Giardiasis, an intestinal infection, often presents with varied gastrointestinal symptoms like epigastralgia and diarrhea. Early histological diagnosis and nitroimidazole treatment are key for effective management of this parasitic disease.

Area of Science:

  • Gastroenterology
  • Infectious Diseases
  • Parasitology

Background:

  • Giardiasis is a parasitic infection caused by Giardia lamblia.
  • It can manifest with a wide range of gastrointestinal symptoms, often leading to delayed diagnosis.
  • Accurate diagnosis is crucial for effective treatment and patient management.

Purpose of the Study:

  • To analyze the clinical presentation, diagnostic methods, and treatment outcomes of giardiasis.
  • To highlight the importance of considering giardiasis in patients with persistent gastrointestinal symptoms.
  • To recommend optimal diagnostic strategies for identifying Giardia lamblia.

Main Methods:

  • Retrospective study of 125 patients with histologically confirmed giardiasis.
  • Analysis of patient symptoms, diagnostic procedures, and treatment responses.

  • Histological examination of duodenal biopsies for Giardia lamblia detection.

    • Main Results:

    • Common symptoms included epigastralgia (41%), diarrhea (32%), nausea/vomiting (23%), and weight loss (20%).
    • Average diagnostic delay was over 2 years; only 8% had recent travel history.
    • Nitroimidazole treatment achieved symptom relief in 78% of patients.

    Conclusions:

    • Giardiasis should be suspected in patients presenting with unexplained upper abdominal pain, diarrhea, and weight loss.
    • Histological examination of duodenal biopsies, even from macroscopically normal mucosa, is essential for diagnosis.
    • Prompt diagnosis and appropriate antiparasitic treatment lead to high rates of symptom resolution.
