# The Impact of Stress on Autoimmune Disorders: Type 1 Diabetes Mellitus and Systemic Lupus Erythematosus

## TL;DR

This paper reviews how stress affects autoimmune diseases like type 1 diabetes and lupus, focusing on how stress impacts immune function and disease progression.

## Contribution

The paper provides a comprehensive review of stress's role in autoimmune diseases, emphasizing neuroendocrine pathways and immune dysregulation.

## Key findings

- Stress can trigger type 1 diabetes in genetically predisposed individuals by disrupting immune function before diagnosis.
- In systemic lupus erythematosus, stress is linked to disease flares due to immune dysregulation and cytokine imbalance.
- Stress influences autoimmune diseases through neuroendocrine pathways like the HPA axis and glucocorticoid effects.

## Abstract

Autoimmune disorders, including type 1 diabetes mellitus (T1DM) and systemic lupus erythematosus (SLE), are influenced by a combination of genetic, environmental, and immunological factors. Among these, stress, both physical and psychological, has been increasingly recognized as a significant contributor to disease onset and progression. This review explores the current literature on the relationship between stress and autoimmune diseases, focusing on the neuroendocrine pathways, such as the hypothalamic-pituitary-adrenal (HPA) axis, and the effects of glucocorticoids on immune modulation. These mechanisms contribute to clinical manifestations, such as disease flares or progression, highlighting the impact of stress on patient outcomes. Evidence suggests that psychological stress can precipitate the onset of T1DM in genetically predisposed individuals, with immune disruptions occurring before diagnosis. In SLE, both acute and chronic stress, particularly trauma-induced stress, has been linked to increased disease activity and flare-ups, largely due to stress-induced immune dysregulation that disrupts the balance between pro-inflammatory and anti-inflammatory cytokines. Despite the substantial evidence supporting the role of stress in autoimmune disease exacerbation, further research is necessary to fully understand the mechanisms by which stress influences autoimmune diseases and to develop effective stress management.
