Brief Summary:

In this trial, eligible patients will be randomly assigned to receive a single dose of 400 mg/kg of IVIG or a normal saline infusion as placebo over 4-6 hours, in addition to their usual medications for CDAD. We expect to enroll approximately 40 patients over a period of two years from UPMC Shadyside Hospital, McKeesport Hospital, and St. Margaret's Hospital who are unresponsive to standard antimicrobial therapy for CDAD.

During the course of this study we expect that IVIG group compared with placebo group will have fewer number of stools per day (< 3 per day). Secondary endpoints will include normal WBC count, normal body temperature, 75% reduction in abdominal pain / tenderness, and decrease in length of hospital stay.

Subjects will sign a written informed consent prior to any study procedures. Patients will be monitored closely during the infusion of the study medication and will continue to be monitored on a daily basis up to the time of discharge. Data collection will include vital signs, CBC, stool C. difficile cytotoxin assay, and stool counts before and after therapy.

Primary Outcome Measures :

1. 1) Normalization of WBC's [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will have a normal WBC count 3.8-10.0/CMM
2. 2) Decrease of Number of Loose Stools to <3 Per Day Following Treatment [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will have fewer number of stools per day (<3 per day).

Secondary Outcome Measures :

1. 1) 75% Reduction in Abdominal Pain/Tenderness [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will a 75% reduction in abdominal pain/tenderness
2. 2) Quantity of Anti-C. Difficile Antibodies in Relationship With Recovery of C. Difficile Diarrhea [ Time Frame: during the course of the study ]
   The quantity of anti-C. difficile antibodies with improve in relationship with recovery
3. 3) Correlation Between Antibody Responses as Measured With ELISA (Enzyme Immunoassay) and Recovery of C. Difficile Diarrhea [ Time Frame: during the course of the study ]
   A correlation will occur between antibody responses as measured with ELISA (enzyme immunoassay) and recovery of C. difficile diarrhea.
4. 4) Normalization of Neutrophil Count on CBC With Diff. [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will have normalization of neutrophil count (1.6-6.7)on CBC with diff.
5. 5) Normalization of Body Temperature During a 24 Hour Period [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will have a normal body temperature of 98.6 F.
6. 6) Patients' Length of Hospital Stay [ Time Frame: during the course of the study ]
   During the course of the study, we expect the IVIG group compared to the placebo group will have a decrease in length of hospital stay.
