Pulmonary manifestations in hyper IgE syndrome: A case series and review of Indian literature

Abstract

Recurrent pulmonary infections starting from childhood often prompt evaluation for primary immunodeficiency disorders (PIDs). Hyper IgE syndrome (HIES) is a less common PID characterised by recurrent skin and pulmonary infections associated with elevated IgE levels. Staphylococcal infections are more commonly seen in these individuals, resulting in structural lung abnormalities such as pneumatoceles and bronchiectasis. The associated non-immunologic features (characteristic facies, retained primary dentition, scoliosis, osteopenia, and hyperextensible joints) should raise suspicion of this syndrome. We present four cases of HIES and review the pulmonary manifestations in this disease as reported in the Indian literature.
