A young lady presented to us with bilateral pitting pedal edema of 2 months duration and laboratory evaluation showed microcytic anemia, low total protein and albumin. Endoscopy and colonoscopy revealed multiple motile worms which were retrieved for species identification. Stool examination revealed polyparasites – Fasciola, Gastrodiscoides, Giardia and Entamoeba.

She improved with praziquantel, albendazole and metronidazole.

Factors favouring the high endemicity are poor hygiene, consumption of undercooked food, the climatic compatibility for the parasites, swine population and usage of fecal manures for farming. A simple use of anti-helminthic or antiprotozoals in areas of high endemicity can prevent poor outcome among these patients. Ann Jose ankara fastrodiscoides.

Intestinal parasitic infections are a major public health problem in developing countries. This is a report of simultaneous infestation with trematodes- Fasciolopsis buskithe largest fluke parasitizing humans; Gastrodiscoides hominisan intestinal fluke infecting people and their livestock, and protozoa- Entamoeba histolytica and Giardia intestinaliswhich cause malabsorption and have high prevalence in the developing countries.


Chief source of human infection include ingestion of contaminants from untreated sewage, a phenomenon particularly common in many developing countries. A 20 year old lady from Bihar, India presented with bilateral pitting pedal edema since 2 months and mild abdominal discomfort with nausea since 1 week. She denied any history of vomitingloose stool or irregular bowel habits and had no other systemic symptoms.

There were no similar complaints in family members. She consumed a predominantly vegetarian diet, which included fish about twice a month and had no history of eating any aquatic plants. Physical examination was unremarkable except for pedal edema. Brownish hyperpigmentation were noted on the extensor aspect of legs Figure 1. Laboratory evaluation revealed microcytic anemia hemoglobin of No peripheral blood eosinophilia was noted.

Cardiac, thyroid and renal functions were normal.

A Description of Gastrodiscoides hominis, from the Napu mouse deer

Abdominal ultrasound revealed mild ascites. Viral markers were negative. Lower limb doppler revealed normal arterial and venous system with diffuse soft tissue edema. During her stay in the ward, after gastrodlscoides post-prandial abdominal discomfort she vomited out a worm. She gave no history of passing worms in stool. Upper GI endoscopy revealed multiple motile hominks ranging from cm in length and 0.

Few adult worms were retrieved and sent for species identification. Colonoscopy also revealed infestation in terminal ileum and in the right colon Gastrodlscoides 3. Few of the samples were also confirmed to be of Gastrodiscoides hominis Figures 7 and 8 by the Department of Veterinary Parasitology, Veterinary College, Bangalore. Stool examination showed bile stained as well as non-bile stained operculated eggs Figures 6 gastrodiscoidees 9ova along with numerous trophozoites and cysts of Giardia intestinalis and Entamoeba histolytica.

The family members were screened and did not harbor the infection. In view of hyper-infestation, she was given anti-helminthic under polyethylene glycol preparation to purge the dead worms to prevent intestinal obstruction. Her stool contained many dead worms for the next three days and she improved symptomatically, with lab values gastrldiscoides rise in serum albumin and was hence discharged. The patient was not available for further follow up.


Aquatic plants with metacercariae on their surface from snails is the major mode of human infection [ 2 ], with drainage of pig excreta in farms being an important factor for maintaining high endemicity [ 3 ].

Infestation is usually asymptomatic, while heavy infection causes diarrhoeavomiting, malabsorption, intestinal obstruction, perforation and eosinophilic leucocytosis [ 45 ]. Gastrodiscoides hominis is a common parasite in humans and pigs in certain parts of India. The planorbid freshwater snails, Helicorbis coenosus shed the cercariae, cercariae encyst to metacercaria on aquatic plants, or in tadpoles, frogs, and clayfish [ 3 ] and ingested metacercaria excyst to flukes, reside in gastrodisdoides cecum and colon leading to mucoid diarrhea.

Gastrodiscoides hominis and Fasciolopsis buski use the same molluscan intermediate host species. The same reason could also explain similar results obtained in human surveys i. Severe Fasciola and Gastrodiscoides infestation is due to repeated consumption of the metacercaria larva from aquatic plants. Prevention of intestinal gastrodkscoides infections requires preventing fecal contamination of gatsrodiscoides where fish and aquatic plants breed.

Education regarding the risks associated with ingestion of raw or insufficiently cooked molluscs and fish is also important. Freezing, smoking, and pickling of fish do not destroy metacercariae [ 8 ]. Giardia intestinalis and Entamoeba histolytica were concomitant protozoan parasites due to similar feco-oral contamination. Infestation with multiple parasites is common in endemic areas. Poor hygiene, lack of education and awareness, use of human feces as manure are important factors in maintaining endemicity.
