Abstract: PURPOSE: To describe clinical and physiopathological aspects of neurological involvement in neurological Sjögren syndrome (SS) and to overview biological markers and therapeutical aspects. CURRENT KNOWLEDGE AND KEY POINTS: Neurological complications during SS may occur between 8.5 and 70%. Peripheral nervous system (PNS) involvement is well none but data concerning central nervous system (CNS) symptoms have been rarely described. In the present study we detail more precisely the heterogeneity of the neurological manifestation in SS. Recently new biological of SS such as alpha-fodrin antibodies have been described but there interest remain controversial. Furthermore, therapeutical data are scarce and there is to date no consensual guidelines for the therapeutical approach. PERSPECTIVE: Recent data concerning neurological involvement in SS confirm the heterogeneity of clinical presentations that may mimic stroke or multiple sclerosis. They underline the need for new biological markers. Furthermore, multicentric, randomized trials should be assessed in order to give us some therapeutical guidelines.

Abstract: BACKGROUND: Neuromyelitis optica (NMO) is often associated with other clinical or serological markers of non-organ-specific autoimmunity. OBJECTIVE: To evaluate the relationship between NMO spectrum disorders (NMOSDs), including NMO, longitudinally extensive transverse myelitis, and recurrent optic neuritis, and autoimmune disease. We concentrated on the association with systemic lupus erythematosus (SLE), Sjögren syndrome (SS), or serological evidence of these disorders, which commonly is a source of diagnostic confusion. DESIGN: Retrospective blinded serological survey. SETTING: Mayo Clinic College of Medicine, Rochester, and Centre Hospitalier Régional Universitaire de Lille. METHODS: Group 1 included 153 US patients with NMOSDs (78 with NMO and 75 with longitudinally extensive transverse myelitis) and 33 control subjects with SS/SLE. Group 2 included 30 French patients with SS/SLE, 14 with NMOSDs (6 with NMO, 6 with longitudinally extensive transverse myelitis, and 2 with recurrent optic neuritis), 16 without NMOSDs, and 4 with NMO without SS/SLE. RESULTS: For group 1, NMO-IgG was detected in 66.7%, antinuclear antibodies in 43.8%, and Sjögren syndrome A (SSA) antibodies in 15.7% of patients with NMO and longitudinally extensive transverse myelitis. Five NMO-IgG-seropositive patients with NMOSDs had coexisting SLE, SS, or both. Antinuclear antibodies and SSA antibodies were more frequent in NMO-IgG-seropositive patients than in NMO-IgG-seronegative patients (P= .001). For group 2, NMO-IgG was detected in 5 of 14 patients (35.7%) with NMOSDs and SS/SLE and in 2 of 4 patients (50.0%) with NMO without SS/SLE (P= .59). We detected NMO-IgG only in patients with NMOSDs and not in 49 controls with SS/SLE but without optic neuritis or myelitis from the 2 cohorts (P= .01). CONCLUSION: Neuromyelitis optica spectrum disorders with seropositive findings for NMO-IgG occurring with SS/SLE or non-organ-specific autoantibodies is an indication of coexisting NMO rather than a vasculopathic or other complication of SS/SLE.

Abstract: BACKGROUND: Polymyositis with cranial neuropathy has been rarely reported. CASE REPORTS: We describe here three cases of polymyositis with trigeminal or facial neuropathy. Patients had muscular weakness, myalgia, rhabdomyolysis, endomysial infiltration with necrosis and regeneration at biopsy of muscle and, for two of them, a myopathic pattern at electromyogram. Two patients had also a Sjögren's syndrome and anti-nuclear antibodies. Anti-JO1 antibodies were presents in only one case. The outcome for one patient was good with corticosteroids alone. One other improved with the adjunction of immunoglobulin. The third one had a macrocheilia, a facial diplegia, antibodies against voltage-gated potassium channels and a neuromyotonia secondary to a paraneoplastic syndrome. He died after one year despite a treatment by corticosteroids and immunoglobulin. Patients fulfilled the diagnosis of polymyositis according to clinical, electromyographic, biological and histopathologic criteria. For the two patients with Sjögren's syndrome, the question of a primitive or a secondary Sjögren's syndrome remains unknown. CONCLUSION: The occurrence of a cranial neuropathy in polymyositis should make us looking for an association with paraneoplastic syndrome or connective tissue disease.

