Organic acidurias are inherited metabolic disorders causing organic acid buildup. This review details GC-MS diagnostic methods and updated reference values for classical organic acidurias, enhancing disease understanding.
Area of Science:
- Biochemistry
- Genetics
- Metabolic Disorders
Background:
- Organic acidurias are inherited metabolic diseases caused by enzyme or transport protein deficiencies.
- These deficiencies lead to the accumulation and urinary excretion of organic acids.
- Over 65 types exist, with a collective incidence of approximately 1 in 3000 live births.
Purpose of the Study:
- To review gas chromatography-mass spectrometry (GC-MS) methodologies for diagnosing classical organic acidurias.
- To provide updated reference values for common organic acids involved in these disorders.
- To present recent updates on the pathogenetic mechanisms of classical organic acidurias.
Main Methods:
- Focus on gas chromatography-mass spectrometry (GC-MS) based diagnostic techniques.
- Compilation and presentation of updated reference values for key organic acids.
- Literature review for recent pathogenetic insights.
Main Results:
- Established GC-MS as a primary diagnostic tool for classical organic acidurias.
- Provided current reference values for frequently implicated organic acids.
- Summarized recent advancements in understanding disease pathogenesis.
Conclusions:
- GC-MS is crucial for diagnosing classical organic acidurias.
- Updated reference values aid in accurate diagnosis and monitoring.
- Continued research into pathogenesis is vital for improved patient outcomes.

First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
