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.

Effect of COVID-19 confinement on the mental status of patients with systemic lupus erythematosus.

BACKGROUND AND OBJECTIVE: Patients with systemic lupus erythematosus (SLE) are more vulnerable to higher levels of stress and psychopathological symptoms than the general healthy population. Therefore, the COVID-19 outbreak could alter their psychological state. The objective was to analyze the psychological impact of the pandemic and confinement on stress levels and psychopathological symptoms in patients with SLE. PATIENTS AND METHOD: In this cross-sectional study, stress levels were compared with the Perceived Stress Scale, the Stress Vulnerability Inventory and psychopathological symptoms of the SCL-90-R Symptom Inventory in patients with SLE during the period of confinement (group 1; n = 276) in comparison to patients with SLE evaluated in a period before the pandemic (group 2; n = 152). RESULTS: The comparison between both groups showed there were statistically significant differences in vulnerability to stress (p < 0.0001), depression (p ≤ 0.05), anxiety (p ≤ 0.05), phobic anxiety (p < 0.0001), interpersonal sensitivity (p ≤ 0.043), and psychoticism (p ≤ 0.023). In these variables, the group of patients with lupus in confinement obtained higher scores. CONCLUSIONS: The confinement and threat of the COVID-19 outbreak had important repercussions on the psychological state of patients with SLE with high levels of stress, anxiety, and depression. These findings show their vulnerability to a public health alert and indicate the need to carry out a psychological approach to these patients while the state of health emergency lasts as well as to possible outbreaks of the virus.

ANTECEDENTES Y OBJETIVO: Las pacientes con lupus eritematoso sistémico (LES) son más vulnerables a presentar mayores niveles de estrés y síntomas psicopatológicos que la población general sana, por lo que el brote de la COVID-19 podría alterar su estado psicológico. El objetivo fue analizar el impacto psicológico de la pandemia y del confinamiento sobre los niveles de estrés y sintomatología psicopatológica en pacientes con LES. PACIENTES Y MÉTODO: En este estudio transversal se compararon niveles de estrés mediante la Escala de Estrés Percibido y el Inventario de Vulnerabilidad al Estrés, y síntomas psicopatológicos mediante el Inventario de síntomas SCL-90-R, en pacientes con LES durante el período de confinamiento (grupo 1; n = 276) con respecto a pacientes con LES evaluadas en un período anterior a la pandemia (grupo 2; n = 152). RESULTADOS: La comparación entre ambos grupos mostró que existían diferencias estadísticamente significativas en vulnerabilidad al estrés (p < 0,0001), depresión (p ≤ 0,05), ansiedad (p ≤ 0,05), ansiedad fóbica (p < 0,0001), sensibilidad interpersonal (p ≤ 0,043), y psicoticismo (p ≤ 0,023). En estas variables el grupo de pacientes con lupus en confinamiento obtuvo puntuaciones superiores. CONCLUSIONES: El confinamiento y la amenaza del brote por COVID-19 ha tenido importantes repercusiones en el estado psicológico de las pacientes con LES, mostrando altos niveles de estrés, ansiedad y depresión. Estos hallazgos muestran su vulnerabilidad ante una alerta de salud pública, y señala la necesidad de realizar un abordaje psicológico de estas pacientes mientras dure el estado de emergencia sanitaria, así como ante posibles rebrotes del virus.

[This corrects the article DOI: 10.1371/journal.pone.0204807.].

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.

Association between burnout and cortisol secretion, perceived stress, and psychopathology in palliative care unit health professionals.

