Abstract
Introduction. Recent instrumentation and software advancement enabled to develop new, high‑throughput targeted metabolomics methods for in‑depth exploration of metabolome in a quantitative manner.Material and Methods. The presented targeted metabolomics approach allows to analyze both of serum and CSF in the same way, with identical sample preparation procedures. The analyses were carried out using high‑performance liquid chromatography system coupled to triple quadrupole tandem mass spectrometer with electrospray ion source (LC‑ESI‑QqQ‑MS/MS). Results. The applied targeted metabolomics approach enabled to determine a wide panel of metabolites from different chemical classes of compounds including: acylcarnitines, amino acids and biogenic amines, glycerophospholipids, sphingolipids and sum of hexoses. Finally, 148 metabolites in serum and 57 in cerebrospinal fluid were determined.Conclusions. Here we presented the results of successful implementation of the method of analysis of low‑molecular weight compounds in human serum and CSF using targeted metabolomics. The evaluation of selected groups of metabolites resulted in obtaining the mean concentrations of panel of metabolites in serum and CSF, which gives a valuable information about the metabolome of these matrices.

Association of platelet-derived microvesicles and their phenotypes with carotid atherosclerosis and recurrent vascular events in patients after ischemic stroke. Thromb Res 2019; 176:18-26.

Abstract
INTRODUCTION Platelet-derived microvesicles (pMVs) exhibit procoagulant and proinflammatory properties and play a role in the development and progression of atherosclerosis. The study examined the association between the total number of pMVs and their phenotypes with carotid atherosclerosis and recurrent vascular events (VEs) in patients in the convalescent phase of ischemic stroke (IS). MATERIALS AND METHODS The study group consisted of 72 patients with IS secondary to large artery atherosclerosis (LAA) (n = 40) and small arteries occlusion (SAO) (n = 32) and 69 matched cardiovascular disease risk-factor (RF) controls. Total pMV number, defined as CD61+ microvesicles (MVs), and their phenotypes, defined as the surface expression of proinflammatory (CD40L, CD62P, CD31) and procoagulant (PS, PAC-1) markers, were characterized and quantified using flow cytometry. The mean common carotid intima-media thickness (CCA mean IMT), maximal common carotid IMT (CCA max IMT) and maximal bifurcation IMT (BIF max IMT) were measured bilaterally using B-mode, color Doppler ultrasonography. All study subjects were observed for one-year to establish the occurrence of VEs. RESULTS No differences in pMV parameters between LAA and SAO stroke subjects and between stroke subgroups and controls were found. Stroke patients with carotid atherosclerosis exhibited higher concentration of CD62P+/CD61+ and PAC-1+/CD61+ MVs compared to patients without the atherosclerosis. Positive associations between total number of pMVs, AnV+ MVs and AnV+/CD61+ MVs and atherosclerotic thickening of carotid intima-media in stroke patients were found. Elevated concentration of AnV+/CD61+, PAC-1+/CD61+, CD61P+/CD61+ and CD31+/CD61+ MVs, were revealed in stroke patients who suffered from recurrent VE in one-year follow-up period. Negative correlation of pMVs and CD62P+/CD61+ MVs concentration as well as percentage of total CD61+ in AnV+ population of MVs and time elapsed from IS in convalescent stroke subjects was revealed. CONCLUSION Our results confirm positive correlations between total pMV number, the number of PAC-1+/CD61+ and CD62+/CD61+ MVs and carotid atherosclerosis in stroke subjects. Some pMV parameters may exhibit a predictive value for the next VE in groups with a history of stroke. pMVs and some of their phenotypes decline over time elapsed from stroke in convalescent stroke subjects.

Abstract
Cluster headache (CH) is a rare trigeminal autonomic cephalalgia. Although its pathophysiology is not entirely understood, the hypothalamus and trigeminal nociceptive and autonomic pathways seem to play a key role in its pathology. In the majority of cases, CH begins at a young age and affects mainly men. This article presents a case of a 76-year-old woman with CH that developed at the age of 74. This is one of the first documented reports of CH with such atypical features from an epidemiologic point of view. A possibility of symptomatic cluster-like headache (CLH) attributed to cerebrovascular disease in the patient is also discussed.

