title: Chronic Giardiasis in a Case of Common Variable Immunodeficiency (CVID): A Case Report.
abstract: Common Variable Immunodeficiency (CVID) is a primary immunodeficiency characterized by low antibody levels and recurrent infections. This makes an individual more prone to recurrent respiratory and gastrointestinal tract infections. In cases where there is persistent positive finding of intestinal parasites in stool, a high index of suspicion should be raised to rule out immunodeficiency state. Early diagnosis of such cases will help in reducing the morbidity and better management of the patient. A case of CVID in 18-year-old male with recurrent lower respiratory tract infection and chronic diarrhoea due to Giardia lamblia is reported herewith.
