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...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

4.9K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

COPD: Pathogenesis and Clinical Features

2.0K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Amyloid Fibrils

12.2K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Pulmonary Tuberculosis I

1.1K
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:

  • Immunology
  • Pathology

Background:

  • Common Variable Immunodeficiency (CVID) is a primary antibody deficiency linked to infections and immune issues.
  • Amyloidosis, a severe complication, rarely involves the lungs in CVID patients.

Purpose of the Study:

  • To review CVID-associated amyloidosis cases.
  • To present a unique case of pulmonary and gastrointestinal amyloidosis in CVID.

Main Methods:

  • Literature search for CVID and amyloidosis case reports and observational studies.
  • Clinical case presentation of a CVID patient with pulmonary and gastrointestinal amyloidosis.

Main Results:

  • Fifteen cases of CVID-associated amyloidosis were identified, predominantly AA type with multi-organ involvement.
  • Only one prior case of pulmonary amyloidosis in CVID was reported; no pulmonary AL amyloidosis without plasma cell dyscrasia.
  • The presented patient developed systemic AL amyloidosis from an initial AA type, progressing rapidly with a fatal outcome.

Conclusions:

  • Consider amyloidosis in CVID patients presenting with unusual symptoms.
  • Distinguishing between AA and AL amyloidosis is crucial for treatment selection.
  • Early diagnosis and appropriate management of amyloidosis in CVID may improve patient outcomes.