ABSTRACTObjective:A high incidence of burnout has been reported in health professionals working in palliative care units. Our present study aims to determine whether there are differences in the secretion of salivary cortisol between palliative care unit health professionals with and without burnout, and to elucidate whether there is a relationship between burnout syndrome and perceived stress and psychopathological status in this population. METHOD: A total of 69 health professionals who met the inclusion criteria participated in our study, including physicians, nurses, and nursing assistants. Some 58 were women (M = 29.65 years, SD = 8.64) and 11 men (M = 35.67 years, SD = 11.90). The level of daily cortisol was registered in six measurements taken over the course of a workday. Burnout syndrome was evaluated with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS), the level of perceived stress was measured using the Perceived Stress Scale, and psychopathological status was gauged using the SCL-90-R Symptoms Inventory. RESULTS: There were statistically significant differences in secretion of cortisol in professionals with high scores on a single subscale of the MBI-HSS [F(3.5) = 2.48, p < 0.03]. This effect was observed 15-30 minutes after waking up (p < 0.01) and at bedtime (p < 0.06). Moreover, the professionals with burnout showed higher scores on the psychopathology and stress subscales than professionals without it. SIGNIFICANCE OF RESULTS: A higher score in any dimension of the burnout syndrome in palliative care unit health professionals seems to be related to several physiological and psychological parameters. These findings may be relevant for further development of our understanding of the relationship between levels of burnout and cortisol secretion in the health workers in these units.

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.

Effects of the Cognitive-Behavioral Therapy for Stress Management on Executive Function Components.

This study aims to determine whether it is possible to modify executive function in stressed individuals by means of cognitive-behavioral therapy for stress management. Thirty-one people with high levels of perceived stress were recruited into the study (treatment group = 18; wait-list group = 13). The treatment group received 14 weeks of stress management program. Psychological and executive function variables were evaluated in both groups pre and post-intervention. The treatment group showed improved psychological variables of perceived stress (t = 5.492; p = .001), vulnerability to stress (t = 4.061; p = .001) and superstitious thinking (t = 2.961; p = .009). Likewise, the results showed statistically significant differences in personality variables related to executive function, positive urgency (t = 3.585; p = .002) and sensitivity to reward (t = -2.201; p = .042), which improved after the therapy. These variables showed a moderate to high effect size (oscillates between 1.30 for perceived stress and .566 for sensitivity to reward). The cognitive-behavioral therapy for stress management may be an appropriate strategy for improving personality construct components related to executive function, however effects of the therapy are not showed on performance on the tests of executive function applied, as presented studies previous.

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.

A relaxation technique enhances psychological well-being and immune parameters in elderly people from a nursing home: a randomized controlled study.

BACKGROUND: The aging process involves a decline in immune functioning that renders elderly people more vulnerable to disease. In residential programs for the aged, it is vital to diminish their risk of disease, promote their independence, and augment their psychological well-being and quality of life. METHODS: We performed a randomized controlled study, evaluating the ability of a relaxation technique based on Benson's relaxation response to enhance psychological well-being and modulate the immune parameters of elderly people living in a geriatric residence when compared to a waitlist control group. The study included a 2-week intervention period and a 3-month follow-up period. The main outcome variables were psychological well-being and quality of life, biomedical variables, immune changes from the pre-treatment to post-treatment and follow-up periods. RESULTS: Our findings reveal significant differences between the experimental and control groups in CD19, CD71, CD97, CD134, and CD137 lymphocyte subpopulations at the end of treatment. Furthermore, there was a decrease in negative affect, psychological discomfort, and symptom perception in the treatment group, which increased participants' quality of life scores at the three-month follow-up. CONCLUSIONS: This study represents a first approach to the application of a passive relaxation technique in residential programs for the elderly. The method appears to be effective in enhancing psychological well-being and modulating immune activity in a group of elderly people. This relaxation technique could be considered an option for achieving health benefits with a low cost for residential programs, but further studies using this technique in larger samples of older people are needed to confirm the trends observed in the present study.

[Impulsivity and compulsivity in cocaine dependent individuals]. / Impulsividad y compulsividad en individuos dependientes de cocaína.

