AB  - Background: Recent literature data highlights metabolic changes in amyotrophic lateral sclerosis (ALS). To explore possible early metabolic changes, we aimed to analyse the fatty acids (FA) composition of erythrocytes in newly diagnosed als patients and to see whether fatty acid levels correlate with the ALSFRS-R score or disease duration. Methods: The severity of motor function involvement was assessed by the ALSFRS-R scale at the initial evaluation. The fatty acid profile of erythrocyte membranes was analysed by gas-liquid chromatography. The study comprised 26 clinically diagnosed als patients, with mean ALSFRS-R 38±8. The control group included 26 healthy volunteers. Results: Significantly higher levels of palmitic acid and total saturated FAs were detected in als patients. In als patients, total monounsaturated FA, palmitoleic, vaccenic, and oleic acid were also significantly increased. The levels of eicosapentaenoic acid, docosapentaenoic acid, total polyunsaturated FA (PUFA) and n-6 PUFA were significantly lower in als patients. Additionally, a-linolenic acid, the precursor of the n-3 PUFA family, was not detected in als patients. We found no significant correlation between the ALSFRS-R score and the abundance of individual FAs analysed. A moderate negative correlation was found between disease duration and DHA level, and a positive correlation was detected with MUFA. Conclusion: Experimental evidence presented may contribute to shaping a beneficial nutritional intervention.

AB  - The size of circulating immune complexes (CICs) in rheumatoid arthritis (RA) could be an emerging criterion in disease diagnosis. This study analyzed size and electrokinetic potential of CICs from RA patients, healthy young adults, and RA patients age-matched controls aiming to establish their unique CIC features. Pooled CIC of 30 RA patients, 30 young adults, and 30 RA group's age-matched controls (middle-aged and oldеr healthy adults), and in vitro IgG aggregates from pooled sera of 300 healthy volunteers were tested using dynamic light scattering (DLS). Size distribution of CIC in healthy young adults exhibited high polydispersity. RA CIC patients and their age-matched control showed distinctly narrower size distributions compared with young adults. In these groups, particles clustered around two well-defined peaks. Particles of peak 1 were 36.1 ± 6.8 nm in RA age-matched control, and 30.8 ± 4.2 nm in RA patients. Particles of peak 2 of the RA age-matched control's CIC was 251.7 ± 41.2 nm, while RA CIC contained larger particles (359.9 ± 50.5 nm). The lower zeta potential of RA CIC, compared to control, indicated a disease-related decrease in colloidal stability. DLS identified RA-specific, but also age-specific distribution of CIC size and opened possibility of becoming a method for CIC size analysis in IC-mediated diseases.

AB  - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, affecting motor neurons, which is characterized by the progressive loss of motor function. Sufficient evidence has been gathered, either in the form of experimental results from animal disease models or from the assessment of affected human subjects, which implicates metabolic changes in the course of ALS. Hypermetabolism, abnormal glucose tolerance and dyslipidaemia were reported to have high incidence in ALS patients. In fact, according to published studies, BMI is significantly and inversely associated with ALS progression. Here, we discuss basic principles of fatty acid metabolism, composition and the existing knowledge of metabolic and fatty acid composition changes in ALS patients. Literature data suggest that ALS patients have unfavorable changes in the fatty acid profile, especially because of the low level of long-chain polyunsaturated fatty acids. Nutritional interventions and supplementation with various foods or food supplements are currently not showing conclusive results, implying there is more to learn about potential ways to modify this illness.

AB  - Increased interest in microbiota calls for the thorough analysis of antibody reactivity to different microorganisms. As salivary IgA represents the first line of defence against microorganisms contacting mucosal surfaces, we explored the binding and specificity of salivary IgA by testing the binding of purified, FITC-labelled salivary IgA to different microorganisms in flow cytometry and conclude that this kind of analysis enables the differentiation of species/strains with high IgA binding capacity, which should be corroborated on a larger sample size. Further we compare, with in-house ELISA, the binding of polyclonal salivary IgA with the binding of polyclonal serum IgA from the same individuals to whole microbial cells and to purified microbial components. High correlations were obtained in total salivary IgA binding to Lactobacillus rhamnosus and Escherichia coli, very distant bacterial species, as well as to isolated bacterial components (r = .70–.97). The binding of total salivary IgA resembled the binding of both salivary IgA1 and IgA2, with IgA2 predominating. For serum polyclonal IgA repertoire, substantially higher specificity was obtained. Serum IgA binding to E. coli correlated best with serum IgA binding to lipopolysaccharide (r = .86), and serum IgA against L. rhamnosus correlated best with the anti-peptidoglycan IgA levels (r = .88). We have also detected that total serum IgA response is governed by either IgA1 or IgA2 response, depending on the nature of the antigen/s. We conclude that steady state salivary IgA repertoire, unlike serum IgA repertoire, consists of polyreactive antibodies with innate specificity, questioning its capacity to select resident microbiota.

