Abstract
Objective. Clostridium difficile infection is an increasingly common cause of healthcare-acquired diarrhea. There remains substantial morbidity and mortality, even with current modalities of treatment. The aim of our study was to investigate the role of intravenous immunoglobulin (IVIG) on mortality in patients with severe Clostridium difficile-associated diarrhea (CDAD). Methods. A retrospective chart review of 21 patients with severe CDAD treated with IVIG in our affiliated hospitals from January 2000 to December 2012 was conducted. As a matching control group, we randomly selected 21 patients meeting the definition of severe CDAD from the same period. Data were compared between these groups using appropriate statistical tests. Results. Patients in the IVIG group were older (69.8 vs 60.9 years, p = 0.05) and had a higher severity score (5.4 vs 3.9, p = 0.02). Mortality was lower among those who received IVIG as compared to the group who did not receive IVIG; however not statistically significant (18.2 vs 22.7%, p = 0.51). Conclusion. Our data demonstrate that although the patients who received IVIG had significantly severe infection, there was no difference in the mortality rate. Prospective controlled studies are needed to assess the true benefit of IVIG in patient with severe Clostridium difficle infection.
