Why is type 1 diabetes an autoimmune disease

However, symptoms can become more obvious if the condition worsens. Kids with hypothyroidism also might have slow growth in height, slow sexual development, irregular menstrual periods in girls, muscle weakness, dry skin, hair loss, poor memory, and difficulty concentrating.

Kids with thyroid problems might be prescribed medication to bring their thyroid hormone levels back to normal. When kids with celiac disease eat foods containing gluten, their immune systems react to it, causing gastrointestinal symptoms. Over time, exposure to gluten damages the small intestine and prevents it from properly absorbing nutrients from food. Some people have no symptoms, but others may have frequent diarrhea, abdominal pain, gas, bloating, weight or appetite loss, or fatigue.

If not treated, celiac disease can lead to hypoglycemia , osteoporosis a disease that causes brittle, fragile bones , and certain types of cancer. If your child has type 1 diabetes, your doctor may do a blood test to check for celiac disease, even if there are no symptoms. If the doctor suspects celiac disease, your child might undergo a small-bowel biopsy the removal of a piece of tissue from the small intestine for examination to confirm the diagnosis.

Kids and teens who have celiac disease must follow a gluten-free diet no wheat, rye, and barley products. These glands, located just above the kidneys, produce hormones, including cortisol and aldosterone, that help control many body functions, particularly those related to its response to stress. These can include fatigue, muscle weakness, appetite loss, or weight loss. Some people experience nausea, vomiting, diarrhea, dizziness and low blood pressure, skin discoloration especially in skin creases, like the elbows , irritability, depression, or irregular periods.

These symptoms can be more severe and come on suddenly. This is called an addisonian crisis, or acute adrenal insufficiency. The condition is treated with medication to bring adrenal hormone levels back to normal. Knowing which signs and symptoms to watch for and making sure your child gets regular checkups and the tests recommended by your doctor will help reduce or prevent the effects of these disorders.

Table 3 summarizes the disease specificity of GAD autoantibodies. GAD autoantibodies were originally identified in patients with stiff-person syndrome regardless of the coexistence of T1D We and others have previously reported the association between anti-thyroid autoimmunity and anti-islet autoantibodies, especially autoantibodies to GAD.

In this article, I reviewed the recent knowledge regarding the autoimmune diseases associated with T1D and anti-islet autoantibodies. Although the underlying mechanisms with respect to the development of multiple autoimmune diseases within the same person are largely unknown, recent progress including the identification of several loci with associations to more than one autoimmune disease 19 suggests that common genetic factors or immunological processes are present among the different autoimmune diseases.

As the most common coexisting organ-specific autoimmune disease associated with Japanese T1D is autoimmune thyroid disease, children with T1D, or with a family history of T1D, should be aware of the tendency to develop additional autoimmune disorders, especially autoimmune thyroid disease. The clinical utilities of anti-islet autoantibodies in patients with diabetes include diagnosis type 1A or type 1B , prediction progressor or non-progressor and understanding of pathophysiology insulitis-specific or nonspecific phenomenon Fig.

It is especially necessary to pay attention to the interpretation of GAD autoantibodies. The development of a high-throughput assay to detect epitope-specific or immunoglobulin isotype-specific autoantibodies should warrant accurate diagnosis and prediction of autoimmune disorders.
