Does stress response axis activation differ between patients with autoimmune disease and healthy people?

Many studies have shown that patients with autoimmune disease present a hypoactive hypothalamic-pituitary-adrenal (HPA) axis, but the results are controversial. Our objective was to study differences in stress response axis activity between patients with autoimmune disease and healthy people. The study sample consisted of 97 women divided into four groups: 37 healthy women (HW), 21 with systemic lupus erythematosus (SLE), 21 with Sjögren's syndrome (SS), and 18 with systemic sclerosis (SSc). After being exposed to a stress task, participants' skin conductance and salivary cortisol levels were measured in order to assess their response to psychological stress. Diurnal cortisol concentrations were assessed by measuring salivary cortisol in samples collected five times over one day. In addition, self-administered questionnaires were used to assess psychological variables. A time × group interaction effect was found (p = 0.003) in salivary cortisol secretion in response to stressful challenge. The healthy group presented normal activation, the SS and SLE groups showed no activation, and the SSc group presented a similar activation pattern to the HW group, except at the time of recovery. Total cortisol production (AUCg) was higher in the SSc group than in the HW group (p = 0.001). Differences were also observed in the cortisol AUCg collected over one day between healthy women and patients with SLE (p = 0.004) as well as with SSc (p = 0.001): women with SLE and SSc presented higher total hormone production than healthy women. Patients with autoimmune disease present a different HPA axis response, which may contribute to the harmful effects of stress in these diseases.

Psychological and quality of life effects of vaccination against COVID-19 in patients with systemic autoimmune diseases.

To verify the psychological and quality of life benefits of vaccination against COVID-19 in patients with systemic autoimmune diseases. In this study, levels of psychological stress, psychopathological symptoms, quality of life, and satisfaction with life were compared in patients with systemic autoimmune diseases vaccinated against COVID-19 (n = 132) versus unvaccinated patients (n = 254). To this end, we used the Perceived Stress Scale (PSS), Symptom Checklist-90-Revised (SCL-90-R), EUROQoL-5Q health questionnaire, and Satisfaction with Life Scale (SWLS), respectively. Statistically significant differences were found with better scores in the vaccinated group in the following quality of life dimensions: mobility (p ≤ 0.010), domestic activities (p ≤ 0.004), pain/discomfort (p ≤ 0.001), and anxiety/depression (p≤ 0.005). The scores were also significantly higher in the vaccinated group for the total values of quality of life (p ≤ 0.001), health status self-assessment on the EUROQoL-5Q (p ≤ 0.043), and satisfaction with life (p ≤ 0.015). In addition, the unvaccinated group presented higher scores with clinically pathological levels in depression and psychoticism for somatizations (p ≤ 0.006), depression (p ≤ 0.015), anxiety (p ≤ 0.003), and phobic anxiety (p ≤ 0.001). Finally, participants vaccinated with the complete regimen showed better levels of psychological well-being than those who were not vaccinated or those that had not completed the vaccination regimen. Our results reflect and confirm the positive effects reported elsewhere of the COVID-19 vaccine in autoimmune patients with systemic diseases, both in terms of quality and satisfaction with life as well as psychopathological symptoms and perceived stress. These benefits increased as the patients completed their vaccination schedule.

Hair cortisol concentrations in a Spanish sample of healthy adults.

BACKGROUND: Hair cortisol concentration (HCC), as a novel promising method to retrospectively measure hypothalamic-pituitary-adrenal (HPA) axis activation, is being increasingly studied. We tested the relationships between HCC and a range of possible confounding variables in a Spanish sample of healthy adults and pregnant women. METHODS: The number of healthy adults who participated in the study was 529, being 270 males and 259 females, with a combined mean age of 37.88 years (SD = 15.66). Additionally, a separate sample of 62 pregnant women was also recruited with a mean age of 32.95 (SD = 3.67), and in the first trimester of pregnancy. Each participant was interviewed before the study to obtain sociodemographic and lifestyle variables, and a hair sample was taken from the posterior vertex of the head, cut as close to the scalp as possible. Assuming the average growth rate of head hair is 1 cm per month, a 3-cm segment was analysed, in order to measure the cortisol concentrations from a three-month period. For the pregnant women, hair samples for each trimester of pregnancy were analysed. RESULTS: The mean hair cortisol concentration was 127.91 (111.52) pg/mg for the general sample. The variables of age, education, employment status, use of hair dyes, use of oral contraceptives, and physical exercise had a significant relation to HCC. When adjusted for further variables, only education and physical exercise remained statistically significant. When including the use of oral contraceptives and only with respect to females, only physical exercise remains statistically significant. For the subsample of pregnant woman, the mean hair cortisol concentration was 334.51 (409.77) pg/mg for the first trimester, 302.18 (270.24) pg/mg for the second trimester, and 331.31 (295.46) pg/mg for the third trimester of pregnancy. None of the assessed confounding variables (age, body mass index, previous miscarriages, employment status, hair dyes, dependent children and physical exercise), except education level, was related to HCC. CONCLUSIONS: In this sample of healthy Spaniards, results suggested an association between HCC and physical exercise and educational level. In pregnant women, the prevalence of HCC was higher than in non-pregnant woman, and was related to educational level. This study emphasises the need to determine the relationship between HCC and confounders such as sociodemographic and lifestyle variables in the general population and specific groups formed by individuals such as pregnant women.

