Propionic and methylmalonic acidemias (PAcidemia and MMAcidemia, respectively) are genetic disorders characterized by acute metabolic decompensation and neurological complications. L-carnitine (LC) is effective in reducing toxic metabolites that are related to the pathophysiology of these diseases. Therefore we investigated biomarkers of inflammation (cytokines and C-reactive protein (CRP)), neurodegeneration (BDNF, NCAM-1 and cathepsin-D) and biomolecules oxidation (sulfhydryl content and thiobarbituric acid-reactive species (TBARS)), as well as carnitine concentrations in untreated patients with PAcidemia and MMAcidemia, in patients under treatment with LC and a protein-restricted diet for until 2 years and in patients under the same treatment for more than 2 years.

- Propionic and methylmalonic acidemias are serious genetic disorders in newborns that cause dangerous metabolic crises, necessitating swift treatment for survival.
- A study found that a low-protein diet paired with L-carnitine supplements can reduce the harmful effects and risks associated with these conditions by lowering toxic metabolite levels.
- Long-term treatment with this diet and supplements showed promising results in reducing markers of oxidative damage in patients, suggesting potential protective effects against further complications, although more research is needed to link oxidative stress directly to patient health outcomes.
Urea cycle disorders (UCD) are a group of genetic diseases caused by deficiencies in the enzymes and transporters involved in the urea cycle. The impairment of the cycle results in ammonia accumulation, leading to neurological dysfunctions and poor outcomes to affected patients. The aim of this study is to investigate and describe UCD patients' principal clinical and biochemical presentations to support professionals on urgent diagnosis and quick management, aiming better outcomes for patients.

In this study, we report 24 symptomatic GA-1 Brazilian patients, and present their clinical, biochemical, and molecular findings. Patients were diagnosed by high levels of glutaric and/or 3-hydroxyglutaric and glutarylcarnitine.
