Abstract

Insights

Deep cutaneous fungal infections (DCFI) are a growing concern in immunocompromised children, often presenting with skin lesions. Early diagnosis and treatment are critical to reduce high mortality rates associated with these fungal infections.

Area of Science:

  • Pediatric Infectious Diseases
  • Mycology
  • Dermatology

Background:

  • Life-threatening fungal infections are increasing in children due to immunosuppression and broad-spectrum antibiotics.
  • Premature neonates and individuals with compromised skin barriers are at higher risk.
  • Delayed diagnosis of deep cutaneous fungal infections (DCFI) leads to high mortality.

Purpose of the Study:

  • To characterize pediatric patients diagnosed with DCFI.
  • To identify the fungi responsible for DCFI in children.
  • To determine the risk factors associated with DCFI in pediatric cases.

Main Methods:

  • Retrospective medical record review of pediatric patients with DCFI from 1980-2008.
  • Data collected from institutional pathology and microbiology databases.
  • Analysis of patient demographics, clinical presentation, causative fungi, and treatment outcomes.

Main Results:

  • Twenty-six immunocompromised children (mean age 8 years) with DCFI were identified, predominantly with hematologic disorders.
  • Common clinical presentations included necrotic ulcers (42%) and papules (34%).
  • Aspergillus (44%) and Candida (33%) were the most common fungal pathogens identified; 77% of patients recovered, while 23% died.

Conclusions:

  • DCFI must be considered in the differential diagnosis of skin lesions in immunocompromised children.
  • Prompt skin biopsies for histopathology and fungal culture are essential for early diagnosis.
  • Timely treatment is crucial to improve survival rates in pediatric DCFI cases.

Cryptococcal Meningitis01:27

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,...

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...
Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
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...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
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.
Mode of...
