What is mitochondrial disease and how is it treated?
What are the treatment options for mitochondrial disorders? Currently, vitamins and supplements are the mainstay of treatment for mitochondrial disorders. They are thought to help mitochondria produce energy and reduce accumulation of toxic compounds inside cells. These supplements and cofactors are sometimes given together in “cocktails.”
Is there cure for mitochondrial diseases?
Treatment for mitochondrial disease. Currently there is no highly effective treatment or cure for mitochondrial disorder. The management of mitochondrial disease is supportive therapy, which may include nutritional management, exercise and/or vitamin or amino acid supplements.
How might mitochondrial disease affect my lifespan?
The researchers indicated that boosting the immune system of children with mitochondrial disease may be key to increasing their lifespan. A similar small study of 30 adult patients with mitochondrial disease demonstrated that the main cause of death was respiratory failure, heart failure, and cerebral incidents such as seizures or strokes. However, in nearly half of the patients, the cause of death was unknown.

A small study in children with mitochondrial disease examined the patient records of 221 children with mitochondrial disease. Of these, 14% died three to nine years after diagnosis. Five patients lived less than three years, and three patients lived longer than nine years.
Are all mitochondrial disease treatable?
There are no cures for mitochondrial diseases, but treatment can help reduce symptoms or slow the decline in health. Treatment varies from patient to patient and depends on the specific mitochondrial disease diagnosed and its severity.
How serious is mitochondrial disease?
The parts of the body that tend to be most affected are those that need the most energy, such as the heart, brain, muscles and gastrointestinal tract. Symptoms can range from fatigue and exercise intolerance to hearing loss, seizures, strokes, heart failure, diabetes and kidney failure.
What is the most common mitochondrial disease?
Together, Leigh syndrome and MELAS are the most common mitochondrial myopathies. The prognosis of Leigh syndrome is generally poor, with survival generally being a matter of months after disease onset.
Can you recover from mitochondrial disease?
Currently there is no highly effective treatment or cure for mitochondrial disorder. The management of mitochondrial disease is supportive therapy, which may include nutritional management, exercise and/or vitamin or amino acid supplements.
Is mitochondrial disease a terminal illness?
Mitochondrial disease (mito) is a debilitating and potentially fatal disease that reduces the ability of the mitochondria to produce this energy. When the mitochondria are not working properly, cells begin to die until eventually whole organ systems fail and the patient's life itself is compromised.
What can trigger mitochondrial disease?
Mitochondrial diseases are not contagious, and they are not caused by anything a person does. They're caused by mutations, or changes, in genes — the cells' blueprints for making proteins.
When should you suspect mitochondrial disease?
Although it is not specific, an unexplained elevation of lactate in any tissue (blood, cerebrospinal fluid, brain, or urine) should raise suspicions for a mitochondrial disorder and warrants evaluation, whereas a normal lactate level in any or all tissues does not eliminate the possibility of a mitochondrial disorder.
Why are Mitochondrial diseases only inherited from the mother?
An individual's mitochondrial genome is entirely derived from the mother because sperm contain relatively few mitochondria, and these are degradated after fertilization.
How is mitochondrial disease diagnosed?
Genetic testing is essential for the diagnosis of mitochondrial diseases. Next generation sequencing with gene dosage of nDNA and mtDNA in blood or affected tissues (muscle, buccal swab, urine sediment, liver biopsy) is recommended over testing for specific point mutations in cases of suspected mitochondrial disease.
Is lupus a mitochondrial disease?
They found that a large number of lupus patients had red blood cells with detectable levels of mitochondria—and these cells were especially frequent in patients with the most severe lupus symptoms. By contrast, healthy controls had no mitochondria-containing red blood cells.
Is there a blood test for mitochondria?
A mitochondrial antibody test is used to determine the presence of mitochondrial antibodies which can be used in conjunction with clinical findings and other laboratory tests to aid in the diagnosis of primary biliary cirrhosis (PBC).
Why do mitochondrial diseases become more severe?
Mitochondrial patients may become ill more quickly and more severely than other people because of a lower cellular reserve of energy. Cellular stresses, such as illness, fatigue, or poor nutrition, may lead to cell injury ...
What is the best vitamin for intercurrent illness?
