 0.042). Among 22 SLE-TM patients with NMOSD, 18 underwent aquaporin 4 antibody testing, with 11 showing positive results. Out of the 45 patients, 39 were given methylprednisolone pulse treatment. After treatment, 32 patients had lower-limb muscle strength recovery (recovered group), whereas 13 had no change and persistent severe neurological deficits (non-recovered group). Compared to the recovered group, the non-recovered group were younger ( p = 0.002), had a higher likelihood of having a fever ( p = 0.020), initial severe myelitis ( p < 0.001), long spinal segment involvement ( p = 0.017) and higher C-reactive protein levels ( p = 0.020). Methylprednisolone pulse given within two weeks of onset was more frequent in the recovered group than in the non-recovered group ( p = 0.082).

Conclusions

Disease characteristics differed between SLE-TM patients with and without NMOSD. SLE and NMOSD tended to be co-morbidities. Initial severe neurological impairment, extensive spinal cord lesions, hyper-inflammation and delayed steroid impulse treatment could be predictors of poor outcome for SLE-TM.

Neuroinflammatory and Demyelinating Disorders of Childhood

In this chapter, we will review monophasic and recurrent demyelinating disorders in children. We will first review consensus definitions and provide an approach to the evaluation of children with first episode of acquired demyelinating disorder. We will discuss typical clinical and radiological features of these syndromes. In the second section, we will review features of recurrent demyelinating syndromes in children, focusing on clinical presentation and treatment options.

Spinal cord syndromes in patients with systemic lupus erythematosus: differentiating lupus myelitis, neuromyelitis optica, and multiple sclerosis

OBJECTIVE

Non-infectious myelitis in systemic lupus erythematosus (SLE) may be due to SLE myelitis, comorbid multiple sclerosis (MS), or neuromyelitis optica (NMO). We compared characteristics of these three conditions in SLE patients at a large academic institution.

METHODS

We searched for neurologic diagnoses of SLE myelitis, NMO myelitis, and MS myelitis among 2297 patients with at least four 1997 American College of Rheumatology revised criteria for SLE between 2000 and 2015. Each subject was reviewed by a neurologist to confirm the underlying neurologic diagnosis. Demographic, clinical, laboratory, and radiographic data were extracted and compared using Fisher's exact test, analysis of variance, and Wilcoxon rank-sum test.

RESULTS

Fifteen of the 2297 subjects with SLE (0.7%) met criteria for a spinal cord syndrome: seven had SLE myelitis, three had AQP4 seropositive NMO, and five had MS. The median SLE Disease Activity Index 2000 score at time of neurologic syndrome presentation was higher in SLE myelitis subjects (8, interquartile range (IQR) 7-16) compared with subjects with NMO (6, IQR 0-14) or MS (2, IQR 0-4), p = 0.02. Subjects with SLE myelitis were also more likely to have elevated anti-dsDNA antibodies at presentation (86%) compared with subjects with NMO (33%) or MS (0%), p = 0.03.

CONCLUSION

Myelitis occurs rarely among patients with SLE. Compared with subjects with SLE + NMO and subjects with SLE + MS, subjects with SLE myelitis had higher SLE disease activity at presentation.

Longitudinal extensive transverse myelitis: a rare neurological complication of systemic lupus erythematosus

We present a 47-year-old woman with recently diagnosed systemic lupus erythematosus who developed progressive numbness and tingling of her upper and lower extremities, followed by weakness and difficulty ambulating. She was diagnosed with longitudinal extensive transverse myelitis involving her entire cervical and thoracic spinal cord. Infectious workup was unrevealing. She failed to respond to pulse-dose intravenous steroids, but slowly improved with the addition of plasmapheresis and cyclophosphamide. Following maintenance treatment with mycophenolate mofetil and slow tapering of oral steroids, she has maintained complete remission with significant recovery of neurological function.

