Capillaria infection in a 16-year-old girl (Philippines)

Intestinal capillariasis is a rare parasitic disease caused by the nematode Capillaria philippinensis. The disease is primarily endemic in the Philippines, but cases have been reported in other parts of the world. The disease is characterized by severe diarrhea, malabsorption, and electrolyte imbalance, which can lead to life-threatening complications if not treated promptly.

Etiology

Intestinal capillariasis is caused by the ingestion of raw or undercooked fish infected with the larvae of Capillaria philippinensis. The parasite is a small, hair-like nematode that resides in the small intestine of humans. The adult worms produce eggs that are passed in the feces, which can contaminate water sources and infect fish.

Clinical Manifestations

The disease typically presents with chronic diarrhea, abdominal pain, and weight loss. Other symptoms may include anorexia, nausea, and vomiting. In severe cases, patients may develop malnutrition, dehydration, and electrolyte imbalances, which can lead to complications such as cardiac arrhythmia and shock.

Diagnosis

Diagnosis of intestinal capillariasis is made by identifying Capillaria philippinensis eggs or adult worms in stool samples. Other diagnostic methods may include endoscopy and biopsy of the small intestine.

Treatment

Treatment for intestinal capillariasis involves the use of anthelmintic drugs, such as mebendazole or albendazole. In severe cases, hospitalization may be required for rehydration and correction of electrolyte imbalances.

Prevention

Prevention of intestinal capillariasis primarily involves avoiding the consumption of raw or undercooked fish in endemic areas. Improved sanitation and proper cooking of fish can also help to prevent the spread of the disease.
