Abstract Introduction: The detection of intrathecal IgA synthesis (IAS) in multiple sclerosis (MS) is cumbersome, for this reason, we developed a highly sensitive assay to assess it in MS. Methods: 151 MS patients and 22 controls with different neurological diseases were recruited. IgA concentration was analyzed by ELISA. Oligoclonal IgA bands to detect IAS were determined by a new ultrasensitive assay based on isoelectrofocusing (IEF). Results: Most individuals showed an IgA concentration within normal range in serum samples (95.95%) but 38.41% of individuals had a low IgA concentration in the cerebrospinal fluid (CSF), with no significant differences observed between MS and control groups, neither in CSF nor in serum. The new IEF was more sensitive than those previously described (0.01 mg/dl of IgA), and clearly identified patients with and without IAS, that was not related with IgA concentration. MS patients showed higher percentage of IAS (43.00%) than the control group (18.20) (p = 0.035), because the incidence was especially higher in MS patients with clinically isolated syndrome (CIS, 66.00%). Conclusions: Intrathecal IgA synthesis is observed more frequently in MS patients than in other neurological diseases, and with higher incidence than assumed in the past.

Mycotoxins exposure by inhalation and/or dermal contact is possible in different branches of industry especially where heavily dusty settings are present and the handling of dusty commodities is performed. This study aims to explore the validity of the biomonitoring as a tool to investigate the intake of mycotoxins in a population of workers operating in an Italian feed plant. Serum samples were collected for the determination of aflatoxins B1 (AFB1), AFB1-Lysine adduct and ochratoxin A (OTA). A method based on liquid–liquid extraction coupled with high resolution mass spectrometry determination was developed and fully validated. For AFB1, a high number of non-detected samples (90%) was found and no statistical difference was observed comparing workers and control group. None of the analyzed samples showed the presence of AFB1-Lysine adduct. For OTA, the 100% of the analyzed samples was positive with a 33% of the samples showing a concentration higher than the limit of quantification (LOQ), but no statistical difference was highlighted between the average levels of exposed and control groups. In conclusion, the presence of AFB1 and OTA in serum cannot be attributable to occupational exposure.

We previously demonstrated that angiotensin II acts as a crucial neuroprotective factor after neural injury through angiotensin II type-2 (AT2) receptor signaling. Although the pathway is known to play an important role in the development of experimental autoimmune encephalomyelitis, cerebrospinal fluid (CSF) angiotensin II levels in patients with multiple sclerosis (MS) have never been studied. To clarify the significance of angiotensin II in MS, we assayed angiotensin II concentrations using an established enzyme-linked immunoabsorbent assay in CSF samples from patients with MS ( n = 21), patients with inflammatory neuropathies (IN) ( n = 23) and control individuals who did not have either of the neurological diseases or any other disease that might affect the angiotensin II levels in the CSF (control) ( n = 24). Angiotensin II levels in the CSF were 3.79 ± 1.54 pg/ml in the MS group, 5.13 ± 2.27 pg/ml in the IN group and 6.71 ± 2.65 pg/ml in the control group. The angiotensin II levels in the CSF of the MS group were significantly lower than in the control group ( p = 0.00057). Angiotensin II concentration in the CSF tended to have a negative correlation with the Kurtzke’s Expanded Disability Status Scale scores during MS relapse ( p = 0.0847). These findings suggest that reduced levels of intrathecal angiotensin II may be related to the abnormal neural damage and repair processes in MS.

