Common variable immunodeficiency disorder (CVID), the commonest symptomatic primary antibody deficiency syndrome, is characterised by recurrent bacterial infections, particularly of the upper and lower airways; it is also associated with an increased incidence of autoimmune and neoplastic disorders.CVID has a high prevalence of infectious, inflammatory and neoplastic gastrointestinal diseases. Up to 60% of the patients with non-treated CVID develop diarrhea and 10% associated idiopathic malabsorption with weight loss.The case of a 50-year-old woman with CVID-associated diarrhea, abdominal pain and bloating of one year´s duration is reported. An exhaustive evaluation made for secondary causes of her symptoms was unrevealing; she was treated with loperamide and diet, without improvement. She later followed a course of oral budesonide for 3 months; her clinical symptoms disappeared and her quality of life improved.In conclusion, we report the case of a patient with CVID-related chronic diarrhea who responded well to oral budesonide treatment. This outcome provides the gastroenterologist with a new therapeutic option in this difficult group of patients.
