Abstract
Spinocerebellar ataxia type 2 (SCA2) is a dominantly inherited ataxia primarily characterised by progressive cerebellar syndrome, which is developed due to the expansion of the CAG trinucleotide repeat within the first exon of the ATXN2 gene. We report a rare case of a 41-year-old woman with coexistent genetically verified SCA2 and primary progressive multiple sclerosis (MS). Considering our case and a few others reported in the literature, as well as a possible genetic association between ATXN2 and MS susceptibility, we suggest that the coexistence of SCA and MS may not be coincidental, especially in patients with a progressive MS course.

Validation of the Behçet's Syndrome Overall Damage Index (BODI) for Retrospective Studies and a Proposal for Modification. Rheumatology (Oxford) 2024:keae266. [PMID: 38733594 DOI: 10.1093/rheumatology/keae266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 04/21/2024] [Accepted: 04/29/2024] [Indexed: 05/13/2024] Open
Abstract
OBJECTIVE Assessment of damage accrual over time is important for evaluating and comparing long-term results of treatment modalities and strategies. Retrospective studies may be useful for assessing long-term damage, especially in rare diseases. We aimed to validate Behçet's Syndrome Overall Damage Index (BODI) for use in retrospective studies by evaluating its construct validity, reliability, and feasibility in retrospectively collected data. Additionally, we aimed to determine missing items by evaluating Behçet's syndrome patients with different types of organ involvement and long-term follow-up. METHODS We included 300 patients who had at least 2 clinic visits at 1-year intervals. The construct validity for use in retrospective trials was assessed by comparing BODI scores calculated from patient charts and during face-to-face visits. BODI was additionally scored using retrospective chart data by 2 different observers and by the same observer six months apart, in a blinded manner. The time for filling BODI was evaluated to assess feasibility. Additionally, damaged items that were missing from BODI were identified. RESULTS There was a good correlation between the retrospective and face-to-face evaluation of BODI (ICC 0.99; %95 CI 0.99-0.99). Inter-observer and intra-observer agreement were good (ICC 0.96 and 1, respectively). The main damage items that BODI did not capture were hypertension, liver failure, lung parenchymal involvement, glaucoma, and lymphedema. CONCLUSION BODI seems to be a reliable and feasible instrument for assessing damage in retrospective studies. Modifying BODI using the additional damage items identified in this study may make it an even better scale.

The diagnostic workup of children with the radiologically isolated syndrome differs by age and by sex. J Neurol 2024:10.1007/s00415-024-12289-1. [PMID: 38564056 DOI: 10.1007/s00415-024-12289-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 02/19/2024] [Accepted: 02/29/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND Cerebrospinal fluid (CSF) and spinal MRIs are often obtained in children with the radiologically isolated syndrome (RIS) for diagnosis and prognosis. Factors affecting the frequency and timing of these tests are unknown. OBJECTIVE To determine whether age or sex were associated with (1) having CSF or spinal MRI obtained or (2) the timing of these tests. METHODS We analyzed children (≤ 18 y) with RIS enrolled in an international longitudinal study. Index scans met 2010/2017 multiple sclerosis (MS) MRI criteria for dissemination in space (DIS). We used Fisher's exact test and multivariable logistic regression (covariates = age, sex, MRI date, MRI indication, 2005 MRI DIS criteria met, and race). RESULTS We included 103 children with RIS (67% girls, median age = 14.9 y). Children ≥ 12 y were more likely than children < 12 y to have CSF obtained (58% vs. 21%, adjusted odds ratio [AOR] = 4.9, p = 0.03). Pre-2017, girls were more likely than boys to have CSF obtained (n = 70, 79% vs. 52%, AOR = 4.6, p = 0.01), but not more recently (n = 30, 75% vs. 80%, AOR = 0.2, p = 0.1; p = 0.004 for interaction). Spinal MRIs were obtained sooner in children ≥ 12 y (median 11d vs. 159d, p = 0.03). CONCLUSIONS Younger children with RIS may be at continued risk for misdiagnosis and misclassification of MS risk. Consensus guidelines are needed.

Erdheim-Chester disease of brain parenchyma without any systemic involvement: A case report and review of literature. Neuropathology 2024; 44:59-67. [PMID: 37357975 DOI: 10.1111/neup.12930] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/08/2023] [Accepted: 06/11/2023] [Indexed: 06/27/2023]
Abstract
Erdheim-Chester disease is a non-Langerhans cell histiocytosis syndrome characterised by histiocytic infiltration of different organs and systems in the body. Erdheim-Chester disease with isolated central nervous system (CNS) involvement causes diagnostic difficulties due to the absence of systemic findings and may result in misdiagnosis and inaccurate treatment choices. The case discussed in this report exemplifies how challenging it is to diagnose Erdheim-Chester disease with isolated CNS involvement. This case, which presented with progressive pyramidocerebellar syndrome, was clinically and radiologically resistant to all immunosuppressive and immunomodulatory treatments administered. The presence of false negative results in repeated histopathological investigations and the absence of evidence for systemic disease hindered the diagnosis and treatment work-up. In this study, we reviewed and discussed the prominent features of the presented case in light of the relevant literature.

Retinal and peripapillary vascular density in episodic and chronic migraine cases without aura. Photodiagnosis Photodyn Ther 2023; 44:103809. [PMID: 37739046 DOI: 10.1016/j.pdpdt.2023.103809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/17/2023] [Accepted: 09/19/2023] [Indexed: 09/24/2023]
Abstract
BACKGROUND Migraine is a neurovascular disease that can cause ocular and systemic ischemic damage. Despite from aura, a limited number of studies have considered the effect of the chronic migraine in cases without aura. Our aim was to evaluate the differences in the retinal and optic disk microvasculature among episodic and chronic migraine cases without aura using optical coherence tomography angiography (OCTA) imaging. METHODS 45 cases with migraine, and 25 control subjects were included in this prospective, cross-sectional study. OCTA was performed at 3 × 3 mm and 6 × 6 mm of the macula and at 4.5 × 4.5 mm of the optic disk. Retinal nerve fiber layer (RNFL) thickness, ganglion cell complex thickness, and vessel densities of the optic nerve and macula were compared among the three groups: a control group, an episodic migraine without aura (EMWOA) group, and a chronic migraine without aura (CMWOA) group. RESULTS In EMWOA group, circumpapillary vascular density (cpVD) was not decreased significantly in any quadrants (all, p>0.05). Compared to the control group, CMWOA group had significantly lower RNFL thickness in superior-temporal quadrants (p = 0.002 and 0.006, respectively), while cpVD differed only in the temporal quadrant and temporal inferior sector (p = 0.002 and p = 0.009, respectively). CONCLUSIONS Temporal peripapillary perfusion is valuable in the follow-up of chronic migraine cases. Longitudinal studies are needed to determine the place of OCTA in the follow-up of migraine.

Severe disease reactivation in seropositive neuromyelitis optica spectrum disorders patients after stopping eculizumab treatment. Mult Scler Relat Disord 2023; 79:104949. [PMID: 37678131 DOI: 10.1016/j.msard.2023.104949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 05/31/2023] [Accepted: 08/20/2023] [Indexed: 09/09/2023]
Abstract
INTRODUCTION Neuromyelitis optica spectrum disorders (NMOSD) is an autoimmune, inflammatory disease of the central nervous system affecting the optic nerves and spinal cord. Most NMOSD patients have autoantibodies against the astrocyte water channel protein aquaporin-4 (AQP4). Eculizumab treatment is used effectively and safely in AQP4-IgG+ NMOSD. Our study evaluated the prognosis and outcomes of all clinical trial (PREVENT) patients from Turkey who received eculizumab treatment for AQP4-IgG+ NMOSD. METHOD Clinical and demographic data of all patients enrolled in the PREVENT and OLE clinical trial in Turkey were analyzed during the study period and after the study ended. Clinical follow-up results were recorded in detail in patients who had to discontinue eculizumab treatment. RESULTS The study included 10 patients who participated in PREVENT and OLE. Seven patients completed the studies, three patients did not continue the study and were switched to other treatments. Only one of the seven patients was able to continue treatment after eculizumab was approved in AQP4-IgG+NMOSD. The other six patients could not continue treatment due to reimbursement conditions. Four of the six patients who could not continue eculizumab treatment experienced early relapse (within the first three months after stopping the drug). All of these patients had high disease activity before eculizumab and had never relapsed under eculizumab treatment over the long term. CONCLUSION Eculizumab was used effectively and safely in Turkish AQP4-IgG+NMOSD patients with high disease activity. Disease reactivation and relapse may occur after discontinuation of eculizumab treatment in patients with a long-term stable course. In these cases, close monitoring for disease reactivation is recommended.

