Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

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...

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

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.
Carbohydrate Metabolism01:36

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 the...
Pulmonary Tuberculosis V01:28

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

Summary

The growing epidemic of type 2 diabetes (T2DM) is linked to a rise in multidrug-resistant tuberculosis (MDR TB). Patients with T2DM were more likely to have MDR TB and adhere to treatment.

Area of Science:

  • Infectious Diseases
  • Endocrinology
  • Public Health

Background:

  • The co-occurrence of tuberculosis (TB) and type 2 diabetes mellitus (T2DM) is a growing global health concern.
  • The increasing prevalence of T2DM may influence the epidemiology of TB, including drug resistance patterns.

Purpose of the Study:

  • To investigate the association between T2DM and multidrug-resistant TB (MDR TB) in patients along the Texas/Mexico border.
  • To examine the impact of T2DM on treatment adherence to Directly Observed Treatment, Short-course (DOTS) therapy.

Main Methods:

  • Retrospective analysis of data from 2878 TB patients.
  • Comparison of MDR TB prevalence and T2DM association between Texas and Mexico cohorts.
  • Statistical adjustment for confounding factors including age, gender, substance abuse, HIV, and prior TB history.

Main Results:

  • Overall MDR TB prevalence was 5.6% (3.4% in Texas, 7.8% in Mexico).
  • T2DM was significantly associated with MDR TB in both Texas (OR 2.1) and Mexico (OR 1.80).
  • Patients with T2DM showed higher compliance with DOTS therapy in Texas (OR 2.4).

Conclusions:

  • T2DM is a significant risk factor for MDR TB infection.
  • Impaired immunity in T2DM may increase susceptibility to resistant TB strains.
  • T2DM patients' improved adherence to DOTS therapy warrants further investigation in MDR TB management.
