Insights

Clinical "warning signs" may help identify primary immunodeficiency (PID) in adults with periprosthetic joint infections (PJI). One patient with PJI was diagnosed with PID, suggesting this screening tool

Area of Science:

  • Immunology
  • Orthopedic Surgery
  • Infectious Diseases

Background:

  • Primary immunodeficiency (PID) can predispose individuals to infections.
  • Periprosthetic joint infections (PJI) are serious complications of joint replacement surgery.
  • Screening tools for PID in adult populations are valuable for early diagnosis and management.

Purpose of the Study:

  • To evaluate the utility of ten clinical "warning signs" in identifying potential primary immunodeficiency (PID) among patients with periprosthetic joint infections (PJI).
  • To determine if these warning signs can detect underlying PID contributing to the development of PJI.

Main Methods:

  • A descriptive study analyzed data from an institutional PJI database.
  • 185 patients with PJI and a history of extensive healthcare utilization were included.
  • Retrospective review of medical records assessed the presence of PID "warning signs".

Main Results:

  • 14.5% (27/185) of patients with PJI exhibited one or more PID "warning signs".
  • Most (24/27) had secondary immunodeficiency due to other conditions.
  • Primary immunodeficiency was confirmed in one patient with hypogammaglobulinemia.

Conclusions:

  • Clinical "warning signs" may aid in detecting primary immunodeficiency (PID) in select patients with periprosthetic joint infections (PJI).
  • Identifying PID in PJI patients could impact treatment strategies and outcomes.
  • Further investigation into screening for PID in patients with recurrent infections is warranted.

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

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...

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...

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...

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
