Adverse childhood experiences predict reaction to multiple sclerosis diagnosis

Resilience, mental health, sleep, and smoking mediate pathways between lifetime stressors and Multiple Sclerosis severity

Intro

Lifetime stressors (e.g., poverty, violence, discrimination) have been linked to Multiple Sclerosis (MS) features; yet mechanistic pathways and relationships with cumulative disease severity remain nebulous. Further, protective factors like resilience, that may attenuate the effects of stressors on outcomes, are seldom evaluated.

Aim

To deconstruct pathways between lifetime stressors and cumulative severity on MS outcomes, accounting for resilience.

Methods

Adults with MS (N=924) participated in an online survey through the National MS Society listserv. Structural Equation Modeling was used to examine the direct and indirect effect of lifetime stressors (count/severity) on MS severity (self-reported disability, relapse burden, fatigue, pain intensity and interference), via resilience, mental health (anxiety and depression), sleep disturbance, and smoking.

Results

The final analytic model had excellent fit (GFI=0.998). Lifetime stressors had a direct relationship with MS severity (β=0.27, p<.001). Resilience, mental health, sleep disturbance, and smoking significantly mediated the relationship between lifetime stressors and MS severity. The total effect of mediation was significant (β=0.45).

Conclusions

This work provides foundational evidence to inform conceptualization of pathways by which stress could influence MS disease burden. Resilience may attenuate effects of stressors, while poor mental health, smoking, and sleep disturbances may exacerbate their impact. Parallel with usual care, these mediators could be targets for early multimodal therapies to improve disease course.

Fatigue, pain interference, and psychiatric morbidity in multiple sclerosis: The role of childhood stress

BACKGROUND

Multiple sclerosis (MS) is a progressive, autoimmune disease of the central nervous system that affects nearly one million Americans. Despite the existence of immunomodulatory therapies to slow physical and cognitive disability progression, interventions to ameliorate common symptoms of MS, including fatigue and pain, remain limited. Poor understanding of risk factors for these symptoms may contribute to treatment challenges. In recent years, childhood stress has been investigated as a risk factor for chronic autoimmune conditions including MS; yet remarkably few studies have investigated the relationship between childhood stressors and chronic MS symptoms. Our aim was to examine clusters of stressors and three key features of MS: fatigue, pain interference, and psychiatric morbidity.

METHODS

Cross-sectional data were collected from a sample of People with MS (PwMS) via a national web-based survey that assessed the presence and type of childhood stressors and MS clinical features. Hierarchical block regression was used to assess associations among emotional, physical, and environmental childhood stressors and three clinical features commonly experienced by PwMS.

RESULTS

N = 719 adults with MS (aged 21-85) completed the survey. Childhood emotional and physical stressors were significantly associated with overall presence of fatigue (p = 0.02; p<0.03) and pain interference (p<0.001; p<0.001) in adulthood, as well as the magnitude of both outcomes. Environmental stressors (p<0.001), in addition to emotional (p<0.001) and physical (p<0.001) stressors were significantly associated with psychiatric morbidity in PwMS.

CONCLUSION

Childhood stress may predict fatigue, psychiatric morbidity, and pain in adults with MS. Further research is needed to show cause and effect; however, if an association exists, strategies to mitigate the impact of childhood stress could offer new pathways to reduce the severity of these symptoms. Broadly, this work adds to the body of evidence supporting upstream preventive measures to help address the stress on children and families.

Adverse childhood experiences in early life increase the odds of depression among adults with multiple sclerosis

Background

Adverse childhood experiences are demonstrated risk factors for depression, a common co-morbidity of multiple sclerosis, but are understudied among people with multiple sclerosis.

Objective

Estimate the association between adverse childhood experiences and depression among 1,990 adults with multiple sclerosis.

Methods

Participants were members of Kaiser Permanente Northern California from two studies between 2006 and 2021 and were diagnosed with multiple sclerosis by a neurologist. Adverse childhood experiences were assessed using two instruments, including the Behavioral Risk Factor Surveillance System. Participants self-reported ever experiencing a major depressive episode. Meta-analysis random effects models and logistic regression were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) to assess the relationship between adverse childhood experiences and a history of depression across study samples. Adverse childhood experiences were expressed as any/none, individual events, and counts. Models adjusted for sex, birth year, race, and ethnicity.