Magnetic resonance imaging in immune-mediated myelopathies

Immune-mediated myelopathies are a heterogeneous group of inflammatory spinal cord disorders including autoimmune disorders with known antibodies, e.g. aquaporin-4 IgG channelopathy or anti-myelin oligodendrocyte glycoprotein-associated myelitis, myelopathies in the context of multiple sclerosis and systemic autoimmune disorders with myelopathy, as well as post-infectious and paraneoplastic myelopathies. Although magnetic resonance imaging of the spinal cord is still challenging due to the small dimension of the cord cross-section and frequent movement and susceptibility artifacts, recent methodological advances have led to improved diagnostic evaluation and characterization of immune-mediated myelopathies. Topography, length and width of the lesion, gadolinium enhancement pattern, and changes in morphology over time help in narrowing the broad differential diagnosis. In this review, we give an overview of recent advances in magnetic resonance imaging of immune-mediated myelopathies and its role in the differential diagnosis and monitoring of this heterogeneous group of disorders.

Longitudinally Extensive Transverse Myelitis Associated With Systemic Lupus Erythematosus: A Case Report and Literature Review

BACKGROUND

Lupus myelitis is a rare but disastrous complication of systemic lupus erythematosus (SLE). The transverse myelitis (TM) may involve three or more contiguous spinal cord segments and as such is designated longitudinally extensive transverse myelitis (LETM). The neurological presentation may vary based on the location of the pathology and may consist of a combination of sensory and motor deficits. TM could be the presenting feature of SLE or present after 10 years of disease, while SLE was considered to be in remission.

CASE PRESENTATION

26-year-old Black man with history of biopsy proven-lupus nephritis that had progressed to ESRD, presented with sudden onset quadriplegia that resolved upon arrival to the hospital. On exam, the temperature was 101.8°F and the neurological exam was consistent with residual weakness on the left sided-upper and lower extremities. Leukopenia, lymphopenia and thrombocytopenia, along with low complements were noted. Brain MRI was normal however, the spine MRI was suspicious for an epidural process (C2-T4) and intravenous antibiotics were commenced. After five days, neurological improvement was nil and new spine MRI revealed spinal cord edema secondary to myelitis at several spinal cord levels (C2-T4). Laboratory data was consistent with a SLE flare complicated with longitudinal extensive transverse myelitis. Pulse steroids and plasma exchange were initiated. Two weeks after admission, MRI demonstrated resolution of the epidural spinal lesion and marked improvement in spinal cord edema.

CONCLUSION

TM can be the presenting feature of SLE or appear later on during the course of their disease. LETM is the most frequently type of TM found among SLE patients. Given the grave nature of the disease, it is of paramount importance that clinical features of TM be promptly recognized among SLE patients, to prevent catastrophic or even life-threatening outcomes.

From A to D: A Unique Case Report of Recovery After Longitudinal Myelitis Related to Lupus

Longitudinal myelitis secondary to an acute flare of systemic lupus erythematosus has been reported in the literature. There have been few published cases of complete functional recovery in patients with systemic lupus erythematosus-related longitudinal myelitis (systemic lupus erythematosus-related longitudinal myelitis). Of those cases, none have described in detail the rehabilitation course of treatment. In the current case, intensive rehabilitation was coupled with aggressive pharmaceutical treatment resulting in almost full functional recovery. A 23-yr-old African American woman with a history of systemic lupus erythematosus was originally admitted as an inpatient for flank pain. Overnight, she progressed rapidly to complete flaccid paraplegia classified as T3 American Spinal Injury Association Impairment Scale A based on the International Standards for Neurological Classification of Spinal Cord Injury. Throughout the next year, she participated in acute inpatient rehabilitation, followed by outpatient rehabilitation (physical, occupational, and aquatic therapies). A year after her initial hospital admission, she progressed to full community ambulation T3 American Spinal Injury Association Impairment Scale D. This case illustrates the importance of proper medical treatment and a comprehensive rehabilitation program, which improved functional outcomes for a patient with a complete spinal cord injury due to systemic lupus erythematosus-related longitudinal myelitis.

Natural history of longitudinally extensive transverse myelitis in 35 Hispanic patients with systemic lupus erythematosus: good short-term functional outcome and paradoxical increase in long-term mortality

Background and objective

Acute transverse myelitis (TM) is an infrequent neurological complication of systemic lupus erythematosus (SLE). Short-term outcome varies widely between cohorts. Little is known about the epidemiology and long-term functional outcome of TM associated to SLE.