Abstract: OBJECTIVE: To characterize discriminant human brain antigenic targets in patients with neuropsychiatric systemic lupus erythematosus (NPSLE), using a standardized immunoproteomic approach. METHODS: Self-IgG reactivity against normal and injured human brain tissues was studied by Western blotting of sera from 169 subjects, 16 patients with NPSLE, 12 patients with SLE without neuropsychiatric manifestations (non-NPSLE), 32 patients with Sjögren's syndrome with or without central nervous involvement, 82 patients with multiple sclerosis, and 27 healthy subjects. A proteomic approach was then applied to characterize discriminant antigens identified after comparisons of all patterns. RESULTS: The serum self-IgG reactivity patterns against human brain tissue differed significantly between patients with NPSLE and the control groups. Four normal brain antigenic bands were specifically or preferentially recognized by sera from NPSLE patients (p240, p90, p77, and p24). Protein band p240 was characterized as microtubule-associated protein 2B (MAP-2B), p77 as Hsp70-71, and p24 as triosephosphate isomerase. Protein band p90 was not characterized. In contrast, 1 other protein band (p56, characterized as septin 7) was never recognized by sera from NPSLE patients but was recognized by a majority of sera from non-NPSLE patients. CONCLUSION: Our findings show that the immunoproteomic approach is a reliable method for assessing serum self-IgG reactivities against human brain tissue in NPSLE. Our characterization of some of the identified discriminant antigens, such as MAP-2B, triosephosphate isomerase, and septin 7, suggests that the stability of neuronal microtubules might be involved in the pathophysiology of NPSLE.

Abstract: OBJECTIVE: Central nervous system manifestations in Sjögren's syndrome (SS) include focal deficits, optic neuritis, and myelopathies. Acute and chronic myelopathies are frequently severe and sometimes respond poorly to corticosteroids. The efficacy of intravenous (IV) cyclophosphamide (CYC) has been suggested in single case reports. METHODS: We describe the potential usefulness of IV CYC in SS patients with severe myelopathies. Fourteen patients [with acute (n = 6) and chronic (n = 8) myelopathies] were treated with monthly CYC infusions (700 mg/m2) in addition to 500 mg of corticosteroids for one year. We evaluated the disability before and after CYC treatment using a walking distance calculation and the Expanded Disability Status Scale (EDSS). RESULTS: CYC treatment was well tolerated in all cases without serious adverse events. Nine patients (including the 6 with acute myelopathy) were improved after CYC treatment. Three patients were stabilized and 2 patients with chronic myelopathies had moderate progression of disability. The mean walking distance increased from 48.2 m before to 180.4 m after CYC treatment (p < 0.02). Mean EDSS score decreased from 6.6 to 5.7 (not significant). We found a correlation between the length of time before CYC treatment and clinical improvement for both the walking distance (p < 0.02) and the EDSS score (p < 0.05). CONCLUSION: Although a randomized multicenter controlled study is warranted to confirm our findings, IV CYC infusions seem to be useful for the treatment of myelopathies secondary to SS, particularly in acute but also in progressive cases. This treatment should be strongly considered as soon as possible when disease progression is observed.

Abstract: INTRODUCTION: Adie's syndrome is usually a disease of unknown origin. We report two cases secondary to Sjögren syndrome. CASE REPORTS: A 26-year-old man developed in few months a sensitive neuropathy with a bilateral tonic pupil. A 50-year-old woman complained of sensitive signs probably related to a ganglionopathy and dysautonomic disorders affecting sudomotor and vasomotor functions. Adie syndrome had been diagnosed three years earlier. In both patients, the systemic signs and the results of the complementary tests led to the diagnosis of Sjögren's syndrome. Corticosteroids had limited effects on the sensitive signs and no influence on the tonic pupils. CONCLUSION: Adie syndrome, isolated or accompanied by other dysautonomic disorders, may reveal or precede the diagnosis of Sjögren's syndrome.

