Parenteral drug abuse is a leading cause of necrotizing soft-tissue infections (NSTIs), with cases increasing significantly. Early detection and treatment are crucial for survival in these patients.

Area of Science:

  • Infectious Diseases
  • Surgical Infections
  • Public Health

Background:

  • Necrotizing soft-tissue infections (NSTIs) are severe polymicrobial infections.
  • Parenteral drug abuse has been increasingly associated with NSTIs.

Purpose of the Study:

  • To investigate the causes and outcomes of NSTIs.
  • To identify factors influencing patient survival.

Main Methods:

  • Retrospective survey of 45 patients with NSTIs treated between 1990 and 1995.
  • Analysis of causative factors, infection extent, patient health status, and treatment delays.

Main Results:

  • Parenteral drug abuse was the cause in 56% of cases, rising to 75% in recent years.
  • Mortality rate was 27%.

  • Extensive infections and hemodynamic instability predicted poor outcomes.

    • Conclusions:

    • Parenteral drug abuse is a major and increasing cause of NSTIs, reaching epidemic proportions.
    • Survivors had less extensive infections and better hemodynamic stability.
    • Clostridial species were common in drug abuse-related NSTIs, highlighting wound botulism risk.