Methods

Patients with SLE and acute TM were identified during hospital admission, visits to the Emergency Room or the Neurology Outpatient Clinic. We evaluated ambispectively those patients with SLE presenting with clinical myelopathy and corroborated with spinal MRI. Cases were divided as partial (non-paralyzing) or complete (paralyzing). We determined long-term functional outcome as well as mortality in those patients with follow-up periods of at least five years.

Results

We identified 35 patients (partial, n = 15; complete, n = 20) in which complete clinical and imaging data were available (26 with follow-up ≥ 5 years). Patients with complete TM were significantly older than those with partial forms. Positive antiphospholipid antibodies were observed in 80% of patients, suggesting a possible mechanistical role. Surprisingly, functional recovery at one year was in general good; however, we observed a five-year mortality of 31% because of sepsis (in 10 cases) or pulmonary embolism (in one case).

Conclusions

Short-term outcome of SLE-related TM is generally good, and recurrence rate is low. However, we observed a long-term fatality rate of 31% for reasons unrelated to TM, suggesting that TM is a manifestation of severe immune dysregulation and a predictor of severity and mortality in patients with SLE.

Demyelinating syndrome in SLE encompasses different subtypes: Do we need new classification criteria? Pooled results from systematic literature review and monocentric cohort analysis

OBJECTIVE

To describe features of demyelinating syndrome (DS) in systemic lupus erythematosus (SLE).

METHODS

A systematic review using a combination of Mesh terms in PubMed and a retrospective analysis of 343 adult patients with SLE were carried out to identify patients with DS. Retrieved cases were classified as affected with DS according to 1999 ACR nomenclature and attributed to SLE by applying the 2015 algorithm. DS defined according to the clinical but not temporal 1999 ACR criteria was classified as clinically isolated syndrome (CIS).

RESULTS

Estimated prevalence of DS (including CIS) in the SLE cohort was 1.3% and incidence rate was 1.5 cases per 1000 patient-years. Overall, 100 cases from literature review and 4 from SLE cohort were identified and are presented as a whole: 49 (47.1%) were classified as neuromyelitis optica spectrum disorders (NMOSD), 29 (27.9%) as CIS, 14 (13.5%) as NMO, 7 (6.7%) as DS prominently involving the brainstem and 5 (4.8%) as DS prominently involving the brain. DS was the SLE onset manifestation in 41 (39.4%) patients. Longitudinally extensive transverse myelitis was the most frequent manifestations being present in 73 (70.2%) patients (37 NMOSD, 21 CIS, 14 NMO, 1 DSB). Methylprednisolone (79.8%) and cyclophosphamide (55.8%) pulses, but also plasma-exchange (16.3%) and rituximab (7.6%) in relapsing-refractory cases, were mostly prescribed. Complete recovery rate ranged between 62% in CIS to 7% in NMO.

CONCLUSION

DS in SLE is rare (1%) and encompasses different subtypes including CIS. Timely diagnosis and early treatment are recommended to minimize complications.

The diagnosis and clinical management of the neuropsychiatric manifestations of lupus

Neuropsychiatric (NP) involvement in Systemic Lupus Erythematosus (SLE), can be a severe and troubling manifestation of the disease that heavily impacts patient's health, quality of life and disease outcome. It is one of the most complex expressions of SLE which can affect central, peripheral and autonomous nervous system. Complex interrelated pathogenetic mechanisms, including genetic factors, vasculopathy, vascular occlusion, neuroendocrine-immune imbalance, tissue and neuronal damage mediated by autoantibodies, inflammatory mediators, blood brain barrier dysfunction and direct neuronal cell death can be all involved. About NPSLE a number of issues are still matter of debate: from classification and burden of NPSLE to attribution and diagnosis. The role of neuroimaging and new methods of investigation still remain pivotal and rapidly evolving as well as is the increasing knowledge in the pathogenesis. Overall, two main pathogenetic pathways have been recognized yielding different clinical phenotypes: a predominant ischemic-vascular one involving large and small blood vessels, mediated by aPL, immune complexes and leuko-agglutination which it is manifested with more frequent focal NP clinical pictures and a predominantly inflammatory-neurotoxic one mediated by complement activation, increased permeability of the BBB, intrathecal migration of autoantibodies, local production of immune complexes and pro-inflammatory cytokines and other inflammatory mediators usually appearing as diffuse NP manifestations. In the attempt to depict a journey throughout NPSLE from diagnosis to a reasoned therapeutic approach, classification, epidemiology, attribution, risk factors, diagnostic challenges, neuroimaging techniques and pathogenesis will be considered in this narrative review based on the most relevant and recent published data.

