Sex steroid hormones and allergic diseases in children: a pilot birth cohort study in the Japan Environment and Children's Study cohort. BMC Pediatr 2023; 23:479. [PMID: 37735641 PMCID: PMC10512488 DOI: 10.1186/s12887-023-04302-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 09/09/2023] [Indexed: 09/23/2023] Open
Abstract
BACKGROUND Numerous studies suggest that sex steroids might play a role in sex disparity observed in allergic diseases in adults. However, whether sex hormones influence allergic diseases in children remains unclear. The aim of the present study was to examine the association of sex steroid hormones with allergic disease in Japanese children. METHODS The present cross-sectional study included 145 6-year-old children participating in a pilot birth cohort study in the Japan Environment and Children's Study. Data on allergic diseases were obtained from questionnaires, and serum levels of sex steroid hormones and allergen-specific IgE were measured. Logistic regression was performed to evaluate the association of sex hormones with allergic diseases. RESULTS After adjusted sex, amount of body fat at 6 years, parental history of allergic disease, and exposure to tobacco smoke, serum dehydroepiandrosterone sulfate level was significantly associated with reduced odds of any allergic disease (adjusted odds ratio, 0.58; 95% confidence interval, 0.36-0.93; P = 0.024) and serum follicle-stimulating hormone level was significantly associated with increased odds of any allergic disease (adjusted odds ratio, 2.04; 95% confidence interval, 1.01-4.11, P = 0.046). Dehydroepiandrosterone sulfate level showed a significant association with number of allergic diseases. CONCLUSIONS The current study findings suggest that sex hormones may play an important role in the development of allergic diseases in prepubertal children.

Intrinsic Effects of Exposome in Atopic Dermatitis: Genomics, Epigenomics and Regulatory Layers. J Clin Med 2023; 12:4000.

Abstract
Atopic dermatitis (AD) or atopic eczema is an increasingly manifested inflammatory skin disorder of complex etiology which is modulated by both extrinsic and intrinsic factors. The exposome includes a person's lifetime exposures and their effects. We recently reviewed the extrinsic exposome's environmental risk factors that contribute to AD. The periods of pregnancy, infancy, and teenage years are recognized as crucial stages in the formation of AD, where the exposome leads to enduring impacts on the immune system. However, research is now focusing on the interactions between intrinsic pathways that are modulated by the extrinsic exposome, including genetic variation, epigenetic modifications, and signals, such as diet, stress, and microbiome interactions. As a result, immune dysregulation, barrier dysfunction, hormonal fluctuations, and skin microbiome dysbiosis are important factors contributing to AD development, and their in-depth understanding is crucial not only for AD treatment but also for similar inflammatory disorders.

Abstract
Background: It has been suggested that cortisol levels are abnormal in chronic urticaria and atopic dermatitis, but other steroids, such as dehydroepiandrosterone (DHEA) and testosterone, are still unknown, and whether these hormones affect the maintenance of skin homeostasis or the pathogenesis of skin diseases is not fully understood. Limited data are available on steroid levels in prurigo nodularis (PN)-related research, and no study has examined the association between pruritus severity and steroid levels in PN patients. Aims: This pilot study aimed to investigate the differences in the levels of five steroids combined with their ratios in plasma between PN patients and controls and to examine the associations between the biomarkers and pruritus severity. Methods: Plasma concentrations of five steroids, including cortisol, cortisone, testosterone, progesterone, and dehydroepiandrosterone (DHEA), in 36 patients with PN were compared with concentrations in thirty-six and matched healthy controls. The concentrations of steroids were quantitated using liquid chromatography-tandem mass spectrometry. The PN symptoms, including pruritus severity, pain, and life quality, were assessed with the use of the visual analog scale, prurigo score index, numerical rating scale, and verbal rating scale and dermatology life quality index scores. Results: In comparison with controls, PN patients had lower levels of plasma cortisol and cortisone, which negatively correlated with PN symptoms. PN patients had higher levels of cortisone and testosterone to cortisol, which positively correlated with pruritus severity. Additionally, there were no significant differences in plasma concentrations of DHEA and testosterone between the two groups. We found no correlation between plasma concentrations of DHEA and testosterone and pruritus severity. Conclusion: This pilot study suggests that there may be abnormalities in peripheral blood levels of cortisol, and cortisone and the ratios of cortisone and testosterone to cortisol in patients with PN, and they are related to pruritus severity. The plasma concentrations of testosterone and DHEA may be not abnormal in PN patients and may not be associated with pruritus severity.

