Abstract
The number of people suffering from allergies is increasing worldwide every year. With the prevalence of domestic animals, especially dogs, allergens associated with them can be found ubiquitously, thereby increasing the risk of anaphylaxis in sensitized individuals. Currently, there are 8 known dog allergens, but not all of them have been thoroughly studied. The commonly used skin prick tests often fall short and fail to provide a comprehensive assessment of a patient's condition, thus making allergy diagnosis challenging. Fortunately, the introduction of new allergy diagnostic methods has made it possible to accurately identify clinically significant allergens for patients. These findings can then be used to prescribe appropriate therapy or provide specific recommendations to the patients. This review focuses on the most important dog allergens and modern allergy diagnostic techniques that are gradually being incorporated into medical practice, thus expanding the capabilities of allergists.

Experimental Research Models to Assess the Cross-Reactivity between Can f 5 and Human PSA—Two Different Perspectives. Int J Mol Sci 2022; 23:ijms231911223. [PMID: 36232522 PMCID: PMC9570149 DOI: 10.3390/ijms231911223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 09/19/2022] [Accepted: 09/20/2022] [Indexed: 11/17/2022] Open
Abstract
The similarity in antigenic structures, including the degree of correspondence between the amino acid sequence and the spatial structure, is not always reflected in the actual cross-reactivity of allergens. Inhibition tests appear to be an invaluable tool for assessing potential cross-reactivity between allergens under natural conditions. In this publication, we present two experimental models of inhibition tests: solid phase (SP-IT) and liquid phase (LP-IT). As an exemplary research model, we used the cross-reactivity between human PSA and anti-Can f 5 IgE antibodies. We performed an SP-IT model using a microplate coated with human PSA. The LP-IT model was based on mixing anti-Can f 5 IgE positive serum with a material containing human PSA. Anti-Can f 5 IgE and PSA concentrations before and after inhibition were measured to evaluate inhibition effectiveness. The results of the performed experiments showed that both proposed models of inhibition tests are an effective tools for studying cross-reactive relationships between antigens. In the SP-IT, the concentration of anti-Can f 5 decreased by 21.6% and, in the LP-IT, it decreased by 34.51%. In turn, the PSA concentration in the SP-IT decreased by 11.25% and, in the LP-IT, it decreased by 15.49%. In conclusion, both the SP-IT and the LP-IT seem to be effective tools for assessing the actual cross-reactivity between different allergens.

Abstract
Objective Cytokines and enzymes in follicular fluid (FF) may have a crucial role in fertility. This study aimed to analyse the results of in vitro fertilization/embryo transfer (IVF/ET) and compare them with matrix metalloproteinase 9 (MMP-9) and cytokine concentrations in FF. Methods This case–control study included 20 randomly selected patients with a positive pregnancy (PPG) test and 20 with a negative pregnancy (NPG) test after IVF/ET. In FF obtained during oocyte retrieval, the concentrations of soluble forms of MMP-9, interleukin 1 (IL-1) alpha, IL-1 beta, interferon gamma, IL-2, IL-4, IL-6, IL-8, and IL-10 were measured. Their effect on the characteristics of follicles, embryos, and the efficiency of IVF and ET were analysed. Results High-sensitivity IL-4 concentrations were significantly higher in patients with a PPG test than in those with an NPG test (3.15 ± 3.23 vs 1.91 ± 0.35 pg/mL). The number of top-quality embryos achieved was significantly higher in patients with a PPG test than in those with an NPG test (2.6 ± 1.39 vs 1.75 ± 1.21), and they were negatively correlated with IL-8 concentrations in FF. Conclusion Further research on the role of IL-4 and IL-8 in FF is required to establish any clinical benefit of determining their concentrations in FF of infertile women.

Abstract
Introduction: Progesterone is essential for both the initiation and the maintenance of pregnancy. The immunological effects of progesterone are mediated by the progesterone-induced blocking factor (PIBF), which is an immunomodulatory factor with anti-abortive properties. The aim of the research was to establish the cytokine profile and PIBF1 concentration in follicular fluid (FF) of patients undergoing in vitro fertilization (IVF). Methods: Seventy-eight patients who qualified for IVF underwent a detailed medical interview, including the course of fertility treatment and physical, gynecological, and cytological examinations. The concentration of PIBF1, IL-18, IL-2, IL-4, IL-6, IL-10, interferon-γ (IFN-γ), IL-1α, IL-1β, IL-5, IL-8, and IL-15 in FF during ovarian puncture was measured using commercially available ELISA kits. Results: IL-1 beta concentration was lower in the FF of patients with successful IVF. IL-8 concentration in FF correlated with the number of cumulus-oocyte complexes (COC-1), metaphase II (MII), and top-quality embryos. PIBF1 concentration had a positive correlation with the number of MII and top-quality embryos. IL-2 and IL-6 concentrations were positively correlated with the number of COC-1 and MII. An important parameter in assessing the chances of successful IVF is the number of top-quality embryos achieved. Conclusion: Higher PIBF1 concentration in FF may indicate a greater possibility of successful IVF due to the higher number of top-quality embryos. IL-1 beta concentration was found to be lower in the FF of patients with successful IVF. Therefore, PIBF1 and IL-1 beta in FF could be candidates for a marker of successful IVF.

J Asthma Allergy 2021; 14:1231-1242. [PMID: 34707374 PMCID: PMC8544268 DOI: 10.2147/jaa.s334195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Accepted: 10/04/2021] [Indexed: 11/28/2022] Open
Abstract
Background The prevalence of allergies has increased significantly in the past decade. Further research on allergic diseases caused by furry animals is of great importance for the clinical prevention, diagnosis and treatment of allergies. Objective To identify the sensitization profile and clinical association of various furry animal crude extracts and components based on component resolved diagnosis (CRD). Methods A total of 211 patients with allergic rhinitis with sensitivities to cats and/or dogs were recruited, and the specific immunoglobulin E (sIgE) against various furry animals (such as dog/cat extracts and their components, pigeon, parrot, duck, chicken, sheep, rat, mouse, goose, cow and horse extracts) were measured to analyze the sensitization profiles, cross-reactivity and clinical relevance with regards to allergies. Results A total of 91.67% of cat-sensitized patients were sensitive to Fel d 1, while only 16.03% of cat-sensitized patients responded to Fel d 2. Can f 1 and Can f 5 were the major components of dogs, and the positive rates were 23.53% and 16.18%, respectively. Twenty percent of patients were sensitized to 10 other furry animals, and the positive rate was between 0% and 19.12%. There was a significant correlation between components (Can f 1–5 and Fel d 2) and 5 furry animals (mouse, sheep, Horse, rat, cow), especially between serum albumin (SA) (Can f 3, Fel d 2) and furry animals. Most of the animal crude extracts and components sensitization rates in patients who were SA-positive were significantly higher than that of patients who were SA-negative. In particular, for sensitization to mice, sheep, horses, rats and cows, more than 10-fold higher in patients who were SA-positive than in patients who were SA-negative. The VAS of symptoms and life of quality (LoQ) in the SA-sensitized patients was higher than that in unsensitized patients, and the patients with lipocalin sensitivities had a worse LoQ. Conclusion Serum albumin Fel d 2 and Can f 3, as minor allergens in cats and dogs, but not lipocalin or prostatic kallikrein, is associated with other furry animals presumably due to serum albumin cross-reactivity. Patients sensitized with serum albumin had a significantly higher risk of sensitization to other animals and had a higher rhinitis VAS score.
