Enteral nutrition for severe malnutrition Crohn's disease patient: Case report.

INTRODUCTION Crohn's disease (CD) is a chronic systemic inflammatory disease with indefinite remission and relapse cycles, which can result in a high incidence rate of malnutrition. There has been increasing clinical interest in enteral nutrition (EN) as an adjunct treatment for CD. This report aims to present a case of a severely malnourished CD patient given EN support in combination with conventional infliximab (IFX) treatment. PATIENT CONCERNS A 42-year-old CD patient with severe malnutrition. She once weighted 27.5 kg (BMI 11.4 kg/m) with hyponatremia, which may cause sudden death at any time. DIAGNOSIS In this study, the diagnosis of CD made by our gastroenterologist was based on integrating patient symptoms, radiologic findings, and biopsy results. The patient had no differential diagnosis. INTERVENTIONS The patient received EN support and actively followed up for more than 2 years. The patient also received IFX treatment and four surgeries on an as-needed basis to manage her symptoms. OUTCOMES The patient's inflammation and symptoms were finally improved by a combination of enteral nutrition and IFX, and her body weight increased to 44 kg. CONCLUSION The jejunal feeding tube was the starting point of her weight gain and inflammation reduction, which allowed her adequate energy. EN may be a potential complementary therapeutic strategy to manage clinical symptoms of CD and improve severe malnutrition.