Abstract
Coronavirus disease 2019 (COVID-19), a pandemic disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, can affect almost all systems and organs of the human body, including those responsible for reproductive function in women. The multisystem inflammatory response in COVID-19 shows many analogies with mast cell activation syndrome (MCAS), and MCAS may be an important component in the course of COVID-19. Of note, the female sex hormones estradiol (E2) and progesterone (P4) significantly influence mast cell (MC) behavior. This review presents the importance of MCs and the mediators from their granules in the female reproductive system, including pregnancy, and discusses the mechanism of potential disorders related to MCAS. Then, the available data on COVID-19 in the context of hormonal disorders, the course of endometriosis, female fertility, and the course of pregnancy were compiled to verify intuitively predicted threats. Surprisingly, although COVID-19 hyperinflammation and post-COVID-19 illness may be rooted in MCAS, the available clinical data do not provide grounds for treating this mechanism as significantly increasing the risk of abnormal female reproductive function, including pregnancy. Further studies in the context of post COVID-19 condition (long COVID), where inflammation and a procoagulative state resemble many aspects of MCAS, are needed.

Dermatology 2020; 236:336-344. [PMID: 31914445 DOI: 10.1159/000504388] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Accepted: 10/25/2019] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Depression is a common comorbid condition with atopic dermatitis (AD), particularly during the active disease cycle. Controversial results regarding the contribution of biological sex, immunoglobulin E (IgE) sensitization, and cortisol on AD severity and comorbid depression justify further investigation. OBJECTIVE AND METHODS To explore the influence of sex and IgE sensitization on biochemical and psychological parameters, and severity of AD, a case-control study of 105 volunteers (56 AD, 49 healthy controls (HC); 50 males, 55 females) was conducted over 10 weeks, starting at dermatological symptom onset. Disease severity, serum IgE, cortisol and testosterone levels, and depression scores were assessed at study baseline and after 10 weeks of conventional treatment. RESULTS Dermatological severity differed among AD males by IgE sensitization and was elevated in males with extrinsic atopic dermatitis (EAD). Hamilton Depression Rating Scale (HAMD) scores were elevated in all patients at study baseline and improved with symptom reduction to HC levels, except female EAD. Severity of depression and dermatitis were correlated in EAD males at baseline and at week 10. Serum cortisol was elevated in male EAD at baseline, in contrast to males with intrinsic atopic dermatitis (IAD) at week 10. In addition, cortisol levels were found negatively correlated with SCORAD and HAMD scores in EAD males at week 10. CONCLUSION Pathophysiological features of AD and depression are likely related to different inflammation-based effects and appear to be biological sex-dependent. Cortisol levels depend on biological sex and IgE sensitization in AD and increase in males with EAD at exacerbation and IAD males at resolution. Biological sex-related disease triggers, IgE sensitization, and cortisol levels are important for the understanding of the mechanisms underlying AD and comorbid depression.

Abstract
Dehydroepiandrosterone (DHEA) is a steroidal hormone secreted by Zonareticularis of the adrenal cortex with a characteristic age related pattern of secretion. These hormones are inactive precursors that are transformed into active sex steroids in peripheral target tissues. These hormones are used for the energy, vitality and the natural support of most bodily functions that involve the endocrine system. DHEA is a 19 carbon steroid hormone, is lipophilic, and can be converted to DHEAs by activity of the enzyme sulphotransferasein the liver and adrenal glands. These are naturally synthesized in our body through cholesterol- pregnenolone pathway and can also be synthesized from various other sources like diosgenin, geniestein, wild yam, soy and cholesterol in laboratory. It serves as an indirect precursor to estrogen and testosterone and other steroid hormones. This hormone progressively declines at the rate of 2% per year. DHEA evidence a large variety of pharmacological activities like antidiabetic, anticancer, anti-allergic, obesity treatment and cardiovascular property. It is beneficial in autoimmune disorders like lupus erythematosus, immune modulation, muscle building and hormonal problems. DHEA is known as an anti-ageing hormone, in osteoporosis and in dementia. It can also be used as a supplement as directed by the physician in various condition.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by T helper 2 cell (Th2)-shifted abnormal immunity, skin barrier impairment, and pruritus. The prevalence of AD in childhood is slightly higher in boys than in girls; after puberty, the sexual difference is reversed. The female preponderance in all generations exists in intrinsic AD with enhanced Th1 activity and nickel allergy, lacking increased serum IgE or filaggrin mutation. AD is often deteriorated before menstruation. We review the effects of sex hormones on immune responses and skin permeability barrier and propose possible hypotheses for the above phenomena. After puberty, the immune responses of patients are remarkably influenced by sex hormones. Estrogen and progesterone enhance the activities of Th2/regulatory T cell (Treg) but suppress Th1/Th17. Androgens suppress Th1/Th2/Th17 and induce Treg. The skin permeability barrier is fortified by estrogen but is impaired by progesterone and androgens. Dehydroepiandrosterone suppresses Th2 but enhances Th1. The amount of steroid sulfatase converting dehydroepiandrosterone sulfate to dehydroepiandrosterone is higher in women than in men, and thus, women might be more susceptible to the influence of dehydroepiandrosterone. The balance of modulatory effects of sex hormones on immune responses and skin barrier might regulate the course of AD.