AB  - S. pneumoniae is an important human pathogen which has a polysaccharide capsule with virulent properties. This work aims to estimate the titres of S. pneumoniae specific IgG and IgA isotypes, with respect to age and sex. An in-house whole bacterial cell ELISA was used for the determination of relative levels and endpoint titres of IgG subclasses and IgA1 subclass specific for S. pneumoniae serogroup 1, and to quantify specific IgG1 and IgG2 levels. Significantly lower anti-pneumococcus IgG1 titres were found in older individuals, which was more pronounced in men. Lower IgG2 titres were detected in men over 50 years of age, in comparison to women under 50 years of age. The levels of IgG3 and IgG4 did not differ between different sex and age groups. Lower IgA1 levels were detected in male individuals in both age groups in comparison to females under 50 years of age. The levels of IgG1 showed a moderate correlation with IgG4 in younger individuals of both sexes (r = 0.61 in men and 0.63 in women) which was not noted in the older age group. We highlight the deficiency in humoral immunity in older people, especially male and suggest immunization of this population with pneumococcal vaccines.

Significantly lower anti-pneumococcus IgG1 titres were found in older individuals, which was more pronounced in men. Lower IgG2 titres were detected in men over 50 years of age, in comparison to women under 50 years of age. The levels of IgG3 and IgG4 did not differ between different sex and age groups. Lower IgA1 levels were detected in male individuals in both age groups in comparison to females under 50 years of age. The levels of IgG1 showed a moderate correlation with IgG4 in younger individuals of both sexes (r = 0.61 in men and 0.63 in women) which was not noted in the older age group. We highlight the deficiency in humoral immunity in older people, especially male and suggest immunization of this population with pneumococcal vaccines.",

AB  - West Nile virus (WNV) is a zoonotic mosquito-borne virus classified as family Flaviviridae and genus Flavivirus. The first WNV outbreak in humans in the Republic of Serbia was recorded in 2012. Equids and dogs can show clinical symptoms after WNV infection and are often used as sentinels. This study aimed to (i) give insight into seropositivity for WNV in clinically healthy dog and horse sera in different regions of Serbia and (ii) compare diagnostic value of ‘in-house’ and commercially available indirect immunofluorescence (IFA) and enzyme-linked immunoassay (ELISA) tests to ‘gold standard’ virus neutralization test (VNT). Due to cross-reactivity, sera were tested for Usutu virus and tick-borne encephalitis virus in VNT based on the epidemiological data of field presence. Blood sera of dogs (n = 184) and horses (n = 232) were collected from 2011 to 2013. The seropositivity was confirmed by VNT in 36.9 % tested dog sera and 34.9% tested horse sera with highest positivity in regions near two big rivers, while in four dog and seven horse sera, positivity resulted from Usutu virus infection. Comparative results of diagnostic tests in dogs ranged from 18.7 % seropositivity by ‘in-house’ ELISA to 31.9% by commercially available ELISA. In horses, seropositivity ranged from 36.2% by ‘in-house’ IFA to 32.5% by commercially available IFA and from 26.3% by ‘in-house’ IgG ELISA to 20.9% by commercially available ELISA. There were no statistically significant differences according to the McNemar test between ‘in-house’ and commercially available IFA and ELISA test in horse sera, while the same was not true for two ELISAs used in dog sera (χ2 = 8.647, p = .003). Established seropositivity in dogs and horses was in accordance with the epidemiological situation and WNV spread in the Republic of Serbia and proven Usutu virus co-circulation. ‘In-house’ tests remain a valuable tool in early diagnostics of WNV.
