Comprehensive Diagnostic & Therapeutic Reference Profile
Also known as: Ascaris lumbricoides infection, Roundworm infection, Soil-transmitted helminthiasis
Ascariasis is a parasitic infestation caused by the nematode Ascaris lumbricoides. It is the most common human helminth infection globally, transmitted primarily through the ingestion of food or water contaminated with embryonated eggs found in soil.
The disease is caused by Ascaris lumbricoides. Humans serve as the definitive host. Infection occurs via the fecal-oral route, usually through poor sanitation, consumption of unwashed produce, or geophagia (dirt-eating).
Following ingestion, larvae hatch in the small intestine, penetrate the intestinal wall, and migrate via the portal circulation to the liver, then to the lungs. In the lungs, they mature, break into the alveoli, ascend the bronchial tree, are swallowed, and return to the small intestine to mature into adult worms.
Ascariasis affects over 800 million people worldwide, primarily in tropical and subtropical regions. Children aged 2–10 are most susceptible.
A. Early Symptoms
A. Clinical Assessment: History of travel/exposure and symptom progression.
B. Laboratory Testing: Stool O&P, CBC.
C. Imaging Studies: Abdominal X-ray, Ultrasound.
D. Functional Tests: N/A
E. Biopsy Findings: N/A
F. Genetic Testing: N/A
G. Differential Diagnosis: Hookworm, Trichuriasis, Crohn's, Appendicitis.
Stool Microscopy
Type: Stool Examination
Purpose: Detect eggs
Expected Findings: Ascaris eggs
Interpretation: Diagnostic confirmation Complete Blood Count (CBC)
Type: Blood Test
Purpose: Evaluate eosinophilia
Expected Findings: Elevated eosinophils
Interpretation: Indicates helminth presence
Abdominal Ultrasound: Used to visualize adult worms within the bowel lumen or biliary tree (appearing as mobile, hyperechoic structures).
Abdominal X-ray: Indicated for suspected intestinal obstruction; may show "swirling" of worms.
A. Lifestyle Modifications: Hand hygiene, washing produce.
B. Preventive Measures: Sanitation improvement, mass drug administration.
C. Medical Treatment: Albendazole (400mg) or Mebendazole (100mg BID for 3 days).
D. Surgical Treatment: Required for complete bowel obstruction or biliary impaction.
E. Interventional Procedures: Endoscopic removal (ERCP) for biliary ascariasis.
F. Rehabilitation: Nutritional supplementation.
G. Emergency Management: Fluid resuscitation and surgical intervention for peritonitis/obstruction.
Generally excellent with anthelmintic treatment; rapid improvement occurs after worm expulsion.
Mass deworming programs (WHO), improved sanitation, clean water access, and public hygiene education.
The following homeopathic remedies have been historically indicated for symptoms associated with Ascariasis. Selection should be based on individualized symptom totality and constitutional assessment.