Background: Gut microbiota cluster into three enterotypes named the Bacteroides, Prevotella and Ruminococcus. While each person’s microbial “fingerprint” is unique, there are specific patterns seen in those that are healthy and those that have specific illnesses. The aim of the present study is to identify the enterotypes that are likely related to Multiple Sclerosis Egyptian patients as well as their possible role in the course of the disease. Subjects & Methods: Thirty patients with remitting relapsing multiple sclerosis, who presented to the MS Clinic of Alexandria University Hospital were enrolled in our study. These were diagnosed according to according to McDonnald 2017 criteria. A cross matching control group of 20 healthy subjects of similar age and sex were included. Stool specimens were taken from each. Quantitative SYBR Green Real-Time PCR was done for the identification and quantitation of Bacteroides, Prevotella and Ruminococcus which constitute the core of the three major enterotypes. Results: Enterotype 1 is the most common enterotype detected in MS and control cases (80% versus 65%). For Enterotype 3, it was not detected in any of the 20 control cases while detected in multiple sclerosis case (16.7%). However, by comparing the multiple sclerosis and control cases Enterotype 2 is significantly less in multiple sclerosis than control (3.3% versus 35%). Conclusion: Although Enterotype 2 is significantly less in multiple sclerosis patients, collapsing the whole microbiome variations into dominant enterotypes was not appropriate to identify disease association or to be used as a disease biomarker.

Background/Aim. Multiple Sclerosis (MS) is a chronic neurological disease associated with low serum levels of 25-hydroxyvitamin D [25(OH)D]. The aim of this study was to determine the association between serum levels of 25(OH)D and the latitude as well as clinical MS severity and progression expressed by expanded disability status scale (EDSS) and multiple sclerosis severity score (MSSS). Methods. A total of 196 patients, from North and South of Montenegro, aged 18 to 65 years, with confirmed diagnosis of MS were recruited for the study. Serum samples were collected for 25(OH)D measurement. Control group consisted of 196 health controls, randomly selected from medical staff employed in health centers from three cities in North and Clinical Centre of Montenegro from the South. Results. The serum levels of 25(OH)D were significantly lower in MS patients compared to controls (p < 0.001). The serum levels of 25(OH)D were significantly different in regard to gender, with women showing lower levels. Although in the entire group of patients there was no statistical correlation between the levels of 25(OH)D and their residence, the significantly higher levels of 25(OH)D were detected in men from the North compared to women. The course of the disease had an impact on the 25(OH)D serum levels. 25(OH)D levels also significantly correlated with clinical parameters of both, disability (Spearman''s r = -0.23, p = 0.001) and progression (Spearman''s r = -0.25, p = 0.0004) of MS. Conclusion. Serum levels of 25(OH)D were associated with disability and progression in MS patients. Lower levels of 25(OH)D were detected in female patients from the North. The low level of 25(OH)D cannot be solely explained with unfavorable latitude and insufficient sun exposure, therefore further genetic analysis is needed.

Abstract Backgrounds: Multiple Sclerosis (MS) is a chronic inflammatory and autoimmune disease linked to several inflammatory and dietary parameters. This study was carried out to determine the relationship between serum leptin, orexin-A, and TGF-β levels with BMI in MS patients.Methods and results: In this cross-sectional study, 25 relapsing-remitting multiple sclerosis (RRMS) patients and 40 healthy controls were enrolled. The serum level of Leptin, Orexin-A, and TGF- were measured by the Enzyme-linked immunosorbent assay (ELISA). The data was analyzed using descriptive statistics, t-test, Chi-square test, and Linear regression test. A total of 65 volunteers, including 25 MS patients and 40 healthy, were enrolled in the study. The mean age of individuals in the case and control groups was 38.04 ± 7.53 and 40.23 ± 5.88. There were no statistically significant differences between the case and control groups regarding gender, age, alcohol, and cigarette use (P>0.05). The mean serum levels of Orexin-A and TGF-ß were lower among multiple sclerosis patients than in healthy controls, but leptin was higher (42.8 vs. 18.9 ng/ml, P<0.001). The relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among Multiple Sclerosis patients was not statistically significant (P > 0.05).Conclusion: Our results showed that the serum levels of Orexin-A and TGF-β were significantly lower. The serum level of leptin was higher among multiple sclerosis patients than among healthy controls. Also, there was no statistically significant relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among multiple sclerosis patients.

