Insights

Patients with diabetes face higher Coronavirus disease 2019 (COVID-19) risks due to physiological factors. Key biomarkers like hypertension and inflammation predict severe COVID-19 outcomes in diabetic individuals.

Area of Science:

  • Endocrinology
  • Virology
  • Immunology

Background:

  • Clinical observations indicate increased Coronavirus disease 2019 (COVID-19) severity in patients with diabetes.
  • Investigating the physiological underpinnings of this observed link is crucial for understanding disease progression.

Purpose of the Study:

  • To explore the physiological pathways connecting diabetes and COVID-19 severity.
  • To identify biomarkers predicting adverse outcomes in diabetic patients with COVID-19.

Main Methods:

  • Publication mining of PubMed data from 2000-2020 to identify common research themes.
  • Knowledge graph extraction to map interconnections between diabetes and COVID-19.

Main Results:

  • Three pathophysiological pathways identified: Angiotensin-converting enzyme 2 dysregulation, liver dysfunction, and chronic systemic inflammation.
  • Biomarkers predicting higher risk include hypertension, elevated alanine aminotransferase, high interleukin-6, and low lymphocyte count.

Conclusions:

  • Identified biomarkers can aid clinical risk assessment for COVID-19 in diabetic and prediabetic patients.
  • Checking medical history for chronic biomarker dysregulation is recommended for newly infected individuals.

Overview of Carbohydrate Metabolism

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Pathophysiology 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,...

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...

Carbohydrate Metabolism

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