Myelitis in systemic lupus erythematosus: clinical features, immunological profile and magnetic resonance imaging of five cases

Myelopathy is one of the neuropsychiatric lupus syndromes. In this article, an original series of related lupus myelitis is reported and analyzed. We employed a retrospective chart review and identified all patients who were admitted to a general hospital in Buenos Aires, Argentina, with SLE and myelitis during the period 2007-2014. Five patients were observed, all women. The mean age was 25.4 years (19-39). In three of five cases, myelitis was one of the initial SLE manifestations. The SLE Disease Activity Index was variable (3/5 with high activity). Time to nadir ranged from 6 to 72 h. All had severe impairment, with motor deficit, sensory level and urinary retention. Magnetic resonance imaging was abnormal in all cases, 3/5 presented a longitudinally extensive myelitis. Serum analysis revealed positive antinuclear antibodies at a high titer in all patients, 4/5 had low complement levels and 3/5 had anti-phospholipids positive. The treatment (methylprednisolone and, in some cases, cyclophosphamide, anticoagulation and/or plasmapheresis) produced partial improvement or no benefits. One patient died due to sepsis. The others showed significant disability at 6 months (European Database for Multiple Sclerosis grading scale=6-8). In view of these results, myelitis associated with lupus shows heterogeneity of the clinical, radiological and serological features. In our experience, the cases were severe and with poor response to treatment. Further studies are required to understand this disease and establish a more efficient treatment.

Myelopathy in systemic lupus erythematosus: clinical, laboratory, radiological and progression findings in a cohort of 1,193 patients

OBJECTIVE

To describe clinical, laboratory, radiological and progression characteristics of myelopathy in systemic lupus erythematosus (SLE).

PATIENTS AND METHODS

A retrospective analysis was performed on a cohort of 1193 patients with SLE (ACR criteria) in order to identify patients with myelopathy (neuropsychiatric ACR). Disease activity was assessed by the SLE activity index (SLEDAI) on the date of the event and functional capacity was assessed by the Expanded Disability Status Scale (EDSS) at the last visit.

RESULTS

We identified 14 (1.2%) patients with myelopathy. All were women with a mean age of 30±11.5 years. Myelopathy occurred at the diagnosis of SLE in four (28%) patients; and nine (64%) patients had another type of neuropsychiatric manifestation associated. Neurological recurrence was observed in one (7%) patient. Disease activity was observed in 2 (14%) patients. Cerebrospinal fluid presented pleocytosis on 7 (53%) patients; antiphospholipid antibodies were positive in 5 (45%). Magnetic resonance imaging (MRI) showed T2 hyperintensity with a predominance of longitudinal involvement in 6 (86%) patients. Most were treated with intravenous corticosteroids and cyclophosphamide. No patient had full recovery and four (36%) had high EDSS scores. Three (21%) patients died from sepsis early in the course of their myelopathy, during or after immunosuppressive therapy.

CONCLUSIONS

Myelopathy occurred in 14 (1.2%) of the patients in our cohort and this may be the first manifestation of the disease occurring independently of systemic disease activity. Although rare, myelopathy shows great morbidity and mortality, can be recurrent and MRI is critical for diagnosis.