Abstract
BACKGROUND Patients with multiple sclerosis (MS) who discontinue fingolimod might present with rebound activity. The reasons for the development of rebound have been identified, but there are limited data on the long-term clinical outcomes of these patients. This study aimed to compare the long-term outcomes of patients with MS with and without rebound activity after fingolimod discontinuation. METHODS A total of 31 patients who discontinued fingolimod for various reasons with a minimum follow-up of 5 years were included in the study. Of these, 10 were assigned to the rebound group and 21 to the non-rebound group. Clinical and demographic data and 5-year clinical outcomes of both groups were prospectively examined. RESULTS At fingolimod initiation, there were no significant differences in age, disease duration, and Expanded Disability Status Scale (EDSS) score. The annualized relapse rate (ARR) was significantly higher in the rebound group than in the non-rebound group before the fingolimod treatment (p = 0.005). In the rebound group, EDSS scores 2 months after rebound treatment and at the 5-year follow-up were not significantly different than before fingolimod initiation (p = 0.14 and p = 0.46, respectively). The last recorded EDSS was significantly higher in the non-rebound group than in the rebound group (3.6 ± 2.3 vs. 2.15 ± 1.4, p = 0.045). At the last follow-up, one patient was diagnosed with secondary progressive multiple sclerosis in the rebound group (10%), and 11 patients were in the non-rebound group (52.4%, p = 0.05). CONCLUSION When rebound activity is well-monitored and treated after fingolimod discontinuation, no overall EDSS change is expected in the long-term follow-up.

Abstract
OBJECTIVE Vascular involvement is an important cause of morbidity and mortality in patients with Behçet's syndrome (BS). We aimed to survey the efficacy and safety of infliximab (IFX) in BS patients with vascular involvement followed in a dedicated tertiary center. METHODS Charts of all BS patients who used IFX for vascular involvement between 2004 and 2022 were reviewed. Primary endpoint was remission at Month 6, defined as lack of new clinical symptoms and findings associated with vascular lesion, lack of worsening of the primary vascular lesion and a new vascular lesion on imaging, and CRP < 10 mg/L. Relapse was defined as development of a new vascular lesion or recurrence of the preexisting vascular lesion. RESULTS Among the 127 patients (102 men, mean age at IFX initiation: 35.8 ± 9.0 years) treated with IFX, 110 (87%) had received IFX for remission induction and 87 of these (79%) were already on immunosuppressives when the vascular lesion requiring IFX developed. The remission rate was 73% (93/127) at Month 6 and 63% (80/127) at Month 12. Seventeen patients experienced relapses. Remission rates were better among patients with pulmonary artery involvement and venous thrombosis compared to patients with non-pulmonary artery involvement and venous ulcers. Fourteen patients had adverse events leading to IFX discontinuation and 4 had died due to lung adenocarcinoma, sepsis, and pulmonary hypertension-related right heart failure due to pulmonary artery thrombosis (n = 2). CONCLUSION Infliximab seems to be effective in majority of BS patients with vascular involvement, even in those who are refractory to immunosuppressives and glucocorticoids.

Abstract
BACKGROUND Predicting the long-term disability outcomes of multiple sclerosis (MS) cases is challenging. OBJECTIVE We prospectively analysed our previous MS cohort with initial cerebrospinal fluid (CSF) proteomics data to reveal disability markers after 8.2±2.2 years of follow-up. METHODS Patients with regular follow-up visits were assigned into two groups: those with an age-related MS severity (ARMSS) score ≥5 (unfavourable course group, N = 27) and ARMSS score <5 (favourable course group, N = 67). A machine learning-based algorithm was applied to reveal candidate poor prognosis-associated initial CSF proteins, which were measured in an independent MS cohort (verification group, N = 40) by ELISA. Additionally, the correlation of initial clinical and radiological parameters with long-term disability was analysed. RESULTS CSF alpha-2-macroglobulin (P = 0.0015), apo-A1 (P = 0.0016), and haptoglobin (P = 0.0003) protein levels, as well as cerebral lesion load (>9 lesions) on magnetic resonance imaging, gait disturbance (P = 0.04), and bladder/bowel symptoms (P = 0.01) were significantly higher in the unfavourable course group than in the favourable course group. Optic nerve involvement evident on initial magnetic resonance imaging (P = 0.002) and optic neuritis (P = 0.01) were more frequent in the favourable course group. CONCLUSION The herein identified initial CSF protein levels, in addition to the clinical and radiological parameters at disease onset, have predictive value for long-term disability in MS cases.

Abstract
ObjectiveTo determine the clinical, demographic and imaging characteristics of a Turkish cohort with aquaporin-4-antibody positive (AQP4-IgG+) neuromyelitis optica spectrum disorder (NMOSD) from a single center.BackgroundNA.Design/Methods35 patients seen between January-2008 and December-2020 with a diagnosis of AQP4-IgG+NMOSD who could be studied in detail were included in the study. Inclusion criteria for patients with NMOSD diagnosis was defined according to International Consensus Diagnostic Criteria (Wingerchuk et al.2015) and all patients were confirmed for AQP4-IgG positive serology at least once by Euroimmune transfected cells assay (EU90). Demographic, clinical and MRI data were obtained retrospectively.ResultsThe female-to-male ratio was 16.5: 1. The mean age of disease onset was 26,16±10,96 years for patients with optic neuritis onset (n:12), and 43.17±11,95 for the subgroup that started with transverse myelitis (TM) (n:16), confirming a significant difference of age at onset according to the first attack type (p < 0.001). The mean age at onset in 5 patients with area postrema syndrome was 35,74±16,83. Half of the total attacks occurred within the first year of disease onset (98/196). The mean time to diagnosis was 2,98±5,78 years after the initial attack. Disease duration was 10,06±9,76 years. Cerebrospinal fluid oligoclonal bands were studied in 24 and were positive in 25%. An autoimmune rheumatologic disease comorbidity was present in 34.5% of the patients. In patients with MRI disclosing = 2 McDonald dissemination in space criteria (spinal included) was more common in TM group and correlated with a higher disability (EDSS) score.ConclusionsTurkish AQP4-IgG+NMOSD patients whose disease start with optic neuritis have an earlier age of onset compared to the ones with TM onset. Half of the total attacks occur within the first year of disease onset. Patients with = 2 McDonald MRI dissemination in space criteria were more common in the TM group and had a higher disability (EDSS) score.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the predictive value of serum neurofilament light chain (sNfL) and CSF NfL (cNfL) in patients with radiologically isolated syndrome (RIS) for evidence of disease activity (EDA) and clinical conversion (CC). METHODS sNfL and cNfL were measured at RIS diagnosis by single-molecule array (Simoa). The risk of EDA and CC according to sNfL and cNfL was evaluated using the Kaplan-Meier analysis and multivariate Cox regression models including age, spinal cord (SC) or infratentorial lesions, oligoclonal bands, CSF chitinase 3-like protein 1, and CSF white blood cells. RESULTS Sixty-one patients with RIS were included. At diagnosis, sNfL and cNfL were correlated (Spearman r = 0.78, p < 0.001). During follow-up, 47 patients with RIS showed EDA and 36 patients showed CC (median time 12.6 months, 1-86). When compared with low levels, medium and high cNfL (>260 pg/mL) and sNfL (>5.0 pg/mL) levels were predictive of EDA (log rank, p < 0.01 and p = 0.02, respectively). Medium-high cNfL levels were predictive of CC (log rank, p < 0.01). In Cox regression models, cNfL and sNfL were independent factors of EDA, while SC lesions, cNfL, and sNfL were independent factors of CC. DISCUSSION cNfL >260 pg/mL and sNfL >5.0 pg/mL at diagnosis are independent predictive factors of EDA and CC in RIS. Although cNfL predicts disease activity better, sNfL is more accessible than cNfL and can be considered when a lumbar puncture is not performed. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that in people with radiologic isolated syndrome (RIS), initial serum and CSF NfL levels are associated with subsequent evidence of disease activity or clinical conversion.