A recent theoretical approach describes addiction as a dynamic behavioural change process on the impulsivity-compulsivity axis. However, on the basis of current evidence, it is still difficult to establish a selective association between the course of addiction and individual transition along this axis. The aim of this study is to categorize each of the individuals in a sample of cocaine-dependent patients (CDI) as mainly impulsive or mainly compulsive, on the basis of their performance in neuropsychological inhibition and perseveration tests, and to test the association between the assigned category and their scores in trait impulsivity, and severity of cocaine addiction (measured by means of self-report assessment tools). A total of 42 CDI and 65 healthy control individuals (HCI) were assessed using the UPPS-P Scale (to explore trait impulsivity), the Stroop and Go/No Go (to assess response inhibition), and Revised-Strategy Application and Probabilistic Reversal tests (to assess response perseveration). Forty-five per cent of the CDIs were classified as compulsive, and this subgroup scored significantly higher than the impulsive group on the UPPS-P dimensions of lack of perseverance and lack of premeditation. A substantial proportion of CDIs can be classified as compulsive. No differences between compulsive and impulsive CDIs were found with regard to severity of exposure to cocaine; however, patients classified as compulsive by means of neuropsychological tasks are less perseverative in the pursuit of long-term objectives and more prone to make under-meditated decisions, as shown by trait impulsivity assessment questionnaires.

Can decision-making skills affect responses to psychological stress in healthy women?

In recent studies showing how stress can affect an individual's decision-making process, the cognitive component of decision-making could also be considered a coping resource available to individuals when faced with a stressful situation. The Iowa Gambling Task (IGT) constitutes the standard test for the assessment of decision-making skills under conditions of uncertainty. Responses of the hypothalamic-pituitary-adrenal (HPA) axis to psychosocial stress, in turn, have been estimated by means of cortisol measurements. Our main objective in this study was to test if good and bad IGT performers show distinct HPA axis responses, when challenged in a classic psychosocial stress test. Because women have been shown to outperform men on the IGT under the influence of psychosocial stress, we chose a sample of 40 women to take the IGT before they were exposed to a public speaking task in a virtual environment. The activation of the HPA axis, involved in the stress response, was assessed by examining the levels of cortisol in the subjects' saliva at the following four stages: before the challenge, after the challenge, and 10 and 20 min after the task. Participants were divided into two groups according to their level of performance, good or poor, on the IGT. Results showed statistically significant differences between the groups for pre-exposure cortisol levels and for cortisol levels 20 min after exposure. Overall cortisol levels were significantly higher in the group with poor performance on the IGT. It appears that good decision-making, which may be an important resource for coping with stress, is associated with a lower HPA axis response to a psychosocial stressor.

[Adaptation and validation of the Spanish version of a disease-specific quality of life measure in patients with systemic lupus erythematosus: the Lupus quality of life]. / Adaptación y validación de la versión española de una medida específica de la calidad de vida en los pacientes con lupus eritematoso sistémico: el Lupus Quality of Life.

BACKGROUND AND OBJECTIVE: Systemic Lupus Erythematosus (SLE) is an auto-immune disease that seriously affects quality of life. There are various specific instruments that measure health-related quality of life (HRQOL), but none of them has been adapted to Spanish. We intended to adapt and validate in a Spanish population a specific HRQOL measure in patients with SLE. PATIENTS AND METHODS: The adaptation was carried out using the translation and back-translation method of the English version of the LupusQoL, with its subsequent application to 115 adults with SLE. RESULTS: The factorial analysis identified 5 domains of the LupusQoL; the reliability tests showed a high Cronbach alpha coefficient of 0.977 and a high Guttman two-halves coefficient of 0.936; the significant correlations of the LupusQoL with the SF-36 showed a high convergent validity of the questionnaire; in addition, the correlations with the SLEDAI and SLICC were low, which showed its discriminated validity. CONCLUSION: The Spanish version of the LupusQoL has stable psychometric properties to measure HRQOL in people with SLE in clinical and research settings in a Spanish-speaking population.