Results

Exposure to any adverse childhood experiences increased the odds of depression in people with multiple sclerosis (OR: 1.71, 95% CI: 1.21-2.42). Several individual adverse childhood experiences were also strongly associated with depression, including "significant abuse or neglect" (OR: 2.79, 95% CI: 2.11-3.68).

Conclusion

Findings suggest that adverse childhood experiences are associated with depression among people with multiple sclerosis. Screening for depression should be done regularly, especially among people with multiple sclerosis with a history of adverse childhood experiences.

Association of adverse childhood experiences with adulthood multiple sclerosis: A systematic review of observational studies

INTRODUCTION

Adverse childhood experiences (ACEs) are proposed to increase the risk of developing multiple sclerosis (MS) later in life. This systematic review aimed to explore the correlation between ACEs and MS development, age of onset, quality of life in MS patients and MS relapse rates.

METHODS

We searched a total of six databases in June 2022 and retrieved the relevant studies. The population included adult (18+) individuals who either had been diagnosed or were at risk for developing MS and also had exposure to ACEs. Our primary outcomes include the risks of MS development, age of MS onset, and MS relapse rate in patients who were exposed to different types of ACEs.

RESULTS

A total of 11 studies were included in our review. A study reported that among 300 women diagnosed with MS, 71 (24%) reported a history of childhood abuse; moreover, with further research, it was concluded that ACEs were associated with the development of MS. Abuse that occurred 2-3 times per week was associated with an 18.81-fold increased risk of having MS when compared to the unexposed sample. The relapse rate of MS was found to be substantially greater in severe cases of ACEs compared to individuals who did not report any ACEs.

CONCLUSIONS

Results support a significant association between ACEs and the development of MS; individuals with a positive history of ACEs develop MS symptoms earlier. Moreover, the severity of ACEs is also linked with increased relapse rates of MS.

[Observations on the influence of trauma-centered psychotherapy with EMDR therapy on somatic comorbidities using the example of Hashimoto's autoimmune thyroiditis]

BACKGROUND

Results of modern research show a relationship between emotional stress and the occurrence of autoimmune diseases as a comorbidity. The authors use EMDR therapy (Eye Movement Desensitization and Reprocessing) to treat trauma disorders. They wondered whether and to what extent this treatment also affects autoimmune processes.

METHOD

Parallel to the trauma-focused psychotherapy with EMDR, the thyroid hormone substitution dose was documented in patients with active Hashimoto's autoimmune thyroiditis requiring substitution. Hashimoto's autoimmune thyroiditis had already been diagnosed by a specialist and drug treatment had been initiated before starting outpatient psychotherapy.

RESULTS AND CONCLUSION

So far in five cases a decrease in autoimmune activity and a stability of the results in the follow-up between six months and one year could be observed. It is now necessary to examine whether these results can be confirmed in a larger number of patients and a diversity of therapists and whether these observations can be transferred to other somatic comorbidities.

Relationships between childhood trauma and multiple sclerosis: A systematic review

OBJECTIVE

Adverse Childhood Experiences (ACEs), such as physical, emotional, and sexual abuse trigger inflammatory changes and have been associated with many causes of morbidity and mortality, including autoimmune diseases. Although Multiple Sclerosis (MS) is a debilitating neurological autoimmune disease, literature linking ACEs and MS is understudied. The aim of this review was to examine the 1) state of the literature, and 2) relationships between childhood adversity and the prevalence and physical clinical features of MS (e.g., age at onset, relapses, pain, fatigue, disability).

METHODS

A comprehensive search was preformed through five databases and by hand using the ancestry and descendancy approach for connections to papers published through January 20th, 2022. Studies were screened by independent reviewers using Rayyan.ai, and critically appraised for both quality and reporting transparency.

RESULTS

Twelve studies examined relationships between any ACE(s) and the prevalence or physical clinical features of MS. There was considerable variance in the measurement of stressors, confounders, and categorization of MS; however most studies (n = 10) demonstrated an association between ACEs and MS (alone or grouped with other similar diagnoses), or physical clinical features.

CONCLUSION

Although there are few studies in this area, it is of quickly growing interest. These results should be cautiously interpreted, yet highlight the need for continued work to disentangle and discern true associations.