Abstract
There are limited data about humoral response to vaccine in Behçet's syndrome (BS). We compared SARS-CoV-2 antibody response after two doses of inactivated (Sinovac/CoronaVac) or mRNA (Pfizer/BioNTech) vaccines in patients with BS and healthy controls (HCs). We studied 166 (92M/74F) patients with BS (mean age: 42.9 ± 9.6 years) and 165 (75M/90F) healthy controls (mean age: 42.4 ± 10.4 years), in a single-center cross-sectional design between April 2021 and October 2021. A total of 80 patients with BS and 89 HCs received two doses of CoronaVac, while 86 patients with BS and 76 HCs were vaccinated with BioNTech. All study subjects had a negative history for COVID-19. Serum samples were collected at least 21 days after the second dose of the vaccine. Anti-spike IgG antibody titers were measured quantitatively using a commercially available immunoassay method. We found that the great majority in both patient and HC groups had detectable antibodies after either CoronaVac (96.3% vs 100%) or BioNTech (98.8% vs 100%). Among those vaccinated with CoronaVac, BS patients had significantly lower median (IQR) titers compared to HCs [36.5 (12.5-128.5) vs 102 (59-180), p < 0.001]. On the other hand, antibody titers did not differ among patients with BS and HCs who were vaccinated with BioNTech [1648.5 (527.0-3693.8) vs 1516.0 (836.3-2599.5), p = 0.512). Among different treatment regimen subgroups in both vaccine groups, those who were using anti-TNF-based treatment had the lowest antibody titers. However, the difference was statistically significant only among those vaccinated with CoronaVac. Among patients vaccinated with BioNTech, there was no statistically significant difference between different treatment regimen groups. Compared to inactivated COVID-19 vaccine, mRNA-based vaccine elicited higher antibody titers among BS patients. Only in the CoronaVac group, patients especially those using anti-TNF agents were found to have low titers compared to healthy subjects. BS patients vaccinated with BioNTech were found to have similar seroconversion rates and antibody levels compared to healthy controls. Further studies should assess whether the low antibody titers are associated with diminished protection against COVID-19 in both vaccine groups.

Abstract
Background and purpose COVID‐19 is a novel infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) in which neurological complications have been increasingly recognized. Acute symptomatic epileptic seizures and status epilepticus are frequently reported neurological complications associated with this infection. The nervous system damage caused by SARS‐CoV‐2 may be mediated by the immune system. Interleukin 6 (IL‐6), an important component of the cytokine storm, is directly correlated with the severity of symptoms. Tocilizumab is an inhibitor of IL‐6 receptors, which blocks IL‐6‐mediated signal transduction and is used in the treatment of COVID‐19 and status epilepticus. Case report A patient with the Unverricht–Lundborg disease is presented who had developed refractory recurrent status epilepticus during COVID‐19 infection, which was finally controlled by treatment with tocilizumab. Discussion Tocilizumab, an IL‐6 inhibitor, may be considered as a treatment option in patients with status epilepticus and refractory seizures.

Abstract
BackgroundBehçet’s syndrome Overall Damage Index (BODI) is a newly developed damage index specific to Behçet syndrome (BS).ObjectivesWe aimed to evaluate validity, reliability and feasibility of the Turkish version of BODI and evaluate its performance for use in retrospective cohort studies for different phenotypes of BS.MethodsThe study included 295 patients with at least 3 visits at 6 months intervals out of 590 consecutive BS patients who were admitted between January 2015 and August 2017. Turkish version of the BODI form was developed by translating into Turkish and backwards by 2 people. BODI scores were calculated for each year during the follow-up period. The test-retest reliability of BODI was assessed by scoring the same 50 patients at 6-month intervals by the same observer (YYO). Two different observers (YYO- YO) assessed the same 50 patients for inter-observer agreement. The intra-class correlation coefficient (ICC) was used to assess the inter and intra-observer agreement. We also evaluated the median time to fill out the form in patients with different types of involvements.ResultsAmong the 295 (158 F/137 M) patients, mean age was 39 (9.9) and the mean disease duration was 8.8 (5.9) years. Clinical features of BS patients were summarized in the Table 1. BODI median score was 1 (IQR=0-1). We observed an increase in BODI score in 111 (38%) patients during follow-up. The main reasons for increasing BODI scores were eye, vascular and neurological involvement (Table 1). The mean ICC for inter-observer agreement was 0.94 (95% CI, 0.89-0.96) and for intra-observer agreement was 1. The median (range) time to complete the form was 2 (1-8) minutes.Table 1.Clinical features and BODI scores of Behçet syndrome patients.Oral ulceration99.7Genital ulceration81.3Erythema nodosum57.1Papulopustular lesions89.5Joint involvement25.2Ocular involvement47.3Vascular involvement21.4Neurologic involvement3.1Gastrointestinal involvement2.7N of patients with more than 3 BODI scores*(%)194 (66)Causes for increase in BODI score**(n=111) (%)Ocular involvement77 (69)Vascular involvement17 (15)Neurological involvement8 (7)Gastrointestinal involvement3 (3)Mucocutaneous inv.6 (5)Cardiovascular inv.1 (0.9)Diabetes mellitus4 (4)Avascular necrosis2 (2)Osteoporosis related fracture1 (0.9)*All patients had at least 3 BODI scores,**Some patients had more than 1 type of involvementConclusionThis study showed that the Turkish version of BODI was a reliable and feasible instrument that could capture the change over time in damage, and could be used in retrospective cohort studies.

