Immunodeficiency Diseases

3.1K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Immune Response Against Viral Pathogens

2.6K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

1.4K
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.

Area of Science:

  • Psychology
  • Health Sciences
  • Behavioral Science

Background:

  • Problematic internet use (PIU) is increasingly recognized, often co-occurring with psychological distress.
  • While links to mental health are established, PIU's association with physical health, particularly immune function, remains under-investigated.

Purpose of the Study:

  • To examine the relationship between problematic internet usage and self-reported immune function.
  • To investigate the association between PIU and psychological comorbidities including depression, anxiety, social isolation, and sleep problems.
  • To determine if the link between PIU and immune function is independent of psychological comorbidities.

Main Methods:

  • Online survey of 505 participants assessing internet addiction (Internet Addiction Test), psychological variables (Hospital Anxiety and Depression Scales, UCLA Loneliness Questionnaire, Pittsburgh Sleep Quality Index), general health (GHQ-28), and immune function (Immune Function Questionnaire).

Main Results:

  • Approximately 30% of participants exhibited mild or worse internet addiction.
  • Problematic internet use strongly correlated with depression, anxiety, social isolation, and sleep problems.
  • Internet addiction was associated with reduced self-reported immune function, independent of psychological comorbidities, but not general health.

Conclusions:

  • Problematic internet use is linked to poorer self-reported immune function, even when accounting for psychological comorbidities.
  • The findings suggest a potential mediating role of stress and sympathetic nervous system activity in the relationship between PIU and immune suppression.
  • Further research is warranted to explore the physiological mechanisms underlying the impact of PIU on immune health.
