Background : Organic acid disorders are a heterogeneous group of inborn errors of metabolism, in which organic acids accumulate in the body.
They have high prevalence in Egypt because of a high rate of consanguineous marriages.
Here we report our experience with the diagnostic evaluation of patients with organic acidemias as well as several other inborn errors of metabolism (IEMs) by liquid chromatography–tandem mass spectrometry (LC / MS–MS), gas-chromatography mass spectrometry (GC / MS) and by isocratic cation exchange ‘‘high-performance liquid-chromatography’’ (HPLC) to evaluate the use of HPLC method for disease-associated metabolite screening.
Patients and methods : In this study, we screened 86 suspected Egyptians patients with organic acid disorders by LC / MS–MS, GC / MS and by HPLC aged from 3 days to 12 years old.
Data obtained from the three methods were statistically analyzed to evaluate the specificity and sensitivity of the HPLC method over the other two methods and to pursue its precision in the diagnosis of organic acid disorders.
Moreover, 17 urine samples were collected from patients with several other IEMs to evaluate the efficiency of HPLC in detecting abnormal metabolites in urine samples.
Results : The screening results showed that diagnostic efficiencies were varied among the three methods, HPLC showing a higher sensitivity of detecting normal urine as well as a highly satisfactory extent for the detection of different metabolic disorders.
In addition, some typical urinary HPLC chromatograms of different metabolic disorders were presented to help the investigator who is going to start an organic aciduria screening program by HPLC to be familiar with various patterns.