Abstract: Neurologic involvement occurs in approximately 20% of patients with primary Sjögren syndrome (SS). However, the diagnosis of SS with neurologic involvement is sometimes difficult, and central nervous system (CNS) manifestations have been described rarely. We conducted the current study to describe the clinical and laboratory features of SS patients with neurologic manifestations and to report their clinical outcome. We retrospectively studied 82 patients (65 women and 17 men) with neurologic manifestations associated with primary SS, as defined by the 2002 American-European criteria. The mean age at neurologic onset was 53 years. Neurologic involvement frequently preceded the diagnosis of SS (81% of patients). Fifty-six patients had CNS disorders, which were mostly focal or multifocal. Twenty-nine patients had spinal cord involvement (acute myelopathy [n = 12], chronic myelopathy [n = 16], or motor neuron disease [n = 1]). Thirty-three patients had brain involvement and 13 patients had optic neuropathy. The disease mimicked relapsing-remitting multiple sclerosis (MS) in 10 patients and primary progressive MS in 13 patients. We also recorded diffuse CNS symptoms: some of the patients presented seizures (n = 7), cognitive dysfunction (n = 9), and encephalopathy (n = 2). Fifty-one patients had peripheral nervous system involvement (PNS). Symmetric axonal sensorimotor polyneuropathy with a predominance of sensory symptoms or pure sensory neuropathy occurred most frequently (n = 28), followed by cranial nerve involvement affecting trigeminal, facial, or cochlear nerves (n = 16). Multiple mononeuropathy (n = 7), myositis (n = 2), and polyradiculoneuropathy (n = 1) were also observed. Thirty percent of patients (all with CNS involvement) had oligoclonal bands. Visual evoked potentials were abnormal in 61% of the patients tested. Fifty-eight patients had magnetic resonance imaging (MRI) of the brain. Of these, 70% presented white matter lesions and 40% met the radiologic criteria for MS. Thirty-nine patients had a spinal cord MRI. Abnormalities were observed only in patients with spinal cord involvement. Among the 29 patients with myelopathy, 75% had T2-weighted hyperintensities. Patients with PNS manifestations had frequent extraglandular complications of SS. Anti-Ro/SSA or anti-La/SSB antibodies were detected in 21% of patients at the diagnosis of SS and in 43% of patients during the follow-up (mean follow-up, 10 yr). Biologic abnormalities were more frequently observed in patients with PNS involvement than in those with CNS involvement (p < 0.01). Fifty-two percent of patients had severe disability, and were more likely to have CNS involvement than PNS involvement (p < 0.001). Treatment by cyclophosphamide allowed a partial recovery or stabilization in patients with myelopathy (92%) or multiple mononeuropathy (100%). The current study underlines the diversity of neurologic complications of SS. The frequency of neurologic manifestations revealing SS and of negative biologic features, especially in the event of CNS involvement, could explain why SS is frequently misdiagnosed. Screening for SS should be systematically performed in cases of acute or chronic myelopathy, axonal sensorimotor neuropathy, or cranial nerve involvement. The outcome is frequently severe, especially in patients with CNS involvement. Our study also underlines the efficacy of cyclophosphamide in myelopathy and multiple neuropathy occurring during SS.

Abstract: The present study was performed in order to confirm the diagnostic value of isoelectrofocusing (IEF) in a large multiple sclerosis (MS) cohort and to evaluate the various neurological diseases probably to present a similar IEF profile. The cerebrospinal fluid (CSF) of 1292 patients with neurological diseases was studied by IEF. After a follow-up of 2-36 months, we only included patients with a definite MS or confirmed diagnosis of other neurological diseases (OND). MS was diagnosed in 407 patients and OND in 593 patients. For patients in whom three or more oligoclonal bands (OCB) were detected, IEF results showed a sensitivity of 85% and a specificity of 92% for the diagnosis of MS. The positive and negative predictive values were 86.5 and 90%, respectively. Inflammatory and infectious disorders of the central nervous system represented the main affections associated with OCB, including human immunodeficiency virus encephalitis, Lyme disease and less frequently Sjogren syndrome. Furthermore, when OCB were observed, 10 or more bands were more frequently found in MS than in OND (P < 0.0001). IEF of the CSF is a reliable method for the diagnosis of MS. The absolute number of bands may help to discriminate between MS and OND.

