Interchangeability between 24-hour collection and single spot urines for vanillylmandelic and homovanillic acid levels in the diagnosis of neuroblastoma.[Pubmed:23813598]
Pediatr Blood Cancer. 2013 Dec;60(12):E170-2.
The determination of the two urinary catecholamine metabolites Homovanillic acid (HVA) and vanillylmandelic acid (VMA) is of crucial importance for the diagnosis and follow-up of neuroblastoma (NB). The standard practice for their measurement requires the use of 24-hour collections that are time consuming and difficult to obtain. In this article, we directly demonstrate that 24-hour collections and single spot urines are interchangeable for the determination of HVA and VMA expressed as ratio on creatinine concentration. This study can be useful for a faster management of NB at onset.
Analysis of vanillylmandelic acid and homovanillic acid by UPLC-MS/MS in serum for diagnostic testing for neuroblastoma.[Pubmed:23830883]
Clin Chim Acta. 2013 Sep 23;424:253-7.
BACKGROUND: Vanillylmandelic acid (VMA) and Homovanillic acid (HVA) are typically measured in urine for the diagnosis and monitoring of neuroblastoma, a tumor in children <5 y. A protocol for evaluation of serum VMA and HVA has been utilized at our institution for approximately 25 y, originally validated using high performance liquid chromatography (HPLC) with an electrochemical detector. We recently validated a serum VMA/HVA method by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). METHODS: After solvent extraction and clean up with Ultrafree centrifugal filters, samples were analyzed by UPLC-MS/MS in multiple reaction monitoring mode. RESULTS: The assay was linear between 2 and 1000 ng/ml for VMA and HVA. Within run and run to run CVs were <5% for VMA at all levels, <10% for HVA at high levels, and <20% at low levels. Correlation with the HPLC method was acceptable with a constant bias. The reference interval for VMA by UPLC-MS/MS was determined to be 80% for both VMA and HVA. CONCLUSION: Correlation of VMA and HVA was acceptable after adjustment of reference intervals. Collection of a single serum sample instead of 24-h urine collection saves time and improves accuracy of measurement due to difficulty of collecting a 24-h urine sample in infants and young children. UPLC-MS/MS also offers improved analyte specificity, improved signal to noise, and rapid analysis time.
Homovanillic acid in cerebrospinal fluid of 1388 children with neurological disorders.[Pubmed:23480488]
Dev Med Child Neurol. 2013 Jun;55(6):559-66.
AIM: To determine the prevalence of dopaminergic abnormalities in 1388 children with neurological disorders, and to analyse their clinical, neuroradiological, and electrophysiological characteristics. METHOD: We studied biogenic amines in 1388 cerebrospinal fluid (CSF) samples from children with neurological disorders (mean age 3y 10mo, SD 4y 5mo; 712 males, 676 females. Correlations among CSF Homovanillic acid (HVA) values and other biochemical, clinical, neuroradiological, and electrophysiological parameters were analysed. RESULTS: Twenty-one patients with primary dopaminergic deficiencies were identified. Of the whole sample, 20% showed altered HVA. We report neurological diseases with abnormal CSF HVA values such as pontocerebellar hypoplasia, perinatal asphyxia, central nervous system infections, mitochondrial disorders, and other genetic diseases. Overlapping HVA levels between primary and secondary dopamine deficiencies were observed. Prevalence of low CSF HVA levels was significantly higher in neonatal patients (chi(2) =84.8, p<0.001). Abnormalities in white matter were associated with low CSF HVA (odds ratio 2.3, 95% confidence interval 1.5-3.5). INTERPRETATION: HVA abnormalities are observed in various neurological diseases, but some are probably an unspecific finding. No clear limits for CSF HVA values pointing towards primary diseases can be stated. We report several neurological diseases showing HVA alterations. No neuroimaging traits were associated with low HVA values, except for white matter abnormalities.
Molecular structure and spectroscopic analysis of homovanillic acid and its sodium salt--NMR, FT-IR and DFT studies.[Pubmed:24161870]
Spectrochim Acta A Mol Biomol Spectrosc. 2014 Jan 24;118:1068-74.
The estimation of the electronic charge distribution in metal complex or salt allows to predict what kind of deformation of the electronic system of ligand would undergo during complexation. It also permits to make more precise interpretation of mechanism by which metals affect the biochemical properties of ligands. Theinfluence ofsodium cation on the electronic system of Homovanillic acid was studied in this paper. Optimized geometrical structures of studied compounds were calculated by B3LYP/6-311++G(**) method. Mulliken, MK and ChelpG atomic charges were analyzed. The theoretical NMR and IR spectra were obtained. (1)H and (13)C NMR as well as FT-IR and FT-Raman spectra of studied compounds were also recorded and analyzed. The calculated parameters are compared with experimental characteristics of these molecules.
