Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.5K
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...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.7K
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...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

1.2K
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.

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

2.1K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Infection01:20

Infection

14.0K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

4.8K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Summary
This summary is machine-generated.

Patients with impaired immunity face higher infection risks and diagnostic challenges. General practitioners can assess immunity status, but certain conditions require specialist consultation for optimal infection management and treatment.

Area of Science:

  • Infectious Diseases
  • Immunology
  • Clinical Medicine

Background:

  • An increasing number of patients present with impaired immunity due to factors like medication, comorbidities, and age.
  • Impaired immunity elevates the risk of infections, including opportunistic ones, leading to complications and diagnostic difficulties.

Purpose of the Study:

  • To outline a clinical approach for general practitioners to classify the relevance of impaired immunity.
  • To highlight challenges in infection diagnosis and management in immunocompromised patients.
  • To provide guidance on specialist consultation and antimicrobial strategies.

Main Methods:

  • Clinical parameter-guided classification of impaired immunity into 'clinically irrelevant,' 'limitedly relevant,' or 'potentially serious' categories.
  • Identification of specific challenges, such as the unreliability of C-reactive protein (CRP) with Tocilizumab use.
  • Recommendations for specialist consultation in severe immunosuppression cases.

Main Results:

  • General practitioners can stratify immune impairment using clinical parameters.
  • Tocilizumab interferes with CRP as an infection marker.
  • Prompt specialist involvement is crucial for severe immunosuppression and suspected infections.

Conclusions:

  • Adaptation of antibiotic policies and prophylactic measures, including vaccination, is indicated for immunocompromised patients.
  • Patients with (functional) asplenia require immediate antibiotic treatment for fever pending physician evaluation.
  • A structured approach is necessary for managing infections in patients with impaired immunity.