The relationship between the menstrual cycle and cortisol secretion: Daily and stress-invoked cortisol patterns.

The menstrual cycle involves significant changes in hormone levels, causing physical and psychological changes in women that are further influenced by stress. The aim of this study was to understand the relationship between menstrual cycle phase and salivary cortisol patterns during the day as well as the salivary cortisol response to the Virtual Reality Version of the Trier Social Stress Test (TSST-VR). Forty two women not taking oral contraceptives (24 in follicular phase and 18 in luteal phase) participated in the study. Five samples of salivary cortisol collected during the day and another five samples of cortisol during the TSST-VR were analyzed. Psychological stress measures and psychopathological symptomatology were also evaluated. A 2 × 4 mixed ANCOVA showed an interaction between the two groups on the TSST-RV invoked cortisol response to the [F(3,42) = 3.681; p = 0.023) where women in luteal phase showed higher cortisol post exposure levels (5.96 ±â€¯3.76 nmol/L) than women in follicular phase (4.31 ±â€¯2.23 nmol/L). No other significant differences were found. Our findings provide evidence that menstrual cycle phase tended to influence cortisol response to laboratory-induced mental stress, with more reactivity observed in the luteal phase.

Association between perceived level of stress, clinical characteristics and psychopathological symptoms in women with systemic lupus erythematosus.

OBJECTIVES: To evaluate psychopathological status and stress level from a sample with SLE; compare mental functioning and stress levels between women with SLE and healthy women; determine whether disease duration, disease activity, cumulative organ damage and stress have an influence on psychopathological symptoms in SLE patients; and evaluate whether perception of stress is related to SLE severity. METHODS: We conducted a cross-sectional study of 425 participants; 202 women with SLE, with an average age (SD) of 36.61 (10.15), and 223 healthy women, with age-matched controls. The assessment included the clinical characteristics (disease duration, SLE activity, cumulative organ damage, pharmacotherapy), the Symptom Checklist-90-Revised (SCL-90-R) and the Perceived Stress Scale. Descriptive, comparative, univariate and multivariate analysis were performed. RESULTS: SLE patients showed psychopathological alterations in the somatisation, obsessive-compulsive and positive discomfort subscales of SCL-90-R. Women with SLE reported significantly higher scores on the psychopathological dimensions and perceived stress compared to healthy women, except for paranoid ideation. Disease duration, SLE activity, cumulative organ damage, and perceived stress were shown to be significant predictors of psychopathological manifestations, explaining a range, between 20 and 43%, of variance across SCL-90-R dimensions. Moreover, perceived stress was related to SLE activity, after controlling for psychopathological dimensions. CONCLUSIONS: The psychopathological manifestations in SLE appeared to be influenced by perceived stress, disease duration, disease activity and cumulative organ damage. In turn, perceived stress was associated with disease severity. This knowledge may contribute to a more comprehensive perspective of these manifestations in the SLE population in the clinical setting.

Analyses of hair and salivary cortisol for evaluating hypothalamic-pituitary-adrenal axis activation in patients with autoimmune disease.

Although many studies have shown that patients with autoimmune disease present a hypoactive hypothalamic-pituitary-adrenal axis (HPA), controversial results have been described. Our objective was to study HPA axis activity in women with autoimmune disease compared to healthy women. Therefore, we analyzed salivary cortisol over the course of a day, and hair cortisol concentrations from the three preceding months, from 65 women divided into two groups: healthy women (n = 30), with a mean age of 44.70 ± 11.65 years; and women with autoimmune disease (n = 35), with a mean age of 48.26 ± 9.04 years. The latter group comprises women with systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), and systemic sclerosis (SSc). Perceived stress and psychopathological symptomatology were also evaluated. Autoimmune disease group scored higher on the somatization subscale SCL-90-R and lower on the anxiety subscale than the control group. Regarding HPA axis activation, the area under curve for cortisol levels during the day was higher for the autoimmune disease group. In addition, higher cortisol levels in hair were found in the group with autoimmune disease. Our findings show greater short and long-term HPA axis activity in women with autoimmune disease than in healthy women.

A virtual reality approach to the Trier Social Stress Test: Contrasting two distinct protocols.

Virtual reality adaptations of the Trier Social Stress Test (TSST-VR) constitute useful tools for studying the physiologic axes involved in the stress response. Here, we aimed to determine the most appropriate experimental approach to the TSST-VR when investigating the modulation of the axes involved in the stress response. We compared the use of goggles versus a screen projection in the TSST-VR paradigm. Forty-five healthy participants were divided into two groups: the first one (goggles condition; 13 females, 11 males) wore goggles while performing the TSST-VR; the second (screen condition; 15 females, six males) was exposed to the TSST-VR projected on a screen. Sympathetic reactivity to stress was measured by continuously recording skin conductance (SC), while the hypothalamic-pituitary-adrenal axis (HPA) was evaluated by sampling salivary cortisol throughout the experiment. At the end of the task, there was an increase in SC and cortisol level for both means of delivering the TSST-VR, although the increase in SC was greater in the goggles condition, while salivary cortisol was comparable in both groups. Immersion levels were reportedly higher in the screen presentation than in the goggles group. In terms of sex differences, females experienced greater involvement and spatial presence, though comparatively less experienced realism, than their male counterparts. These findings help us determine which protocol of the TSST-VR is most suitable for the stress response under study. They also emphasize the need to consider the sex of participants, as males and females show distinct responses in each protocol.