Abstract
Alzheimer’s disease (AD) is a progressive disease, with frequently observed improper biothiols turnover, homocysteine (Hcy) and glutathione (GSH). GSH protects cells from oxidative stress and may be determined by 8-oxo-2’-deoxyguanosine (8-oxo2dG) level and its repair enzyme 8-oxoguanine DNA glycosylase (OGG1). The presence of unfavorable alleles, e.g., in APOE cluster, TOMM40 or APOC1 is known to facilitate the dementia onset under oxidative stress. The aim of the study was to analyze rs1052452, rs2075650 TOMM40 polymorphisms, rs4420638 APOC1, and their correlation with Hcy, GSH, 8-oxo2dG, OGG1 levels in plasma of AD patients and controls. We recruited 230 individuals: 88 AD, 80 controls without (UC), 62 controls with (RC) positive family history of AD. The TOMM40 genotype was determined by HRM and capillary electrophoresis, while APOC1 by HRM. The concentrations of OGG1, 8-oxo2dG were determined by ELISA, whereas Hcy, GSH by HPLC/EC. We showed that over 60% of AD patients had increased Hcy levels (p<0.01 vs. UC, p<0.001 vs. RC), while GSH (p<0.01 vs. UC), 8-oxo2dG (p<0.01 vs. UC, p<0.001 vs. RC) were reduced. Minor variants: rs10524523-L, rs4420638-G, rs2075650-G were significantly overrepresented in AD. For rs4420638-G, rs2075650-G variants, the association remained significant in APOE E4 non-carriers. The misbalance of analyzed biothiols, and 8-oxo2dG, OGG1 were more pronounced in carriers of major variants: rs10524523-S/VL, rs4420638-A, rs2075650-A. We showed, for the first time, that APOC1 and TOMM40 rs2075650 polymorphisms may be independent risk factors of developing AD, whose major variants are accompanied by disruption of biothiols metabolism and inefficient removal of DNA oxidation.

Abstract
Although neurons are the main source of neurotrophins in the healthy brain, neurotrophins can also be expressed in the immune system. We have previously shown that in relapsing-remitting multiple sclerosis (RRMS) lower immune-cell neurotrophin levels are associated with brain atrophy and cognitive impairment. The aim of the present study was to assess if immune-cell neurotrophin expression is impaired in MS as compared with the healthy controls, and to describe if these levels change in treatment-naïve RRMS patients, following one year of immunomodulation. Fifty treatment-naïve RRMS patients were assessed at baseline and after one year of immunomodulation (beta-interferons/glatiramer acetate). The control group included 39 healthy subjects matched according to age and gender. Peripheral blood mononuclear cells (PBMCs) were isolated from heparinized blood using Ficoll-Histopaque gradient. The levels of brain-derived-neurotrophic-factor (BDNF), beta-nerve-growth-factor (beta-NGF), neurotrophin-3 (NT-3) and neurotrophin-4/5 (NT-4/5) were measured in PBMC lysates with ELISA. BDNF levels were significantly lower in MS than in the healthy controls (median 613 vs. 1657pg/mg protein, p<0.001). After one year of immunomodulation, BDNF expression did not change significantly (p=0.06) on the group level. In 70% of patients there was no increase in BDNF level, and in 30% it increased. We observed no differences between treatment groups. Other neurotrophins were detected in a minority of MS samples (as opposed to the controls). To conclude, we have shown that immune-cell production of neurotrophins is impaired in MS patients. In our MS cohort standard immunomodulation failed to restore normal BDNF levels in PBMCs within one year of therapy.