Longitudinally extensive transverse myelitis with anti-NMDA receptor antibodies during a systemic lupus erythematosus flare-up

Transverse myelitis (TM) with systemic lupus erythematosus (SLE) has been linked to the presence of autoantibodies (eg, antiaquaporin 4 (AQP4) and anticardiolipin (aCL)) and SLE-induced secondary vasculitis, but the aetiology remains incompletely understood. A 48-year-old Japanese man with a 6-year history of poorly controlled SLE had stopped glucocorticoid therapy 1 year before admission. 3 days before admission, he developed flaccid paraplegia. Spinal MRI showed a longitudinally hyperintense T2 grey matter lesion from the level of Th4 to the conus medullaris, which was considered longitudinally extensive TM (LETM). We administered steroid pulse therapy (methyl-prednisolone 1000 mg/day) for 3 days and prednisolone 50 mg/day. The patient's flaccid paralysis gradually improved. We concluded that the patient's TM was caused by SLE flare-up, even though we could not completely rule out antiphospholipid syndrome. SLE myelitis is relatively rare and many aetiologies are possible for TM in SLE.

Current treatment of antiphospholipid syndrome: lights and shadows

For patients with antiphospholipid syndrome (APS), the consensus is to treat those who develop thrombosis with long-term oral anticoagulation therapy and to prevent obstetric manifestations by use of aspirin and heparin. These recommendations are based on data from randomized controlled trials and observational studies. Despite this body of knowledge, areas of uncertainty regarding the management of APS exist where evidence is scarce or nonexistent. In other words, for a subset of patients the course of management is unclear. Some examples are patients with 'seronegative' APS, those who do not fulfil the formal (clinical or serological) classification criteria for definite APS, and those with recurrent thrombotic events despite optimal anticoagulation. Other challenges include the treatment of clinical manifestations not included in the classification criteria, such as haematologic manifestations (thrombocytopenia and haemolytic anaemia), neurologic manifestations (chorea, myelitis and multiple sclerosis-like lesions), and nephropathy and heart valve disease associated with antiphospholipid antibodies (aPL), as well as the possible withdrawal of anticoagulation treatment in selected cases of thrombotic APS in which assays for aPL become persistently negative. This Review focuses on the current recommendations for thrombotic and obstetric manifestations of APS, as well as the management of difficult cases. Some aspects of treatment, such as secondary prophylaxis of venous thrombosis, are based on strong evidence--the 'lights' of APS treatment. Conversely, other areas, such as the treatment of non-criteria manifestations of APS, are based only on expert consensus or common sense and remain the 'shadows' of APS therapy.

Advanced and Conventional Magnetic Resonance Imaging in Neuropsychiatric Lupus

Neuropsychiatric lupus is a major diagnostic challenge, and a main cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Magnetic resonance imaging (MRI) is, by far, the main tool for assessing the brain in this disease. Conventional and advanced MRI techniques are used to help establishing the diagnosis, to rule out alternative diagnoses, and recently, to monitor the evolution of the disease. This review explores the neuroimaging findings in SLE, including the recent advances in new MRI methods.

Lupus or syphilis? That is the question!

A 47-year-old man presented with fever, a maculopapular rash of the palms and soles, muscular weakness, weight loss, faecal incontinence, urinary retention and mental confusion with 1 month of evolution. Neurological examination revealed paraparesis and tactile hypoesthesia with distal predominance, and no sensory level. Laboratory investigations revealed a venereal disease research laboratory (VDRL) titre of 1/4 and Treponema pallidum haemagluttin antigen (TPHA) of 1/640, positive anti-nuclear antibodies of 1/640 and nephrotic proteinuria (3.6 g/24 h). Lumbar puncture excluded neurosyphilis, due to the absence of TPHA and VDRL. The diagnosis of systemic lupus erythematosus (SLE) was established and even though transverse myelitis as a rare presentation of SLE has a poor outcome, the patient improved with cyclophosphamide, high-dose corticosteroids and hydroxychloroquine. A diagnosis of secondary syphilis was also established and the patient was treated with intramuscular benzathine penicillin G.

