## TL;DR

This paper discusses a case of severe, treatment-resistant high ammonia levels in a 25-year-old and highlights the importance of removing ammonia from the blood.

## Contribution

The paper emphasizes the role of extracorporeal ammonia removal in managing refractory hyperammonemia.

## Key findings

- A 25-year-old patient had severe, treatment-resistant hyperammonemia.
- Extracorporeal elimination of ammonia was crucial in this case.
- Hereditary metabolic diseases should be considered in adults with hyperammonemia.

## Abstract

Die Hyperammonämie ist ein lebensbedrohliches Krankheitsbild, dessen Prognose von einer raschen Senkung des Ammoniaks abhängt. Ist eine hepatische Ursache ausgeschlossen, ist die Differenzialdiagnose breit und umfasst auch im Erwachsenenalter hereditäre Stoffwechselerkrankungen. Hier beschreiben wir den Fall einer 25-jährigen Patientin mit einer schweren, therapierefraktären Hyperammonämie und betonen die Relevanz der extrakorporalen Elimination des Ammoniaks.