Abstract
SummaryBinding of fibrinogen to platelets washed from blood of migraine patients (n = 30) and control donors (n = 24) was compared. In addition, contents of platelet glycoprotein IIb and platelet fibrinogen were determined in both groups by radioimmunoassay. The receptor capacity for fibrinogen in platelets activated by ADP was significantly higher (p <0.01) in migraine patients (52,505 α 4,925) than in controls (33,881 λ 3,965). The mean contents of GPIIb (3.51 α 0.34 μg/108 platelets) and fibrinogen (37 .26 α 4.05 μg/108 platelets) in migraine platelets were also markedly increased (p <0.01 and p <0.001, respectively) when compared to controls (2.21 α 0.18 μg of GPIIb ano 18.75 λ 2.29 μE of fibrinogen per 108 platelets, respectively). There was a high correlation between the number of fibrinogen receptors exposed by ADP and the total amount of platelet GPIIb both in migraineurs (R = 0.69, p <0.01) and controls (R = 0.62, p <0.01,), as well as plasma cholesterol in the case of migraine patients (R = 0.82, p <0.001)

Abstract
Platelet-derived microvesicles (pMVs) are small, heterogeneous vesicles released from platelet membranes as a result of activation. These microvesicles possess a wide range of properties, including prothrombotic, proatherogenic, proinflammatory, immunomodulatory, and even anticoagulant activity. The elevated release of these microvesicles has been observed in various metabolic, inflammatory, thrombotic, and vascular diseases, including ischemic heart disease, stroke, hypertension, diabetes, and connective tissue disease. Modulation of both pMV generation and the expression of their surface molecules may have beneficial clinical implications and could become a novel therapeutic target. However, mechanisms by which pharmacological agents can modify pMV formation are elusive. The purpose of this review is to discuss the effects of drugs routinely used in primary and secondary prevention of vascular disease on the release of pMV and expression of their surface procoagulant and proinflammatory molecules.

Abstract
Differentiation of systemic lupus erythematosus (SLE) from multiple sclerosis (MS) can be challenging, especially when neuropsychiatric (NP) symptoms are accompanied by white matter lesions in the brain. Given the lack of discriminative power of currently applied tools for their differentiation, there is an unmet need for other measures that can aid in distinguishing between the two autoimmune disorders. In this study we aimed at exploring whether brain atrophy measures could serve as markers differentiating MS and SLE. Thirty-seven relapsing-remitting MS and 38 SLE patients with nervous system manifestations, matched according to age and disease duration, underwent 1.5 Tesla magnetic resonance imaging (MRI), including volumetric sequences, and clinical assessment. Voxelwise analysis was performed using ANTS-SyN elastic registration protocol, FSL Randomise and Gamma methods. Cortical and subcortical segmentation was performed with Freesurfer 5.3 pipeline using T1-weighted MPRAGE sequence data. Using MRI volumetric markers of general and subcortical gray matter atrophy and clinical variables, we built a stepwise multivariable logistic diagnostic model to identify MRI parameters that best differentiate MS and SLE patients. We found that the best volumetric predictors to distinguish them were: fourth ventricle volume (sensitivity 0.86, specificity 0.57, area under the curve, AUC 0.77), posterior corpus callosum (sensitivity 0.81, specificity 0.57, AUC 0.68), and third ventricle to thalamus ratio (sensitivity 0.42, specificity 0.84, AUC 0.65). The same classifiers were identified in a subgroup analysis that included patients with a short disease duration. In MS brain atrophy and lesion load correlated with clinical disability, while in SLE age was the main determinant of brain volume. This study proposes new imaging parameters for differential diagnosis of MS and SLE with central nervous system involvement. We show there is a different pattern of atrophy in MS and SLE, and the key structural volumes that are differentially affected include fourth ventricle and posterior section of corpus callosum, followed by third ventricle to thalamus ratio. Different correlation patterns between volumetric and clinical data may suggest that while in MS atrophy is driven mainly by disease activity, in SLE it is mostly associated with age. However, these results need further replication in a larger cohort.

