Predictive Value of the Immune Response of the Host in Clostridium Difficile Infections

Not Applicable

Completed

• Conditions: Clostridium Difficile Infection

• Registration Number: NCT01946750
• Lead Sponsor: Versailles Hospital

Brief Summary

Hypothesis: the antibody directed against certain antigens of Clostridium difficile would be predict the Clostridium difficile infection.

This study evaluates the weight of immunity by studying patients with Clostridium difficile infection versus controls (each patient is associated with two controls : diarrheal control without Clostridium difficile, and non-diarrheal control with or without Clostridium difficile). Recurrence and the kinetics of immune response following infection Clostridium difficile are studied by following the patients during three months.

There are also building biological samples collections clinically documented: sera, stool and strains.

Primary Outcome Measures

Name	Time	Method
Serum antibody titers	J-6, J0	Consider the differential distribution of serum antibody titers, comparing experimental cases's sera prior episodes of Clostridium difficile infection (J-6) and the hospitalized controls's sera (J0).

Secondary Outcome Measures

Name	Time	Method
Kinetics of antibody	J-6, J0, J21, J90 and each recurrence	The sera will be included in the analysis of the kinetics appearance of the immune response.
Clinical evolution	J90	Cases and controls : patients will be followed for 3 months to monitor the clinical evolution (or death) after the of Clostridium difficile infection episode and determine the occurrence of any recurrence up to 3 months after the diagnosis.
Antibody titers for each antigen selected	J0	Comparison of antibody titers for each antigen will be selected among different population groups formed : patients with Clostridium difficile infection, asymptomatic carriers patients, non-carriers patients including non-diarrheal and diarrheal (diarrhea due to other causes than Clostridium difficile infection).
Risk factors	3 months	Matching of controls on sex, type of service, age and length of hospital stay.
Molecular typing of Clostridium difficile strains	J0 and each recurrence	Molecular characterization of strains isolated from patients with Clostridium difficile infection (experimental cases) and recurrence, to confirm microbiologically the notion of recurrence after a previous episode or occurrence of a new episode following infection by a new strain of Clostridium difficile.