Myelitis transverse in Sjögren's syndrome and systemic lupus erythematosus: presentation of 3 cases

Transverse myelitis is a rare focal inflammation of the spinal cord. Multiple etiologies have been identified including autoimmune diseases, mainly systemic lupus erythematosus and Sjögren' syndrome. It can occur in an acute or subacute clinical onset, with the acute presentation having a worse prognosis. An early diagnosis and intensive treatment are important features recommended in these patients. We present three cases with transverse myelitis associated with autoimmune diseases. We discuss different clinical manifestations, association with autoantobodies, radiologic findings, and therapeutic and prognostic issues.

Longitudinally extensive transverse myelitis

PURPOSE OF REVIEW

Longitudinally extensive transverse myelitis (LETM) is a frequently devastating clinical syndrome which has come into focus for its association with neuromyelitis optica (NMO). Recent advances in the diagnosis of NMO have led to very sensitive and specific tests and advances in therapy for this disorder. LETM is not pathognomonic of NMO, therefore it is important to investigate for other causes of myelopathy in these patients. This review aims to discuss recent advances in NMO diagnosis and treatment, and to discuss the differential diagnosis in patients presenting with LETM.

RECENT FINDINGS

Fluorescence-activated cell sorting and cell binding assays for NMO-IgG are the most sensitive for detecting NMO spectrum disorders. Patients who have a clinical presentation of NMO, who have been tested with older ELISA or immunofluorescence assay and been found to be negative, should be retested with a fluorescence-activated cell sorting assay when available, particularly in the presence of recurrent LETM. Novel therapeutic strategies for LETM in the context of NMO include eculizumab, which could be considered in patients with active disease who have failed azathioprine and rituximab. Thorough investigation of patients with LETM who are negative for NMO-IgG may lead to an alternate cause for myelopathy.

SUMMARY

LETM is a heterogeneous condition. Novel treatment strategies are available for NMO, but other causes need to be excluded in NMO-IgG-seronegative patients.

Adult-onset spastic paraparesis: an approach to diagnostic work-up

Adult-onset, chronic progressive spastic paraparesis may be due to a large number of causes and poses a diagnostic challenge. There are no recent evidence-based guidelines or comprehensive reviews to help guide diagnostic work-up. We survey the literature on chronic progressive spastic paraparesis, with special emphasis on myelopathies, and propose a practical, MRI-based approach to facilitate the diagnostic process. Building on neuro-anatomic and radiographic conventions, we classify spinal MRI findings into six patterns: extradural; intradural/extramedullary; Intramedullary; Intramedullary-Tract specific; Spinal Cord Atrophy; and Normal Appearing Spinal Cord. A comprehensive differential diagnosis of chronic progressive myelopathy for each of the six patterns is generated. We highlight some of the more common and/or treatable causes of progressive spastic paraparesis and provide clinical pointers that may assist clinicians in arriving at the diagnosis. We outline a practical, comprehensive MRI-based algorithm to diagnosing adult-onset chronic progressive myelopathy.

Systemic lupus erythematosus-associated acute transverse myelitis: manifestations, treatments, outcomes, and prognostic factors in 20 patients

Background

Transverse myelitis is a rare complication of systemic lupus erythematosus (SLE). This retrospective multicentre study identifies the prognostic factors in a relatively large patient series.

Patients and methods

Twenty patients fulfilled the SLE criteria of the ACR classification and the Transverse Myelitis Consortium Working Group. A severe neurological flare was defined as muscle strength grade <3/5 in more than half the muscle groups at the motor neurological level. Inability to run or another significant ambulation-unrelated disability was considered as ‘unfavourable neurological outcome’.

Results

Myelitis was the first SLE symptom in 12 patients; in the eight others, it occurred 8.6 years (median delay) after SLE onset. Eleven patients presented severe neurological impairments. The treatment included corticosteroids in all patients associated with intravenous cyclophosphamide in 11 and/or hydroxychloroquine in 14. Unfavourable outcomes were observed in 53% of the patients at six months and in 28% at end of follow-up (median: 5.9 years). An initial severe neurological impairment and no cyclophosphamide use were associated with unfavourable neurological outcomes at six months and at end of follow-up, respectively.