Abstract
Migraine is one of the most common primary headache disorders that affects 11% of the adult population. The disease is divided into two main clinical subtypes: migraine with aura (MA) and migraine without aura (MO). Both serotonergic and hypocretinergic systems are involved in the migraine pathomechanism. Polymorphisms in the serotonin transporter gene (SLC6A4) and the hypocretin receptor 1 gene (HCRTR1) may be risk factors for migraine development due to their ability to affect serotonin and hypocretin-1 (HCRT-1) concentrations. The aim of the study was to analyze, for the first time in the Polish population, the 5-HT transporter linked polymorphic region (5-HTTLPR) in SLC6A4, G1222A (rs2271933) and the never before studied *G29A (rs41263963) polymorphisms in the HCRTR1 gene, as well as the 5-HT and hypocretin-1 plasma concentrations in migraine patients (MA, MO) and control subjects. The study included 123 patients that were diagnosed with migraine and 123 control subjects. Methods such as PCR, HRMA and sequencing were used for genotyping, while 5-HT was determined by HPLC/EC and hypocretin-1 by ELISA. No significant differences were observed in 5-HTTLPR frequencies. The A allele of HCRTR1 G1222A occurred more often in MO, while the GA genotype of HCRTR1 *G29A was more frequent among MA when compared to control group (p < 0.05). The mean age of migraine onset in individuals with HCRTR1 *G29A was 18 years old for patients with MA and 26 years old for MO patients. The localization and type of HCRTR1 polymorphisms (G1222A-missense variant in exon 7, *G29A-3'UTR variant) may predispose patients to the clinical subtype of migraine: MO or MA, respectively. In control subjects, the short allele of 5-HTTLPR tended to decrease the 5-HT concentration, while the A allele of HCRTR1 G1222A decreased both 5-HT and hypocretin-1 levels. Serotonin concentrations differed in terms of clinical features of migraine. The relation between genotypes of 5-HTTLPR, HCRTR1 G1222A, and 5-HT concentrations may bedisturbed in migraine. It seems that HCRTR1 *G29A is more strongly associated with regulating the 5-HT in patients with MA than MO, and therefore may contribute to the early age of onset for migraine.

Abstract
Abstract
Paraneoplastic movement disorders are rare, autoimmune-mediated, nonmetastatic complications of malignant neoplasms. Common paraneoplastic movement disorders include paraneoplastic chorea, dystonia, cerebellar degeneration, different types of encephalitis, opsoclonus-myoclonus syndrome, stiff person syndrome, and neuromyotonia. Syndromes usually develop before tumor diagnosis, have subacute onset, and are associated with serum or cerebrospinal fluid antibodies. Two types of antibodies can be distinguished: antibodies against nuclear and cytoplasmic neuronal antigens (anti-Hu, anti-Ri, anti-Yo, anti-Ma, anti-CV2/CRMP5, anti-Gephrin, and anti-GABATRAP) and antibodies recently identified against cell surface and synaptic proteins (anti-NMDAR, anti-LGI1, and anti-Caspr2). These two types differ from each other in a few important aspects. Antibodies against cell surface and synaptic protein disrupt cell-surface antigens. Clinical symptoms are related to the disruption of antigens and potentially can be reversed by immunotherapy. The association between these antibodies and malignancy is much less consistent. On the other hand, antibodies against nuclear and cytoplasmic neuronal antigens seem to be not pathogenic; however, they most likely indicate a T-cell-mediated immune response against neurons. Due to T-cell-mediated neuronal loss, response to immunotherapy is generally disappointing. Early recognition of all these diseases is crucial because it may lead to the disclosure of occult cancer. This review is focused on paraneoplastic movement disorders with emphasis on clinical presentations, investigational findings, and therapeutic results.

Abstract
The role of the thyroid gland in ischemic stroke pathology is not well understood. As thyroid hormones modulate the extracellular matrix, we explored the possible link between them and secreted protein acidic and rich in cysteine like 1 (SC1) - one of the extracellular matrix molecules. In the 81 patients with acute ischemic stroke, serum SC1 levels were much higher compared with 30 control subjects: 4.47 vs 2.43ng/mL (p<0.001). Serum levels of free thyroxine (fT4) were higher in stroke subjects compared to those of controls (p=0.03). In stroke patients, TSH concentration was lower than in the control group (p=0.03). SC1 levels positively correlated with fT4 levels (p=0.02) and negatively with TSH (p=0.03) in stroke patients. Our results confirmed the association between thyroid hormones and SC1 - extracellular matrix protein.

