Performance Evaluation of Dry Chemical Colorimetry for Plasma Ammonia Detection on the VITROS 350 Chemistry System

Journal of Clinical Laboratory Analysis, EarlyView.
This study comprehensively validates the analytical performance of the VITROS dry chemical colorimetric assay for plasma ammonia on the VITROS 350 system. The assay shows excellent precision, accuracy, and linearity throughout the analytical range. It is highly resistant to common interferents such as bilirubin, lipids, and vitamin K1.

Diverting the Diagnosis: A Case Report of Hemodialysis Masking the Etiology of Hyperammonemia

Canadian Journal of Kidney Health and Disease
Rationale: Hyperammonemia in patients receiving hemodialysis is uncommon but poses a significant clinical challenge due to the effective clearance of ammonia by dialysis, which can obscure the underlying cause.

Brain Aquaporin 4 in Hyperammonemia [PDF]

, 2010
In liver failure, congenital enzymopathies of the urea cycle, and other disorders, ammonia may not be properly detoxified and thus hyperammonemia ensues.

Hyperammonemia in a carbamoyl-phosphate synthetase 1 deficiency recipient after living-donor liver transplantation from a carrier donor: a case report

Frontiers in Medicine
Carbamoyl-phosphate synthetase 1 (CPS1) deficiency is an autosomal recessive congenital urea cycle disorder (UCD) characterized by hyperammonemia. The recipients of liver transplantation (LT) for UCD are often children, and the potential donors are often

Ureaplasma urealyticum infection presenting as altered mental status in a post-chemotherapy patient: Case report and literature review

Frontiers in Medicine, 2022
Hyperammonemia due to Ureaplasma infection is rare but often fatal, largely due to the delayed recognition, diagnosis, and treatment of the condition. It has mostly been described in solid organ transplant patients in the literature.

Prognostic Role of Ammonia in Critical Care Patients Without Known Hepatic Disease

Frontiers in Medicine, 2020
Background and Aims: Hyperammonemia usually develops because of hepatic disease, but it may occur in patients with non-hepatic hyperammonemia (NHH). But, studies on the prognosis and possible risk factors of this disorder are lacking.

Renal replacement therapy in neonates with an inborn error of metabolism [PDF]

Korean Journal of Pediatrics, 2019
Hyperammonemia can be caused by several genetic inborn errors of metabolism including urea cycle defects, organic acidemias, fatty acid oxidation defects, and certain disorders of amino acid metabolism.

Patient iPSC‐derived astrocytes reveal impaired homeostasis and reactive‐like features in propionic acidemia

The Journal of Pathology, EarlyView.
Abstract Propionic acidemia (PA) is a neurometabolic disorder caused by propionyl‐CoA carboxylase deficiency with frequent neurological involvement, yet cell‐type‐specific mechanisms remain poorly defined. We established human induced pluripotent stem cell (iPSC)‐derived astrocytes (iAs) from patients harboring PCCA or PCCB mutations and investigated ...
