99 Possible Causes for Hyperammonemia, Respiratory Alkalosis

  • Acute Liver Failure

    Metabolic: Metabolic and respiratory alkalosis may occur early. If shock develops, metabolic acidosis can supervene.[merckmanuals.com] During the first 2 years of her life, a series of infections with episodes of fever were accompanied by elevated liver enzyme levels, but hyperammonemia, hypoglycemia, coagulopathy[ncbi.nlm.nih.gov] Continuous renal replacement therapy can help mitigate acid-base and metabolic derangements and control hyperammonemia.[pulmccm.org]

  • Urea Cycle Disorder

    […] distress * Respiratory alkalosis * Increased blood ammonia level * Failure to thrive * Constant infant crying * Agitation * Hyperactive behavior * Self-injury * Screaming[checkorphan.org] It is not indicated for treatment of hyperammonemia.[emedicine.medscape.com] Soon after, seizures, hypotonia (poor muscle tone, floppiness), respiratory distress (respiratory alkalosis), and coma may occur.[nucdf.org]

  • Propionic Acidemia

    While hyperventilation may provoke respiratory alkalosis, most patients present with metabolic acidosis due to further metabolic disturbances.[symptoma.com] The patient's hyperammonemia was monitored for 1 week.[ncbi.nlm.nih.gov] Alkalosis Urea cycle disorders Metabolic Profiles Organic and Amino Acid Disorders Metabolic Profiles Organic and Amino Acid Disorders Newborn screening is available dependent[vdocuments.mx]

  • Reye Syndrome

    Signs of metabolic derangement include elevated serum amino acid levels, acid-base disturbances (usually with hyperventilation, mixed respiratory alkalosis–metabolic acidosis[merckmanuals.com] Patients may brought in to the emergency room in seizure due to hyperammonemia and brain edema.[symptoma.com] An initial metabolic acidosis is associated with a compensatory respiratory alkalosis (1,3). The EEG shows diffuse arrhythmic delta activity (1).[hawaii.edu]

  • Carbamoyl Phosphate Synthetase Deficiency

    Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, neonatal hypotonia; respiratory alkalosis; hyperammonemia; coma, and death[icd9data.com] Hyperammonemia type 3 is a pathogenetically different but clinically similar UCD provoked by NAGS deficiency.[symptoma.com] Initial laboratory findings will include respiratory alkalosis which is the earliest objective indication of encephalopathy.[themedicalbiochemistrypage.org]

  • Ornithine Transcarbamylase Deficiency

    Respiratory alkalosis was regularly observed; the mean pH and pCO2 were 7.5 and 24 torr, respectively.[ncbi.nlm.nih.gov] In cases with neonatal onset of hyperammonemia, similar lesions have also been reported.[ncbi.nlm.nih.gov] Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, neonatal hypotonia; respiratory alkalosis; hyperammonemia; coma, and death[icd9data.com]

  • Hepatic Encephalopathy

    Laboratory abnormalities in hepatic encephalopathy: Blood tests may show abnormal liver chemistry tests, increased blood ammonia level, respiratory alkalosis with central[enotes.tripod.com] Abstract Splenorenal shunts are a rare cause of hyperammonemia and hepatic encephalopathy in the absence of cirrhosis.[ncbi.nlm.nih.gov] Although the true mechanism of hyperammonemia in this case is unclear, we speculate that organic constipation following chronic obstruction of the colon might have played[ncbi.nlm.nih.gov]

  • Hyperammonemia

    Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, neonatal hypotonia; respiratory alkalosis; hyperammonemia; coma, and death[icd9data.com] Online Mendelian Inheritance in Man (OMIM) 237310 - hyperammonemia due to N-acetylglutamate synthetase deficiency Online Mendelian Inheritance in Man (OMIM) 237300 - hyperammonemia[en.wikipedia.org] Respiratory alkalosis is common due to central hyperventilation. Severe hyperammonemia can also cause seizures.[renalfellow.blogspot.com]

  • Hyperornithinemia-Hyperammonemia-Homocitrullinuria Syndrome

    The neonatal presentation usually begins a few days after birth with lethargy, somnolence, refusal to feed, vomiting, tachypnea with respiratory alkalosis, and/or seizures[orpha.net] Therefore, ornithine loading did not protect this hyperornithinemia-hyperammonemia-homocitrullinuria patient from hyperammonemia induced by amino-nitrogen loading.[ncbi.nlm.nih.gov] Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, neonatal hypotonia; respiratory alkalosis; hyperammonemia; coma, and death[icd9data.com]

  • Liver Failure

    alkalosis Hypomagnesemia Hypophosphatemia Hyponatremia Hypokalemia Back to Top Treatment The foundation of therapy for ALD is abstinence.[clevelandclinicmeded.com] Briefly, hyperammonemia may be involved in the development of cerebral edema. Brain edema is thought to be both cytotoxic and vasogenic in origin.[emedicine.com] L; AST/ALT ratio 2:1 Hematologic Anemia Leukocytosis or leukopenia Thrombocytopenia Increased serum globulin levels Metabolic Elevated blood ammonia level Hyperglycemia Respiratory[clevelandclinicmeded.com]
