About pyroglutamicaciduria

What is pyroglutamicaciduria?

5-Oxoprolinuria is a biochemical finding that can arise from two underlying metabolic disorders. It is characterized by excretion of massive amounts of the chemical 5-oxoproline.

What are the symptoms for pyroglutamicaciduria?

Pyroglutamicaciduria (PGA) is a rare metabolic disorder that causes high levels of PGA in the blood.

  • Pyroglutamic acid (PA) is an intermediate product of glutamine metabolism.
  • Glutamine is a non-essential amino acid that is abundant in the body and is involved in many metabolic processes.
  • PA is formed from glutamine via transamination reactions involving glutamate dehydrogenase (GDH).
  • PA is excreted in urine and is present at high concentrations in patients with glutaminuria.
  • Patients have variable clinical presentations ranging from mild hyperammonemia to severe neurological manifestations including Seizures, developmental delay, hypotonia, and coma.
  • Though there is no specific treatment for pyroglutamateuria.
  • Doctors suggest antibiotics, avoiding foods that cause Diarrhea and dietary protein restriction.
  • If left untreated, it can cause severe damage to the brain and nervous system.
  • Symptoms often begin between infancy and childhood and may include Fatigue, loss of appetite, Nausea, Vomiting, jaundice (yellowing of the skin), dark-colored urine, Headaches, Seizures, difficulty breathing, Irritability, Lethargy, Weight loss, muscle Weakness, Fever, Weakness, Abdominal pain, and Diarrhea.
  • A blood test will show high levels of PGA in the urine.

What are the causes for pyroglutamicaciduria?

Pyroglutamic acid (PA) is a naturally occurring substance that is produced in the human body. It is found in the urine and is excreted via the kidneys. Pyroglutamic acid is basically a metabolic product of glutamine.

  • Glutamine is an amino acid that is produced by the body's cells. pyroglutamicaciduria (PGA) is excreted in urine when these amino acids become elevated in the blood.
  • Pyroglutamicaciduria acids are formed when glutamine is broken down by bacteria in the intestine.
  • These metabolites are then passed out as urine.
  • Pyroglutamate is not toxic to humans; however, if high levels of it accumulate in the bloodstream, it can cause lactic acidosis and kidney failure. The cause of PGA accumulation is unknown.
  • It is believed that PGA is formed due to a defect in the enzyme glutamate dehydrogenase (GDH), which converts L-glutamate into α-ketoglutarate.
  • Mutations in GDH have been associated with PGA accumulation.
  • Urinary PA levels are often measured through urine analysis to determine if a person is affected or not.
  • Symptoms of PGA accumulation vary depending on the severity of the condition.
  • Mild forms of PGA accumulation may not affect the individual's daily activities.
  • However, severe cases of PGA accumulation can lead to neurological disorders and even death.
  • There is no known cure for PGA, although treatment focuses on reducing the production of pyroglutamates

What are the treatments for pyroglutamicaciduria?

Glutathione synthetase deficiency, also known as pyroglutamicaciduria, is an extremely rare condition or disorder. It is characterized by a deficiency of the enzyme glutathione synthetase, a part of the chemical process by which the body creates glutathione. This protein molecule plays a role in many cell processes.

  • Diagnosing pyroglutamicaciduria is based upon identifying characteristic findings, a detailed patient and family history, and a variety of specialized tests.
  • The treatment of pyroglutamicaciduria is to reduce the symptoms that are apparent in each individual. Sodium bicarbonate is used to correct metabolic acidosis.
  • Initially, this may require parenteral (e.g. intravenous) therapy.
  • Later, the affected individuals will be given sodium bicarbonate or citrate, orally.
  • Vitamins E and C supplements, which have antioxidant properties, may also be given.
  • Drugs that precipitate hemolysis in glucose-6-phosphate dehydrogenase deficiency should be avoided.
  • Genetic counseling should be offered to affected individuals and their families.

What are the risk factors for pyroglutamicaciduria?

Glutathione synthetase deficiency, also known as pyroglutamicaciduria, is an extremely rare condition or disorder. It is characterized by a deficiency of the enzyme glutathione synthetase, a part of the chemical process by which the body creates glutathione. This protein molecule plays a role in many cell processes.

Risk factors:

  • Pyroglutamicaciduria is caused by alterations in the GSS gene. GSS genes play a critical role in many functions of the body.
  • When a mutation of a gene occurs, it results in a faulty, inefficient, or absent protein product.
  • Depending upon the functions of the particular protein, this can affect many body organ systems, including the brain.
  • The GSS gene contains instructions for making the enzyme glutathione synthetase that is required for the body to create the small protein molecule glutathione.
  • An alteration in the GSS gene causes deficiency of glutathione synthetase, leading to a lack of glutathione, a peptide molecule that plays a crucial role in many cellular processes.
  • Cellular processes are activities inside a cell that is vital for proper health and development.
  • As per research, it is believed, that certain genetic and environmental factors, in addition to alterations in the GSS gene, influence the severity of glutathione synthetase deficiency.
  • Modifier genes, unlike the GSS gene, affect the clinical severity of the disorder.

Is there a cure/medications for pyroglutamicaciduria?

There is no cure for GSD/pyroglutamicaciduria. Treatment is restricted to managing symptoms and associated problems. Sodium bicarbonate is recommended to treat metabolic acidosis, and antioxidants, among them vitamins E and C, can reduce oxidative damage
