The Relationship

The article presents a comparative analysis of the cytokine network in 161 patients with pertussis under the age of 1 year and in 180 patients over the age of 1 year. The studies revealed lower production of immunoregulatory cytokines (interferon-γ and interleukin-2) in patients under the age of 1 year at all stages of the disease and with all variants of pertussis (both mono- and mixed infections). The researchers revealed the relationship between the level of interferon-γ production and the severity of pertussis. They revealed age differences in the interferon-8 production in patients with mixed infection, which can determine clinical features and cause bronchopulmonary complications. The authors demonstrated the features of the dynamics of spontaneous and induced production of interleukin-6 and anti-inflammatory cytokines (interleukin-4, interleukin-10) in children under the age of 1 year; these features can be considered as immunological markers determining the imperfection of the humoral response in patients with pertussis in this age group.

Background Analysis of recent research indicated that T-helper cells may play an important role in the pathogenesis of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Objective The purpose of this study was to investigate the peripheral blood Th1 and Th2 cells and eosinophil population in patients with CRS. Methods Peripheral blood samples were obtained from nine nonatopic controls, 37 patients with CRSsNP, and 66 patients with CRSwNP. The samples were then analyzed by flow cytometry analysis (Th1 cell [CD4+, interleukin 4−, interferon γ+]; and Th2 cell [CD4+, interleukin 4+, interferon γ−]). The patients were stratified into four groups based on their allergic status by using skin-prick test results and immunoglobulin E level measurements as the following: (1) nonatopic CRSsNP, (2) nonatopic CRSwNP, (3) atopic CRSsNP, and (4) atopic CRSwNP. Eosinophil counts were also compared. The severity of nasal diseases in these patients was assessed via the Lund-Mackay score. Results No significant differences in peripheral blood Th1 and Th2 cells were found among all the atopic, nonatopic CRS groups, and the nonatopic control groups. Peripheral blood eosinophil levels in atopic CRSwNP were significantly elevated compared with the nonatopic controls (p < 0.05), but no significant difference was found among all atopic and nonatopic CRS groups. Conclusion Analysis of our data demonstrated that a proportion of systemic Th1- and Th2-skewed lymphocytes in all CRS groups were similar to that in healthy subjects, irrespective of atopic status. The patients with CRSwNP and with atopy but not the patients with CRSsNP and with atopy demonstrated systemic eosinophilic inflammation. Further studies are needed to investigate underlying pathophysiologic mechanism or endotypes.

Background: Erythema nodosum leprosum (ENL) is a frequent complication of multibacillary leprosy that can result in significant morbidity, including peripheral nerve damage and physical disability. The identification of possible serum markers could be a valuable tool for the early detection of ENL. Aims: The purpose of this study was to evaluate selected serum mediators involved in the innate and adaptive immune responses to identify possible immunomarkers for ENL. Methods: The levels of interleukin-2, interleukin-4, interleukin-6, interleukin-10, interleukin-17, interferon-γ, tumor necrosis factor, nitric oxide and anti-phenolic glycolipid-I antibodies were measured in the sera of leprosy patients with ENL [at the beginning of reaction (M0) and 1 month later (M1)], and then compared with the levels of the same markers in patients with untreated multibacillary leprosy without ENL (controls with leprosy: CTRL) and healthy individuals (healthy controls: CTRH). Results: Significantly higher levels of serum interleukin-6 were observed in M0 than in CTRL. In addition, pairwise comparisons showed higher levels of interleukin-6 in M0 compared to M1. Levels of tumor necrosis factor were higher in M0 than in CTRL, with no significant difference between M0 and M1. There were no differences in the levels of interleukin-2, interleukin-4, interleukin-10, interleukin-17 or interferon-γ between groups. The CTRL group had higher levels of nitric oxide compared to M0 and M1. High levels of anti-phenolic glycolipid-I were observed in M0, M1 and CTRL than in CTRH. Limitations: Three patients were not assessed at M1, decreasing the number of evaluated patients from 14 to 11. Conclusion: High-serum levels of interleukin-6 were observed during ENL, primarily in patients with more severe reactions; levels decreased after specific therapy, suggesting a role for this cytokine in pathogenesis and its utility as an ENL biomarker. Further studies should explore whether interleukin-6 could also be used as a predictive marker for ENL or as a specific target for its treatment.

Aim. To study the levels of pro- and anti-inflammatory cytokines in cervical secretion in females with cervical epithelial dysplasia and latent papillomavirus infection. Methods. The study included 120 females aged 20 to 40 years with cervical papillomavirus infection, who were assigned to two groups using «case-control» method. The first group included 60 females with latent disease, the second group - 60 females with mild and moderate cervical epithelial dysplasia (cervical intraepithelial neoplasia stages I and II). Cytokine levels in cervical secretion were measured by ELISA using «ProCon» test system. Results. ELISA test showed increased levels of interleukin-4 and interleukin-10 (43 [21; 74] and 48 [12; 88] pg/ml, respectively) and decreased levels of interleukin-2 (18.5 [5.5; 27.5] pg/ml), interleukin-6 (0.6 [0.06; 0.9] pg/ml), tumor necrosis factor alpha (88.5 [0; 123] pg/ml), interferon γ (2 [0; 4] pg/ml) in cervical secretion of females with cervical epithelial dysplasia compared to females with latent papillomavirus infection. Thus, females with cervical epithelial dysplasia showed increased levels of anti-inflammatory cytokines: interleukin-4 - by 2.7 times and interleukin-10 - by 2.4 times compared to females with latent disease, while levels of pro-inflammatory cytokines was decreased as following: interleukin-2 - by 1.4 times, interleukin-6 - by 4.5 times, tumor necrosis factor alpha - by 1.8 times, interferon γ - by 6.3 times (p 0.05). Conclusion. Imbalance of immune response cytokine regulation with anti-inflammatory cytokines prevailing might be an important factor facilitating persistence of papillomavirus in cervical epithelium and contributing to cervical epithelial dysplasia onset and progression.

Abstract The flow cytometric analysis of DNA content in cells obtained from a case of Lennert's lymphoma demonstrated the presence of a discrete hypotetraploid cell population. Correlated multiparameter analysis of DNA, light scatter, and surface antigens by flow cytometry showed that the hypotetraploid cells were intermediate to large cells expressing T11, T3, and T4 antigens and lacking B1 and T8 antigens. These findings suggest that Lennert's lymphoma represents a malignant neoplasm of T- helper lymphocytes.
