Area of Science:

  • Toxicology
  • Arachnology
  • Clinical Medicine

Context:

  • Reports on lactrodectism, the syndrome caused by Latrodectus spider envenomation, are scarce in the Negev region.
  • This study documents the first reported cases of lactrodectism in adults from the Negev.

Purpose:

  • To describe the clinical presentation and characteristics of lactrodectism in patients bitten by black widow spiders (Latrodectus inactopus) in the Negev.
  • To highlight unique gastrointestinal manifestations observed in these cases.

Summary:

  • Nine adult patients bitten by black widow spiders were hospitalized between 1985-1988.
  • The primary symptoms included restlessness, profuse perspiration, severe abdominal pain, rigidity, and muscular twitching.
  • Two patients experienced significant gastrointestinal involvement, including ileus and gastric dilatation, which may be attributed to the specific venom of Negev black widow spiders.

Impact:

  • This research expands the understanding of Latrodectus envenomation syndromes, particularly in regions with previously undocumented cases.
  • The findings suggest potential regional variations in black widow spider venom composition and its clinical effects.
  • Highlights the importance of recognizing and managing lactrodectism, including its less common gastrointestinal complications.
