425 Possible Causes for Ammonia Increased

  • Alcoholic Liver Disease

    The main factor involved in causing the encephalopathy is an increase in ammonia levels in the brain.[] Examples include: Hepatic encephalopathy: Increased ammonia levels due to the liver's inability to process and metabolize proteins in the diet can cause confusion, lethargy[] […] estradiol; impotence (erectile dysfunction, ED), poor sex drive and shrinking testicles are due to decrease in function of sex hormones; confusion and lethargy may occur if ammonia[]

  • Toxic Liver Disease

    Abnormal cell function in the liver means ammonia levels increase in the blood.[] High amounts of ammonia affect the brain resulting in confusion, brain damage, coma and can cause death.[] According to the National Institutes of Health, the normal range of ammonia in the blood is between 15 and 45mcg/dL.[]

  • Hyperammonemia Type 3

    As has been indicated above, the central nervous system is most sensitive to increased concentrations of ammonia.[] Ammonia levels may be factitiously increased if the tourniquet is too tight for a long period.[] Hyperammonemia Treatment The treatment of Hyperammonemia aims at restricting the intake of ammonia as well as increasing its excretion.[]

  • Hyperornithinemia-Hyperammonemia-Homocitrullinuria Syndrome

    Blood ammonia increased from high normal values to 975, 990, and 750 mumol/liter (normal less than 70) and urinary orotic acid from trace to 539, 494, and 1296 mumol/mmol[] Increased levels of ammonia, ornithine and homocitrulline were demonstrated in blood and cerebrospinal fluid.[] While ammonia in plasma was not increased the supply of citrulline or arginine led to a reduction of plasma glutamine compared to ornithine supplement or to no supplement[]

  • Propionic Acidemia

    OBJECTIVES: The objective of this study was to determine whether N-carbamylglutamate (NCG) reduces plasma levels of ammonia and glutamine and increases the rate of ureagenesis[] increasing, rather than decreasing with increasing ammonia levels.[] Supplementation of branched-chain amino acids, isoleucine (5mM) and valine (5mM) in the medium, resulted in increased ammonia and decreased urea in the PA patient hepatocyte[]

  • Carbamoyl Phosphate Synthetase Deficiency

    They may rapidly progress to respiratory alkalosis as ammonia increases with cerebral edema, seizures, loss of reflexes, hypothermia, apnea, and coma.[] Biochemically, a highly elevated blood ammonia level was found together with an increased plasma level of the amino acids mainly involved in ammonia detoxication.[] The central nervous system is most sensitive to increased levels of ammonia and patients suffering from CPSI deficiency thus present with hyperammonemic encephalopathy.[]

  • Urea Cycle Disorder

    An increased level of ammonia in the bloodstream, or hyperammonemia, is a symptom associated with metabolic disorders referred to as inborn errors of metabolism.[] […] blood ammonia level * Failure to thrive * Constant infant crying * Agitation * Hyperactive behavior * Self-injury * Screaming * Dislike of eating meat * Dislike of eating[] Hyper ammonemia occurs as a result of increased levels of ammonia and once this toxic substance reaches the brain, it can cause irreversible impairment, coma or even death[]

  • Isovaleric Acidemia

    […] intracranial pressure attention to “sweaty foot” body odor Labs Blood – venous blood gas for blood pH – electrolytes, measured CO2, glucose – blood ammonia (**draw WITHOUT[] Symptoms are triggered by any minor illness; protein diet results in increased levels of isovaleric acid.[] […] levels of acidic substances in the blood, called metabolic acidosis high levels of ammonia in the blood ketones in the urine low platelets low level of white blood cells[]

  • Common Cold

    After logistic-regression analysis, however, an age of less than five years and a serum ammonia level above 45 μg per deciliter remained significantly associated with an increased[] […] of alanine aminotransferase, aspartate aminotransferase, or ammonia in serum.[] The encephalopathy must be associated with either fatty metamorphosis of the liver, diagnosed by biopsy or at autopsy, or a tripling (or a greater increase) in the levels[]

  • Hyperammonemia

    BACKGROUND & AIMS: Increased skeletal muscle ammonia uptake with loss of muscle mass adversely affects clinical outcomes in cirrhosis.[] Various therapies, including those to decrease ammonia generation, increase nitrogen excretion, and several dialytic methods for removing ammonia have been tried.[] Despite the administration of a lactulose enema, the patient's serum ammonia level increased and he remained confused, leading us to initiate acute hemodialysis.[]
