Schmidt Syndrome is a polyglandular autoimmune condition. It is a hormonal dysfunction that affects two or more endocrine glands; other non-endocrine immune disorders are also present, e.g. idiopathic thrombocytopenic purpura, Sjogren’s syndrome, and rheumatoid arthritis. Common symptoms reported by people with Schmidt's syndrome.
What is Schmidt syndrome type 2?
DEFINITION Schmidt syndrome refers to the combination of autoimmune primary adrenal insufficiency (Addison’s disease) with autoimmune hypothyroidism and/or type 1 diabetes mellitus (T1DM), and is part of a larger syndrome known as autoimmune polyendocrine syndrome type 2 (APS-2) or polyglandular autoimmune syndrome type II (PAS II).
What are the possible complications of Schmidt syndrome?
Primary adrenal deficiency concerning autoimmune activity is the main condition associated with Schmidt syndrome. Patients also develop autoimmune hypothyroidism or type 1 diabetes mellitus with this syndrome. In some patients, only two of these conditions will be present.
What is Schmidt disease (APS2)?
Researchers have classified Schmidt disease as part of autoimmune polyendocrine syndrome type 2, or APS-2. Sometimes, APS-2 is rather referred to as polyglandular autoimmune syndrome type II, or PAS II for short. This is why there is often an interchangeable use of Schmidt syndrome, APS-2, and PAS II.
What is Schmidt disease (Addison's disease)?
This autoimmune condition is also known as Addison’s disease. In addition to adrenal insufficiency, the patient may also develop: Researchers have classified Schmidt disease as part of autoimmune polyendocrine syndrome type 2, or APS-2.
What are the symptoms of Schmidt's syndrome?
Fatigue, anorexia, dizziness, muscle and joint pain, decreased libido may be some of the clinical features at the early stages of the disease [8]. Psychiatric manifestations are also well-documented [9].
How do you test for autoimmune Polyendocrine syndrome?
APS-1 is diagnosed definitively through DNA analysis (via blood test) of mutations in the AIRE gene. The diagnosis should be strongly considered in people under 30 years of age who present with at least two of the three typical disease components (CMC, hypoparathyroidism, and/or Addison's disease).
What is Polyendocrine syndrome?
Autoimmune polyendocrine syndrome is a rare, inherited disease in which the immune system mistakenly attacks many of the body's tissues and organs. The mucous membranes and adrenal and parathyroid glands are commonly affected, though other tissues and organs may become involved as well.
What is Type 2 polyglandular autoimmune syndrome?
Summary. Autoimmune polyglandular syndrome type 2 is an autoimmune disorder that affects many hormone-producing (endocrine) glands. It is characterized by the presence of Addison's disease along with autoimmune thyroid disease and/or type 1 diabetes.

