The aim of the study was to evaluate the effectiveness of ribonucleic acid in the correction of immune disorders in patients with infectious mononucleosis (IM) caused by EBV. Materials and methods. We examined 110 patients with a mean age of 23.3±4.2 years with IM, among whom women accounted for 52.7 % (n=58). The material for the study was the serum of patients obtained during the disease course. The set of tests of patients with IM included clinical and biochemical methods, enzyme-linked immunosorbent assay, polymerase chain reaction method, immunogram. Statistical processing of the obtained data was performed with “Statsoft Statistica v. 10.0 for Windows” using the methods of variation and correlation statistics. Results. The obtained results analysis revealed changes in the system of cellular and humoral parts of the immune system and the diversity of the immune response in patients with IM. The progressive nature of changes in immune parameters indicated the formation of secondary cellular immune imbalance, activation of the humoral link, a change in the balance of immunoregulatory mediators towards Th2 cells. Significant changes in the cellular immune system were observed in the acute period and were characterized by the increase in the number of cells with killer activity, namely mature T-lymphocytes (CD3+), cytotoxic T-suppressor cells (CD8+), cells expressing the activation marker CD25+ (IL-2 receptor), and by the Th1/Th2 ratio increase. The appointment of combination therapy including ribonucleic acid was accompanied by immunomodulatory and antiviral effects, that was reflected in a more pronounced positive dynamics of immunological parameters, namely in strengthening the proliferative response, compared with the group of patients receiving only basic therapy. Conclusion. The expediency of the combination therapy application: the drug Nuclex (ribonucleic acid) (250 mg) 2 capsules 3 times a day for 14 days and valacyclovir (500 mg) at a dose of 1000 mg (2 tablets) 3 times a day for 14 days, is justified for the correction of immune disorders in patients with IM caused by EBV.

Abstract Recombinant human erythropoietin (rHuEPO) is a well-known treatment for anemia in multiple myeloma (MM) patients. We have previously reported that rHuEPO treatment was associated with prolonged survival of several patients suffering from advanced disease (Mittelman et al., 1997). Recently we have demonstrated that treatment of MM patients with rHuEPO is associated with significant improvements of certain immunological parameters and functions (Prutchi-Sagiv et al., 2006), mainly related to the cellular compartment. The objective of the present retrospective study was to determine whether rHuEPO treatment, in addition to its effects on the cellular immune compartment, also modulates the humoral arm of the immune system in MM patients. Medical charts of eighteen consecutive IgG and IgA MM patients were analyzed and the levels of normal immunoglobulins (Ig) and M-protein before and during rHuEPO treatment were recorded. We have found a significant increase in the levels of normal Ig (IgG, IgA and IgM) in response to rHuEPO, during the 3–9 months fromtreatment initiation. Importantly, the levels of M-protein remained stable for a period of 10–12 months from treatment initiation. These results are in line with previous studies, including our study in murine models (Katz et al., 2007), demonstrating that EPO improves humoral immune responses. The current study highlights the concept that EPO’s immunomodulatory actions on MM patients might also involve the humoral compartment of the immune system.

Background: Recurrent miscarriages are common complications in pregnancy. Neopterin is one of the immunologic biomarkers of several diseases related to activation of the cellular immune system. RSA is associated with immune system related abnormalities.Objectives: We aimed to investigate the effectiveness of neopterin levels in the early diagnosis of RSA.Methods: Eighty RSA patients and forty-three healthy controls were included in the study. The neopterin concentrations were determined by the enzyme-linked immunosorbent assay (ELISA) method. For the statistical analysis, Mann-Whitney U test and Pearson correlation test were used the; p<0.05 was considered statistically significant.Results: Serum mean neopterin levels were 16.47±0.095 nmol/L in RSA group and 6.14±0.041 nmol/L in control group, respectively. Compared to the control group, a statistically significant increase (p=0.0183) in the serum neopterin levels of the patients was observed. There was a negative correlation between serum neopterin level and age in both the control (R=0.0774, p=0.6236) and RSA groups (R=0.1415, p=0.2089). However, this correlation was not statistically significant (p>0.05).Conclusions: With overstimulation of interferon-γ (INF-γ) during pregnancy, the production of neopterin increases by monocytes/macrophages. The measurement of neopterin levels in the serum contributes to the early diagnosis of pregnancy losses.

