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.

Malaria has been reported as a condition caused by infestation with Plasmodium parasite specie, which is a great public health problem globally, particularly in developing countries like Nigeria. This study was carried out in Federal Medical Centre Umuahia in Abia State, Nigeria. The study was done to determine the maternal serum levels of alpha tumour necrosis factor, interleukin 10, interleukin 6, and interleukin 4 in malaria-infected pregnant women based on parities in Southeast, Nigeria.  A total of 150 subjects between the ages of 18-45 years were recruited for the study comprising 50 subjects each of 3 parities (groups A-C). A commercial ELISA Kit was used to measure all the cytokines. Neither statistically significant differences were found for TNF-α (p=0.636), IL-10 (p=0.892), IL-6 (p=0.306) and IL-4 (p=0.222) between prime parity and second parity nor for TNF-α (p=0.356), IL-10 (p=0.896), IL-6 (p=0.304) and IL-4 (p=0.298) between prime parity and multi-parity of malaria-infected pregnant women. TNF-α (p=0.255), IL-10 (p=0.524), IL-6 (p=0.616), and IL-4 (p=0.672) between second parity and on multi-parity respectively. The study showed no changes in the cytokines studied among the malaria-infected pregnant women based on parities. It shows that the number of pregnancies in women infected with malaria has no changes in the levels of the cytokines studied.

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.

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.

The aim of the present study was to determine the effect of zearalenone (ZEN), administered per os to gilts at doses equivalent to 50%, 100%, and 150% of no-observed-adverse-effect level (NOAEL) values for 14, 28, and 42 days during weaning, on changes in the parameters of the oxidoreductive balance, cytokine secretion, and basal metabolism in ileal Payer’s patches. Immunoenzymatic ELISA tests and biochemical methods were used to measure the concentrations of interleukin 1α, interleukin 1β, interleukin 12/23p40, interleukin 2, interferon γ, interleukin 4, interleukin 6, interleukin 8, tumor necrosis factor α, interleukin 10, transforming growth factor β, malondialdehyde, sulfhydryl groups, fructose, glucose, and proline, as well as the activity of peroxidase, superoxide dismutase and catalase. The study demonstrated that ZEN doses corresponding to 50%, 100%, and 150% of NOAEL values, i.e., 5 µg, 10 µg, and 15 µg ZEN/kg BW, respectively, have proinflammatory properties, exacerbate oxidative stress responses, and disrupt basal metabolism in ileal Payer’s patches in gilts.