Sccmec Types

Background: Asymptomatic nasal colonization of Methicillin-Resistant Staphylococcus aureus is common in Multiple Sclerosis patients. SCCmec types I to III are mainly attributed to HA-MRSA strains whereas SCCmec types IV and V have commonly been reported in CA-MRSA infections. Here, we assessed the frequency of nasal carriage of MRSA in MS patients. This study aimed to evaluate MRSA SCCmec typing in MS nasal carriage. Methods: A cross-sectional descriptive study was conducted from Feb and Jun 2017 in MS Research Center, Tehran University of Medical Sciences (TUMS), Iran. Overall, 620 nasal swabs were collected (325 from MS patients and 295 from control group). Antimicrobial susceptibility test was performed using the disk diffusion and E-test method. Presence of mecA gene was confirmed by PCR assay and multiplex PCR was performed for SCCmec typing of MRSA isolates. Results: The frequency of MRSA among the MS patients and control group was almost equal (9.2% and 10.1%, respectively). SCCmec typing detected only types III, IV and V in both groups and type IV was the most predominant type in MS patients and control group. SCCmec type III was more prevalent in control group than MS patients (40% vs. 20%). Moreover, the frequency of SCCmec type V in MS patients was significantly higher than control group (36.7% vs. 3.3%). Conclusion: Although most MRSA isolates were collected from inpatients, interestingly there is a high frequency of SCCmec types IV and V in MS group. Moreover, MRSA isolates were not resistant to more antibiotics in SCCmec type III than types IV-V.

Background Adherence to multiple sclerosis (MS) disease-modifying drugs (DMDs) is essential for realization of their optimal effectiveness and benefits. Objective To evaluate the usefulness and validity of a smartphone-based e-diary as a tool for adherence assessment as well as its effectiveness as a promoter of adherence to DMDs. Methods An MS tailored e-diary (MyMS&Me) reminded patients to take their DMDs on time. DMD intake was self-recorded in the e-diary by the participants. Three methods of adherence evaluation were compared: e-diary derived, retrospective self-reported, and the medication possession rate (MPR). The proportion of patients with poor adherence to DMDs (defined as MPR <80%) among e-diary users was compared with a control group without intervention. Results Sixty-two patients downloaded the e-diary (Female: 41 (66%), Expanded Disability Status Scale 3.2 ± 2.2) and 55 controls were enrolled. The median difference between e-diary-derived adherence and the MPR was –3% (95% limits of agreement: −53% to 12%). The median difference between retrospective self-reported adherence and the MPR was 0.3% (95% limits of agreement: −20% to 42%). The proportion of participants with poor adherence to DMDs was similar in the e-diary and control groups (10% vs. 13%, p = 0.6). Conclusions Substantial and clinically important disagreement between methods of medication adherence evaluation was noted. Smartphone reminders did not significantly improve the MPR of DMDs.

Background Multiple sclerosis (MS) is a chronic neuroinflammatory disease characterized by inflammation involving the peripheral nerves. Shear wave elastography (SWE) is potentially a method of choice for detecting peripheral nerve involvement. Purpose To compare the degree of thickening and nerve elasticity of brachial plexus (BP) nerve roots and evaluate the usefulness of sonoelastography in patients with clinically diagnosed MS without brachial plexopathy. Material and Methods Thirty-two patients with MS and 32 controls were included in the study. Bilateral C5, C6, and C7 mean nerve root diameters, and mean elasticity values in kiloPascal (kPa) were measured in the patient and control groups. The relationship between the age, height, and weight values and nerve diameter-elasticity values of the patient and control groups was compared. Results The elasticity values of the C5 and C6 nerve roots were increased, and the nerve root thickness was decreased in the MS group compared to that in the control ( P < 0.05). There was no difference between the C7 mean nerve root elasticity (kPa) and diameter measurements in the patient and control groups ( P > 0.05). Conclusion Our study showed an increase in the BP nerve root elasticity values (kPa) in patients with MS compared to that of the control group and a decrease in diameter values thought to be related to the possible chronic atrophic process. The results are consistent with the demyelinating process of the peripheral nervous system (PNS) due to MS.
