On evaluation, she was found to have low total IgG, with subclass analysis revealing low IgG1 and IgG3.

The role of immunoglobulin infusion in the treatment of recurrent C. difficile is controversial, with some studies revealing no clear evidence of benefit. Our case report suggests that the patients who have underlying IgG deficiency may benefit from immunoglobulin, as this can significantly reduce the incidence of recurrent …