Conclusion

Transverse myelitis may reveal SLE or occur more than 10 years after SLE diagnosis. The initial severity of the neurological flare (with paraplegia) is the main prognostic marker. The study provides arguments for cyclophosphamide use.

Myelitis in systemic lupus erythematosus frequently manifests as longitudinal and sometimes occurs at low disease activity

Background

Transverse myelitis (TM) is a relatively infrequent but severe complication in systemic lupus erythematosus (SLE). Owing to its rarity and unfavorable outcome, we investigated its general features on MRI and incidence in the context of lupus activity, to facilitate early recognition and treatment.

Methods

We report a case of a young man with clinically inactive lupus nephritis but who presented with a sudden attack of myelitis. We performed systematic literature search in Medline to study the clinical features of SLE-related TM.

Results

From 1960 to April 2013, a total of 72 articles containing 194 cases of lupus myelitis were found. Among acquired articles, 93 patients fulfilled the inclusion criteria. The majority of the cases (88.8%) were female. Longitudinal myelitis was the predominant imaging finding on MRI (71.4%, 45/63). Nearly two-thirds (61/94) of lupus myelitis occurred in association with active lupus, and one-third (33/94) occurred in low disease activity.

Conclusions

Upon literature review, we found myelitis in SLE more frequently manifested as longitudinal on MRI. Although lupus myelitis often presented at an active phase of SLE, one-third of events happened in the presence of low disease activity. Early initiation of effective immunosuppressive therapy facilitated recovery.

Demyelinating disease in SLE: is it multiple sclerosis or lupus?

Among the 12 systemic lupus erythematosus (SLE)-related central nervous system (CNS) syndromes defined by the American College of Rheumatology (ACR), demyelinating syndrome and myelopathy are two of the less prevalent and more poorly understood ones. One important issue concerning demyelinating disease in SLE is that it can be easily misdiagnosed with other central nervous system demyelinating disorders such as multiple sclerosis (MS). A clinically isolated neurological syndrome can be the presenting feature before other concomitant symptoms of SLE appear or definite MS is diagnosed. Although challenging, some diagnostic tests used in clinical practice and research may help to differentiate between these entities. These tests have improved the understanding of the pathogenesis in these diseases, but some points, such as the role of antiphospholipid antibodies in SLE-associated transverse myelitis, remain unclear and are a matter of ongoing debate. This review discusses clinical, pathophysiological, radiological and therapeutic concepts of demyelinating disease of the CNS in SLE, focussing on its differentiation from MS and its relation with other CNS demyelinating processes, such as transverse myelitis, optic neuritis and neuromyelitis optica.

Acute longitudinal myelitis as the first presentation in child with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a multi-system auto-immune disorder that is characterized by widespread immune dysregulation, formation of auto–antibodies, and immune complexes, resulting in inflammation and potential damage to variety of organs. It is complicated by neurological manifestations in 25-95% of the patients. Acute transverse myelitis (ATM) may be a complication in 1-2% of patients with SLE but in some patients it may be the initial manifestation of SLE. This sub-group of patients where ATM is the presenting feature may not fulfil the ACR criteria for the diagnosis of SLE which may delay the diagnosis and may affect the outcome. In those patients where the involvement is more than four segments of the spine are believed to have poor prognosis, but early diagnosis and treatment may alter the course and lead to a better outcome. We describe a young Polish girl where ATM was the initial manifestation of SLE involving almost the whole length of spine but she had a reasonably good outcome following early diagnosis and aggressive treatment.

Longitudinally extensive transverse myelitis associated with dengue fever

Longitudinally extensive transverse myelitis (LETM) is usually associated with neuromyelitis optica and other autoimmune and inflammatory disorders but this is the first report linking it with dengue fever. Dengue infection can cause a variety of neurological complications which may result in poor recovery and long-term disability. The authors report here a patient who developed LETM in the para-infectious stage of dengue fever. The patient had a complicated clinical course resulting in severe paraparesis and urinary retention. Treatment with immunoglobulins and antiviral agents supported by a spell of early intensive rehabilitation programme produced excellent results in terms of recovery.
