Human intestinal capillariasis: diagnosis by jejunal fluid analysis obtained at enteroscopy and reversal of subtotal villous atrophy after treatment

Abstract

A 43-year-old male presented with complaints of watery diarrhea, increasing fatigability, and weight loss. On examination, the patient was malnourished with presence of pallor and pitting pedal edema. Investigations revealed hemoglobin of 9.0 g/dL with hypokalemia and hypoproteinemia. Stool examination and rectal swab on multiple occasions did not reveal any pathogenic ova or cyst. Upper gastrointestinal endoscopy, flexible sigmoidoscopy, and duodenal and rectal biopsy were all normal.
