M145 MULTIPLE ACYL-COA DEHYDROGENASE DEFICIENCY MASQUERADING AS MYOSITIS IN AN ADULT COMMON VARIABLE IMMUNODEFICIENCY PATIENT

Abstract

Common variable immunodeficiency (CVID) is a heterogeneous primary immunodeficiency characterized by defective B-lymphocyte differentiation, defective antibody production, and inflammation-induced organ damage. Etiologies for myositis associated with CVID are often elusive. The following is a case of late-onset multiple acyl-CoA dehydrogenase deficiency (MADD) mimicking myositis in a patient concurrently diagnosed with CVID.
