Abstract

Insights

Invasive fungal disease (IFD) is common in critically ill patients with hematological malignancies (HM), leading to longer ICU stays. Hypertension and prolonged mechanical ventilation are key risk factors for IFD.

Area of Science:

  • Critical Care Medicine
  • Hematology
  • Infectious Diseases

Background:

  • Invasive fungal disease (IFD) presents significant challenges for critically ill patients with hematological malignancies (HM).
  • Limited research exists on IFD's clinical characteristics, risk factors, and outcomes in this specific patient group.

Purpose of the Study:

  • To investigate the clinical characteristics, risk factors, and outcomes of IFD in critically ill patients with HM.
  • To identify independent risk factors associated with IFD development in this vulnerable population.

Main Methods:

  • Retrospective study conducted at a tertiary center in China.
  • Inclusion of patients with HM admitted to the intensive care unit (ICU) between 2014 and 2022.
  • Analysis of patient data to determine IFD prevalence, characteristics, and associated factors.

Main Results:

  • IFD was diagnosed in 43.9% of 239 enrolled patients.
  • Patients with IFD experienced significantly longer ICU stays (median 4.9 vs. 2.9 days).
  • Hypertension, mechanical ventilation >48 hours, and delayed ICU transfer were independent IFD risk factors.

Conclusions:

  • IFD is a frequent complication in critically ill HM patients, correlating with extended ICU length of stay.
  • Hypertension, prolonged mechanical ventilation, and delayed ICU transfer are identified as independent risk factors for IFD.
  • Findings highlight the need for targeted preventive strategies and early detection in this high-risk group.

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

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...

Pulmonary Tuberculosis I01:29

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.

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

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...