Abstract
BackgroundInfliximab (IFX) is an effective therapeutic option in the management of severe and refractory manifestations of Behçet’s syndrome (BS).ObjectivesWe aimed to evaluate long term drug survival of IFX in a large cohort of BS patients.MethodsWe reviewed the charts of BS patients who received IFX between 2004 and June 2021 and noted demographic features, reasons for IFX use, IFX duration, and reasons for discontinuation.Results371 patients (290 men, mean age at IFX initiation: 35.5 ± 10 years) received IFX for uveitis (n=164), vascular involvement (n=114), central nervous system (CNS) involvement (n=55), arthritis (n=19), gastrointestinal (GI) involvement (n=15), mucocutaneous involvement (n=10), venous ulcers (n=13), and secondary amyloidosis (n=1). Twenty patients had more than one type of involvement requiring IFX.During a median follow-up of 30 months (IQR: 13-52), 175 (47%) patients were still receiving IFX for a median period of 40 months (IQR: 22-66) while 196 (53%) patients had discontinued IFX after a median follow-up of 19 months (IQR: 8-34).IFX retention rate was 50% for mucocutaneous involvement, 43% for uveitis, 49% for vascular involvement, 58% for CNS involvement, 37% for arthritis, 53% for GI involvement, and 31% for venous ulcer (Table 1).Table 1.Drug survival of infliximab and reasons for infliximab discontinuationMucocutaneous involvement (n=10)Uveitis (n=164)Vascular (n=114)CNS (n=55)Arthritis (n=19)GIS (n=15)Venous ulcer (n=13)Male (n, %)3 (30)127 (77)89 (78)49 (89)14 (74)9 (60)12 (92)Age at infliximab initiation (mean ± SD years)35.8 ± 9.334 ± 9.936 ± 9.136.2 ± 10.439.6 ± 10.743 ± 14.137.4 ± 8.2Number of patients who used concomitant immunosuppressives (n, %)5 (50)108 (66)86 (75)38 (69)5 (26)11 (73)7 (54)Duration of infliximab use (mean ± SD months)33 ± 3845 ± 3828 ± 2337 ± 2837 ± 3526 ± 2625 ± 25Number of patients who discontinued infliximab (n, %)5 (50)93 (57)58 (51)23 (42)12 (63)7 (47)9 (69)Due to remission-30212121Due to primary inefficacy157---5Due to secondary inefficacy212545--Due to adverse event1231211541Due to noncompliance11113--2Due to other reasons-1212311-Reasons for discontinuation were adverse events in 56 (15%), remission in 54 (15%) patients, inefficacy in 45 (12%) (secondary inefficacy in 26 (7%), primary inefficacy in 19 (5%)), and lack of patient compliance in 18 (5%). Other reasons were preparation for surgical operation (n=4), pregnancy (n=4), lack of health insurance (n=4), preferring subcutaneous administration during the pandemic (n=3), due to prison sentence (n=3), willing to get pregnant (n=1), rejecting the treatment (n=1), and death (n=3).Adverse events (n=56) leading to the cessation of IFX were infusion reactions (n=22), infections (n=7), tuberculosis (n=6), malignancy (n=6), palmoplantar psoriasis (n=5), hepatotoxicity (n=4), lichen planus (n=1), drug induced lupus (n=1), auricular chondritis (n=1), macrophage activation syndrome (n=1), splenic infarction (n=1) and a decrease in left ventricular ejection fraction (n=1).At the end of the follow-up, 2 patients had died due to lung adenocarcinoma, 1 patient had died due to pneumosepsis, 1 due to severe parenchymal neurologic involvement and 1 with pulmonary artery involvement due to massive hemorrhage during IFX treatment. Additionally, 7 patients had died 9, 10 months, 3, 3, 4, 7 and 9 years after IFX discontinuation. The causes of death were severe nervous system involvement in 2 patients, right heart failure due to pulmonary hypertension, laryngeal adenocarcinoma, lung adenocarcinoma, sepsis and gastrointestinal bleeding in 1 patient each.ConclusionIFX seems to be effective for the treatment of organ and life-threatening manifestations in the majority of the patients. However, drug retention rate was not optimal, mainly due to adverse events, inefficacy and patient non-compliance.Disclosure of InterestsSinem Nihal Esatoglu Speakers bureau: Sinem Nihal Esatoglu has received honorariums for presentations from UCB Pharma, Roche, Pfizer, and Merck Sharp Dohme, Beyza Tukek: None declared, Sitki Safa Taflan: None declared, Yilmaz Ozyazgan: None declared, Didar Ucar: None declared, Vedat Hamuryudan Speakers bureau: Vedat Hamuryudan has served as a speaker for AbbVie, Celgene, Novartis, and UCB Pharma, Grant/research support from: Vedat Hamuryudan has received grant/research support from Celgene., Yesim Ozguler Speakers bureau: Yesim Ozguler has received honorariums for presentations from UCB Pharma, Novartis, and Pfizer., Emire Seyahi Speakers bureau: Emire Seyahi has received honorariums for presentations from Novartis, Pfizer, AbbVie, and Gliead, Melike Melikoglu: None declared, Ugur Uygunoglu Speakers bureau: Ugur Uygunoglu has received speaker fees from F Hoffmann La-Roche, F Hoffmann La-Roche, Bayer, Merck-Serono, Novartis, Teva, and Biogen Idec/Gen Pharma of Turkey, Consultant of: Ugur Uygunoglu has received advisory board honorariums from F Hoffmann La-Roche, F Hoffmann La-Roche, Bayer, Merck-Serono, Novartis, Teva, and Biogen Idec/Gen Pharma of Turkey, Aksel Siva Speakers bureau: Aksel Siva received honorariums from Teva for speaking engagements., Consultant of: Aksel Siva received honorariums from Bayer-Schering AG, Biogen/Gen Ilac of Turkey, Genzyme, Merck-Serono, and Roche for consulting, fees from Novartis as a consultant and advisory committee member,., Grant/research support from: Aksel Siva received travel and registration reimbursements from Genzyme., Zekayi Kutlubay: None declared, Izzet Fresko: None declared, Sebahattin Yurdakul: None declared, Hasan Yazici: None declared, Gulen Hatemi Speakers bureau: Gulen Hatemi has served as a speaker for AbbVie, Celgene, Novartis, and UCB Pharma., Grant/research support from: Gulen Hatemi has received grant/research support from Celgene.

Abstract
BackgroundSince first emerged in December 2019, the COVID-19 pandemic has resulted in a death toll surpassing 5.5 million worldwide and had severe consequences on the global economy, environment, public health and social life [1, 2]. Multiple potential vaccines against COVID-19 have been developed swiftly and as shown in several phase 3 clinical trials, they demonstrated considerable efficacy without an unusual safety signal in healthy individuals.ObjectivesIn this study, we aimed to evaluate vaccine reactivity and disease flare following vaccination with either Sinovac/CoronaVac or Pfizer/BioNTech among BS and FMF patients compared with patients with various diagnosis of RD and healthy controls.MethodsOnly those patients and healthy controls who rece,ved at least one single shot of either CoronoVac or BioNTech against COVID-19 were included in the study. We tried to contact all of these patients and controls consecutively by telephone and attempted to make interviews with the eligible ones.ResultsWe studied the efficacy, side effects and disease flares after COVID-19 vaccination in 256 patients with Behcet’s syndrome (BS), 247 with familial Mediterranean fever (FMF), 601 with rheumatic diseases (RD) and 612 healthy controls (HC). Study participants were vaccinated either with CoronaVac (BS:109, FMF: 90, RD: 343, and HC: 334) or BioNTech (BS: 147, FMF:157, RD: 258 and HC: 278). BioNTech ensured a significantly better efficacy than CoronaVac against COVID-19 in all patient groups (BS: 1.4% vs 10.1%; FMF: 3.2% vs 12.2%, RD:2.7% vs 6.4%). Those with at least one adverse event (AE) were significantly more frequent among those vaccinated with BioNTech than those with CoronaVac (BS: 86.4% vs 45%; FMF: 83.4% vs 53.3%; RD: 83.3% vs 45.5% and HC: 86.3% vs 52.1%). The majority of AEs were mild to moderate and transient and this was true for either vaccine. There were also AEs that required medical attention in all study groups following CoronaVac (BS:5.5%, FMF:3.3%, RD:2.9% and HC:3.3%) or BioNTech (BS:5.4%, FMF:1.9%, RD:4.7% and HC:4.7%). The main causes for medical assistance were disease flare, and cardiovascular events. Disease flares after vaccination were significantly more frequent among BS (41/256; 16.0%) and FMF (43/247; 17.4%) patients compared to patients with RD (36/601; 6.0%). This was true for both CoronaVac (BS: 11.0%, FMF: 24.4% and RD: 5.2%, p<0.001) and BioNTech (BS: 19.7%, FMF: 13.4% and RD: 7.0%, p=0.001)(Table 1).Table 1.Flares among patients with Behçet’s syndrome, familial Mediterranean fever, rheumatic diseases after vaccination with CoronaVac and BioNTechCoronaVacBehçet’s syndrome,n=109Familial Mediterranean Fever,n=90Rheumatic diseases, n=343Flares, n (%)Flares, n (%)Flares, n (%)12 (11.0)22 (24.4)18 (5.2)BioNTechBehçet’s syndrome, n=147Familial Mediterranean Fever, n=157Rheumatic diseases, n=258Flares, n (%)Flares, n (%)Flares, n (%)29 (19.7)21 (13.4)18 (7.0)RA, Rheumatoid Arthritis; BS, Behçet’s syndrome; FMF, Familial Mediterranean FeverConclusionOur study demonstrates that BS and FMF patients vaccinated with either CoronaVac or BioNTech demonstrated almost similar AE profile and frequency compared to RD patients and HC. AEs that required physician consultation or hospitalization occurred in all study groups after either CoronaVac or BioNTech. Caution should be required when monitoring these patients after vaccination. Increased frequency of flares in BS and FMF compared to that seen in RD might reflect defects in innate immunity and deserves further investigation.References[1]https://covid19.who.int Accessed date 22.01.2022[2]Nicola M, Alsafi Z, Sohrabi C, Kerwan A, Al-Jabir A, Iosifidis C, Agha M, Agha R.

Emergence of New Manifestations During Infliximab Treatment in Behçet Syndrome. Rheumatology (Oxford) 2021; 61:3746-3753. [PMID: 34958357 DOI: 10.1093/rheumatology/keab944] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 12/10/2021] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES Infliximab (IFX) is being increasingly used for the treatment of severe manifestations of Behçet syndrome (BS). However, emergence of new manifestations has also been occasionally reported during IFX treatment. We aimed to assess the frequency of new manifestations in our BS patients treated with IFX. METHODS A chart review was conducted to identify all BS patients treated with IFX in our clinic between 2004 and 2020. Demographic data, indications for IFX initiation, concomitant treatments, and outcomes were recorded. A new manifestation was defined as the emergence of a new organ involvement or mucocutaneous manifestation developing for the first time during IFX treatment or within 12 weeks after the last infusion of IFX. RESULTS Among our 282 patients who used IFX, 19 (7%) patients had developed a total of 23 new manifestations during a mean follow up of 20.0 ± 15.3 months. Patients with vascular involvement were more likely to develop a new manifestation (12/19, 63%). Initial manifestations that required IFX were in remission at the time of new manifestation in 14/19 patients. IFX treatment was intensified (n = 6) and/or glucocorticoids, immunosuppressives, or colchicine were added to IFX (n = 21). IFX was switched to another agent for the remaining manifestations (n = 8). These treatment modifications led to remission in 17/19 patients. CONCLUSION New manifestations developed during IFX treatment in 7% of our patients with BS. They could be managed by intensifying IFX treatment or adding other agents in majority of these manifestations.