Abstract: OBJECTIVE: To investigate the diagnostic value of autoantibodies against alpha-fodrin in patients with Sjögren's syndrome (SS) with neurological manifestations compared to SS patients without neurological manifestations, a control group, and patients with other neurological autoimmune diseases including systemic lupus erythematosus (SLE) with neurological manifestations and multiple sclerosis (MS). METHODS: We evaluated alpha-fodrin autoantibodies in 31 patients with SS with neurological manifestations, 53 SS patients without neurological symptoms, 38 patients with SLE, 60 with MS, and 160 controls. RESULTS: Twenty of the 31 SS patients with neurological manifestations (64.5%) had an increased concentration of IgA and/or IgG anti-alpha-fodrin. This was not statistically different from that of SS patients without neurological symptoms (73.6%), but was higher than the number with SSA/SSB antibodies, which were found in 15 (48%) of our SS patients without neurological manifestations. When the results of the 2 tests were combined, 28 of the 31 (90.3%) patients had positive autoantibodies (alpha-fodrin and/or SSA/SSB). Alpha-fodrin antibodies were increased in 8 (13.3%) of the 60 patients with MS, in 6 (15.7%) of 38 patients with SLE, and in 10 (6.3%) of 160 controls. CONCLUSION: Our results confirm that alpha-fodrin antibodies are an additional diagnostic tool for SS. This test is of particular interest for patients with SS with neurological manifestations, in whom anti SSA/SSB antibodies are less frequently found.

Abstract: To date, none of the myelin-associated Ag targets definitively discriminates between the immune response observed in multiple sclerosis (MS) patients and healthy subjects. However, it has been shown recently that analysis of global immune Ab profiles such as natural autoantibody reactivities can help to distinguish between normal individuals and patients suffering from various immune diseases. The aim of our study was to compare the global IgG immune response against brain self-Ags in sera from 82 MS patients and 27 healthy subjects. The analysis of the immune profiles was performed by Western blotting, and data were subjected to linear discriminant analysis. Particular patterns of IgG reactivity were found in healthy subjects, Sjögren patients, and MS patients. Moreover, this approach separated the three clinical forms of MS with a high concordance rate with the clinical data (kappa value, 77.8%). Our study suggests, for the first time, that serum IgG Ab repertoires are able to distinguish MS patients. In addition, our data suggest that patterns of IgG reactivity could model the pathological processes underlying the various forms of MS. Further characterization of such discriminant Ags could provide useful information regarding their potent role in pathogenesis or regulatory processes in MS.

Abstract: OBJECTIVE: To assess the prevalence of Sjögren syndrome (SS) in patients with primary progressive MS (PPMS). BACKGROUND: SS may be considered in the differential diagnosis of MS. Age at onset and clinical presentation are similar in SS and PPMS. However, occurrence of SS in definite cases of PPMS has been recently reported. METHODS: Proposed clinical and laboratory diagnostic criteria for SS were systematically assessed in 60 consecutive patients with PPMS. The authors questioned all patients about xerophthalmia and xerostomia, biopsied minor salivary glands, and performed a Schirmer test, a salivary gland scintigraphy, and anti-Ro (SSa) and anti-La (SSb) serologies. RESULTS: Ten patients (16.6%) met four or more criteria for SS. This prevalence is higher than in the general population (1 to 5%) and implies that SS can mimic PPMS. CONCLUSIONS: The authors propose that SS should be screened for systematically in patients with PPMS.

Abstract: Myelopathies associated with Sjögren's syndrome has been rarely described especially concerning magnetic resonance imaging (MRI) and treatment aspects. The aim of this study was to determine the clinical, laboratory and radiological features of myelopathies occurring in Sjögren's syndrome. Eleven patients were studied, 7 with an acute myelopathy and 4 with a chronic form. Acute myelopathy were clinically severe with a feature of transverse myelitis necessitating immunosuppressive drugs. On the other hand, chronic forms were closely similar to progressive multiple sclerosis (MS), for clinical and laboratory data. In 7 cases optic neuritis was found associated with myelopathy and fulfilled the diagnostic criteria of Devic's syndrome in 4 cases. The diagnosis of myelopathy associated with Sjögren's syndrome may be difficult especially compared with MS, HTLV1 or HIV myelopathy and sarcoidosis, in the chronic form but also with other vasculitis, MS or viral infection in the acute forms. However, in this last form, magnetic resonance imaging and cerebrospinal fluid data should bring to the diagnosis of Sjögren syndrome and confirmed by appropriate tests. This diagnosis will have direct consequences for an early treatment by immunosuppressive drugs.
