Insights

Patients on long-term steroid therapy face higher infection risks, influenced by dose and duration. This includes common bacteria and unusual opportunistic pathogens like fungi and viruses.

Area of Science:

  • Immunology
  • Infectious Diseases
  • Pharmacology

Background:

  • Chronic corticosteroid use is a well-established risk factor for infections.
  • The degree of immunosuppression and susceptibility to pathogens correlates with steroid dosage and treatment duration.

Purpose of the Study:

  • To highlight the increased risk of diverse infections in patients undergoing chronic steroid therapy.
  • To emphasize the need for clinical vigilance regarding both common and opportunistic pathogens in this patient population.

Main Methods:

  • Review of existing literature on infections associated with chronic corticosteroid use.
  • Analysis of pathogen types and risk factors related to steroid therapy.

Main Results:

  • Patients on chronic steroids exhibit heightened susceptibility to a wide spectrum of infections.
  • While pyogenic bacteria are frequent, there is a notable increase in infections caused by intracellular pathogens, fungi, herpes viruses, and parasites.
  • Infection risk is dose-dependent and duration-dependent.

Conclusions:

  • Chronic steroid administration significantly compromises immune defenses, increasing vulnerability to infections.
  • Clinicians must maintain a high index of suspicion for both typical and atypical opportunistic infections in patients on long-term steroids.
  • Proactive consideration of a broad range of pathogens is crucial for effective patient management.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
Skin Diseases and Disorders01:23

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
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 disorders...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
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.

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