Abstract
Predicting treatment failure and switching effective treatment immediately in patients with multiple sclerosis (MS) is important. We aimed to evaluate the usefulness of Modified Rio score (MRS) in predicting treatment failure in MS patients. This is a retrospective study, which was conducted in two University Hospital. 129 MS patients treated with İnterferon or glatiramer-acetate from 2 clinical sites, were retrospectively selected. MRS was calculated after the first year of therapy. Treatment failure was defined as the presence of a 1 point increase in EDSS, 2 clinical attacks, 1 clinical attack and progression, 1 clinical attack and new lesion on MRI except associated with an attack, or new lesion in 2 different MRI taken at least 3 months apart. The sensitivity, specificity, positive and negative predictive values of the MRS in predicting treatment failure were determined. 71 (55%) patients with score '0', 41 (31.8%) patients with score '1', 11 (8.5%) patients with score '2', 6 (4.7%) patients with score '3' were detected. 14 patients needed treatment switching during the first three years of the treatment. Sensitivity was 57%, specificity was 92%, positive predictive value was 95%, negative predictive value was 47% and accuracy was 89%. Modified Rio score (MRS) was found to be effective in determining the treatment failure as mentioned before. This study will be useful for clinicians who evaluate the treatment failure like us, and this study revealed that the MRS may also help predict treatment failure.

Abstract
Background COVID-19 is a multisystemic infection with variables consequences depending on individual and comorbid conditions. The course and outcomes of COVID-19 during neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disorders (MOGAD) are not clearly known. Objective/methods The aim of this study was to examine the features and outcomes of COVID-19 infection in NMOSD and MOGAD patients. The patients' demographic and clinical factors, disease modifying treatment (DMT) used and disease information of COVID-19 infection were recorded. Conditions leading to hospitalization and severe exposure to COVID-19 infection were also analyzed. Results The study included 63 patients from 25 centers. Thirty-two patients (50.8%) belong to AQP-4 seropositive group, 13 (20.6%) and 18 (28.6%) were in MOG-positive and double-seronegative groups, respectively. Risk factors for severe COVID-19 infection and hospitalization were advanced age, high disability level and the presence of comorbid disease. Disease severity was found to be high in double-seronegative NMOSD and low in MOGAD patients. No statistically significant effect of DMTs on disease severity and hospitalization was found. Conclusion In NMOSD and MOGAD patients, advanced age, high disability and presence of comorbid disease pose risks for severe COVID-19 infection. There was no direct significant effect of DMTs for COVID-19 infection.

Abstract
Background
Multiple sclerosis (MS) has a complex pathophysiology, variable clinical presentation, and unpredictable prognosis; understanding the underlying mechanisms requires combinatorial approaches that warrant the integration of diverse molecular omics data.
Methods
Here, we combined genomic and proteomic data of the same individuals among a Turkish MS patient group to search for biologically important networks. We previously identified differentially-expressed proteins by cerebrospinal fluid proteome analysis of 179 MS patients and 42 non-MS controls. Among this study group, 11 unrelated MS patients and 60 independent, healthy controls were subjected to whole-genome SNP genotyping, and genome-wide associations were assessed. Pathway enrichment analyses of MS-associated SNPs and differentially-expressed proteins were conducted using the functional enrichment tool, PANOGA.
Results
Nine shared pathways were detected between the genomic and proteomic datasets after merging and clustering the enriched pathways. Complement and coagulation cascade was the most significantly associated pathway (hsa04610, P = 6.96 × 10−30). Other pathways involved in neurological or immunological mechanisms included adherens junctions (hsa04520, P = 6.64 × 10−25), pathogenic Escherichia coli infection (hsa05130, P = 9.03 × 10−14), prion diseases (hsa05020, P = 5.13 × 10−13).
Conclusion
We conclude that integrating multiple datasets of the same patients helps reducing false negative and positive results of genome-wide SNP associations and highlights the most prominent cellular players among the complex pathophysiological mechanisms.

Abstract
Background:Infliximab (IFX) is increasingly used in the management of severe, relapsing or refractory manifestations of Behçet Syndrome (BS). Emergence of de novo manifestations have been reported during IFX treatment, despite efficacy for the initial manifestation that required IFX use1.Objectives:We aimed to survey a sizeable cohort of BS patients treated with IFX for the development of de novo manifestations during treatment.Methods:A chart review was conducted to identify all BS patients who were given IFX in our Behçet Disease Research Center between 2004 and 2020. Demographic data, indications for IFX initiation, concomitant drugs, prior treatments, and outcomes were recorded. De novo manifestations were defined as new BS manifestations that had not occurred before IFX treatment.Results:A total of 252 patients used IFX with the main indications being uveitis in 122, vascular involvement in 82, parenchymal central nervous system involvement in 32, gastrointestinal involvement in 11, arthritis in 10, mucocutaneous involvement in 4, and secondary amyloidosis in 1. Of these patients, 17 (6%) had developed a total of 21 de-novo manifestations during a mean follow-up of 38.4 ± 92 (SD) months (Table 1). Vascular involvement was the main indication for IFX in the majority (n=12; 71%) of these 17 patients followed by eye involvement (n=3; 18%), central nervous system involvement (n=1), and joint involvement (n=1). Concomitant medications were prednisolone in 14 patients, azathioprine in 6 patients, mycophenolate mofetil, cyclosporine-A and methotrexate in 1 patient each. Thirteen patients (76%) were in remission for the main indication when de-novo manifestations emerged. In 10 patients IFX treatment was intensified either by increasing the dose to 10 mg/kg (2 patients) or by shortening the infusion intervals to 4 weeks (2 patients) along with the addition of corticosteroids or immunosuppressives. In the remaining 7 patients IFX was switched to another agent (cyclophosphamide in 5, adalimumab in 1 and anakinra in 1). At the time of this survey 8/17 patients were still on IFX for a mean follow-up of 32.5 ± 24.6 (SD) months, with concomitant low dose prednisolone in 5, azathioprine in 3 and mycophenolate mofetil in 3. In addition to the 7 patients who discontinued IFX at the time of de-novo manifestations, 2 more patients had discontinued IFX due to allergic reactions.Conclusion:De novo manifestations developed during IFX treatment in 6% of BS patients, despite efficacy for the initial manifestation. Appearance of de novo manifestations mostly in patients with vascular involvement is noteworthy. Intensification of IFX treatment was efficacious in managing de novo manifestations in more than half of these patients.References:[1]Hamuryudan V et al.

