Autoimmune diseases are a significant health concern, impacting over 23.5 million Americans. These diseases are a leading cause of death and disability. While some autoimmune diseases are considered rare, others, like Hashimoto’s disease, are quite prevalent.
Regardless of your specialty, encountering patients with autoimmune diseases is becoming more prevalent. Gaining a better understanding of autoimmune diseases’ general pathology and causes can help physicians better recognize and provide early, effective treatment.

Pathogenesis of autoimmune diseases
The development of autoimmune diseases such as multiple sclerosis, Type-1 diabetes, rheumatoid arthritis, and inflammatory bowel disease is generally attributed to a breakdown in the body’s tolerance to its own cells. The specific initiating events that trigger these diseases remain largely unknown. However, they may be linked to a variety of overstimulated immune responses.
Key factors include the loss of co-stimulatory control by antigen-presenting cells and a phenomenon known as “molecular mimicry.” In this phenomenon, immune cells designed to target external threats mistakenly attack similar self-antigens. Consequently, once an immune reaction is set in motion, a large invasion of immune cells occurs, coupled with a systemic immune response that leads to tissue damage and the exposure of more self-antigens.
Risk factors for autoimmune diseases
Although certain genetic predispositions for autoimmune diseases have been identified, they only explain a small portion of the overall incidence. Therefore, external or exogenous factors are believed to play a significant role in these diseases.
Research conducted over recent decades supports this view. It indicates that many autoimmune diseases arise from a combination of genetic vulnerabilities and environmental influences. The rising rates of these diseases, particularly in Western countries, have led to various hypotheses to explain these trends.
In addition to infections, numerous other environmental factors have been proposed to contribute to the development of autoimmune diseases. These include climate, stress, occupational hazards, cigarette smoking, and dietary choices. Notably, consuming “Westernized” foods—characterized by high levels of salt, fat, protein, and sugar—has been linked to the increasing prevalence rates of various diseases.
Research into changing dietary habits reveals a direct impact on immune homeostasis and the bacterial communities inhabiting the gastrointestinal tract. The gut microbiota is intricately connected to immune function and plays a critical role in regulating immune processes. Alterations in the microbiome have been associated with IBD and a range of other autoimmune diseases, even those not primarily affecting the gastrointestinal tract.
Despite these insights, experts still do not understand the exact mechanisms that connect environmental factors to disease development, genetic predisposition, and immune response. Continued exploration of how environmental aspects and microbiota influence immune homeostasis holds promise for enhancing our understanding of the escalating incidence of autoimmune conditions.
Health literacy and autoimmune diseases
Health literacy is essential for effective healthcare. It equips individuals with the ability to read, comprehend, and utilize medical information when making health-related decisions. This skill goes beyond basic literacy. It encompasses navigation of healthcare systems, calculation of medication doses, interpretation of test results, understanding of surgical instructions, and evaluation of nutritional labels for allergens.
Individuals with low health literacy are at a higher risk for adverse health outcomes. They frequently encounter medication errors, struggle to manage chronic conditions like autoimmune diseases, and may overlook important preventive services. In contrast, those with proficient health literacy are more likely to actively participate in their healthcare. This can lead to improved health outcomes and longer, healthier lives.
Integrating a patient-centered care model is crucial for enhancing health literacy. This approach prioritizes the patient in the healthcare process. It aims to improve patient engagement by assessing health literacy levels within healthcare organizations. It supports a fair, inclusive health ecosystem that empowers patients to make informed choices.
Key strategies to promote health literacy
- Simplifying health education materials.
- Ensuring materials are culturally relevant and sensitive.
- Providing information in various formats (audio, visual, print) to accommodate different learning styles.
- Implementing assistive care between doctor visits to engage patients in their health education.
- Conducting outreach programs in community centers, schools, and workplaces to expand the reach of health education.
By employing these focused strategies, physicians and healthcare systems can play a crucial role in creating a more informed public. They can equip patients with the knowledge necessary to make better health decisions and achieve improved health outcomes.
Considerations for non-English-proficient patients
Limited English Proficiency (LEP) refers to individuals whose primary language is not English. They may also experience challenges in effectively communicating in English. Healthcare providers should recognize that patients and families with LEP require additional support to engage as effective partners in healthcare discussions.
To ensure meaningful access for patients with LEP, practices must take reasonable steps tailored to the specific needs of their community. What constitutes “reasonable” actions can vary based on factors such as:
- Proportion of LEP individuals in the practice area
- Frequency of LEP cases in the office
- Critical nature of the service to the patient
- Availability and cost of interpretation services
For instance, a practice located in a community with a significant number of Spanish-speaking residents might consider hiring bilingual staff or an on-site interpreter. They might consider providing written materials in both English and Spanish.
Avoid using a family member as an interpreter. This practice raises concerns about confidentiality, the accurate interpretation of medical terminology, and the risk of withheld information. Engaging professional interpreters fosters better communication, reduces errors, enhances comprehension, improves clinical outcomes, and boosts patient satisfaction.
Cultural competency plays a vital role in reducing healthcare disparities among diverse populations. Clinicians need to be aware of their patients’ beliefs about health, healing, and wellness, as well as their perceptions of illness and its causes. Understanding health behaviors, attitudes toward healthcare providers, and family roles in decision-making is essential for building a successful patient-clinician relationship and achieving optimal health outcomes.
Role of healthcare practitioners
An autoimmune disease can impact any body system, weakening bodily function, and even become life-threatening. Despite this significant burden, the individual study of these diseases has led to an under-appreciation of their overall health impact. As chronic conditions without a known cure, autoimmune diseases necessitate lifelong management. Autoimmune diseases contribute to considerable morbidity, disability, and mortality.
Healthcare professionals, particularly those in primary care, encounter several challenges in diagnosing and managing autoimmune diseases. The initial symptoms are often nonspecific and overlap with those of other diseases. This makes it difficult to pinpoint a diagnosis early on. Furthermore, guidelines offer limited recommendations for the diagnosis and management of these diseases.
As a result, individuals may experience a prolonged period before receiving a definitive diagnosis. Even once diagnosed, they may not always receive the most effective treatments available. Regular follow-up is essential for monitoring treatment responses, managing side effects, and preventing related health issues. An important function of healthcare professionals is to encourage and involve patients in the decision-making process and educate them on self-management strategies.