Vitamin C – for intercurrent illness supplement. Diet therapy, as prescribed by your doctor along with a registered dietitian, may be recommended. Important: A physician should always guide specific treatments. Patients should not take any supplements or try any treatment unless prescribed by a doctor.
What supplements are used for CSF deficiency?
Arginine – for stroke-like events. Folinic acid – only routine for documented CSF deficiencies and diseases known to cause deficiency and considered with central nervous system manifestations. L-carnitine – for carnitine deficient patients only. Vitamin C – for intercurrent illness supplement.
Can mitochondrial disease cause exercise intolerance?
Exercise intolerance is common with mitochondrial disease, but even patients who have a difficult time exercising should still be encouraged to exercise beginning at their current level of function. Patients should consult their physician before beginning to exercise as cardiac or other evaluations may be needed.
Is Mitochondrial Disease a biochemical disease?
Mitochondrial Disease Treatment. Physicians specializing in metabolic diseases have found that every child and adult is biochemically different, meaning that no two people will respond to a particular treatment in a specific way, even if they have the same disease.
Does running help with mitochondrial disease?
Research has shown that both endurance (such as running) and resistance (such as weight lifting) exercise can benefit patients with mitochondrial disease. Some benefits include an increase in mitochondrial health, antioxidant and muscle mitochondrial enzyme activity, oxygen uptake, and muscle strength, as well as improved clinical symptoms ...
Why do mitochondrial diseases get worse?
Therefore, treatment is individualized for each patient and type of mitochondrial disease. Mitochondrial patients may become ill more quickly and more severely than other people because of a lower cellular reserve of energy. Cellular stresses, such as illness, fatigue, or poor nutrition, may lead to cell injury and associated worsening ...

What are the symptoms of a symtom?
The symptoms you have depends on which cells and organs are affected, these may include: Other symptoms include gastrointestinal disorders, difficulty swallowing, cardiac disease, liver disease, diabetes, lactic acidosis, and an increased likelihood of getting infections.
Why is mitochondrial disease so difficult to diagnose?
Mitochondrial disease can be difficult to diagnose because the disease can present with a wide variety of symptoms, ranging from mild to severe. There are hundreds of different types of mitochondrial diseases.
What are the diseases that are linked to mitochondrial dysfunction?
Researchers are studying mitochondrial disease for clues to other conditions such as cancer, Parkinson’s disease, Alzheimer’s disease, and heart disease. Damage to the mitochondria is thought to be associated with all of those conditions.
How to reduce mitochondrial disease symptoms?
Avoiding stress may also help reduce symptoms. Researchers are currently looking into drugs that would block the lactic acid buildup associated with mitochondrial disease. Others are trying very low carbohydrate diets to reduce the mitochondria’s workload.
How many people have mitochondrial disease?
Mitochondrial disease affects between 40,000 and 70,000 Americans, occurring in one in 2,500 to 4,000 births. Mitochondrial disease is a genetic condition. The disease can either be inherited from your parents or the result of a random mutation in your DNA.
What is the part of the body that produces energy?
Updated on January 05, 2020. Inside body cells are tiny little parts called mitochondria (as many as 1,000 per cell). Mitochondria produce the energy our cells need to grow and function. If the mitochondria are damaged or malfunctioning, the cells cannot carry out their functions and can become injured or die.
What organs are affected by mitochondria?
Signs and Symptoms. Because mitochondria are present in 90% of our cells, a variety of organs can be affected including the brain and muscles. The most affected systems are typically the brain, heart, liver, skeletal muscles, kidney, and endocrine and respiratory systems.
What is the DNA of the mitochondria?
Mitochondria are unique in that they have their own DNA called mitochondrial DNA, or mtDNA. Mutations in this mtDNA or mutations in nuclear DNA (DNA found in the nucleus of a cell) can cause mitochondrial disorder. Environmental toxins can also trigger mitochondrial disease.
What happens when mitochondria are disrupted?
When the number or function of mitochondria in the cell are disrupted, less energy is produced and organ dysfunction results. Depending on which cells within the body have disrupted mitochondria, different symptoms may occur. Mitochondrial disease can cause a vast array of health concerns, including fatigue, weakness, metabolic strokes, seizures, ...