Abstract
Background:Infliximab (IFX) plays a key role in the management of severe and refractory manifestations of Behçet syndrome (BS). However we had previously shown that its sustained use may be limited due to adverse events and lack of patient compliance (1).Objectives:To assess the retention rate of IFX, adverse events, causes of discontinuation and outcome after cessation of IFX in a larger group of BS patients who were followed in a tertiary center.Methods:The charts of BS patients who were prescribed IFX between 2004 and 2020 were reviewed to determine demographic features, reasons for IFX use, previous and concomitant drugs, IFX duration, reasons for cessation of IFX and time to flare following cessation of IFX. Follow-up was censored on March 2020.Results:A total of 252 patients (195 men, mean age 40±10 years) received IFX for uveitis (n=122), vascular involvement (n=82), parenchymal neurologic involvement (n=32), gastrointestinal involvement (n=11), arthritis (n=10), mucocutaneous involvement (n=4), and secondary amyloidosis (n=1). Ten patients had more than 1 involvement requiring IFX.During a median follow-up of 52 (IQR: 30-88) months, 122 (48%) patients were still receiving IFX for a median period of 33 (IQR: 15-56) months while 130 (52%) patients had discontinued IFX after a median follow-up of 17 (IQR: 7-31) months. Reasons for discontinuation were remission in 25 (19%) patients, adverse events in 39 (30%), lack of efficacy in 23 (18%) (4 primary and 19 secondary), lack of patient compliance in 36 (28%), pregnancy in 4, and preparation for surgery in 3 patients.Adverse events (n=39) that required the cessation of IFX were infusion reaction (n=17), infection (n=7), hepatotoxicity (n=4), malignancy (n=4), palmoplantar psoriasis (n=3), lichen planus (n=1), drug induced lupus (n=1), splenic infarction (n=1), and a decrease in left ventricular ejection fraction (n=1).Among the 25 patients who discontinued IFX due to remission, 5 (20%) had a relapse after 4, 21, 26, 29, 38 and 46 months. The remaining patients did not experience a relapse during a median follow-up of 35 (IQR: 24-68) months.At the end of the follow-up, 2 patients had died due to lung adenocarcinoma during IFX treatment and 3 patients had died 1 year, 3 and 8 years after IFX discontinuation. The causes of death were with right heart failure due to pulmonary hypertension in 1, and severe nervous system involvement in 2 of the patients.Conclusion:Despite its successful use for the management of potentially organ and life-threatening manifestations in more than half of our patients with BS, long term maintenance was not possible in 42%, mainly due to adverse events, lack of patient compliance and inefficacy.Reference:[1]Esatoglu SN, Tukek B, Taflan SS, et al.

An uncommon disease included commonly in the differential diagnosis of neurological diseases: Neuro-Behçet's syndrome. J Neurol Sci 2021; 426:117436.

Abstract
Behçet's Syndrome (BS) may present with different neurological problems, related either directly (primary) or indirectly (secondary) to BS. Primary neurological involvement is named as neuro-Behcet's syndrome (NBS), and its two major subtypes that are classified mainly on the clinical and MRI findings are (1) Parenchymal-NBS (p-NBS) and (2) Extra parenchymal neuro-vascular involvement mostly seen as cerebral dural venous sinus thrombosis (CVST). The less commonly seen forms of NBS are cognitive and behavioral syndromes and peripheral nervous system involvement. Parenchymal-NBS is the most common clinical neurological presentation of BS. It is a rare disease with distinct MRI features and is often included in the differential diagnosis of neuro-vascular and neuro-inflammatory disorders. The most commonly affected neuro-anatomical site in p-NBS is the meso-diencephalic junction (MDJ), followed by the ponto-bulbar and thalamic regions, the basal ganglia, and the spinal cord. These varied locations may explain to a certain extent why BS is considered in the differential of so many neurological disorders. The other relatively common form of NBS that results in CVST may also be confused with other conditions resulting in CVST, especially when the systemic clinical features suggestive of BS are missed.

Abstract
It has been reported that multiple sclerosis (MS) is more common among patients with familial Mediterranean fever (FMF) than expected in normal population. Also, an association between MEFV gene variants and disease severity in MS has been described. Excessive production of interleukin-1 (IL-1) beta is responsible for FMF pathogenesis, and anti-IL-1 treatment is an effective approach in colchicine-resistant FMF patients. Here, we describe three patients with FMF and coexisting MS who have been treated with anti-IL-1 agents. Our observations suggest that blocking IL-1 is a safe and an effective alternative for colchicine resistant FMF and probably also for associated MS.

Abstract
Background:Nervous system involvement of Behçet syndrome (neuroBS) is a serious, but infrequent manifestation of Behçet syndrome (BS). Although many BS patients present with signs and symptoms related to the nervous system, several of these are diagnosed with conditions other than neuroBS. The differential diagnosis may be difficult in such patients.Objectives:To identify conditions mimicking neuroBS among patients with BS and to determine clinical, laboratory and imaging findings that may help the differential diagnosis.Methods:We retrospectively screened the charts of 500 BS patients who were registered to our clinic between February 2012 and April 2015, to identify those who were referred to neurology at any time during their follow-up. We follow our BS patients in a multidisciplinary clinic and all patients with a sign or symptom related to the nervous system are seen by one of the neurologist members of the clinic. The final diagnoses, as well as presenting signs and symptoms, laboratory and imaging results and results of any other diagnostic modalities were retrieved from patient charts. Patients who did not have a follow-up visit during the last 3 months were invited to the clinic for their final condition. Those who were not able to come, or one of their family members if they were not able to talk, were interviewed on the phone.Results:Among the 500 BS patients who were screened, 116 (23%) were referred to neurology (53 men, 63 women, mean age 32.8 (±9.8), 98 (84%) fulfilled ISG criteria). Among these, 29 (5.8%) were diagnosed with neuroBS, 30 (6%) had other conditions related to the nervous system, 46 (9.2%) were not diagnosed with a nervous system disorder and their symptoms disappeared and 11 (2.2%) were inconclusive and lost to follow-up. Of the 29 patients with neuroBS, 20 had parenchymal involvement, 7 had cerebral venous sinus thrombosis, 1 had concurrent parenchymal involvement and cerebral venous sinus thrombosis and 1 had atypical neuroBS. Of the 30 BS patients who were diagnosed with another nervous system condition, 14 (2.8%) had primary headache syndromes including tension type headache (n=5) and migraine (n=9), 6 (1.2%) had psychiatric disorders including psychotic disorder (n=1), depression (n=4) and somatization disorder (n=1), the remaining patients had other diagnoses which were entrapment neuropathy (n=2), epilepsy, glial tumor, multiple sclerosis, Meniere’s disease, optic neuritis, neuroretinitis, steroid myopathy and polyneuropathy in one patient each. Presentation features such as cerebellar symptoms, motor symptoms, visual problems, altered consciousness, seizure, fever and facial palsy were more common among patients with neuroBS, whereas sensory symptoms and isolated headache were more common among BS patients with other nervous system conditions (Table).Table.Clinical characteristics of patients with neuroBS versus other diagnosesClinical findings at presentationBS patients with nervous system involvement (neuroBS) (n=29)BS patients with other nervous system conditions (n=30)Only headache2 (7%)17 (56%)Cerebellar symptoms*8 (27%)4 (13%)Motor symptoms*4 (14%)2 (7%)Sensory symptoms*3 (10%)5 (17%)Visual problems*(diplopia, blurred vision)9 (31%)1 (3%)Cognitive symptoms*2 (7%)2 (7%)Other* (Alteration of consciousness, seizure, fever, facial palsy)9 (31%)1 (3%)* Accompanying more than 1 symptom/signConclusion:Nervous system conditions other than neuroBS are common in patients with BS who present with nervous system findings.