Abstract
Glucocorticoid (GC) therapy is one of the methods of choices for treatment of autoimmune diseases (ADs). In addition, adrenal androgens are known as immunoprotective GC-antagonists. Adrenal steroids preferentially influence the Th1-components over the Th2 ones. We investigated steroid metabolome (using gas chromatography-mass spectrometry) in healthy controls (H), GC-untreated patients with ADs different from IgA nephropathy (U), GC-treated patients with ADs different from IgA nephropathy (T) and in patients with IgA nephropathy (IgAN), which were monitored on the beginning (N0), after one week (N1) and after one month (N2) of prednisolone therapy (60 mg of prednisolone/day/m2 of body surface). Between-group differences were assessed by one-way ANOVA, while the changes during the therapy were evaluated by repeated measures ANOVA. The ANOVA testing was followed by Duncan’s multiple comparisons. IgAN patients and patients with other ADs exhibited lack of adrenal androgens due to attenuated activity of adrenal zona reticularis (ZR). Androgen levels including their 7α-, 7β-, and 16α-hydroxy-metabolites were further restrained by GC-therapy. Based on these results and data from the literature, we addressed the question, whether a combination of GCs with Δ5-steroids or their more stable synthetic derivatives may be optimal for the treatment of antibodies-mediated ADs.

Abstract
Chronic urticaria is a challenging problem since the exact cause and mechanism involved in the disease development have still remained unknown. This disease is associated with mast cells activation and immunoinflammatory processes. Interestingly, dysfunctions of the neuroendocrine-immune system due to stress and other factors seem to appear as a very interesting theory for urticaria pathogenesis. Dehydroepiandrosterone and its sulfate derivative (DHEA-S) appear to have regulatory effects in immune homeostasis and are regulated by the nervous system, and it is suggested that they may be an integral element of neuroimmunomodulation. Our studies showed substantially decreased serum concentration of DHEA-S in patients with chronic urticaria. However, current knowledge prevents answering whether lower circulating DHEA-S concentration is a primary phenomenon or just an accompanying one which appears as a response of different systems to the course of the illness and may not be of any importance for the pathogenesis of urticaria whatsoever. This review is a summary of clinical research on the role of DHEA in chronic urticaria.

Abstract
Dehydroepiandrosterone (DHEA) is considered as an important immunomodulating and anti-inflammatory hormone. Despite the continuing interest in DHEA replacement therapy, our knowledge of its effects upon asthma is very limited. DHEA is able to reverse cytokine imbalances associated with asthma, may prevent and attenuate allergic inflammation in airways, and does not possess the undesirable side effects of glucocorticoids; therefore, it may be potentially applied in the treatment of asthma. The steroid-sparing effect observed with DHEA clinically could appear especially favorable in asthmatic patients receiving oral treatment and those inhaling high doses of glucocorticoids. In addition, DHEA and its analogs might prove useful in reversing relative glucocorticoids insensitivity in patients with corticosteroid-resistant asthma. In this review we have focused specifically on DHEA's role in asthma.

Abstract
PURPOSE OF REVIEW This review discusses some of the recent advances in basic and clinical research focused on chronic urticaria. It is a concise summary of issues that occupied researchers' attention in the previous year, and it discusses a selection of novel findings that further our understanding of the pathomechanism of this disease. RECENT FINDINGS Particular consideration is given to the role of basophils, the coagulation cascade, fibrinolysis, and hormonal pathways in chronic urticaria pathogenesis. The description of clinical data is focused on prognostic issues, disease severity, and the effects of the disease on patients' quality of life. SUMMARY Mast cells are the key elements in chronic urticaria pathogenesis, whereas basophils should be regarded as bystanders and serve as biomarkers in some chronic urticaria subsets. The coagulation cascade, hormonal factors, and the psychological status of the patients seem to contribute substantially to the course and activity of the disease. Nonsedating second-generation antihistamines should be considered as first-line symptomatic treatment for chronic urticaria. Of note, the dosage should be increased up to four-fold if required before switching to second-line therapies.
