Celiac.com 02/03/2026 - Celiac disease is an immune-based condition in which the body reacts abnormally to gluten, a protein found in wheat, barley, and rye. When a child with celiac disease eats gluten, the immune system attacks the lining of the small intestine. Over time, this reaction damages the intestinal surface, making it difficult to absorb nutrients properly. While celiac disease is best known for its digestive symptoms, it is also closely linked to the immune system and can overlap with other autoimmune conditions.
Autoimmune diseases often cluster together, meaning that a person with one autoimmune condition is more likely to develop others. In children with celiac disease, doctors have long observed higher rates of immune conditions affecting the thyroid gland and the body’s regulation of blood sugar. These conditions are often detected through specific immune markers in the blood known as autoantibodies. This study explored whether the presence of certain endocrine-related autoantibodies is linked to how severe the intestinal damage is in children with celiac disease.
Why Endocrine Autoantibodies Matter
Celiac.com Sponsor (A12):
Endocrine autoantibodies are immune proteins that mistakenly target hormone-producing tissues in the body. Some are linked to thyroid dysfunction, while others are associated with problems in insulin regulation. Even when a child does not yet show symptoms of thyroid disease or blood sugar disorders, the presence of these autoantibodies can signal immune activity that may affect long-term health.
Researchers wanted to know whether these autoantibodies were simply additional findings or whether they were connected to more serious intestinal injury in celiac disease. If such a connection exists, these immune markers could help doctors identify children who are at higher risk for severe disease and complications.
How the Study Was Conducted
This research reviewed the medical records of children diagnosed with celiac disease over a period spanning more than a decade. Only children who had been followed for at least two years and had available blood tests for endocrine autoantibodies were included. This allowed the researchers to evaluate both immune markers and long-term disease features.
The investigators collected information on age, sex, clinical symptoms, laboratory findings, and intestinal biopsy results. Intestinal biopsies are a key tool in diagnosing celiac disease and assessing its severity. These samples show how much damage has occurred to the finger-like structures in the intestine that absorb nutrients. Greater damage reflects more severe disease.
The Children Included in the Study
The study included nearly two hundred and fifty children and adolescents, ranging from early childhood through the teenage years. Most of the participants were girls, which reflects the known pattern of autoimmune diseases being more common in females. The typical child in the study was around early adolescence at the time of diagnosis.
All participants had confirmed celiac disease, and a significant number showed advanced intestinal damage at diagnosis. This allowed the researchers to examine whether immune markers outside the intestine were associated with worse tissue injury.
Presence of Endocrine Autoantibodies
About one in five children in the study tested positive for at least one endocrine-related autoantibody. An important finding was that all children with these autoantibodies were ten years of age or older. This suggests that immune changes related to endocrine organs may become more apparent as children with celiac disease get older.
The presence of these autoantibodies did not necessarily mean that a child had already developed another autoimmune disease. Instead, they indicated heightened immune activity that could influence how celiac disease behaves in the body.
Link Between Autoantibodies and Intestinal Damage
One of the most significant findings of the study was the strong association between endocrine autoantibodies and severe intestinal injury. Children who tested positive for these immune markers were more likely to have extensive damage to the intestinal lining. In many cases, the normal structure of the intestine was almost completely flattened, a sign of advanced disease.
When the researchers examined multiple factors together, such as age and sex, the presence of endocrine autoantibodies stood out as the only factor independently linked to more severe intestinal damage. This suggests that these immune markers are not just coincidental findings but may reflect a more aggressive immune response overall.
What These Findings Suggest About the Immune System
The results point to a broader pattern of immune involvement in some children with celiac disease. Rather than being limited to the gut, the immune system in these children may be more globally active, affecting multiple tissues at once. This could explain why some children experience more severe disease and are more prone to developing additional autoimmune conditions.
The study also raises the possibility that endocrine autoantibodies could serve as warning signs. Their presence may indicate that the immune system is particularly reactive, which could influence how quickly intestinal damage progresses or how well a child responds to treatment.
Limitations and the Need for Further Research
Because this study looked back at existing medical records, it could not determine whether endocrine autoantibodies directly cause more severe intestinal damage or whether both arise from the same underlying immune tendency. The research also did not track whether children with these autoantibodies eventually developed thyroid or blood sugar disorders.
Future studies that follow children from diagnosis over time will be important. Such research could help determine whether autoantibodies can predict long-term outcomes and whether early intervention could change the course of disease.
Why This Study Matters for People with Celiac Disease
For families and individuals affected by celiac disease, this study highlights the importance of looking beyond digestive symptoms alone. The findings suggest that children with certain immune markers may have more severe intestinal damage and may need closer monitoring.
Understanding the broader immune landscape in celiac disease can help doctors tailor follow-up care, identify children at higher risk for complications, and possibly detect additional autoimmune conditions earlier. For people living with celiac disease, this research reinforces the idea that the condition is part of a larger immune process, not just a reaction to food.
In the long term, recognizing immune markers linked to disease severity could lead to more personalized care and improved outcomes. By shedding light on how endocrine autoantibodies relate to intestinal damage, this study offers valuable insight into why celiac disease affects individuals differently and how better monitoring could improve quality of life.