Abstract
Background:Infliximab (IFX) has become an important treatment option for all manifestations of Behçet syndrome (BS). Adverse events, loss of efficacy, lack of patient compliance and cost may limit its sustained use in patients with BS.Objectives:We aimed to evaluate the drug retention rates, causes of discontinuation and outcome after cessation of IFX.Methods:We reviewed the charts of 850 patients with BS who were registered in our clinic between 2009 and 2013 and identified those who had used IFX. The charts of these patients were surveyed for demographic features, the reasons for IFX use, previous and concomitant drugs, IFX duration, reasons for discontinuation and time to flare after discontinuation of IFX. We defined flare as disease activity in the organ involvement that necessitated IFX use. New major organ involvement that developed during or after discontinuation of IFX were also be noted.Results:A total of 50/850 patients were treated with IFX (40 men, mean age 40±9.5 years), for uveitis (n=29), vascular involvement (n=11), parenchymal neurologic involvement (n=8), arthritis (n=1) and venous ulcer (n=1). Of these 50 patients, 22 (43%) are still receiving IFX for a median duration of 40 (IQR: 25-83) months. The remaining 28 (47%) patients had discontinued IFX after a median follow-up of 12 (IQR: 7-30) months. Reasons for discontinuation were remission in 7 patients, adverse events in 10, primary lack of efficacy in 2, and lack of patient compliance in 9 patients. Among the 7 patients who discontinued IFX due to remission, only 1 patient with uveitis had a flare, 11 months after discontinuation, while on azathioprine. The remaining 6 did not experience any flares during a median follow-up of 29.5 (IQR: 4-24) months. Five of these patients used azathioprine and 1 used mycophenolate mofetil for maintenance. Among the 10 patients who discontinued due to adverse events, IFX was switched to adalimumab in 3 patients and none experienced flares under adalimumab. The remaining 7 patients continued to receive azathioprine or mycophenolate mofetil without a biologic. Among these, 1 patient with uveitis 1 with arthritis experienced flares 6 months after discontinuing IFX. Among the 9 patients who discontinued IFX due to lack of patient compliance, 3 patients (2 with uveitis and 1 with arthritis) had flares after 5 months, 1 year and 1.5 years. IFX was re-initiated in all. The remaining 6 patients did not experience any flares after a mean follow up of 5±1.5 years. Two with uveitis and 2 with venous thrombosis used azathioprine for maintenance, while 2 patients did not receive further treatment. New major organ involvement was not observed. New BS manifestations developed in 2 patients under IFX, arthritis in one patient and both epididymitis and erythema nodosum in the other.Conclusion:Almost half of our patients with BS remained on IFX during a median follow-up of 5.4 years (IQR:2.4-7). Main reasons for discontinuation were adverse events, remission and lack of patient compliance. Our observations further support the efficiency of IFX in managing patients with BS.Disclosure of Interests:Sinem Nihal Esatoglu: None declared, Beyza Tukek: None declared, Sitki Safa Taflan: None declared, Yilmaz Ozyazgan: None declared, Didar Ucar: None declared, Emire Seyahi: None declared, Melike Melikoglu: None declared, Vedat Hamuryudan Speakers bureau: Pfizer, AbbVie, Amgen, MSD, Novartis, UCB, Ugur Uygunoglu: None declared, Aksel Siva: None declared, Izzet Fresko: None declared, Sebahattin Yurdakul: None declared, Hasan Yazici: None declared, Gulen Hatemi Grant/research support from: BMS, Celgene Corporation, Silk Road Therapeutics – grant/research support, Consultant of: Bayer, Eli Lilly – consultant, Speakers bureau: AbbVie, Mustafa Nevzat, Novartis, UCB – speaker

Abstract
Multiple Sclerosis (MS) is an immune-mediated and neurodegenerative disease of central nervous system. Relapsing-remitting (RR)-MS occurring with acute attacks and remissions, is the most common clinical type of MS. There are different strategies applied in first-line treatment of RR-MS patients such as interferon-beta (IFN-β) and glatiramer acetate. In this study, activating and inhibitory receptor expressions and interleukin (IL)-22 levels of NK cells were investigated in RR-MS patients with or without IFN-β therapy. Activating receptor expression and IL-22 levels of NK cells were increased in RR-MS patients under IFN-β therapy. Elevated NK cells with activating profile and increased IL-22 under IFN-β therapy suggest that IFN-β treatment might direct NK cells toward a pro-inflammatory status.

Abstract
OBJECTIVES The efficacy and safety of biosimilar infliximab (bio-IFX) was shown in randomised controlled trials and it was approved for all indications of the reference product in several countries. However, a previous case series of 3 patients with Behçet's syndrome (BS) reported disappointing results. We aimed to share our experience with bio-IFX treatment in different types of organ involvement in patients with BS. METHODS We reviewed the charts of all BS patients who were prescribed reference infliximab (ref-IFX) or bio-IFX in our BS clinic. Among the 181 BS patients who were prescribed IFX since 2003, 6 (3%) were prescribed bio-IFX due to refractory disease despite conventional immunosuppressives. RESULTS A total of 6 patients (mean age: 32.1±6.2, mean disease duration: 5.3±1.8 years, 5 men and 1 woman) received bio-IFX for uveitis, nervous system, vascular and joint involvement. Four of the 6 patients obtained remission and stayed in remission during the 16±6.5 months they used bio-IFX. Among the 4 patients who obtained remission, 2 were switched to ref-IFX due to unavailability of bio-IFX infusion set and did not experience adverse events or loss of efficacy. However, relapses occurred during tapering. The other 2 patients are still in remission with bio- IFX. Among the remaining 2 patients, one had to be switched to ref-IFX after the first infusion, due to a change in the reimbursement policy and the other was non-responsive. CONCLUSIONS Our limited experience showed that bio-IFX may be a safe and effective alternative for patients with BS, refractory to conventional immunosuppressives.

Abstract
Background Steps towards the development of diagnostic criteria are needed for children with the radiologically isolated syndrome to identify children at risk of clinical demyelination. Objectives To evaluate the 2005 and 2016 MAGNIMS magnetic resonance imaging criteria for dissemination in space for multiple sclerosis, both alone and with oligoclonal bands in cerebrospinal fluid added, as predictors of a first clinical event consistent with central nervous system demyelination in children with radiologically isolated syndrome. Methods We analysed an international historical cohort of 61 children with radiologically isolated syndrome (≤18 years), defined using the 2010 magnetic resonance imaging dissemination in space criteria (Ped-RIS) who were followed longitudinally (mean 4.2 ± 4.7 years). All index scans also met the 2017 magnetic resonance imaging dissemination in space criteria. Results Diagnostic indices (95% confidence intervals) for the 2005 dissemination in space criteria, with and without oligoclonal bands, were: sensitivity 66.7% (38.4–88.2%) versus 72.7% (49.8–89.3%); specificity 83.3% (58.6–96.4%) versus 53.9% (37.2–69.9%). For the 2016 MAGNIMS dissemination in space criteria diagnostic indices were: sensitivity 76.5% (50.1–93.2%) versus 100% (84.6–100%); specificity 72.7% (49.8–89.3%) versus 25.6% (13.0–42.1%). Conclusions Oligoclonal bands increased the specificity of magnetic resonance imaging criteria in children with Ped-RIS. Clinicians should consider testing cerebrospinal fluid to improve diagnostic certainty. There is rationale to include cerebrospinal fluid analysis for biomarkers including oligoclonal bands in planned prospective studies to develop optimal diagnostic criteria for radiologically isolated syndrome in children.

Abstract
Background: Younger age, male sex and presence of spinal cord lesion(s) increase the risk of conversion from radiologically isolated syndrome (RIS) to relapsing-remitting multiple sclerosis (RRMS). Elevated cerebrospinal fluid (CSF) chitinase-3-like protein 1 (CHI3L1) levels predict conversion from clinically isolated syndrome (CIS) to RRMS. Objective: To evaluate the prognostic value of CSF CHI3L1 in RIS patients for conversion to RRMS. Methods: We compared CSF CHI3L1 concentrations in RIS, CIS, RRMS and symptomatic controls (SCs). We analysed the influence of epidemiological, radiological and CSF parameters on the risk of clinical event. Results: A total of 211 patients (71 RIS, 48 CIS, 50 RRMS and 42 SC) were included. CSF CHI3L1 levels were lower in RIS than in RRMS and higher in RIS with positive CSF versus negative CSF and SC. The presence of at least one spinal cord lesion was the only independent predictor of faster conversion to RRMS. Association of high CSF CHI3L1 levels, positive CSF (presence of oligoclonal bands and/or an elevated IgG index) or four Barkhof criteria with any spinal cord lesion showed a tendency for reduced mean conversion time. Conclusion: CSF CHI3L1 correlates with positive CSF but is not an independent predictor of the risk of conversion from RIS to RRMS.

Abstract
Objective: To describe clinical and radiologic outcomes of children with incidental findings on neuroimaging suggestive of CNS demyelination (termed “radiologically isolated syndrome” or RIS). Methods: Clinical and radiologic data were obtained from a historical cohort of children with no symptoms of demyelinating disease who had MRI scans that met the 2010 MRI criteria for dissemination in space for MS. Results: We identified 38 children (27 girls and 11 boys) with RIS now being prospectively followed at 16 sites in 6 countries. The mean follow-up time was 4.8 ± 5.3 years. The most common reason for initial neuroimaging was headache (20/38, 53%). A first clinical event consistent with CNS demyelination occurred in 16/38 children (42%; 95% confidence interval [CI]: 27%–60%) in a median of 2.0 years (interquartile range [IQR] 1.0–4.3 years). Radiologic evolution developed in 23/38 children (61%; 95% CI: 44%–76%) in a median of 1.1 years (IQR 0.5–1.9 years). The presence of ≥2 unique oligoclonal bands in CSF (hazard ratio [HR] 10.9, 95% CI: 1.4–86.2, p = 0.02) and spinal cord lesions on MRI (HR 7.8, 95% CI: 1.4–43.6, p = 0.02) were associated with an increased risk of a first clinical event after adjustment for age and sex. Conclusions: We describe the clinical characteristics and outcomes of children with incidental MRI findings highly suggestive of CNS demyelination. Children with RIS had a substantial risk of subsequent clinical symptoms and/or radiologic evolution. The presence of oligoclonal bands in CSF and spinal cord lesions on MRI were associated with an increased risk of a first clinical event.

