Diabetes Related Deaths in a Tertiary Pediatric Referral Institution in England: The Value of Biochemical Analyses in Post-Mortem Samples

Rahim NS, McTaggart E, Cohen MC

Pediatr Dev Pathol, 2023;26(2):115-123.
PMID: 36755423 DOI: 10.1177/10935266221146045

OBJECTIVES: To establish the incidence of "diabetes-related death" (DRD) in children with known and unknown Diabetes Mellitus (DM) dying unexpectedly, and describe post-mortem (PM) biochemistry findings.
PATIENTS AND METHODS: PM reports from the previous 16-year period were reviewed. Cases of DRD were extracted. All available demographic, clinical, and autopsy data including laboratory analyses was retrieved.
RESULTS: 9/1376 (0.7%) DRD cases were identified. This was attributed to Diabetic Ketoacidosis in 7 and to Death in Bed Syndrome in 2. 4/9 cases were known diabetic and on insulin; whilst in 5/9 cases the diagnosis of DM was at PM. The mean age was 11.6 years (range 2.5-15). At PM, 4 cases were undernourished. The histology demonstrated pancreatic changes in keeping with DM in 3/9 and unremarkable pancreatic findings in 6/9. 3 cases also had autoimmune thyroiditis (1 also had myocarditis and Armanni-Ebstein nephropathy). Toxicological and biochemical analysis showed raised: β-hydroxybutyrate in 6, ketone bodies in 5 cases and raised HbA1c in 3c.
CONCLUSION: Type 1 DM is an infrequent but yet potentially preventable cause of death in children. Our findings highlight the value of routine biochemical and toxicological analysis in all PM examinations of infants and children dying suddenly and unexpectedly.

The fetal sex ratio and metabolic, biochemical, haematological and clinical indicators of severity of hyperemesis gravidarum

PMID: 16709219

The association between female fetal sex and hyperemesis gravidarum is well established in European and North American populations. The association between female fetuses and severity of hyperemesis remains uncertain. A retrospective study based on case notes review of 166 Asian women hospitalised for hyperemesis was performed. Female fetuses were significantly associated with hyperemesis in our population (P= 0.004, OR 1.6, 95% CI 1.2-2.2) as well as associated with severe ketonuria and high urea. When both severe ketonuria and high urea were present at initial hospital admission for hyperemesis, 83% (95% CI 66-93) of the fetuses were female.

Diabetes mellitus (DM) is a chronic disease that can affect metabolism of glucose and other metabolites. In this study, the normal- and obese-diabetic rats were compared to understand the diabetes disorders of type 1 and 2 diabetes mellitus. This was done by evaluating their urine metabolites using proton nuclear magnetic resonance (1H NMR)-based metabolomics and comparing with controls at different time points, considering the induction periods of obesity and diabetes. The biochemical parameters of the serum were also investigated. The obese-diabetic model was developed by feeding the rats a high-fat diet and inducing diabetic conditions with a low dose of streptozotocin (STZ) (25 mg/kg bw). However, the normal rats were induced by a high dose of STZ (55 mg/kg bw). A partial least squares discriminant analysis (PLS-DA) model showed the biomarkers of both DM types compared to control. The synthesis and degradation of ketone bodies, tricarboxylic (TCA) cycles, and amino acid pathways were the ones most involved in the variation with the highest impact. The diabetic groups also exhibited a noticeable increase in the plasma glucose level and lipid profile disorders compared to the control. There was also an increase in the plasma cholesterol and low-density lipoprotein (LDL) levels and a decline in the high-density lipoprotein (HDL) of diabetic rats. The normal-diabetic rats exhibited the highest effect of all parameters compared to the obese-diabetic rats in the advancement of the DM period. This finding can build a platform to understand the metabolic and biochemical complications of both types of DM and can generate ideas for finding targeted drugs.
