Summary
Serum fructosamine is not a reliable marker for monitoring blood glucose control in preterm infants. This study found no association between fructosamine levels and hyperglycemia or related complications in premature neonates.
Area of Science:
- Neonatal Medicine
- Pediatric Endocrinology
- Clinical Chemistry
Background:
- Hyperglycemia is a frequent complication in premature infants, necessitating careful management due to its prevalence and adverse effects.
- Serum fructosamine, a marker of average glucose levels over 2-3 weeks, is utilized in diabetic patient monitoring.
Purpose of the Study:
- To assess the physiological characteristics of serum fructosamine in preterm and term neonates.
- To investigate the association between fructosamine levels and hyperglycemia, along with associated morbidities, in preterm infants.
Main Methods:
- Fructosamine levels were measured in extremely premature (22), moderately premature (36), and term (26) neonates during the first week of life.
- Levels were re-assessed in preterm infants at 4 and 7 postnatal weeks.
- Hyperglycemic episodes and major morbidities in preterm infants were analyzed in relation to fructosamine levels.
Main Results:
- Preterm infants exhibited higher initial fructosamine levels compared to term infants, with a subsequent decrease observed postnatally.
- Serum fructosamine levels did not correlate with the incidence of hyperglycemia or its primary morbidities in preterm infants.
Conclusions:
- The study did not establish the utility of serum fructosamine for glycemic control in preterm neonates during the perinatal period.
- Further research may be needed to identify optimal glycemic monitoring strategies for this vulnerable population.

01:29Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:15Hypoglycemia and Glucagon
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