Abstract
SummaryLeptin is an adipokine that in vitro enhances agonist-induced platelet aggregation and adipokine expression. Hyperleptinaemia represents a risk factor for cardiovascular disease. We conducted a prospective evaluation of the potential link between blood platelet activation and plasma leptin levels in post-stroke patients. Using five-colour flow cyto-metry, the platelet surface expression of CD40L, CD62P, the subpopulations of monocyte-platelet aggregates and platelet-derived microparticles (PMPs) as well as the plasma leptin, soluble leptin receptor (sOb-R), leptin/sOb-R ratio, the plasma adiponectin, and leptin/adiponectin ratio were assessed in 98 stroke patients on the first (V0), 10th (V1) and 90th (V2) day after stroke and once in 78 age-, gender- and vascular risk factor-matched disease controls. We demonstrated that at V0 leptin resistance, defined as leptin/sOb-R ratio, was higher than in the controls [1.1 (0.5–1.8 vs. 0.5 (0.2–1.1); p=0.02]. After adjustment according to the factors which influence platelet activation, we confirmed the relationship between percentage of circulating PMPs and plasma leptin level (B=0.18; p=0.02) or the leptin/sOb-R ratio (B=0.23; p=0.02) in normal-weight subjects in the acute phase of stroke. No correlation could be demonstrated between the adipokine parameters and the percentage of monocyte-platelet aggregates or expression of platelet pro-inflammatory glycoproteins. In conclusion, formation of PMPs on the first day following an ischaemic stroke shows a positive correlation with leptin levels and with resistance to leptin. Leptin level does not seem to affect the expression of platelet surface proinflammatory glycoproteins.

Abstract
Alzheimer's disease (AD) is a multifactorial disease with genetic (70%) and environmental (30%) causes. Among the genetic factors are genes associated with a family history of the disease (familial AD, FAD) and sporadic AD (SAD). The genes: APP (amyloid precursor protein), PSEN1 (Presenilin 1) and PSEN2 (Presenilin 2) are responsible for the presence of FAD. The APOE gene is responsible for the sporadic form of the disease. Other molecular factors related to the immunological cause (TREM2) of the disease are a disorder of the lipid (ABCA1, ABCA7) or biothiol (MTHFD1) metabolism and of the transport of metabolites (BIN1). Currently, it is believed that APOE is a risk factor for both SAD and late-onset FAD. The pathomechanism of AD is most commonly explained as based on the amyloid cascade theory. This theory is related to the FAD, although there are reports indicating the probability of its occurrence in the SAD. It seems that the excessive deposition of β-amyloid (Aβ) peptides and intracellular neurofibrillary tangles of tau protein hyperphosphorylated forms contribute to the damage of both DNA and RNA. Furthermore, it is believed that RNA-interference can affect both the level of pathological proteins (Aβ, tau protein) and the onset and progress of AD. It seems that a complete understanding of both FAD and SAD pathogenesis may contribute to the search for earlier clinical diagnosis and to an understanding of later occurrence of the disease, which may help modify its course and affect more effective therapy of this incurable neurological disease.

Abstract
Cognitive impairment is a significant clinical problem both in multiple sclerosis (MS) and systemic lupus erythematosus (SLE) patients. In MS cognitive dysfunction has been associated with brain atrophy and total demyelinating lesion volume. In SLE cognitive impairment is much less understood, and its link to structural brain damage remains to be established. The aim of this study was to identify the relationship between subcortical gray matter volume and cognitive impairment in MS and SLE. We recruited 37 MS and 38 SLE patients matched by age, disease duration and educational level. Patients underwent magnetic resonance imaging (MRI) and a battery of psychometric tests. Severity of cognitive impairment was similar in both cohorts despite larger white matter lesion load in MS patients. Psychometric scores were associated with global and subcortical gray matter atrophy measures and lesion load in MS, but not in SLE. In SLE, the lack of a relationship between cognitive impairment and structural damage, defined either as atrophy or white matter lesions, indicates a different causal mechanism of cognitive deficit.

