Autoimmune polyendocrine syndrome type 1 (APS-1) is a rare, inherited autoimmune disorder. It is caused by a genetic mutation that affects the body’s ability to regulate the immune system. People with APS-1 may have multiple autoimmune diseases, including Addison’s disease, which affects the adrenal glands; hypoparathyroidism, which affects the parathyroid glands; and type 1 diabetes, which affects the pancreas. Other autoimmune conditions may also be present, including autoimmune thyroiditis, vitiligo, alopecia areata, and pernicious anemia.
The main symptoms of APS-1 include fatigue, weight loss, and muscle weakness. Patients may also experience depression, anxiety, and difficulty concentrating. In addition, patients may have low blood pressure, low blood sugar, and hypoglycemia.
Diagnosis of APS-1 is based on a blood test that detects autoantibodies. Treatment may include corticosteroids, immunosuppressive agents, and intravenous immunoglobulin therapy. Other treatments may include lifestyle modifications and dietary changes.
APS-1 is a serious disorder that can be life-threatening. Early diagnosis and treatment are essential to prevent complications. Patients with APS-1 should be monitored closely by a healthcare provider and take all prescribed medications as directed.
