A 91-year-old woman was brought to our hospital with altered consciousness. Blood tests showed an increased ammonia level of 468 μg/dL and a normal liver function. Chest computed tomography showed massive right pleural effusion with loculation. We immediately performed chest drainage using two drainage tubes. The pleural effusate pH was 8.5.

Longitudinal Changes in Glutamine and Ammonia in Relation to Hyperammonemic Crisis in Urea Cycle Disorders. [PDF]
ABSTRACT Hyperammonemic crisis (HAC) remains a major risk factor for urea cycle disorders (UCD), and practical outpatient predictors are limited. We tested whether short‐term changes in plasma glutamine (ΔGln) and ammonia (ΔNH3) predict HAC and whether effects differ by onset type. In a retrospective cohort (2014–2024) of 18 patients with UCD (neonatal‐

O-GlcNAcylation enhances CPS1 catalytic efficiency for ammonia and promotes ureagenesis
Hyperammonemia occurs in liver diseases affecting ureagenesis, and is life-threatening. Here, the authors show that liver UDP-GlcNAc is increased during hyperammonemia, leading to O-GlcNAcylation of the rate-limiting ureagenesis enzyme CPS1, that ...

A Newborn with Hypothermia and Hyperammonemia [PDF]
A full-term small gestational age female infant was transferred to the NICU for hypothermia and seizure-like activity. In the first 10 h of life, the infant had difficulty feeding and developed mild hypothermia, which resolved after placing her on a radiant warmer.

Hyperammonemia and proteostasis in cirrhosis [PDF]
Skeletal muscle loss or sarcopenia is a frequent complication of cirrhosis that adversely affects clinical outcomes. As skeletal muscle is the largest store of proteins in the body, proteostasis or protein homeostasis is required for maintenance of muscle mass. This review will focus on disordered skeletal muscle proteostasis in liver disease.Increased

Different types of hyperammonemia in clinical practice
Hyperammonemia is a metabolic disorder, which is caused as a result of high levels of ammonia present in the blood. Hyperammonemia is related to severe liver diseases, primarily to cirrhosis in 90% of cases.

Asthenia and fatigue in hyperammonemia: etiopathogenesis and methods of correction
Asthenia and fatigue are the most common syndromes in patients with liver disease, which significantly affects their quality of life. The prevalence of fatigue in chronic liver diseases is from 50% to 85%.

Pharmacologic rescue of hyperammonemia-induced toxicity in zebrafish by inhibition of ornithine aminotransferase. [PDF]
Hyperammonemia is the common biochemical hallmark of urea cycle disorders, activating neurotoxic pathways. If untreated, affected individuals have a high risk of irreversible brain damage and mortality.
