Abstract

Insights

Infections in type 2 diabetes patients are not linked to glycemic control (HbA1c%). However, increased infection risk correlates with more chronic diseases, older age, and longer diabetes duration.

Area of Science:

  • Endocrinology
  • Infectious Diseases
  • Public Health

Background:

  • Type 2 Diabetes Mellitus (DM2) is often associated with increased infection risk, though evidence is limited.
  • Glycemic control is a key factor considered in managing DM2 complications.
  • Understanding infection risk factors in DM2 is crucial for patient management.

Purpose of the Study:

  • To investigate the association between glycemic control (HbA1c%) and infection risk in type 2 diabetes patients.
  • To identify other potential factors contributing to infection incidence in this population.

Main Methods:

  • A 5-year cohort study (1997-2002) involving 740 type 2 diabetes patients.
  • Evaluation of infectious episode incidence rates.
  • Analysis of correlations between infection risk and glycemic control, age, diabetes duration, and comorbidities.

Main Results:

  • No significant correlation was found between higher HbA1c% levels and infection presentation (p=0.33).
  • A direct correlation exists between infection risk and the number of associated chronic diseases (p=0.035), age (p=0.007), and diabetes duration (p=0.012).
  • An unexplained association was observed between more aggressive treatment, higher HbA1c%, and increased infection risk (p=0.038).

Conclusions:

  • Glycemic control (HbA1c%) is not directly associated with infection risk in type 2 diabetes patients.
  • The number of comorbidities and patient age are significant predictors of infection risk.
  • Further research is needed to understand the link between aggressive treatment, glycemic control, and infection risk.

Diabetes 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...
Complications of Diabetes Mellitus01:22

Complications of Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
Hyperglycemia01:29

Hyperglycemia

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...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Type 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...
