Insights

Chronic granulomatous disease (CGD) can present with multifocal osteomyelitis in children. Early diagnosis via blood tests and prompt treatment are crucial for managing this rare immune disorder.

Area of Science:

  • Immunology
  • Pediatrics
  • Genetics

Background:

  • Chronic granulomatous disease (CGD) is a rare primary immunodeficiency.
  • It stems from a defect in phagocyte nicotinamide adenine dinucleotide phosphate (NADPH) oxidase.
  • Recurrent, severe infections are the hallmark clinical presentation of CGD.

Observation:

  • This report details a case of a 22-month-old child.
  • The child presented with multifocal osteomyelitis as an unusual initial symptom of CGD.
  • Septic CGD is an infrequent consideration in pediatric recurrent infections.

Findings:

  • Diagnosis of CGD relies on specific laboratory tests.
  • These include the reduction of tetrazolium nitroblue (NBT), chemoluminescence assays, and molecular genetic analysis.
  • Multifocal osteomyelitis was identified as an inaugural manifestation.

Implications:

  • Prompt diagnosis and intervention are vital for improving long-term outcomes in CGD.
  • Currently, no curative treatment exists for CGD.
  • Management involves aggressive treatment of infections with antibiotics, potential surgical debridement, and long-term antibiotic prophylaxis.

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Tuberculosis01:23

Tuberculosis

Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