Common autoimmune disorders include:Addison disease.Celiac disease - sprue (gluten-sensitive enteropathy)Dermatomyositis.Graves disease.Hashimoto thyroiditis.Multiple sclerosis.Myasthenia gravis.Pernicious anemia.More items...•
What autoimmune diseases cause low cortisol levels?
Overview. Addison's disease, also called adrenal insufficiency, is an uncommon disorder that occurs when your body doesn't produce enough of certain hormones. In Addison's disease, your adrenal glands, located just above your kidneys, produce too little cortisol and, often, too little aldosterone.
How is Schmidt's syndrome treated?
CLINICAL TREATMENT Treatment of primary hypothyroidism: physiologic thyroid hormone replacement with levothyroxine. Typical replacement dose is 1.6 mcg/kg per day (lower doses in elderly and those with cardiac disease) and adjusted every 4-6 weeks initially to maintain TSH and thyroxine levels in the mid normal range.
What autoimmune diseases cause yeast infections?
Women who take corticosteroids for asthma or a TNF inhibitor for autoimmune diseases, such as rheumatoid arthritis, lupus, or inflammatory bowel disease, are more likely to develop an overgrowth of yeast.
What blood tests are ordered for autoimmune diseases?
The antinuclear antibody (ANA) immunofluorescence assay (IFA) is a first-line screening test for patients with a suspected autoimmune disease. This test is the gold standard because of its high sensitivity compared to other assays.
Is Addison's disease related to thyroid?
People with Addison's disease often have an underactive thyroid (hypothyroidism), where the thyroid gland does not produce enough hormones. By testing the levels of certain hormones in your blood, your endocrinologist (a specialist in hormone conditions) can determine whether you have hypothyroidism.
How many autoimmune diseases can you have?
If you have an autoimmune disease, your immune system attacks the healthy cells of your organs and tissues by mistake. There are more than 80 types of autoimmune diseases. They can affect almost any part of your body. For example, alopecia areata is an autoimmune disease of the skin that causes hair loss.
How do you test for Addison disease?
Blood test. Tests can measure your blood levels of sodium, potassium, cortisol and adrenocorticotropic hormone (ACTH), which stimulates the adrenal cortex to produce its hormones. A blood test can also measure antibodies associated with autoimmune Addison's disease.
What blood tests are ordered for autoimmune diseases?
The antinuclear antibody (ANA) immunofluorescence assay (IFA) is a first-line screening test for patients with a suspected autoimmune disease. This test is the gold standard because of its high sensitivity compared to other assays.
What is autoimmune lymphoproliferative syndrome?
INTRODUCTION Autoimmune lymphoproliferative syndrome (ALPS) is characterized by dysregulation of the immune system due to an inability to regulate lymphocyte homeostasis through the process of lymphocyte apoptosis (a form of programmed cell death).
How is Schmidt's syndrome treated?
CLINICAL TREATMENT Treatment of primary hypothyroidism: physiologic thyroid hormone replacement with levothyroxine. Typical replacement dose is 1.6 mcg/kg per day (lower doses in elderly and those with cardiac disease) and adjusted every 4-6 weeks initially to maintain TSH and thyroxine levels in the mid normal range.
What causes Apeced?
APECED syndrome is caused by mutations in the gene AIRE. AIRE provides instructions for making a protein called the autoimmune regulator (AIRE), which helps control when other genes get “turned on,” or expressed. The AIRE protein is expressed in the thymus, a key immune organ located behind the breastbone.
What is Schmidt syndrome?
Schmidt syndrome also known as Polyglandular autoimmune syndrome type 2 is a rare autoimmune syndrome that commonly has the constellation of three diseases: diabetes mellitus type 1, hypothyroidism and adrenal insufficiency. Owing to the diabetes mellitus type 1, patients require life-long insulin therapy and blood glucose levels need to be monitored. They are at risk for chronic complications of diabetes such as neuropathy, nephropathy and retinopathy. More acutely, due to fluctuations in blood glucose levels, they are at risk for hypoglycemia with neuroglycopenic symptoms and ketoacidosis. Hypothyroidism is diagnosed by measuring the thyroid hormone levels and if inappropriately low is treated with replacement therapy. Patients with adrenal insufficiency experience symptoms due to low glucocorticoid and mineralocorticoid levels in the body, due to decreased or absent production.
What is autoimmune polyglandular syndrome?
Autoimmune polyglandular syndrome type 2 is an autoimmune disorder that affects many hormone-producing (endocrine) glands. [1] It is characterized by the presence of Addison’s disease along with autoimmune thyroid disease and/or type 1 diabetes. [1] Affected individuals may also have problems with other endocrine glands and other common features include primary hypogonadism, myasthenia gravis, and celiac disease. Autoimmune polyglandular syndrome type 2 is diagnosed in adulthood, typically around age 30. [2] The cause of autoimmune polyglandular syndrome type 2 is unknown, although it may involve a combination of genetic and environmental factors. This condition occurs more often in women than men. About 10% of patients with APS-2 and Addison’s disease had a relative with adrenal insufficiency, and about 10% of patients with APS-2 and type 1 diabetes had a sibling with the same disease, and, or with autoimmune thyroid disease. [1] [3]

Lithium carbonate wasn't helping ALS patients, and we learned it faster than the clinical trials did. Read about it in Nature .
What is the treatment for Schmidt syndrome?
Treatment for Schmidt Syndrome depends on the endocrine gland that is affected. The dysfunction of the pancreas requires insulin, adrenal dysfunction requires cortisol and thyroid dysfunction requires thyroid hormone replacement.
What is the treatment for acute Addison's disease?
Treatment of Acute Addison’s disease: higher doses of glucocorticoid therapy depending on the degree of physiological stress.
Is Schmidt syndrome hereditary?
Though a solid cause has not been determined, some clinical researchers believe that Schmidt Syndrome may be hereditary. If it is hereditary, it would involve a composite interaction among many genes.