Abstract
Introduction The impact of choroid plexus with its blood–cerebrospinal fluid barrier in the ischemic stroke pathology is poorly explored. Transthyretin (TTR) is a protein synthesized in liver and just in choroid plexus. Objectives The current study was designed to assess the prognostic value of serum TTR for functional outcome (at the time of hospital discharge) and long-term (one-year) overall mortality in ischemic stroke patients. Patients and methods We conducted a prospective observational study. Patients (n = 81) with acute (< 24 hours of symptoms onset) ischemic stroke consecutively admitted to Stroke Unit were included. An unfavorable outcome was defined as a modified Rankin Scale (mRS) score ≥ 3. The relationships between serum TTR levels and clinical outcome were analyzed using multivariate analysis. One-year mortality was analyzed by Kaplan–Meier survival curves stratified by mean value of TTR. Results Compared with patients with mRS <3, patients with an unfavorable outcome at hospital discharge had significantly lower TTR levels on admission (P < 0.0001). In non-survivals serum TTR levels were significantly lower compared with patients who survive one year of observation (P = 0.009). Using multivariate analysis, transthyretin emerged as an independent predictor for unfavorable outcome at the day of hospital discharge (adjusted odds ratio = 0.96; 95% CI: 0.9–0.99, P <0.05). A one-year mortality of patients with the lower TTR levels was significantly higher than in patients with TTR levels above mean value (P = 0.02). Conclusions Serum level of TTR at admission was a predictor of functional outcome after ischemic stroke and was also associated with one-year mortality in stroke survivals.

Abstract
The purpose of this study was to determine the concentration of plasma norepinephrine (NE), epinephrine (E), and serotonin (5-HT) in two collections, after a 30-min supine (I) and 5-min upright position (II), and polymorphisms of genes, COMT (c.649G>A), MAO-A (c.1460C>T), and NET (c.1287G>A), in patients with Parkinson's disease (PD) and other degenerative parkinsonism and controls. The study was performed in 49 PD patients, 19 parkinsonism patients, and 48 controls. The level of NE, E, and 5-HT was determined by HPLC/EC. PCR-RFLP was conducted to analyze the COMT, MAO-A, and NET polymorphisms. Genotypes of COMT, MAO-A, and NET genes occurred with different frequencies in patients with movement disorders and controls. NET AA occurred 4.8 times more frequently in patients with parkinsonism than in PD (p < 0.05). COMT AA genotype was associated with increased E levels [E (I) p < 0.01, E (II) p < 0.05] in PD compared to controls. Patients with parkinsonism with MAO-A TT genotype have a significantly higher level of 5-HT [5-HT (II), p < 0.05] compared to controls. Moreover, PD patients with NET GA genotype have the lowest level of NE (p < 0.05) compared to controls. It appears that COMT, MAO-A, and NET polymorphisms and levels of NE, E, and 5-HT are involved in pathogenesis of PD.

Abstract
Adhesion molecules are involved in nerve growth, synaptic plasticity and myelin formation and maintenance process. Neural cell adhesion molecule (CD56 or NCAM) seems to play a crucial role in all the above-mentioned events. Having found poly-sialylated NCAM increased re-expression on demyelinated axons within multiple sclerosis plaques we assessed soluble NCAM (sNCAM) in sera of patients with various types of peripheral nerve affections - demyelinating, axonal "inflammatory", axonal metabolic polyneuropathies and healthy controls. These data were compared with the clinical state using Overall Neuropathy Limitations Scale (ONLS) and nerve conduction studies. We found significantly increased sNCAM concentration in demyelinating polyneuropathies in comparison to axonal group and healthy controls as well as significantly increased sNCAM level in axonal group in comparison to healthy subjects. We also found high positive correlation between sNCAM and ONLS and strong negative correlation between sNCAM level and the lowest conduction velocity (Vmin) found in a patient. We conclude that sNCAM might be thought as a specific marker of peripheral nerve demyelination and as a sensitive marker of peripheral nerve injuries.

