Insights
Diagnosing inborn errors of metabolism (IEM) is challenging. This study analyzed pediatric intensive care unit (PICU) data, finding consanguinity in 50% of confirmed small molecule disorder cases.
Area of Science:
- Biochemistry
- Pediatrics
- Genetics
Background:
- Inborn errors of metabolism (IEM) collectively cause significant morbidity and mortality.
- Diagnosis of IEM is often challenging due to their rarity and diverse presentations.
Purpose of the Study:
- To analyze epidemiological and clinical data of patients with suspected small molecule disorders admitted to a pediatric intensive care unit (PICU).
- To determine the diagnostic yield and clinical outcomes for these patients.
Main Methods:
- Retrospective analysis of medical records for patients admitted to Alexandria University Children's Hospital PICU between January 2010 and December 2014.
- Inclusion criteria: suspected or confirmed diagnosis of small molecule disorders.
Main Results:
- 34 patients had suspected or confirmed small molecule disorders.
- Diagnosis was confirmed in 22.7% at admission and 25% during PICU stay.
- Consanguineous marriage was present in 50% of confirmed cases.
Conclusions:
- A high index of suspicion is crucial for diagnosing small molecule disorders.
- Screening high-risk individuals in low- and middle-income countries is important.
Background:
Although inborn errors of metabolism (IEM) are rare individually, collectively IEM cause substantial morbidity and mortality and the diagnosis is challenging.
Aims:
To analyse epidemiological and clinical data, final diagnosis and clinical outcomes of patients with a suspected diagnosis of IEM (small molecule disorders type) admitted to a paediatric intensive care unit (PICU).
Methods:
We collected and analysed medical records data of all patients admitted to the PICU at Alexandria University Children's Hospital, from January 2010 to December 2014, with a suspected or confirmed diagnosis of small molecule disorders, including clinical presentations, laboratory results and clinical outcomes.
Results:
A total of 34 patients had a suspected or confirmed diagnosis of small molecule disorders at PICU admission. Diagnosis was confirmed in 22.7% of suspected cases at admission and in 25% of suspected cases during PICU stay. Consanguineous marriage was found in 50% of cases with confirmed small molecule disorders.
Conclusions:
A high index of suspicion is important for diagnosing and categorizing small molecule disorders in screening of high-risk individuals in low- and middle-income countries.
