Abstract
Intestinal capillariasis is an uncommon food-borne helminthic infection caused by Capillaria philippinensis. It is classically reported from Southeast Asian countries, but sporadic cases from non-endemic regions, including India, show that the disease may be overlooked in routine clinical practice. We report the case of a 35-year-old male farmer from South India who presented with six months of chronic watery diarrhoea, abdominal pain, and marked weight loss. Clinical examination suggested malnutrition, and laboratory evaluation showed mild anaemia and eosinophilia. Stool microscopy revealed characteristic oval, thick-shelled eggs consistent with Capillaria philippinensis, confirming the diagnosis of intestinal capillariasis. The patient received oral mebendazole at a dose of 200 mg twice daily for 20 days, together with adequate hydration, dietary advice, and nutritional supplementation. During follow-up, there was a clear reduction in stool frequency, improvement in appetite, and gradual recovery of general health. Repeat stool microscopy performed after one month did not reveal any parasitic eggs, indicating parasitological clearance. This case emphasises that intestinal capillariasis should be considered as a possible diagnosis in patients with long-standing diarrhoea, weight loss, and eosinophilia, even in areas where the disease is not commonly reported. Early stool examination, careful dietary history, and timely anti-helminthic therapy can prevent prolonged morbidity and possible complications.