Abstract
OBJECTIVE Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) remains poorly understood. Damage within the CNS is driven by the autoimmune response; however, immunopathophysiology of neuropsychiatric (NP) SLE is multifactorial. Immune cell neurotrophin production could be neuroprotective against autoimmunity-driven CNS damage, as has been shown in multiple sclerosis. The aim of this study was to establish whether immune cell neurotrophin production is associated with damage severity in NPSLE. METHODS Selected neurotrophins (BDNF, NGF, NT-3, and NT-4/5) were measured with ELISA within peripheral blood mononuclear cells (PBMCs) isolated from 38 NPSLE patients matched with 39 healthy controls. Subcortical and cortical structure volumes were segmented with the Freesurfer 5.3 pipeline on T1-weighted isotropic images acquired on a 1.5-T MRI scanner. RESULTS BDNF and NGF levels in PBMCs were reduced in NPSLE compared to the healthy population. The PBMC BDNF level was associated with reduced thalamus, caudate, and putamen volumes. The NGF level correlated with lateral ventricles enlargement and thalamic volume loss. CONCLUSIONS In NPSLE, immune cell BDNF and NGF levels are linked with subcortical atrophy. Higher BDNF levels are associated with higher midsagittal atrophy, which may reflect compensatory mechanisms, upregulating BDNF when neuroprotection is needed. These data require further confirmation.

Abstract
Aim. Ischemia‑modified albumin (IMA) is a marker of myocardial ischemia and may be affected by ischemia occurring in other tissues. Migraine has been reported as a risk factor of ischemic stroke or cardiovascular events. Dysfunction of endothelial cells, as well as association with arteriopathies was evidenced in migraine patients. The aim of this study was to evaluate interictal IMA in migraine patients.Material and Methods. Fifty migraineurs aged 38 ± 9 years were included in the study. The control group consisted of 25 healthy volunteers aged 37 ± 8 years. In all subjects neurological examination was carried on, as well as clinimetric evaluation with the use of: MIDAS, MIGSEV, QVM, VAS and VRS. Ischemia‑modified albumin was evaluated by means of spectrophotometric method with the use of cobalt chloride. The concentrations of total cholesterol, HDL- and LDL‑cholesterol, triglycerides, homocysteine, C‑reactive protein and Lp(a) were analyzed with routine spectrophotometric methods.Results. IMA was significantly (P = 0.0108) higher in migraine patients (0.101; 0.00–0.327 O.D.) than in controls (0.00; 0.00–0.102 O.D.; median; interquartile range). Migraineurs with aura have also higher IMA than controls. IMA correlated (rS = 0.383, P = 0.0073) with VAS and with homocysteine concentration (rS = 0.430, P = 0.0026). Multiple regression analysis of IMA and atherosclerosis risk factors showed significant correlation (P = 0.0247) with HDL cholesterol (R = 0.2958) and triglycerides concentrations (R = 0.3285).Conclusions. IMA formation in migraine patients, as a marker of oxidative stress even during interictal period in patients with hyperhomocysteinemia and/or hypertriacylglyceridemia can reflect a milieu of factors which further increases the risk for cardiovascular complications.

Abstract
Platelet-Endothelial-Cell-Adhesion-Molecule-1 (PECAM-1) and Human-Vascular-CAM-1 (VCAM-1) are adhesion molecules involved in leukocyte-endothelial interaction. In our study serum levels of sPECAM-1 and sVCAM-1 were measured (ELISA) in twenty-nine patients during their first monosymptomatic optic neuritis (ON) episode. Anti-aquaporin-4-antibodies (AQP4-IgG) were detected with the cell-based assay. Patients were followed for seven years, during which 16/24 AQP4-IgG (-) patients developed MS and 2/5 AQP4-IgG (+) patients developed NMO. Patients who developed MS had significantly lower sPECAM-1 and sVCAM-1 than those who did not. Serum sPECAM-1 and sVCAM-1 may turn out to be useful biomarkers correlated with the risk of progression to MS after first ON incident.