The article presents the results of our own studies. The aim was to determine the structural and functional status of blood lymphocytes in patients with acute and prolonged course of infectious mononucleosis (IM) in children. Materials and methods. 102 children were under clinical and laboratory-instrumental supervision, the children were divided into groups: group 1 – 65 children with IM with an acute course of the disease; group 2 – 37 children with a prolonged course of the disease. All children underwent standard clinical laboratory and instrumental laboratory examinations. The diagnosis of IM was confirmed by PCR (detection of EBV DNA in the blood) and ELISA (anti-EBV IgM and IgG). Research results. In the study of the structural state of the cytoplasmic membrane of the lymphocytes in the blood of patients with MI in the onset of the disease, it was found that the average values of penetration rate of the electron paramagnetic resonance of spin probes (PR EPR s. p.) in children of both groups were significantly higher than normal (P < 0.001). There are also differences between groups of patients. In this case, the value of PR EPR s. p. in patients with a prolonged course by 15.8 % exceeded those in patients with acute IM (P < 0.001). According to the rate of microviscosity of the intracellular content (MV IC), its values were reduced compared with the control – by 22.1 % (P < 0.001) in patients with acute course of the disease and by 25.1 % – with a prolonged course of IM). In addition, in patients with a prolonged course of the disease, the values were 9 % lower than in the group with acute infectious mononucleosis. When considering immunological parameters, it was found that the indicators of the T-immune system for patients with a prolonged course of the disease in comparison with the alternative group was characterized by a decrease in the content of CD3 <50 % (respectively in 51.3 % and 26.2 % of patients; P < 0.05); CD4 <31 % (62.1 % and 32.4 %, respectively; P < 0.05) and CD8 <15 % (37.8 % and 10.8 %, respectively; P < 0.01). With regard to the cytokine profile, the level of IL-1 <20.0 pg/ml was determined 3.5 times more often in patients with a prolonged course of the disease compared to the acute course (64.8 % and 18.5 % of patients, respectively); TNFα <20.0 pg/ml 1.9 times more often (48.6 % and 24.6 %, respectively) and a very high (>30.1 pg/ml) level of IL4 in 40.5 % and 20 %). From the B-system of immunity in patients with a prolonged course of IM in comparison with the acute course increased content of CD22 was more often determined, as well as low levels of IgA, IgM <1.1 g/l and IgG <10.0 g/l. Conclusions. According to the results of observations, the pathogenetic role of the violation of the structural organization of blood lymphocytes in the formation of IM is established. It was found that these disorders in the form of increased permeability of their cytoplasmic membrane and reduced viscoelastic properties of their intracellular environment are more pronounced with a prolonged course of the disease, which is a factor in the prolongation of the disease. It is determined that the indicators of cellular and humoral parts of the immune system affect the course of IM. During formation of an acute course of IM in children already in the acute period of a disease activation of both cellular and humoral links of immunity, which is shown in the form of increase in relative content of CD3+, CD4+, CD8+ and CD22+ and levels of immunoglobulins M, A, is noted. For the prolonged course of the disease depression of T-cell immunity in the form of a decrease in the relative content of CD3+, CD4+ and CD8+ lymphocytes and an increase in CD22+, as well as inhibition of antibody genesis are characteristic. It was found that the variant of IM depends on the type of reaction of T-helper clones, namely – in the initial period of manifestation of IM with its acute course there is activation of T1 and T2 helper response, which manifests itself in a significant increase in IL-1, TNFα and moderate IL-4. Prolonged course of the disease is formed against the background of weak activation of pro-inflammatory interleukins (IL-1, TNFα) and significant – anti-inflammatory IL-4.

Abstract Hepatitis B is a life-threatening viral liver infection caused by the hepatitis B virus. Neopterin is regarded as an immunologic biomarker of several diseases related to activation of the cellular immune system. Hepatitis B infection is associated with increased production of cellular immune system markers. We aimed to investigate whether there is a relationship between hepatitis B surface antigen-positivity (HBsAg +) and neopterin to determine the role of neopterin in the early diagnosis of hepatitis B infections. Seventy-two HBsAg (+) patients with normal liver function tests and forty-three controls were included in the study. Neopterin levels were 17.6 ± 0.13 nmol/L in HBsAg (+) patients; and 9.12 ± 0.09 nmol/L in infection-free controls, respectively. Compared to the control group, a statistically significant increase (p < 0.001) in the serum neopterin levels of the patients was observed. No significant relationship was determined between neopterin levels and age/sex (both, p > 0.05). With overstimulation of interferon-gamma, the production of neopterin increases by monocytes/macrophages. Likewise with other diseases associated with an activated cellular immune system, this study shows that neopterin can be a predictive biomarker for persistent carriers of hepatitis B infection.

