Giardia lamblia infection was documented by jejunal biopsy in a previously healthy 2-year-old boy with acute onset of hypoproteinemia due to protein-losing enteropathy. All symptoms and abnormal laboratory findings resolved with anti-Giardia therapy. This is only the second case report of giardiasis with documented protein-losing enteropathy. Further application of the fecal alpha 1-antitrypsin assay may help to clarify the relationship between Giardia infection and protein-losing enteropathy and its role in development of malnutrition.

Common variable immunodeficiency is characterized by a primary deficiency in antibody production that is clinically manifested by respiratory recurrent infections and gastrointestinal diseases (infectious, inflammatory and neoplastic). Above 50% of the patients have diarrhea and 10% develop idiopathic malabsorption and weight loss. We present the case of a 34-year-old woman submitted to our service for chronic diarrhea, abdominal pain and bloating and history of recurrent respiratory infections since childhood. The laboratory assessment showed severe hypoproteinemia and confirmed low IgG, IgA and IgM levels. Upper gastrointestinal endoscopy and videocapsule endoscopy showed a nodular duodenum with multiple polypoid-like formations all through the small bowel. Histology confirmed chronic duodenitis and Giardia lamblia infection. With the diagnosis of common variable immunodeficiency, monthly intravenous gammaglobulin infusion was initiated and metronidazole was indicated for Giardia lamblia infection achieving excellent clinical and laboratory response.

An adolescent boy presented to pediatrics outpatient department with complaints of recurrent diarrhea, nausea, vomiting, and pedal edema since 3-4 months, with no relief even after taking treatment. His investigation revealed decreased serum IgA, IgG, and IgM levels with hypoproteinemia. Duodenal biopsy showed features of celiac disease (CD), but tissue transglutaminase IgA was negative. In stool examination, plenty of Giardia lamblia cysts and eggs of Hymenolepis nana were present. He improved on treatment and remained asymptomatic for 4 months. However, he again developed symptoms and succumbed to his illness. In patients of common variable immunodeficiency (CVID), who present with features of CD, coinfection, especially with G. lamblia and other parasites must always be kept in mind. The aim is to report a case of recurrent giardiasis with CVID mimicking CD from Western Rajasthan, India.
