We studied a male infant with compound heterozygous ABCC8 mutations (p.Arg826Trp/p.Ile93Thr) causing neonatal diabetes mellitus.He died of ketoacidosis.
Deficiency of beta-ketothiolase (beta-KT, also known as T2, mitochondrial acetoacetyl-CoA thiolase and acetyl-CoA acetyltransferase 1) is a well-described disorder which presents with acute episodic ketoacidosis.
Deficiency of beta-ketothiolase (beta-KT, also known as T2, mitochondrial acetoacetyl-CoA thiolase and acetyl-CoA acetyltransferase 1) is a well-described disorder which presents with acute episodic ketoacidosis.
Deficiency of ACAT1 is an inherited metabolic disorder, which results from a defect in mitochondrial acetoacetyl-CoA thiolase activity and is clinically characterized with patients presenting ketoacidosis.
If beta-KT deficiency is diagnosed early and treated by fasting avoidance and modest protein restriction, ketoacidosis episodes can be prevented and the prognosis is excellent.
The faster metabolism of ethanol and acetaldehyde by the ADH1B*2 allele and ALDH2*1/*1 genotype and higher ketosis levels were associated with higher UA levels in alcoholics, while diabetes and the consumption of sake were negative determinants.
The correlation between levels of ketosis and hypoxic inducible factor-1alpha (HIF-1α), AKT (also known as protein kinase B or PKB) and 5' AMP-activated protein kinase (AMPK) were determined.

Most interestingly, several candidate genes, including previously reported genes (BMP4, HNF4A and APOBR) and newly identified genes (SOCS4, GCH1, ATG14, RGS6, CYP7A1 and MAPK3), are involved in insulin metabolism or lipid metabolism, implicating the contribution of energy-metabolism-associated genes to the genetic basis of KET.

The inverse dose-dependent relationship of osteocalcin and risk of ketosis was present across osteocalcin level quintiles (top quintile as the reference, adjusted odds ratio (95%CI) = 2.56 (0.80-8.17), 3.71 (0.90-15.29), 10.77 (2.63-44.15), 23.81 (4.32-131.17) per osteocalcin quintile respectively).
