Insights

Necrotising fasciitis, a severe infection, is increasingly caused by multiple bacteria, not just Streptococcus. This study found polymicrobial infections and antimicrobial resistance in 19 cases, with a significant mortality rate.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Surgery

Background:

  • Meleney's original description of necrotising fasciitis primarily implicated Streptococcus pyogenes.
  • Subsequent reports confirmed Streptococcus as the predominant pathogen.
  • Recent observations suggest a shift towards other causative organisms.

Purpose of the Study:

  • To analyze recent cases of necrotising fasciitis to determine if the disease entity has changed.
  • To investigate the spectrum of causative organisms and patient demographics.
  • To assess treatment resistance and outcomes in contemporary necrotising fasciitis cases.

Main Methods:

  • Retrospective analysis of 19 necrotising fasciitis cases managed in Orthopaedic Surgery.
  • Data collected over a 24-month period.
  • Evaluation of patient demographics, comorbidities, causative agents, treatment, and mortality.

Main Results:

  • The study included 19 patients aged 19-85 years (average 57.2).
  • Males were predominantly affected (16/19).
  • A high proportion of patients had underlying diseases (16/19).
  • A trend towards polymicrobial infections was observed.
  • Many infections showed resistance to standard antimicrobial therapy.
  • The overall mortality rate was 21.1%.

Conclusions:

  • Necrotising fasciitis may be evolving, with a notable increase in polymicrobial infections.
  • Antimicrobial resistance is a significant concern in managing this condition.
  • The findings highlight the need for updated diagnostic and therapeutic strategies for necrotising fasciitis.

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

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...
Colonisation of Pathogens01:25

Colonisation of Pathogens

Pathogen colonization of host tissues is a critical step in the development of infectious diseases. Various pathogenic microorganisms, including bacteria, fungi, viruses, and protozoa, have evolved complex strategies to attach to, invade, and persist within host environments. These mechanisms enable pathogens to establish infections, evade immune responses, and resist antimicrobial treatments.Attachment to Host CellsIn bacteria, colonization typically begins with adherence to host epithelial...
Determinants of Bacterial Pathogenicity and Virulence01:20

Determinants of Bacterial Pathogenicity and Virulence

Pathogenic bacteria employ a variety of strategies to establish infections, including the secretion of extracellular enzymes that act as potent virulence factors. These enzymes facilitate bacterial colonization of host tissues and help evade immune surveillance. By targeting structural components of host tissues and interfering with immune mechanisms, these enzymes play a pivotal role in disease progression.Extracellular Enzymes Facilitating Tissue Invasion: Several bacterial pathogens secrete...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