Abstract
Behçet’s syndrome (BS) is a multisystem vasculitis that presents with a variety of mucocutaneous manifestations such as oral and genital ulcers, papulopustular lesions and erythema nodosum as well as ocular, vascular, gastrointestinal and nervous system involvement. Although it occurs worldwide, it is especially prevalent in the Far East and around the Mediterranean Sea. Male gender and younger age at disease onset are associated with a more severe disease course. The management of BS depends on the severity of symptoms. If untreated, morbidity and mortality are considerably high in patients with major organ involvement. Multidisciplinary patient care is essential for the management of BS, as it is for other multisystem diseases. Rheumatologists, dermatologists, ophthalmologists, neurologists, cardiovascular surgeons and gastroenterologists are members of the multidisciplinary team. In this study, we reviewed the epidemiology, etiology, diagnostic criteria sets, clinical findings and treatment of BS and highlighted the importance of the multidisciplinary team in the management of BS.

Abstract
BACKGROUND The study was a collaboration between Lifting The Burden (LTB) and the European Headache Federation (EHF). Its aim was to evaluate the implementation of quality indicators for headache care Europe-wide in specialist headache centres (level-3 according to the EHF/LTB standard). METHODS Employing previously-developed instruments in 14 such centres, we made enquiries, in each, of health-care providers (doctors, nurses, psychologists, physiotherapists) and 50 patients, and analysed the medical records of 50 other patients. Enquiries were in 9 domains: diagnostic accuracy, individualized management, referral pathways, patient's education and reassurance, convenience and comfort, patient's satisfaction, equity and efficiency of the headache care, outcome assessment and safety. RESULTS Our study showed that highly experienced headache centres treated their patients in general very well. The centres were content with their work and their patients were content with their treatment. Including disability and quality-of-life evaluations in clinical assessments, and protocols regarding safety, proved problematic: better standards for these are needed. Some centres had problems with follow-up: many specialised centres operated in one-touch systems, without possibility of controlling long-term management or the success of treatments dependent on this. CONCLUSIONS This first Europe-wide quality study showed that the quality indicators were workable in specialist care. They demonstrated common trends, producing evidence of what is majority practice. They also uncovered deficits that might be remedied in order to improve quality. They offer the means of setting benchmarks against which service quality may be judged. The next step is to take the evaluation process into non-specialist care (EHF/LTB levels 1 and 2).

Deficient prepulse inhibition of blink reflex in migraine and its relation to allodynia. Neurophysiol Clin 2016; 47:63-68. [PMID: 27771197 DOI: 10.1016/j.neucli.2016.09.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 09/21/2016] [Indexed: 10/20/2022] Open
Abstract
OBJECTIVE Prepulse inhibition (PPI) of the blink reflex (BR) is a reduction in BR excitability due to a conditioning stimulus, reflecting sensory gating by brainstem structures. We aimed to analyze PPI changes during a painful episode in chronic or episodic migraine and its relation to allodynia, since abnormal brainstem filtering has been hypothesized in migraine pathophysiology. METHODS We included 20 patients with migraine during headache episode, and age- and gender-matched 22 healthy subjects. We recorded BR after unconditioned and conditioned supraorbital stimuli. For conditioned stimuli, we applied preceding subthreshold stimulus to the median nerve at wrist. The presence of PPI was compared between the two groups, as well as the specific BR parameters (latency, amplitude or area of R1 and R2 components) in unconditioned (test) and conditioned (PPI) paradigms. RESULTS In the patient group, seven (35%) patients did not have R2-PPI whereas all healthy subjects had R2-PPI (P=0.003). Healthy subjects displayed significantly increased R1 amplitude and reduced R2 amplitude and area after conditioned stimuli. In migraine patients, we observed significant reduction only in R2 amplitude. Logistic regression demonstrated that allodynia was independently related with the presence of PPI (beta: -0.535, P=0.021). CONCLUSIONS Our study provides evidence for sensory gating impairment at brainstem level in migraine headache, related to the presence of allodynia.

Infliximab is a plausible alternative for neurologic complications of Behçet disease. NEUROLOGY-NEUROIMMUNOLOGY & NEUROINFLAMMATION 2016; 3:e258. [PMID: 27458602 PMCID: PMC4950829 DOI: 10.1212/nxi.0000000000000258] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/07/2016] [Accepted: 05/18/2016] [Indexed: 11/15/2022]
Abstract
Objective: We evaluated the effectiveness of infliximab in patients with neuro-Behçet syndrome for whom other immunosuppressive medications had failed. Methods: Patients whose common immunosuppressive medications fail in recurrent neuro-Behçet syndrome need an alternative. We report our experience with the tumor necrosis factor α blocker infliximab for long-term treatment of neuro-Behçet syndrome. We recruited patients within a multidisciplinary referral practice of Behçet disease and prospectively followed everyone with a neurologic symptom(s). Patients (n = 16) with ≥2 neurologic bouts (excluding purely progressive disease) while on another immunosuppressive treatment were switched to and successfully sustained on infliximab (5 mg/kg in weeks 0, 2, and 6, then once every 8 weeks; minimum follow-up duration ≥12 months). Infliximab was stopped within 2 months after initiation in one patient because of pulmonary and CNS tuberculosis. Results: Patients had stepwise worsening due to relapses in the Expanded Disability Status Scale modified for neuro-Behçet syndrome before switching to infliximab (median score of 5.0, range 2.0–7.0; median neuro-Behçet syndrome duration 29.1 months, range 5.0–180.7). Median duration of preinfliximab immunosuppressive medication use was 20.0 months (range 3.0–180.7). In all 15 patients, during infliximab treatment (median score 4.0, range 2.0–7.0; median duration 39.0 months, range 16.0–104.9 months), neurologic relapses were completely aborted and there was no further disability accumulation. Conclusion: We observed a significant beneficial effect of infliximab in neuro-Behçet syndrome. Classification of evidence: This study provides Class IV evidence that for patients with neuro-Behçet syndrome whose other immunosuppressive medications failed, infliximab prevents further relapses and stabilizes disability.

Migraine incidence in 5 years: a population-based prospective longitudinal study in Turkey. J Headache Pain 2015; 16:103. [PMID: 26634568 PMCID: PMC4669335 DOI: 10.1186/s10194-015-0589-2] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2015] [Accepted: 11/30/2015] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND The incidence of migraine has been investigated only in a few studies worldwide and it is not known in our country. We, therefore, aimed to estimate the migraine incidence in a previously accomplished population-based prevalence study sample of 5323 individuals in the year 2008. METHODS The former Turkish headache prevalence study has been completed as a nationwide, randomized, home-based study of face-to-face examination by physicians trained for headache diagnosis by using ICHD criteria. Five years after this study an optimized survey including 50 questions was performed to estimate the migraine incidence in migraine-free individuals in the previous study, with a 56.4 % responder rate. Two validation studies for this survey were performed prior and after the study each in 100 subjects by comparing the gold standard of expert diagnosis of headache, showing high rate of reliability (Crohnbach alpha: 0.911 and 0.706, respectively). RESULTS Migraine incidence was estimated as 2.38 % (2.98 % in women and 1.93 % in men) per year in 2563 migraine-free individuals; if the population at risk is defined as the group without any headaches, the migraine incidence decreased to 1.99 %. The chronic migraine (CM) incidence [without medication overuse (MOH)] was 0.066 % and that of MOH was 0.259 %. We found a significant burden of the disease on the occupational functionality as well as on social and family life, even in the early years of the migraine. The family history of headaches especially in the fathers could be useful to predict new cases of migraine, besides the well-known risk factor, diagnosis of depression, whereas income and education did not seem to relate to migraine onset. CONCLUSIONS Our study with a large population-based nation-wide sample, using ICHD-II criteria, with structured headache interviews as well as blinded re-validation of the questionnaire diagnoses showed a 2.38 % incidence rate of migraine in Turkey, higher than most of the other previous reports; a finding which could be related to genetic factors and also to the methodological differences in the study designs. Moreover the incidence of CM was found to be 0.066 %.
