Collagenous sprue is associated with high morbidity; however, the etiology of this disorder is unclear. Data regarding the pathological and clinical manifestations of patients with collagenous sprue are also limited. We, thus, undertook this study to gain insight into the etiology, disease manifestations and outcomes of collagenous sprue. ⋯ The vast majority of our patients with collagenous sprue had celiac disease. Although, many patients required immunomodulatory therapy for symptom control, a subset responded to gluten-free diet alone. In our experience, collagenous sprue patients had relatively good clinical outcomes.
