Recurrent Septic Shock and Syncope: An Unusual Combination.

Immunoglobulin G (IgG) deficiency disorder is a form of dysgammaglobulinemia, where proportional levels of immunoglobulin G isotype is reduced as compared to other immunoglobulin isotypes. Common clinical presentations of IgG deficiency disorder are recurrent sinusitis and/or lower respiratory infections. However, IgG deficiency manifesting as recurrent septic shock in absence of upper and lower respiratory infection has never been reported, in our search for literature from world over. With this rare case, we highlight the importance of investigating IgG levels in clinical scenarios of recurrent sepsis with no known or traceable infective focus.
