HPLC-MS/MS method for simultaneous analysis of plasma 2-hydroxybutyrate and 2-hydroxyisobutyrate: Development and clinical significance
Recent studies have identified relationships between diabetes mellitus and short-chain fatty acids, including 2-hydroxybutyrate (2-HB) and 2-hydroxyisobutyrate (2-HiB); 2-HB has been associated to the early stages of insulin resistance, while 2-HiB with the risk and progression of complications of Type 1 diabetes. Their metabolism and pathophysiological role in humans are not fully clarified.
The possible association between 2-HB and 2-HiB and diabetes mellitus was investigated with a novel mass spectrometry-based assay, capable of discriminating plasma 2-HiB and 2-HB from their HB isomers. Accuracy and precision (RSD%) were always in the range 99–102% and 0.7–3.5%, respectively. The study involved samples from subjects with normal glucose tolerance (NGT) and Type 2 diabetes (T2D), originally included in a multicenter study investigating mechanisms involved in atherothrombosis.
NGT subjects exhibited concentrations of 2-HB and 2-HiB of 61 (36) and 3.1 (1.9) µmol/L, median (interquartile range), respectively, that were significantly lower than those of the T2D patients, whose values were 74 (4.0) and 3.8 (2.9) µmol/L, respectively. The pattern of association of these molecules with clinical and metabolic variables is partially different: both compounds were directly related to male sex, BMI, HbA1c, and plasma glucose, 2-HiB also with age, systolic blood pressure, and HDL-cholesterol. Furthermore, they correlate with free fatty acids, glycerol, and triglyceride concentrations, but the latter correlation was negative for 2-HB and positive for 2-HiB.
Results confirmed the clinical significance of 2-HB and 2-HiB, in differential association with metabolic features of T2D.
期刊介绍:
The Official Journal of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC)
Clinica Chimica Acta is a high-quality journal which publishes original Research Communications in the field of clinical chemistry and laboratory medicine, defined as the diagnostic application of chemistry, biochemistry, immunochemistry, biochemical aspects of hematology, toxicology, and molecular biology to the study of human disease in body fluids and cells.
The objective of the journal is to publish novel information leading to a better understanding of biological mechanisms of human diseases, their prevention, diagnosis, and patient management. Reports of an applied clinical character are also welcome. Papers concerned with normal metabolic processes or with constituents of normal cells or body fluids, such as reports of experimental or clinical studies in animals, are only considered when they are clearly and directly relevant to human disease. Evaluation of commercial products have a low priority for publication, unless they are novel or represent a technological breakthrough. Studies dealing with effects of drugs and natural products and studies dealing with the redox status in various diseases are not within the journal''s scope. Development and evaluation of novel analytical methodologies where applicable to diagnostic clinical chemistry and laboratory medicine, including point-of-care testing, and topics on laboratory management and informatics will also be considered. Studies focused on emerging diagnostic technologies and (big) data analysis procedures including digitalization, mobile Health, and artificial Intelligence applied to Laboratory Medicine are also of interest.