Acute Infectious Mononucleosis

Objective. To analyze clinical and laboratory parameters, as well as the dynamics of cytokine production in children of different ages with acute infectious mononucleosis caused by Epstein-Barr virus (EBV mononucleosis). Patients and methods. We examined two groups of patients: group I included 20 children aged 1 to 7 years, whereas group II included 29 children aged 8 to 17 years. All study participants were tested in the acute phase of the disease and in early convalescence. We evaluated serum levels of interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), and interferon-α (IFN-α) using enzyme-linked immunosorbent assay (ELISA) (standard Vektor-Best kits, Russia). Data analysis was performed using Microsoft Excel 2019 for Windows and IBM SPSS statistics; we applied the methods of non-parametric statistics. Differences were considered significant at p < 0.05. Results. The majority of children had fever, intoxication, acute tonsillitis, and enlarged cervical lymph nodes. Laboratory makers, such as lymphocytosis, neutropenia, and thrombocytopenia were more pronounced in children from group II. In both groups, the level of cytokines in the acute period of the disease was higher than the discriminatory one. In early convalescence, patients from group I demonstrated more significant reduction in the cytokine level than patients from group II (р < 0.05). In children over 7 years of age, the levels of IL-10 and TNF-α positively correlated with the disease duration (p < 0.01 and p < 0.05, respectively) Conclusion. The level of cytokine production in acute EBV mononucleosis depends on patients’ age. Concentrations of IL-10 and TNF-α can serve as markers reflecting the severity of EBV mononucleosis and can be used for disease prognosis.

Cytokine Profiles

Immunosensitization to metal ions through occupational and environmental exposure has been described in earlier papers from this project. Here we discuss the possible role of cytokine profiling in demonstrating and understanding this phenomenon. The cytokines are a large family of polypeptides exerting autocrine, paracrine, and/or endocrine effects. They include interleukins (ILs), interferons (IFNs), and growth factors. They may be grouped as pro-inflammatory (e.g., IL-1, IL-6, IL-12, IL-18, TNF-α), anti-inflammatory (e.g., IL-10), or those regulating T-helper (TH) cell function. The latter are subdivided into those associated with TH1 (e.g., IL-2, IL-12, IFN-γ, TNF-β) or TH2 (e.g., IL-4, IL-5, IL-13) cell function. Because different types of immune reactions (e.g., immediate reaction vs. delayed-type hypersensitivity) differentially involve TH1 and TH2 cells, measurement of cytokine production in response to metal ions can potentially give insight into underlying immune mechanisms and responses. Examples are given for species of Ni, Cr, Co, Hg, Cd, and Be; and in less detail for species of Fe, Pt, Pd, and Rh. Antibodies are available commercially that allow for the determination of many cytokines, and such measurements are most usefully performed with body fluids, supernatants from stimulated lymphocyte cultures, or lysates of lymphocytes or other biopsied cells. The predominant methods include enzyme-linked immunosorbent assay (ELISA) and flow cytometric measurement of the cytokine, bioassay of its activity in cell culture, and polymerase chain reaction (PCR) assessment of its mRNA level. In practice, levels of individual cytokines are highly variable between individuals, and reliable reference values are generally lacking. Ratios of cytokines are more informative than absolute concentrations, and biological variability in cytokine production dictates that repeated testing is necessary to confirm trends. Determining cytokine profiles is presently of questionable diagnostic utility in individual cases of metal sensitization, but is providing mechanistic insights in a research context.

The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects millions of people and killed hundred-thousands of individuals. While acute and intermediate interactions between SARS-CoV-2 and the immune system have been studied extensively, long-term impacts on the cellular immune system remained to be analyzed. Here, we comprehensively characterized immunological changes in peripheral blood mononuclear cells in 49 COVID-19 convalescent individuals (CI) in comparison to 27 matched SARS-CoV-2 unexposed individuals (UI). Despite recovery from the disease for more than 2 months, CI showed significant decreases in frequencies of invariant NKT and NKT-like cells compared to UI. Concomitant with the decrease in NKT-like cells, an increase in the percentage of Annexin V and 7-AAD double positive NKT-like cells was detected, suggesting that the reduction in NKT-like cells results from cell death months after recovery. Significant increases in regulatory T cell frequencies, TIM-3 expression on CD4 and CD8 T cells, as well as PD-L1 expression on B cells were also observed in CI, while the cytotoxic potential of T cells and NKT-like cells, defined by GzmB expression, was significantly diminished. However, both CD4 and CD8 T cells of CI showed increased Ki67 expression and were fully capable to proliferate and produce effector cytokines upon TCR stimulation. Collectively, we provide the first comprehensive characterization of immune signatures in patients recovering from SARS-CoV-2 infection, suggesting that the cellular immune system of COVID-19 patients is still under a sustained influence even months after the recovery from disease.