When was Schmidt syndrome first reported?
In 1926, Schmidt M.B. described 2 patients with non-tuberculous Addison’s disease and thyroiditis, in both organs lymphocytic infiltration was found. Schmidt syndrome was initially reported as a biglandular disease. Later in 1964, Carpenter C.C. confirmed that T1DM was part of this syndrome. [14]
What is the difference between hyperthyroidism and hypothyroidism?
Diagnosis of primary hypothyroidism is based on: 1) an elevated serum TSH and low (or normal in subclinical disease) serum free T4 level , whereas hyperthyroidism is diagnosed based on a low TSH with elevated (or normal in subclinical disease) serum free T4 and/or total T3; and 2) the presence of antithyroid antibodies (e.g. anti-thyroid peroxidase (formerly anti-microsomal antibodies), anti-thyroglobulin antibodies, thyroid stimulating immunoglobulins) can be useful for confirming autoimmune etiology (see thyroid function tests module ).
How many patients with T1DM have Addison's disease?
Among patients with T1DM, < 1% of patients have Addison’s disease, whereas 2-5% have autoimmune thyroid disease (mainly hypothyroidism) and up to 5% have celiac disease. [12] Up to 33% may have thyroid autoantibodies and 12% have transglutaminase autoantibodies. [10]

What is Graves disease?
Grave’s disease: This is a disorder that affects the thyroid gland. It is thought to occur as a result of an imbalance in the immune system. This disorder causes increased thyroid secretion (hyperthyroidism), enlargement of the thyroid gland and protrusion of the eyeballs. The exact cause of this disorder is not known. It is thought to be inherited as an autosomal recessive trait. (For more information on this disorder choose “Graves Disease as your search term in the Rare Disease Database).
Why is failure of the endocrine glands accompanied by signs of malnutrition?
Failure of the endocrine glands to function is usually accompanied by signs of malnutrition because the ability of the intestinal tract to absorb nutrients is reduced dramatically. Since the combination of affected glands differs from patient to patient, the signs of this disorder are diverse.
What is the name of the condition that causes weakness and abnormally rapid fatigue of the voluntary muscles?
Myasthenia gravis is a chronic neuromuscular disease characterized by weakness and abnormally rapid fatigue of the voluntary muscles, with improvement following rest. Any group of muscles may be affected, but those around the eyes and the muscles used for swallowing are the most commonly involved.

What Is Schmidt Disease?
- Schmidt syndrome is a condition also sometimes referred to as PAS II or APS-2. It is not a term that refers to a single condition but rather considered a collective name for multiple autoimmune conditions. These conditions may co-occur in the patient’s body. The primary disease that forms part of Schmidt syndrome is autoimmune primary adrenal insuf...
Risk Factors
- Medical experts do not fully understand the precise cause of Schmidt syndrome. It is known that an autoimmune reaction is triggered. Various triggers may result in such a reaction. It has been suggested that a virus could cause an autoimmune reaction in some patients. Environmental antigens have also been suggested as potential triggers. In some studies, congenital rubella infe…
Symptomsof Schmidt Disease
- Symptoms can differ from one patient to another. This is because Schmidt’s disease can include different conditions. Primary adrenal deficiency concerning autoimmune activity is the main condition associated with Schmidt syndrome. Patients also develop autoimmune hypothyroidism or type 1 diabetes mellitus with this syndrome. In some patients, only two of these conditions wi…
Diagnosis
- Doctors have no specialty test used to diagnose Schmidt syndrome or the associated conditions, including APS-2. This makes the diagnosis process more difficult for the physician. The idea behind diagnosis is to identify the “component” disorders associated with APS-2 and Schmidt syndrome. By identifying these conditions’ presence, doctors have a better chance of providing a…
Treatment
- Treatment can only be provided once the patient has been diagnosed. The physician needs to understand all aspects of the patient’s condition, including the specific autoimmune conditionsaffecting their body. Individual treatments are usually prescribed for each of the autoimmune diseases identified during the diagnosis process. Levothyroxine will generally be us…
Conclusion
- Schmidt syndrome is a rare collection of autoimmune conditions. Adrenal sufficiency is the primary autoimmune condition that forms part of the syndrome. Additional autoimmune conditions also affect the patient when they are diagnosed with Schmidt syndrome. There are treatment options that may assist in reducing the symptoms. Some medicines may provide a re…
